ABSTRACT:
In various embodiments of improvements in a hermetic refrigeration terminal of the type shown and described in U.S. Pat. No. 4,296,275, the flange of the current conducting pin is made non-circular, the pin is necked with a circumferential groove or, in the area in which it passes through the seal, is enlarged, or both, and, when a plurality of openings is provided in the bottom wall of the cup-shaped body of the terminal, a corresponding number of insulating sleeves are joined by a common web or spider, which may be provided with a zone of weakness or may be made flexible as compared with a rigid ceramic web, for example. In still other embodiments, a pin is made up of a core structure of copper or other highly electrically conductive material and a tube, of steel or other material compatible with the seal material, that extends through the reach of the seal, the tube being hermetically secured to the core structure. The flange is either provided on the core structure itself or on the tube.
