[0085] Next, a second embodiment will be described with reference to the drawings. Figure 4 is a cross-sectional view showing the structure of the wire harness. Figure 5 is a cross-sectional view showing the structure of the protection member.

[0086] The second embodiment is the same as the first embodiment except that an insulating resin covering 32 described below is provided on the outer surface 34 of the protective member 20 of the wire harness 11 in the first embodiment. Therefore, the insulating resin covering 32 will be described below.

[0087] exist Figure 4 with 5 In the second embodiment, an insulating resin covering 32 is further formed on the outer surface 34 of the protective member 20 of the wire harness 31 . The insulating resin covering 32 is formed as a layer corresponding to the upper layer of the protective member 20, and is made of a resin composition having insulating properties. After the protective member 20 is molded, the insulating resin cov...

[0090] exist Figure 4 Among them, each of one ends of the braids 26 constituting the parts of the terminal shield members 22 and 23 is connected to the outer peripheral surface of the shield case 27, and the other ends of the braids 26 are respectively connected to the shield member connection portions 35 of the protection member 20. . In this embodiment, the connection of the braid 26 and the shield member connection portion 35 should be performed by welding. This should be the instance. The braid 26 and the shield connection part 35 are connected and fixed by the connection part 29 formed between the braid 26 and the shield connection part 35 . Like the first embodiment, a braid formed by weaving conductive resin fibers into a mesh shape and a shield formed of a conductive resin composition can be used as the braid 26 and the shield 27 in this embodiment. This should be instance.

[0091]In the present embodiment, the terminal shield members 22 and 23 can be connected a...

Abstract

A wire harness (10 to 13, 31) includes one or more conducting paths (19), a protective member (20) that is formed in a pipe shape, and accommodates the one or more conducting paths (19) in the protective member (20) to shield a electromagnetic wave emitted from the one or more conducting paths (19). The protective member (20) is formed of resin composition that has conductivity.

Description

technical field [0001] The present invention relates to a wire harness. Background technique [0002] The high-voltage wire harness is used to electrically connect devices of a hybrid vehicle or an electric vehicle, that is, devices such as a motor unit, an inverter unit, or a battery. [0003] The wire harness disclosed in Patent Document 1 includes: three electric wires, which are electrically connected between devices; a main shield, which accommodates most of the entire length of the three electric wires; and a sub-shield, which The sub-shield extends from the end of the main shield and covers the three electric wires. Depending on where the equipment is installed, the routing path of the harness may become very long. [0004] Each end of the three wires is provided with a terminal fitting. After the wire harness is manufactured, the terminal fittings are adapted to be inserted into the shielding case of the device together with the end portions of the electric wires,...
