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 portion of the sheath, a housing that accommodates the electric wires exposed from the end portion of the sheath, wire seal members arranged inside the housing to seal between the electric wires and the housing, a holder that includes an elastic body, a cylindrical sheath-side cylinder portion including an inner circumferential surface in contact with an outer circumferential surface of the sheath, and a cylindrical housing-side cylinder portion in contact with an outer circumferential surface of the housing, the sheath-side cylinder portion and the housing-side cylinder portion being integrally formed, and a first pressing member that presses the housing-side cylinder portion toward the housing and thereby fixes the housing-side cylinder portion to the housing.

Wire harness

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.

[Problem] Provided are a composite cable and a composite harness that allow the improvement of cable termination workability while maintaining the flex resistance. [Solution] A composite cableis provided with a pair of first electric wires, a twisted pair wireformed by twisting a pair of second electric wireshaving a smaller outer diameter than the first electric wiresand a tape memberspirally wound around an assembled articlethat is formed by twisting the pair of first electric wiresand the twisted pair wiretogether, wherein a twist direction of the twisted pair wireis different from a twist direction of the assembled article, and the twist direction of the assembled articleis different from a winding direction of the tape member

Composite cable and composite harness

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.

Wire harness and method for manufacturing the same

A composite cable is provided that improves terminal machinability while maintaining bending resistance. The composite cable is provided with: a pair of first electric wires; a twisted-pair wire obtained by twisting together a pair of second electric wires having an outer diameter that is smaller than that of the first electric wires; and a tape member spirally wrapped around an aggregate obtained by twisting the pair of first electric wires together with the twisted-pair wire. The twisting direction of the twisted-pair wire, the twisting direction of the aggregate, and the wrapping direction of the tape member are all the same direction.

A vehicle composite cable includes a pair of power wires for supplying a current to an electric parking brake unit that generates a braking force after stopping a vehicle, a first signal line including a twisted pair wire transmitting a first electrical signal during when the vehicle is in motion, a second signal line including a twisted pair wire for transmitting a second electrical signal also during when the vehicle is in motion, and a sheath collectively covering the pair of power wires and the first and second signal lines. The first and second signal lines are not covered with a shield conductor, and the first signal line is separated from the second signal line by the pair of power wires.
