Definitions

  • Tinder especially for hand grenades
  • the invention relates to a tinder, in particular for hand grenades, with a tubular tinder housing which has a primer at one (upper) end, including a pyrotechnic delay charge and below the delay charge one by means of propulsive force from the securing into the Detonator which can be moved into focus contains, the delay charge being arranged in an inner support tube, preferably concentric with the tubular scale housing, which carries the detonator at its lower end and is axially displaceably mounted in the tubular scale housing.
  • the displaceable support tube of the delay set with the detonator arranged thereon is held in place by a fusible link, the melting member consisting of a low-melting solder softening due to the heat development when the delay set burns down, as a result of which a melt on the support tube of the delay line ⁇ set attacking spring can relax and the detonator in the focus position (DE-PS 1 578 458).
  • the object of the invention is therefore to avoid the disadvantages of known detonators of the type mentioned at the outset and to create a detonator-safe detonator which can be manufactured without any particular manufacturing difficulties.
  • the outer wall of the carrier tube of the delay charge is sealed in a gas-tight manner with respect to the inner wall of the detonator housing, and also the primer, possibly including the capsule holder, is inserted in the detonator housing in a gas-tight manner, so that in the space above the delay charge If the delay charge burns up, a gas pressure builds up, which causes the delay charge carrier tube, including the detonator, to be displaced in the detonator housing, the detonator coming from the safe position (storage position, transport position) to the arming position (closed ignition chain).
  • the detonator in which it is located at a sufficient distance from the transfer charge, can preferably be secured in that the carrier tube of the delay charge, which also carries the detonator, is directed in the direction of a sufficiently strong compression spring is applied to the upper end of the igniter housing.
  • a sufficiently strong compression spring instead (or additionally) could be large enough Frictional forces, ie a press fit, hold the carrier tube and thus the detonator between the inner carrier tube and the outer igniter housing.
  • a fusible link made of low-melting solder between the inner carrier tube and the outer igniter housing, at least in a supportive manner (for example in addition to the preferred spring action).
  • Such a design would also differ from the prior art, specifically in that, according to the invention, not a spring (as in the prior art) causes the detonator to be moved into the arming position, but rather the gas pressure which arises when the deceleration set burns up.
  • the igniter according to the invention has a structure in which an inner tube (carrier tube) - like the piston of a piston engine in the cylinder - is inserted in an outer tube (igniter housing) in a gas-tight and axially displaceable manner, which contains the deceleration charge and carries the detonator and which is preferably held in place by a spring (or, for example, by a press fit), the inner tube with the detonator being moved into the armed position by the gas pressure of the decelerating charge which is being burned off.
  • Any melting links are dispensable or only provided as an optional addition.
  • Fig. 1 shows a grenade detonator largely in longitudinal section.
  • Fig. 2 also shows a longitudinal section of a variant of a scale house with its contents.
  • the hand grenade detonator shown in Fig. 1 consists - as usual - of an igniter head 1, e.g. made of plastic, on which a racket 2 is rotatably mounted. In the secured state, the racket is tensioned by a spring 3.
  • a securing bracket 4 holds the racket 2 in its cocked position, the securing bracket 4 being secured in turn by a split pin 5.
  • the tubular igniter housing 6 In the central axial bore of the igniter head 1, the tubular igniter housing 6, e.g. made of brass, inserted (screwed in).
  • the scale housing 6 contains a primer 8 upwards in a capsule holder 7. It is important that the capsule holder 7 with the primer 8 closes the interior of the primer housing 6 in a gas-tight manner. The gas tightness must also be maintained if the nipple 9 of the striker 2 strikes the outer brass cap of the primer 8 when the hand grenade is ejected and this brass cap is dented, the pyrotechnical ignition compound located in the interior of the primer 8 being activated and its fire jet enters the interior of the igniter housing 6 through exclusively inward openings of the primer 8 and the capsule holder 7.
  • a coaxial cylindrical support tube 10 for example made of brass.
  • the carrier tube 10 contains the usual pyro-technical sets of a delay charge 11.
  • a detonator housing 12 is molded onto the carrier tube 10
  • Detonator charge 13 contains, for example, lead acid as a primary charge and nitropenta as a secondary charge.
  • the connection between the space for the delay charge 11 and the interior of the detonator housing 12 either remains open or is closed by a fuse plate 11 * which can be blown or melted by the fire jet of the bottom set of the delay charge 11.
  • the carrier tube 10 of the delay charge 11 is arranged with the detonator housing 12 integrally formed thereon in the igniter housing 6, the gap between the outside of the carrier tube 10 and the inside of the initiator housing 6 being sealed gas-tight at least in the region of the upper end of the carrier tube 6, e.g. by means of a sealing ring 14 inserted into an annular groove in the outer wall of the carrier tube 10. If appropriate, a corresponding sealing ring can also be present in the region of the lower end of the carrier tube 10.
  • a helical compression spring 15 is arranged below the carrier tube 10, which is supported on the one hand on a component 16 which is firmly connected to the igniter housing 6 and on the other hand on the carrier tube 10 (or on the detonator housing 12).
  • the upwardly open component 16 which e.g. can consist of aluminum, forms the receiving part for the detonator 12, 13 which has been moved into its focus position and has a cup-shaped depression 17 at the bottom, which is closed at the bottom by a thin membrane-like wall part 18.
  • the igniter housing 6 has lateral openings 20 in the region of the transfer charge 19.
  • the function of the grenade detonator shown in FIG. 1 and described above is as follows: after the safety split pin 5 has been removed and the hand grenade has been thrown off, the safety bracket 4 detaches from the detonator head 1 and the striker 2 hits the outer brass cap of the primer 8 with its nipple 9 The fire jet of the primer first activates the uppermost set of the delay charge 11, which now burns off and thereby generates a high pressure of around 100 bar in the space 21 at the upper end of the carrier tube 10 (high-pressure space).
  • This high pressure causes the carrier tube 10 together with the detonator housing 12 formed thereon to be pushed into the inner receiving space of the component 16 against the action of the spring 15, because low pressure prevails in this area (low pressure space).
  • the pressure in the low-pressure space can increase somewhat due to compression. If this is to be avoided, a small lateral opening 22 in the wall of the scale house can be provided in the area of the low pressure chamber.
  • the detonator housing 12 with the detonator charge 13 arrives in the receiving component 16 above the transfer charge 19, that is, in the arming position.
  • the detonator charge 13 in turn ignites the transfer charge 19 through the thin membrane-like wall part 18 of the receiving component 16, which also detonates the explosive charge of the hand grenade.
  • the fuze must be designed so that, for example, the required drop test from a height of 2.5 m to he * a steel plate from any direction is. After Testing the handling safety and functional safety must be maintained. For this reason, the spring 15 will be made strong enough to prevent movement of the carrier tube 10 of the delay charge.
  • the seal 14 between the carrier tube 10 and the igniter housing 6 could be designed as a “press fit”, which also contributes to obstruction of an unintentional movement of the carrier tube 10.
  • the igniter housing 6 is shown with its content.
  • the detonator head and its components can be designed as in FIG. 1.
  • a carrier tube 10 which contains the delay charge 11 and carries the detonator housing 12 with the detonator charge 13 at its lower end.
  • the detonator housing 6 is sealed gas-tight by the capsule holder 7 and the primer inserted therein.
  • the carrier tube 10 is also sealed in a gas-tight manner with respect to the inner wall of the detonator housing 6, with the aid of a sealing ring 14.
  • the lower end of the detonator housing contains the receiving component 16 for the delay charge 11 under the effect of the combustion gases
  • Detonator housing 12 displaced below with the cup-shaped depression 17, which is closed at the bottom in the manner of a membrane.
  • the wall of the capsule is burst after the transfer charge is detonated, detonating the hand grenade's explosive charge.

Abstract

L'invention concerne une fusée, notamment pour grenades à main, qui comprend un boîtier tubulaire (6) qui contient, à une extrémité (supérieure), une capsule-amorce (8), en-dessous de cette capsule-amorce, une charge pyrotechnique retardatrice (11) et en-dessous de cette pyrotechnique, un détonateur (12, 13) qu'une force propulsive fait passer de la position de sûreté en position active. La charge retardatrice (11) est placée dans un tube-support (10) intérieur, concentrique au boîtier (6) tubulaire de la fusée. Le tube-support (10) soutient le détonateur (12, 13) sur son extrémité inférieure et peut être déplacé dans le sens axial, dans le boîtier (6) tubulaire de la fusée. La paroi extérieure du tube-support (10) de la charge retardatrice (11) est rendue étanche aux gaz vis-à-vis de la paroi intérieure du boîtier (6) de la fusée. La capsule-amorce (8) y compris le porte capsule (7) sont montés de manière étanche aux gaz dans le boîtier de la fusée, de manière à ce que lorsque la charge retardatrice (11) se consume, il se produise une pression gazeuse dans l'espace (21) situé au-dessus de ladite charge retardatrice (11), entraînant un déplacement du tube-support (10) de la charge retardatrice (11), y compris du détonateur (12, 13), dans le boîtier (6) de la fusée, le détonateur passant alors de la position de sûreté en position active.
