Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness clamp guide, and more particularly to a clamp guide for positioning and attaching a wire harness consisting of a large number of electric wires to a clamp provided on a vehicle body panel of an automobile. Even if the outer diameter of the wire harness changes, the wire harness is closely fitted to the wire harness so that the wire harness can be immovably fixed.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, when a wire harness W / H composed of a large number of electric wires is held by an annular clamp 1 attached to a vehicle body panel of an automobile, the outer circumference of the wire harness W / H is The clamp guide 2 for positioning and holding is attached to the surface, and the clamp 1 is wound around the outer circumference of the clamp guide 2 to route the wire harness W / H inside the automobile.

The clamp guide 2 is made of resin, and as shown in FIG. 8, a pair of semi-annular members 2c and 2d is divided into half by splitting a cylindrical member having guide flanges 2a and 2b at both ends. One end is integrally molded in a state in which one end is connected by a thin hinge 2e.

The clamp guide 2 is connected to the wire harness W.
9A, the tape 3 is wound around the clamp guide mounting position of the wire harness W / H a required number of times to attach the wire harness W / H to the wire harness W / H.
The outer diameter of H is set to be substantially the same as or slightly larger than the inner diameter of the clamp guide 2. Then, the other end of the pair of semi-annular members 2c, 2d is opened with the hinge 2e as a fulcrum, and is fitted on the outer peripheral surface of the wire harness W / H as shown in FIG. 9 (B). H is pressed and held in the clamp guide 2, and the wire harness W /
It is fixed so that H does not move. In this state, the clamp 1 formed by annularly forming a plate material is spread and wound around the outer peripheral surface between the collar portions 2a and 2b of the clamp guide 2, and the tip of the clamp 1 is placed near the winding start point around the clamp guide 2. The wire harness W / H is positioned and arranged on the vehicle body panel by fixing with a screw.

[0005]

As described above, since the conventional clamp guide 2 has a constant inner diameter, when the outer diameter of the attachment position of the wire harness W / H is small, the wire inside the clamp guide 2 is small. The harness W / H moves and the mounting position is displaced. On the other hand, when the outer diameter of the wire harness W / H is large, the clamp guide 2 cannot be attached to the outer circumference of the wire harness W / H. Therefore,
A plurality of types of clamp guides having different inner diameters are provided, and the tape 3 is wound around the clamp guide mounting position to adjust the outer diameter of the wire harness to correspond to the inner diameter of the clamp guide 2 as described above. However, since tape winding is a manual operation, variations easily occur.

Therefore, the tape winding operation must be performed while confirming the number of times the tape 3 is wound using a check gauge so that the outer diameter of the mounting position accurately corresponds to the inner diameter of the clamp guide 2. The workability is very poor. Further, since a plurality of types of clamp guides 2 having different inner diameters are required, the number of parts is increased, which causes a problem of high cost.

The present invention has been made in view of the above problems, and in a clamp guide for positioning and holding a wire harness consisting of a large number of electric wires in a clamp provided on a vehicle body panel, the outer diameter of the wire harness is It is an object of the present invention to provide a clamp guide that can easily hold a wire harness in a fixed state even if it changes.

[0008]

In order to achieve the above object, the present invention provides a clamp guide for positioning and mounting a vehicle body fixing clamp on a wire harness according to claim 1, which is flexible. And a trapezoidal flat plate portion formed of a material, and a pair of guide flanges projecting along both non-parallel side edges of the flat plate portion. These flanges are orthogonal to the axial direction of the wire harness. The flat part is wound around the wire harness as the direction of rotation, the flanges on both sides in the narrow width direction are positioned inside the flanges on both sides in the wide width direction, and in this state, the locking portions provided on the wide width side and the narrow width side are selected. The clamp guide for a wire harness is characterized in that the diameter of the flat plate portion wound around the wire harness can be adjusted according to the diameter of the wire harness.

According to the above clamp guide, since the flat plate portion is wound around the wire harness, it is possible to obtain a required diameter corresponding to the outer diameter of the wire harness. Also, even if the winding angle of the flat plate part is changed according to the outer diameter of the wire harness, the flat plate part has a trapezoidal shape, so both narrow side rib parts should be along the inner surface of the wide side flange parts. In addition, since the locking portions that selectively lock the brim portions that are in contact with each other are provided, the winding of the flat plate portion can be fixed in a state in which the flat portions are closely attached. In this way, since the inner diameter of the cylindrical member formed by winding the flat plate portion can be easily adjusted, the clamp guide can be commonly used for various wire harnesses having different outer diameters.

According to a second aspect of the present invention, the flange portions on both sides of the wide width are
A plurality of locking holes are arranged side by side from one side on the wide side toward the narrow side, while a locking projection is provided at the tip of both side flanges on the narrow side, and the locking projection is provided in any one of the above locking holes. It is configured to be selected and locked.

According to a third aspect of the present invention, a band having a large number of locking holes arranged side by side is projected from the narrow end of the flat plate portion, while a locking projection is projected on the wide side outer surface of the flat plate portion. The locking projection is selected and locked in any of the locking holes.

[0012] As in the second and third aspects, since the locking portion that selectively locks is composed of the plurality of locking holes and the locking projections, the locking portion is engaged with the locking hole at a predetermined position. By locking the stop projection, the inner diameter of the cylindrical member formed by the flat plate portion can be adjusted, and the locked state can be reliably retained.

It is preferable that the surface of the flat plate portion, which is opposite to the projecting side of the flange portion and is in contact with the wire harness, is subjected to a pear-skin treatment for slip prevention. (Claim 4) When the surface of the flat plate portion in contact with the wire harness is subjected to the matte finish for slip prevention, the wire harness becomes difficult to move with respect to the clamp guide.
