Abstract
A hermetic structure includes a hermetic body having a through-hole passing through a high pressure side and a low pressure side, the through-hole having a tapered portion whose diameter increases from the low pressure side toward the high pressure side, a conductor inserted through the through-hole, a protector component fit in the tapered portion, the protector component having a hole for inserting the conductor, and a glass member provided in the through-hole, on the low pressure side from the protector component, so as to seal the conductor.
Claims6
A hermetic structure comprising:
- a hermetic body having a through-hole passing through a high pressure side and a low pressure side, the through-hole having a tapered portion whose diameter increases from the low pressure side toward the high pressure side;
- a conductor inserted through the through-hole;
- a protector component fit in the tapered portion, the protector component having a hole for inserting the conductor;
- and
- a glass member provided in the through-hole, on the low pressure side from the protector component, so as to seal the conductor.
A method of manufacturing a hermetic structure including a hermetic body having a through-hole, which passes through the high pressure side and the low pressure side and has a tapered portion whose diameter increases from the low pressure side toward the high pressure side, and a conductor inserted through the through-hole, comprising:
- fitting a protector component having a hole for inserting the conductor, in the tapered portion;
- and
- melting a glass member disposed on the low pressure side of the through-hole, in a state where the conductor is inserted through the hole, thereby sealing the conductor.
