Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electric junction box used for wiring of an electric circuit of an automobile.

[Conventional technology]

As shown in FIG. 4, a conventional electric connection box has a structure in which a plurality of connector portions such as a plurality of fuse cavities 13A and relay cavities 13B are erected on a horizontal connector mounting surface 12 of a box-shaped case 11. . Therefore, fuse 14, relay
Electrical functional parts such as 15 are the connector mounting surface which is the horizontal reference surface
It is inserted and removed from the direction of the arrow perpendicular to 12. Reference numeral 16 denotes a waterproof cover that is worn as needed.

The case 11 of the electric junction box B needs a depth d to accommodate the connector. Further, if the height of the electrical functional component, for example, the fuse 14, is h, the size of the waterproof cover 16 is ignored when the electrical junction box B is mounted on a vehicle body or a panel in consideration of the detaching work for maintenance. Even so, it is necessary to select a site where a space of d + h or more is secured.

[Problems to be solved by the invention]

The installation space of the electric junction box is limited to a narrow space such as an engine room or an instrument panel, and tends to be more and more limited as the number of electric components mounted on the vehicle increases in pursuit of safety and comfort of the vehicle.

In view of such circumstances, an object of the present invention is to provide an electric junction box having a structure in which a large number of electric functional parts can be mounted and a small space can be attached.

[Means for solving the problem]

To achieve the above task, the electrical junction box of the present invention
In an electric connection box having a mounting surface having connectors for various electric functional parts such as a haze and a relay on an upper surface, a plurality of mounting surfaces are inclined in one direction, and an inclined step portion is formed between adjacent mounting surfaces. The step portion of the mounting surface having the connector portion for the tall electric functional component is formed to be larger than the step portion of the mounting surface having the connector portion for the short electric functional component.

The above configuration will be specifically described with reference to the drawings showing the embodiments.

〔Example〕

FIG. 1 is a perspective view of the electric connection box, and FIG.
2 shows a cross-sectional view taken along the line II.

1 and 2, reference numeral 1 denotes a case of an electric connection box A, on the upper surface of which a plurality of mounting surfaces 2 (2a, 2b, 2c, 2d, 2e) are directed in one direction between reinforcing frames 3 on both sides. Inclined portions 2a ', 2b', 2c ', 2
It is configured with d 'interposed. The mounting surface 2 is a two-stage mounting surface 2a, 2b provided with a relatively large stepped portion 2a ', 2b' for a tall electric functional component such as a relay.
And three-stage mounting surfaces 2c, 2d, 2e provided with relatively small steps 2c ', 2d' for short electric functional components such as fuses, and a plurality of mounting surfaces 2a. A relay connector part 4, a circuit breaker connector part 5 on both sides together with a central relay connector part 4 on a mounting surface 2b, and a fuse having a large number of fuse terminal insertion holes 6a on mounting surfaces 2c to 2e. Each of the connector portions 6 is inclined (about 45 ° in the illustrated example) with respect to the reinforcing frame 3 and protrudes in a certain direction. Further, screw holes 7 for attaching the electric connection box A to a panel or the like are provided at both ends of the reinforcing frame 3.

[Action]

As is clear from FIG. 2, the electric junction box A according to the present invention has the connector portions 4 (5) and 6 provided at an angle with respect to the reference surface of the case 1, for example, the edge 3a of the reinforcing frame 3. Therefore, the depth D of the case 1 can be made shallower than the conventional structure in which the case 1 is provided vertically (FIG. 4), and the bulk thereof can be reduced.

Further, it is possible to provide a large number of connector sections in a smaller area by arranging the connector sections 4, 5, 6 via the inclined step sections 2a ', 2b'.

The attachment and detachment of the electric functional parts such as the fuse 8 and the relay 9 at the time of maintenance can be performed obliquely with respect to the upper surface of the case 1 as shown by the arrow in FIG. It is sufficient if there is a work space corresponding to the height h 'at the time of the inclination lower than the height h.

Although the electric connection box A of the present invention is an example formed as a so-called fuse block (or relay block), the same operation is applied to a case where a wiring board such as a bus bar circuit board or a printed board is housed in the case 1. The effect is obtained.

FIG. 3 shows an example in which the electric connection box A of the present invention is screwed and fixed substantially horizontally to the console panel 10 of the instrument panel P of the automobile by using the screw holes 7 (note that the electric connection box A is also connected to the electric connection box A). The decorative cover to be put is not shown.)

In this case, the driver can easily attach and detach the electric function components such as the fuse 8 and the relay 9 from the front side while sitting down on the seat while looking down at all the electric functional components such as the fuse 8 and the relay 9.

[Effect of the invention]

As described above, according to the present invention, in an electric connection box in which a mounting surface having a connector portion for various electric functional parts such as a fuse and a relay is formed on an upper surface, a plurality of mounting surfaces are inclined in one direction and each of adjacent mounting surfaces is mounted. An inclined step portion is interposed between the surfaces, and the step portion of the mounting surface having the connector portion for the tall electric functional component is more than the step portion of the mounting surface having the connector portion for the short electric functional component. If it is formed large, a plurality of electric functional parts are provided at an angle to the reference plane of the case, so that the occupied space is made small, so that installation and maintenance in a narrow part of the vehicle are possible, and in addition,
Large and small electrical functional parts with different heights are rationally coupled to the connector part of the mounting surface with different steps, and the tall electrical functional parts are not particularly protruded, so that the electrical junction box is large and small. The space utilization efficiency can be greatly increased.
