Abstract

The utility model relates to an electric connector. The inside of an insulating seat body is provided with a plurality of penetrating channels capable of containing a conducting terminal, an abutting terminal and an elastic component; one side of the penetrating channels is provided with a through hole; one side of the base of the conducting terminal extends outwards to form a contact part positioned at the through hole, the other side far from the contact part forms a sleeve joint hole into which the elastic component can be inserted; both sides of the base of the abutting terminal extend in the same direction to respectively form a side wall; and the inner sides of the two side walls towards the base extend to form an elastic arm capable of abutting against the conducting terminal. When the conducting terminal is subjected to an ejection action of external force, the conducting terminal is pushed to abut against the elastic component to form an elastic compression deformation, so that the conducting terminal can not easily deviate or swing when making a stretching/retracting displacement in the abutting space between the two side walls of the abutting terminal, thereby ensuring the stability of the integral structure and enhancing the stability of the electric contact.
