DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electric wire, an air pipe,
The present invention relates to a wire holder for bundling a wire such as an optical fiber, installing a clip portion at a center of a branch formed at a predetermined position, and fixing the branch to a predetermined mounting position.

[0002]

2. Description of the Related Art In recent years, wire rods for binding wires such as electric wires, optical fibers, and air pipes for vehicles and communications, and holding and fixing a predetermined wiring direction at a predetermined mounting position. Tools (fixing clips) are widely used. Particularly, in a wire harness routed in a vehicle, a trunk portion where a large amount of wires are bundled, a branch line portion composed of several wires routed to electric and electronic components, or a branch portion where these wires branch. A fixing clip is often used for holding and binding the periphery. Conventionally widely used fixing clips include a band-type clip (hereinafter referred to as a band clip) 30 as shown in FIG. 3A or a plate-type clip as shown in FIG. (Hereinafter, referred to as a plate clip) 40.

[0003] A method of attaching these fixing clips to the vicinity of a branch portion of a wire will be described with reference to FIG. In the vehicle wire harness, the mounting position of the fixing clip, particularly the installation size of the clip portion 2, is determined extremely strictly in relation to the mounting hole size on the vehicle panel side. If the distance between the clip parts 2 is longer than the mounting hole pitch, the wire harness between the fixing clips will be slackened, and it will be a source of abnormal noise when the vehicle is running. There is a problem that the properties are significantly deteriorated. Therefore, the wire harness assembly drawing board is provided with a branching jig 20 for forming a branch portion at a predetermined position and a clip mounting jig 60 for mounting a fixing clip at a predetermined dimensional position. I have. As shown in FIG. 4 (a), the branching jig 20 has, for example, a trifurcated branching head 21 according to the branching shape of the wire harness.
And a rod part 22 that can move up and down to support the branch head part 21 at the work height for assembling the wire harness. Further, as shown in FIG. 4B, the clip attaching jig 60 has a head portion 11 provided with a locking groove to which a fixing clip is temporarily fixed, and a predetermined attaching portion which brings the head portion 11 close to the wire harness 50. A rotation mechanism 61 for rotating between a position and a standby position (depicted by a two-dot chain line in the figure), and a rod 6 for supporting the head 11 and the rotation mechanism 61
And 2.

[0004]

SUMMARY OF THE INVENTION Wire harness 50
To attach the fixing clip to the branch portion 51, first, the electric wire laid in a predetermined branch shape by the branch jig 20 is wound around a tape. Next, when the wire harness 50 is on the branch jig 20, the fixing clip or the clip mounting jig 60 interferes with the branch head 21, and the fixing clip cannot be mounted. After the rod portion 22 of 20 is lowered to avoid the branch head portion 21 from the working height, the clip mounting jig 6 to which the band clip 30 or the plate clip 40 is temporarily fixed is attached.
The head unit 11 is rotated from the standby position to the mounting position as shown by the arrow B, and the position on the higher harness where the fixing clip is mounted is determined. In such a fixing clip mounting method, when the fixing clip is mounted, the branching portion 51 is not supported and fixed by the branching jig 20, so the mounting position of the fixing clip is determined to a predetermined dimensional position. And had a problem in dimensional accuracy.

On the other hand, in the wire harness in which the fixing clip is attached at a predetermined position in this manner, the presence or absence of the clip is detected in a later step to confirm that the clip has been forgotten to be attached or that the attachment position is incorrect. In the step of detecting the presence or absence of the clip, as shown in FIG. 5, the position of the branch portion 51 is determined by the above-described branch jig 20, and the clip is attached at a position separated by a predetermined dimension L from the center of the branch portion 51. The presence or absence of the band clip 30 or the plate clip 40 attached to the center (or the vicinity thereof) of the branch portion 51 is checked by the clip detection jig 70. The clip detection jig 70 includes a detection head 71 for confirming the presence or absence of a fixing clip, and the detection head 71 is connected to the wire harness 5.
It is composed of a rod portion 72 that is supported at a clip mounting height above zero.

In such a clip presence / absence detection step, when the band clip 30 is targeted as shown in FIG. 5A, it cannot be attached to the center of the branch portion 51 of the wire harness 50 due to its structure. A bundling method in which a straight line portion inevitably separated from the branch portion 51 is tightened by the band portion 6, and the installation position of the clip portion 2 is separated from the center of the branch portion 51 by a predetermined distance L, and a clip detection judge for detecting the presence or absence thereof The tool 70 is provided at a predetermined distance from the branching jig 20. Therefore, the clip detection jig 70 for detecting the band clip 30 only needs to be installed at least a distance L from the branch jig 20, and there is no hindrance to the clip detection. However, in the plate clip 40, as shown in FIG.
The tape fixing portions 32 provided at both ends of the plate 31 are connected to the electric wire portions which are on the same straight line via the branch portion 51.
Is fixed with a fixing tape 33 so as to be fixed.
Although the clip portion 2 can be installed at the center of the clip jig 20, the positional accuracy between the center of the branch portion 51 and the clip portion 2 is low as described above. As a result, the detection head 71 of the jig 70 interferes or competes with the detection head 71, and a satisfactory detection operation cannot be performed. For this reason, the clip portion 2 cannot be accurately set at the center of the branch portion 51 of the conventional wire harness 50. In particular, the branch portion 51 has a diameter larger than that of the straight portion because the densely packed electric wires are wound from each wiring direction. Thus, there is a problem that it becomes a source of interference with peripheral members and abnormal noise when the vehicle is running.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and a clip portion can be set at the center of a branch portion of a wire harness, so that the wire harness can be properly fixed to a predetermined mounting hole. An object of the present invention is to provide a wire holder capable of performing a satisfactory clip detecting operation at the time of inspection.
