Definitions

  • the invention relates to an adaptation cartridge for a push-in tube system for firing sub-caliber ammunition from a larger-caliber weapon barrel, with a centrally inserted cartridge chamber and a firing pin sleeve arranged coaxially thereafter, which is connected on the closure side to the cartridge chamber by positive locking and has a safety rod arranged axially parallel to the firing pin, which is under the action of a compression spring and receives a slide.
  • An adaptation cartridge for a plug-in pipe system of the aforementioned type is known from DE 33 39 745 C2.
  • the firing pin is moved mechanically against the ignition pin, which is under the action of a compression spring and which in turn pierces the primer of a cartridge.
  • Kinetic energy is therefore required to ignite the ammunition for the mechanical ignition.
  • the mechanical ignition is triggered by the original lighter of the larger-caliber ammunition, which is screwed into the firing pin sleeve from behind. When this original lighter (primer) is fired, an excess pressure builds up in the firing pin sleeve, which accelerates a firing pin. This firing pin finally ignites the sub-caliber ammunition mechanically.
  • this object is achieved in that the slide engages in a guide which is drive-connected to the firing pin, which rests on the primer of the cartridge when the breech is closed and receives an electrical ignition energy from the weapon via a firing pin.
  • the securing rod can be moved in the slide against the action of the compression spring by the closing closure in the direction of the cartridge, the slide being displaceable within a recess in the firing pin sleeve at most up to a rear stop of a securing ring.
  • the guide can be formed from an electrically insulating material. Furthermore, the guide can have an annular groove for the engagement of the slide and can slide with its outer lateral surface in a cylindrical recess in the firing pin sleeve.
  • the combustion residues which contaminate the ignition pin and can lead to a defect, are basically avoided because an electric ignition is used.
  • the primer is omitted, which leads to a significant reduction in costs.
  • the ignition energy is now passed through the firing pin guide without resistance and electrically ignites the igniter of the sub-caliber ammunition.
  • the entire firing pin is advantageously designed to be liftable with the aid of the safety rod.
  • the adaptation cartridge 1 essentially consists of the tubular jacket 2, preferably of a plastic, the cartridge chamber 3, the cartridge chamber tube 4 and the firing pin sleeve 5.
  • the cartridge chamber 3 is arranged centrally in the jacket 2.
  • the cartridge chamber tube 4 is arranged in a coaxial arrangement with the cartridge chamber 3 in the direction of the weapon breech 6.
  • the cartridge chamber tube 4 can be an integral extension of the cartridge chamber 3. It can also be designed according to the embodiment shown as a separate component which is connected to the cartridge chamber 3 by positive and non-positive engagement, for example by screwing.
  • the cartridge bearing tube 4 is supported axially at the end on the closure side against a flange ring 7 of the adaptation cartridge 1.
  • the firing pin sleeve 5 has a central bore 8 into which the firing pin 9 and the firing pin spring 10 are inserted.
  • the firing pin 12 is provided in the direction of the cartridge 11, which is axially movable and slidably in a guide 13 made of an electrically insulating material with its outer surface 14 in a cylindrical recess 15 of the firing pin sleeve 5.
  • the guide 13 and the ignition pin 12 are in a resilient connection, so that when the guide 13 moves axially, the ignition pin 12 is carried in the same direction.
  • the spring 10 takes it up.
  • the firing pin 12 is under spring pressure of the spring 10 on the primer 29.
  • a safety rod 17 is inserted axially movable in a cylindrical recess 16 of the firing pin sleeve 5.
  • the safety rod 17 is at its end face 18 against a compression spring 19 which is provided in the blind bore 20 in the axial extension of the cylindrical recess 16.
  • the securing rod 17 has a slide 22 in a fixed connection, which can be displaced in a radial recess 23 up to a maximum against a front stop 24 and a rear stop 25.
  • the slide 22 engages with a nose 26 in an annular groove 27 of the guide 13, whereby there is a firm, resilient coupling between the safety rod 17 and the ignition pin 12.
  • the connection between the ignition pin and the igniter is now established.
  • the electrical ignition takes place in the usual way in the weapon breech, where an electrical pulse is transmitted to the firing pin 9 and from there to the firing pin 12. Due to the use of electrically insulating material, the electrical impulse cannot jump from the guide 13 onto the safety rod.
  • the weapon breech 6 opens so that the safety rod 17 can move back to the starting position.
  • the ignition pin 12 is also withdrawn and the contact is broken.
