Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness protector for use in an automobile, and more particularly, to a dimension between a position of a protector fixed to a vehicle body and a connection position of a tip connector of a wire harness penetrating the protector. However, it can be shared without being a separate part.

[0002]

2. Description of the Related Art Conventionally, wiring harnesses installed in automobiles have been used for the purpose of protecting the wiring harness from external interference materials and restricting the wiring line of the wiring harness.
A protector, which is a resin molded product, is provided, and a wire harness is passed through the protector. Normally, as shown in FIG. 5, the protector 1 has fixing pieces 1c projecting from bottom walls 1b at both ends of a main body 1a for accommodating a gutter-shaped wire harness, and the wire harness W / H is attached to the fixing pieces 1c. The tape 2 is wound and fixed.

The protector 1 is fixed to a vehicle body, while a connector 3 connected to a tip of a wire harness W / H is fitted and connected to a mating connector arranged at a predetermined position. Therefore, if the dimensions of the protector 1 fixed to the vehicle body and the connector 3 are different, that is, the dimension A (150 mm) as shown in FIG. 6A and the dimension B (B as shown in FIG. 6B) 200 mm), the dimension from the fixed position of the protector 1 to the tip connector 3 is A
It is necessary to provide two types of part numbers (parts), dimensions and B dimensions.

[0004] In order to solve this kind of problem, a conventional Japanese Utility Model
No. 60419, as shown in FIGS.
An elastic holding piece 4b is formed by cutting and raising the side wall 4a of the main body of the protector 4, and a line of sight W / H-2 branched from a wire harness trunk line W / H-1 penetrating the main body depending on a bending position of the elastic holding piece 4b. The one that adjusts the take-out position from the protector has been proposed.

[0005]

The protector shown in FIG. 7 draws a line of sight branching from a main line penetrating the main body from the side wall of the protector. Is not available. In addition, since a restoring force always acts on the elastic holding piece 4b, there is also a problem that a load from the elastic holding piece 4b acts on the branch line fixed to the elastic holding piece 4b by tape winding.

[0006] Therefore, the body of the protector penetrates,
If the length of the wire harness to which the tape is wound and fixed by the fixing piece is different, as shown in FIG. 6, the wire harness must be manufactured as a separate product number, which increases the number of parts and increases the cost. In addition, there is a problem that these part numbers must be properly used, which requires a lot of management.

[0007] The present invention has been made in view of the above-mentioned problems, and it is desirable that the protector fixed to the vehicle body and the connecting position of the tip end of the wire harness penetrating the protector and fixed by the fixing piece change. It is an object of the present invention to be able to share a single product number.

[0008]

In order to solve the above-mentioned problems, the present invention relates to a wire harness protector made of a resin molded product and fixed to a vehicle body with the wire harness penetrating therethrough. The end of the bottom wall of the main body to be pierced and the fixed piece for winding and fixing the wire harness by tape are connected by a pair of left and right narrow flexible pieces, and the fixed piece is moved by expansion and contraction of the flexible piece. There is provided a wire harness protector characterized in that the distance from the main body is adjustable.

When the fixing piece is connected to the main body through a pair of flexible pieces as described above, the fixing piece can be moved by expanding and contracting the flexible piece, and the fixing position of the wire harness to the protector is adjusted. As a result, the length of the wire harness drawn from the protector can be adjusted.

[0010] A connector is connected to the tip of the wire harness that is fixedly wound on the fixed piece with a tape. When the dimensions of the connector arrangement position and the fixing position of the protector are different, the flexible piece is expanded and contracted to expand and contract. It corresponds to the difference in dimensions.

That is, when the dimension between the fixing position of the protector and the connector connecting position at the tip of the wire harness is long, the flexible piece is in a straightened state. On the other hand, when the dimension between the fixing position of the protector and the connector connection position at the tip of the wire harness is short, the flexible piece shrinks to correspond to the dimension. When the flexible piece shrinks, the wire harness in the protector main body is loosened, but if the amount of the wire harness is larger than the amount of the wire harness that penetrates the volume of the protector main body, the slack in the wire harness is absorbed. be able to.

As described above, since the fixed pieces of the protector are connected to each other by the flexible pieces and are movable, the fixed position of the protector and the connection position of the wire harness that passes through the protector and is fixed by the fixed pieces. Even if the dimensions between them are different,
The movement of the fixed piece can absorb the difference in dimensions, and can be shared by one product number.
