Description

[0001] The invention relates to a control device arrangement according to the preamble of claim 1.

[0002] Motor vehicles have a large number of control units that can be connected to each other via connecting cables.

[0003] If the control units are located in different rooms, the connecting cables must be routed through partition walls via grommets. Depending on the complexity, existing solutions may involve multiple connectors, including screw-connected power supply cables. The connecting cables must be routed according to the spatial conditions.

The contact tongue of the first contact element is contacted by a conductor foil of the first electronic assembly, and the contact tongue of the second contact element is contacted by a conductor foil of the second electronic assembly.In a contact pair, the contact pin of the contact element of the first electronic assembly is connected to the contact socket of the contact element of the second electronic assembly.

[0005] The invention is based on the object of specifying a novel control device arrangement.

[0006] The object is achieved according to the invention by a control device arrangement having the features of claim 1.

[0007] Advantageous embodiments of the invention are the subject of the subclaims.

[0008] A control unit arrangement comprising a first control unit and a second control unit is proposed, each of the control units having a housing in which at least one printed circuit board is arranged. According to the invention, the control units are arranged on opposite sides of a partition wall having an opening, in particular in different rooms. Each of the control units has at least one direct plug-in connector contacted with the printed circuit board, which is guided or accessible through an opening in a rear side of the respective housing, wherein at least one of the plug-in connectors of one of the control units is guided through the opening and forms a plug-in connection with one of the plug-in connectors of the other control unit.

[0009] In one embodiment, at least the second control device has a collar on the rear side leading around the cutout, which collar has a contour that is complementary to a contour of the opening in the partition wall.

[0010] In one embodiment, at least one sealing ring is arranged around the collar on the outside and / or on the collar for sealing against the opening and / or for sealing against the rear side of the other control device.

[0011] In one embodiment, one, two, or more screw bolts are arranged within an area surrounded by the collar, each of which is provided with a thread and is in contact with the circuit board. The screw bolts protrude from the rear side beyond the collar.

[0012] In one embodiment, the first control unit has one, two or more feedthroughs between the rear side and a front side for at least partially passing through one of the screw bolts, wherein the feedthroughs are each aligned with one of the screw bolts in a mounting position and these each contact the circuit board of the first control unit.

[0013] In one embodiment, a respective nut is provided for establishing or securing a mechanical and electrical connection of the screw bolt to the circuit board of the first control unit, wherein the nut is accessible through the respective passage from the front of the first control unit.

[0014] In one embodiment, a respective plug is arranged in the feedthrough from the front side in order to seal it against moisture.

[0015] In one embodiment, the partition wall has one or more screw bases for fastening at least one of the control devices by means of a respective screw.

[0016] In one embodiment, the contour of the opening corresponds to or resembles an oval, a circular shape, a square, a rectangle, a trapezoid or an irregular quadrilateral or polygon, in particular with rounded corners.

[0017] In one embodiment, the connector is arranged on the circuit board of the respective control unit.

[0018] The control unit arrangement can be part of a motor vehicle, in particular a passenger car, a commercial vehicle, or a bus. The motor vehicle can have at least one electric drive motor and / or at least one internal combustion engine.

[0019] The inventive solution enables direct contact between the control units to be connected. This involves direct plug-in connections between the circuit boards. This requires that the control units are positioned back-to-back on the wall separating them.

[0020] The solution according to the invention eliminates a significant number of plug and screw connections on the control units. Furthermore, cable harnesses can be eliminated to a certain extent. Furthermore, assembly risks due to unplugged connections are reduced.

[0021] Embodiments of the invention are explained in more detail below with reference to a drawing.

[0022] Showing: Fig. 1 is a schematic view of two control units arranged in different rooms separated by a partition wall, Fig. 2 a schematic view of a rear side of one of the control units, and Fig. 3 a schematic view of the control units arranged on the partition wall.

[0030] Furthermore, one, two, or more screw bolts 18, each provided with a thread, can be arranged, particularly within the collar 17. The screw bolts 18 can be contacted with the circuit board 11, for example, such that one of the screw bolts 18 can be used as a positive pole and another screw bolt 18 as a negative pole or as redundancy in an on-board electrical system.

[0031] The first control unit 1 can have one, two, or more bushings 22 between the rear side 7 and the front side 14 for passing through one of the screw bolts 18 each, wherein the bushings 22 are each aligned with one of the screw bolts 18 of the second control unit 2 in an assembly position, wherein the screw bolt 18 contacts the circuit board 10 of the first control unit 1. A mechanical and electrical connection of the screw bolt 18 to the circuit board 10 can be established and / or secured by means of a nut 21, which is accessible through the respective bushing 22 from the front side 14. Furthermore, a respective plug 23 can be arranged in each of the bushings 22 from the front side 14 in order to seal them against moisture.
