ABSTRACT:
A socket (5) for a double-ended lamp (12) comprises a pair of opposed connectors (10) including single-piece ceramic housings (14) each having a top surface (16) and a bottom surface (18) and including a contact receiving area (20) formed in the top surface (16). An electrical contact (22) is positioned in the contact receiving area (20) and secured by any suitable means. The electrical contact (22) has a rectangular base (24) with two sides (26, 28) and two ends (30, 32). Opposed, upright walls (34, 36) extend from the sides (26, 28) of the base (24), and an upright clip (38) extends from one end of the base, for example, end (30). The upright walls (34, 36) and the upright clip (38) have portions projecting beyond the top surface (16) of the ceramic housing (14) to receive an end (40) of the lamp (12) therein. The electrical contact (22) is further mounted within a supplemental spring (50) having opposed legs (54, 56) which are adjacent to the upright walls (34, 36) of the contact. The legs (54, 56) engage the upright walls (34, 36), particularly when a lamp is inserted, providing increased tension thereto. The opposed connectors (10) are separated by a given distance and attached to a connecting bar (70).
