[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a vehicle such as a fixed glass or a wiring harness of an electric component mounted on the periphery thereof.

[0002]

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

As a wiring structure of a wire harness in a back door, for example, a wiring structure as shown in FIG. 8 is known. That is, the wire harnesses 82 and 84 configured corresponding to the arrangement of each electrical component are connected to the rear glass 8.
The wiring harnesses 82 and 84 are provided with terminals or connectors (85 to 90) which are disposed in hollow portions formed inside the back door on both left and right sides of the back door 0 from the openings formed in the door panel. It is designed to be connected to electrical components. On the other hand, each wire harness 8
The terminals on the other end side of the components 2 and 84 are connected to a main harness 81 connected to a control box or the like below the rear glass 80.

[0004]

However, in the above-described wiring structure, it is necessary to insert each wire harness into a hollow portion in the back door, so that the assembling property is extremely poor, and moreover, each electrical component has Since the wiring harnesses are individually routed, the number of wirings, the number of connectors, the number of fittings, and the like are large.

In recent years, some of the above-mentioned electrical components have been selectively installed as an option in order to differentiate the type of vehicle. It is necessary to make the structure of the harness different for each specification (country) in accordance with the working voltage and the standard. For this reason, depending on the type of vehicle, there are more than several tens of types of wire harness that are routed around the rear glass as described above, and this places an excessive burden on workers in assembling vehicles and managing parts. I have.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to simplify and commonize a wiring structure around a glass of a vehicle and to improve the assemblability of the vehicle. It is intended to provide.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a wiring structure for a fixed glass of a vehicle and an electric component disposed around the fixed glass, wherein the wiring is formed on a weather strip for holding the fixed glass on a vehicle panel. The corresponding conductor pattern is integrally formed, and the weather strip is provided with a branch portion that allows a part of the conductor pattern to branch.

According to this wiring structure, the electrical component can be wired by attaching the weather strip to the vehicle panel and electrically connecting the conductor pattern and the electrical component via the branch portion. This eliminates the need for wiring work for wiring electrical components while inserting a wire harness into the hollow portion of the back door as in the related art. Also, when a plurality of electrical components are connected to the conductor pattern via the branch portion, the conductor pattern becomes a common wiring portion for each electrical component, and therefore, the number of connectors for connection with the main harness side, and the number of terminal fittings The number can be reduced.

In particular, in the case where wiring selected from a plurality of types of wirings according to the specifications of the vehicle is made, a conductor pattern including wirings of all specifications may be formed. Thus, a common weatherstrip can be used regardless of specifications. This eliminates the need for a conventional wiring structure for each specification, and reduces the burden of assembling the vehicle and managing parts.

Further, if the conductor pattern is formed from independent patterns parallel to each other (claim 3), the structure of the conductor pattern is simple, so that the productivity of the weather strip is good, and when the branch portion is set. It is possible to increase the degree of freedom.

[0011] Further, a branch portion is formed from an opening concave portion for exposing the conductor pattern to the outside, and a connector of an electrical component is removably mounted in the concave portion. If the conductor pattern is formed so as to achieve the electrical connection (claim 4), the connector on the electrical component side can be directly connected to the conductor pattern. In particular, if the conductor pattern is formed of a conductive strip and a terminal of the connector is provided with a holding portion of the conductive strip formed of a pair of spring pieces (claim 5), the structure of claim 4 is realized. This can be implemented with a simple configuration.

Further, if one end of the electric wire is connected to the conductor pattern at the branch portion, and a connector to be connected to the electric component is attached to the other end of the electric wire, the conductor pattern and the electric component are fitted into the connector. It becomes possible to connect by (claim 6). In this case, in particular, the branch portion is formed from an opening recess for exposing the conductor pattern to the outside, and the connector is fitted and held in the opening recess so as to be connectable to a mating connector. The connector can be provided integrally with the weather strip.

FIGS. 3 and 4 (a) schematically show the structure of the connecting portion 26A and the connector 34A of the electric opening / closing curtain.

As shown in these figures, the connecting portion 26A is formed with a concave portion 27 which opens toward the passenger compartment (to the right in FIG. 4A), whereby each bus bar 18a,
The configuration is such that a part of 18 d and 18 e is exposed in the recess 27.

On the other hand, the connector 34A has three upper and lower stages of terminal housings 40 in a housing made of resin or the like. , 25b crimped terminal 4
4 is stored and held. A slit-shaped opening 42 for introducing each bus bar 18a, 18d, 18e is formed in front of the housing (left side in the figure) corresponding to each terminal storage section 40. Although not shown in detail, the terminal 44 has a female terminal structure having a pair of upper and lower leaf spring-shaped holding pieces for holding the bus bar.

The connection is made as shown in FIG.

d is introduced into the terminal housing 40 through the opening 42, and FIG.
When the connector 34 is completely fitted into the recess 27 as shown in FIG. 2B, the bus bars 18c and 18d are interposed between the pressing pieces of the terminals 44, whereby the terminals 44 of the connector 34a and the conductor patterns 18 are interposed. Connection is achieved. Note that the first bus bar 18a is not connected because the corresponding terminal storage section 40 of the connector 34A is empty.

The above is the description of the connector 3 of the electric opening / closing curtain.
4A and the structure of the connecting portion 26A for connecting this,
The structures of the other connectors and the corresponding connection portions are basically the same as those in the above-described example. However, as for the connector 36 of the main harness 38, it is necessary to store the terminals 44 of the five electric wires 38a to 38e as described above. A total of six terminal storage sections 40 in a row are defined and formed.
4 are stored.

According to the back door 10 configured as described above, most of the wiring of each electrical component around the rear glass 14 is provided integrally with the weather strip 16 as the conductor pattern 18 as described above. Wiring of each electrical component can be performed only by attaching the weather strip 16 to the door panel 12 integrally with the door panel 14 and connecting each electrical component and each connector of the main harness 38 to the weather strip 16. This eliminates the need for the wiring work of wiring electrical components while inserting a wire harness into the hollow portion formed in the back door as in the conventional case.As a result, the workability of wiring the electrical components such as the defogger is reduced. Can be greatly improved.

Further, the same weatherstrip 16 can be used even when a motor-operated curtain or a high-mount stop lamp is selectively mounted depending on the specifications of the vehicle or mounting of options. For this reason, not only the above-mentioned electric opening / closing curtain and the like but also a large number of conductor patterns 18 including the rear glass 14 and a portion corresponding to the wiring of all the electrical components attached around the rear glass 14 are configured. The same weatherstrip 16 can be used even when the electrical components are selectively attached. Therefore, it is not necessary to prepare wire harnesses for each specification and use them properly as in the related art, and it is possible to greatly reduce the burden on the operator in assembling the vehicle and managing parts.

By the way, depending on the specifications of the vehicle, for example, when the electric open / close curtain is not attached, the connecting portion 26
A masking member may be attached to A and 26B so as to cover the recess 27. As shown in FIG. 5, the first, third, and fifth bus bars 18a, 18
A masking member 50 having substantially the same shape as that of the connector 34A having the slit-shaped cutouts 52 corresponding to 8d and 18e may be formed, and this may be fitted and mounted in the concave portion 27. By doing so, the masking member 5
0, each bus bar 18a, 18d, 18e is interposed in each cut 52, so that each bus bar 18
Deformation of a, 18d, 18e and contact between bus bars can be effectively prevented. If the masking member 50 is made of the same material as the weatherstrip 16, a feeling of strangeness can be reduced and the masking effect can be enhanced. Although FIG. 5 shows an example of the masking member 50 for the connection portions 26A and 26B, a similar masking member can be configured for other connection portions.

Further, according to the back door 10, the wiring structure around the rear glass 14 is effectively simplified as compared with the conventional wiring structure in which the wiring harness of the electrical component is routed around the rear glass 14. There is also the advantage that it can be done.

That is, in the conventional wiring structure, a wire harness is provided for each electrical component such as a defogger and a high-mount stop lamp. For example, a ground wire is provided for each wire harness. for that reason,
As the number of electrical components increases, a number of ground wires are routed around the rear glass, causing the wiring to become bulky. However, according to the wiring structure of the above-described embodiment, the ground wire 38a of the main harness 38 is connected to the first bus bar 18a of the conductor pattern 18 as described above.
The ground wire from each electrical component is connected to the bus bar 18a, that is, since the first bus bar 18a is commonly used as the ground wire, the ground wire is bulky as in the related art even when many electrical components are attached. Such a situation does not occur. For this reason, the number of electric wires can be reduced by using the conductor pattern 18 as a common wiring portion without being limited to the ground wire, and thereby the wiring structure around the rear glass 14 can be effectively simplified.

In the conventional wiring structure, the electrical components such as the defogger and the wire harness or the wiring harness and the main harness are connected by fitting the connectors. In the above-described wiring structure, each electrical component and the like are connected. By directly connecting the connector to the weather strip 16, the connection between the electrical component such as the defogger and the conductor pattern 18 or the connection between the main harness 38 and the conductor pattern 18 is performed. The number of connectors can be reduced, and the conductor pattern 18 serves as a common wiring portion for each electrical component. By connecting the main harness 38 to the conductor pattern 18, a connector for connection with the main harness side is provided. The number and the number of terminal fittings are reduced. for that reason,
This also achieves simplification of the wiring structure.

The above embodiment is an example of a back door to which the wiring structure of the vehicle according to the present invention is applied, and not only the specific structure of the back door 10 but also the specific structure of the weather strip 16 are described in the present application. Changes can be made as appropriate without departing from the spirit of the invention.

For example, in the back door 10, FIG.
As shown in (a) and (b), when the connector 34A is inserted into the connection portion 26A provided on the weather strip 16, the control wire 2 from the electric opening / closing curtain is inserted.
5a and 25b are connected to the fourth bus bar 18d and the fifth bus bar 18e of the electric conductor pattern 18, respectively. As shown in FIG. 6, the fourth bus bar 18d and the fifth bus bar 18e respectively have electric wires. 58,6
0 is connected to the connector 56 by soldering, and the other side of the electric wires 58, 60 is attached to the connector 56, and the connector 56 is connected to the connector 34A to connect the control wires 25a, 25b to the fourth and fifth control wires. You may make it connect to each bus bar 18d, 18e. Such a structure is effective, for example, when the dimensions such as the thickness of the weather strip 16 are not enough to fit the connector of the electrical component. However, when the fitting space cannot be secured in the weather strip, other than such a method, the connector may be directly fitted to the electrical component side, or the connector may be fitted at a place where space can be secured. Good. In the case where the connector 56 is connected to the bus bars 18d and 18e via the electric wires 58 and 60 as described above, the connector 56 is connected as shown in FIGS.
Into the recess 27 in a state where it can be connected to the mating connector,
You may make it hold | maintain.

In the weather strip 16 of the back door 10, the conductor pattern 18 is formed by the first bus bar 18a and the second to fifth bus bars 18b to 18e parallel to the first bus bar 18a. Conductor pattern 1
8 need not be parallel patterns to each other,
What is necessary is just to make it comprise suitably according to the starting conditions, such as the positional relationship of the electrical components to be attached. However, according to the parallel pattern as described above, there is an advantage that the structure of the conductor pattern 18 is simple, so that the productivity is good and that the degree of freedom in setting the connection portion of the connector is increased. In addition, the conductor pattern 18 does not necessarily need to be formed of a bus bar as described above, and may be formed of, for example, a general electric wire (bare wire) or an FPC.

[0039]

As described above, according to the present invention, the conductor pattern corresponding to the wiring of the electrical component is integrally formed on the weather strip for holding the fixed glass to the vehicle panel, and the conductor pattern of the conductor pattern is formed on the weather strip. Wiring of each electrical component is performed by simply attaching the weather strip to the vehicle panel and electrically connecting the conductor pattern and the electrical component via the branch portion because the branch part that can partially branch is provided. Can be. This eliminates the need for the wiring work of wiring the electrical components while inserting the wire harness into the hollow portion formed in the back door as in the related art, thereby improving the assemblability of the vehicle. When a plurality of electrical components are connected to the conductor pattern via the branch portion, since the conductor pattern is a common wiring portion for each electrical component, the number of connectors for connection to the main harness side and the number of terminal fittings are reduced. The number of joints can be reduced,
As a result, the wiring structure can be simplified.

In particular, when a wiring selected from a plurality of types of wirings according to the specifications of the vehicle is made, if a conductor pattern including wirings of all specifications is formed, regardless of the specification, A common weatherstrip can be used, and a conventional wiring structure for each specification is not required. As a result, the burden of assembling the vehicle and managing the parts is greatly reduced.

Further, if the conductor pattern is formed from independent patterns parallel to each other, the structure of the conductor pattern is simple, so that the productivity of the weather strip is good, and the degree of freedom in setting the branch portion is improved. It is possible to increase.

Further, a branch portion is formed from an opening concave portion for exposing the conductor pattern to the outside, and a connector of an electrical component is detachably mounted in this concave portion. If the conductor pattern is formed so as to achieve the electrical connection described above, the connector on the electrical component side can be directly connected to the conductor pattern. Therefore, the number of connectors and the like used for wiring can be reduced, thereby achieving simplification of the wiring structure.

Further, if one end of the electric wire is connected to the conductor pattern at the branch portion, and the other end of the electric wire is fitted with a connector to be connected to the electric component, the conductor pattern and the electric component are fitted into the connector. Can be connected. In this case, in particular, if the branch portion is formed from an opening recess that exposes the conductor pattern to the outside, and the connector is fitted and held in the opening recess so as to be connectable with a mating connector, the connector can be a weather strip. Can be provided integrally.
