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 wire harness on a vehicle body, and more particularly to a wire harness which can be easily installed in an automobile.

[0002]

2. Description of the Related Art Recently, the number of electrical components mounted on automobiles has increased, and along with that, the number of wire harnesses for connecting a power source and electrical components has also increased, and an extremely large number of wire harnesses must be installed in automobiles. It has become obsolete. Usually, a wire harness is formed by winding a number of electric wires and binding them together.
These wire harnesses are fixed to a mounting surface such as a vehicle body panel using a resin clamp or the like.

In addition to the wire harness in which the above-mentioned electric wires are bundled by tape winding, a copper foil punched into a circuit shape is sandwiched between insulating resin sheets on both sides of an FPC (flexible printed circuit), or arranged side by side at a predetermined interval. There is provided a flat wire harness (flat wire harness) such as an FWC (flexible wire circuit) in which both sides of the conductive wire are sandwiched by insulating resin sheets. The fixing of these flat wire harnesses (hereinafter, referred to as flat harnesses) to the vehicle body has been conventionally performed by using the actual open flat wire 6-51014.
No. 7 provided in FIG. 7 is used. The holder comprises a fixing member 4 attached to a holding hole provided in the vehicle body and a holding member 6 that is locked to the fixing member 4 with the wire harness 5 held therebetween.

[0004]

In the method of fixing the wire harness and the vehicle body panel or the like using the clamp or the holder, the harness mounting surface of the panel or the like is
Since the wire harness is projected and fixed, a large space is required on the mounting surface side of the wire harness. However, it is becoming increasingly difficult to secure a large space in an actual automobile.

Further, in the conventional method, it is necessary to perform many manual couplings such as a clamp coupling between the vehicle body panel and the wire harness and a connector coupling between the wire harness and the electric components in the automobile assembly line. Requires a great deal of labor in the assembly line. Moreover, as described above, a sufficient space for performing the work is not secured on the wire harness mounting side, which makes the work extremely difficult.

Further, when the wire harness is fixed to the vehicle body by using the clamp or the holder, the clamp and the holder which are separate members are required, and the number of parts is increased,
There is a problem that the cost becomes high and that these separate parts must be prepared in the automobile assembly line.

The present invention has been made to solve the above problems, and either a wire harness in which a group of electric wires is bound by a tape winding or a flat harness can be easily attached to a vehicle body. It is an object of the present invention to provide a vehicle body mounting structure for a wire harness that can significantly reduce the number of work steps on the line.

[0008]

In order to achieve the above-mentioned object, the present invention according to claim 1 provides a harness lane for accommodating a wire harness on a harness mounting surface of a vehicle body panel and at the side of a harness insertion opening. Provided is a wire harness vehicle body mounting structure characterized in that a projection for narrowing a harness insertion opening is provided from an end and a wire harness is accommodated and held in the guide lane.

The guide lane is formed in a groove shape from the surface of the vehicle body panel and is provided integrally with the vehicle body. (Claim 2) Alternatively, the guide lane is formed by a pair of guide plates protruding from the vehicle body surface. (Claim 3) These guide plates are provided with a pair of inverted L-shaped guide plates projecting from the vehicle body surface with a required space therebetween to form a harness accommodating portion between the guide plates, and to the inside closer to each other from the upper ends of these guide plates. The protruding piece serves as a projection that narrows the harness insertion opening.

The width of the guide lane is made wider than the outer diameter of the wire harness in the case of a round shaft-shaped wire harness and the width of the wire harness in the case of a flat harness. The width of the guide lane at the position where the protrusion is provided is made narrower than the outer diameter or width of the wire harness. (Claim 4) For example, in the case of a flat harness, it is preferable to increase the length of the protrusion.

The projection may be formed as a retaining hook having flexibility in the insertion direction of the wire harness. (Claim 5) That is, when the wire harness is a round shaft-shaped harness in which a large number of electric wire groups are bound together by tape winding, it is preferable that the protrusions be shortened in the lengthwise direction to serve as retaining tabs.

A band made of rubber or a clip made of a spring plate may be attached to the harness insertion opening of the guide lane in the width direction. (Claim 6)

The vehicle body panel having the above harness mounting surface is an interior member such as an instrument panel, a roof interior panel, a door interior panel, etc. The surface of these panels which is not visible from the room is the harness attachment surface, and these interior members are used for the vehicle. Before attaching the wire harness to the guide lane, a guide lane into which the wire harness can be inserted from the direction orthogonal to the axis is integrally formed on the harness attaching surface of the vehicle on which the wire harness is inserted and held in advance, and the harness is inserted into the guide lane. The mouth is integrally formed with a protrusion-like portion for preventing the harness fitting opening from narrowing. (Claim 7)

[0014]

According to the first aspect of the present invention, the harness mounting surface of the vehicle body panel (for example, the inner surface of the instrument panel).
When the wire harness is inserted into the guide lane from the direction orthogonal to the axis and installed, the wire harness inserted in the guide lane is held so that it will not come out of the guide lane due to the projections that narrow the harness insertion opening of the guide lane. It Thus, the wire harness can be easily attached to the vehicle body without using a separate member.

When the guide lane provided on the vehicle body panel made of resin or metal is recessed in a groove shape from the vehicle body surface as described in claim 2, no space is required for attaching the wire harness to the surface of the vehicle body panel. The wire harness can be installed in a place where it has been difficult to install the wire harness in the past. Further, when there is a wire harness installation space on the surface of the vehicle body panel, a guide lane may be provided by projecting a guide plate from the surface of the vehicle body panel as described in claim 3.

Unlike the flat harness having flexibility, when the wire harness is a hard tape winding bundle harness, the protrusion provided at the harness insertion port is shortened as described in claim 3, and preferably, As described in 5, when the flexible retaining claw is used, the wire harness can be smoothly inserted into the guide lane. On the other hand, when the wire harness is a soft flat harness, even if the length of the protrusion of the harness insertion port is increased, the insertion can be smoothly performed and the retainer can be reliably prevented.

Furthermore, when a band or a clip is bridged over the harness insertion opening as in the sixth aspect, the wire harness inserted and held in the guide lane can be reliably prevented from coming off.

Further, when the wire harness is installed in advance in the interior member such as the instrument panel as in the seventh aspect, the work of installing the harness in the automobile assembly line can be significantly reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The parts having the same configuration and operation as those of the prior art shown in FIG.

FIG. 1 shows the wire harness mounting structure of the first embodiment. When the wire harness 5 is a round shaft-shaped harness 5A in which a large number of electric wires whose core wires are covered with an insulating resin are collected and bundled by tape winding, when the harness is mounted on the inner surface of the vehicle, for example, the inner surface of the instrument panel 16, Face 16
A deep concave groove-shaped guide lane 16b into which a round shaft-shaped harness 5A can be fitted in from a direction orthogonal to the axis is integrally formed with a. The guide lane 16b may be provided on the entire surface of the harness mounting surface 16a, or may be provided only at a necessary portion, for example, a defective portion when the round shaft-shaped harness 5A projects outward from the harness mounting surface 16a. Good.

At both opening edge portions of the harness insertion opening 16c of the guide lane 16b, there are integrally formed projections which project inward and are formed by flexible retaining claws 16d, 16d in the insertion direction. Harness insertion opening 1 is formed by each retaining claw 16d.
The inner width W1 of 6c is narrower than the inner width W2 of the guide lane 16b. The retaining claws 16d correspond to the guide lanes 16b.
Need not be provided over the entire length, and may be provided partially at appropriate intervals.

With the configuration of the first embodiment, when the round shaft-shaped harness 5A is inserted into the harness fitting port 16c from the direction orthogonal to the axis, the retaining claws 16d are pressed by the round shaft-shaped harness 5A and naturally. When the round shaft-shaped harness 5A bends downward and is completely fitted into the guide lane 16b, the harness 5A naturally comes off the round shaft-shaped harness 5A and restores upward. Accordingly, the round shaft-shaped harness 5A can be easily attached to the instrument panel 16 with one touch without using a separate member. Also, each retaining claw 1
Since 6d flexes downward naturally, even a hard round shaft-shaped harness 5A can be smoothly inserted into the guide lane 16b.

FIG. 2 shows the mounting structure of the second embodiment. In the case where the wire harness 5 is a flat harness 5B having a flat plate shape, the harness mounting surface 16a, which is the inner surface of the instrument panel 16 of the vehicle, has a shallow concave groove shape into which the flat plate harness 5B can be fitted in a direction orthogonal to the axis. Guide lane 16
b is integrally molded. Similar to the first embodiment, the guide lane 16b may be provided on the entire surface of the harness mounting surface 16a, or it is not preferable that the required portion, for example, the flat harness 5B, projects outward from the harness mounting surface 16a. You may provide only in a place.

At both opening edge portions of the harness insertion opening 16c of the guide lane 16b, inwardly projecting projections 16e, 16e are integrally formed. The respective protrusions 16e for preventing the slip-off prevent the inner width W1 of the harness fitting port 16c from being narrower than the inner width W2 of the guide lane 16b. In the case of the soft flat harness 5B, the length of each of the above-mentioned retaining projections 16e is set to be longer than the length L1 (for example, about 1/4 of the inner width 2 of the guide lane 16b). deep.

According to the structure of the second embodiment, when the flat harness 5B is inserted into the harness insertion opening 16c from the direction orthogonal to the axis, the flat harness 5B is naturally bent inward by the respective retaining projections 16e, and the flat harness 5B is flattened. When the harness 5B is completely fitted into the guide lane 16b, the flat harness 5B is naturally disengaged from the respective projections 16e for preventing the slip-out and restored outward. As a result, the flat harness 5B
Can be easily attached to the instrument panel 16 with one touch without using a separate member. Further, since the flat harness 5B is naturally bent inward by the respective projections 16e for preventing the pull-out, the soft flat harness 5B can be smoothly fitted into the guide lane 16b. Furthermore, since the length L1 of each of the protrusions 16e for preventing slipping out is long, the flat harness 5B is more reliably prevented from slipping out.

FIG. 3 shows the mounting structure of the third embodiment. Second
The difference from the embodiment is that each of the protrusions 16e for preventing slipping out is partially provided in the guide lane 16b at an appropriate interval T1.

FIG. 4 shows the mounting structure of the fourth embodiment. If the wire harness 5 is a flat harness 5B,
A pair of guide plates 16f, 16f having an inverted L shape and rising upward from the left and right positions are integrally formed on the upper surface of the harness mounting surface 16a, which is the inner surface of the instrument panel 16 of the vehicle. A guide groove 16b having a shallow groove shape into which the flat harness 5B can be fitted is formed between them. The guide lane 16b formed by the pair of guide plates 16f and 16f may be provided on the entire surface of the harness mounting surface 16a as in the first embodiment, or may be provided only in a necessary place as in the second embodiment. Good.

At both opening edge portions of the harness insertion opening 16c of the guide lane 16b formed by the pair of guide plates 16f, 16f, projections 16e, 16e for preventing inward projection are integrally formed. Due to the respective projections 16e for retaining, the inner width W1 of the harness insertion opening 16c is narrower than the inner width W2 of the guide lane 16b. Each of the above-mentioned protrusions 16e for retaining
In the case of the soft flat harness 5B, the length L1 is longer than the length L1 (for example, about 1/4 of the inner width 2 of the guide lane 16b).

According to the structure of the fourth embodiment, the same operation and effect as those of the second embodiment can be obtained, and the guide lane 16b formed by the pair of guide plates 16f and 16f has a thickness of the instrument panel 16. It is thin and can be used in a place where the concave groove-shaped guide lane 16b as in the second embodiment cannot be formed.

FIG. 5 shows a mounting structure of the fifth embodiment. Second
A guide lane 16b similar to that of the embodiment is integrally formed, and a pair of left and right caulking pin portions 16g and 16g are integrally formed on the upper surfaces of the respective projections 16e and 16e for preventing slippage at appropriate intervals T2. Inserting caulking holes at both ends of the belt 17 made of synthetic resin or metal into the pair of left and right caulking pin portions 16g, 16g, and expanding the tops of the respective caulking pin portions 16g, 16g by heat welding or the like. Thus, the belt 17 is fixed to the upper surface of each of the protrusions 16e, 16e for retaining.

The caulking pin portion 16g may be fixed by pressing or screwing a separate pin or screw into the hole on the upper surface of the retaining projection 16e. The belt 17 is integrally formed on the upper surface of one of the protrusions 16e for preventing slippage through a thin hinge portion, and the locking portion for locking the other end of the belt 17 on the upper surface of the protrusion 16e for preventing slippage. May be provided.

The flat harness 5 according to the fifth embodiment has the same functions and effects as the second embodiment, and the belt 17 traverses (closes) the harness insertion opening 16c.
Prevents B from coming off more reliably.

FIG. 6 shows a mounting structure of the sixth embodiment. Second
It is preferable that the same guide lane 16b as that of the embodiment is integrally molded, and the guide lane 16b has both end sides of a square shape as in the fourth embodiment of FIG. In addition, a rectangular spring-like clip 18 is inserted on the lower surface side of each of the protrusions 16e, 16e for preventing slipping out. With the configuration of the sixth embodiment, the clip 18 crosses (closes) the harness insertion port 16c, so that the flat harness 5B can be pressed by the spring force from above, and the flat harness 5B can be more securely prevented from coming off. Become.

In the fifth embodiment of FIG. 5 and the sixth embodiment of FIG. 6, the length L1 of each of the retaining projections 16e, 16e is about the same as the length L2 of the retaining claw 16d of the first embodiment. In addition, if the guide lane 16b is formed in a deep groove shape, the round shaft-shaped harness 5A can be fitted and attached.

[0035]

As is apparent from the above description, in the vehicle harness mounting structure of the present invention, the wire harness is inserted and routed in the guide lane integrally provided on the harness mounting surface of the vehicle body panel. Since the wire harness is held by the projections for preventing the wire harness from coming off the guide lane, the wire harness can be easily attached to the vehicle body without using a separate member.

When a concave groove is provided on the mounting surface of the vehicle body panel to form a guide lane, the wire harness is housed in the guide lane to arrange the wire harness on the surface of the vehicle body panel. The space for use is not needed, and the space can be saved. In other words, it is possible to install the wire harness in an area where the wire harness could not be installed because there is no space for installing the wire on the surface of the vehicle body panel. Further, if the wire harness to be installed is a flat harness having a thin wall thickness, even if the guide lane is projectingly provided on the surface of the vehicle body panel as in claim 3, there is an advantage that the installation space is not so much.

Further, when the length of the protrusion of the harness insertion port is shortened as described in claim 4, the round shaft-shaped wire harness bundled by winding the tape can be smoothly inserted into the guide lane. In addition, as described in claim 6, when the harness insertion opening is closed with the band or the clip, even if the length of the protrusion is short, the stopper is reliably prevented. Moreover, by attaching the band or the clip to the harness insertion opening, it is possible to prevent the wire harness from jumping out from the guide lane. In particular, when the flexible retaining claw is provided as described in claim 5, even the harness having the round shaft shape can be more smoothly inserted into the guide lane.

Further, even if the protrusion of the harness insertion opening is lengthened as in claim 3, when the wire harness is a flat harness, the wire harness can be inserted smoothly and the pullout can be securely prevented. Become.

Further, when the wire harness is arranged in advance on the interior member such as the instrument panel as in claim 7, it is sufficient to fix these interior members to the vehicle body in the automobile assembly line. In the car assembly line,
It is sufficient to connect the wire harnesses. That is, in the automobile assembly line, the work of fixing the wire harness to the vehicle body is not required, and the number of working steps can be significantly reduced.
