Description

一种可同时关断零线和相线的磁保持继电器 【技术领域】
本发明属于继电器设备技术领域，具体涉及一种可同时关断零线和相线的磁保持继电器。
【背景技术】
由于科技的进步，普通计量电表逐渐被智能化的电表代替，从而实现远程控制、远程收费等功能。磁保持继电器在这一领域得到了广范的应用。但在实际的使用中，普通单回路磁保持继电器仅能切断其中一路相线，也就是说住户家中的电路始终有一路是和外部供电回路相连。这给雷电、或错接线路把强电引入住户家中提供了可能，对人和房屋带来安全隐患。为解决上述问题，目前许多生产厂商采用两只单路磁保持继器组合的方案，在实际使用中起到了完全隔离的功能。但这种方式在成本上有所增加，且电表内部空间本来就很小，加上两只继电器后空间显得尤为不足，且不利于散热，难于推广等。
【发明内容】
本发明的目的在于提供一种可同时关断零线和相线的磁保持继电器，以解决目前磁保持继电器体积大，成本高等问题。
为解决以上技术问题，本发明采用以下技术方案：
一种可同时关断零线和相线的磁保持继电器，包括：壳体，设置于壳体内的两组控制回路和磁路系统；
两组控制回路，每一组所述控制回路由一动簧座和一静簧座组成，其中一组控制回路的静簧座连接第一引脚，该组控制回路的动簧座连接第四引脚；另一组控制回路的静簧座连接第二引脚，该组控制回路的动簧座连接第三引脚；所述连接第一引脚的静簧座加长并折弯；所述动簧座由一组相线控制，所述静簧座由一组零线控制，该组相线和零线组成一个可以同时关断相线和零线的回路；
所述磁路系统设置于所述连接第一引脚的静簧座的折弯中间，所述磁路系统 与每一所述动簧座和静簧座垂直设置；所述磁路系统通过一个推动片的推动力同时推动每一组所述控制回路中的动簧座，以同时控制每一组所述控制回路中所述动簧座的开合。
作为优选，所述连接第一引脚的静簧座自该控制回路的触点位置处开始折弯。
作为优选，所述连接第一引脚的静簧座包含两个折弯直角。
作为优选，所述磁路系统和所述连接第二引脚的静簧座以及连接第三引脚的动簧座位于所述连接第一引脚的静簧座的两个折弯直角内。
作为优选，所述连接第一引脚的静簧座采用分段连接加长。
作为优选，所述静簧座分段连接处采用铆接连接。
作为优选，所述静簧座分段连接处还可以采用焊接连接。
作为优选，所述第一引脚、第二引脚为输入端，所述第三引脚、第四引脚为输出端。
作为优选，所述磁路系统可提供普通单回磁路的2倍磁力。
作为优选，所述磁路系统一侧为连接第一引脚的静簧座，另一侧为连接第二引脚的静簧座、第三引脚的动簧座、第四引脚的动簧座。
与现有技术相比，本发明具有以下有益效果：
本发明提供了一种可同时关断零线和相线的磁保持继电器，与传统继电器相比，本发明的磁路系统设置于连接第一引脚的静簧座的折弯中间，使得继电器的整体体积减小，有利于降低生产成本。

图4是两个传统的单路磁保持组合继电器的结构尺寸图。
图中，1为第一引脚，2为第二引脚，3为第三引脚，4为第四引脚，5为推动片，6为磁路系统，7为壳体。
【具体实施方式】
下面结合具体实施方式并对照附图对本发明作进一步详细说明。应该强调的是，下述说明仅仅是示例性的，而不是为了限制本发明的范围及其应用。
如图1、图2所示，一种可同时关断零线和相线的磁保持继电器，包括：壳体7，设置于壳体7内的两组控制回路和磁路系统6；
两组控制回路，每一组所述控制回路由一动簧座和一静簧座组成，其中一组控制回路的静簧座连接第一引脚1，该组控制回路的动簧座连接第四引脚4；另一组控制回路的静簧座连接第二引脚2，该组控制回路的动簧座连接第三引脚3；所述第一引脚1、第二引脚2为输入端，所述第三引脚3、第四引脚4为输出端；所述连接第一引脚1的静簧座加长并折弯，且该静簧座自该控制回路的触点位置处开始折弯，总共包含两个折弯直角；同时，所述连接第一引脚1的静簧座采用分段连接加长，其在分段连接处采用铆接连接或焊接连接的方式连接加长；所述动簧座由一组相线控制，所述静簧座由一组零线控制，该组相线和零线组成一个可以同时关断相线和零线的回路。所述磁路系统6设置于所述连接第一引脚1的静簧座的折弯中间，所述磁路系统6与每一所述动簧座和静簧座垂直设置；所述磁路系统6一侧为连接第一引脚1的静簧座，另一侧为连接第二引脚2的静簧座、第三引脚3的动簧座、第四引脚4的动簧座；所述磁路系统6和所述连接第二引脚2的静簧座以及连接第三引脚3的动簧座位于所述连接第一引脚1的静簧座的两个折弯直角内。所述磁路系统6通过一个推动片5的推动力同时推动每一组所述控制回路中的动簧座，以同时控制每一组所述控制回路中所述动簧座的开合；所述磁路系统6可提供普通单回磁路的2倍磁力。
为验证本发明的有益效果，对比本发明与传统磁保持继电器的体积(因本发明为双回路继电器，对比例应为两个单路磁保持组合继电器)，如图3、图4所示，其结果如下。
项目类别 长(mm) 宽(mm)
本发明的继电器 70 59
对比例 85.3 65.3
因本发明与对比例的继电器厚度相当，故只需对比其长度和宽度；由上述表格数据可知，本发明的体积约为对比例的3/4，所以本发明的磁保持继电器体积小，成本低。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明，对于所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明由所提交的权利要求书确定的专利保护范围。
