Contactor device integrating pyrotechnic disconnect features

A contactor device, comprising:

• a housing;
• internal components, said internal components comprising:
• fixed contacts electrically isolated from one another, said fixed contacts at least partially surrounded by said housing;
• one or more moveable contacts, said one or more moveable contacts allowing current flow between said fixed contacts when said one or more moveable contacts are contacting said fixed contacts;
• a shaft structure connected to said one or more moveable contacts;
• and
• contact structures electrically connected to said internal components for connection to external circuitry;
• and
• pyrotechnic features configured such that when a threshold current level passes through said internal components, said pyrotechnic features activate and push said movable contacts away from said fixed contacts such that said moveable contacts separate from said fixed contacts.

• internal components, said internal components comprising:
• fixed contacts electrically isolated from one another, said fixed contacts at least partially surrounded by said housing;
• one or more moveable contacts, said one or more moveable contacts allowing current flow between said fixed contacts when said one or more moveable contacts are contacting said fixed contacts;
• a shaft structure connected to said one or more moveable contacts;
• and
• contact structures electrically connected to said internal components for connection to external circuitry;
• and
• pyrotechnic features configured such that when a threshold current level passes through said internal components, said pyrotechnic features activate and interact with said shaft structure, such that said shaft structure changes configuration, such that said moveable contacts separate from said fixed contacts, wherein said housing is hermetically sealed, wherein said housing comprises a separate internal compartment within said housing, wherein said pyrotechnic elements comprise a pyrotechnic charge and said contactor device further comprises a piston structure near said pyrotechnic charge, wherein said piston structure is near said shaft structure and activation of said pyrotechnic charge causes said piston structure to push said shaft structure substantially into said separate internal compartment, wherein said piston structure comprises sufficient dimensions to hold said shaft structure in place, such that said shaft structure is substantially within said separate internal compartment and wherein said shaft comprises a sharp portion configured to puncture a portion of said housing and release internal device pressure in response to activation of said pyrotechnic features.

• internal components, said internal components comprising:
• fixed contacts electrically isolated from one another, said fixed contacts at least partially surrounded by said housing;
• one or more moveable contacts, said one or more moveable contacts allowing current flow between said fixed contacts when said one or more moveable contacts are contacting said fixed contacts;
• a shaft structure having a first end and opposite second end, said shaft structure connected at said first end to said one or more moveable contacts;
• a plunger structure connected to said shaft structure;
• contact structures electrically connected to said internal components for connection to external circuitry;
• and
• a solenoid configured to control movement of said plunger structure;
• and
• pyrotechnic features closer to said first end than said second end and configured such that when a threshold current level passes through said internal components, said pyrotechnic features activate and interact with said shaft structure, such that said shaft structure changes configuration, such that said moveable contacts separate from said fixed contacts.
