【技术领域】【Technical field】

本发明涉及一种电连接器，尤其涉及一种用以与不同插头对接的电连接器。The present invention relates to an electrical connector, in particular to an electrical connector used for docking with different plugs.

通用串行总线(Universal Serial Bus，USB)连接器广泛运用于各种电子设备上，例如电脑主机、移动硬盘、数码相机、打印机等，USB标准化团体(USBImplementers Forum，简称USBIF)先后公布了两个版本的USB标准：USB 1.1和与USB 1.1兼容的USB 2.0，USB 1.1的最高数据传输率为12Mbps(兆字节/秒)，USB2.0则提高到480Mbps。USB 2.0标准定义了两种插座连接器：A型和B型，均设有四根端子。其中，A型插座连接器的四根端子成排设置，依次为电源端子、一对差分信号端子、接地端子。目前，USB 2.0A型插座连接器的相关专利，可参阅美国专利公告第5,779,489号、第5,725,386号及第6,139,350号。该等专利所揭示的USB 2.0A型插座连接器包括设有舌板的绝缘本体，安装在舌板上的四根端子及包覆在端子及绝缘本体外围的金属遮蔽壳体。然而，为了更快的在电子设备之间进行资料传输，仅仅安装四根端子的USB 2.0插座连接器无法满足用户的需求。Universal Serial Bus (USB) connectors are widely used in various electronic devices, such as computer hosts, mobile hard disks, digital cameras, printers, etc. Version of the USB standard: USB 1.1 and USB 2.0 compatible with USB 1.1, the highest data transfer rate of USB 1.1 is 12Mbps (megabytes per second), and USB2.0 is increased to 480Mbps. The USB 2.0 standard defines two socket connectors: Type A and Type B, each with four terminals. Among them, the four terminals of the A-type socket connector are arranged in a row, which are power terminals, a pair of differential signal terminals, and ground terminals in sequence.
