DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a wire harness mounting apparatus for mounting and wiring a wire harness such as an ABS sensor harness or a tire pressure warning harness along an axle housing of an automobile. is there.

[0002]

2. Description of the Related Art For example, as shown in FIG. 10, a wire harness 1 such as an ABS sensor harness or a tire air pressure warning harness is attached to an axle housing 2A of an automobile or the like. Conventionally, as shown in FIGS. 10 and 11, these wire harnesses 1 have a sheet metal clip 42 that supports the wire harness 1.
Are fixed to the axle housing 2A at appropriate intervals by welding 26 (see FIG. 11).
Was attached to the axle housing 2A by tightening it with a nut 24.

[0003]

However, when the bolt 22 is directly welded and mounted on the axle housing 2A as in the prior art, the bolt 22 is welded at a number of places corresponding to the number of bolts 22 installed. Therefore, the number of mounting steps of the wire harness 1 increases, and there is a problem that it takes much time and increases the cost.

Further, in this conventional technique, when the nut 22 is tightened by an impact wrench or the like, the sheet metal clip 42 rotates together with the rotation of the nut 24, and each time, it is necessary to correct the position of the sheet metal clip 42. In this respect, there is also a problem that requires labor.

[0005] As shown in FIG. 12, another component such as a detent component 50 having a side wall 50 a that engages with the sheet metal clip 42 and suppresses rotation of the sheet metal clip 42 is attached to the bolt 22. It is performed to prevent the sheet metal clips 42 from rotating together. However, in this case, it is necessary to attach the rotation preventing parts 50 to each bolt 22 by welding. Since parts are used, there is a problem that the weight increases.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems by reducing the labor and cost for mounting the wire harness, and preventing the members supporting the harness from rotating together, and It is an object of the present invention to provide a wire harness mounting device capable of facilitating a mounting operation of a wire harness.

[0007]

According to the present invention, as a first means for solving the above-mentioned problems, there are provided a plurality of harness support members for supporting a wire harness to be attached to an attached body at intervals. A holding member that is fixed to both ends of the attached body and holds the plurality of harness support members, wherein the harness support member is a clip having a pin portion that can be removably inserted into a clip mounting hole of the holding member. An object of the present invention is to provide a wire harness mounting device characterized in that the wire harness is formed.

As described above, when the harness support member is attached to the object to be mounted via the holding member and the harness support member is a clip having a pin portion that can be removably inserted into the mounting hole of the holding member, Is sufficient only at both ends of the holding member.Since the wire harness can be attached to the object to be attached simply by inserting its pin portion into the clip attaching hole of the holding member without welding the harness support member to the holding member, The process of attaching the wire harness is simplified, and labor and cost can be reduced.

Further, since the clip serving as the harness support member can be fixedly attached to the holding member only by inserting its pin portion into the clip mounting hole of the holding member instead of fastening with a nut, the harness support member can be fixed. It does not rotate with the nut.

In the first means for solving the problems, the pin portion of the clip may be, for example, a crack pin whose diameter can be reduced by the wall of the clip mounting hole when penetrating the clip mounting hole.

Further, the present invention provides, as a second means for solving the above-mentioned problems, a plurality of harness support members for supporting a wire harness to be attached to an attached body at intervals, and a plurality of harness support members attached to the attached body. A holding member that is fixedly attached at both ends and holds the plurality of harness support members, wherein the harness support member is fastened and held to the holding member by a fastening member, and the holding member corresponds to a holding position of the harness support member. A wire harness mounting device is provided, which has a detent part formed by bending a part of the holding member to engage with the harness support member to prevent the harness support member from rotating.

As described above, when the harness supporting member fixed by tightening the bolts and nuts is held by the holding member, the bolts are covered at a number of places to attach the harness supporting member to the object without passing through the holding member. Unlike the prior art, which had to be welded directly to the mounting body, it is not necessary to weld the bolt to the holding member, and if a part of the holding member is bent to form a detent part, It is possible to prevent the harness support member from rotating together without welding another part, so that labor and cost can be reduced, and the harness support member does not rotate together. An increase in weight can be suppressed as compared with the case where separate parts are individually welded to the holding member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a mounting device 10 for a wire harness 1 according to the present invention. Harness support member 12 for supporting wire harness 1 to be attached to
And a holding member 14 for holding.

In the illustrated embodiment, the mounting member 2
Is a vehicle axle housing 2 as shown in FIG.
A is shown, but this is only an example, and the mounting device 10 of the present invention is also applicable to the mounting of the wire harness 1 to other parts of the automobile and other structures other than the automobile. Of course you can.

As shown in FIGS. 1 and 2, the holding member 14 is elongated so as to correspond to the wiring path of the wire harness 1, and the axle housing 2A as the body 2 to be mounted.
Is formed in a thin plate shape that is slightly curved so as to follow. This is to conform to the shape of the elongated wire harness 1 and arrange it along the axle housing 2A so that no extra space is required for mounting the wire harness 1. In addition,
The holding member 14 can be formed from a steel plate or the like.

As shown in FIG. 2, the holding member 14 has both ends 14a (only one end is shown in the drawing).
In addition, a fixing hole 16 for fixing the holding member 14 to the axle housing 2A is formed, and a clip mounting hole 18 for mounting a clip 28, which is a harness support member 12 described later, is formed. In the illustrated embodiment, a plurality of the clip mounting holes 18 are formed at appropriate intervals in the longitudinal direction from the fixing holes 16 at both ends 14a,
As shown in FIG. 1, a plurality of harness support members 12 are attached to the plurality of clip attachment holes 18 by a method described later. As a result, the plurality of harness support members 12 support the wire harness 1 at appropriate intervals, as shown in FIG. The number of the clip mounting holes 18 and the number of the harness support members 12 can be appropriately set as needed. However, in general, it is better to set the number to a plurality or more to some extent.
Can be stably supported, which is preferable.

As shown in FIGS. 1 and 3, the holding member 14 has both ends 14a fixed to an axle housing 2A which is the body 2 to be mounted. In the illustrated embodiment, the holding member 14 is, as shown in FIGS.
It is attached to the axle housing 2A via an L-shaped bracket 20 fixed and attached to the axle housing 2A, which is the attached body 2, by welding 26. Specifically, as shown in FIG. 3 in particular, the holding member 14 is provided with bolts 22 fixedly attached so that the fixing holes 16 at both ends 14 a extend upward to the L-shaped bracket 20.
Then, it is fixed to the bracket 20 by tightening with the nut 24 and attached to the axle housing 2A.

In the illustrated embodiment, the holding member 12 is attached via the bracket 20 in a more stable and strong manner than when the holding member 12 is fastened to the bolt 24 directly fixed to the axle housing 2A. This is because the holding member 14 can be fixed at the same time. Therefore,
Unlike the illustrated embodiment, the holding member 14 has a sufficient strength, for example, by directly welding the both ends 14a of the holding member 14 to the axle housing 2A while keeping a certain sufficient contact area with the axle housing 2A. If the bracket 20 can be fixed, the bracket 20 need not always be used.

As shown in FIG. 1, the vertical wall 20A of the L-shaped bracket 20 has a role of changing the wiring direction of the wire harness 1 and guiding the wire harness 1 according to the layout. Therefore, for example, a sheet metal clip 42 or the like similar to the conventional one shown in FIG.
4, if the wiring direction of the wire harness 1 can be changed by another method such as guiding the wire harness 1 by the sheet metal clip 42, the bracket 20 does not necessarily form the vertical wall 20A to form an L-shape. do not have to. In addition, even when the wiring direction of the wire harness 1 does not need to be changed, the bracket 20 does not necessarily need to be formed in an L-shape, and may of course have another shape.

The harness support member 12 comprises a clip 28 as shown in FIGS.
Has a clip body 30 and a pin 32 formed to extend downward from the clip body 30.

As shown in FIG. 4, the clip body 30 has a support ring portion 34 through which the wire harness 1 is supported. The support ring 34 may be a simple hole 34A formed in the clip body 30,
Further, as shown in FIG. 4, it may be composed of a hole 34A and a harness bracket 34B fitted into the hole 34A. In any case, before or after the clip 28 is attached to the holding member 14, the wire harness 1 can be supported by penetrating the support ring 34 from the front side of the clip body 30.

However, the method for penetrating the wire harness 1 is not particularly limited. For example, in the case of the former (only the hole 34A), as described later,
After passing the wire harness 1 from the lower end of the pin portion 32, which is 2A, to the clip body 30, the split pin 32
A can be closed so that the wire harness 1 is penetrated and supported. In the case of the latter (the hole 34A and the harness bracket 34B), the wire harness 1
Clip body 3 with the harness bracket 34B
The wire harness 1 may be supported by penetrating through the wire harness 1. In addition, as shown in FIG. 4, a plurality of support ring portions 32 may be provided as necessary, so that a plurality of wire harnesses 1 can be simultaneously penetrated and supported, or a single support ring portion 32 may be provided. There may be.

As shown in FIG. 4, the pin portion 32 is formed so as to be detachably inserted into the clip mounting hole 18 of the holding member 14. Specifically, in the illustrated embodiment, this pin portion 32 is, as shown in FIG.
When passing through the clip mounting hole 18, the clip mounting hole 18
And a crack pin 32A which can be reduced in diameter by the wall 18a and has a flange portion 32b at the tip. Accordingly, as shown in FIG. 4A, the cracked pin 32A, which is the pin portion 32, is pushed into the clip mounting hole 18 from above and penetrates the clip mounting hole 18 while reducing the diameter.
As shown in (B), the diameter is automatically expanded again to the original state by the elastic restoring action of the crack pin 32A itself.

As a result, the clip 28 is moved to the position shown in FIG.
As shown in FIG. 7, the outer peripheral surface 32a of the pin portion 32 is engaged with the wall 18a of the clip mounting hole 18, and the flange portion 32b is engaged with the lower surface 14b of the holding member 14, and is held by the holding member 14. In this case, the clip 28 is
A is held by the holding member 14 while being prevented from falling off by the flange portion 32b of A. After that, when it is necessary to remove the holding member 14 for repair, inspection, etc., the flange portion 32b is pinched. The split pin 32A can be removed by pulling it out from the clip mounting hole 18 while reducing its diameter. It is preferable that the outer periphery of the flange portion 32b of the pin portion 32 be a slightly curved tapered surface so that the pin portion 32 can be smoothly inserted into the clip mounting hole 18, as shown in FIG.

The clip 28 has a cracked pin 32A which can reduce the diameter of the pin portion 34 and can be restored by elasticity.
It is desirable to form from a resin because it has good moldability. Thus, the weight of the clip 28 can be reduced. Also, the clip 28
Preferably, an engaging flange 36 that engages with the upper surface 14c of the holding member 14 is preferably formed between the clip body 30 and the pin portion 32, as shown in FIGS. As shown in FIG. 4, the engagement flange 36 is preferably formed to extend slightly downward from the clip body 30 side. With this engagement flange 36, the pin portion 32 can be elastically inserted into the clip mounting hole 18 of the holding member 14, and the clip 28 can be prevented from being loose after insertion.

As shown in FIG. 4, the holding member 14 has an axle housing 2A so that the pin portion 32 of the clip 28 can pass through the clip mounting hole 18.
And at least a gap S (see FIG. 4) large enough to allow the flange portion 32b of the crack pin 32A to enter, and is arranged so as to float from the axle housing 2A. In this case, the interval S may be provided by the height of the bolt 22 that supports the both ends 14a of the holding member 14 or the thickness of the bracket 20 itself.
When it is directly attached to the holding member 14 (of course, in other cases as well), the holding member 14 may be formed so that portions other than both ends 14a are raised.

In the illustrated embodiment, the pin portion 32 is a broken pin 32A. However, the present invention is not limited to this. If the pin portion 32 can be detachably attached by simply inserting it into the holding member 14, It can also be in the form of For example, as shown in FIG. 5, a press-fit pin 32B that can be removably inserted into the clip mounting hole 18 of the holding member 14 by press-fitting may be used. In this case, as shown in FIG. 5A, the holding member 14 may be provided with a certain thickness and inserted so as to embed the press-fit pin 32B. Alternatively, as shown in FIG.
The press-fit pin 32 </ b> B may be inserted so as to penetrate the holding member 14. In the case shown in FIG.
It is not always necessary to provide the space S (see FIG. 4) between the holding member 14 and the attached body 2.

As shown in FIG. 6, the key 40 is made to correspond to the key groove 38 by using the clip mounting hole 18 having the key groove 38 and the pin 32C having the key 40 corresponding to the key groove 38. After passing the pin 32C through the clip mounting hole 18 while rotating the clip 28, the key 40 is engaged with the lower surface 14b of the holding member 14, and the clip 2
8 can also be held.

As can be seen from the above description, according to the present invention, welding 26 is performed only on both ends 14a of the holding member 14, and the pin portion 32 of the harness support member 12 is welded to the holding member 14 without welding. By simply inserting the wire harness 1 into the clip mounting hole 18 of the holding member 14, the wire harness 1 can be attached to the axle housing 2 </ b> A
Since the wire harness 1 can be attached, the process of attaching the wire harness 1 is simplified, and labor and cost can be reduced.

The clip 28 serving as the harness support member 12 can be fixedly attached to the holding member 14 only by inserting the pin portion 32 into the clip attachment hole 18 of the holding member 14 instead of tightening with the nut 24. As a result, the harness support member 12 does not rotate with the nut 24.

Next, another embodiment of the present invention will be described.
This will be described with reference to FIGS. In this embodiment, as shown in FIG. 8, a plurality of harness support members 12 that support the wire harness 1 to be attached to the axle housing 2A, which is the attached body 2, at intervals.
1 to 6 with respect to the point that the holding member 14 is attached to the axle housing 2A with both ends 14a fixed thereto and holds a plurality of harness support members 12.
This is the same as the embodiment shown in FIG.

In this embodiment, however, as shown in FIG. 8, the harness support member 12 can be used while reducing the labor and cost while using a sheet metal clip 42 conventionally used as the harness support member 12. This is to prevent them from rotating together. Accordingly, in this embodiment, the sheet metal clip 42 as the harness support member 12 is fastened to the holding member 14 by a fastening member 44 including, for example, the bolt 22 and the nut 24, as shown in FIGS. Is held.

More specifically, in this embodiment, as shown in FIG. 7, the holding member 14 is
A clip holding portion 14 having a clip mounting hole 18 formed to protrude from the holding member 14A corresponding to a holding position of the sheet metal clip 42 as the harness support member 12.
B, and a detent portion 46 is formed in the clip holding portion 14B as shown in FIGS.

As shown in FIGS. 8 and 9, the detent portion 46 is formed so as to extend upward from one end of the clip holding portion 14B, and engages with the sheet metal clip 42 as the harness support member 12. Consists of mating side walls 46A. Therefore, as shown in FIG. 9, when the sheet metal clip 42 is fastened, the rotation preventing portion 46 particularly
6A is engaged with the sheet metal clip 42 that is about to rotate in the rotation direction of the nut 24, and restricts and suppresses the rotation of the sheet metal clip 42. For this reason, the harness support member 1
2, the sheet metal clip 42 does not rotate together.

It should be noted that, from this, this detent portion 46
As shown in FIGS. 7 to 9, the side wall 46A must be formed in the rotation direction of the nut 24 with respect to the sheet metal clip 42 (the direction in which the sheet metal clip 42 tries to rotate together with the nut 24). , Clip holder 14
It can be seen that it is sufficient to form the nut 24 only in the rotation direction of the nut 24, not on both sides. Also, as described above, the side wall 46A
If only one end of the clip holding portion 14B is provided, co-rotation can be prevented, and at the same time, the side wall 46A does not hinder the tightening of the nut 24, and the weight can be reduced. it can. However, nut 2
4 may be formed on both sides of the clip holding portion 14B as long as a sufficient space or the like for tightening the nut 4 can be secured. In this case, regardless of the rotation direction of the nut 24,
The co-rotation of the sheet metal clip 42 can be more reliably prevented. Note that the mounting direction of the sheet metal clip 42 is not limited to the direction shown in FIGS. 7 to 9, but may be any other appropriate direction if the co-rotation of the sheet metal clip 42 can be prevented in relation to the rotation preventing portion 46. It goes without saying that it can be set. Also, the height of the side wall 46A, which is the rotation preventing portion 46, may be set to be at least higher than the thickness of the sheet metal clip 42 so that the side wall 46A can be engaged with the sheet metal clip 42 to prevent co-rotation.

In this case, it should be noted that the side wall 46A, which is the anti-rotation part 46, is, as shown in FIGS.
That is, a part of the holding member 14 (clip holding portion 14B) is formed integrally with the holding member 14 by bending and cutting the portion with a press machine or the like. Therefore, as in the prior art shown in FIG.
Since the sheet metal clip 42 serving as the harness support member 12 can be prevented from rotating around without welding other parts such as the above, labor and cost can be reduced by reducing a troublesome welding process. This is made possible because the sheet metal clip 42 is attached to the attached body 2 via the holding member 14 in the present invention. It is to be noted that an increase in weight can be suppressed as compared with a case where separate components such as the rotation preventing component 50 are individually welded to the holding member 14.

Of course, also in this embodiment, since the sheet metal clip 42 is held by the holding member 14, the bolt 42 is used to attach the sheet metal clip 42, which is the harness support member 12, to the object 2 without the interposition of the holding member 14. Unlike the prior art, in which the bolts 22 have to be directly welded to the body 2 at a number of locations, the bolts 22 do not necessarily need to be welded to the holding member 14, and the reduction in the number of welding steps saves labor and cost. There is an advantage that it can be reduced as in the embodiment shown in FIGS.

It is to be noted that the sheet metal clip 42 is formed into a shape having a support ring 34 by rounding and processing an end of a thin plate-shaped material with a sheet metal, as is generally known. As shown in FIG. 9, a bolt through-hole 42a is formed in the sheet metal clip 42. Sheet metal clip 42
As shown in FIG. 9, after aligning the bolt through hole 42a with the clip mounting hole 18 of the holding member 14, the bolt 22 is passed through both holes from below, and an impact wrench or the like is inserted from above. Thus, it is held by the clip holding portion 14B of the holding member 14 by tightening with the nut 24. Therefore, also in this embodiment, as shown in FIG. 9, the bolt 22 is large enough to dispose the bolt 22 between at least the clip holding portion 14B of the holding member 14 and the axle housing 2A as the attached body 2. It is necessary to provide an interval S (see FIG. 9).

In this case, as shown in FIG. 9, the bolt 22 is passed through the clip mounting hole 18 formed in the clip holding portion 14B, and then welded to the lower surface 14b of the clip holding portion 14B of the holding member 14 in advance. It may be fixed and attached by 26 or the like. Even in this case, in the prior art shown in FIG. 12, when the sheet metal clip 42 is used and the detent component 50 is to be installed at the same time, it is necessary to weld both the bolt 22 and the detent component 50. In comparison, the workability is remarkably good in that it is not necessary to weld the detent components 50 individually to each bolt 22 and the like, and the welding of the bolt 22 itself is the same as in the prior art. Can be performed in advance of the mounting of the holding member 14 or before the holding member 14 is fixed to the axle housing 2A, and the holding member 14 is easier to handle as a single unit than the axle housing 2A. Can be performed in a wide space, and thus can be performed more easily than when welding is directly performed to the axle housing 2A.

[0040]

According to the present invention, as described above, the harness support member can be attached to the object to be mounted via the holding member, and the harness support member can be removably inserted into the mounting hole of the holding member. Since a clip having a pin portion such as a broken pin is used, it is sufficient to perform welding only at both ends of the holding member, and simply insert the pin portion into the clip mounting hole of the holding member without welding the harness support member to the holding member. Since the wire harness can be attached to the body to be attached, the process of attaching the wire harness is simplified, and there is a benefit that the labor and cost can be reduced.

Further, according to the present invention, the clip serving as the harness support member can be fixedly attached to the holding member only by inserting the pin portion of the clip into the clip mounting hole of the holding member instead of fastening with the nut. Therefore, there is a benefit that the work of attaching the wire harness can be facilitated without the harness support member rotating with the nut.

Further, according to the present invention, as described above, since the harness support member fixed by tightening the bolts and nuts is held by the holding member, the harness support member can be covered without passing through the holding member. Unlike the prior art, in which bolts had to be welded directly to the body to be mounted at many locations to be mounted on the mounting body, it is not necessary to weld the bolts to the holding member, and a part of the holding member is bent. To form a detent part,
Since it is possible to prevent the harness support member from rotating together without welding another part for preventing rotation, labor and cost can be reduced, and the harness support member does not rotate together, so that the wiring harness In addition to the benefit of facilitating the mounting work, there is also the benefit of suppressing an increase in weight as compared with a case where separate parts such as detent components are individually welded to the holding member.
