Description

[Detailed description of the invention] [Industrial application field] This invention is a bending-molded protector made of a synthetic resin material having locking claws for arranging a wire harness, etc. to a steel plate body of a vehicle such as an automobile. The present invention relates to a wire harness protector used for straightening wire harnesses.

[Prior Art] Conventionally, in the structure of a wire harness protector 10' used in automobiles, etc., a wire harness protector 10' has a substantially linear portion 25' having a substantially U-shaped cross section and a substantially fixed shape as shown in FIGS. 8 and 10. A protector 10' in which bent parts 20' are formed into an S-shape,
As shown in FIG. 9, a salt vinyl tape was wrapped around one side of the wire harness W for straightening purposes, and was put into practical use.

Further, the modified conventional examples shown in FIGS. 10 and 11 will be specifically explained. This conventional Z-shaped protector 10'' for wire harnesses used in automobiles, etc. has a substantially straight portion 25' having a Z-shape and a substantially U-shaped cross section;
This is a Z-shaped molded protector 10'' formed with two substantially fixed bent portions 20'.Protectors 10', 10'' formed into an S-shape or a Z-shape for such wire harnesses are The wire harness W is cut to a predetermined length, and a vinyl chloride tape is wrapped around one side of the wire harness W for straightening, etc., and used to restrict the protrusion of the wire harness W.

A method of controlling and correcting the protrusion of the wire harness W, and using a protector 10', 10'', etc. having a U-shaped cross section by wrapping vinyl chloride tape around one side of the wire harness W. was common.

However, even if the taping method is put to practical use, even if the protection of one side of the wire harness W is sufficient, it is difficult to fix the wire harness W when it is attached.
The disadvantages were that there were individual variations and that it took too many man-hours to attach them. Also, the appearance of the finished product could not be called good.

[Purpose of the invention] Therefore, in this invention, we improved the time-consuming method for protecting the wire harness and fixing it at the time of attaching it, and created a bending molded protector. A bendable bellows-shaped part is provided in the middle, and after molding, it is folded and sometimes bent as needed. and,
On the one hand, it is an object of the present invention to provide a wire harness protector in which a necessary bent shape can be obtained by fitting a lid body.

The next purpose of this invention is to provide a bending molded protector made of a synthetic resin material, which has a locking pawl for arranging a wire harness, etc., and a locking receptacle at a corresponding position on one side. The first bending molding is provided with a substantially U-shaped cross section, and the locking pawls are arranged in pairs on both outer sides of the joint end face. The same molded protector as the protector is provided with a substantially U-shaped cross section, and engagement receiving portions are arranged in pairs on the outside of the joint end surface at positions corresponding to the locking claws of the first bending and bending molded protector. A second bellows-shaped molded protector is provided, in which a bellows-like shape that can be expanded and contracted is arranged in a section corresponding to the bending shape range of the first bending-shaped protector, and both ends are open. A wire harness or the like is disposed on a steel plate body of a vehicle, and the present invention is used in combination with a split-type harness protector suitable for straightening the wire harness.

[Structure of the invention] That is, the gist of the protector for an automobile wire harness of this invention is that the wire harness is held in a predetermined shape in order to arrange the wire harness etc. on the steel plate body of a vehicle such as an automobile. A bend-molded protector made of a synthetic resin material, which has a U-shaped cross section, the entire body is L-shaped or V-shaped, and locking claws are arranged to face each other on the outside of the joint end surface. The first bending-molded protector is approximately U-shaped in cross section, and there is a
A bellows shape that can be expanded and contracted is provided in a section corresponding to the bending shape range of the first bending-molded protector, and an engagement receiving part is provided on the outside of the joint end surface at a position corresponding to the locking claw of the first bending-molding protector. and a second bellows-shaped molded protector arranged in pairs.

Further, among the wire harness protectors of this invention, the first bending-molded protector has substantially linear portions having a substantially U-shaped cross section and bent portions having an arcuate shape alternately arranged.

Furthermore, among the wire harness protectors of this invention, the second bellows-forming protector is one in which a substantially linear portion with a substantially U-shaped cross section and a bellows shape that can be freely expanded and contracted are arranged alternately. .
