Conductive shrapnel and coaxial connector using the shrapnel

Abstract

The invention discloses a conductive shrapnel and a coaxial connector using the shrapnel. The shrapnel is a stretchable helical structure spirally formed by a metal sheet and used for conducting electricity, and has a helical shape with one end small and the other end large. The coaxial connector includes: a metal sheet spirally formed and elastically stretchable and conductive shrapnel, which is in the shape of a spiral with a small end and a large end, and a closed and stretchable shielding space is formed in the shrapnel; an insulator, which is fixed Installed in the shielding space of the shrapnel; the central elastic thimble assembly is installed in the center of the insulator, and the upper and lower ends of the central elastic thimble assembly protrude from the upper end surface and the lower end surface of the insulator. The conductive shrapnel of the present invention has a simple structure, good elastic capacity and strength, and a large elastic force value. Even under overvoltage and long-life working conditions, there will be no fatigue damage or even fracture, so that it has an extremely long service life. , to ensure the stability and quality of docking, and has strong market competitiveness.

Description

Technical field: [0001] The invention relates to the technical field of connectors, in particular to a conductive elastic sheet and a coaxial connector using the elastic sheet. Background technique: [0002] The main supporting fields of connectors are transportation, communication, network, IT, medical care, home appliances, etc. The rapid development of product technology level in the supporting fields and the rapid growth of the market are strongly driving the development of connector technology. So far, the connector has developed into a serialized and specialized product with a complete range of products, rich varieties and specifications, various types of structures, subdivisions of professional directions, obvious industry characteristics, and standard system specifications. [0003] The electrical contact shrapnel used in the connector is mostly formed by bending metal sheets. The bending part is formed with a certain arc, and is restored by the elasticity of the ben...

AI Technical Summary

Problems solved by technology

[0003] The electrical contact shrapnel used in the connector is mostly bent and formed by metal sheet, and the bending part is formed into a certain arc, and the elasticity of the bending part is restored to keep the shrapnel with a certain reaction force (elastic force). The elasticity of this shrapnel Relying on the elastic recovery of a bending part, but the elastic value is too small, and it is easy to be fatigued, damaged, or even broken during overpressure and long-life work, causing great trouble to users.
