Claims

[Claims for Utility Model Registration] (1) A capacitor having a through conductor inserted therein is built into the large cylindrical part of an external metal fitting formed in a stepped cylindrical shape having a large cylindrical part and a small cylindrical part, In the feed-through capacitor in which the large cylindrical part and the small cylindrical part are filled with an insulator, the large cylindrical part of the external fitting is inclined outwardly and expanded, and the large cylindrical part and the small cylindrical part are connected to each other. A through-type capacitor, characterized in that a metal fitting protruding toward the inner diameter side of the small cylindrical portion is connected and fixed to the stepped surface, and the capacitor is connected and fixed on the metal fitting. (2) The feedthrough capacitor according to claim 1, wherein the metal fitting has a washer shape with a center hole. (3) The capacitor has a disc shape with an outer diameter larger than the center hole diameter of the metal fitting and smaller than the inner diameter of the small cylinder part, as set forth in claim 2 of the utility model registration claim. Feedthrough capacitor. (4) The capacitor is registered as a utility model, characterized in that the diameter of the through hole through which the through conductor is passed is sufficiently larger than the outer diameter of the through conductor, and the gap between the two is filled with the insulating resin. A feedthrough capacitor according to claim 3. (5) The feed-through capacitor according to claim 3 or 4, wherein the feed-through conductor has a silicone tube covering at least in a portion passing through the center hole of the capacitor. . (6) The through conductor is characterized in that it has an external contact whose lower end is connected and fixed to the electrode of the capacitor, and an internal contact that is insulated and coaxially arranged in the center of the external contact. Scope of Utility Model Registration Claims Paragraph 1, Paragraph 2, Paragraph 3
5. The feedthrough capacitor according to item 4 or 5. (7) The feedthrough capacitor according to claim 6, wherein a lower end of the external contact is connected and fixed to an electrode of the capacitor.
