Abstract

An electric connector comprises an insulator body and a conductive terminal, wherein the insulator body is provided with a holding cavity and a front end surface; and the conductive terminal comprises a contact part arranged in the holding cavity. The holding cavity comprises a main body cavity and a side cavity extending towards a side direction from the main body cavity, wherein the main body cavity forwards penetrates the front end surface to form a plug-type port, while the side cavity does not penetrate the front end surface. In the electric connector, the side cavity prevents a butting element from falling off the holding cavity.
