After that, the present invention relates to a method for manufacturing a wire harness that is optimal for manufacturing the wire harness by performing the main binding process.

[0002]

2. Description of the Related Art Generally, a wire harness is an electric wiring system having a large number of electric wires, for example, 400-
It is not uncommon to have a circuit count of 500. When manufacturing such a large-scale wire harness, a plurality of unit electric wire bundle assemblies called a temporary binding circuit are manufactured, and they are electrically connected by various means in a step called a main binding step. The method is widely adopted (see, for example, Japanese Patent Publication No. 2-21107).

The temporary binding circuit includes post-insertion terminals for various design reasons. The post-insertion terminals are terminal fittings that are respectively fixed to the ends of a plurality of electric wires that form the wire harness, and the post-insertion step (the step of permanently binding the temporary binding circuit or the wire harness is connected It is attached to the connector during the process of connecting the wire harness to the desired device. In other words, the post-insertion terminal is in a bare state in which it is fixed to the end portion of the electric wire before the post-insertion step is performed.

The post-insertion terminal has various necks in the manufacture of the wire harness because the arrangement when the post-insertion terminal is connected to the connector at the time of main binding is not specified. That is, the process of permanently binding the temporary binding circuit is not currently automated. Therefore, the operator needs to manually insert the corresponding post-insertion terminal into the connector. At this time, the worker has to manually insert the post-insertion terminals while checking the poles of the connector into which each post-insertion terminal is to be inserted, because the arrangement of the post-insertion terminals is not specified. It was a cause of incorrect connection.

This is because there is no point in conducting a continuity check because the terminal fitting is not specified for any pole.

In addition, the post-insertion terminal itself has a problem that it is easily deformed during transportation. Needless to say,
If the terminal is deformed, it becomes difficult to mount the terminal on the connector, or there is a problem such as poor conduction. In addition, there is a problem that the electric wire portion to which the post-insertion terminal is fixed is easily entangled with other electric wire portions and is difficult to handle. The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing a wire harness that can more efficiently perform main binding of a temporary binding circuit having post-insertion terminals.
