Semi-flexible radio-frequency coaxial cable assembly and manufacturing method therefor

Abstract

The invention discloses a semi-flexible radio-frequency coaxial cable assembly and a manufacturing method therefor, and relates to the technical field of a radio-frequency coaxial cable. The coaxial cable assembly comprises a connector and the coaxial cable, wherein the inner conductor of the coaxial cable is inserted into the connector; a chamfer is arranged at the end of the inner conductor; the manufacturing method for the coaxial cable comprises the following steps of cutting a cable, removing an insulating protection sleeve on the end part of the cable, an outer conductor shielding layer and an insulating medium to expose the inner conductor; trimming the outer conductor shielding layer and the insulating medium; cutting the inner conductor and making the chamfer on the inner conductor; performing tinning on the inner conductor after the inner conductor is subjected to chamfer processing; enabling the inner conductor to be inserted in the welding cavity of the interface inserting pin of the connector, and enabling the inner conductor and the interface inserting pin to be welded together; enabling the outer conductor shielding layer to be inserted into the interface tail pipe of the connector; enabling the outer conductor shielding layer and the tail pipe of the connector to be welded together; and testing the welded cable assembly. By adoption of the technical scheme, the requirements of low insertion loss, low standing wave and equivalent phase of scientific research production on the cable assembly can be well satisfied.

Description

technical field [0001] The invention relates to the technical field of radio frequency coaxial cable connection. Background technique [0002] The manufacture of radio frequency coaxial cable assemblies develops along with the research, production and manufacturing of microwave communication systems. Realize short-distance transmission of microwave signals between different components and modules in the system. Signals of different frequencies and different application environments have different requirements for transmission cables. The technical indicators involved include: insertion loss, standing wave, phase fluctuation, etc. [0003] With the continuous improvement of microwave communication frequency, the requirements for coaxial cable components are also getting higher and higher. Waves are also a difficult point in the manufacture of cable assemblies. When cable assemblies are used for multi-channel signal transmission, the phase consistency between different cabl...
