Straight high-bending resistance strength cable

Abstract

The invention discloses a straight high-bending resistance strength cable, which comprises a cable center, a second coating layer, a cross linked protective layer and a sheath layer, wherein the cable center internally comprises an elastic support frame; the elastic support frame is composed of an inner cylinder, an outer cylinder and multiple supporting plates radially arranged along the cable center; one end of each supporting plate is located in the inner cylinder and the other end passes out of the inner cylinder and the outer cylinder; the arc-shaped protective piece located at the tail end of the outer side of the outer cylinder of the supporting plate abuts against the inner wall of the second coating layer in a matched mode; multiple wires are vertically arranged between any two adjacent supporting plates and located at the outer side of the outer cylinder and are close to the supporting plates at two sides, the outer wall of the outer cylinder and the inner wall of the arc-shaped protective piece; multiple groups of signal line pairs are respectively vertically arranged between any two adjacent supporting plates and located between the inner cylinder and the outer cylinder; and the cable core is sequentially coated by the coating layer, the cross linked protective layer and the sheath layer. The straight high-bending resistance strength cable is an-extrusion, bending-resisting and simple and stable in structure.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a straight cable with high bending strength. Background technique [0002] After the cable is laid and installed, it is more likely to be squeezed and stretched by the outside world, especially in the process of anti-extrusion, the wire in the center of the cable is easily deformed or even broken, which cannot guarantee the smooth transmission of power and communication, resulting in huge economic losses. Therefore, how to manufacture an integrated cable that is resistant to extrusion and bending, and has a simple and stable structure has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a straight cable with high flexural strength, which has a simple and stable structure and excellent extrusion and bending resistanc...
