Description

Technical Field

[0001] This utility model relates to the field of computer technology, specifically to a computer communication interface expansion structure. Background Technology

[0002] A computer's communication interface is a physical interface that connects communication devices for information transmission. Its function is to convert digital signals from the sender into signals suitable for the transmission medium and send them to the receiver, while converting signals returned from the receiver into digital signals suitable for the sender to process. Computer communication interfaces include USB interfaces, VGA interfaces, HDMI interfaces, etc. Expanding the communication interfaces can solve the problem of insufficient interfaces and improve data transmission speed.

[0003] The "Dustproof USB Expansion Interface for Computers" disclosed in application number "201610696971.3" includes an expansion interface body, a USB plug mechanism, a dustproof socket mechanism, a dustproof cover mechanism, a PCB circuit board, and a USB port. The expansion interface body has a USB socket mechanism on one side and a dustproof socket mechanism on the other side. The USB plug mechanism has a dustproof cover mechanism on one side. The expansion interface body has a PCB circuit board on its inner side, and a USB port is soldered to one side of the PCB circuit board. This dustproof USB expansion interface effectively protects the USB port from dust through the dustproof socket mechanism and protects the USB plug from dust through the dustproof cover mechanism. The USB plug mechanism is also adjustable in height to prevent the USB expansion interface from obstructing other computer interfaces.

[0004] However, the above method still has the following drawbacks: the dustproof connector mechanism can prevent the USB port from getting dusty, but the two baffles of the dustproof connector mechanism are supported by torsion springs, which can easily cause friction between them and the device connector. The resistance is large when unplugging the device connector, which can easily lead to wear on the surface of the device connector. After the baffle is damaged, it is not easy to disassemble and replace it. When the required device cable is short, it is difficult to connect the device effectively. Utility Model Content
