Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a method for manufacturing lead wires.

[Background of the invention]

Conventionally, a lead wire manufacturing method involves inserting a cutter into the sheathing portion at the end of the cut-off insulated wire, cutting off the sheathing portion at the end from the core wire of the wire 7, exposing the core wire at the end, and then removing the core wire. The parts were soldered to a predetermined object using gold.

However, in such conventional methods, it is difficult to reliably hold the terminal end of the wire at the stage of stripping the wire, making it difficult to strip the wire continuously. However, it had the disadvantage that it was not suitable for automating the work.1.A. Also, since the terminal sheathing was separated from the wire, there were disadvantages such as peeling of the part to be hammered.

[Purpose of the invention]

The purpose of the present invention is to eliminate the drawbacks of the prior art described above,
It is an object of the present invention to provide a method for manufacturing a lead wire in which coating removal from a covered electric wire can be carried out in a continuous optical manner and the work process can be automated.

[Summary of the invention]

In order to achieve all of the above objects, the present invention 1 focuses on the fact that the covering of the covered electric wire is made of a material such as vinyl,
First, only the sheathing is cut, and then the sheathing is compressed along the length of the wire using the insulation properties of vinyl to expose the core wire of the wire. After cutting the core wire, It is used to add half a yo to something.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

Figure 1 is a sectional view showing the state before stripping, and Figure 1 is a cross-sectional view showing the state before stripping.
The figure is a sectional view showing the stripping cutter in an open state, and FIG. 6 is a sectional view showing the state in which stripping is completed.

In each figure, 1 is the core wire of the covered wire, 2 is the +YD
'? The covered portion of the lf wire, 3.4, is a strip cutter, and 5 is a core wire cutting cutter.

As shown in Fig. 1, the stripping cutter is in close contact with the insulated wire that has been stretched to some extent.

4 cuts only the covering portion 2 of the covered wire.

The stripper cutter 3.4 has a structure in which all round cutouts having a diameter slightly larger than the diameter of the core wire 1 are provided so as not to damage the core wire 1.

Next, as shown in Fig. 2,
Push 4 left and right with an air ring, etc. 1. ．． ．． i:”II
G-If I do that, I'll see where the Hiroichi Line is.

In this state, as shown in FIG. 5, (i) Release the IJ knob canters 5 and 4, and cut the exposed center of the core wire portion 1 with another core wire cutting cutter 5. At this time, the shortened "e"
t 5 flB 761. Although it returns to its original state a little, only the pushed-out shins cannot return, so the core wire portion 1 protrudes from the covering portion 2. In this way, the lead wire is completed.

Furthermore, although not shown in the figure, the cut core wire portion 1
The end of the lead wire is soldered to a predetermined location on an electrical device, etc., and the lead wire is fixed in a continuous manner.

〔Effect of the invention〕

According to the present invention, the coating can be removed in small pieces without cutting off the covered wire during a series of operations, and there is no peeling residue of the coating, and furthermore, the coating stripping process can be performed continuously. Since it can be operated, it has the effect of automating work.
