The right and left sides of the wire harness from the branching portion may be the same length. The left and right pretensioners and the connectors connected to the side airbags may be the same. For this reason, if the wire harness is twisted between the controller and the branching portion or at the branching portion and is connected to the left and right sides, the operation does not match the impact, and the condition is poor.

If the left and right connectors of the wire harness are changed, it is necessary to prepare different connector connecting portions for the pretensioner and the side airbag, and it becomes impossible to share the left and right pretensioners and the side airbag. Significantly higher manufacturing costs.

By changing the color of the tape around which the wire harness is wound from the left and right branch portions of the wire harness, attention can be given not to assemble the wire harness in a reversed manner during assembly. However, even in this case, since it is not impossible to assemble in reverse, complete erroneous assembling cannot be prevented.

In order to achieve the above object, an apparatus for preventing incorrect assembly of a wire harness for an automobile according to the present invention has a controller provided in the center of a vehicle body, and a wire harness from the controller is left and right at a cross member portion. Branch, and route it along the rear wall of the cross member, wire it to the left and right side airbags and the pretensioner of the seat belt, and attach the wire harness to the wall of the left and right cross members with the mounting hole of the cross member. This is because the clamps of the wire harness have different shapes on the left and right.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIGS. A controller 1 for detecting an impact is mounted between the driver's seat and the passenger's seat in the center of the vehicle body, and arranged so that the controller 1 in the center of the vehicle body can uniformly detect an impact from any direction. The wiring harness 2 is wired from the controller 1 to the rear side, and the wiring harness 2 is branched right and left at the cross member 3 on the rear side of the driver's seat and the passenger's seat. Wire harness 2 branched right and left
Are fixed by fitting them into mounting holes 6, 7 formed in the rear wall of the cross member 3 with clamps 4, 5 mounted on the wire harness 2. Connectors 8 and 9 are provided on each of the left and right wiring harnesses. The connectors 8 and 9 are connected to a side airbag, and the connector 9 is connected to a seat belt pretensioner 10. When the controller 1 detects a certain impact or more, the side airbag is inflated, and the seat belt is urgently locked by the pretensioner 10.

The clamps 4 and 5 attached to the rear side of the branch portion of the wire harness 2 are such that the right clamp 4 has a conical fitting shape, and the mounting hole 6 of the cross member 3 is formed in a circular shape in accordance with the shape. The clamp 5 on the left has a square pyramid fitting shape, and the mounting hole 7 of the cross member 3 is a square hole. The wire harness 2 has the same length on the left and right sides from the branch portion, and the connectors 8 and 9 have the same length on the left and right.

When the wire harness 2 is twisted up to the branch portion, the right and left sides of the rear side from the branch portion are the same, so that the left and right sides are easily mistaken. However, the right clamp 4 can be fitted only into the right mounting hole 6 of the cross member 3, and the left clamp 5 can be fitted only into the mounting hole 7 of the left cross member 3. in this way,
Clamps 4, 5 on the rear side from the branch portion of the wire harness 2
And the shape of the mounting holes 6 and 7 of the cross member 3 are different, so that the left and right lengths and the connectors 8 and 9 are the same from the branch portion of the wire harness 2 to the rear side. There is no mistake in assembling.

Since the clamps 4 and 5 are sequentially assembled from the inside to the outside, it is not necessary to make the left and right shapes different from each other. Further, since the mounting holes 6 and 7 of the cross member 3 are provided on the rear wall of the cross member 3, the wire harness 2 can be prevented from protruding above the cross member 3.

As described above, since the present invention is constructed as described above, the shape of the clamp for fixing the cross member to the rear side from the branch portion of the wire harness is different from the shape of the mounting hole for the cross member. Therefore, if the clamp and the mounting hole do not match, assembly cannot be performed, and erroneous assembly of the left and right wire harnesses can be reliably prevented. Then, the length and the connector from the branch portion of the wire harness to the rear side may be the same, and the left and right side airbags and the connector connecting portion of the pretensioner can be shared, so that the productivity is good and the cost can be reduced. It should be noted that it is sufficient that the left and right shapes of the clamp and the mounting hole are different from each other at only one location inside, and if the wire harness is fixed to the rear wall of the cross member, the wire harness runs along the upper surface of the cross member. You can not.
