Description

一种具有指示屏的空气开关 技术领域
本实用新型涉及继电器技术领域，尤其是涉及一种具有指示屏的空气开关。
背景技术
空气开关又名小型断路器、微型断路器，在电路中起着过载(过流)、短路保护等作用，即在过载或短路时自动断开电路。当然也可当作“开关”使用，因其灭弧介质为空气，所以称“空气开关”。空气开关的主触点是靠手动操作或电动合闸的，通常采用电磁扣，当电流过大或者短路时，电磁扣通电产生电磁，进而吸引主梁上的铁质部件，从而使主梁转动，进而断开电路；主梁旋转的同时，会带动拨动手柄由开变为关，显然的，当空气开关运行时，室内处于断电状态，往往需要使用者在黑暗中去摸索空气开关打开，容易产生安全隐患，又或者一排空气开关需要处理其中一部分时候，均会遇到使用不便的现象。
实用新型内容
本实用新型的目的在于提供一种具有指示屏的空气开关。
为实现上述目的，本实用新型采用以下内容：
一种具有指示屏的空气开关，包括：壳体、拨动手柄、连杆、主梁、电路组件和电磁扣，所述壳体的内部后侧设置有电路组件，且所述电路组件向所述壳体的上下两端伸出有连接端；所述电磁扣连接于所述电路组件；所述拨动手柄设置于所述壳体的前侧，并通过所述连 杆连接于所述主梁的一端；所述主梁纵向设置于所述壳体内部，且另一端抵接于所述电磁扣的底部，当电磁扣运行时，所述主梁推动拨动手柄开合，其特征在于，所述壳体的上部设置有指示屏，且所述指示屏穿过壳体连接于所述电磁扣，使得当电磁扣通电时，同时给指示屏供电。
优选的是，所述指示屏包括：标号牌、背景灯、针脚和框架；所述框架的内侧设置有背景灯，并固设于所述壳体上；所述标号牌嵌合于所述框架上；所述针脚的两端分别连接于所述背景灯和所述电磁扣，当电磁扣通电运行时，向背景灯供电。
优选的是，所述标号牌上设置有数字，并对应于空气开关的数量。
优选的是，所述背景灯为发光二极管，且数量为四个，均匀设置于所述框架的内侧。
优选的是，所述框架呈圆形，且所述背景灯分别位于所述框架的两垂直直径的端点处。
优选的是，所述壳体的侧面呈凸字形，且壳体的前端开设有用于所述拨动手柄开合的矩形开口。
本实用新型具有以下优点：
1、本申请通过利用了现有空气开关，对其附加了一种指示屏，能够清楚标记各个空气开关对应的房间或者电路，避免了使用者无法识别和寻找不变的困难。
2、本申请中的指示屏连接了空气开关内部的电磁扣，而电磁扣只有空气开关工作时才会通电具有磁力，因此能够及时的使指示屏亮 起。
附图说明
下面结合附图对本实用新型的具体实施方式作进一步详细的说明。

具体实施方式
为了更清楚地说明本实用新型，下面结合优选实施例对本实用新型做进一步的说明。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本实用新型的保护范围。
在本实用新型的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
在本实用新型的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“设置”应做广义理解，例如， 可以是固定相连、设置，也可以是可拆卸连接、设置，或一体地连接、设置。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至2所示，一种具有指示屏的空气开关包括：壳体1、拨动手柄2、连杆3、主梁4、电路组件5和电磁扣6，所述壳体1的内部后侧设置有电路组件5，且所述电路组件5向所述壳体1的上下两端伸出有连接端；所述电磁扣6连接于所述电路组件5；所述拨动手柄2设置于所述壳体1的前侧，并通过所述连杆3连接于所述主梁4的一端；所述主梁4纵向设置于所述壳体1内部，且另一端抵接于所述电磁扣6的底部，当电磁扣6运行时，所述主梁4推动拨动手柄2开合。所述壳体1的侧面呈凸字形，且壳体1的前端开设有用于所述拨动手柄2开合的矩形开口。
需要说明的是，电路组件包括上接线端、静触点片、静触点、灭弧电极、动触电杆、灭弧室、连接铜片和下接线端。其中，当主梁运动时，会将动触电杆与连接铜片断开，继而使室内整个线路断开。本申请对上述电路组件、主梁、电磁扣、连杆、拨动手柄的工作原理和方式并未作出改进，即上述的技术特征为现有技术特征，各种的空气开关基本都离不开上述部件，并且工作方式大同小异。
进一步地，所述壳体1的上部设置有指示屏7，且所述指示屏7穿过壳体1连接于所述电磁扣6，使得当电磁扣6通电时，同时给指示屏7供电。
需要说明的是，空气开关断电并不意味着空气开关内部是完全没 有电的，只是空气开关的下接线端与上接线端断路，而其中连接外部的接线端是仍然具有电流的，本申请中的指示屏连接于空气开关中电磁扣，即空气开关运行时，电磁扣仍然具有电流。
进一步地，所述指示屏7包括：标号牌701、背景灯702、针脚703和框架704；所述框架704的内侧设置有背景灯702，并固设于所述壳体1上；所述背景灯702为发光二极管，且数量为四个，均匀设置于所述框架704的内侧。
进一步地，所述标号牌701嵌合于所述框架704上；所述标号牌701上设置有数字，并对应于空气开关的数量。即框架上具有卡槽，标号牌能够直接卡合在卡槽内。其目的在于，能够增强适应性，将标号牌和空气开关对应起来。其中标号牌采用塑料材质。
进一步地，所述针脚703的两端分别连接于所述背景灯702和所述电磁扣6，当电磁扣6通电运行时，向背景灯702供电。针脚703连接所有的背景灯702，其材质为铜条，另一端通过镀锡连接电磁扣上。当电磁扣通电时，通过针脚给背景灯供电。
进一步地，所述框架704呈圆形，且所述背景灯702分别位于所述框架704的两垂直直径的端点处。显然的，圆形的框架是本申请中所做出的择优选择，但并不局限于圆形，技术人员完全可以将其根据合适空间进行布局，在此应做广义的理解。
本申请的工作原理：
空气开关在日常时间内，处于通路状态，当发生短路等现象，电流增大，电磁扣通电产生磁力，使主梁运行，断开电路，此时，电路 断开，但电磁扣上仍具有电流，指示屏上的背景灯由电磁扣上的电流供电。
显然，本实用新型的上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本实用新型的技术方案所引伸出的显而易见的变化或变动仍处于本实用新型的保护范围之列。
