  • Patent number: 9024183
    Abstract: A seal cover includes a cover main body (10) shaped to cover an opening of a case and to be attached to a surface of the case. A seal ring holder (20A) is on the underside of the cover main body (10) and is arranged to fit into the opening. A seal ring (25) is on the outer peripheral surface of the seal ring holder (20A) and closely contacts the inner peripheral surface of the opening. An interlock connector (40) projects from the seal ring holder (20A) for connecting to the waiting connector and sets an energizing circuit in an energized state or a non-energized state upon being connected to or separated from the waiting connector. The interlock connector (40) is mounted on the seal ring holder (20A) to be movable in a direction perpendicular to a connecting direction to the waiting connector.

  • Patent number: 8678731
    Abstract: A nut (30) includes a main portion (30A) formed with a bolt insertion hole (31), into which a bolt is insertable, and a wedge portion (30B) projecting from the main portion (30A) in a radially outward direction of the bolt insertion hole (31) and having a width smaller than that of the main portion (30A). Thus, parts (27B) extending lateral to the wedge portion (30B) in parallel with a projecting direction of the wedge portion (30B) can be made thicker than parts (27A) extending lateral to the main portion (30A). Therefore, the parts (27B) that resist an accompanying rotation of the nut (30) can be thickened without enlarging a housing (20), with the result that strength against the accompanying rotation of the nut (30) can be ensured.

  • Patent number: 8366470
    Abstract: A connector has a housing with a fit-on tube that can fit in a hood of a mating connector. Terminal fittings are fixed to ends of wires and are held by the housing. A sealing ring is mounted on an annular holding groove on a peripheral surface of the fit-on tube and is disposed between the peripheral surface of the fit-on tube and an inner surface of the hood to seal a gap therebetween. Engaging grooves are formed in the peripheral surface of the fit-on tube. The engaging grooves intersect the annular holding groove and are deeper than a bottom surface of the annular holding groove. Rotation-stopping projections project from the sealing ring to extend along a direction in which the engaging grooves extend and each has an engaging claw that can fit on a bottom of one of the engaging grooves.

  • Patent number: 7988475
    Abstract: A connector assembly is provided with an electric wire-side housing (51) to be fit on a device-side connector (10) that has relay terminals (20). Guide projections (58) project out from an outer peripheral surface of a wire-deriving tube (52) of the wire-side housing (51). The guide projections (58) guide a shielding tube (71) of a shielding shell (70) in position with respect to the wire-deriving tube (52). Therefore in fixing the shielding shell (70) to a connector-mounting member (40), an inner peripheral surface of the shielding tube (71) contacts the guide projections (58) of the wire-side housing (51) to fit the shielding shell (70) on the wire-side housing (51) without dislocation.
