Ammunition cartridge with electrically ignited propellant charge

摘要

The device has a propulsive charge casing (2) and an electrothermal igniter (4). The casing is connected to a metal floor (3). An internal insulator (15) in shape-locking contact with the casing floor protrudes through the floor via an opening. The insulator encloses a protruding electrical contact part (5) contacted by an external high voltage electrode and in one piece with a contact plate in shape-locking contact with the insulator.
