A multi-functional transfer connector comprising:

• a base insulative housing defining a first receiving cavity and a second receiving cavity between two opposite faces thereof in a first direction in a peripherally closed manner, and spaced from each other in a second direction perpendicular to the first direction;
• a first connector unit disposed in the first receiving cavity and defining at least a first mating port;
• a second connector unit disposed in the second receiving cavity and defining at least a second mating port;
• and
• a cable attached to the common housing and enclosing a plurality of wire units, each of said wire units having first and second connecting ends respectively connecting to the first mating port of the first connector unit and the second mating port of the second connector unit so as to have said first connector unit and said second connector unit operated independent from each other;
• wherein at least the first mating port of the first connector unit is received in the first receiving cavity without exposure to an exterior in an inoperable manner while available to be rotated out of the first receiving space in the first direction to be exposed to the exterior in an operable manner for mating a base plug;
• the base plug is located around an outer side of the insulative base housing.
