Description

外接电源线与温控器的连接方法及其连接结构和电机 技术领域：
本发明涉及一种外接电源线与温控器的连接方法及其连接结构和电机，属于电机技术领域。
背景技术：
通常，在电机的定子绕组A上需要安装温度保护装置B，温度保护装置B的两个引脚B1分别与定子绕组A以及外接的电源线C连接。采用这种连接方式的温度保护装置的目的是在电机异常过载的情况下实现保护，防止意外事故的发生。在电机行业内，温度保护装置的引脚与外接的电源线的连接方式主要包括以下两种：
连接方式一(如图1所示)：温度保护装置B的引脚B1与外接的电源线C并排在一起，温度保护装置B的引脚B1的端部剥胶皮后裸露的线芯一与电源线C端部剥胶皮后裸露的线芯二相互缠绕并焊接在一起，最后在线芯一和线芯二的连接部位外面套装绝缘套管D。此种连接方式线芯一和线芯二的连接部位较为规则，线芯一和线芯二的连接部位不会对绝缘套管D以及定子绕组A造成损伤，但是，引脚、外接的电源线会在温度保护装置周边局部堆积，定子绕组整形时局部的定子绕组受压严重，容易损伤定子绕组的绝缘层；
连接方式二(如图2和图3所示)：温度保护装置B的引脚B1的端部剥胶皮后裸露的线芯一与电源线C端部剥胶皮后裸露的线芯二相互缠绕并焊接在一起，然后把温度保护装置B的引脚B1与外接的电源线C相互拉直，线芯一和线芯二的连接部位E就会与温度保护装置B的引脚B1或者外接电源线C的胶皮部分C1并排在一起，在线芯一和线芯二的连接部位E外面套装有绝缘套管D。连接方式二相比于连接方式一，温度保护装置的引脚分布较为均匀，不存在引脚、外接的电源线局部堆积的现象，但是此种连接方式线芯一和线芯二的连接部位十分不规则，连接部位的尖角容易对绝缘套管以及定子绕组造成损伤。
无论是连接方式一还是连接方式二，都无法同时满足连接部位规则以及引 脚、外接的电源线分布均匀的连接要求，两种连接方式都存在对绝缘套筒或者定子绕组的绝缘层的损伤隐患。

上述所述的线芯一的长度至少是线芯二的长度的两倍，折弯并排部设置在线芯一上。
上述所述的线芯二的长度至少是线芯一的长度的两倍，折弯并排部设置在线芯二上。
上述所述的线芯一和线芯二的端部对齐后再相互缠绕并焊接在一起。
上述所述的在线芯一和线芯二的端部对齐之前，预先在电源线上套入绝缘套管，在把温控器的引脚与外接的电源线相互拉直之后，再把绝缘套管套在折弯并排部与焊接公共部外面。

具体实施方式：
下面通过具体实施例并结合附图对本发明作进一步详细的描述。
实施例一：如图4和图5所示，本实施例是一种外接电源线与温控器的连接方法，温控器1上设置有两个引脚，其中一个引脚12用于与电机定子绕组上的铝漆包线电连接，另一个引脚11用于与外接的电源线2电连接，引脚11的端部是裸露的线芯一110，外接的电源线2的端部是裸露的线芯二21。
如图4所示，本实施例中优选的，线芯二21的长度大约是线芯一110的长度的两倍。在电源线2上套入绝缘套管5，线芯一110和线芯二21的端部对齐后再相互缠绕并锡焊在一起，线芯一110和线芯二21的前端部分形成焊接公共部3，线芯一110和线芯二21的端部对齐后再相互缠绕有利于提高采用浸锡焊接的操作效率，同时可以保证线芯一110和线芯二21的连接可靠。之后再把温控器1的引脚11与外接的电源线2相互拉直，所述的相互拉直是指通过外力把线芯一110和线芯二21朝相反的方向拉直，此时线芯二21的后端部分形成折弯并排部4，折弯并排部4与焊接公共部3并排在一起，最后把套在电 源线2上的绝缘套管5拉到折弯并排部4和焊接公共部3的外面，如图5所示。此连接方法操作简单、方便，外接电源线与温控器引脚的焊接公共部规则，焊接公共部不会对绝缘套管以及定子绕组造成损伤，而且以及外接的电源线、温控器的引脚均匀分布，不会在某个部位产生堆积的现象，利于定子绕组整形，降低定子绕组受损的风险，整体的说，产品的质量和可靠性都得到了稳步的提升。
以上实施例为本发明的较佳实施方式，但本发明的实施方式不限于此，其他任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均为等效的置换方式，都包含在本发明的保护范围之内。
例如，在本实施例中优选的线芯二21的长度大约是线芯一110的长度的两倍，但是对于本领域的技术人员容易联想到线芯一110的长度大约是线芯二21的长度的两倍或者其他的长度关系，对于这种未背离本发明的精神实质与原理下所作的改变，应该包含在本发明的保护范围之内。
实施例二：如图6和图7所示，本实施例是一种外接电源线与温控器的连接结构，温控器1上设置有两个引脚，其中一个引脚12用于与电机定子绕组上的铝漆包线电连接，另一个引脚11用于与外接的电源线2电连接，引脚11的端部是裸露的线芯一110，外接的电源线2的端部是裸露的线芯二21，线芯一110的长度大约等于线芯二21的长度的两倍，线芯一110的前端部分和线芯二21相互缠绕并焊接在一起形成焊接公共部3，线芯一110上设置有折弯并排部4，折弯并排部4与焊接公共部3并排在一起，在折弯并排部4与焊接公共部3外面套有绝缘套管5。
实施例三：如图4、图5、图6、图7和图8所示，本实施例是一种电机，包括转轴6、转子组件7、定子组件8、外壳组件9和温控器1，转子组件7安装在转轴6上，定子组件8和外壳组件9安装在转子组件7外面，转轴6两端支承在外壳组件9的轴承上，所述的定子组件8包括定子铁芯81和定子绕组82，定子绕组82卷绕安装在定子铁芯81上，温控器1安装在定子组件8上， 温控器1上设置有两个引脚，其中一个引脚12用于与电机定子绕组82上的铝漆包线电连接，另一个引脚11用于与外接的电源线2电连接，引脚11的端部是裸露的线芯一110，外接的电源线2的端部是裸露的线芯二21，线芯二21的长度大约是线芯一110的长度的两倍。如图4所示，在电源线2上套入绝缘套管5，线芯一110和线芯二21的端部对齐后再相互缠绕并锡焊在一起，线芯一110和线芯二21的前端部分形成焊接公共部3，线芯一110和线芯二21的端部对齐后再相互缠绕有利于提高采用浸锡焊接的操作效率，同时可以保证线芯一110和线芯二21的连接可靠。之后再把温控器1的引脚11与外接的电源线2相互拉直，所述的相互拉直是指通过外力把线芯一110和线芯二21朝相反的方向拉直，此时线芯二21的后端部分形成折弯并排部4，折弯并排部4与焊接公共部3并排在一起，最后把套在电源线2上的绝缘套管5拉到折弯并排部4和焊接公共部3的外面，如图5所示。
以上实施例为本发明的较佳实施方式，但本发明的实施方式不限于此，其他任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均为等效的置换方式，都包含在本发明的保护范围之内。
