DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric junction box disposed on an inner wall of a vehicle body of an automobile, for example.

[0002]

2. Description of the Related Art Conventionally, various types of electric connection boxes, which store various electric components for automobiles and serve as connection junctions of wiring such as wire harnesses, are available in various types according to vehicle types and applications. is there. FIG. 3 shows an electric connection box 31 of a type directly fixed to the inner wall of a vehicle body by means such as bolting.
[Also referred to as a junction box (J / B)].

The electric connection box 31 includes a lower case 32 made of a synthetic resin and an upper case (not shown) made of a synthetic resin fitted to the upper part of the lower case 32. The lower case 32 houses an electrical component storage block 34 having an electrical component mounting portion 33 for mounting electrical components. A mounting portion 35 is formed to project from the side wall of the lower case 32, and the mounting portion 35 is provided with a pair of mounting holes 36. A hole 37 is formed between the lower case 32 and the mounting portion 35, and the mounting portion 35 is provided with a reinforcing rib 38 for preventing distortion and bending. Further, a connector 39 for connecting wiring such as a wire harness is protruded from a side wall of the lower case 32, and a plurality of fixing portions 40 are provided.
Are formed to protrude. Further, through holes 41 are formed in the fixing portions 40, respectively.

When the electric connection box 31 is fixed to the inner wall of the vehicle body, the electric connection box 31 is first held at a predetermined position on the inner wall of the vehicle body. I was screwed.

[0005]

However, since the mounting portion 35 is used only for mounting the electric connection box 31 on the inner wall of the vehicle body, there is a problem that the space of the mounting portion 35 is not effectively used. Further, since the connector 39 is protruded from the side wall of the lower case 32, the outer shape of the electric connection box 31 becomes large, and a large exclusive space is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric junction box which can effectively utilize the space of a mounting portion and can be made compact. It is in.

[0007]

Means for Solving the Problems In order to achieve the above object, according to the first aspect of the present invention, there is provided a lower case for accommodating electric components and an upper case for covering an upper opening of the lower case, An electrical connection box provided with a mounting portion on a side wall of the lower case, and having a mounting hole in the mounting portion, wherein a fitting hole for fitting a connector to the mounting portion is formed. I have.

According to a second aspect of the present invention, in the electric connection box according to the first aspect, a pair of the mounting holes is provided, and the fitting hole is disposed between the two mounting holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of an electric junction box according to the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the electric connection box 11 includes an upper case 12 and a lower case 13 made of synthetic resin. The upper case 12 has a box shape with an open lower surface. The lower case 13 has a box shape with an open top, and the upper case 12 is formed so that the upper case 12 can be fitted thereon. An electrical component housing block 14 is housed in the lower case 13. A plurality of electrical component mounting portions 15 are protrudingly provided on the upper surface of the electrical component housing block 14 so that electrical components (not shown) can be mounted on the electrical component mounting portions 15. Further, an electric circuit or the like constituted by a bus bar or the like is housed in the electric component housing block 14.

A plurality of fixing portions 16 project from the lower portion of the side wall of the lower case 13, and through holes 17 are formed in the fixing portions 16, respectively. A mounting portion 18 is formed to project from the entire lower surface of one side wall of the lower case 13, and the mounting portion 18 has one fitting hole 19 and a pair of mounting holes 20. It is arranged between the holes 20.

Then, a bolt (not shown) is inserted through the through hole 17 of the fixing portion 16 and the mounting hole 20 of the mounting portion 18 and screwed to the inner wall of the vehicle body so that the electric connection box 11 is fixed to the inner wall of the vehicle body. Has become. Also, the fitting hole 19
The connector 21 can be fitted into the connector. Therefore, the connector 21 for connecting wiring such as a wire harness is not provided on the side wall of the lower case 13.

The operation and effect of the present embodiment will be described below. In the present embodiment, a fitting hole 19 for fitting the connector 21 to the mounting portion 18 is formed. For this reason, the mounting portion 18 is used not only for mounting on the inner wall of the vehicle body but also for mounting the connector 21, so that the space of the mounting portion 18 can be effectively used. it can. Also, by fitting the connector 21 protruding from the side wall of the lower case 13 into the fitting hole 19, the electrical connection box 1 is provided by the space where the connector 21 protrudes.
1 Since the outer shape can be reduced, the electric connection box 11
Can be made more compact. Further, a fitting hole 19 is formed between the pair of mounting holes 20 in the mounting portion 18. Thereby, the fitting hole 19 can be arranged by effectively utilizing the space between the pair of mounting holes 20, and the size of the mounting portion 18 can be reduced. In the present embodiment, since the mounting portion 18 projects outside the lower case 13, the connector 21 can be easily attached to and detached from the fitting hole 19.

The above embodiment can be modified and embodied as follows. In the above embodiment, one connector 21 is fitted into the fitting hole 19, but two or more connectors 21 may be fitted into the fitting hole 19. In the lower case 13, the two fixing portions 16 formed on the opposite side of the mounting portion 18 are integrated, and a fitting hole 19 for fitting the connector 21 is formed therein. In the above-described embodiment, the fitting hole 19 is formed in a rectangular parallelepiped. However, the shape of the fitting hole 19 may be any shape as long as the connector 21 can be fitted, and is particularly limited. is not.

[0014] The "electric junction box" referred to in this specification is:
It means any form of intervening existence provided to house various electric components and connect them to wire harnesses and other wiring, and is limited to so-called junction blocks (J / B) is not.

[0015]

Since the present invention is configured as described above, it has the following effects. According to the first aspect of the present invention, the fitting portion has the fitting hole for fitting the connector. Thus, the mounting portion is used not only for mounting on, for example, the inner wall of the vehicle body but also for fitting the connector, so that the space of the mounting portion can be effectively used.

In addition, by fitting the connector protruding from the side wall of the lower case into the fitting hole, the outer shape of the electric connection box can be reduced by the space where the connector protrudes. In addition, the size of the electric connection box can be reduced.

According to the invention described in claim 2, according to claim 1
In addition to the effects of the invention described in (1), the fitting hole can be arranged by effectively utilizing the space between the pair of mounting holes, so that the size of the mounting portion can be reduced.
