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.

Abstract

This conductive line (L) comprises a single-core cable (4) formed by encasing a single conductor (6) in a coating (7), and a twisted cable (5) formed by twisting together a plurality of base lines (9) and encasing the base lines (9) in a coating (10), wherein one of the two ends in the direction of length of the single-core cable (4) has the coating (7) peeled away and the conductor (6) is exposed. The exposed conductor (6) has formed therein a pressed portion (8) that has been pressed into a flat shape. The base lines (9) exposed at the end of the twisted cable (5) are joined onto the pressed portion (8) by ultrasonic welding.

Description

technical field [0001] The invention relates to a conductive wire and its wiring structure. Background technique [0002] In a hybrid vehicle or an electric vehicle, the battery and the electric motor (inverter) are connected by conductive wires. The structure of the following patent document 1 is known as such a wiring structure of a conductive wire. In the wiring structure disclosed herein, the battery installed on the rear side of the vehicle and the inverter installed in the engine room are connected by three wires. A metal shielding pipe is arranged under the floor of the vehicle, and conductive wires are inserted into the shielding pipe. The shield pipe is bent along the shape of the predetermined wiring path, and its front end side is led into the engine room, and extends to the vicinity of the inverter. The wiring path from the shield tube to the inverter is relatively short, and if it cannot be bent freely, the connection work will become difficult. Therefore, a ...
