ABSTRACT:
A hermetic terminal for carrying electric current into the housing of a hermetic compressor, including a metallic body member formed with three collar portions that define apertures through which respective fusible terminal pin assemblies extend. Each terminal pin assembly includes two electrically conducting pin segments interconnected by an electrically insulating sleeve member having opposite open ends into which respective ends of each pin segment are telescopingly received. The sleeve member and pin segments define a closed cavity in which a cylindrical fusible link is disposed. Opposite ends of the fusible link are received within respective counterbores in axial ends of the pin segments within the closed cavity, and are retained therein by a brazed joint. Each pin assembly is sealingly retained within a respective collar portion of the terminal body by a glass seal, which contacts the insulating sleeve and optionally surrounds one of the joints between the insulating sleeve and the pin segments.
