Electrical connector and method of manufacturing same

The present invention relates to an electrical connector and a method of fabricating the same, and more particularly to an electrical connector capable of improving signal transmission rate and a method of fabricating the same.

The Universal Serial Bus (USB) interface is a standard input/output interface that has been widely used in many electronic device designs. In 1994, seven world-renowned computer and communication companies, including Intel, Compaq, Digital, IBM, Microsoft, NEC, and Northern Telecom, jointly established the USB Association (USB-IF) to initially establish a USB interface specification. So far, the USB Association has released versions 1.0, 1.1 and 2.0.

The above USB 1.0, 1.1, and 2.0 versions support the following three transmission rates: (1), low-speed mode transmission rate of 1.5 megabits per second, mostly for keyboards and mice; (2), full-speed mode transmission rate of 12 megabits (3), high-speed mode transmission rate is 480 megabits per second.

With the development of the electronics industry, even the transmission speed of USB 2.0 can no longer meet the development requirements of some electronic industries. For example, in the case of transmitting audio or video, in order to ensure the quality of signal transmission, the transmission rate is often as high as 1G to 2G per Seconds (1G = 1000 megabits). Two other types of interfaces in the field of electrical connectors, such as PCI-E (transmission rate up to 2.5G per second) and SATA interface (transmission rate up to 1.5G to 3.0G per second), have significantly exceeded the USB 2.0 interface. .
