Description
Foreliggende oppfinnelse angår en komponent for tennlegeme med detoneringslunte, omfattende et hult, metallisk legeme, et keramisk legeme montert inne i det metalliske legeme, en pyroteknisk ladning, en detonerende luntetenner i kontakt med samme inne i det metalliske legeme, første og andre parallelle metallstifter festet inne i det keramiske legeme og innrettet for til-kobling til en spenningskilde. The present invention relates to a component for an igniter with a detonating fuse, comprising a hollow metallic body, a ceramic body mounted inside the metallic body, a pyrotechnic charge, a detonating fuse igniter in contact with the same inside the metallic body, first and second parallel metal pins attached inside the ceramic body and arranged for connection to a voltage source.
Tennlegemet har i den ene ende sikkerhets-gnistbanen og The ignition body has the safety spark path at one end and
de deler som er nødvendige for tilførsel av den elektriske energi for denne tenningstype (pulser med høy energi) og i den annen the parts necessary for supplying the electrical energy for this type of ignition (pulses with high energy) and in the other
ende detoneringslunten og tennsatsen, det hele innesluttet i tennlegemet. Det er også sørget for en meget god kontakt mellom dem i området hvor de møtes. end the detonation fuse and the igniter, the whole enclosed in the igniter body. It has also been ensured that there is very good contact between them in the area where they meet.
Lignende anordninger forsåvidt angår tenningsenergi, Similar devices insofar as they relate to ignition energy,
men som ikke omfatter en kontinuerlig løsning, vil kunne ødelegges eller nøytraliseres under påvirkning av konsekutive ukontroller-bare spenninger, f.eks. i elektromagnetiske områder. but which does not include a continuous solution, will be able to be destroyed or neutralized under the influence of consecutive uncontrollable stresses, e.g. in electromagnetic fields.
De kjente anordninger som omfatter en kontinuerlig løs-ning, omfatter som oftest en koaksial anordning av sikkerhets-gnistbanen, hvilket hindrer en finregulering av tennspenningen på grunn av fabrikasjonsvanskeligheter som skyldes det prinsipp som ligger til grunn for denne anordning, og er beheftet med en sterk spredning av spenningsterskelen (som kan variere opp til det dobbelte) og som i alminnelighet er meget generende og endog kan være helt uakseptable for visse anvendelser. The known devices which include a continuous solution, most often include a coaxial device of the safety spark path, which prevents a fine adjustment of the ignition voltage due to manufacturing difficulties due to the principle underlying this device, and is burdened with a strong spread of the voltage threshold (which can vary up to twice as much) and which is generally very annoying and can even be completely unacceptable for certain applications.
Anordningen ifølge oppfinnelsen gjør det mulig å elimi-nere de nevnte ulemper, men allikevel sikre en god virkning under meget vanskelige forhold, og utmerker seg ved en hul hylse festet i det keramiske legeme forsynt med en gjengeboring med lengdeakse koaksialt med den for den første stift, en gjenget metallisk regulerbar stift skrudd inn i boringen, idet den ene ende av den regulerbare stift er i en innstillbar avstand fra en ende av den nevnte første metalliske stift for å frembringe et gnisttap mellom dem, hvorved det opprettes en tennings- og prøvekrets gjennom den første metalliske stift, det nevnte gnisttap, den innstillbare stift, detoneringslunten, den annen metalliske stift som gjør det mulig å innstille den nøyaktige spenningsterskel for gnisttapet ved å kople en energikilde til endene av nevnte krets og dreie på den innstillbare stift. The device according to the invention makes it possible to eliminate the aforementioned disadvantages, but still ensure a good effect under very difficult conditions, and is distinguished by a hollow sleeve fixed in the ceramic body provided with a threaded bore with a longitudinal axis coaxial with that of the first pin , a threaded metallic adjustable pin screwed into the bore, one end of the adjustable pin being at an adjustable distance from one end of said first metallic pin to produce a spark loss between them, whereby an ignition and test circuit is established through the first metallic pin, the said spark loss, the adjustable pin, the detonation fuse, the second metallic pin which makes it possible to set the exact voltage threshold for the spark loss by connecting an energy source to the ends of said circuit and turning the adjustable pin.
Denne anordning sikrer montasjen og den stive forbin-delse i et metall-legeme av herdet stål og den omfatter i en ende et spenningsuttak som er låsbart forbundet med det elektriske kraftnett; den annen ende er reservert for innkapslingen av den pyrotekniske ladning og for tennhettens mekaniske forbindelser med de ytre konstruksjonsdeler. This device ensures the assembly and the rigid connection in a metal body of hardened steel and it comprises at one end a voltage outlet which is lockably connected to the electrical power grid; the other end is reserved for the encapsulation of the pyrotechnic charge and for the ignition cap's mechanical connections with the external structural parts.
Den sentrale del omfatter en understøttelse av metalli-sert keramikk, i hvilken der er festet to metallstifter av en ferro-nikkellegering, av hvilke den ene inneholder gnistbanen som er anordnet på en sådan måte at det er mulig under montasjen å regu-lere spenningsterskelen for dens funksjon. Denne detonerings-spenning reguleres ved hjelp av en høyspenningsgenerator. Regule-ringen av mellomrommet mellom elektrodene oppnås ved regulering av elektrodeskruen for et skrue-muttersystem. The central part comprises a support of metallised ceramics, in which two metal pins of a ferro-nickel alloy are attached, one of which contains the spark path which is arranged in such a way that it is possible during assembly to regulate the voltage threshold for its function. This detonation voltage is regulated by means of a high-voltage generator. The regulation of the space between the electrodes is achieved by regulation of the electrode screw for a screw-nut system.
Keramikk-metallforbindelsene er sikret ved sveising The ceramic-metal connections are secured by welding
eller lodding. Detoneringslunten er en platinalunte som er forbundet med endene av stiftene ved tinnlodding. or soldering. The detonating fuse is a platinum fuse connected to the ends of the pins by tin soldering.
Tegningen visertskjematisk et snitt av et utførelses-eksempel på en anordning ifølge oppfinnelsen. The drawing schematically shows a section of an embodiment of a device according to the invention.
Anordningen omfatter et keramisk legeme som ved lodding fastholdes i et metall-legeme 2 av herdet stål. Det keramiske legeme inneslutter forbindelsesstifter 3 og også en anordning 4 The device comprises a ceramic body which, by soldering, is held in a metal body 2 of hardened steel. The ceramic body includes connecting pins 3 and also a device 4
for regulering av spenningen for gnisttapets funksjon. Disse deler er sveiset til det keramiske legeme over metalliserte områder. for regulating the voltage for the spark loss function. These parts are welded to the ceramic body over metallized areas.
Anordningen i henhold til oppfinnelsen er hovedsakelig beregnet til utførelse av elektro-pyrotekniske anordninger med detoneringslunte og har en særdeles høy sikkerhet (ifølge sitt prinsipp og ifølge utførelsen). Den kan også finne anvendelse The device according to the invention is mainly intended for making electro-pyrotechnic devices with a detonating fuse and has a particularly high level of safety (according to its principle and according to the design). It can also find application
på vitenskapelige områder, såsom ved undersøkelse av plasmaer, mikrofotografier osv. in scientific areas, such as when examining plasmas, photomicrographs, etc.
