下面参考附图来详细描述根据本发明实施例的线框组件。
如图1至图9所示，根据本发明实施例的线框组件100，包括：线框10和接线片20。
具体而言，线框10上具有开口向上(即如图5中所示的箭头上所指示的方向)的插槽101。线框10的上表面上具有一端与插槽101连通的密封槽102。
接线片20包括本体201和位于本体201的上(即如图6所示的箭头上所指示的方向)边沿且左右(即如图6所示的箭头左右所指示的方向)间隔布置的第一引脚202和第二引脚203。本体201插接在插槽101内且第一引脚202和第二引脚203中的一个与密封槽102相配合。接线片20可以一体成形，例如一体冲压成形。
这里需要说明的是，电机绕线后，电机引线5需要与铝线绕组线头30连接，如果直接连接，铝线绕组线头30连接处密封保护就非常困难。为了实现电机引线5与铝线绕组线头30分离，本申请巧妙设计了一种接线片20，第一引脚202和第二引脚203中的一个与铝线绕组线头30连接(焊锡或浸锡)，第一引脚202和第二引脚203中的另一个与电机引线5连接。连接有铝线绕组线头30的引脚(如图2所示，为第一引脚202)折弯到密封槽102内后，然后在密封槽102内灌注密封胶40(如图4所示)，直至铝线绕组线头30完全密封为止。
根据本发明实施例的线框组件，接线片的第一引脚和第二引脚中的一个与铝线线头焊接后折弯并配合在密封槽内，然后对密封槽进行灌注密封胶等以将焊接有铝线线头的引脚覆盖，结构简单，可以对铝线焊点进行很好的密封保护。
如图5至图7所示，根据本发明的一个示例，插槽101内还具有定位凸楞103，本体201上具有开口向下(即如图6中所示的箭头下所指示的方向)且与定位凸楞103相适配的卡槽204。有利地，定位凸楞103沿竖直方向延伸。由此，当接线片20插接到插槽101内时，可以利用定位凸楞103和卡槽204的配合来进行定位，插接方便。
如图5所示，根据本发明的一个示例，插槽101的开口的中心线与密封槽102的中心 线正交。即，插槽101的开口于密封槽102构造成L形。由此，结构美观、安装方便。
如图6和图7所述，根据本发明的一个示例，第一引脚202的左(即如图6中所示的箭头左所指示的方向)表面与本体201的左表面平齐，第二引脚203的右(即如图6中所示的箭头右所指示的方向)表面与本体201的右表面平齐。有利地，第一引脚202的右侧的根部具有第一凹缺2021，第二引脚203的左侧的根部具有第二凹缺2031。由此，当第一引脚和第二引脚中的一个与铝线线头焊接后，便于该引脚折弯。
如图1至图8所示，根据本发明实施例的线框环组件110，包括：线框环本体111和至少一个接线片20。
线框环本体111上具有沿线框环本体111的周向间隔布置的多个线框10。多个线框10中的任一个具有开口向上的插槽101，该线框10的上表面上具有一端与插槽101连通的密封槽102。

关于多个线框10在线框环本体111上的组成方式不做特别限定，可以是多个线框10依次形成在线框环本体111上，也可以是多个线框10依次连接后构成线框环本体111。这对于本领域技术人员来说，是可以理解的。
接线片20的数量可以与多个线框10一一对应，接线片20的数量也可以少于多个线框10，接线片20的数量可以根据绕组接线的需要进行选择。
如图5至图7所示，根据本发明的一个示例，插槽101内还具有定位凸楞103，本体201上具有开口向下(即如图6中所示的箭头下所指示的方向)且与定位凸楞103相适配的卡槽204。有利地，定位凸楞103沿竖直方向延伸。由此，当接线片20插接到插槽101内时，可以利用定位凸楞103和卡槽204的配合来进行定位，插接方便。
如图5所示，根据本发明的一个示例，插槽101的开口的中心线与密封槽102的中心线正交。即，插槽101的开口于密封槽102构造成L形。由此，结构美观、安装方便。
如图6和图7所述，根据本发明的一个示例，第一引脚202的左(即如图6中所示的箭头左所指示的方向)表面与本体201的左表面平齐，第二引脚203的右即如图6中所示的箭头右所指示的方向)表面与本体201的右表面平齐。有利地，第一引脚202的右侧的根部具有第一凹缺2021，第二引脚203的左侧的根部具有第二凹缺2031。由此，当第一引脚和第二引脚中的一个与铝线线头焊接后，便于该引脚折弯。
如图9所示，根据本发明实施例的用于电机的定子组件1，包括：磁极120；和上述任一项所述的线框环组件110。线框环组件110设在磁极120的上表面和/或下表面上。

如图10所示，根据本发明的电机，包括上述的用于电机的定子组件1。更具体地，定子组件1制作完成后，压入后端盖总成4，再放入转子总成3，并与前端盖总成2扣铆或螺钉固定，电机引线5连接在定子组件1上。
定子组件1可以是整体式定子结构，包括N个集中绕组式磁极；也可以是分块式定子结构，由N个集中绕组式磁极拼装成整个定子总成；还可以是条形式定子结构，由N个集中绕组式磁极连成条形，弯转成整个定子总成。
在本发明的一个示例中，每个集中绕组式磁极上下两端面装有线框环组件110，接线片20插入相对应的线框10中，铝线绕组线头30缠绕在接线片20上。
电机绕线后，电机引线5需要与铝线绕组线头30连接，如果直接连接，铝线绕组线头30连接处密封保护就非常困难。为了实现电机引线5与铝线绕组线头30分离，本申请巧妙设计了一种接线片20，第一引脚202和第二引脚203中的一个与铝线绕组线头30连接(焊锡或浸锡)，第一引脚202和第二引脚203中的另一个与电机引线5连接。
同时在线框10上设计插槽101，密封槽102和定位凸楞103。
这样，绕线前根据绕组接线需要，在线框10相对应的插槽101中插入一定数量的接线片20。在插片过程中，通过卡槽204和定位凸楞103定位，连接有铝线绕组线头30的引脚与密封槽102对齐。集中式绕组电机定子，直接在磁极上绕线，绕线后铝线绕组线头30缠绕在第一引脚202上，然后进行去漆包线上漆膜、焊锡或浸锡，使铝线绕组线头20与接线片20连通。把焊锡或浸锡后的第一引脚202弯折到相对应的密封槽102内。
第一引脚202弯折到密封槽102内后，在密封槽102内灌注密封胶40，直至铝线绕组线头30完全密封为止。第一引脚202以及铝线绕组线头30完全被密封胶覆盖。电机引出线直接或通过接线板间接与第二引脚203连接，再对电机进行装配，形成完整的集中绕组式铝线电机。
根据本发明实施例的线框组件，可以对铝线绕组线头保护进行防呆，铝线绕组线头完全与空气隔绝，防止其氧化，保障密封一致性和电机可靠性，对铝线大批量运用在风扇电机上起到促进作用，尤其针对小线径的铝线电机效果更明显，降低了成本，有利于抢占市场份额。

在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
