Electrical plug-in system

Field of the invention

The invention relates to an electrical plug-in system with a plug and a plug-in module.

State of the art

In a vehicle, numerous electrical and electronic control units are installed in the engine compartment and in the body space, which must be electrically connected to each other and to other components of the vehicle, such as sensors and actuators.

For this purpose, a plug-in module can be located on a control unit whose

Male connector may have some 100 poles. A corresponding plug, which is connected to a cable harness, can be plugged into the plug-in module to establish the electrical connection. For this purpose, the plug may have a lever which engages in a rack on the plug-in module and pulls the plug in the direction of the plug-in module during a closing movement.

For such a plug with lever, the connector between the harness connector and male connector is designed non-sealing, as the

Rack disposed internally on a collar of the cartridge and the shaft on the lever engaging the rack prevent a seal from being disposed between the collar and the plug. Due to the missing seal, the electrical contacts of the plug-in module and the plug are the partially aggressive media in the engine compartment or

Body room exposed.

Furthermore, the plug lever can usually be mounted only in one orientation on the plug. Also, the connector can usually only be closed or locked on one side.

Disclosure of the invention

It is an object of the invention to provide a flexibly assemblable plug-in system for a wiring harness of a vehicle.

This object is solved by the subject matter of the independent claims. Further embodiments of the invention will become apparent from the dependent claims and from the following description.

One aspect of the invention relates to a plug-in system with a plug and a plug-in module, wherein the plug is designed for establishing an electrical connection to the plug-in module. For example, the plug-in module may be attached to a control unit of a vehicle, such as a motor controller, and the plug may be connected to a wiring harness of the vehicle. Plug and plug-in module can have more than 100 individual electrical contacts that can be made for example via miniaturized electrical contacts, for example, have a cross section of 0.5 mm to 0.4 mm and which are arranged in a grid of 1.8 mm. Such plug-in systems can be used for example in a vehicle (car, truck, bus). The plug-in module can be attached to a control unit, for example. The plug can be used to connect the controller, such as a motor controller, to a wire harness.

Embodiments of the invention advantageously allow to provide a variable plug-in system for a control unit of a vehicle, in which the Plug lever and a guide of the electrical lines in the plug, ie a cable passage, can be mounted in several orientations on the plug.

According to one embodiment of the invention, the plug of the

Plug system, a plug body in which a plurality of electrical contacts is received and which has a connector base which is adapted to receive a collar of the plug-in module. Further, the plug comprises a plug lever which is adapted to be moved from a starting position to an end position and thereby the plug by means of a lever arm, which in the

Plug-in module engages to pull in the direction of the plug-in module. In this way, the plug can be positioned with the connector base on the collar and be controlled by a lever movement with the lever connected to the plug-in module. By the movement of the plug lever, which for example is a shaft with teeth, which engage in corresponding projections on the collar, a translational movement can be generated in which about more than 100 electrical contacts are pushed together without being accidentally damaged (folded over) become. Next can be achieved with the plug lever a very large mechanical transmission ratio, so that the plurality of electrical contacts can be pushed into one another without difficulty.

Furthermore, the plug has at least one sealing element which is designed to seal the plug inserted into the plug-in module with respect to an environment of the plug. In particular, the plug lever is designed so that the interior of the plug can be sealed by sealing elements, such as a radial seal and / or a mat seal. For example, the plug lever from the outside to attack the collar of the plug-in module, while the sealing element is pressed against an inner side of the collar.

For example, the plug can be designed such that the plug lever can be mounted in two orientations on the plug body and the lever arm and the plug-in module engage in the two orientations in such a way that the plug can be pulled in the direction of the plug-in module. By the

inventive design of the plug-in system can be made possible, the plug lever in two about 180 ° to each other rotated positions attach the plug and securely connect the plug in both positions by means of the plug lever with the plug-in module.

Overall, the plug-in system can be designed to provide a flexible and variable with respect to a positioning of the plug connector and at the same time a durable and stable electrical connection between electrical lines of a wiring harness in a vehicle and a

To provide control unit. A number of sensors and actuators installed in vehicles, as well as corresponding control units that process information from the sensors and that can control the actuators, are steadily increasing. In a vehicle, however, a space available for sensors, actuators, and control units may be severely limited, so that these components of the vehicle are increasingly manufactured in miniaturized construction. This also applies to the associated plugs and plug-in modules with which electrical connections between the components can be made. Therefore, it may also be necessary, the plug and plug modules in flexible and variable

Making construction so that they correspond to the available space in a vehicle type in different positions on a

Control unit can be attached.

According to one embodiment of the invention, the plug lever engages around the plug body with two lever arms, which are connected to a crossbar. At the two lever arms, which may be parallel to each other and extend to the crossbar as a lever handle orthogonal waves may be located at the ends, which are accommodated in the connector base and around which the plug lever can be moved. The waves can be about in

corresponding openings in the connector base and be movable. The openings may be formed symmetrically in the connector base and symmetrically on two opposite sides of the

Be arranged plug body so that the plug lever can be mounted in two about 180 ° to each other rotated positions on the plug. According to one embodiment of the invention, a lever arm of the

Plug lever on a shaft about which the lever is movable and in the direction directed the plug body. The wave can be teeth, such as a

Lever tooth and / or a stop tooth, which are designed to engage in the plug-in module. For example, the teeth can engage in a corresponding rack on the plug-in module. The plug lever may be a rack lever.

According to one embodiment of the invention, the shaft has a

Stop tooth, which is designed to, in the starting position on a

Projection to be supported on the collar.

According to one embodiment of the invention, the shaft has a lever tooth which is designed to engage around the projection, the lever tooth pulling the plug into the plug-in module when the lever is moved from the starting position into the end position.

According to one embodiment of the invention, the shaft has only a lever tooth and only one stop tooth, which are arranged orthogonal to a longitudinal direction of extension of the shaft of the shaft. The longitudinal extension direction of the shaft can be defined by the axis of rotation about which the shaft can be moved in the plug body. A

Design and geometry of the shaft, each with only one lever tooth and a stop tooth can also be made relatively easy and inexpensive to produce.

According to one embodiment of the invention, the lever tooth is formed longer than the stop tooth, so that the lever tooth projects further from the shaft than the stop tooth. This can be relatively large

Lever forces are generated, which may be necessary to pull the plug and the plug into each other. A relatively large lever tooth can also be made robust, so that the insertion forces occurring when the plug and the plug-in module plug into each other can be overcome by the lever forces without the lever tooth damaged, such as can be canceled.

According to one embodiment of the invention, the collar of the plug-in module has a plug-in channel, which is adapted to receive the shaft, wherein the Plug channel of the collar symmetrical with respect to the orientations of

Plug lever is formed. In other words, in both orientations in which the plug lever is mountable on the plug body, the shaft can equally be received by the plug channel of the collar, so that in both orientations by moving the plug lever of the

Starting position in the end position, a translational movement can be generated, in which the plug and the plug-in module for establishing an electrical connection are pushed into one another. The plug-in channel can be understood as a rack and the shaft as a rack lever.

The plug-in channel can be arranged on an outer side of the collar. It can also have two plug-in channels on two opposite

Outer sides may be formed on the collar, each receiving a shaft of a lever arm of the plug lever.

According to one embodiment of the invention, the plug-in channel along a direction of insertion into the plug-in channel, a first portion which provides two symmetrical projections, a second portion, the two symmetrical

Provides recesses, and a third section, which provides two more symmetrical projections on. The symmetrical configuration of the plug-in channel can ensure the function of the shaft and the lever tooth in both orientations of the plug lever.

According to one embodiment of the invention, the projections of the first and third portions of the plug-in channel protrude equally far into the channel. This may allow the shaft to piece in the third section of the

Plug channel can be pushed without abutting a projection of the channel, which in turn can ensure that the plug and the

Plug module can be pushed far enough into each other to make an electrical connection.

According to one embodiment of the invention, the lever tooth of the shaft in the starting position of the plug lever surrounds a projection of the plug channel, wherein the lever tooth is designed to be pushed when moving the plug lever from the starting position to the end position in a recess and thereby the plug and the plug-in module to merge. At the collar of the Plug-in module must be in this way only a single lead or

Counter tooth, with which the lever movement in one

Translational motion can be converted. When using a single projection this can be made relatively large, so that even large forces can be transmitted.

According to one embodiment of the invention, the stop tooth of the shaft is supported in the starting position of the plug lever on the collar on a projection, wherein the stop tooth is designed to release the projection when moving the plug lever from the starting position to the end position. The projection may be located on the outside of the collar of the plug-in module.

According to one embodiment of the invention, the plug-in system further comprises a plug cover having a cable passage for guiding electrical

Having lines from the plug body. In this case, the plug cover can be fastened in two orientations on the plug body, so that the cable duct in the two orientations can guide the electrical leads in different directions out of the plug body. The

Orientations of the plug cover and thus the directions with which the electrical leads are guided out of the plug body, can be rotated about 180 ° to each other. Also with regard to a potentially limited space in a vehicle can in different

Orientations executable cable passage be beneficial. Thus, after a plugging operation of the plug with electrical leads, i. a connection of the plug with a cable harness, such as a Kabelkonfektionär, the cable passage to be subsequently changed or adapted to a space. Also, a flexibility in terms of the cable gland cost savings in production, since for both orientations of the cable gland only a plug or a plug-in system must be produced. Furthermore, this eliminates the need for a replacement insert for different orientations of the plug cover and the cable gland.

Furthermore, the plug has at least one sealing element, which is designed to plug the plug inserted into the plug connector with respect to an environment of

Seal plug. In particular, the plug lever is designed so that the interior of the plug can be sealed by sealing elements, such as a radial seal and / or a mat seal. For example, the plug lever from the outside to attack the collar of the plug-in module, while the sealing element is pressed against an inner side of the collar.

According to one embodiment of the invention, the connector base has a

Plug on which is designed to be pushed into the plug-in module. The connector base may, for example, a ring element or

Have jacket element which guides the shaft of the plug lever, in the interior of which a further annular plug element is mounted. The ring element and the plug-in element can receive the collar of the plug-in module between them. The male member may be surrounded by a radial seal (i.e., a sealing ring) adapted to be received between the male member and the collar. The radial seal can thus seal the collar from the inside.

According to one embodiment of the invention, the plug has a

Matt seal, which is located between the connector base and a plug cover. The mat seal may have channels for receiving leads to the electrical contacts. Together with the radial seal, the mat seal can close the space formed by the plug and plug-in module.

According to one embodiment of the invention, the plug lever at one end of a lever arm on a securing pin which abuts in the starting position on a stop element on the plug base, so that a movement of the plug lever from the starting position is prevented in the end position. In this way it is prevented that the plug is positioned in an unwanted position on the plug-in module, so that, for example, the teeth on the lever are not arranged in the directional position or the plug can be partially pushed onto the plug-in module, without the plug lever used to help becomes.

The securing pin may be configured to be pushed away from the plug base by a pressure of a ramp on the plug module so that the securing pin slides over the stop member and the plug lever releases. With the security pin in this way a Prestop is integrated into the plug. The plug lever remains in the start position until the safety pin is released. The plug lever can only be operated when the plug is placed on the plug-in module and the ramp

Release safety pin.

According to one embodiment of the invention, a further stop element is provided on the plug base, against which the securing pin abuts in the end position, so that a movement of the lever beyond the end position is prevented. This can prevent the plug and the plug-in module from being pulled too far towards each other.

According to one embodiment of the invention, the plug comprises a

Plug fuse or plug position assurance, comprising a sliding element in a crossbar of the plug lever and an unlocking pin on a plug cover, wherein the sliding member is slidable from an unlocked position to a locked position when the sliding member is pressed against the unlocking pin. With the plug fuse, the plug can only be locked when the plug lever is safely in the end position. The plug fuse is integrated into a plug and checks whether the plug lever is really in the end position in which all electrical connections between the plug and plug-in module have been made and in which all sealing elements are sealed. With the plug fuse can then be protected before opening the plug lever. To open the plug lever, the plug fuse must be unlocked.

Basically, identical or similar parts are the same

Provided with reference numerals. EMBODIMENTS OF THE INVENTION FIG. 1 shows a plug-in system 10 comprising two harness connectors 12a, 12b and two

Plug-in modules (or male connector) 14a, 14b. Both plugs 12a, 12b are in an end position, in front of the interior of the connector system

sealed external influences and in which all electrical contacts are in communication.

The plugs 12a, 12b are symmetrical to a median plane of the plug-in system 10, and the plug-in system 10 is designed such that the plugs 12a, 12b can be inserted antisymmetrically into the plug-in modules 14a, 14b.

The two plug-in modules 14a, 14b are accommodated in a common, one-piece housing 16.

Each plug 12a, 12b has a plug body 16 with a plug base 18 and a plug cover 20 which supports the plug base 18 at the side

closes, which is opposite to the side of the connector base 18, which is plugged onto the plug-in module 14a, 14b.

A plug lever 22 of each plug 12a, 12b surrounds the plug body 16 in a U-shape with two arms 24. At the ends of the arms 24 are each one

Shaft 26. The two shafts 26 of a plug lever 22 are in

opposite openings 28 received in the connector base 18.

The plug base 18 includes a guide groove 30 in which a shaft 26 located on the rail 32 is received, which is a movement of the associated

Lever arm 24 prevents in the axial direction.

The plug lever 22 has a transverse bar 34, which connects the two arms 24 and in which a plug-in fuse 36 is mounted (see Fig. 6 ff.). Each plug 12a, 12b and the associated plug-in module 14a, 14b have a miniaturized pitch of 1.8 mm and are designed in 6 rows. The pins in the plug-in module 12a, 12b have a cross section of 0.5 mm to 0.4 mm. This allows more contacts to be accommodated in a smaller space.

2 shows a longitudinal section through the plug-in system 10. The plug 12a is in a starting position, the plug 12b is shown in an end position.

When plug 12a can be seen that the plug-in module 14a (as well as the plug-in module 14b) has an edge / collar 38 on which the plug 12a is placed in the starting position. The arm 24 of the first connector 12a is placed in the starting position on the cover 20 of the second connector 12b.

3 shows the plug-in system 10 in a cross-sectional view, in which the two levers 22 are cut on one side of the plug-in system 10. FIG. 3 shows that a movement of the lever 22 from the starting position into the end position pulls the plug-in module 14a into the plug 12a. The collar 38 is located in the connector base 18th

4 shows the plug-in system 10 in a cross-sectional view, in which the two shafts 26 are cut on one side of the plug-in system 10. On each shaft 26 are a stop tooth 40 and a lever tooth 42. Both teeth 40, 42 are projections which project from the shaft 26.

In the starting position, the stop tooth 40 in a direction transverse to

Plug-in direction and the lever number 42 along the direction of insertion. On the collar 38 is located outside a projection 44 on which the stop tooth 40 is discontinued in the starting position. The plug base 18 protrudes in the starting position while already on the collar 38 to position the plug 12a, 12b so that the stop tooth 40 is placed accordingly.

When the lever 22 is moved to the end position, the shaft 26 rotates and the lever tooth 42 engages under the projection 44 and pulls the plug 12a, 12b or its base 18 and the plug-in module 14a, 14b or the collar 38 towards each other. The stop tooth 40 moves so that it releases the projection 44 and can slide past the projection 44. In the end position, the stop tooth 40 in a direction opposite to the insertion direction and the lever tooth 42 in a direction transverse to the insertion direction.

Below the projection 44 may be another projection 46, which prevents the lever tooth 42 can be further moved in the insertion direction to fix the plug 12a, 12b in the end position.

The two projections 44, 46 can be considered as a rack with two teeth 44, 46. A mirror-symmetrical arrangement of teeth or a toothed rack can be located on the same side of the collar 38 on the plug-in module 14a, 14b. In this way, the same collar 38 can be used for the two plug-in modules 14a, 14b.

The teeth 44, 46 and the projections 44, 46, between them a

Plug channel for the shaft 26 in the plug-in module 14a, 14b form will be described in more detail below with reference to FIGS. 10 and 11.

5 shows a cross section through the plug 12a at the level of two ramps 48 of the plug-in module 14a. The plug 12a is replaced by a

Radial seal 50 and mat seal 52 sealed.

The plug base 18 has a ring or jacket element 54 which surrounds the collar 38 in the end position and which is flush with the collar 38 on the outside. The sheath element 54, like the collar 38, may have a rectangular cross-section and be annular in shape.

Next, the connector base 18 has a central or plug-in element 56 which is enclosed by the collar 38 in the end position. Between the

Sheath element 54 and the plug element 56 is an annular recess for receiving the collar 38th

The radial seal 50 surrounds the plug element 56 on an outer wall. To make room for the radial seal 50, the collar 38 at the

Be tapered inside at an outer end. The plug-in element 56 is shorter in the plugging direction than the casing element 54 and is enclosed by the radial seal 50, which bears in the end position between the inner wall of the collar 38 and the outer wall of the plug element 56 in a sealing manner.

Through the plug element 56 run guide channels 58 for receiving lines of a wiring harness. The central element 56 includes chambers 60 for receiving contact elements, in which pins can be inserted from the plug-in module 14a.

Between the plug base 18 and the plug cover 20 is a mat seal 52 having channels 62, can be passed through the lines and which seals the interior of the plug 12a from the environment.

At the plug lever 22, at the ends of the arms 24 is a

Securing pin 64, which points in the direction of the plug body 16 (inwards) and which, when the plug lever 22 is in the starting position and no force acts on the pin 64, rests against a housing element 66, so that the plug lever 22 does not move in the direction of the end position can be.

The edge of the housing element 66, on which the pin 64 abuts, extends substantially orthogonal to the lower edge of the plug 12a. In addition to the collar 38 is a ramp 48 on which the pin 64 for

Lying comes when the plug 12a is placed on the plug-in module. By pressing on the plug 12a, the pin 64 is pressed onto the ramp 48 and pushed away from the plug body 16 by the ramp 48 so that the pin 64 slides over the housing member 66 and releases the plug lever 12a. In this case, deforms the region of the lever 22 which is connected to the pin 64.

During the movement from the starting position to the end position of the lever 22, the pin 64 is guided via a ramp 68 on the plug body 16 until it is in the end position on a further housing or stop element 70 (see FIG. 3) is applied, which prevents a movement of the lever 22 beyond the end position.

The plug base 18 and the collar 38 are symmetrically constructed in a longitudinal and a transverse direction. The lever 22 is constructed symmetrically to the longitudinal direction. The pins 64 are located on both sides of the lever. The ramp 38, ramp 68 and stop elements 66, 70 are located on both sides of the connector base 18 and the collar, wherein on each side two of these components are arranged.

FIG. 6 shows a cross-section through the plug 12a along a plane parallel to the longitudinal direction of the plug-in system 10, which is outside the plug

Symmetrieebene lies.

The plug fuse 36 or plug position assurance 36 includes a

Sliding element 72 which is slidably mounted in the crossbar 34 of the lever 22. However, the sliding member 72 is prevented in the unlocked position shown in Fig. 6 by a locking element 74 of the plug lever 22 therein to slide in a locked position. The sliding element 72 has in its front edge a groove 76 which can receive an edge of the latching element 74.

On plug cover 20 is a Entsicherungszapfen 78 which presses when pressing the lever 22 on the cover 20 against the sliding member 72 and this deformed, so that this no longer rests on the locking element 74 and can be pushed over it. For this purpose, the sliding element 72

then to the groove 76, a first ramp 80.

The cover 20 and the crossbar 34 are constructed symmetrically to a center plane of the plug-in system 10. The sliding element can therefore have two grooves 76, the lever 22 two locking elements 74 and the cover 20 two Entsicherungszapfen 78.

FIG. 7 shows a cross section through the plug 12a along the

Plane of symmetry. Analogous to FIG. 6, the sliding element 72 is in the unlocked position in which the lever 22 and the cover 20 are not locked together.

The sliding member 72 has a latch 82 which is designed to be pushed into a bracket 84 on the cover 20, so that the lever 22 can not be moved away from the cover 20.

FIG. 8 shows a cross section analogous to FIG. 6, in which the

Sliding element is in the locked position. The sliding member 72 has a switch 86 with which it can be moved to the locked position. For this purpose, the sliding element 72 is pushed over the locking element 74, where it abuts a further ramp in the lever 22 at a ramp subsequent to the locking element 74. In this position, the sliding member 72 can be moved back by the operation of the switch 86 in the unlocked position in which it bends away from the locking element 74, since the two ramps slide against each other.

FIG. 9 shows a cross section similar to FIG. 7. In the locked position, the latch 72 is pushed into the bracket 84. The latch 72 has at its leading edge a bevelled portion which facilitates insertion into the bracket 84.

10 shows a perspective detailed view of the plug lever 22 with the two U-shaped lever arms 24, which are connected to the crossbar 34. In this illustration, the two shafts 26, which are located at the ends of the lever arms 24 are clearly visible.

Each shaft 26 has a rail 32 which is received in a guide groove 30 in the opening 28 of the connector base 18 and the lever arms 28 fixed with respect to an axial direction which may be defined by the plugging direction. Furthermore, each shaft 26 has in each case only one lever tooth 42 and one stop tooth 40, which project from the shaft 26 at approximately 90 ° offset from one another orthogonally to a longitudinal direction of extension of the shaft 26.

The opening 28 of the connector base 18 may be formed primarily circular, with a further recess may be provided in the connector base 18 can, which may be configured to be complementary to the lever tooth 42 and which may adjoin the opening 28, so that the shaft 26 can be guided with the lever tooth 42 through the opening 28. Further, the opening 28 may be formed symmetrically with respect to a median plane through the opening 28, that is, it may be two complementary to the lever tooth 42 formed

Recesses may be provided at the opening 28, through which the lever tooth 42 can be guided. Furthermore, two openings 28 may be arranged symmetrically on two opposite sides of the plug body 16. The lever tooth 42 is further than the stop tooth 40 from the shaft 26, so that when moving the plug lever 22 from the starting position to the end position and the associated rotation of the shaft 26 by means of the lever tooth 42 sufficiently large leverage can be generated to about the for a plug-in insertion of the plug 12a, 12b and the plug-in module 14a, 14b to apply necessary insertion forces.

FIG. 11 shows a perspective detail view of the plug-in module 14a, 14b of the plug-in system from FIG. 1. A plug-in channel 90 is located on each of two opposite outer sides of the collar 38. The two plug-in channels 90 of a plug-in module 14a, 14b are each configured with a shaft 26 of the two lever arms 24 of a plug lever 22 to record.

The collar 38 forms a bottom 91 of a plug-in channel 90. On a side opposite the bottom 91, i. a side facing away from the collar 38, the plug-in channel 90 for receiving the shaft 26 is open. Will the plug

12a, 12b put on the plug-in module 14a, 14b, the two shafts 26 of the plug lever 22 are on two opposite sides of the

Plug body 16 respectively in the openings 28 of the connector base 18th

taken, each shaft 26 is received by a plug-in channel 90 on the plug-in module 14a, 14b.

Each mating channel 90 has along the mating direction a first portion 92 providing two symmetrical protrusions 44, a second portion 94 providing two symmetrical recesses 96, and a third portion 98 providing two further symmetrical protrusions 46. The Projections 44 of the first portion 92 protrude the same distance in the

Plug-in channel 90 as the projections 46 of the third portion 98th

Overall, the first, the second and the third section 92, 94, 98 of the plug-in channel 90 can be configured as a thickening of the collar 38, wherein they surround the bottom 91 of the plug-in channel 90 and project from the collar 38. Collar 38 and plug-in channel 90 can be configured in one piece or multi-piece. The first, second and third sections 92, 94, 98 of the plug-in channel 90 can thus form channel walls of the plug-in channel 90. In a multi-piece embodiment, the channel walls of the plug-in channel 90, for example, by plastic injection molding, plastic welding,

Ultrasonic welding, gluing or riveting be attached to the collar 38.

The plug-in channels 90 are configured symmetrically with respect to the first, the second and the third section 92, 94, 98. In other words, those are

Plug channels 90 and the channel walls designed mirror-symmetrically with respect to a center plane through the plug-in channel along the insertion direction.

The symmetrical configuration of the projections 44, 46 and the recesses 96 and the symmetrical configuration of the channel walls of a plug-in channel 90 allows the plug lever 22 to be mounted in two orientations on the plug body 16, wherein the lever arms 24 and the plug-in module 14a, 14b in both orientations engage in such a way that the plug 12a, 12b is pulled by moving the plug lever 22 from the start position to the end position in the plug-in module 14a, 14b. In other words, the plug-in channels 90 are symmetrical with respect to the orientations of the plug lever 22, so that the plug-in channels can receive the shafts 26 in both orientations of the plug lever 22. As already explained in detail in FIG. 4, the stop tooth 40 is in the

Start position supported transversely to the direction of insertion on the projection 44 of the first portion 92 of the plug-in channel 90 and the lever number 42 protrudes along the

Insertion direction in the plug-in channel 90 into and surrounds the projection 44. When moving the plug lever 22 in the end position, the shaft rotates 26, the stop tooth 40 releases the projection 44 and slides on the projection 44th past. At the same time the lever tooth 42 engages under the projection 44 and pulls the plug 12a, 12b into the plug-in module 14a, 14b or in the collar 38. The lever tooth 42 is thereby pushed into the recess 96 of the plug-in channel 90. In the end position, the stop tooth 40 points in a direction opposite to the plugging direction and is located in the first section 92 of the plug channel 90, whereas the lever tooth 42 points in a direction transverse to the plug direction and projects into a recess 96 in the second section 94 of the plug channel 90 (see FIG also Fig. 4). FIG. 12 shows a side view of the plug-in system 10 from FIG. 1, wherein the

Plug lever 22 of the plug 12a, 12b are shown in the end position and mirror-symmetrically with respect to a median plane through the connector system 10, which is orthogonal to the plane of FIG. 12, are arranged. The plugs 12a, 12b each have a plug cover 20. One

Connector cover 20 may, for example, a to an edge region of the

Plug body 16 have complementary shaped boundary 101, so that the plug cover 20 can be fixed, for example by positive engagement and / or by adhesion to the plug body 16.

The edge region of the plug body 16 and the complementary edge 101 of the plug cover 20 are also symmetrical with respect to two orientations in which the plug cover 20 can be mounted on the plug body 16. The orientations of the plug cover 20 may be rotated about 180 ° to each other.

The plug cover 20 also has a cable passage 100 for guiding electrical lines from the plug body 16. According to the orientation of the plug cover 20, the cable duct 100 leads into the two

Orientations the electrical wires in different directions from the plug body 16th

In the plug-in system 10 shown in FIG. 12, the plug lever 22 and the plug cover 20 are each mounted in anti-symmetrical orientation to each other on the plug 12a, 12b. That is, the plug cover 20 and the plug lever 22 are mirror-symmetrical with respect to the median plane through the plug-in system 10th arranged so that the cable runs 100 facing in opposite directions. The electrical leads are therefore routed through the cable ducts 100 in opposite directions out of the plug 12a, 12b.

Fig. 13 shows a plug-in system 10, in which the plug lever 22 and the plug cover 20 are mounted in the same orientation to each other on the plug 12a, 12b, so that the cable ducts 100 point in the same direction. In the plug-in system 10 shown in FIG. 13, therefore, the electrical lines are each guided out of the plug body 16 on the right-hand side.
