Compression-resistant composite cable

Abstract

The invention discloses a compression-resistant composite cable. The cable comprises a cable sheath layer, and more than one protruding first convex part is arranged on the outer surface of the cablesheath layer in a protruding manner by surrounding the cable sheath layer by a circle. A circular cavity is formed at the center of the cable sheath layer, and the inner wall of the circular cavity ofthe cable sheath layer is provided with more than one second protruding part around the circular cavity by a circle in a protruding manner. Each first protruding part is exactly opposite to one second protruding part. A first clamping opening is formed in the middle of each first protruding parts, and a second clamping opening is formed in the middle of each second protruding parts relative to the first clamping opening, wherein the open ends of the two clamping openings are oppositely arranged to form a closed clamping cavity, a cable core wire is installed in each clamping cavity, and a closed opening is formed at the side, away from the corresponding first protruding part, of each second protruding part. The cable has multiple compression-resistant and shearing-resistant protection structures, can greatly improve the protection capability of the cable sheath layer, effectively protects the internal core wire from being directly sheared, and improves the use safety of the core wire.

Description

technical field [0001] The invention relates to a cable, in particular to a compression-resistant composite cable. Background technique [0002] Cables are used in a variety of occasions, but no matter what the occasion is, the exposed and buried cables are long in length and span a long distance, so the outer layer of the cable is often compressed during construction or external extrusion. Due to the poor compressive and shear resistance of the outer coating layer, the cable core wire inside the outer coating layer is also directly sheared and squeezed, which leads to damage to the inner core wire of the cable, which directly leads to damage to the entire communication power system, resulting in serious economic losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compression-resistant composite cable, which has multiple compression-resistant and shear-resistant protective structures, increases the safety ...
