  • Publication number: 20120199373
    Abstract: An electrical connection box includes an insulating plate made of resin that supports an input load applied on a connection terminal to be connected to an electrical part. The insulating plate is contained between upper and lower cases and provided with a honeycomb structure portion penetrating through the insulating plate in a plate thickness direction. It thus becomes possible to provide an electrical connection box of a novel structure provided with an insulating plate not only ensuring strength with a smaller amount of resin but also capable of enhancing heat dissipation.

  • Patent number: 6860643
    Abstract: An optical connector is constituted of a connector housing, a shielding case, and optical elements. The shielding case is split into a case main body section and a heatsink mechanism section, both joined together to constitute housing recesses. While the case main body section and the heatsink mechanism section are joined together, element main body sections are held between them. A non-joint plane of the heatsink mechanism section is housed in a case housing recess of the connector housing in an outwardly exposed state. A corrugated heatsink fin section is formed in the non-joint plane. The housing recesses into which the element main body sections are to be housed are partitioned from each other.

  • Patent number: 6659792
    Abstract: An electric connection box includes a cover fitted on a lower side of a body having mounting portions, and the cover is fixedly secured to a vehicle body. A wire harness is extended outwardly from a portion of the body, disposed near to one corner portion thereof, through an escape groove. Plural lock mechanisms, in which a lock piece portion can be elastically fitted into a lock groove, are provided at fitting peripheral surfaces of the body and cover, and are disposed near to four corner portions thereof respectively. One lock mechanism, disposed near to a position where the wire harness is extended outwardly, has a semi-lock structure, and thus has a smaller retaining force than the other lock mechanisms.

  • Patent number: 4957455
    Abstract: A connector socket for a wedge-base lamp is improved by socket structures which aid in leading the base end of the bulb into alignment with the insertion channel and at the same time prevent contact between the base end and the top ends of the socket terminals in a way which might lead to wrenching or deformation of the terminals.
