High-elasticity composite cable

Abstract

The invention discloses a high-elasticity composite cable. The cable comprises a circular cable body encircled by more than one cable core, each cable core is wrapped in a metal heat conduction layer,each metal heat conduction layer is wrapped in a PVC coating layer, and the adjacent cable cores make contact with each other via the external PVC coating layers; and an intermediate tube is arrangedin the middle of the cable body, a filling cavity is arranged in the intermediate tube, a water storage hose is arranged in the filling cavity, an enclosed water storage cavity is arranged in the middle of the water storage hose, the input and output ends of the water storage cavity are sealed, elastic metal rods are welded and fixed to the metal heat conductive layers relative to the intermediate circular center direction respectively, and the elastic metal rods all penetrate the intermediate tube and extend into the filling cavity therein. The composite cable has a high elasticity capability and can be applied to diversified occasions, can resist pressure and shearing effectively, and has a high heat radiation performance, and the total service life of the cable is prolonged.

Description

Technical field [0001] The invention relates to the field of cables, in particular to a highly elastic composite cable. Background technique [0002] The current cable structure is generally composed of multi-strand core wires, and then each strand core wire is wrapped with a layer of PVC outer layer for protection. Therefore, once this kind of cable is squeezed, all core wires will be Extrusion, the core wire and the core wire are squeezed and damaged, resulting in a greatly reduced service life of the entire cable, poor compression and shear resistance, poor elasticity, and it is difficult to recover from deformation. Moreover, since the strands of core wires are in close contact with each other and are wrapped in a closed environment, their heat dissipation performance will be greatly reduced, which seriously affects the transmission stability and service life of the cable. Summary of the invention [0003] The technical problem to be solved by the present invention is to prov...

Problems solved by technology

[0002] The structure of the current cable is generally composed of multiple core wires, and then a layer of PVC outer layer is wrapped outside each core wire for protection. Therefore, once the cable is squeezed, all the core wires will be affected. Extrusion, the core wire and the core wire are extruded and damaged, resulting in a greatly reduced service life of the entire cable, poor compression and shear resistance, poor elasticity, and it is difficult to recover from deformation

Moreover, since each core wire is in close contact with each other and wrapped in a closed environment, its heat dissipation performance will be greatly reduced, which will seriously affect the transmission stability and service life of the cable.
