Description of the Related Art A manufacturing process of a wire harness constructed by bundling a plurality of covered electric wires includes measuring and cutting the electric wire length, peeling a wire end, and peeling the end of the electric wire. A terminal crimping step of crimping the terminal to the conductor, a terminal inserting step of inserting the terminal into the connector housing, and a bundling step of binding the electric wires to which the connector housing is attached.

[0003] Conventionally, in the above-mentioned terminal inserting step, FIG.
As shown in FIG. 3, the end portion of the electric wire A and the electric wire crimping portion B1 of the terminal B crimped to the end portion of the electric wire A are connected to each other by the electric wire holding claw 1
01 and the terminal holding claw 102 respectively, the terminal holding port 101 faces the terminal insertion opening of the connector housing C, the holding claws 101 and 102 are brought close to the connector housing C, and the tip of the terminal B is connected to the connector. When the terminal B is inserted into the housing C and the terminal B is inserted into the connector housing C to some extent, the pinching of the terminal B by the terminal pinching claw 102 is released, and the terminal pinching claw 102 is retracted upward. Further, the electric wire holding claw 101 is brought closer to the connector housing C, and the terminal B is inserted into a predetermined position of the connector housing C (for example, see Japanese Patent Laid-Open No. 1-313872).

[0004]

According to the above-mentioned conventional terminal insertion technique, as a method of holding the terminal B, the terminal holding claw 10 is used.
Since the method of holding the terminal B by 2 is adopted, the terminal B can be held without replacing the terminal holding claw 102 even if the size or shape of the terminal B is changed. Therefore, there is an advantage that the terminal B can be generally introduced into the connector housing C regardless of the type of the terminal.

However, in the terminal crimping process,
The tip of the terminal B may bend up (see the alternate long and two short dashes line in FIG. 23) and bend down. When such a deformation of the terminal occurs, the core between the tip of the terminal B and the connector housing C may be lost. Due to the displacement, and the small gap between the two, the terminal B cannot be inserted into the connector housing C at all, or even if it can be inserted, depending on the type of the connector housing C, a step portion or the like in the connector housing C may be inserted during insertion. There was a problem in that the tip of the terminal B abuts against and the insertion failure occurs.

Even when the end portion of the electric wire A is bent, the terminal B is misaligned while the terminal B is being inserted into the connector housing C only by the electric wire holding claws 101, and the connector B is misaligned. There is a problem that the tip of the terminal B abuts on a stepped portion or the like in the housing C, resulting in defective insertion. The present invention has been made in view of the above problems, and it is possible to prevent terminal insertion failure due to deformation of the terminal in the terminal crimping step, bending of the end of the wire, or the like. An object is to provide a guide device.
