Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cutting cable conductors.

When connecting cable conductors by welding, it is necessary to provide grooves 11 in the cable conductors 10, 10, as shown in FIG. 1, in order to facilitate the flow of the weld metal and to ensure welding between the weld metal and the conductor.

Conventionally, in order to cut a cable conductor diagonally to create a groove, the conductor was held down by hand.However, since the cable conductor is made of twisted wires, the twist breaks and the cut occurs. There were problems in that the cable conductors were difficult to cut, and a proper cutting angle could not be obtained, and the cross section was uneven, making it impossible to completely weld the cable conductors together later.

The present invention provides a method for cutting a cable conductor that solves the above problems, and includes a cable conductor insertion hole,
A jig having a guide surface inclined with respect to the axis of the cable conductor insertion hole is fixed to the outer periphery of the conductor, and then the conductor is cut along the guide surface.

An embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3, in which 1 is a cable conductor; 2 is a cable conductor 1;
It is a jig fixed to the outer periphery of the

The jig 2 consists of a base body 21 and a lid body 22, both of which are connected by bolts 23. In this connected state, the jig 2 has a cable insertion hole 24 in the center, and has a cable insertion hole 24 along the axis of the cable insertion hole 24. It has a guide surface 25 on one side that is inclined with respect to the guide surface 25. This jig 2 is individually attached to the outer periphery of the cable conductor 1 with bolts 23 so that the guide surface 25 faces the tip side of the cable conductor 1. Thereafter, the cable conductor 1 is cut along the guide surface (in the direction of arrow A in FIG. 2). In the above embodiment, a jig having an inclined guide surface on only one side was used, but a jig having inclined guide surfaces on both sides may be used.

Further, when cutting a hollow cable conductor, it is preferable to insert a pipe or rod into the hollow portion and then cut the pipe or rod together with the conductor along the guide surface.
By using the pipe or rod in this way, deformation of the hollow part can be prevented. Further, the inclination angle of the guide surface is appropriately determined in consideration of the thickness and material of the cable conductor. As explained above, in the cable conductor cutting method according to the present invention, the conductor is cut along the guide surface of the jig, so an appropriate cutting angle can be obtained, and the cut surface of the conductor can be individually defined with the jig. Therefore, it is easy to cut the strands without twisting them, and the cut surface is smooth, which has the advantage that the cable conductors can be reliably welded to each other afterwards.
