Spiral jack connection piece

Abstract

The invention discloses a spiral jack connection piece, and relates to the technical field of connection pieces. The spiral jack connection piece comprises a metal thin wall sleeve and an outer sleeve, wherein the metal thin wall sleeve is arranged in the outer sleeve and is a metal cylinder body which is integrally formed, the metal thin wall sleeve comprises a front end head, a rear end head anda plurality gate strips, the plurality of gate strips are connected to the front end head and the rear end head in an inclination way, the plurality of gate strips are uniformly distributed around acentral axis of the cylinder body, a penetrating strip-shaped hole is reserved between adjacent gate strips, penetrating Z-shaped guide gaps are formed in the front end head and the rear end head, oneend of the guide gap of the front end head and one end of the guide gap of the rear end head communicate with two ends of one of the strip-shaped holes, and the other end of the guide gap of the front end head and the other end of the guide gap of the rear end head extend along an axial direction of the metal thin wall sleeve so as to achieve partitioning of the front end head and the rear end head. The spiral jack connection piece has the beneficial effects that a high surface and a low surface at two ends are prevented during a twisting process, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of connectors, and more specifically, the invention relates to a screw-type socket connector. Background technique [0002] The jacks of the existing electrical connector contacts mainly adopt spring or reed structures, among which the more typical structures are crown spring jacks with the waist of the springs, and jacks with twisted stamped springs and press-fitting at both ends. [0003] The current crown spring jack is stamped and divided into a fence shape consisting of several metal strips connected at both ends and perpendicular to the end surface, and then coiled and the middle part is waisted to make each metal strip bend in the middle. Shrink towards the axis, forming a structure with two large ends and a small middle. The crown spring socket of this structure is in contact with the surface of the contact pin at the waist of the elastic metal strip. Because of the structural limitation, it cannot ...

AI Technical Summary

Problems solved by technology

However, when the electrical connector contacts in the prior art are twisted, high and low surfaces appear on the electrical connector contacts, the defect rate of the electrical connector contacts is high, and production resources are wasted
