Abstract
The invention discloses an electric connector which comprises an insulating body and a terminal module fixed on the insulating body. The insulating body is provided with a front end face, a butt joint space and a plurality of terminal accommodating grooves. The butt joint space backwardly recesses from the front end face. The terminal accommodating grooves backwardly recess from the butt joint space and penetrate the insulating body. The terminal module comprises a substrate and conductive terminal fixed on the substrate. Each conductive terminal is provided with a welding part and an elastic contact part, wherein the elastic contact part bends upwardly from the front end of the welding part and extends into the butt joint space. The tail end of the elastic contact part bends towards the substrate to form a retaining part which can be butted against the substrate. When unmatched other electric connectors are inserted, the retaining parts of the conductive terminals can stop circuit boards to prevent the conductive terminals from entering adjacent or similar terminal accommodating grooves from corresponding accommodating grooves.
