Problems solved by technology

However, due to long-term use, dust will enter the USB interface, causing changes in the impedance of the pins in the interface, and even short-circuiting the pins. Therefore, the output voltage of the USB interface will be unstable or rise sharply, and the device will be burned.

Abstract

The embodiment of the invention discloses a piece of electronic equipment which comprises a shell body, a USB interface and a control chip, wherein the USB interface is formed in the shell body; the control chip is disposed in the shell body and connected to an equipment identification pin in the USB interface; the control chip is used to detect a pin voltage of the equipment identification pin when the electronic equipment is connected to a USB power adapter via the USB interface; when the pin voltage satisfies a preset condition, electric connection between the USB interface and the USB power adapter will be cut off, so the electronic equipment could be protected. The embodiment of the invention also discloses a method for protecting the electronic equipment.

Description

technical field [0001] The invention relates to the application field of electronic equipment, in particular to a method for protecting electronic equipment and the electronic equipment. Background technique [0002] With the development of science and technology, more and more electronic devices have entered people's lives, such as smart phones, tablet computers, notebook computers, etc. These electronic devices provide great convenience to people's lives. [0003] At present, in the existing Universal Serial Bus (USB, Universal Serial Bus) power adapter, a device identification pin (ID Pin) is provided in the USB interface, and the power adapter and the device are connected by obtaining the voltage value of the ID Pin. access identification. However, due to long-term use, dust will enter the USB interface, causing changes in the impedance of the pins in the interface, and even short-circuiting the pins. Therefore, the output voltage of the USB interface will be unstable o...
