Socket electric connector and combination thereof with plug electric connector

The utility model relates to an electric socket connector and a combination of the electric socket connector and an electric plug connector. The electric socket connector comprises an insulated body, a plurality of first conductive terminals, a plurality of second conductive terminals and a metal shell; wherein, the insulated body comprises a base, a first tongue piece and a second tongue piece; the first and the second tongue pieces are spaced from each other and transversely extended forward from the base; the first conductive terminals are assembled on the first tongue piece and used to transmit electric signals meeting the first specification; the second conductive terminals are assembled on the second tongue piece and used to transmit electric signals meeting the second specification; the metal shell wraps the insulated body and defines a plugging space along with the base and the first and the second tongue pieces; and the metal shell defines a plugging port through which the plugging space is communicated with the outside. Consequently, the dimension designs of the two tongue pieces can be different, so that the arrangement positions and number arrangement of the conductive terminals on the two tongue pieces can be flexible.
