Lamp Or Electron Tube Socket Or Base Patents (Class 439/602)
  • Patent number: 4738630
    Abstract: A cover module (1) of an adaptor for single-based fluorescent lamps is prded with a cylindrical element, having a cross-sectionally rectangular recess (2) therein, for receiving the base of the lamp. Spring elements (5) for gripping the base are formed on opposing interior sidewalls of the recess (2). The lower ends (6) of the spring elements (5) are integrally formed with the cover module (1) and the play or travel of each of their upper ends (7) is limited by a stop (10) formed on the cover module (1). Between the upper (7) and lower (6) ends, detents (8) are formed on the spring elements (5) forcibly engage behind, in the direction of lamp insertion, cam surfaces (12) on the lamp base. The force, with which the lamp base is held in the cover module (1), is selectable within a certain range, dependent upon the spacing of the play-limiting stops (10), thus assuring a secure mechanical engagement of the lamp in the cover module socket.

    Abstract: An under hood and luggage compartment lamp assembly which is adapted to be positioned on a hood or luggage compartment of a vehicle. The lamp assembly comprises a plastic body which has, at one end, a first set of spaced terminals the outer ends of which extend parallel for connection to a plug of a wiring harness and at the other end of a second set of spaced terminals, the outer ends of which are shaped for receiving a wedge based lamp. The inner end of the other of the first set of terminals is bent and resiliently engages the spherical contact of a mercury switch and the inner end of one of the second set of terminals is bent and engages the button contact of the mercury switch. The inner end of the first set of terminals directly engages the inner end of the other of the second set of terminals. The body is provided with projections and recesses for locating the terminals such that they can be dropped in place during assembly. A cover closes the body and mechanically locked to the body.
