Definitions

  • the invention relates to a pyrotechnic detonator for projectiles, missiles, bomblets and mines From the subsequently published EP-A 0 284 923 a bomb detonator is known in which a delay detonator is arranged in a slide next to a detonator.
  • the delay detonator affects the detonator, so that an additional charge of the delay detonator ensures the ignition of the delay detonator on the detonator.
  • the ignition by an additional charge is not always guaranteed, since the spatial distance between the additional charge and the detonator is very large and safe energy transmission is not is always guaranteed.
  • the additional charge is designed as a pyrotechnic booster charge in that it has a high energy content, but which has no detonative character.
  • the gas-generating ignition means is mounted in an axially displaceable piston with a firing needle.
  • the piston moves the ignition needle, which in turn initiates the detonator to ignite an explosive charge.
  • a certain construction volume is required for an axially movable ignition needle with a piston and integrated gas-generating ignition means, which is very difficult to accommodate in a movable slide.
  • the object of the invention is to propose an ignition device in a pyrotechnic detonator with a transversely movable slide, which ensures reliable ignition of a detonator.
  • a slide 3 In a bomblet housing 1 with an ignition needle 2, a slide 3 is locked in the ignition position in a known manner.
  • the slide 3 is located in a guide 4 of a body 5.
  • the slide 3 has a spring 6, a gas expansion chamber 9, a detonator 10 for igniting an explosive charge, not shown, three parallel bores 8, 11, 12 and channel sections 13, 14.
  • the bore 12 is transverse, i.e. tangential to the detonator 10 and has a delay detonator 15, consisting of ignition charge 16, delay charge 18 and overfire charge 19 in a tube 7.
  • the ignition charge 16 is already, as drawn, in reaction.
  • a transmission detonator 20 is fastened in the bore 11 via a disk 22 caulked at 21.
  • a wall 23 separates the transfer detonator 20 from the detonator 10.
  • a dash-dotted line 25 denotes the specially secured starting position of the slide 3.
  • the slide 3 unlocked in a known manner strikes against the housing 1 by the force of the spring 6 and due to the centrifugal forces and is locked in the position shown by a known mechanism.
  • the ignition charge 16 is ignited by the ignition needle 2.
  • the other sets 18 and 19 and the transmission detonator 20 are then fired. This then initiates the detonator 10 through the wall 23.
  • the detonator 10 is reliably fired even under unfavorable conditions. This prevents duds.
  • the channel section 13 also contributes to this with the relaxation space, which discharges the excess pressure which arises when the transmission detonator 20 is ignited into the interior of the housing 1.
  • the detonator 10 therefore remains fully functional in its vertical ignition effect.
  • the overfire charge 19 destroys thin structures and is therefore able to reliably ignite the transfer detonator 20 through the thin wall 30.
  • the existence of the bore 14 is therefore not a requirement. If there is no swirl in the bomblet or on the detonator, the slider 3 is brought into focus solely by the spring 6.
