Description

BESCHREIBUNG DESCRIPTION
Anzündmittelignition devices
Die Erfindung betrifft ein Anzündmittel insbesondere für die Treibladung einer Munition.The invention relates to an igniter, in particular for the propellant charge of ammunition.
Aus der DE 199 28 832 A1 ist eine elektrische Anzündeinrichtung für die Treibladung einer Patrone bekannt, bei der unter Ausnutzung des elektromagnetischen Übertragungsprinzips die Anordnung vereinfacht und verbessert werden soll.From DE 199 28 832 A1 an electric ignition device for the propellant charge of a cartridge is known, in which the arrangement is to be simplified and improved by utilizing the electromagnetic transmission principle.
Ein gekapseltes elektrisches Anzündmittel wird in der DE 38 12 958 A1 beschrieben. Zur Vermeidung von Funktionsstörungen, die durch hochfrequente Störenergie ausgelöst werden können, wird vorgeschlagen, die herkömmliche Metallring- Haltescheibe für einen Bör- delverschluss des Hülsen- Fußendes durch eine scheibenförmiges Dielektrikum zu ersetzten.An encapsulated electrical igniter is described in DE 38 12 958 A1. To avoid malfunctions that can be triggered by high-frequency interference energy, it is proposed to replace the conventional metal ring holding disc for a Börel del closure of the sleeve foot end by a disc-shaped dielectric.
Das in der DE 39 02 617 A1 offenbarte Anzündsystem beschäftigt sich mit einem verbesserten Anzündverhalten, dass durch eine zwischen Zündquelle und Anzündsatz angeordnete Scheibe aus porösem anorganischem Material realisiert werden kann.The ignition system disclosed in DE 39 02 617 A1 deals with an improved ignition behavior that can be realized by a disk of porous inorganic material arranged between the ignition source and the ignition charge.
Ein Zünd- bzw. Anzündelement mit einer auf einem Chip angeordneten Zündbrücke ist der DE 196 37 587 A1 entnehmbar. Zur universellen Ersetzbarkeit und Vermeidung eines unkontrollierbaren Abblasens wird vorgeschlagen, dass die Stifte durch eine Glasdurchführung in das Gehäuse des Anzündelementes geführt werden.An ignition or ignition element with an ignition bridge arranged on a chip can be removed from DE 196 37 587 A1. For universal replaceability and avoidance of uncontrollable blow-off, it is proposed that the pins be guided through a glass feedthrough into the housing of the ignition element.
Mit der Problematik einer sicheren Außenkontaktierung eines elektrisch zu zündenden Zündmittels im Fall von Umweltbeanspruchungen beschäftigt sich die DE 33 46 146 A1.With the problem of a secure Außenkontaktierung an electrically ignited ignition means in the case of environmental stresses, DE 33 46 146 A1 is concerned.
Ein kombiniertes Anzündhütchen wird mit der DE 24 43 793 C2 publiziert. Diese weist eine elektrisch initiierbare erste Zündladung und ein zweites Anzündsystem mit einem anstichempfindlichen Zündsatz auf. Durch die Änderung an die Sicherheitsanforderungen insbesondere gegen ein elektrostatisches Aufladungen ist die Verwendung von bisher verwendeten Metallschichtelementen als Zündbrücken (wie z. B. DE 42 22 223 C1 , DD 283 458 A5) in Anzündmittel zu verwerfen.A combined primer is published in DE 24 43 793 C2. This has an electrically initiatable first ignition charge and a second ignition system with a puncture-sensitive ignition charge. As a result of the change to the safety requirements, in particular against electrostatic charging, the use of metal layer elements previously used as ignition bridges (such as, for example, DE 42 22 223 C1, DD 283 458 A5) in igniting agents must be discarded.
Hier stellt sich die Erfindung die Aufgabe, zur Vermeidung von ungewollten Zündungen der Anzündmittel insbesondere durch elektrostatische Aufladungen eine Alternative zur Zündbrücke zu schaffen.Here, the invention has the task of creating an alternative to the ignition bridge to avoid unwanted ignitions of the igniter, in particular by electrostatic charging.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgezeigt.The object is achieved by the features of claim 1. Advantageous embodiments are shown in the subclaims.
Der Erfindung liegt die Idee zugrunde, die (Wieder-)Verwendung von Drähten anzustreben, wobei ein guter Kontakt zwischen den Drähten und der Anzündmischung gewährleistet sein sollte und basiert auf Erfahrungen beim früheren Einsätzen von Einzeldrähten in derartigen Anzündmitteln, die seinerzeit durch die Zündbrücken ersetz worden sind, da sich Einzeldrähte nicht bewährt haben.The invention is based on the idea to strive for the (re) use of wires, whereby a good contact between the wires and the primer mixture should be ensured and based on experience in the earlier use of individual wires in such igniters, which were replaced at the time by the Zündbrücken are because individual wires have not been proven.
Verwendet werden nunmehr Mehrfachdrähte, beispielsweise zwei, wobei beide Drähte einerseits mit einem Kontaktstift des Anzündmittels, andererseits mit einer Masse verbunden und in einem Anzündsatz eingebunden sind. Mit Hilfe der Mehrfachdrähte kann eine Erhöhung des Querschnitts des Brückendrahtes und hierdurch eine Verbesserung des Statikenergieabbaus bewirkt werden (25kV, 50OpF, 500 Ω). Durch die Vergrößerung der Kontaktbereiche zwischen den Drähten und der Anzündmischung wird der Anzündeffekt verbessert. Die Nutzung von Mehrfachdrähten bringt auch den Vorteil mit sich, dass die Funktionssicherheit erhöht wird, da bei Kontaktunterbrechung eines Drahtes die Verbindung über den anderen Draht gewährleistet wird.Now multiple wires, for example two, are used, both wires being connected on the one hand to a contact pin of the igniter, on the other hand to a ground and being incorporated in a primer. With the help of the multiple wires, an increase of the cross-section of the bridge wire and thereby an improvement of the static energy dissipation can be effected (25kV, 50OpF, 500Ω). Increasing the contact areas between the wires and the igniter mixture improves the ignition effect. The use of multiple wires also brings with it the advantage that the reliability is increased, since contact interruption of a wire, the connection is ensured via the other wire.
In einer bevorzugten Ausführung werden zwei Anzündsätze verwendet, wobei der erste Anzündsatz durch die Mehrfachdrähte gezündet und der zweite Anzündsatz durch den ersten Anzündsatz initiiert wird.In a preferred embodiment, two primer sets are used wherein the first primer is ignited by the multiple wires and the second primer is initiated by the first primer.
In Weiterführung der Erfindung ist vorgesehen, Glasdurchführungen in der Masse des Anzündmittels als Isolation zwischen Kontaktstift und Massekontakt einzubinden. Dies bewirkt zudem eine bessere Haftung der ersten Anzündmischung innerhalb des Anzündmittels und dadurch eine verbesserte Funktionssicherheit. Prinzipiell wird die Sicherheit gegen ungewolltes Zünden des Anzündelementes erheblich verbessert. Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.In continuation of the invention, it is provided to incorporate glass bushings in the mass of the igniter as insulation between the contact pin and ground contact. This also causes a better adhesion of the first ignition mixture within the Anzündmittels and thereby improved reliability. In principle, the security against unwanted ignition of the ignition element is significantly improved. Reference to an embodiment with drawing, the invention will be explained in more detail.
Es zeigt die einzige Figur den Aufbau eines Anzündmittels 20, mit wenigstens einem Anzündsatz 5, vorzugsweise mit zwei Anzündätzen 5, 6. Das Anzündmittel 20 besitzt wenigstens eine Hülse 11 , die hier zusätzlich durch eine innere Hülse 4 ergänzt ist. Die äußere Hülse 11 ist an ihrem oberen Ende beispielsweise mittels einer Bördelung 12 verschlossen.The sole figure shows the construction of an ignition means 20, with at least one ignition charge 5, preferably with two ignition charges 5, 6. The ignition means 20 has at least one sleeve 11, which is additionally supplemented here by an inner sleeve 4. The outer sleeve 11 is closed at its upper end, for example by means of a flange 12.
Eine mit einer Aluminiumfolie 3 kaschierte Zelluloidplatte 4 dient als Abdichtung der Explosivstoffe (Anzündsätze 5, 6) und wird als Abschluss auf den oberen, den zweiten Anzündsatz 6 geschoben. Die nach innen gerichtete Wölbung der Zelluloidplatte 2 verstärkt den Befesti- gungs- bzw. Abdichtungseffekt. Durch die Bördelung 12 oder andersartigen Befestigung der äußeren Hülse 11 wird eine generelle Befestigung des Innenteils des Anzündmittels 20 erreicht. Die endgültige Abdichtung kann durch das Auftragen eines Ringfugenlackes 1 geschaffen werden, so dass dieser sich unterhalb der Bördelung 12 befindet und bis in die inneren Hülse 4 hineinragen kann. Alternativ kann die aus Zelluloid bestehende bzw. mit Zelluloid kaschierte Abdeckscheibe 4 auch durch eine Aluminiumscheibe ersetz werden, die Aluminiumfolie 3 entfallen.A laminated with an aluminum foil 3 celluloid plate 4 serves as a seal of the explosives (igniter 5, 6) and is pushed as a conclusion on the upper, the second ignition charge 6. The inward curvature of the celluloid plate 2 enhances the fastening or sealing effect. By the flange 12 or other attachment of the outer sleeve 11, a general attachment of the inner part of the igniter 20 is achieved. The final seal can be created by applying a Ringfugenlackes 1, so that it is below the flange 12 and can protrude into the inner sleeve 4. Alternatively, the existing celluloid or laminated with celluloid cover 4 can also be replaced by an aluminum disc, the aluminum foil 3 omitted.
Unterhalb dieses zweiten Anzündsatzes 6 befindet sich ein erster Anzündsatz 5. Die Einbindung des ersten Anzündsatzes 5 ist vorzugsweise halbkreisförmig oder dergleichen in den zweiten Anzündsatz 6 ragend. Dadurch kann die Fläche für die Übertragung der Anzündung auf die zweite Anzündung 6 positiv erhöht werden. In diesem Anzündsatz 5 eingebunden sind vorzugsweise zwei oder mehrere Brückendrähte 7 (=Mehrfachdrähte), die einerseits mit einem Kontaktstift 10 und andererseits mit einem Massekontakt 9 des Anzündmittels 20 kontaktieren. Die Befestigung der Brückendrähte 7 erfolgt vorzugsweise durch eine Schweißung. Der Durchmesser der Brückendrähte liegt bevorzugt in einer Größenordnung von 250μm.Below this second ignition charge 6 there is a first ignition charge 5. The integration of the first ignition charge 5 is preferably semicircular or the like projecting into the second ignition charge 6. Thereby, the area for the transmission of the ignition to the second ignition 6 can be positively increased. In this ignition charge 5 are preferably two or more bridge wires 7 (= multiple wires), on the one hand contact with a contact pin 10 and on the other hand with a ground contact 9 of the Anzündmittels 20. The attachment of the bridge wires 7 is preferably carried out by a weld. The diameter of the bridgewire is preferably on the order of 250 .mu.m.
Als Isolation zwischen dem Kontaktstift 10 und der Masse 9 dient vorzugsweise eine Glaskomponente, die hier als Glasdurchführung 8 ausgebildet ist. Der Massekontakt 9 hat bevorzugt metallischen Kontakt zur inneren 4 als auch zur äußeren Hülse 11.As insulation between the contact pin 10 and the mass 9 is preferably a glass component, which is designed here as a glass bushing 8. The ground contact 9 preferably has metallic contact with the inner 4 as well as the outer sleeve 11.
Zwischen dem durch die äußere Hülse 11 geführten Kontaktstift 10 und der Hülse 11 selbst ist ein Ringfugenlack 13 zur Abdichtung vorgesehen.Between the guided through the outer sleeve 11 contact pin 10 and the sleeve 11 itself a Ringfugenlack 13 is provided for sealing.
Zur Schaffung des Anzündmittels 20 wird die Anzündmischung bzw. der Anzündsatz 5 dünnflüssig (beispielsweise wie Wasser) auf den Massekontakt 9 mit den Glasdurchführungen 8 aufgetragen. Die in der Anzündmischung 5 enthaltenen schweren Teilchen sinken nach unten in Richtung Massekontakt 9 während der flüssige Anteil nach oben steigt und verdunstet. Hierdurch bildet die Anzündmischung eine feste Außenhaut und es wird ein guter Klebeeffekt zwischen dem Glas der Glasdurchführung 8 und dem Metall des Massekontaktes 9 erreicht. Danach kann die zweite Anzündmischung bzw. der zweite Anzündsatz 6 in die Hülse 11 (Hülse 4) eingebracht werden.To create the igniter 20, the igniter mixture or the primer 5 is liquid (for example, like water) on the ground contact 9 with the glass bushings. 8 applied. The heavy particles contained in the igniter mixture 5 sink down towards the ground contact 9 while the liquid portion rises and evaporates. As a result, the igniter mixture forms a solid outer skin and a good adhesive effect between the glass of the glass feedthrough 8 and the metal of the ground contact 9 is achieved. Thereafter, the second igniter mixture or the second primer 6 in the sleeve 11 (sleeve 4) are introduced.
Das Anzündmittel 20 mit den zwei Anzündsätzen 5, 6 funktioniert wie folgt:The igniter 20 with the two sets of igniters 5, 6 functions as follows:
Die beiden Brückendrähte 7 werden nach Einleitung eines Stromes über den Kontaktstift 10 aufgrund ihres sehr kleinen Durchmessers schlagartig erhitzt. Durch die schlagartige Temperaturerhöhung wird der erste Anzündsatz 5 zur Umsetzung gebracht. Nach Zündung des ersten Anzündsatzes 5 wird die Anzündung auf den zweiten Anzündsatz übertragen.The two bridge wires 7 are heated abruptly after initiation of a current through the contact pin 10 due to their very small diameter. Due to the sudden increase in temperature of the first igniter 5 is brought to implementation. After ignition of the first igniter 5, the ignition is transferred to the second ignition charge.
Es versteht sich, dass die Erfindung im Rahmen des erfinderischen Gedankens Variationen zulässt. So können die Mehrfachdrähte 7 auch bei der Verwendung nur eines elektrischen Anzündsatzes in diese eingebunden werden. Auch ist die Anwendung bzw. Nutzung der Mehrfachdrähte 7 in kombinierten Anzündsystemen möglich.It is understood that the invention allows variations within the scope of the inventive idea. Thus, the multiple wires 7 can be incorporated in the use of only one electric primer in this. Also, the application or use of the multiple wires 7 in combined ignition systems is possible.
