[0063] Hereinafter, a first embodiment will be described with reference to the drawings. figure 1 is a drawing about the wire harness of the present invention, figure 1 (a) is a schematic diagram showing an arrangement example, figure 1 (b) is a perspective view showing the bend and the line holder, figure 1 (c) is a side view of the bend and the line holder when viewed from the direction A, while figure 1 (d) is a side view of the bend and the line holder viewed from the B direction.

[0064] In this embodiment, an explanation will be given regarding an example of the wire harness of the present invention used for a hybrid vehicle (also an electric vehicle).

[0065] exist figure 1In (a) to (d), reference numeral 1 denotes a hybrid vehicle. The hybrid vehicle 1 is a vehicle that mixes the power of an engine 2 and a motor unit 3 and drives the vehicle. Electric power is supplied from a battery 5 (battery pack) to the motor unit 3 via the inverter unit 4 . In the present...

[0083] Hereinafter, a second embodiment will be described with reference to the drawings. figure 2 (a) and 2(b) are a perspective view and a side view showing another embodiment of the bent portion. In addition, constituent elements similar to those in the first embodiment described above are assigned similar reference numerals, and thus will not be described in detail.

[0084] exist figure 2 In (a) and 2(b), in the wire harness 31 of the second embodiment, the bending object held by the wire holder 17 is different from that of the first embodiment. In other words, the holding object of the line holder 17 is the bent portion 33 of the wire bundle 32 in which a plurality of wires (lead wires) are bundled.

[0085] In the bent portion 33 , reference numeral 34 denotes an outer curvature forming portion on the side where the degree of curvature R is larger. In addition, reference numeral 35 denotes an inner curvature forming portion on the side where the degree of curvature...

[0088] Hereinafter, a third embodiment will be described with reference to the drawings. figure 2 (c) and 2(d) are perspective and side views showing another embodiment of the line holder. In addition, constituent elements similar to those in the first embodiment described above are assigned similar reference numerals, and thus will not be described in detail.

[0089] exist figure 2 In (c) and 2(d), the wire harness 41 is configured to include the wire assembly 15 , the outer member 16 provided outside the wire assembly 15 , and the wire holder 42 . The line keeper 42 of the third embodiment is different from that of the first embodiment.

[0090] The line holder 42 is a member that holds the bend of the bending portion 20 and holds the course of the wire harness 41 , and is formed by bending a slat having rigidity. Although the final holding shapes are different from each other, this line holder 42 is used in the same way as the line holder 17 of the first embodiment. ...

Abstract

The invention provides a wire harness that is low cost and has versatility regarding a wire holding. In a wire harness, a wire holder 17 is used to hold wires. The wire holder 17 is formed by bending a strip with stiffness. The wire holder 17 has a pair of retaining arms 24 that retain opposite ends of the bending part 20 respectively and a connecting arm 25 that connects the retaining arms 24. In the flexing portion 25, a first unbending stopper 26 of which an intermediate part is contacted at an inside curvature forming portion 22 closer than an outside curvature forming portion 21 of the bending part 20 is formed.

Description

technical field [0001] The invention relates to a wire harness with a line holding function. Background technique [0002] A wire harness disclosed in Patent Document 1 below is configured to include three high-voltage electric wires and three metal protection tubes that house and protect each of the three high-voltage electric wires. High-voltage wires are provided to interconnect the motor installed at the front of the vehicle and the inverter installed at the middle or rear of the vehicle. [0003] The wire harness is routed through the floor body of the vehicle outside the vehicle frame. Therefore, a metal protection tube is formed to protect the high-voltage wires from stone splashes or water splashes. The metal protection tube has rigidity to protect the high-voltage electric wire from stone splash or water splash and prevent the high-voltage electric wire from being bent. At the same time, since the metal protection tube is made of metal, it also has an electromagn...
