Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a wiring jig that is fixed on a wiring plate for manufacturing a wire harness and is used for manufacturing a wire harness.

(Prior Art) FIG. 6 is a schematic perspective view showing a jig for manufacturing a wire harness (JP-A-2-65008).

In this manufacturing jig, the wiring jig 3 is fixed at a predetermined position on the wiring board 1. The wiring jig 3 includes a base portion 5 and a fork portion 7. As shown in FIG. 7, the base portion 5 is provided with a notch 9 for fixing, and a bolt 11 is passed through the notch 9 to be fixed to the wiring board 1. The fork portion 7 is
It has a plurality of electric wire hooks 8 protruding from the tip side of the base portion 5. Then, the plurality of electric wires 13 can be hooked on the electric wire hooking portion 8 of the fork portion 7 for wiring, and the tape 15 can be wound to form the wire harness in a predetermined shape.

[Problems to be solved by the device]

However, as shown in FIG. 7, when the number of electric wires 13 increases, the electric wire 13A may protrude from the tip of the fork portion 7. Each of the electric wires 13 is pulled with a predetermined tension, and the length accuracy of the completed wire 13 is required. Due to this tension, the protruding electric wire 13A is stretched between the wiring jigs 3 as shown in FIG. 8, and when the tape 15 is wound in this state, when the electric wire 13A is noticed to protrude. In the end, the length of the electric wire 13A is insufficient, which eventually causes the work to be redone.

Then, this invention aims at provision of the wiring jig which can suppress that an electric wire protrudes.

[Constitution of device]

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a base portion fixed on a wiring plate for manufacturing a wire harness and a plurality of base portions protruding toward the tip side of the base portion. In a wiring jig having an electric wire hooking portion and a fork portion, the electric wire hooking portion has a cantilever and elastic stopper for preventing the electric wire from coming off.

(Operation) According to the above configuration, when the electric wire is hooked, the elastic wire retaining stopper is bent to easily hook the electric wire on the wire hooking portion of the fork portion. Once locked, the wire is restricted by the wire stopper to prevent it from protruding from between the wire hooks.

(Embodiment) An embodiment of the present invention will be described below.

1 to 3 show a wiring jig according to a first embodiment, and FIG. 1 is a perspective view showing a state before winding a tape, and is a view corresponding to FIG. 7 of the related art. Is. FIG. 2 is a perspective view with the electric wire removed, and FIG. 3 is an enlarged view for explaining the operation of FIG.

The wiring jig 3 of this embodiment also comprises a base portion 5 and a fork portion 7, and is fixed to the wiring board 1 by bolts 11 at the cutout portion 9.

The two electric wire hooking portions 8 of the fork portion 7 have a circular cross section and are covered with rubber caps 19 on the tip side. The cap 19 is provided with a tongue-shaped stopper 21 for preventing the electric wire from coming off, and is provided at a right angle to the electric wire hooking portion 17, that is, in a horizontal state so as to face each other. In other words, a cantilever elastic stopper 21 for preventing the electric wire from coming off is provided between the tip ends of the electric wire hooks 8. The tips of the two electric wire stoppers 21 are in contact with each other, and the electric wire 13 that has been once hooked is held by the wire hooking portion 7.
In order to get out of the wire, the stopper 21 for preventing the electric wire from coming off must be bent.

When the electric wire 13 is hooked on the wiring jig 3 (Fig. 2), the electric wire 13 is used to bend the electric wire slip-out prevention stopper 21 downward as shown in Fig. 3, and the electric wire 13 is directly inserted from the opened gap. And hang it down on the wire hook 8. When the wires 13 are hooked one after another in this manner, a large number of wires 13
Will be located between the electric wire hooks 8 of the fork portion 7, but even if some of the electric wires try to stick out from between the electric wire hooks 8 (see FIG. 7 of the related art), the wire is prevented from coming off. It is possible to prevent the protrusion from being restricted by the stopper 21 for use (first
Figure).

Then, the tape 15 is wound to form a wire harness. At the time of winding the tape, a large number of electric wires 13 may be lifted from between the electric wire hooks 8 against the elasticity of the electric wire stoppers 21. It should be noted that if the cap 19 is rotated and the stopper 21 for preventing the wire from coming off is positioned along the wire 13, the space between the wire hooks 8 is opened and the wire 13 can be easily lifted. Further, the cap 19 can be removed to wind the tape.

The wire harness of this embodiment manufactured in this way is used for complicated wiring of chassis electrical of an automobile.

In the above embodiment, the rubber cap 19 having the stopper 21 for preventing the electric wire from coming off is provided for each of the two electric wire hooking portions 8 constituting the fork portion 7. As shown in the figure, it is also possible to provide a rubber cap 19 having a stopper 21 for preventing the wire from coming off only on one wire hook portion 8. At this time, it is desirable that the protrusion amount of the stopper 21 for preventing the electric wire from coming off be long enough to straddle between the two electric wire hooks 8. And in this example,
In addition to the effects of the above embodiment, the effect of reducing the number of parts can be obtained.

Further, in the embodiment of FIG. 1 described above, the tips of the two wire stoppers 21 are in contact with each other, but in another embodiment, as shown in FIG. It is also possible for the tips of the to overlap. As a result, the electric wire hooking portions 8 can be easily closed, and the electric wire hooking portions 8 can be surely closed even if the length accuracy of the electric wire slip-out stopper 21 is rough. Further, by overlapping the stoppers 21 for preventing the electric wire from coming off, the electric wire 13 once hooked can be better prevented from protruding.

Further, in the embodiment shown in FIG. 1, the two wire stoppers 21 provided on the wire hooking portion 8 are separate members, but in the embodiment shown in FIG. Therefore, the cap 19 can be handled integrally, and the mounting work becomes easy.

In addition, the rubber cap 19 and the stopper 21 for preventing the electric wire from coming off.
It is also possible to mold with plastic or metal instead of rubber. Moreover, the stopper 21 for preventing the electric wire from coming off can be integrally molded with the electric wire hook portion 8.

Further, in all of the above embodiments, the wire retaining stopper 21 closes the space between the tips of the wire hook portions 8. However, in the embodiment of FIG. 4, the wire retaining stopper 21 should be formed short. Is also possible.

[Effect of the Invention] As is clear from the above, according to the configuration of the present invention,
Even if the electric wire that has been hooked once is projected, it will be difficult to protrude because it is restricted by the stopper for preventing the electric wire from coming off. Further, when the electric wire is hooked or removed, the electric wire slip-out stopper does not interfere because it can bend. Therefore, it is possible to eliminate work mistakes and rework due to the electric wire protruding, and it is possible to improve workability and quality.
