但随着所需进行传输的档案容量日渐增大，USB2.0的传输速度因受限于控制晶片及种种因素而开始不能满足使用时的需求，也因此促进了新一代USB3.0的推出，USB3.0除了维持既往的结构与随插即用的特色，更将应用领域扩及到个人电脑、消费电子商品及移动装置的同步即时传输中，其传输速度更为USB2.0的10倍，并且具有低功耗的优点。
目前的USB3.0电连接器虽然具有现有USB2.0电连接器的基础结构，但是因为利用添加一组端子来提升传输速度也使得其结构更为复杂。现有的USB3.0电连接器主要包括有两组端子、一绝缘本体和一金属外壳，该两组端子均通过冲压的方式成型，且该两组端子系直接通过镶嵌成型（molding）或插装的方式固定于绝缘本体上的，并利用金属外壳包覆住绝缘本体。然而，该种通过镶嵌成型（molding）直接将两组端子固定于绝缘本体上的方式不能保证产品的组装质量，容易使得各端子之间出现短路现象，造成不良品的产生，给企业和用户带来不便；而该种通过插装直接将各端子固定于绝缘本体上的方式使得组装较为不便，产品组装效率低，而且同样不能保证产品组装质量。另外，由于现有之USB3.0电连接器的绝缘本体上组装的端子数目增多，使得现有之USB3.0电连接器的绝缘本体强度不足，容易受外力破坏，给用户带来诸多不便。

具体实施方式
请参照图1至图5所示，其显示出了本发明之第一较佳实施例的具体结构，包括有一绝缘本体10、一印刷电路板20、五个附加端子30、四根USB2.0端子40、一固定座50和一金属外壳60。
以下将详细说明电连接器各元件的结构特点，再说明各元件的组装方式。而如果有描述到方向（上、下、左、右、前及后）时，是以图3所示的电连接器结构为参考描述，并以图中双箭头指示的方向为前侧面，但电连接器的实际使用方向并不局限于此。
其中，该绝缘本体10包括有基座11及基座11前端的舌板12，该基座11呈方形状，该舌板12于基座11的前表面上部向前延伸出，本实施例中的绝缘本体10为一体成型结构。该基座11上对应USB2.0端子40横向并排设置有供USB2.0端子40头部通过并同时用于固定USB2.0端子40的端子通道111，本实施例中设有四个端子通道111，但端子通道111的数量局限于四个，也可以系一个大的通道，不以为限。该基座11后端设有插槽121，该插槽121向前延伸至舌板12前端，该插槽121用于收纳印刷电路板20。另外，该舌板12的上对应USB2.0端子40横向并排设置有第一通槽122，本实施例中具有四个第一通槽122，每一个第一通槽122均纵向延伸，为前述对应的USB2.0端子40提供变形空间，当然第一通槽122的数量也可以系一个，不以为限。
该印刷电路板20的下表面前端缘横向并排设置有五个金手指21，对应该印刷电路板20的后端横向并排设置有五个焊接位22，每一焊接位22呈一通孔形状以用于插接的方式焊接，当然也可以平贴的方式来焊接，该五个焊接位22分别通过印刷电路板20上的布线23与前述对应的金手指21电连接。该印刷电路板20插装固定于前述插槽121中，该五个金手指21均露出舌板12的下表面，用于与外部插头接触。以及，该印刷电路板20的表面上对应前述第一通槽122横向并排设置有四个第二通槽24，当然该印刷电路板20上亦可设置一个大的通槽，每一第二通槽24均纵向延伸，该第二通槽24与前述第一通槽122彼此正对配合为USB2.0端子40提供变形空间。
该五个附加端子30中包括有两对差分信号端子和一接地端子，该两对差分信号端子用于传输USB3.0信号，提高信号传输效率。每一附加端子30均具有一连接端31和一焊接端32，该连接端31呈一钩状，连接端31由上往下勾住前述对应的焊接位22并与对应的焊接位22焊接固定电连接。该焊接端32向下伸出基座11外，用于与外部电路板焊接电连接。
该四根USB2.0端子40分别对应插装固定于前述端子通道111上，每一根USB2.0端子40包括有一体成型连接的弹性接触部41、固定部42和焊接部43。该弹性接触部41向下露出前述对应的第一通槽122外，该弹性接触部41与前述金手指21均露出舌板12的下表面，且该弹性接触部41位于前述金手指21的后端，该弹性接触部41用于与外部插头接触；该固定部42与端子通道111干涉配合而固定于基座11上；该焊接部43向下伸出基座11外，用于与外部电路板焊接电连接。
该固定座50由下往上插装固定于基座11的后端，且该固定座50抵于前述印刷电路板20的后端面上，防止印刷电路板20向后松动，该固定座50上对应前述附加端子30的焊接端32和USB2.0端子40的焊接部43设置有复数个通孔51，该附加端子30的焊接端32和USB2.0端子40的焊接部43向下穿过对应的通孔51，该固定座50用于对附加端子30的焊接端32和USB2.0端子40的焊接部43进行更好地固定，该附加端子30的焊接端32和USB2.0端子40的焊接部43排成至少两排伸出固定座50外，以便将附加端子30的焊接端32和USB2.0端子40的焊接部43很好地焊接到外部电路板上。
该固定座50系针对上述卧式结构的连接器设置的，而对于竖向连接器产品中，由于所有端子的焊接端可不需弯折再进一步去固定，故就可以不需要固定座50，由铁壳上折弯出一个折弯扣片取代固定座50来固定于印刷电路板，然后将连接器竖向插入焊接至外部的电路板中。此结构也同样可适应于第二实施例中。
该金属外壳60包覆住前述绝缘本体10，用于防止电磁干扰，该金属外壳60包括有主体61和后盖62。该主体61由顶板、底板以及两连接顶板和底板之间的侧板组成，该顶板、底板和两侧板围合形成一中空的腔体601；该后盖62于顶板的后端面向下折弯并封盖住该腔体601的后端开口，前述各附加端子30的焊接端32和USB2.0端子40的焊接部43均伸出金属外壳60；以及，该金属外壳60的两侧板分别延伸出有固定脚63，该固定脚63用于将金属外壳60焊接固定于外部电路板上。
详述本实施例的组装过程如下：
如图3所示，首先，使四根USB2.0端子40的弹性接触部41穿过对应的端子通道111并向下露出对应的的第一通槽122外，通过对应的固定部42与对应的端子通道111的壁面干涉配合而将对应的USB2.0端子40固定于绝缘本体10上，当然亦可通过镶嵌成型的方式（molding）设置于绝缘本体10上，并使各USB2.0端子40的焊接部43向下伸出基座11外。
接着，将五个附加端子30的各连接端31由上往下插入印刷电路板20上对应的焊接位22中，并与对应的焊接位22焊接固定电连接。
然后，将印刷电路板20的前端从插槽121的后端开口插入，使得印刷电路板20固定于绝缘本体10的舌板12中，并使各附加端子30的焊接端向下伸出基座11外，同时，其上的五个金手指21均露出舌板12的下表面，用于与外部插头接触。
接着，将固定座50由下往上插装固定于基座11的后端，并利用固定座50抵住印刷电路板20，防止印刷电路板20向后松动，同时使得前述各USB2.0端子40的焊接部43和各附加端子30的焊接端32穿过固定座50之对应通孔51而向下伸出。
最后，将绝缘本体10的前端由金属外壳60之主体61的后端开口插入，使得绝缘本体10固定于绝缘本体10的腔体601中，并使后盖62向下折弯将腔体601的后端开口封盖住，如图1所示，该金属外壳60包覆住绝缘本体10，各USB2.0端子40的焊接部43和各附加端子30的焊接端32均伸出金属外壳60。
使用时，只需通过固定脚63将电连接器固定于外部电路板上，将各USB2.0端子40的焊接部43和各附加端子30的焊接端32分别焊接到外部电路板上电连接即可。
