Abstract: An electrical connector, comprises a dielectric housing defining front, rear, top, bottom and side walls. The front wall defines a receiving chamber therein. An insert detachably is assembled to the rear wall of the housing. The insert carries terminals each having a connecting arm extending into the receiving chamber. A pair of wedges is formed on the side walls whereby the housing is snugly disposed in a recess defined in a printed circuit board. An EMI shield is assembled to the housing. The EMI shield defines a pair of slots having its sides snugly received in retaining grooves defined in the wedges.
