Problems solved by technology

[0008] In this way, when the straight portion deforms following the shape of the wire harness, in the wiring state connected to the connection partner, a pulling force for deflection and deformation acts on the wire harness, which may cause disconnection as described above and fail to ensure electrical connectivity.

Abstract

The invention provides a conduit capable of reliably guide a wire harness in a desired wiring direction. The conduit is composed of tubular conduit main body (10) and an internal part (20). The internal part (20) is disposed in corner covers (12) disposed at two ends of a linear part (11) of the conduit main body (10), the shape retention of the internal part (20) is higher than the shape retention of the conduit main body (10), a cross section of the linear part (11) of a penetrating and inserting wire harness (WH) of the conduit (1) forms a circle, and the linear part (11) is composed of a cylinder part (13) disposed at the center of the length direction and corrugated parts (14) disposed on two sides of the cylinder part (13).

Description

technical field [0001] The present invention relates to a wire protection tube, which is composed of an internal part inserted into a through hole formed in a partition wall such as a body panel of an automobile, and a tubular wire protection tube main body through which a wire harness is inserted, so as to make the wire harness waterproof. Performance and dust resistance are improved. Background technique [0002] In order to improve the waterproof performance and dustproof performance of the wire harness that passes through the through hole formed in the partition wall and is routed along the partition wall, the tubular grommet main body installed along the partition wall and the through hole installed in the partition wall The internal part uses the grommet that penetrates the wire harness inside for multiple branches. [0003] In addition, in recent years, with reduction in weight and space saving of vehicles, the wiring harness itself has been required to be compact, a...
