本实施例中，第一接触件由一块金属板经过裁剪、折弯形成，其中第二突出部203是通过卷圆方式形成的圆形结构，并与第一连接部201通过过渡段204连接。
如图9、图10、图11所示，是第一接触件可采用的几种可替换的变形结构。
第二接触件包括用于与绝缘基座100连接的第二连接部205、设置在第二连接部205两端且位于第二连接部205同一侧的第三突出部206和设置在第二连接部205中间的第四突出部207，当所述第二连接部205折弯成“U”型结构后，设置在第二连接部205两端的第三突出部206构成公接触端一13，第四突出部207折弯成“U”型结构并与绝缘基座100上的安装槽111共同构成母接触端一 14；第二连接部205还设置有若干第五突出部208，若干第五突出部208与第四突出部207分别位于第二连接部205的两侧。第五突出部208用于连接PCB板，如图12、图13、图14所示，是第五突出部208与PCB板采用不同的连接形式时的具体结构，其中，图12是穿孔式连接时的形式，图13是压接式连接时的形式，图14是表贴式连接时的形式。
本发明通过设置完全相同的两个子连接器，每个子连接器包括绝缘基座和安装在绝缘基座上用于供电和/或传输信号的接触件，绝缘基座上设置公连接件和母连接件；当将其中一个子连接器绕设定的旋转轴旋转一定的角度后，其公连接件与另一子连接器上对应的母连接件实现互插连接，其接触件与另一子连接器上对应的接触件实现电连接；减少了连接器的型号和类别，结构简单，精简了物料，实现了连接器的自我互插、低矮化和小型化，提高了PCB板间的装配效率。

本实施例中，公连接件一301是带有定位板3011的圆柱体，母连接件一302是带有定位槽3021的圆柱形孔。两个子连接器上的公连接件一301与母连接件一302相互配合互插连接，起导向定位作用，实现两个子连接器上的接触件的正确对接。
本实施例中，接触件包括第三接触件和第四接触件，绝缘基座100上设有用于分别安装第三接触件和第四接触件的呈“U”型槽结构的公接触端二15和与公接触端二15相匹配的母接触端二16。
本实施例中，第三接触件包括用于与绝缘基座100连接的第三连接部401，连接在第三连接部401上的第六突出部402和第七突出部403，其中，第六突出部402的自由端设有弧形结构4021，形成弹性结构，当两个子连接器在互插连接后，两个子连接器上的第三接触件的弧形结构4021相互挤压，形成可靠连接。第七突出部403用于连接PCB板。
本实施例中，第四接触件可视为三个第三接触件的并联设计。
