DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness assembling apparatus, and more particularly, to a case where a large number of branch lines are branched from the same position of a trunk line and a large number of wiring jigs for holding these branch lines need to be provided. The number of wiring jigs is reduced to improve the workability of wiring work.

[0002]

2. Description of the Related Art As shown in FIG.
The assembly is performed on an assembling apparatus 10 having a number of wiring jigs 2 to 7 erected on an assembling work table 1 in accordance with an instruction diagram shown in FIG. The wiring jig 2 holds and guides the trunk F of the wire harness, and the wiring jig 2 is provided upright at a branch position of the wire harness. Holding and guiding with the wiring jig 2,
The branch lines A to E are connected to the ends of the connectors a and b connected to the terminals of the branch lines A to E on the wire insertion side by the U-shaped wire holding portions 3 a to 7 a of the wiring jigs 3 to 7. Of the branch lines A to E are positioned.

The branch length from the trunk line of the plurality of branch lines A to E to the connector terminal is 150 mm, 150 mm, 20 mm, respectively.
The jigs 3 to 7 are erected from the erected position of the jig 2 by a distance corresponding to the branch length.

[0004]

In the above-described conventional wire harness assembling apparatus, a wiring jig for positioning and holding a terminal connector is provided for each of a plurality of branch lines branching from a trunk line. When the number of jigs increases, the number of jigs also increases accordingly, and the jigs are densely arranged on an assembly work table, which causes a problem that the assembling work becomes difficult.
In addition, there is a problem that the cost of the assembling apparatus increases as the number of wiring jigs increases.

The present invention has been made to solve the above problems, and has as its object to improve the workability by reducing the number of wiring jigs.

[0006]

According to the present invention, there is provided a wire harness assembling apparatus comprising an assembling worktable and a wiring jig erected on the assembling worktable. The jig includes a shaft erected on the assembly worktable, and a U-shaped wire holding portion protruding upward from the tip of the shaft, and the height of both side frames of the wire holding portion is adjusted up and down. Higher than the total height of the required number of connectors
A wire harness assembling apparatus is provided, wherein a connector of a branch line terminal having the same branch length that branches off from the same position of a main line of the wire harness can be held by the one wiring jig.

In the wire harness assembling apparatus according to the present invention, unlike the related art, a wiring jig for positioning and holding a terminal connector is provided for each of a plurality of branch lines branching from a predetermined position. Since the terminal connector is positioned and held by one wiring jig for a plurality of branch lines, the number of wiring jigs on the assembly work table can be reduced. Therefore, the density of the wiring jigs on the assembled drawing board is reduced, so that the wiring work can be easily performed, and the cost of the assembling apparatus can be reduced.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, wiring jigs 11 to 14 are erected at predetermined positions on an assembly work table 1. The wiring jig 11 holds and guides the trunk F, and corresponds to a branch position of the wire harness. On the other hand, the wiring jig 12,
13 and 14 are for positioning and holding the connector of the branch line terminal, and the wiring jigs 12 and 14 are for holding the side frames of the U-shaped electric wire holding portions 12a and 14a projecting from the upper ends of the shaft portions 12b and 14b. Is protruded higher than a U-shaped wire holding portion for locking and holding one terminal connector, so that the two terminal connectors can be stacked and hooked. Wiring jig 13
Is equivalent to a conventional wiring jig, and hooks and holds one ordinary terminal connector.

The wire harness to be assembled is the same as the wire harness shown in FIG. 3 and FIG. 4. A plurality of branch lines A to E branch off from the tip of the trunk line F. The design dimensions of the branch line A are 150 mm and the branch line B is Is 150mm, branch line C
Is 200 mm, branch line D is 100 mm, branch line E is 100 m
m.

The wiring jig 12 is for positioning and holding the terminal connectors a and b of the branch lines A and B having a size of 150 mm. The wiring jig 13 positions and holds the terminal connector c of the branch line C having a size of 200 mm. Wiring jig 1
4 is a terminal connector d of branch lines D and E having dimensions of 100 mm,
e is positioned and held. The wiring jig 12 is erected at a distance of 150 mm from the wiring jig 11, and
Numeral 3 stands up at a distance of 200 mm from the wiring jig 11, and a wiring jig 14 stands at a position at a distance of 100 mm from the wiring jig 11.

When assembling the wire harness, first, the branch line A branched from the trunk line F held and guided by the wiring jig 11 is used.
The terminal end of the terminal connector a on the wire insertion side is brought into contact with the U-shaped electric wire holding portion 12a of the wiring jig 12, latched and held, and then the terminal connector b of the branch line B is mounted on the upper surface of the connector a. And place the end face of the connector b on the wire insertion side into the wiring jig 12.
In contact with the U-shaped electric wire holding portion 12a.

Next, the end face on the wire insertion side of the terminal connector d of the branch line D branched from the trunk line F is brought into contact with the U-shaped wire holding portion 14a of the wiring jig 14 and latched and held. ,
The connector e of the branch line E is placed on the upper surface of the connector d, and the end face on the wire insertion side of the connector e is brought into contact with the U-shaped wire holding portion 14a of the wiring jig 14 to be latched and held.

On the other hand, the end face on the wire insertion side of the terminal connector c of the branch line C branched from the trunk line F is brought into contact with the U-shaped wire holding portion 13a of the wiring jig 13 and latched and held. Thereafter, the branch portion at the tip of the trunk line F is fixed by winding the adhesive tape T thereon.

As described above, in the present embodiment, the ends of the branch lines A and B having the same design dimensions among the branch lines branched from the tip of the trunk line F are positioned and held by one wiring jig 12,
Since the ends of the branch lines D and E having the same design dimensions are positioned and held by one wiring jig 14, the assembly worktable 1
The number of upper wiring jigs can be reduced. Therefore,
The density of the wiring jigs on the assembling work table is reduced, the work efficiency of the wiring work is improved, and the cost of the assembling apparatus can be reduced.

The present invention is not limited to this embodiment, and it goes without saying that three or more connectors may be held by one wiring jig. In the above embodiment, the terminal connectors of a plurality of branch lines having the same length branched from the same position of the main line are hooked and held by one wiring jig. The terminal can be hooked and held by one wiring jig. In this case, draw a circle centered on the branch position and the radius of the branch line at the branch position at each branch position on the assembly workbench, and hang multiple terminal connectors on the intersection of the circles centered on different branch positions. What is necessary is just to erect the wiring jig which can be stopped and held.

[0016]

As is apparent from the above description, according to the wire harness assembling apparatus of the present invention, a wiring jig for hooking and holding the connectors of a plurality of branch terminals is erected, Is used to position and hold the terminals of a plurality of branch lines branched from the main line, so that the number of wiring jigs on the work table can be reduced, and the density of wiring jigs on the assembly drawing board is small. The work efficiency of the wiring work is improved. Further, the cost of the assembling apparatus can be reduced.
