Abstract
A modular initiator assembly comprising a receptacle and connector combination adapted to shunt the electrical contacts of the initiator as a default condition and to only unshunt the electrical contacts coupled to the initiator when the receptacle and connector establish a fully seated connection.
Claims20
A modular initiator connection comprising:
- a connector attached to an initiator;
- a first contact blade within the connector and electrically connected to a first resistor contact;
- a second contact blade within the connector and electrically connected to a second resistor contact;
- a first conductive shunt contact integral to the first contact blade within the connector forming an electrical shunt between the first contact blade and the second contact blade and having a curved surface facing away from the connector;
- a receptacle;
- a first signal contact within the receptacle and adapted to electrically connect to the first contact blade;
- a second signal contact within the receptacle and adapted to electrically connect to the second contact blade;
- a nonconductive separator within the receptacle between the first signal contact and the second signal contact adapted to mechanically and electrically separate the first shunt contact and the second blade contact when the receptacle is fully inserted into the connector by wedging the curved surface of the first conductive shunt away from the second contact blade;
- a latch adapted to lock the receptacle into the connector;
- wherein inserting the receptacle into the connector first electrically connects the first contact blade and second contact blade to the first signal contact and second signal contact respectively, second electrically separate the first shunt contact and the second blade contact with the nonconductive separator, and third engages the latch to lock the receptacle into the connector;
- and
- wherein the first resistor contact and second resistor contact provide electrical connection to the initiator.
