Shielding-preventive and moisture-proof data cable

Abstract

The invention discloses a shielding-preventive and moisture-proof data cable. The cable comprises conductors, insulating layers, copper-plastic composite belt shielding layers and outer sheaths; three conductors are arranged in the cable; each conductor is formed by combining a plurality of cores; the sections of the conductors are of a circular structure; three water stopping filling strips are arranged in each conductor; every two conductors are connected and fixed through a PVC plastic connecting rod; a plurality of optical units are arranged in a central clearance area among the three conductors; fillers are arranged in clearance parts between the conductors and the optical units; insulating layers are extruded at the outer parts of the conductors; elastic filling strips are arranged in the clearance parts between the insulating layers and the conductors; armored layers, the copper-plastic composite belt shielding layers and reinforced knitting layers are extruded on the outer surfaces of the insulating layers from inside to outside in a sequence; toughening layers are arranged at the outsides of the reinforced knitting layers; a seamless wrinkled knitting sleeve and each outer sheath are arranged at the outside of each toughening layer. The cable has the advantages of being great of insulating effect, high in shielding performance and long in service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-shielding and moisture-proof data cable. Background technique [0002] At present, with the development of science and technology, both industry and human daily life are developing in the direction of electrification. Cables are widely used in industry and power fields. The existing cable structure includes multiple conductors, wrapping The insulating layer, braiding layer, and sheath covering each conductor are composed of several parts, but the anti-interference performance and signal fidelity of the cable with this structure are poor, and it is easy to cause signal distortion, so the signal transmission is not stable enough. , the clarity of the transmitted image is also difficult to meet the requirements of high-definition, and the existing cable moisture-proof performance is not very good, it is easy to be oxidized, and the patent application number published in the Chinese pat...

[0002] At present, with the development of science and technology, both industry and human daily life are developing in the direction of electrification. Cables are widely used in industry and power fields. The existing cable structure includes multiple conductors, wrapping The insulating layer, braiding layer, and sheath covering each conductor are composed of several parts, but the anti-interference performance and signal fidelity of the cable with this structure are poor, and it is easy to cause signal distortion, so the signal transmission is not stable enough. , the clarity of the transmitted image is also difficult to meet the requirements of high-definition, and the existing cable moisture-proof performance is not very good, it is easy to be oxidized, and the patent application number published in the Chinese patent literature is CN201320601054.4 An insulated shielded control cable , it is composed of an insulating core layer, a shielding layer and a sheath. Its structure is a shielding layer made of polyvinyl chloride and a sheath made of flame-retardant polyvinyl chloride. In an environment where the cable has been corroded for a long time, its service life is short and cannot meet the long-term needs of people. Once the cable sheath is broken, it will have a great impact on the entire cable structure, and the insulation is poor. And it cannot play the effect of waterproof and moisture-proof, and cannot meet the existing people's needs for cables.
