Abstract
A stab type fuze mechanism, such as the 30 mm M759 fuze mechanism, which utilizes a generally horse shoe shaped configuration anti-setback spin clip initially lodged in a grove within the body of a target sensing probe, but extending partially therefrom, which extending part rests against a ledge within the aluminum o-give—located rearward from the target sensing probe; thereby preventing the target sensing probe from moving rearward within the fuze during firing and setback. After firing, with the onset of spin, the anti-setback spin clip will open, expanding away from, out of, and clear of the grove and into a cylindrical channel in which the target sensing probe is lodged. Due to a thinned area at the apex of the clip, the expansion of the anti-setback spin clip will be a plastic deformation and the clip will remain expanded. With the expanded clip entirely clear of the grove—when the cartridge impacts its target, either a hard target, or a soft target, the obstructed forward travel of the cartridge will force the target sensing probe rearwards to impact the firing pin located immediately rearward thereof; thereby, forcing the firing pin rearward and initiating the firing train of the fuze, and subsequently, igniting the secondary explosive within the cartridge to cause detonate thereof.
