Abstract
A strike pin assembly for a fuse assembly in which the strike pin assembly is maintained in a locked position by a holding force of a filament and an interference provided by a plurality of retention bodies. Upon a breakage of the filament, such as, for example, in response to heat generated by operation of a fuse element, a trigger can be displaced via a first biasing force in a distal direction such that the trigger is positioned at a location that does not impede an inward displacement of a plurality of retention bodies from a recess of a firing pin. Upon the inward displacement of the retention bodies, a second biasing force can displace the firing pin in the distal direction such that a portion of the firing pin can protrude out from an adapter of the strike pin assembly.
