Examples
Embodiment 1
[0032] The conductive wire L of this embodiment is suitable for a hybrid vehicle. The battery 1 mounted on the rear side of the vehicle and the inverter 2 installed in the engine room are connected by a wire harness WH. In the case of this example, if Figure 4 As shown, the wire harness WH is composed of three conductive wires L.
[0033] The wire harness WH is collectively inserted into the shield pipe 3 arranged under the floor of the vehicle. More specifically, the rear end side of the shield pipe 3 is introduced into the rear suspension side of the vehicle compartment, and a metal braid 13 to be described later is interposed between the shield pipe 3 and the battery 1 . The middle of the shield pipe 3 extends substantially horizontally under the floor of the vehicle along the front-rear direction. Its front end is bent upward and introduced into the engine room, and extends toward the inverter 2 .
[0034] The shielding tube 3 is made of aluminum or an aluminum alloy,...
Embodiment 2
[0048] Figure 5 Example 2 of the present invention is shown. In Embodiment 1, the mode in which the conductor 6 exposed at the front end of the single-core wire 4 and the wire 9 exposed at the rear end of the twisted wire 5 are bonded and connected by ultrasonic welding is shown, but in Embodiment 2 connection by riveting. That is, the portion of the conductor 6 exposed from the single-core electric wire 4 is crushed and spread sufficiently in the width direction to form a pair of crimped portions 6A. The wire rod 9 portion of the twisted electric wire 5 is placed on the crushed portion 8 formed in this way, and both sides in the width direction are bent inward together and caulked. In this way it is also possible to connect single-core wires 4 and stranded wires 5 .
[0049] The other structures are the same as those in Embodiment 1, and can also exert the same effects.
Embodiment 3
[0051] Image 6 Example 3 of the present invention is shown. In Example 2, the cross section of the conductor 6 was formed square and the wire 9 was riveted, but in Example 3 the cross section was formed circular and the wire 9 was riveted.
[0052] The other structures are the same as in Embodiments 1 and 2, and can also exert the same effect.
