One connector is formed as a plug, and the other connector is formed as a socket. The connectors have are shaped having a profile that is a function of the respective connector power rating. A keyed portion of the power source connector plug will physically interfere with and not be receivable within a device connector socket when the device connector power rating exceeds the power source connector power rating. This connector system ensures target portable electronic devices coupled to the device connector can not draw power exceeding the rating of the power source connector.
CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Continuation of U.S. patent application Ser. No. 11/642,273 entitled �POWER CONVERTER HAVING POWER RATING FOR PORTABLE ELECTRONIC DEVICES� filed Dec. 19, 2006, which is a Continuation of U.S. patent application Ser. No. 10/790,877 entitled �Keyed Universal Power Tip and Power Source Connectors� filed Mar. 2, 2004, now issued as U.S. Pat. No. 6,976,885.
FIELD OF INVENTION The present invention is generally related to electrical connectors, and more particularly to electrical connectors suitable for use with portable electronic devices having varying power requirements, including laptop computers, PDA's, mobile phones, MP3 players, digital cameras, and portable DVD players.
SUMMARY OF THE INVENTION The present invention achieves technical advantages as an electrical connector, a set of connectors, and a connector' system whereby device connectors are backward compatible with power source connectors such that the device connectors can only be coupled to a power source connector rated at or above the power rating of the power source connector. For instance, a 35 Watt rated device connector can only be coupled with a power source connector rated at 35 Watts and above. Similarly, a 15 Watt device connector can only be coupled to power source connectors rated at 15 Watts and above. The portable electronic device to be powered from drawing power in excess of the power source connector and associated cabling.
DETAILED DESCRIPTION Referring now to FIG. 1, there is generally shown at Keyed connector system 10 comprising a set of device connectors generally shown at 12 and a set of power source connectors generally shown at 30. By way of example, but without limitation to this preferred embodiment, the device connectors are shown to have a connector interface configured as a receptacle, and the power source connectors are configured as plugs. Of course, one skilled in the art will appreciate that the device connector interfaces could comprise of plugs, and the power source connectors could comprise of receptacles if desired.
