一种行程开关 技术领域
本实用新型属于行程开关结构设计以及应用技术领域，涉及操控机电运动结构用行程开关，具体为一种行程开关。
背景技术
目前市场上的行程开关存在如下问题：
1、防护等级较低
市场上的行程开关普遍采用橡胶垫、橡胶套密封，该结构本身防护等级在IP65左右，无法通过II级绝缘标准，若产品在生产过程中控制不严格，存在胶垫挤压变形偏移，结构件表面光洁度差异等因素导致密封效果失效的风险，从而导致产品无法适用于湿度大、尘埃粒子浓度高的复杂环境中；
2、尺寸较大
市场上的行程开关因其运动结构的特点，及电器间隙爬电距离的要求，开关的体积较大，导致商家在选择开关时经常发生开关与其本身结构件干涉的现象；
3、对多种形式开关的通用性较低
企业在选择开关时常常因为其触点形式、操作头方式、动作方式不一样而选择不同形式型号的开关，有时候为了凑齐开关的品种，不得不从不同厂家采购技术标准参差不齐的开关。
实用新型内容
有鉴于此，本实用新型的目的在于针对上述问题提供一种行程开关，防护等级高、尺寸小且适用多种开关要求。
本实用新型是这样实现的：
一种行程开关，包括壳体，其特征在于：壳体内设有空腔，空腔内设有双环基座，双环基座包括外环基座和内环基座，其中外环基座上设有静触片，内环基座上设有动触片，静触片的静触点和动触片的动触点均在外环基座和内环基座之间；还包括操作头，操作头穿过壳体连接壳体内的连杆，连杆连接动触片并联动控制动触片与静触片的接触和分断。
更进一步地，壳体头端设有导向套，所述操作头的尾部伸入导向套内并与导向套内的连杆头端连接；导向套与空腔之间设有挡板，连杆尾端贯穿挡板与内环基座上的动触片连接；连杆上套设有复位弹簧，复位弹簧设置在操作头和挡板之间。
更进一步地，双环基座为双矩形环，内环基座与外环基座的顶边重合，所述静触片分别设置在外环基座的四个顶点处；内环基座上设有滑轨，滑轨上设有滑块，连杆尾端通过触片弹簧连接滑块，连杆连接的所述动触片分布在滑块两侧，使滑块能够沿着内环基座引导动触片在静触片之间往复滑动，完成动触片与静触片接触和分断。
更进一步地，在操作头和连杆之间设置限位钢球，限位钢球为两个，并通过连接弹簧弹性连接；导向套内壁上设有限位槽，限位槽与限位钢球适配。
更进一步地，壳体上设有外盖；双环基座上设有与之匹配的内盖，内盖与基座连接并且内盖与基座连接整体涂设密封胶层；双环基座与外壳内壁之间填充有密封胶。
更进一步地，导向套与挡板的连接处设有O型密封圈密封。
更进一步地，壳体尾端设有接线孔，接线孔处设有锁线夹。
本实用新型的有益效果是提供了一种行程开关，通过双环基座结构将触点和操作系统浓缩在壳体内腔，大大缩小行程开关整体体积，在满足230V/6AAC-15、230/0.25mADC-13条件下电气间隙和爬电距离的前提下，浓缩了外形尺寸，大幅度扩大了使用范围；密封效果好，防护等级更高；在基本结构不变的情况下，能够实现操作头的多样化，更加通用。

具体实施方式
为了使本技术领域的人员更好地理解本实用新型方案，下面结合附图和具体实施方式对本实用新型作进一步的详细说明。
一种行程开关，如图1所示，包括壳体1和操作头2，壳体头端设有导向套3，操作头2的头端在壳体1外，操作头2的尾部伸入导向套3内并与导向套3内的连杆4头端连接；壳体内设有空腔5，导向套3与空腔5之间设有挡板6，连杆4上套设有复位弹簧7，复位弹簧7设置在操作头2和挡板6之间；复位弹簧7优选宝塔簧。导向套3与挡板6的连接处设有0型密封圈密封8。
空腔5内设有类似“回”字形的双环基座，双环基座包括外环基座9和内环基座10，双环基座为双矩形环，本实施例中外环矩形为倒角，除此实施例外，双环基座也可以是圆角或者其他合适的形状。
根据图2所示，内环基座10与外环基座9的顶边重合，其中外环基座9的四个顶点处分别设有静触片121、122、123以及124，内环基座9上设有滑轨11，滑轨11上设有滑块13，滑块13两侧分布有动触片141和142，静触片的静触点15和动触片的动触点16均在外环基座9和内环基座10之间；结合图3所示的为滑块一侧的动触片的动触点16与静触片上的静触点15分断与接触的配合示意图，图中动触片142的动触点16与与静触片122的静触点15接触，当动触片142向静触片123移动并与之接触时，则为动触片142近静触片123侧的动触点16与静触片123上的静触点15接触。
所述连杆4的尾端贯穿挡板6伸入空腔5中与内环基座9上的动触片连接，连杆连接动触片并联动控制动触片与静触片的接触和分断；连杆尾端通过触片弹簧17与滑块13弹性连接，使滑块能够沿着内环基座引导动触片在静触片之间往复滑动，完成动触片与静触片接触和分断。
壳体上设有外盖；双环基座上设有与之匹配的内盖，内盖与基座连接并且内盖与基座连接整体涂设密封胶层；双环基座与外壳内壁之间填充有密封胶。
壳体尾端设有接线孔18，接线孔处设有锁线夹19；静触片的接线从接线孔进入，用锁线夹归拢固定。
初始状态下，动触片141和142分别与静触片121、122接触，形成开关触点常闭；按动操作头2，连杆4开始下移，带动滑块13和动触片下移，常闭触点断开；持续按动操作头2，连杆继续带动动触片和滑块下移，动触片141和142向静触片123、124靠近，常开触点开始接通，直至滑块13滑至内环基座10尾端，并且触片弹簧17压缩使动触片141 和142分别与静触片124、123接触，常开触点一直接通状态；放松操作头，在复位弹簧的作用下，连杆带动滑块与动触片复位。
上述实施例为直动自动复位式行程开关，在本实施例的基础上，在操作头和连杆之间设置限位装置，使之构成直动非自动复位式行程开关：
在操作头2和连杆4之间设置限位钢球20，限位钢球20为两个，并通过连接弹簧21弹性连接；导向套3内壁上设有限位槽22，限位槽22与限位钢球21适配，这样当常闭触点断开、动触片141、142向静触片123、124靠近的过程中，限位钢球20在操作头的推动下靠近限位槽22，限位钢球10到达限位槽22位置时，连接弹簧21的斥力会使限位钢球20与迅速落入限位槽11内，此时动触片141、142分别与动触片124、123接触，行程开关处于常开状态；但此时，由于连接弹簧弹性，操作头仍可稍稍继续下按一段距离，常开触点也继续保持接通状态。
当需要复位时，只需要向上拉操作头，带动限位钢球脱离限位槽，由于拉力带动作用，动触片和滑块可迅速复位至初始状态。
本实用新型的优点如下：
1、将操纵系统和触点系统浓缩在双环形基座内，在满足大幅度缩小了行程开关的整体尺寸，在满足230V/6AAC-15、230/0.25mADC-13条件下电气间隙和爬电距离的前提下，降低了与机器设备结构件的干涉率，使之安装更为便捷，适用范围更广；
2、双环基座上设置内盖，并填充密封胶，大大提高产品的防护性能，满足II级绝缘标准，本实用新型经测试绝缘电阻大于500M欧，耐电压2500Vlmin时间，接触电阻小于0.3欧；
振动试验机的振幅＜2mm，频率为13.5HZ，振动时间为3h；
