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 comprises an insulating base provided with at least one terminal groove, a moving terminal, a static terminal, an insulating upper cover covering the insulating base, and a metal shell for fixedly holding the insulating base and the insulating upper cover into a whole, wherein the moving terminal and the static terminal which are fixed in the terminal grooves; each terminal groovecomprises an arc-shaped bottom wall and a forming wall which is formed at the rear end of the terminal groove and is provided with the static terminal; and the moving terminal comprises elastic armserected at the two ends of the arc-shaped bottom wall, welding parts formed by bending the front ends of the elastic arms, and contact parts which are formed by bending the rear ends of the elastic arms and can be in contact with the static terminal. And when the elastic arm is extruded and deformed towards the arc-shaped bottom wall, the contact parts move to be disconnected from the static terminal. The elastic force of the moving terminal of the coaxial switch 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 to test antenna signals. They generally include upper and lower plastic bodies, moving and static terminals assembled in the upper and lower plastic bodies, and clamping the upper and lower plastic bodies. As a one-piece metal shell. 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 providing a bifurcation structure at the contact end of the movable terminal and the static terminal. This technical solution can achieve various technical performances of the ultra-micro size coaxial switch, but the part that provides the elastic force of the movable terminal needs to be bent into an arch shape, and the bending structure will generate internal stre...
