That is, a terminal (not shown) connected to the end of each electric wire is housed and locked in the connector housing. The insertion inspection is performed by connecting this connector to a connector (not shown) on the continuity checker side. This continuity test is the same as the continuity test of a general wire harness (not shown), for example.

[0012]

However, in the above-mentioned conventional method for processing a battery connection plate, when the connection between a certain terminal 100 and an electric wire is detected as defective in the continuity inspection step, the terminal 100 is not connected. However, since the terminal 100 is insert-molded in the plate body 98 made of a synthetic resin, the crimp-defective terminal 100 cannot be replaced, and in the worst case, the entire battery connection plate 97 must be disposed of as a defect.

Connector) from the connector receiver 77, and lock the cylinder 75.
(FIG. 2) is released, the battery connection plate processed product is taken out, and the support base 45a is returned to the home position.

A pair of left and right battery connection plate processed products are arranged in the longitudinal direction, a plurality of wires 58 are led out from each battery connection plate processed product, and one connector (connector housing 60) is connected to the end of each wire 58. It is stored in a shipping case as an arranged form.

Although the electric wires 58 are crimped to the terminals 6 in the above embodiment, connection means such as pressure welding or welding may be employed instead of crimping.

[0059]

As described above, according to the first, second, and fifth aspects of the present invention, before connecting (crimping) an electric wire to the terminal of the battery connection plate, one terminal to be connected and one terminal are connected. Check the continuity between the two by making contact with the wire and confirm that the continuity is OK.
In this case, the terminal and the wire are connected (crimped),
As in the prior art, after crimping the electric wires to all the terminals of the battery connection plate, a continuity test is performed, and in the case of continuity NG, waste such as discarding the entire battery connection plate is eliminated, thereby increasing the production efficiency. Also, since the movable contacts of the control box move in a preset order to connect the wires and the terminals via the positioning pins, if the order of inserting the terminals with wires into the connector housing is incorrect,
Conduction is NG, erroneous insertion of the terminal is reliably detected, and by correcting the erroneous insertion, the connection between the battery connection plate and the connector can be accurately performed.

According to the third aspect of the present invention, in a state where the terminals are positioned by the positioning pins, the wires can be crimped to the terminals and the intermediate connecting portions of the terminals can be cut at the same time. By inspecting the continuity between the terminal and the electric wire through the positioning pins before cutting, the continuity inspection can be performed easily and quickly and reliably as compared with the case where the continuity inspection is performed after the cutting.

According to the fourth and sixth aspects of the present invention,
After connecting (crimping) one electric wire to one terminal, the next electric wire can be taken out without changing the product number, so that incorrect wiring is reliably prevented.
