Description

一种微动开关、驱动器制造方法以及驱动器 技术领域
本申请涉及微动开关领域，具体涉及一种微动开关、驱动器制造方法以及驱动器。
 背景技术
微动开关是具有微小接点间隔的快动机构，用规定的行程和规定的力启动开关动作的接点机构，该接点结构一般由致动部，比如驱动杆，推动的一种开关，因其开关的触点间距比较小，故又称微动开关。
现有的微动开关，包括壳体，壳体内设置有常开触片、常闭触片和连接片，并分别从壳体内伸出形成常开端子、常闭端子和连接端子，动簧片用于连接该常开触片与常闭触片，其中，动簧片为电连接部件。 伸出壳体的常开端子、常闭端子以及连接端子用于连接电路器件以及电路连线。
 技术问题
现有的常开端子、常闭端子或者连接端子一般在端子末端开设封闭孔，通过封闭孔组装和焊接电路器件以及电路连线。但是，随着器件的小型化，小型微动开关连接端子的封闭孔连接结构已不便于微动开关与相关器件的连接和组装，特别是在自动化的组装设计中。
微动开关可以应用于驱动器上，驱动器主要用于将马达的旋转运动转变为推杆的直线运动或者直线往复运动的驱动装置。驱动器作为执行电动机械，可实现远距离控制、集中控制或自动控制。比如，驱动器应用于电动医疗床、电动椅、电动沙发等设备上用以驱动上述设备的可动部件上升或下降。
现有的线性驱动器控制线路中，通常在行程开关组件中设置两个确定线性运动行程的微动开关。微动开关可以整合在电路板上或者通过线材连接组装。在通过线材连接组装微动开关时，现有的微动开关，比如包括两片连接端子，每个连接端子上开设连接线材的封闭孔，并采用手动组装和焊接。在自动化产线上，设置封闭孔的微动开关使自动化设备的机械手抓取二极管后，需要将二极管倾斜以将其一管脚倾斜插入微动开关的单边封闭孔内，在平移二极管以将二极管的另一管脚插入微动开关的另一封闭孔中再释放二极管，由于微动开关的连接端子开设的封闭孔孔径非常小，如果用机械手以倾斜插入的方式组装，则机械手的工艺精密程度以及控制精度都要求非常高，增加驱动器的制作成本。
因此，在现有线性驱动器的行程开关组装中仅二极管的放置就需要机械手的两个动作才能将二极管插入微动开关，增加了驱动器制造的工艺过程以及时间。
因此，现有的微动开关以及相关驱动器制造工艺技术还有待于改进和发展。

在该微动开关组装槽的第一实施例中，该组装槽开设在该至少两个接触端子的末端，该组装槽的开口中心线与对应接触端子的中心线重合，使得该至少两个接触端子伸出该壳体的部分呈U型构造。

实施例1
请参考图1至图5，本实施例的微动开关，以驱动器的第一微动开关15为例进行详述。该开关包括壳体、致动部151、第一接触端子152、第二接触端子154、可动片159以及接触簧片158。
该壳体包括上壳体157与下壳体156，上壳体157与下壳体156扣合在一起中部形成安装腔体，该安装腔体内安装伸出该上壳体157的致动部151、伸出该下壳体的第一接触端子152以及第二接触端子154。该第一接触端子152以及第二接触端子154之间根据该致动部151的运动作可动片159以及接触簧片158建立电性连接，该伸出下壳体156的该第一接触端子152以及第二接触端子154均上开设非封闭式组装槽。
该可动片159连接该第一接触端子152，该接触簧片158连接该第二接触端子154，该可动片159与致动部151联动。外机械力通过致动部151将力作用于可动片159上，当致动部151位移到临界点时产生瞬时动作，使可动片159末端的动触点与接触簧片158定触点快速接通或断开。触点是微动开关的心脏部，经由触点执行电路的打开/关闭操作；连接微动开关和外部电路。
微动开关的所有接触端子上非封闭式组装槽的设置可实现行程开关组件的自动化组装。
如图所示4所示，作为该组装槽的第一实施例，该组装槽153开设在该第一接触端子152与第二接触端子154的末端，使得该组装槽153的开口中心线与对应接触端子的中心线重合，从外观上看，该第一接触端子152与第二接触端子154伸出该下壳体156的部分呈U型构造。
该组装槽设置的目的是为了便于自动化地将该微动开关与其它电子元器件与连接线材组装起来，组装槽开设的位置不一定在接触端子的末端，只要设备机械手能够一次完成连接即可。以下举例组装槽的另外实施例。
作为该组装槽的第二实施例，该组装槽可开设在该至少两个接触端子的相同侧边的边缘，该组装槽的开口中心线与对应接触端子的中心线垂直。比如，该组装槽开设在该第一接触端子152与第二接触端子154的相同左侧边缘或者相同右侧边缘，亦即相同侧边的边缘，使得该组装槽的开口中心线与对应接触端子的中心线垂直，因此机械手可通过一个工位的移动将二极管置入该第一接触端子152与第二接触端子154之间。
作为该组装槽的第三实施例，该组装槽可开设在该至少两个接触端子的相同侧边的边缘，该组装槽的开口中心线与对应接触端子的中心线成夹角。比如，该组装槽开设在该第一接触端子152与第二接触端子154的相同左侧边缘或者相同右侧边缘，亦即相同侧边的边缘，使得组装槽的开口中心线与对应接触端子的中心线成夹角，因此机械手可通过一个工位的移动将二极管置入该第一接触端子152与第二接触端子154之间。
如图4所示，该微动开关中，每一组装槽，比如组装槽153，包括连通的第一收容槽1531与第二收容槽1532，该第一收容槽1531用于置入的二极管管脚和接线端，该第二收容槽1532用于填充焊锡。

该串接线31的接线端置入该第一组装槽和第二组装槽，该第一引线32的接线端置入该第一微动开关15的第一组装槽，该第一引线32另一端的连接端321可以为母插接接头。该第二引线33的接线端置入该第二微动开关16的第二组装槽，该第二引线33另一端的连接端321可以为公插接接头。
