Patent number: 10077013Abstract: A wire harness and an electric wire protecting pipe that can protect electric wires without including a separate component for shielding a drain hole. The electric wire protecting pipe is a resin pipe into which electric wires are insertable, and a lower wall portion is provided integrally with a projecting portion that projects outward, and a circumferential wall portion of the projecting portion is provided with a drain hole. According to such a configuration, the electric wires are protected from flying gravel, splashing water, or the like, by the projecting portion that is formed integrally with the electric wire protecting pipe, and thus the electric wires can be protected without including a separate component for shielding the drain hole.Type: GrantFiled: November 28, 2014Date of Patent: September 18, 2018Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hidetoshi Sugino, Hidehiko Iwakawa

Patent number: 9923348Abstract: A wire harness and an electric wire protecting pipe that can prevent holes from being formed by flying gravel while the vehicle is moving and includes a bending pipe portion that can be bent easily. The electric wire protecting pipe is a resin pipe into which electric wires are insertable, and includes a bending pipe portion that is easily bent and is provided with protruding portions and recessed portions that are alternately continuous with each other in an axial direction, and a straight pipe portion that is flat and is not easily bent in the axial direction. A thickness of a lower wall portion that is disposed on a lower side when the electric wire protecting pipe is attached to a vehicle is greater than a thickness of a left wall portion and a right wall portion.Type: GrantFiled: November 28, 2014Date of Patent: March 20, 2018Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hidetoshi Sugino, Hidehiko Iwakawa

Patent number: 9676348Abstract: A shield conductive path may include a tubular shield portion that surrounds a plurality of electric wires. The shield conductive path may further include a partition portion that partitions an interior space of the shield portion into a plurality of electrical wire insertion paths. A specific electrical wire may be inserted through a specific electrical wire insertion path of the plurality of electrical wire insertion paths and may be guided out from a guiding-out opening formed in the shield portion, to the outside of the shield portion, and this guiding-out opening can be formed within an area, of the shield portion, provided with the partition portion.Type: GrantFiled: February 10, 2015Date of Patent: June 13, 2017Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Hidetoshi Sugino, Masanori Kuwahara, Hidehiko Iwakawa

Patent number: 9504193Abstract: A shielded conductive path that can facilitate manufacturing operations is provided. A shielded conductive path includes a shielding pipe that is configured to have a tubular shape into which an electric wire can be inserted, by combining together a pair of divided bodies into which the shielding pipe is divided along its axis, and an overlapping fitting portion that is provided at a joint portion of the pair of divided bodies and allows the pair of divided bodies to be fitted to each other while overlapping each other in an inside-outside direction when the pair of divided bodies are combined together. Thus, the operations for manufacturing the shielded conductive path can be performed easily.Type: GrantFiled: February 11, 2015Date of Patent: November 22, 2016Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Hidetoshi Sugino, Masanori Kuwahara, Hidehiko Iwakawa

Publication number: 20150263496Abstract: Embodiments of the present application are directed to a shield conductive path that can reduce the height of a shield pipe, and eliminate the need of installation of new equipment. A shield conductive path includes a metal shield pipe that surrounds and shields an electrical wire, and has the cross-sectional shape such that a portion on the upper or lower side of the shield pipe when it is arranged in a vehicle is cut away, and the remaining portion has a shape that corresponds to the shape of a substantially perfect circle. With this, it is possible to reduce the height of the shield pipe, and to eliminate the need of installation of new equipment.Type: ApplicationFiled: February 20, 2015Publication date: September 17, 2015Inventors: Hidetoshi SUGINO, Masanori KUWAHARA, Hidehiko IWAKAWA

Patent number: 6464538Abstract: A connector body 30 to be fixed to a motor case 51 is formed of an aluminum die cast, and is provided, on one of side surfaces thereof, with a cylindrical housing portion 31 for inserting a terminal of a motor cable 10 to be a shielding electric wire. A double enveloping contact 33 is fitted in the housing portion 31 and an eye-ball shaped fixing portion 37 protruded from a front edge thereof is fixed, with a bolt 40, to a fixing base 45 provided integrally on the direct inside of the housing portion 31. A terminal fixture 15 of the terminal of the motor cable 10 is inserted from the housing portion 31 into the connector body 30, and is connected to the other bus bar 50, and a shield shell 21 fitted and attached into a terminal of a shield layer 13 elastically comes in contact with the inner periphery of the contact 33. A reliable electrical connection is obtained between the contact 33 and the housing portion 31 so that a shield function can be displayed effectively.Type: GrantFiled: March 6, 2001Date of Patent: October 15, 2002Assignees: Autonetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Sho Miyazaki, Hidehiko Iwakawa, Masanori Wakui, Keiichi Ito, Kazuyuki Shiraki
