BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core wire supplying device for a multi-core cable in a terminal crimping device for crimping and attaching a terminal to a strip of each core wire in a multi-core cable.

[0002]

2. Description of the Related Art In general, a terminal crimping apparatus forms a strip by stripping an end of an electric wire, and crimps a terminal to the strip for mounting.

However, recently, for example, a multi-core cable has begun to be used for wiring of an automobile, and the multi-core cable has a plurality of coated cores formed by peeling an outer coating at an end thereof. Although it has already been proposed to form each strip on each strip and crimp and attach each terminal to each strip, terminal crimping means for crimping each terminal to each core wire of a multi-core cable is performed manually. .

A terminal crimping apparatus of this type which has been already proposed is configured as shown in FIG.

In FIG. 4, a main body 3 of a terminal crimping device 2 is provided on a top surface 1a of a flat machine base 1 of the terminal crimping device, and an anvil 4 is provided below the main body 3. An elevating body 5 having a crimping mechanism is attached to the main body 3 immediately above the anvil 4 so as to crimp the terminal t while separating the bridge of the chain terminal n from the strip w0 of the electric wire w. The upper part 3a of the main body 3
Is provided with a stand 6 integrated with a mounting base 6a, and a boss 7a of a support shaft 7 is provided on an upper portion of the stand 6.
Is rotatably mounted on the shaft. Further, a terminal reel 8 having a chain terminal n is detachably mounted on the support shaft 7, and the chain terminal n of the terminal reel 8 is transferred onto the anvil 4.

Therefore, in the above-described terminal crimping device, the lifting / lowering body 5 having the crimping mechanism is provided in advance with the strip w of the electric wire w.
1, the terminal t is placed on the anvil 4 while the bridge of the chain terminal n is cut off, and the terminal t is crimped to the strip w0 for the co-operation of the lifting body 5 and the anvil 4.

[0007]

However, the above-mentioned terminal crimping device for crimping each terminal to each core wire of the multi-core cable is apt to be an uneven crimp terminal due to the manual operation, and impairs the quality. It is difficult to save labor by mass production.

SUMMARY OF THE INVENTION An object of the present invention is to provide a core wire supply device for a multi-core cable which eliminates irregular crimp terminals and improves quality and saves labor by mass production. And

According to the present invention, there is provided a terminal crimping apparatus having a strip mechanism for forming a strip on an electric wire and crimping a terminal to the strip by crimping. A pair of substrates are mounted on a substrate on the front side of the terminal crimping apparatus. The guide rails are arranged side by side in the front-rear direction, and a moving body is provided slidably in the front-rear direction on both guide rails, and a bracket provided with a cable gripper is erected on the moving body, and the bracket is mounted on the bracket. A core wire holding member is intermittently rotatably mounted on a shaft, and a core wire erecting device is provided on a movable body in front of the bracket so as to incline the erecting core wire. It is provided to stand up.

[0010]

According to the present invention, the end portion of the multi-core cable from which the outer coating has been peeled off and the respective core wires have been stripped in advance is gripped by a cable gripper, and the respective core wires are respectively inserted into the respective insertion grooves of the core wire holding member. Inserting and placing, and then moving down the moving body to the terminal crimping device side to a predetermined position and stopping while horizontally laying the core wire standing up by the core wire crimping device, and forming a strip with this terminal crimping device. The terminal is attached to the strip by crimping, and then the core wire erecting device raises the fallen core wire so as not to hinder other crimping operations, and intermittently rotates the core wire holding member by one pitch. The following core wire standing upright with the above core wire laying device is repeatedly laid horizontally while repeatedly forming a strip and crimping the terminals to the strips and attaching them to eliminate uneven crimp terminals to improve quality and mass production. By ministry It is intended to achieve the reduction.
