  • Patent number: 6902439
    Abstract: A wire connect device includes a bulb seat having a body that has a screw shell and a plane formed opposite to the screw shell. A switch is mounted on the body and controls multiple electric elements in the body. Two connectors upwardly extend from the plane and are rectangular and parallel to each other for defining a groove. Two electrode plates extend into the groove and are electrically connected to the multiple electric elements. Each electrode plate has a sharpened free end allowing the electrode plates easily prick into the wire and electrically communicating with the cores in the wire. A fastener is mounted to the two connectors to hold the wire in place.

The miniature incandescent lamp is held in the plug-in base. The partition member is integrally formed with a bottom wall of the plug-in base. The right and left urging lugs are disposed on opposite sides of the partition member. The housing includes an upper end wall having an opening for passage of the plug-in base, a lower end wall having a slot adapted to receive two electric leads, and an inner intermediate circumferential wall communicating the upper and lower end walls. When the plug-in base, together with the miniature incandescent lamp, is inserted into the housing, lead-in wires of the miniature incandescent lamp and the electric leads will be firmly clamped between the intermediate circumferential wall and the right and left urging lugs to ensure good electrical contact and to prevent entrance of rainwater thereinto.

  • Patent number: 6347965
    Abstract: An electrical connection mechanism used in a miniature light bulb string mainly comprises a block or plug that can be inserted into the lower portion of a bulb holder shell. The block or plug is provided with a U-shaped conductor plate that presses against two opposite conductive terminals when it is seated in the shell to form an electrical connection between the terminals. Thus when one of the light bulbs is in malfunction, electrical current in the miniature light bulb string still can be maintained.

  • Patent number: 6343942
    Abstract: Electric wires 41 are housed within a housing space 36 and make contact with bulb-inking contacting members 22, all of the bulbs 42 being connected via bulb terminal fittings 19 and bulb-linking contacting members 22. A multiple-light lighting fixture can be made suitable for a varying number of bulbs or for bulbs of varying pitch merely by altering the length of the electric wires 41. As a result costs can be reduced compared to the case in which a bus bar is formed in a unified manner with terminal areas which make contact with bulbs, and in which a plurality of types of bus bars are produced in order to correspond to the number of bulbs or the pitch thereof.

  • Patent number: 6341881
    Abstract: A single-conductor positioning device on each or either lateral side of a bulb holder, wherein, a receiving seat is integrally formed on the side of the bulb holder and is comprised of two hook-like sidewalls opposite to each other and forming an inner slot and a central slit. The wall portions of the sidewalls on both sides of the central slit are further folded to form respectively hooks. A recessed surface is formed centrally on an inner wall of the inner slot. A plug with a base can be fitted in the receiving seat, and has vertical grooves for connecting with the hooks on the receiving seat. The plug has a clamping recess provided in opposition to the recessed surface to form together with the latter a conductor clamping-slot. Inserting of the plug into the receiving seat can firmly position the conductor at a central position on the lateral side of the bulb holder; engagement of the plug with the vertical grooves can prevent the central slit from pulling outwardly.

  • Publication number: 20010043471
    Abstract: The present invention provides a C.I.P. of U.S. patent application Ser. No. 09/546,175, namely, an improved device for the bulb socket. This refers to a jacket set at the caulking part above the fixture of the bulb socket. There are several jack catches inside the jacket. Besides, the outer part of the bulb is added with several convex catches. When the bulb is inserted into the fixture of the bulb socket, the convex catches of the bulb will be geared between the jack catches within the jacket. Such an engagement can fix the bulb with the fixture of the bulb socket more effectively.

  • Patent number: 6296529
    Abstract: A plastic covering 32 of an electric wire 30 is removed, exposing a core wire 31, this core wire 31 being attached to core wire receiving members 13 of a lamp body 10. Attaching a bulb socket 20 to the lamp body 10 causes the core wire to be resiliently held between contact members 24D of the bulb socket 20 and the core wire receiving members 13, thereby connecting the bulb socket 20 and the electric wire 30. The core wire 31 makes direct contact with the contact members 24D, and therefore connecting terminals are not required between the bulb socket 20 and the electric wire 30, the number of components is thus decreased.
