Description
技术领域technical field

背景技术Background technique
目前电动摩托车（电摩）行业普遍已采用60V（伏特）或72V电压的电池组，充电接口端子是直接连接到电池组的正负两极上的，外部电源通过充电接口端子对电池组充电。充电接口裸露铜接头两端带电在70-80V然而现有充电接口端子仅采用普通塑料盖片进行简单防护，裸露铜接头极易因异物或者金属物体触碰产生短路及触电现象无安全性可言。这种简单防护盖板式的结构并没有从根本上解决充电接口端子带有高压的问题。特别是当缺乏防护意识的用户或儿童无意中触碰到充电接口端子的正负极端而极易导致意外触电情况的发生。因此行业内急需一种对充电接口端子的有效安全隔离装置。以保障电动车充电接口裸露铜接头不带电（零电压）保证绝对的安全性。At present, the electric motorcycle (electric motorcycle) industry has generally adopted a battery pack with a voltage of 60V (volts) or 72V. The charging interface terminal is directly connected to the positive and negative poles of the battery pack, and the external power supply charges the battery pack through the charging interface terminal. The two ends of the exposed copper connector of the charging interface are charged at 70-80V. However, the existing charging interface terminals only use ordinary plastic covers for simple protection. The exposed copper connector is very easy to cause short circuits and electric shocks due to foreign objects or metal objects. There is no safety at all. . This simple protective cover structure does not fundamentally solve the problem of high voltage on the charging interface terminals. Especially when users or children who lack protection awareness inadvertently touch the positive and negative terminals of the charging interface terminals, it is very easy to cause accidental electric shock. Therefore, an effective safety isolation device for charging interface terminals is urgently needed in the industry. To ensure that the exposed copper connector of the electric vehicle charging interface is not charged (zero voltage) to ensure absolute safety.
