Composite material high and low temperature resistant signal cable

Abstract

The invention relates to the technical field of cables. The invention relates to a cable, in particular to a composite material high and low temperature resistant signal cable. The cable includes a support fill core; a mounting hole is formed at one side of the support filling core; a high-strength tensile rope is fixedly connected to the inner side of the mounting hole; a plurality of uniformly distributed spiral holes are formed in one side of the support filling core; insulating rubber sleeves matched with the spiral holes are fixedly connected to the inner sides of the spiral holes; the inner sides of the insulating rubber sleeves are fixedly connected with wire cores matched with the insulating rubber sleeves, the outer side of the supporting filling core is fixedly connected with ananti-impact layer, the outer side of the anti-impact layer is provided with a net-shaped groove, and the inner side of the net-shaped groove is fixedly connected with an anti-impact net. By arrangingthe high-strength tensile rope, the anti-impact layer, a telescopic rebound layer, an anti-interference layer, a telescopic-resistant layer, a heat-insulating layer and wear-resistant particles, the cable has the functions of high-temperature resistance, low-temperature resistance, breakage resistance, heat insulation, flame retardance, wear resistance and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a composite material high and low temperature resistant signal cable. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several wires or groups of wires. A signal cable is a signal transmission tool. Generally, the signal transmitted by a signal cable is very small. In order to avoid signal interference, there is a layer outside the signal cable. Shielding layer, the signal cable in the prior art has a simple structure and poor high and low temperature resistance. In a high temperature environment, it may cause its internal structure to soften and deform, resulting in short circuit failure of the cable. In a low temperature environment Under the circumstances, the internal wire core may be broken due to thermal expansion and contraction, which cannot be applied to the environment with large temperature changes. Therefo...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art that the signal cable in the prior art has a simple structure, poor high and low temperature resistance, and may cause its internal structure to soften and deform in a high temperature environment, resulting in cable failure. Short circuit failure, in a low temperature environment, may cause its internal wire core to break due to thermal expansion and contraction, and cannot be applied to environments with large temperature changes, and a composite material that is resistant to high and low temperature signals is proposed cable
