Description

  The present invention relates to a branch wire holder and a method of manufacturing a wire harness having a branch portion. Specifically, the binding band can be fastened and fixed to the branch portion of the wire harness by a simple operation.

2. Description of the Related Art Conventionally, there are many locations where branch lines branch from a trunk line in a wire harness routed in an automobile, and a wire group is wound with a tape so that the branch position does not shift. The bundling of the branch portions is performed in a state in which the electric wire bundle is arranged on the electric wire holder erected on the wire harness assembly work table. The adhesive tape for bundling these wire bundles is the position where the branch line branches from the main line, and when the wire bundle is held between the support rods of the wire holder, the support rod becomes an obstacle and the adhesive tape is turned into the wire bundle. I can't wind it.
For this reason, the adhesive tape is crossed over and wound around in a state where the electric wire holder is lowered and the electric wire bundle is removed from the electric wire holder. As described above, the operation of sticking the adhesive tape at the branching portion requires skill, and the binding state is likely to vary depending on the skill level of the operator, and the wire harness has many branching positions, and thus requires a long working time. There is a problem. In addition, since the wire bundle is taken out from the wire holder when the adhesive tape is wound around the branch portion, there is a problem that the branch position where the adhesive tape is wound is likely to be displaced, and the position accuracy of the branch portion is lowered.

In view of this, the present applicant provides a branch unit binding method in which Japanese Patent Application Laid-Open No. 2005-27463 (Patent Document 1) provides a method of binding and fixing a branch unit with a general-purpose binding band instead of tape winding. In this bundling method, as shown in FIGS. 11 (A) and 11 (B), first, an electric wire is wired through an electric wire holder 2 erected on the assembly work table 1 of the wire harness, The branch line Wb is branched in a T-shape from the main line Wa through the wire holding rods 2a, 2b, 2c provided. Next, the pair of binding bands 3A and 3B are wound around the trunk line Wa on both sides of the branch line Wb in a state where the wire bundle W of the branch portion P is not taken out from the wire holder 2 with respect to the wire bundle W. Thereafter, the leading ends of the binding bands 3A and 3B are crossed, inserted into the locking portions 3a and 3b provided at the bases of the other binding bands 3A and 3B, and locked to the branch point P of the wire bundle W. The binding bands 3A and 3B are crossed in a hooked state at the corresponding positions and fastened. The binding bands 3A and 3B are inserted into a separate auxiliary member 4 for holding the base portions of the binding bands at a constant interval, thereby improving workability.
When the clip 5 is fixed at the branch point P, as shown in FIG. 11C, a separate auxiliary member 6 having the clip 5 is inserted and held in both the binding bands 3A and 3B. Thus, the clip 5 can be fixed near the branch point P.

As described above, according to the method shown in FIGS. 11 (A) and 11 (B), the general-purpose binding is performed while maintaining the holding state of the branch point P of the wire bundle W held by the wire holder 2. Bands 3A and 3B can be used to bind in a crossed state. However, in order to wind the binding bands 3A, 3B around the branch point P, it is necessary to perform the winding work inside the wire holding bars 2a, 2b, 2c while being careful not to wind the wire holding bars 2a, 2b, 2c. In addition, the two binding bands 3A and 3B must be crossed so as to be inserted into the locking portions on the other side, which complicates the work procedure.
Further, according to the method shown in FIG. 11C, the clip 5 can be attached in the vicinity of the branch point P. In this case, a separate auxiliary component 6 is separately required and the center position of the branch point P is required. If the clip 5 can be attached to the vehicle body, when the wire harness is attached to the vehicle body, the wire harness can be stably fixed at a small number of points. However, in the above method, there is no means for positioning the attachment position of the clip 5, There is a problem that it is difficult to attach the clip 5 to a position that exactly matches the point P.
