Conductive contact

Abstract

The invention provides a conductive contact which comprises a contact body. The contact body is provided with a conductive butt-joint surface, the conductive butt-joint surface is provided with annular installation grooves whose axes are vertical to the conductive butt-joint surface, each annular installation groove includes a notch, a conductive spring coil is mounted in the notch in the axial direction, the diameter of the notch is greater than the internal diameter of the conductive spring coil in the natural state, the groove wall, closes to the axis, of the annular installation groove serves as the inner-side groove wall, and the diameter, at the notch, of the inner-side groove wall is greater than that at the groove bottom. The conductive contact cannot be mounted in the installation groove unless the conductive spring coils are expanded in the radial direction, each conductive spring coil is contracted in the radial direction after being mounted in the installation groove, is blocked in the installation groove by the surface, at the notch position, of the inner-side groove wall, and is prevented from axial movement in the installation groove or disengagement from the installation groove, installation is convenient, and the conductive connection process is very stable and reliable.

Description

technical field [0001] The invention relates to a conductive element, in particular to a conductive contact. Background technique [0002] The existing connector socket contact forms mainly include opening hole, wire spring hole, crown belt hole and crown spring hole, etc., but no matter what type of socket is in contact with the pin, it relies on radial elastic pressure to achieve insertion. The pins and sockets are in direct and reliable contact. To ensure reliable contact of the pinhole, a certain contact length in the axial direction is required, which increases the axial dimension of the connector and greatly limits its applicable occasions. [0003] The Chinese utility model patent with the authorized announcement number CN203521699U and the authorized announcement date of April 2, 2014 discloses an electrical connection structure that can reduce contact resistance. There is a mounting groove on the axial end surface of the base, and a canted coil spring that can pro...

AI Technical Summary

Problems solved by technology

However, the installation groove for installing the canted coil spring on this conductive contact is a circular U-shaped groove, and the canted coil spring is easy to move axially in the U-shaped groove, which affects the stability of the conductive connection. When the base is separated, the canted coil spring can easily slip out of the opening of the installation groove, which affects the normal conductive connection, and the reliability and safety of use are poor
