Abstract: A lampholder for receiving one end of a fluorescent lamp and the associated pair of electrical contact pins is disclosed. The lampholder has a base member with slots for receiving the fluorescent lamp pins and a contact or terminal carrying plunger is disposed within the base member so as to be unilaterally movable between an extended position and a retracted position. The base member includes a pair of lead wire accepting openings remote from the pin receiving slots and the electrical contacts each include a lead wire accepting aperture. The apertures are in alignment with the openings only when the plunger is in the extended position. The lead wires fit snugly in the openings so that any subsequent flexing of the a lead wire occurs away from the region of contact between the wire and its corresponding terminal. When a lead wire is passed through an opening and corresponding aperture and the plunger is moved from the extended to the retracted position, the wire is deformed and securely gripped.

Abstract: A method of insulating electrical connectors having terminals with leads extending therefrom by using a flexible insert arrangement for an electrical connector mold for supporting leads extending therefrom and closing the mold end which includes a flat resilient body having one or more lead-accepting depressions normal to the body across one edge thereof and an arrangement actuable as the mold halves are closed on one another for deforming the body to temporarily displace the body resilient material about each electrical lead extending from the mold to complete the formation of an insulating material-accepting connector forming cavity. A flowable insulating material is then injected into the cavity to form the insulated connector.
