Abstract

The invention discloses a low-loss low-standing-wave radio frequency cable assembly. An coaxial cable comprises an inner conductor, an insulating medium layer is arranged outside the inner conductor,an outer conductor shielding layer is arranged outside the insulating medium layer, an insulating protective layer is arranged outside the outer conductor shielding layer, a first chamfer is arrangedat the end of the inner conductor. A second chamfer is arranged at the end of the insulation protection layer, a connector tail pipe is arranged on one side of the connector, a second welding cavity is formed in the connector tail pipe, a guide table is arranged at the head of the connector tail pipe, a guide cavity is formed in the guide table, and the guide cavity is communicated with the secondwelding cavity. A guide step is arranged at the joint of the guide cavity and the second welding cavity, a first welding cavity is formed in the tail end of the connector pin, and a welding observation hole is formed in the bottom end of the first welding cavity. By adopting the structure, the radio frequency cable assembly meets the requirements of low insertion loss, low standing wave and equalphase.

Description

technical field [0001] The invention relates to the technical field of cable assemblies, in particular to a low-loss and low standing wave radio frequency cable assembly. 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 ...
