DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electric wire, an air pipe,
Forming a branch portion at a predetermined position of a wire such as an optical fiber,
Also, the present invention relates to a branch clip which binds and holds a branch portion and engages and fixes a predetermined mounting position, and a good wire branch jig to which the branch clip is applied.

[0002]

2. Description of the Related Art In recent years, wires, such as wires for vehicles and communications, and wires such as optical fibers or air pipes have been bundled and held in a predetermined mounting position in a predetermined wiring direction and fixed. 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 off. 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. 5A or a plate-type clip as shown in FIG. 5B. (Hereinafter, referred to as a plate clip) 40.

[0006] A method of binding and holding a branch portion of a wire using these fixing clips will be described with reference to FIG. 6. In the band clip 30, as shown in FIG. Since it cannot be attached to the center of the branch portion 51, the straight line portion separated from the branch portion 51 is inevitably tightened by the band portion 22, and the installation position of the clip portion 6 is the distance L from the center of the branch portion 51. They will be separated. Further, in the plate clip 40, as shown in FIG. 6B, the plate 31
The tape stoppers 32 provided at both ends of the fixing tape 3
3, the clip part 6 can be installed at the center of the branch part 51.

There is a demand for attaching the clip portion to the center of the branch portion because the branch portion is formed by tape-wrapping wires that are densely arranged in each wiring direction. This is based on the problem of interference with members and a source of abnormal noise.

[0005]

However, there are various restrictions and problems in attaching the fixing clip shown in FIG. 6 to the branch portion of the wire harness. In the band clip 30, since the clip portion 6 cannot be set at the center of the branch portion 51, the vibration of the branch portion 51 cannot be sufficiently absorbed, and there is a problem that abnormal noise is generated. In particular, in the case of the wire harness 50 having a large diameter, the distance L from the center of the branch portion 51 to the installation position of the clip portion 6 becomes large, and the generation of abnormal noise becomes remarkable. In order to suppress such a problem, a form in which the band clip 30 is attached to all the straight portions extending from the branch portion 51 can be considered. However, workability at the time of assembling the wire harness or mounting it to the vehicle is significantly deteriorated. With clip part 6
However, there is a drawback that new problems such as a decrease in strength due to an increase in the number of mounting holes on the vehicle side with which the vehicle engages.

In the plate clip 40, the clip portion 6 can be installed at the center of the branch portion 51.
There is a problem of a decrease in dimensional accuracy. That is, in the vehicle wire harness, the mounting position of the fixing clip, particularly the installation position of the clip portion, is determined extremely strictly in relation to the mounting hole size on the vehicle panel side. If the distance between the clip parts is longer than the mounting hole pitch, the wire harness between the clips will sag, causing abnormal noise when the vehicle is running.If the distance is short, the workability when mounting to the vehicle will be significantly deteriorated. There is a problem. Therefore, the wire harness assembly drawing board is provided with a branch jig for forming a branch portion at a predetermined position and a clip jig for attaching a fixing clip at a predetermined dimension position. As shown in FIG. 7A, the branch jig 60 has a three-pronged branch head 61 corresponding to the branch shape.
And a vertically movable rod portion 62 for supporting the branch head portion 61 at the work height for assembling the wire harness. Also, as shown in FIG. 7B, the clip jig 70 has a head portion 11 provided with a locking groove to which the clip portion 6 is temporarily fixed, and a predetermined mounting position where the head portion 11 is located close to the wire harness 50. Rotating mechanism 71 for rotating between the robot and a standby position (depicted by a two-dot chain line in the figure), and a rod 7 for supporting the head 11 and the rotating mechanism 71
And 2. Attachment of the fixing clip to the branch portion 51 is performed by firstly winding an electric wire laid in a predetermined branch shape by a branch jig 60 into a tape. When the wire harness 50 is on the branch jig 60, the fixing clip or the clip jig 70 interferes with the branch head 61, and the fixing clip cannot be attached.
The rod portion 62 of the branching jig 60 is lowered to move the branching head portion 61 away from the working height.
The head 11 of the clip jig 70 to which the plate clip 40 is temporarily fixed is rotated from the standby position to the mounting position as shown by the arrow C, and the position on the wire harness where the fixing clip is mounted is determined. The method of attaching such a fixing clip is as follows.
Alternatively, the present invention is applied to any fixing clip of the plate clip 40. However, when the fixing clip is mounted, the branching portion 51 is not supported and fixed by the branching jig 60. Had a problem.
