For above-mentioned technical problem in the related technology, the utility model proposes a kind of fuses, can overcome existing skill
The above-mentioned deficiency of art.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of fuse, including fuse ontology, the fuse ontology includes insulation shell, the two side ends of the insulation shell
It is arranged with termination electrode, fuse equipment and insulating barrier are respectively arranged in the insulation shell, one end of the fuse equipment is worn
The through-hole crossed on insulating barrier is connect with the termination electrode inner wall of the insulation shell side, and the other end of the fuse equipment connects bullet
The termination electrode inner wall of the one end of spring in a stretched state, the other end of the spring in a stretched state and the insulation shell other side connects
It connects；Wherein, the fuse equipment includes fuse one and fuse two, and two parallel connection of fuse is wrapped on fuse one.
Further, the material of the insulating barrier is silica gel.
Further, one end of the fuse equipment passes through the end electricity of through-hole and the insulation shell side on insulating barrier
Pole inner wall is welded to connect by scolding tin.
Further, the other end of the spring in a stretched state and the termination electrode inner wall of the insulation shell other side pass through weldering
Tin welding connection.
Further, the material of the fuse two is high fusing thermal energy value material.
Further, one material of fuse is high resistivity material.
The utility model has the beneficial effects that in the fusing process of fuse, parallel-connection structure is provided using the utility model
A plurality of starting the arc channel is made simultaneously because the insulating properties of material of insulation silica gel partition itself can play blocking limitation to electric arc
With, and since the retraction of spring acts on, the fuse equipment that can quickly disconnect is further ensured that quick breaking arc and safe
Fusing, to guarantee people's safety of life and property.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, a kind of fuse according to the utility model embodiment, including fuse ontology, it is described
Fuse ontology includes insulation shell 1, and the two side ends of the insulation shell 1 are arranged with termination electrode 2, is set respectively in the insulation shell 1
It is equipped with fuse equipment and insulating barrier 4, one end of the fuse equipment passes through through-hole 8 and the insulation shell 1 on insulating barrier 4
2 inner wall of termination electrode of side connects, the one end of the other end connecting spring 7 of the fuse equipment in a stretched state, the bullet
The other end of spring 7 in a stretched state is connect with 2 inner wall of termination electrode of 1 other side of insulation shell；Wherein, the fuse equipment includes
Fuse 1 and fuse 26,26 parallel connection of fuse are wrapped on fuse 1.
In one embodiment, the material of the insulating barrier 4 is silica gel.
In one embodiment, one end of the fuse equipment passes through through-hole 8 and the insulation shell on insulating barrier 4
2 inner wall of termination electrode of 1 side is welded to connect by scolding tin 3.
In one embodiment, the termination electrode of the spring 7 other end in a stretched state and 1 other side of insulation shell
