Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a half-split corrugated tube to a wire harness.
The half corrugated tube attached to the wire harness is attached along a predetermined direction of the wire harness without being twisted.

[0002]

2. Description of the Related Art Cylindrical corrugated tubes are attached to a wire harness routed along the body of an automobile as an exterior protective material. May be enough.
In that case, as shown in FIG. 4, a half-corrugated tube 1 having a semi-annular cross-sectional shape in which a cylindrical corrugated tube is vertically divided along the axial direction is taped on the outer peripheral surface of the wire harness W / H. It is wound around and attached.

Further, when the clamp 3 is mounted to fix the wire harness W / H to a predetermined position on the vehicle body, usually, the half-corrugated tube 1 is used.
Is mounted on the clamp mounting side, and as shown in FIG.
Is attached with a tape 4.

[0004]

When the above-mentioned half-corrugated tube 1 is put on a half-periphery portion of the outer peripheral surface of the wire harness W / H, its position is not regulated, and therefore it is easy to move in the direction of the arrow as shown in FIG. It is difficult to determine the mounting position of the corrugated tube 1. Therefore, when the tape 2 is wound as shown in FIG. 4, the position of the corrugated tube 1 may be shifted.

In order to eliminate the displacement of the half-split corrugated tube 1 and keep it in a predetermined direction as much as possible, as shown in FIG. 7, an operator presses the corrugated tube 1 with one hand to prevent the displacement. Then, the tape 2 is wrapped with the other hand, thereby reducing the displacement.

However, since it is performed manually,
The displacement of the corrugated tube cannot be reliably prevented. If the displacement occurs, the corrugated tube does not exist at the position to be protected by the corrugated tube, and the interference member may damage the wire harness. Further, when a position shift occurs in the corrugated tube 1, a clamp 3 to be attached to the outer surface of the corrugated tube 1 is provided.
May be directly attached to the outer peripheral surface of the wire harness W / H.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and enables a half-corrugated tube to be mounted at a predetermined position of a wire harness without displacement, and a half-corrugated tube to be securely positioned at a clamp mounting position. The task is to make it happen.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a clamp extraction hole at a predetermined position of a half-split corrugated tube exteriorly provided on a wire harness, and a vehicle body locking device previously attached to the wire harness. A corrugated tube mounting structure for a wire harness is provided, in which a body engaging portion of a clamp for a vehicle protrudes from the clamp extraction hole, and the half corrugated tube is mounted on the wire harness.

[0009] The clamp extraction hole formed in the corrugated tube has a size for forcibly inserting the vehicle body locking portion of the clamp, and the half body corrugated tube is inserted into the wire harness by passing the vehicle body locking portion through the clamp extraction hole. It is set to be fixed. In addition, after making the above-mentioned clamp removal hole a size that allows the vehicle body locking portion of the clamp to easily pass through, and after passing the vehicle body locking portion through the clamp removal hole,
The half-split corrugated tube and the wire harness may be fixed by tape winding.

[0010] The clamp may be a board-type clamp in which a board portion on which a vehicle body locking portion is projected is attached to a wire harness by tape winding, or a band-type clamp in which a band is wound around a wire harness and fastened and fixed. May be.

The method for mounting the clamp and the half-corrugated tube on the wire harness is as follows. First, on a wire harness assembling work table, the wire harness is installed at a predetermined position on a group of electric wires laid along a wiring jig. Attach the clamp using a clamp jig. At this time, since the clamp jig is installed on the assembly worktable so as to attach the clamp to a predetermined position on the outer periphery of the wire harness, the clamp is always attached to the predetermined position of the wire harness. Next, a half-split corrugated tube having a clamp extraction hole at a predetermined position is applied to the outer peripheral surface of the wire group. At that time, by applying to the wire group so that the vehicle body locking portion of the clamp previously attached to the wire harness is protruded from the clamp extraction hole, the vehicle body locking portion is forcibly inserted into the clamp extraction hole to protrude. The half corrugated tube is fixed to the wire harness by the protruding vehicle engaging portion.

As described above, the half-corrugated tube can be attached to the wire harness at the predetermined position without twisting by a one-touch operation of merely passing the clamp extraction hole of the half-corrugated tube through the clamp previously mounted at the predetermined position. Can be. As a result, it is not necessary to wind the tape while holding down the half-split corrugated tube so as not to be displaced, and the workability can be improved. In addition, the clamp is always attached at a position where the wire group is protected by the half corrugated tube.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a board-type clamp 10 is attached to a predetermined position of the wire harness W / H, and a half-corrugated tube 11 is attached outside the clamp 10.

The half-corrugated tube 11 has a semi-annular cross-section, and is provided at a predetermined position in the axial direction.
1a is opened. The clamp removal hole 11a is set to have a size that allows the vehicle body locking portion 10a of the clamp 10 to be forcibly inserted. That is, the substrate unit 1 of the clamp 10
0b, the locking blade 10a-2 protrudes from the shaft 10a-1, and the locking blade 10a-2 is bent and inserted into the clamp extraction hole 11a. After the insertion, the locking blade portion 10a-2 returns to its original state,
It is set so as to hold down the periphery of the clamp extraction hole 11a and prevent the half-corrugated tube 11 from falling off.

As shown in FIG. 2, the method of attaching the clamp 10 and the half-split corrugated tube 11 to the wire harness W / H is as follows, along a wire receiving jig on a wire harness assembly work table (not shown). Wire group W wired
First, the tape T1 is wound in a rough winding and bound.
Next, a clamp 1 is placed in a predetermined position in the axial direction of the wire group W and in a predetermined direction of the wire group W by a clamp mounting jig (not shown) which is erected at a predetermined position on the assembly work table.
0 is applied, and the substrate 10b is fixed with the tape T2.

In this state, the half-split corrugated tube 11 is applied to the wire group W, and the clamp extraction hole 1 is provided.
1a is positioned at the vehicle body engaging portion 10a of the clamp 10.
Next, the vehicle body locking portion 10a is forcibly inserted into the clamp removal hole 11a, and protrudes from the outer surface of the half split corrugated tube 11.

The locking blade 10a-2 of the vehicle body locking portion 10a protruding from the clamp extraction hole 11a is restored to its original shape and located on the outer peripheral surface of the clamp extraction hole 11a. Halved corrugated tube 11
Are positioned and fixed to the wire group W.

As described above, the half corrugated tube 1
When attaching the wire harness W / H, which is covered in 1, to the vehicle body panel of the vehicle, as shown in FIGS. 3A and 3B, the vehicle body locking portion 10a of the clamp projecting from the half corrugated tube 11 is connected to the vehicle body. Mounting hole 20 for panel 20
is pushed in and fixed by the locking blade portion 10a-2. As described above, the locking wing portion 10a-2 of the clamp 10 is inserted and locked in the mounting hole 20a of the vehicle body panel, so that the half corrugated tube 11 passing through the locking wing portion 10a-2 is detached from the clamp 10. It becomes impossible to do. Therefore, even if the half-corrugated tube 11 is not fixed to the outer peripheral surface of the wire harness W / H by tape winding, the half-corrugated tube 11 is reliably positioned and held on the outer peripheral surface of the wire harness W / H.

When the clamp take-out hole 11a provided in the half corrugated tube 11 is enlarged to facilitate insertion of the vehicle body locking portion 10a of the clamp 10, half of the corrugated tube 11 is fixed until the wire harness is fixed to the vehicle body. Since the split corrugated tube 11 may fall out of the wire harness, it is preferable that the half-corrugated tube 11 is roughly wound around the wire harness with a tape.

Also in this case, since the half-corrugated tube is positioned by the clamp, the half-corrugated tube is not twisted when the tape is wound, and the tape winding operation can be made easier than before.

[0021]

As is apparent from the above description, according to the present invention, only by providing a clamp take-out hole in a half-split corrugated tube, a body-holding clamp attached to a wire harness can be used. The half-corrugated tube can be attached to a predetermined position with a single touch without being twisted with respect to the wire harness.
