HIGH-VOLTAGE AIRTIGHT TERMINAL AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is a high-voltage airtight terminal (10) comprised of an eyelet (15) having a through-hole (14); and a lead (30) which is electrically insulated via a glass element (20) and hermetically sealed in the through-hole (14), wherein the glass element (20) is welded so as to extend from the end portion of the through-hole (14) to the surrounding area of the through-hole (14) in the lower surface of the eyelet (15). The eyelet (15) has a spot-faced portion (40) in the surrounding area of the through-hole (14), in the lower surface of the eyelet (15). It is preferable that the glass element (20) is welded to the inside of the spot-faced portion.
