DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness which is used for inserting and storing a wire bundle of a wire harness, arranging the wire bundle on a vehicle body / equipment, and fixing and arranging the arrangement posture of the wire harness. The present invention relates to a molding protector for use.

[0002]

2. Description of the Related Art A molded protector for a wire harness has a U-shaped groove-shaped molded protector body for accommodating a bundle of electric wires, and a lid body for closing an opening of the molded protector body. As shown in FIG. 3, a reinforcing rib 10 is provided on the inner periphery of the groove of the molded protector body 1 so as to protrude in the transverse direction of the groove. A structure in which a separate lid 2 or a lid 2 connected to the molded protector main body 1 via a hinge portion 4 is closed and locked is used.

[0003]

SUMMARY OF THE INVENTION A molded protector for a wire harness has a function of accommodating a wire bundle of a heavy and long wire harness, and preparing and holding a complicated three-dimensional arrangement shape of a vehicle body and equipment. However, since the car body to which the molded protector is attached has only a narrow allowable space, and is in an installation environment where other devices and the like are present in the periphery, the installation route is severely restricted, In the region where the forming protector is set, the wire harness may be forcibly bent to form a route for the arrangement, and the rigidity of the forming protector that can withstand the elastic reaction force of the wire harness due to the forcible bending is required.

However, the wire protector for a wire harness having the conventional structure described above is a combination of a protector body 1 having a reinforcing rib 10 and a cover body 2, and each of which bears the above-mentioned deformation force individually. 1 and the lid 2 have a basic structure with only the total rigidity, and the reinforcing ribs 10 also satisfy the required rigidity under the miniaturization-oriented base where the wire harness system is strongly required to be "small even if worn". Since it is not possible to set a sufficient shape,
"Torsion deformation" due to lack of rigidity when installed on the car body
Or "bending", and comes into contact with peripheral devices and members, causing various obstacles.

[0005] The present invention provides a wire harness forming protector that solves the above-mentioned disadvantages of the prior art.

[0006]

A molded protector for a wire harness according to the present invention, which solves the above technical problems, includes a molded protector body of a U-shaped groove body for inserting and storing a wire bundle of a wire harness, and a molded protector body. In a molded protector for a wire harness comprising a separate lid body, a female reinforcing rib having a fitting groove formed in a vertical direction of the side wall is integrally formed inside the side wall of the molded protector body. And a structure in which a male reinforcing rib is provided on the inner side of the lid so that a fitting column fitted in the fitting groove is protruded from a flange piece in a posture of covering the molded protector body.

[0007]

Since the molded protector for a wire harness of the present invention having the above-described structure has the female reinforcing ribs of the molded protector body and the male reinforcing ribs of the lid, the lid is covered. In the state, the molded protector body and lid are
It is a combined structure of a substantially integral body, and possesses synergistic rigidity of the molded protector body and the lid against torsional and bending external forces, and the cross-sectional secondary pole moment and the cross-sectional secondary moment of the wire harness molded protector This is particularly improved over the conventional structure.

Therefore, if the above-mentioned female and male reinforcing ribs are provided at required positions at an appropriate pitch, even if the above-mentioned strong "torsional stress" and "bending stress" are received, they are countered. The obtained "torsional rigidity" and "bending rigidity" are provided, and the required shape of the wire harness forming protector can be maintained without increasing the size.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. First, with reference to FIG. 1 showing a first embodiment of the present invention, a molded protector main body 1 of a U-shaped groove body through which an electric wire bundle (not shown) of a wire harness is inserted and stored, and the molded protector main body 1 is covered. In the wire harness forming protector including the separate lid 2, a side wall 3A
Inside the inner wall 3B, a female reinforcing rib 6 extending from the upper end to the lower end of the side walls 3A and 3B, and having a fitting groove 5 formed in the center in the vertical direction, is integrally ridged. Inside the
A male reinforcing rib 7 having a T-shaped cross section is formed by projecting a fitting column 8 fitted into the fitting groove 5 at the center of the flange piece 9 and integrally rising therefrom.

When the cover 2 is covered with the molded protector body 1 (see FIGS. 1B and 1C), the fitting columns 8 of the male reinforcing ribs 7 are fitted with the fitting grooves of the female reinforcing ribs 6. 5, the flange piece 9 is located at the front end of the female reinforcing rib 6, and the female / male reinforcing ribs 6, 7 are joined to form a structure that functions to improve the rigidity of the wire harness forming protector. Has become. In addition, the flange piece 9 of the male reinforcing rib 7 of this embodiment has a triangular shape having an apex at a tip position of the fitting column 8.

In the embodiment shown in FIG. 1, since the female and male reinforcing ribs 6 and 7 are connected in the covering position of the lid 2, even if a strong "torsion force" or "bending force" is received. The molded protector main body 1 and the lid 2 can exert the above-mentioned action by resisting them substantially as an integral body.
Then, deformation in the vehicle body arrangement state is prevented, and interference trouble with other members and peripheral devices due to the deformation can be eliminated.

The female and male reinforcing ribs 6 in the present invention
7 is not limited to the above-described embodiment, and as illustrated in FIG. 2, the male reinforcing rib 7 is formed in an L shape, the flange piece 9 is formed in a rectangular shape, or the female reinforcing rib 6 is shortened. To half size.

[0013]

As described above, the wire harness forming protector of the present invention prevents deformation in the state of being installed on the vehicle body and equipment, eliminates contact trouble with other members due to deformation, and forms the wire harness. In addition to stabilizing the function of the protector, the function stabilization does not increase the shape of the molded protector, and has the effect of meeting the demand in the field of miniaturization of the wire harness system.
