Description

electronic components

technical field

The invention relates to an electronic assembly with a plurality of electronic modules arranged side by side, wherein each electronic module has a base housing, at least two conductor connection elements, an electronic plug which can be plugged onto the base housing from a first side. The components, in particular the relay, and the holding and ejecting bracket for the electronic components are arranged pivotably on the base housing.

Background technique

Electronic modules and electronic devices for placement on carrier rails have been known for many years and are used in different embodiments and for different applications. Similar to electrical series terminals, which are generally also locked on the carrier rail, the electronics module in question has at least two conductor connection elements, wherein, apart from screw terminals or tension spring terminals, as conductor connection elements since several years Since then, helical torsion spring terminals have also been increasingly used. Helical torsion spring terminals are often also referred to as direct connection terminals, because they enable the direct connection of rigid or conductors provided with core wire end sleeves, without the clamping position (for example in the case of tension spring terminals) having to be fixed. Open in advance.

In contrast to conventional electrical series terminals which are designed as feed-through terminals, the electronics module in question additionally has electronic components which are designed to be pluggable so that they can be plugged onto the basic housing of the electronics module, which then serves as a connection base. The pluggable electronic component can in particular be a relay, so that the basic housing of the electronics module is a relay base. Depending on the type of electronic component used, the electronic module can be used for various applications, for example as a coupling relay between the control unit and the individual field devices, as a relay for signal frequency multiplication or as a power relay.

It was stated at the outset that the invention relates to an electronic assembly with a plurality of electronic modules arranged side by side. In this case, the individual electronic modules which together form the electronic assembly are generally arranged side by side on the carrier rail. The number of electronic modules arranged next to each other and together forming an electronic assembly can in principle be freely selected, wherein the individual electronic modules can have the same type of electronic components or also different electronic components depending on the application. An electronic assembly with electronic modules arranged side by side is known from DE 10 2012 015 037 A1. A relay is correspondingly plugged onto the base housing of the electronics module, which relay can be electrically connected via conductor connection elements arranged in the corresponding base housing.

In order to fix the relays in the base housing, each electronics module has a relay holding bracket which is pivotably mounted on the base housing. In this case, the relay holding bracket is designed by means of tabs or projections which abut the plugged-in relay, so that the plugged-in relay can be detached from the basic housing by pivoting the relay holding bracket. The relay can then be easily and effortlessly removed and replaced by hand. The relay holding bracket therefore additionally has an ejection or release function in addition to its holding or fixing function, so that it can accordingly also be referred to as a holding and ejecting bracket.

Furthermore, the respective electronic modules also have plug-in modules, which can be, for example, timing modules, whereby the relay modules can be expanded into timing relays. In this case, the plug-in modules accordingly have a width that is smaller than the base housing and the U-shaped relay holder, so that the relay holder is in the case of a plug-in module that is plugged onto the base housing (overlapping plug-in modules) Can also be swung.

In general, DE 10 2012 015 037 A1 already discloses an electronic module or an electronic assembly composed of a plurality of electronic modules, which can be used very variedly, in particular due to the exchangeability of the individual relays, wherein Replacement of damaged relays is also simple and therefore user-friendly. Furthermore, the connection elements of adjacent electronics modules can be bridged to one another via the bridging ports formed in the basic housing, whereby the wiring costs can be reduced in the case of a plurality of electronics modules arranged next to each other.

Contents of the invention

Starting from the electronic modules or electronic components known from this document, the invention is based on the object of further facilitating the handling and assembly of the electronic components for the user.

This object is achieved in the case of the electronic assembly described at the outset with the features of patent claim 1 in that an adapter module is provided which has an adapter housing, a number of plug sockets corresponding to the number of electronic modules Contact points and at least one interface for connecting cables. The individual electronics modules have mating contacts corresponding to the plug contacts, which are accessible from the first side, so that the adapter modules, like the individual electronic components, can be plugged onto the base housing from the first side. Thus, an electronic assembly composed of a plurality of electronic modules arranged next to one another has a common adapter module which extends over the entire width of the electronic assembly, wherein all electronic modules are plugged in via the adapter module via the respective plugs formed on the adapter module. The contact points are contacted with corresponding mating contacts formed in the electronics module. Preferably, the adapter module here has two plug contacts per electronic module and each electronic module correspondingly has two mating contacts, wherein the plug contacts can be configured as contact sockets or contact pins and the mating contacts Can be configured as a contact socket.

According to the invention, the adapter module has at least one interface for connecting a cable, wherein the interface is preferably a plug or a socket, so that a cable with a corresponding socket or a corresponding plug can easily be connected electrically and mechanically to the interface place. This interface can be, for example, a communication interface via which the individual electronic modules contacted via the adapter module can be easily configured and operated.

According to the invention, the adapter module also has at least one pivotably mounted ejection lever, which can be pivoted from the first position into the second position. In this case, the ejection lever cooperates with the first side of the basic housing of an electronics module or of the basic housings of two adjacent electronics modules facing the adapter module in such a way that the adapter module is removed from the electronics module by actuating the ejection lever. The basic housing of the machine is raised or removed. In the first position of the ejection lever, the adapter module is completely plugged onto the electronics module and the individual plug contacts make contact with associated mating contacts of the electronics module. In the second position of the ejection lever, the plug-in connection between the adapter module and the electronic module is released to such an extent that a basic side-by-side arrangement of the adapter module from the electronic assembly or from the individual electronic modules can be easily achieved. Pull out of the case. Preferably, the electrical contact between the respective plug contact and the mating contact is separated here. The removal of the pluggable adapter module from the electronic assembly is facilitated by the adapter module having at least one ejection lever, wherein the adapter module is still mechanically connected to the base housing, so that the adapter module cannot be unintentionally dropped .

When the electronic assembly according to the invention has only a relatively small number of electronic modules arranged side by side, for example four electronic modules, it is possible when an adapter module which is the width of four electronic modules arranged side by side has only one ejection lever Will suffice. The ejection lever is then preferably arranged centrally between the plug contacts associated with the two central electronics modules, in order to make the basic housing of the adapter module and the electronics module as free as possible and only relatively relatively Untie with little power consumption is possible.

Especially when the electronic assembly however has a relatively large number of electronic modules arranged side by side, for example six or eight electronic modules arranged side by side, the adapter module then preferably has two ejection levers, which are then correspondingly arranged on the associated side of the adapter module. in the vicinity of the plug contacts of the external electronics module. In the case of an electronic assembly with a total of eight electronic modules arranged side by side, one of the ejection levers can be arranged, for example, between the plug contacts associated with the first electronic module and with the second electronic module, and the second ejection lever The rod is arranged between the plug contacts associated with the seventh electronic module and with the eighth electronic module. The arrangement of the two ejection levers reduces the risk of skewing during uncoupling of the adapter module from the electronic assembly, which on the one hand makes it difficult to remove the adapter module and on the other hand can lead to individual plug contacts Or damage to each mating contact.

Regardless of whether the adapter module has only one or two (or likewise several) ejection levers, each ejection lever thus preferably has an actuating arm and a lever arm arranged at an angle α to one another. In this case, the free end of the actuating arm is formed as an actuating section and the free end of the lever arm is formed as a bearing section by means of which the ejector lever is pivotably mounted in the adapter housing. In this case, the actuation section can have such a shape and size that it can be easily and comfortably actuated with fingers. In this case, the ejection lever can be swiveled from its first position into its second position by exerting a force towards the actuating section about an axis of rotation formed in the adapter housing. Preferably, the angle α between the actuating arm and the lever arm is approximately 70°-110°, in particular approximately 80°-100°, so that the actuating arm and the lever arm are arranged approximately perpendicular to each other.

A printed circuit board is preferably arranged in the adapter module, on which different electronic components can be arranged depending on the application. In principle, the same electronic components can correspondingly be provided in the adapter modules for all associated electronics modules. Furthermore, however, the possibility also exists that different electronic components are associated with different electronic components. For example, different time modules associated with the individual electronic modules can be arranged in the adapter module. The components assigned to the respective electronics module are electrically connected to the electronics module via plug contacts of the adapter module assigned to the electronics module and mating contacts arranged in the electronics module. For the individual actuation of the individual electronic components, it is therefore only necessary to connect the corresponding cables to the interfaces of the common adapter module.

Furthermore, the adapter module preferably also has a power supply port. In order to connect the electrical lines to the power supply port, different types of conductor connection elements can be used here. Via this power supply port, not only the adapter module but also the electronic components plugged into the individual electronic modules can be supplied with the necessary voltage. In practice, the individual basic housings with plugged-in electronics modules are often fastened on carrier rails in switch boxes or at other locations where the connection of electrical lines is relatively difficult due to the cramped positional conditions. Here, in the case of the electronic assembly according to the invention, there is the possibility that the cable is already connected to the interface or the wire to the power supply port before the adapter module is plugged onto the basic housing, so that for simple and rapid connection of the individual The electronics modules that are plugged into the base housing only have to be plugged in as well as the adapter modules.

According to a preferred embodiment of the electronic module according to the invention, each holding and ejecting bracket of the electronic module has two longitudinal legs and a transverse leg connecting the longitudinal legs, so that the holding and ejecting bracket has approximately U-shaped structure. In this case, the retaining and ejecting brackets are pivotably supported on the respective base housing with longitudinal legs, while the transverse legs are arranged above the top side of the electronic component in the secured state. Such a U-shaped holding and ejecting bracket is basically known, for example from DE 10 2012 015 037 A1.

In the case of the electronic assembly according to the invention, recesses are formed in the adapter module which are arranged corresponding to the longitudinal legs of the holding and ejecting bracket, so that when the holding and ejecting bracket is swung into its ejected position, Allows the longitudinal legs to be partially engaged in the void. The configuration of the recess in the adapter module makes it possible that when the adapter module is plugged onto the base housing adjacent to the electronics module in the longitudinal direction of the base housing, the retaining and ejecting bracket can then also be swiveled into its in the popup location. Due to the formation of the recess in the adapter module, handling of the respective holding and ejection brackets is therefore also not affected in the case of an adapter module that is plugged onto the electronics module from the same side in the vicinity of the opposite electronics component.

In order to be able to simultaneously pivot the two holding and ejecting brackets of two electronics modules arranged next to each other into their ejected positions, the width of the recess is preferably at least twice as large as the thickness of the longitudinal legs of the holding and ejecting brackets. As a result, two longitudinal legs of two adjacent holding and ejecting brackets can be swiveled into the recess at the same time.

According to a further advantageous embodiment of the electronic module according to the invention, the adapter module has a number of fastening lugs corresponding to the number of electronic modules, for which corresponding fastening recesses are formed in the basic housing of the electronic module. Here, the fastening tabs and the corresponding fastening grooves serve to improve the mechanical fastening of the adapter module on the basic housing, even when the plug contacts (for example as contact strips) and corresponding mating contacts are formed In addition to the electrical connection, a mechanical fastening between the adapter module and the electronics module can also be achieved.

In order to ensure that no unintentional detachment or release of the adapter module and the electronics module occurs even in the event of vibrations or vibrations, it is furthermore preferred to form a snap-in connection between at least one fastening tab and at least one fastening groove. . With the secure and permanent mechanical connection ensured by the snap connection, the reliability of the electrical connection between the respective plug contact and the respective mating contact is also increased at the same time.

If the adapter module has two ejection levers arranged in the vicinity of the outer plug contacts, it is advantageously provided that a snap connection is formed correspondingly only between the outer fastening tab and the corresponding fastening groove, while the rest There is no snap-in connection between the fastening tabs arranged therebetween and the remaining fastening grooves. In the case of an electronic assembly with, for example, eight electronic modules arranged side by side, then not eight but only two snap connections are realized, ie only two outer fastening tabs with two outer electronic modules. between the fixing grooves in the module. The configuration of the latching connection only with the outer fastening lugs ensures a sufficiently secure locking between the adapter module and the electronic component without the force necessary to release the latching connection by means of the ejection lever not being too high.

The above-described snap-in connection between the adapter module and the electronics component or electronics module can be realized particularly easily in that at least one snap-in hook is correspondingly formed in a fastening recess in the basic housing. Therefore, the fastening recesses in the individual basic housings arranged next to each other are identically configured. In contrast, at least one detent lug corresponding to the detent hook is arranged only at certain, preferably two outer fastening webs of the adapter module. By having the fastening recesses in the base housing correspondingly have at least one, preferably two snap hooks facing each other, the user does not have to pay attention to where the individual electronic modules are arranged in the electronic assembly in order to achieve Locking with adapter module. By forming the detent lugs corresponding to the detent hooks only on certain, preferably two outer fastening tabs, a detent connection is achieved only between these fastening tabs and the associated fastening recess. Since the remaining fastening lugs do not have detent lugs, no detent connection is achieved between these fastening lugs and the associated fastening groove, even if the associated fastening groove has at least one detent hook accordingly. .

It has been explained beforehand that the plug-in connection between the adapter module and the electronics module is released in the second position of the ejection lever to such an extent that the adapter module is essentially released from the electronics assembly or from the side-by-side arrangement of the individual electronics modules. The housing can be pulled out easily, wherein the adapter module is still mechanically connected to the base housing, so that the adapter module cannot be dropped unintentionally. For this purpose, the ejection lever and the snap connection formed between the fastening tab and the fastening groove are preferably coordinated with each other in such a way that the ejection lever is connected to the basic housing of an electronics module or to two adjacent electronics modules The first side of the basic housing facing the adapter module works together, that is, the snap connection between the adapter module and at least one electronic module is released in the second position of the ejection lever, the adapter module is however still connected to at least one electronic module. An electronic module is connected. The mechanical connection between the adapter module and the electronics module can be achieved in that the fastening lugs of the adapter module are also partially inserted into the corresponding fastening grooves in the case of a released snap connection. By releasing the snap connection, the adapter module can easily be pulled out of the base housing when the ejection lever is swiveled into the second position.

According to a further advantageous embodiment of the invention, the adapter module has a plurality of display elements, in particular a plurality of LEDs, wherein a display element is assigned to each electronics module. The adapter module thus has at least one display element whose number corresponds to the number of electronics modules. In this case, the display elements associated with the individual electronic modules are preferably used to indicate whether a defined voltage is present at the corresponding plug contact.

In order for the user to quickly and easily recognize the state of the individual display elements even when the respective retention and ejection bracket is swiveled into its ejection position, openings or windows are preferably formed in the transverse legs of the respective retention and ejection bracket. This ensures that individual display elements can then also be reliably identified when the respective holding and ejection bracket is in its ejected position in which the transverse leg covers the display element.

detailed description

FIG. 1 shows a perspective illustration of an electronic assembly 1 according to the invention, which has eight electronic modules 2 arranged next to each other, wherein each electronic module 2 has correspondingly a plurality of conductor connection elements 4 arranged therein. The basic shell 3. In the longitudinal direction L of the respective electronics module 2 , for example in the middle region of the respective electronics module 2 , the relay 5 is accordingly plugged as an electronic component from the first side (top side 3 a ) onto the basic housing 3 . In the exemplary embodiment shown, the individual relays 5 here accordingly have the same dimensions as can be seen in particular from FIGS. 1 and 2 . Regardless of this, however, different relays with different dimensions, in particular with different heights, can also be plugged onto the basic housing 3 .

Retaining and ejecting brackets 6 are correspondingly pivotably mounted at the respective basic housings 3 , with which the respective relays 5 are fixed in the first position of the retaining and ejecting brackets 6 ( FIG. 3 a ). In and from the respective basic housing 3 is detachable in the second position ( FIG. 3 b ) of the retaining and ejecting bracket 6 . In the second position, the holding and ejecting bracket 6 is swiveled to one side in such a way that the associated relay 5 can be easily pulled upwards from the basic housing 3 .

In addition to the eight electronics modules 2 , the electronics assembly 1 also has a common adapter module 7 , which is plugged onto eight electronics modules 2 or base housings 3 arranged side by side. The adapter module 7 shown separately in FIGS. 5 and 6 has an adapter housing 8 and a number of plug contacts 9 and interfaces 10 corresponding to the number of electronics modules 2 . In this case, the width of the adapter module 7 corresponds to the width of the electronics module 1 , so that the adapter module 7 is provided for a predetermined number of electronics modules 2 .

It can be seen from FIG. 6 that the plug contacts 9 are arranged in pairs, wherein every two plug contacts 9 designed as contact cards are associated with the electronics module 2 . Corresponding to the plug contacts 9 , each electronic module 2 has correspondingly two corresponding mating contacts 11 , which are accessible from the top side 3 a of the basic housing 3 , so that the adapter module 7 is accessible from the same direction as the respective relay 5 . Plugged into the electronic modules 2 arranged side by side. The mating contacts 11 can be configured, for example, as tulip contacts or contact sockets. Via the interface 10 , the individual relays 5 of the individual electronics modules 2 in the case of a plugged-in adapter module 7 can be easily actuated without each relay 5 having to be individually electrically connected via the electronics module 2 for this purpose. The connection 10 is designed as a socket, so that a cable and a corresponding plug can be electrically and mechanically connected to the connection in a simple and quick manner.

Furthermore, the adapter module 7 has two ejection levers 12 , which are respectively arranged in the vicinity of the outer plug contacts 9 . In this case, the ejection lever 12 is arranged in the adapter housing 8 such that in the plugged-in state of the adapter module 7 the ejection lever 12 is in each case centrally located between the two electronics modules 2 . As can be seen from the two illustrations according to FIG. 4 , the ejection lever 12 has an actuating arm 13 and a lever arm 14 which are arranged at an angle α to one another, which in the illustrated exemplary embodiment is approximately 90°. In this case, the free end of the actuating arm 13 is designed as an actuating section 15 , which has an enlarged area compared to the cross-section of the actuating arm 13 , so that the ejection lever 12 can be easily passed by the user with a finger towards the top of the actuating section 15 . The side press is pivoted from its first position ( FIG. 4 a ) into its second position ( FIG. 4 b ). The free end of the lever arm 14 is formed as a bearing section 16 which surrounds a bearing journal 17 formed in the adapter housing 8 .

If the ejection lever 12 is swiveled from the first position shown in FIG. 4 a , in which the adapter module 7 is completely plugged onto the respective electronics module 2 or the respective basic housing 3 , into the second position shown in FIG. 4 b , the lever arm 14 interacts with the top sides 3 a of two adjacent basic housings 3 in such a way that the adapter module 7 is removed from the basic housing 3 . In this case, the adapter module 7 is removed from the base housing 3 to such an extent that the snap connection formed between the adapter housing 8 and the base housing 3 is released, so that the adapter module 7 can be easily Unplugged by the user. However, the adapter module 7 is also mechanically connected to the base housing 3 so that it cannot fall out of the electronics assembly unintentionally.

In FIG. 3 the electronic assembly 1 is shown from the side, wherein the holding and ejecting bracket 6 is shown in FIG. 3 a in its holding position securing the associated relay 5 and in FIG. 3 b with the relay 5 removed from the housing Body 3 is shown in the ejected position with removal. As can be seen from FIG. 1 , each holding and ejecting bracket 6 is approximately U-shaped, wherein each holding and ejecting bracket 6 has two longitudinal legs 18 and connects the two longitudinal legs 18. The transverse outrigger 19 of. In order to be able to pivot the respective holding and ejecting bracket 6 into its second position even with a plugged-in adapter module 7, the adapter module 7 has a corresponding number of recesses 20 when the holding and ejecting bracket 6 is swiveled into In the second position, that is to say in the ejected position according to FIG. 3 b , the longitudinal leg 18 partially engages in the recess.

In this case, the width of the respective recess 20 is at least twice as large as the thickness of the longitudinal leg 18 of the retaining and ejecting bracket 6 . As a result, holding and ejecting brackets 6 arranged side by side can also be swiveled simultaneously into their ejected position, so that, for example, in the case of the electronics module 1 shown in FIG. This is the case at all eight hold and eject bays 6 . In this case, the cutout 20 is arranged in the adapter housing 8 such that the cutout 20 is in each case central between two electronics modules 2 in the plugged-in state of the adapter module 7 . When the two holding and ejecting brackets 6 are swung into the ejecting position, the right side longitudinal leg 18 of the first holding and ejecting bracket 6 on the left side and the left side of the second holding and ejecting bracket 6 on the right side The lateral longitudinal legs 18 can then engage simultaneously into the recesses 20 associated with the two electronics modules 2 arranged side by side.

Through the configuration of the recess 20 in the adapter module 7, the adapter module 7 can be arranged directly adjacent to the respective relay 5 in the longitudinal direction L of the respective electronics module 2, wherein nevertheless there is the possibility that the respective retaining and ejecting trays The rack 6 is swiveled into its ejected position. Therefore, the swing of the hold and eject bracket 6 is not hindered by the adapter module 7 adjacent to the relay 5 .

It can be seen from the illustration according to FIG. 6 of the adapter module 7 facing the rear side of the relay 5 in the plugged-in state that the adapter module 7 has two plug-in contacts 9 designed to contact a plug-in board, respectively, per electronic module 2 . . Between each pair of plug contacts 9 there is correspondingly arranged a fastening lug 21 , wherein the fastening web 21 and the two plug contacts 9 are part of a plug section 22 formed on the adapter housing 8 . In the case of an electronics assembly 1 with eight electronics modules 2 arranged side by side, the adapter module 7 therefore has eight plug sections 22 , wherein the adapter housing 8 is arranged between the individual plug sections 22 . Gap 20.

FIGS. 7a and 7b respectively show a sectional illustration along the line VII-VII indicated in FIG. Corresponding parts of the electronic module 2 and the adapter module 7 . The other six electronics modules 2 and the remainder of the adapter module 7 are by contrast not shown in FIG. 7 . Corresponding to each plug section 22 , a corresponding recess 23 is correspondingly formed in the base housing 3 of the respective electronics module 2 , as can be seen from FIG. 7 . Furthermore, fastening recesses 24 corresponding to the fastening lugs 21 are formed in the respective basic housing 3 , which adjoin the recesses in the interior of the basic housing 3 in the plug-in direction, that is to say viewed from the top side 3 a. 23 places. In the plugged-in state of the adapter module 7 , the respective plug sections 22 are therefore arranged in the respective recesses 23 and the respective fastening lugs 21 are arranged in the respective fastening recesses 24 , wherein the respective plug contacts 9 make contact with each other. Connect the corresponding mating contacts 11.

Furthermore, it can be seen from FIG. 7 that two detent hooks 25 are correspondingly formed in the fastening groove 24 , which form a detent connection together with two detent lugs 26 arranged on the fastening web 21 . In the case of all electronics modules 2 , respectively, two snap-in hooks 25 are formed in fastening recesses 24 , whereas only the two outer fastening tabs 21 of adapter module 7 (in FIGS. 7 a and 7 b respectively only the left The fastening tab 21) has a detent nose 26 corresponding to the detent hook 25. This is ensured by forming the detent lugs 26 corresponding to the detent hooks 25 formed in the detent grooves 24 of all base housings 3 only on the two outer fastening lugs 21 and not on all the fastening lugs 21 . Sufficiently secure locking of the adapter module 7 on the base housing 3 without the expenditure of force necessary to release the snap-in connection is not too great. In addition, the detachment of the snap connection is thereby facilitated and tilting of the adapter housing 8 is prevented, ie the two ejection levers 12 are arranged in the vicinity of the two fastening lugs 21 on which the snap noses 26 are formed. .

FIG. 7a shows the adapter module 7 in the locked state, in which the ejection lever 12 is thus in the first position shown in FIG. 4a. The detent lug 26 of the left fastening tab 21 is thus arranged below the detent hook 25 , whereby the fastening tab 21 is locked in the fastening groove. In contrast to this, in the illustration according to FIG. The detent nose 26 of 21 is arranged above the detent hook 25 . By pivoting the two ejection levers 12 according to FIG. 4 b from their first position into their second position, the adapter module 7 is only raised so far that the snap-in connection is released, while the fastening tab 21 is still in place. Its free end engages in the fastening groove 24 , so that the adapter housing 8 is also mechanically connected to the base housing 3 .

In particular, it can be seen from the perspective illustration of the adapter module 7 according to FIG. 5 that the adapter module 7 has a power supply port 27 in addition to the connection 10 . Furthermore, a plurality of LEDs 28 are provided, one LED 28 being associated with electronics module 2 in each case. In this case, the individual LEDs 28 are preferably used to indicate whether a defined voltage is present at the corresponding plug contact 9 . In order that the state of the individual LEDs 28 can then be easily and quickly detected by the user also when the holding and ejecting bracket 6 according to FIGS. 1 and 2 is in its ejected position, corresponding A recess 29 is formed, which is located above the associated LED 28 in the swiveled state of the holding and ejecting tray 6 .
