A cable end connector includes an insulative body, a number of terminals received in the insulative body, a spacer mounted behind the insulative body, and an insulative housing molded to enclose the inuslative body and the spacer. The spacer includes an intermediate chamfer at a mounting end thereof to prevent interference during mounting of the spacer to the insulative body. A stopping wall is disposed at two opposite sides of the chamfer to prevent molten plastics from flowing into the insulative body during molding the insulative housing.
