Abstract

Abstract A lamp assembly including a connector enabling mounting of the lamp assembly in an aperture in a wall by insertion from either side without the use of tools. The connector defines a cavity for receiving the lamp, and is tapered in both directions from a transverse annular mounting groove. The connector is also split or slotted longitudinally to enable radial compression during insertion into an aperture. Lamp leads are mechanically and electrically connected to connecting pins or to insulated wires by being press-fitted in crimped splices which are interference-fitted into portions of the connector cavity.
