Problems solved by technology

[0006] However, as described above, the wire harness in which the electric wires are surrounded by the hard resin tube in which the straight pipe portion and the corrugated portion are integrally formed, since the corrugated portion can be bent freely, it is easy to deform tracklessly from the corrugated portion when mounted on a vehicle.
Therefore, there is a problem that it is not easy to attach to the vehicle while maintaining the shape.

Embodiment Construction

[0014] Preferred embodiments of the present invention are shown below.

[0015] In the electric wire sheathing material of the present invention, the corrugated portion may extend integrally in the axial direction from the end portion of the straight pipe portion. According to such a configuration, the corrugated portion can be bent freely, and the connection work of the wire harness can be easily performed.

[0016] In addition, the wire sheathing material of the present invention may include a braided wire formed in a cylindrical shape from a plurality of metal wires, and the braided wire is arranged inside the above-mentioned resin tube to surround the above-mentioned wire, or is arranged to surround the above-mentioned resin tube. On the outside of the above-mentioned resin tube.

[0017] According to this configuration, the entire length of the electric wire is shielded by the braided wire. Here, when shielding the portion passing through the metal pipe with the metal p...

Abstract

An electric wire sheathing member including a resin pipe that can be easily attached to a vehicle, and a wire harness are provided. The electric wire sheathing member includes a resin pipe, the resin pipe including a straight tube portion that has a tubular shape into which an electric wire can be inserted and whose cross-sectional shape is constant in an axial direction, a bellows portion that has a tubular shape into which the electric wire can be inserted and in which ridge portions and valley portions are repeated in an axial direction, and a bent portion that is formed by bending the straight tube portion into a predetermined shape. With this configuration, the straight tube portion is not flexible like a corrugated tube having a bellows shape is, and therefore, the shape of the bent portion is retained. Accordingly, the wire harness can be easily attached to a vehicle.

Description

technical field [0001] The present invention relates to a wire sheath and a wire harness. Background technique [0002] Conventionally, a technique is known in which electric wires routed in a wiring harness such as a chassis of a vehicle are inserted into a cylindrical wire sheathing material to protect them. In the wire harness described in, for example, Patent Document 1 below, a metal pipe is used as an electric wire sheathing material, and a wiring path of electric wires is also held. The metal pipe is bent into a predetermined shape by a pipe bender. [0003] In addition, there is known a wire harness in which the weight of a vehicle is reduced by replacing the above-mentioned metal pipe with a resin pipe. In the wire harness described in, for example, Patent Document 2 below, the entire length of the electric wires is surrounded by a tube made of hard resin in which a straight tube portion and a corrugated portion are integrally molded. The wire harness is attached...
