本申请的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请中的具体含义。
参照图1和图2所示，本申请一种实施例的定子组件1000，可以用于电机，例如塑封电机、洗涤电机等。本申请实施例的定子组件1000包括定子铁芯100、绝缘框架200、绕组130、出线座210、盖板220和多个第一端子300。绝缘框架200嵌设于定子铁芯100，绕组130绕设于绝缘框架200，且绕组130具有多根第一引出线110。出线座210和绝缘框架200连接且位于定子铁芯100的外部，例如出线座210和绝缘框架200一体成型，或者通过卡扣、螺钉等方式和绝缘框架200连接，或者出线座210也可以和定子铁芯100连接，具体根据实际情况选择合适的方案。
参照图3、图5和图7所示，出线座210设有多个第一安装位211，多个第一端子300对应安装于多个第一安装位211，例如第一安装位211和第一端子300均设有两个或者三个，第一引出线110对应设有两根或者三根。第一端子300可以采用金属制成，例如铜或者铁等。每个第一端子300均包括出线部320和第一焊接部310，出线部320可以和第一焊接部310连接，或者第一端子300还包括第一安装部330，出线部320和第一焊接部310分别连接于第一安装部330。第一焊接部310用于焊接第一引出线110，多根第一引出线110对应焊接在多个第一焊接部310上，图7中网格状的线条表示焊接材料。焊接完成后将盖板220和出线座210连接，且盖板220能够覆盖多个第一安装位211，具有防护作用。而为了方便出线部320和电源线连接，因此出线部320穿出于盖板220，方便电源对绕组130供电。
可以理解的是，部分定子对于小型化和槽满率的要求较高，不利于定子出线。因此将出线座210设置在定子铁芯100的外部，从而方便绕组130的引出线引出至第一端子300的第一焊接部310，降低焊接难度，提高生产效率，且可以实现自动化生产，降低人工成本。而第一引出线110焊接于第一焊接部310，能够提高和第一端子300连接的稳定性，减少松动脱落的情况。
参照图3所示，本申请的实施例中，第一焊接部310的边沿设有第一折弯部311，第一折弯部311朝背离出线座210的方向延伸。例如，第一折弯部311可以是第一焊接部310的边沿向背离出线座210的方向折弯形成，也就是第一折弯部311和第一焊接部310为一体成型，制造简单且成本低。可以理解的是，第一引出线110通过锡焊的方式和第一焊接部310连接，当第一端子300采用铜制成时，焊锡和铜的附着性较好。而为了进一步提高焊锡和铜的附着性，因此在第一焊接部310的边沿设置第一折弯部311，焊锡能够附着在第一焊接部310和第一折弯部311上，焊锡能够更好的包裹第一引出线110，减少虚焊的情况，提高第一引出线110和第一端子300连接的稳定性和焊接质量。
继续参照图3所示，本申请的实施例中，第一折弯部311设于第一焊接部310沿第一引出线110的延伸方向的一端，例如第一折弯部311位于第一焊接部310朝向第一引出线110端部的一端。第一折弯部311还设有第一过线槽312，以使第一引出线110能够穿设于第一过线槽312。其中，第一过线槽312的高度大于或等于第一引出线110的外径，第一过线槽312的宽度大于或等于第一引出线110的外径，以使第一引出线110能够穿设于第一过线槽312。可以理解的是，第一过线槽312能够限制第一引出线110的位置，在焊接的过程中对第一引出线110具有一定的限位作用，有效减少第一引出线110出现错位、移动等现象，使第一引出线110能够准确的焊接在第一焊接部310上。
参照图5、图6和图7所示，本申请的实施例中，出线座210沿第一引出线110的延伸方向间隔设置有第一卡座212和第二卡座213，第一端子300位于第一卡座212和第二卡座213之间。当第一引出线110需要焊接时，第一引出线110可以依次卡接在第一卡座212、第一过线槽312和第二卡座213上，起到限位的作用，从而方便地将第一引出线110和第一焊接部310焊接，降低焊接难度，提高焊接效率。
参照图7所示，本申请的实施例中，出线座210沿第一引出线110的延伸方向设有避空槽214，避空槽214沿第一引出线110的延伸方向贯穿出线座210。可以理解的是，第一引出线110在焊接的阶段长度较长，因此将第一引出线110依次卡接在第一卡座212、第一过线槽312和第二卡座213上后可以穿过避空槽214，方便拉动第一引出线110使其和第一焊接部310的焊接位置贴合，方便后续的焊接工作。焊接完成后再对第一引出线110进行裁剪，例如裁剪至图7中所示的位置。因此，设置避空槽214可以降低焊接难度，提升焊接效率。
参照图3和图5所示，本申请的实施例中，第一安装位211设有安装槽，第一端子300的第一安装部330插设于安装槽内，安装简单方便。本申请的实施例中，第一安装部330设有凸起331，凸起331倾斜设置，以使第一安装部330和安装槽紧配合，有效避免第一端子300松动脱落，提高第一端子300安装的稳定性。
参照图4、图5和图7所示，本申请的实施例中，出线座210设有第二安装位216，绕组130还包括多根第二引出线120，定子组件1000还包括第二端子400，第二端子400安装在第二安装位216上。其中，第二端子400包括连接部410和多个第二焊接部420，多个第二焊接部420间隔设置在连接部410上，第二焊接部420用于焊接第二引出线120，多根第二引出线120一一对应焊接在多个第二焊接部420。例如，第二焊接部420设有三个，第二引出线120设有三根，三根第二引出线120对应设置在三个第二焊接部420。或者，第二焊接部420设有两个，第二引出线120设有两根，具体根据实际情况选择合适的方案。第二端子400可以采用金属制成，例如铜或者铁等材质。第二端子400的作用为将中性点的第二引出线120焊接在一起，因此多组绕组线之间采用的是星型接法。
需要说明的是，焊接过程中会产生热量，在焊接另外的第二引出线120时，会对之前焊接完成的第二引出线120造成影响，特别是对中间的第二引出线120影响较大。因此，多个第二焊接部420间隔设置，能够有效的降低热量的传递，减少焊接时相邻两个第二引出线120之间的互相影响，提高焊接质量，同时也能减少材料的使用。
参照图4所示，本申请的实施例中，第二焊接部420的边沿设有第二折弯部450，第二折弯部450朝背离出线座210的方向延伸。例如，第二折弯部450可以是第二焊接部420的边沿向背离出线座210的方向折弯形成，也就是第二折弯部450和第二焊接部420为一体成型，制造简单且成本低。可以理解的是，第二引出线120通过锡焊的方式和第二焊接部420连接，当第二端子400采用铜制成时，焊锡和铜的附着性较好。而为了进一步提高焊锡和铜的附着性，因此在第二焊接部420的边沿设置第二折弯部450，焊锡能够附着在第二焊接部420和第二折弯部450上，焊锡能够更好的包裹第二引出线120，减少虚焊的情况，提高第二引出线120和第二端子400连接的稳定性。
参照图4和图7所示，本申请的实施例中，第二折弯部450设于第二焊接部420沿第二引出线120的延伸方向的一端，例如第二折弯部450位于第二焊接部420朝向第二引出线120端部的一端。第二折弯部450还设有第二过线槽451，以使第二引出线120能够穿设于第二过线槽451。其中，第二过线槽451的高度大于或等于第二引出线120的外径，第二过线槽451的宽度大于或等于第二引出线120的外径，以使第二引出线120能够穿设于第二过线槽451。可以理解的是，第二过线槽451能够限制第二引出线120的位置，在焊接的过程中对第二引出线120具有一定的限位作用，有效减少第二引出线120的位置出现错位、移动等现象，保证第二引出线120能够准确的焊接在第二焊接部420上。
参照图4所示，本申请的实施例中，第二端子400还包括凸出部440和第二安装部430，第二安装部430连接于连接部410，第二安装位216同样设有安装槽，第二安装部430插设于第二安装槽内，以限制第二端子400的位置。而凸出部440和第二安装部430连接，且第二凸出部440朝向背离出线座210的方向延伸设置。可以理解的是，在安装第二端子400时，员工或者机器设备可以通过夹持凸出部440的方式方便地将第二端子400安装在第二安装位216上，而凸出部440和第二安装部430连接，便于安装第二端子400时使第二安装部430和安装槽对准，降低安装难度，提高安装效率。
参照图1和图8所示，本申请的实施例中，盖板220设有围边222和多个通孔221，例如通孔221设有三个。围边222环绕三个通孔221设置且形成有安装腔223，例如形成三个安装腔223。三个出线部320对应穿设于三个通孔221且位于三个安装腔223内。围边222起到防护出线部320的作用，有效降低出线部320出现磕碰、损伤等情况，且便于和电源线连接。
参照图2和图7所示，本申请的实施例中，出线座210远离绝缘框架200的一端设有定位槽215，盖板220远离绝缘框架200的一端设有挡板224，挡板224和定位槽215定位配合，以使出线座210、盖板220和挡板224之间形成塑封空间。因此，第一引出线110和第二引出线120均焊接完成后将盖板220和出线座210连接，在盖板220、挡板224和出线座210之间的塑封空间进行注塑封料，起到防护作用和进一步提高第一引出线110、第二引出线120和第一端子300、第二端子400连接的稳定性。同时，采用注塑封料的形式，无需人工打端子和穿管套，减少零部件，节约成本，且因此操作简单，能够实现自动化生产，提高生产效率。参照图8所示，最后可以对定子组件1000进行包塑，降低电机的温度和噪音。
本申请一种实施例的电机，包括以上实施例的定子组件1000。本申请实施例的电机，采用上述实施例的定子组件1000，出线座210设于绝缘框架200，且出线座210设有多个第一安装位211，多个第一端子300对应设于多个第一安装位211。第一端子300包括第一焊接部310和出线部320。绕组130绕设在绝缘框架200上，且绕组130还包括引出的多根第一引出线110。采用出线座210的设计，以及合理设计第一端子300的结构，方便将引出线引出至第一端子300，降低第一引出线110和第一焊接部310的焊接难度，提高生产效率。多根第一引出线110能够对应焊接于多个第一焊接部310，从而提高第一引出线110和端子连接的稳定性，不易松脱。而出线部320穿设于盖板220，方便出线部320和电源线连接。
由于电机采用了上述实施例的定子组件1000的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再赘述。
上面结合附图对本申请实施例作了详细说明，但是本申请不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本申请宗旨的前提下作出各种变化。
