  • 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.

  • Publication number: 20010043768
    Abstract: The present invention provides a bearing assembly (10) with a locking collar (27) and provides a singular means for locking a bearing assembly onto a rotatable shaft (41). The bearing assembly (10) made in accordance with the principles of the present invention includes an outer bearing race member (18) and an inner bearing race member (12). The inner bearing member (12) has an inside diameter and an axial extension (25). A locking collar (27) is provided having a larger inside diameter (32) and a smaller inside diameter (34). A gap (35) is positioned circumferentially in the locking collar (27), the gap defining opposed separated planes (26, 28) cutting approximately radially through the locking collar. The locking collar (27) can be slidably fitted over the axial extension (25) with the smaller inside diameter (34) of the locking collar positioned at the furthest extent of the axial extension (25). A fastener (46) is provided for compressing the gap (23).

  • Patent number: 6217387
    Abstract: A high strength terminal fitting 30 for a wedge-base bulb is provided which is not likely to be deformed while being assembled into a bulb socket. The terminal fitting 30 is provided with a pair of holding pieces 35, and a tab 31 formed by bending a portion of one holding piece 35R to have a steplike shape is provided with a tab side portion 38 extending toward the other holding piece 35L. A first small projection 39A of a receiving portion 39 formed by bending the other holding piece 35L1 is placed on the upper surface of the tab side portion 38. Even if the tab side portion 38 continuous with the tab 31 tries to undergo an upward displacement upon being subjected to an insertion resistance which acts during the insertion of the tab 31 into a tab mount hole 25 formed in a bulb socket 20, the first small projection 39A of the receiving porion 39 restricts the upward displacement of the tab side portion 38, thereby preventing the deformation thereof.

  • Patent number: 5980328
    Abstract: A connector assembly for attachment to a substrate wherein an engagement element is on one of the housing and the terminal and a stabilizer, complementary thereto, is on the other, thereby restraining the terminal from movement in any direction perpendicular to the insertion direction. Alternatively, a restriction piece is attached to--or part of--the housing so that it retains the attachment end of the terminal within the housing until it is ready to be attached to the substrate. In this way, the opportunities for damage or distortion of the terminal are minimized.

  • Patent number: 5709565
    Abstract: A press-connecting terminal is blanked from a pre-plated electrically-conductive metal sheet by a press. A press-connecting groove, formed in this terminal, has a sharp edge portion at an inlet portion thereof. Blanked, sharp edges of the sharp edge portion cut a sheath of a wire. A contact conductive portion is provided below the sharp edge portion. Bent or folded edges of the contact conductive portion contact a conductor of the wire. A plated film is not separated from these folded edge portions, and therefore the contact resistance of these folded edge portions relative to the wire is low.

  • Patent number: 5577937
    Abstract: Connection portions are connected to leads of a capacitor. In this condition, when connection terminals are press-fitted in terminal receiving holes, the capacitor is received in an equipment chamber. A filler is filled in the part chamber, and is solidified, thus completing the assembly. In one alternative, an electronic part, soldered to a printed board, is received within a housing. Each of female metal terminals has an abutment piece, and the abutment piece is abutted against an associated printed line on the printed board in facing relation thereto. In another alternative, the connector housing is divided into two sections, that is, a housing member and a lid, so that the terminal receiving chambers, as well as the electronic part-receiving chamber, is openable. Press-contact terminals 309 are fixedly mounted on and project from a bottom of the electronic part-receiving chamber.
