A kind of elastic high temperature resistant coaxial cable for communication and its inner conductor and shielding layer preparation method

Abstract

The invention provides an elastic high temperature resistant coaxial cable for communication. The elastic high temperature resistant coaxial cable is characterized in that an inner conductor (1), an insulation layer (2), an inner conductor shielding layer (3), an outer conductor shielding layer (4) and a sheath layer (5) which are orderly and radially distributed from inside to outside, a layer of metal copper plating layer is introduced to be the inner shielding layer (3) of an outer conductor at the outer surface of the insulation layer (2) through the method of mechanical copper plating, and the outer conductor shielding layer (4) is a tin plated copper wire braided overall immersion tin layer. The elastic high temperature resistant coaxial cable for communication is in accordance with various performance requirements of a high temperature resistant coaxial cable and is superior to the high temperature resistant coaxial cable and can be widely applied to the field of high frequency band connection wire for radar communication.

Problems solved by technology

Although the emergence of these cable structures has effectively improved the high-frequency data transmission requirements and the anti-interference ability of the cable, and can be used at higher temperatures, there are some shortcomings: poor elastic strength and low tensile strength, which will lead to the use of cables Limited range, susceptible to harsh environments

In practical applications, unrecoverable deformation is prone to affect signal transmission
