After positioning the cable to a wiring station (not shown), the electric wire 12 is supplied by a wiring head (not shown) that is horizontally movable above the wiring base B, and the supplied electric wire 12 is supplied to the wiring base B. Terminal 1 at the end of the
Crimp 3 The wiring head automatically runs according to a pre-programmed route.

The chain-shaped electric wire clamp C has a large number of electric wire clamps 17 arranged and accommodated in the insertion frame 15 of the support rod 14, and the electric wire clamp 17 has a pair of clamping claws 19 and 19 on an upper portion of a base portion 18. It is provided (see FIGS. 5 and 6). Then, one end of the electric wire 12 to be routed is pushed and clamped into the pair of clamps 19, 19 when passing through the electric wire clamp 17 by the traveling of the wiring head, and the pin 1 of the wiring base B is pinched.
The other end of the electric wire 12 bent and passed by 1 is clamped by the clamps 19 and 19 of another electric wire clamp 17.
Therefore, the wire clamp 17 that holds both ends of the wire 12
The position of must be accurate because it affects not only the position where the electric wire is held by the wiring head but also the wiring length and the binding position of the electric wire 12.

Next, the assembling work of the chain-shaped electric wire clamp C will be described. First, the first clamp stopper 20 (see FIG. 6) is temporarily assembled to one end of the insertion frame 15 of the support rod 14. The clamp stopper 20 includes an upper pressing plate 21 placed on a bending wall 15a (see FIG. 5) that bends inward from the upper end of the insertion frame 15, and a lower reference plate inserted into the insertion frame 15. 22 and a tightening bolt 23 for tightening the pressing plate 21 and the reference plate 22 to the bent wall 15a.

Next, one end of the support rod 14 and the clamp stopper 2 are attached to the backing plate 25 fixed to the end surface of the mounting base 24.
With 0 abutting, the tightening bolt 23 is tightened, and the clamp stopper 20 is tightened to the support rod 14. As shown in FIG. 7, the first electric wire clamp 17 is gripped, the base portion 18 of the electric wire clamp 17 is inserted into the insertion frame 15 from the other end of the support rod 14, and abutted against the reference plate 22. Next, the base portion 18 of the second wire clamp 17 is abutted against the base portion 18 of the first wire clamp 17. Similarly, a large number of electric wire clamps 17 are arranged inside the support rod 14 and accommodated therein, and then the second clamp stopper 20 is fastened to the other end of the support rod 14, which is also the last inserted electric wire clamp. Abut on the base 18 of 17.

[0006]

In the conventional assembly of the chain-shaped electric wire clamp C, as shown in FIG. 7, before the electric wire clamp 17 is inserted into the insertion frame 15, a file is inserted into the insertion opening at the tip thereof. Chamfering is done by using. However, in order to prevent the electric wire clamp 17 from rattling and moving, the electric wire clamp 17 is formed so that there is almost no dimensional difference (clearance) between the outer method of the base 18 and the inner method of the insertion frame 15. It is difficult to insert the clamp 17 quickly and surely from the insertion opening of the insertion frame 15. Therefore, the number of assembly steps is increased and the manufacturing cost is increased, which is a problem.

The present invention has been made in order to solve the above-mentioned problems, and makes it easy to insert the electric wire clamp into the support rod, greatly reduce the number of assembling steps, and reduce the manufacturing cost.
