Gun for firing electrically-ignitable cartridges containing electronic components

A gun for firing electrically-ignitable cartridges that contain electronic components, and in which an ignition contact is disposed on a cartridge bottom for producing a connection to an external current source, and a signal contact is disposed on the cartridge bottom for connecting the electronic components to an external electronic control and evaluation device, said gun including:

• a barrel that is seated in a gun cradle;
• a breech ring secured to a breech end of the barrel;
• a wedge-type breech block mounted in the breech ring for displacement transverse to a longitudinal bore axis of a barrel bore of the gun;
• an ignition and signal-transmission unit mounted in the breech block for displacement in an axial direction of the barrel, counter to a force of a spring, from a retracted position into an extended position by a breech-block unit;
• said ignition and signal-transmission unit comprising a housing that includes two parallel, axially extending guides, and respective spring-loaded, needle-shaped first and second contact devices seated in said axial guides for displacement such that, in the extended position of the ignition and signal-transmission unit when the breech block is in a locked position, the first contact device is pressed against the ignition contact of a cartridge and the second contact device is pressed against the signal contact of a cartridge;
• and
• on a side facing away from a cartridge and toward the breech-block unit, the two needle-shaped contact devices are supported by respective compression springs against one of a housing of the ignition and signal-transmission unit and a part that is connected to the housing for movement therewith.
