Modularized universal serial bus hub

A universal serial bus hub system comprising:

• a modularized power unit comprising:
• a power unit housing;
• a power terminal for transmitting power signals;
• and
• a power port installed in said power unit housing connectable to a power supply;
• a modularized basic unit mechanically and electrically connectable to the power unit, the modularized basic unit comprising:
• a basic unit housing;
• a computer port connectable to a computer for exchanging data signals with the computer;
• a basic unit power terminal connectable to the power terminal of the power unit for receiving the power signals;
• a basic unit signal terminal for communicating the power signals and the data signals;
• and
• at least one device port connectable to at least one peripheral device;
• a modularized extension unit mechanically and electrically connectable to the extension unit, the modularized extension unit comprising:
• an extension unit housing;
• a first signal terminal connectable to the basic unit signal terminal of the basic unit for receiving the power signal from the basic unit and for exchanging the data signals with the basic unit;
• a second signal terminal for transmitting the power signal and for exchanging the data signals;
• and
• at least one device port connectable to at least one peripheral device;
• wherein each of the mentioned units can be modularized and can be mechanically connected to each other;
• a first signal connection unit connectable between the power unit and the basic unit to transmit the power signal from the power unit to the basic unit;
• and
• a second signal connection unit connectable between the basic unit and the extension unit to transmit the power signal from the basic unit to the extension unit and to couple the data signals between the basic unit and the extension unit.
