Shield wire cutting device and shield wire cutting method using same {CUTTING DEVICE FOR SHIELD WIRE AND CUTTING METHOD FOR SHIELD WIRE USING IT}

The present invention relates to a shield wire cutting device, and more particularly, to a shield wire cutting device that can ensure the quality and improve the productivity by controlling the length of the plurality of shield wire to be cut.

In general, the cable used for the assembly of the vehicle is provided with a coating on the outer surface, in order to be electrically connected to each other, the operation is to remove the coating and cut to a length suitable for assembly.

In removing and connecting the cable, the time taken to remove the cable is considerable. When cutting the cable, the length of each cable to be cut is measured by using a separate tape measure. There is a problem that it takes a lot of time to cut the cable because it must be cut later.

In addition, in order to remove the sheath of the cable, a knife is generally used. In this case, there is a problem that the wire inside the sheath may be damaged during the removal of the sheath because the depth of insertion of the knife into the sheath of the cable is not constant. .

In addition, since the safety device is not provided, the worker frequently injured his hand.

In addition, as the thickness of the cable becomes thicker, it is difficult for an operator to directly remove the sheath using a knife.

In particular, many difficulties occurred in removing the coating during the winter.

Therefore, in order to solve such a problem, as shown in FIG. 1, an apparatus for removing the sheath of a cable has been developed.

Conventional cable sheath cutting device includes a body 10 is formed with a U-shaped guide 12 is inserted into the cable on one side and a cutter 20 hinged to the inside of the body (10). In addition, a portion of the body 10 corresponding to the cutter 20 is formed with a push hole 14 to press the cutter 20.

The process of cutting the sheath of a cable using such a conventional cable sheath cutting device is as follows.

The depth at which the cable is inserted into the guide 12 is inserted by the length of the sheath to be cut.

Then, when the cutter 20 is pressed with a constant force through the push hole 14, the cutter 20 cuts a part of the sheath, and in this state, the entire sheath is cut by rotating the cable.

Then, when the cable is held by one hand and the body 10 is pulled by the other hand, the coating is peeled off and the cutting of the coating is completed.

However, in the conventional coating cutting device as described above, since one side of the guide 12 is open, the cable may be separated from the guide 12 while removing the coating of the cable.

In addition, it is inconvenient because the operator has to press the cutter 20 directly while the cable removing operation is performed.

In addition, since the operator has to cut the sheath of the cable after measuring the length using a tape measure to measure the sheath length of the cable to be cut, there is a problem that a lot of time is required for the work.

Therefore, there has been a demand for the development of a cable cutting device that can more easily remove the sheath of the cable and shorten the time required for cutting, and at the same time prevent the safety accident of the operator.
