本实施例中，导电连接座100包括第一主输入端子110、第一电连接部140、第二主输入端子120、第二电连接部150、第三主输入端子130以及第三电连接部160。第一主输入端子110、第二主输入端子120以及第三主输入端子130用于对应获取三相电流。可以理解地，在其他实施例中，主输入端子和电连接部的数量可以根据情况设置，例如两相马达中，仅需提供两个主输入端子和两个电连接部。本文将以三相马达为例对本发明特征进行详细说明。
第一主输入端子110与第一电连接部140电连接，第一电连接部140用于与马达10的绕组200的第一端210电连接。具体地，本实施例中，第一电连接部140用于与四个不同绕组200的第一端210等电势连接，从而使第一电连接部140能够将电能传递至前述的四个绕组200。具体地，本实施例中，第一电连接部140与四个绕组200直接连接。
其他实施例中，第一电连接部140还可以与五个、六个或更多的绕组200进行直接连接，这里不做赘述。
参见图1以及图5，本实施例中，导电连接座100配置为使与其等电势连接的各绕组200相互并联。即每个绕组200的第一端210均电连接于第一电连接部140，每个绕组200的第二端220均电连接于一点（具体连接于下文中提到的第四电连接部170）。
本实施例中，相对于使与第一电连接部140直接连接的绕组200先与别的绕组200（未与第一电连接部140直接连接的绕组200）串联后再彼此并联的结构而言，为了保证每个绕组200分得的电压相同，本申请中的绕组200中流过的电流可以更小（现有技术中第一电连接部140连接的绕组200存在串联，电流相对更大），故卷绕成绕组200的导线的直径可以更小，使得单个绕组200体积更小，相邻两绕组200之间的间隔可以变大。上述方案中，一方面降低了相邻两绕组200接触从而短路的几率，提升了马达10的安全性能。另一方面，还增加了去除布置于相邻两绕组200之间的绝缘纸的可能性，从而能够降低马达10的物料成本以及加工成本。
第二主输入端子120与第二电连接部150电连接，第二电连接部150用于至少直接连接四个绕组200的第一端210，本实施例中，第二电连接部150直接连接四个绕组200的第一端210。第二主输入端子120将获取的电流传递至第二电连接部150，第二电连接部150将电流传递至与其连接的四个绕组200。
第三主输入端子130与第三电连接部160电连接，第三电连接部160用于至少直接连接四个绕组200的第一端210，本实施例中，第三电连接部160直接连接四个绕组200的第一端210。第三主输入端子130将获取的电流传递至第三电连接部160，第三电连接部160将电流传递至与其连接的四个绕组200。
本实施例中，导电连接座100还包括第四电连接部170，第四电连接部170电连接所有绕组200的第二端220。即每个绕组200的第二端220均电连接于第四电连接部170，所有绕组200的第一端210分别对应电连接于第一主输入端子110、第二主输入端子120或第三主输入端子130中的一者。从而马达定子的所有绕组200呈星形连接。
本实施例中，导电连接座100能够使与每个主输入端子连接的绕组200均呈单独并联连接，且呈星形连接，从而可以进一步地减小各绕组200之间流通的电流，使得各绕组200均能够采用直径更小的导线，降低了相邻两绕组200之间接触短路的几率，从而提升了马达10的安全性能。
本实施例中，第一主输入端子110、第二主输入端子120以第三主输入端子130均沿第一方向X（具体为马达10的轴向）延伸布置，第一主输入端子110、第二主输入端子120以及第三主输入端子130以第一轴线400（具体为马达10的转轴）为中心轴呈圆形阵列布置，且阵列角度为三百六十度。换句话说，以第一轴线400为中心轴，沿第一周向M，第一主输入端子110、第二主输入端子120以及第三主输入端子130两两之间的相隔角度均为一百二十度。该结构布置能够使得第一电连接部140、第二电连接部150以及第三电连接部160的周向最大尺寸变小，使第一电连接部140、第二电连接部150以及第三电连接部160加工时均可以具有较少的加工废料，降低了第一电连接部140、第二电连接部150以及第三电连接部160的加工成本。
可以理解地，其他实施例中，第一主输入端子110、第二主输入端子120以及第三主输入端子130也可以根据实际需求设计为其他排列角度，这里不做赘述。
具体地，本实施例中，参见图3-6，第一电连接部140包括第一分支141以及第二分支142，第一分支141与第二分支142分别电连接于第一主输入端子110的一端。第一分支141用于直接连接两个绕组200的第一端210，第二分支142用于直接连接另外两个绕组200的第一端210。该方案中，采用第一分支141以及第二分支142两个单独的零件来分别连接四个绕组200，使得第一电连接部140各零件的整体体积可以更小，相较于采用一个零件同时连接四个绕组200的结构而言，第一电连接部140加工时加工难度更低，加工废料更少，成本更小。其他实施例中，第一分支141还可以连接三个或更多的绕组200的第一端210，第二分支142亦可以连接三个或更多的绕组200的第一端210。

第二部分112一端连接第一部分111、另一端连接第一分支141靠近第一部分111的一端。第二部分112与第一分支141的连接方式可以为焊接。由于第一主输入端子110具有沿第一周向M延伸的第二部分112，可以减小第一分支141的周向长度，从而使得第一分支141的体积可以更小，降低了第一分支141的加工难度，且减小了第一分支141加工时的加工废料。
第三部分113一端连接第一部分111，另一端连接第二分支142靠近第一部分111的一端。第三部分113与第二分支142的连接方式可以为焊接。由于第一主输入端子110具有沿第二周向N延伸的第三部分113，可以减小第二分支142的周向长度，从而使得第二分支141的体积可以更小，降低了第二分支142的加工难度，且减小了第二分支142加工时的加工废料。
第二电连接部150包括第三分支151以及第四分支152，第三分支151沿绕第一轴线400的第一周向M延伸布置，第四分支152沿绕第一轴线400的第二周向N延伸布置。第二主输入端子120包括第四部分121、第五部分122以及第六部分123。第四部分121沿第一方向X延伸，第五部分122一端连接第四部分121沿第一方向X的一端，第五部分122的另一端连接第三分支151靠近第四部分121的一端。第六部分123一端连接第四部分121沿第一方向X的一端，第六部分123另一端连接第四分支152靠近第四部分121的一端。第五部分122以及第六部分123连接第四部分121的共同的一端，且第四部分121、第五部分122以及第六部分123一体弯折成型。第一主输入端子110的上述结构布置中，可以减小第三分支151以及第四分支152的周向长度，从而使第三分支151以及第四分支152的整体体积可以更小，降低了第三分支151以及第四分支152加工时的加工废料。
第三电连接部160包括第五分支161以及第六分支162，第五分支161沿绕第一轴线400的第一周向M延伸布置，第六分支162沿绕第一轴线400的第二周向N延伸布置。第三主输入端子130包括第七部分131、第八部分132以及第九部分133。第七部分131沿第一方向X延伸，第八部分132一端连接第七部分131沿第一方向X的一端，第八部分132的另一端连接第五分支161靠近第七部分131的一端。第九部分133一端连接第七部分131沿第一方向X的一端，第九部分133另一端连接第六分支162靠近第七部分131的一端。第八部分132以及第九部分133连接第七部分131的共同的一端，且第七部分131、第八部分132以及第九部分133一体弯折成型。第三主输入端子130的上述结构布置中，第五分支161以及第六分支162的整体体积可以更小，降低了第五分支161以及第六分支162加工时的加工废料。
本实施例中，第一分支141、第二分支142、第三分支151、第四分支152、第五分支161以及第六分支162均分别用于连接两个绕组200的第一端210。第一分支141、第二分支142、第三分支151、第四分支152、第五分支161以及第六分支162共同连接马达10的十二个绕组200的第一端210，第四电连接部170连接十二个绕组200的第二端220，使得十二个绕组200呈星形连接。

本实施例中，第一分支141、第六分支162以及第六部分123依次沿第一方向X层叠布置。从而降低了第一分支141、第六分支162以及第六部分123三者的整体占用空间。
具体地，参见图2、图5、图9以及图10，本实施例中，第一分支141包括用于与绕组200的第一端210电连接的第一连接端子1411，第四分支152包括用于与绕组200的第一端210电连接的第二连接端子1521，第六分支162包括用于与绕组200的第一端210电连接的第三连接端子1621。第二主输入端子120包括沿第一方向X延伸的第四部分121、第五部分122以及第六部分123，第四部分121沿第一方向X延伸布置，第五分支161绕第一周向M延伸布置且连接第三分支151，第六部分123绕第二周向N延伸布置且连接第四分支152。沿第一周向M，第一连接端子1411、第二连接端子1521以及第三连接端子1621均位于第一部分111以及第四部分121之间。上述结构布置使得与相邻的不同绕组200电连接的各连接端子能够对应相邻布置，便于各连接端子与绕组200进行电连接。
本实施例中，第一连接端子1411、第二连接端子1521以及第三连接端子1621沿第一周向M依次相邻分布。该结构布置使得第一连接端子1411、第二连接端子1521以及第三连接端子1621的布置顺序与布置方向同三者对应连接的三个绕组200的布置顺序以及布置方向相同，进一步方便了各连接端子与各绕组200之间的连接。优选地，本实施例中，第一连接端子1411、第二连接端子1521以及第三连接端子1621以第一轴线400为中心轴呈圆形阵列布置，且阵列角度为六十度。

由于第一分支141、第三分支151以及第五分支161的具体连接方式可以一样，故本实施例中第一分支141、第三分支151以及第五分支161的结构大小可以均相同。生产制造第一分支141、第三分支151以及第五分支161时，可以先制造同一个部件，然后将该部分安装于第一分支141的位置时该部件即为第一分支141；将该部件安装于第三分支151的位置时该部件即为第三分支151；将该部件安装于第五分支161的布置位置时该部件即为第五分支161。
由于第二分支142、第四分支152以及第六分支162的具体连接方式可以一样，故本实施例中第二分支142、第四分支152以及第六分支162的结构大小均可以相同。生产制造第二分支142、第四分支152以及第六分支162时，可以先制造同一个部件，然后将该部分安装于第二分支142的位置时该部件即为第二分支142；将该部件安装于第四分支152的位置时该部件即为第四分支152；将该部件安装于第六分支162的布置位置时该部件即为第六分支162。

其他实施例中，第四电连接部170还可以仅包括两个连接片或仅为一个连接片，这里不做赘述。相对于两个连接片或一个连接片的连接方式，设置四个连接片可以使得第四电连接部170的制程简单并节省原材料。
参见图11-16，本申请第二种实施例还提供了一种导电连接座100，该导电连接座100除了包括上述第一种实施例中的导电连接座100中的各部件外，还包括支撑部件190。为了便于描述，示例性地，以下将上述第一种实施例中的第一主输入端子110、第二主输入端子120、第三主输入端子130、第一电连接部140、第二电连接部150、第三电连接部160以及第四电连接部170组合成的整体称为母线总成101，母线总成101可以仅包括上述部件，也可以还包括除上述部件外的其他电连接部件。

进一步地，第一主输入端子110包括第一部分111，第一部分111设置于第一支撑臂1911与第二支撑臂1912之间，第一部分111设有第一凸起1111。第二支撑臂1912面向第一支撑臂1911的壁面设有沿平行于第一轴线400布置的第二滑槽1914，第二滑槽1914延伸至第二支撑臂1912背离环形部194的端部。第一部分111面向第二滑槽1914的壁面设有第二凸起1112，第二凸起1112伸入第二滑槽1914。第二滑槽1914与第二凸起1112的配合能够进一步使得第一主输入端子110不易沿垂直于第一轴线400的方向相对第一支撑部191位移。
第一主输入端子110还包括第二部分112以及第三部分113，第二部分112一端连接第一部分111靠近环形部194的一端，第二部分112的另一端沿绕第一轴线400的第一周向M延伸。第三部分113的一端连接第一部分111靠近环形部194的一端，第三部分113的另一端沿绕第一轴线400的第二周向N延伸。第二周向N与第一周向M相反。第二部分112包括U型片1121，U型片1121环绕第一支撑臂1911背离第一轴线400的外侧边布置，U型片1121的一端连接第一部分111，U型片1121的另一端环绕外侧边且贴合于第一支撑臂1911背离第二支撑臂1912的壁面。U型片1121的结构能够使得第一主输入端子110与第一支撑部191之间的限位更加牢靠，进一步防止第一主输入端子110与第一支撑部191之间产生沿垂直于第一轴线400方向的位移。
第一支撑部191还包括第一挡板1915，第一挡板1915连接于第二支撑臂1912背离第一轴线400的外侧边，第一挡板1915抵接U型片1121的背离第一支撑臂1911的壁面。第一挡板1915能够防止U型片1121沿背离第一轴线400的方向相对于第一支撑部191运动，从而提升对于第一主输入端子110的限位效果。
母线总成101还包括第四电连接部170，第四电连接部170用于连接马达10的所有绕组200的第二端220。环形部194一体注塑成型的过程中还连接第四电连接部170，使得支撑部件190对于母线总成101的固定效果更佳。其他实施例中，环形部194还可以不连接第四电连接部170，第四电连接部170通过粘接、卡接或胶接等方式与支撑部件190连接。
本实施例中，第四电连接部170设于环形部194靠近第一轴线400的内侧。其他实施例中，第四电连接部170还可以设置于环形部194背离第一轴线400的外侧，或者，第四电连接部170还可以与环形部194沿第一方向X层叠布置。
参见图13、图15以及图16，本实施例中，环形部194包括环形圈195以及连接于环形圈195的内侧的多个第三凸起199，各第三凸起199以第一轴线400为中心轴呈圆形阵列布置，各第三凸起199朝靠近第一轴线400的方向延伸，且各第三凸起199均连接第四电连接部170。沿平行于第一轴线400的方向观察，第四电连接部170的用于与绕组200连接的连接端子均位于两个相邻的第三凸起199之间。该方案中，一方面，能够节省支撑部件190的注塑量，另一方面，还能够方便绕组200的第二端220穿过两个相邻的第三凸起199而与第四电连接部170的连接端子电连接。
环形圈195包括与彼此相对的第一环形端壁1941以及第二环形端壁1942。第一主输入端子110设于环形圈195的第一环形端壁1941的一侧，各第三凸起199均沿平行于第一轴线400的方向伸出于第二环形端壁1942。各第三凸起199能够便于支撑部件190安装时与绕组200的绝缘架230内侧或绕组200的内侧抵接，从而便于导电连接座100的定位。
本实施例中，每个第三凸起199的背离第一轴线400的壁面呈弧面状，且沿远离环形圈195的方向，各弧面朝靠近第一轴线400的方向倾斜布置。该方案能够利于在导电连接座100安装时对导电连接座100进行安装导向。
本实施例中，参见图2、图11以及图16，环形圈195包括环绕第一轴线400布置的外周壁196。第一电连接部140、第二电连接部150以及第三电连接部160均包括与绕组200连接的连接端子(即第一连接端子1411、第二连接端子1521以及第三连接端子1621)，各连接端子均由外周壁196伸出环形圈195。该方案中，能够减小环形圈195的外径，从而减小环形圈195的注塑量。同时，相对于各连接端子由环形圈195的第一环形端壁1941而伸出环形圈195的方案而言，本实施例中第一环形端壁1941上布置的零件更少，结构更加简单，从而第一环形端壁1941上具有足够的空间来布置第一支撑部191、第二支撑部192以及第三支撑部193。本实施例中，第一电连接部140与第一主输入端子110连接的连接端子143同样由外周壁196伸出环形圈195。能够进一步减小环形圈195的外径，从而减小环形圈195的注塑量。
参见图15-16，支撑部件190还包括第一卡接部198，第一卡接部198连接于第一支撑部191，第一卡接部198沿平行于第一轴线400的方向朝背离第一主输入端子110的方向延伸。第一卡接部198用于卡接绕组200的绝缘架230，使得当导电连接座100的第一卡接部198与绕组200的绝缘架230卡接后，能够使得各绕组200的第一端210在第一方向X上正对第一电连接部140、第二电连接部150以及第三电连接部160的各个连接端子、还使得各绕组200的第二端220在第二方向上正对第四电连接部170的各个连接端子。
参见图1-图16以及图21，本申请还提供了一种用于马达10的定子组件11，该定子组件11包括上述任一项的导电连接座100、定子铁芯600、固定于定子铁芯600上的绝缘架230以及缠绕于所述绝缘架230上的多个绕组200，各绕组200固定于绝缘架230上，相邻两绕组200之间间隔相对布置。即相邻两绕组200之间直接间隔布置，之间未设置绝缘纸，从而降低了马达10的物料成本。
参见图17-21，本申请的还提供了一种马达10，该马达10包括图1-16的实施例中的定子组件11、转子组件500以及壳体300。各绕组200固定于绝缘架230，每个绕组200均分别包括与母线总成101电连接的第一端210以及第二端220。
绝缘架230具有第二卡接部231，支撑部件190的第一卡接部198与绝缘架230的第二卡接部231卡接后，使得各绕组200的第一端210在第一方向X上正对第一电连接部140、第二电连接部150以及第三电连接部160的各个连接端子、还使得各绕组200的第二端220在第二方向上正对第四电连接部170的各个连接端子。
马达10的绝缘架230、导电连接座100以及绕组200均设置于壳体300内，壳体300包括端盖310，端盖310设有开孔311，第一主输入端子110以及第一支撑部191均由开孔311而伸出壳体300的内腔。具体地，端盖310包括三个开孔311，第一主输入端子110以及第一支撑部191均由第一个开孔311伸出壳体300的内腔，第二主输入端子120以及第二支撑部192由第二个开孔311伸出壳体300的内腔，第三主输入端子130以及第三支撑部193均由第三个开孔311伸出壳体300的内腔。
