Coaxial cable structure and production and application methods thereof

Abstract

The invention discloses a coaxial cable structure, which sequentially comprises a conductor wire core, an insulated foaming layer and a metal shielding layer from inside to outside, wherein a first coating layer is arranged between the conductor wire core and the insulated foaming layer and is the coating layer of a PE material; a second coating layer is arranged between the insulated foaming layer and the metal shielding layer and is the coating layer of the PE material; a sealing layer coats the outside of the metal shielding layer and is made of an ABS plastic material; and the thickness ofthe sealing layer is 15-20 microns. The sealing layer coats the outside of the metal shielding layer, so that the storage time of the coaxial cable structure can be effectively prolonged, the application flexibility is improved, oxidative deterioration or even scrapping is avoided and the material cost is reduced. The invention further discloses production and application methods of the coaxial cable structure.

Description

technical field [0001] The invention relates to the field of coaxial cables, in particular to a coaxial cable structure and its manufacturing and usage methods. Background technique [0002] The structure of the coaxial cable is a conductor core, an insulating foam layer, a metal shielding layer and a sheath from the inside to the outside. In order to prevent the scale-like surface of the insulating foam layer from affecting the performance of the cable, a cladding layer is provided between the conductor core and the insulating foam layer, and between the insulating foam layer and the metal shielding layer. During the production process of the cable, the conductor core is covered with various materials layer by layer, and finally made into a coaxial cable. [0003] The problem is that due to the consideration of the application environment, service life and cost of coaxial cables, PE (polyethylene), PVC (polyvinyl chloride), PUR (polyurethane), XLPE (cross-linked polyethyle...

AI Technical Summary

Problems solved by technology

The problem is that the metal shielding layer is exposed to the air for a long time, and the metal will be oxidized and rusted due to the oxygen and moisture in the air, resulting in a decrease in the quality and performance of the cable, and it can only be scrapped and destroyed.
