JPH118013A - Structure of electrical connection box for vehicle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the number of components of an electrical connection box for a vehicle and to facilitate assembling and maintenance work by integrally forming the electrical connection box to which a connector is fixed on the inner surface of a trim cover, joining the connector to a waiting connector by the closing operation of the trim cover, and at the same time by housing the electrical connection box in the space formed between a trim and a body panel. SOLUTION: When a trim cover 7b is closed, an electrical connection box 9 is housed in a space between a cowl side panel 6 and a trim 7, and at the same time, a connector 13 is joined to a waiting connector 13. Since a lower case 9a of the electrical connection box 9 is integrally formed on the inner surface of the trim cover 7b, the lower case 9a is made unnecessary, and the number of components is reduced. Since a connector 10 is automatically joined to the waiting connector 13 by the closing operation of the trim cover 7b, assembling capability is made easy. When the trim cover 7b is opened, the electrical connection box 9 is drawn out to the outside of a trim, and maintenance such as replacement of a fuse 12 is made easy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an electric junction box for a vehicle, which can reduce the number of parts and can improve assembling and maintenance.

[0002]

2. Description of the Related Art An electrical junction box used for branch connection of a wire harness for automobiles to various electric components is designed such that branch connection points are concentrated in one place and wiring is rationally and economically connected. With the increase in the density of wire harnesses, various types have been developed according to vehicle types or applications.

The electric connection box is installed on a cowl side panel, for example, on the side of a driver's seat, and after connecting each wire harness, is covered with a trim (interior material) together with the cowl side panel.

[0004]

However, the electric junction box has a large number of parts, the man-hours for assembling a wire harness and the like are complicated, and the maintenance of the electric junction box covered with trim is difficult. was there.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electric junction box for a vehicle which can reduce the number of parts and can improve the assembling and maintenance. It is.

[0006]

In order to solve the above-mentioned problems, the present invention provides a trim for covering an interior surface of a vehicle body panel on a vehicle interior side with a trim cover capable of opening and closing a space between the vehicle body panel and the vehicle. While the standby connector is attached to the vehicle body panel facing the trim cover, an electric connection box having an electronic component or a connector coupled to the standby connector is integrally provided on the inner surface of the trim lid. An object of the present invention is to provide a structure of an electric junction box for a vehicle, wherein a connector of the electric junction box is coupled to a standby connector of a vehicle body panel by a closing operation, and the electric junction box is housed in the space.

According to the present invention, the electric connection box is integrally provided on the inner surface of the trim cover provided on the trim, and the operation of closing the trim cover moves the electric connection box into the space between the trim and the vehicle body panel. When housed, the connector of the electric connection box is connected to the standby connector attached to the vehicle body panel.

[0008] The vehicle body panel may be a cowl side panel.

[0009]

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

As shown in FIG. 1, a steering wheel 1 and an instrument panel 2 are arranged at a front portion of a driver's seat of an automobile, and an accelerator pedal 3 and a brake pedal 4 are arranged at a foot portion. .

A front pillar 5 is provided at a front side portion of the driver's seat, and a cowl side panel 6 is joined to a lower portion of the front pillar 5. A trim (interior material) 7 that covers the inner surface on the vehicle cabin side with the space S therebetween is attached.

As shown in detail in FIGS. 2 and 3, the lower end 6a of the cowl side panel 6 is joined to the upper surface of the floor panel 8, and the lower portion 7A of the trim 7 is connected to the upper surface of the floor panel 8. The cowl side panel 6 is covered to the vicinity.

The lower trim 7A is formed separately from the upper trim 7B so that the upper trim 7B can be retrofitted to the cowl side panel 6 after being assembled to the vehicle body.

The lower trim 7A is provided with a trim cover 7b connected by a hinge portion 7a so as to be openable and closable. As shown in FIG. The space S between the cowl side panel 6 and the cowl side panel 6 can be closed when the trim lid 7b is closed outside the vehicle compartment as shown in FIG. 3B.

An electric connection box 9 is provided on the inner surface of the trim lid 7b.
The lower case 9A is integrally formed, and in the lower case 9A, a wiring component such as a bus bar is accommodated as in the conventional case. Also, this lower case 9A
The connector 10, the relay 11, and the fuse 12 are provided on the outer surface of the upper
And other electronic components.

An electric junction box 9 integral with the trim lid 7b
Are housed in the space S when the trim cover 7b is closed.

A standby connector 13 to which the connector 10 of the electric connection box 9 is connected when the trim cover 7b is closed is attached to the cowl side panel 6 facing the trim cover 7b.

With the above configuration, the lower trim 7
In the lower case 9A on the inner surface of the trim cover 7b of A, wiring components such as bus bars are accommodated, and after electronic components such as relays 11 and fuses 12 are attached to the upper case 9B, the lower trim 7A is moved to a position below the upper trim B. Is attached to the cowl side panel 6.

When the trim cover 7b is closed as shown in FIGS. 3A and 3B sequentially from the state shown in FIG. 2, the electric connection box 9 moves the cowl side panel 6 and the trim 7
At the same time, the connector 10 of the electric connection box 9 is connected to the standby connector 3 of the cowl side panel 6.

As described above, since the lower case 9A (or the upper case 9B) of the electric connection box 9 can be integrally formed on the inner surface of the trim cover 7b, the lower case 9A becomes unnecessary and the number of parts is reduced.

Further, the connector 10 of the electric connection box 9 can be automatically connected to the standby connector 13 of the cowl side panel 6 by closing the trim cover 7b, thereby improving the assembling property. Further, when the trim lid 7b is opened as shown in FIG. 2, the electric connection box 9 is pulled out of the trim 7, so that maintenance such as replacement of the relay 11, the fuse 12, and the like is improved.

[0022]

As is apparent from the above description, the structure of the electric connection box for a vehicle according to the present invention is realized by integrally providing the electric connection box on the inner surface of the trim cover of the trim and closing the trim cover. When the electric connection box is housed in the space between the trim and the body panel, the connector of the electric connection box is connected to the standby connector attached to the body panel, so the lower case of the electric connection box is integrated with the trim lid. Since molding is possible, the number of parts can be reduced.

Also, the connector can be automatically connected to the standby connector by closing the trim cover, so that the assemblability is improved, and when the trim cover is opened, the electric connection box is pulled out of the trim. The nature also improves.
