Tail fuze

Abstract

A tail fuze ( 10 ) is described having an electrical detonator ( 12 ), a fuze needle ( 14 ) which is associated with the electrical detonator, a piercing fuze ( 16 ) which can be moved into line with the fuze needle ( 14 ) and is intended for a fuze booster ( 28 ), wherein the fuze needle ( 14 ) has a mass body ( 32 ) on which a restraint spring ( 34 ) is provided. If the electrical firing fails, then the piercing fuze ( 16 ) is fired on striking the ground by the fuze needle ( 14 ) as a result of the inertia of the mass body ( 32 ).

1 . A tail fuze having an electrical detonator ( 12 ), a fuze needle ( 14 ) which is operatively associated with the electrical detonator, a piercing fuze means ( 16 ), which is movable into line with the fuze needle ( 14 ) and is provided for a fuze booster ( 28 ), and wherein the fuze needle ( 14 ) has a mass body ( 32 ) having a restraint spring ( 34 ) arranged thereon. 
   
   
       2 . A tail fuze according to  claim 1 , wherein the restraint spring ( 34 ) is provided on a side of the mass body ( 32 ) facing the electrical detonator ( 12 ). 
   
   
       3 . A tail fuze according to  claim 1 , wherein the restraint spring ( 34 ) is formed by an annular spring. 
   
   
       4 . A tail fuze according to  claim 2 , wherein the restraint spring ( 34 ) is formed by an annular spring. 
   
   
       5 . A tail fuze according to  claim 1 , wherein the piercing fuze means ( 16 ) is located on a rotor ( 18 ), which has a safe-separation distance device ( 20 ). 
   
   
       6 . A tail fuze according to  claim 5 , wherein the safe-separation distance device ( 20 ) has spring bolts ( 22 ,  24 ), and a blocking element ( 26 ) positioned between the spring bolts.
