Abstract
The present invention relates to multifuse. In the multi-fuse 10 of the present invention, the fuse body 11 forms an appearance and a skeleton. An inner space is formed inside the fuse body 11, and the inner space communicates with the lower portion of the fuse body 11 through a communication slit. The inner space is opened to the upper portion of the fuse body 110 to form a confirmation window 12. A cover 14 of transparent or translucent material is installed to shield the confirmation window 12. The fuse body 11 A connecting terminal 16 is connected to the power source so as to protrude to the outside of one side thereof, and the connecting legs 20 are disposed to protrude out of the fuse body 11 through the communication slit. The bus bar 22 is installed in the fuse body 11 so as to face a part of the connecting leg 20, and the upper end of the connecting leg 20 is connected to each other. A melting end 24 is installed at a position corresponding to the confirmation window 12 corresponding to the upper end of the bus bar 22. The melting end 24 is melted and broken when the component is overloaded. The melted portion 24 is connected to the bus bar 22 through a first connecting portion 26. The connecting leg 20 is connected to the connecting leg 20 through the second connecting part 28. According to the present invention having the above configuration, the melting part 24 is formed in the confirmation window 12 which is formed to open to the upper portion of the fuse body 11. Since it is in the corresponding position, the operator can easily check the state of the melted portion (24).
Description
The present invention relates to a multi-fuse, and more particularly to a multi-fuse to be able to check the state of the melt portion on the upper surface of the fuse body.
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.
1 is a front view showing the configuration of a multifuse according to the prior art. According to this, the multi-fuse 1 supplies power to a plurality of electrical appliances, and serves to prevent overcurrent from flowing to each of the electrical appliances. The multi-fuse 1 mainly supplies power to the electrical appliances used basically, and supplies power to the electrical appliances requiring large currents. The
In the
Both ends of the
However, the multi-fuse according to the prior art having the configuration as described above has the following problems.
In the multi-fuse 1 according to the prior art, a blowout part is provided inside the
Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide a multi-fuse capable of checking the state of the melt portion provided therein while being mounted in the box.
According to a feature of the present invention for achieving the above object, the present invention communicates with the outside through a communication slit formed in the lower inner space of the fuse body and the upper side of the fuse body, the fuse body of the A transparent or translucent cover coupled to the confirmation window of the fuse body to shield the confirmation window, a connection terminal exposed to one side of the fuse body and connected to an external power source, and protrudes to the outside of the fuse body through the communication slit; A connection leg disposed to distribute power to each component, a bus bar connected to the connection terminal and positioned to face a portion of the connection leg in an internal space of the fuse body, and the bus bar and the connection leg respectively to a first portion. And connected through a second connection portion is installed in a position corresponding to the confirmation window of the fuse body and melted and broken when the part is overloaded It is configured to include an end.
The melted end is connected to the bus bar and the connecting leg by the first connecting part and the second connecting part at a position corresponding to the upper portion of the bus bar and each connecting leg.
The length of the first connecting portion and the second connecting portion is designed differently depending on the component to which the connecting leg is connected.
The fuse body has a flat hexahedron shape so that the confirmation window is opened upward.
The melt part is disposed at a position protruding from the confirmation window of the fuse body, and the cover has a hexahedron shape in which a lower portion coupled to the check window of the fuse body is opened to surround the fuse part.
The melted portion is disposed in an inner space corresponding to the confirmation window of the fuse body, and the cover has a plate shape in which an edge thereof is coupled to the fuse body so as to shield the confirmation window.
In the multifuse according to the present invention, the following effects can be obtained.
That is, in the present invention, since a confirmation window is formed on the fuse body of the multi-fuse, and the blow-out part is located inside the fuse body adjacent to the check window, the operator can check the state of the blow-out part with the multi-fuse installed in the box. There is an effect that the convenience is increased.
