Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness composed of a plurality of electric wires, a manufacturing method for manufacturing the wire harness, and a manufacturing jig for manufacturing the wire harness.

[0002]

2. Description of the Related Art The wire harness described in Japanese Utility Model Laid-Open No. 56-161736 is formed by bundling a plurality of electric wires passing through the same route. These multiple wires are
It consists of various electric wires such as power supply line, signal line, and ground line. Such electric wires are arranged one by one along a predetermined path on the wiring stand, and finally bundled by tape winding or the like to manufacture a wire harness. When the wires are arranged on the wiring stand, it is not possible to specify which wire is located inside or outside because the wires are arranged randomly. Therefore, an important electric wire such as a power supply wire may be located outside. In such a case, the power line may interfere with the edge part of the vehicle body or other devices when it is attached to the vehicle body.Therefore, by installing a protector or tube on the wire harness, Protects the wires from interference with equipment. For this reason, the number of parts constituting the wire harness increases, and the manufacturing cost of the wire harness is high.

Therefore, Japanese Patent Laid-Open No. 6-275134
Japanese Unexamined Patent Publication No. Hei 7-130236, Open Technique 95-979
In No. 0, a wire harness that protects a specific electric wire by bringing the specific electric wire that seems to be important to the center of the wire harness and surrounding the specific electric wire with the other electric wire is provided. Proposed. In this wire harness, a specific electric wire can be protected without using a protector or a tube which has been required up to now, so that the manufacturing cost can be reduced.

[0004]

However, when a tape winding operation is performed to bundle a plurality of electric wires, the tape winding operation causes a twist in the entire wire harness, so that a specific electric wire is arranged at a specific position. It is a very difficult work to wind the tape in this state. That is, it is not possible to easily determine whether or not the wire harness is twisted unless the wire harness is checked after the tape winding work is completed, so it is not possible to perform the tape winding work so that the twist does not occur. It will be a difficult task. Further, if the tape winding work is carefully performed so that the twisting does not occur, the tape winding work takes time and the workability is poor.

On the other hand, even if the tape can be wound on the wire harness without being twisted, when the wire harness is mounted on the vehicle body panel, the wire harness is twisted and the workability of mounting the wire harness on the vehicle body is deteriorated.

That is, an example is shown in FIG. 7, in which a wire harness 4 in which a tape is wound without twisting and clips 1, 2 and 3 for attachment to a vehicle body are mounted in the same direction is attached to a vehicle body panel. When assembling to 5, the wire harness 4 is inserted into one hole 6 and then the wire harness is inserted into the other hole 7 so that the three clips 1, 2 and 3 are inserted from the hole 6 side as an assembling procedure. The clips 1, 2, 3 are inserted and engaged in the mounting holes 8, 9, 10 of the vehicle body panel 5 in this order. At this time, when the wire harness 4 is not twisted, the clips 1, 2, 3 are all directed toward the mounting holes 8, 9, 10 and can be easily inserted and engaged.

However, when the wire harness 4 is inserted into the one hole 6 and then the wire harness 4 is inserted into the other hole 7, the wire harness 4 is twisted, but the wire harness 4 is inserted without recognizing this state. If you do,
As shown in FIG. 8, the orientation directions of the clips 1, 2, and 3 are changed, and the clips are displaced from the mounting holes 8, 9, and 10. When the clip 1 is inserted and engaged in the mounting hole 8 in such a state, the wire harness 4 must be twisted and inserted in order to force the direction of the clip 1 toward the mounting hole 8 side. Similarly, in order to orient the clips 2 and 3 toward the mounting holes 9 and 10, the wire harness 4 must be forcibly twisted and inserted. As a result, the slack 11 is finally generated in the wire harness as shown in FIG.

Therefore, it is not possible to easily recognize whether or not the wire harness 4 is twisted. Therefore, if the wire harness 4 is accidentally attached to the vehicle body in a twisted state, the wire to the vehicle body panel 5 is There is a problem that the assembly of the harness is poor.

In view of the above, according to the present invention, the twisting can be easily recognized, the tape winding operation can be easily performed, and the assembling property to the vehicle body can be improved, and the manufacturing method of the wire harness, and The purpose is to provide manufacturing jigs.
