Abstract
A 'ball and socket' seal arrangement for an electrochemical cell is disclosed wherein a ball of insulating material is captively retained in a socket formed by a portion of the cell cover in cooperation with a retaining member. The cell feedthrough passes through the socket and the insulating ball. After assembly of the components, the sockets are compressed, thereby forcing the insulator ball to conform to the inner surface of the socket to make an effective seal.
