Problems solved by technology

[0005] Because the pins are passively connected in the contact pair, the purpose of connection is mainly achieved by the radial force exerted by the socket in one direction. However, no matter what the structure of the socket is, the actual contact surface is small. After pulling out, the reliability is reduced due to mechanical wear or poor elasticity, and there is a risk of connection failure

Abstract

The invention provides a method for the axial elastic force application connection of electrical connector contact pairs. The method adopts an elastic element to apply axial external force to a contact pair consisting of a contact piece A (1) and a contact piece B (2), so as to combine the two tightly, thereby forming the electric connection with lower conductive resistance. One end of the elastic element is in contact with an insulating base so as to turn into a relative fixed end; and the other end of the elastic element directly acts on a preset fixed end face of an electric conductor contact piece, and is a relative displacement end during axial force application. The contact pair is independently formed by the end planes of the two contact pieces with simple structure. As axial elastic connection can not be affected by shock or other external factors, the connection reliability is higher. The contact pair can be formed by a positive contact piece and a negative contact piece as well, which ensures that the radial and axial directions of the contact pair are uniform in stress and contact.
