First Claim
Patent Images
1. A connector adapted to accept a mating connector on the end of a bus comprising:
- a. a plurality of contacts including at least two power contacts, each adapted to make contact with a corresponding contact in the mating connector; and
b. an additional contact mated to one of said plurality of contacts, such that, when no mating connector is plugged into said connector, said mated contact is not shorted to said one of said plurality of contacts and when a mating connector is plugged into said connector, said additional mated contact is shorted to the one of said plurality of contacts to which it is mated.

Abstract
A power supply supplies power from a bus at a hub to a peripheral over a bus which plugs into a connector at the hub, the connector having a plurality of contacts, including at least two power contacts the power supply. When the bus is plugged into the connector, a mated contact is provided in the connector at the hub. When a mating connector on the bus is plugged in, one of the plurality of contacts is shorted to the mated contact. The sensed shorting at the mated contact is used to control the ramping of current on the power lines of connector.

5. A bus hub comprising:
-
a. a bus which has lines for power and data; and b. a connector adapted to accept a mating connector, said connector including a plurality of contacts, one coupled to each line of said bus and each adapted to make contact with a corresponding contact in the mating connector, and an additional contact mated to one of said plurality of contacts, such that, when no mating connector is plugged into said connector, said additional contact is not shorted to said one of said plurality of contacts and, when a mating connector is plugged into said connector, said additional mated contact is shorted to the one of said plurality of contacts to which is mated. - View Dependent Claims (6, 7, 8, 9)

10. A computer system comprising:
-
a. a hub including; i. a bus which has lines for power; and ii. a hub connector including a plurality of contacts, each coupled to a respective line of said bus and each adapted to make contact with a corresponding contact in the mating connector, and an additional contact mated to one of said plurality of contacts such that, when no mating connector is plugged into said connector, said additional contact is not shorted to said one of said plurality of contacts and, when a mating connector is plugged into said connector, said additional mated contact is shorted to the one of said plurality of contacts to which is mated, b. a bus having a mating connector on one end thereof coupled to said hub connector said mating connector causing said additional mated contact to be shorted to the one of said plurality of contacts to which it is mated; and c. a peripheral at the other end of said bus to which power is supplied via said bus. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of reducing the overloading of a power supply which supplies power from a bus at a hub to a peripheral over a bus which plugs into a connector at the hub, said connector having a plurality of contacts, including at least two power contacts, when a mating connector on the bus is plugged into said connector, comprising:
-
a. shorting one of said plurality of contacts to a mated contact; b. sensing the shorting at said mated contact; and c. controlling the ramping of current on the power contacts of said connector in response to said sensing. - View Dependent Claims (19)
