Improved structure of electric connector

The utility model relates to an improved structure of an electric connector. An electrical module of the electric connector is characterized in that a plurality of terminals are integrally formed in each of two insulating base bodies, a butting side and a welding side on two sides of each terminal respectively extend out of the external parts on both sides of the two insulating base bodies, the opposite inner side surfaces of the two insulating base bodies are provided with a plurality of convex buckles and concave holes which are arranged in complementary manner, the convex buckles and concave holes can be relatively embedded with one another to clamp a grounding piece, and clamping grooves are formed in two outer side edges of the two insulating base bodies so that buckling parts on one sides of two buckling members to buckle and clamp, clamping sides on the other sides of the two buckling members respectively extend to two opposite outer sides of the plurality of terminals, and a shielding shell body can cover the two insulating base bodies. According to the improved structure of the electric connector, the insulating base bodies of a single type are manufactured through a single mould, the two insulating base bodies can be assembled in a relative complementary mode, thereby achieving the purpose of reducing manufacturing cost of the electric connector.
