  • Electrical power feed assembly for electrothermal gun and cartridge
    Patent number: 5544588
    Abstract: An electrical power feed assembly (12) for supplying high current to an electrothermal gun has first and second electrical connectors (38) and (42) with associated contact portions (40) and (44) for engaging and plastically deforming first and second side contacts (20,22) on a cartridge (14) to provide firing while maintaining the electrical contact without any arcing. The first connector (38) has a curved contact portion (40) that provides an interference fit to plastically deform the first contact (20) and establish the electrical contact as the cartridge (14) is inserted into the gun. The second connector (42) has a pair of curved knife edges (48) that engage and plastically deform the second contact (22) of the cartridge to establish and maintain the electrical contact under spring action of the second connector and by operation of a cam mechanism (50) of a breech block (26) of the gun.
    Type: Grant
    Filed: April 13, 1995
    Date of Patent: August 13, 1996
    Assignee: General Dynamics Land Systems, Inc.
