Ac Adapter Having Foldable Prongs
(57) Abstract
A power adapter is disclosed with retractable prongs to engage an outlet and obtain power therefrom, when extended, and be partially or entirely within the housing of the power adapter when retracted. To ensure safe operation, a channel is provided within the power adapter to accommodate the prongs when retracted and to accommodate the prongs travel as they pivot between extended and retracted. The channel is width-limited and/or has a length to make it impossible or, at least, exceptionally difficult for a human finger to come into contact with the prongs while the prongs are extended and sufficiently engaged with an outlet to obtain power therefrom.
