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 and a static terminal which are fixed in the terminal groove, 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; and the terminal groove comprises a concave part and a supporting wallformed at the rear end of the concave part; the moving terminal comprises a first holding part fixed at the front end of the terminal groove, a first welding pin extending from the first holding partto the lower surface of the insulating base, and an elastic arm formed by extending backwards from the first holding part; and the free end of the elastic arm is lapped above the support wall, and thestatic terminal comprises a second holding part fixed at the rear end of the terminal groove, a second weld leg extending from the second holding part to the lower surface of the insulating base, anda contact arm formed by extending from the second holding part. 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 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...
