  • Glass-to-metal seal terminal pin for an electrochemical cell
    Patent number: 11670816
    Abstract: A lid assembly for an electrochemical cell comprises a plate-shaped lid having an opening and a glass-to-metal seal (GTMS) residing in the lid opening. The GTMS does not have a ferrule. Instead, the GTMS has a sealing glass that seals directly to a terminal pin and to the lid. The terminal pin has an enlarged diameter pin section contacted by the sealing glass and a first reduced diameter pin section extending axially outwardly from the enlarged diameter pin section. An electrochemical cell provided with the lid assembly is also described.
    Type: Grant

  • Novel Method For Gold Plated Termination of Hermetic Device
    Publication number: 20150004478
    Abstract: An electrochemical cell comprising a hermetic glass-to-metal seal utilizing a gold coated terminal lead is described. The surface of the terminal lead is directly coated with a layer of gold utilizing an electroplating method. The improved process improves manufacturing efficiencies and reliability of the electrochemical cell.

  • Laser beam button weld of dissimilar materials
    Patent number: 8648255
    Abstract: Terminal pins that include a refractory metal partially welded to a terminal block of a dissimilar metal incorporated into feedthrough filter capacitor assemblies are discussed. The feedthrough filter capacitor assemblies are particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.

  • Mismatched compression glass-to-metal seal
    Patent number: 6759163
    Abstract: A reverse mismatched compression glass-to-metal seal is described. In this seal, the coefficient of thermal expansion of the insulating glass is lower than that of the terminal lead and, the ferrule or casing body has a similar or higher coefficient of thermal expansion than that of the terminal lead.
