Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric wire/cable sheath stripper capable of stripping a predetermined length of the electric wire/cable sheath from the end of the electric wire.

This device has an insertion hole for the electric wire cable, is equipped with a wire clamping tool consisting of a fixed clamping part and a movable clamping part for gripping the cable at one end, and has a male screw part with a predetermined shaft length carved into the other end. The wire support is screwed into a cutter holder, which has a female threaded part for threading the male threaded part and a slipping cavity part for the male threaded part to rotate on the inner periphery, and a coated cutter facing the exit hole on the same axis as the female threaded part. The wire cable is inserted into the wire support, gripped by the clamping tool, and then the cutter holder is rotated to cut the sheathing of a predetermined length in a spiral shape.
It can be cut off by idling, and the coating can be removed quickly, reliably, and safely.

This invention will be explained below based on embodiments shown in the drawings.

Reference numeral 1 denotes a cylindrical wire support having an insertion hole 6 for a wire cable A, and a wire clamping tool 3 having a fixed clamping part 2 and a movable clamping part 5 that can be freely opened and closed is provided at one end thereof, and at the other end thereof. A male threaded portion 7 with a predetermined axial length N is provided.

In the embodiment, one end of the wire support 1 is cut out in the axial direction to provide a grip 1', which is fixed to the fixed clamping part 2 of the clamping tool 3, and is attached to the other movable clamping part of the clamping tool 3. A gripping body 4 is fixedly attached to the gripper 5, and the electric wire cable A can be gripped by the upper gripping bodies 1' and 4 by gripping the handle of the clamping tool.

The gripping bodies 1' and 4 are provided with arcuate surfaces, ■-shaped surfaces, etc. for gripping the electric wire cable A on opposing surfaces.

Furthermore, although the gripping bodies 1' and 4 are fixed to the fixed clamping part 2 and the movable clamping part 5 with screws, the present invention is not limited to this, and the gripping bodies may be integrally formed with the clamping parts. can.

Reference numeral 10 designates a cutter holder which is rotated by a screwed rotary handle 11, which has a female threaded portion 9 on its inner periphery, an idle hollow portion 12, and an outlet hole 8 on its end surface while maintaining the same axis, and cuts the wire coating on the end surface. The coated cutter 13 is fixed facing the outlet hole 8.

Reference numeral 9 denotes a female threaded portion provided at the axial center of the cutter holder 10, which connects the electric wire cable A between the fixed clamping part 2 and the movable clamping part 5 of the clamping tool 3.
The cutter holder 10 is carved to be longer than the male threaded portion 7 of the wire support 1 to be gripped by the cutter holder 10, and the male threaded portion 7 is screwed into the cutter holder 10.

Reference numeral 12 denotes an idle hollow portion provided at the end of the female threaded portion 9 of the cutter holder 10 so as to maintain the same axis, and has an inner diameter slightly larger than the outer diameter of the male threaded portion 7, and its axial length M is equal to the axial length N of the male threaded portion 7.
It has a slightly longer shape and is provided so that the male threaded portion 7 idles in the idle rotation cavity 12.

Reference numeral 14 indicates a scale for the coating removal length engraved on the outer periphery of the wire support 1.If the cutter holder 10 is set in advance at a desired position on this scale and cutting is started, the coating can be stripped by that scale. can.

B shows the core wire from which the coating has been stripped.

In this device having such a structure, the covered wire cable A is inserted from the clamping tool side of the insertion hole 6 of the wire support 1, and the covered wire cable A is inserted into the insertion hole 6 of the wire support 1, and
After applying the end face of the electric wire to 3, the wire is supported by the clamping part of the clamping tool 3.

Then, when the cutter holder 10 is rotated with the rotary handle 11, the cutter 13 cuts the coating in a spiral shape by the screw feed of the male and female threaded parts 7 and 9, and then the male threaded part 7 idles in the idle hollow parts 1 and 2. , the helically cut coating will be cut off.

In this way, this invention fixes the female screw part 9 of the shaft center of the cutter holder 10 to be rotated and the electric wire A by fixing the clamping part 2 and the movable clamping part 5.
The male threaded part 7 of the male threaded part 7 is screwed to the male threaded part 7 of the wire support 1 held by the cutter holder 10, and after cutting the coating with the cutter 13 by thread feeding, the idle hollow part 12 of the male threaded part 7 is connected to the female threaded part of the cutter holder 10. It is installed at the end of the cutter holder 10 and automatically cuts the coating to a predetermined length just by rotating the cutter holder 10, so the work can be done quickly and reliably, especially when working in high places such as utility poles. can be done safely.

Generally, electric wire cables are coated with strong electrical insulating materials such as polyethylene and vinyl chloride, and it is difficult to strip them off, but with this invention, the work can be done quickly, reliably and safely, making electric wires extremely useful in practice. A cable stripper is obtained.
