Plastic encapsulated energetic material initiation device

An initiator comprising:

• a housing formed of plastic, the housing defining an aperture that is adapted to receive an energetic material;
• and
• a chip assembly that is adapted to initiate at least one of a combustion event, a deflagration event and a detonation event in the energetic material, the chip assembly including an electrically-actuated chip and a pair of electric leads that are electrically coupled to the electrically-actuated chip, the electric leads extending through the housing and being adapted to couple the electrically-actuated chip to a fireset circuit, the electrically-actuated chip being partially encapsulated in the housing and extending into the aperture in the housing;
• wherein each of the electric leads comprises a plurality of spring arms that are electrically coupled to a corresponding contact on the electrically-actuated chip so that electrical contact between each electric lead and its associated electrical contact is made at a plurality of discrete points.

An initiator comprising:

• a housing formed of plastic, the housing defining an aperture that is adapted to receive an energetic material;
• and
• an exploding foil initiator having a bridge and a pair of contacts that are adapted to cooperate in transmitting electrical energy across the bridge, a portion of the exploding foil initiator radially outwardly of the bridge being encapsulated in the plastic that forms the housing;
• and
• a plurality of electric leads coupled to the contacts.

• a plurality of electric leads coupled to the contacts, at least a portion of the electric leads are encapsulated in the plastic that forms the housing;
• an initiation charge formed of a secondary explosive, the initiation charge being received in the aperture and positioned to receive energy released by the exploding foil initiator to initiate a detonation event in the initiation charge;
• and
• a reinforcing ring received in the aperture and disposed between the housing and the initiation charge, the reinforcing ring being formed of a conductive material and is disposed axially in-line with at least one of the electric leads, at least one of the contacts, or at least one of the electric leads and at least one of the contacts, and wherein the plastic that forms the housing electrically insulates the reinforcing ring from the contacts and the electric leads.
