  • the line bus consists of a CAN bus to the interfaces forming plug-in contacts said modules are plugged. It is thus possible in a cost effective and simple manner to arrange the display and / or operating module at different locations, which are designed with plug-in connections on the motor vehicle in order to control the attachable additional units.
  • the disadvantage here is that when a malfunction of the bus diagnostic data can no longer be issued and a resolution of the node is required.

  • the data bus is replaced by a Data bus coupling extended from the towing vehicle in the tracking vehicle.
  • the actual hubs are located in the towing vehicle or in the trailing vehicle.
  • One data bus is provided with a first plug-in device and the other extended part of the data bus is provided with a second plug-in device. The contact is made by putting the two connectors together.
  • the disadvantage here, however, is that when pulling the plug, the cables of the data bus can be damaged.
  • the critical, conventional nodes remain unchanged in such an arrangement.
  • a CAN bus essentially consists of a ring line to which the CAN stations are connected via a line crimp or can be closed. Such a Budapest period for the CAN subscribers and the different transmission speeds, for example in the comfort CAN, drive CAN, display CAN, a variety of such crimp connections are provided in the motor vehicle, which are integrated in the cable harness (harness) and either under the carpet, behind panels or are arranged in the dash panel area of the motor vehicle.
  • the object of the invention is therefore to implement a CAN bus system for a motor vehicle and in particular a node such that a simple error analysis is possible and that the safety of the electrical connection is ensured.

  • such a node is positioned at a location in the motor vehicle, which allows easy access, in particular for error analysis.
  • a place in the area of the instrument panel is suitable for this purpose. But are also more suitable places, for example in the engine compartment or in the trunk, if this seems more appropriate.
  • several nodes can be provided in the motor vehicle, for example, node points on the left and right sides of the dashboard can be arranged in the footwell.
  • the first part 1 has a housing 4 for receiving a contact carrier 5, to which at least one line of the bus system can be connected.
  • This contact carrier 5 can be inserted for example in a recess 6 on the housing 4 and rest in an end position.
  • the housing 4 of the first part 1 can be introduced for attachment in an opening of the motor vehicle and snap there in an end position.
