Abstract

A metal leaf spring protection structure of electrical connection terminal includes a main body having 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 second section. The locating section has a head section and a tail section. The tail section extends to a position of the bight section to form a hook-like structure for providing an elastic action force and a support system. The locating section is positioned in the reciprocally moving path of the second section to set up a moving end point of the second section to improve the shortcomings of the conventional metal leaf spring that when plugging in the conductive wire, the metal leaf spring is over-bent to affect the pressing and securing effect.
