请参阅图1，本申请提供一种定子组件的实施例，所述定子组件100适用于电子膨胀阀，旨在减少定子组件100的线圈组件120因高压脉冲而产生放电的情况出现，进而提高电子膨胀阀的安全性能。
请参阅图1至图3，在本申请定子组件的一实施例中，定子组件100包括外壳110、线圈组件120及固定件130；其中，外壳110的外表面设置有安装口111；线圈组件120设于外壳110内，线圈组件120包括供线圈122安装的金属壳121；固定件130经安装口111插入而与所述金属壳121连接固定，固定件130适用于固定到电子膨胀阀的导通管上，以将所述金属壳121和所述导通管电性导通。
具体说来，定子组件100的外壳110采用塑料材料，以使得该外壳110不具导电性，提高定子组件100的安全性能。定子组件100的线圈组件120的金属壳121则采用具有金属材料制成，如冷轧板，以使得该金属壳121同时具有导电性和导磁性。线圈组件120的线圈122绕设在金属壳122内。定子组件100设置有沿线圈组件120的轴线延伸的通道；该线圈组件120的金属壳121的内壁面设置有位于该通道内的磁极齿121a。
请参阅图1和图7，当将该定子组件100与电子膨胀阀的阀体200装配时，先将阀体200穿插在定子组件100的通道内，阀体200的壳体210与磁极齿121a接触，从而使得阀体200与定子组件100嵌套在一起；然后再将定子组件100外侧的固定件130与阀体200的导通管固定连接，使得线圈组件120通过导通管与大地电性导通。因此，在定子组件100的线圈组件120产生瞬间数kV的脉冲电压（如雷击等）时，线圈组件120上的电流通过该固定件130传导到电子膨胀阀的导通管上，进而通过该导通管传导出去（如传导到地面），从而不易在线圈组件120的磁极齿121a和阀体200的壳体210之间产生放电，进而避免干扰周围的电路或击穿阀体200的壳体210。
应说明的是，电子膨胀阀的阀体200的导通管包括有第一导通管211和第二导通管212；第一导通管211和第二导通管212其中一者作为进口导通管，另一者出口导通管。定子组件100的固定件130可以与第一导通管211固定连接，也可以与第二导通管212固定连接，在此没有限定。
在本实施例中，考虑到由于线圈组件120被外壳110包裹于其中，受到外壳110的阻隔，固定件130不易与线圈组件120的金属壳121直接连接装配。因此，在外壳110的外表面设置有安装口111，使得线圈组件120的金属壳121可从安装口111显露出来，从而操作人员可将固定件130可经所述安装口111插入到外壳110的内部，进而与金属壳121连接固定。
对于该固定件130而言，由于固定件130用于将线圈组件120和电子膨胀阀的阀体200电性连通，因此，固定件130应当采用具有导电性能的材料制成，例如，固定件130采用金属材料制成。值得一提的是，为避免固定件130影响到线圈组件120的磁力，在一实施例中，固定件130采用不具有磁性的金属材料制成。
至于固定件130与金属壳121的固定方式，可以是焊接或铆接；固定件130与电子膨胀阀的导通管的连接方式，则可以是夹持连接或卡持连接等，具体在后文还有详细介绍。
本申请的技术方案，通过定子组件100的外壳110外侧配置固定件130，该固定件130与线圈组件120的金属壳121电性连接，该固定件130适用于夹持固定到电子膨胀阀的阀体200上，以将线圈组件120和电子膨胀阀的阀体200电性连通，从而在线圈组件120产生瞬间数kV的脉冲电压（如雷击等）时，避免在线圈组件120的磁极齿121a和阀体200的壳体210之间产生放电现象（详细可参见前述说明，在此不赘述）。基于此，为方便固定件130与线圈组件120的金属壳121连接固定，还在外壳110的外表面设置有安装口111，使得线圈组件120的金属壳121可从安装口111显露出来，从而操作人员可将固定件130可经安装口111插入到外壳110的内部，进而与金属壳121连接固定。
请参阅图3至图5，在一实施例中，外壳110的外侧面设置有沿所述安装口111的周缘设置的环形凸部112，在环形凸部112的内侧形成有安装槽113，以供固定件130安装。具体地，该安装槽113与安装口111连通；安装该固定件130时，将固定件130的基部131伸入到安装槽113内，并使基部131贴靠到金属壳121的表面，再将基部131和金属壳121铆接或焊接固定。
上述环形凸部112不仅增大了固定件130和金属壳121装配的空间，可容置较多的焊料或密封材料；并且，环形凸部112将安装口111包围起来，从而外壳110外表面上的水滴不易落入到安装口111，也就不易进入到线圈组件120上，起到较佳的防水作用。
请参阅图3至图5，在一实施例中，固定件130包括基部131及自基部131的两端延伸出的两个夹持臂132；其中，基部131固定于安装槽113内，并与金属壳121连接固定，两个夹持臂132适用于夹持于阀体200的导通管上。
具体地，固定件130的基部131与两个夹持臂132配合呈类U形设置；其中，基部131与金属壳121连接固定，且该连接亦为电性连接；两个夹持臂132呈相对设置，两个夹持臂132配合夹持阀体200的导通管上，从而与导通电性导通。当然，固定件130的结构并不局限与此。在其他实施例中，固定件130设计为弹性卡扣、或卡爪等具有卡持固定功能的结构。
进一步地，金属壳121具有与安装槽113相对的连接面121b，基部131设置有固定孔131a，基部131通过该固定孔131a与连接面121b连接固定。至于固定孔131a与连接面121b的连接方式，以下列举两种实施。
其中一实施方式中，连接面121b设置有伸入安装口111的凸起部121c；基部131的固定孔131a供凸起部121c插置配合连接。在一实施例中，固定孔131a和凸起部121c过盈配合，两者配合后即可将固定件130与金属壳121连接固定。由于凸起部121c属于金属壳121的一部分，所以，固定孔131a和凸起部121c插置配合后，两者电性接触并导通。
在上述将固定件130的基部131伸入到安装槽113内的过程中，金属壳121的连接面121b上的凸起部121c对应插入基部131的固定孔131a内，该凸起部121c与固定孔131a过盈配合，从而将固定件130限定在安装槽113内。这样就可以不必用手扶住固定件130，即可对固定件130进行焊接或卡接等操作。
至于凸起部121c的数量，凸起部121c的数量可以为一个或者两个或两个以上，具体在此不设限定。根据凸起部121b的数量，合理配置固定件130上的固定孔131a的数量，使得每一凸起部121b对应有与之插置配合的固定孔131a。在一实施例中，固定件130设置有至少两个固定孔131a；金属壳121设置有至少两个凸起部121b，每一个凸起部121b插置于与其相对的固定孔131a内。
在另一实施方式中，基部131在固定孔131a所在位置与连接面121b焊接连接。焊接时，焊接材料在基部131的固定孔131a和连接面121b之间熔融并凝固形成有焊接结构，该焊接结构不仅将固定件130的基部131和连接面121b连接固定，且还能将此两者电性导通，实现连接面121b和金属壳121电性导通。
基于上述任意一实施例，考虑到如果金属壳121的连接面121b通过安装槽113直接裸露在环境中，环境中的水汽可能会经该安装槽113进入到金属壳121内，进而易于引发线圈组件120电路短路现象。鉴于此，为避免出现这种情况，在一实施例中，定子组件100还包括填充在安装槽113内的密封材料140，所述密封材料140至少覆盖连接面121b。
具体在此，密封材料140填充满安装槽113，以封盖该安装槽113，从而使得环境中的水滴难以通过安装槽113流入到金属壳121内，确保线圈组件120安全稳定工作。至于密封材料140的具体类型，密封材料140宜采用具有绝缘性能和防水性能的材料制成，例如硅胶材料、橡胶材料等。
请参阅图4至图6，基于上述任意一实施例，每一个夹持臂132包括与基部131连接的第一臂部132a及自第一臂部132a延伸出的第二臂部132b，第二臂部132b朝背离另一个夹持臂132的方向呈弯折设置，以在两个夹持臂132的第二臂部132b之间限定出用于夹持导通管的夹持区132c。
具体说来，固定件130的两个夹持臂132具有弹性，从而使得该两个夹持臂132可弹性张开和夹紧。将固定件130卡接到阀体200上时，先把固定件130的两个夹持臂132张开到阀体200的导通管两侧，松开固定件130的两个夹持臂132，两个夹持臂132即可将导通管夹持于夹持区132c内，从而实现将固定件130卡持固定在阀体200上。拆卸时，对两个夹持臂132施加外力使其张开，即可释放阀体200，进而可将固定件130拆卸下来。
进一步地，每一个夹持臂132的第一臂部132a朝背离另一个夹持臂132的方向呈弯折设置，这样可使得每一个夹持臂132上均形成有两个弯折的位置，从而可增大夹持臂132的弹性，进而使得固定件130可适配于夹持更多不同管径大小的导通管，提高固定件130的适用性，也即是电子膨胀阀的适用性。
请参阅图7和图8，本申请还提供一种电子膨胀阀，所述电子膨胀阀包括阀体200和定子组件100，定子组件100嵌套在阀体200上；其中，所述阀体200设置第一导通管211和第二导通管212，第一导通管211和第二导通管212均属于阀体200的导通管；定子组件100的具体结构参照上述实施例。定子组件100的固定件130与第一导通管211或第二导通管212连接固定。由于本电子膨胀阀采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
具体说来，第一导通管211作为进口导通管，第二导通管212作为出口导通管。由于第一导通管211和第二导通管212通常都是金属管，例如铜管，从而使得第一导通管211和第二导通管212都具有良好的导电性能。基于此，可将固定件130与该阀体200的第一导通管211或第二导通管212连接固定，即可通过大地导通。具体地，由于第一导通管211沿垂直于定子组件100的通道123轴向（横向）延伸，第二导通管212沿定子组件100的通道123轴向延伸，从而第一导通管211较为靠近固定件130，并与该固定件130相对。因此，可选将固定件130夹持固定在第一导通管211，距离较近夹持难度较小。
请参阅图7至图8，至于固定件130与第一导通管211和/或第二导通管212卡接的方式，如前述实施例说明，固定件130具有两个夹持臂132（如图5所示），通过该两个夹持臂132夹持在第一导通管211或第二导通管212上，从而将固定件130与第一导通管211或第二导通管212连接固定。当然，固定件130与第一导通管211或第二导通管212连接的方式并不局限于此，在其他实施例中也可以采用螺钉固定或捆扎固定等方式。
本申请还提供一种制冷设备，所述制冷设备包括冷媒循环管路和电子膨胀阀，电子膨胀阀安装于所述冷媒循环管路上。电子膨胀阀的具体结构参照上述实施例。由于本制冷设备采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
