Description

The present invention relates to a modular mounting panel system for an electrical distribution board.

Modular devices or installation devices, such as circuit breakers, residual current circuit breakers, time switches, D and DO fuses, DO switch-fuse units, built-in switches and built-in sockets are designed for installation in electrical distributors or installation distributors. Such distributors can be found in practically every electrified building today.

Conventional modular devices are described in particular by the German standard DIN 43 880. The devices with standardized sizes are mounted on top hat rails in a distribution cabinet. The power is tapped from the devices conventionally using screw or spring-loaded terminals.

From the US 3 213 403 A1 A busbar system is also known which comprises several busbars within a housing. Plug-in openings are provided along the housing so that the fingers of a plug-in unit can be inserted into the housing to tap off power.

From the DE 10 2019 109 638 B4 Furthermore, a control cabinet arrangement with a multi-pole contact protection module is known, in which several busbars are accommodated in a touch-safe manner and accessible via contact openings for device adapters. The contact protection module has a modular housing with at least one central module or several identical central modules arranged in a row.

Other similar devices are known from US 11 784 468 B2 and the DE 20 2013 003 925 U1 known.

Based on this prior art, it is an object of the present invention to provide a device carrier module for a mounting panel system for an electrical distribution board and a mounting panel system for an electrical distribution board in order to improve the user-friendliness taking into account the desired applications.

This object is achieved by a device carrier module according to claim 1, a mounting panel system according to claim 14 and a mounting panel system according to claim 17. Claims 2 to 13 relate to particularly advantageous realizations of the device carrier module according to claim 1. Claims 15 and 16 relate to particularly advantageous realizations of the mounting panel system according to claim 14.

According to the present invention, a device carrier module for a mounting panel system for an electrical distributor comprises a first side wall and a second side wall, which are arranged on opposite sides of the device carrier module and each extend at least partially or completely in a longitudinal direction or substantially in a longitudinal direction of the device carrier module. The device carrier module can be made at least partially or completely from an electrically insulating material (e.g. from a plastic). The device carrier module comprises one or more conductor insertion tracks, which extend in the longitudinal direction or substantially in the longitudinal direction of the device carrier module and are designed for inserting and/or detachably fastening one or more conductor rails. If the device carrier module comprises at least two conductor insertion tracks, two adjacent conductor insertion tracks are separated from one another by an electrically insulating separating track. However, it is also possible for the device carrier module to comprise only one conductor insertion track, so that there are no two adjacent conductor insertion tracks of the device carrier module and the above feature is thus not present. For example, the device carrier module comprises two conductor insertion tracks for inserting two conductor rails of a single-phase connection, four conductor insertion tracks for inserting four conductor rails corresponding to the neutral conductor N and the three outer conductors L1, L2, L3 of a three-phase connection, or a multiple of three conductor insertion tracks for inserting a multiple of three conductor rails, each corresponding to the outer conductors L1, L2, L3 of a three-phase connection. The conductor rails can in particular be electrical conductors, preferably copper conductors. Alternatively or additionally, the one or more conductor insertion tracks can be configured for inserting and/or detachably fastening one or more other lines, in particular signal lines or data lines. The signal lines or data lines can in particular be inserted into the free conductor insertion tracks, i.e. i.e. in the conductor insertion paths in which no conductor rails are inserted. This allows the functionality of the distributor to be expanded and user-friendliness to be further increased.

The device carrier module further comprises one or more electrically insulating covers for covering, preferably for covering in a touch-safe manner, the one or more conductor insertion paths or the one or more conductor rails inserted in the setting tracks.

In addition, the device carrier module comprises one or more first slots; and one or more second slots, which are arranged at a predetermined distance in the longitudinal direction from the one or more first slots. In particular, each second slot can be arranged at a predetermined distance in the longitudinal direction from a corresponding first slot. The predetermined distance between a first slot and a second slot can in particular correspond to a height of a DIN rail device module that can be inserted into an operating position between a first connection module and a second connection module, which can each be plugged into the device carrier module at the first or second slot. In the operating position, the DIN rail device can be fastened to a device carrier module or to the mounting panel system or locked to it. The number of first or second slots can correspond to a number of installation rows of the electrical distributor and in particular be equal to a number of top hat rails to which the device carrier modules can each be locked, as described in more detail below. For example, each device carrier module can comprise three first and three second slots, four first and four second slots, five first and five second slots, or six first and six second slots, corresponding to three, four, five, or six parallel DIN rails.

The device carrier module further comprises one or more first transverse connecting elements and one or more second transverse connecting elements, which are designed such that the device carrier module and a first further device carrier module can be releasably fastened or latched or automatically latched to one another via the one or more second transverse connecting elements of the device carrier module and the one or more first transverse connecting elements of the first further device carrier module, so that: the first further device carrier module is arranged offset or displaced relative to the device carrier module in a transverse direction, wherein the transverse direction runs perpendicular or substantially perpendicular to the longitudinal direction, and a conductor insertion track of the device carrier module and an adjacent conductor insertion track of the first further device carrier module are separated from one another by an electrically insulating separating track. At least part of this electrically insulating separating wall can be formed by at least part of the second side wall of the device carrier module and at least part of the first side wall of the first further device carrier module; Alternatively, this electrically insulating partition wall can comprise at least part of the second side wall of the device carrier module and at least part of the first side wall of the first further device carrier module. When the device carrier module and the first further device carrier module are fastened to one another, the second side wall of the device carrier module can at least partially or completely rest against the first side wall of the first further device carrier module.

The device carrier module according to the invention enables flexible, simple, safe and lightning-fast assembly of an electrical distributor or an assembly panel for an electrical distributor. For this purpose, depending on the desired application, one or more device carrier modules can be provided, each with a corresponding number of conductor insertion tracks. In the case of several device carrier modules, these can be attached to one another using the corresponding cross-connection elements. Then, for example, one or more connection modules can be plugged into the one or more first or second slots on the respective device carrier modules and, for example, one or more DIN rail device modules can be inserted into their respective operating positions by moving relative to the one or more plugged-in connection modules along an insertion direction towards the device carrier modules. The plugged-in connection modules can be used to electrically connect the DIN rail device modules to other DIN rail device modules or to conductor rails that are inserted into the device carrier module or to a neutral conductor rail that is arranged in or on a device carrier module, as described in more detail below. This means that the electrical distributor can be installed flexibly, easily, safely and very quickly without the need for special installation tools or special installation skills. In particular, no power taps using screw or spring-loaded terminals and no complicated conductor routing between different DIN rail devices are required, as is the case with conventional electrical distributors. The electrical distributor can therefore also be installed without any problems by a layperson or user of the electrical distributor. Furthermore, an electrical distributor installed in this way can be expanded as required by attaching additional device carrier modules and/or made smaller as required by removing already attached device carrier modules. This improves user-friendliness, taking into account the desired applications. Furthermore, the device carrier module according to the invention can be manufactured industrially, ie the pre-assembly of the electrical distributor can be industrialized. This makes the electrical Distributor, which only has to be assembled by the user from the modules, is more cost-effective.

In a preferred embodiment, the one or more first slots and the one or more second slots each comprise one or more device carrier plug-in elements, which are each arranged in or on a separating track. The one or more first slots and/or the one or more second slots or the one or more device carrier plug-in elements can be designed as plug-in recesses or plug-in holes, into which corresponding connecting plug-in elements of a connecting module, which are designed as plug-in projections, can be inserted. The plug-in recesses or plug-in holes are preferably L-shaped. Conversely, however, the connecting plug-in elements of the connecting module can also be designed as plug-in recesses or plug-in holes and the slots or device carrier plug-in elements of the device carrier module can be designed as plug-in projections. The arrangement of the device carrier plug-in elements in or on a separating track enables a particularly secure, compact and space-saving structure of the device carrier module. The L-shape of the plug-in recesses allows, for example, For example, the connecting plug elements of a connecting module, which are designed as plug projections, are inserted into the respective L-shaped plug recesses by an L-shaped movement. For example, the connecting module can first be inserted along the insertion direction and then shifted or moved along the longitudinal direction or the transverse direction relative to the device carrier module. This achieves a particularly simple, stable and secure attachment of the connecting module to the respective device carrier module.

In a preferred embodiment, the one or more first transverse connecting elements comprise one or more projections and the one or more second transverse connecting elements comprise one or more recesses. Alternatively or additionally, the one or more first transverse connecting elements comprise one or more recesses and the one or more second transverse connecting elements comprise one or more projections. In particular, the one or more first transverse connecting elements can be arranged on the first side wall and/or the one or more second transverse connecting elements can be arranged on the second side wall. The one or more projections are preferably T-shaped. The first further device carrier module can thus be fastened to the device carrier module, e.g. by arranging the first further device carrier module offset in the transverse direction relative to the device carrier module and displacing or moving it relative to the device carrier module along the insertion direction, so that in the fastened state the one or more projections engage in the one or more recesses. Due to the T-shape of the one or more projections, in particular the first additional device carrier module can be fixed relative to the device carrier module in the longitudinal direction and in the transverse direction, so that a secure fastening of the first additional device carrier module to the device carrier module is achieved.

The device carrier module preferably comprises one or more first longitudinal connecting elements and one or more second longitudinal connecting elements, which are designed such that the device carrier module and a second further device carrier module can be releasably fastened or latched or automatically latched to one another via the one or more second longitudinal connecting elements of the device carrier module and the one or more first longitudinal connecting elements of the second further device carrier module, so that the second further device carrier module is arranged offset in the longitudinal direction relative to the device carrier module. Particularly preferably, the one or more first longitudinal connecting elements are arranged on a first edge section, e.g. on a lower edge section, of the device carrier module, and the one or more second longitudinal connecting elements are arranged on a second edge section opposite the first edge section, e.g. on an upper edge section, of the device carrier module. The device carrier module and the second additional device carrier module can in particular be fastened to one another in the longitudinal direction in such a way that the conductor insertion tracks of the device carrier module are extended or continued in the longitudinal direction by the conductor insertion tracks of the second additional device carrier module. Thus, the conductor rails arranged in the conductor insertion tracks of the device carrier module and the conductor rails arranged in the conductor insertion tracks of the second additional device carrier module can also be fastened to one another and/or brought into contact with one another in order to form conductor rails extended in the longitudinal direction. Thus, several device carrier modules can be fastened to one another in the longitudinal direction and electrically connected in order to enlarge the resulting mounting panel of the electrical distributor and, depending on the desired application, to mount a higher number of connection modules and/or series-mounted device modules on the mounting panel. This achieves a flexible and individually adaptable assembly of the electrical distributor.

For example, the one or more first longitudinal connecting elements can comprise one or more fastening pins or pin elements and the one or more second longitudinal connecting elements can comprise one or more fastening slots or openings. Alternatively or additionally, the one or more first longitudinal connecting elements can comprise one or more fastening slots or openings and the one or more second longitudinal connecting elements can comprise one or more fastening pins or pin elements. When the device carrier module and the second further device carrier module are fastened to one another, the one or more fastening pins can preferably engage in the one or more fastening slots in a form-fitting manner. In this way, a particularly simple, stable and secure assembly of several device carrier modules to one another in the longitudinal direction is achieved.

In a preferred embodiment, the one or more electrically insulating covers comprise one or more coding elements which are arranged and/or shaped and/or dimensioned such that they each encode a corresponding DIN rail device module from one or more different DIN rail device modules and/or an orientation of a corresponding DIN rail device module, wherein the one or more coding elements are preferably designed as one or more projections for engaging, in particular positively engaging, in one or more recesses of the corresponding DIN rail device module or as one or more recesses for engaging, in particular positively engaging, one or more projections of the corresponding DIN rail device module. Alternatively or additionally, the one or more coding elements can be configured such that they each encode a current or a voltage of a corresponding DIN rail device module.

The one or more coding elements can in particular be arranged and/or shaped and/or dimensioned such that: if the DIN rail device module has a first orientation relative to the device carrier module, the DIN rail device module can be inserted into the operating position and can preferably be locked to the device carrier module in the operating position; and if the DIN rail device module has a second orientation relative to the device carrier module that is different from the first orientation, the DIN rail device module cannot be inserted into the operating position. The second orientation of the DIN rail device module can in particular be rotated by 180° about the insertion direction relative to the first orientation. This means that the DIN rail device module that has the second orientation can be rotated by 180° about the insertion direction relative to the DIN rail device module that has the first orientation, in particular such that the input and output contacts of the DIN rail device module are arranged in reverse. This ensures that the DIN rail device module can only be inserted into the operating position if it has the correct orientation relative to the device carrier module, so that in particular the desired connection of the input or output contacts of the DIN rail device module can be established, e.g. with conductor elements of the respective connection modules. This provides protection against incorrect insertion of the DIN rail device modules, in particular an anti-twist device. This can prevent damage to the DIN rail device system due to accidental insertion of the DIN rail device module with an incorrect orientation. This is particularly advantageous if the DIN rail device system is installed by a layperson or user of the DIN rail device system. This further increases the user-friendliness of the DIN rail device system. The coding elements for different current strengths or voltages described above also ensure that only suitable DIN rail device modules, in particular DIN rail device modules with a suitable current strength or voltage, can be installed at each position on the mounting panel system. Incorrect installation of unsuitable switching devices or DIN rail device modules can thus be completely ruled out, thus further increasing user-friendliness and safety.

Alternatively or additionally, the one or more coding elements can be arranged and/or shaped and/or dimensioned in such a way that: the DIN rail device module can be inserted into the operating position and can preferably be locked into the device carrier module in the operating position; another DIN rail device module can be inserted into another operating position; however, the DIN rail device module cannot be inserted into the other operating position (of the other device carrier module) and/or the other DIN rail device module cannot be inserted into the operating position (of the device carrier module). This ensures that each DIN rail device module can only be inserted into its corresponding operating position (or into one of several corresponding operating positions) and cannot be accidentally inserted into the operating position of another DIN rail device module. This provides protection against incorrect insertion of the DIN rail device modules, in particular preventing the DIN rail device modules from being mixed up. This can prevent damage to the DIN rail device system. due to incorrect arrangement of the DIN rail device modules during installation can be prevented. This is particularly advantageous if the DIN rail device system is installed by a layperson or user of the DIN rail device system. This further increases the user-friendliness of the DIN rail device system.

In a preferred embodiment, center lines of each two adjacent conductor insertion tracks of the device carrier module are the same distance from one another. The distance can be, for example, 18 mm, corresponding to the division unit according to the DIN 43 880 standard. In this respect, the mounting panel system according to the invention can be compatible with conventional distributors and, for example, can be installed in existing control cabinets. However, the distance can also be greater than 18 mm, for example 27 mm, in order to offer more space for the installation of larger DIN rail mounted devices, depending on the desired application, or less than 18 mm to enable a more compact and space-saving distributor. The equal distance between the center lines of the device carrier module can simplify the manufacture of the device carrier module and reduce the cost of the distributor. If different distances between center lines are required depending on the desired application, this can still be realized, e.g. B. by attaching together an equipment carrier module having a first centerline spacing and another equipment carrier module having a second centerline spacing different from the first spacing, as described in more detail below.

The mounting panel system can also comprise the plurality of conductor rails. The plurality of conductor rails are preferably plate-shaped and/or strip-shaped. The conductor rails can thus be inserted or fastened particularly stably into the conductor insertion tracks and can be contacted particularly securely by conductor ends of the conductor elements of the connection modules. Furthermore, the plate-shaped conductor rails can be produced efficiently and cost-effectively.

Preferably, the mounting panel system further comprises one or more conductor elements or tap springs or contact fingers, each of which has a first conductor end and a second conductor end, wherein the one or more conductor elements are fastened to the one or more conductor rails, in particular to one or more notches of the one or more conductor rails, so that the second conductor ends contact the one or more conductor rails and the first conductor ends protrude from openings in the one or more covers. In particular, the one or more conductor elements can be arranged to be rotatable relative to the one or more conductor rails, in particular to be rotatable about the respective second conductor ends.

Particularly preferably, the one or more conductor elements are arranged to be elastically deformable relative to the one or more conductor rails and can assume respective rest positions, so that when the one or more conductor elements are moved, in particular rotated, out of their respective rest positions, a restoring force acts on the one or more conductor elements, which moves, in particular rotates, the one or more conductor elements back to their respective rest positions. Alternatively or additionally, the one or more conductor elements can be spring-loaded in relation to the one or more conductor rails, the spring force corresponding to the restoring force. Preferably, the one or more conductor elements are perpendicular to the one or more conductor rails in their respective rest positions. The conductor elements can, for example, be inserted into the connection housing of the feed module when plugging a feed module onto the device carrier module, so that the first conductor ends of the conductor elements can be contacted through corresponding openings in the connection housing. Furthermore, since the conductor elements are arranged to be rotatable about the second conductor ends relative to the corresponding conductor rails, the first conductor ends can be preloaded against one or more contacts of a DIN rail device module by means of spring forces, as described in more detail below.

Preferably, the plurality of conductor rails each have a fastening section for fastening the conductor rail to a corresponding conductor insertion track, e.g. by means of a latching or snap connection, and a contact section for contacting the second conductor end of a corresponding conductor element. The conductor rails can have different thicknesses; however, in order for the conductor rails to be used with uniform device carriers and with uniform conductor elements of a predetermined height, for each conductor rail, a bottom side of the fastening section with which the conductor rail is fastened to the conductor insertion track and a top side of the contact section to which the corresponding conductor element is fastened must have a predetermined distance from one another. By using conductor rails of a small thickness, material and costs can be saved in particular, while by using conductor rails of a greater thickness, the stability and current-carrying capacity of the conductor rails can be improved in particular.

In a preferred embodiment, the device carrier module comprises one or more locking units for locking or automatically locking the respective device carrier module to one or more parallel top hat rails, preferably in such a way that the one or more top hat rails run parallel or essentially parallel to the transverse direction. The mounting panel system can thus be attached to the top hat rails particularly easily, quickly and stably. Furthermore, for example, the connection modules and the series-mounted device modules that are plugged or inserted into the device carrier modules do not themselves have to be attached to the top hat rails, which further simplifies the assembly of the electrical distributor. The locking units can in particular be designed and dimensioned in such a way that the device carrier modules can be inserted into the existing control cabinets with top hat rails, e.g. on several, in particular three, parallel top hat rails with a width of 35 mm with a center-to-center distance between rails of 150 mm.

Preferably, the one or more locking units each comprise a first locking element; a second locking element which is arranged to be movable back and forth relative to the first locking element along the longitudinal direction of the device carrier module between an arrangement position for arranging the device carrier module relative to a top hat rail so that the top hat rail can be positioned between the first locking element and the second locking element, and a clamping position for clamping or clamping the top hat rail between the first locking element and the second locking element; and a locking spring element which is configured such that it preloads the second locking element in the direction of the first locking element, preferably preloads the second locking element in any position in the direction of the first locking element. The locking spring element can be formed in one piece with the second locking element and made of plastic, for example, in order to save manufacturing costs. The mounting panel system can thus be attached to the top hat rails particularly easily, quickly and stably, thereby further increasing user-friendliness.

According to the present invention, a mounting panel system for an electrical distributor comprises the device carrier module and the first further device carrier module, wherein the device carrier module and the first further device carrier module are releasably fastened to one another via the one or more second cross-connecting elements of the device carrier module and the one or more first cross-connecting elements of the first further device carrier module.

In a preferred embodiment, a distance between center lines of two adjacent conductor insertion tracks of the device carrier module is different from a distance between center lines of two adjacent conductor insertion tracks of the first additional device carrier module. As a result, series-mounted device modules of a first width can be mounted on the device carrier module and series-mounted device modules of a second width can be mounted on the first additional device carrier module, wherein the second width is different from the first width. Alternatively, the distance between center lines of two adjacent conductor insertion tracks of the device carrier module can be equal to the distance between center lines of two adjacent conductor insertion tracks of the first additional device carrier module. The electrical distributor can thus be flexibly assembled from the same or different modules depending on the desired application.

In a preferred embodiment, the number of conductor insertion tracks of the device carrier module is not equal to the number of conductor insertion tracks of the first additional device carrier module. As a result, series-mounted device modules with a total of a first number of poles can be mounted on the device carrier module and series-mounted device modules with a total of a second number of poles can be mounted on the first additional device carrier module, wherein the second number of poles can be different from the first number of poles. Alternatively, the number of conductor insertion tracks of the device carrier module can be equal to the number of conductor insertion tracks of the first additional device carrier module. The electrical distributor can thus be flexibly assembled from the same or different modules depending on the desired application. Particularly preferably, the number of conductor insertion tracks of the device carrier module multiplied by the distance between center lines of two adjacent conductor insertion tracks of the device carrier module is equal to the number of conductor insertion tracks of the first additional device carrier module multiplied by the distance between center lines of two adjacent conductor insertion tracks of the first additional device carrier module. The device carrier module and the first additional device carrier module can thus have the same dimension in the transverse direction, making the manufacture, storage and transport of the device carrier modules more efficient and more cost-effective.

According to the present invention, a mounting panel system for an electrical distributor comprises the device carrier module and the second further device carrier module, wherein the device carrier module and the second further device carrier module are connected via the one or more second longitudinal connecting elements of the device carrier module and the one or more first longitudinal connecting elements of the second further device carrier module are detachably fastened to one another. Preferably, the distance between center lines of two adjacent conductor insertion tracks of the device carrier module is equal to the distance between center lines of two adjacent conductor insertion tracks of the second further device carrier module, and preferably the number of conductor insertion tracks of the device carrier module is equal to the number of conductor insertion tracks of the second further device carrier module. Thus, the one or more conductor insertion tracks of the device carrier module can be extended or continued in the longitudinal direction by the one or more conductor insertion tracks of the second further device carrier module. Thus, the one or more conductor rails arranged in the one or more conductor insertion tracks of the device carrier module and the one or more conductor rails arranged in the one or more conductor insertion tracks of the second further device carrier module can also be fastened to one another and/or brought into contact with one another in order to form conductor rails extended in the longitudinal direction. In particular, the mounting panel system can comprise the device carrier module, the first additional device carrier module and the second additional device carrier module. This means that the electrical distributor can be mounted flexibly depending on the desired application.

In this embodiment, the modular mounting panel system comprises three equipment carrier modules 3: one in 2 left-hand device carrier module 3 (hereinafter referred to as “left device carrier module 3”), a 2 centrally arranged equipment carrier module 3 (hereinafter referred to as “central equipment carrier module 3”) and a 3 right-hand device carrier module 3 (hereinafter referred to as “right device carrier module 3”). The left and middle device carrier modules 3 and the middle and right device carrier modules 3 are each arranged in the transverse direction (horizontal direction in 2 ) are attached to one another to form a mounting panel or a mounting panel system for an electrical distributor. The device carrier modules 3 each contain three locking units for attaching the mounting panel to three parallel top hat rails 7.

In this embodiment, the modular DIN rail device system further comprises three installation rows, for example an upper and a middle (in 2 ) installation row with one fuse switchgear module 1a, one residual current device module 1b and six single-pole LS protection device modules 1c as well as a lower (in 2 ) installation row with a fuse switching device module 1a, an residual current device module 1b and a three-pole DIN rail mounted device module 1d. The DIN rail mounted device modules 1 are each inserted in their respective operating positions between two connection modules 2 which are plugged onto the device carrier modules 3. In this embodiment, each of the three installation rows contains four connection modules 2: a feed-in module 2a which is mounted or plugged onto the left device carrier module 3, a first transverse displacement module 2b which is mounted on the left and the middle device carrier module 3, a second transverse displacement module 2b which is mounted on the middle and the right device carrier module 3, and an output module 2c which is mounted on the right device carrier module 3.

In this embodiment, the left device carrier module 3 and the one with The right device carrier module 3 has four conductor insertion tracks 31, while the right device carrier module 3 has six conductor insertion tracks 31. The conductor insertion tracks 31 each extend in the longitudinal direction (vertical direction in 2 ). The distance between the center lines of two adjacent conductor insertion tracks 31 is, for example, 27 mm for the left device carrier module 3 and the central device carrier module 3 and 18 mm for the right device carrier module 3. In this case, each of the three device carrier modules 3 has the same dimension in the transverse direction, namely 4 × 27 mm = 6 × 18 mm = 108 mm.

In the four conductor insertion tracks 31 of the left device carrier module 3, four conductor rails 5 are arranged, which correspond to the neutral conductor N and the three outer conductors L1, L2 and L3 of a three-phase connection. The conductor rails 5 are covered by electrically insulating covers 36 and are therefore in 1A to 5B not visible (but see 22A and 22B , where the electrically insulating covers 36 are removed). The power is transmitted to the conductor rails 5 via a power feed block with four input terminals (clamping screws) 8, which in this embodiment is attached to an upper section of the left device carrier module 3 (in 2 top left). For each installation row, the current is conducted from the conductor rails 5 via conductor elements 23, which are attached to the conductor rails 5 and arranged in the feed-in module 2a, through the fuse switching device module 1a to the first transverse displacement module 2b. The first transverse displacement module 2b conducts the current further along the transverse direction (perpendicular to the longitudinal direction) from the left device carrier module 3 to the central device carrier module 3. From there, the current is conducted through the residual current device module 1b to the second transverse displacement module 2b. The second transverse displacement module 2b conducts the current further along the transverse direction from the central device carrier module 3 to the right device carrier module 3. From there, the current is conducted through the DIN rail device modules 1 installed on the right device carrier module 3 (ie the six LS protection device modules 1c of the upper or middle installation row or the three-pole DIN rail device module 1d of the lower installation row) to the respective output module 2c and from there via output terminals 9 to the consumer devices. The right device carrier module 3 further comprises output conductor elements which connect the consumer devices to a neutral conductor rail 6 in order to close the circuit between the distributor and the consumer devices. The neutral conductor rail 6 can be arranged at least partially within the output module 2c, as described in more detail below (see 22A to 23D ). Alternatively, the neutral conductor rail 6 can also be inserted into a corresponding neutral conductor insertion track of a device carrier module 3, which runs in the transverse direction.

In 5A to 5C It can also be seen that the connection modules 2 have coding pins 27 for engaging in corresponding coding slots 15a, 15b of the DIN rail device modules 1a to 1d (see 27A and 27D to 27F) included. As in 5C As shown by dashed arrows, the coding pins 27 of two opposite connection modules 2 (each of which is plugged into a first slot 35a and a corresponding second slot 35b) for the central device carrier module 3 are arranged relative to each other in the longitudinal direction (from top to bottom in 5C : vertical pins) to code the residual current device module 1b; for the left device carrier module 3 relative to each other in a diagonal direction (from top left to bottom right in 5C : diagonal pins) to code the fuse switchgear module 1a; and for the right device carrier module 3 in an opposite diagonal direction (from top right to bottom left in 5C : counter-diagonal pins) to code the circuit breaker protection device modules 1c or the three-pole DIN rail mounted device module 1d. When the respective DIN rail mounted device module 1a to 1d is in the operating position, the coding slots 15a, 15b are arranged in the longitudinal direction, the diagonal direction or the opposite diagonal direction, as shown in 27A and 27D to 27F can be seen. Furthermore, in 5A to 5C It can be seen that the electrically insulating covers 36 can contain coding elements 361. In particular, the electrically insulating cover 36, which is shown in 5A to 5C arranged at the bottom right, two coding elements 361 to code the further DIN rail mounted device 1d. These are shown as two in the top view of 5C rectangular projections for engaging in corresponding recesses of the further DIN rail device module 1d. However, the coding elements can have other shapes in plan view than rectangles, e.g. squares, triangles, circles and ellipses, in order to code corresponding DIN rail device modules or their orientations in the operating position.

6A shows a cross-sectional view along AA in 2 . 6B shows the enlarged section X from 6A . 6C shows the enlarged section Y from 6B . The DIN rail device module 1 comprises a DIN rail device functional unit (arranged inside the DIN rail device module 1, not shown), an electrically insulating DIN rail device housing 11, one or more first contacts 13a which are arranged on a first side (right side in 6A , 6B) of the row built-in device module 1, and one or more second contacts 13b, which are arranged on a second side (left side in 6A , 6B) of the DIN rail device module 1, which is opposite the first side (see also 27A , 27B and 27C ). The connection module 2 comprises an electrically insulating connection housing 21, one or more connection plug elements 22 for plugging or detachably fastening the connection module 2 onto the mounting panel or onto one or more device carrier modules 3 and for detaching the connection module 2 from the mounting panel or from the one or more device carrier modules 3, as well as one or more conductor elements 23, each of which has a first conductor end 231a and a second conductor end 231b, wherein the first conductor end 231a and the second conductor end 231b can each be contacted via a corresponding opening in the connection housing 21 (see 17A until 19D ).

6A also shows a contact protection cover 182 (or cover hood 182 or panel 182) of a control cabinet in which the DIN rail device system is installed. In this case, the contact protection cover 182 rests on the hook elements 18 or on corresponding support surfaces of the hook elements 18 of the DIN rail device modules 1. The contact protection cover 182 has openings from which the DIN rail device modules 1 protrude in their respective operating positions, as shown in 6A The openings of the contact protection cover 182 have the same or essentially the same size and shape as the cross-sections (in plan view) of the corresponding DIN rail device modules 1. The DIN rail device modules 1 can be dimensioned such that they can be installed in conventional control cabinets with conventionally dimensioned contact protection covers 182. If, however, the DIN rail device modules 1 have different dimensions, the dimensions of the openings of the contact protection cover 182 can be adapted to the dimensions of the DIN rail device modules 1, so that the DIN rail device modules 1 can be installed in the control cabinet with the adapted contact protection cover 182. Please note that in the other figures, except 6A the contact protection cover 182 was omitted.

In 6A and 6B In particular, a feed-in module 2a and a transverse displacement module 2b are shown, each of which is plugged onto the mounting plate as described above, as well as a DIN rail device module 1, which is arranged to be movable relative to the two connection modules 2 along an insertion direction and can be inserted into an operating position by moving along the insertion direction towards the mounting plate and can be removed from the operating position by moving along the insertion direction away from the mounting plate. In this embodiment, the insertion direction (vertical direction in 6A , 6B) perpendicular to the mounting panel. In this embodiment, the DIN rail device module 1 is inserted between the feed module 2a and the transverse displacement module 2b and is locked in the operating position with the two connection modules 2, so that the first contacts 13a (e.g. input contacts) of the DIN rail device module 1 contact the first conductor ends 231a of a conductor element 23 arranged in the feed module 2a, and the second contacts 13b (e.g. output contacts) of the DIN rail device module 1 contact the first conductor ends 231a of a conductor element 23 arranged in the transverse displacement module 2b. The feed module 2a is an example of the connection module 2 and the transverse displacement module 2b is an example of the further connection module 2.

In this embodiment, the feed module 2a comprises first contact spring elements 26a which are configured such that when the DIN rail device module 1 is in the operating position (as in 6A , 6B shown), the first contacts 13a of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the feed module 2a are prestressed against each other by means of spring forces of the first contact spring elements 26a. The first contact spring elements 26a are fastened in this embodiment on the one hand to the connection housing 21 and on the other hand to the first conductor ends 231a of the conductor elements 23 of the feed module 2a. The spring forces of the first contact spring elements 26a in this embodiment are perpendicular to the insertion direction (ie the spring forces act in 6A , 6B in the horizontal direction). Furthermore, the transverse displacement module 2b comprises second contact spring elements 26b, which are configured such that when the DIN rail device module 1 is in the operating position, the second contacts 13b of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the transverse displacement module 2b are prestressed against each other by means of spring forces of the second contact spring elements 26b. In this embodiment, the second contact spring elements 26b are attached on the one hand to the connection housing 21 and on the other hand to the first conductor ends 231a of the conductor elements 23 of the transverse displacement module 2b. The spring forces of the second contact spring elements 26b are also perpendicular to the insertion direction. In 6B and 6C The locking projection 233 formed on the first conductor end 231a of the conductor element 23 and the locking recess 212 formed on the connection housing 21 can also be seen. The locking projection 233 is in this case designed as a locking hook. The locking recess 212 is in this case designed as an opening (locking opening) of the connection housing 21. The locking projection 233 is designed to lock into the locking recess 212, so that the conductor element 23 or the first conductor end 231a is prevented from slipping out of the connection housing 21 by the spring force of the contact spring element 26b when the DIN rail device module 1 is removed from the operating position.

The DIN rail device module 1 further comprises a first side surface 17a and first hook elements 18a, each of which is arranged on the first side (right side in 6A , 6B) of the DIN rail device module 1, wherein the first hook elements 18a each have a first end portion 181a which is spaced from the first side surface 17a. The feed module 2a has projection elements 28 in this embodiment. When the DIN rail device module 1 is in the operating position (as in 6A , 6B shown), the projection elements 28 of the feed module 2a are arranged between the first side surface 17a and the first end sections 181a of the first hook elements 18a and are actuated by means of the spring forces of the snap spring elements 25 (see 10 and corresponding description) and/or by means of the spring forces of the first contact spring elements 26a against the first end sections 181a of the first hook elements 18a. Furthermore, the DIN rail device module 1 has a second side surface 17b and second hook elements 18b, each of which is arranged on the second side (left side in 6A , 6B) of the DIN rail device module 1, wherein the second hook elements 18b each have a second end portion 181b which is spaced from the second side surface 17b. The transverse displacement module 2b has projection elements 28 in this embodiment. When the DIN rail device module 1 is in the operating position, the projection elements 28 of the transverse displacement module 2b are arranged between the second side surface 17b and the second end portions 181b of the second hook elements 18b and are prestressed against the second end portions 181b of the second hook elements 18b by means of the spring forces of the second contact spring elements 26b.

9 shows a cross-sectional view along DD in 2 . In this embodiment, the device carrier module 3 comprises three locking units for locking onto three parallel top-hat rails 7. The locking units each comprise a first locking element 38a; a second locking element 38b which is arranged to be movable back and forth relative to the first locking element 38a along the longitudinal direction between an arrangement position for arranging the device carrier module 3 relative to a top-hat rail 7 so that the top-hat rail 7 can be positioned between the first locking element 38a and the second locking element 38b, and a clamping position for clamping or clamping the top-hat rail 7 between the first locking element 38a and the second locking element 38b; and a locking spring element 39 which is configured such that it preloads the second locking element 38b in the direction of the first locking element 38a in each position. 9 shows in particular three locking units: in the central and right locking units, the second locking element 38b is in the arrangement position, while in the left locking unit the second locking element 38b is in the clamping position. The second locking element 38b further comprises an engagement element 381 into which a user can engage with a tool, e.g. a screwdriver, in order to move the second locking element 38b against the spring force of the locking spring element 39 from the clamping position to the arrangement position in order to release the device carrier module 3 or the mounting panel from the top hat rail 7.

10 shows a cross-sectional view along EE in 2 . In this embodiment, the respective right-hand connection module 2a comprises one or more snap projections 24, which are designed as snap hooks 24, and one or more snap spring elements 25, and the DIN rail device module 1 has one or more snap recesses 14 or undercuts 14. When the DIN rail device module 1 is in the operating position, as in 10 shown, grei The one or more snap projections 24 fit positively into the one or more snap recesses 14 and are pre-tensioned by spring forces of the one or more snap spring elements 25 in the direction of the DIN rail device module 1. In this embodiment, the spring forces are perpendicular to the insertion direction, ie parallel to the mounting panel (horizontal in 10 ).

In the following, the left device carrier module 3 (from 11A to 12C ) and the central device carrier module 3 (from 13A to 14C ) are described together, since they essentially only differ in the power supply block of the left device carrier module 3.

The device carrier module 3 comprises a first side wall 33a and a second side wall 33b, which are arranged on opposite sides (left side and right side in 12B or 14B) of the equipment carrier module 3 and are each arranged in the longitudinal direction of the equipment carrier module 3 (vertical direction in 12B or 14B) extend.

In this embodiment, the device carrier plug elements 351 are designed as plug recesses into which corresponding connecting plug elements 22 of a connecting module 2, which are designed as plug projections, can be inserted. In particular, the device carrier plug elements 351 are designed as plug recesses that are L-shaped. Thus, the connecting plug elements 22 of a connecting module 2, which are designed as plug projections, can be inserted into the respective L-shaped plug recesses 351 by an L-shaped movement. This L-shaped movement is in 13A , 13B , 14B and 23A each marked by dashed arrows. The connection module 2 is first inserted along the insertion direction (direction perpendicular to the paper plane in 14B) towards the device carrier module 3 so that the connecting plug elements 22 are inserted into the device carrier plug elements 351. The connecting module 2 is then moved along the longitudinal direction of the device carrier module 3. In this way, the connecting module 2 is fastened to the device carrier module 3. Two opposing connecting modules 2, which are plugged into a first slot 35a or second slot 35b, are moved away from each other in opposite directions along the longitudinal direction of the device carrier module 3. In order to release the two connecting modules 2 from the device carrier module 3 again, the connecting modules 2 must first be moved towards each other along the longitudinal direction and then moved away from the mounting panel along the insertion direction. However, if a DIN rail device module 1 is inserted in the operating position between the two connection modules 2 and is locked into place with the two connection modules 2, the connection modules 2 cannot be moved towards each other without first removing the DIN rail device module 1 from the operating position. This ensures that the connection modules 2 and the DIN rail device modules 1 are attached to the device carrier modules 3 in a particularly simple, stable and secure manner.

In this embodiment, the device carrier module 3 comprises four conductor insertion tracks 31, which extend in the longitudinal direction of the device carrier module 3 and are designed for inserting and/or detachably fastening four conductor rails 5, wherein two adjacent conductor insertion tracks 31 are separated from one another by an electrically insulating separating track 32. In this embodiment, in the left device carrier module 3 (shown in 11A to 12C ) a conductor rail 5 is inserted into each of the four conductor insertion tracks 31. The conductor insertion tracks 31 and conductor rails 5 are, however, protected by the electrically insulating cover gen 36 and therefore not visible; see, however, 22A and 22B .

In this embodiment, the device carrier module 3 further comprises six first transverse connecting elements 34a, which are attached to the first side wall 33a (left side wall in 12B or 14B) of the device carrier module 3, and six second cross-connecting elements 34b, which are arranged on the second side wall 33b (right side wall in 12B or 14B) of the device carrier module 3. The device carrier module 3 (e.g. the left device carrier module 3 in 2 ) and a first additional device carrier module 3 (e.g. the central device carrier module 3 in 2 ) can be detachably attached to one another via the second transverse connecting elements 34b of the device carrier module 3 and the first transverse connecting elements 34a of the first further device carrier module 3, so that the first further device carrier module 3 is arranged offset in the transverse direction relative to the device carrier module 3. In this embodiment, the first transverse connecting elements 34a are designed as projections and the second side connecting elements 34b are designed as depressions, wherein the projections 34a are T-shaped (see in particular 12B and 14B in which the T-shape is visible in the top view).

Furthermore, the device carrier module 3 in this embodiment comprises two first longitudinal connecting elements 37a, which are arranged at the lower edge portion in 12B or 14B of the device carrier module 3, and two second longitudinal connecting elements 37b, which are arranged on the upper edge section in 12B of the device carrier module 3, wherein the device carrier module 3 and a second further device carrier module 3 can be releasably fastened to one another via the second longitudinal connecting elements 37b of the device carrier module 3 and the first longitudinal connecting elements 37a of the second further device carrier module 3, so that the second further device carrier module 3 is arranged offset relative to the device carrier module 3 in the longitudinal direction of the device carrier module 3. The first longitudinal connecting elements 37a are in 11A to 14C covered by covers and therefore not visible; however, see 22A and 22B . In this embodiment, the first longitudinal connecting elements 37a are designed as fastening pins and the second longitudinal connecting elements 37b as fastening slots. The fastening pins and the fastening slots are arranged parallel to or along the separating tracks 32 of the device carrier module 3. When the device carrier module 3 and the second further device carrier module are fastened to one another, the fastening pins of the device carrier module 3 engage in the fastening slots of the second further device carrier module, as described below in connection with 28 and 29A to 29C described.

15A and 15B each show a perspective view of a device carrier module 3 with plugged-on output modules 2c; 16A shows a side view of the right side of the equipment carrier module; 16B shows a top view of the equipment carrier module; 16C shows a side view of the left side of the device carrier module; this device carrier module 3 corresponds to the right device carrier module 3 in 2 . The right device carrier module 3 from 15A to 16C differs from the central device carrier module 3 essentially only by the additional coding elements 361 on the lower cover 36, which have already been described in connection with 5A to 5C The coding elements 361 can, however, be arranged at any position on the covers 36 of the one or more device carrier modules 3. In 15A , 16B and 16C You can also see the neutral conductor rail 6, which is described in more detail below.

Thus, identical or essentially identically designed device carrier modules 3 can be used to attach the power feed block with the input terminals 8, the conductor rails 5 and the feed module 1a for the power input (as in the case of the left device carrier module 3 in 2 ), or to attach the neutral conductor rail 6 and the output module 1c for the current output to it (as in the case of the right device carrier module 3 in 2 ), or to simply attach connection modules 2b for the transverse displacement of the current on the mounting panel (as in the case of the central device carrier module 3 in 2 ). One and the same device carrier module 3 can thus be used (depending on the arrangement of this device carrier module 3 within the modular assembly panel system or depending on the combination of this device carrier module 3 with other modules) for the power feed, the transverse displacement of the current on the assembly panel or the power output. This enables a particularly efficient and cost-effective production of the device carrier modules and the electrical distributor.

17A shows a view from the bottom direction in 2 a connection module 2, more specifically a transverse displacement module 2b, which in 1A , 1B mounted on the left and central equipment carrier module. 17B shows a cross-sectional view along II in 17A . 17C shows a cross-sectional view along I1-I1 in 17A . 17D shows a perspective view of the connection module 2, 2b from 17A . 17E shows a perspective view of the conductor elements 23 of the connection module 2, 2b from 17A .

The transverse displacement module 2, 2b from 17A to 17E comprises four conductor elements 23, each with a first conductor end 231a and a second conductor end 231b, wherein the first conductor ends 231a and the second conductor ends 231b can each be contacted via a corresponding opening in the connection housing 21. The four conductor elements 23 correspond to the three outer conductors L1, L2, L3 and the neutral conductor N. Each conductor element 23 can thus electrically connect a first contact 13a (or second contact 13b) of a series-mounted device module 1 to a first contact 13a (or second contact 13b) of another series-mounted device module 1, wherein the two series-mounted device modules 1 are arranged in their respective operating positions in the same installation row. The connection module 2, 2b from 17 therefore conducts the current transversely along the installation row (in the transverse direction) and is therefore also referred to as transverse displacement module 2, 2b.

The openings of the connection housing 21, via which the first conductor ends 231a and the second conductor ends 231b of the conductor elements 23 can be contacted, are designed and dimensioned such that the first conductor ends 231a and the second conductor ends 231b cannot be contacted by a test finger in accordance with the standard DIN EN 60529. The connection housing 21 thus has an electrically insulating contact protection 211, by which the first conductor ends 231a and second conductor ends 231b are partially covered, as in 17A and 17D can be seen. In this embodiment, the contact protection 211 contains in particular an electrically insulating wall with sufficiently narrow openings for contacting the conductor ends 231a, 231b, so that a user cannot touch the contacts through the openings.

The conductor elements 23 of the connection module 2, 2b are also plate-shaped, as in 17E can be seen. The conductor elements 23 each have a connecting section 232 which connects the respective first conductor end 231a to the respective second conductor end 231b, wherein the connecting sections 232 of the plurality of conductor elements 23 extend in the transverse direction (horizontal direction in 17A) and are arranged offset from each other in the transverse direction. Furthermore, the connecting portions 232 of the plurality of conductor elements 23 are in the insertion direction (vertical direction in 17A and 17E) spaced apart from each other.

In 17B The contact spring elements 26 of the connection module 2, 2b are also shown, as described above. The connection module 2, 2b also comprises grooves 29 into which the guide elements 19 of the DIN rail device module 1 (see 27A and 27D to 27F) can engage (or edges 29 on which the guide elements 19 can rest) in order to move the DIN rail device module 1 relative to the connection module 2 along the insertion direction. Furthermore, the connection module 2, 2b comprises connection plug elements 22, which in this embodiment are designed as plug projections, as described above. Furthermore, in 17A and 17D the coding pins 27 can be seen.

18A shows a view from the upper direction in 2 a connection module 2, more specifically a transverse displacement module 2b, which in 1A , 1B mounted on the central and right equipment carrier modules. 18B shows a top view of the connection module 2, 2b from 18A . 18C shows a cross-sectional view along JJ in 18A . 18D shows a cross-sectional view along KK in 18A . 18E shows a perspective view of the connection module 2, 2b from 18A . 18F shows a perspective view of the conductor elements 23 of the connection module 2, 2b from 18A .

The transverse displacement module 2, 2b from 18A to 18F has similar features to the transverse displacement module 2, 2b from 17A to 17E However, the transverse displacement module 2, 2b comprises 18A to 18F three conductor elements 23, each with a first conductor end 231a, a second conductor end 231b and a third conductor end 231c, wherein the first conductor ends 231a, the second conductor ends 231b and the third conductor ends 231c can each be contacted via a corresponding opening in the connection housing 21. These three conductor elements 23 correspond to the three outer conductors L1, L2, L3. Each of these three conductor elements 23 can electrically connect a first contact 13a (or second contact 13b) of a series-mounted device module 1 to a first contact 13a (or second contact 13b) of another series-mounted device module 1 and to a first contact 13a (or second contact 13b) of a still further series-mounted device module 1, wherein the three series-mounted device modules are in their respective operating positions in the same installation row. The connection module 2, 2b from 17 therefore also conducts the current across the installation row. In addition, the transverse displacement module 2, 2b contains 18A to 18F another conductor element 23 (fourth conductor element 23 from the right in 18A , 18B , 18E and 18F) , the second conductor end 231b of which can be connected to the neutral conductor rail 6 via a fastening element 52, as further below in connection with 22A to 23D described.

In 18C the contact spring element 26 of the connection module 2, 2b is also shown, as described above. In 18D the snap projection 24 and the snap spring element 25 are also shown. When a DIN rail device module 1 is in the operating position, a snap projection 24 engages in a corresponding snap recess 14 of the DIN rail device module 1 and is preloaded in the direction of the DIN rail device module 1 by means of a spring force of the snap spring element 25. The snap projection 24 further comprises an engagement element 241 into which a user can engage with a tool, e.g. a screwdriver, in order to move the snap projection 24 in the opposite direction (away from the DIN rail device module 1) against the spring force of the snap spring element 25. In this way, the locking between the DIN rail device module 1 and the connection module 2 can be released, and the DIN rail device module 1 can then be removed from the operating position and moved away from the mounting panel along the insertion direction. In this embodiment, in particular the connection modules 2, which are plugged into first slots 35a, have snap projections 24 and snap spring elements 25 (see 10 ).

19A shows a view from the bottom direction of a connection module 2, more specifically an output module 2c, which is in 1A , 1B mounted on the right equipment carrier module 3. 19B shows a cross-sectional view along LL in 19A . 19C shows a top view of the connection module from 19A . 19E shows a perspective view of the connection module from 19A .

In this embodiment, the output module 2, 2c comprises six conductor elements 23, each with a first conductor end 231a and a second conductor end 231b. The first conductor ends 231a can each contact a contact 13 of a DIN rail device module 1 (see in particular 19B) . The second conductor ends 231b are each configured to connect a consumer device, e.g. via a respective output terminal 9 (see 19C ). Furthermore, the output module 2, 2c comprises six output conductor elements 23' (not fully shown), each having a first output conductor end 231a' and a second output conductor end 231b'. The first output conductor ends 231a' can each contact the neutral conductor rail 6, which is arranged at least partially within the output module 2c, as shown in 19A to 19D can be seen. The second output conductor ends 231b' are each configured for connecting a consumer device, e.g. via a respective output terminal 9 (see 19C ). Each consumer device can thus be connected both to the second conductor end 231b of a conductor element 23 (corresponding to an outer conductor L1, L2, L3) and to the second output conductor end 231b' of an output conductor element 23' (corresponding to the neutral conductor N) in order to close the circuit between the distributor and the consumer device. In this embodiment, for example, six single-pole or two three-pole consumer devices can be connected to the output module 2c. The other properties of the output module 2, 2c are similar to those of the transverse displacement module 2, 2b as described above.

20A shows a cross-sectional view along FF in 2 . 20B shows the enlarged section K from 20A . 20C shows the enlarged section J from 20A . In 20A and 20B In particular, a connection module 2 can be seen, which is plugged into a second slot 35b of a device carrier module 3. The connection plug elements 22 of the connection module 2, which are designed as plug projections, are plugged into the device carrier plug elements 351 of the device carrier module 3, which are designed as plug recesses. In 20A and 20C It can also be seen how two adjacent equipment carrier modules 3 are fastened to one another via the corresponding cross-connecting elements 34a, 34b.

21A shows a cross-sectional view along GG in 2 . 21B shows the enlarged section M from 21A . In these figures, a connection module 2 can be seen in particular, which is plugged into a first slot 35a of a device carrier module 3. The connection plug elements 22 of the connection module 2, which are designed as plug projections, are plugged into the device carrier plug elements 351 of the device carrier module 3, which are designed as plug recesses.

22A shows a perspective view of the modular mounting panel system with inserted conductor rails 5 and with neutral conductor rails 6, whereby the covers 36 of the device carrier modules 3 have been removed. 22B shows a top view of the modular mounting panel system from 22A . In these figures, the following can be seen in particular: the four parallel conductor insertion tracks 31 of the left and the middle device carrier module 3 and the separating tracks 32 arranged between them; the six parallel conductor insertion tracks 31 of the right device carrier module 3 and the separating tracks 32 arranged between them; the four conductor insertion tracks 31 of the left four conductor rails 5 inserted into the device carrier module 3; the associated four clamping screws 8 for the power supply to the conductor rails 5; the associated four conductor elements 23 per installation row, the second conductor ends 231b of which contact the conductor rails 5 and which can be inserted into the connection housing 21 of the feed-in module 2, 2a when the feed-in module 2, 2a is plugged onto the left device carrier module 3, so that the respective first conductor ends 231a can contact corresponding contacts 13 of the series-mounted devices 1 through corresponding openings in the feed-in module 2, 2a; the device carrier plug-in elements 351, which are arranged in or on the isolating strips 32; the neutral conductor rails 6, which are contacted by corresponding conductor elements 23 of the connection modules 2, 2b (see 18A to 18F , as well as the following 23A to 23D ); the first side walls 33a and the second side walls 33b of the device carrier modules 3, whereby two adjacent side walls 33a, 33b of two device carrier modules 3 fastened to one another form an electrically insulating separating strip 32; the first longitudinal connecting elements 37a (designed as fastening pins or pin elements) and the second longitudinal connecting elements 37b (designed as fastening slots or openings) of the device carrier modules 3; and marked with dashed arrows are the L-shaped and mutually opposing plugging movements of two connection modules 2, which are each plugged into a first slot 35a and a second slot 35b. In 22B It can also be seen that the center lines of two adjacent conductor insertion tracks of the left device carrier module are spaced apart by d1, the center lines of two adjacent conductor insertion tracks of the central device carrier module are also spaced apart by d1, and the center lines of two adjacent conductor insertion tracks of the right device carrier module are spaced apart by d2. For example, d1 = 27 mm and d2 = 18 mm, as described above.

In 23A to 23D For the upper installation row, the neutral conductor rail 6 can be seen in particular. The neutral conductor rail 6 is arranged at least partially within the corresponding output module 2, 2c, which is plugged into a second slot 35b of the right device carrier module 3. The neutral conductor rail 6 is also connected via a fastening element 52 to a second conductor end 231b of a conductor element 23 of a connection module 2, 2b, which is plugged into the opposite first slot 35a.

24A shows an embodiment of a conductor rail 5 and conductor elements 23 attached thereto. 24B shows the enlarged section W from 24A . The conductor rail 5 is plate-shaped or strip-shaped. The conductor elements 23 each have a first conductor end 231a and a second conductor end 231b and are each fastened to the conductor rail 5, in particular to the notch 51 of the conductor rail 5, by means of a fastening element 52 in such a way that the second conductor end 231b contacts the conductor rail 5 and the conductor element 23 is arranged so as to be rotatable relative to the conductor rail 5 about the second conductor end 231b. If no external force acts on the conductor element 23, the conductor element 23 is perpendicular to the corresponding conductor rail 5, as in 24A , B. When a feed-in module 2, 2a is plugged onto the device carrier module 3, the conductor elements 23 can be inserted into the connection housing 21 of the feed-in module 2, 2a, so that the first conductor ends 231a of the conductor elements 23 can be contacted through corresponding openings in the connection housing 21. Since the conductor elements 23 are arranged so as to be rotatable about the second conductor ends 231b relative to the corresponding conductor rails 5, in this case the first conductor ends 231a can be pre-tensioned against the contacts 13 of a DIN rail device module 1 by means of the spring forces of the contact spring elements 16, 26. The conductor elements 23 can alternatively be designed in terms of their position and orientation direction of the conductor ends 231b on the conductor rail 5 so that a feed of the DIN rail device module 1 (shown in 24A) from below as well as from above. In particular, identically designed conductor rails 5 can be used for both the embodiment in 1A , 1B (power supply from above) as well as for the version in 30 (power supply from below) can be used; for the embodiment in 30 The conductor rails 5 only have to be installed the other way round (compared to the embodiment in 1A , 1B) be inserted into the conductor insertion tracks 31. It should be noted that in alternative embodiments the output terminals 9 can also be arranged in the opposite direction (ie on the first side of the DIN rail device modules 1 instead of on the second side of the DIN rail device modules 1 or on the lower side of the device carrier modules 3 instead of on the upper side of the device carrier modules 3). The arrangement (top or bottom) of the input terminals 8 can be adapted to the arrangement (top or bottom) of the output terminals 9 and/or to the number of device carrier modules 3 in the transverse direction in order to achieve the desired switching arrangement of the distributor. Since the conductor rails 5 do not have to be exchanged for this purpose, but only have to be inserted into the conductor insertion tracks 31 in the corresponding orientation, the flexibility and user-friendliness are further increased.

25A shows an embodiment of a conductor rail 5 and conductor elements 23 attached thereto. 25B shows the enlarged section V from 25A . The conductor rail 5 from 25A and 25B has a greater thickness than the conductor rail 5 from 24A and 24B . The conductor elements 23 in 25A and 25B However, they are identical to the conductor elements 23 in 24A and 24B trained.

26A-C show three different embodiments of the conductor rail 5. The conductor rails 5 each have a fastening section 53 for fastening the conductor rail 5 to a corresponding conductor insertion track 31 of the device carrier module 3 and a contact section 54 for contacting the second conductor end 231b of a corresponding conductor element 23. The contact section 54 has in particular the notches 51 to which the second conductor ends 231b of the conductor elements 23 can be fastened. The three conductor rails 5 in 26A-C have different thicknesses, whereby the conductor rail 5 in 26A the smallest thickness and the conductor rail 5 in 26C has the greatest thickness. Nevertheless, the three conductor rails 5 can be used with identical device carrier modules 3 and with identical conductor elements 23, because for each conductor rail 5, a bottom side of the fastening section 53, with which the respective conductor rail 5 is fastened to the conductor insertion track 31, and a top side of the contact section 54, to which the corresponding conductor element 23 is fastened, have the same predetermined distance from each other. In the case of the conductor rail 5 in 26C this predetermined distance is equal to the thickness of the conductor rail 5.

27A shows a perspective view of a DIN rail mounted device module 1, more specifically of a fuse switching device module 1a. 27B shows a top view of the DIN rail device module 1 from 27A . 27C shows a cross-sectional view along RR in 27B . In this embodiment, the series-mounted device module 1, 1a has four first contacts 13a and four second contacts 13b, each of which is designed to contact the neutral conductor N and the three external conductors L1, L2, L3. In particular, the first contacts 13a and the second contacts 13b are plate-shaped. Furthermore, the series-mounted device module 1 comprises guide elements 19 for engaging in grooves 29 or for resting on edges 29 of a connection module 2 and for moving the series-mounted device module 1 relative to the connection module 2 along the insertion direction. In 27A the first coding slots 15a, which are arranged on the first side of the DIN rail device module 1, and the second coding slots 15b, which are arranged on the second side of the DIN rail device module 1, can also be seen. When the DIN rail device module 1 is in the operating position, the coding slots 15a, 15b extend along the insertion direction. The first coding slots 15a and the second coding slots 15b of the fuse switching device module 1, 1a are arranged in a diagonal direction relative to one another, so that the fuse switching device module 1, 1a can only be fitted onto the left device carrier module 3 in 5C can be plugged on, but not on the central device carrier module 3 or the right device carrier module 3.

27D shows a perspective view of a DIN rail mounted device module 1, more specifically of an RCD module 1b. 27E shows a perspective view of a DIN rail mounted device module 1, more specifically of a circuit breaker protection device module 1c. 27F shows a perspective view of another DIN rail device module 1d. The DIN rail device modules 1b, 1c, 1d from 27D to 27E have similar features to the fuse switchgear module 1a from 27A to 27C However, the circuit breaker module 1c in this embodiment has only one first contact 13a and one second contact 13b, each for contacting one of the three external conductors L1, L2, L3 (i.e. it is a single-pole series-mounted device module 1c), and the further series-mounted device module 1d has three first contacts 13a and three second contacts 13b for contacting the three external conductors L1, L2, L3 (i.e. it is a three-pole series-mounted device module 1d). The first coding slots 15a and the second coding slots 15b of the residual current device module 1b are arranged relative to one another in the longitudinal direction, so that the residual current device module 1b can only be connected to the central device carrier module 3 in 5C can be plugged on, but not on the left device carrier module 3 or the right device carrier module 3. The first coding slots 15a and the second coding slots 15b of the LS protection device module 1c and the further DIN rail mounted device module 1d are arranged relative to each other in an opposite diagonal direction, so that the LS protection device module 1c and the further DIN rail mounted device module 1d can only be plugged on the right device carrier module 3 in 5C can be plugged in, but not on the left device carrier module 3 or the middle device carrier module 3. In 27F Furthermore, rectangular recesses in the DIN rail device module 1d can be seen, into which the coding elements 361 positively engage when the DIN rail device module 1d is in the operating position in order to prevent incorrect insertion of the DIN rail device modules 1, as described above.

28 shows a perspective view of an embodiment of a modular series construction equipment system and an embodiment of a modular assembly panel system. 29A shows a top view of the modular DIN rail device system and the modular mounting panel system from 28 . 29B shows a cross-sectional view along OO in 29A . 29C shows the enlarged section P from 29B .

In this embodiment, two device carrier modules 3 are fastened to one another in the longitudinal direction via the corresponding longitudinal connecting elements 37a, 37b. In particular, the 29A Device carrier module 3 located at the top left and the 29A The further device carrier module 3 arranged at the bottom left is fastened to one another in the longitudinal direction in such a way that the conductor insertion tracks 31 of the device carrier module 3 are extended or continued in the longitudinal direction by the conductor insertion tracks 31 of the further device carrier module 3. Thus, the conductor rails 5 arranged in the conductor insertion tracks 31 of the device carrier module 3 and the conductor rails 5 arranged in the conductor insertion tracks 31 of the further device carrier module 3 can be fastened to one another and brought into contact in order to obtain conductor rails 5 extended in the longitudinal direction. Thus, only a power supply via the clamping screws 8 of the 29A The device carrier module 3 located at the top left is required, while the clamping screws 8 of the 29A The two terminals of the device carrier module 3 arranged at the bottom left serve to fasten and/or connect the conductor rails 5 in the device carrier module 3 with the conductor rails 5 in the further device carrier module 3. This embodiment of the mounting panel system can also be fastened to six parallel top hat rails 7. Note that one and the same connection of a device carrier module 3 or one and the same clamping screws 8 can thus be used for the power supply (as in the case of the device carrier module 3 shown in 29A device carrier module 3 located at the top left) or for connecting another device carrier module 3 (as in the 29A device carrier module 3) located at the bottom left. This allows for individual and flexible installation, increasing user-friendliness depending on the desired application.

30 shows a perspective view of an embodiment of a modular DIN rail device system and an embodiment of a modular mounting panel system. In this embodiment, the power is fed to the conductor rails 5 by a power feed block which is attached to a lower section of the left device carrier module 3 (in 30 bottom left), i.e. at an opposite section compared to the embodiment described above (cf. 1A , 1B) .

31A shows a cross-sectional view of an embodiment of a modular DIN rail device system and an embodiment of a modular mounting panel system. 31B shows the enlarged section Q from 31A . In this embodiment, the DIN rail device module 1 (instead of the connection module 2 in the 6A and 6B embodiment shown) first contact spring elements 16a which are configured such that when the DIN rail device module 1 is in the operating position (as in 31A , 31B shown), the first contacts 13a of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the 31B right connection module 2, 2a are prestressed against each other by means of spring forces of the first contact spring elements 16a. In this embodiment, the first contact spring elements 16a are attached on the one hand to the DIN rail device housing 11 and on the other hand to the first contacts 13a of the DIN rail device module 1. The spring forces of the first contact spring elements 16a are perpendicular to the insertion direction (ie they run horizontally in 31A , B). The same applies to the second contact spring elements 16b and the second contacts 13b of the DIN rail device module 1 as well as the 31B left connection module 2, 2b.

32 shows a cross-sectional view of an embodiment of a modular DIN rail device system. In this embodiment, the DIN rail device module 1 comprises the contact spring elements 16, and the spring forces of the contact spring elements 16 are perpendicular to the insertion direction (ie they run horizontally in 32 ).
