Description
The present invention relates to a high voltage fuse, and more particularly, to a high voltage fuse in which an arc extinguishing material is filled inside to prevent generation of secondary arcs during cutting of the melt part, and thus the filling of the arc extinguishing material is more easily performed.
The fuse is to supply power to the electronic components from a power source such as a battery, and to cut off the power supply quickly when the electronic components are overloaded. Some of these fuses are used in electrical components where high voltage is used. The fuse used at high voltage can be secondarily impacted on the electric component by the power supplied to the electric component through the arc generated when the fuse of the fuse is melted and broken due to the overload.
In order to solve such a problem, it is necessary for the fuse used at high voltage to cut off the arc generated when the blown part is broken. To this end, a small material such as sand is filled in the space in which the melted portion is accommodated to surround the melted portion.
However, the work of filling the arc extinguishing material in the space in which the melted part is accommodated is very troublesome. In order to fill the inner space of the fuse without gaps, it is preferable that the arc extinguishing material is sand, but it is preferable to do so in a state in which the housing and the fuse terminal are completely coupled. Since the SOHO material is not completely filled in the housing, there is a problem that the SOHO performance decreases due to a slight empty space inside the housing, and in this case, it is inconvenient to prevent the input port by using a separate structure such as a fastening ring. there was.
Therefore, an object of the present invention is to solve the conventional problems as described above, in the insulating housing that is slidingly coupled to each other between the hoses of the inner space of the insulating housing by placing the filling portion to enter the inner space when the insulating housing is coupled There is no gap in the.

The thickness of the blocking plate is longer than the movement information of the first insulating housing and the second insulating housing which allow the opening to be opened and closed by the first end cap.
The interference avoiding part is formed by removing the tip of the blocking plate in a thickness direction to some extent, and the filling part is located in the interference avoiding part, and the interference when the first insulating housing and the second insulating housing are completely combined. The length is set to protrude from the avoiding part to the inner space of the insulating housing.
A filling part is formed on an inner surface of the end side wall of the first end cap of one side of the first insulating housing, and an interference avoiding part is formed on the blocking plate of the second end cap of the second insulating housing corresponding thereto, and the other side of the first insulating housing. An interference avoiding part is formed on the blocking plate of the first end cap, and a filling part is formed on an inner surface of the end side wall of the second end cap of one side of the second insulating housing corresponding thereto.
According to another feature of the invention, the present invention comprises a first insulating housing having a first end cap is provided at both ends of the first body portion and having an uneven coupling portion extending in the longitudinal direction at both ends, and the first insulating housing An inner space having a concave-convex coupling portion coupled to the concave-convex coupling portion and having a second end cap disposed at both ends of the second body portion and being relatively moved in the longitudinal direction with respect to the first insulating housing, A second insulating housing formed in cooperation with the first insulating housing, the first connecting portion and the second connecting portion protruding from both ends of the first and second insulating housings in the longitudinal direction of the first and second insulating housings, and are provided in the inner space to overload. And a fuse terminal having a melted portion that is melted and broken at a time, and the interference avoiding portion and the interference avoiding portion are formed at positions corresponding to each other of the first end cap and the second end cap. It is formed to have a longer length and is provided with a filling portion that protrudes into the inner space when the first insulating housing and the second insulating housing are completely coupled, and one of the second end caps is formed with an inlet shielded by the first end cap. After the filling material is filled into the inner space through the inlet, the first and second insulating housings are moved relative to each other in the longitudinal direction to shield the inlet, and the filling part enters the inner space from the interference avoiding part. Reduces the volume of
The first end cap and the second end cap are each provided with a blocking plate on an end side wall, and the blocking plate is formed to have a thicker thickness than the other parts of the first insulating housing and the second insulating housing, respectively. The thickness of the blocking plate is longer than that of the relative moving row information between the first insulating housing and the second insulating housing which allow the opening to be opened and closed by the first end cap.
The interference avoiding part is formed by removing the tip of the blocking plate in the thickness direction, and the filling part is set in length such that a part is located in the interference avoiding part and the remaining part protrudes into the inner space of the insulating housing.
