Definitions

  • the invention relates to a safety device for an impact detonator on a projectile, which has a spring-loaded cross slide provided with an ignition capsule, which is held in its safety position by a locking device which can be unlocked by the launch acceleration and which has an ignition pin for piercing the ignition capsule of the cross slide.
  • the object that is to be achieved with the present invention is to create an impact detonator which has two independent safety devices, but which are coupled to one another in such a way that the other safety device can no longer be unlocked if the locking device fails.
  • the object is achieved according to the invention by a manual locking of the firing pin in a position in which the cross slide is held in its safety position and by a locking which prevents the manual unlocking of the firing pin and the release of the cross slide, if the cross slide has already been released by the unlocked locking device has been released.
  • a detonator head 2 is screwed to an igniter housing 1 at the front and an amplifier charge or detonator capsule 3 at the rear.
  • a spring 5 is supported on the one hand on the ignition pin sleeve 6 and on the other hand on a guide sleeve 7 fastened in the ignition head 2.
  • the bearing body 8 inserted into the detonator housing 1 contains an inhibiting mechanism 9 which delays the displacement of a cross slide 10 from its illustrated securing position into the focus position, as a result of which the detonator has a certain security for the front pipe.
  • the detonator housing 1 is provided with a rectangular groove which is guided transversely to the detonator axis and in which the aforementioned prismatic cross slide 10 is mounted.
  • the cross slide 10 contains in one of two bores parallel to the detonator axis the squib 11 to be pierced by the momentary ignition pin 4 and in the other bore the squib 12 to be pierced from the rear (FIG. 2). These bores with the squibs 11 and 12 are staggered in the longitudinal direction of the cross slide 10 and laterally, as can be seen from FIG.
  • the axis of a third, blind bore 13 coincides with the igniter axis in the secured position of the cross slide 10.
  • a spring 14 which is located in a cross bore 15 of the cross slide 10, is supported on the one hand on a guide pin 16 and on the other hand on a shoulder of the cross bore 15 and has the endeavor to move the cross slide 10 into its sharp position.
  • a Locking device 17 prevented, which is slidably mounted in a longitudinal bore 18 of the igniter housing 1 and is pressed forward by a spring 19 into the locking position.
  • This locking device is known per se, therefore reference is made to the Swiss patent no. 594'869, in which this locking device is described in detail.
  • this locking device 17 In order to understand this locking device 17, it is sufficient to point out that, due to the launch acceleration, the locking device 17 moves backwards against the force of the spring 19 in the bore 18 and thereby allows the cross slide 10 to be moved into its sharp position.
  • the cross slide 10 is laterally equipped with a rack 20 which engages in a pinion 21 which is mounted in a plate 22.
  • the pinion 21 is in a manner not shown in engagement with the mentioned escapement 9 whereby, as mentioned, the displacement of the cross slide 10 is delayed in its sharp position and a certain safety precedent is guaranteed.
  • An explosive core 23 extending from the rear edge of the cross slide 10 to the booster charge 3 is inserted in a central longitudinal bore of the ignition body 1 and a device 24 for delayed ignition is contained in a further bore parallel to this. This device 24 is not important in connection with the present invention and is therefore not explained in more detail here.
  • a changeover bolt 25 inserted transversely or perpendicularly to the igniter axis in the ignition head 2 can be manually rotated from the position shown in FIG. 1 to the position shown in FIG.
  • the firing pin 4 has two stops 27 and 28 in its central part 26. If the changeover pin 25 is in the position shown in FIG. 3, the firing pin 4 pushes with its stop 27 under the action. of the spring 5 against the Umstellbolzen 25. The tip 29 of the firing pin 4 projecting into the blind bore 13 of the transverse slide 10 and secures the Q uerschieber 10 against displacement in its armed position.
  • the aforementioned blind bore 13 of the cross slide 10 is covered by a plate 30 which has a bore 31 and a slot 32, as can be seen from FIG.
  • An annular groove 33 is provided behind the tip 29 of the firing pin 4 and fits exactly into the slot 32.
  • the tip 29 of the firing pin 4 has a larger diameter than the slot 32, which prevents displacement of the firing pin 4 when the firing pin 4 with the annular groove 33 is in the slot 32 of the plate 30.
  • the firing pin 4 When the projectile is transported to the weapon using the impact detonator according to the invention, the firing pin 4 is in the position shown in FIG.
  • the tip 29 of the ignition pin 4 protrudes into the blind bore 13 of the cross slide 10 and is not able to pierce the detonator.
  • the changeover pin 25 Before the projectile is inserted into the weapon, the changeover pin 25 is rotated into the position according to FIG. 1 and the spring 5 pushes the ignition pin 4 out of the blind bore 13 in the cross slide, as can be seen from FIG.
  • the locking device 17 is pushed back against the force of the spring 19 by the firing acceleration and the cross slide 10 can shift into its armed position. If the projectile hits the target, the squib 11 is pricked by the firing pin 4.
  • the cross slide 10 can shift to the right so far that the firing pin 4 is held by the slot 32 of the plate 30 of the cross slide 10 because the slot 32 Grips ring groove 33. If the changeover bolt 25 is rotated before the shot is fired, then the spring 5 cannot pull the ignition pin 4 out of the blind bore and the impact detonator remains secured. The projectile will not detonate if it has been shot down.
