Abstract

A shift member fixing structure of electrical connection terminal includes an assembly of a terminal and a shift member to improve the shortcoming of the conventional terminal that the structure is complicated and the manufacturing cost is higher. The terminal includes a main body defining a chamber and a metal leaf spring disposed in the chamber for pressing a conductive wire or releasing the conductive wire in response to the operation of the shift member. A predetermined section of the shift member is formed with an insertion section and walls defining the insertion section. A part of the wall is removed to provide elastic effect for the insertion section. The removed part is repositioned on a surface of upper section of the main body to form an interference section. After the shift member is pressed down, the interference section is assembled with the insertion section.

First claim
