(First embodiment)
Hereinafter, 1st Embodiment of a wire harness is described according to drawing. In each drawing, a part of the configuration may be exaggerated or simplified for convenience of explanation. Further, the dimensional ratio of each part may be different from the actual one.

  A vehicle V shown in FIG. 1 includes a high voltage battery 11 and an inverter 12 that are electrically connected by a wire harness 10. In this example, an inverter 12 is provided in front of the vehicle V, and a high voltage battery 11 is provided at the rear of the vehicle V. For example, the wire harness 10 is routed so as to pass under the floor of the vehicle. The inverter 12 is connected to a wheel driving motor (not shown) serving as a power source for vehicle travel, generates AC power from DC power of the high voltage battery 11, and supplies the AC power to the motor. The high voltage battery 11 is a battery capable of supplying a voltage of several hundred volts.

  As shown in FIG. 2, the wire harness 10 includes two high-voltage wires 13 and 14 that are respectively connected to the plus terminal and the minus terminal of the high-voltage battery 11, and an exterior member 15 that surrounds the outside of each of the high-voltage wires 13 and 14. It has.

(High voltage wire)
The high-voltage wires 13 and 14 are provided with connectors C1 and C2 (see FIG. 1) at both ends thereof to electrically connect the high-voltage battery 11 and the inverter 12. The high voltage electric wires 13 and 14 have core wires 13a and 14a and coatings 13b and 14b made of an insulating member that covers the outer sides of the core wires 13a and 14a.

The exterior member 15 includes an electromagnetic shield part 20, a corrugated tube 30, a water stop member 40, and a connection member 50.

  The metal pipe 21 is mainly disposed under the floor of the vehicle V, and braid members 22 are provided at both ends thereof. In FIG. 2, the vicinity of one end of the metal pipe 21 is shown.

  The metal pipe 21 is made of, for example, an iron-based or aluminum-based metal material. The metal pipe 21 is routed under the floor of the vehicle V and may be bent into a predetermined shape according to the configuration of the floor. The metal pipe 21 collectively shields the high-voltage electric wires 13 and 14 inserted therein and protects the high-voltage electric wires 13 and 14 from stepping stones and the like.

  The braided member 22 is a cylindrical member configured by braiding a plurality of metal strands. In the braided member 22 of the present embodiment, each metal strand can be composed of an iron-based or aluminum-based metal material that is the same metal material as the metal pipe 21. The outer periphery of the braided member 22 is surrounded by the corrugated tube 30.

  The corrugated tube 30 has an inner diameter in the recess 32 that is substantially the same as or slightly larger than the outer diameter of the metal pipe 21. Therefore, the end portion of the metal pipe 21 can be inserted into the corrugated tube 30.

Between the corrugated tube 30 and the metal pipe 21, the braided member 22 and the water stop member 40 are provided.
As shown in FIG. 2, the water stop member 40 is made of, for example, a rubber material and is configured to have a substantially annular shape. The water stop member 40 is provided on the end side of the corrugated tube 30 relative to the braided member 22, that is, on the inlet side of water or the like. It arrange | positions so that it may contact | abut in the insertion direction of 13,14. In other words, the entire water stop member 40 is positioned closer to the end of the corrugated tube 30 than the braided member 22 on the side where the metal pipe 21 is inserted. Therefore, the water stop member 40 does not overlap (do not contact) the braided member 22 in the radial direction. That is, in the present embodiment, the entire water stop member 40 corresponds to a non-overlapping portion.

The water stop member 40 is held between the metal pipe 21 and the connection member 50 by the connection member 50 together with the braided member 22 and the corrugated tube 30.

It is formed by a method of plastically deforming so as to have a diameter. As an example of such a method, there is a spinning process or a swaging process. More specifically, the corrugated tube 30, the braided member 22, and the water stop member 40 are interposed between the connecting member 50 and the metal pipe 21 so as to reduce the diameter using the method described above. 52 is formed. For this reason, the groove part 54 will be formed in the outer peripheral surface 53 of the connection member 50 in the position corresponding to the said protrusion 52 over the whole circumferential direction. That is, the outer diameter of the connection member 50 in the portion where the protrusion 52 is formed is smaller than the outer diameter of the connection member 50 in the portion where the protrusion 52 is not formed. Further, the protrusion 52 of this example is formed such that the amount of protrusion from the inner peripheral surface 51 is substantially constant in the circumferential direction.

The protrusion 52 is provided on the inner peripheral surface 51 by reducing the diameter of a part of the connection member 50 using the method described above, for example, with the 40 interposed. The protrusion 52 is configured to protrude from the inner peripheral surface 51 of the connection member 50 toward the corrugated tube 30 that is radially inward. For this reason, the braided member 22 is held in a pressed state between the protrusion 52 and the metal pipe 21, and the metal pipe 21 and the braided member 22 are electrically connected.
