An initiator assembly that includes a header body, a frame member, a plurality of terminals, an initiator chip, a plurality of contacts, and a support member. The frame member is coupled to the header body and defines an interior aperture. The terminals are received through the header body and the frame member. The initiator chip is received in the frame member and has a plurality of lands, a conductive bridge and a flyer that is disposed over the conductive bridge. Each of the contacts is soldered to an associated one of the terminals and an associated one of the lands. The support member is formed of plastic and encapsulates the frame member, the plurality of contacts, and a portion of the initiator chip. The support member forms a barrel aperture over the flyer. The input charge is formed of a secondary explosive and is disposed in-line with the barrel aperture.

Initiator assembly that is resistant to shock

An initiator assembly with a housing, an exploding foil initiator, an input charge, which is formed of an energetic material, and a support plate. The exploding foil initiator has a base coupled to the housing, a bridge mounted to the base, a flyer overlying the bridge, and a barrel. The barrel is coupled to the base and defines a channel through which the flyer traverses when the exploding foil initiator is activated. The support plate supports an axial end of the input charge and is interposed in a path of travel of the flyer between the bridge and the input charge. A related method is also provided.

High G-force resistant initiator assembly having an exploding foil initiator

An apparatus for detonating an initiation charge that is formed of a secondary explosive, such as triaminotrinitrobenzene (TATB). The apparatus includes an exploding foil initiator, which can have a relatively small flyer that is suited to initiate a detonation event in the initiation charge.
