Problems solved by technology

This technical solution can realize various technical performances of ultra-micro-sized coaxial switches, but the part of the movable terminal that provides elastic force needs to be bent into an arched shape, and the bending structure will generate internal stress that cannot be released, resulting in instability
The dynamic and static terminals both adopt a plug-in structure, which makes the assembly process difficult due to their very small size; moreover, 5G technology requires multi-channel transmission of antenna signals, and single-channel coaxial switches cannot meet the requirements of 5G communication technology

Abstract

A coaxial switch, comprising an insulating base provided with at least one terminal groove, a movable terminal and a static terminal fixed in the terminal groove, an insulating upper cover covering the insulating base, and connecting the insulating base to the The insulating upper cover is fixed as a whole metal shell, the terminal slot includes a recessed part and a supporting wall formed at the rear end of the recessed part, the movable terminal includes a first holding part fixed at the front end of the terminal slot, The first holding part extends to the first welding leg on the lower surface of the insulating base and the elastic arm formed by extending backward from the first holding part, the free end of the elastic arm overlaps the upper part of the supporting wall, The static terminal includes a second holding portion fixed at the rear end of the terminal slot, a second solder leg extending from the second holding portion to the lower surface of the insulating base, and a contact extending from the second holding portion. arm. The elastic force of the moving terminal of the coaxial switch of this application is stable.

Description

technical field [0001] This application relates to the field of electrical connectors, especially a coaxial switch. Background technique [0002] Coaxial switches are widely used in mobile devices for testing antenna signals, generally including upper and lower plastic bodies, moving terminals and static terminals assembled in the upper and lower plastic bodies, and clamping the upper and lower plastic bodies Integral metal case. For example, Patent No. 200980100028.X of the People's Republic of China discloses the most widely used coaxial switch technical solution in the prior art, which contacts the static terminal by setting a bifurcated structure at the contact end of the movable terminal and the static terminal. This technical solution can achieve various technical performances of ultra-micro-sized coaxial switches, but the part of the movable terminal that provides elastic force needs to be bent into an arched shape, and the bending structure will generate internal st...
