Exterior body for wire and a wire harness with exterior body

Abstract

An exterior body for a wire that prevents damage caused by an attachment member, and a wire harness with the exterior body are provided. This wire exterior body (3), formed by folding a resin sheet and attached to the outer periphery of a wire (a wire harness) (2), is provided with multiple wall sections (4) that extend in the direction of extension of the wire and that form a housing (5) that houses the wire. In at least one wall section (the upper lid wall section (45)) of the multiple wall sections (4), a through hole (47) which is formed passing through the resin sheet in the thickness direction and into which an attachment member (61) attachable to a vehicle body is inserted, and a groove (a lower surface groove (48) or an upper surface groove (49)) having reduced resin sheet thickness is formed in at least a portion around the through hole (47) in at least one of an upper surface (45c) and a lower surface (45d) facing in the thickness direction.

Description

technical field [0001] The present invention relates to a sheath for electric wires attached to the outer periphery of electric wires such as a wire harness, and a wire harness having the sheath. Furthermore, the present invention relates to a sheath for electric wires attached to the outer periphery of electric wires and a wire harness having the sheath, and more particularly to a sheath for electric wires having a branch portion and / or a bent portion in the extending direction of the electric wires and a wire harness having the sheath. wiring harness. Background technique [0002] As a sheath for electric wires attached to the outer periphery of electric wires arranged in vehicles, etc., there is known a protector which bends a plate material so as to double-enclose the periphery of the electric wire bundle, and forms a rectangular cylindrical housing for storing the electric wire bundle. space, thereby protecting the wire harness from external force (refer to Patent Docu...

AI Technical Summary

Problems solved by technology

[0007] However, even in Patent Document 2, there is still room for improvement in the mechanical strength of the bellows.

Furthermore, there is also the problem that not only more processing costs are required to make the corrugated structure, but also more materials are required

In addition, in Patent Document 2, since the bending allowable portion is not fixed, it is not possible to obtain workability when attaching the bent wire harness to the vehicle.
