Description

Feeding cable cutter {Cutting tool for electric cable}

The present invention relates to a feed cable cutter, and more particularly, to a feed cable cutter capable of cutting a feed cable and removing a covering of the feed cable.

In general, the feed cable is installed for the purpose of energizing a mobile communication base station, such a feed cable is insulated between two copper wires having a different straight line and the outer diameter portion of the outer copper wire is wrapped around the cover.

The feed cable is cut to a certain length, and after the separate connector is joined to the cut part, it is connected to the communication equipment of each base station. The method of cutting the feed cable is generally used by a worker directly cutting the saw. .

In the case of cutting using a saw, when the feed cable is cut by sawing, the surface of the cut portion is very irregular and rough, and the substance adheres to the outer surface. Since it is not cut in the direction orthogonal to the length direction of the feed cable, it is cut in an oblique shape and additional foreign material removal and finishing work is required, which requires a lot of labor and excessive work time. Even after such a foreign matter removal operation, there is a problem in that foreign matter remains on the cut surface to lower the conduction efficiency of electricity. In addition, since the work to remove the cover using a knife or a scalpel to join the connector after the cutting operation has a problem that the work process is very cumbersome and the work efficiency is deteriorated accordingly.
