Definitions

  • the invention relates to an impact detonator, with an ignition capsule which can be pierced from behind by an ignition pin, with locking bodies which are in their locking position on the one hand in a recess in the ignition pin and on the other hand rest on a bolt fastened in the ignition housing and on a displaceable inertia sleeve, to hold the firing pin and with a spring, which is supported with its rear end on the inertial sleeve and tends to hold the inertial sleeve in its rearmost position.
  • a mechanical delay device is provided so that the projectile can penetrate as deep as possible into the target.
  • a device for delayed ignition is provided in addition to a momentary detonator, with an inertial ignition pin which is supported directly by a weak flight safety spring and is held in its initial position during the flight.
  • the delay i. H. Braking of the projectile is initially so small that the inertial firing pin hits the primer at too low a piercing speed and is therefore unable to ignite it properly.
  • the object that is to be achieved with the present invention is now to provide a detonator in which the detonator pin is retained during the penetration process of the projectile into soft earth or snow until the projectile has penetrated on a harder ground.
  • the delay of the floor, i. H. its braking is then so great that when the firing pin is released, it now hits the primer at a sufficiently high piercing speed to ensure proper ignition.
  • the invention also aims to provide a detonator that can be destroyed relatively safely if the detonator has not responded and the projectile has become a dud.
  • the detonator according to the invention differs in that it uses a much stronger flight safety spring. This stronger spring means that if the primer capsule is not pierced correctly, it is more likely that the firing pin will be pushed back and a pricking, e.g. B. is practically avoided by clumsy handling of the dud.
  • the inertial piercing system according to the invention can be used both with an instantaneous capsule as a "double igniter", for example with an additional ignition delay, and with a delayed primer.
  • the igniter is provided with a device which enables the instantaneous -Lock the surcharge system.
  • the impact detonator according to the invention has a housing 10 with a bore 11 and a channel 12.
  • a slide 13 is slidably mounted in the channel 12.
  • this slide 13 contains a primer 14.
  • the primer 14 consists in the usual way of a prick-sensitive primer 15, which is located in a capsule housing 16.
  • This capsule housing 16 has an opening 17 at the bottom through which an ignition pin 18 can pierce the ignition compound 15.
  • the carriage 13 can be moved from a safety position, in which the primer 14 is not in the area of the firing pin 18, to an arming position, in which the primer 14 is located in the area of the firing pin 18.
  • a safety position in which the primer 14 is not in the area of the firing pin 18, to an arming position, in which the primer 14 is located in the area of the firing pin 18.
  • Fig. 1 the safety position and in Fig. 2 and 3 the focus is shown.
  • a sleeve 19 is slidably mounted in the mentioned bore 11 of the housing 10. 1, in the safety position of the slide 13, this sleeve 19 abuts with its front end against this slide 13 and with its rear end against a flange 20 of a bolt 21.
  • This flange 20 abuts a shoulder 22 of the bore 11 and is on the other hand held by a flange 23 in the bore 11.
  • the sleeve 19 is thus secured against any displacement in the safety position of the slide 13. However, as soon as the carriage 13 is in its focused position, the sleeve 19 can be pushed forward against the force of a strong spring 24, as can be seen from FIGS. 2 and 3. In this foremost position of the sleeve 19, a shoulder 25 of the sleeve 19 bears against a ring 26 which is fastened in the housing 10 of the impact detonator. In this sleeve 19, the ignition pin 18 is slidably mounted. At the rear end of the firing pin 18 there is a longitudinal bore 27 and a transverse bore 28.
  • the firing pin 18 has an annular shoulder 31 in the central region, which interacts with a corresponding annular shoulder 32 in the interior of the sleeve 19. As can be seen from FIG. 3, the shoulder 31 of the ignition pin 18 abuts against the shoulder 32 inside the sleeve 19 as soon as the tip of the ignition pin 18 penetrates into the ignition capsule 14.
  • the spring 24 is able, when the delay disappears, to push the sleeve 19 back into its starting position according to FIG. H. 3, the sleeve 19 is pushed back by the amount a. Since the shoulder 31 of the ignition pin 18 rests on the shoulder 32 of the sleeve 19 (FIG. 3), the ignition pin 18 is also pushed back by the amount a. Thus, after the impact delay has disappeared, the firing pin 18 can no longer pierce the squib 14. Since the impact deceleration is relatively large, a correspondingly strong spring 24 can be used. If, therefore, the firing pin 18 is no longer secured against displacement by the locking body 29, as shown in FIG. 1, the firing pin 18 is still secured by the relatively strong spring 24 - after an ignition failure - against undesired puncturing of the primer 14 .

Claims (7)

1. Fusée à percussion comportant une amorce (14) susceptible d'être percutée par l'arrière, par un percuteur (18), et des organes de verrouillage (29) qui en position de verrouillage pénètre d'une part dans une cavité (28), du percuteur (18), et d'autre part s'appuie contre un goujon (21) fixé au boîtier (10) de la fusée et s'appuie contre une douille à inertie (19) coulissante pour maintenir fixe le percuteur (18) et un ressort (24) qui s'appuie d'une part contre la douille à inertie (19) et a tendance à maintenir la douille à inertie (19) dans sa position la plus à l'arrière, caractérisée en ce que le ressort (24) s'appuie par ailleurs sur le boîtier (10) du percuteur et en ce que le déplacement du percuteur (18) vers l'amorce (14) est assuré exclusivement par la force d'inertie s'exerçant sur le percuteur (18).
