Definitions
- DE 195 05 845 A1 discloses a control device for operating additional units located and / or attachable, in particular for municipal or winter services, and in particular in the form of a control unit, with a control, display and operating module via one the line bus provided for the vehicle are connected.
- the cable bus consists of a CAN bus, to which plug-in contacts forming interfaces can be plugged in. It is thus possible in a cost-effective and simple manner to arrange the display and / or operating module on the motor vehicle at different points which are designed with plug connections, in order to control the attachable additional units.
- Such a CAN bus essentially consists of a ring line to which the CAN participants are connected or can be closed via a line crimp. Such a cable crimp can no longer be separated or can only be separated with considerable effort. Chwindier due to the many CAN node and the different admiratsgäs', for example in the comfort CAN, drive CAN, display CAN, are provided such crimped connections in the motor vehicle a plurality, which are integrated in the cable wiring harness (wiring harness) and either under the carpet, are arranged behind panels or in the dash panel area of the motor vehicle.
- the object of the invention is therefore to design a CAN bus for a motor vehicle and in particular a node in such a way that a simple error analysis is possible and that the security of the electrical connection is ensured.
- the advantage of the invention is that the node is formed by a first part to which the at least one line of the CAN bus is routed and a second part that can be joined to the first part and has means for connecting the line. It is thus possible to form a CAN node in a simple manner by joining the first and second parts. By separating the parts, this CAN node can be easily resolved to make it accessible for error analysis. For the error analysis, for example, an analyzer can then be connected to the CAN bus via a line on which a second part is provided at the end.
- FIG. 1 shows a node of a data bus for a motor vehicle according to the invention
- FIG. 2 shows parts of the node according to FIG. 1,
- FIG. 3 shows a first part of the node
- FIG. 4 shows a second part of the node in a top view
- Figure 5 shows the second part in a bottom view
- connection device for a fault analysis device shows a connection device for a fault analysis device
- FIGS. 7-10 basic representations of the node according to FIG. 1.
- FIG. 1 shows an exemplary embodiment of a node of a data bus, for example a CAN bus for a motor vehicle, which has a first part 1 to which at least one line, ie the line ends of the line of the CAN bus, can be routed.
- a second part 2 of this node can be joined together with the first part 1 and has means for connecting the line ends.
- the first part 1 is designed as a plug socket and the second part 2 as a plug.
- the first part 1 could also be designed as a plug and the second part 2 as a plug socket.
- the second part 2 can be locked on the first part 1 via a locking element 3. The node is thus secured against unintentional opening.
- Such a node is particularly preferably positioned at a location in the motor vehicle that enables easy access, in particular for error analysis.
- a location in the area of the dashboard is suitable for this, for example.
- other places are also suitable, for example in the engine compartment or in the trunk, if this seems more appropriate.
- several nodes can also be provided in the motor vehicle, for example nodes can be arranged on the left and right sides of the dashboard in the footwell.
- This contact carrier 5 can be inserted, for example, into a recess 6 on the housing 4 and can rest in an end position.
- the housing 4 of the first part 1 can be inserted into an opening of the motor vehicle for fastening and can rest there in an end position.
- This embodiment has advantages in production, since this type of fastening is associated with a short expenditure of time.
- the housing 4 of the first part 1 could also be fastened to the motor vehicle via a screw connection or snap connection.
- the second part 2 is designed as a connector 7 and has at least one two-pole short-circuit bridge 8.
- a plurality of short-circuit bridges 8 can be received by the connector 7, two eight-pole and two sixteen-pole short-circuit bridges 8 being provided, for example.
- this short-circuit bridge 8 or these short-circuit bridges 8 connects one line or several lines which are led to the contact carrier 5 and are / are assigned to a CAN bus of the motor vehicle.
- the locking element 3 comprises a lever 9 which can be attached to the plug 7 and which can be pivoted about the pin bearing 10 provided on the plug 7.
- the journal bearings 10 are received in openings 11 which are provided on the legs 12 of the lever 9.
- a tooth 13 is formed at least on one leg 12, which interacts with a tooth or a tooth receptacle 14 formed on the housing 4 for effecting the locking.
- the lever 9 can be pivoted about the journal bearing 10 from the position shown in FIG. 4, so that it engages in a position shown in FIG. 1 on a latching element 15. It also follows from FIG. 4 that the plug 7 has a coding area 16 has, so that it can only be assigned to a specific plug socket in a specific assignment (FIG.
- the contact carrier 5 has a plurality of regions 17, to which a common or else a bus system can be assigned. It can also be seen that the contact carrier 5 is designed with positioning recesses 18 and can engage in the positioning pins 19 of the plug 7 (FIG. 5).
- first and second parts 1, 2 are assigned a further latching connection 20, which is designed, for example, as a latching nose 22 which engages in a latching recess 21.
- an error analyzer can be connected to the first part 1 via an assigned line 23 and a further connector 24, so that signals can be coupled in and out.
- the error analyzer could be designed as a programming device, so that programming of at least one subscriber, for example a control unit, can be carried out in a simple manner via line 23 in connection with the further plug 24. From FIG. 6 it can be seen that also the further connector 24 is designed with a further lever 25 so that it can be securely attached to the first part 1.
- an L-shaped guide 26 can be formed on the connector 7 as well as on the first part 1, which in cooperation ensure in particular that the housing 4 of the first part 1 is held together on the connector 7. A bending of the housing 4 when it is assembled with the plug 7 is thus effectively counteracted. Equal effects are a matter of course T-shaped guides and Z-shaped guides short, guides that ensure a secure assembly and holding.
- FIGS. 7-10 show a basic node of a data bus, elements already mentioned having the same reference numbers in the following explanation.
- a basic node emerges from FIG. 7, at least one line 27 of a data bus leading to the first part 1.
- the second part 2 has an electrical or optical connection via which the line 27 is closed when the parts 1, 2 are plugged together. When the parts 1, 2 are removed, this line 27 is interrupted, i.e. opened.
- the line 27 of the data bus can be designed as an electrical or optical line. A line 27 of the data bus can thus be opened or closed in a simple manner by means of a node configured in this way.
- FIG. 8 shows that bus participants 28, 29, 30 are led to the first part 1 via at least one line in each case.
- the node is opened by separating parts 1, 2. It also follows from FIG. 8 that line 27 is also brought to the first part in this case, but this is not absolutely necessary. Within the scope of the invention, it is consequently also possible to route only bus users 28, 29, 30 to the node.
- a node corresponding to FIG. 8 results from FIG. 9.
- the second part 2 is removed from the first part 1 and a diagnostic connector 31 is connected to the first part 1.
- a diagnostic device 32 can be connected to the bus subscribers 28, 29, 30 via the diagnostic connector 31 and corresponding lines, so that these and possibly the line 27 can be diagnosed.
