The low voltage fuze drug consists of the components according to weight percentage: 70-80 of rare earth alloy, 18-28 of solid explosive that is uneasy to absorb the wet and be broken down and 1-2 of aluminium powder. The fuze of the invention is characterized in that: an insulated sleeve is filled with a low voltage fuze drug that is tightly pressed, one end of an electrode is fixed on the insulated sleeve and the other end thereof is buried in the low voltage fuze drug in the sleeve and the insulated sleeve is also provided with an igniting hole. After the fuze is input with low voltage, the low voltage fuze drug is ignited so as to ignite the explosive to be exploded. The invention has the advantages of novel concept, reasonable and compact structure, easy processing and production, fast speed, high efficiency, low volume, miniaturization, integration, wide application, safety and reliability with 100 percent of igniting success ratio, and the invention can bring the reformation of fire arms, reduce the weight of fire arms and improve shooting rate if the invention is applied to primer, shell, normal bullet and caseless ammunition and can do self-destroy protection if the invention is applied to a circuit or a memory.
Description
Technical field
The invention belongs to the fuse of fired charge, relate in particular to electric fuze medicine and fuse.
Background technology
In military, civilian blast or explosion, must adopt the fuse explosive that ignites.The percussion of bullet of tradition firearms is the ammunitions that ignite of the fire in a stove before fuel is added by firing lock bump bullet.Its defective is to use its firing lock complexity of firearms of this fire in a stove before fuel is added fuse, and volume is big, has increased the weight of firearms greatly; Shooter will exert to overcome the frictional force of hammer to the plate machine during shooting, and movement range is big, and trajectory can be pulled the plate machine with finger and produce skew when making percussion, and bullet trains off easily, has reduced the hit rate of pointing accuracy and shooting.And the fire in a stove before fuel is added of caseless cartridge adopts the capacitor discharge percussion at present, after must boosting through transformer, utilizes its high-voltage spark of emitting to light percussion charge.If use electric bridge silk fuse, because electric bridge silk fuse connects complicated, weld is many, and volume is big, also can be because of the influence of ambient conditionss such as vibrations, generation is opened circuit or loose contact, it is inaccurate to light a fire, even mistake combustion and explosion caused, reduce striking voltage, simplify shot-firing circuit, but do not have such electric fuze medicine so far.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this invention is to provide a kind of low voltage fusee powder, another purpose provides a kind of low voltage fuse, and striking voltage is low, and igniting is accurately, and is safe and reliable; This fuse structure is simplified, and volume is little, and easily processing easily realizes miniaturization, integrated.
Low voltage fusee powder, (%) by weight percentage, form by following component:
Rare earth alloy 70-80 is difficult for the solid explosive 18-28 of moisture absorption and decomposition, and aluminium 1-2 rare earth alloy, aluminium and explosive are Powdered, particle diameter 80-100 order, fully mixing.
The bulk density of firing voltage and powder is inversely proportional to, and bulk density characterizes powder and compresses degree here, presses to such an extent that tight bulk density is big, otherwise then loose.
Described rare earth alloy.It contains following component:
45-51% cerium, 23-26% lanthanum, 15-19% neodymium, 4-6% praseodymium, other rare earth metal 1-2%, Fe≤3%.
This rare earth alloy powder conductivity is better, and chemical property is active, and point of ignition is low, is good detonator.The shared ratio of its firing voltage and rare earth alloy powder is inversely proportional to, and ratio is big more, and firing voltage is low more.
Described moisture absorption and the decomposed explosive of being difficult for is Cyclotrimethylene trinitramine, TNT, one or more blended mixtures of the nitro-cotton after peace, the acetone plasticizing too, plays combustion-supporting effect.
Aluminium powder works to prevent that rare-earth metal powder is oxidized.
The characteristics of low voltage fuse are that low voltage fusee powder is filled in the insulation thimble, compresses, and are lower than 20 Ω to two interpolar resistance values.Electrode one end is fixed on the insulation thimble, and the other end is imbedded in the interior low voltage fusee powder of insulation thimble, and insulation thimble also is provided with flash hole.During use, add direct supply, pressing button, low-tension current flow through low voltage telecommunications medicine, light the fuse medicine, thereby high-temperature gas is lighted ammunition by the flash hole spray, make bullet percussion or blasting cap detonation.
The present invention further improves, and the low voltage fusee powder filling is in insulation tube, and the sheet pole piece is pressed on the low voltage fusee powder, and the porcelain big envelope is on insulation tube, and pellet electrode is fixed in the porcelain envelope of two ends, and utmost point pin is fixed on porcelain and seals up.Two interpolar pin resistance are less than 20 Ω, shape such as resistance element.
Another improves the present invention, and the low voltage fusee powder filling is compressed by insulating plug in the housing of shape such as electric capacity shell, insulating plug is installed in the bayonet socket of housing, electrode passes insulating plug and imbeds in the low voltage fusee powder, and utmost point pin is fixed on insulating plug, and two interpolar resistance are less than 20 Ω.Shape such as capacity cell.
Compared with prior art, advantage is:
1, novel, structural reduction, reasonable, compact, material source is wide, is easy to processing and fabricating, and process velocity is fast, the efficient height;
2, the fuse volume is little, is easy to miniaturization and integrated, and purposes is wide, is applied on detonator, shell, common cartridge and the caseless cartridge, can cause rifle, bombard the reform of sending out mechanism, alleviates the weight of firearms; Be used for electronic circuit, can carry out the self-destruction protection circuit or the storer that is loaded with classified papers;
3, safe and reliable, striking voltage only between the 12-20V, belongs to safety voltage; Because of low voltage fusee powder contains metal-powder, shift static, can be because of static does not miss combustion, ignition success rate is up to 100%.
4, adopt electric fuze, firearms weight saving, firmly little during percussion, finger is clicked and is got final product, and improves fire accuracy, improves the hit rate of bullet, helps improving soldier's fighting capacity.
