Abstract

EFI-Zündvorrichtung mit einem Zündübertrager (S), der nach Initiierung einer Zündbrücke über eine fliegende Platte (Flyer) ausgelöst werden kann, wobei die Zündplatine (PZ) mit der Zündbrücke mittels eines frei beweglichen, biegefesten, flächigen Bauteils (FB) und eines elastisch vorspannbaren Dämpfungselementes (DK) gegen Hochschockbelastungen geschützt ist.EFI ignition device with an ignition transformer (S), which can be triggered after initiation of a firing bridge on a flying plate (flyer), the ignition board (PZ) with the ignition bridge by means of a freely movable, bending-resistant, flat component (FB) and an elastic prestressed damping element (DK) is protected against high shock loads.

Description

Die Erfindung betrifft eine schockresistente EFI-Zündvorrichtung, umfassend eine Platine mit wenigstens einer leitfähigen Schicht, eine Zünderplatine mit einer elektrischen Zündbrücke, eine an der Zündbrücke anliegende Folie, aus der ein Flyer ausstanzbar ist, ein an der Folie anliegendes Barrel mit einer der Größe des Flyers entsprechenden Öffnung, einem Sprengstoff enthaltenden Zündübertrager, der unmittelbar am Barrel anliegt, und einem die Zündvorrichtung zumindest teilweise umgebenden Gehäuse.The invention relates to a shock-resistant EFI ignition device, comprising a circuit board with at least one conductive layer, a detonator plate with an electric ignition bridge, a voltage applied to the ignition bridge foil from which a flyer is punched out, a voltage applied to the film barrel with a size of Flyers corresponding opening, an explosive-containing ignition transformer which rests directly on the barrel, and a housing surrounding the ignition at least partially.

Derartige EFI-Zündmodule (EFI = Exploding Foil Initiator) werden verbreitet in Waffensystemen eingesetzt. In der DE 10 2011 108 000 A1 ist ein kompaktes EFI-Zündmodul beschrieben. Es umfasst ein zentrales EFI-Zündbauteil mit einer Platine, auf der ein leitfähiges Element als Zündbrücke ausgeführt ist. Sobald der Zündbrücke ausreichend Energie zugeführt wird verdampft das leitfähige Element schlagartig. Dadurch wird aus der anliegende Folie ein Teil, nämlich der sogenannte Flyer, herausgesprengt, dessen Größe durch die Öffnung im genau darunter befindlichen Barrel bestimmt ist. Der Flyer wird somit in Richtung des Zündübertragers extrem beschleunigt. Beim Auftreffen des Flyers wird der Sprengstoff des Zündübertragers durch die Stoßwelle zur Explosion gebracht.Such EFI (Exploding Foil Initiator) ignition modules are widely used in weapon systems. In the DE 10 2011 108 000 A1 a compact EFI ignition module is described. It comprises a central EFI ignition component with a printed circuit board, on which a conductive element is designed as ignition bridge. As soon as the ignition bridge is supplied with sufficient energy, the conductive element evaporates abruptly. As a result, a part, namely the so-called flyer, is blown out of the adjacent film, the size of which is determined by the opening in the barrel located just below. The flyer is thus extremely accelerated in the direction of the Zündübertragers. Upon impact of the flyer, the explosive of the Zündübertragers is brought by the shock wave to the explosion.

In diesem Dokument wird zwar der Aufbau einer kompakten EFI-Zündvorrichtung beschrieben. Es wird jedoch kein Hinweis darauf gegeben, welche Maßnahmen zu treffen sind, wenn die Zündvorrichtung in einem Gefechtskopf, insbesondere einem Penetrator, eingesetzt wird. Bei solchen Anwendungsfällen treten extreme Stoßbelastungen auf, die zum Ausfall einer EFI-Zündvorrichtung bekannter Bauart führen können.Although this document describes the construction of a compact EFI ignition device. However, no indication is given as to what measures should be taken when the ignition device is used in a warhead, in particular a penetrator. In such applications, extreme shock loads occur, which can lead to failure of an EFI ignition device of known type.

Es ist deshalb Aufgabe der Erfindung eine bekannte EFI-Zündvorrichtung dahin gehend zu verbessern, dass die Zündvorrichtung nicht nur hohe Schockbelastungen funktionsfähig übersteht, sondern auch noch bezüglich der fallweise zu erwartenden Intensität der Belastung anpassbar ist.It is therefore an object of the invention to improve a known EFI ignition device in such a way that the ignition device not only survives high shock loads, but also with respect to the expected case intensity intensity is adaptable.

Zur Lösung der Aufgabe wird gemäß der Erfindung vorgeschlagen, dass an der der Folie gegenüber liegenden Seite der Platine ein frei bewegliches, biegefestes flächiges Bauteil anliegt, dessen Querabmessungen geringfügig kleiner als die lichte Weite des Gehäuses in diesem Bereich sind, und dass auf der anderen Seite des flächigen Bauteils wenigstens ein elastisches vorspannbares Dämpfungselement anliegt, und dass die andere Seite des Dämpfungselements an einem mit dem Gehäuse in Wirkverbindung stehenden Gehäusebauteil anliegt, und dass schließlich das Gehäusebauteil gegenüber dem Gehäuse zur Erzeugung der Vorspannung verstellbar ist.To achieve the object, it is proposed according to the invention that on the film side opposite the board a freely movable, bending-resistant planar component is applied, whose transverse dimensions are slightly smaller than the inside diameter of the housing in this area, and that on the other side at least one elastic prestressable damping element abuts the planar component, and that the other side of the damping element rests against a housing component operatively connected to the housing, and finally that the housing component is adjustable relative to the housing for generating the prestress.

Das Dämpfungselement kann beispielsweise aus einem reversibel verformbaren elastischen Kunststoff bestehen. Alternativ dazu kann wenigstens ein Federelement Verwendung finden, dessen Kennlinie für den jeweiligen Anwendungsfall ausgewählt wird. Das Gehäusebauteil, an dem das Dämpfungselement auf der dem flächigen Bauteil abgewandten Seite anliegt, dient als Gegenlager wenn das Dämpfungselement für den jeweiligen Anwendungsfall vorgespannt wird. Das Gehäusebauteil ist in zweckmäßiger Weise als plattenförmiger Deckel ausgeführt, dessen Wandstärke so ausgelegt wird, dass die gewählte Vorspannung des Dämpfungselements problemlos aufgenommen und an das Gehäuse weitergegeben wird. In idealer Weise sind an der Innenseite des Gehäuses und am Außenrand des Deckels korrespondierende Abschnitte eines Feingewindes vorgesehen. Mit Hilfe dieses Feingewindes kann das Gehäusebauteil in das Gehäuse eingedreht werden, wodurch das Dämpfungselement immer stärker komprimiert wird. Auf diese Weise kann die für den Anwendungsfall ermittelte notwendige Dämpfung auf einfache Weise eingestellt werden.The damping element may for example consist of a reversibly deformable elastic plastic. Alternatively, at least one spring element can be used whose characteristic curve is selected for the particular application. The housing component, on which the damping element rests on the side facing away from the sheet-like component side, serves as an abutment when the damping element is biased for the particular application. The housing component is expediently designed as a plate-shaped lid whose wall thickness is designed so that the selected bias of the damping element is easily absorbed and passed on to the housing. Ideally, corresponding sections of a fine thread are provided on the inside of the housing and on the outer edge of the lid. With the help of this fine thread, the housing component can be screwed into the housing, whereby the damping element is compressed more and more. In this way, the necessary damping determined for the application can be set in a simple manner.

Ausführungsbeispiele der Erfindung sind in den Figuren der Zeichnung dargestellt. Es zeigen:

Fig. 2:
eine EFI-Zündvorrichtung mit dämpfenden Federelementen.
Embodiments of the invention are illustrated in the figures of the drawing. Show it:
Fig. 1:
a shock-resistant EFI ignition device with adjustable damping element,
Fig. 2:
an EFI ignition device with damping spring elements.

Die Figur 1 zeigt eine von verschiedenen Möglichkeiten, wie eine bekannte EFI-Zündvorrichtung mit einer Dämpfung für große Beschleunigungen ausgestattet werden kann. In einem massiven Gehäuse G ist mittig ein Sprengstoff enthaltender Zündübertrager Z angeordnet, der im Fall seiner Initiierung (in der Zeichnung nach unten) eine größere Ladung zünden kann. Auf seiner Oberseite ist ein scheibenförmiges Barrel B mit einer zentralen Bohrung angeordnet. Unmittelbar darüber liegt eine dünne Kunststofffolie F, aus der der Flyer ausgestanzt wird, der mittels extremer Beschleunigung durch die Bohrung im Barrel B fliegt und damit den Zündübertrager S auslöst.The FIG. 1 shows one of several ways in which a known EFI ignition device can be equipped with high acceleration damping. In a solid housing G, an explosive-containing ignition transformer Z is centrally located, which in the case of its initiation (in the drawing down) can ignite a larger charge. On its upper side a disc-shaped barrel B is arranged with a central bore. Immediately above is a thin plastic film F, from which the flyer is punched, which flies by means of extreme acceleration through the hole in barrel B and thus triggers the ignition transformer S.

Unmittelbar auf der Folie F, die üblicherweise aus einem Kunststoff wie Polyimid besteht, liegt die Zünderplatine PZ auf, die auf der Unterseite eine elektrische Zündbrücke trägt. Die Zündbrücke erhält über Leitungen E von der Platine P der Zündschaltung den für die Initiierung notwendigen Strom. Die Zünderplatine PZ ist im Ausführungsbeispiel als Multilayer aus Leiterplattenmaterial gefertigt. Üblicherweise ist die Zünderplatine PZ mit dem Barrel B verklebt. Um ein spaltfreies Aufliegen des Barrels B auf dem Zündübertrager S zu gewährleisten, wird die Vorspannung des Dämpfungselements DK, DF genutzt.Immediately on the film F, which usually consists of a plastic such as polyimide, is the igniter board PZ, which carries an electric ignition bridge on the underside. The ignition bridge receives via lines E from the board P of the ignition circuit necessary for the initiation of electricity. The detonator PZ is made in the embodiment as a multilayer of printed circuit board material. Usually, the igniter plate PZ is glued to the barrel B. In order to ensure a gap-free resting of the barrel B on the Zündübertrager S, the bias of the damping element DK, DF is used.

Um Beschädigungen an der Zünderplatine PZ durch die Dämpfungselemente DK, DF zu vermeiden, wird ein flächiges Bauteil FB, beispielsweise eine Metallscheibe zwischen das Dämpfungselement DK, DF gelegt. Damit wird auch der Flächendruck auf die Zünderplatine PZ gleichmäßig verteilt. Um eine Beweglichkeit des flächigen Bauteils FB zu gewährleisten ist dieses etwas kleiner dimensioniert als die lichte Weite des Gehäuses G in diesem Bereich.In order to avoid damage to the igniter plate PZ by the damping elements DK, DF, a flat component FB, for example, a metal disc between the damping element DK, DF is placed. Thus, the surface pressure on the detonator PZ is evenly distributed. In order to ensure mobility of the planar component FB this is slightly smaller dimensions than the inside diameter of the housing G in this area.

Das Dämpfungselement DK ist im Ausführungsbeispiel als Kunststoffplatte, beispielsweise aus Silikon, ausgeführt. Je nach bei der Anwendung zu erwartender Schockbelastung können unterschiedliche Materialien eingesetzt werden. Weiterhin kann die Wahl der Dicke des Dämpfungselements DK als Stellgröße eingesetzt werden.The damping element DK is executed in the embodiment as a plastic plate, for example made of silicone. Depending on the shock load to be expected during the application, different materials can be used. Furthermore, the choice of the thickness of the damping element DK can be used as a control variable.

Der Druck, der auf das Dämpfungselement DK (in der Zeichnung von oben her) ausgeübt wird, ist das nächste Mittel zur Festlegung der Dämpfung. Im Ausführungsbeispiel wird der Druck mit Hilfe des Gehäusebauteils GB auf das Dämpfungselement DK ausgeübt. Das Gehäusebauteil GB ist dabei als stabiler Deckel ausgeführt, der mit seiner Innenfläche auf dem Dämpfungselement DK flächig aufliegt. Außerdem weist der Deckel radial ein Außen-Feingewinde FG auf, das mit einem entsprechenden Innengewindeabschnitt auf der Innenseite des Gehäuses G korrespondiert. Der Deckel wird mit einem hier nicht dargestellten Schlüssel nach Bedarf gedreht, wobei der Schlüssel in auf der Außenseite des Deckels eingelassene Ausnehmungen V eingreift.The pressure exerted on the damping element DK (in the drawing from above) is the next means for determining the damping. In the exemplary embodiment, the pressure is exerted on the damping element DK with the aid of the housing component GB. The housing component GB is designed as a stable lid, which rests flat with its inner surface on the damping element DK. In addition, the cover has a radially outer fine thread FG, which corresponds to a corresponding internal threaded portion on the inside of the housing G. The lid is rotated with a key, not shown here as needed, the key engages in recessed on the outside of the lid recesses V.

Die Figur 2 zeigt eine weitere Lösungsmöglichkeit für das Dämpfungselement DF. Hier werden beispielhaft für weitere Ausführungsformen Schraubenfedern DF vorgespannt als Dämpfungselemente eingesetzt. Es sind weitere Bauformen wie z. B. Tellerfedern bekannt, die hier alternativ verwendet werden können. Im Übrigen ist die Zündvorrichtung baugleich mit der in Figur 1 dargestellten Zündvorrichtung.The FIG. 2 shows a further possible solution for the damping element DF. Here are used as examples of other embodiments coil springs DF biased used as damping elements. There are other designs such. B. disc springs known that can be used here alternatively. Incidentally, the ignition device is identical to the in FIG. 1 illustrated ignition device.
