CN-122003790-A - Wire harness

Abstract

A wire harness (1) is provided with a flat wiring member (100) formed in a U-shape, a first housing (10) which holds a first portion (110), a second housing (20) which holds a second portion (120), and a rotating structure (60) which can engage the flat wiring member with each other by forming the flat wiring member in a straight shape, wherein the flat wiring member in the straight shape has a first folded-back portion (150) in which an intermediate portion is folded back along a folded-back line along an extending direction (X) of the first portion, and a second folded-back portion in which the second portion is folded back along a folded-back line orthogonal to the extending direction, and wherein the rotating structure is configured to form the second folded-back portion in the second portion by rotating the first housing and the second housing relative to each other.

Description

Wire harness Technical Field The present invention relates to a wire harness. Background Conventionally, there are flat wiring materials such as flexible printed boards. Patent document 1 discloses a flexible printed circuit board capable of easily realizing long wiring. The flexible printed circuit board of patent document 1 includes a first belt-like member and a second belt-like member each having a conductive portion and an insulating portion covering the conductive portion, and a first connecting member connecting a first end portion of the first belt-like member and a first end portion of the second belt-like member. Prior art literature Patent literature Patent document 1 (Japanese patent application) JP 2015-170699A Disclosure of Invention Technical problem to be solved by the invention It is desirable to be able to elongate a flat wiring member formed in a U-shape into a straight line shape. When a flat wiring member formed in a U-shape is used, the manufacturing cost and the installation cost of the flat wiring member can be reduced. The invention aims to provide a wire harness capable of lengthening a flat wiring member formed into a U shape into a linear shape. Technical scheme for solving technical problems The wire harness of the present invention includes a flat wiring member formed in a U-shape having a linear first portion, a linear second portion, and an intermediate portion connecting an end of the first portion and an end of the second portion, a first housing holding the first portion, a second housing holding the second portion, a rotating structure for relatively rotating the first housing and the second housing, the first housing and the second housing being capable of engaging the flat wiring member with each other in a linear shape, the second portion extending on an extension line of the first portion in a planar view, the linear flat wiring member having a first folded portion and a second folded portion at the first folded portion, the intermediate portion being folded back along a folded back line extending in an extending direction in which the first portion extends, and the second housing being formed in a rotating structure for relatively rotating the second housing in a direction in which the intermediate portion of the second portion is folded back and the second housing are formed in a state in which the second folded back line is orthogonal to the first folded back line. Effects of the invention A wire harness includes a flat wiring member formed in a U-shape, a first housing that holds a first portion of the flat wiring member, a second housing that holds a second portion of the flat wiring member, and a rotating structure that rotates the first housing and the second housing relative to each other, wherein the first housing and the second housing can be engaged with each other while the shape of the flat wiring member is set to a linear shape. The rotating structure is configured to form a second folded portion in a second portion of the flat wiring member by relatively rotating the first housing and the second housing. According to the wire harness of the present invention, the flat wiring member formed in the U-shape can be elongated into a straight shape.
