ABSTRACT:
A hermetic terminal comprising a metallic wall having at least one opening therein through which a conductor pin extends, said pin being secured in said opening by means of a glass-to-metal seal, said pin comprising three distinct sections, namely, a first section of any suitable electrically conductive material, such as cold rolled steel, a second intermediate section of a sealing alloy, such as stainless steel or a nickel-iron alloy, and a third section of a highly conductive, corrosion-resistant metal, such as copper. The intermediate section of the pin, i.e., the sealing alloy, contacts the glass in the aforesaid glass-to-metal seal with the copper section of the pin extending in one direction from the metallic wall and the cold rolled steel section of the pin extending in the opposite direction therefrom.
