Problems solved by technology

[0002] At present, the existing USB connector does not have the electrostatic discharge protection function, but the electrostatic discharge protection part of the USB connector is directly designed on the system printed circuit board. This design will have the following disadvantages: First, every design and printing The circuit board needs to redesign the USB electrostatic discharge protection part; second, the protection performance of each design electrostatic discharge protection part is inconsistent; third, it is necessary to re-verify and debug the electrostatic discharge protection part of the USB connector after each design ; Fourth, after each design, the electrostatic discharge protection part of the debugging USB connector has different effects on electromagnetic interference.

Abstract

The invention discloses a universal serial bus (USB) connecting device and an electronic product. The USB connecting device comprises a printed circuit board. A static releasing protecting circuit which has the function of protecting static release is arranged on the printed circuit board. A static releasing circuit of the USB connecting device is not required to be designed time and again. The static releasing circuit of the USB connecting device can ensure uniformity of design. The static releasing circuit of the USB connecting device does not always need renewed debugging after being designed each time. Electromagnetic interference of the static releasing circuit of the USB connecting device is uniform after being designed each time.
