The liquid cooling tube 3 is used for conveying a liquid cooling medium, which in one embodiment is fed from the liquid cooling tube 3 into the liquid cooling connector plug 100 and then out through the first channel 23 of the cable, thus carrying heat. The plugging portion 41 of the connection terminal 4 is used for plugging the electrical contact member of the socket 200, and the plugging portion 41 may be in a jack shape or a pin shape, so long as the plugging portion can be adapted to plug with the electrical contact member of the socket 200.
