DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness molding for storing a wire harness disposed on a vehicle body / equipment and maintaining and protecting the position of the wire harness disposed on a vehicle body or the like. It concerns the protector.

[0002]

2. Description of the Related Art A wire harness forming protector is shown in FIG.
3 reference), the side wall upper edge of the shaped protector body 2 of elongate U-shaped groove member penetrating accommodating the wire harness has a basic shape having a lid 3 which is hinged, this MOLDED protector
Hollow cylindrical attachment portion 31 protruding from the side wall of body 2
Is fitted and locked to the stud bolt 26 of the vehicle body 25, and is fixedly attached to the vehicle body 25, and the cover 3 after the storage of the wire harness 30 is locked in the covering position by the cover lock portion 32, and is stored. The arrangement posture of the wire harness 30 on the vehicle body 25 is adjusted and held, and the wire harness 30 is
It is designed for protection. Reference numeral 35 in the drawing denotes a claw piece that is locked to the lid lock portion 32.

[0003] A long and heavy wire harness 30 is provided.
The wire harness forming protector 1 in which
At the time of transportation to the fixed position on the vehicle body 25 or at the time of the disposition, the torsion or bending deformation is apt to occur due to the load resistance of the heavy wire harness 30.
From the intention of preventing disassembly and disposition on the vehicle body 25,
An attachment portion 31 and a lid lock portion 32 are disposed near the end of the molded protector body 2, and as shown in the drawing, both are located at the same position on the molded protector body 2, and overlap with each other. As shown in the figure, the frame 32 has a structure having excellent mechanical strength such as a rectangular frame.

[0004]

The wire harness forming protector 1 having the above-described conventional structure in which the lid lock portion 32 and the attachment portion 31 are disposed at the same position is provided with a lid lock projecting above the attachment portion 31. The punching hole 33 of the molding die of the part 32 is
It is necessary to provide between the attachment portion 31 and the molded protector body 2. Therefore, in order to prevent the mechanical strength of the attachment portion 31 from being reduced due to the presence of the mold release hole 33, it is necessary to take measures for reinforcing the reinforcing ribs 34 and the like. In addition to being a factor, the position of the attachment portion 31 shifts outward due to the presence of the die release hole 33, resulting in an increase in the shape of the molded protector main body 2. Therefore, it is required to strictly reduce the size to "small even if worn". There are difficulties that go against the technical requirements of wire harness systems.

Then, the lid lock portion 32 and the attachment portion 31
However, due to the separation structure, the molding die of the molding protector 1 becomes complicated, the molding die becomes expensive, and there is a possibility that the exposed type lid lock portion 32 comes into contact with the object and unlocks. The present invention is to provide a wire harness forming protector that solves the above-mentioned disadvantages of the prior art.

[0006]

The wire protector for a wire harness according to the present invention for solving the above technical problem is composed of a long protector body having a long U-shaped groove through which a wire harness is housed and a cover for the protector body. In a wire harness forming protector comprising a cover to be attached and attached to an attachment bolt of a vehicle body / equipment, a tongue at an edge of the cover is provided.
Hollow column fitted to the mounting bolt on the holding portion holding piece
In addition to providing a mounting attachment portion having a shape,
The mounting bolt is inserted into the main body to receive the mounting locking portion.
Providing a locking receiving portion having a locking step for locking and locking,
A plurality of attachment locking portions are obtained by slitting the peripheral wall of the hollow column.
And the elastic locking piece is
A second locking claw for retaining and locking to a step, and the mounting bolt
A first locking claw that locks and locks the hook;
Locking function of cover plate on the part and fixing to the mounting bolt
It has a function-coexisting structure. "

[0007]

According to the present invention, there is provided a molding harness for a wire harness according to the present invention having the above structure.
The protector is a fixing machine that attaches to the mounting bolts on the vehicle body and equipment.
Function and the locking function of the lid are
The conventional attachment fixing mechanism and lid locking mechanism.
, The overall structure of the molding protector is thinner.
Pulling is not required, and the die-cutting hole 33 of the conventional structure is unnecessary.
, So it is more compact.
