AI Technical Summary

Problems solved by technology

Most of the corrugated outer conductors currently used are made of copper. Due to the large proportion of the copper strip corrugated outer conductor, the extrusion of the insulation and the inner conductor is relatively large, and it is not convenient for transportation and erection.

Abstract

This invention relates to a kind of coaxial cables including an internal conductor extending along a longitudinal axis, an insulation material, an outer conductor and a jacket orderly placed from inside, in which, said insulation material isolates the internal and outer conductors characterizing that Al ribbon is taken as the backing of the outer conductor, a layer of nickel is plated on the backing and then the copper material is taken as a coating to be wrapped on the Al ribbon.

Description

technical field [0001] The invention relates to the communication field, in particular to a coaxial cable. Background technique [0002] In recent years, global mobile communication technology has developed rapidly, and my country's mobile communication technology has gradually developed from analog systems to GSM and CDMA systems. The construction of a large number of mobile communication base stations has increased the market demand for 50-ohm coaxial cables. Due to the difficulty in manufacturing 50-ohm coaxial cables, there are only a few manufacturers in China. The products produced by different manufacturers have their own characteristics, but the basic principles and technical means adopted are roughly the same. The 50 ohm coaxial cable is mainly composed of four parts: inner conductor, insulation, corrugated outer conductor and sheath. The inner and outer conductors are placed on the same axis, separated by low-loss insulating material to fix the coaxial position of...
