Socket electric connector and manufacture method thereof

Provided is a socket electric connector that comprises conductive terminals, a metallic housing, and an insulated body. The insulated body is formed by injection molding with the conductive terminals and the metallic housing and comprises a tongue plate. When the electric connector is formed by injection molding, one die for positioning the conductive terminals is disposed on the rear ends of the conductive terminals. Thus, no structure, such as a gap or a recess, capable of influencing the intensity of the tongue plate is arranged on a joint of the root of a formed tongue plate and the rear end portion of the insulated body. Therefore, the intensity of the tongue plate is guaranteed and the waterproof performance of the root of the tongue plate of the socket electric connector is improved.
