Abstract

(57) [Summary] [Purpose] The coating of the coated electric wire can be stripped off with a simple structure, and a wide range of changes in diameter can be accommodated. [Effect] A through hole 3 for inserting a covered electric wire is provided in the metal plate 2, and cutting edges 4 and 4 are formed on both side inclined edges of the through hole 3. Insert the wire and rotate the plate 2 relative to each other, make a cut around the coating, and pull the plate 2 toward the end along the length of the wire to peel off the coating from the cut. The core wire can be exposed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a stripper used for stripping the coating of a coated electric wire.

[0002]

[Prior Art]

 When performing connection work using a coated electric wire, it is necessary to strip the coated end of the coated electric wire for a desired length to expose the core wire, and a stripper is used to strip such a coating. .

A conventional stripper is formed by providing a semi-circular recessed blade that bites into the coating of the covered electric wire at a portion facing the covered electric wire of a pliers-shaped tool, and grips the tool to cover the both concave insertion blades. The tool is moved in the length direction of the wire with the cuts made in the coating, and the coating at the end is peeled off.

[0004]

[Problems to be solved by the device]

 Since the conventional stripper described above is formed on a pliers-shaped tool, the manufacturing cost is high, and the semi-circular recessed blade can only strip the coated wire of the corresponding diameter. There is a problem in that it is necessary to prepare cavities with different diameters in order to cope with changes in the diameter of.

Therefore, an object of the present invention is to provide a stripper whose structure has a low manufacturing cost and which can be stripped over a wide range from large diameter to small diameter covered electric wires.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a plate with a through hole having a pair of inclined edges approaching from one end side that expands toward the other end side, and on both inclined edges of the through hole. It adopts a configuration in which a cutting edge is formed.

[0007]

[Action]

 If the covered wire inserted into the through hole of the plate is pushed toward the narrow side between the slanted edges of this through hole, the blade bites into the cover, and if the covered wire and plate are rotated relatively in this state. A cut is made on the entire circumference of the coating, and if the plate is pulled in the length direction of the coated wire, the coating will come out from the cut and the core wire will be exposed.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the stripper 1 is provided with a pair of tilts that approach each other from one end side to the other end side in the central portion along the length direction of the metal plate 2 formed in a substantially rectangular shape. The through hole 3 having a beveled edge is provided, and the cutting edges 4 and 4 are formed on both side inclined edges of the through hole 3.

In the illustrated case, the through-hole 3 is provided with a rectangular large-diameter portion 5 and a V-shaped notch 6 in which the wide-side end is connected to the large-diameter portion 5, and both side edges of the notch 6 are formed. A straight inclined line is formed, and the cutting edges 4 and 4 are provided on the entire length of this inclined edge, but the invention is not particularly limited to such a shape, and the large diameter portion may be a circle or a V-shaped notch. It may be only the part 6.

The stripper 1 of the present invention has the above-mentioned configuration, and in order to peel off the coating B of the coated electric wire A, the electric wire A is inserted into the large diameter portion 5 of the through hole 3 of the plate 2, If A is pushed into the notch 6, as shown in FIGS. 2 and 3, the cutting edges 4 and 4 on both sides with respect to the coating B are bited, and if the plate 2 and the electric wire A are relatively rotated in this state. A continuous cut is made on the entire circumference of the covering B, and if the plate 2 is moved toward the end in the length direction of the covered electric wire A as shown in FIG. The portion of B on the end side from the cut runs out along the core wire C, and the end portion of the core wire C is exposed.

Since the through hole 3 provided in the plate 2 has a structure in which the blade edges 4 and 4 are provided on the V-shaped inclined edge, the covered electric wire A is attached to the blade edges 4 and 4 at a position corresponding to its diameter. The coating B can be peeled off in a wide range from large diameter to small diameter.

Therefore, even when the covered electric wire has a multi-core structure, the large-diameter outer covering and the small-diameter inner covering can be peeled off by one stripper.

[0014]

【effect】

 As described above, according to the present invention, since the cutting edges are formed on the inclined edges on both sides of the through hole provided in the plate, the stripping range is wide from large diameter to small diameter. Can respond to changes in.

Further, since only the through holes are provided in the plate, the structure is extremely simple, and it is possible to manufacture and provide at a low cost.
