结合图3、图5至图8所示，所述第一本体11和第二本体12分别注塑成型在第一端子21和第二端子22周围，从而分别形成为第一端子组件和第二端子组件。所述第一端子21和第二端子22中每一导电端子2分别具有一固定于第一本体11或第二本体12的后侧部14内的固定部23、自固定部23向前延伸并暴露于第一本体11或第二本体12的前侧部15外 侧的对接部24和延伸出端子座1的焊脚25。所述后侧部14的后端形成与一电路板(未图示)相配合的安装面141，所述焊脚25自固定部23后端弯折延伸并与安装面141平行设置，从而供本发明电连接器100采用表面焊接方式焊接至电路板上。当然，所述焊脚25也可垂直于安装面141设置，从而采用插入焊接方式焊接至电路板上。
结合图2至图9所示，若干所述第一端子21和/或若干所述第二端子22中具有至少一接地端子g，所述接地端子g和金属屏蔽片3中至少一者上设置有朝另一者突伸并使两者相互抵接的抵接部20。所述绝缘本体13注塑成型在所述接地端子g和金属屏蔽片3的抵接部位外围，从而对所述抵接部20与金属屏蔽片3的抵接状态进行有效保持，防止两者抵接不紧密而无法达成有效地电性连接。所述绝缘本体13上形成有供加压机构(未图示)在注塑成型时抵持固定抵接部20、以保证接地端子g和金属屏蔽片3紧密接触的让位孔131。
在本实施方式中，所述第一端子21和第二端子22中均设置有接地端子g，并且还具有相邻接地端子g设置以传输高频信号的差分信号端子ds。所述抵接部20设置于接地端子g上，并具有朝向金属屏蔽片3方向倾斜延伸的延伸部201和自延伸部201末端平行于金属屏蔽片3延伸的导通部202。所述导通部202与金属屏蔽片3相抵接并且部分暴露于所述让位孔131中。
具体地，在本实施方式中，所述第一端子21和第二端子22与标准的USB Type C插座连接器中的两排导电端子的信号传输和排列方式相同，即所述接地端子g分布在第一端子21或第二端子22中的两侧，并且沿垂直舌板部102的方向对应设置；而进一步地，所述接地端子g上均进一步设置有用以与所述金属屏蔽片3相抵接的所述抵接部20，通过该种设置，可有效改善连接器频域参数的谐振点，进一步改善接地端子g旁侧的差分信号端子ds的串扰现象，保证本发明电连接器100的高频信号传输性能。当然，所述接地端子g与金属屏蔽片3的配合设置也适应于其他可进行高频信号传输的电连接器(未图示)中，并通过所述抵接部20和绝缘本体13的保持设计来有效改善该种电连接器的谐振点，保证其高频信号传输性能。
另外，在本实施方式中，因所述第一本体11和第二本体12的结构相同，且分别注塑成型在第一端子21和第二端子22外围，从而可使得本发明中所述第一端子组件和第二端子组件由同一套模具制成且结构完全相同，将第一端子组件和第二端子组件组装在一起时，所述第一端子21和第二端子22如前述为类型相同但反向排布。
在本实施方式中，为进一步保证连接的可靠性，进一步改善高频性能，所述抵接部20在所述接地端子g上设置有两处，具体为包括自所述接地端子g的对接部24末端延伸的第 一抵接部203、自所述接地端子g的固定部23侧向向外延伸的第二抵接部204。所述第一抵接部203的导通部202向前延伸出第一本体11或第二本体12，并且还设置有朝向金属屏蔽片3方向突伸并与金属屏蔽片3相抵接的凸包2021，以加强与金属屏蔽片3的抵接效果。第二抵接部204的导通部202侧向向外延伸出所述第一本体11或第二本体12。
所述金属屏蔽片3安装在所述第一本体11和第二本体12之间，并且所述金属屏蔽片3的形状大致对应第一本体11和第二本体12的相对侧表面的形状设计，以有效隔绝第一端子21和第二端子22，防止两者之间产生干扰。其中，所述金属屏蔽片3上设置有与第一本体11和第二本体12上的突柱16相对应设置的开口31，以通过突柱16与开口31的配合而将金属屏蔽片3稳固定位在第一本体11和第二本体12之间。
进一步地，所述金属屏蔽片3的前方两侧向外突伸出第一本体11和第二本体12，并在两侧缘前端形成用以与对接连接器相锁扣配合的锁扣部32；而在两侧缘内侧形成有穿孔34，以供绝缘本体13注塑成型时填充在穿孔34中，进一步加强金属屏蔽片3和绝缘本体13的固定效果。所述金属屏蔽片3的后方两侧向外延伸设置有与所述接地端子g的第二抵接部204相对设置的对接片33，所述第二抵接部204的导通部202与所述对接片33相抵接，并且部分暴露于所述让位孔131中。
另外，所述绝缘本体13是在第一端子组件、金属屏蔽片3和第二端子组件组装在一起后注塑成型在前述三者外围。在本实施方式中，所述绝缘本体13不仅成型在所述接地端子g与金属屏蔽片3的抵接部20外围，同时还形成在所述第一端子组件和第二端子组件中的后侧部15外围，并且在后侧部15外围呈台阶状设置，以与后侧部15共同形成所述端子座1的基部101，同时加强第一端子组件、金属屏蔽片3和第二端子组件的固定稳固性。
此外，本发明上述较佳实施方式中，因两排导电端子2中的所述接地端子g对称设置在金属屏蔽片3的两侧，从而直接在所述接地端子g上成型处所述抵接部20，以使两者之间能够导通连接。当然，在其他实施方式中，当两排导电端子2中的接地端子g非对称设置时，也可通过在所述金属屏蔽片3上朝向接地端子g方向突伸设置所述抵接部20来达成抵接效果，并在绝缘本体13上对应该金属屏蔽片3上突伸的抵接部来设置供加压机构抵紧固定的让位孔，同样也可达成本发明的目的。
如图1和图2所示，所述遮蔽壳体4整体呈椭圆型管状设置，并包覆在端子座1的外围。在本实施方式中，所述遮蔽壳体4后端两侧向外张开设置，以将导电端子2的焊脚25让开，从而方便焊接。
结合以上本发明电连接器100的描述可知，本发明还涉及所述电连接器的制造方法，其包括：
提供第一端子组件和第二端子组件，所述第一端子组件包括若干第一端子21和固定若干第一端子21的第一本体11，所述第二端子组件包括若干第二端子22和固定若干第二端子22的第二本体12，若干所述第一端子21和/或若干所述第二端子22中具有至少一接地端子g；
提供金属屏蔽片3，并将第一端子组件、金属屏蔽片3和第二端子组件组装在一起，使金属屏蔽片3设置于第一端子组件和第二端子组件之间，所述第一端子21和/或所述第二端子22中的所述接地端子g和金属屏蔽片3中至少一者上形成有朝另一者突伸并使两者相互抵接的抵接部20；
将第一端子组件、第二端子组件和金属屏蔽片3置于一注塑模具中，并采用加压机构在所述抵接部20位置处将接地端子g和金属屏蔽片3进行抵紧固定；
然后在所述接地端子g和金属屏蔽片3的抵接部位外围注塑成型一绝缘本体13，以保持接地端子g和金属屏蔽片3在抵接部20位置处的抵紧状态，所述绝缘本体13上形成有供加压机构在注塑成型时抵持固定抵接部20的让位孔131。
综上可知，本发明电连接器100及其制造方法不仅通过在所述接地端子g和金属屏蔽片3中至少一者上设置朝另一者突伸而使两者相互抵接的抵接部20，以有效改善连接器频域的谐振点，保证高频信号传输性能；而且，在通过加压机构将接地端子g和金属屏蔽片3在抵接部位进行抵紧固定的情况下，使绝缘本体13注塑成型在抵接部位外围，得以有效保持所述抵接部位的抵接状态。该种抵接端子g和金属屏蔽片3的抵紧固定方式无需焊接，制程简单、方便形成且固定稳固持久。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
