具体实施方式
本发明揭示了一种漆包线用自切割焊接端子组件，结合图1所示，包括一连接端子，所述连接端子设置有端子输入端1及端子输出端2。所述端子输入端1及端子输出端2分别用于信号的输入和输出。具体端子输出端2的朝向由与所述连接端子连接的设备所决定，所述端子输出端2的形状结构可以采用如图1所示的开设有中心孔的纺锤形或水滴形，并不局限于图1所示的位置。
所述端子输入端1与端子输出端2的连接处设置有焊料容纳槽6，所述焊料容纳槽6的两侧设置有压装侧翼3。所述端子输入端1上开设有用于漆包线进入的切口槽11，所述焊料容纳槽6内设置有焊料，且所述焊料容纳槽6的槽径与所述漆包线的线径相当。所述焊料的形式有多种，可以采用钎焊丝、悍膏等，若采用钎焊丝，在漆包线焊接时会以钎焊的形式，采用比母材熔点低的金属材料作钎料，将焊件和钎料加热到高于钎料熔点，低于母材熔化温度，利用液态钎料润湿母材，填充接头间隙并与母材相互扩散实现连接焊件的方法。此时，母材是指漆包线内的导体。从便利度考虑，优选的采用悍膏的形式。
所述切口槽11呈长条形设置，且所述切口槽11的槽口宽度小于所述漆包线7内的导体线径。所述切口槽11的上端内侧设置有用于 切划漆包线绝缘层的切刀4。切口槽的中部设置有用于进一步清除绝缘层的锯齿状刀片5。使用时，先将漆包线7从切口槽11的开口处压入，先经过切刀4将漆包线7的两端进行绝缘层的切开，然后继续往下压，经过锯齿状刀片5，对经过切开的绝缘层进行慢慢的清除剥离。为了提高去除绝缘层的效果，在下压同时，可以在经过锯齿状时转动漆包线。当然，也可以将切刀4的形状结构设置为S形或镰刀状，即在下压时开始对漆包线底部进行切除绝缘体。在一般切除完绝缘体的漆包线时，需要对漆包线进行焊接，为了能一步到位，所述焊料容纳槽6设置于所述切口槽11的正下方，即所述焊料容纳槽6与所述切口槽11共轴。漆包线继续下压时，完成切除绝缘体的部分进入到焊料容纳槽6内。由于焊料容纳槽6内设置有焊料，此时，对焊料容纳槽部分进行加热，即可完成焊接。
为了能更好的对漆包线下压的位置作限定，所述端子输入端1的底端为限位部，所述限位部与所述长条形切口槽11联通，且所述限位部截面呈圆形，所述限位部的弧面与所述漆包线外表面相切。所述焊料容纳槽与所述端子输入端的底部设置于同一高度上。
本发明还揭示了以上所述的漆包线用自切割焊接端子组件的成型方法，包括如下步骤，
S1、准备原料片材；
S2、将片材的上端作为端子输入端1，并在端子输入端1上加工开设形成用于漆包线进入的切口槽11；并将切口槽11的底部加工形成圆形；并在切刀的下部设置形成有锯齿状的刀片5。
S3、将片材的下端作为端子输出端2；
S4、将片材的两侧对称于圆形限位槽的位置加工焊料容纳槽6，焊料容纳槽形状向限位圆形槽位置倾斜导流，焊料容纳槽的两侧形成压装侧翼3；所述焊料容纳槽与所述切口槽11的圆形底部中心在同 一轴线上；
S5、对所述焊料容纳槽内填入焊料；
S6、对端子输出端进行结构成型以形成所需位置的端子输出端。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
