Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for stripping a coating from an intermediate portion of a coated wire.

[Conventional technology]

Conventionally, in order to peel off the coating in the middle of a coated wire, the coating at both ends of the part to be peeled off is cut with nippers, etc., and the coating on the middle part is cut vertically with a cutter knife, etc.K.

[Problem that the invention seeks to solve]

However, since the above-mentioned peeling method involves cutting the coating lengthwise with a cutter knife or the like, it has the disadvantage that it requires a great deal of labor and time when the coated wire is thin or when the portion of the coating to be peeled is long.

The present invention eliminates the above drawbacks.

[Means for solving problems]

The present invention includes a first cutter that makes longitudinal cuts in the covered wire as the covered wire is pulled out in one direction, and a circumferential cut made in the covered wire pulled out from the first cutter. This is a coating stripping device for a coated wire, characterized in that it has a second cutter.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In Figures 1 and 2 (a) ebb)j (c),
The device of the present invention makes a first cut in the length direction of the coated wire.
cutter, and a second cutter that makes circumferential cuts in the coated wire.
It consists of a combination with a cutter.

The first cutter has a pair of arms 1 m long that opens and closes around a shaft 5,
lb, a pair of arms 1a, a plate spring 2 that biases lb in the opening direction, and a semicircular cross section that is provided in a direction perpendicular to the arms 1a and lb and accommodates the coated wire over a certain length range. It consists of opposing grooves 3a, 3b, and a pair of straight cutting edges 4a, 4b provided in the grooves 3a, 3b to face each other along the groove direction.

On the other hand, the second cutter is rotatably supported on a shaft 5 connecting the arms 1a and lb, and has a pair of arms arranged in parallel adjacent to the pair of arms 1a and lb of the first cutter. 5a
, 6b, arcuate cutting edges 7a, 7b provided on opposing edges of the six arms 6a, 6b, and a leaf spring 8 biasing the arms 6a, 6b in the opening direction. 9 is a strut horn that regulates the closing condition of the paired arms 6a and 6b! It is.

In this embodiment, two types of grooves 3m with different diameters are used to remove the coating from two types of coated wires with different diameters.

3b, cutting blades 4a, 4b, 7a, and 7b, but the number of combinations of blades is not limited.

In the example, first, the covered wire to be cut is placed on the groove 3a of the arm 1a shown in Fig. 1, and then the arm 1b is closed and the covered wire is sandwiched between the two arms 1a and lb from above and below. . As a result, the cutting blades 4 a p 4 b pierce the covered wire from above and below. Next, with the covered wire sandwiched in, move 9J to the right in Figure 1! Subtract iqm.

At this time, the coated wire is cut into the cutting edge 4 as shown in Fig. 3(a).
&.

4b, with a cut C1 in the longitudinal direction of the circumferential surface. Next, open the arm 1a shown in Fig. 1, and insert the coated wire into the arm 6m, the cutting edge 6b 7m, ? The two arms 6a and 6b are closed and covered by the cuts of the cutting blades 7a and 7b, and circumferential cuts C2 are made at both ends of the vertical cut C5. At this time, the covered wire is as shown in Figure 3(b).
The state shown in Fig. 3(c) is obtained when the rfIL is removed.
The covering as shown in K is then removed, and the core wire L2 of 11 covered wires is exposed.

Therefore, since the sheathing of the sheathed wire can be cut freely, two sheaths, a ring wire, as shown in FIG. 4(a),
3-terminal T4 by L. The connection between T2 and 13 is shown in the same figure (b).
As shown in 1 coat +il! It becomes possible to connect with L, which simplifies soldering and solves problems such as poor contact.

In addition, as shown in FIG. 6(b), a matrix-like circuit configuration can be easily manufactured, and the wiring of a complicated circuit can be simplified.

〔Effect of the invention〕

- As explained above, the present invention has the effect of not only being able to freely cut off the covering of a covered wire, improving work efficiency, but also simplifying wiring, soldering, etc.
