Definitions

  • the invention relates to a miniaturized ignition chain.
  • the invention has for its object to provide a miniaturized ignition chain, which can be varied depending on the power requirement at the output of the ignition chain and / or the allowable igniter Einschrauberia in the respective projectile (STANAG).
  • the firing amplifier device of the firing chain has a first firing amplifier and a second firing amplifier which-depending on the power requirement at the output of the firing chain-are modularly combined with one another. At low power requirements, accordingly, only the first firing amplifier of the firing amplifier device is combined with the detonator of the firing chain formed by a miniature detonator.
  • Preferred embodiments or further developments of the modular, miniaturized ignition chain according to the invention are characterized in the subclaims.
  • the modular, miniaturized ignition chain according to the invention has the advantage that it is possible, for example, by removing the second booster stage, ie the second booster, the high-explosive amplifier output for HE ammunition in an ignition amplifier output for igniting transfer charges of a cargo Reduce ammunition. At the same time, an adjustment of the detonator engagement length into the respective projectile takes place.
  • unscrewing or removing the second booster stage for example, to adapt a proximity fuse / multi-function fuse to the use as a time fuse.
  • the modularity is realized in such a way that the incoming booster stages are recorded in recordings that can be connected in a modular, positive or cohesive manner.
  • the recordings can also be identical or identical to the respective booster housing. It may be provided that a booster is screwed or glued into a screw-in. This screw-in can then be screwed onto a thread of a receptacle or a housing of a previous booster stage.
  • Fig. 1 illustrates an embodiment of the modular, miniaturized firing chain with a miniature detonator 10 and an associated detonating chain 12, wherein respect Further details of the miniature detonator 10 and the ignition chain 12 to the following description of FIGS. 2 to 5 Reference is made.
  • Fig. 2 illustrates enlarged a miniature detonator 10, which is provided for over ignition on a firing chain 12.
  • the miniature detonator 10 has a charge 14 small mass of, for example. 10 to 20 mg.
  • the charge 14 is provided for the directed generation of its output from a centric initiation site 16 to a detonator bottom 18.
  • the detonator bottom 18 is formed concaved for forming in a flat disc (flyer) 20 high speed.
  • the Flyer 20 is in Fig. 2 from the miniature detonator 10 axially spaced slightly indicated by thin dashed lines.
  • the charge 14 of the miniature detonator 10 has a primary charge 22 and a secondary charge 24 adjacent thereto.
  • the primary charge 22 is provided in a centering element 26.
  • the secondary charge 24 adjoins the concavely dented detonator bottom 18.
  • the miniature detonator 10 has an electrical bridge element 28.
  • the electric bridge element 28 is provided on an electrically insulating bottom termination element 30 of the miniature detonator 10. Extending out of the electrically insulating bottom termination element 30 are connecting elements 32 which are in contact with the electrical bridge element 28 and are spaced apart from one another.
  • the electrically insulating bottom termination element 30 has a peripheral sleeve 34 which encloses the bottom termination element 30.
  • the centering element 26 is attached to an extension sleeve 36. Between the extension sleeve 36 of the centering element 26 and the peripheral sleeve 34 of the electrically insulating bottom termination element 30 is in the in Fig.2 drawn embodiment of the miniature detonator 10 a compensating sleeve 38 is provided.
  • the concavely dented Detonator founded 18 is termed Subscriber to a detonator shell 40.
  • the detonator shell 40, the extension sleeve 36 of the centering element 26, the compensating sleeve 38 between the extension sleeve 36 and the peripheral sleeve 34 of the bottom end element 30 and the peripheral sleeve 34 are welded tightly to one another at the connection side remote from the concavely dented detonator bottom 18. This tight welding is designated by the reference numeral 42.
  • the miniature detonator 10 forms a first stage of the miniaturized, modular ignition chain, the second stage of which is formed by an insensitive first booster 54 or by a first booster amplifier (see FIGS Figures 3 and 5 ).
  • the insensitive first booster 54 has an input diameter that matches the output diameter of the miniature detonator 10.
  • the first booster 54 has an insensitive explosive charge 56, which is provided in a funnel-shaped widening receiving space 58 of a first booster housing 60.
  • the funnel-shaped enlarged receiving space 58 in the first booster housing 60 is closed on the side facing the miniature detonator with a closing element 62 and on the other side facing away from it by a closing element 64 (see FIGS Figures 3 and 5 ).
  • the insensitive first booster 54 can be combined or combined with a second booster stage 66, which in Fig. 4 from the first booster 54 according to FIG Fig. 3 axially spaced and in Fig. 5 is shown combined with the first booster 54.
  • the two booster stages can be arranged spaced apart depending on the structural conditions in the igniter.
  • the second booster stage 66 has an associated second booster housing 68 which is formed with a likewise funnel-shaped widening receiving space 70.
  • an explosive charge 72 is provided in the receiving space 70.
  • the receiving space 70 of the second booster housing 68 of the second booster stage 68 is at the first booster 54 (see Fig. 3 ) facing side by means of a closing element 74 and on the side facing away from the second side closed by a closing element 76.
  • the end element 64 of the first booster 54 may be concave-dented to form a flyer. Is in Figure 3 illustrated by an arcuate, dashed line 78. Likewise, it is possible for the end element 76 of the second booster stage 66 to be concave-dented to form a flyer. Is in Fig. 4 illustrated by the dashed line 80.
  • the figures illustrate a miniaturized modular firing chain in which the first booster 54, i. H. the first boost amplifier, and the second booster stage 66, d. H. the second firing amplifier, each forming independent components that are arranged adjacent to each other or arranged.
  • the first booster 54 i. H. the first boost amplifier
  • the second booster stage 66 d. H. the second firing amplifier
  • the miniature detonator 10 may, for. B. have a diameter of 2.5 mm and an axial length dimension of 3.5 mm. It is understood that other dimensions are possible.
  • the explosive charge of the miniature detonator is, for example, 10 to 20 mg, without being limited thereto.
