Abstract

Abstract A swivel connector for mechanically and electrically joining an electric cord to an electrical appliance. First and second connector body sections are axially aligned. A first body section has a plastic casing with an outwardly extending elongated axially aligned prong carrying plural contacts axially spaced from each other. The casing defines a swivel bearing boss coaxial with the prong. The second body section has a contact mounting block and a plastic casing surrounding the block and interlocking with the first casing. The mounting block defines a swivel bearing recess mating with the swivel bearing boss and has an elongated prong receiving recess axially aligned with the swivel bearing recess and boss. A first and second means are provided on the first and second body sections for stopping axial movement of the prong while permitting swiveling movement thereof. A full 360° swivel connection results in a self-contained efficient connector.
