Terminal seal electrochemical device

Abstract

Abstract AN ELECTROCHEMICAL DEVICE HAVING A RESILIENT, ELECTROLYTE RESISTANT INNER LINING AND TOP (E.G. OF PLASTIC) AND CONNECTIONS BETWEEN THE ELECTRODES OF THE DEVICE THROUGH THE INNER TOP TO THE DEVICE TERMINALS WHICH ARE SEALED BY A COMPRESSION FIT BETWEEN THE TERMINAL CONNECTING POST AND RESILIENT INNER TOP. A HOLE OR PORT IN THE RESILIENT MEMBER AT THE POINT OF CONNECTION CARRIES THE TERMINAL CONNECTING POST WHICH CONSIST OF A HOLLOWED-OUT DEFORMABLE ELECTRICAL CONDUCTOR (E.G. OF LEAD). THIS DEFORMABLE POST IS MADE TO EXPAND AGAINST THE PLASTIC LINING TO FORM A LIQUID SEAL COMPRESSION FIT. THE EXPANSION MAY BE PROVIDED, INTER ALIA, BY AN EXTERNALLY EXPANDED RIVET OR BY THE ACTION OF A SELF TAPPING SCREW. THIS SEAL HAS PARTICULAR UTILITY IN SEALED OR RESEALABLY SAFETY VALVED BATTERY AND OTHER ELECTROLYTIC CELLS.
