所述电连接部11与多个所述转接部13电性连接，临近每个所述转接部13对应设置有定位部14，所述定位部14能够在绕组引线与对应的所述转接部13固定连接前对搭接在所述转接部13上的绕组引线进行预定位。
在本实施例中，所述电连接部11包括护线凸台111和设置于所述护线凸台111的多个用于固定连接导线的穿线孔112，其中，所述电连接部11中的引出导线的焊接处在使用过程中存在发生断裂的情况，设置护线凸台111可形成包覆焊接处的结构，有利于避免导线焊接段发生脱落的情况；此外，所述穿线孔112的数量与电机的类型有关，比如电机为三相电机时，该穿线孔112的数量相应地为三个。
进一步地，在本实施例中，所述转接部13可为设置于所述本体1的通槽内的焊接盘，其中，所述焊接盘用于连接绕组引线的盘面与所述本体1的表面齐平或者凸出于所述本体1表面，同时焊接盘通过转接端子内部的导体与所述电连接部11连接，该内部的导体可以是以PCB为通电主体的结构，或是以冲压铜片为通电主体的结构。
在本实施例中，所述转接部13的数量与绕组引线的数量相适配，比如对于三相直流无刷电机，将存在6根绕组引线，假如在一个转接部13上可连接一根或者两根绕组引线，那么在所述本体1上将匹配这6根绕组引线至少设置3个转接部13；当然，对于多相电机来说，可以根据具体需要在所述本体1上设置不同数量的转接部13，在此不作限定。
在本实施例中，所述定位部14的作用在于绕组引线与所述转接板固定连接前的定位，其结构上需要在绕组引线与所述转接板固定连接后便于多余的绕组引线被剪除后易于脱落，出于此故，所述定位部14可采用定位卡槽的结构，当绕组引线从所述出线部12穿出并搭接在对应的转接部13上后，可将绕组引线嵌入所述定位卡槽，如此，在不需要外部定位结构(比如定位治具)辅助的情况下，绕组引线就都实现在转接端子上的准确定位，绕组引线能准确的搭接在转接部13的表面，方便进行自动化焊接。
在一些实施例中，所述定位卡槽可成形于所述本体1上，具体的，所述定位卡槽可由所述本体1的外沿朝所述转接部13内陷形成(如图2中定位部14即为所示的定位卡槽结构)。在一些实施例中，所述定位卡槽在所述本体1上可与所述转接部13间隔一定的距离，也可在所述本体1上径直延伸至与所述转接 板的边缘相接。在另一些实施例中，为保证该定位卡槽可有效固定绕组引线，可使该定位卡槽在所述本体1上的槽延伸方向与所述转接部13在所述本体1上的延伸方向设置成一定具有一定的夹角。
在另一些实施例中，所述定位卡槽可成形于设置于所述本体1的其他结构上，比如，所述本体1包括第一面，所述电连接部11和所述转接部13均设置于所述第一面上，所述第一面上临近所述转接部13的位置设置有凸起(图中未示出)，其中所述定位卡槽成型于所述凸起上，具体可由所述凸起远离所述第一面的端面朝所述第一面部分地内陷形成，或者由所述凸起与所述第一面交接的侧面部分地内陷形成。
在可选实施例中，所述定位卡槽的槽宽可进一步被配置成与绕组引线的宽度相适配，以提高对绕组引线进行定位的稳定性。
在可选实施例中，所述定位卡槽的形状可进一步地被设置为弧形或者“L”形，以降低绕组引线从所述定位卡槽中滑出的几率。
在可选实施例中，所述定位部14可设置在对应的所述转接部13的中间位置的一侧，当所述定位部14完成对所述绕组引线的定位后，使得绕组引线搭接在所述转接部13上的部分正好位于所述转接部13的中心位置，有利于后续进行诸如焊接等固定操作。
当然，本发明实施例中的定位部14还可采用除定位卡槽以外的其他设置于所述本体1上的定位结构，只需该定位结构在无需增加外部定位结构的前提下能够满足在绕组引线与所述转接板固定连接前可对绕组引线进行定位，并在绕组引线与所述转接板固定连接后便于多余的绕组引线被剪除后易于脱落即可，在此不做展开说明。
进一步地，在本实施例中，所述出线部12可为贯穿所述本体1中间位置的通孔，其中，在所述通孔的孔壁设置有供所述本体1与电机内部的绕组支架连接的固定连接部，基于所述固定连接部可实现转接端子与电机内部绕组支架的固定连接。
在可选实施例中，如图1和图2所示，所述固定连接部可为所述孔壁内陷 形成的槽结构121，在所述槽结构121上设置有卡接台122，所述卡接台122可与电机内部绕组支架上的卡扣结构实现固定连接，以限制所述转接端子在电机的轴向及周向上的运动，形成轴向和周向定位，防止转接端子与绕组引线的连接过程中出现转接端子相对于电机绕组相关结构发生位移的情况而影响连接效果。
在可选实施例中，所述孔壁还设置有容线槽123，容线槽123在收容绕组引线的同时，还对绕组引线的走线起到导向作用，在可选方案中，所述容线槽123的数量可与所述转接部13的数量保持一致。
当然，在另一些实施例中，所述出线部12也可以是设置在所述本体1外沿的凹槽，所述固定连接部也可以设置在所述本体1外沿的结构，在此不作限定。
在本发明上述实施例中，所述转接端子的本体1及其上的部分结构可采用注塑成型的方式形成。
在本发明上述实施例中，当绕组引线完成预定位后，即可通过外部焊接装置对绕组引线与转接部13的搭接处进行自动化焊接，完成焊接后，电机的绕组相关结构便与转接端子完成了完整的装备，成为装配电机的半成品，便于后续电机的批量自动化装配。
本发明实施例提供的转接端子与现有技术相比至少存在如下优点：
1、在转接端子的本体上所具有的转接结构、电路导通结构的基础上，还增加了绕组引线的定位结构，使得绕组引线无需利用外部的定位结构即可快捷地固定到转接端子上，提高了生产效率，也可简化外部的焊接治具，同时也可提高自动化焊接的可靠性和准确性。
2、在增加定位结构的基础上，还在转接端子的本体上增加了其与电机内部绕组的相关结构固定连接的固定结构，使得转接端子也能够更好地与电机内部绕组的相关结构固定，提高转接端子的稳定性，能够更加可靠、更加准确地锁定转接端子与绕组引线的相对位置关系，使得采用该转接端子的电机的组装和生产更加便捷，更加稳定可靠，自动化焊接良率更高。
参阅图3，本发明实施例提供还提供一种定子组装结构，其包括定子铁芯2、包覆在所述定子铁芯2上的绕组支架20和绕制在所述定子铁芯2的铁芯柱上的绕组22，以及上述的转接端子；
其中所述本体1与所述绕组支架20固定连接，所述绕组22的绕组引线221穿过所述出线部12并与相应的所述转接部13搭接后由所述定位部14进行预定位，所述定位部14对所述绕组引线221的定位方式可参考上述实施例中的相关描述，在此不做展开说明。
在可选实施例中，所述本体1与所述绕组支架20采用卡扣方式固定，如图3所示，并结合图1和图2，作为可选的实施方式，所述出线部12为贯穿所述本体1中间位置的通孔，与所述出线部12相对应的位置，所述绕组支架20上设置有与所述出线部12上的固定连接部的数量一致的卡扣结构201，当该固定连接部由槽结构121和其上的卡接台122组成时，该卡扣结构201与所述槽结构121上设置的卡接台122卡接，由此实现绕组支架20与转接端子的固定连接，限制所述转接端子在电机的轴向及周向上的运动，形成轴向和周向定位，防止转接端子与绕组引线221的连接过程中出现转接端子相对于定子铁芯2发生位移的情况而影响连接效果。
当然，所述本体1与所述绕组支架20的固定连接方式不限于卡扣方式，且所述本体1与所述绕组支架20的固定连接结构的设置位置也不限于上述实施例中采用的方式，所述出线部12也可以是设置在所述本体1外沿的凹槽，所述固定连接部也可以是设置在所述本体1外沿的结构，所述绕组支架20上的固定连接结构相应地也设置在所述定子铁芯2的外围。
根据本发明实施例提供的定子组装结构，其采用的转接端子通过在临近转接部13的位置设置定位部14，可无需借助外部结构即可在绕组引线221搭接在转接部13上后对绕组引线221进行预定位，定位后可直接进行诸如焊接的连接操作，有利于采用该转接端子的定子组装结构的批量自动化生产，生产效率能够有效提高。
本发明实施例还提供一种电机，其包括转子结构和上述的定子组装结构，结合图1至图3，所述定子铁芯2为带铁芯柱的环状结构，所述转子结构和所述定子铁芯2的环状结构配合设置。具体的，所述转子结构可设置于所述环状结构形成的空腔内部，本实施例中的电机可以是多相直流无刷电机。
根据本发明实施例提供的电机，由于其采用的定子组装结构中所采用的转接端子在临近转接部13的位置设置定位部14，可无需借助外部结构即可在绕组引线221搭接在转接部13上后对绕组引线221进行预定位，定位后可直接进行诸如焊接的连接操作，有利于定子组装结构的批量自动化生产，进而有利于采用该定子组装结构的电机的批量自动化生产，有利于提高生产效率。
