Description

  The present invention relates to a protector for a wire harness, and in particular, facilitates an attaching operation to a vehicle body panel.

Conventionally, wire harnesses that are routed in automobiles have a protector made of a resin molded product on the exterior, protecting the wire harness from external interference materials, and restricting the wiring route of the wire harness. The protector is fixed to the vehicle body panel.
The protector is fixed to the vehicle body panel by inserting and locking a clip provided on the protector into the through hole of the vehicle body panel. However, since the clip is provided on the bottom surface side of the protector and is difficult to see, there is a problem that it is difficult to align the clip and the through hole of the vehicle body panel, and the workability of attaching the protector to the vehicle body panel is poor.

  In order to solve the above problem, Japanese Utility Model Laid-Open No. 63-173864 (Patent Document 1) provides a protector 1 shown in FIG. 5. The protector 1 is provided on the bottom surface side on a visible surface. A protrusion 3 is provided at a position facing the clip 2, and the alignment of the clip 2 and the through hole 4 a of the vehicle body panel 4 is facilitated by using the protrusion 3 as a mark.

  However, in Patent Document 1, when the clip 2 is pushed into the through hole 4a in a state where the clip 2 of the protector 1 and the through hole 4a of the vehicle body panel 4 are aligned, the pushed wall portion is not pressed. There is a problem that the pressing force is not easily transmitted to the clip 2 because the side wall is bent slightly inward or the side wall bulges outward, and the clip 2 cannot be easily pushed into the through hole 4a.

Japanese Utility Model Publication No. 63-173864

  The present invention has been made in view of the above problems, and it is an object to facilitate not only the positioning of the clip of the protector and the through hole of the vehicle body panel but also the pushing operation of the clip into the through hole. It is said.

In order to solve the above-mentioned problem, the present invention includes a hook-shaped main body that passes through a wire harness routed in an automobile,
A cover for closing the upper surface opening of the body;
A clip that is inserted and locked into the through hole of the vehicle body panel protrudes on the outer surface of the bottom wall of the main body, while the cover can be flexed by partially cutting the periphery at a position facing the clip of the main body. Provided is a protector for a wire harness, characterized in that a pressing flexure piece is provided.

According to the protector for a wire harness of the present invention, the cover that can be seen by an operator when the protector is attached to the vehicle body panel is provided with a bent piece at a position facing the clip. The positioning of the clip and the through hole of the vehicle body panel can be facilitated.
When the clip is pushed into the through-hole, when the pressing bending piece is pressed, the bending piece bent inward comes into contact with the wire harness inserted into the protector. Thereby, the pressing force which pushed the bending piece is transmitted to the clip on the bottom wall side through the wire harness, and the clip can be easily pushed into the through hole of the vehicle body panel.

It is preferable that ribs protrude from the inner surface of the bending piece, or that the bending piece is thick on the inner surface side.
According to the above configuration, when the bending piece is pushed when the clip is pushed into the through hole, the rib tip of the bending piece bent inward or the inner surface of the bending piece easily comes into contact with the wire harness inserted into the protector. The clip can be easily pushed into the through hole of the vehicle body panel.

It is preferable that the notch provided around the bent piece is U-shaped.
According to the said structure, even if the front-end | tip of a bending piece becomes circular arc shape and the front-end | tip of a bending piece contacts the wire harness inserted in the protector, it can prevent that a wire harness is damaged.

Moreover, it is preferable that the notch provided around the bent piece has a narrow width.
According to the said structure, foreign materials, such as dust, and water cannot enter easily from a notch, and the performance of a protector is not reduced.

It is preferable that an uneven portion is provided on the outer surface of the bending piece.
According to the said structure, the slipping when pressing a bending piece can be prevented by the uneven | corrugated | grooved part provided in the outer surface of the bending piece.
Further, the position of the flexure piece can be more easily recognized by the uneven portion.

A columnar protrusion is provided on the inner surface of the bottom wall of the main body at a position facing the clip, and when the bent piece of the cover is bent inward, it protrudes into the inner surface of the bent piece or the inner surface of the bent piece. It is good also as a structure which the front-end | tip of the provided rib contact | abuts the front-end | tip of the said columnar protrusion.
According to the above configuration, when the bending piece is pressed, the rib tip of the bending piece bent inward or the inner surface of the bending piece comes into contact with the columnar protrusion, not the wire harness inserted into the protector. Since the columnar protrusion is provided integrally with the clip through the bottom wall, the pressing force of pressing the bending piece is easily transmitted to the clip through the columnar protrusion, and the clip is more easily attached to the through hole of the vehicle body panel. Can be pushed into.

As described above, according to the present invention, since the bending piece is provided at the position facing the clip on the cover that is visible when the protector is attached to the vehicle body panel, the clip and the vehicle body are marked with the bending piece. The alignment of the through hole of the panel can be facilitated.
Further, when the bending piece is pushed when the clip is pushed into the through hole, the bending piece bent inward comes into contact with the wire harness inserted into the protector or the columnar protrusion protruding from the inner surface of the bottom wall of the main body. Thereby, the pressing force which pushed the bending piece is transmitted to the clip, and the clip can be easily pushed into the through hole of the vehicle body panel.
