Definitions

  • the invention relates to an impact detonator with a primer according to the preamble of claim 1.
  • an impact detonator with a detonator which can be pierced from the back of the detonator with a spring-operated firing pin.
  • the impact detonator has a mechanical delay device with a blocking body which, in its blocking position, lies on the one hand in recesses in the firing pin and on the other hand in recesses of a stationary detonator part.
  • two inertial sleeves arranged one behind the other coaxially with the igniter part, which release the blocking bodies after the impact delay has ended.
  • the tapping energy required for initiation is no longer available via an inertia-dependent hammer with a defined ignition delay time. Accordingly, a preloaded compression spring is provided in the aforementioned patent. After the locking body is unlocked, it strikes the firing capsule in firing pins.
  • the object of the invention is therefore to provide a strike detonator for a mechanical, highly sensitive ignition system which initiates initiation with sufficient ignition delay time in the case of thin targets, flat angles of incidence and long combat distances.
  • the firing pin has the mass required for inertia-dependent ignition with high impact energy.
  • the proportion of the spring's propulsive force is negligible.
  • the preloaded compression spring in conjunction with low friction losses during the movement of the firing pin ensures that the firing takes place with certainty via the firing pin.
  • the ignition delay time which is decisive for the degree of destruction of the target, can be determined in a simple manner. With a low impact energy there is a longer ignition delay time than with a high impact energy. This is due to the fact that when the impact energy is low, the securing sleeve must first be at the rear, housing-fixed stop so that the firing pin can pierce the primer with the required energy. In contrast, with a high impact energy, the shorter ignition delay time is ensured by the distance of the recess fixed to the housing from the securing or basic position of the mechanical delay device.
  • FIG. 1 shows a simplified representation of a cross section through an igniter in the "safe" position and FIG. 2 shows the igniter according to FIG. 1 in the ignition position.
  • An impact detonator 1 consists of a housing 2 with recesses 3, 4 and bore 5, a cover 7 screwed at 6, a base body 8, a securing sleeve 9, a centrifugal fuse 10, a rotor 11 with a detonator 12 and a firing pin 13.
  • the firing pin 13 consists of a piston sleeve 14 with a riveted firing needle 15 and a compression spring 16 which is clamped between a collar 17 and a plate 18.
  • the piston sleeve 14 also has a stop 20, a space 21 for a compression spring 22 and recesses 23 for balls 24.
  • the compression spring 22 fixes the piston sleeve 14 on the balls 24 in the starting position.
  • the balls 24 are arranged in recesses 30. They are delimited on the outside by a guide wall 31 and on the inside by the compression spring 22.
  • the securing sleeve 9 is provided with a bottom 33 and a bore 34.
  • an axial stroke of the securing sleeve 9 and the firing pin 13 coupled via the balls 24 takes place in the direction of arrow 45.
  • the axial stroke ends in a first phase when the balls 24 enter the recess 40 Tip 46 has reached the position labeled 47 at the end of the first phase.
  • the compression spring strikes the securing sleeve 9 against the direction of the arrow 45 up to the stop on the cover 7 and then in the third phase causes the firing pin 13 to advance until the detonator 12 is tapped as shown in FIG. 2.
  • the ignition delay time is added up from the times of phases 1 to 3.
  • the inertia of the firing pin 13 outweighs the effect of the compression spring 16. This results in a very short ignition delay time.
  • the decisive factor is the distance 49, which corresponds approximately to 1.5 times the diameter 44 of the balls 24.
  • the length 43 of the recess 40 ensures that - due to the greater inertia of the firing pin 13 than the inertia of the securing sleeve 9 - the balls 24 can also enter the recess 40.
  • the impact detonator is suitable for both swirl projectiles, low-swirl and swirl-free projectiles. In the case of low-swirl and swirl-free projectiles, appropriate safeguards must be provided for the firing pin.
