Abstract

A metal leaf spring structure of electrical connection terminal includes a main body. The main body has a base section defined with a first end and a second end. The first end is connected with a first section and a locating section. The second end is connected with a bight section and a reciprocally movable second section. The locating section has a head section and a tail section. The locating section is positioned in the reciprocally moving path of the second section to setup a moving endpoint of the second section. The metal leaf spring structure of electrical connection terminal improves the shortcomings of the conventional metal leaf spring that the conductive wire cannot be plugged into the terminal by a precise angle so that the metal leaf spring is over-bent to affect the pressing and securing effect.
