Abstract: An electrical connector configured to mate with a mating connector along a mating direction includes an electrically insulative unitary housing, pluralities of top and bottom contacts, and an electrically conductive unitary shield. The pluralities of top and bottom contacts are disposed in a central slot at a respective top surface and a bottom surface of the central slot for making contact with corresponding conductive terminals of a tongue of the mating connector. The shield is removably assembled to the housing along the mating direction from a rear side of the housing. The shield includes a base shield substantially covering an entire bottom surface of a bottom wall of the housing, and opposing side shields substantially covering opposing side walls of the housing. The shield leaves substantially an entire top surface of a top wall of the housing and the rear side of the housing exposed.
