Technical Problem
[0004]申请人在对上述防水简易注塑成型Type-C连接器制作过程中发现以下问题：首先，上述Type-C连接器是采用一体成型的方式将外绝缘套一体包裹金属壳外部，这样要求金属壳为无缝壳，而上述的金属壳采用包圆卡扣的方式成型，其之间形成有接缝，以致在金属壳外部注塑成型外绝缘套时，胶料存在透过接缝进入金属壳内部的现象，需要后期清理，增加工序，影响生产效率；另外，结合上述专利的附图2和图4可以看出，上述绝缘座未能一体包裹定位上端子的第一引脚部根部和下端子的第二引脚部根部，以致上端子的第一引脚部和下端子的第二引脚部不够稳定，其易变形，影响产品质量，且该上端子的第一引脚部和下端子的第二引脚部中的非焊接部分穿过外绝缘套的凹槽伸出于外绝缘套外，其也无固定，以致在成品连接器与PCB板通过IR(红外线回流焊)制程后，极大可能发生容易热变形胶与端子拉扯，引发平面度不良，进而影响焊接质量
Benefits of technology
[0018]1、所述绝缘座后端下侧成型有水平延伸的尾端部，该尾端部一体包裹第一SMT脚的根部和第二SMT脚的根部，以致第一SMT脚和第二SMT脚稳定伸出于绝缘座外，其装配结构稳定，且不易变形，提高产品质量，后期整个连接器与PCB板通过IR(红外线回流焊)制程后，不会发生容易热变形胶与端子拉扯，引发平面度不良的问题，进而保证焊接质量。
