Mechano-electrical fuse for a hand grenade

摘要

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 ).
