Definitions

  • the invention relates to a detonator for low-swirl and for swirl projectiles with a recoil pin system consisting of two recoil pins coupled to one another via a ball, with a rotor or slide for receiving a detonator and with an inhibitor controlling the focus of the rotor or slide in a housing of the detonator.
  • An igniter of the type mentioned is known from DE-PS 31 07 110.
  • This is a safety device for a detonator of swirl projectiles with a recoil pin system, which is arranged within the rotor. Due to the launch acceleration of a projectile, a recoil bolt is moved backwards against the pressure of a spring. Due to the translational acceleration, the ball mounted on a cone of the second recoil bolt is pushed against an opposite cone of the first recoil bolt. The spring on the first recoil pin, via its cone and the ball used, locks the recoil pin system in the unlocked position, as a result of which the rotor is finally unlocked by the second recoil pin.
  • this object is achieved in that a spring is provided, the first leg of which rests securely on the lower end of a cone of an axially movable recoil bolt and the second leg of which engages with its end on a pin or in a recess in the lateral surface of the slide or rotor.
  • the spring is a leg spring bent around the bolt in a U-shape.
  • the second leg of this spring lies against a shorter wall of the recess lying on the radius of the rotor in the rotational drive direction.
  • a spring tensioning system is provided for the rotor arming on a detonator when the projectile is fired, which prestresses a spring which turns the rotor into the arming position after its release.
  • the basic requirement of such a detonator is thus advantageously met in a simple manner, that no potential energy is used for the removal of the spark plug lock device.
  • the spring is in the fully secured position when the system is secured and only receives its operating energy when the first spring arm is tensioned by the axial movement of the second recoil bolt.
  • the rear-firing pin system 1 is mounted between two plates 14 and 15 arranged at a fixed distance from one another.
  • This recoil pin system consists of a first recoil pin 5, which is inserted with its upper shaft 16 in the upper plate 14 and axially against a spring 17 supported on the lower plate 15.
  • This recoil bolt 5 also has a cone 4, which is located between an upper collar 18 and a lower collar 19.
  • another recoil pin 20 is inserted in the housing, which in turn is axially supported against a spring 21 supported on the lower plate 15.
  • the two recoil bolts 5 and 20 are coupled to one another by a ball 11.
  • a U-shaped leg spring 2 is inserted around a bolt 12 arranged in the housing, the first spring leg 3 of which rests with its end on the lower part of the cone 4 of the recoil pin 5 in the securing of the igniter.
  • the second spring leg 6 of the leg spring lies in a recess 7 on the outer surface of the rotor 8. This spring leg 6 is supported in particular on the shorter wall 13 lying on the radius of the rotor 8.
  • the rotor 8 also has a focus lock 9 and is in drive connection with an inhibitor 10 formed from a plurality of wheels.
  • a slide can also be used.
  • a correspondingly arranged pin can be provided, against which the spring leg 6 of the leg spring 2 rests.
  • the leg spring 2 In securing the detonator, the leg spring 2 is not under tension and is protected against unintentional tension by securing the recoil pin system 1. There is therefore no spring force at the rotor 8. This meets STANAG 3525's requirement that no potential energy be used to remove the spark plug lock device.
  • the recoil pin system 1 triggers and the recoil pin 5 biases the spring leg 3 of the U-shaped leg spring 2 as it moves downward through the cone 4.
  • the spring leg 6 of the U-shaped leg spring 2 moves against the wall 13 in the recess 7 of the rotor 8. The rotor 8 is thus turned into the arming position, where it is fixed via the arming lock 9 becomes.
  • the escapement 10 connected to the rotor controls the rotary movement of the rotor in the arming position.
  • the inhibitor 10 itself consists of the armature 22, which is rotatably arranged on the shaft 23 and is in engagement with the star wheel 24.
  • the pinion 25, which is rotationally fixed on the same shaft with the star wheel 24, meshes with the intermediate wheel 26, which in turn is arranged on the same shaft with the second pinion 27 in a rotationally fixed manner.
  • the pinion 27 is operatively connected to the toothed segment 28, as a result of which the disk 29, which is rotationally fixed on the same shaft as the toothed segment, performs a limited rotational movement.
  • the rotor 8 When the disk 29 rotates, the rotor 8 is uncoupled from the inhibitor mechanism 10 when the flattened area of the disk 29 is above the recess 30 of the rotor. The rotor then swivels into its focus position, the spring leg 6 serving as the drive.
