Description

两极插座互锁保护门 技术领域
本发明涉及插座领域，特别是一种应用于两极插座的能够实现互锁的保护门。
背景技术
为了提高插座使用的安全性，避免由于误操作或小孩不懂而发生触电的意外事故，多在两极插座插孔下方、插套上方设置保护门，工作时，两电极插头插入插孔，使保护门打开，并同其下方的插套接合，完成正常的电连接。
中国专利文献CN2373908公开一种掀开式插座保护门，其采用翻盖式原理，对其内的插套形成遮盖阻挡来防止触电，但其不能完全防止单极插入造成的触电。
中国专利文献CN2497446公开一种两极插座保护门组件，当单极插入时，保护门使其不能接触插套，可防止单极插入时形成的触电，但其结构复杂，可靠性低，国标GB2099.1-2008中对插座保护门的要求有二：
（1）3×1mm的探针施加20N的推力及φ1mm的探针施加1N的推力均不可触及带电部件；
（2）为防单极插入而设计的保护门应能承受大于75N的单插销插入力。上述保护门结构仍存在着插入力过大造成触电的危险。
 发明内容
本发明的目的是提供一种新型的两极插座互锁保护门，可形成两极互锁保护，并且具有更好的防单销插入能力。
本发明的目的是通过以下技术方案来实现：
一种两极插座互锁保护门，安装于插孔及插套之间，由相互套合在一起且能够相对滑动的第一滑块和第二滑块组成；第一滑块对应第一插孔具有第一楔块和第一门板；第二滑块对应第二插孔具有第二楔块和第二门板；所述第一门板位于第二楔块下方，所述第二门板位于第一楔块下方；所述第一滑块和第二滑块后端均设有弹性部件。
优选的，所述弹性部件为弹簧。
本发明所述的保护门，对应每个插孔，由楔块和门板构成上下层叠的双层保护门结构，平时靠弹簧弹力使保护门关闭；单销插入时，可以依靠楔面推开楔块，打开上层保护门，位于其下面的门板构成下层保护门，受另一插孔下楔块控制而没有打开，因此单销不能插入插座取电；当二个插销同时插入时，上下层保护门同时打开，可以轻松地正常插入插套，完成正常的电连接；插头拨出时，保护门重新复位关闭。本保护门结构简单，具有互锁功能，单销插入时，门板运动受另一插孔下楔块控制而不能打开，使之具有更强的防单销插入能力。
 附图说明
下面根据附图和实施例对本发明作进一步详细说明。
图1是采用本发明所述两极插座互锁保护门的两极插座的正视图；
图2是图1所示插座去除面板后的内部结构图；
图3是图2的后视图；
图4是第一滑块和第二滑块装配结构图；
图5是第一滑块的部件图；
图6是第二滑块的部件图；
图7是第一滑块和第二滑块动作原理示意图。
图中：
1、第一滑块；11、第一楔块；12、第一门板；13、弹簧；2、第二滑块；21、第二楔块；22、第二门板；23、弹簧；3、插座面板。
 具体实施方式
如图1-6所示，给出本发明所述两极插座互锁保护门的组成结构示意图，其安装于插座面板3的插孔及插套之间，由相互套合在一起且能够相对滑动的第一滑块1和第二滑块2组成；第一滑块1对应第一插孔具有第一楔块11和第一门板12；第二滑块2对应第二插孔具有第二楔块21和第二门板22；其中第一门板12位于第二楔块21下方，第二门板22位于第一楔块11下方；对于任一个滑块，当插头插入时，可以依靠楔面推动楔块，从而使整个滑块沿垂直于插入方向动作，第一滑块1和第二滑块2后端分别设有弹簧13和弹簧23，可使滑块在插头拔出时恢复至原位。
参照图7，该两极插座互锁保护门的作用原理如下：对应每个插孔，由楔块和门板构成上下层叠的双层保护门结构，平时靠弹簧弹力使保护门关闭；单销插入时，可以依靠楔面推开楔块，打开上层保护门，位于其下面的门板构成下层保护门，受另一插孔下楔块控制而没有打开，因此单销不能插入插座取电；当二个插销同时插入时，上下层保护门同时打开，可以轻松地正常插入插套，完成正常的电连接；插头拨出时，保护门重新复位关闭。
本保护门结构简单，具有互锁功能，单销插入时，门板运动受另一插孔下楔块控制而不能打开，使之具有更强的防单销插入能力。
