Definitions

  • the invention relates to a cartridge with a propellant charge sleeve and an electrothermal Ignition device, wherein the propellant charge sleeve with an existing metal Sleeve bottom is connected.
  • the propellant powder is ignited by forming arcing within the propellant powder.
  • a wire-shaped conductor used to ignite the powder from such a high Current is flowing through that the corresponding wire evaporates explosively. The The arc that forms during this process then ignites the surrounding propellant powder on.
  • Such a cartridge is known for example from DE 199 36 649 A1, wherein a well insulated electrical contact piece thanks to the metal base of the sleeve is guided, which is essentially on the outside over the bottom piece of the sleeve bottom protrudes and can be contacted by a weapon-side high-voltage electrode is.
  • the contact piece is made by a relatively solid molded insulating part supported laterally and is connected to a contact disc on which several wire-shaped conductors guided through the propellant powder are attached.
  • a disadvantage of this known cartridge is, among other things, that the outside protruding contact piece an automatic operation of the corresponding weapon system, especially with wedge locks, cannot be realized. It also takes to support the contact piece solid molded insulating part relatively much space inside the cartridge, which calls for a high loading density of the propellant powder opposes.
  • the invention has for its object to provide a cartridge that is easy to manufacture, which allows automatic operation of weapon systems, as he essentially does is also possible when using conventional cartridges.
  • the invention is essentially based on the idea of designing the contact piece in such a way that that it does not protrude from the outside of the front surface of the base piece and that it forms the inside of the contact disc, which is formed over a sleeve-bottom Supports insulator of relatively small wall thickness over a large area on the propellant charge sleeve, so that a correspondingly massive insulator molding can be omitted.
  • the cartridge according to the invention in which the insulation of the high-voltage live Parts fully integrated in the sleeve base are particularly suitable for modern ones Armored cannons with wedge lock.
  • the contact disk on its outer edge is designed as a sealing lip, so that the shot avoids that powder gases between the insulator and the contact disk.
  • this can be done with the insulator and this with the Be glued to the bottom of the sleeve.
  • the sealing lip of the Sleeve base formed in one piece with the insulator.
  • the connection (adhesion) to the base of the sleeve becomes simultaneously and made to the contact disc.
  • Fig. 1, 1 is a large-caliber cartridge (e.g. for firing from an armored weapon) designated, which is a combustible propellant charge sleeve 2 and one made of steel Sleeve base 3 with sealing lip 3 'attached to it on the front side.
  • a large-caliber cartridge e.g. for firing from an armored weapon
  • a combustible propellant charge sleeve 2 and one made of steel Sleeve base 3 with sealing lip 3 'attached to it on the front side.
  • the cartridge 1 is provided with an electrothermal ignition device 4. This exists essentially from an electrical contact piece 5, which on the one hand in a Recess 6 of the bottom piece 7 of the sleeve base 3 protrudes and on the other hand with a large, extending over the entire inside 8 of the bottom piece 7 Contact disc 9 is connected.
  • the contact disk 9 has on its outer edge a sealing lip 10.
  • there is one end 11 on the contact disk 9 two wires 12 used to ignite arcs attached.
  • the other End 13 of the two wires 12 is fastened to a contact ring 14 of the propellant charge sleeve 2.
  • the contact disk 9 and the sleeve bottom 3 are formed by a sleeve bottom high voltage resistant insulator 15 electrically isolated from each other.
  • This forms an annular region 15 'within the recess 6 of the base piece 7 and is supported on the outside on the inner wall 16 of the recess 6. Also encloses the annular region 15 'of the insulator 15 projects into the recess 6 Contact piece 5.
  • Cartridge 1 denotes a weapon barrel and 19 a base piece, in which there is a wedge lock with locking wedge 20.
  • the wedge 20 is an axially displaceable, which is surrounded by insulation 21 arranged high-voltage electrode 22. This is connected via a feed line 23 to a not shown power source connected.
  • the high voltage electrode 22 After closing the locking wedge 20 (Fig.2), the high voltage electrode 22 automatically moved towards the contact piece 5 of the cartridge 1 and on the front pressed into a recess 24 of the contact piece 5 (Fig.3). Doing so at the same time the insulation 21 of the high-voltage electrode 22 on the ring-shaped Area 15 'of the insulator 15 of the cartridge 1, so that the electrical connection between the high voltage electrode 22 and the contact piece 5 is completely insulated.
  • the sealing lip 3 'of the sleeve base 3 is connected in one piece to the insulator 15. This can be done easily can be achieved that with the vulcanization of the sealing lip 3 'and thus also the Insulator 15 at the same time a connection (adhesion) to the sleeve bottom 3 and Contact disc 9 is made.
