The present invention relates to a ground terminal of a USB plug connector, a grounding structure of a USB plug connector, a USB plug connector, a USB plug cable device, and a USB connector assembly.

In recent years, a C-type USB connector having a reduced size and a free connection direction compared to a conventional A-type or B-type USB connector has been released. Such a C type USB connector is formed in a vertically and horizontally symmetrical shape different from a conventional A type or B type USB connector, so that the direction of connection between the USB plug connector and the USB receptacle connector is not limited.

On the other hand, a cable connected to the C type USB connector generally includes one power line, two signal lines and one ground line. However, as described above, since the C type USB connector has no restriction on the coupling direction, the ground terminal is composed of two provided on both sides of the USB connector so as to be symmetrical to the left and right and up and down. Therefore, conventionally, it is inconvenient to connect two ground terminals to one ground line by using a PCB.
