Abstract
A safety and arming device (10) for a spinning projectile fuze, which has a fuze housing (12), which is in the form of a pot, and a bearing body (14) with a booster charge (16). A spherical rotor (42) with a detonator (44) is mounted between the fuze housing (12) and the bearing body (14). A radial groove (22) is formed in the fuze housing (12), and an annular groove (46) is formed in the rotor (42). A holding ring (28) is forced against the annular groove (46), which is axially offset with respect to the radial groove (22), when the safety and arming device (10) is in the safe position. The holding ring (28) is designed with a separating slot (30) and a further, shorter slot (32). The separating slot (30) and the further slot (32) extend at the same distance apart in the circumferential direction of the holding ring (28) and define annular segment jaws (40). The spring device (48) has a pair of cup springs (58), which jointly form a horizontal V-shaped spring profile.
