其中，地线插脚5和地线弹片11分别设置有两个静触点51和两个动触点111，两个静触点51与两个动触点111一一对应，且相互配合接触。这样，当地线的其中一个动触点111或一个静触点51氧化或者表面粘上灰尘上使之接触不良时，可以通过另一个动触点111与静触点51接触，而且两个静触点51与两个动触点111的配合接触，能够提高地线的负荷能力，能够应对高负荷状况，使地线不影响通电，从而增强了安全性能，避免了引发使用人员触电和引发火灾等安全隐患。
上述的按键结构包括防水按键垫12、防水按键压板13和复位键14，所述防水按键垫12包括与复位键14配合的复位键套15、试验开关按键16和工作状态指示灯套17；所述复位键14和防水按键压板13配合连接；所述复位键14与横档8连接。防水按键垫12上的复位键套15、试验开关按键16和工作状态指示灯套17为一次成型橡胶或者硅胶。
进一步的，还包括试验键接触片18，所述试验键接触片18位于防水按键压板13和所述试验开关按键16之间。
进一步的，所述防水插脚底座19下端设有防水垫20，所述防水垫20位于防水插脚底座19和壳体1之间，以防止防水插脚底座19和壳体1之间进水。
所述壳体1设有与所述复位键套15、试验开关按键16和工作状态指示灯套17配合的通孔，线路板6上安装有工作指示灯，防水按键垫12与通孔处紧密贴合，防止水汽等从通孔进入壳体1内部。
所述壳体1还设有转换防水按键21，用于密封线路板6上转换按键部位，防止从插脚处进水。
所述线路板6上端还设有转换指示灯罩22，所述壳体1设有与转换指示灯罩22配合的透光孔。同样的，转换指示灯罩22起到密封作用，防止水汽从透光孔进入内部。
如图5-图8所示，所述防水插脚底座19的顶部设置有开口槽，分别为滑槽31和卡槽32，所述插脚压条7设置有三个引出端，所述插脚压条7从上往下地卡接在卡槽32内可引出端向下固定住零线插脚3、火线插脚4以及地线插脚5。所述横档8从上往下地安装在防水插 脚底座19上并可上下滑动，所述横档8设置有三个分别与零线弹片9、火线弹片10和地线弹片11对应的压紧端81。通过插脚压条7与防水插脚底座19之间卡接的方式来固定三个插脚，无需人工对其进行加固处理；固定方式非常方便。
具体的说，上述横档8中的其中一个压紧端81位于地线弹片11的顶部用于控制地线弹片11下移，所述地线弹片可自动向上位移。所述横档8的另外两个压紧端分别位于零线弹片9和火线弹片10的下端，所述零线弹片9和火线弹片10均可向下自动位移，即具有自动下移复位的功能。
具体的说，所述复位键14和横档8带有向上复位移动的功能。
如图9所示，本发明还包括互感器2，所述壳体1的内部设置有一个将互感器2从上往下插入到壳体内的插槽33，以适于自动化装配。
本发明工作原理如下：
如图2所示，正常状态下，零线弹片、火线弹片和地线弹片与其对应的插脚进行常闭连接；如图3所示，当按下复位键时，所述横档8的其中一个压紧端81带动地线弹片11下移从而使地线弹片11与地线插脚5两者之间的触点分离，同时另外两个压紧端81解除对火线弹片10和零线弹片9向下移动的压力，使火线弹片10和零线弹片9的触点下移从而与火线插脚4和零线插脚3的触点分离，即实现断电。当复位键14向上复位后，所述横档8带动压紧端上移，可带动零线弹片9、火线弹片10和地线弹片11上移并分别与零线插脚3、火线插脚4以及地线插脚5接触而通电。
本发明的漏电保护器，与传统的漏电保护器相比，改变了原来对漏电保护器横档进行穿孔等设计，使漏电保护器整体形成了一个叠放的结构，因此使装配设备可采用叠放的装配方式装配，实现了为了适于自动化装配。通过卡接的方式使联动机构和线路板进行固定，无需人工对其进行加固处理；地线断开机构，采用横档位移的方式对地线进行断开动作，同时，横档延伸端对零火线进行断开动作，整个断开机构实现了零火地线同时通断的功能，同时增加了多处防水结构，大大提高了防水效果；而且，当地线的其中一个动触点或一个静触点氧化或者表面粘上灰尘上使之接触不良时，可以通过另一个动触点与静触点接触，并能够有效应对高负荷，使得地线不影响通电，从而增强了安全性能，避免了引发使用人员触电和引发火灾等安全隐患。
实施例二：本实施例的结构、操作过程与实施例一基本相同，实现的功能都相同，所不同的是所述横档8的另外两个压紧端分别位于零线弹片9和火线弹片10的上端，所述零线弹片9和火线弹片10均具可向上自动位移，即具有自动上移复位的功能。
其具体的操作如果如下：当按下复位键时，所述横档8的3个压紧端81带动零线弹片9、火线弹片10和地线弹片11的位置均下移，从而使上述弹片的触点和上述插脚的触点分离而实现断电。当复位键14向上复位后，横档8的3个压紧端81上移以解除对3个弹片向上移动的压力，从而使3个弹片通过自身的自动向上复位功能与上述3个插脚的触点接触而通电。
当然本发明有可以有其他的实施例，比如可以将3个压紧端81与3个弹片直接连接以控制3个弹片上下移动。
综上所述，上述实施方式并非是本发明的限制性实施方式，凡本领域的技术人员在本发明的实质内容的基础上所进行的修饰或者等效变形，均在本发明的技术范畴。
