Description

The invention relates to a connector assembly with a conductor guide device, a lever and a CPA device. The invention further relates to a plug-in system with a connector assembly and a slot and a method for securing a connector assembly in a slot.

Electrical connectors can be designed as a CPA connector assembly with several elements and / or modules and have a conductor guide device as a main module and / or main element and / or main component of the connector. The conductor guide device guides electrical conductors and / or electrical contacts in its interior. The connector assembly has at least one lever as a second module and / or element and / or component with which the conductor guide device can be locked in a plug connection with a slot. The lock is configured as protection against unintentional loosening of the plug connection. The connector assembly also has a CPA device as a third element and / or module and / or component. "CPA" is an abbreviation for the English "connector position assurance". The CPA device is used to secure the lever in the locked position. This prevents the lever from moving from its locking position into an unlocking position, as a result of which the conductor guide device and thus the connector assembly are unlocked and can become detached from the slot.

Such connectors with CPA devices are used in particular in the automotive sector, e.g. as ABS connectors, i.e. anti-lock braking system connectors.

From the prior art, CPA connector assemblies are known in which the lever is fixed in its locking position by a detent which is formed on the conductor guide device. From a sufficient force, however, the lever can be moved back from its locking position to its unlocking position by deflecting the locking lug, which then releases the lever. In these previously known connector assemblies, a CPA device is used to prevent this deflection of the latching lug and thereby to secure the lever in its latched locking position. Only when the CPA device is moved away from the latching lug and releases the latching lug can the lever also be moved out of its locking position.

The previously known CPA devices have the disadvantage that they act on the locking lug, which is elastically movable and is loaded by the action. This can lead to wear and tear and, with repeated use, even to the locking lug breaking off.

The invention is based on the object of providing an improved connector assembly with a CPA device. For example, the task can be to provide an alternative, improved and / or low-wear connector assembly with a CPA device.

This object is achieved by the subjects of the independent claims. Preferred embodiments are the subject matter of the dependent claims.

One aspect relates to a connector assembly with a conductor guide device, a lever and a CPA device. The conductor routing device is configured to establish a plug connection with a slot in such a way that electrical conductors guided in the conductor routing device contact electrical contacts of the slot. The lever is arranged on the conductor guiding device and is movable between a locking position in which the lever locks the conductor guiding device in the plug connection with the slot and an unlocking position in which the conductor guiding device can be released from the slot. The CPA device is arranged on the ladder guide device and is movable between a secured position and an unlocked position. In its securing position, the CPA device forms a form fit with the lever for securing and / or fixing the lever in its locking position.

The connector assembly can be designed as a CPA connector assembly of the type mentioned at the beginning and / or as a multi-pin connector, in particular as a multi-pin connector for the automotive sector. The connector assembly can in particular be designed as an ABS connector assembly, that is to say a connector assembly for the anti-lock braking system of a motor vehicle. The connector assembly is constructed in at least three parts, the conductor guide device being designed as a base component and / or main component of the connector assembly on which both the lever and the CPA device are attached and arranged as a second and third component. A plurality of electrical conductors are routed inside the conductor routing device and are routed inside the conductor routing device to a plug-in and / or connection side of the conductor routing device. On this mating and / or connection side of the conductor guiding device, the conductor guiding device is designed to be plugged into the slot in such a way that the electrical conductors guided inside make electrical and / or mechanical contact with electrical contacts of the slot. The slot can be designed, for example, as a socket and / or complementary plug connector and / or have a circuit board to which the plug connector assembly can be electrically connected.

The lever is movably attached to the conductor guide device, in particular pivotably on and / or about a pivot axis and / or at least one pivot point. The lever can, for example, have a bow-like design and can be pivotably attached to the ladder guide device at two pivot points on its pivot axis. The lever is movable between its locking position and its unlocking position. The lever can be moved reversibly, i.e. the connector assembly can be locked and unlocked at the slot with the lever.

In the uncontacted and thus uninserted state, the lever is normally arranged in its unlocked position. At the same time, the CPA device is arranged in its unlocked position. To establish the plug connection, the conductor guide device is first placed on the slot with its plug and / or connection side. The lever is then moved from its unlocking position into its locking position. In this locking position, the lever locks the conductor guide device in a plug-in connection with the slot. The connector assembly can be configured in such a way that the plug connection itself is only established with the locking. In this case, the conductor guide device can no longer be unplugged from the slot without being destroyed as long as the lever is arranged in its locking position. In the locking position, there is a mechanical and / or form-fitting and / or force-fitting connection between the conductor guide device and the slot. In the locking position, the lever thus prevents the plug connection from being accidentally released.

Since the lever is reversibly movable back and forth between the locking position and the unlocking position, the lever can inadvertently release from its locking position. Such unlocking can be brought about, for example, by shaking and / or vibrating caused by a vehicle engine and / or driving movements. For this reason, the lever can be secured to the conductor guide device at least by means of a certain non-positive, frictional and / or positive basic connection. However, this basic connection is designed only up to a predetermined, comparatively small lever release force, since the lever movement should in principle be reversible. For example, the predeterminable lever release force for releasing the lever from its basic connection with the conductor guide device can be from about 15 N to about 150 N, preferably from about 80 N to about 120 N. the connector assembly also has the CPA device.

The CPA device is also movably attached to the ladder guide device. The CPA device is reversibly movable between the secured position and the unlocked position. At least when the lever is arranged in its locking position, the CPA device can be moved from its unlocked position into its secured position, in which the form fit between the CPA device and the lever is formed. This form fit prevents unintentional movement of the lever out of the locking position and thus unintentional unlocking of the conductor guide device.

The connector assembly has the advantage that the form fit between the CPA device and the lever directly blocks the unlocking movement of the lever, that is, a movement of the lever from its locked position into its unlocked position. The lever is thus not secured (as in the case of conventional CPA connector assemblies) indirectly via the detour of an action on a latching lug of the conductor guide device, but by means of a direct fastening and / or fixing of the lever. As a result, the stress on moving and therefore wear-prone parts, such as, for example, a latching lug of the conductor guide device, can be reduced and / or avoided.

The CPA device can still be moved back from its secured position to its unlocked position. This means that the form fit between the lever and the CPA device can be released again, so that the unlocked lever can then be moved from its locking position back into its unlocking position. In this case, the unlocking movement can, if necessary, take place with the application of the lever-releasing force required for this. This enables reversible securing and unlocking of the plug connection between the plug connector assembly, in particular the conductor guide device, on the one hand and the slot on the other hand.

In addition to the positive locking, the CPA device in the locking position can also have a non-positive and / or frictional connection between the lever and the CPA device in the Provide backup position. As a result, the securing of the lever in its locking position can be increased.

The fastening of the CPA device to the conductor guide device can be configured in such a way that the CPA device is fastened immovably to the conductor guide device in an unlocking direction. The unlocking direction corresponds to the direction in which the lever is moved out of its locking position in order to unlock the conductor guide device. Such a fastening of the CPA device has the effect that the positive fastening of the lever by means of the CPA device prevents the lever secured with the CPA device from being moved out of its locking position relative to the conductor guide device. The form fit can act in particular in the unlocking direction.

In one embodiment, the CPA device has at least one first projection element which, in the securing position, is at least partially arranged on a side of the lever facing away from the conductor guide device, whereby the form fit between the CPA device and the lever is provided. In the secured position, that is, when the lever is in its locking position and the CPA device is in its securing position, the first projection element engages behind the lever on a side facing away from the conductor guide device. The side facing away from the conductor guide device is one side of that part of the lever which forms the form fit with the CPA device. The section can be designed, for example, as a protruding tongue of the lever. In the secured position, the lever can thus be arranged at least partially between the CPA device on the one hand and the conductor guide device and / or another part of the CPA device on the other hand. The form fit can prevent the secured lever from being moved away from the conductor guide device. This movement of the lever away from the conductor guide device can be part of the unlocking movement, that is to say the movement of the lever from the locking position into the unlocking position. As a result of the form fit, the movement of the lever from its locking position into its unlocking position is blocked and / or hindered by the first projection element.

According to one embodiment, the CPA device has at least one second projection element and the lever has a through opening. The second projection element is visible through the through opening in the securing position. A visual indication can thereby be provided to indicate whether the CPA device is arranged in its secured position or not. In this case, the second protrusion element can be at least partially designed in a signal color such as red, for example, in order to increase the visibility of the second protrusion element through the through opening. If the second projection element is not visible through the through opening, the CPA device is also not yet in its secured position. In this case, the second projection element can be arranged directly adjacent to the through opening in the securing position. The second projection element can have an outer diameter which is formed larger than the inner diameter of the through opening. This enables the second projection element to fully engage behind and / or fill the through opening in the securing position. It is not necessary here for the second projection element to ever engage in the through opening. It can already be sufficient for the second projection element to be arranged in the securing position in a planar manner adjacent to and / or in contact with a part of the lever which is penetrated by the through opening. An effective display can thus be provided with simple mechanical means for checking the securing of the locked plug connection.

In a further development of this embodiment, the second projection element is arranged in the securing position at least partially on a side of the lever facing away from the conductor guide device, whereby the form fit is provided at least partially between the CPA device and the lever. In this embodiment, the second projection element can fulfill a double function.

However, this dual function is not absolutely necessary; the form fit can also be provided by another component such as the above-mentioned first projection element.

According to one embodiment, the CPA device has at least one receptacle for receiving a projection tongue of the lever. In this embodiment, the form fit is provided in that the projection tongue of the lever is inserted into the receptacle of the CPA device. The projection tongue can in particular be arranged on a lever end of the lever facing away from the pivot axis. This can maximize the securing effect of the form fit due to the law of leverage. The projection tongue can be received in the receptacle of the CPA device by moving the CPA device from its unlocked position into its secured position, the conductor guide device and the lever essentially in their Being able to remain in position, i.e. hardly need to be moved or not at all. During this securing, however, at least the position of the lever can change slightly in order to insert the projection tongue exactly into the receptacle.

In a further development, the first protrusion element limits the receptacle in an effective direction facing away from the conductor guide device and, in the securing position, forms the form fit with the protrusion tongue that acts in this effective direction. The effective direction can be the effective direction of the form fit and / or the unlocking direction. Here, the protruding tongue of the lever is fastened and / or fixed in the securing position by the first protruding element of the CPA device in a form fit. As a result, the lever is also fastened and / or fixed in its locking position.

According to a further development, the second projection element limits the receptacle in a direction facing the conductor guide device. This facing direction can be the opposite direction to the effective direction of the form fit and / or to the unlocking direction. Here, the first protrusion element and the second protrusion element can be designed to hold the protrusion tongue of the lever on both sides. This enables a particularly secure reception and thus fastening of the lever in its locking position.

In a further development, the projection tongue is arranged in the receptacle in the securing position in such a way that the lever is arranged essentially without play relative to the line guide device in the locking position. Conventional connector assemblies have the disadvantage that the lever has play relative to the line guide device in its locking position. This can be due, for example, to the fact that the lever is secured in its locking position by a movable latching lug of the conductor guiding device. The mobility of the locking lug can lead to the movement of the lever. However, this play can also cause the lever to rock due to vibrations, which can lead to unintentional loosening of the lever in the event of resonance, for example. The present development solves this problem in that the projection tongue is held essentially free of play in the receptacle of the CPA device. As a result, the lever is also arranged without play on the line guide device in its locking position. This reduces the risk of unintentional unlocking of the lever in the event of vibrations and / or similar forces.

According to a further development, the receptacle has a widening in the direction out of the receptacle and / or the projection tongue has a taper in the direction away from the lever and / or towards the receptacle. The widening and / or tapering is or are configured in such a way that threading and / or introducing the projection tongue into the receptacle is facilitated and / or supported. In particular, when the lever is held in its locking position with a certain amount of play, its position and thus the position of the projection tongue is not clearly defined. This can complicate threading and / or insertion of the projection tongue into the receptacle of the CPA device. The introduction is made easier by the widening and / or the tapering. The receptacle preferably has both the widening and the projection tongue the taper. The widening and tapering can each contain an inclined surface, such as, for example, inclined surfaces which, when the projection tongue is threaded in, slide against one another in such a way that the projection tongue is safely inserted into its desired position in the receptacle.

In one embodiment, the CPA device has at least one slide rail with which the CPA device can be moved along a rail guide of the line guide device between the securing position and the unlocking position. Alternatively, the CPA device can have the rail guide and the line guide device the slide rail. The CPA device preferably has two slide rails which are arranged in two rail guides. The rail guides can be configured in such a way that they only allow movement of the CPA device between the securing position to the unlocking position and back. This movement can be an essentially one-dimensional movement, with the rail guide preventing and / or reducing movements in the other two dimensions, i.e. in the directions perpendicular to this safety movement direction. The movement of the CPA device between the securing position and the unlocking position can be a linear movement and in particular include a displacement of the CPA device along an outer surface of the line routing device. One or more end stops can be provided which limit this one-dimensional, approximately linear movement of the CPA device along the rail guide on one or both sides, e.g. in the unlocked position and / or in the secured position of the CPA device.

In a further development, the at least one slide rail has an outer configuration that is movable along an inner configuration of the rail guide, the outer configuration of the slide rail being related to the inner configuration of the Rail guide is coordinated so that a predetermined force for moving the CPA device is defined. This force may be necessary to move the CPA. This force can prevent and / or reduce inadvertent movement of the CPA device out of the secured position. In this embodiment, for example, the slide rails of the CPA device can be structured on an outer surface facing the rail guide, e.g. have rounded projections and / or indentations that can interact with rounded projections and / or indentations of the rail guide when the CPA device is moved. As a result, ie through the precise shape of the bulges and / or indentations, a frictional force can be defined which has to be overcome in order to move the CPA device. If necessary, an elastic force can also be defined, for example to deform the slide rail and / or the rail guide when the CPA device is moved. In this way, the CPA device can in particular be secured in its securing position.

According to one embodiment, the plug connector assembly has a CPA fuse which secures the CPA device in a captive manner on the line routing device. The CPA securing device can, for example, contain a latching means which secures the CPA device on the line routing device. The latching means can, for example, comprise a latching lug formed on the conductor guide device and / or a latching recess formed in the CPA device. The CPA securing means in particular a movement of the CPA device beyond the unlocking position along the rail guide can be stopped and / or hindered.

In one embodiment, the CPA device can only be moved from the unlocking position into the locking position when the lever is arranged in its locking position. This prevents the CPA from being accidentally moved to the locked position before the lever is locked. This is because the CPA device could then impede and / or prevent the locking movement of the lever. This configuration can be implemented, for example, by at least one stop of the CPA device, which can be interrupted and / or deflected by the locked lever in such a way that the CPA device can be moved from the unlocked position into the secured position. Without the deflection and / or interruption of the stop, the CPA device cannot be moved from the unlocked position into the secured position.

One aspect relates to a plug-in system with a connector assembly according to the aspect described above and a slot with which the conductor routing device enters into a plug connection in such a way that the electrical conductors guided in the conductor routing device contact electrical contacts of the slot. In the plug connection, the lever is arranged in its locking position and the CPA device can be arranged in its securing position in order to secure the lever and thus the conductor guide device in the plug connection. Here, the slot can be designed, for example, as an associated complementary connector, as a socket, and / or as a circuit board with a connector. The plug connection can be reversibly secured by means of the CPA device of the connector assembly. Furthermore, the plug connection can be reversibly locked by means of the lever of the plug connector assembly.

One aspect relates to a method for securing a connector assembly with a line routing device, a lever and a CPA device at a slot with the following steps:

• - Establishing a plug connection between the conductor guide device and the slot in such a way that electrical conductors guided in the conductor guide device contact electrical contacts of the slot;
• Moving the lever, which is arranged on the conductor guide device, from an unlocking position in which the conductor guide device can be released from the slot to a locking position in which the lever locks the conductor guide device in the plug connection with the slot;
• Moving the CPA device, which is arranged on the ladder guide device, from an unlocking position into a securing position; and
• - Securing and / or fixing the lever in its locking position by forming a form fit between the CPA device and the lever, while the CPA device is arranged in the securing position.

The method can in particular be implemented with a connector assembly according to the aspect described at the outset. Therefore, all of the features and / or properties described in connection with the connector assembly also relate to the method and vice versa.

The steps of the method do not necessarily have to be separated in the sequence described above and / or do not necessarily have to be separated be carried out from each other. For example, the plug connection can be established by moving the lever. Thus, when establishing the plug connection, the conductor guide device can first be placed on the slot, so that only a mechanical contact is made without an electrical contact being made. The plug connection with electrical contact can be established, for example, when the lever is turned over, that is, when the lever is moved from its unlocked position into its locked position. Moving and thus locking the lever can also bring about and / or include a movement of the conductor guide device in the plugging direction onto the slot. Reliable electrical contact between the electrical lines of the connector assembly and the electrical contacts of the slot can only be established after the lever has been locked. Thus, the steps of producing a plug connection and moving the lever can take place at least partially at the same time.

One aspect relates to the use of the connector assembly described at the outset for establishing a plug connection with a slot.

In the context of this invention, the terms “essentially” and / or “approximately” can be used to include a deviation of up to 5% from a numerical value following the term, a deviation of up to 5 ° from one to the Direction following the term and / or from an angle following the term.

the 1A and 1B each show a perspective and a side view of a connector assembly 1 . The connector assembly 1 is essentially composed of three components, elements and / or modules, namely a conductor guide device 10 , a lever 100 and a CPA facility 200 .

Because of this, the connector assembly 1 may also be referred to as a CPA-securable connector assembly and / or CPA connector assembly.

The ladder guide device 10 forms a base body and / or a base component of the connector assembly 1 the end. The ladder guide device 10 can have a housing which is approximately cuboid and which encloses and / or contains electrical conductors (not shown in the figures). This inside the ladder guide device 10 guided electrical conductors are up to a mating side 11 the ladder guide device 10 guided. In the 1A and 1B is the mating side 11 than the lower side of the ladder guide device 10 educated. The ladder guide device 10 is designed to be with the mating side 11 first in the mating direction S. to be plugged into a slot, not shown, in order to produce electrical connections between the guided electrical conductors and electrical contacts of the slot, that is to say a plug-in connection between the conductor guide device 10 and the slot. The mating direction S. is approximately perpendicular to the mating side 11 educated.

The ladder guide device 10 extends essentially from the mating side 11 up to a fastening side 12th , which the ladder guide device 10 in one of the mating side 11 away from direction limited. General is the attachment side 12th that side of the ladder guide device 10 on which the lever 100 is applied in its locking position and / or on which the CPA device 200 is attached. The attachment side 12th can be approximately perpendicular to the direction of insertion S. be arranged. The ladder guide device 10 can still have at least two side walls 17th have which the conductor guide device 10 between the mating side 11 and the mounting side 12th limit to the outside. The side walls 17th can be roughly parallel to the plugging direction S. be arranged.

On two side walls facing away from each other 17th is the lever 100 at the ladder guide device 10 attached. Here is the lever 100 by two gift points 110 pivotable, of which only one in the 1A and 1B is shown.

The second pivot point 110 is on the side wall facing away from the viewer 17th educated. Normals on these two side walls 17th to which the lever 100 at the ladder guide device 10 attached, are referred to as lateral directions in the context of this description. These lateral directions are approximately perpendicular to the insertion direction S. arranged and thus approximately parallel to the mating side 11 .

In the in 1A and 1B situation shown is the lever 100 arranged in its unlocking position, in which he is at least one unlocking stop 14th supports. The unlocking stop 14th can be on one or more of the side walls 17th be trained. The unlocking stop 14th limits the pivoting movement of the lever 100 in the unlocked position.

The lever 100 furthermore has a pivoting end 120 on which one of the pivot points 110 spaced end of the lever 100 is arranged. The lever 100 is like this on the ladder guide device 10 attached that its pivoting end 120 around the pivot points 110 is pivotable around, in particular pivotable to the fastening side 12th the ladder guide device 10 . In the in the 1 Unlocking position shown is the pivot end 120 from the ladder guide device 10 and / or the fastening side 12th swiveled away and thus, for example, against the plug-in direction S. spaced therefrom.

The CPA facility 200 is also on the ladder guide device 10 attached, namely movably attached. In the in the 1 The situation shown, the CPA device is arranged in its unlocked position. The CPA facility 200 is basically displaceable along part of the fastening side 12th educated. In the embodiment shown, however, the CPA device cannot easily be displaced from its unlocked position into the secured position, so as not to inadvertently lock the lever 100 to block. As in the 1 shown can be the CPA facility 200 for example adjacent to a cable duct 13th be arranged. The ladder guide device 10 can guide the cable 13th for guiding cables, for example around electrical cables with the inside of the conductor guiding device 10 to connect led lines electrically.

2A and 2 B show the same connector assembly 1 as the 1 . In contrast to the 1 is the lever 100 in the 2 pivoted into its locking position. To move the lever 100 from the in the 1 unlocking position shown in the 2 The locking position shown can be the lever 100 for example at its pivoting end 120 around the at least one pivot point 110 around on an outer surface of the conductor guide device 10 be pivoted, then the fastening side 12th . When pivoting the lever 100 from the unlocking position to the locking position, i.e. when locking the lever 100 , becomes the connector assembly 1 locked by a mechanism not shown in the figures with the slot, not shown, and thus attached thereto.

While the connector assembly 1 in the in the 1 shown unlocking position with the plug side 11 can be plugged first onto the slot, not shown, this connector is not yet locked and thus relatively easy to detach from the slot. Only after the connector assembly has been locked 1 , so moving the lever 100 in the in the 2 locking position shown is the connector assembly 1 so firmly connected to the slot that it can no longer be detached from it without destroying it. For example, the connector assembly 1 be configured to be positively and / or non-positively connected to the slot in the locked state.

In the locking position, at least one can be on a side wall 17th the ladder guide device 10 trained locking nose 15th into a recess in the lever 100 engage and the lever 100 secure something against a lever releasing force. However, this is an easily detachable fuse, not a sufficiently stable fuse for the automotive sector. A sufficiently strong securing against lever release forces of, for example, more than 100 N or 200 N can only be achieved by means of the CPA device 200 to be provided.

In the embodiment shown in the figures, the lever is 100 pivotable about a pivot axis which is approximately parallel to the plug-in side 11 is arranged in the lateral direction. This pivot axis SW is for example in 5A indicated by a dashed line. The pivot axis SW extends through the ladder guide device 10 through the two pivot points 110 of the lever 100 . The shown fastening of the lever 100 at the two pivot points 110 , i.e. on the two side walls facing away from each other 17th the ladder guide device 10 , increases the stability and longevity of the lever movement. In an alternative embodiment, the lever could 100 also only at a single pivot point 110 , e.g. only on one side wall 17th , with the ladder guide device 10 be pivotably connected.

The lever 100 can basically be designed in the shape of a bow. The lever extends 100 from the first pivot point 110 along a first lever arm up to the pivot end 120 , which forms a bracket head. The swing end 120 extends approximately parallel to the pivot axis SW of the lever 100 between those of the pivot axis SW spaced lever arm ends. From the swing end 120 extends the lever 100 continue along the second lever arm back to the second pivot point 110 , which is hidden in the figures. While the pivot points 110 on opposite side walls 17th the ladder guide device 10 are formed, connects the pivot end 120 the two lever arms of the lever 100 together.

The pivot end is in the locking position 120 on the fastening side 12th pressed, in an area of the room approximately adjacent to the CPA facility 200 is arranged. In the 2 is the CPA facility 200 still arranged in their unlocked position, just as in the 1 . This means that the lever 100 is arranged in its locking position, but is not yet secured there by the CPA device 200 .

3A and 3B show in a perspective view and in a side view the in the 1 and 2 Connector assembly shown 1 . In contrast to the figures described above, in the 3A and 3B however the CPA facility 200 moved to their secured position. In doing so, the CPA facility 200 from the in the 1 and 2 shown unlocking position on the pivot end 120 moved so that it is the pivoting end 120 positively fixed.

The Movement of the CPA Facility 200 from their unlocked position to the 3 The securing position shown is done by moving it along the fastening side 12th . Quite generally, the movement of the CPA device can be 200 by sliding along an outer surface of the conductor guide device 10 take place. In the embodiment shown, this sliding movement is a movement approximately perpendicular to the insertion direction S. (and here also perpendicular to the lateral directions) aligned direction along the mating side 11 facing away from the fastening side 12th . This is the CPA facility 200 preferably on this mating side 11 arranged facing away from the outside, so in the exemplary embodiment on the fastening side 12th in order to have a particularly effective form fit with the lever 100 , more precisely that Panning end 120 of the lever 100 to train. The swing end 120 Due to the long lever travel, it is particularly suitable for securing the lever 100 in its locking position.

Is the connector assembly 1 like in the 3A and 3B locked, ie is the lever 100 placed in its locked position, and secured, ie is the CPA device 200 in its secured position, so can the connector assembly 1 can no longer be removed from the slot in a non-destructive manner. However, this only applies as long as the CPA facility 200 not back in their unlocked position and the lever 100 is not moved back to its unlocked position.

In the embodiment shown, both the safety movement is the CPA device 200 as well as the locking movement of the lever 100 reversible. This means that the locked and secured plug connection of the connector assembly 1 can also be released again, ie unlocking by moving the CPA device 200 into their unlocked position and unlocking by moving the lever 100 in its unlocked position.

4th shows a perspective view of a section of the conductor guide device 10 the connector assembly 1 at which the CPA facility 200 is attachable. Here the section is without the CPA facility 200 shown. 4th shows one for cable routing 13th adjacent section of the conductor guide device 10 . In particular, in 4th a section of the fastening side 12th shown on which in the locking position the pivot end 120 of the lever 100 is placed (cf. 1 until 3 ). On the fastening side 12th instructs the ladder guide device 10 a lever system 30th on. The lever system 30th is designed as a projection on and / or around the pivot end 120 on the fastening side 12th is launched. It can be provided on the lever system 30th also a locking connection with the pivoting end 120 of the lever 100 can be produced to define the unsecured lever release force.

Adjacent to this, in the exemplary embodiment shown, between the lever system 30th and the cable routing 13th , is on the attachment side 12th a rail guide 20th formed, between which a sliding surface 21 is trained. The sliding surface 21 is in this case as a substantially flat outer surface of the fastening side 12th educated. The sliding surface 21 serves as a base and / or support for the CPA facility 200 (see. 1 until 3 ). On and along the sliding surface 21 can the CPA facility 200 can simply be moved. Approximately in the middle of the sliding area 21 can still use a CPA locking device 16 be trained. The CPA locking device 16 can be designed as a latching lug, in particular as a pivotable latching lug, with which the CPA device 200 at the ladder guide device 10 can be attached. The CPA locking device 16 can thus be designed as a CPA fuse.

The sliding surface 21 is on opposite sides of a rail guide 20th limited. Here, the conductor guide device 10 In the embodiment shown, two rail guides running approximately parallel to one another 20th on. Each of the two rail guides 20th runs essentially parallel to and / or in the plane of one of the two side walls 17th the ladder guide device 10 . The rail guides 20th are used to guide the slide rails of the CPA equipment 200 , which are described in more detail in the following figures. The rail guides 20th are as elongated projections on the mounting side 12th formed which a movement of the CPA device 200 block in at least one lateral direction. For example, any rail guide 20th comprise some kind of outer wall which allows lateral movement of the CPA device 200 from the fastening side 12th via the immediately adjacent side wall 17th addition prevented.

Furthermore, each of the rail guides 20th have an encroachment which the CPA facility 200 in the assembled state at least partially overlaps so that the CPA device 200 between the mounting side 12th (more precisely the sliding surface 21 ) and this overlap of the rail guides 20th is jammed. Here is the overlap of the rail guide 20th on one of the mounting side 12th facing away from the CPA facility 200 arranged so that the overlaps in the direction of the other rail guide 20th point. The encroachments thus prevent the CPA device from moving from the attachment side 12th away, so a lifting off the mounting side 12th in an approximately perpendicular to the mounting side 12th aligned direction. In particular, the attacks may involve a movement of the CPA facility 200 against the direction of insertion S. limit while the attachment side 12th or more precisely the sliding surface 21 a move of the CPA facility 200 in the mating direction S. limited. The encroachments on that of the fastening side 12th remote end of the outer walls of the rail guides 20th can thus make an important contribution to the fixation of the CPA device 200 in the direction of action of the form fit with the pivoting end 120 and / or afford in the unlocking direction.

The elements of the rail guide described so far 20th and the sliding surface 21 thus limit the movement possibilities of the CPA facility 200 in two perpendicular to the mating direction S. guided lateral directions across the sidewalls 17th out and both in and against the mating direction S. . Furthermore, the CPA facility 200 so on the ladder guide device 10 be attached that the sliding movement of the CPA device 200 is limited both in the secured position and in the unlocked position.

In the exemplary embodiment shown, the CPA device 200 therefore essentially only carry out a linear movement, however neither beyond the safety position nor beyond the unlocking position. For this purpose, stops can be provided, for example, against which the CPA device 200 strikes in the secured position and / or in the unlocked position. One of these attacks can at least be an unlocking stop 24 be which in 4th is shown. The unlocking stop 24 is in the embodiment shown as a curved projection between the rail guide 20th and the lever system 30th on the fastening side 12th formed, in particular adjacent to and / or laterally adjacent to the sliding surface 21 . The function of the unlocking stop 24 which here on both lateral sides, i.e. on the two opposite side walls 17th , is designed, is described in more detail with reference to the following figures.

On the rail guide 20th can still have a safety stop 23 be designed, which extends as an extension of the overlap on the outer wall of the rail guide to the interior of the conductor guide device 10 extends on one of the mounting side 12th facing away from the CPA facility 200 . Here is the safety end stop 23 as an extension of the above-described overlap of the rail guide 20th in the direction of the other rail guide 20th educated. Also the function of the safety end stop 23 is described in more detail below with reference to the following figures.

Roughly parallel to the outer walls of the rail guides 20th instructs the ladder guide device 10 two swivel spaces 22nd which as recesses in the sliding surface 21 and each adjacent to the outer walls of the rail guides 20th are trained. The swivel spaces 22nd serve to swivel out slide rails of the CPA device 200 , which are described in more detail with reference to the following figures. In the embodiments shown, both the rail guides extend 20th as well as the swivel spaces 22nd approximately parallel to each other, namely parallel to the linear direction of movement of the CPA device 200 , in which the CPA device can be moved from its secured position to its unlocked position and back.

In the embodiment shown, the conductor guide device 10 exactly two rail guides each 20th , two safety end stops 23 , two release end stops 24 and two swivel spaces 22nd on.

5A Figure 3 shows a perspective view of the lever 100 the connector assembly 1 . As already described is the lever 100 with respect to its pivot axis SW pivotable on the connector assembly 1 arranged and attached. The pivot axis SW extends through the two pivot points 110 , which in the assembled state on opposite sides, more precisely on the side walls 17th , the ladder guide device 10 are arranged.

The lever 100 has two lever arms 140 which are each roughly from one of the pivot points 110 to the end of the swing 120 extend. In each of the lever arms 140 can be a snap shot 141 be designed as a recess which is used to receive the in the 2 locking tab shown 15th is trained.

In the vicinity and / or adjacent to the pivot axis SW is on the lever arms 140 each one toothing 150 educated. The gearing 150 can comprise a plurality of teeth and in particular be designed similar to a section of a gearwheel. The gearing 150 is configured to engage in a counterpart (not shown in the figures) at the slot in such a way that the plug-in side is locked 11 takes place at the slot, and thus a locking of the connector assembly 1 at the slot. The gearing 150 is in each case at one of the pivoting ends 120 remote end of the lever arms 140 arranged.

At the end of the swing 120 points the lever 100 a support surface 160 on. The supporting surface 160 is with respect to the direction of extension of the lever arms 140 slightly angled. The supporting surface 160 is so with respect to the lever arms 140 angled that they are in the in the 2 and 3 shown locking position of the lever 100 approximately parallel to the outer surface of the conductor guide device 10 , more precisely the mounting side 12th , is trained and aligned. This allows the support surface 160 in the locking position at least partially flat on the fastening side 12th be in place, cf. 2 and 3 .

At the end of the swing 120 is still roughly in the middle of the lever 100 a protrusion tongue 130 educated. The protrusion tongue 130 can be that fulcrum of the lever 100 include which on farthest from the pivot axis SW is spaced. The protrusion tongue 160 can be used as an extension of the pivoting end 120 and / or the support surface 160 approximately in the direction of the pivot axis SW be trained away.

5B shows an enlargement of the pivot end in a perspective view 120 of the lever 100 . Here is shown how the protrusion tongue 130 as a flat extension of the pivoting end 120 and / or the support surface 160 is trained. Immediately adjacent to the projection tongue 130 or even through this is at the pivot end 120 furthermore a through opening 131 formed, which the pivot end 120 and / or the support surface 160 and / or the protrusion tongue 130 completely penetrates. The through opening is in the locking position 131 essentially parallel to the plug-in direction S. arranged. The protrusion tongue 130 is in the locking position essentially parallel to and / or at least partially resting on the fastening side 12th arranged. The protrusion tongue 130 can be the furthest from the pivot points 110 spaced point of the lever 100 include.

6A , 6B and 6C show the CPA facility 200 in a perspective view, in a plan view in the plugging direction S. and in a side view in a lateral direction.

The CPA facility 200 has a sliding floor 260 on which one is on the sliding surface 21 the ladder guide device 10 can be moved (see also 4th ). The sliding floor 260 be designed to be essentially completely flat in order to be easy to move relative to the sliding surface 21 to be movable. The CPA facility 200 is designed to work with the sliding base 260 on the sliding surface 21 the ladder guide device 10 to be arranged.

The CPA facility 200 continues to have a base 250 on, which is designed as a thickening and which extends from the sliding base 260 on opposite to the plugging direction S. extends. At the base 250 are essentially all components of the CPA facility 200 educated. Furthermore is the base 250 so thickened that the base 250 can be contacted by an operator's finger for easy movement of the entire CPA device 200 .

The CPA facility 200 has two slide rails 240 on, which is in an assembled state of the connector assembly 1 inside the in 4th shown rail guides 20th are arranged. The slide rails 240 extend approximately parallel to one another from the base 250 away along the sliding floor 260 . Each of the slide rails is in the assembled state 240 approximately perpendicular to the direction of insertion S. arranged. The slide rails 240 extend from the base in the assembled position 250 away, roughly along the fastening side 12th and towards the lever 100 to (cf. also 3 ).

The slide rails 240 point each at their the base 250 remote end a thickening 241 on which is from the sliding floor 260 away against the plugging direction S. as a thickening extends. Each of the slide rails 240 is only one-sided at the base 250 attached while the other, the base 250 remote end can be resiliently pivoted as a free end. At the free end of the slide rails 240 is the thickening 241 educated.

Furthermore, each slide rail 240 on the side of the thickening 241 which the free end and thus the lever in the assembled state 100 is facing, a stop step 242 on. At the base 250 facing side has any thickening 241 a paragraph 243 on. How the thickening works 241 , of the paragraph 243 and the stop level 242 is described in more detail with reference to the following figures.

From the base 250 away towards the lever 100 , i.e. in the assembled state roughly parallel to the fastening side 12th , a first protrusion element also extend 210 and a second protruding member 220 the CPA facility 200 . The second projection element extends here 220 essentially along the sliding floor 260 . The second protrusion element 220 can thereby (e.g. together with the undersides of the slide rails 240 ) essentially the sliding floor 260 form. The first protrusion element 210 can be opposite to the plugging direction S. spaced from the second protrusion member 220 be arranged and approximately parallel to the second projection element 220 extend, so in the assembled state in the direction of the lever 100 there.

The two protruding elements 210 and 220 form (see e.g. the in 6C side view shown) a recording 230 between themselves. The recording 230 extends in the plugging direction S. between the two projection elements 210 and 220 . The recording 230 serves to accommodate the protrusion tongue 130 of the lever 100 (see. 5 ). Each of the two protruding elements 210 and 220 is essentially plate-shaped, the plates in the assembled state being essentially parallel to the fastening side 12th and thus to an outer surface of the conductor guide device 10 are trained. It is in the second projection element 220 a locking recess 261 trained, which in assembled state with the, for example, in 4th CPA locking means shown 16 cooperates.

The recording 230 is designed so that it faces towards the lever 100 to and / or from the base 250 widens away. In the exemplary embodiment shown, this is due to a bevel 211 on the first protrusion element 210 causes. The bevel 211 enlarges the picture 230 towards the lever 100 there.

Each of the slide rail 240 has an outer contour 244 on, which is formed, for example, as a bulge and / or a projection in the direction which, in the assembled state, the side walls of the rail guide 20th is facing. In the embodiment shown, this outer contour 244 at the end of the slide rails 240 be formed, which at the base 250 is attached.

In the top view of the 6B are the outer contours 244 therefore shown as protrusions in lateral directions. The lateral directions are directions perpendicular to the insertion direction S. , which are also roughly normal to the opposite side walls 17th form (cf.e.g. 1A) . The outer contours 244 be designed as rounded projections, that is, without hooks and / or step-free, in order to ensure safe sliding and / or sliding in the rail guides 20th to enable.

7A , 7B and 7C each show a section through a section of the connector assembly 1 . The cut is through one of the two slide rails 240 the CPA facility 200 placed. It is in the three 7A , 7B and 7C the connector assembly 1 each shown in a different state: In 7A is the lever 100 unlocked and the CPA facility 200 unlocked, just like in the 1 . In 7B is the lever 100 locked and the CPA facility 200 unlocked, just like in the 2 . In 7C is the lever 100 locked and the CPA facility 200 secured, just like in the 3 .

The section in the figures is exactly in the middle through one of the slide rails 240 guided so that the mating direction S. is arranged parallel to the cutting plane. The cutting plane is furthermore essentially parallel to and between the two side walls 17th the connector assembly 1 (see 1 until 3 ).

In the 7A until 7C is still only a section of the connector assembly 1 shown, namely that section on which the CPA device 200 is arranged as well as the pivoting end in the locking position 120 of the lever 100 .

In 7A is the lever 100 in its unlocked position, as well as in the 1A and 1B shown. That's why the lever is 100 from the in 7A Swiveled away section shown and thus not shown. However, the CPA facility is shown 200 as well as the cut through its base 250 and their slide rail 240 . The CPA facility 200 is like this on the attachment side 12th the ladder guide device 10 arranged that all elements of the CPA facility 200 from the base 250 away towards the lever 100 and / or to the lever system 30th extend, so in particular the slide rails 240 , the first protruding member 210 and the second protruding member 220 . The latter are not in 7th shown for this in the following 8th .

Every slide rail 240 is in the assembled state exactly above the swiveling space assigned to it 22nd arranged. This means that the slide rail 240 in the swivel space 22nd can be pivoted in, in particular with its free end, on which the thickening is also 241 is arranged. However, there is no sufficient pivoting force on the slide rail 240 acts in the swiveling space 22nd is directed into it, is the slide rail 240 itself arranged essentially in a straight line and not pivoted. The sliding floor lies here 260 (see. 6th ) flat on the sliding surface 21 the ladder guide device 10 on (see also 4th ).

In the in 7A The state shown is the CPA facility 200 arranged in their unlocked position. Each is the slide rail 240 in the respective rail guides 20th guided so that the slide rail 240 in the mating direction S. between the overlap of the rail guide 20th and the mounting side 12th is held. From above, i.e. from the ladder guide arrangement 10 facing away, the safety stop in particular engages 23 over the slide rail 240 and thus prevents the CPA device from lifting off 200 against the direction of insertion S. . Furthermore, both overlaps of the rail guides engage 20th via the two slide rails arranged in each case 240 so the CPA facility 200 essentially over the entire surface of the fastening side 12th the ladder guide device 10 is held.

7A further shows that the slide rail 240 with their stop level 242 on an edge of the release stop facing the CPA device 24 the ladder guide device 10 strikes. This causes the CPA facility 200 not unintentionally out of their unlocked position out into the safety position, so here in the direction of the lever system 30th is movable.

Paragraph 243 the thickening 241 can at least partially on the safety end stop 23 nudge to move the CPA set up 200 to hinder in the opposite direction, so away from the lever stop 30th continue to cable routing 13th there. The safety end stop can 23 contribute to the definition of the unlocking position.

7B shows how in contrast to the 7B the lever 100 is pivoted into its locking position, as well as in the 2 shown. The pivot end is in its locking position 120 on the lever system 30th at. The lever system is used for this 30th to define the locking position of the lever 100 .

At the end of the swing 120 is still a deflection process 121 educated. The articulation process 121 is at the ladder guide device 10 facing side of the pivot end 120 formed and points in the plugging direction S. on the fastening side 12th . The articulation process 121 presses in the in 7B position shown approximately in the plugging direction S. on the thickening 241 the slide rail 240 . In general, the deflection process 121 somewhere near the free end on the slide rail 240 act so that the slide rail 240 at least at its free end a little way into the swiveling space 22nd is swiveled in. This is where the slide rail 240 deflected at least so far that the stop step 242 no longer at the release stop 24 is present. This will block the CPA facility 200 canceled. This enables the CPA facility 200 from the in 7B unlocking position shown in 7C shown securing position can be moved, namely along the surface of the mounting side 12th the ladder guide device 10 towards the lever 100 and towards the lever stop 30th in an approximately perpendicular to the mating direction S. arranged direction. When securing the CPA facility 200 , that is, when moving the CPA device 200 The slide rails slide from the unlocked position to the secured position 240 along the rail guides 20th . The sliding floor continues to slide 260 the CPA facility 200 on the sliding surface 21 along.

The CPA facility 200 can towards the lever stop 30th be pushed until the base 250 at the safety end stops 23 strikes. These thus define the security position as in 7C shown. The slide rail is in the secured position 240 pivoted back into its rest position, since the deflection process is here 121 no longer on the thickening 241 rests, but on a thinner section of the slide rail 240 . This means that there is no deflection of the slide rail 240 does more.

The paragraph continues to be in the secured position 243 the thickening 241 with its the base 250 facing side on the release stop 24 at. The release stop is in this situation 24 at the same time a certain stop for the safety position. The unlocking stop can be in the secured position 24 so with the paragraph 243 work together that there is some resistance to inadvertent opening of the CPA device 200 results from the secured position out into the unlocked position. The CPA device can 200 at the base 250 away from the pivot end 120 be pulled, e.g. in the direction of the cable guide 13th there. The paragraph is effective 243 with its inclined surface so with an opposing bevel of the release stop 24 together that the slide rail 240 in the swivel space 22nd is steered into it, similar to that in 7B situation shown. This enables the CPA device to be opened and unlocked 200 enables.

In the in 7C locked and secured position of the connector assembly 1 is the release end stop 24 in one of the fastening side 12th facing recess in the lever end 120 recorded. The release end stop 24 is at least from three sides of the pivoting end 120 surround.

8A , 8B and 8C show exactly that in the 7A until 7C states of the connector assembly shown 1 , but along a different cutting plane. In the 8A until 8C is the cut roughly in the middle of the CPA device 200 , the lever 100 and the ladder guide device 10 placed, parallel to that in the 7A until 7C section plane shown. Thus it lies in the 8th The section plane shown is no longer through one of the slide rails 240 through, but centrally through both the first projection element 210 as well as the second protruding element 220 the CPA facility 200 exactly between the side walls 17th .

In 8A is the lever 100 not shown, since this is arranged in its unlocked position. That’s the lever 100 not in the 8A shown section swiveled in. The second protrusion element 220 lies with its the ladder guide device 10 facing side on the sliding surface 21 on. The second projection element is located here 220 especially on the CPA locking device 16 on (cf. 4th ) its locking lug into the locking recess 261 in the sliding floor 260 the CPA facility 200 intervenes. The CPA locking device 16 secures the CPA facility 200 captive on the ladder guide device 10 . The locking lug of the CPA locking means prevents this 16 in particular that the CPA facility 200 towards the cable guide 13th and away from the lever stop 30th can be moved away. The CPA locking device 16 is thus designed as a stop, which the unlocking position of the CPA device 200 defined in the direction of the lever 100 path.

8B shows the connector assembly 1 , with the lever here 100 in its locking position on the fastening side 12th the ladder guide device 10 is swung open. Here is the projection tongue 130 of the swing end 120 on the second protrusion element 220 placed, which in turn on the fastening side 12th rests. The passage opening 131 is not yet on the second projection element 220 on. The passage opening 131 penetrates the pivot end 120 in the locking position essentially parallel to the plug-in direction S. . In this state it is between that of the conductor guide device 10 facing end of the through opening 131 and the ladder guide device 10 a cavity is formed.

8C shows how the CPA facility 20th so to the lever 100 is pushed that the projection tongue 130 in the recording 230 is incorporated into the CPA facility 200 between the first protruding member 210 and the second protruding member 220 trains. The recording 230 extends in particular in the plug-in direction S. , ie in a direction approximately perpendicular to the mounting side 12th the ladder guide device 10 .

The one in the 8B shown locking position of the lever 100 is not necessarily designed to be free of play. This means that the protrusion tongue 130 possibly not completely on the second projection element 220 must rest, but can optionally be arranged somewhat at a distance from it. This game in the direction of insertion S. of the swing end 120 is reduced and / or no longer present in the embodiment shown at the latest when the securing position is set. The protruding tongue is in the secured position 130 substantially free of play between the first projection element 210 and the second protruding member 220 in the recording 230 held. The first protruding element forms 210 with the protruding tongue 130 a form fit that unlocks the lever 100 prevents and / or counteracts this.
