Description

The present invention relates to a protector that covers at least a portion of a wire harness.

Generally, protectors and corrugates are known as exterior products that protect wire harnesses.
The protector includes a groove-shaped protector body having an opening and a cover body that closes the opening in the protector body, and is made of a non-flexible material. Therefore, the protector has a wire harness protection function and a wire harness route regulation function.

A corrugate is a flexible member that has an uneven outer circumferential shape in which the circumferential unevenness continues in the axial direction, and into which a wire harness is inserted. Therefore, corrugated wire has a wire harness protection function.

Generally, the wiring route of a long wire harness includes a portion that is only protected and a portion that is not only protected but also has route regulation. Therefore, the parts that only protect the wire harness are covered with corrugated metal, and the parts that not only protect but also regulate the wiring are covered with protectors. Then, a corrugate is inserted into the protector from its longitudinal end to connect the protector so that the wire harness is not exposed between them.

For example, Patent Document 1 discloses one of the structures of the connecting part between the corrugate and the protector, in which the corrugate that is sheathed on the wire harness is arranged in a U-shaped part of the protector body, and a regulating rib is integrally formed on the protector body. It is disclosed that the corrugate is fitted into an outer circumferential recess of a corrugate having an uneven outer circumferential shape to restrict extraction of the corrugate in the axial direction.

However, in the conventional structure disclosed in Patent Document 1, before the opening of the protector body is closed by the cover body, each connection end of the wire harness is connected to, for example, an in-vehicle electrical component provided in the vehicle. When performing this work, the wire harness and the corrugated wire were displaced so as to float toward the opening side of the protector main body, and there was a risk that the corrugated gate would fall off during the work.

In addition, since the elastic piece 38 is disposed near the end of the protector body 30 in the corrugated connection portion 35 (see FIGS. 2 and 3), the corrugation 20 is formed to be long in the axial direction from the end of the protector body 30. Even if the corrugate 20 has a short axial length from the end of the protector main body 30, the corrugate 20 can be temporarily fixed by the elastic piece 38.

Furthermore, since the elastic piece 38 is in contact with the outer circumferential convex part 22 of the corrugated gate 20 having an uneven outer circumferential shape (see FIGS. 2 and 5), the elastic piece 38 is stably brought into contact with the outer circumferential convex part 22 of the corrugated gate 20. can be brought into contact.

Furthermore, since the elastic piece 38 has a structure in which the thickness gradually becomes thinner toward the tip (see FIGS. 6 to 8), the elastic piece 38 is formed in a tapered shape and has excellent elastic deformability. can be easily inserted into the interior 34 of the protector body 30 from the opening 31 side of the protector body 30.

In addition, since the elastic piece 38 is in an inclined attitude toward the insertion direction α of the corrugate 20 (see FIGS. 6 to 8), the inclined attitude of the elastic piece 38 allows the corrugate 20 to be aligned with the opening 31 of the protector body 30. The corrugate 20 can be easily inserted into the interior 34 of the protector body 30 from the side, and once inserted into the interior 34 of the protector main body 30, the elastic piece 38 in the inclined position can reliably prevent the corrugate 20 from slipping out.
In other words, the inclined posture of the elastic piece 38 makes it possible to improve both the insertability of the corrugated gate 20 and the improved ability to prevent the corrugated gate 20 from slipping out.

Further, since the corrugate connecting portion 35 is provided with a regulating rib 37 that is fitted into the outer circumferential recess 21 of the corrugate 20 having an uneven outer circumferential shape and regulates the extraction of the corrugate 20 in the axial direction (Figs. 2 to 4, 6), the regulating rib 37 can prevent the corrugate 20 from coming off in the axial direction.

Specifically, when the corrugate 20 is inserted into the inside 34 of the protector body 30 from the opening 31 side of the protector body 30, its movement in the escape direction β is regulated by the elastic piece 38, and the movement of the corrugate 20 in the axial direction is regulated. Since it is restricted by the ribs 37, the temporary fixation of the corrugated gate 20 is ensured, and the workability of wiring the wire harness is further improved.

Furthermore, the corrugated connecting portion 35 is provided with a plurality of regulating ribs 37 at predetermined intervals in the axial direction, and the elastic pieces 38 are arranged between the plurality of regulating ribs 37 (see FIGS. 2 to 4). ), the regulating ribs 37 are located in the outer circumferential concave portion 21 of the corrugated gate 20, and the spaces between the plurality of regulating ribs 37 are located in the outer circumferential convex portion 22 of the corrugated gate 20, so the elastic piece 38 is disposed between the regulating ribs 37. The elastic piece 38 is located on the outer peripheral convex portion 22 of the corrugated gate 20. Therefore, the elastic piece 38 can be appropriately brought into contact with the outer circumferential convex portion 22 of the corrugated gate 20, and the escape of the corrugated gate 20 can be stably prevented.

Furthermore, the elastic piece 38 is disposed between the regulating rib 37A closest to the end of the protector body 30 among the plurality of regulating ribs 37 and the regulating rib 37B adjacent to the regulating rib 37A (see FIG. 3), the elastic piece 38 can further reliably prevent the corrugate 20 from escaping.

In addition, a confirmation window 39 that communicates between the inside 34 of the protector body 30 and the outside is provided below the elastic piece 38 in the corrugated connecting portion 35. The state of regulation of the corrugated gate 20 by the piece 38 can be visually confirmed.

In addition, since a cover body 40 is provided that closes the opening 31 of the protector body 30 formed in a groove shape (see FIGS. 8 and 9), by closing the opening 31 of the protector body 30 with the cover body 40, the corrugated 20 can be fixed more reliably, and the escape of the corrugated gate 20 can be prevented.
