Definitions

  • the object which is to be achieved with the present invention is to create a impact detonator which is capable of defusing itself if the projectile is not detonated immediately when it hits the target.
  • a bolt is preferably provided as a means for triggering the inhibiting mechanism, which locks the inhibiting mechanism in a first position, which releases the inhibiting mechanism in a second position and which, due to its inertia when the projectile is delayed by impact, shifts from the blocking position into the release position.
  • an igniter head 12 is fastened to an igniter housing 10 of the impact igniter 11 by means of a thread 13.
  • the detonator head 12 is screwed into a floor (not shown) with the aid of a second thread 14.
  • a sleeve 16 with an amplifier charge 17 and with a dud insert 18 is fastened with the aid of a further thread 15.
  • An ignition pin 19 is slidably mounted in the ignition head 12, of which only the tip is indicated in the drawing. This firing pin 19 is used to pierce a squib 20, the is located in a slide 21.
  • This slide 21 can shift from the safety position shown in the direction of arrow A to its armed position, such that the squib 20 reaches the area of the firing pin 19.
  • a housing 22 is inserted, in which the essential organs of an impact detonator 11 are located, in particular an inhibitor mechanism 23, which ensures the safety of the detonator's fore-pipe.
  • This escapement 23 means that the slide 21 can only move into its armed position when the projectile is no longer in the vicinity of the gun from which it was launched after the launch.
  • the detonator housing 10 has a central bore 24 in which an explosive core 25 is located. This explosive core 25 is ignited by the squib 20 and in turn ignites the booster charge 17 through the dud insert 18.
  • a trigger bolt 26 is displaceably mounted in the detonator housing 10. This release bolt 26 is supported with its front end on the slide 21 as long as it is in its safety position. The rear end of the release pin 26 protrudes into the dud insert 18. As will be described further below, the connection between the explosive core 25 and the booster charge 17 is interrupted as soon as the trigger bolt 26 slides out of the dud insert 18.
  • a rotor 28 is located in a housing 27 of the dud insert 18 and can be rotated about an axis 29.
  • this rotor 28 there is an explosive core 30 which is arranged parallel to the axis 29.
  • the upper end of this explosive core 30 protrudes from the rotor 28 and is surrounded by a sleeve 31.
  • a further explosive core 32 is arranged in the cylindrical housing 27, the axis of which coincides with the axis of the housing 27. In the position shown tion of the rotor 28, the axes of the two explosive souls 30 and 32 coincide. In this position, the explosive core 25 shown in FIG. 1 is able to ignite the booster charge 17 via the two explosive core 30 and 32.
  • a disk 33 which has the same diameter as the rotor 28 and is provided with a toothed segment 40.
  • the disc 33 is rigidly connected to the axis 29.
  • the two ends of the axis 29 are rotatably mounted on the one hand in the housing 27 mentioned and on the other hand in a housing cover 34.
  • the rotor 28 is rotatably mounted at the bottom with a sleeve-like projection 35 in the housing 27 and at the top it is rotatably mounted about a pin 36 of the disk 33.
  • the axis 29 is surrounded by a helical spring 37, which is anchored with its lower end 38 in the housing 27 and with its upper end 39 in the disk 33.
  • This spring 37 is biased and tends to pivot the disc 33 clockwise, ie in the direction of arrow B in Figure 3.
  • the disc 33 has a bore 41 and the cover 34 has a bore 42, which are aligned with one another in the position of the disc 33 shown and through which the already mentioned release bolt 26 projects.
  • the prestressed spring 37 cannot rotate the disk 33 in the direction of arrow B.
  • this disk 33 also has a curved elongated hole 43 (FIG. 3) through which the sleeve 31 of the explosive core 30 projects.
  • the disk 33 engages via the toothed segment 40 with a toothed wheel transmission which consists of four toothed wheels 44, 45, 46 and 47 (see FIGS. 3 and 4), by means of which a restlessness 48 is driven.
  • the four gear wheels 44, 45, 46 and 47 are rotatably supported about axes 49, as is the restlessness 48.
  • FIGS. 3 and 4 there is also a securing bolt 50 in the rotor 28, which has a conical tip 51 protrudes into a bore 52 of the housing 27.
  • This securing bolt 50 is supported with its upper end opposite the tip 51 on the disk 33, but can be pushed into the bore 43 according to FIG. 4 so that the tip 51 can come out of the bore 52 to release the rotor 28 , which is secured against rotation as long as the tip 51 protrudes into the bore 52.
  • the release pin 26, which can also be referred to as a sensor pin, has a groove 53 at its lower end.
  • the bore 41 of the disk 33 has a conical surface 54.
  • the prestressed spring 37 tends to turn the disk 33 in the direction of arrow B according to FIG. 3, the conical surface 54 is pressed against the groove 53 of the release bolt 26, causing the sensor pin 26 to slide out of the bore 41 unintentionally is difficult.
  • the firing pin 19 When the bullet hits the target, the firing pin 19 is immediately pushed against the squib 20, this is ignited and the booster charge 17 is ignited via the firing chain, consisting of the three explosive souls 25, 30 and 32, long before the rotor 28 of the dud insert 18 in was turned to its safety position in the manner described.
