Embodiment Construction

[0007] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of a high-strength anti-pressure shielded cable proposed by the present invention.

[0008] refer to figure 1 , a high-strength anti-compression shielded cable proposed by the present invention, comprising: a cable core, an aluminum-plastic composite tape 4 and an outer sheath 5; the cable core includes three wire cores 1, three elastic anti-compression cores 2 and a binding core 3, three The wire cores 1 are arranged vertically in parallel and against each other. On any cross-section, the central connection line of the three wire cores 1 is an equilateral triangle. Shielding layer 12, insulating layer 13, copper tape shielding layer 14, elastic buffer layer 15 and wrapping layer 16, specifically, the conductor 11 is formed by twisting a plurality of copper wires, and the elastic compression core 2 is located between two adjacent wires. Between the cores 1, it has an inner arc surface against th...

Abstract

The high-strength compression-resistant and shielded cable proposed by the present invention includes a cable core, an aluminum-plastic composite tape and an outer sheath; the cable core includes three wire cores, three elastic compression-resistant cores and a bundled core, and the three wire cores are longitudinally arranged in parallel and abut against each other. Rely, on any cross-section, the central connection line of the three cores is an equilateral triangle, and the three cores include a conductor located in the middle, a semiconducting shielding layer, an insulating layer, a copper tape shielding layer, and an elastic buffer layer that are sequentially wrapped around the outside of the conductor. And the wrapping layer, the elastic compression core is located between two adjacent wire cores, it has an inner arc surface that is against the wire cores, and the elastic compression cores cooperate with each other so that the cable cores have a circular cross-section, and the bundled core is located in the In the elastic compression core, it is formed by twisting a plurality of steel wires, the aluminum-plastic composite tape is wrapped around the outer periphery of the cable core, and the outer sheath is extruded and wrapped around the outer periphery of the aluminum-plastic composite tape. The high-strength compression-resistant shielding cable proposed by the invention has a compact structure, is compression-resistant and tensile-resistant, and has good electromagnetic wave shielding performance.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a high-strength compression-resistant shielded cable. Background technique [0002] Electrical equipment includes primary equipment and secondary equipment, and cables belong to secondary equipment in electrical equipment. With the continuous development of our country's economy, the application range of cables is getting wider and wider, and their performance requirements are getting higher and higher. Traditional cables have weak compression resistance and poor electromagnetic wave resistance, which seriously affect the promotion and use of cables. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-strength compression-resistant shielded cable to solve the above technical problems. [0004] A high-strength anti-compression shielded cable proposed by the present invention includes...
