Description of the Invention: [Technical Field] The present invention relates to a USB device having a pre-connected structure, and more particularly to a USB device that can quickly combine a USB connector and a circuit board without using a jig. [Prior Art] There are many computer peripherals available today, most of which use the Universal Serial Bus (USB) to connect with the host computer. Because USB itself is extremely convenient, USB has been widely used in plugs around the perimeter of various computers. In terms of structure, the USB device includes at least one circuit board and a USB connector, and the two are electrically connected; for example, for a flash drive, a wireless receiver, a wireless network card, etc. Most of the electrical connection methods are soldered to solder the terminals on the USB connector to the pad contacts at the corresponding positions on the board. Since the board's USB connector is partially overlapped at the end, the soldering operation is performed. If you want to ensure that the board and the USB connector are in a straight line, you can use the m疋 fixture to fix the two separately and then solder them. However, this method is not only costly, but the operation process is time-consuming and labor-intensive, and the efficiency is low. If the two boards are not fixed by the fixture first, the board and the USB connector are welded, and the board can be effectively tilted under the condition of being effectively fixed, thus affecting the yield of the product. SUMMARY OF THE INVENTION Therefore, the main object of the present invention is _ _ . ^ ^
