Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector that regulates and protects a wire harness routed to an automobile, and particularly, a branch line of the wire harness is taken out from the middle of the protector, and the branch line is attached to a vehicle body. It allows adjustment of the length of the branch line in the case of being clipped to.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a wire harness (engine room harness) W / H arranged in an engine room of an automobile is a dash panel for partitioning an engine room (X) and a vehicle room (Y). A grommet G is attached to a portion through which the through hole H of P passes, and a relatively long protector 1 is installed near the engine room side of the grommet G.

In the wire harness W / H, a trunk line W2 connected to a relay box (not shown) is branched from a trunk line W1 of the wire harness W / H which penetrates the protector 1 having a concave cross section. This branch line W2 is the protector 1
Tape 3 to tape winding tongue 1b protruding from side wall 1a
It is wrapped around and pulled out. The protector 1 is provided with a clip portion 1d for locking the vehicle body from a bottom wall 1c of the protector 1, and a clip 4 for locking the vehicle body is attached to a branch line W2 drawn from the protector 1.

When the wire harness W / H is installed in the engine room, the grommet G is first attached and fixed to the dash panel P, and then the clip portion 1 of the protector 1 is attached.
d is inserted and locked in the locking hole formed in the vehicle body, and then the clip 4 attached to the branch line W2 is inserted and locked in the locking hole of the vehicle body.

[0005]

Since the branch line W2 is fixed to the tape winding tongue 1b of the protector 1 with the tape 3, the branching dimension is likely to shift, and the clip portion 1d of the protector and the clip 3 of the branch line W2 are easily displaced. The dimension of is easier to shift than the design dimension. If the above dimension is shorter than the design dimension, it cannot be inserted and locked in the locking hole that is preliminarily drilled in the vehicle body. Therefore, in many cases, the branch line W2 has an extra length so that the above dimension is larger than the design dimension.
However, if the branch line W2 has an extra length, there is a problem that interference with peripheral parts occurs and the branch line W2 is easily damaged.

Further, since the branch line W2 is fixed by winding the tape 3 around the tape winding tongue 1b of the protector 1,
The branch line W2 is not flexible and the vehicle assembly is poor. Further, when the wire harness W / H is assembled to the protector 1, both ends of the trunk line W1 are fixed by winding the tape winding 3'on the tape winding tongues 1e and 1f projecting from both ends in the length direction of the bottom wall of the protector 1. At the same time, since the branch line W2 is fixed by winding the tape 3 around the tape winding tongue 1b protruding from the side wall 1a as described above, there is a problem that it requires a lot of work.

The present invention has been made in view of the above-mentioned problems, and the branch line has a surplus length so that the dimension between the clip position of the protector and the clip position of the branch line can be adjusted, and the branch line is attached to peripheral parts. Avoid interference, and
An object of the present invention is to improve the performance of assembling a wire harness having the branch line to a protector and the performance of installing the branch line.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to fix a wire harness through a protector body having a concave cross-section to a vehicle body and to extend the wire harness from the middle of the protector body. In the protector for the wire harness used for pulling out the branch line branching from the trunk line to the outside and for clipping the pulled-out branch line to the vehicle body, partially close the upper opening of the protector body that hits the branch line branch position. With a lid,
A movable space of a branch line is formed between the lid and the protector body, and after bending a branch line branched from the main line inside the movable space, the tip of the lid is diverted to the outside of the branch line. There is provided a protector for a wire harness in which a branch line bent inside the movable space can be pulled out in accordance with the clip position of the branch line to adjust the clip position attached to the branch line.

The lid is integrally formed with a thin hinge from the tip of one side wall of the protector body, and is fixed by a lock mechanism provided between the lid and the protector body when closed. The lid is closed after the wire harness is penetrated inside the protector body, and the branch line is pulled outward through the upper surface opening of the protector body which is not closed by the lid, so that the branch line extends between the lid and the protector body. It is bent in the movable space, bypasses the line of the lid, and is drawn outward.

As described above, the protector body is partially provided with a lid at a position where the branch line is pulled out, and a movable space for the branch line is formed between the lid and the bottom wall of the protector body with an extra length. ing. Since the extra length of the branch line is bent and stored in this movable space and the tip of the lid is circumvented from the bent part to pull out the branch line to the outside, when the branch line is clipped to the vehicle body, the vehicle body is locked. The branch line can be pulled out from the protector to a position that fits the hole. Therefore, an unnecessarily long branch line portion can be kept in a state of being housed in the movable space of the protector body, and it is possible to prevent the branch line from interfering with peripheral parts and being damaged.

Further, since the branch line is not wrapped around the protector with tape, it has flexibility, so that it is possible to enhance the workability of wiring to the vehicle body, and when the wire harness is assembled to the protector, only the trunk line is wrapped around the protector with tape. Since it suffices to fix it and the tape winding of the branch line is unnecessary, the number of work steps can be reduced and the assembling performance can be improved.

[0012] It is preferable that, in the branch line, only a portion to be bent in the movable space between the lid and the bottom wall (branch root portion of the branch line) is formed by winding the wire group constituting the branch line by tape winding. Other than the above, the branch lines are not wrapped by tape. In this way, if the branch lines are converged by tape winding only in the part that is bent in the movable space, the branch lines will not come apart and the other parts will not be wound with tape, so the flexibility of the branch lines can be maintained. it can.

Alternatively, in the branch line, only a portion to be bent in the movable space between the lid and the bottom wall is bundled by winding a wire group constituting the branch line with a trunk line and tape winding, and the bundled tape is pulled by the branch line. It is set to stretch. Specifically, the tape is wound around once, and when the branch line is pulled, the vinyl chloride tape extends to allow the branch line to be pulled out. In this way, if the branch line of the extra length part is tape-wound with the main line, the branch line can be held flat, the height of the protector can be suppressed, the tension of the branch line to the lid can be relaxed, and the protector The thickness can be reduced.

An elastic adjusting plate for adjusting the length of the branch line is projectingly provided by cantilever support on the inner surface of the lid, and the movable space is provided between the elastic adjusting plate and the bottom wall of the protector body when the lid is closed. A structure in which the branch line is bent in the movable space, the free end of the elastic adjustment plate is bypassed and drawn outward, and the branch line is drawn according to the clip position of the branch line to displace the elastic adjustment plate. Is preferred.

Specifically, the elastic adjusting plate is substantially U-shaped in a plan view, the ends of both sides thereof are bent upward to be fixed to the lid, and the both sides extend in the length direction of the main line. The connecting portion is a free end, and the fixing position to the lid is above the branching position of the branch line, depending on the pulling force of the branch line that is brought into contact with the free end of the elastic adjustment plate and is drawn outward. The free end is vertically displaced from the fixed position of the lid as a base point.

As described above, when the elastic adjusting plate for pressing the branch line is provided on the inner surface of the lid, the extra length portion of the branch line which is bent and stored in the movable space between the lid and the bottom wall has the elasticity. It is pressed and held by the adjusting plate, and the branch line can be pulled out from the protector by the required size. Therefore, it is possible to prevent the branch line from accidentally coming out of the protector, and it is possible to reliably prevent damage to the branch line. Further, since the branch line can be held in the original position by the elastic adjustment plate, it is not necessary to bind the branch line with tape, and the number of working steps can be further reduced.

A step portion 11g is provided between the lid 12 and the lid 13 on both side surfaces of the horizontal arrangement portion 11f so that the installation position of the lid 12 is higher than the installation position of the lid 13. The bottom wall 11h is provided with an extending portion 11d at the end opposite to the rising portion 11a.
Clip attachment grooves 11d-1 are cut out on both sides of 1d.

As shown in FIG. 3, the wire harness W / H
The main line w1 is hung from the horizontally arranged portion 11f of the protector body 11 having a concave cross-section to the rising portion 11a and inserted, and the lids 12 and 13 are closed and locked. The branch line w2 branched from the main line w1 is bent inside the movable space S formed between the lid 12 and the protector body 11, and then the lid 12
The clip 14 is led out upward from the opening between the rising portion 11a and the rising portion 11a, and the clip 14 is wound around a required position. Further, the branch line w2 is a portion to be bent in the movable space S between the lid 12 and the bottom wall 11h, that is, an extra length portion w2a.
In, the electric wire group forming the branch line w2 is wound around the tape T.

A band clip 16 is wound around the clip mounting groove 11d of the extending portion 11d together with the main wire w1. The clip portion 11e of the protector 10 is provided in the locking holes H1 and H2 which are pre-drilled in the vehicle body P1. By inserting and locking the clips 16 respectively, the protector 10 is fixed to the vehicle body P1 together with the wire harness W / H.

By providing the stepped portion 11g on the protector body 11, a movable space S having a branch line w2 is formed between the lid 12 and the protector body 11 in a state where the lid 12 is closed. Since the extra length portion w2a is bent with a space, the branch line w2 can be pulled out in the vertical direction as shown by the arrow in FIG. 3, and the position of the clip 14 attached to the branch line w2 can be adjusted in the vertical direction. You can

Therefore, the clip 14 of the branch line w2 is attached to the vehicle body P.
When clipped to the locking hole H3 of No. 2, the branch line w2 can be pulled out from the protector 10 to a position matching the locking hole H3 of the vehicle body P2. At the same time, the unnecessarily long branch line w2 is the movable space S of the protector body 11.
Can be left in the state that it is stored in the branch line w2
Can be prevented from interfering with peripheral parts and causing damage.

Further, since the branch line w2 is not wound with the tape T around the protector 10, the branch line w2 has flexibility, so that the workability of arranging on the vehicle body P2 can be improved and the wire harness W is also provided.
When assembling / H to the protector 10, it is sufficient to fix only the trunk line w1 to the protector 10 with a tape T, and the branch line w
Since the second tape winding is unnecessary, the number of work steps can be reduced and the assembling performance can be improved.

Furthermore, the lid 12 and the bottom wall 11 of the branch line w2.
Only the portion to be bent in the movable space S between h (the branch root portion of the branch line w2) focuses the electric wire group forming the branch line w2 with the tape T winding, and the branch line w2 with the tape winding in the other portions. Since the branch line w2 does not come apart and the other part is not wound with tape, the flexibility of the branch line w2 can be maintained.

FIG. 5 shows a second embodiment. The difference from the first embodiment is that only the portion of the branch line w2 that is bent in the movable space S between the lid 12 and the bottom wall 11h is bundled with the main line w1 by the tape T winding of the wire group forming the branch line w2. That is the point.

The focusing tape T is made of an elastic material such as vinyl chloride, and the number of windings is about one. With the above configuration, when the branch line w2 is pulled, the tape T extends and the branch line w2 can be pulled out. In this way, if the extra length w2a of the branch line w2, the main line w1, and the tape T are wound, the branch line w2 can be held in a flat state, the height of the protector 10 can be suppressed, and the branch line w2 to the lid 12 can be suppressed. The tension can be relaxed and the thickness of the protector 10 can be reduced. Note that the other configurations are similar to those of the first embodiment, and thus the description thereof will be omitted.

FIGS. 6A, 6B and 6C show the third embodiment. The difference from the first embodiment is that an elastic adjusting plate 12b 'is projectingly provided by cantilever support on the inner surface of the lid 12' of the protector 10 '.

The elastic adjusting plate 12b 'has a substantially U shape in plan view, the tips of both side portions 12b-2' are bent upward, and the tip portions 12b-3 'are integrally connected to the inner surface of the lid 12. At the same time, both side portions 12b-2 'extend in the length direction of the trunk line w1 and the connecting portion 12b-1' is a free end. Further, the fixing position of the elastic adjusting plate 12b 'to the lid 12 is above the branch position of the branch line w2, and the elastic adjusting plate 12b' is fixed.
The free end 12b-1 'is configured to be displaced up and down with respect to the fixed position of the lid 12 as a base point in accordance with the pulling force of the branch line w2 that is brought into contact with the free end 12b-1' and is drawn outward.

With the above structure, since the branch line w2 can be pulled out, the position of the clip 14 can be adjusted in the vertical direction, the clip 14 can be easily attached to the locking hole of the vehicle body, and the dimension between the locking holes can be adjusted. It will not be installed due to error. Further, if an elastic adjusting plate 12b 'for pressing a branch line is provided on the inner surface of the lid 12, the lid 12' and the bottom wall 1

2 can be prevented from coming out of the protector 10, and the occurrence of damage to the branch line w2 can be reliably prevented. Further, since the branch line w2 can be held in the original position by the elastic adjusting plate 12b ', the tape winding bundling of the branch line w2 can be eliminated, and the number of working steps can be further reduced.

[0030]

As is apparent from the above description, according to the present invention, the protector body is partially provided with a lid at a position where the branch line is pulled out, and the protector body is movable between the lid and the bottom wall of the protector body. The extra length of the branch line is bent and stored in the space, and the branch line is pulled out to the outside by bypassing the tip of the lid, so when clipping the branch line to the vehicle body, the branch line should be fitted to the position where it fits into the locking hole of the vehicle body. Can be withdrawn.

Further, by keeping the unnecessarily long branch line part accommodated in the movable space, it is possible to prevent the damage from being caused by interfering with the peripheral parts. Further, since the branch line is not wrapped around the protector with the tape, but only the trunk line is wrapped around the protector with the tape, the work man-hours can be reduced and the assembling performance can be improved as compared with the conventional case.

Alternatively, only the portion of the branch line that is bent in the movable space between the lid and the bottom wall is bundled with the main line by tape winding, and the bundled tape is set to extend when the branch line is pulled. Also, when clipping the branch line to the vehicle body, the branch line can be pulled out to a position that fits into the locking hole of the vehicle body, and the height of the protector can be suppressed by holding the branch line in a flat state, and the branch line to the lid It is possible to relieve the tension and to make the protector thin.

Alternatively, if an elastic adjusting plate for pressing the branch line is provided on the inner surface of the lid, the elastic adjusting plate allows the extra length of the branch line to be bent and stored in the movable space between the lid and the bottom wall. Since the branch line is pressed and held and can be pulled out from the protector by the required size, when the branch line is clipped to the vehicle body, the branch line can be pulled out to a position that fits into the locking hole of the vehicle body, and the branch line is inadvertently It is possible to prevent it from coming out of the branch, and it is possible to reliably prevent damage to the branch line. Further, since the branch line can be held in the original position by the elastic adjustment plate, it is not necessary to bind the branch line with tape, and the number of working steps can be further reduced.
