Filed:

May 13, 1982

Appl. No.:

6/377790

Inventors:

Hillel Kellerman - Los Angeles CA

Leonard J. Box - West Orange NJ

International Classification:

H01R 4300
C03C 2702

US Classification:

428 36

Abstract:

Glass-to-metal hermetic seal of the compression type in which a central metal eyelet is sealed to a central conductor, the eyelet being bondable to and having a coefficient of expansion characteristic compatible with glass in which the eyelet is made non-ferromagnetic to eliminate unwanted induction heating and losses in pulsatory current carrying operation. The method of forming the seal is disclosed.

International Classification:

H01G 114
H01G 700

US Classification:

361306

Abstract:

A hermetically sealed capacitor comprises a generally cylindrical ceramic tube having opposite annular tube ends that are generally parallel to each other; a generally cylindrical capacitor element within the tube; and a pair of metal end caps, each including a receptacle defined by a generally circular end wall portion, an integral tube wall portion, and an integral terminal. The inner diameter of the tube wall portion is slightly larger than the outer diameter of the ceramic tube portion so as to provide, during assembly of the capacitor, an aligning guide for disposing the ceramic tube end within the receptacle. A pair of parallel disk-shaped soldered bonds are provided; each bonding one of the end caps to one of the tube ends so that the ceramic case, the end caps, and the bonds provide a hermetically sealed case for the capacitor element.
