现有技术中的电器开关的指示部件仅有两种位置的指示，即“合”和“分”。即当正常工作时指示为“合”，而指示为正常断开和故障断开均指示为“分”。部分电器开关的指示部件可以指示故障状态，但都需要使用另外的故障指示部件。通过故障指示部件和原有的指示部件的组合显示来表示故障断开的状态。多个指示部件使得组合显示变得复杂，同时多个指示部件也使得机械结构更加复杂，不利于电器开关装置的小型化，也会使得制造成本增加。

在一个实施例中，指示部件包括：本体、轴、指示面板、第一支脚和第二支脚。本体呈弯折形，本体的第二端分叉形成第一臂和第二臂。轴位于本体的中部。指示面板安装在本体的第一端，指示面板上具有指示标记，指示面板的一端具有向两侧延伸的限位卡脚。第一支脚安装在本体的第二端的第一臂上。第二支脚安装在本体的第二端的第二臂上。
在一个实施例中，本体的第一臂和第二臂具有弹性。第一支脚与驱动零件配合。第二支脚与卡位零件配合。
在一个实施例中，卡位零件具有限位脚，限位脚与指示部件的第二支脚配合。
在一个实施例中，指示部件具有三个位置：正常接通位置、正常分断或者非短路故障分断位置、短路分断位置。卡位零件具有三个位置，卡位零件在三个位置之间转动。驱动零件具有两个位置，驱动零件在两个位置之间移动。
在一个实施例中，指示面板设置有三个指示标记：指示电器开关正常接通的指示标记、指示电器开关正常分断或者非短路故障分断的指示标记、指示电器开关短路分断的指示标记。
在一个实施例中，卡位零件具有位置A、位置B和位置C，位置C位于位置A和位置B之间，卡位零件位于位置C，驱动零件与第一支脚配合，限位脚与第二支脚配合，第一臂与第二臂产生形变，指示部件停留在短路分断位置。
本发明的电器开关的指示装置采用单个指示部件，但具有至少三个指示位置，通过指示部件自身的形变来提供第三个位置，实现了较为简单的结构和较低的制造成本。

具体实施方式
本发明提出一种电器开关的指示装置，该指示部件具有至少三个指示位置，每一个指示位置对应电器开关的一种状态，在每一个指示位置指示部件显示一种指示标记。在一个实施例中，指示部件具有三个指示位置，分别对应电器开关的三种状态：正常接通状态、正常分断或者非短路故障 分断状态、短路分断状态。
参考图1、图2和图3所示，揭示了根据本发明的一实施例的电器开关的指示装置的结构示意图，以及采用该指示部件的电器开关的面板结构的示意图。该电器开关的指示装置包括指示部件101、驱动零件103和卡位零件102。指示部件101转动安装在电器开关的壳体上，指示部件101对准电器开关的面板104上的指示孔141，指示部件101上具有数个指示标记。指示孔141的大小与指示部件101上的单个指示标记匹配，这样，从面板141的正面，通过指示孔141能够观察到指示部件101上的其中一个指示标记，并且每次只能观察到其中的一个指示标记。驱动零件103安装在电器开关的壳体内。如图1所示，驱动零件103布置在指示部件101的下方，需要说明的是，在实际的布置中，驱动零件103并不一定是布置在指示部件101的下方，但驱动零件103、指示部件101和卡位零件102之间的相对位置关系是如图1所示的关系。驱动零件103驱动指示部件101转动至一个指示位置，指示部件101上的其中一个指示标记对准指示孔141，以指示电器开关对应的一个状态。卡位零件102安装在电器开关的壳体内，在图示的实施例中，卡位零件102是安装在驱动手柄105的底部，驱动手柄105的手柄部分位于面板104之上，驱动手柄105的底部位于面板104以下。卡位零件102与指示部件101配合，使得指示部件101上指定的指示标记对准指示孔141，或者说，卡位零件102使得指示部件101被限制在指定的指示位置。卡位零件102上具有一个限位脚121，卡位零件102通过该限位脚121来限制指示部件101的位置。
下面具体描述该指示部件的工作过程。
参考图4所示，揭示了根据本发明的一实施例的电器开关的指示装置中指示部件的结构图。如图1所示，该指示部件101包括一本体116，本体116呈弯折形。本体116的中部具有轴114。本体116的第一端安装有指示面板115，指示面板115上具有指示标记。在图示的实施例中，指示面板115是一个弧形板，指示面板115上按照一定的间隔设置有三个指示 标记：指示电器开关正常接通的指示标记“1”、指示电器开关正常分断或者非短路故障分断的指示标记“0”、指示电器开关短路分断的指示标记“I>>”。指示面板115的一端具有向两侧延伸的限位卡脚113。本体116的第二端分叉形成第一臂和第二臂。第一臂上安装有第一支脚111，第二臂上安装有第二支脚112。在图示的实施例中，第一支脚111是圆柱形，第二支脚112是方柱形。第一臂和第二臂具有弹性，在受到外力时会产生形变。
参考图5a、图5b和图5c所示，驱动零件103在图示的Y方向上往复移动，驱动零件103推动指示部件101的第一支脚111，使得指示部件101以轴104为中心旋转。参考图1所示，驱动零件103上具有一个驱动平台131，该驱动平台131与第一支脚111接触以驱动第一支脚111。如图所示，驱动零件103在位置D和位置E之间移动，推动第一支脚111在位置G和位置F之间移动，对应指示部件101在第一位置和第二位置之间移动。由于第一支脚111的位置与指示部件101的位置是完全对应的，为了表述方便，下面就以位置G和位置F来一并代指第一支脚111和指示部件101的位置。第一支脚111带动指示部件101绕轴104转动。随着指示部件101的转动，弧形的指示面板115也随之移动，指示面板115上的不同位置会与指示孔141对准，使得不同的指示标记在指示孔141中显现，以指示电器开关的不同状态。驱动零件103从位置D向位置E移动时，会对第一支脚111施加力，带动指示部件101转动。驱动零件103从位置E向位置D移动时，驱动零件103不再对第一支脚111施加力。指示部件101的依靠其自身复位力从位置F回到位置G。指示部件101的自身复位力可以来自与弹簧、复位结构或者重力。
图6揭示了根据本发明的一实施例的电器开关的指示装置的俯视结构图。如图6所示，卡位零件102通过其限位脚121来限制指示部件101的位置。结合图7a、7b、7c、8a、8b和8c所示，卡位零件102可以停在三个位置：位置A、位置B和位置C。位置C位于位置A和位置B之间， 卡位零件102能在位置A和位置B之间转动。
电器开关正常接通时，各个零件的动作如下：卡位零件102在驱动手柄105的带动下由位置B转动到位置A，参考图7a所示。驱动零件103从位置E运动到位置D，驱动零件103不在对指示部件101施加力。指示部件101在自身复位力的作用下从位置F运动到位置G，第一支脚111也由位置F向位置G转动。指示部件101上的限位卡脚113由面板104上的限位件142(参考图3所示)限位，使得指示部件101停止在位置G。在位置G，指示电器开关正常接通的指示标记“1”与面板上的指示孔141对准。参考图8a所示，通过指示孔141观察到指示标记“1”，表示电器开关正常接通。
电器开关正常分断或者非短路故障分断时，各个零件的动作如下：卡位零件102在驱动手柄105的带动下由位置A转动到位置B，参考图7b所示。驱动零件103从位置D运动到位置E。驱动零件103对指示部件101的第一支脚111施加力，指示部件101在驱动零件103推动第一支脚111的作用下从位置G运动到位置F。指示部件101停止在位置F。在位置F，指示电器开关正常分断或者非短路故障分断的指示标记“0”与面板上的指示孔141对准。参考图8b所示，通过指示孔141观察到指示标记“0”，表示正常分断或者非短路故障分断。
在出现除短路以外的故障时，各个零件的动作顺序如下：先是电磁铁动作，然后是脱扣器动作。电磁铁动作带动驱动零件103从位置D运动到位置E，带动指示部件101从位置G运动到位置F。脱扣器动作使驱动手柄105带动卡位零件102的限位脚121运动到位置B。在位置B，限位脚121并不会对指示部件101的动作产生影响
电器开关出现短路故障而短路分断时，各个零件的动作如下：卡位零件102在驱动手柄105的带动下位置A转动到位置C，参考图7c所示。在位置C，卡位零件102的限位脚121会对指示部件101的第二支脚112进行限位。驱动零件103从位置D运动到位置E。驱动零件103对指示部 件101的第一支脚111施加力，指示部件101在驱动零件103推动第一支脚111的作用下从位置G向着位置F运动。在指示部件101的运动过程中，第二支脚112会被限位脚121所限制，因此指示部件101无法运动到位置F，而是停留在位置G和位置F中间的位置。驱动零件103从位置D运动至位置E并且停留在位置E。此时指示部件101的第一支脚111和第二支脚112分别受到挤压，由于第一臂和第二臂具有弹性，因此受到挤压后两个臂产生形变，如图9所示。但指示部件101停留在位置G和位置F中间的位置上。在这个中间位置，指示电器开关短路分断的指示标记“I>>”与面板上的指示孔141对准。参考图8c所示，通过指示孔141观察到指示标记“I>>”，表示短路分断。
本发明的电器开关的指示装置采用单个指示部件，但具有至少三个指示位置，通过指示部件自身的形变来提供第三个位置，实现了较为简单的结构和较低的制造成本。
上述实施例是提供给熟悉本领域内的人员来实现或使用本发明的，熟悉本领域的人员可在不脱离本发明的发明思想的情况下，对上述实施例做出种种修改或变化，因而本发明的保护范围并不被上述实施例所限，而应该是符合权利要求书提到的创新性特征的最大范围。
