Abstract
A terminal structure and seal for an electrochemical cell includes a terminal post inside a plastic tubular member which is inside a metal barrel. The plastic tubular member is unitary with the plastic cover and a reinforcing boss on the cover is annular and an annular stabilizing flange unitary with the metal barrel is embedded in this reinforcing boss. The metal barrel is separated from the interior of the electrochemical cell so that the metal barrel need not be resistant to the electrolyte and so that there is no potential leakage path between internal threads on the metal barrel and external threads on the plastic tubular member. The foregoing Abstract is merely a resume of general applications, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
