Abstract

A modular stackable USB hub system including a stackable USB. The stackable USB hub having an upstream power port for mounting to other upstream components in the stackable component system. The upstream power port includes an upstream power port connector, a voltage conductor and ground conductor for receiving voltage and ground from the upstream component to supply the high current requirements of the USB hub in high power applications. The stackable USB hub further includes a downstream power port for mounting to other downstream components in the modular stackable component system. The downstream power port includes a downstream power port connector, a voltage conductor and a ground conductor. The voltage and ground conductors are connected to the respective voltage and ground conductors of the USB upstream power port connector for passing voltage and ground to the downstream component connected to the downstream power port. The modular stackable USB hub system includes other components such as a base unit having a suitable power port for releasably mounting to the stackable USB hub.

Claims

1. A base unit releasably mountable to the housing of a stackable component, said base unit comprising:

a housing;

at least one outlet for distributing AC power to an electrical component connected thereto;

a downstream power port disposed on said housing for removably mounting said base unit to a downstream stackable component and for providing voltage and ground to the downstream stackable component; and

a bay disposed in said housing for receiving a surge suppressor module.

2. The invention defined in claim 1 wherein said downstream power port includes a downstream power port connector, a voltage conductor and a ground conductor for passing voltage and ground to the downstream component connected to the downstream power port.

3. The invention defined in claim 2 wherein said downstream power port connector includes a recess extending into said housing, said recess being shaped to receive an upstream power port disposed on said downstream component, wherein said upstream power port is similar to said upstream power port disposed on said stackable USB hub.

4. The invention defined in claim 2 wherein said downstream power port connector includes a boss protruding from the housing and a pair of flanges, each of said flanges extending from the opposite side of the boss, and a groove defined between each of said flanges and said housing.
