Description

Ein Explosivstoff wird üblicherweise in einem sehr stabilen Behältnis aufbewahrt. Dieses Behältnis umfasst üblicherweise den eigentlichen, entsprechend der Menge des aufzunehmenden Explosivstoffs dimensionierten Behälter sowie ein lösbar am Behälter anbringbares Schließbauteil, über das der Behälter fest verschlossen wird. Der Explosivstoff ist in dem Behältnis verdämmt. Als Behältnis im erfindungsgemäßen Sinn ist dabei jedwedes Behältnis zu verstehen, in dem ein Explosivstoff aufbewahrt wird, also sowohl Verpackungs- und Transportbehältnisse, als auch Munition, also Geschosse, die naturgemäß einen Explosivstoff enthalten.An explosive is usually stored in a very stable container. This container usually includes the actual, according to the amount of the explosive material sized container and a releasably attachable to the container closure member over which the container is firmly closed. The explosive is dammed in the container. As a container in the sense of the invention is to understand any container in which an explosive is stored, so both packaging and transport containers, and ammunition, ie bullets, which naturally contain an explosive.

Um im Brandfall eine ungewollte Detonation des Behältnisses aufgrund einer thermisch induzierten Umsetzung des Explosivstoffs zu vermeiden ist es bekannt, das Behältnis mit einer Ventilations- oder Druckminderungseinrichtung zu versehen, über die der sich im Inneren des Behältnisses aufgrund der Reaktion oder Umsetzung des Explosivstoffs aufbauende Druck über eine Ventilationsöffnung abgebaut werden kann. Im Munitionsbereich spricht man hierbei von einer insensiven Munition, die bei hoher Funktionszuverlässigkeit die Wahrscheinlichkeit einer ungewollten Initiierung des Explosivstoffs durch äußere Einflüsse wie beispielsweise Brand, Beschuss etc. reduziert. Ist im Brandfall die Munition hohen Temperaturen ausgesetzt, beginnt der Sprengstoff durch die erhöhte Temperatur im Inneren des Geschosses auszugasen und zu brennen. Ein solches Geschoss besteht üblicherweise aus einem den Behälter bildenden Geschosskörper sowie einem eine Zündeinrichtung enthaltenden, das Schließbauteil bildenden Zünder, die fest miteinander verschraubt sind. Zur Vermeidung einer thermisch induzierten Detonation ist es bekannt, im Bereich des Geschosskörpers oder einem mechanischen Kopplungsstück zwischen Geschosskörper und Zünder eine oder mehrere Entlüftungsbohrungen vorzusehen, die mittels Kunststoffpfropfen verschlossen sind. Durch den sich aufbauenden Druck werden die Kunststoffpfropfen herausgesprengt, so dass die Entlüftung erfolgen kann. Alternativ kann bei Geschossen ohne ein solches Kopplungsstücks der Zünder unter innerer Druckbelastung vollständig vom Geschosskörper abgetrennt werden, bevor es zu einer Detonation kommt. Jedoch kann über diese Mechanismen oft der gewünschte Insensitivitätsgrad nicht sichergestellt werden.In order to avoid an accidental detonation of the container due to a thermally induced reaction of the explosive in the event of fire, it is known to provide the container with a ventilation or pressure reducing device, via which in the interior of the container due to the reaction or reaction of the explosive pressure building up a ventilation opening can be dismantled. In the ammunition sector this is referred to as an insensitive ammunition which, with high functional reliability, reduces the probability of an unwanted initiation of the explosive by external influences such as fire, shelling, etc. If in the case of fire the ammunition is exposed to high temperatures, the explosive begins to outgas and burn due to the increased temperature inside the projectile. Such a projectile usually consists of a container body forming the projectile and an ignition containing, the closure member forming igniter, which are firmly bolted together. To avoid a thermally induced detonation, it is known to provide one or more vent holes in the region of the projectile body or a mechanical coupling piece between projectile body and igniter, which are closed by means of plastic plugs. By the pressure building up the plastic plugs are blown out so that the venting can take place. Alternatively, in projectiles without such a coupling piece, the igniter can be completely separated from the projectile body under internal pressure load before a detonation occurs. However, these mechanisms often fail to ensure the desired degree of insensitivity.

Der Erfindung liegt damit das Problem zugrunde, ein Behältnis zur Aufbewahrung eines Explosivstoffs anzugeben, das demgegenüber verbessert ist.The invention is therefore based on the problem to provide a container for storing an explosive, which is improved in contrast.

Zur Lösung dieses Problems ist bei einem Behältnis der eingangs genannten Art erfindungsgemäß vorgesehen, dass der Behälter und das Schließbauteil über ein Verbindungsbauteil, das aus zwei mittels eines schmelzbaren Verbindungsstoffes, dessen Schmelztemperatur im Bereich zwischen 80°C bis 170°C liegt, verbundenen Bauteilhälften besteht, miteinander verbunden sind.To solve this problem is provided according to the invention in a container of the type mentioned that the container and the closure member via a connecting member consisting of two by means of a fusible bonding compound whose melting temperature is in the range between 80 ° C to 170 ° C, connected component halves , are interconnected.

Erfindungsgemäß sind der Behälter und das Schließbauteil über ein spezifisch ausgebildetes Verbindungsbauteil gekoppelt, das über eine Schmelzsicherung verfügt. Das Verbindungsbauteil umfasst zwei Bauteile, die mittels eines schmelzbaren Verbindungsstoffes fest miteinander verbunden sind, so dass das Verbindungsbauteil bei üblicher Umgebungstemperatur eine feste, stabile Einheit bildet. Die Schmelztemperatur des Verbindungsstoffes liegt erfindungsgemäß im Bereich zwischen 80°C bis 170°C, bevorzugt zwischen 100°C bis 150°C. Der Schmelztemperaturbereich von 80°C bis 170°C, insbesondere von 100°C bis 150°C ist dabei unter Berücksichtigung von einerseits hohen Umgebungstemperaturen, andererseits von üblichen Umsetzungs- respektive Reaktionstemperaturen verwendeter Explosivstoffe gewählt. Im Einsatz liegt die Umgebungstemperatur respektive die Temperatur, der ein Geschoss ausgesetzt ist, üblicherweise deutlich unterhalb der unteren Schmelztemperatur von 80°C respektive vorzugsweise 100°C. Die Umsetzungs- oder Reaktionstemperatur der Explosivstoffe liegt je nach verwendetem Typ oberhalb von 170°C, also der oberen Schmelztemperaturgrenze, die wie beschrieben bevorzugt 150°C beträgt. Kommt es nun im Falle eines Brandes zu einem Temperaturanstieg am respektive im Behältnis, beispielsweise dem Geschoss, und steigt die Temperatur über die Schmelztemperatur des Verbindungsstoffes, also der Schmelzsicherung, so schmilzt der Verbindungsstoff auf und die vormals feste Verbindung der Verbindungsbauteilhälften ist nicht mehr gegeben. Druckbedingt öffnet sich nun das Behältnis zwangsläufig, indem das Verbindungsbauteil auseinanderfällt. Eines vollständigen Auseinanderfalls bedarf es dabei gar nicht, vielmehr ist es ausreichend, wenn sich druckbedingt die Bauteilhälften nur etwas relativ zueinander bewegen, so dass sich eine geringe Öffnung ergibt, über die ein Druckausgleich möglich ist. Eine Detonation unter Zerbersten des Behältnisses und Splitterbildung mit der Gefahr etwaiger Kollateralschäden ist damit nicht mehr gegeben.According to the invention, the container and the closing component are coupled via a specifically designed connecting component which has a safety fuse. The connecting component comprises two components, which are firmly connected to one another by means of a fusible connecting substance, so that the connecting component forms a solid, stable unit at the usual ambient temperature. The melting point of the compound according to the invention is in the range between 80 ° C to 170 ° C, preferably between 100 ° C to 150 ° C. The melting temperature range of 80 ° C to 170 ° C, in particular from 100 ° C to 150 ° C is selected taking into account on the one hand high ambient temperatures, on the other hand of conventional reaction or reaction temperatures used explosives. In use, the ambient temperature or the temperature, which is exposed to a projectile, usually well below the lower melting temperature of 80 ° C or preferably 100 ° C. Depending on the type used, the reaction or reaction temperature of the explosives is above 170 ° C., ie the upper melting temperature limit which, as described, is preferably 150 ° C. If, in the case of a fire, an increase in temperature occurs in the container, for example the projectile, and the temperature rises above the melting temperature of the connecting substance, ie the fuse, the connecting material melts and the formerly firm connection of the connecting component halves is no longer present. Due to pressure, the container now inevitably opens by the connecting component falling apart. It does not require a complete breakup, it is rather sufficient if, due to pressure, the component halves move only slightly relative to one another, so that a small opening results, via which a pressure compensation is possible. A detonation with bursting of the container and splintering with the risk of collateral damage is thus no longer given.

Der Verbindungsstoff ist bevorzugt ein Lot, also eine Metalllegierung, mit dem die beiden metallenen Bauteilhälften verlötet sind. Ein verwendbares Lot mit einem Schmelzpunkt, der im angegebenen Schmelztemperaturintervall von 80°C bis 170°C, bevorzugt von 100°C bis 150°C liegt, ist beispielsweise Sn42Bi58. Der Schmelzpunkt dieses SnBi-Legierungslotes liegt bei ca. 138°C, also bei einer Temperatur, die weder von der üblichen Umgebungstemperatur erreicht wird, noch in der Nähe der Umsetzungstemperatur eines Explosivstoffes liegt. Anstelle eines Lots wäre auch ein schmelzbarer Kleber denkbar.The connecting material is preferably a solder, ie a metal alloy, with which the two metal component halves are soldered. A usable solder having a melting point in the specified melting temperature interval of 80 ° C to 170 ° C, preferably from 100 ° C to 150 ° C is, for example Sn42Bi58. The melting point of this SnBi alloy solder is about 138 ° C, ie at a temperature that is neither reached by the usual ambient temperature, nor in the vicinity of the reaction temperature of an explosive. Instead of a solder, a fusible adhesive would be conceivable.

Der Behälter und das Schließbauteil selbst sind bevorzugt rotationssymmetrische Teile, wobei das Verbindungsbauteil in diesem Fall als Verbindungsring ausgeführt ist. Die Ausbildung der entsprechenden Elemente als rotationssymmetrische Teile macht deren Herstellung und Montage besonders einfach.The container and the closure member itself are preferably rotationally symmetrical parts, wherein the connecting member is designed in this case as a connecting ring. The formation of the corresponding elements as rotationally symmetrical parts makes their manufacture and assembly particularly simple.

Ein solches rotationssymmetrisches Behältnis ist besonders bevorzugt als Geschoss ausgeführt, umfassend einen den Behälter bildenden Geschosskörper sowie einen eine Zündeinrichtung enthaltenden, das Schließbauteil bildenden Zünder, die über den Verbindungsring miteinander verbunden sind. Dabei kann das Geschoss beliebiger Art sein, d. h., es kann einen Kopfzünder oder einen Bodenzünder etc. enthalten.Such a rotationally symmetrical container is particularly preferably embodied as a projectile, comprising a projectile body forming the container and an igniter containing the closing component forming igniter, which are connected to one another via the connecting ring. In this case, the bullet can be of any kind, d. h., it may contain a head igniter or a bottom detonator, etc.

Der Verbindungsring besteht bevorzugt aus zwei die Bauteilhälften bildenden Ringhälften, die axial ineinandergreifen und über den Verbindungsstoff miteinander verbunden sind. D. h., dass die eine Ringhälfte die andere Ringhälfte außenseitig radial übergreift. Die jeweiligen Durchmesser sind selbstverständlich entsprechend aufeinander abgestimmt, so dass sich ein weitgehender spielfreier Übergriff ergibt. Dabei ist zweckmäßigerweise am Innenumfang der einen Ringhälfte und am Außenumfang der anderen Ringhälfte jeweils eine Anschlagkante vorgesehen, wobei die Anschlagkanten beim Ineinanderschieben aneinander anschlagen und die Einschiebebewegung begrenzen. Hierüber ist zum einen die Montage der Ringhälften einfach, zum anderen sind die beiden Ringhälften bei Kantenanschlag aneinander festgelegt, so dass der Verbindungsstoff, also bevorzugt das Lot, ohne Weiteres zur Verbindung der Ringhälften aufgebracht werden kann. Bevorzugt sind dabei die Ringhälften gleich lang, so dass die eine Ringhälfte vollständig in der anderen aufgenommen ist und sich ein insgesamt kompakter, doppelwandiger Verbindungsring ergibt.The connecting ring preferably consists of two halves of the ring forming the component halves, which engage axially and are connected to one another via the connecting material. D. h., That the one half of the ring radially overlaps the other half of the ring outside. The respective diameters are, of course, matched to one another, so that there is a largely play-free overgrip. In this case, a stop edge is expediently provided on the inner circumference of the one half of the ring and on the outer circumference of the other half of the ring, wherein the stop edges abut each other when telescoping and limit the Einschiebebewegung. On the one hand, the assembly of the ring halves is simple on the one hand, on the other hand, the two ring halves are fixed to each other at edge stop, so that the connecting material, so preferably the solder, can be readily applied for connecting the ring halves. Preference is given to the Ring halves of the same length, so that the one half of the ring is completely absorbed in the other and results in an overall compact, double-walled connection ring.

Zur Verbindung der Ringhälften respektive zur Einbringung des Verbindungsstoffes kann gemäß einer vorteilhaften Weiterbildung der Erfindung stirnseitig am Verbindungsring eine von beiden Ringhälften begrenzende Nut vorgesehen sein, in der der Verbindungsstoff aufgenommen ist. Über diese Nut, die bevorzugt V-förmig im Querschnitt ist, wird ein hinreichend großes Volumen geschaffen, in das der Verbindungsstoff, also bevorzugt das Lot, eingebracht werden kann. Da die Nut von beiden Ringhälften begrenzt ist, benetzt der Verbindungsstoff beide Ringhälftenflächen, so dass diese fixiert sind. Hierüber ist auch eine hinreichend große Benetzungsfläche realisiert, insbesondere wenn die Nut V-förmig ausgeführt ist.To connect the ring halves respectively for introducing the compound can be provided according to an advantageous embodiment of the invention, the front side of the connecting ring a limiting of both ring halves groove in which the compound is added. About this groove, which is preferably V-shaped in cross section, a sufficiently large volume is created, in which the bonding material, so preferably the solder, can be introduced. Since the groove of both halves of the ring is limited, the compound wets both ring halves surfaces so that they are fixed. This also a sufficiently large wetting surface is realized, especially if the groove is V-shaped.

Zur einfachen Verbindung des Verbindungsringes mit dem Behälter und dem Schließbauteil sind an den beiden Ringhälften bevorzugt endseitige Gewindeabschnitte vorgesehen, die in entsprechende Gewindeabschnitte am Behälter und am Schließbauteil eingeschraubt sind. Es ist also eine einfache Schraubverbindung realisiert. Dabei kommt es nicht darauf an, ob der Verbindungsring zunächst am Behälter, also beispielsweise dem Geschosskörper angeschraubt wird, und sodann das Schließbauteil, also beispielsweise der Zünder in den Verbindungsring eingeschraubt wird, oder umgekehrt.For easy connection of the connecting ring with the container and the closing component, preferably end-side threaded sections are provided on the two ring halves, which are screwed into corresponding threaded sections on the container and on the closing component. So it is a simple screw realized. It does not matter whether the connecting ring is first screwed to the container, so for example the projectile body, and then the closure member, so for example the igniter is screwed into the connecting ring, or vice versa.

Am offenen Ende des Geschosskörpers 3 ist ein Innengewindeabschnitt 5 vorgesehen, in den ein Verbindungsring 6, der ein Außengewinde 7 aufweist, eingeschraubt ist. Der Verbindungsring 6 weist des Weiteren ein am anderen Ringende vorgesehenes Innengewinde 8 auf. In dieses Innengewinde 8 wird ein Zünder 9, der in einer Kammer 10 üblicherweise eine nicht näher dargestellte Zündeinrichtung aufweist, mit einem Außengewinde 11 eingeschraubt. Die Gewindeabschnitte 7 und 8 des Verbindungsrings 6 sind in den Fig. 2 und 3 zu sehen, in denen der Verbindungsring 6 detaillierter dargestellt ist. Über die nicht näher gezeigte Zündeinrichtung wird der Explosivstoff 4 bei Bedarf gezündet. Fig. 1 shows in the form of a schematic diagram of an inventive container 1 in the form of a projectile 2, comprising a designed as a hollow cylindrical, rotationally symmetric component projectile body 3, in which the explosive 4 is added. At the open end of the projectile body 3, a female threaded portion 5 is provided, in which a connecting ring 6, which has an external thread 7, is screwed. The connecting ring 6 furthermore has an internal thread 8 provided on the other ring end. In this internal thread 8, an igniter 9, which usually has a non-illustrated ignition device in a chamber 10, with an external thread 11 is screwed. The threaded portions 7 and 8 of the connecting ring 6 are in the FIGS. 2 and 3 to see in which the connecting ring 6 is shown in more detail. About the igniter not shown in detail the explosive 4 is ignited if necessary.

Wesentliches erfindungsgemäßes Element ist der Verbindungsring 6, der in den Fig. 2 und 3 im Detail dargestellt ist. Der Verbindungsring 6 besteht aus zwei Ringhälften 12 und 13, die ineinandergreifen, wobei die Ringhälfte 12 das außenliegende Teil und die Ringhälfte 13 das innenliegende Teil ist. An beiden Ringhälften 12, 13 sind jeweils Anschlagkanten 14, 15 vorgesehen, die über entsprechende Stufen gebildet sind. Über diese Anschlagkanten 14, 15 wird die Einschiebebewegung der Ringhälfte 13 in die Ringhälfte 12 begrenzt, so dass eine definierte Positionierung beider Ringhälften zueinander in einer ausgezeichneten Endstellung gegeben ist. Ersichtlich sind die beiden Ringhälften 12, 13 axial gesehen gleich lang, so dass sich quasi ein zweiwandiger Verbindungsring 6 ergibt. Die jeweiligen Innen- und Außendurchmesser sind entsprechend aufeinander abgestimmt, so dass sich eine weitestgehend spielfreie oder nur minimales Spiel aufweisende Steckverbindung ergibt.Essential element of the invention is the connecting ring 6, in the FIGS. 2 and 3 is shown in detail. The connecting ring 6 consists of two ring halves 12 and 13, which engage with each other, wherein the ring half 12, the outer part and the ring half 13 is the inner part. At both ring halves 12, 13 each stop edges 14, 15 are provided, which are formed via corresponding stages. About this stop edges 14, 15, the insertion movement of the ring half 13 is limited in the ring half 12, so that a defined positioning of both ring halves is given to each other in an excellent end position. As can be seen, the two ring halves 12, 13 are the same length when viewed axially, so that virtually a two-walled connecting ring 6 results. The respective inner and outer diameters are coordinated accordingly, so that there is a largely play-free or minimal play having plug connection.

Vorgesehen ist des Weiteren eine am Verbindungsring 6 ausgeführte stirnseitig ausgebildete Nut 16, die, siehe Fig. 3, im Querschnitt V-förmig ist. Die Nut 16 wird von beiden Ringhälften 12, 13 über entsprechende Nutflächen 17, 18 begrenzt. In der Nut 16 ist ein schmelzbarer Verbindungsstoff 19, hier in Form eines Lotes 20 aufgenommen, d. h., dass die Nut 16 vollständig mit dem Lot 20 gefüllt ist. Das Lot ist bevorzugt eine SnBi-Legierung, vorzugsweise Sn42Bi58. Es wird aufgeschmolzen in die Nut 16 eingebracht, so dass es die Nutflächen 17, 18 der bei Bedarf hierbei ebenfalls beheizten metallenen Ringhälften 12, 13 vollständig benetzt. Nach dem Aushärten des Lotes 20 sind die Ringhälften 12, 13 fest miteinander verbunden.Further provided is a running on the connecting ring 6 front-side groove 16, see Fig. 3 , in cross-section is V-shaped. The groove 16 is bounded by two ring halves 12, 13 via corresponding groove surfaces 17, 18. In the groove 16 is a fusible link 19, here taken in the form of a solder 20, that is, that the groove 16 is completely filled with the solder 20. The solder is preferably a SnBi alloy, preferably Sn42Bi58. It is melted introduced into the groove 16 so that it the groove surfaces 17, 18 of this case if necessary also heated metal ring halves 12, 13 completely wetted. After curing of the solder 20, the ring halves 12, 13 are firmly connected.

Das Lot 20 weist einen Schmelzpunkt auf, der bevorzugt im Bereich zwischen 100°C bis 150°C liegt. Ist also eine Temperatur im Bereich des Lotes gegeben, die in diesem Temperaturbereich liegt, so verflüssigt sich das Lot und die stoffschlüssige Verbindung der Ringhälften 12, 13 wird gelöst. Der Schmelzpunkt des Lotes Sn42Bi58 liegt bei ca. 138°C. Er liegt damit innerhalb des angegebenen Temperaturintervalls und ist einerseits deutlich höher als maximal mögliche Umgebungstemperaturen, denen ein Geschoss im Einsatz ausgesetzt ist. Er ist aber auch deutlich niedriger als die Reaktions- oder Umsetzungstemperatur des verwendeten Explosivstoffes 4.The solder 20 has a melting point, which is preferably in the range between 100 ° C to 150 ° C. So if a temperature in the range of the solder is given, which is in this temperature range, the solder liquefies and the cohesive connection of the ring halves 12, 13 is released. The melting point of the solder Sn42Bi58 is approx. 138 ° C. It is thus within the specified temperature interval and on the one hand significantly higher than the maximum possible ambient temperatures to which a projectile is exposed in use. But it is also significantly lower than the reaction or reaction temperature of the explosive 4 used.

Kommt es nun zu einem Brand, dem das Geschoss 2 ausgesetzt ist, so erwärmt es sich. Dabei steigt die Temperatur auch im Bereich des Verbindungsringes 6 und folglich auch des Lots 20. Wird dessen Schmelztemperatur erreicht, so schmilzt es auf und die feste Verbindung der Ringhälften 12, 13 wird gelöst. Der Zünder 9 liegt damit lose auf dem Geschosskörper 3 auf. Hierdurch ist der Explosivstoff 4 nicht mehr verdämmt. Kommt es nun temperaturbedingt zu einem Ausgasen des Explosivstoffs 4, so kann bereits bei minimalem Innendruck der Zünder 9 etwas aus dem Geschosskörper 3 bewegt werden, d. h., dass sich die innere Ringhälfte 13 etwas aus der äußeren Ringhälfte 12 bewegt, so dass sich ein schmaler Entlüftungsspalt ergibt, durch den der geringe Überdruck abgebaut wird. Bei weitergehender Erwärmung des Explosivstoffs kann dieser ohne Weiteres aus dem Geschosskörper 3 herausfließen und abbrennen, eine Detonation unter Zerbersten des Geschosses ist damit ausgeschlossen.If it comes to a fire, to which the bullet 2 is exposed, it heats up. The temperature also rises in the region of the connecting ring 6 and consequently also of the solder 20. If its melting temperature is reached, it melts and the firm connection of the ring halves 12, 13 is released. The igniter 9 is thus loose on the projectile body 3. As a result, the explosive 4 is no longer dammed. If, due to the temperature, an outgassing of the explosive 4 occurs, then the igniter 9 can be moved slightly out of the projectile body 3 even at a minimal internal pressure, ie. h., That the inner ring half 13 moves slightly from the outer ring half 12, so that there is a narrow vent gap through which the low pressure is reduced. Upon further heating of the explosive, it can readily flow out of the projectile body 3 and burn off, a detonation under rupture of the projectile is thus excluded.

Fig. 4 zeigt exemplarisch das Geschoss aus Fig. 1 nach Aufschmelzen des Lotes 20, wobei hier aus Gründen der Übersichtlichkeit der Zünder 9 relativ weit aus dem Geschosskörper 3 herausbewegt ist. Ersichtlich ist jedoch in jedem Fall, dass die beiden Ringhälften 12, 13 nicht mehr stoffschlüssig miteinander verbunden sind, sondern aufgrund des Aufschmelzens des Lotes 20 gelöst sind, so dass der Zünder 9 samt daran verschraubter Ringhälfte 13 vom Geschosskörper 3 samt daran verschraubter Ringhälfte 12 wegbewegt wurde. Fig. 4 shows an example of the projectile Fig. 1 after melting of the solder 20, wherein for reasons of clarity of the igniter 9 is relatively far out of the projectile body 3 moved out. It is apparent, however, in any case, that the two ring halves 12, 13 are no longer cohesively connected to each other, but are solved due to the melting of the solder 20, so that the igniter 9 together with screwed ring half 13 away from the projectile body 3 together with screwed ring half 12 has been.

Durch Integration des erfindungsgemäßen Verbindungsbauteils, hier in Form des Verbindungsringes 6, ist mit besonderem Vorteil ausgeschlossen, dass es im Brandfall zu einer ungewollten und unkontrollierten Detonation des Explosivstoffes 4 kommt.By integration of the connecting component according to the invention, here in the form of the connecting ring 6, is excluded with particular advantage that it comes in case of fire to an unwanted and uncontrolled detonation of the explosive 4.

Eine solche Detonation kann zu beachtlichen Kollateralschäden führen, denn häufig geht damit ein Zerbersten des Geschosskörpers 3, an dessen Außenseite üblicherweise ein Splittermantel 21 vorgesehen ist, einher, was zu großen Kollateralschäden führen kann.Such a detonation can lead to considerable collateral damage, because often a bursting of the projectile body 3, on the outside of which usually a splitter casing 21 is provided, is accompanied, which can lead to large collateral damage.
