Abstract
Abstract A cable end receptacle connector includes a metal shell receiving a nonconductive body therein. The body has a cavity defined in a rear face thereof and a plurality of channels defined in a front face thereof in communication with the cavity. Each channel receives and retains a contact terminal therein. A cover member is fixed to the rear face of the body and substantially blocks the cavity. The cover member has a plurality of slots defined between spaced wall segments for receiving reduced sections of the corresponding contact terminals therein thereby securely retaining the contact terminals and effectively resisting an external load applied thereto. The cover member has a rear projection defining a plurality of spaced grooves therein for receiving and containing tail sections of the corresponding contact terminals. The tail sections are soldered to wires and the grooves confine excess molten soldering material that attaches the wires to the contact terminals. Thus, the soldering material is prevented from electrically connecting adjacent contact terminals.
