A SAFEGUARD APPARATUS PREVENTING OVERCHARGE FOR A SECONDARY BATTERY

摘要

The present invention relates to a safeguard apparatus preventing overcharge for a secondary battery. The safeguard apparatus preventing overcharge for a secondary battery that is comprised of a plurality of cells 10 which are arranged at regular intervals and respectively comprise a cathode 1, an anode 2 and electrolyte 3, wherein the secondary battery is comprised of a connection part 20 which is formed of a conductive material and disposed at an upper side of each cell 10; and a cut-off unit 200 which is formed of a conductive material and contacted with or separated from the connection unit 20 so as to switch on/off electric connection of the cells 10, is characterised to have a mechanical operating mechanism and is provided between the adjacent cells 10 of the secondary battery so as to convert horizontal force generated by change in volume of each cell 10 into vertical force.
