ABSTRACT:
Peripheral devices are connected to the receptacle of a central processing unit (CPU) or to a hub using an “A” type universal serial bus (USB) connector plug and receptacle that ensures a positive connection regardless of the relative orientation of the two components. This is achieved mechanically, electronically, or through a combination of both. In one embodiment, the receptacle includes a bidirectional backplane that permits electrical contacts within the receptacle to slide or move in a direction that is perpendicular to the linear direction of the connector and its connecting cables. Another option is to use an orientation sensor such as a pressure transducer which serves to detect the orientation of the plug with respect to the receptacle. Another feature is the use of a multi-layer printed circuit board to cross or reverse the pins in the plug, such as D+ to D− and Power to Ground.
