Abstract: The present disclosure relates to an improved structure of an electric connector. Each of terminals has a butt joint part and is vertically linked with a joint part, and each joint part has an arch-shaped necked-down section with two grooves , and other side of joint part is linked with a positioning section which has an accommodating cavity and a protruding body separately formed at two opposite side surfaces thereof and is linked with an extension arm by other side. The extension arm is linked with an insertion section in a vertical direction. The insulative base member is formed integrally to encapsulate terminals, butt joint parts can be suspended and extended in a docking chamber, and extension arms and soldering parts are respectively exposed out of the insulative base member, so the terminals can be tightly fastened in insulative base member and the endurability of the electric connector can be enhanced.
