pin extending through it either before or after trimming or grinding the cathode feedthrough exterior pin end to be relatively flush with the exterior case wall. In this embodiment, the cathode connection terminal overlies the weld area on the exterior of the case wall. The exposed wire end of the cathode wire of the connector assembly is flush welded to the exterior of the case wall at the cathode connection terminal.
In further embodiments, the cathode terminal passageway comprises a location or section of the side wall upper opening edge having a width and depth depressed below the upper opening edge and a cover edge portion. The second cathode terminal end is trapped between the upper opening edge and the cover. The exposed wire end of the cathode wireof the connector assembly is flush welded to the exterior of the case wall at a defined cathode connection terminal.
In a first variation, the cathode terminal comprises a cathode tab extension foil of conductive material having a foil length extending between a first cathode terminal end thereof coupled with the plurality of cathode tabs and a second cathode terminal end thereof extending across the side wall upper edge opening. The second cathode terminal end of the cathode tab extension foil has a foil end width equal to or less than the step width and a foil end thickness about equal to the step depth. The second cathode terminal end extends across the side wall upper opening edge and is trapped therein by the cover hermetically sealed against the
