[0002]

2. 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.

Conventionally, in the above terminal inserting step, a terminal inserting device for automatically inserting a terminal into a connector housing has been used. As shown in FIG. 19, this terminal insertion device includes an end portion of the electric wire A and a terminal B crimped to the end portion of the electric wire A in a state where the end portion of the electric wire A is held by a clamp means (not shown). After the electric wire crimping portion B1 is sandwiched by the electric wire clamping claw 101 and the terminal clamping claw 102, respectively, the tip of the terminal B is exposed to the terminal insertion opening of the connector housing C, and the clamping claws 101, 102 are removed. The tip of the terminal B is inserted into the connector housing C by approaching the connector housing C, and when the terminal B is inserted into the connector housing C to some extent, the pinching of the terminal B by the terminal pinching claws 102 is released. , The terminal holding claw 102
Is retracted upward, and the electric wire holding claw 101 is brought closer to the connector housing C to insert the terminal B into the terminal insertion space of the connector housing C (for example, see Japanese Patent Laid-Open No. 1-313872).

[0004]

According to the above-mentioned conventional terminal insertion device, 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.

However, in the above terminal inserting device, when the electric wire A and the terminal B are clamped, the electric wire A is held by the clamp means, but the terminal B is in a free state, so that the end portion of the electric wire is Terminal B due to bending, etc.
The position of is likely to fluctuate, a misalignment may occur between the clamped terminal B and the connector housing C, and a defective insertion of the terminal B may occur. For this reason, a centering device that measures the amount of misalignment generated by the sensor while the electric wire A and the terminal B are sandwiched and automatically aligns the terminal B and the connector housing C is indispensable. There is a problem that the structure is complicated and the cost is high.

Further, in the terminal crimping process, the tip of the terminal B may bend up (see the chain double-dashed line in FIG. 19) or bend down. Since the holding claw 102 holds the electric wire crimping portion B1 of the terminal B, misalignment may occur between the terminal B and the connector housing C, resulting in defective insertion of the terminal B. In such a case, the aligning device described above is indispensable.

Further, when the end portion of the electric wire A is bent, depending on the type of the connector housing C, the terminal B
Even if the connector housing C and the connector housing C are aligned, when the terminal B is inserted into the connector housing C only by the wire holding claws 101, the bending of the electric wire A causes the terminal B to be biased and the inside of the connector housing C There is also a problem that the tip of the terminal B hits the terminal locking claw or the like, resulting in defective insertion.

The present invention has been made in view of the above problems, does not require the aligning device described above, can reduce the cost, and can surely insert the terminal into the connector housing. An object is to provide an insertion device.
