[Description of embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The wire harness protector of the present disclosure includes:
[1] A protector made of resin that accommodates a wire harness, including a bottom wall, and a first side wall and a second side wall provided on one side and the other side of the bottom wall, respectively, and facing the bottom wall. a gutter-shaped main body having an opening, an intermediate portion having an L-shaped cross section formed by the bottom wall and the second side wall is provided at an intermediate position in the extending direction of the main body; A notch is provided in at least one of a portion of the bottom wall on the side of the first side wall and a portion of the second side wall on the side of the opening.

When a wire harness having a small outer diameter is accommodated in the housing space of the main body of the protector, when the wire harness and the protector are wrapped with tape, a gap is created between the main body and the wire harness. For this reason, the binding force between the wire harness and the protector by the tape member tends to be weakened, and there is a possibility that the wire harness may be misaligned with respect to the protector.

In this regard, according to the above aspect, an intermediate portion having an L-shaped cross section is provided by the bottom wall and the second side wall, and the first side wall is not present in the intermediate portion. Therefore, if the wire harness and the protector are wrapped with tape at the intermediate portion, the binding force between the wire harness and the protector by the tape member may be weakened due to the gap created between the first side wall and the wire harness. It disappears. That is, while the wire harness is in close contact with the second side wall and the bottom wall, the second side wall, the bottom wall, and the wire harness can be strongly bound together by the tape member. Thereby, it is possible to suppress the wire harness from being misaligned with respect to the protector.

However, even in this case, the smaller the outer diameter of the wire harness is with respect to the housing space of the main body, the more difficult it is to fit the tape member tightly to the wire harness at the end of the bottom wall on the first side wall side and the second side wall. The opening end gets in the way and tends to weaken the binding force of the wire harness.

In this regard, according to the above aspect, the intermediate portion is provided with a cutout portion in which at least one of the bottom wall and the second side wall is cut out. That is, in the notch, at least one of the width of the bottom wall and the height of the second side wall is smaller than the other portions of the bottom wall or the second side wall. Therefore, the end of the bottom wall on the first side wall side and the end of the second side wall on the opening side are less likely to get in the way when the tape member is brought into close contact with the wire harness. Thereby, it is possible to increase the binding force between the wire harness and the protector, which has a small outer diameter relative to the housing space of the main body. Therefore, it is possible to wrap a plurality of types of wire harnesses having different outer diameters with tape at an intermediate position in the extending direction of the protector.

[2] Preferably, the cutout portion is provided in both a portion of the bottom wall on the first side wall side and a portion of the second side wall on the opening side of the main body.
According to the above aspect, in the notch, both the width of the bottom wall and the height of the second side wall are smaller than other parts of the bottom wall or the second side wall. Therefore, the end of the bottom wall on the first side wall side and the end of the second side wall on the opening side are less likely to get in the way when the tape member is brought into close contact with the wire harness. Thereby, it is possible to further increase the binding force between the wire harness and the protector for the wire harness having a small outer diameter relative to the accommodation space of the main body.

[3] It is preferable that the device has a cover that is connected to the main body via a hinge and opens and closes the opening, and that the cover is separated from the intermediate portion when the opening is open.
According to the above aspect, the intermediate portion where the wire harness is wrapped with tape can be protected by the cover. Furthermore, since the cover is separated from the intermediate portion when the opening is open, it is possible to prevent the cover from interfering with the tape member when wrapping tape around the notch in the intermediate portion. Therefore, tape winding can be easily performed.

[4] It is preferable that a mark is provided on the outer surface of the cover.
Since the first side wall is not provided, the wire harness can be drawn out to the outside using the opening formed in the intermediate portion. According to the above aspect, since the mark is provided on the outer surface of the cover, the length of the wire harness pulled out to the outside can be easily measured using the mark even when the opening is closed by the cover. be able to.

The wire harness with a protector of the present disclosure includes:
[5] The wire harness protector includes the wire harness protector, and a wire harness housed in the main body and wrapped with tape at the notch. According to this aspect, the same effect as any one of the wire harness protectors described above is achieved. Therefore, tape winding can be performed at an intermediate position in the extending direction of the protector.

[6] It is preferable that a branch line branched from the main line of the wire harness is drawn out of the protector through the intermediate portion.
According to the above aspect, since the first side wall is not provided, the branch line of the wire harness is drawn out to the outside using the opening formed in the intermediate portion. Therefore, the wire harness is wrapped with tape and bundled at the notch located on the proximal end side of the branch line. This eliminates the need to provide an extending portion on the main body for binding the branch line to the protector by wrapping with tape. Therefore, it is possible to suppress an increase in the size of the main body.

[Details of embodiments of the present disclosure]

Further, in a state where the opening 24 of the intermediate section 27 is opened by the second cover section 50, the second cover section 50 of the cover 30 is separated from the intermediate section 27.

As shown in FIG. 4, a mark 56 is provided protruding from the outer surface of the curved portion 51a of the second cover portion 50. As shown in FIG. The mark 56 has an isosceles triangular shape, and its apex points toward the first end in the extending direction Y.

In the protector 10 described above, the wire harness 60 is wrapped around the notches 28 and 29 by a tape member 70.
Next, the operation of this embodiment will be explained with reference to FIGS. 5 and 6.

FIG. 5 is a sectional view showing a state in which a wire harness 60A having a smaller outer diameter than the housing space of the main body 20 is wound with tape around the notches 28 and 29 of the protector 10. FIG. 6 is a sectional view showing a state in which a wire harness 60B having a large outer diameter relative to the accommodation space of the main body 20 is wound with tape around the notches 28 and 29 of the protector 10.

In a conventional protector, when a wire harness having a small outer diameter is accommodated in the housing space of the main body of the protector, when the wire harness and the protector are wrapped with tape, a gap is created between the main body and the wire harness. For this reason, the binding force between the wire harness and the protector by the tape member tends to be weakened, and there is a possibility that the wire harness may be misaligned with respect to the protector.

As shown in FIGS. 5 and 6, according to the above embodiment, an intermediate portion 27 having an L-shaped cross section is provided by the bottom wall 21 and the second side wall 23, and the intermediate portion 27 includes the first side wall 22 does not exist. For this reason, if the wire harnesses 60A, 60B and the protector 10 are wrapped with tape in the notches 28, 29 of the intermediate portion 27, the tape will be removed due to the gap created between the first side wall 22 and the wire harnesses 60A, 60B. The binding force between the wire harnesses 60A, 60B and the protector 10 due to the member 70 will not be weakened. That is, while the wire harnesses 60A, 60B are in close contact with the second side wall 23 and the bottom wall 21, the second side wall 23, the bottom wall 21, and the wire harnesses 60A, 60B can be strongly bound together by the tape member 70. . Thereby, it is possible to suppress the wire harnesses 60A, 60B from being misaligned with respect to the protector 10.

However, even in this case, the smaller the outer diameter of the wire harness 60 is with respect to the accommodation space of the main body 20, the more the edge of the bottom wall 21 on the first side wall 22 side is or the end of the second side wall 23 on the opening 24 side becomes a hindrance, and the binding force of the wire harness 60 tends to be weakened.

As shown in FIG. 5, according to the above embodiment, the intermediate portion 27 is provided with cutout portions 28 and 29 in which both the bottom wall 21 and the second side wall 23 are cut out. That is, in the notches 28 and 29, the width of the bottom wall 21 and the height of the second side wall 23 are smaller than other parts of the bottom wall 21 and the second side wall 23. Therefore, the end of the bottom wall 21 on the first side wall 22 side and the end of the second side wall 23 on the opening 24 side are less likely to get in the way when the tape member 70 is brought into close contact with the wire harness 60. Thereby, the binding force between the wire harness 60A and the protector 10 can be increased for the wire harness 60A having a small outer diameter with respect to the accommodation space of the main body 20.

Next, the effects of this embodiment will be explained.
(1) The protector 10 has a bottom wall 21, a first side wall 22 and a second side wall 23 provided on one side and the other side of the bottom wall 21, respectively, and is a gutter having an opening 24 facing the bottom wall 21. The main body 20 has a shape. An intermediate portion 27 having an L-shaped cross section formed by the bottom wall 21 and the second side wall 23 is provided at an intermediate position in the extending direction Y of the main body 20 . The intermediate portion 27 is provided with cutout portions 28 and 29 in which both a portion of the bottom wall 21 on the first side wall 22 side and a portion of the second side wall 23 on the opening 24 side are cut out.

According to the above aspect, by producing the above-described effects, it is possible to wrap a plurality of types of wire harnesses 60A and 60B having different outer diameters with tape at an intermediate position in the extending direction of the protector 10.

(2) The protector 10 includes a cover 30 that is connected to the main body 20 via a first hinge 44 and opens and closes the opening 24. The cover 30 is separated from the intermediate portion 27 with the opening 24 open.

According to the above aspect, the intermediate portion 27 on which the wire harness 60 is wrapped with tape can be protected by the cover 30.
Further, since the cover 30 is separated from the intermediate portion 27 when the opening 24 is open, the cover 30 is separated from the tape member 70 when wrapping tape around the notches 28 and 29 of the intermediate portion 27. can be prevented from interfering with Therefore, tape winding can be easily performed.

(3) A mark 56 is provided on the outer surface of the cover 30.
Since the first side wall 22 is not provided, the wire harness 60 can be drawn out to the outside using the opening 27a formed in the intermediate portion 27. According to the above aspect, since the mark 56 is provided on the outer surface of the cover 30, even when the opening 24 is closed by the cover 30, the length of the wire harness 60 pulled out to the outside is determined by the mark 56. can be easily measured.

(4) The wire harness with a protector includes the protector 10 and the wire harness 60 housed in the main body 20 and wrapped with tape.
According to the above aspect, the same effect as that of the protector 10 is achieved. Therefore, the tape can be wound at an intermediate position in the extending direction Y of the protector 10.

This embodiment can be modified and implemented as follows. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
- The shape of the mark 56 can also be changed to another shape such as an equilateral triangle.

- The mark 56 can also be omitted.
- The first hinge 44 of the first cover part 40 may be omitted, and the first cover part 40 and the second side wall 23 may be locked by the locking claw part 45 and the lock frame part 25. In this case, the cover 30 and the main body 20 can be formed separately.

- The first cover part 40 and the second cover part 50 can also be formed separately. In this case, the second hinge 54 can be omitted.
- The notch part 28 and the notch part 29 should just be a structure in which at least one is provided.

- The cover 30 can also be omitted.
- As shown in FIG. 7, the connecting portion 26 of the main body 20 can also be omitted. That is, a configuration in which the main line 63 of the wire harness 60 is routed along the extending direction Y of the main body 20, and the branch line 64 branched from the main line 63 is drawn out to the outside of the protector 10 through the opening 27a of the intermediate portion 27. It is also possible to do this.

According to the above aspect, since the first side wall 22 is not provided, the branch wire 64 of the wire harness 60 is drawn out using the opening 27a formed in the intermediate portion 27. Therefore, the wire harness 60 is wrapped with tape and bundled at the notches 28 and 29 located on the proximal end side of the branch line 64. This eliminates the need to provide the main body 20 with an extending portion for binding the branch line 64 to the protector 10 by wrapping with tape. Therefore, it is possible to suppress an increase in the size of the main body 20.
