Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness assembly jig used when wiring a wire harness on a wiring drawing board.

[0002]

2. Description of the Related Art As shown in FIG. 7, a wire harness assembling jig 50 of this type is an electric wire guide formed in a substantially U-shape for guiding an electric wire to an upper end of an electric wire guide rod 51 which is long in the vertical direction. A Y-shaped one provided with a portion 52 is generally used, and the lower end portion of the electric wire guide rod 51 is fixed to the wiring diagram board A for use.

Such a wire harness assembly jig 50
Is used not only for holding an intermediate electric wire portion of a wire harness to be laid but also for holding an end portion of the wire harness to which a connector is connected. Thus, when used for the end of the wire harness, as shown in FIG.
The wire harness end is positioned by passing the wire W portion through the wire guide portion 52 and bringing the connector C into contact with the wire guide portion 52.

By the way, the connector C is connected to the wire guide portion 52.
When contacting and positioning the connector C, the connector C is arranged such that the longitudinal direction of the connector C faces the vertical direction so that the contact area between the housing of the connector C and the wire guide portion 52 is increased as much as possible. However, since it becomes difficult to see the electric wires W when arranged in this way, the electric wire bundle often comes to a position just eccentric from the central portion of the connector C when the electric wires W are bundled. There is such a problem.

For this reason, as shown in FIG. 9, the wire harness assembly is attached to the wire guide rod 61 with the U-shaped wire guide portion 62 facing sideways so that the wire W can be easily seen by a worker performing a binding operation. The jig 60 is used.

[0006]

However, in the wire harness assembling jig 60 described above, the wire W is inserted into the wire guide portion 62 from the lateral direction. In comparison, there is a drawback in that the electric wire W may come off the electric wire guide portion 62 due to a slight shock or the like.

Since the wire harness assembly jigs 50 and 60 of this kind are fixedly installed on the wiring diagram board A,
Usually, in consideration of workability of connecting the electric wire W to the connector C, looseness of the electric wire W, etc., each electric wire W constituting the wire harness is slightly longer with a margin, and when these electric wires W are bundled. For the first time, the wire harness H having a substantially predetermined length is completed. Therefore, there is no particular problem when accuracy is not required for the harness length, but the wire W that is set to a substantially predetermined length is used for a wire harness that requires relatively high accuracy such as a fine wire harness. Since it is necessary to use a wire harness assembling jig 50, 60 that is fixedly installed during wiring, it is difficult to connect each wire W to the connector C and fine adjustment of position is required. There is a problem that you cannot do it.

Therefore, an object of the present invention is to provide a wire harness assembly jig in which the electric wire is not easily detached during wiring, the workability of connecting the electric wire and the connector is excellent, and delicate position adjustment is possible.

[0009]

In order to solve the above problems, the present invention provides a wire harness assembly jig which is attached to a wiring drawing board for laying a wire harness.
With respect to the wiring diagram board, a jig body movably attached in a predetermined range in the wiring direction of the wire harness,
Fixing means for fixing the jig main body to the wiring diagram board at an arbitrary position within the predetermined range, the jig main body being inserted in an electric wire forming a wire harness, and having a horizontal direction with one end opened. Of the slit, a locking portion formed on the peripheral edge of the slit for locking the connector connected to the electric wire, and formed at the open end of the slit so as to project forward with respect to the locking portion. The present invention provides a wire harness assembling jig having a pullout preventing portion.

Further, the jig body may be movably mounted in a wiring direction of the wire harness with respect to a pedestal portion having a height adjusting mechanism fixed to a wiring drawing board.

Further, it is preferable that the engaging portion is formed in a planar shape, and concretely, it is conceivable that the jig body is formed by a plate-shaped member.

Further, the retaining portion can be formed by bending a part of a plate-shaped member forming the jig main body to the front side, and the connector is fitted in the peripheral edge of the locking portion. A housing may be provided.

[0013]

In the wire harness assembling jig constructed as described above, the presence of the retaining portion prevents the slit of the connector once locked from being displaced toward the open end side. Further, when the jig body is not fixed to the drawing board at an appropriate position, the jig body can be moved to an arbitrary position in the wiring direction and fixed to the wiring drawing board at that position.

Further, in the case where the pedestal is provided, the wiring height of the wire harness is changed by the height adjusting mechanism of the pedestal.

Further, in the case where the locking portion is formed in a flat shape, the contact area of the connector with the housing is increased, and the connector is securely locked.

Further, in the case where a housing is provided at the peripheral edge of the engaging portion, the engaged connector prevents the displacement of the position of the connector and is always held at the same position.

And a washer 22, and is fixed to the wiring diagram board A via a pedestal 30.

The jig body 10 is shown in FIG.
As shown in (b) and (c), a locking plate 13 is erected at the rear end of the board 11, and the board 11 has two elongated holes 12 through which the screws 21 are inserted. It is formed in parallel so that its longitudinal direction is orthogonal to the locking plate 13.

As shown in FIGS. 2 (b) and 2 (c), the locking plate 13 is provided with a lateral slit 1 at the central portion in the vertical direction.
4 is formed, and the peripheral edge portion of the slit 14 constitutes a locking surface 15 as a locking portion of the connector C (see FIG. 4).

Further, as shown in FIG. 4A, the locking plate 13 is bent by the open end side of the slit 14 toward the front end side of the substrate 11 by about 45 degrees so that the locking surface 15 is formed. A retaining portion 16 of the connector C is formed so as to extend from the front side of the slit C. In the retaining portion 16, the width of the slit 14 is widened toward the open end side. The bending angle α of the retaining portion 16 is preferably large considering only the retaining function of the connector C, but if it is too large, it becomes difficult to remove the connector C.
Around 5 degrees is suitable.

As shown in FIGS. 1 and 5, the pedestal 30 includes a support rod 31 fixed to the wiring diagram board A and a support plate 36 horizontally fixed to the upper end of the support rod 31. The jig body 10 is formed on the support plate 36.

The jig body 10 is used by fixing the jig body 10 to the pedestal 30 by screwing the screw 21 passed through to the support plate 36. At this time, if the attachment position of the jig body 10 is not appropriate, the screw 2
1 may be loosened and the jig body 10 may be slid to perform fine adjustment, and then fixed again at that position.

Further, as described above, when assembling the wire harness, the slit 14 for inserting the electric wire is formed laterally in the locking plate 13, so that the assembling condition can be easily grasped from above. Even when the tape is wound to bundle a plurality of electric wires, the electric wires can be bundled so that the electric wire bundle is located at the center of the connector C without eccentricity.

Even if the slit 14 is formed laterally, the retaining plate 16 is temporarily provided due to the existence of the retaining portion 16.
The connector C locked to the jig does not come off from the jig body 10 due to a slight shock or the like.

FIG. 6 shows another embodiment. Since this wire harness assembly jig 2 has substantially the same configuration as the wire harness assembly jig 1 of the above-described embodiment, the same components are designated by the same reference numerals, and the description thereof will be omitted. Only different parts will be described. .

The difference between this wire harness assembly jig 2 and the wire harness assembly jig 1 is that in FIG.
As shown in (b), a housing 17 in which the connector C is fitted is provided at the peripheral edge of the locking surface 15 of the jig body 10. The housing 17 extends from the upper end and the lower end of the locking surface 15 and the side end on which the retaining portion 16 is not formed to the front end side of the substrate 11, respectively. There is an advantage that the stopped connector C is reliably positioned.
