Abstract
A fuse assembly that includes a low energy exploding foil initiator (LEEFI) located in a housing thereof. The LEEFI is supported in the housing by a sleeve made of a compliant material that protects the LEEFI by dampening shocks and vibrations applied to the housing. At least a portion of the LEEFI is press-fit into the sleeve such that an interference fit exists between an outer cylindrical wall of the LEEFI casing and in inner wall of the housing. The sleeve includes a latch assembly at one end having a plurality of tabs that are circumferentially spaced-apart from one another. Each of the plurality of tabs includes a cantilever beam having a head, the head including a bottom surface pressed against a top surface of the external annular flange of the LEEFI casing.
