And
The position of the vehicle body 3 to be mounted is generally a place with poor mounting conditions, such as a narrow place under the cab or a side or back of equipment, so that mounting work is troublesome and easy. There were many problems in work efficiency. Second, there is a problem that the wiring harness 1 is easily damaged. That is, the wiring harness 1 has a problem that the wiring harness 1 is attached to the middle by the clamp 2 but is mostly exposed to the outside, so that the protection is insufficient and the wiring harness 1 is easily damaged during or after the mounting operation. Was.

The present invention has been made in view of the above circumstances and has been made to solve the above-mentioned problems of the conventional example. A wiring harness is housed in a housing body from an insertion cut and is attached to a vehicle body. An object of the present invention is to propose a mounting structure of a wiring harness in which a support is fitted into an engagement groove portion of a storage body, thereby first simplifying an installation work and secondly preventing damage.

[0005]

The technical means of the present invention for achieving this object is as follows. That is, the mounting structure of the wiring harness in this vehicle includes the following support and housing. That is, the wiring harness corresponds to the route of the wiring harness arranged with the vehicle body side as an attachment target, has a total length corresponding to the route, and is bent and bent to match the route. It comprises a rigid support made of a rigid material attached to the vehicle body, and a flexible material storage body having a substantially tubular shape and containing the wiring harness therein. In addition, an insertion cut for accommodating the wiring harness is formed in the storage body over the entire length, and an engagement groove portion in which the support is fitted and engaged from outside is formed. The insertion cut can be widened so that the wiring harness can be inserted into the housing. The engaging groove is formed in a concave shape with respect to the storage body, has a cross-sectional shape corresponding to the support, and has a narrow neck, and the support is pressed against the neck from outside.

That is, first, the mounting structure is divided into a support body and a storage body. In order to cope with the mounting conditions such as the position of the vehicle body to be mounted, the above-mentioned mounting method can be appropriately selected from the former and the latter, and the mounting operation is facilitated. Similarly, the mounting structure is divided into a rigid support and a flexible housing. First, the length corresponding to the route of the vehicle body to be attached, the curvature,
The support made of a rigid material having a bend or the like is securely fixed to the vehicle body by a bracket. On the other hand, since the storage body is made of a flexible material, it is easy to insert and engage such a support body and to store the wiring harness.
It can easily follow the curved or bent path later, and the applied force is absorbed. As described above, since the mounting structure is divided into the support made of the rigid material and the storage body made of the flexible material, the mounting operation is facilitated. The bracket used for attaching the support to the vehicle body holds the support made of a rigid material. Therefore, a relatively small number is required at intervals as compared with a conventional example of this type having a fine pitch.
The position on the vehicle body side to be mounted is generally a place where mounting conditions are poor, such as a narrow place or a side surface or a back surface of the equipment. However, as described above, the number of brackets is small. Installation work is simplified by that much. Furthermore, the wiring harness can be easily stored in the storage body by temporarily expanding the insertion cut of the storage body, inserting and inserting the wiring harness. The support is
By pressing and fitting into the neck of the engaging groove of the storage body, the storage body is easily and irretrievably engaged with the storage body. Also from these aspects, the mounting operation is facilitated without taking much time. Second

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. FIG. 1 is an exploded perspective view of a main part of an embodiment of the present invention, FIG. 2 (1) is a perspective view of the main part of the embodiment, and FIG. 2 (2) is a front sectional view of the same.

[0008] Wiring harness 1 in this vehicle
Is provided with the following support 6 and storage 7. First, the wiring harness 1 is, for example, an instrument panel 4 (see FIG. 3) of a cab on the vehicle body 3 side.
It is composed of a connection portion in which various wirings, cables, fibers, and the like between various electric components such as a meter, a lamp, a heater, a cooler, and a car stereo and a battery power source are bundled in the middle. The wiring harness 1 is arranged, for example, between the vicinity of the instrument panel 4 and the floor of the driver's seat 5 along the equipment of the vehicle body 3 (see FIG. 3). The support body 6 corresponds to the path of the wiring harness 1 arranged with the vehicle body 3 side as the mounting target, and has a length corresponding to such a path, and has a curved shape corresponding to such a path. It is bent. The support 6 is attached to the vehicle body 3 via a plurality of brackets 8. Support 6 in the illustrated example
Is made of a pipe-shaped rigid material, and brackets 8 are erected at regular intervals. The brackets 8 are screwed to nuts 10 that are passed through holes in bolts 9 and welded to a sheet metal or the like on the vehicle body 3 side. By being combined, it is fixed to the vehicle body 3. In addition, the shape of the support 6 may be various shapes other than the illustrated example.

Next, the housing 7 has a substantially cylindrical shape, can house the wiring harness 1 therein, and is made of a flexible material. That is, the housing 7 is made of, for example, a resin bristle material, has flexibility and elasticity, facilitates the housing of the wiring harness 1, and has the vehicle body 3.
When the wiring harness 1 is attached to the wiring harness 1, the wiring harness 1 can easily follow a curved or bent path, and can absorb a force applied at that time. Since the housing 7 has a substantially tubular shape and the wiring harness 1 is housed in a hollow portion inside, the insertion cut 11, which is a crack for housing the wiring harness 1, is formed linearly over the entire length. The wiring harness 1 temporarily widens the insertion cut 11,
It is inserted into the housing 7. Further, the housing 7 is formed with an engagement groove 12 into which the support 6 is fitted and engaged from the outside. The engaging groove 12 is formed in a concave shape on the opposite side to the insertion cut 11 over the entire length of the support 6 and has a cross-sectional shape corresponding to the support 6, and the support 6 is formed on the narrow neck portion from the outside. As a result, the support 6 is fitted into the engagement groove 12 and is engaged so that it cannot be pulled out.

The mounting structure of the wiring harness 1 in a vehicle according to the present invention is configured as described above, and is as follows. In this mounting structure, the wiring harness 1 is mounted by any of the following mounting methods. In the former mounting method, first, the wiring harness 1 is inserted and stored in the storage body 7 from the insertion cut 11, and the support body 6 is fitted and engaged in the engagement groove 12 of the storage body 7. Thereafter, the support 6 is attached to the vehicle body 3 using the bracket 8. On the other hand,
In the latter mounting method, first, the wiring harness 1 is inserted and stored in the storage body 7 from the insertion cut 11, and the support body 6 is mounted on the vehicle body 3 by using the bracket 8. By pressing the support 7 against the support 6, the support 6 is fitted into and engaged with the engagement groove 12 of the housing 7.

Then, in this mounting structure, the following first and second cases will be described. First, the mounting operation is simplified and facilitated. First, the mounting structure is divided into a support body 6 and a storage body 7, and any one of the above mounting methods can be appropriately selected according to mounting conditions such as a position on the vehicle body 3 side to be mounted. Work is facilitated. The bracket 8 used to attach the support 6 to the vehicle body 3 does not directly hold the wiring harness 1 like the clamp 2 (see FIG. 3) of the conventional example, but holds the support 6. Therefore, a relatively small number can be provided at intervals as compared with the conventional clamp 2. In addition, since the number of the brackets 8 can be reduced in this way, it is generally considered that the mounting condition is poor, such as the position on the vehicle body 3 side to be mounted is narrow and the side and rear surfaces of the equipment. Accordingly, the mounting operation is simplified. Furthermore, the wiring harness 1 is stored in the storage body 7 by insertion, and the support body 6 is engaged with the storage body 7 by fitting, so that the mounting operation is also facilitated from this surface. Second, since the wiring harness 1 is stored and protected in the storage body 7, damage is prevented during and after the mounting operation.

[0012]

As described above, the mounting structure of the wiring harness in the vehicle according to the present invention is such that the wiring harness is housed in the flexible housing from the insertion cut and the rigid material is attached to the vehicle body. The following effects are exerted by having the support made of steel fit into the engagement groove of the housing. First, the work of attaching the wiring harness is simplified and facilitated. That is, first, the mounting structure is divided into a support body and a storage body, and a mounting method can be selected. , Storage and the like are easy, and it is easy to follow the path and absorb the force. Also, a relatively small number of brackets may be used at intervals, and the brackets may be mounted by insertion or engagement by insertion. Based on the above, the mounting work can be simplified and simplified without troublesome work, and the work efficiency is improved. Second, damage to the wiring harness is prevented. That is, since the wiring harness is stored in the storage body, the wiring harness is sufficiently protected during and after the mounting operation, and the damage is reliably prevented.
As described above, the effects exhibited by the present invention are remarkably large, for example, the problems existing in this kind of conventional example are eliminated.
