Cell circuit interrupter

Patent ·
OSTI ID:6055526

A galvanic cell is described which consists of a metal container closed at one end and including in the container a positive electrode, a negative electrode and an electrolyte with the container being in electrical contact with one of the electrodes; a cover mounted over the metal container, the cover is secured to the metal container with at least a portion of the cover being electrically insulated from the container and in electrical contact with the other electrode; a conductive member. The conductive member is secured to a portion of the bottom of the container with an electrically insulating securing means so that at least a portion of the interial area of the conductive member is electrically insulated from the container while at least a portion of the peripheral area of the conductive member is in electrical contact with the bottom of the container; and wherein electrically conductive securing means secures the peripheral area of the conductive member to, and in electrical contact with, the bottom of the container so that when the center of the bottom of the container bulges a predetermined amount, the electrically conductive securing means will break to separate the peripheral area of the conductive member from the bottom of the container thereby breaking the electrical contact between the bottom of the container and the conductive member.
