Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a wire harness connected to an electric component such as a high mount stop lamp mounted around a fixed glass such as a back door of a vehicle.

[0002]

2. Description of the Related Art In recent years, a number of electrical components such as a rear glass defogger, a high mount stop lamp, and an electric opening / closing curtain have been mounted on a back door of a vehicle. A wire harness for each of these electrical components is wired in the.

As a wiring structure of the wire harness in the back door, for example, a wiring structure as shown in FIG. 6 is known. That is, the wire harnesses 52, 54 configured corresponding to the arrangement of the electrical components are arranged in the hollow portions formed inside the back door on both the left and right sides of the rear glass 52, and Terminal,
Alternatively, the connector or the like (55 to 60) is led out from the opening formed in the door panel and connected to the electrical component. On the other hand, the terminals on the other end side of the wire harnesses 52, 54 are connected to the main harness 51 connected to a control box or the like below the rear glass 50.

[0004]

However, in the above wiring structure, since it is necessary to insert each wire harness into the hollow portion in the back door, the assembling property is extremely poor, and the wire harness is inserted upside down. It is easy to cause erroneous work. In particular, when a plurality of different wire harnesses are routed around the rear glass as described above, there are problems that erroneous work is more likely to occur and component management becomes complicated.

Further, at the time of installation work, the connector or the like drawn out from the opening of the door panel is suddenly pulled back into the hollow portion during the work, or the connector is buried in the bundle of wire harnesses. It is difficult to hold the cable fixedly, and therefore, it may be necessary to connect to the electrical component while searching for a connection terminal or the like in the wiring work. Therefore, there is a problem that the workability of connecting the wire harness to the electrical component or the main harness is poor.

The present invention has been made to solve the above problems, and provides a wiring structure of a wire harness which can effectively improve the assembling property of the wire harness connected to an electric component such as a stop lamp. It is intended to be provided.

SUMMARY OF THE INVENTION The present invention provides a wiring structure of a wire harness which is arranged around a fixed glass of a vehicle and is connected to electrical components, and a weather strip for holding the fixed glass on a vehicle panel. The wire harness is integrally provided, and the connection member of the wire harness is provided so as to be exposed from the weather strip to the outside.

According to this structure, the wire harness can be assembled to the vehicle integrally with the work of mounting the weather strip on the vehicle panel. Therefore, it is not necessary to insert the wire harness into the vehicle panel as in the conventional case, and the assembling property of the wire harness is improved. Moreover, since the parts management may be performed integrally with the weather strip, it is not necessary to manage the parts for the wire harness alone.

In such a structure, the wire harness is embedded in the weatherstrip by integral molding, or a recess is formed in the weatherstrip so that the opening can be closed when the weatherstrip is attached to the vehicle. By disposing the wire harness, the wire harness can be integrally provided on the weather strip without exposing the wire harness to the outside. In particular, when the wire harness is arranged in the recess that can close the opening, the wire harness can be attached to and detached from the weather strip, and thus it is possible to easily cope with disconnection of the wire harness.
In this case, as the recess for arranging the wire harness,
By using the mounting groove into which a part of the vehicle panel is fitted at the time of mounting on the vehicle, it is possible to effectively utilize the conventional shape of the weather strip to integrally provide the wire harness to the weather strip.

Further, by arranging one or a plurality of electric wires constituting the wire harness in the weather strip in a separated state, it is possible to reduce swelling of the weather strip due to the wire harness. Further, when the electric wires are separated into individual wires, bare wires can be used as the electric wires, and the manufacturing cost of the wire harness can be reduced.

Further, if the connecting member is fixed to the weather strip, it is possible to dispose the connecting member at a specific portion of the vehicle only by mounting the weather strip on the vehicle. Workability of connecting parts and main harness is improved.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows a part of a back door of a vehicle to which a first embodiment of a wiring structure for a wire harness according to the present invention is applied. Back door 10A shown in FIG.
Is a back door of a wagon type vehicle, and is openably and closably supported by a vehicle body by being connected to a vehicle body frame via a hinge at a rear portion of the vehicle.

As shown in the figure, a rear glass 12 is attached to the center of the back door 10A. The rear glass 12 is made of a single piece of glass and is fixed, that is, in a state in which it cannot be opened and closed, by being fitted into the opening formed in the door panel 11 of the back door 10A via the weather strip 14. ing.

More specifically, the weather strip 1
Reference numeral 4 denotes an annular shape corresponding to the shape of the rear glass 12, and as shown in FIG. 2, the inner and outer surfaces (upper and lower surfaces in the figure) of the rear glass 12 are fitted around the glass holding groove 16 and the vehicle along the entire circumference thereof. Each groove 18 is formed. Then, while the weather strip 14 is mounted on the rear glass 12 so that the outer edge portion of the rear glass 12 is fitted into the glass holding groove 16, the door panel 1 of the back door 10A is mounted on the mounting groove 18.
By mounting the weather strip 14 on the door panel 11 so that the first flange 11 a is fitted, the rear glass 12 is mounted on the door panel 11 of the back door 10 </ b> A via the weather strip 14.

Although not shown, electrical components such as a defogger, a high mount stop lamp, and an electric opening / closing curtain are attached to the rear glass 12 and its surroundings, and a wire harness for each of these electrical components. 20 is arranged around the rear glass 12.

Here, as a feature of the present application, the wire harness 20 is integrally provided on the weather strip 14, and more specifically, by being integrally molded with the weather strip 14, as shown in FIG. It is embedded in the weather strip 14.

One end of an electric wire forming the wire harness 20 is led out to the outside at a position corresponding to each electric component through a notch portion formed in the weather strip 14, and each electric component is connected to this derived portion. It is possible to connect to each electric component by mounting a connecting member such as a connecting terminal or a connector to the electric component. Specifically, as shown in FIG. 1, one end of each electric wire is led out to the outside of the weather strip 14 at the upper portion and the left and right side portions of the rear glass 12. Then, the connector 22 connected to the high mount stop lamp is connected to the electric wire led to the upper portion of the rear glass 12, and the pair of terminals 24a and 24 are connected to the defogger to the electric wires led to the left and right sides of the rear glass 12.
b is a pair of upper and lower connectors 26 connected to the electric opening / closing curtain to the electric wire led to the left side portion of the rear glass 12.
a and 26b are mounted respectively.

On the other hand, the other ends of the respective wires in the wire harness 20 are both led out to the outside from the weather strip 14 at the lower central portion of the rear glass 12 and attached to a common connector 28. And this connector 28
By being connected to the connector 32 of the main harness 30, the wire harness 20 is connected to the main harness 3
It is designed to be connected to a control box or the like via 0.

Back door 10A constructed as described above
According to the above, the wire harness 20 of the electrical component arranged around the rear glass 12 has the weather strip 1 as described above.
4, the wire harness 20 is attached to the back door 1 integrally with the work of attaching the weather strip 14 to the door panel 11 when the rear glass 12 is attached.
It can be installed at 0A. Therefore, it is unnecessary to carry out the wiring work by inserting the wire harness into the hollow portion formed in the back door as in the related art, and the wiring work by the wire harness alone becomes unnecessary.
It is possible to greatly improve the assembling property of.

Moreover, the weather strip 14 is attached to the door panel 11 by fitting the flange 11a to the flange fitting portion 18a based on the shape characteristics of the opening of the door panel 11.
Since it is done while inserting, it is difficult for erroneous work to occur. Therefore, unlike the conventional structure in which the wire harness is individually inserted into the hollow portion of the back door, there is almost no error in the wiring direction of the wire harness. Therefore, also in this respect, the assembling property of the wire harness 20 can be improved.

When the wire harness is inserted into the hollow portion of the back door as in the prior art, the wire harness is routed to the back door because of the structural limitation of the hollow portion of the back door or the reason for ensuring the insertion workability. It may be required to divide the wire harness into a plurality of wire harnesses (see FIG. 6), but in the above structure in which the wire harness does not need to be inserted into the back door, the wire harness 20 is divided as described above. It is possible to provide it integrally without performing. Therefore, it is possible to simplify the structure of the wire harness 20 itself and effectively reduce the manufacturing cost, and it is also advantageous in terms of parts management.

Further, in the conventional wiring structure, the connection terminal or the like led out from the opening of the door panel is suddenly pulled back into the hollow portion of the back door during the wiring work of the wire harness, or the connection terminal is connected to the wire harness. It is difficult to hold the connection terminals and the like fixedly because they are buried in a bundle of wires, so that in the wiring harness wiring work, it may be necessary to search for the connection terminals and connect them to the electrical components. However, according to the above structure, once the weather strip 14 is mounted on the back door 10A, the connector 22 or the like can be held at a substantially specific position, and the connector 22 or the like is buried in the bundle of wire harnesses. There is no such thing. Therefore, it does not take time and effort to find connection terminals and the like, and electrical components and main harness 30
The connection work of the connector 22 and the like can be quickly performed. Therefore, also by this, the assembling property can be improved.

Further, in the conventional wire harness, in order to ensure convergence, the wire harness is wholly or partially inserted into the tube, or the wire harness is fixed by a binding band or the like. But,
As described above, the wire harness 20 is attached to the weather strip 1
If it is integrally molded into the inside of 4, the binding members such as the tube and the binding band are not required, and there is an advantage that the manufacturing cost can be reduced.

In addition, since the wire harness 20 is integrally provided on the weather strip 14, the wire harness 20 and the weather strip 14 which have conventionally been individually managed can be integrally managed. Therefore, there is also an advantage that it is advantageous in terms of component management.

Next, a back door of a vehicle to which the second embodiment of the wiring structure of the wire harness according to the present invention is applied will be described with reference to FIG. The back door 10
Portions common to A will be described using the same reference numerals.

The structure of the back door 10B shown in the figure is also basically the same as that of the back door 10A, but the electric wires constituting the wire harness 20 are divided into one or a plurality of unit wire harnesses 21, and The structure is different from that of the back door 10A in that they are integrally formed with the weather strip 14 in a state of being arranged in the vertical direction.

That is, if the type and number of electrical components attached to the back door 10B increase, the wire harness 20 becomes bulky. Therefore, the back door 10A
In such a structure, the upper end portion of the weather strip 14 may bulge, resulting in poor appearance and impaired appearance quality. However, if the wire harness 20 is divided and arranged in the vertical direction for each unit harness 21 like the back door 10B, it is possible to prevent the weather strip 14 from locally bulging extremely. This makes it possible to maintain the appearance quality. In particular, as shown in the figure, if the wire harness 20 is arranged between the flange 11a of the door panel 11 and the rear glass 12, the presence of the rear glass 12 and the flange 11a causes
It is possible to more reliably suppress the bulging of the weather strip 14 as described above.

Further, according to this structure, when the unit harness 21 is a single wire, for example, each unit harness 21 is arranged in the weather strip 14 as a bare wire, whereby the weather strip 14 also serves as an insulating material. can do. Therefore, in this case, since the insulating material is not necessary, it is possible not only to further alleviate the bulging of the weather strip 14 by the wire harness 20, but also to reduce the manufacturing cost of the wire harness. There is an advantage.

In addition to separating the wire harness 20 into the unit harnesses 21 and arranging them in the vertical direction as described above, the same thing can be done by, for example, bundling the entire wire harnesses 20 and embedding them in the weather strip 14. The effect of can be obtained.

According to this structure, since the wire harness 20 can be attached to and detached from the weather strip 14 as described above, in addition to the characteristic features of the back door 10A, the wire harness 20 can be replaced by a wire break or the like. Is possible.

In addition, as the structure in which the wire harness 20 is detachably attached to the weather strip 14 as described above,
In addition to the structure using the mounting groove 18 as described above, for example, a structure in which a hollow portion is separately formed in the weather strip 14 and the wire harness 20 is inserted into the hollow portion through a notch or the like may be adopted. it can. However, in this case, from the viewpoint of ensuring appearance quality or preventing disconnection, the weather strip 14 is attached to the door panel 11 so that the wire harness 20 can be reliably prevented from being exposed to the outside. Need to be formed.

A plurality of protrusions 19 are provided in the mounting groove 18.
May be provided at a constant interval so that a plurality of harness arranging portions 18b are formed. With such a structure, the bulging of the weather strip 14 can be mitigated similarly to the wiring structure in the back door 10B.

Each of the above-described embodiments is a typical example of a vehicle back door to which the wiring structure of the wire harness according to the present invention is applied, and the back doors 10A, 10B, 1 are shown.
Not only the concrete structure of 0C itself, but also the wire harness 2
The specific wiring structure of 0 can be appropriately changed without departing from the scope of the present invention.

For example, in the back door 10A, one end of each unit harness is led out to the outside through a notch portion or the like formed in the weather strip 14, and a connector or the like is attached to this lead-out portion so that each Although it can be connected to an electrical component, for example, as shown in FIG. 5, the connector 22 or the like may be fixed to a specific portion of the weather strip 14. According to this structure, the door panel 1
