具体实施方式
下面参照附图详细地说明本公开的具体实施方式。
如图1～8所示，本公开的自复式过欠压保护器，包括底座10、主控制基板30和多个安装在所述底座10中的继电器20，所述继电器20的顶部设有信号引脚21，多个所述继电器20的信号引脚21通过导电体40连接；所述主控制基板30设置在所述继电器20的上方，所述继电器20的信号引脚21延伸至所述主控制基板30与所述主控制基板30连接。
信号引脚21设置在所述继电器20的顶部，直接与所述主控制基板30通过焊锡连接，省去了信号线，节约成本，而且使得产品的结构变简单，连接更可靠。信号引脚21通过导电体40被并联地连接，信号引脚21与导电体40通过焊锡连接，焊接后可目视焊点质量，解决半脱焊，提高产品安全性。
所述导电体40为铜片，也可以是铝、铁等其他导电体，实现各继电器20的信号引脚21的并联连接。
