首先参考图1，根据本发明的接触器的分断模块包括：壳体；第一静触头21和第二静触头22；第一动触头31和第二动触头32；动触头支架4，连接到第一动触头31和第二动触头32，配置为在第一方向上运动以致动第一动触头31和第二动触头32在第一方向上运动，从而实现第一动触头31和第一静触头21的接合和分离以及第二动触头32和第二静触头22的接合和分离；第一灭弧室51和第二灭弧室52，在与第一方向垂直的第二方向上设置在动触头支架4的两侧；第一导弧片61，从邻近第一静触头21的第一导弧始端延伸到邻近第一灭弧室51的第一导弧终端611，以将电弧从第一静触头21引导到第一灭弧室51的一侧；第二导弧片62，从邻近第二静触头22的第二导弧始端延伸到邻近第二灭弧室52的第二导弧终端621，以将电弧从第二静触头22引导到第二灭弧室52的一侧；以及偏转件1，安装到壳体，包括设置在第一动触头31和第一灭弧室51之间的 第一引弧部11以将电弧从第一动触头31引导到第一灭弧室51的另一侧，和设置在第二动触头32和第二灭弧室52之间的第二引弧部12以将电弧从第二动触头32引导到第二灭弧室52的另一侧。也就是说，第一导弧终端611和第一引弧部11设置在第一灭弧室51的相对的两侧，并且第二导弧终端621和第二引弧部12设置在第二灭弧室52的相对的两侧。第一灭弧室51和第二灭弧室52中设置有多个灭弧栅片，多个灭弧栅片在第一方向上延伸，并且彼此间隔开一定距离，从而达到灭弧的效果。
下面，详细描述根据本发明的偏转件1的具体构造。
根据本发明的偏转件1包括：沿第一方向延伸且彼此平行的第一引弧部11和第二引弧部12；沿与第一方向垂直的第二方向延伸并且在第二方向上偏置地设置在第一引弧部11和第二引弧部12之间的基部13；连接基部13和第一引弧部11的第一连接部14；以及连接基部13和第二引弧部12的第二连接部15。其中，第一引弧部11设置在第一动触头31和第一灭弧室51之间以将电弧从第一动触头31引导到第一灭弧室51，第二引弧部12设置在第二动触头32和第二灭弧室52之间以将电弧从第二动触头32引导到第二灭弧室52。
优选地，第一引弧部11、第一连接部14、基部13、第二连接部15、第二引弧部12可以由板材一体形成，例如由金属板材冲压而一体形成。如此，偏转件1的制造简单、成本低。
优选地，基部13可以设置有延伸穿过基部13的基部开口131。如图2-4所示，可以在基部13处开设基部开口131，以减轻重量和节省材料。
优选地，第一连接部14在靠近第一引弧部11处设置有第一通孔141，以允许第一动触头31移动通过；第二连接部15在靠近第二引弧部12处设置有第二通孔151，以允许第二动触头32移动通过，第一通孔141和第二通孔151的宽度略小于偏转件1的宽度。第一通孔141和第二通孔151的设计防止了与第一动触头31和第二动触头32的干涉。
基部13设置在分断模块的远离第一静触头21和第二静触头22的一端。可选地，第一连接部14在第一引弧部11的远离基部13的第一远端111连接到第一引弧部11并且所述第二连接部15在第二引弧部12的远离基部13的第二远端121连接到第二引弧部12，如图2和4所示。或者，第一连接部14在第一引弧部11的靠近基部13的第一近端112连接到第一引弧部11并且第二连接部15在第二引弧部12的靠近基部13的第二近端122连接到第二引弧部12，如图3所示。
优选地，第一连接部14在靠近基部13处具有第一阻挡部142，第二连接部15在靠近基部13处具有第二阻挡部152，第一阻挡部142和第二阻挡部152为实心的，以分别阻挡从第一灭弧室51和第二灭弧室52溢出的污染物靠近动触头组件，从而保护动触头接触部分免受侵蚀，防止动触头组件受到来自灭弧室的污染。如图1所示，例如，从第一灭弧室51溢出的污染物被第一连接部14的第一阻挡部142阻挡，不能进入到包括第一动触头31、第二动触头32、动触头支架4的中间空间中，防止动触头被污染。
优选地，第一引弧部11在其远离基部13的第一远端111处具有沿第一方向延伸的第一突出部113，第一突出部113的宽度小于第一引 弧部11的主体的宽度；第二引弧部12在其远离基部13的第二远端121处具有沿第一方向延伸的第二突出部123，第二突出部123的宽度小于第二引弧部12的主体的宽度。第一突出部113和第二突出部123分别更靠近第一动触头31和第二动触头32，而且形成为更尖，有助于引导来自第一动触头31和第二动触头32的电弧。
可选地，第一连接部14和第二连接部15分别配置为直线延伸，如图4所示。或者，第一连接部14和第二连接部15分别形成为由沿不同方向延伸的两个以上的段组成，如图2和3所示，分别形成为由两个段组成。需要理解的是，还可以由三个以上的段组成。而且，组成第一连接部14或第二连接部15的段之间、以及第一连接部14或第二连接部15与基部13、第一引弧部11、第二引弧部12之间可以采用圆弧过渡，也可以不采用圆弧过渡。
<第一实施例>
下面根据图2详细描述根据本发明的第一实施例的偏转件1。
如图2所示，偏转件1形成为轴对称的大致M形，由在第一方向上延伸的第一引弧部11、连接第一引弧部11和基部13的第一连接部14、在第二方向上延伸的基部13、连接基部13和第二引弧部12的第二连接部15、在第一方向上延伸的第二引弧部12顺序连接而一体形成，具有沿与第一方向和第二方向均垂直的第三方向(也称为宽度方向)的基本上一致的宽度。
第一引弧部11和第二引弧部12分别形成为片状，即在第一 方向和宽度方向上延伸。第一引弧部11在其远离基部13的第一远端111处具有沿第一方向延伸的第一突出部113，第一突出部113的宽度小于第一引弧部11的主体的宽度。如图2所示，第一突出部113从第一引弧部11的第一远端111的中部远离第一引弧部11的主体突出，结合图1可知，第一突出部113更靠近第一动触头31，因此，第一突出部113的设置有利于引导来自第一动触头31的电弧。类似地，第二引弧部12上设置有第二突出部123，在此不再赘述。
基部13形成为具有基部开口131的片状，基部开口131的宽度略小于偏转件1的宽度，此处“略小于”是指基部开口131的宽度可以大于偏转件1的宽度的三分之二、四分之三或五分之四等，从而可以减轻偏转件1的重量。基部13在第一方向上从第一引弧部11和第二引弧部12偏置。具体地，如图1所示，基部13比第一引弧部11和第二引弧部12更远离第一静触头21和第二静触头22。

<第二实施例>
下面根据图3详细描述根据本发明的第二实施例的偏转件1。
如图3所示，偏转件1形成为轴对称的大致山形，由在第一方向上延伸的第一引弧部11、连接第一引弧部11和基部13的第一连接部14、在第二方向上延伸的基部13、连接基部13和第二引弧部12的第二连接部15、在第一方向上延伸的第二引弧部12顺序连接而一体形成，具有沿与第一方向和第二方向均垂直的第三方向(也称为宽度方向)的宽度。
第一引弧部11和第二引弧部12分别形成为片状，即在第一方向和宽度方向上延伸。第一引弧部11和第二引弧部12的宽度大于第一连接部14和第二连接部15的宽度，有助于通过第一引弧部11和第二引弧部12将偏转件1固定到壳体。第一引弧部11在其远离基部13的第一远端111处具有沿第一方向延伸的第一突出部113，第一突出部113的宽度小于第一引弧部11的主体的宽度。如图3所示，第一突出部113从第一引弧部 11的第一远端111的中部远离第一引弧部11的主体突出，可以想象，第一突出部113更靠近第一动触头31，因此，第一突出部113的设置有利于引导来自第一动触头31的电弧。类似地，第二引弧部12上设置有第二突出部123，在此不再赘述。
基部13形成有基部开口131，基部开口131的宽度略小于偏转件1的宽度，此处“略小于”是指基部开口131的宽度可以大于偏转件1的宽度的三分之二、四分之三或五分之四等，从而可以减轻偏转件1的重量。基部13在第一方向上从第一引弧部11和第二引弧部12偏置。具体地，如图1所示，基部13比第一引弧部11和第二引弧部12更远离第一静触头21和第二静触头22。基部13具有沿宽度方向向两侧延伸的突起，有助于通过基部13将偏转件1固定到壳体。
第一连接部14在第一引弧部11的靠近基部13的第一近端112连接到第一引弧部11并且第二连接部15在第二引弧部12的靠近基部13的第二近端122连接到第二引弧部12。第一连接部14由在第二方向上延伸并且连接到第一引弧部11的第一近端112的第一段和直线连接第一段与基部13的第二段组成，第二段延伸的方向横向于第一方向和第二方向。第一段的尺寸小于第二段的尺寸，需要说明的是，第一段和第二段的尺寸可以根据需要设置，不限于此。第一连接部14在靠近第一引弧部11处设置有第一通孔141，以允许第一动触头31移动通过。具体地，第一通孔141设置在第一段处，或设置在第一段和第二段的靠近第一段的部分，这取决于第一段和第二段的尺寸。第一通孔141的宽度略小于偏转件1的宽度，此处“略小于”是指第一通孔141的宽度可以大于偏转件1的宽度的三分 之二、四分之三或五分之四等，以避免与第一动触头31干涉，充分利用空间，且保证自身刚度。另外，第一连接部14在靠近基部13处具有第一阻挡部142，具体地，第一阻挡部142设置在第二段的靠近基部13处，第一阻挡部142为实心的，以阻挡从第一灭弧室51溢出的污染物靠近动触头组件，例如防止污染物污染第一动触头31。第二连接部15与第一连接部14镜像对称，在此不再赘述。
<第三实施例>
下面根据图4详细描述根据本发明的第一实施例的偏转件1。
如图4所示，偏转件1形成为轴对称的大致M形，由在第一方向上延伸的第一引弧部11、连接第一引弧部11和基部13的第一连接部14、在第二方向上延伸的基部13、连接基部13和第二引弧部12的第二连接部15、在第一方向上延伸的第二引弧部12顺序连接而一体形成，具有沿与第一方向和第二方向均垂直的第三方向(也称为宽度方向)的宽度。
第一引弧部11和第二引弧部12分别形成为片状，即在第一方向和宽度方向上延伸。第一引弧部11和第二引弧部12的宽度大于第一连接部14和第二连接部15的宽度，有助于通过第一引弧部11和第二引弧部12将偏转件1固定到壳体。第一引弧部11在其远离基部13的第一远端111处具有沿第一方向延伸的第一突出部113，第一突出部113的宽度小于第一引弧部11的主体的宽度，例如与第一连接部14的第一通孔141的宽度一致。如图4所示，第一突出部113从第一引弧部11的第一远端111的中部远离第一引弧部11的主体突出，可以想象，第一突出部113更靠近第 一动触头31，因此，第一突出部113的设置有利于引导来自第一动触头31的电弧。类似地，第二引弧部12上设置有第二突出部123，在此不再赘述。
基部13形成有基部开口131，基部开口131的宽度略小于偏转件1的宽度，此处“略小于”是指基部开口131的宽度可以大于偏转件1的宽度的三分之二、四分之三或五分之四等，从而可以减轻偏转件1的重量。基部13在第一方向上从第一引弧部11和第二引弧部12偏置。具体地，如图1所示，基部13比第一引弧部11和第二引弧部12更远离第一静触头21和第二静触头22。基部13具有沿宽度方向向两侧延伸的突起，有助于通过基部13将偏转件1固定到壳体。
第一连接部14在第一引弧部11的远离基部13的第一远端111连接到第一引弧部11并且第二连接部15在第二引弧部12的远离基部13的第二远端121连接到第二引弧部12。第一连接部14形成为直线连接第一引弧部11与基部13。第一引弧部11的第一远端111与第一连接部14之间、第一连接部14与基部13之间使用圆弧过渡。第一连接部14在靠近第一引弧部11处设置有第一通孔141，以允许第一动触头31移动通过。具体地，第一通孔141的长度大致为第一连接部14的一半，需要注意的是，第一通孔141的尺寸与第一动触头31的尺寸和偏转件1的整体尺寸相关，不限于此。第一通孔141的宽度略小于偏转件1的宽度，此处“略小于”是指第一通孔141的宽度可以大于偏转件1的宽度的三分之二、四分之三或五分之四等，以避免与第一动触头31干涉，充分利用空间，且保证自身刚度。另外，第一连接部14在靠近基部13处具有第一阻挡部142，第一阻挡部142为实心的，以阻挡从第一灭弧室51溢出的污染物靠近动触头组 件，例如防止污染物污染第一动触头31。第二连接部15与第一连接部14镜像对称，在此不再赘述。
通过使用上述偏转件1，可以保护动触头接触部分免受侵蚀，防止动触头组件受到来自灭弧室的污染，减少电弧停滞，提高灭弧性能。
进一步地，通过实验表明，对于不同的接触器，使用上述根据不同实施例的偏转件1的不同形状具有不同的性能，例如，不同的电弧持续时间、不同的动触头侵蚀情况、不同的电气耐久性等。可以根据实际情况选用不同形状的偏转件1。
上文中参照优选的实施例详细描述了本发明所提出的偏转件1、分断模块和接触器的示范性实施方式，然而本领域技术人员可理解的是，在不背离本发明理念的前提下，可以对上述具体实施例做出多种变型和改型，且可以对本发明提出的各种技术特征、结构进行多种组合，而不超出本发明的保护范围。
