A connector has a dielectric housing having a base. The base has a protruding platform at a front surface thereof. A peripheral dimension of the protruding platform is smaller than that of the base. At least one connecting unit is mounted to the dielectric housing with contacts thereof extending out from both a front surface of the protruding platform and a rear surface of the base. A plastic shield is integrally molded with the dielectric housing and encloses a periphery of the dielectric housing. The plastic shield has a basic body. The basic body has a first cavity at a front thereof for receiving the protruding platform and a second cavity disposed inside the basic body and communicating with the first cavity for accommodating the base.
