FIELD: electricity.
SUBSTANCE: method for sealing of accumulator terminal may be used in manufacturing of accumulators with high requirements to mechanical and climatic (temperature and atmospheric pressure) loads. Method consists in the fact that sealing of accumulator terminal includes installation of terminal with square flange and sealing ring into opening of accumulator cover, at that terminal flange is installed in square groove of cover, installation of bush with flange onto terminal and its pressing to accumulator cover, providing for compression of sealing ring and fixation of bush on terminal, i.e. rolling of bush cylindrical part into annular groove of terminal.
EFFECT: method makes it possible to provide for high strength and reliability of sealing unit for terminals and accumulator cover, prevents displacement of terminal both along axis and around it.
