Existing Powered USB connectors provide higher voltages and current than specified in the USB 1.1 and 2.0 Standard. This particular connector height precludes use in small applications such as LCD displays, ultra thin Lap top computers, payment terminals, consumer service devices, and other electronic devices. This publication describes a connector with unique keying features to provide USB signaling with integrated multiple voltages in a low profile form factor. This is an enhancement to the existing IBM patent US 6,334,793B1 attached below, which outlines the original IBM patent for a powered USB connector in a 'dual height' form factor.

(RSS) Low Profile Powered USB Connector with Multiple Key Arrangements

     The present version of the Powered USB connector locates the secondary voltage contacts above the USB signal portion of the connector. This invention relocates the voltage and signal conductors to a side-side arrangement and simplifies the voltage contacts with a barrel type contact. Reference Figures 1 and 2 attached below. The USB signal section is compatible with the USB 1.1 and USB 2.0 standard. The secondary voltage conductors can be a standard barrel type power jack to simplify the mating plug.

     In addition, locking latches are provided on the connector sides rather than on top as with the existing Powered USB Connector. The latches are an improvement over the standard USB connector by providing secure connection with substantially higher pull force than without latches. The side latches also reduces the total connector operating height to the minimum amount to be compatible w/ standard USB.

     An alternate feature which can be implemented uses a unique keying method for allowing multiple secondary voltages. Figure 2 shows various shapes for the secondary voltage contacts. The key shape is created such that only the proper shape plug will insert into the corresponding receptacle shape.
