Inside, wherein, upper end electrode 3 is located at the top of cartridge fuse 2, and is connected with cartridge fuse 2, and lower end electrode 5 is located under cartridge fuse 2
Side, and be connected with cartridge fuse 2.So, upper end electrode 3, lower end electrode 5 and cartridge fuse 2 are respectively positioned on the inside of fuse 1,
The structure of all insulation can be realized, the reliability of fuse is improved.
Specifically, upper end electrode 3 is connected with upper outlet lead 4, and upper outlet lead 4 is drawn outside fuse 1, lower end electricity
Pole 5 is connected with lower outlet lead 6, and lower outlet lead 6 is also drawn outside fuse 1.
In specific scheme, upper seal 8 has been formed integrally with the top portion in fuse 1, the upper seal 8 have with
The lead channels of the upper lead outlet connection of fuse 1, upper outlet lead 4 is formed directly into after the stretching of upper lead outlet
The lead channels of seal 8, so, upper outlet lead 4 stretch out fuse 1 by the upper seal 8 with lead channels
Outside.
Lower seal 9 is formed with the portion integral of fuse 1, the lower seal 9 has and fuse 1
The lead channels of lower lead outlet connection, lower outlet lead 6 is formed directly into the lead of lower seal 9 after the stretching of lower lead outlet
Passage, so, lower outlet lead 6 are stretched out outside fuse 1 by the lower seal 9 with lead channels.
Wherein, the lower end for being opened in fuse 1 of cartridge fuse 2 will be generally loaded and unloaded, on the one hand facilitates cartridge fuse 2
Handling, another convenience can prevent the entrance of the pollutant such as dust as far as possible, on this basis, outer lead outlet is opened in molten
The side wall of the disconnected bottom of device body 1, as shown in Figure 1, it will be understood that after so setting, the center of upper seal 8 and lower seal 9
Line is mutually perpendicular to.
Specifically, upper seal 8 and lower seal 9 are integrally formed rubber, are on the one hand conducive to keeping insulating properties,
On the other hand it is easy to machine-shaping.
Specifically, upper seal 8 and lower seal 9 are included close to the inner section of fuse 1 and away from fuse
The outer portion part of body 1, as shown in figure 1, wherein, the section of inner section is gradually reduced from inside to outside, the cross-sectional sizes one of outer portion part
Cause, that is to say, that upper seal 8 and lower seal 9 are larger size, Neng Gouti with the part that fuse 1 is connected
The reliability of height connection.
More specifically, as illustrated, the roughly triangular knot of the section of the inner section of upper seal 8 and lower seal 9
Structure.
