The USB (Universal Serial Bus, Universal Serial Bus) connector is a connector widely used in various electronic information products and mobile communication devices. Storage devices such as common mobile hard disks are USB interfaces. As the products become thinner and smaller, the connector types of USB connectors have gradually developed into Mini-USB and Micro-USB. Most of the USB connectors on mobile hard disks are standard A-type connectors. In recent years, mobile devices such as mobile phones or tablet computers mostly use Micro B-type connectors. Therefore, mobile hard disks cannot be directly plugged into mobile phones or tablet computers for memory expansion. Instead, the standard A-type connector of the mobile hard disk must be changed to Micro B-type.

The structure of the existing Mirco B-type USB connector is usually a plastic insulating base covered with a metal shell, and a plurality of conductive terminals are combined in the insulating base. The USB connector is only supported by its several conductive terminals connected to the back-end substrate of the mobile hard disk. After repeated plugging and unplugging, the conductive terminals and the rear-end substrate are prone to poor contact, resulting in inability to read the content.

Therefore, the utility model aims at improving the problem of unstable connection between the connector and the substrate.
