Problems solved by technology

On the other hand, the conductor of this kind of cable is twisted by tiny metal wires, so the production of a cable needs to be bundled 4 times, made of insulated wire core 4 times, and sheath extruded once; The production speed is slow, therefore, restricting the production speed

Abstract

The invention belongs to the technical field of electric wires and cables and particularly relates to a four-core cable. The four-core cable comprises four conductors and a sheath layer and is characterized by also comprising a filling body positioned in the center and four isolating bars, wherein the four conductors and the four isolating bars are tightly attached to the filling body and are distributed along the outer circumference of the filling body; a first isolating bar is positioned between a first conductor and a second conductor; a second isolating bar is positioned between the second conductor and a third conductor; a third isolating bar is positioned between the third conductor and a fourth conductor; a fourth isolating bar is positioned between the fourth conductor and the first conductor; the four isolating bars and the sheath layer are integrally molded; the four isolating bars are protruded from the inner wall of the sheath layer to the filling body; on any cross section, the curvatures of the surfaces on which the isolating bars and the conductors are attached to the outer surface of the filling body are equal; and the sheath layer is used for covering the four isolating bars and the four conductors. The four-core cable has the advantages of low consumption of the sheath layer, thinner outer diameter, lower cost in various aspects, simpler production process, higher speed, simple production method and the like.

Description
