ブルを生ずる難点がある。The above-mentioned conventional corrugated pipe for wire harness maintains the straight-bendable disposition posture of the wire harness and protects the electric wire from being damaged by contact with the vehicle body or other members. Although it has an electric wire protection function to prevent it, there is an electric wire insertion slit that cuts the pipe wall in a straight line, so the electric wire insertion slit is not located below the pipe body in the installation and locking posture to the vehicle body etc. And, the splash water and rainwater when the vehicle is running from the slit infiltrate the inside of the corrugated pipe and accumulate in the pipe, or the infiltrated water flows through the pipe and flows out from the pipe end to the vehicle space, causing electrical troubles and inundation troubles. There are difficulties.

のである。Since the corrugated pipe is arranged in the vehicle body or the like in a narrow space in which the condition of the vehicle body or the like is given priority, the electric wire insertion slit is intentionally restricted downward. Becomes difficult. Therefore, it is practically difficult to prevent the above-mentioned waterlogging trouble by restricting the mounting posture on the vehicle body, etc., and if the stored electric wire has a connection part that is vulnerable to waterlogging, special waterproofing measures should be taken for the connection part. Therefore, the molding workability of the electric wire to be housed in the corrugated pipe is lowered and the cost is increased. The present invention provides a corrugated tube for a wire harness that solves the above-mentioned drawbacks of the prior art.

In a corrugated pipe for a wire harness, which is made of a flexible pipe continuously provided in the longitudinal direction of the pipe, the pipe wall is incised, and a spiral electric wire insertion slit is provided around the pipe. That is, the spiral-shaped wire insertion slit is based on the idea of making the wire insertion port into which the wire is elastically opened to insert the wire and the drainage hole of the water in the pipe to be multifunctional, and the spiral pitch is within a range that does not hinder the wire insertability. At the inner,
The pitch is set as small as possible.

In addition, since it is located below the circumference of the pipe in the installation posture, the wire insertion slit in the downward position functions as a drain hole due to the gravity of the water in the pipe, effectively preventing the water in the pipe from accumulating. Has a function of draining water.

That is, in the corrugated pipe 1 of the automobile wire harness in which the pipe wall 4 is bulged outwardly, and the ridge ring portions 2 forming a concentric circle with the pipe body are continuously provided in the longitudinal direction of the pipe body at a fine pitch. The pipe 1 has a spirally continuous electric wire insertion slit 3 formed by cutting the pipe wall 4, and the electric wire insertion slit 3 serves as an insertion port when the electric wire 6 is housed in the pipe and also serves as a drainage hole for water in the pipe. It has a functional structure.

勢の保持と電線６の保護を図るようになっている。More specifically, the wire insertion slit 3 is provided in the pipe wall 4 in a spiral shape capable of accommodating the wire 6 of the wire harness by elastically opening with an opening tool (not shown). In the free state after housing, the tube wall 4 has a shape in which streak-like minute voids are present between the opposed wall surfaces. Then, similarly to the conventional corrugated pipe, after the electric wire 6 is housed, the electric wire 6 is aligned with the arrangement form on the vehicle body, and is formed into a straight bendable shape. It is designed to hold and protect the electric wire 6.

作業が解消できる。Even if the corrugated tube 1 is randomly arranged without restricting the position of the wire insertion slit 3 by giving priority to the condition of installation on the vehicle body, the corrugated tube 1 in the installation posture is For each spiral pitch of the wire insertion slit 3,
Since there is a downward position 5 of the wire insertion slit 3 that faces downward in the disposition attitude (see (C) and (D) of FIG. 1).
Water entering the inside of the pipe from the electric wire insertion slit 3 that is directed upward or obliquely upward is gravity discharged from the downward position 5 that is present nearby, and is quickly drained without being accumulated in the pipe. Therefore, the trouble caused by the water in the pipe can be solved, and the complicated work of applying a special waterproofing measure to the connecting portion of the electric wire 6 can be solved.

ハーネスの電線成形性を向上する効果がある。As described above, the corrugated pipe for a wire harness of the present invention effectively prevents drainage of water in the corrugated pipe and collects the accumulated water, thereby preventing various troubles due to the accumulated water in the pipe. There is an effect that the protection performance of the electric wire is stably improved, and that special waterproofing measures for the stored electric wire are made unnecessary and the electric wire formability of the wire harness is improved.
