Problems solved by technology

[0002] Electronic equipment is usually equipped with a power interface, which can receive power from the power supply equipment. However, the quality of the power supply equipment currently on the market is uneven, which may cause the electronic equipment to fail to supply power during peak power consumption, which may cause the electronic equipment to automatically shutdown problem
[0003] On the other hand, due to the small size of electronic equipment, the size of some power interfaces has been reduced again and again. During the process of plugging and unplugging, problems such as short circuits may occur between multiple pins in the power interface. At this time, If the power supply device continues to supply power through the power interface, it may cause a short circuit of the power supply and damage the electronic device
