Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The method of the present invention relates to a method for deriving an electric wire core.

[Conventional technology]

Conventionally, when connecting electric wires to multiple terminal fittings by crimping, etc., as shown in Fig. 6, a tool such as a stripper is used to strip the coating of the multiple electric wires C one by one to separate the core wires C. I was exposing myself.

[Problem to be solved by the invention]

However, there is a problem in that the work of deriving the core wire C° by stripping off the covering of the plurality of electric wires C one by one as described above is troublesome and takes a long time.

The method of the present invention was devised in view of the above-mentioned problems, and it is an object of the present invention to provide a method that is extremely simple and can lead out the required number of wire cores in a short time.

[Means to solve the problem]

The present invention involves bending an electric wire into a U-shape, cutting the coating at the U-shaped bent end with a sheathing cutter, moving the sheathing cutter to the U-shaped bent end to expose the core wire, and cutting the coating at the U-shaped bent end. This method solves the problems of the conventional method by cutting the wire with a wire cutter.

[For production]

The sheathing cutter cuts the sheathing of the U-shaped electric wire and pulls the cut-off sheathing toward the U-shaped bent end to expose the core wire.

The wire cutter cuts the wire at the U-shaped bent end.

〔Example〕

Examples of the method of the present invention will be described below with reference to the drawings. 1st
Figures 3 through 3 are explanatory diagrams showing one embodiment of the method of the present invention.

In the method of the present invention, first, as shown in FIG. 1, the coating at the U-shaped bent end of the electric wire C is cut by a coating cutter 1, and then the coating cutter 1 is cut as shown in FIG. Move it to the U-shaped bent end to expose the core wire C' of the electric wire C. Next, cut the U-shaped bent end with wire cutter 2.
As shown in FIG. 3, two core wires are simultaneously drawn out.

In addition, although the method of bending one electric wire into a U shape and deriving a core wire has been illustrated and explained above, the method of the present invention is not limited to this, and as shown in FIG. C is bent into a meandering shape, and one or both of the U-shaped bent ends of the core wire C are formed.

Of course, it is also possible to derive the core wire C' by the method described above, or to simultaneously derive the core wire C' by bending a plurality of electric wires C into a U shape as shown in FIG. .

〔Effect of the invention〕

According to the method of the present invention, as described above, the electric wire C is bent into a U shape, the coating at the U-shaped bent end is cut by the coating cutter 1, and the coating cutter 1 is moved to the U-shaped bent end to center the wire. This extremely simple method of exposing the wire C' and cutting the U-shaped bent end with the wire cutter 2 has the excellent advantage of being able to lead out a plurality of wire cores in a short time.
