Abstract: An initiator assembly that includes an end plate, a plurality of terminals, a plurality of epoxy plugs, an insulator layer and an exploding foil initiator. The end plate is formed of aluminum and has a plurality of first terminal apertures formed there through. Each of the terminals is received through a corresponding one of the first terminal aperture. Each epoxy plug is received in an associated one of the first terminal apertures and is sealingly engaged to the end plate and to an associated one of the terminals. The insulator layer is received over the end plate. The exploding foil initiator is abutted against the insulator layer and has a bridge and a pair of initiator contacts. Each of the initiator contacts is electrically coupled to a corresponding one of the terminals.

Abstract: An initiation system that includes an initiator chip having an electrically conductive bridge, a flyer layer coupled to the initiator chip and overlying the bridge, a housing, an energetic material and a lid. The housing is formed of a first plastic material that is overmolded onto the initiator chip such that the initiator chip is at least partly encapsulated into the first plastic material to thereby fixedly couple the initiator chip to the housing. The housing defines a cavity having a first end and a second, open end that is opposite the first end. The initiator chip is disposed proximate the first end of the cavity. The energetic material is disposed in the cavity. The lid is at least partly formed of a second plastic material and is fixedly and sealingly coupled to the housing to close the open end of the cavity.

Abstract: An initiation system that includes a housing, an exploding foil initiator and a securing structure. The housing is formed of plastic and defines a cavity with an open end. The exploding foil initiator assembly has an initiator chip, a flyer layer and a barrel. The initiator chip has an electrically conductive bridge and is at least partly encapsulated in the plastic of the housing. The flyer layer has a first side, which faces the bridge, and a second side opposite the first side. The barrel is disposed between the second side of the flyer layer and an end of the cavity opposite the open end. The securing structure is formed of metal and is partly encapsulated in the plastic of the housing. The securing structure is disposed about the cavity and extends away from the housing about a perimeter of the open end of the cavity.
