HIGH PRESSURE PROOF IGNITION DEVICE AND ITS ASSEMBLY METHOD

摘要

PROBLEM TO BE SOLVED: To electrically explode a glass vs metal seal header by providing an integrated circuit means to ignite an ignition material on the glass vs metal seal header and airtightly enclosing the glass vs metal seal header in a shell casing. SOLUTION: A glass vs metal seal assembly body is formed by fixing a shell casing in the inside of a graphite plate and a socket pin in the shell casing. Glass is hardened and adhered closely to a metal surface at the time of getting out of a cooling chamber of a furnace, and airtight enclosure is formed between the socket pin and the glass and between the shell casing 10 and the glass. A loading holder 48 is installed on a glass vs metal seal header 40, and this loading holder 48 has an ignition material and a closing panel assembly body 44. A header pin 42 of the glass vs metal seal header 40 on which an integrated circuit 46 is installed is inserted into a socket, and the loading holder 48 is arranged by covering the header 40.
