Description

Module Type Junction Box

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a junction box used in an engine room of an automobile and used for distributing electric power to respective electric devices. More specifically, the junction box is modularized into a plurality of blocks, And a junction box using a single junction box.

BACKGROUND ART [0002] In general, a junction box is provided in an engine room of an automobile and a car room to distribute power to a plurality of electric devices provided in an automobile.

In the automobile, dozens of relays and fuses are provided. If such relays and fuses are arranged in a dispersed manner, the structure becomes complicated and control becomes difficult.

Accordingly, the relay and the fuse are integrated in one place, and the junction box is used as an apparatus for distributing power to each electric device module.

The junction box described above is manufactured in various structures, and FIGS. 1A to 1C show an example of a conventional junction box.

However, in the conventional junction box, a separate junction box must be manufactured for each project and option at the design and development stage.

As a result, there is a problem in that cost and manufacturing cost are increased in the design and development stages.

The conventional junction box is manufactured as a PCB (Printed Circuit Board) relay module type as shown in FIG. 1A, or as a plug-in relay type as shown in FIG. 1B.

The PCB relay module type is a method of arranging a plurality of relays on a PCB and indirectly connecting the relays.

In addition, the plug-in relay type is a method of directly connecting each of the conductive terminals and the electric elements using a female / male connector without using a PCB.

Accordingly, the plug-in relay (R) can not be used for the PCB relay module type junction box, and the PCB relay module (M) can not be used for the plug-in relay type junction box.

1C, since the structure of the bus bar B used for distributing the power varies depending on the layout of the relays, it can not be used in compatibility with different projects and options There are disadvantages.
