Definitions

  • the invention relates to an impact detonator with down tube security.
  • Such an igniter is known from DE-PS 24 26 838.
  • a firing body which is guided in the direction of flight of the projectile and carries a firing cap, is assigned to a firing needle which is fixedly arranged on the detonator.
  • This impact body is locked in the transport and firing position with the aid of locking balls in the detonator housing, which are moved out of their locking position after firing and thus release the impact body. If the projectile hits a target, the impact body slides towards the firing pin because of its inertia, which ignites the primer.
  • a groove is provided in the striking body which is open to the front in the direction of flight and in which at least one locking ball is mounted.
  • a fireproof shoulder is arranged opposite the open end of the groove, which is followed by a receiving space for the ball.
  • the locking ball is pressed onto the bottom of the groove.
  • the launch acceleration ends.
  • the projectile is now braked by air resistance.
  • the ball on which such air resistances do not act, moves due to the effect of the initial acceleration in its career towards the shoulder and then runs into a recording room.
  • the length of time that the ball is for this process can be adjusted by dimensioning the track accordingly.
  • the striking body shoots in the direction of the firing pin, but the locking ball is clamped between the striking body and the shoulder, so that ignition is prevented. This can only take place when the locking ball has finally entered its receiving space.
  • the distance of the front pipe safety that can be achieved with this impact detonator is in the range of a meter or slightly above. This distance can be adjusted by extending the raceway, but this is only possible due to the friction of the ball between the groove and the cylinder housing.
  • the invention has for its object to provide a impact detonator of the type in question, with which the distance for the front pipe security can be extended and reliably set to defined values.
  • the track of the locking ball accordingly has several steps, the ball being reliably deflected at the steps and the distances of the fore-pipe safety can thus be defined.
  • the timing of the movement of the ball from its starting position to the receiving space can be determined very precisely.
  • an impact detonator 2 which has a detonator-proof firing pin 3 and an impact body 4 in which an ignition cap 5 for igniting a smoke-bang charge 6, which is only indicated, is located.
  • the impact body 4 is slidably mounted in the projectile housing surrounding it and is provided with a head 7 which tapers forward in steps. In this head 7, a central bore 8 is provided, into which the firing needle 3 is immersed.
  • the striking body 4 is held in its area adjacent to the projectile housing with two locking balls 9 which engage in the bores 10 penetrating the housing and in depressions 11 on the striking body 4.
  • the projectile 1 is surrounded by a cartridge case 12, wherein between the cartridge case 12 and the locking balls 9 an easily destructible cover 13, for. B. a plastic, paper or metal foil is located.
  • the head 7 of the striking body 4 has adjoining annular grooves 14, 15 and 16, which are separated from one another by ramps 17.
  • the inner wall of the projectile housing is also formed, with an inwardly facing shoulder 18 at the open end of the first annular groove 14, a further shoulder 19 at the open end of the second annular groove 15 and a shoulder 20 at the open end of the annular groove 16 .
  • a receiving space 21 adjoins this shoulder 20.
  • the free space between the head 7 of the impact body and the inner floor wall forms a track 22 for a locking ball 23.
  • the cartridge case 12 remains in the firing device, but without damaging the cover 13.
  • the locking ball 23 is pressed against the bottom of the first groove 14, as shown in FIG. 1.
  • the air drag has a braking effect on the projectile, but not on the blocking ball 23. This travels during the flight of the projectile, and also in steep flight, in its path 22 in the direction of the receiving space 21.
  • the blocking ball 23 reaches the receiving space 21 after a flight distance of the projectile of approximately 15 m. If the projectile subsequently hits a target, the impact body 4 strikes forward upon impact, the two locking balls 9 being pressed out of their recesses 11 and being destroyed by the cover 13 Be hurled free.
  • the now released impact body 4 strikes with the firing cap on the tip of the ignition needle 3, so that the ignition jet can bring the smoke-bang charge 2 to ignition.
  • a locking position of the ball between the second shoulder 19 and the ramp 17 between the first annular grooves 14 and 15 is shown excellent.
  • the location of the ring grooves and shoulders z. B. be chosen so that such a locked position occurs when the projectile hits an obstacle at a distance of about 5 to 8 m before the mouth of the mortar.
  • 23-1 shows a blocking position of the blocking ball between the first shoulder 18 and the ramp of the groove 14, which takes effect at a distance of approximately 1 m from the mouth.
  • the blocking position of the blocking ball takes effect at a distance of approx. 8-12 m before the mouth of the mortar. Ignition is only possible when the locking ball is located in the receiving space 21, i. that is, after a flight distance of more than 12 m, which is marked in FIG. 2 with 23-3.
