    • A safety device for a battery which can prevent explosion of the battery due to overcharging or shortcircuiting. In the safety device, a current flows through generating unit, lead, terminal of a conductor case, PTC plate, annular terminal, contact to electrode lid. A disk spring, generally called a bimetal, is adapted to bend backward when it is heated to a predetermined temperature. If the generating unit heats up by producing gas due to overcharging or shortcircuiting, the disk spring is heated. When heated to a predetermined temperature, it will bend backward, while pushing up a moving piece, which in turn pushing up the contact, thus separating the contact from the annular terminal. The current-flow path in the battery is thus cut, so that the generating unit will not heat up any further.
    • 一种用于电池的安全装置,其可以防止由于过充电或短路引起的电池爆炸。 在安全装置中,电流流经发电机组,引线端子,导体壳体,PTC板,环形端子,与电极盖接触。 通常称为双金属片的盘弹簧适于当其被加热到预定温度时向后弯曲。 如果发电机由于过充电或短路而产生气体而加热,则盘簧被加热。 当加热到预定温度时,它将向后弯曲,同时向上推动移动件,而移动件反过来推动接触件,从而将接触件与环形端子分离。 因此,电池中的电流流动路径被切断,使得发电单元不会进一步升温。
