Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a wire harness, and to reduce the number of assembling steps when assembling a wire harness in which a plurality of connectors are juxtaposed at a terminal of a trunk line.

[0002]

2. Description of the Related Art Generally, a wire harness for an automobile is provided with a branch line 2 branched from a trunk line 1 as described in Japanese Patent Application Laid-Open No. Hei 8-249935. C1 and C2 are attached (FIG. 4A). As shown in FIG. 4 (B), the wire harness having such branched branch lines 2 is assembled by laying out wires along a large number of wire holders 4 erected on an assembly work plate 3. . Then, in order to assemble the branch line 2 branched from the trunk line 1, the branch wire holders 5 are erected at the starting point P1 of the branch and the branch end P2, respectively.
The branch line 2 and the connector C2 are held along the branch wire holder 5.

When a plurality of connectors C11 and C12 attached to a wire harness 10 are connected to the same device, the form of the wire harness 10 is as shown in FIG.
The result is as shown in FIG. That is, since it is necessary to arrange and fix the connector C12 attached to the branch line 12 at a required interval in the vicinity of the connector C11 attached to the terminal of the trunk line 11, the connector C12 is fixed to the trunk line 11 by the tape T1, and The tape T is also located at the appropriate position in the middle of 12.
2 secures to the main line 11. In order to assemble such a wire harness 10, as shown in FIG. 5B, a cloth for the trunk 11 is separately provided on an assembly work plate 13 separately from an electric wire holder 14 for holding the trunk 11. A branch starting point P11 of the branch line 12 and a branch end P12 of the branch path that is opened at a required angle from the wiring path of the trunk line 11 during the line path,
It is necessary to install the wire holders 15a and 15b, respectively. When assembling the branch line 12, first, as shown by a two-dot chain line in FIG. 5B, the branch line 12 is first branched from the wire holder 15a at the branch starting point P11 and the distal end connector C12 is branched into the branch distal end P12. Is held. Next, when the processing of the post-insertion terminal for the connector C11 of the trunk line 11 is completed, as shown by the solid line, the connector C12 of the branch line 12 is detached from the wire holder 15b and placed on the trunk line 11 and the tape T1 is removed. To fix it.

[0004]

The wire harness 10 having the above-mentioned specifications is finally connected to the connector C12 of the branch line 12.
Is fixed to the trunk line 11, and as a result, the work of temporarily holding the connector C12 at the branching end P12 and the work of removing the connector C12 from the branch end P12 and arranging it on the trunk line 11 become extra, and the number of steps increases. is there. Also,
Along with this, there is also a problem that the installation of the wire holder 15b itself at the branch tip P12 and the space thereof are wasted.

The present invention has been made in view of the above problems, and has as its object to provide a method for assembling a wire harness having the above specifications without branching a branch line during assembly.

[0006]

In order to achieve the above object, the present invention provides a second connector attached to a terminal of a branch line near a first connector attached to a terminal of a trunk line of a wire harness. A method of assembling a wire harness in which first and second connectors are juxtaposed on an axis of a main line by arranging and fixing by tape winding. Wire holders are erected at a receiving position of the first connector attached to the main line and at a receiving position of a branch starting point of the wire bundle branched from the main line, and the first line is provided in the wiring route of the main line. A common holder capable of holding both the trunk line and the branch line is erected adjacent to the electric wire holder of the connector, and a trunk line provided with the first connector is arranged along the electric wire holder and the common holder. While laying, A branch line provided with the second connector is laid along the trunk line, and the second connector is arranged in the vicinity of the first connector by holding the second connector on the shared holder. Next, the present invention provides a method for assembling a wire harness, wherein the second connector is tape-fixed to the main line.

With the above structure, the branch lines need only be laid out on a path that matches the wiring path of the main line, and there is no need to branch off, and the assembling process can be simplified. Along with this, the two electric wire holders conventionally used at the branch starting point and the branch tip can be used as one common holder.

More specifically, as the wire harness that can be assembled by the above method, it is preferable that the second connector attached to the branch line is not set so that a terminal for insertion is inserted through the second connector. This is because the trunk line passes through the holding position of the second connector, so that it becomes difficult to insert the last insertion terminal. Further, it is preferable that the number of electric wires of the trunk line is set so small that the second connector is not buried by the trunk line.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a wire harness W / H to be assembled according to the present invention, and shows an example of a horn circuit connected to a horn. This wire harness W / H includes a first connector C21 (minus side of the horn) attached to a terminal of the trunk line 21,

FIGS. 3A to 3C show a process of assembling the wire harness W / H of the above specification. On the assembly work board 23, the wire holders 25a and 25b are respectively located at the receiving position of the first connector C21 of the trunk line 21 and the receiving position of the branch starting point P21 of the wire bundle 24 of the third connector C23 branched from the trunk line 21. And the wire holder 25c at the branch end for the third connector C23 is erected.
Further, in the wiring route of the trunk line 21, a shared holding member 26 of a size capable of holding both the trunk line 21 and the branch line 22 in a position adjacent to the wire holding member 25a holding the first connector C21. Has been established. The distance between the common holder 26 and the wire holder 25a is set to match the required distance between the first connector C21 and the second connector C22.

At a substantially intermediate position between the wire holders 25a and 25b, a tape T22 is wrapped around the branch line 22 and the branch line 22 is fixed to the main line 21 in order to prevent the branch line 22 from becoming uneven.

[0013]

As is apparent from the above description, according to the method of assembling a wire harness of the present invention, when assembling a wire harness in which a plurality of connectors are arranged at a terminal of a trunk line and a position near the terminal, a conventional method is used. In comparison, it is possible to reduce the number of wire holders required for assembly and the space occupied on the assembly work plate. Along with this, the operation of merging the branch line into the trunk line as in the related art is eliminated, so that the number of assembly steps can be reduced.
