  • Patent number: 9553242
    Abstract: A semiconductor device package assembly which increases production efficiency of semiconductor devices by enabling the number of semiconductor device packages held by a carrier to be increased. A predetermined area of a first housing molded of white-colored resin, which holds a plurality of bent contacts, is covered by a second housing molded of black-colored resin, and a plurality of second housings are supported by a secondary molding carrier in high density. A linking portion of each contact and one or both of the first and second housings are integrated by insert molding.

  • Patent number: 8482680
    Abstract: In a power board, relay terminals penetrate a circuit board through fitting holes, and are connected to output terminals. The fitting holes are thus formed as through holes on the circuit board, and thereby on-board connectors provided for connection to the relay terminals on a chassis can be arranged on the back surface of the circuit board on the opposite side of the chassis. Electronic components free from restriction of the positional relationship with the chassis can be mounted on the back surface of the circuit board, as are the on-board connectors.

  • Patent number: 8319901
    Abstract: Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration. When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted.

  • Patent number: 7954968
    Abstract: In a backlight module, when relay connectors exposed to a back side of a chassis are engaged with the connector portions of a lighting jig, the power from the power supply source of the lighting jig is supplied to discharge tubes via the connector portions and the relay connectors. Thereby, the discharge tubes can be lighted, even if a power board is not connected to the relay connectors. At the time, the lighting jig is arranged to face the back surface of the chassis, and therefore optical sheets can be mounted to the chassis from the front side.

  • Patent number: 7905733
    Abstract: A power board includes an on-board connector having an output terminal that is surrounded by a housing made of synthetic resin. The output terminal is arranged in an area of the housing that is farther from the edge portion of a circuit board so that sectional arrangement is provided. The output terminal is thus surrounded by the synthetic-resin housing, and thereby a leak at the output terminal can be prevented. Further, the output terminal is arranged in the limited area of the housing farther from the edge portion of the circuit board, resulting in a long distance maintained between the output terminal and the edge portion of the circuit board, which can effectively prevent the leak.

  • Patent number: 7901101
    Abstract: Relay connectors are arranged to supply power from power boards arranged on the back side of a chassis having a substantially plate-shaped configuration to discharge tubes arranged on the front side of the chassis. Each relay connector includes a holder having an insulation property and to be mounted to the chassis, and further includes a relay terminal mounted to the holder and capable of electrical connection to the discharge tube and the power board. The relay terminal is immune to direct contact with the chassis. This enables the use of a metallic chassis.
