Description

Technical Field

[0002] USB, which is the abbreviation of Universal Serial Bus in English and "Tongchuanxian" in Chinese, is an external bus standard used to regulate the connection and communication between computers and external devices. It is an interface technology used in the PC field. The USB interface supports the plug-and-play and hot-swap functions of devices.

[0003] In the existing USB interface structure, in order to reduce the interference of external electrical signals, a detachable shielding cover is set on the back of the shell interface, that is, the back of the terminal assembly, and is connected to the shell interface by a snap-on fixing method. Such a design facilitates the terminal assembly to enter the shell interface. When multiple shielding covers are stacked together for transportation, the multiple shielding covers will be entangled with each other. In the actual assembly process, it takes time to separate them. During the separation process, the shielding cover is easily deformed by force, resulting in an increase in the scrap rate. Since the shielding cover is small in size and not easy to take, the assembly efficiency is reduced and the production cost is increased. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention
