Cylindrical elastic component and coaxial connector

Abstract

The invention discloses a cylindrical elastic component and a coaxial connector. The cylindrical elastic component is provided with a plurality of hollow holes penetrating through an inner cavity along the outer side surface of the cylindrical elastic component inwards, and multiple layers of elastic structures are formed among the hollow holes. The cylindrical elastic component can be telescopically deformed in an axial direction through the multiple layers of elastic structures. The coaxial connector comprises the cylindrical elastic component. A plurality of hollow holes penetrating throughthe inner cavity are formed along the outer side surface of the cylindrical elastic component inwards. multiple layers of elastic structures are formed among the hollow holes, and the cylindrical elastic component can be telescopically deformed in the axial direction through the multiple layers of elastic structures. The coaxial connector further comprises an insulator which is fixedly installedin the cylindrical elastic component, a central elastic ejector pin assembly which is arranged at the center of the insulator and coaxial with the cylindrical elastic component. The upper end and thelower end of the central elastic ejector pin assembly extend out of the upper end surface and the lower end surface of the insulator. The upper end of the cylindrical elastic component and the upperend of the central elastic ejector pin assembly are in multidirectional tolerance elastic contact with a PCB.

Description

Technical field: [0001] The invention relates to the technical field of connectors, in particular to a cylindrical elastic member and a coaxial connector. Background technique: [0002] The main supporting fields of connectors include transportation, communication, network, IT, medical care, home appliances, etc. The rapid development of product technology level in supporting fields and the rapid growth of the market have strongly driven the development of connector technology.

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.
