Patent ID: 7989719

Claim:
A universal serial bus (USB) interface comprising: a USB body comprising: a USB holding portion; a positive differential signal pin mounted to the USB holding portion, the positive differential signal pin comprising: a first terminal made of conductive material; and a second terminal made of conductive material, the second terminal spaced a distance to the first terminal; and a negative differential signal pin mounted to the USB holding portion; and a switch located adjacent to the USB body, comprising: a driving pole made of insulation material; and a conductive washer fixed to the driving pole, to contact with or depart from the first terminal and the second terminal of the positive differential signal pin; wherein when the driving pole is pressed, the conductive washer is driven to depart from the first terminal and the second terminal of the positive differential signal pin, an electrical connection between the first terminal and the second terminal of the positive differential signal pin is cut; when the driving pole is loosed, the conductive washer returns back, to contact the first terminal and the second terminal of the positive differential signal pin, and the first terminal and the second terminal of the positive differential signal pin are thus electrically connected.
