Description

  The present invention relates to a routing structure for a sliding door harness, and more particularly, to appropriately control a bending angle of a harness routed between a vehicle body and a sliding door.

Conventionally, a harness is bridged between a vehicle body and a sliding door in order to constantly supply power to electrical components on the sliding door side. As this type of routing structure, for example, as shown in FIG. 10, a wire harness W / H is inserted into a caterpillar-shaped cable guide 2 in which a plurality of link members 1 are linearly connected, and this is connected to a vehicle body 3. A structure in which an S-shaped cable is arranged between the sliding door 4 and the sliding door 4 has been proposed (see Japanese Patent Application Laid-Open No. 2004-40863).
The caterpillar-shaped cable guide 2 has a function of preventing the interference with peripheral members by controlling the bending of the wire harness W / H and taking the clearance with the vehicle body 3 in addition to the function of protecting the electric wire. Yes.

On the other hand, the caterpillar-shaped cable guide 2 is expensive because the number of parts of the link member 1 is large, and the wire harness W / H inserted through the cable guide 2 is exposed from the gap between the link members 1. It is necessary to further sheath the cable guide 2 with the tube body 5 as shown in FIG. 11 to prevent the wire harness from being exposed.
Some sliding doors operate while changing the angle in the vertical direction perpendicular to the sliding direction. To cope with such vertical movement, a vertical movable mechanism as shown in FIG. 12 is used. Furthermore, it is necessary to provide (refer Unexamined-Japanese-Patent No. 2004-40862).
That is, it is necessary to interpose the connecting member 7 pivotally supported in the vertical direction (arrow T direction) between the fixing member 6 fixed to the vehicle body 3 and one end of the cable guide 2. There is a problem that the number of parts increases and the structure becomes complicated.

On the other hand, instead of the cable guide, if a corrugated tube in which annular crests and troughs are alternately provided in the axial direction is used as a harness exterior material, the cost can be suppressed and the harness is not exposed to the outside. Since the change in the vertical direction of the sliding door can be absorbed by the flexibility of the corrugated tube, the harness can smoothly follow the movement of the sliding door.
However, since the corrugated tube is flexible, it is difficult to control the trajectory in the follow-up operation, and the harness sheathed with the corrugated tube may interfere with peripheral members.

JP 2004-40863 A JP 2004-40862 A

  The present invention has been made in view of the above problems, and has a simple structure that allows a harness spanned between a vehicle body and a sliding door to smoothly follow the movement of the sliding door, and the bending angle of the harness in the following operation. It is an object to prevent interference between the harness and the peripheral member by controlling the above.

In order to solve the above problems, the present invention is provided with an exterior material for guiding and protecting a harness routed between the vehicle body and the sliding door,
The exterior material consists of a corrugated tube attached to the entire length of the harness in the area of the crossover wiring, and a guide protector for bending regulation partially covered on the corrugated tube,
The guide protector includes a rectangular cylindrical link made of a plurality of rigid materials, has an uneven engagement portion that fits with the unevenness of the corrugated tube on the inner surface of each link, and has a pair of opposing side lengths A sliding door characterized in that a protrusion is provided at one end in the direction and a groove that opens in a V shape is provided at the other end, and the protrusion is fitted and connected to the groove so as to be bent at a predetermined angle between adjacent links. The harness wiring structure is provided.

As described above, by attaching the corrugated tube to the entire length of the harness in the cross wiring area, the cost can be reduced as compared with the conventional structure in which the caterpillar-shaped cable guide is attached to the entire length of the harness. Because the flexibility can also absorb changes in the vertical direction of the slide door, the harness can smoothly follow the movement of the slide door without providing a separate vertical moving mechanism.
Further, since the harness is not exposed to the outside by attaching a corrugated tube to the entire length of the harness, the exterior material (which is necessary to prevent the harness from being exposed from the gap when the cable guide is attached) The tube body) is not necessary, and the number of parts can be reduced and the structure can be simplified.

  Moreover, according to the said structure, since the corrugated tube attached to the full length of the harness can be partially covered with the guide protector for bending control, interference with peripheral members in the corrugated tube is likely to occur. The bending restricting guide protector can be attached to a part such as a part where the bending angle of the harness needs to be restricted. Therefore, the bending angle of the harness can be effectively controlled without greatly increasing the number of parts, and interference between the harness and the peripheral member can be prevented.

Specifically, the guide protector formed by connecting a plurality of links is provided with a concave and convex engaging portion that fits with the concave and convex portions of the corrugated tube on the inner surface of each link. The guide protector can be fixed at the required position of the corrugated tube simply by fitting the concave and convex portions of the corrugated tube at the required position.
It is preferable that the uneven locking portion is formed in an annular shape and is provided continuously in the length direction of the link.

  Further, as described above, a protrusion is provided at one end in the length direction of a pair of opposing sides of each link forming the guide protector, and a groove opening in a V shape is provided at the other end, so that the protrusion of the adjacent link is provided. Is configured to be fitted to the groove so as to be bent at a predetermined angle, the bending angle between the linked links, and further the bending angle of the harness in the corrugated tube can be regulated within the range of the predetermined angle. That is, from the state where one side of the protrusion of the adjacent link is brought into contact with and fitted to one side of the groove that opens in a V shape, the other side of the protrusion is moved to the other side of the groove. The bending angle of the internal harness is regulated by setting the movable range of the link up to the state of being brought into contact with the side and fitted.

  The shape of the protrusion is not particularly limited as long as the protrusion can be fitted in a groove that opens in a V shape so that the protrusion can be bent at a predetermined angle. For example, the protrusion is trapezoidal, and the trapezoidal protrusion It is preferable that the bending (rotation) of the protrusion is regulated by abutting the side of the groove with the side of the groove opening in a V shape.

  In addition, as the bending angle between the links regulated by the structure, from the viewpoint of preventing interference with peripheral members and the durability of the harness, with respect to the axis of the link when the links are connected in a straight line, It is preferable that the angle formed by the axis of the link when the linked link is bent to the maximum is about 25 to 35 °.

  The pair of sides orthogonal to the pair of sides is provided with a notch on one end side in the length direction of the link and a protruding portion on the other end side, and the protruding portion protrudes into the notch between adjacent links. It is preferable that they are overlapped at the end portions in the length direction and cannot be bent in the direction orthogonal to the bending direction.

  As described above, in a pair of sides orthogonal to the pair of opposite sides of the link, a notch is provided on one end side in the length direction of the link and a protrusion is provided on the other end side, and the notch is provided between adjacent links. With the configuration in which the protruding portions are projected and overlapped, it is impossible to bend in the overlapping direction, and the bending between the links can be limited only to the bending direction described above.

  The amount of protrusion of the protrusion protruding into the notch cannot be limited because it varies depending on the bending angle between the links. For example, in a link linked in a straight line, the protrusion is in the link length direction. It is preferable to protrude and overlap to a position of about 90% of the total length of the notches. The total length of the notch is preferably about 25% of the total length of the link including the protrusion, for example.

  The harness is routed horizontally between the vehicle body and the sliding door, and the projections and grooves of the links of the guide protector are provided on the upper and lower sides, the links can be bent in the horizontal direction, and in the vertical direction. It is preferable that bending is impossible.

When a harness is routed horizontally between the vehicle body and the slide door, the harness follows the movement of the slide door while bending in the horizontal direction. However, when the harness is sheathed with a corrugated tube, the harness is liable to sag due to the flexibility of the corrugated tube or the bending angle in the horizontal direction is too large, and the harness is likely to interfere with peripheral members.
Therefore, as described above, the protrusions and grooves of each link of the guide protector are provided on the upper and lower sides so that the links can be bent in the horizontal direction and not in the vertical direction, thereby allowing the corrugated tube to hang down. A smooth follow-up operation to the sliding door is possible while suppressing the horizontal bending angle appropriately.

Further, fixing the mounting bracket to the vehicle body and the sliding door, respectively, providing the mounting bracket with a concave and convex engaging portion that fits with the concave and convex of the corrugated tube, fixing the corrugated tube directly to the mounting bracket, and
It is preferable that the guide protector is externally mounted on a corrugated tube in the transition wiring portion adjacent to the mounting bracket on the vehicle body side and the sliding door side.

  As mentioned above, because the flexible corrugated tube is attached to the entire length of the harness in the crossover area, the corrugated tube is fitted to the mounting bracket that is fixed to the vehicle body and the sliding door without interposing a rotating mechanism. By simply fixing directly, the harness can smoothly follow the movement of the sliding door. That is, since it is not necessary to provide a rotation mechanism or the like on the mounting bracket, the structure can be further simplified.

  The mounting bracket is provided with a fan-shaped opening through which the harness with the corrugated tube attached is drawn into the mounting bracket, and the fan-shaped region of the opening is fixed to the concave and convex engaging portion of the mounting bracket. It becomes the movable range of the tube. That is, both sides of the fan-shaped opening play a role of restricting the bending of the corrugated tube, and the angle formed by both sides of the opening is about 90 to 120 ° in the mounting bracket on the vehicle body side, and the mounting on the sliding door side In the bracket, the angle is preferably about 100 to 150 °.

In addition, the crossover routing part close to the mounting brackets on the vehicle body side and sliding door side is particularly susceptible to large bending, and as a result, the harness interferes with peripheral members such as tire houses and is damaged by excessive bending. There are many cases. Therefore, as described above, the bending angle of the portion that is easily subjected to large bending is controlled by covering the corrugated tube of the cross wiring portion adjacent to the mounting bracket on the vehicle body side and the sliding door side with the guide protector. Therefore, interference between the harness and the peripheral member can be effectively prevented.
The guide protector may be provided continuously on the crossing portion adjacent to the mounting bracket, or may be provided separately.

  It is preferable that the corrugated tube that covers the entire length of the cross wiring region has an elliptical cross section in at least an intermediate region that does not cover the guide protector.

As described above, by making the cross-sectional shape of the corrugated tube in the intermediate region where at least the guide protector is not packaged into an ellipse, the straightness of the harness can be improved, and a smooth follow-up operation can be performed in a small space.
Further, it is more preferable that the cross-sectional shape of the corrugated tube not only in the intermediate region but also in the region covered with the guide protector is elliptical because rotation of the corrugated tube in the link can be prevented.

  Further, at least the corrugated tube in the region covered by the guide protector has a circular cross section, and one rib extending in the axial direction projects from the outer surface of the corrugated tube, while the rib is formed on each link of the guide protector. It is also preferable that a fitting groove to be inserted is provided to prevent the corrugated tube from rotating within the link.

  According to the above configuration, the cross-sectional shape of the corrugated tube in the region covered by the guide protector by fitting the rib provided in the axial direction on the outer surface of the corrugated tube and the fitting groove provided on the inner surface of each link of the guide protector. Even if is circular, the corrugated tube does not rotate in the link, so that twisting of the harness and the like can be prevented. Similarly, since the guide protector does not rotate around the corrugated tube, it is possible to prevent the link bending direction from changing during the following operation.

The corrugated tube is preferably relatively soft and flexible. For example, polypropylene (PP), ethylene-propylene rubber (EPDM), or various elastomers can be used. Moreover, as the said corrugated tube, you may use the split-shaped corrugated tube which provided the slit in the length direction other than a normal corrugated tube.
The harness to which the corrugated tube is attached is not particularly limited, and may be a wire harness or a flat harness.

The link constituting the guide protector is preferably formed of a high-hardness resin. For example, polybutylene terephthalate (PBT), polyamide (PA), polyacetal (POM) resin, or the like is preferably used.
Further, the link is composed of upper and lower divided bodies divided into two along the length direction, and the link is formed by engaging a lock portion and a locked portion provided in each divided body. May be. Thereby, a corrugated tube and a link can be more easily fitted.

  As described above, according to the present invention, since the corrugated tube is attached to the entire length of the harness in the cross wiring area, the cost can be reduced compared to the conventional structure in which the caterpillar-shaped cable guide is attached to the entire length of the harness. In addition, the flexibility of the corrugated tube can also absorb changes in the vertical direction of the sliding door, so that the harness can smoothly follow the movement of the sliding door without providing a separate vertical moving mechanism. . Moreover, since there is no portion where the harness is exposed to the outside by attaching a corrugated tube to the entire length of the harness, an exterior material (tube that is necessary to prevent the harness from being exposed from the gap when the cable guide is attached. Body) becomes unnecessary, and the number of parts can be reduced and the structure can be simplified.

  In addition, as described above, the corrugated tube attached to the entire length of the harness can be partially covered with the guide protector for restricting bending, and therefore the portion of the corrugated tube that easily interferes with peripheral members. For example, the bending protector guide protector can be attached to a place where the bending angle of the harness needs to be regulated. Therefore, the bending angle of the harness can be effectively controlled without significantly increasing the number of parts, and interference between the harness and the peripheral member can be prevented.

  As described above, the guide protector formed by linking a plurality of links is provided with the concave and convex engaging portions that fit the concave and convex portions of the corrugated tube on the inner surface of each link. The guide protector can be securely fixed to the required position of the corrugated tube by simply fitting the concave and convex portions of the corrugated tube at the required position.

  In addition, as described above, a protrusion is provided at one end in the length direction of a pair of opposing sides of each link, and a groove that opens in a V shape is provided at the other end. By adopting a configuration that allows the angle bendable, the bend angle between the linked links, and further the bend angle of the harness in the corrugated tube can be regulated within the range of the predetermined angle.

  Further, in a pair of sides orthogonal to a pair of opposite sides, a cutout is provided on one end side in the length direction of the link and a protruding portion is provided on the other end side, and the protruding portion protrudes in the notch between adjacent links. With the configuration of overlapping, it is impossible to bend in the overlapping direction, and the bending between the links can be limited only to the bending direction described above.

  In addition, as described above, since the flexible corrugated tube is attached to the entire length of the harness in the cross wiring area, the corrugated tube is directly attached to the mounting bracket that is fixed to the vehicle body and the sliding door without interposing a rotating mechanism. By simply fixing, the harness can smoothly follow the movement of the sliding door. That is, since it is not necessary to provide a rotation mechanism or the like on the mounting bracket, the structure can be further simplified.

Embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a first embodiment of the present invention.
As shown in FIG. 1, a corrugated tube 11 (made of polypropylene resin) having an elliptical cross section is attached to the entire length of the wire harness W / H routed between the vehicle body 30 and the slide door 31. The bending restrictor guide protector 12 is partially covered. That is, the corrugated tube 11 and the guide protector 12 form an exterior material 10 that protects and guides the wire harness W / H.

Specifically, the guide protector 12 is formed by connecting two rectangular cylindrical links 13 as shown in FIG. 2 as shown in FIGS.
The link 13 is made of polybutylene terephthalate resin. As shown in FIG. 3, an annular concavo-convex engaging portion 14 that fits with the concavo-convex portion of the corrugated tube 11 is continuously provided in the link length direction on the inner surface of the link 13. Provided.

Further, as shown in FIG. 2A, a trapezoidal protrusion 16 is provided at one end in the length direction of a pair of opposing sides 15 of the link 13, and a groove 17 that opens in a V shape is provided at the other end. As shown in FIG. 4, the protrusions 16 are fitted into the grooves 17 so as to be bent at a predetermined angle between the adjacent links 13 to link the links 13 together.
That is, one side 16a of the projection 16 of the adjacent link 13 is brought into contact with one side 17a of the groove 17 that opens in a V shape, and the projection 16 is fitted in the groove 17 [FIG. )] Until the other side 16b of the protrusion 16 is brought into contact with the other side 17b of the groove 17 and the protrusion 16 is fitted in the groove 17 (FIG. 4B). By setting the range, the bending angle of the link 13 is restricted, and thus the bending angle of the wire harness W / H inserted inside is also restricted.
In this embodiment, the angle θ formed by the axis L2 of the link 13 when the link 13 is bent to the maximum is 25 to 35 with respect to the axis L1 of the link 13 when the links 13 are connected in a straight line. The angle is restricted to about °.

Further, as shown in FIGS. 2A and 2B, a notch 19 is provided on one end side in the length direction of the link 13 in a pair of sides 18 orthogonal to the pair of opposite sides 15 of the link 13. 4 and 5, the protruding portion 20 is protruded from the notch 19 between the adjacent links 13 and overlapped at the end portion in the length direction of the link 13. ing.
In this embodiment, the total length d of the cutout 19 is about 25% of the total length D of the link, and the link 20 connected in a straight line as shown in FIG. Are protruding and stacked. As a result, bending in the overlapping direction (vertical direction in the present embodiment) is disabled.

  On the other hand, as shown in FIGS. 6A and 6B, a vehicle body side mounting bracket 32 and a slide door side mounting bracket 33 are fixed to the vehicle body 30 and the slide door 31, respectively. The mounting brackets 32 and 33 are provided with fan-shaped openings 32a and 33a for drawing in the wire harness W / H to which the corrugated tube 11 is attached, and annular concave and convex engaging portions 32b and 33b that fit with the concave and convex portions of the corrugated tube 11. The corrugated tube 11 is attached to the concave and convex engaging portions 32b and 33b by fitting the concave and convex portions of the corrugated tube 11 drawn into the mounting brackets 32 and 33 from the openings 32a and 33a. It is directly fixed to.

  The fan-shaped regions of the openings 32a and 33a become the movable range of the corrugated tube 11 fixed to the concave and convex engaging portions 32b and 33b, and both sides 32a-1 and 33a-1 of the openings 32a and 33a are the corrugated tube 11. It plays a role in regulating the bending of the body. An angle θ1 formed by both sides 32a-1 of the opening 32a of the vehicle body side mounting bracket 32 is about 90 to 120 °, and an angle θ2 formed by both sides 33a-1 of the opening 33a of the sliding door side mounting bracket 33 is set. The angle is about 100 to 150 °.

  Further, as shown in FIG. 1, the guide protector 12 in which the two links 13 are connected to each other is mounted on the corrugated tube 11 at the crossover routing portion adjacent to the vehicle body side mounting bracket 32 and the slide door side mounting bracket 33. Yes. In the present embodiment, the guide protector 12 is attached at two positions with an interval close to the vehicle body side mounting bracket 33.

The wire harness W / H to which the corrugated tube 11 is attached is routed between the vehicle body 30 and the slide door 31 in the horizontal direction, and the projections 16 and the grooves 17 of the links 13 of the guide protector 12 are provided on the upper and lower sides. Accordingly, the links 13 can be bent in the horizontal direction and cannot be bent in the vertical direction.
The link 13 is composed of upper and lower divided bodies 13A and 13B that are divided into two along the length direction, and the upper and lower divided bodies 13A and 13B are locked and integrated to form the link 13. .

FIG. 1 shows a wiring structure of a wire harness W / H spanned between a vehicle body 30 and a slide door 31 in this embodiment. P1 in FIG. 1 is when the slide door 31 is fully opened, and P2 is a slide. The state when the door 31 is fully closed is shown.
When the sliding door 31 is fully opened, the wire harness W / H is positioned between the tire house 34 and the lower arm 35. When the sliding door 31 is fully closed, the wire harness W / H is positioned between the slide rail 36 and the weather strip 37. To do.

  As described above, since the corrugated tube 11 is attached to the entire length of the wire harness W / H in the crossover region, the cost can be reduced compared to the conventional structure in which the caterpillar-shaped cable guide is attached to the entire length of the harness. In addition, because the flexibility of the corrugated tube 11 can also absorb changes in the vertical direction of the slide door 31, the wire harness W / H smoothly follows the movement of the slide door 31 without providing a separate vertical moving mechanism. It becomes possible to make it. In addition, since the corrugated tube 11 is attached to the entire length of the wire harness W / H so that there is no portion where the wire harness W / H is exposed to the outside, the harness is prevented from being exposed through the gap when the cable guide is attached. This eliminates the need for the exterior material (tube body) required for the construction, reduces the number of parts, and simplifies the structure.

  Further, as described above, the corrugated tube 11 attached to the entire length of the wire harness W / H can be partially covered with the guide protector 12 for bending restriction. The guide protector 12 can be mounted at a position close to the mounting brackets 32 and 33 that easily receive interference with peripheral members. Therefore, the bending angle of the wire harness W / H can be controlled effectively without significantly increasing the number of parts, and interference between the wire harness W / H and peripheral members can be prevented.

  As described above, the guide protector 12 formed by connecting a plurality of links 13 is provided with the concave and convex engaging portions 14 that fit the concave and convex portions of the corrugated tube 11 on the inner surface of each link 13. The guide protector 12 can be reliably fixed to the required position of the corrugated tube 11 only by fitting the unevenness locking portion 14 to the unevenness of the corrugated tube 11 at the required position.

  Further, as described above, the protrusions 16 are provided at one end in the length direction of the pair of opposing sides 15 of each link 13, and the groove 17 that opens in the V-shape is provided at the other end. Is configured to be fitted to the groove 17 so as to be bent at a predetermined angle, so that the bending angle between the linked links 13 and the bending angle of the wire harness W / H in the corrugated tube 11 are within the range of the predetermined angle. Can be regulated.

  Furthermore, in a pair of sides 18 orthogonal to the pair of opposite sides 15, a cutout 19 is provided on one end side in the length direction of the link 13 and a protruding portion 20 is provided on the other end side. By adopting a configuration in which the protruding portion 20 is overlapped with the protrusion 19, the bending in the overlapping direction becomes impossible, and the bending between the links 13 can be limited only to the bending direction described above. Therefore, as described above, when the wire harness W / H is routed horizontally between the vehicle body 30 and the slide door 31, and the projections 16 and the grooves 17 of the links 13 of the guide protector 12 are provided on the upper and lower sides. The links 13 can be bent in the horizontal direction and cannot be bent in the vertical direction. By making it impossible to bend in the vertical direction, the corrugated tube 11 can be prevented from hanging down.

  Further, as described above, since the flexible corrugated tube 11 is attached to the entire length of the wire harness W / H in the crossover wiring region, the mounting brackets 32 and 33 fixed to the vehicle body 30 and the slide door 31 are provided with a rotation mechanism or the like. The wire harness W / H can smoothly follow the movement of the sliding door 31 only by directly fixing the corrugated tube 11 without interposing any of the above. That is, since it is not necessary to provide a rotation mechanism or the like on the mounting brackets 32 and 33, the structure can be simplified.

  Further, as described above, by making the cross-sectional shape of the corrugated tube 11 in the intermediate region where the guide protector 12 is not packaged into an ellipse, the straightness of the wire harness W / H is improved, and space-saving and smooth follow-up operation is achieved. It can be carried out. Furthermore, since the cross-sectional shape of the corrugated tube 11 not only in the intermediate region but also in the region covered with the guide protector 12 is an ellipse, it is possible to prevent the corrugated tube 11 from rotating in the link 13.

FIG. 7 shows a second embodiment.
In the second embodiment, the shapes of the protrusions 16 and the grooves 17 are the same as those of the first embodiment except that the tips are arcuate as shown in FIG.

  Also in the second embodiment, the same effect as in the first embodiment can be obtained, and the wire harness W / H spanned between the vehicle body 30 and the slide door 31 can smoothly follow the movement of the slide door 31. In addition, it is possible to prevent the interference between the wire harness W / H and the peripheral members by controlling the bending angle of the wire harness W / H in the following operation.

8 and 9 show a third embodiment.
In the third embodiment, the corrugated tube 41 mounted on the guide protector 12 has a circular cross-sectional shape, and as shown in FIG. 8, one rib 42 extending in the axial direction is provided on the outer surface of the corrugated tube 41. ing.
Further, as shown in FIG. 9, a fitting groove 21 into which a rib 42 is inserted is provided on the inner surface side of each link 13 constituting the guide protector 12.
On the other hand, the cross-sectional shape of the corrugated tube (not shown) in the intermediate region not covered with the guide protector 12 is the same as that of the first embodiment, and the corrugated tube 41 having a circular cross section and the corrugated tube having a cross-sectional elliptical shape are arranged. They are connected by tape winding.
Except for the points described above, the second embodiment is the same as the first embodiment.

  In the third embodiment, the same effect as in the first embodiment can be obtained, and the wire harness W / H spanned between the vehicle body 30 and the slide door 31 can smoothly follow the movement of the slide door 31. In addition, it is possible to prevent the interference between the wire harness W / H and the peripheral members by controlling the bending angle of the wire harness W / H in the following operation.

Further, as described above, the ribs 42 provided in the axial direction on the outer surface of the corrugated tube 41 and the fitting grooves 21 provided on the inner surfaces of the links 13 of the guide protector 12 are fitted with the guide protector 12. Even if the cross-sectional shape of the corrugated tube 41 in the region is circular, the corrugated tube 41 does not rotate in the link 13, so that twisting of the wire harness W / H can be prevented. Similarly, since the guide protector 12 does not rotate around the corrugated tube 41, it is possible to prevent the bending direction of the link 13 from changing during the following operation.
In the present embodiment, the cross-sectional shape of the corrugated tube in the intermediate area not covered with the guide protector 12 is an elliptical shape, but the corrugated tube having a circular cross-section is attached to the entire length of the wire harness in the crossover area.
