Wire spring plug bush

Abstract

The invention relates to a wire spring plug bush comprising an outer sleeve, a clamping ring and a wire spring, wherein an insertion hole is formed in the outer sleeve, the insertion hole is formed into a stepped hole structure comprising a first insertion hole section and a second insertion hole section, the hole diameter of the first insertion hole section is more than that of the second insertion hole section, the first end of the first insertion hole section communicates with external environment, the second end of the first insertion hole section is connected with the first end of the second insertion hole section, and a first annular step surface is formed at the part where the second end of the first insertion hole section is connected with the first end of the second insertion holesection; the clamping ring is installed on the first annular step surface; the first end of the wire spring is inserted into the second insertion hole section after penetrating through the clamping ring from the first insertion hole section, and a plurality of claws are arranged on the second end of the wire spring, and fastened between the inner wall of the first insertion hole and the outer ring surface of the clamping ring by the way of bending from the inner ring surface of the clamping ring to the outer ring surface of the clamping ring. The wire spring plug bush has the advantages of being high in conductive efficiency, strong in reliability, simple to process, prone to manufacturing, low in processing cost and high in installation efficiency.

Description

technical field [0001] The invention relates to the technical field of conductive connectors, in particular to a wire spring socket. Background technique [0002] The connector is an important device for conducting electric current. In modern industry, especially in electrical appliances, connectors are widely used. As an important part of the connector, the metal terminal has high requirements for its manufacturing and processing, and strives to be economical and simple to control the cost. [0003] At present, most metal terminals use a combination of wire spring sockets and pins. The existing structures of wire spring sockets mainly have the following two forms: [0004] 1. The wire spring socket includes a sleeve body, a sleeve cap and a plurality of wire springs, and the sleeve body has a jack. Insert a plurality of wire springs into the socket, the wire springs are closely arranged along the edge of the sleeve body, and the part protruding from the socket is bent to...

AI Technical Summary

Problems solved by technology

[0006] Among them, in the first structural form, the sleeve cap is sleeved on the outside of the sleeve body, and the two need to be fixed by means of pressure deformation or welding, which is difficult to operate, low in efficiency, and difficult to control; the second structural form Among them, the processing of the annular groove relies on milling, and the difficulty of processing further leads to the problems of low production and assembly efficiency and high production costs
