Abstract: Disclosed are a power connector module and a power connector thereof, and the power connector includes an insulating body, a conductive structure and a waterproof cushion. The insulating body has a groove and a bottom wall formed inside the groove, and the bottom wall has one or more penetrating holes; the conductive structure includes one or more conductive terminals, and the conductive terminal is plugged and fixed into the penetrating hole and protruded from the bottom wall; and the waterproof cushion has one or more through holes for passing and installing the conductive terminal. If the waterproof cushion is pressed and deformed, the periphery of the conductive terminal will be in a sealed status to achieve the effect of providing a waterproof function to the power connector module and the power connector and improve the safety of use.
