By the way, in the configuration described in Patent Document 1 in which the wire harness is temporarily placed with a temporary placement component as described above, there is no hole for locking the locking claw of the temporary placement component at the location where the wire harness is desired to be temporarily placed. In this case, there is a problem in that the wire harness cannot be temporarily placed.

The present invention was made by focusing on the problems existing in the prior art. The purpose is to provide a wire harness unit that can reliably temporarily place a wire harness.

Below, means for solving the above problems and their effects will be described.
A wire harness unit that solves the above problem includes a wire harness, a clamp provided on the wire harness and attachable to the main attachment part, and provided at a position different from a position in the wire harness where the clamp is provided. A wire harness unit comprising a protector that is fixed to a fixing part to restrict a path of the wire harness, and the protector is provided with a temporary support part that can temporarily support the clamp. This is the summary.

According to this configuration, since the protector is provided with a temporary support part that can temporarily support the clamp, the clamp provided on a part of the wire harness can be temporarily supported by the temporary support part of the protector, thereby supporting the wire harness. It can be safely placed temporarily.

In the wire harness unit, the clamp includes an attachment part that can be attached to the main attachment part, and a support part that can be temporarily supported by the temporary support part.

According to this configuration, since the clamp is separately provided with a mounting part that can be attached to the main mounting part and a support part that can be temporarily supported by the temporary support part, the mounting part can be securely attached to the main mounting part. In addition, the support section can be reliably temporarily supported by the temporary support section.

In the above-mentioned wire harness unit, the attachment portion is configured such that it cannot be temporarily supported by the temporary support portion, and the support portion is configured such that it cannot be attached to the main attachment portion.

According to this configuration, when the support part of the clamp is temporarily supported by the temporary support part, the mounting part of the clamp may not be temporarily supported by the temporary support part by mistake, and the mounting part of the clamp may be temporarily supported by the temporary support part when the mounting part of the clamp is attached to the main mounting part. It is possible to prevent the support part from being attached to the main attachment part by mistake.

In the wire harness unit, the protector is provided with a suppressing portion that suppresses the temporary supporting portion from releasing the temporary supporting state of the clamp when the temporary supporting portion temporarily supports the clamp. The main point is that

Hereinafter, one embodiment of a wire harness unit will be described according to the drawings.
As shown in FIG. 1, the wire harness unit 11 is arranged, for example, on a body side wall 12 and a body bottom wall 13, which are an example of a fixed part of a vehicle body. The body side wall 12 and the body bottom wall 13 are integrally formed so as to be perpendicular to each other. The wire harness unit 11 includes a wire harness 14, a synthetic resin clamp 15 provided on the wire harness 14, and a synthetic resin protector provided on the wire harness 14 at a position different from the position where the clamp 15 is provided. 16.

The protector 16 has a hollow rectangular parallelepiped shape, and is fixed to the front surface of the body side wall 12 at the rear wall 17, thereby regulating the path of the wire harness 14. The wire harness 14 extends so as to pass through the left and right side walls 18 of the protector 16 that face each other. A hook portion 20, which is an example of a temporary support portion that can temporarily support the clamp 15, is formed at the center of the front surface of the front wall 19 of the protector 16, which faces the rear wall 17.

As shown in FIGS. 1 and 2, the hook portion 20 has an L-shaped plate shape that projects slightly forward from the center of the front surface of the front wall 19 and then extends upward to be bent at a right angle. On the upper side of the hook part 20 on the front surface of the front wall 19 of the protector 16, there is a restraint that prevents the clamp 15 from being temporarily supported by the hook part 20 when the clamp 15 is temporarily supported by the hook part 20. A convex portion 21 is provided so as to protrude forward.

The amount of forward protrusion of the convex portion 21 from the front surface of the front wall 19 of the protector 16 is set to about half the amount of the hook portion 20. The convex portion 21 extends in the left-right direction, and has approximately the same length in the left-right direction as the hook portion 20. A gap 22 is formed between the upper end of the hook portion 20 and the lower end of the convex portion 21. A screw hole 25 is formed on the lower side of the protector 16 on the front surface of the body side wall 12 for fixing a later-described annular mounting member 23 (see FIG. 6) with a hexagonal bolt 24 (see FIG. 6).

A fixture 26 to which the clamp 15 can be attached is provided at the center of the upper surface of the body bottom wall 13. The fixture 26 has a rectangular plate-shaped base end 28 extending in the left-right direction and fixed to the body bottom wall 13 by bolts 27, and a rectangular plate-shaped intermediate part extending straight upward from the left end of the base end 28. portion 29, and a rectangular plate-shaped book attachment portion 30 extending straight from the upper end of the intermediate portion 29 toward the left. A locking hole 31 is formed at the tip of the main mounting portion 30 so as to pass therethrough. Note that the clamp 15 is provided in the middle of a portion of the wire harness 14 extending from the left side wall 18 of the protector 16.

As shown in FIGS. 1 and 3 to 5, the clamp 15 has a main body portion having a substantially rectangular parallelepiped shape and having an insertion passage 32 therein as an example of a mounting portion that can be attached to the main mounting portion 30 of the mounting tool 26. 33, and a fixing belt 34 integrally formed with the main body portion 33. In the description of FIGS. 3 to 5, the height direction of the main body 33 in the clamp 15 is assumed to be the Z direction, the width direction of the main body 33 is assumed to be the X direction, and the depth direction of the main body 33 is assumed to be the Y direction.

The insertion passage 32 within the main body portion 33 extends in the Z direction. The two surfaces of the main body portion 33 in the Z direction are a first end surface 35 and a second end surface 36, respectively. Both ends of the insertion passage 32 are open at a first end surface 35 and a second end surface 36, respectively. Therefore, the insertion passage 32 communicates the first end surface 35 and the second end surface 36. The main mounting portion 30 of the mounting tool 26 can be inserted into the insertion passage 32 from an opening on the second end surface 36 side. By inserting the main attachment part 30 into the insertion passage 32, the clamp 15 is attached to the main attachment part 30 in the insertion passage 32.

The two side walls of the main body portion 33 in the Y direction are a first side wall 37 and a second side wall 38, respectively. The fixing belt 34 has one end connected to the outer surface of the first side wall 37 of the main body 33 at a position slightly closer to the second end surface 36 than the center in the Z direction, and has a bent portion 39 bent at right angles to the other end. have.

A first locking pawl 40 is provided at the tip of the bent portion 39 . A second locking claw 41 capable of locking the first locking claw 40 is provided at the end of the inner surface of the first side wall 37 on the first end surface 35 side. Then, the clamp 15 is fixed to the wire harness 14 by locking the first locking claw 40 with the second locking claw 41 while the fixing belt 34 is wrapped around a part of the wire harness 14.

A belt-shaped locking member 42 extending along the insertion passage 32 is provided at a position adjacent to the insertion passage 32 on the second side wall 38 side within the main body portion 33 . The locking member 42 has an end on the second end face 36 side that is a fixed end fixed within the main body portion 33, and an end on the first end face 35 side as a free end. The end of the locking member 42 on the first end surface 35 side does not reach the first end surface 35 and is located near the first end surface 35 . The lock member 42 is elastically deformable in the Y direction using the end on the second end surface 36 side as a fulcrum.

A third locking pawl 43 that is locked by the locking hole 31 when the main mounting portion 30 is inserted into the insertion path 32 is formed in the center of the surface of the locking member 42 on the side of the insertion path 32 in the Z direction. has been done. The third locking pawl 43 has a slope 44 whose protrusion height from the surface of the locking member 42 on the insertion passage 32 side gradually increases from the second end surface 36 side to the first end surface 35 side. The third locking pawl 43 has a right triangular shape when viewed from the X direction.

A rectangular notch 45 is formed at the end of the second side wall 38 of the main body 33 in the X direction at the end thereof on the first end surface 35 side. The end of the notch 45 on the second end surface 36 side reaches approximately the center of the second side wall 38 in the Z direction. A portion of the second side wall 38 that corresponds to the notch 45 in the Z direction is a hooking portion 46 that is an example of a support portion that can temporarily support the clamp 15 by being hooked to the hook portion 20 .

An allowable space 47 is formed between the hook portion 46 and the lock member 42 to allow elastic deformation of the lock member 42 toward the hook portion 46 . The hook portion 20 is accommodated in this allowable space 47 when the hook portion 46 is hooked to the hook portion 20. When the hook portion 46 is hooked to the hook portion 20, a hook portion 46 is attached to a portion corresponding in the Z direction to the notch portion 45 in the corner portion formed by the second end surface 36 of the main body portion 33 and the outer surface of the second side wall 38. A housing recess 48 is formed in which the convex portion 21 is accommodated.

The width of the notch portion 45 in the X direction is set to be wider than the width of the hook portion 20 and narrower than the width of the main attachment portion 30. Therefore, the hooking part 46 cannot be engaged with the main mounting part 30, so that it cannot be attached to the main mounting part 30. Further, the distance from the outer surface of the second side wall 38 to the insertion passage 32 in the Y direction is longer than the distance from the front surface of the front wall 19 of the protector 16 to the front end of the hook portion 20. For this reason, the insertion passage 32 cannot be hooked by the hook portion 20, and therefore cannot be temporarily supported by the hook portion 20.

Next, the operation of the wire harness unit 11 when the mounting member 23 is fixed to the lower side of the protector 16 on the front surface of the body side wall 12 using the hexagonal bolt 24 will be explained.
For example, on a vehicle assembly line, the position of the wire harness 14 is not stable before the clamp 15 provided on the wire harness 14 is attached to the main attachment part 30 of the attachment 26. For example, the wire harness 14 often hangs down in front of the screw hole 25 in the body side wall 12, as shown by the two-dot chain line in FIG. In such a case, when attempting to fix the mounting member 23 to the screw hole 25 with the hexagonal bolt 24, the wire harness 14 hanging down from the protector 16 will get in the way.

Therefore, it is necessary to temporarily place the wire harness 14 hanging from the protector 16 in a position where it will not interfere with the above-mentioned work until the above-mentioned work is completed. In this regard, in the wire harness unit 11 of this embodiment, as shown in FIG. 14 can be temporarily placed in a position where it will not interfere with the work until the work is completed, so the work can be carried out efficiently.

When the clamp 15 provided on the wire harness 14 hanging from the protector 16 is temporarily supported by the hook part 20 of the protector 16, the hook part 46 of the clamp 15 is attached to the upper end of the hook part 20, as shown in FIG. It is inserted into the space inside (rear side) of the hook part 20 through the gap 22 between the lower end of the convex part 21 and the lower end of the protrusion part 21 . At this time, the hook portion 20 is accommodated in the allowable space 47 of the clamp 15, and the convex portion 21 is accommodated in the accommodation recess 48 of the clamp 15.

Thereby, the clamp 15 is temporarily supported by being hooked to the hook portion 20 at the hook portion 46 . Therefore, the wire harness 14 hanging down from the protector 16 is temporarily placed at a position in front of the protector 16 where it does not interfere with the above-mentioned work. At this time, the protrusion 21 makes it difficult for the hook 46 to slip out of the gap 22 between the upper end of the hook 20 and the lower end of the protrusion 21, so the hook 20 temporarily holds the clamp 15 during the above operation. The convex portion 21 prevents the supporting state from being released.

After the above-mentioned work is completed, the hook part 46 of the clamp 15 is pulled out from the gap 22 between the upper end of the hook part 20 and the lower end of the convex part 21. As a result, the temporary support state of the clamp 15 by the hook portion 20 is released. Thereafter, as shown in FIGS. 8 and 9, the clamp 15 is moved so that the main attachment part 30 of the attachment tool 26 is inserted into the insertion passage 32 of the clamp 15 from the opening on the second end surface 36 side. At this time, in the process in which the slope 44 of the third locking pawl 43 of the locking member 42 slides on the tip of the main mounting part 30, the locking member 42 is pressed toward the allowable space 47 by the main mounting part 30.

Therefore, the locking member 42 is elastically deformed so as to bend toward the allowable space 47 side. Then, when the third locking pawl 43 of the locking member 42 approaches the locking hole 31 of the main attachment portion 30, the locking member 42 returns to its original shape before elastic deformation by its own elastic restoring force. Then, the third locking pawl 43 of the locking member 42 is inserted into the locking hole 31 of the main attachment portion 30 and locked. Thereby, the clamp 15 is locked in the state attached to the main attachment part 30.

According to the embodiment described in detail above, the following effects are exhibited.
(1) The wire harness unit 11 is provided with a wire harness 14, a clamp 15 provided on the wire harness 14 and attachable to the main attachment part 30, and a position on the wire harness 14 that is different from the position where the clamp 15 is provided. and a protector 16 that is fixed to the body side wall 12 to restrict the route of the wire harness 14. The protector 16 is provided with a hook portion 20 that can temporarily support the clamp 15. According to this configuration, since the hook part 20 that can temporarily support the clamp 15 is provided on the protector 16, the clamp 15 provided on a part of the wire harness 14 can be temporarily supported by the hook part 20 of the protector 16. In particular, the portion of the wire harness 14 where the clamp 15 is provided and the surrounding portion thereof can be reliably temporarily placed.

(2) In the wire harness unit 11, the clamp 15 includes an insertion passage 32 that can be attached to the main attachment part 30, and a hook part 46 that can be temporarily supported by the hook part 20. According to this configuration, the clamp 15 is separately provided with the insertion passage 32 that can be attached to the main attachment part 30 and the hook part 46 that can be temporarily supported by the hook part 20. It can be reliably attached to the portion 30, and the hook portion 46 can be reliably temporarily supported by the hook portion 20.

(3) In the wire harness unit 11, the insertion passage 32 of the clamp 15 is configured such that it cannot be temporarily supported by the hook portion 20, and the hook portion 46 of the clamp 15 is configured such that it cannot be attached to the main attachment portion 30. According to this configuration, when temporarily supporting the hook part 46 of the clamp 15 on the hook part 20, the insertion passage 32 of the clamp 15 may be temporarily supported on the hook part 20 by mistake, or the insertion passage 32 of the clamp 15 may be temporarily supported on the hook part 20. When attaching to the main attachment part 30, it is possible to prevent the hanging part 46 of the clamp 15 from being attached to the main attachment part 30 by mistake.

(4) In the wire harness unit 11, when the hook portion 20 of the protector 16 temporarily supports the hook portion 46 of the clamp 15, the temporary support state of the hook portion 46 by the hook portion 20 is released. A convex portion 21 is provided to suppress this. According to this configuration, when the hook portion 20 temporarily supports the hook portion 46 of the clamp 15, the convex portion 21 can prevent the hook portion 20 from releasing the temporary support state of the hook portion 46.
