Description

Plug connector component group

Technical Field

The invention relates to a plug connector component group. The plug connector component group is provided for electrical connection to a mating plug connector component group. The invention further relates to a plug connector arrangement having such a plug connector arrangement and to a mating plug connector arrangement.

Background

A plug connector assembly is known from DE 102013212914 a 1. Plug connectors are used, for example, in the automotive sector and in the commercial vehicle sector. The plug connector arrangement can have a plug connector with a plug connector housing, in short a housing, and contacts arranged therein. They can also have a mating plug connector with a mating plug connector housing and a mating contact arranged therein. The plug connection is established when the plug connector and the mating plug connector are connected, for example, by plugging together along the z-axis or by inserting the plug connector into the mating plug connector or by plugging the plug connector onto the mating plug connector. In this case, insertion forces, for example contact forces when the contact lug is sprung open (Aufschn ä beln) or sealing forces of the sealing gasket arranged in the element must be overcome. In order to keep the plug force to be applied at a reasonable level, for example 75N, a lever can be provided on the plug connector, which lever is provided to reduce the plug force, for which purpose a longer actuation travel is to be accepted. The lever can be mounted in a known manner on the housing, for example, by means of a shaft and has a gear or tooth geometry on the inside of the housing. This tooth geometry can engage in a complementary tooth geometry on the mating plug connector housing, which serves as a toothed rack. However, it is also possible to form a slot in the lever, into which a pin (Zapfen) on the mating plug connector housing engages.

When the plug connector is plugged onto the mating plug connector, the lever is usually in a first position, which may also be referred to as the starting position. By displacing the lever, for example by rotating it clockwise, the gear wheel of the lever meshes with the toothed rack of the mating plug connector housing and thus pulls the housing onto the mating plug connector housing. In this case, the contact and the mating contact are brought into mechanical and electrical contact and the connection is closed.

Fig. 1 shows an exemplary prior art plug connector arrangement, in which a connection is established between a plug connector 3 and a mating plug connector.

Fig. 1 schematically shows a spatial representation of a plurality of plug connectors 3 which can be used, for example, for electrically contacting a cable harness with a control device of a vehicle. The plug connectors 3 each have a housing 2 in which electrical contacts are present. Furthermore, a U-shaped lever 4 is mounted on the housing of each plug connector 3, said lever being rotatably mounted on the housing 2 at a bearing point 10.

In fig. 1, the plug connector 3 has been connected to a mating plug connector, which is covered by the plug connector 3, and the lever 4 is displaced into a second or end position.

Disclosure of Invention

The plug connector component group according to the invention enables a quick and simple assembly of a plurality of plug connectors on a mating plug connector. In particular, individual actuation of each lever is avoided. Advantageously, therefore, a plurality of plug connectors can be connected to the corresponding mating plug connector in a single assembly step or by means of a single movement process, either simultaneously or in succession in a simplified manner. If the plug connectors are connected one after the other to the corresponding mating plug connector, it can be understood here, for example, that the individual plug connectors briefly pass one after the other in the z direction during the assembly process through a position at which (local) maxima of the plug force are present (for example by the spring-out of the contact pieces) in order to thus better distribute the operating forces during the movement process.

According to the invention, a plug connector component group comprising or having at least two plug connectors is specified. The plug connectors each have a housing. Each plug connector can be connected to a mating plug connector along the z-axis, for example by plugging in or plugging in. Electrical contacts may be disposed within the interior of each housing. The electrical contacts are used to electrically contact mating contacts of a mating plug connector. In this way, an electrical connection between the plug connector and the mating plug connector can be achieved.

At least one lever is arranged on each housing for reducing the actuating force when connecting the plug connector to the corresponding mating plug connector. As mentioned above, the lever can have, for example, at least one tooth or a sliding groove. The teeth or the sliding grooves can, for example, engage in complementary elements on the mating plug connector. The mechanical connection of the plug connector to the mating plug connector can thus be realized by means of the lever.

In order to achieve a mechanical connection between the plug connector and the mating plug connector, each lever is rotatably mounted on the associated housing at a mounting point. The rotation can take place, for example, about a lever rotation axis. The lever axis of rotation is oriented, for example, parallel to the x axis, which in turn is oriented perpendicular to the z axis. The lever is rotatable between a starting or first position and a terminal or second position. When the plug connector and the mating plug connector are plugged together, the plug connector is pushed (aufsetzen) onto the mating plug connector in the starting position by means of the lever. In the starting position, the plug connector and the mating plug connector can also be separated again. In this position, it is provided that the tooth or the sliding groove is located, for example, shortly before mechanical engagement with a complementary element on the mating plug connector. If the lever is subsequently rotated into the end position, the complementary elements on the plug connector lever and the mating plug connector (e.g. teeth and rack or runner and pin) engage one another and the plug connector and the mating plug connector are thereby connected to one another. In other words, a relative movement between the plug connector and the mating plug connector along the z-axis is achieved by a rotation of the lever, so that the plug connector and the mating plug connector move towards each other to their final relative position. The electrical contact of the electrical contact and the mating contact can thereby be simplified in that the actuating force is reduced on the basis of the lever transmission ratio.

Since the plug connector component group has at least two plug connectors, at least two levers are provided. In order to simplify the actuation of these levers, actuating elements are provided. The actuating element is operatively coupled to all levers of the plug connector component group in such a way that the levers can be moved from a starting position into an end position and vice versa by moving the actuating element in a single direction. In this case, for example, a single movement may be sufficient, i.e. no "pumping" is required. The movement may for example be a translational movement or a rotational movement. The expression "in a single direction" should be understood to mean that the fitter does not have to reciprocate the actuating element, i.e. to "pump" the lever from the starting position into the end position, but that, for example, a movement only from left to right or, for example, a clockwise rotation is sufficient to displace the lever from the starting position into the end position. For example, for a displacement from the end position to the starting position, an opposite direction of movement of the actuating element can be implemented.

In particular, therefore, it is not necessary to actuate each lever individually, but rather the levers of the plug connector component group can be moved only by movement of the actuating element. In this way, the assembly time is reduced. The actuation of the individual levers by means of the actuating element can take place simultaneously or successively during the course of the movement of the actuating element.

Furthermore, it is advantageously possible that a predefined assembly sequence to be enforced is not disrupted, since the movements of the levers can no longer be carried out independently of one another due to the actuating element. Rather, the sequence in which the individual levers are actuated is determined unambiguously by the design of the actuating element. It is furthermore advantageously possible to provide the plug connector of the plug connector component group in a prefabricated manner. This plug connector component group is therefore easier to transport and easier to fit on a mating plug connector, for example in difficult or narrow installation situations, than when each plug connector has to be mounted individually on its associated mating plug connector or connected thereto.

The dependent claims contain preferred developments of the invention.

Preferably, the actuating element has at least one connecting track. The connecting rails mechanically connect all the levers, wherein the levers are rotatably mounted on the connecting rails at a respective one of the receiving points.

Preferably, the displacement is carried out such that the lever and the connecting rail can be rotated relative to one another about the receiving point rotation axis. The accommodation point rotation axis may be oriented, for example, parallel to the x-axis. The mechanical connection between the connecting rail and the lever can be realized, for example, in a force-locking and/or form-locking manner, for example, by clamping the connecting rail at the receiving point. The connecting rails can thus be connected to the respective levers in a simple manner, for example after the plug connectors have been arranged or positioned relative to one another. For example, the connecting rail may have a plurality of openings into which the pins of the respective levers engage.

The connecting rail advantageously allows the levers to be actuated simultaneously or one after the other by means of a mechanical connection, wherein, for example, only the connecting rail can be moved, for example, by an assembly person, for example, by means of an actuating element. Thus, with a movement of the connecting rail in a unique direction (for example a translational direction or a rotational direction), i.e. without "pumping", it is possible to carry out a manipulation of all levers and here to move all levers between a starting position and an end position when closing the plug connection or from the end position to the starting position when releasing the plug connection.

Furthermore, it is preferably provided that a separate lever is respectively mounted on two opposite sides of the housing along the x-axis. Thus, each housing is provided with a pair of levers. All levers on each side are connected by a respective one of the connection tracks, so that there is one connection track on each side of the housing. This means that each lever pair of different plug connectors is arranged in such a way that one of the levers of the lever pair is connected to its own connecting rail. The connection rails are therefore advantageously located on the sides of the housing of the plug connector lying opposite one another along the x axis. This advantageously achieves that all levers are moved simultaneously on both sides, so that tilting of the plug connector and the mating plug connector is avoided.

In a particularly advantageous embodiment, the connecting rails are connected by connecting elements. The connecting rail and the connecting element are preferably constructed in one piece. In this context, "integrally" means in particular that the connecting rail and the connecting element cannot be separated from one another without damage. The unit consisting of the connecting rail and the connecting element is, for example, an injection-molded part. This allows a simple and cost-effective production of the actuating element, which in this embodiment is formed by the connecting rail and the connecting element.

In one embodiment, it is particularly advantageously provided that the connecting rails are separate components. Furthermore, it is provided that the two levers mounted on one of the housings, i.e. in particular one of the lever pairs, are designed as U-shaped additional levers. The U-shaped additional lever is rotatably mounted both at two bearing points on the housing and at the respective receiving point on the two connecting rails. The bearing can be realized, for example, in such a way that a relative rotation of the additional lever and the housing and of the additional lever and of the connecting element, respectively, about a rotational axis oriented parallel to the x-axis is possible. The axis of rotation may be, for example, a receiving point-axis of rotation or a bearing point-axis of rotation.

This advantageously achieves that all levers of the plug connector component group are actuated by actuating a single lever, i.e. the additional lever. In other words, by shifting the additional lever from the starting position to the end position, it is possible to achieve that all other levers are likewise shifted from the starting position to the end position. Of course, this also applies to the opposite movement, that is to say to the transfer of the additional lever and the remaining levers from the end position into the starting position. This makes it possible to mount the plug connector component group on the mating plug connector component group in a simple and cost-effective manner. Advantageously, the movement of the additional lever can be realized in a rotational movement. This advantageously maintains a customary course of movement for the fitter. Furthermore, advantageously, the fitter can thus always apply a tensile or compressive force perpendicular to the lever axis, thereby maximizing the torque. In contrast, when the force acts purely translationally, the component perpendicular to the lever axis depends on the angle of the lever axis relative to the direction of translation.

The additional lever advantageously projects beyond the lever, so that the additional lever advantageously projects beyond the connecting track. The additional lever therefore has a greater length than the lever, wherein the length is the distance between the bearing point and the point furthest from the bearing point in the y-z plane. This advantageously enables a larger transmission ratio, that is to say: the fitter needs to apply a smaller actuating force to connect the plug connector component group with the mating plug connector component group.

For example, the additional lever has a length which is at least 20%, preferably at least 40%, particularly preferably at least 50%, and very particularly preferably at least 100% (i.e. double length) longer than the length of the lever. The length can be determined from the bearing point to the uppermost end of the lever or of the additional lever.

In a preferred embodiment, the additional lever is formed in one piece. As a result, it can advantageously be produced particularly simply, for example as an injection-molded part. The additional lever can be designed, for example, in a U-shape and then fastened to a respective support point on both sides of the housing.

In an alternative preferred embodiment, the additional lever is formed by two levers and a U-shaped sleeve (Aufsatz) to the levers. Therefore, the lever of the plug connector component group is not different. In order to form an additional lever, the attachment is mounted on only one lever pair, that is to say on two levers arranged on the housing. It is particularly advantageous if the sleeve can be removed without damage, for example by clipping back, removing the plug, etc. This makes it possible in particular to remove the sleeve after the plug connector component has been assembled to the mating plug connector component. This again advantageously means that the sleeve is used only for displacing the lever from the starting position into the end position. The sleeve is removed once the lever is in the end position, which makes it possible to save installation space for the plug connector component group.

This makes it possible, for example, to install the control devices in the motor vehicle more closely to one another. In order to achieve a possibly required release of the plug connection, the sleeve can then be placed again on the lever pair, in order to thus form an additional lever. Furthermore, it is advantageously achieved by the sleeve that different lever pairs are used as additional levers, depending on the installation situation. If, for example, three plug connectors are arranged in the plug connector arrangement, the sleeve can be attached, for example, to one of the outer lever pairs or also to the intermediate lever pair. Furthermore, the sleeve advantageously makes it possible to assemble the cover or the cover element before or also after the plug connection is established. Since the upper side of the plug connector facing away from the mating plug connector is accessible as soon as the sleeve is removed and the individual covers of the plug connectors or the cover elements overlapping all plug connectors can also be fitted without problems. This advantageously increases the flexibility in assembly.

The sleeve can particularly advantageously be adjusted relative to the lever on which the sleeve is mounted. Whereby the length of the attachment lever can be adjusted. The length is again particularly advantageously the spacing between the bearing point and the point furthest from the bearing point in the y-z plane. The assembly force can advantageously likewise be varied by varying the length of the attachment lever. Thus, due to the increased length of the additional lever, the displacement to be taken by the additional lever between the starting position and the end position increases, but at the same time the operating force to be applied to the additional lever decreases. The optimum ratio between the actuating travel and the actuating force of the additional lever can thus be set advantageously by means of the variable length. Depending on the type of plug connector or mating plug connector used, the mechanical stability of the complementary structures on the lever (gear element, runner, etc.) and the mating plug connector (rack, pin, etc.) can also be adjusted so that they are not overloaded.

The plug connector component group advantageously has a cover element. A plurality of plug connectors can be accommodated on the cover element. The cover element is preferably arranged on the side of the housing of the plug connector which is not in contact with the mating plug connector. In other words, the cover element is mounted on the side of the plug connector facing away from the mating plug connector.

By accommodating a plurality of plug connectors by the cover element, it is advantageously achieved that the plug connectors of the plug connector-component group (and possibly also other plug connectors, for example without levers) can be connected to the cover element first, for example in a good working environment. The whole (ensembles) thus formed can then be provided as a complete unit, for example for mounting on a mating plug connector component group, and mounted on the mating plug connector component group. Since this step can occur in narrow space conditions and/or in poor viewing conditions, it is advantageous if only one unit has to be installed and a cover element protecting the plug connector from dirt, dirt and water is already connected to the plug connector of the plug connector arrangement. Thus, by engaging and fitting the unit or the whole onto the mating plug connector-component group, for example on the cover, it is advantageously possible to simultaneously contact a plurality of plug connectors with a plurality of mating plug connectors, which in turn reduces the assembly time. The accommodation of a plurality of plug connectors into the cover element is preferably effected in such a way that the cover element is connected to the respective housing of the plug connectors, in particular in a form-fitting or force-fitting manner. In this case, it can be provided that the individual plug connectors are arranged or fastened in a loss-proof manner, for example in the z-direction, on the cover element, but with a certain play. The connection of the individual plug connectors to the mating plug connector can thus advantageously be carried out not simultaneously, but in succession, in order to counteract high actuating forces which may occur in all plug connectors, for example when spring-open forces occur simultaneously. By means of the cover element, for example, a fixed relative positioning of the plug connectors in the x-direction and the y-direction with respect to one another can be brought about. In this case, it is also possible to fix other plug connectors, which are not provided with levers, in or on the cover element in their relative position with respect to the plug connector component group, in particular in the x-direction and the y-direction. The cover element has, for example, a latching element for latching the additional lever when it is in the latching position. The additional lever can therefore be held in the locked position, wherein an unintentional return of the additional lever into the release position is avoided. Since the additional lever also controls the other levers, this achieves that all other levers of the plug connector component group are likewise held in the locking position. A safe and reliable electrical contact between the plug connector and the mating plug connector is thereby achieved.

In a further development, it is provided that the receiving point, in addition to the relative rotation, also enables a relative movement between the lever and the connecting rail. The relative movement may be effected, for example, along the z-axis and/or along the y-axis. This advantageously allows tolerance compensation which prevents a bending of the connection rails if, for example, individual mating plug connectors are not arranged precisely at the same height in the z direction on the side of the mating plug connector.

In a further development, it is provided that the receiving point is formed by an elongated hole in the connecting rail. Advantageously, the pin of the lever or of the additional lever engages in the elongated hole. These elongate holes advantageously extend linearly along the z-axis or at an angle of between-30 ° and +30 ° to the z-axis or are curved with respect to the z-axis. The bending is thus effected in particular in the direction of the y-axis. In this case, during bending, the tangent at the start of the long hole makes an angle of, for example, at most 45 °, preferably at most 35 °, and most particularly preferably at most 25 °, with respect to the tangent at the end of the long hole. By means of the curved rails, in particular the individual levers or lever pairs can be moved offset in time from one another. Thus, not all levers or lever pairs are transferred simultaneously into the end position, but are spaced apart in time, whereby peaks are slowed down or avoided, in particular when an actuating force is applied. Furthermore, the length of the connecting track in the direction of the y-axis can be reduced by the curved extent of the elongated hole, wherein the same movement sequence of the lever and of the additional lever can nevertheless be achieved. Since a part of the displaceable movement of the lever is then achieved by the movement of the receiving point within the elongated hole, the connecting rail does not have to travel the entire displacement. In this way, the connection tracks can advantageously project only slightly in the y direction or not at all over the housing of the outermost plug connector.

In one refinement, it is provided that the elongated holes for each pair of levers arranged on the same housing have different geometries. As already described above, a pair of levers is understood to mean an arrangement of two levers which are arranged on the same housing, however, for example, on opposite sides to one another. The different geometries make it possible in particular to actuate these lever pairs at times determined by the geometries. The points in time at which the respective lever pairs are actuated can thereby be adjusted relative to one another. Furthermore, only a single movement of the actuating element is required, wherein the single movement enables the actuation of a single lever or lever pair at different times, i.e. in particular the transition from the starting position to the end position. In this way, the maximum value can be shifted in the case of the actuating force to be applied. This prevents peaks in the actuating force to be applied.

In one refinement, it is provided that the connecting rails each have at least one guide element. The guide elements are guided in a respective one of the mating guides of the cover element so as to be movable along the y-axis. The y-axis is oriented perpendicular to the x-axis and the z-axis.

The guide element advantageously prevents the connecting rail from tilting. This can, for example, substantially fix the movement of the connecting rail in the y direction, thereby preventing the connecting rail from moving in the z direction and thereby becoming hooked onto the housing or onto an element projecting from the housing. Furthermore, it is advantageously possible for the guide elements to counteract twisting of the additional lever or of the handle of the additional lever. When the additional lever is configured in a U shape, a cross member is present which extends between two lever arms which are each arranged on a connecting rail and which can be acted on by the assembly person. For example, if the assembler twists the additional lever on its handle, i.e.: one side of the lever will move further in the rotational direction than the other side and then the connecting rail will be displaced in the z-direction relative to the other connecting rail. The guide element limits this displacement and thus resists twisting of the attachment lever. In this way, tilting of the plug connector relative to the mating plug connector is advantageously also prevented by displacing the respective lever pair uniformly on both sides, for example from the starting position into the end position.

The invention also relates to a plug connector assembly. The plug connector assembly comprises a plug connector-component group as described above. Furthermore, the plug connector arrangement comprises a mating plug connector component group, wherein the mating plug connector component group has at least two mating plug connectors. The plug connector component group can be connected to a mating plug connector component group or can be plugged together with it. This means that the plug connector of the plug connector component group can be inserted into or onto the mating plug connector of the mating plug connector component group along the z-axis. The connection can be made by means of a lever. The mating plug connector has electrical mating contacts which can be brought into electrical contact with the electrical contacts of the plug connector component group. In particular, the electrical contact and the electrical mating contact make electrical contact when the plug connector is mated or connected with the mating plug connector and the connection of the plug connector with the mating plug connector is effected by the lever. Thus, a reliable electrical connection is produced, which can only be released when the lever is transferred to the starting position (in particular only when the lever is transferred to the starting position). In particular, unintentional release of the electrical connection is thereby avoided. Such plug connector assemblies are found, for example, in vehicles. The mating plug connector component group can be, for example, a mating plug connector of a control device of a vehicle, while the plug connectors of the plug connector component group are plug connectors of a cable harness of the vehicle.

Such a plug connector arrangement can be assembled particularly easily.

Detailed Description

Fig. 1 shows a plurality of plug connectors according to the prior art. This figure has already been described at the beginning.

Fig. 2 shows a schematic cross section through a plug connector arrangement 21, which is composed of a plug connector component group 1 and a mating plug connector component group 18. The plug connector assembly 1 is shown here in the unconnected state.

The plug connector component group 1 has a plurality of plug connectors 3, one of which is completely visible and the other of which is located on the right. Each plug connector 3 has a housing 2, wherein each plug connector 3 can be connected along the z-axis (here pointing downward from above) to a mating plug connector 18 of a mating plug connector component group 17 having at least two mating plug connectors 18. An electrical contact 19 for electrically contacting a mating contact 20 of the corresponding mating plug connector 18 is arranged in the interior of each housing 2. Here, one contact 19 each is shown as a female contact and a mating contact as a pin or contact blade. At least one lever 4 is arranged on each housing 2 of the plug connectors belonging to the plug connector component group 18, said lever being used to reduce the actuating force when connecting the plug connector to a corresponding mating plug connector. Each lever 4 is rotatably mounted on the associated housing 2 at a mounting point 10, wherein the lever 4 is displaceable or rotatable between a starting or first position and a final or second position. The actuating element 5, which also actually belongs to the plug connector component group 1, is not shown here for reasons of clarity. The lever is shown in its starting position in fig. 2.

The contacts 19 are connected to cables or lines, not shown here, which project upwards from the plug connector 3 in the drawing. In order to be able to avoid as far as possible the ingress of dirt, dirt and moisture or splashes, the plug connector has a cover 16. Cables not shown here extend to the left in the figure from the cover. In contrast to the U-shaped lever of a single plug connector, the plug connector component group also makes it possible to mount the cover 16 by rotating it by 180 °, so that the cable harness then projects to the right from the plug connector.

The lever 4 shown in the figures (on the opposite side, a further lever 4 can be formed, which forms a lever pair with the lever) extends through the housing 2 with an axis, which can lie on the lever axis of rotation, and has a gear 22 on the inside of the housing 2, which has only two teeth in this case. The gear wheel 22 can interact with a complementary element embodied as a toothed rack 23, which is arranged on the mating plug housing. The toothed rack is also arranged on the other side in mirror symmetry with respect to the z axis.

This also enables the lever 4 to be rotated by 180 ° to stop (in the starting position and then to point to the right) and the cover 16 to point in the other direction. The toothed rack 23 is embodied here with only one tooth. In principle, other force transmission structures between the lever and the mating plug connector are also conceivable, such as a sliding groove on the lever and a pin on the housing of the mating plug connector.

In particular, the levers 4 are mounted on opposite sides of the housing 2 along the x-axis. The x axis is an axis perpendicular to the z axis and is shown here from the plane of the drawing to the outside.

Fig. 3 shows the plug connector assembly 21 from fig. 2 in the connected state: the plug connection is now closed. The contact 19 is in mechanical and electrical contact with the counterpart contact 20. In order to establish this connection, the lever is displaced from its starting position into its end position by a counterclockwise rotation in the figure.

The mating plug connector component group 17 can be, for example, a connection region of a control unit. The plug connector component group 1 is, for example, a terminal of a cable harness. The plug connector assembly 21 can be used, for example, in a vehicle.

Fig. 4 schematically shows a part of a plug connector component group 1 according to a first exemplary embodiment of the present invention. In this case, four plug connectors 3 are provided, so that four lever pairs each having two levers 4 are provided. Fig. 4 omits a clear illustration of the housing 2 of the plug connector 3, and only the levers 4 are shown, which are each supported on the respective housing 2 at a support point 10. Furthermore, an actuating element 5 is provided.

In the first embodiment, the handling element 5 comprises 2 connecting rails 6 and one connecting element 9 connecting said connecting rails 6. In particular, the connecting rail 6 extends along the y-axis, while the connecting element 9 extends along the x-axis. As previously mentioned, the z-axis corresponds to the insertion direction. The x, y and z axes are oriented perpendicular to each other.

The actuating element 5 is thus substantially U-shaped. In particular, the actuating element 5 is formed in one piece, which is particularly advantageously an injection-molded part. This means in particular that the connecting rail 6 and the connecting element 9 cannot be released from one another without damage.

The levers 4 are all supported at a respective receiving point 11 on one of the connecting rails 6. Furthermore, such a bearing allows a relative rotation of the lever 4 and the connecting rail 6 about a rotational axis oriented parallel to the x-axis. If an actuating force is applied to the actuating element 5, for example to the connecting element 9, the translational movement 100 takes place along the y-axis. Additionally, a movement of the actuating element 5 along the z-axis is effected. By this movement of the actuating element 5, a transfer of the lever 4 from the starting position into the end position and vice versa takes place. Thus, only the actuating element 5 is actuated, wherein all levers 4 can be actuated thereby. In particular, a simultaneous transfer of all levers 4 from the starting position to the end position or vice versa takes place. This simplifies the assembly of the plug connector 3 on the mating plug connector 18.

Fig. 5 schematically shows a spatial representation of a plug connector component group 1 according to a first exemplary embodiment. In fig. 5, it is shown that the receiving point 11 is formed in that the connecting rail 6 has a circular opening into which the pin of the lever 4 engages. In this way, a form-locking or force-locking connection is present between the connecting rail 6 and the lever 4. By applying an actuating force to the actuating element 5, the levers 4 can therefore be moved simultaneously and reliably. The opening can have, for example, on its underside a slot which extends as far as the lower end of the connecting rail 6. In this way, the connecting rail can be pushed onto the receiving point 11, for example, from above, and then it locks in the opening, for example, in a circular shape. However, the opening can also be designed without such outwardly extending slits, and the receiving point 11 can be designed, for example, as a button-like element, so that the receiving point 11 can be clipped into the opening.

Fig. 6 schematically shows the plug connector component group 1 with the lever 4 in the starting position, while fig. 7 shows the plug connector component group 1 with the lever 4 in the end position. When the lever 4 and the actuating element 5 are transferred from the starting position shown in fig. 6 into the end position shown in fig. 7, the actuating element 5 must be moved along the y-axis. Thus, a manipulation force needs to be applied by the assembler substantially along the y-axis. The actuating element 5 projects with its outermost end in the y direction beyond the outermost end of the outermost plug connector housing 2 by the dimension a or the distance a or the projection a. When the end position of the lever 4 is reached, the actuating element can be arranged without a projection, viewed in the y direction, with respect to the outermost plug connector (see fig. 7).

Preferably, the plug connector 3 has a cover 16 on that side along the z-axis which is not provided for connection with the mating plug connector 18. The cover 16 serves to individually cover the individual plug connectors 3. Furthermore, it is provided that a latching element 15 is provided on at least one of the covers 16, wherein the latching element 15 serves to latch one of the levers 4 to the respective cover 16 when the levers 4 are arranged in the end position.

By actuating all levers 4 quickly and in particular simultaneously, the assembly effort can be significantly simplified. In particular, assembly time is reduced. Thus, even a large number of plug connectors 3 can be assembled in a simple and cost-effective manner.

It has been described throughout in connection with the first embodiment that all levers 4 are actuated simultaneously. However, the actuating element 5 can also be configured in such a way that during the movement of the actuating element the levers 4 are displaced successively through the same position. For example, the offset (Versatz) can be set such that only with increasing movement of actuating element 5 in the y-axis direction does some of levers 4 likewise be actuated, or not every plug connector 3 reaches the same z-position with respect to the corresponding mating plug connector at the same time.

Thus, it is possible, for example, to achieve that, in the case of three plug connectors 3 of a plug connector component group, the z position is not reached simultaneously with the highest plug force for all three plug connectors 3, but is reached, for example, first by the first plug connector, then by the second plug connector after the maximum plug force of the first plug connector is exceeded, and then by the third plug connector after the maximum plug force of the second plug connector is exceeded. The actuating force to be applied can thus be varied and reduced, in particular, in respect of the maximum variable. This can be achieved by a suitable design of the connecting rail 6: in other words, the structures formed specifically on the connecting rails 6 can be shifted in time in the y direction and/or in the z direction when the same z position of the respective plug connector is reached. It can be understood that at the end of the movement of the actuating element, all plug connectors are reliably connected and electrically contacted to the corresponding mating plug connector.

Fig. 8 schematically shows a part of a plug connector component group 1 according to a second exemplary embodiment of the present invention. The illustration of the housing 2 is omitted again.

Unlike the first embodiment, there are two separate connecting rails 6. These connecting rails 6 are not connected by a connecting element 9 as in the first embodiment. Instead, the connecting rail 6 remains as a completely separate component.

One of the lever pairs of the levers 4 of the same plug connector 3 is designed as a substantially U-shaped additional lever 7. The additional lever 7 projects beyond the other levers 4 and serves to actuate the entire actuating element 5. In the second exemplary embodiment shown in fig. 8, the actuating element 5 is therefore composed of an additional lever 7 and two connecting rails 6. In order to transfer the levers 4 and the additional levers 7 from the starting position into the end position, the fitter must therefore perform substantially the same rotational movement 200 on the additional levers 7, which rotational movement is performed in the prior art on each lever 4. Due to the fact that the additional lever 7 protrudes beyond the other levers 4, a reduced operating force needs to be applied to the additional lever 7. Therefore, the length of the additional lever 7 is extended. The length of the additional lever 7 is determined as the distance between the bearing point 10 and the point of the lever 7 having the greatest distance to the bearing point 10 in the y-z plane. In particular, the length is configured such that the additional lever 7 projects beyond the cover 16 which is present. In this case, the additional lever projects beyond the cover 16, in particular in any position between the starting position and the end position. The additional lever 7 can have a length L which is at least 20%, preferably at least 40%, particularly preferably at least 60%, and very particularly preferably at least 100% longer than the length of the lever 4 (double the length of the lever 4).

Fig. 9 shows a spatial representation of a plug connector component group 1 according to a second exemplary embodiment, wherein the lever 4 and the additional lever 7 are arranged in a starting position. Fig. 10 shows the same component group 1 in a state in which the lever 4 and the additional lever 7 are arranged in the end position.

In the second exemplary embodiment, it is also preferably provided that the plug connector component group 1 has a cover element 8. The cover element 8 replaces all the covers 16, so that only one single element is provided as cover element 8. This element can be fitted onto the housing 2 of a single plug connector 3. The housing 2 can be arranged in a loss-proof manner on the cover element 8. The housings 2 may for example be fixed relative to each other in the x-direction and/or the y-direction with respect to their relative position. The housing 2 can be fastened to the cover element 8, for example, in a form-fitting or force-fitting manner, but in particular a certain play can be provided in the z direction as a tolerance compensation during assembly and in order to be able to realize different steps of the same z position of the plug connector (durchreset). The plug connectors 3 can therefore be prefabricated by attaching them to the cover element 8, so that all plug connectors 3 can be connected as a unit to the mating plug connector 18.

The additional lever 7 projects beyond the other levers 4, as already explained above. This is provided in particular by the additional lever 7 being arranged above the cover element 8 in the terminal position in the z direction. In contrast to the exemplary embodiment of fig. 5 to 7, the actuating force can be further reduced by the upward extension of the additional lever 7. Since, in the end position of lever 4, actuating element 5 (fig. 5 to 7) should not collide with cover element 8 when cover element 8 is already fitted, the interference dimensions of the solution with actuating element 5 cannot be reduced due to the design.

Since the additional lever 7 does not have to be arranged on the outermost plug connector 3, the interference dimension B is smaller than the interference dimension a required when the forces in fig. 5 to 7 are reduced in the same way, despite the reduction in the actuating force. In fig. 9, it can be seen that the interference dimension C of the connecting rail 6 is smaller than the interference dimension B of the additional lever 7. However, if the additional lever 7 is still fitted to the left again, the interference dimension of the additional lever 7 is no longer present at all. The design with the additional lever therefore offers the possibility of reducing the interference dimensions and at the same time reducing the operating forces by means of a longer lever arm. Furthermore, the additional lever 7 can be arranged such that it always projects beyond the cover element 8 and can thus keep the interference dimensions small compared to the embodiment with the actuating element 5 (fig. 5 to 7).

In particular, locking with the catch element 15 of the cover element 8 is achieved if the additional lever 7 is arranged in the end position shown in fig. 10 (see also the detail section in fig. 11). The latching element 15 prevents the additional lever 7 from returning to the starting position. A safe and reliable electrical and mechanical connection between the plug connector component group 1 and the mating plug connector component group 17 is thus achieved.

Fig. 12 shows a schematic illustration of a plug connector component group 1 according to a third exemplary embodiment of the invention. In this case, four plug connectors 3 are shown in a side view, which are coupled to one another by means of the cover element 8 or are fixed in their relative position with respect to one another at least in the x-direction and in the y-direction. The whole consisting of the cover element 8 and the four plug connectors 3 is therefore prefabricated and can be fitted, for example, as a separate unit onto an assembly consisting of four mating plug connectors. At the left end of the cover element 8, it projects slightly beyond the outermost contour of the plug connector 3 on the left outer side. In this region, the cable bundle can leave the cover element 8 or project therefrom. The cable bundle may be formed by four separate cable bundles of the plug connector 3.

Two of the plug connectors 3 (first and third plug connectors 3 viewed from the left) have levers 4 on their housings (each of which can be arranged with the other lever 4 on the opposite side, which is not visible here). Every two levers 4 on both sides are mutually coupled through a connecting track 6. The lever pair on the right in the figure is configured as an additional lever 7. When the additional lever 7 is actuated, it can be displaced from its starting position (in this case pointing to the right) into its end position (in this case pointing to the left). It will be appreciated that the start and end positions may be interchanged. Here, the other lever pair is also displaced together by the connecting rail 6 (shown in dashed lines). If the whole is fitted onto the mating plug connector, the plug connection can also be closed by a movement of the additional lever 7 in a single direction (plug connector 3 and mating plug connector then move towards each other in the z direction, as described above). By coupling two plug connectors 3 which are not provided with levers to two plug connectors 3 which are provided with levers 4 by means of the cover element 8, it is advantageously possible to establish a connection of all four plug connectors 3 to the respective mating plug connector. Then, a plug force is applied to the plug connector 3, which is not provided with a lever, by means of the cover element 8. In this way, additional savings can be made in terms of components (levers of the two plug connectors 3). It may be necessary to dimension the force transmission structures, such as the gear elements and the toothed racks, on the lever 4 and on the mating plug connector accordingly in order to be able to absorb the plug force of more than one plug connector 3.

Furthermore, the additional lever 7 projects beyond the cover element 8 in any position. The cover element 8 can thus in principle be fitted in any direction, i.e. with cable harness outlet to the left or to the right. This advantageously increases the flexibility in mounting the whole. Since, by means of this flexibility, it is not necessary to change the lever engagement geometry when rotating the cover element 8, the additional lever is simply pivoted by the rotating cover element 8.

In fig. 12, furthermore, at least one latching element 15 is provided in each case for both the starting position and the end position in order to prevent the additional lever 7 from being unintentionally displaced in its respective extreme position.

In fig. 12, a plug connector assembly 1 is formed by two plug connectors 3 provided with levers 4 or additional levers 7. The further plug connector is here a component of the plug connector unit (which here includes the cover element 8), but not of the plug connector component group.

Fig. 13a and 13b and fig. 13c and 13d show schematic views of a part of a plug connector component group 1 according to a further exemplary embodiment of the present invention. In this case, one outer end (here the right end) of the connecting rail 6 is shown, which has a respective receiving point 11 for different positions of the lever 4 or of the additional lever 7 associated with the receiving point 11. The initial position is correspondingly shown at the far right (solid line); one or more other locations are shown in different dashed lines.

In this exemplary embodiment, provision is made for the levers 4 and the additional levers 7 to be connected to the respective connecting rails 6 at the receiving point 11, and in addition to the relative rotation, a relative translation between the additional levers 7 and the connecting rails 6 and between the levers 4 and the connecting rails 6 is also possible. Here, relative translation is performed along the z-axis. This advantageously enables the additional lever 7 and the decoupling of the direction of movement of the lever 4 and the connecting rail 6. This can result in the connecting rail being moved as far as possible in the y direction, while the lever 4 and the additional lever 7 perform a rotational movement. Thereby preventing tilting. Furthermore, tolerance compensation in the z direction can be achieved if, for example, the mating plug connectors are not all arranged in their nominal position in the z direction. If a plurality of plug connectors 3 (for example more than 3) are connected simultaneously to the mating plug connector, the connecting rails 6 or the actuating element 5 can thereby be bent without the elongated holes.

This possibility of relative movement along the z-axis is achieved in that the receiving point 11 is formed by an elongated hole 12 in the connecting rail 6. Advantageously, the pins of the lever 4 and of the additional lever 7 engage in said elongated hole 12, so that in addition the relative rotation about the axis of rotation parallel to the x-axis described above is also possible.

The elongated hole 12 may extend along the z-axis (fig. 13a and 13 b). Likewise, the slot may extend at an angle of, for example, between-30 ° and +30 ° with respect to the z-axis.

Finally, it is also possible to provide the curvature of the slot 12 (fig. 13c and 13 d) in such a way that the slot is advantageously curved in any direction of the y-axis, for example up to 30 ° (angle between the tangent at the end of the slot and the tangent at the beginning of the slot).

In fig. 13b, the spacing E represents the extent to which the connecting track is displaced in the y-direction when the lever 4 or the additional lever 7 is displaced by means of the rotary movement 200 from a first position (e.g. starting position) to a second position (e.g. end position). In this rotational movement 200, the receiving point 11 moves from the lower end of the elongated hole 12 to the upper end of the elongated hole 12.

As a result of the bending shown in fig. 13c and 13D, during the actuation process of lever 4 or additional lever 7, distance D can be smaller (fig. 13c, in which long hole 12 bends to the left or along rotational movement 200) or larger (fig. 13D, in which long hole 12 bends to the right or counter to rotational movement 200) than distance E in the case of a linearly extending long hole 12 (fig. 13 b).

The design of the long holes 12 as in fig. 13c (bending to the left or along the rotational movement 200) results in a shorter displacement D compared to the spacing E of the straight long holes 12 in fig. 13 b. This allows the connecting rail 6 to be designed shorter, since a part of the displacement is now produced in the y-direction by the displacement inside the connecting rail 6. This saves installation space in the y direction, since during the transition of the lever 4 from the starting position to the end position or from the end position to the starting position, the entire actuating element 5 or the connecting rail 6 executes a reduced movement and therefore requires less installation space. The shorter displacement is accompanied by an increase in the force to be expended at the lever 4 or the additional lever 7.

The design of the long holes 12 as in fig. 13D (bending to the right or against the rotational movement 200) leads to a longer displacement D than the spacing E of the straight long holes 12 in fig. 13 b. In this way, it is nevertheless necessary to design the connecting rail 6 to be longer. However, this also results in a reduction of the force to be expended at the lever 4 or the additional lever 7. Thus, for example, the length of lever 4 or additional lever 7 can be shorter and thus the projection of lever 4 or additional lever 7 in the y direction beyond cover element 8 can be smaller for the same actuating force requirement.

The necessary actuating force and the necessary projection in the y direction can therefore be optimized by the shape of the elongated hole 12, depending on the given conditions on the construction or the current installation situation.

Provision can be made for the connecting rail 6 to be guided on the cover element 8. This is achieved in that each connecting track has at least one guide element 13, which is guided displaceably along the y axis in a respective one of the counter-guides of the cover element 8. Tilting of the connecting rail 6 is avoided in particular by the guide element 13 and the counter guide 14. Thus, a reliable movement of the actuating element 5 can be achieved.

As a result, as linear as possible a guidance of the actuating element 5 or of the connecting rail 6 in the y direction is possible even if the lever 4 is subjected to a rotational movement.

Fig. 14 schematically shows a plug connector component group 1 according to a further exemplary embodiment, with the lever 4 and the additional lever 7 in the starting position.

Fig. 15 shows the same spatial representation as fig. 14 from a different perspective.

This embodiment therefore differs from the second embodiment (fig. 9 to 11) only in that elongated holes 12 are present, wherein the connecting rail 6 additionally has guide elements 13 by means of which the connecting rail 6 is guided in mating guide portions 14 of the cover element 8. This, in addition to reducing the installation space required for the movement of the actuating element 5, also leads to a simplified actuation of the actuating element 5, since tilting is prevented in particular. Therefore, damage due to such tilting can also be avoided. Furthermore, tolerance compensation with respect to the mating plug connector can be achieved.

Fig. 16 shows a different lever type for the actuating element 5. The lever 4 is therefore shown, which extends only between the bearing point 10 and the receiving point 11. The lever 4 is used to reduce an operating force when connecting the plug connector 3 and the mating plug connector 18. Furthermore, an additional lever 7 is shown, which is produced by applying a sleeve 7a to the previously described lever 4. The additional lever 7 is thus longer than the lever 4, whereby the additional lever 7 projects beyond the lever 4. In addition to the function of the lever 4, the additional lever 7 has the function that an actuating force can be applied to it in order to move the actuating element 5. Furthermore, the lever pair can be coupled by the sleeve. The additional lever 7 can be designed to be adjustable over its length in such a way that the attachment 7a is adjustable relative to the lever 4.

Finally, fig. 16 shows an integrally formed additional lever 7. This additional lever 7 has the same function as the previously described additional lever 7, but is not adjustable in its length.

Finally, fig. 17 shows a sleeve 7a for producing the additional lever 7.

The sleeve portion 7a can also advantageously vary in its width, which is illustrated in fig. 17 by two exemplary different widths, namely a first width F and a second width G.

The assembly process of the plug connector-component group 1 is advantageously carried out as follows: first, the housings 2 of the plug connectors 3 are arranged side by side. Then, the levers 4 are mounted on the respective housings 2. This is achieved, for example, by a cardholder. If an integrated additional lever 7 is present, it is also mounted on the respective housing 2, in particular by clipping. Subsequently, the connecting rail 6 is mounted on the lever 4 and the additional lever 7. This is again achieved by the cardholder. If the additional lever 7 is produced by means of the sleeve 7a, this step can be carried out before or after the assembly of the connecting rail 6. Finally, the cover element 8 is fitted. The plug connector component group 1 is therefore completely preassembled and can be transported as a unit.

Furthermore, the following assembly sequence can also be implemented: the plug connectors 3 are positioned relative to each other. The plug connectors 3 are connected to one another in a loss-proof manner, for example, by the cover element 8, but other couplings can also be realized, for example, by connecting elements on the housing 2. At least two lever pairs are mounted on at least two plug connectors 3. If necessary, one of the lever pairs is designed as a (longer) additional lever 7. The actuating element 5 or the connecting rail 6 is mounted on the receiving point 11. Either corresponding to the plug connector component group 1 or a prefabricated whole which can have such a plug connector component group 1 can then be arranged on a mating plug connector 18 of a mating plug connector component group 17 and connected thereto by actuating the actuating element 5.

If a plug connector arrangement is to be assembled, a pre-assembled plug connector arrangement 1 is provided. Furthermore, it is achieved that a mating plug connector component group is provided, which is, for example, an interface on a control unit of a vehicle. The plug connector component group 1 is placed on the mating plug connector component group 17. The lever 4 and the additional lever 7 thereby engage in complementarily shaped mating elements of the mating plug connector 18 of the mating plug connector component group 17. By moving the actuating element 5 in one direction, all levers 4 and the additional levers 7 are transferred into the end position. In addition, a relative movement between the plug connector 3 and the mating plug connector 18 along the Z-axis occurs, so that a safe and reliable electrical and mechanical connection exists between the plug connector component group 1 and the mating plug connector component group 17. If the additional lever 7 is made by means of a sleeve 7a, this sleeve 7a can be removed as a final step.

The plug connector component group 1 makes it possible to mount a plurality of plug connectors on a mating plug connector in a simple and cost-effective manner, with low assembly costs and short assembly times. In this case, only a single element, i.e. actuating element 5, needs to be moved in a single direction. Thus, the number of assembly steps required is minimized.
