Drawings
FIG. 1 is a schematic view of the overall structure of a low-voltage fast fuse of the present invention;
fig. 2 is the internal structure diagram of the low-voltage fast fuse of the present invention.
The fuse protector comprises a fuse protector protection box 1, a conductive connector 2, a fixing bolt 3, an insulating protection frame 4, a conductive connecting plate 5, a fuse link 6 and a fuse link.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments, and the technical features or the connection relations of the present invention, which are not described in detail, are the prior art adopted.
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, the technical scheme adopted by the utility model is as follows: the utility model provides a low pressure fast acting fuse, includes fuse guard box 1, electrically conductive connector 2, fixing bolt 3, insulating fender bracket 4, electrically conductive connecting plate 5 and fuse-link 6, insulating fender bracket 4 is located on fuse guard box 1, fuse guard box 1 is the cavity type cuboid setting in both ends opening form, fuse guard box 1's bottom is located to electrically conductive connector 2, fixing bolt 3 is located on electrically conductive connector 2, electrically conductive connecting plate 5 is located on electrically conductive connector 2, fuse-link 6 is located on electrically conductive connecting plate 5, fuse-link 6 is the cuboid setting.
The conductive connecting plates 5 are provided with three groups, and the conductive connecting plates 5 are arranged in an arched rectangular shape.
The fuse links 6 are provided with two groups, the two groups of fuse links 6 are arranged between the three groups of conductive connecting plates 5, a plurality of diamond-shaped small holes are formed in the fuse links 6, and the distances among the diamond-shaped small holes are equal.
The insulation protection frames 4 are arranged in two groups, and the insulation protection frames 4 are arranged in an inverted L shape.
When the fuse protector is used specifically, a user holds the insulating protection frame 4 to enable the conductive connector 2 to face downwards, then the conductive connector 2 is inserted into a device needing power-off protection, such as a switch, a socket and the like, after the switch, the socket and the like are powered on, current is transmitted to the conductive connecting plate 5 through the conductive connector 2, heat is generated in the process of current flowing, the larger the current is, the larger the heat is, when the heat rises, the conductive connecting plate 5 generates plastic deformation under the action of high temperature, the arc-shaped conductive connecting plate 5 is adopted to counteract the plastic deformation generated by high temperature at the arc-shaped position to protect the fuse at high temperature, then the current continues to flow to the fuse link 6, a plurality of diamond-shaped small holes are formed in the fuse link 6, the distances between the small holes are the same, the resistance is the same when the current flows through the fuse link 6, and the temperature is too high when the, when the temperature of the current on the fuse link 6 is higher than the melting point of the fuse link 6, the distance between the small holes on the fuse link 6 starts to be disconnected, when a small distance starts to be short, the resistance increases along with the short distance, and the distance between the rest small holes is quickly disconnected, so that the current loses a transmission medium, the purpose of power-off protection is achieved, and the whole working process of the fuse is just the working process.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
