Description
Technical field
The utility model is related to a kind of circuit accessory technical field, the parallel resistance insurance of fusing more than more particularly to a kind of safety
Silk.
Background technology
Fuse is also referred to as fuse, and it is a kind of installs in circuit, it is ensured that the electric elements of circuit safety operation
Tube fuse is general by end metal electrode, insulation shell and fuse composition, and fuse and end metal electrode are to ensure electricity by scolding tin
Gas connection：But existing tube fuse in the circuit installed in 500V, 600V or 1000V when, when circuit occur
Failure or he it is abnormal when, fuse understands itself fusing, but because circuit voltage is higher, had inside insulation shell electric arc produce and
It is not easy to be to go out, and temperature and air pressure inside insulation shell is drastically raised, then fuse can explodes and on fire, surpass into property
Loss and the generation of security incident.Therefore, a kind of it is proposed that parallel resistance fuse that fused safety more.
Utility model content
Main purpose of the present utility model is to provide fusing parallel resistance fuse more than a kind of safety, can effectively solved
The problem of in background technology.
To achieve the above object, the technical scheme that the utility model is taken is：
Fuse parallel resistance fuse more a kind of safety, including metal electrode, insulating glass pipe and fusible link, the metal
Electrode side, which is provided with inside wire, the wire, is provided with resistance, and insulating glass pipe and fusible link are provided with inside the metal electrode,
And fusible link is located inside insulating glass pipe, the fusible link two ends are provided with fixed scolding tin and insulating barrier, and insulating barrier position
Between fixed scolding tin.
Further, it is provided with fuse fixing hole inside the insulating barrier.
Further, the fixed scolding tin is fixedly connected with metal electrode.
Further, the fusible link material is lead-antimony alloy.
Further, the insulating barrier material is silica gel.
Compared with prior art, the utility model has the advantages that：By two resistance in parallel, because resistance belongs to pole
Group inductance.It can pass through resistance more than 300v voltage instantaneous.Fuse is avoided because electric current is excessive and bursts.In especially big short-circuit conditions
Lower resistance plays certain shunting action in order to avoid fuse glass breaking, resistance manufacturing process Luo Xuan laser scorings type into, in 10ns
In peak pulse voltages by resistance, be exactly isobaric shunting the characteristics of parallel circuit.

Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the utility model realization, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1-2, fuse parallel resistance fuse more a kind of safety, including metal electrode 1, the and of insulating glass pipe 2
Fusible link 4, the side of metal electrode 1 is provided with wire 7, and the inside of wire 7, which is provided with inside resistance 6, the metal electrode 1, to be set
There are insulating glass pipe 2 and fusible link 4, and fusible link 4 is located inside insulating glass pipe 2, the two ends of fusible link 4 are welded provided with fixed
Tin 3 and insulating barrier 5, and insulating barrier 5 is between fixed scolding tin 3.
Fuse parallel resistance fuse more a kind of safety of the utility model, by two resistance in parallel, because resistance belongs to minimum
Class inductance.It can pass through resistance more than 300v voltage instantaneous.Fuse is avoided because electric current is excessive and bursts.Under especially big short-circuit conditions
Resistance plays certain shunting action in order to avoid fuse glass breaking, resistance manufacturing process Luo Xuan laser scorings type into, in the 10ns times
Interior peak pulse voltages are exactly isobaric shunting the characteristics of parallel circuit by resistance.
Wherein, the inside of insulating barrier 5 is provided with fuse fixing hole 8.
Wherein, the fixed scolding tin 3 is fixedly connected with metal electrode 1.
Wherein, the material of fusible link 4 is lead-antimony alloy.
Wherein, the material of insulating barrier 5 is silica gel.
It should be noted that the utility model is fusing parallel resistance fuse more than a kind of safety, two ends are provided with metal electricity
Pole 1, inside is fixed with insulating glass pipe 2.Provided with two fusible links 4 in insulating glass pipe 2, and entirety is in series with two resistance 6,
When short circuit occurs in circuit, the fusing of fusible link 4 plays a protective role, the overtension of contingency.Can be direct higher than 300v voltages
Fusible link is protected by resistance 6.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
