Abstract: The present invention discloses a USB connector, comprising: a USB shell, an insulation spacer, metal sheets with metal weld legs respectively. The metal sheets are installed on the insulation spacer, the metal sheets are configured to be connected to a USB interface of a personal computer, the metal weld legs are connected to a printed circuit board within an external product, and the insulation spacer is fixed in the USB shell; the metal sheets comprise one ground pin, two signal pins and one power supply pin, wherein the ground pin is configured with an extending resilient metal sheet contacted with the USB shell. Widths of the metal sheets and the metal weld legs are widen and thicknesses of the metal sheets and the insulation spacer are thicken, so that the USB connector and the USB interface of the computer are contacted sufficiently, enhancing the ground effect of the USB connector.
