An electrical connector includes a unitary base elongated along a longitudinal direction. A first tongue extends forwardly from the base and has a uniform thickness along the longitudinal direction. The first tongue comprises a plurality of spaced apart first contacts. A second tongue extends forwardly from the base and comprises a plurality of spaced apart second contacts. The first and second tongues define a gap therebetween that extends from a front edge of one of the first and second tongues toward the unitary base.
