Problems solved by technology

[0002] At present, the widely used methods of connecting the RF coaxial connector to the cable shielding layer mainly include crimping and welding. The welding method is mainly used for the connection between the coaxial cable above 6GHz and the RF connector. It has stable performance and a wide range of operating frequencies. wide, but the tin-climbing height caused by soldering directly affects the bending performance of the cable assembly; while the crimping form is only used for RF cable assemblies below 6GHz, the standard crimping jaws or the specified crimping die are used for crimping, which is easy to operate and use It is widely used, but its use frequency range is low, and it cannot meet the increasing performance requirements of cable assemblies
