A twist-proof coaxial cable

Abstract

The invention relates to the technical field of power cables. The invention further discloses an anti-distortion coaxial cable that comprises a copper core; the copper core is fixedly sleeved with aninner shielding layer on the outside, the inner shielding layer is fixedly sleeved with an inner insulating layer on the outside, the outer side of an outer insulating layer is fixedly sleeved with anouter shielding layer, the outer shielding layer is fixedly sleeved with a protective layer on the outside, one side of the outer side of the protective layer is fixedly sleeved with a fixed sleeve,and the outer side of the fixed sleeve is fixedly sleeved with a connector. The anti-distortion coaxial cable is provided; a sliding block, an annular sliding groove, a sliding block, a telescopic rod, an annular inclined block and an annular clamping groove are matched for use, so the annular sliding groove and the sliding block can slide relatively, and the annular inclined block and the annularclamping groove can slide relatively, such that the fixed sleeve can flexibly rotate in the connector, the protective layer is protected and the surface of the protective layer is prevented from being damaged when the protective layer rotates, and the purpose of preventing the distortions is realized by the anti-distortion coaxial cable.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an anti-twist coaxial cable. Background technique [0002] Coaxial cables can be divided into baseband coaxial cables and broadband coaxial cables in terms of usage, that is, network coaxial cables and video coaxial cables. Coaxial cables are divided into 50Ω baseband cables and 75Ω broadband cables. Coaxial cables and thick coaxial cables, baseband cables are only used for digital transmission, and the data rate can reach 10Mbps. [0003] Aiming at the defects of the existing technology, the Chinese patent (publication number: CN101110283B) proposes a coaxial cable and a multi-core coaxial cable. The advantages of the coaxial cable and the multi-core coaxial cable are that the outer diameter is reduced and the bendability is excellent. , can improve productivity, but there are still the following defects to be solved: because the coaxial cable is exposed and there is no pr...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-twisting coaxial cable, which has the advantages of preventing twisting of joints and cable joints, good corrosion resistance, strong insulation performance and good electromagnetic shielding effect, and solves the problem of coaxial cables. The cable is exposed and unprotected, making it easy for people and moving objects to come into contact with the coaxial cable, making the cable's protective layer vulnerable to twisting and damage when relative rotation occurs between the cable joint and the cable, and Due to the different use of the external environment, the use environment in some areas is highly corrosive and electromagnetic interference is strong. However, the traditional coaxial cable cannot adapt to the problems of these use environments due to its own material.
