DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire stripper for stripping a coated electric wire used for wiring work of electric and electronic equipment and for assembling electric and electronic parts used in the same, and more particularly. The present invention relates to a wire stripper which can easily peel off an electric wire, which is difficult to peel off without heating, by high-frequency heating.

[0002]

2. Description of the Related Art Conventionally, handy type and electric type wire strippers of this kind are commercially available. Generally, handy type wire strippers have a base end side as a grip portion and a front end side as a blade portion. A pair of rods are crossed and pivotally mounted on a pivot shaft so as to be openable and closable, and a plurality of semicircle-shaped peeling portions are respectively formed at portions opposed to the respective blade portions. The semi-circular shape is sequentially changed in size according to the size, and when the pair of gripping rods are gripped and closed, the blade portion is also closed, and the plurality of peeling portions formed on the blade portion are It is an apparently circular shape, and the insulated wire is placed on the peeling part with the end side open and the gripping part is closed to tighten the blade part, and the wire is pulled by the pressure at the peeling part. The coating is peeled off.

[0003] The electric type wire stripper is
The insertion hole provided in the box-shaped case is provided with a blade portion at the back, and the blade portion has a peeling portion, and the insertion portion of the sheath of the coated electric wire is inserted into the insertion hole and pulled toward the user. It can be peeled by the peeling part only by itself.

[0004]

However, depending on the type of the coating agent coated on the electric wire, there is a coated electric wire which cannot be easily peeled off without heating, and when the coating is peeled off by a conventional wire stripper, the coating of the coated electric wire is difficult. This is a situation in which a peeled portion is immersed in a molten solder bath and heated, or is heated and peeled by a heater or the like.

[0005]

DISCLOSURE OF THE INVENTION In view of the above-mentioned problems, the present invention has been made as a result of diligent studies and, as a result, a wire stripper for inserting a covered electric wire through a peeling portion provided on a blade portion to peel off the coating. And a high-frequency heating coil electrically connected to the high-frequency current generator so as to include the stripped portion of the covered electric wire inserted through the coil.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wire stripper in which a stripped portion of a coated electric wire inserted into a stripped portion of a blade portion of a wire stripper is heated at a high frequency to facilitate stripping of the coated wire. It is.

[0007]

The wire stripper of the present invention is provided with the high-frequency heating coil so as to include the stripped portion of the sheath of the coated electric wire inserted through the stripped portion of the blade portion. It is heated, and then the coated wire is peeled off by being pressed and pulled at the peeling portion, thereby significantly improving workability.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a wire stripper according to an embodiment of the present invention.

FIG. 1 is a front view for explaining an embodiment of the handy type wire stripper of the present invention, and FIG. 2 is a plan view for explaining an embodiment of the handy type wire stripper of the present invention. FIG. 3 is a main part explanatory view for explaining the concept of the embodiment of the wire stripper of the present invention.

[0010] The present invention relates to a wire stripper 1 for stripping a coated electric wire used for wiring work of electric and electronic equipment and assembling work of electric and electronic parts used for the same. The present invention relates to a wire stripper 1 that can easily peel off an electric wire A, which is difficult to peel off without heating, by high frequency heating.
And a high-frequency heating coil 2 electrically connected to a high-frequency current generator so as to include a stripped portion of the coated electric wire A inserted into the stripping portion 1b. It is a thing.

That is, as shown in FIGS. 1 and 2, the embodiment of the wire stripper 1 according to the present invention can be applied to a conventional handy type wire stripper 1, and the wire stripper 1 has a base end. The pair of gripping portions 1c on the side and the pair of blade portions 1a on the tip side are crossed and axially attached by a pivot shaft 1d.
By gripping and opening and closing c, the pair of blade portions 1a are also opened and closed with the pivot shaft 1d as a fulcrum.

Each of the blades 1a is provided with a tapered portion at the opposite end thereof to form an acute angle side, and the acute angle side is formed with a semicircular peeling portion 1b. 1
b is a plurality of stripped portions 1b having different sizes so as to match the size of the insulated wire A to be stripped. The pair of blades 1b are closed to join together to form an apparently circular hole. It becomes.

Next, when the covering of the covered electric wire A is peeled off using the handy type wire stripper 1,
The blade part 1a is opened by opening the grip part 1c, and the blade part 1 is opened.
A size is set from among the semicircular peeling portions 1b formed on the acute angle side of a, the peeling portion of the coating of the coated electric wire A is protruded and placed, the gripping portion 1c is closed, and the pair of peeling portions 1b is closed. The insulated wire A is pulled by being pinched.

The blade portion 1a of the wire stripper 1 of the present invention
Is provided with a high-frequency heating coil 2 so as to include the stripped portion of the coating of the coated electric wire A inserted into the stripped portion 1b, and a high-frequency current generator (shown in FIG. No.) to heat the exfoliated portion of the sheath of the insulated wire A by passing a high-frequency current.

The high-frequency heating coil 2 can be attached to the blade portion 1a of the wire stripper 1 by a clip (not shown). The fixing portion 2a may be provided and fixed to the blade portion 1a by the fixing portion 2a. As shown in FIG. 3, the peeling portion of the coating of the covered electric wire A placed on the peeling portion 1b is included. It is to be mounted so that

Next, as shown in FIG. 3, the electric wire stripper is provided with a blade 1a at the back of an insertion hole (not shown) provided in a box-shaped case. The peeling portion 1b is provided simply by inserting the peeling portion of the insulated wire A and pulling it forward.
Is to be peeled off.

In this case, too, the high-frequency heating coil A is inserted so as to include the stripped portion of the insulated wire A inserted into the stripped portion 1b.
Is electrically connected to the high-frequency current generator.

That is, a high frequency is generated by passing a current through the high frequency heating coil 2, and the blade portion 1 a of the wire stripper 1 is formed.
When the exfoliated portion of the insulated wire A is inserted through the high-frequency heating coil 2 and placed on the exfoliated portion 1b of the wire A, heating is performed by high frequency. In this case, heating is performed from the surface of the metal wire in the electric wire A. The heating can be performed in a short time, and the temperature of the contact surface between the surface of the metal wire and the inside of the coating becomes high, which facilitates peeling.

[0019]

According to the present invention, the high frequency heating coil is provided on the blade portion of the wire stripper according to the above-described configuration, so that the heating starts from the surface of the metal wire of the covered electric wire.
It can be heated in a short time, furthermore, the temperature between the surface of the metal wire and the inside of the coating becomes high, which facilitates peeling, and improves the workability of the peeling operation of the coated electric wire, This is a revolutionary and highly practical invention.
