摘要:
An initiator that includes a substrate, an exploding foil initiator and a first switch. The exploding foil initiator coupled to the substrate and includes a bridge and a first bridge contact. The first switch has a first contact and a first insulator. The first contact is coupled to the substrate and spaced apart from the first bridge contact by a gap. The first insulator is disposed in the gap. The first switch is operable in an actuated mode in which electrical energy transmitted between the first contact and the first bridge contact is transmitted through the first insulator.
摘要:
A device having an initiator and an integrated planar switch. The initiator has a base, an initiating element that is coupled to the base, a first element pad, which is electrically coupled to a first side of the initiating element, and a second element pad, which is electrically coupled to a second side of the initiating element opposite the first element pad. The integrated planar switch has a source pad and a return pad. The source pad is coupled to the base and is spaced apart from the first element pad by a first gap distance to define a first gap therebetween. The return pad is coupled to the base and is spaced apart from the second element pad by a second gap distance to define a second gap therebetween.
摘要:
An igniter assembly with a housing, an initiator, an input charge, a first barrier, a second barrier, and an output charge. The input charge is formed of a secondary explosive and disposed adjacent the initiator. The first barrier cooperates with the housing to form a chamber into which the input charge is received. The second barrier is disposed on a side of the first barrier opposite the input charge and combusts in response to energy released during detonation of the input charge. The output charge is formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier. The output charge can combust in response to energy released during combustion of the second barrier. The housing and the first barrier cooperate to isolate the output charge from heat and pressure generated by the input charge if the input charge is cooked-off.
摘要:
An igniter assembly that includes a housing, a secondary explosive input charge, a pyrotechnic output charge and a barrier system that is disposed between the input charge and the pyrotechnic output charge. The barrier system shields the pyrotechnic output charge from energy released by the input charge to prevent the output charge from being cooked-off or initiated unless the input charge is detonated.

A switch device having a base, a first electrically conductive pad coupled to the base, a second electrically conductive pad coupled to the base, a first electrically conductive projection and a second electrically conductive projection. The second electrically conductive pad is spaced apart from the first electrically conductive pad by a first predetermined distance. The first electrically conductive projection is coupled to the first electrically conductive pad and extends into the first gap. The second electrically conductive projection is coupled to the second electrically conductive pad and extends into the first gap. The second electrically conductive projection is spaced apart from the first electrically conductive projection by a second predetermined distance. The first and second electrically conductive projections form an electrical interface.
摘要:
An initiator with a housing formed of plastic and a chip assembly for initiating at least one of a combustion event, a deflagration event and a detonation event. The chip assembly includes an electrically-actuated chip and a pair of electric leads that extend through the housing and are configured to couple the electrically-actuated chip to a fireset circuit. The electrically-actuated chip is partially encapsulated in the housing. A method for forming an initiator is also provided.

摘要:
An initiator assembly having a base, first and second conductive elements, a first electrically insulating member and an energetic material. The first conductive element, which is configured to receive an electrical input, is coupled to the base and includes a tip. The first electrically insulating member is disposed over the tip. The second conductive element has a bridge that is disposed over the first electrically insulating member. The bridge is configured to vaporize in response to transmission of the electrical input from the tip of the first conductive element to the bridge. The energetic material is disposed over the bridge. Energy produced during vaporization of the bridge is transmitted to the energetic material to initiate at least one of a combustion event, a deflagration event and a detonation event in the energetic material. A method for operating an initiator assembly is also provided.
