摘要： Disclosed herein is a safety switch including a tube that is capable of shrinking when exposed to temperatures in excess of a predetermined temperature level (“heat shrinkage tube”), wherein the length of the heat shrinkage tube is changeable to control current conduction, one end of the heat shrinkage tube is fixed, and the other end of the heat shrinkage tube is connected to an electric wire connection part, such that current conduction or current interruption is accomplished by the change in length of the heat shrinkage tube when the heat shrinkage tube is varied due to heat. When a battery or a battery pack is exposed to an abnormal environment, with the result that the temperature of the battery or the battery pack exceeds a predetermined temperature level, the heat shrinkage tube of the safety switch shrinks to directly interrupt external charge current, thereby preventing the further charge of the battery or the battery pack. Furthermore, internal energy accumulated in the battery cell is forcibly consumed, thereby fundamentally preventing the progress of the abnormal operation of the battery or the battery pack. Consequently, the safety of the battery is secured.
摘要翻译：本文公开了一种安全开关，其包括当暴露于超过预定温度水平的温度（“热收缩管”）时能够收缩的管，其中，热收缩管的长度可改变以控制电流传导，一端热收缩管的另一端与电线连接部连接，通过热收缩管的长度变化来实现电流导通或电流中断由于热而变化。当电池或电池组暴露于异常环境时，电池或电池组的温度超过预定的温度水平，安全开关的热收缩管收缩以直接中断外部充电电流，从而防止电池或电池组进一步充电。此外，蓄积在电池单元中的内部能量被强制消耗，从而从根本上防止电池或电池组的异常运行的进行。因此，确保了电池的安全性。
