Patent number: 10647271Abstract: A wire harness includes a cable that includes electric wires and a sheath covering the electric wires and is arranged so that the electric wires are exposed from an end of the sheath, a housing that accommodates the electric wires exposed from the end of the sheath, a sealing member arranged inside the housing, and a cylindrical holder including an elastic body and having an inner circumferential surface in contact with an outer circumferential surface of the sheath. An engaging portion provided on one of the housing and the holder engages an engaged portion provided on an other of the housing and the holder. The engagement between the engaging portion and the engaged portion restricts the housing from moving in a longitudinal direction of the cable.Type: GrantFiled: April 23, 2019Date of Patent: May 12, 2020Assignee: HITACHI METALS, LTD.Inventors: Naoya Toyoshima, Hajime Maejo

Patent number: 10501030Abstract: A wire harness includes a cable that includes a plurality of electric wires and a sheath covering the electric wires, a wire fixing portion that is formed to cover an end portion of the sheath and the electric wires extending out of the end portion of the sheath and fixes the extending directions of the electric wires, and a fixing member attaching portion to which a fixing member used for fixing the cable to a fixing target is attached. The wire fixing portion and the fixing member attaching portion are formed by resin-molding. The wire fixing portion and the fixing member attaching portion are spaced apart from each other in a cable longitudinal direction. The wire fixing portion is relatively movable with respect to the fixing member attaching portion due to flexibility of the cable between the wire fixing portion and the fixing member attaching portion.Type: GrantFiled: April 23, 2019Date of Patent: December 10, 2019Assignee: HITACHI METALS, LTD.Inventors: Naoya Toyoshima, Hajime Maejo
