Patent ID: 8057265

Claim:
An electrical charger comprising: a base unit configured for being coupled to an electronic device; and an adaptor unit configured for being coupled to a power supply; wherein the base unit includes an electrical connector plug that includes a plurality of electrical connector plug contacts; and wherein the adaptor unit includes a plurality of adaptor unit contacts and an electrical connector plug receiving receptacle configured for receiving the electrical connector plug; and wherein, after the electrical connector plug is removably received within the electrical connector plug receiving receptacle and while the electrical connector plug is disposed within the electrical connector plug receiving receptacle, upon rotation of the base unit relative to the adaptor unit, each one of the electrical connector plug contacts becomes disposed in a mechanical coupling state with the adaptor unit and blocked from axial separation, and also becomes disposed in an electrical coupling state with a respective one of the adaptor unit contacts such that, when the adaptor unit becomes disposed in electrical communication with a power supply and the base unit becomes disposed in an electrical coupling relationship with an electronic device and each one of the electrical connector plug contacts becomes disposed in electrical contact engagement with a respective one of the adaptor unit contacts, power is supplied to the electronic device.
