Abstract

A mechano-electrical fuse (10) for a hand grenade (76), which has a spring element for the storage of mechanical energy and which has a drive device connected to the spring element for driving an electrical generator (28) through mechanical energy which is stored in the spring element. The electrical generator (28) is connected through an electronic delay circuit (56) with a detonator (46), with which a booster charge (48) is associated. A barrier (40) is provided between the detonator (46) and the booster charge (48). The spring element is formed by a tensioning spring (24) associated with the handle lever (18) of the hand grenade (76). The drive device has a taut cable line (68) which is fixed at one end (70) to the generator shaft (30) and wound with a number of turns (72) around the generator shaft (30). The second end (74) of the cable line (68) is mounted to the handle lever (18). Fixed to the generator shaft (30) is a flywheel mass (32) which is fixed releasably by a shearing element (92) in a fuse housing (16) of the mechano-electrical fuse (10).
