DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring jig used for manufacturing a wire harness, and more particularly to a wiring jig used at a location where a branch line branches off from a main line.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 4, a plurality of wiring jigs 3 are fixed on a wiring board 1 and wires (main wires 15, This is performed while bridging the branch line 19) (JP-A-2-65008).

In this case, the wiring jig 3 includes a base 5 and a fork 7 as shown in FIG. Base part 5
The fixing jig 3 is fixed on the wiring board 1 by fastening a bolt 11 to the wiring board 1 by passing the bolt 11 through the notch 9.

[0004] The fork 7 has a plurality of, for example, two wire hooks 13 protruding from the upper end of the base portion 5. Hold. In addition, at a location where the branch line 19 branches off from the main line 15, the one wire hooking portion 13 is used as a support point and is used for branching the branch line 19.

Conventionally, when the branch line 19 is branched from the main line 15, as shown in part A of FIG. 4, the branch line 19 is drawn in the branching direction with the same fork 7 holding the main line 15 as a supporting point. Was.

[0006]

For this reason, the branch position, the thickness of the branch line, and the like are regulated by the fork portion 7 that holds the trunk 15.

For example, regarding the position, not only the position in the wiring direction (extending direction) of the trunk line but also the position in the cross-sectional direction of the trunk line, that is, the position where the branch line is drawn out in the cross section of the main line, is regulated by the fork portion. Therefore,
In the case where a small number of branch lines are branched off from the main line, FIG.
As shown in part B, the branch line 19 may be pulled out while being suspended from the side edge of the trunk line 15, and the length of the branch line 19 may not be manufactured as designed. In this case, since the branch wire 19 is further pulled out in a suspended state, another problem has arisen that the operation of winding the tape T and binding the electric wires becomes difficult.

In addition, for example, when a thick branch line is branched, there has been a problem that the fork portion disturbs the tape binding operation. That is, the wiring work is usually performed while tightening the electric wires. Then, at the time of tape winding and binding, the electric wire at the work location is temporarily removed from the fork portion, and the tape is wound, and thereafter, the wire is returned to the fork portion again.
The work is proceeding while repeating these steps. But,
When returning the branch where the tape is wound to the original fork,
Since the diameter is increased by the amount of tape winding, FIG.
As shown in (1), the branch line 19 and the fork portion 7 may interfere with each other, making it difficult to hook the branch portion on the fork portion 7.

As shown in FIG. 8, there is a conventional example in which two kinds of forks, a main line holding fork 7a and a branching fork 7b, are provided so as to be shifted inward and outward. Could not be solved.

According to the present invention, in consideration of the above circumstances, the position where the branch line is branched from the main line and the thickness of the branch line can be freely set without being restricted by the main line holding fork. It is an object of the present invention to provide a wiring jig that is not restricted by a fork portion that causes difficulty in tape winding work.

[0011]

According to a first aspect of the present invention, there is provided a wiring jig comprising: a base fixed on a wiring board for manufacturing a wire harness; A fork portion having a plurality of wire hooks protruding at an upper end, and a wiring jig in which an electric wire is passed between the wire hooks of the fork portion. A main line holding fork and a branch fork for branching a branch line from a main line are provided separately, and the main line holding fork and the branching fork are displaced in the main line wiring direction. And

The wiring jig according to a second aspect of the present invention is characterized in that the branching fork is provided so as to be retractable in a direction to avoid interference with an electric wire.

[0013]

According to the wiring jig having the above construction, the trunk can be hung on the trunk holding fork, and the branch can be branched using the branch fork as a support point. Therefore, the branch position can be determined without being restricted to the main line holding position. Also, the thickness of the branch line can be set regardless of the trunk line holding fork. Also, since the trunk holding fork is displaced from the branch fork, there is no possibility that the branch portion will interfere with the trunk holding fork when the tape is bound.

When the branching portion interferes with the branching fork, the branching fork may be retracted.

[0015]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a wiring jig according to an embodiment of the present invention, and FIG. 2 is a plan view showing a state where an electric wire is held.

The wiring jig of this embodiment is provided with a main line holding fork 26 and a branching fork 27 separately on a rectangular parallelepiped box-like base portion 25. The base portion 25 is fixed on a wiring board (see FIG. 4) with bolts, similarly to the conventional example.

The main line holding fork 26 includes a base 25
And a pair of wire hooks (spokes) 26a, 26a spaced apart from each other in a direction in which the trunk line 15 passes (the direction of the trunk line). Wire hook 2
The diameters and intervals of 6a and 26a are set to dimensions that are considered appropriate for holding the trunk line.

The branching fork 27 is provided upright at the center of the base portion 25, and as a result, the trunk holding fork 2
6 and the fork 27 for branching are shifted from each other in the direction in which the trunk line 15 passes.

The branching fork 27 is provided with a pair of spaced wire hooks (spokes) 27a, 27a, similarly to the trunk line holding fork 26, and is formed in a U-shape with its lower ends connected. I have. When in use, it protrudes from the upper end of the base 25 similarly to the main line holding fork 26, and is disposed so as to be retractable in a housing hole 25 a formed inside the base 25 when unnecessary. The accommodation hole 25 a is formed as a vertically elongated slit-like space extending downward from the upper surface of the base portion 25.

The wire hooking portion 27 of the branching fork 27
a, 27a are electric wire hooking portions 26 of the main line holding fork 26;
a, 26a. This diameter is set to a size that is considered appropriate for branching the branch line 19. Also, the wire hooking portions 27a, 27a of the branching fork 27
The interval is set smaller than the wire hooking portions 26a of the main line holding fork 26, and the branching fork 27 is located inside the main line holding fork 26 (FIG. 2).
reference).

At the lower part of the U-shaped branching fork 27, a support rod 28 is integrated, and at the lower end of the support rod 28, a horizontal lever 29 is inserted. The lever 29 is moved from the side of the base 25 to the base 25.
Can move up and down in a moving hole 25b formed toward the inside of the device, and can slide in its own axial direction. And one end protrudes out of the base part 25,
A slide operation and a vertical movement operation can be performed from outside.

The moving hole 25b of the lever 29 communicates with the housing hole 25a of the fork 27 for branching.
It has a fixing hole 25c for receiving the tip of the lever 29. Then, by inserting the tip of the lever 29 into the fixing hole 25c, the lever 29 is fixed at the upper end position, and by releasing the inserted state, the lever 29 is allowed to move up and down.

Next, the operation will be described with reference to FIGS.

In the wiring operation, the trunk 15 is passed between the electric wire hooks 26a of the trunk holding fork 26. At this time, the branch line 19 branching out of the trunk line 15 is passed between the two wire hooking portions 27a of the branching fork 27.
Then, the branch wire 19 is connected to the wire hook 2 of the fork 27 for branching.
Pull out in the branching direction with 7a as the support point.

In this state, tape bundling is started, and when the work reaches the branch point, the electric wire at the branch point is temporarily removed from the forks 26 and 27. Then, after the tape is wound, the wire hooking portion 26 of the main line holding fork 26 is again used.
a, return to between 26a. At this time, since the branch position is displaced from the main line holding fork 26, it does not hinder the main line holding fork 26 from returning the electric wire.

If the branching fork 27 is in the way,
By lowering with the lever 29 once pulled,
As shown in FIG. 3, the branching fork 27 is retracted into the accommodation hole 25a. Accordingly, even when the diameter of the branched branch wire 19 is increased by the tape winding, the fork portion does not interfere, and the trunk 15 is securely held by the trunk holding fork 26. Become. Therefore, wiring work becomes easy.

Further, since the support point for the branch is taken by the fork portion 27 provided separately from the one for holding the main line, the setting relating to the branch, such as the degree of freedom of the branch position and the thickness of the branch line, can be performed. It can be performed freely without being restricted by the fork 26. In particular, in this embodiment, since the wire hooks 27a, 27a of the branch fork 27 are arranged inside the wire hooks 26a, 26a of the trunk holding fork 26, the position where the branch wire 19 is pulled out is determined by the trunk line. 15 can be set near the center, and the accuracy of the length of the branch line 19 can be improved. Further, the branch lines are not hung as in the conventional example shown in FIG. 6, so that the tape winding operation becomes easy.

In the above embodiment, the branching fork 27 is configured to move only in the vertical direction and retract, but the retracting direction can be changed as appropriate. Also,
The branching fork 27 may be configured to be adjustable in the axial direction of the trunk line, or may be configured to be able to adjust the interval between the wire hooks 27a.

Further, in the above embodiment, the case where the number of the wire hooking portions is two for each fork portion is shown, but the number can be changed as appropriate.

[0031]

As described above, according to the wiring jig of the present invention, the trunk holding fork and the branching fork are separately provided, and both forks are displaced in the wiring direction of the trunk. Therefore, the branch position and the thickness of the branch line can be freely set without being restricted by the trunk line holding fork. Therefore, the branch line can be accurately drawn out without being restricted to the main line holding position. For this reason,
The dimensional accuracy of the branch lines can be improved, and the tape winding operation becomes easier.

Further, since the branching fork is displaced from the main line holding fork in the axial direction of the main line, there is no need to worry about the branch portion interfering with the main line holding fork at the time of tape binding, and the tape winding operation becomes easy.

Further, when the branching portion interferes with the branching fork, the branching fork may be retracted, so that there is no obstacle at the time of tape winding and the wiring work can be facilitated.
