Flexible light wide-temperature leaky coaxial cable

Abstract

The invention provides a flexible light wide-temperature leaky coaxial cable which is characterized by comprising a cable internal conductor (1), an insulating layer (2), an external conductor (3) and a sheath layer (4) which are arranged from inside to outside in turn. The cable internal conductor (1) and the external conductor (3) are formed by carbon nanotube fiber material. The external conductor (3) is provided with groove holes which are uniform in size. According to the flexible light wide-temperature leaky coaxial cable, an innovative ideal is provided for expansion of use and development of the leaky coaxial cable under the extreme conditions so that the flexible light wide-temperature leaky coaxial cable has great social benefit.

Description

technical field [0001] The invention relates to leaky coaxial cable products in the field of communication transmission, and specifically belongs to a kind of leaky coaxial cable using carbon nanotube fiber material as the inner and outer conductors, using foamed polytetrafluoroethylene as insulation, and using perfluoroethylene propylene Copolymer is a kind of flexible light-weight wide-temperature leaky coaxial cable used under extreme conditions as a sheath, and it is a leaky coaxial cable with ultra-light weight, high temperature resistance and high flexibility. This kind of cable can be used in leaky coaxial cable occasions that require high temperature resistance, light weight and flexibility, and can be widely used in aerospace, ship cabins, concealed military facilities, mines, oil wells, high-speed railways and highways, etc. Space mobile communications in regional or semi-enclosed areas. Background technique [0002] Leaky coaxial cable is referred to as leaky cab...

AI Technical Summary

Problems solved by technology

The raw material generally used for the inner conductor is metal copper wire or copper-clad aluminum wire, the raw material generally used for the outer conductor is copper strip or aluminum strip, and the outer conductor is usually covered on the outer surface of the insulating layer in the form of longitudinal corrugation, or welded The outer conductor structure of the embossing process, due to the physical characteristics of the metal conductor, when the leaking coaxial cable is stressed or bent under pressure, it is easy to cause deformation or collapse of the opening, destroying its structure and affecting performance

In addition, due to the characteristics of its rigid structure, a large gap is formed between the outer conductor and the insulating layer during bending, which is likely to cause the penetration of water vapor and other corrosive gases outside the environment, damage the structure and performance of the cable, and affect the service life. In the process, due to the friction and rigidity of the metal belt, it is easy to cause deformation and fracture of the metal belt, which affects the product quality
