Description
Technical field
The utility model relates to fuse technical fields, and in particular to a kind of anti-lightning composite fuse wire.
Background technique
Multi line insurance is commonly used in the small-power electronics product such as phone charger, power supply adaptor, small household appliances, electronic toy
Silk, overcurrent and temperature protection can be provided for product, in use, can be prevented because product operation irregularity or environment temperature are different
Product overheat, casing deformation, kindling caused by often etc..But traditional insurance resistance, two-in-one resistance, composite fuse wire produce
Product, anti-lightning voltage can only achieve 1.7KV or so, be not suitable for using under severe thunder and lightning environment, it is easy to be damaged, up to not
To higher lightning stroke requirement.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed
Reason, anti-lightning composite fuse wire easy to use.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes by resistance wire, ceramic bar construction
Resistance wire ontology；The both ends of ceramic rod are equipped with resistance lead；Resistance lead is electrically connected with resistance wire；Resistance wire is close to be wound on ceramic rod
Middle part；Explosion-proof skin of paint is enclosed on the outside of resistance wire ontology；High explosion-proof anti-2KV lightning stroke is enclosed on the outside of explosion-proof skin of paint
Oxidation film layer；
Preferably, resistance wire it is close around spacing be twice of resistance wire diameter or three times resistance wire diameter.
After adopting the above structure, the utility model has the beneficial effect that anti-lightning composite fuse wire described in the utility model,
It is strong to bear lightning stroke voltage capability, and by the double shielding of explosion-proof skin of paint, oxidation film layer, the physics that resistance wire generates is become
Change has stronger inhibiting effect, and explosion-proof performance is high, and has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of the utility model；
Fig. 3 is the schematic cross-section of resistance wire ontology.
Description of symbols:
1, ceramic rod；2, resistance wire；3, explosion-proof skin of paint；4, high explosion-proof anti-2KV lightning stroke oxidation film layer.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to shown in Fig. 1-2, present embodiment the technical solution adopted is that: it includes by resistance wire 2, ceramic rod 1
The resistance wire ontology of composition；The both ends of ceramic rod 1 are equipped with resistance lead；Resistance lead is electrically connected with resistance wire 2；Resistance wire 2 is close
It is wound on the middle part of ceramic rod 1；Explosion-proof skin of paint 3 is enclosed on the outside of resistance wire ontology；The outside of explosion-proof skin of paint 3 is enclosed with height
Explosion-proof anti-2KV lightning stroke oxidation film layer 4；
Referring to Fig. 3 shown in, resistance wire 2 it is close around spacing H be twice of resistance wire diameter or three times resistance wire diameter；
Explosion-proof skin of paint 3 by polyether polyol, polyester polyol and diphenyl methane -4,4'- diisocyanate or its change
The reactant and amine terminated polyether of property object, diethyl toluene diamine, pigment, auxiliary agent, diluent, fire retardant, antioxidant, resist it is quiet
Electric agent and silane coupling agent composition；
High explosion-proof anti-2KV lightning stroke oxidation film layer 4 includes metal powder one, metal powder two, fuel and solvent；Metal powder
End one, metal powder two can be that metal is tungsten, nickel, titanium, zinc, copper or silver powder, the ingredient and metal powder one of metal powder one
It is different；Fuel is thiocarbamide, urea, glycine, citric acid or these combination；Solvent is water, alcohol, hydrogen peroxide or these group
It closes.
In present embodiment, the diameter of ceramic rod 1 is 3.2mm, length 8.5mm.
The resistance wire 1 of all specifications is all made of ceramic rod by anti-lightning composite fuse wire described in present embodiment
It is intermediate it is close around method, it is close around spacing H be twice of resistance wire diameter or three times resistance wire diameter, when lightning stroke voltage is interim,
Middle a part lightning stroke voltage path is to be guided by resistance wire 1 by resistance wire, and another part is struck by lightning voltage path then by between pitch
Electric discharge consumes, to avoid resistance wire 1 because bearing stronger lightning stroke voltage to its fracture；
Since resistance wire is when by powerful lightning stroke voltage, the local moment of resistance wire can be in physical deformation, this change
Shape speed is exceedingly fast, if inhibiting to protect without extraneous special protective layer, it is easy to be struck off.In order to realize higher lightning stroke
It is required that being enclosed with explosion-proof skin of paint 3 on the outside of resistance wire ontology, high explosion-proof anti-2KV lightning stroke oxidation film layer 4 carries out the double-deck guarantor
Shield, the physical change generated to resistance wire has stronger inhibiting effect, and explosion-proof performance can also exceed professional standard.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the scope of the claims of the utility model.
