Abstract
Disclosed is a rotary USB interface device, which includes: a USB module (), a PCB, a rotary shaft () connecting the USB module and the PCB, a conductive layer () connected with the rotary shaft, and an insulation layer () provided between a grounding layer () on the PCB and the conductive layer. The USB module contains a first ground wire, which forms a first grounding path of the USB module, together with the rotary shaft and the conductive layer. The grounding layer on the PCB forms a second grounding path. The first grounding path is separated from the second grounding path by virtue of the insulation layer, i.e. the grounding path of the PCB is separated from the grounding path of the USB module. Thus, an open circuit voltage is formed, the voltage difference is maintained stable, the overall device obtains a stable grounding signal, the grounding performance is enhanced and the transmitting/receiving performance of the device is improved.
