Claim Text:
1. A multi-step separator for a fuze that is configured to be disposed in an ogive of a projectile in a cartridge-type military munition, wherein the fuze includes a detonator for initiating an energetic sequence resulting in a high-order detonation of an explosive device in the projectile, said multi-step separator comprising a fuze-munition interface device for retaining the fuze in a confined, close relationship with the explosive device and for releasing the fuze when and if it is subjected to a first elevated temperature that may cause it to prematurely detonate the explosive device, said interface device comprising a separating device including a fusible ring disposed between the fuze and the explosive device for separating and physically distancing the fuze from the explosive device when and if the fuze is released at said first elevated temperature, wherein said fusible ring comprises a compressed coil spring embedded in a first solid, fusible material that melts at said elevated temperature and releases the spring when it melts.
