A wire harness that is capable of protecting a wire even if a pipe is damaged includes: a wire disposed in a pipe; and a protective material surrounding and protecting a predefined portion of the wire, the predefined portion being disposed within the pipe. This configuration places the protective material on a portion that is likely to be damaged in the event of, for instance, a collision of a vehicle, thereby capable of protecting the wire even if the pipe is damaged. This configuration is also capable of avoiding the diameter of the pipe being increased for the process of passing the wire through the pipe, because the wire in this configuration is passed through the pipe with greater ease than a wire surrounded by a protective material along its entire length of the wire.

Wire harness with wire and protective material

A wire harness including a metal pipe into which an electrical wire is inserted, a metal braided section that covers the electrical wire drawn out from the metal pipe and is formed by braiding metal bare wires that are made of a different type of metal from that of the metal pipe, and a joint pipe to one end of which the metal pipe is connected and to the other end of which the metal braided section is connected. The joint pipe is made of the same type of metal as the metal braided section or of an insulating material.

Wire harness

Core shield pipes and one collectively encasing braided shield tube are fixed and electrically connected using a metal bracket and a metal clamp. The metal bracket has two semi-circular members formed by dividing a circular plate sized to be covered by the collectively encasing braided shield tube into two parts. Semi-circular pipe insertion grooves are provided side by side at intervals on facing sides of the semi-circular members to face each other and the core shield pipes are inserted respectively into the pipe insertion grooves. The collectively encasing braided shield tube is mounted to cover the outer periphery of the metal bracket formed of the semi-circular members and the metal clamp is fastened to the outer periphery of the collectively encasing braided shield tube.
