The present invention relates to a fuse box, and more particularly, to a fuse box having a fuse which is supplied with power and supplied to each of the electrical appliances to prevent overcurrent flow to the electrical component.

There are many different electronics that use power in a vehicle. For example, there are a motor, a spark plug, and the like. These electronics require power for their operation. These electronics are supplied from a battery or generator through a fuse box.

The fuse box is provided with a fuse that prevents an overcurrent from flowing through the respective electrical appliances. Therefore, while the electric power is supplied to each electric appliance through the fuse, when the overcurrent flows, the fuse is blown to cut off the power supply to the electric appliance.

However, the conventional fuse box as described above has the following problems.

First, for example, the number of electrical appliances used in a vehicle tends to increase gradually. Therefore, the number of fuses to be disposed in the fuse box also increases gradually. As such, when the number of fuses increases, it becomes difficult to install them in the fuse box one by one, and there is a problem in that assembly of the fuse box is deteriorated.

In particular, conventionally, because of the use of one fuse in one electronic device, it is difficult to distinguish between the electronic device used in the vehicle and the fuse used in the electronic device provided as an option. There is a problem that consumes.

In addition, since a component mounting part for mounting a large number of fuses, respectively, must be formed for each fuse, there is a problem in that the size of the component box is increased.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a fuse box having a relatively small number of fuses.

Another object of the present invention is to provide a fuse box employing a multi-fuse in which the fuse for the electrical equipment used basically.

Still another object of the present invention is to provide a fuse box using the same power terminal to supply power to the multi-fuse and the mini-fuse.

According to a feature of the present invention for achieving the object as described above, the present invention is a main body having a plurality of component mounting portion, and is mounted to the component mounting portion to supply power to a plurality of electrical appliances and to block the flow of overcurrent A multi-fuse, a mini-fuse mounted on the component mounting unit and supplying power to each electric component and blocking the flow of overcurrent, and a connection part installed to penetrate the main body up and down and electrically connected to an external power source; And a bus bar for supplying power to the mini-fuse side of the main body, and a bus bar installed at the main body and electrically connected to the connection bus bar to supply power to the mini-fuse.

The multi-fuse is a fuse body having a configuration for blocking the overcurrent therein, a connection leg extending to the outside of the fuse body and electrically connected to each electrical appliance, and protruding on both sides of the fuse body is formed It comprises a first and second connection terminals connected to the external power source.

On both sides of the main body, the distribution connection part is formed to penetrate up and down, and the distribution connection part is provided with a fastening nut fastened to one side coupling part having a coupling part formed at both ends of the seating end, and the other coupling part of the second bolt. The connection part of the connection bus bar and the first or second connection terminal and a power terminal electrically connected to an external power source are installed in turn and are coupled to a separate fastening nut.

The bus bar has a connection part electrically connected to the connection bus bar on one side, and a terminal part electrically connected to the minifuse is formed on the other side.

The main body is formed such that the wire escape portion through which the wire connected to the power terminal passes.

The multi-fuse supplies power to the electronics used basically.

The mini-fuse has a smaller power supply capacity than the multi-fuse.

The fuse box having a multi-fuse according to the present invention having such a configuration can reduce the total number of fuses and the number of component mounting parts to which the fuse is mounted since one multi-fuse is used for the electrical components used basically. It can be reduced to improve assembly workability and to reduce the size of the fuse box.

In addition, since one multi-fuse is used for the electronics that are basically used, the operator must install the multi-fuse in the fuse box and selectively install only the optional fuse, so the fuse installation work is relatively easy. Since external power is supplied through the power terminal and divided into multifuse and minifuse through the bus bar, the power supply structure is relatively simple and the power supply is stable.
