Description

Technical Field

[0001] The invention relates to an electric connector, and more particularly to a method for improving the crosstalk problem of the electric connector by utilizing the arrangement position of terminals. Background Art

[0002] Due to the development of various electronic products, different electronic products' external devices use electrical connectors with different transmission interfaces. General electrical connectors need to install drivers and restart before they can be used. Therefore, a hot-plug external transmission interface, Universal Serial Bus (USB), has been developed. It is a serial port bus standard for connecting computers and external devices, and also a technical specification for input and output interfaces. USB connectors have been widely used in electronic products such as computers and mobile devices. Currently, USB connectors have developed into USB3.0 connectors, which can support both USB2.0 and USB3.0 transmission interfaces and greatly improve signal transmission speed.

[0003] Figure 1 FIG. 1 is a schematic diagram showing a USB 3.0 connector soldered on a circuit board in the prior art. Figure 1 As shown, the prior art is to weld the welding parts 321', 411, 321, 511, 311, 511', 331', 421, 331 of a first differential signal negative terminal (SSTX-), a second ground terminal (GND), a first differential signal positive terminal (SSTX+), a third differential signal positive terminal (D+), a first ground terminal (GND), a third differential signal negative terminal (D-), a second differential signal negative terminal (SSRX-), a common power terminal (VBUS) and a second differential signal positive terminal (SSRX+) on a circuit board, so that the welding parts 321', 411, 321, 511, 311, 511', 331', 421, 331 of each terminal are arranged in a row. Since the terminal group of USB2.0 and the terminal group of USB3.0 are arranged in the same row, a very serious crosstalk interference problem is caused between the terminals.
