Abstract: A universal serial bus (USB) cover connecting structure of an electronic product is provided, including a USB cover, covering a USB port of the electronic product, and disposed on a case of the electronic product. A first extending part and a second extending part are disposed on opposite ends of the USB cover, and a first gap and a second gap are formed between the first extending part, the second extending part, and sidewalls of the USB cover, so that while one of first and second extending parts is pressed, the other one of the first and second extending parts will be lifted, thereby forming a digging position for a finger to easily pull the USB cover out. Costs of molds and production are reduced due to removal of a groove.
