Igniter and method of making
View Patent ↗An igniter includes, a sleeve receptive to combustible medium, a resistor in operable communication with the combustible medium, and at least one lead in electrical communication with the resistor and the sleeve the electrical communication with the sleeve is maintained by interference fit between the sleeve and the at least one lead.
1. An igniter comprising:
a sleeve receptive to combustible medium;
a resistor in operable communication with the combustible medium;
a first lead in electrical communication with the resistor and the sleeve the electrical communication with the sleeve being maintained by a first interference fit between the sleeve and the first lead;
a conductor being in electrical communication with the resistor and a second lead, the electrical communication with the conductor and the second lead being by a second interference fit between the conductor and the second lead; and
a head in operable communication with the conductor, the conductor being structurally retained to the head via a flaring of a portion of the conductor, the flaring portion being in electrical communication with the conductor.
2. The igniter of claim 1 , wherein the first interference fit includes a crimp.
3. The igniter of claim 1 , further comprising a plate maintained in contact with the first lead and the sleeve by the first interference fit.
4. The igniter of claim 3 , wherein the plate includes a slot receptive to the first lead.
5. The igniter of claim 3 , wherein the plate is a disc.
6. The igniter of claim 3 , wherein the plate seals to at least one of the sleeve and the first lead to prevent the combustible medium from escaping therebetween.
7. The igniter of claim 1 , wherein the portion of the conductor that is flared has a tubular shape prior to being flared.
8. The igniter of claim 1 , wherein the second interference fit between the conductor and the second lead is a crimp between the conductor and the second lead.
9. The igniter of claim 1 , wherein the portion of the conductor that is flared has a frustoconical shape after being flared.
10. The igniter of claim 1 , wherein the conductor and the head are electrically isolated from one another.
11. The igniter of claim 1 , wherein the head is structurally attached to the sleeve by a third interference fit.
12. The igniter of claim 11 , wherein the third interference fit between the head and the sleeve is via a crimp between the sleeve and the head.
