Publication number: 20100261365Abstract: Guide projections (58) project out from an outer peripheral surface of a wire-deriving tube (52) of a 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.Type: ApplicationFiled: April 6, 2010Publication date: October 14, 2010Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Kouji Sakakura

Publication number: 20100261363Abstract: 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.Type: ApplicationFiled: April 1, 2010Publication date: October 14, 2010Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Kouji Sakakura

Patent number: 7811116Abstract: A connector is provided with terminals (11) to be connected with terminals (32) of a mating connector (30) by bolting and a nut accommodating portion (20) for accommodating nuts (17) for bolting. An entrance (20A) enabling the insertion and withdrawal of the nuts (17) is formed at a connection surface side of the nut accommodating portion (20) with the mating connector. A nut cover (40) for preventing the nuts (17) from coming out through the entrance (20A) is detachably attachable to the nut accommodating portion (20) and includes inverted insertion preventing portions (46) for permitting a connection with the mating connector (30) when the mating connector (30) is in a proper orientation while coming into contact with the mating connector (30) to prevent the connection when the mating connector (30) is not in the proper orientation.Type: GrantFiled: July 2, 2009Date of Patent: October 12, 2010Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Kouji Sakakura, Daisuke Akuta

Publication number: 20100034613Abstract: 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.Type: ApplicationFiled: July 27, 2009Publication date: February 11, 2010Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Kouji Sakakura, Hiroyuki Matsuoka

Patent number: 7264508Abstract: A shielded connector assembly has first and second housings (11, 31). The first housing (11) has a fitting space (17) formed with coupling ribs (16). A shielding shell (26) is in the fitting space (17) and has slits (27) that receive the coupling ribs (16). A preventing groove (29) is formed in a peripheral surface of a fitting space (17) and receives a projection (37) of the second housing (31) when the housings (11, 31) are connected properly. The preventing groove (29) is aligned with the slit (27) so that the slit (27) also receives the projection (37). Thus, it is unnecessary to form a separate notch to receive the projection (37).Type: GrantFiled: January 26, 2006Date of Patent: September 4, 2007Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Kouji Sakakura, Tetsuya Shinozaki

Patent number: 7238050Abstract: A connection shell (23) includes a tubular fastener (25) formed by flat surfaces (25a) and curved surfaces (25b) and a rectangular tubular contact (24). A crimp ring (29) is crimped to fasten a wire shield (28) to the outer peripheral surface of the tubular fastener (25). The tubular contact (24) is connected so that a circumferential surface thereof overlaps a circumferential surface of a housing shell (19). The tubular contact (24) has a rectangular shape that conforms with the rectangular tubular shape of the housing shell (19). Thus, only a small clearance is defined between the housing shell (19) and the connection shell (23) to suppress leakage of noise through the clearance between the housing shell (19) and the connection shell (23).Type: GrantFiled: January 30, 2006Date of Patent: July 3, 2007Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Kouji Sakakura, Tetsuya Shinozaki

Patent number: 4846497Abstract: An automatic seatbelt system for a vehicle, which is designed to restrain the body of an occupant when an emergency situation of the vehicle occurs, has a slider which retains one end of a webbing and which is movable along a guide rail laid on the body of the vehicle between a position at which the webbing is fastened to the occupant's body (hereinafter referred to as a "webbing fastening position") and a position at which the webbing is unfastened therefrom (hereinafter referred to as a "webbing unfastening position"), and a continuous member for moving the slider between the above-described two positions. The continuous member and the slider are allowed to move relative to each other by a predetermined amount.Type: GrantFiled: December 1, 1987Date of Patent: July 11, 1989Assignee: Kabushiki-Kaisha Tokai-Rika-Denki-SeisakushoInventors: Kenji Matsui, Tatsuo Yamashita, Hideki Tanaka, Kouji Sakakura
