具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式。虽然本说明书中使用相对性的用语，例如“上”、“下”来描述图标的一个组件对于另一组件的相对关系，但是这些术语用于本说明书中仅出于方便，例如根据附图中所述的示例的方向。能理解的是，如果将图标的装置翻转使其上下颠倒，则所叙述在“上”的组件将会成为在“下”的组件。其他相对性的用语，例如“顶”、“底”等也作具有类似含义。当某结构在其它结构“上”时，有可能是指某结构一体形成于其它结构上，或指某结构“直接”设置在其它结构上，或指某结构通过另一结构“间接”设置在其它结构上。
用语“一个”、“一”、“该”和“所述”用以表示存在一个或多个要素/组成部分/等；用语“包括”和“具有”用以表示开放式的包括在内的意思并且是指除了列出的要素/组成部分/等之外还可存在另外的要素/组成部分/等；用语“第一”、“第二”等仅作为标记使用，不是对其对象的数量限制。
如图10至图14所示，图10示出的是本公开实施例的继电器的俯视示意图。图11示出的是本公开实施例的继电器在一个视角下的立体示意图。图12示出的是本公开实施例的继电器在另一个视角下的立体示意图。图13示出的是本公开实施例的继电器的示意图，其中省略了外壳。图14示出的是图13中A-A的剖视图。本公开实施例的继电器包括外壳1100、接触容器10、一对静触点引出端20、第一导磁体40、推动杆组件50和电磁铁单元1200。
作为一示例，外壳1100包括第一壳体1110和第二壳体1120，第一壳体1110和第二壳体1120相卡接，以形成用于容纳接触容器10、推动杆组件50和电磁铁单元1200的腔室。
接触容器10具有接触腔室101，一对静触点引出端20连接于接触容器10。一对静触点引出端20的其中一个作为电流流入的端子，另一个作为电流流出的端子。部分静触点引出端20伸入接触腔室101内，用于与推动杆组件50的动簧片54接触或分离。部分静触点引出端20外露于接触容器10的外壁面。
静触点引出端20的底部作为静触点。可以理解的是，静触点可以是一体或分体地设置在静触点引出端20的底部。
接触容器10包括轭铁板13和绝缘罩11a，绝缘罩11a罩设于轭铁板13的一侧面， 以形成接触容器10的接触腔室101。轭铁板13具有与接触腔室101连通的第一通孔131，推动杆组件50可移动地穿设于第一通孔131。
绝缘罩11a包括陶瓷罩11和框片12。陶瓷罩11通过框片12与轭铁板13连接。框片12可以为呈环状结构的金属件，如铁镍合金，且框片12的一端连接于陶瓷罩11的开口边缘，例如框片12和陶瓷罩11的开口边缘之间通过激光焊、钎焊、电阻焊或胶粘等方式相连接。框片12的另一端连接于轭铁板13，同样框片12和轭铁板13之间也可以通过激光焊、钎焊、电阻焊或胶粘等方式相连接。在陶瓷罩11和轭铁板13之间设置一框片12，可方便陶瓷罩11和轭铁板13的连接。
请继续参阅图11，继电器还包括金属罩1410，金属罩1410连接于轭铁板13背向绝缘罩11a的一侧，且金属罩1410罩设于轭铁板13上的第一通孔131。金属罩1410与轭铁板13围成一用于容纳电磁铁单元1200的静铁芯1230和动铁芯1240的腔室，下文将详细说明。
电磁铁单元1200包括线圈架1210、线圈1220、静铁芯1230、动铁芯1240和复位件1250。线圈架1210呈中空筒状，且采用绝缘材料形成。金属罩1410穿设在线圈架1210内。线圈1220环绕线圈架1210。静铁芯1230固定设置在金属罩1410内，且部分静铁芯1230伸入第一通孔131。静铁芯1230具有第二通孔1231，第二通孔1231与第一通孔131的位置对应设置，用于供推动杆组件50的杆部51穿设其中。动铁芯1240可移动地设置在金属罩1410内，且与静铁芯1230相对设置，动铁芯1240连接杆部51，用于当线圈1220通电时，动铁芯1240被静铁芯1230吸引。动铁芯1240与杆部51可以采用螺接、铆接、焊接或其他方式连接。
复位件1250位于金属罩1410内部，且复位件1250设置在静铁芯1230和动铁芯1240之间，用于当线圈1220断电时，使动铁芯1240复位。复位件1250可以为弹簧，并套设于杆部51的外部。
第一导磁体40设于接触容器10的接触腔室101内，且相对于接触容器10固定设置。
作为一示例，第一导磁体40可以直接连接于接触容器10，也可以通过连接件30连接于接触容器10。
在本实施例中，第一导磁体40通过连接件30连接于陶瓷罩11。
如图1至图4、图11所示，图1示出的是本公开第一实施例的推动杆组件50的侧视示意图。图2示出的是图1的分解示意图。图3示出的是图1中X处的局部放大图。图4示出的是图1中B-B的剖视图。
推动杆组件50包括杆部51、底座52、可动构件53、弹性件56和限位结构57。杆部51可移动的穿设于第一通孔131和第二通孔1231。杆部51的一端与底座52连接，杆部51的另一端与动铁芯1240连接。在继电器的线圈1220通电时，动铁芯1240能够带动杆部51移动，从而实现继电器触点的闭合。弹性件56的一端抵接于底座52，弹性 件56的另一端抵接于可动构件53，弹性件56提供弹性力，以使可动构件53具有向继电器的静触点引出端20移动的趋势。
可以理解的是，本公开实施例中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或组件。
可以理解的是，弹性件56可以为弹簧，但不以此为限。
限位结构57连接于底座52和可动构件53，用于限制可动构件53相对于底座52的移动范围。限位结构57包括相配合的限位孔572和限位部571，限位孔572包括沿可动构件53的运动方向D1相对设置的第一端573和第二端574，第二端574的孔径大于第一端573的孔径，限位部571在限位孔572的第一端573和第二端574之间可移动地穿设。
当可动构件53不与静触点引出端20接触时，在弹性件56的作用下，限位部571位于限位孔572的第一端573。当可动构件53与静触点引出端20接触，且完成超行程的过程中，限位部571由限位孔572的第一端573向第二端574移动。由于限位孔572的第二端574的孔径大于第一端573的孔径，故限位孔572呈现“一端大另一端小”的结构，使得在超行程的过程中，限位部571与限位孔572的孔壁之间的间隙变大，可防止可动构件53相对于底座52的运动过程中，限位部571与限位孔572的孔壁发生摩擦卡涩。同时，限位孔572的第一端573的孔径较小，又不影响在初始状态限位部571与限位孔572的限位配合，避免可动构件53相对于底座52发生晃动。
需要说明的是，为了实现在初始状态，可动构件53与底座52的限位，限位孔572的第一端573的孔径大小应与限位部571的形状相适配，使得当限位部571位于限位孔572的第一端573时，限位部571能够与限位孔572的孔壁实现限位。
在本实施例中，底座52通过限位结构57直接与可动构件53连接，使得底座52与可动构件53之间的装配更加简单。并且，由于可动构件53上方并不存在其余部件，故在超行程过程中，避免了该其余部件与第一导磁体40发生运动干涉。
可以理解的是，限位孔572可以为通孔，也可以为盲孔。
请继续参阅图1至图4，由限位孔572的第一端573向第二端574的方向上，限位孔572的孔径逐渐增大。在超行程过程中，限位部571由限位孔572的第一端573向第二端574移动的过程中，限位部571与限位孔572的孔壁之间的间隙逐渐增大。
进一步地，限位孔572的孔壁包括相对设置的第一平面575和第二平面576以及相对设置的第一斜面577和第二斜面578，第一斜面577的一端和第二斜面578的一端均连接于第一平面575的两端，第一斜面577的另一端和第二斜面578的另一端均连接于第二平面576的两端。
在本实施例中，限位孔572的形状大致为一等腰梯形，但不以此为限。例如，限位孔572的形状还可以为一普通梯形，即第一斜面577与第二斜面578的斜率不相等。或者，限位孔572的形状还可以为一三角形，优选的，该三角形可以为一等腰三角形。
当然，在其他实施方式中，沿着限位孔572的第一端573至第二端574的方向上，限位孔572的孔径也可以不是逐渐增大的，例如限位孔572的孔壁还可以包括等径段和扩径段。举例来说，由第一端573至第二端574，限位孔572的孔壁可以依次包括扩径段、等径段、扩径段、等径段等。
如图3所示，限位部571具有第一弧形表面571a，用于在限位部571位于限位孔572的第一端573时，第一弧形表面571a与限位孔572的孔壁实现限位。
在本实施例中，通过将限位部571的外侧壁设计为包括第一弧形表面571a，使得第一弧形表面571a与限位孔572的孔壁之间为线接触，线接触降低了限位部571与限位孔572的孔壁之间的摩擦力。当限位部571与限位孔572产生相对移动时，更加不易发生卡涩。
底座52设有限位孔572，可动构件53包含限位部571。当然，在其他实施方式中，限位孔572也可以设置在可动构件53上，限位部571设置在底座52上。
可以理解的是，可动构件53包括动簧片54和与动簧片54固定连接的第二导磁体55。动簧片54用于与继电器的静触点引出端接触或分离。至少部分第二导磁体55和第一导磁体40分别位于动簧片54的两个相对的侧面。第二导磁体55可以与第一导磁体40形成抗短路环电磁结构，抗短路环电磁结构能够在第一导磁体40和第二导磁体55之间形成磁吸力以克服短路电流产生的斥力，防止动簧片54与静触点引出端弹开。
可以理解的是，第一导磁体40可以为一字型结构，第二导磁体55可以为U型结构。第一导磁体40和第二导磁体55均可以采用铁，钴，镍，及其合金等材料制作而成。
此外，第一导磁体40可以包括多片叠置的导磁片。第二导磁体55也可以包括多片叠置的导磁片，或者，第二导磁体55包括多个并排布置的U型导磁体。
当然，在其他实施方式中，可动构件53可以包含动簧片54而不包含第二导磁体55。
为了方便说明，下面以可动构件53包含动簧片54和第二导磁体55为例进行说明，但不限定于此。
如图1至图4，在本实施例中，底座52设有限位孔572，第二导磁体55设有限位部571。第二导磁体55包括底部551、第一侧部552和第二侧部553。第一侧部552和第二侧部553沿着动簧片54的宽度方向D3设置并分别连接于底部551的两端。第一侧部552和第二侧部553分别设置于动簧片54的宽度方向D3的两个相对的侧边。第一侧部552和第二侧部553均设有限位部571。
底座52包括基部521以及连接于基部521且相对设置的第一限位件522和第二限位件523，第一侧部552与第一限位件522对应设置，第二侧部553与第二限位件523对 应设置，第一限位件522和第二限位件523均开设有限位孔572。
第一限位件522朝向第一侧部552的一侧表面以及第二限位件523朝向第二侧部553的一侧表面包括第二弧形表面524。
在本实施例中，通过将第一限位件522朝向第一侧部552的侧表面以及第二限位件523朝向第二侧部553的侧表面设计为均包括第二弧形表面524，使得两个第二弧形表面524分别与第一侧部552和第二侧部553为线接触，线接触降低了第一侧部552与第一限位件522之间以及第二侧部553与第二限位件523之间的摩擦力。当第二导磁体55相对于底座52产生相对移动时，更加不易发生卡涩。并且，能够避免产生刮屑而污染继电器的接触腔室。
第一侧部552和第二侧部553位于第一限位件522和第二限位件523之间。第一侧部552背离第二侧部553的一侧以及第二侧部553背离第一侧部552的一侧均一体凸设有限位部571。
作为一示例，限位部571的形成可以采用冲压第一侧部552/第二侧部553的侧面，而使限位部571形成冲苞结构。冲苞结构于第一侧部552/第二侧部553的具体位置可以根据结构灵活调整。
在本实施例中，由于两个限位部571分别凸设于第一侧部552背离第二侧部553的一侧，以及第二侧部553背离第一侧部552的一侧，使得第一侧部552和第二侧部553能够分别与第一限位件522和第二限位件523接触充分，进而确保第二导磁体55与底座52限位时的稳定性，且不会影响导磁效率。
在一实施方式中，限位部571可以为长条形。当限位部571位于限位孔572的第一端573时，长条形面积较大的侧面与限位孔572的孔壁接触。通过将限位部571的面积较大的表面与限位孔572的孔壁接触，有效地避免了在初始状态动簧片54相对于底座52发生摆动的情况，降低了动簧片54发生回跳、回弹的概率。
如图5所示，图5示出的是本公开第二实施例的推动杆组件50的分解示意图。第二实施例与上述第一实施例的相同之处不再赘述，其不同之处在于：
限位部571包括两个凸包结构。两个凸包结构沿着动簧片54的长度方向D2间隔设置。双凸包结构的设计，有效地避免了在初始状态动簧片54相对于底座52发生摆动，降低了动簧片54发生回跳、回弹的概率。
可以理解的是，运动方向D1、长度方向D2和宽度方向D3两两相互垂直。
如图6所示，图6示出的是本公开第三实施例的推动杆组件50的分解示意图。第三实施例与上述第一实施例的相同之处不再赘述，其不同之处在于：
限位部571为铆钉579，铆钉579铆接于第二导磁体55的第一侧部552和/或第二侧部553。
如图7所示，图7示出的是本公开第四实施例的推动杆组件50的分解示意图。第四 实施例与上述第一实施例的相同之处不再赘述，其不同之处在于：限位部571设置于第二导磁体55的底部551上。
具体来说，第二导磁体55包括底部551、第一侧部552和第二侧部553。沿着动簧片54的宽度方向D3，底部551的两个相对的侧边均一体凸设有限位部571。第一侧部552和第二侧部553沿着动簧片54的宽度方向D3分别连接于底部551的两端。第一侧部552和第二侧部553分别设置于动簧片54的宽度方向D3的两个相对的侧边。
底座52包括基部521以及连接于基部521且相对设置的第一限位件522和第二限位件523，第一限位件522和第二限位件523均开设有限位孔572。
如图8所示，图8示出的是本公开第五实施例的推动杆组件50的分解示意图。第五实施例与第一实施例的相同之处不再赘述，其不同之处在于：
底座52包括基部521以及连接于基部521且相对设置的第一限位件522和第二限位件523，第一限位件522和第二限位件523均开设有限位孔572。可动构件53还包括固定连接于第二导磁体55的固定件58，固定件58的相对两侧均设有限位部571。
第一限位件522、第二限位件523以及基部521可以通过一体注塑成型，但不以此为限。
固定件58具有穿孔581，弹性件56穿设于该穿孔581，且弹性件56的两端分别抵接于第二导磁体55和底座52。
如图9所示，图9示出的是本公开第六实施例的推动杆组件50的分解示意图。第六实施例与第一实施例的相同之处不再赘述，其不同之处在于：
限位部571凸设于推动杆组件50的底座52的两个相对的侧边。可动构件53还包括固定连接于第二导磁体55的固定件58，固定件58设有限位孔572。
需要说明的是，固定件58呈倒U型结构，设于固定件58上的限位孔572的第一端573和第二端574的位置刚好与第一至第五实施例的限位孔572的相反。
具体来说，如图9所示，限位孔572的第一端573位于下方，而第二端574位于上方，第二端574的孔径大于第一端573的孔径。
如图2、图5至图8所示，限位孔572的第一端573位于上方，而第二端574位于下方。
可以理解的是，本公开提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合，此处不再一一举例说明。
