2. Description of the Related Art A wire harness including a plurality of electric wires and a connector for accommodating a terminal connected to each end of the electric wire checks whether or not each of the terminals is electrically connected to another terminal. By doing so, pass / fail has been determined.

Conventionally, this type of wire harness inspection method has been performed according to the following procedure. One of the terminals of the wire harness is selected and applied to the selected terminal to determine whether the potential of the other terminal is high or low.
The potential is applied to all the terminals in order, and the potentials of all the terminals except the applied terminal in each case are sequentially determined. Then, the mutual conduction state of all the terminals is grasped.

[0004] By comparing the state of conduction between terminals grasped as described above and the state of conduction between terminals when the wire harness is normal, it is possible to determine whether the wire harness is good or abnormal and whether there is an abnormality. Has grasped the abnormal spot.

As described above, in order to inspect a wire harness, for example, an inspection jig 41 shown in FIG. 7 has been used. The inspection jig 41 illustrated in FIG. 7 holds the connector and ensures conduction with each terminal of the connector.

And the continuity inspection unit 44 are connected to each other. When the operation lever 43 is rotated, the continuity inspection unit 44 is slid by the link mechanism so as to come into contact with and separate from the connector receiving unit 45.

The inspection jig 41 places the connector on the connector receiving portion 45 and operates the operation lever 43 to bring the continuity inspection portion 44 close to the connector mounted on the connector receiving portion 45. The continuity between each terminal of the connector and the contact is ensured. Then, the voltage is sequentially applied to the terminals via the contacts to grasp the state of conduction between the terminals.

[0011]

However, in the above-described inspection jig 41, the continuity inspection section 44 is slidably supported by the side wall 46 and the like so as to come into contact with and separate from the connector receiving section 45.

The wiring board includes a tie that can tie a plurality of electric wires. The wire harness manufacturing apparatus, while tying an electric wire to the knot of the wiring board, laying the electric wire in a predetermined pattern,
The worker has assembled the wire harness by assembling a protector or the like at a predetermined location while the wiring board is running.

However, since the above-described inspection jig 41 is large, a continuity inspection device has been installed at a position distant from the running path of the wiring board in order to inspect the continuity of the wire harness. The continuity inspection device includes a plurality of the inspection jigs 41, and after attaching a connector of the wire harness to each inspection jig, a voltage is applied to each terminal of the wire harness. Then, the continuity inspection device grasps the continuity of all terminals of the wire harness, and compares the grasped continuity with the continuity of terminals when the wire harness is normal. In addition, the quality of the wire harness and, if there is an abnormality, the abnormal part has been grasped.

As described above, the conventional inspection jig 41 described above is used.
When using the above, it was necessary to transport the wire harness assembled by the wire harness manufacturing device including the wiring board to the above-described inspection device. For this reason, the time required for the production of the wire harness is lengthened, which has been a factor of reducing the production efficiency of the wire harness. further,
A space for installing an inspection device is also required, and the area required for installation on a wire harness production line tends to increase.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wire harness inspection jig capable of reducing the size, suppressing the number of parts and suppressing the deterioration of maintainability and the rise in cost. An object of the present invention is to provide a wiring board that can suppress a decrease in production efficiency and a wire harness manufacturing apparatus that can suppress a decrease in production efficiency of a wire harness.

Since the operating portion 33 projects outward from the outer surface 22b, the end surface 8 of the connector 8 of the locking portion 32
The operability at the time of releasing the engagement with the a is improved. Slope 3
Since the connector 4 is inclined as described above, when the connector 8 is brought closer to the opening 24, the operation lever 12 is displaced so that the locking portion 32 does not prevent the connector 8 from entering the connector housing chamber 23. Therefore, the connector 8 can be held only by bringing the connector 8 closer to the opening 24, and the operability when holding the connector 8 is also improved.

Furthermore, the size of the wire harness inspection jig 1 can be reduced, and the jig body 10 and the cover 14 can be used.
Since it is made of a synthetic resin, the weight of the wire harness inspection jig 1 can be reduced. For this reason, it becomes possible to attach the wire harness inspection jig 1 to the board body 16a of the wiring board 16 erected substantially in the vertical direction. An inspection can be performed.

Therefore, the assembled wire harness 2
Can be reduced from the wire harness manufacturing device 17 to the dedicated continuity inspection device. Therefore, a decrease in the production efficiency of the wire harness 2 can be suppressed.
Further, since it is not necessary to install a dedicated continuity inspection device, it is possible to suppress a space required for installing a production line of the wire harness 2.

Further, the connector 8 can be held by the wire harness inspection jig 1 only by bringing the connector 8 closer to the opening 24, and the operating portion 33 is pushed toward the outer surface 22 b against the urging force of the coil spring 13. Then, the connector 8 can be removed from the wire harness inspection jig 1. Therefore, the connector 8 can be easily attached to and detached from the wire harness inspection jig 1. Therefore, a decrease in the production efficiency of the wire harness 2 can be further suppressed.
