  • Patent number: 8808023
    Abstract: An electrical appliance for a lampholder socket having a socket axis of rotation has a housing rotatable by an application of an applied torque thereto. A screw base is configured to be inserted in the lampholder socket and threadedly connected to the lampholder socket upon a rotation of the screw base in a first direction about the socket axis of rotation. A torque limiter is fixedly attached to the screw base for rotation therewith. The torque limiter couples the housing to the screw base for rotation therewith when the applied torque is less than a predetermined magnitude and couples the housing to the screw base for rotation relative thereto when the applied torque is greater than the predetermined magnitude. An electrical device is mounted in the housing and electrically connected to the screw base.

  • Patent number: 6257740
    Abstract: A lamp having a light bulb connected to a base insertable into a light socket in such a way that insertion breaks an electrical circuit between two spring terminals inside the socket and reestablishes it through the lead wires on the light bulb. The light bulb has a filament and two lean wires connected to the filaments. The filaments extend from the bottom of the base and are bent outwardly and upwardly around the base. The bulb with its base are insertable into the light socket. Wires from a source of electricity enter the socket and form electrical terminals, one on either side of the socket. Two spring terminals within the socket are biased toward each other and will conduct when supplied with an electrical potential unless separated. A protrusion on the base of the light bulb separates the spring terminals. Thus, in a light string where the lights are electrically in series, removal of a light bulb of the present invention will not cause the string to go out.

The assembly has a housing made of a dielectric material, having a central contact and having an outer contact. A rotatable sleeve made of a dielectric material is situated in the housing. The sleeve can be rotated by means of at least one lug fitted on the outer periphery of the base of the gas discharge lamp. A tongue which moves from a first position to a second position when the gas discharge lamp is screwed in is fitted on the rotatable sleeve. The tongue opens or closes an electrical circuit, or actuates a switch.

  • Patent number: 5518425
    Abstract: A socket assembly which includes a socket, an annular positioner and two leaf conductors. The socket includes two slots defined in a bottom and a groove defined in an internal surface. The annular positioner includes an opening defined therein and a ridge formed on an external surface. The ridge is received in the groove when the annular positioner is received in the socket to restrain rotation of the annular positioner with respect to the socket. The leaf conductors are inserted through the slots. One of the leaf conductors includes an upper tip inserted through the opening to be retained between the socket and the annular positioner to prevent bending thereof and engagement between the leaf conductors when a bulb is received in the socket.

  • Patent number: 5008588
    Abstract: A wedge-type lamp bulb assembly consists of a bulb containing a filament and a wedge-shaped base extending from the bulb. Several lead wires connected to the filament are led out from the bottom of the wedge-shaped base, and folded along the front and rear sides of the wedge-shaped base. There are provided inside the socket in which the wedge-shaped base is removably held a plurality of terminals which are in resilient contact with the lead wires, and a pair of guide protrusions is formed on the inner walls of the socket along the inserting direction of the wedge-type lamp bulb. There is formed on the front and rear sides of the wedge-shaped base in positions corresponding to the pair of guide protrusions a pair of protrusions defining guide ways through which the guide protrusions are passed. Thus, the wedge-type bulb can be easily assembled into the socket and also securely held therein.

  • Patent number: 4888519
    Abstract: The electric lamp has a lamp vessel (1) having an end portion (3) which is fixed inthe lamp cap (5) by means of polyethersulphone (8) as a thermoplastic synthetic resin, which has adhered both to the lamp vessel and to the lamp cap. The end portion (3) has non-circular cross-sections where it is in contact with the synthetic resin (8) due to projections (10) projecting into the synthetic resin (8). A current supply wire (11) can be clamped between the synthetic resin (8) and the sheath portion (6) of the lamp cap (5) in order to establish electrical contact therewith. The lamp can be assembled by arranging in the hot state of the end portion (3) a polyethersulphone ring (8) around this end portion (3) and by providing the lamp cap (5) in the hot state around the polyethersulphone ring (8).

  • Patent number: 4742434
    Abstract: A vehicular lamp in which the back cover is positively prevented from coming off the main body of the lamp and connectors of the lamp can be easily connected and disconnected. The lamp includes light bulb, a lamp body, and a back cover detachably engageable with the body. The back cover secures a first connector. A second connector is provided which is adapted to be connected with the first connector, and the lamp body is formed with a stop engageable with the second connector. The first and second connectors are positioned on the same side of the back cover when they are connected. When the connectors are coupled together, the side surface of one of the connectors is in surface contact with the surface of the lamp body so that angular displacement of the back cover relative to the lamp body is prevented by this surface contact, in addition to the interlocking of the connectors.
