Abstract
An electrical igniter for incendiary and explosive devices. In particular, an electrical igniter assembly comprising two component parts including a cap and well where an ignition or detonation mixture may then be positioned within the well along with electrical leads.
Claims17
An igniter assembly for incendiary or explosive devices comprising:
- a. an igniter cap configured to mechanically engage with an igniter body well portion, said igniter cap including one or a plurality of openings for one or a plurality of electrical wire connection leads and an interior hollow projection that is configured to project into at least a portion of said igniter body well portion;
- b. an igniter body well portion that is configured to mechanically engage with said igniter cap and to receive said igniter cap hollow projection;
- wherein said igniter cap with said interior hollow projection, when engaged to said igniter body well portion, defines a variable volume chamber to contain a selected amount of ignition or detonation compositions.
A method for providing an incendiary or explosive device for detonation comprising:
- a. supplying an igniter cap configured to mechanically engage with an igniter body well portion, said igniter cap including one or a plurality of openings for one or a plurality of electrical wire connection leads and an interior hollow projection that is configured to project into at least a portion of said igniter body well portion;
- b. supplying an igniter body well portion that is configured to mechanically engage with said igniter cap and to receive said igniter cap hollow projection wherein said igniter cap with said interior hollow projection, when engaged to said igniter body well portion, defines a variable volume chamber to contain a selected amount of ignition or detonation compositions;
- c. supplying said one or plurality of electrical connection leads and placing said one or plurality of electrical connection leads in said opening in said igniter cap and through said interior hollow projection and into said variable volume chamber, d. connecting said electrical connection leads in said variable volume chamber to an igniter squib;
- e. placing a selected amount of ignition or detonation composition into said variable volume chamber;
- f. mechanically engaging said igniter cap and said igniter well portion with an incendiary or explosive device.
