Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable sheath stripping tool, and more particularly to a cable sheath stripping tool suitable for stripping the insulation of a crosslinked polyethylene cable.

When connecting and terminating cables, the plastic insulation and other coverings are stripped off to expose the conductors.

Various cutting tools have been devised for stripping off the coating, but all of them have the drawbacks of being large and complex due to the large number of component parts, and being expensive.

The present invention was made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a cable sheath stripping tool that has a simple structure and is inexpensive.

Hereinafter, the present invention will be described with reference to illustrated embodiments.

In FIGS. 1 and 2, the stripping tool, designated as a whole by reference numeral 1, includes a pair of gripping bodies 2at2b arranged opposite to each other and a screw rotatably attached to one end of each of these gripping bodies 2a and 2b. It includes rods 3a and 3b and a cutter 4 located in the middle of one gripper 2b.

The gripping bodies 2a and 2b are provided with square grooves 6a and 6b on their opposing surfaces into which the cable 5 to be coated can be inserted.

The threaded rod 3a is rotatably mounted on the gripper 2a, and is connected to the other gripper 2b by screwing into a screw hole 7a provided in advance.

The other threaded rod 3b is similarly rotatably mounted on the gripping body 2b, and is screwed into the threaded hole 7b of the opposing gripping body 2a.

The threaded rods 3a, 3b extend to the outside of the grips 2a, 2b, and the extended portions 8a, 8b function as handles to be described later.

Pins 9a, 9b are implanted in the threaded rods 3a, 3b to prevent them from coming out from the grips 2a, 2b.

The cutter 4 is fitted into a holder 10 that protrudes in the length direction of the cable 5 at the intermediate portion of the grip 2b, and is fixed by a set screw 11.

Therefore, by loosening the set screw 11, the cutter 4 can move forward and backward toward the other grip body 2a.

Note that the cutting edge 12 of the cutter is opposed to the axis of the cable 5 held between the gripping bodies 2a and 2b.

Next, a method of using the stripping tool 1 having the above structure will be explained.

In FIG. 1, first, the threaded rods 3a and 3b, that is, the handles 8at8b, are rotated so as to move to the outside of the gripping bodies 2at2b, thereby widening the distance between the two gripping bodies 2at2b, so that the insulator end face 13 of the cable 5 is Insert it at position 1 where it contacts the cutting edge 12a.

Next, the threaded rod 3at3b is rotated in the opposite direction to sandwich the cable 5 and lightly tighten it.

Next, the cutting edge 12 is set at a position where it almost contacts the conductor 14 of the cable 5, and is fixed with a set screw 11.

Now that the preparations are complete, remove the stripping tool 1 in the state shown in Figure 1.
By rotating clockwise, the cutter 4 can continuously cut the insulator of the cable 5 in the length direction.

According to the above embodiment, since the number of types of parts is small and the shape is simple, it can be manufactured at low cost and the size can be reduced accordingly.

Also, the threaded rod 3a. By rotating the cable 3b, the cable can be disassembled from the grip 2at2b, so that the cable coating can be stripped off at any position on the cable.

For example, when using this tool as an intermediate stripping tool, as shown by the two-dot chain line in FIG.
The cutter 4 is replaced with one having a cutting edge like a so-called parting tool.

When set on the cable, a stable cutting state can be achieved due to the three-point contact between the V-shaped groove of the extended portion 15 of the gripper 2a and the cutting edge of the cutter.

In this state, by rotating the grips 2a and 2b and moving the cutting edge so as to bite into the cable, the cable coating can be stripped off in the circumferential direction, and then the cutting tool can be used as shown in the figure. The cover can be stripped off to a predetermined length as described above.

As described above, the present invention has the advantage that it can be manufactured at low cost because the number of types of parts is small and the shape is simple.

In addition, since the tool of the present invention is provided with a ■-shaped groove into which the cable can be inserted on the opposing surfaces of the pair of gripping bodies, it is possible to stably contact the cable when stripping the cable coating. It is possible to accurately cut the cutting edge into the cable sheath.

Furthermore, according to the present invention, since the threaded rod that connects the pair of gripping bodies and the handle that rotates the gripping bodies are connected, handling from attachment to the cable to tightening of the gripping bodies and rotary cutting is easy. Yes, cutting work can be done efficiently.
