Patent ID: 8475187

Claim:
An electrical charger comprising: a charger assembly including: a base unit configured for being electrically coupled to an electronic device wherein the base unit includes an electrical connector plug; and an adaptor unit configured for being electrically coupled to a power supply wherein the adaptor unit includes an electrical connector plug receiving receptacle configured for receiving the electrical connector plug; wherein, after the electrical connector plug is received within the electrical connector plug receiving receptacle and while the electrical connector plug is disposed within the electrical connector plug receiving receptacle, the electrical connector plug is disposable to an electrical coupling relationship with the adaptor unit 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 the electrical connector plug becomes disposed in the electrical contact relationship with the adaptor unit, power is supplied to the electronic device; and a locking assembly including at least one operative detent member, wherein each one of the at least one operative detent member is disposed outside of the periphery of the receptacle; wherein there is provided a locked state, wherein the base unit is disposed in the electrical coupling relationship with the adaptor unit and movement of the base unit relative to the adaptor unit, such that the base unit becomes disposed in an electrically uncoupled relationship with the adaptor unit, is resisted, and such that there is provided an unlocked state wherein the base unit is moveable relative to the adaptor unit; and wherein, in the locked state, each one of the at least one operative detent member is biased into an interference relationship with the charger assembly so as to resist the relative movement between the base unit and the adaptor unit which would effect the electrical uncoupling of the base unit from the adaptor unit; and wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit; and wherein the external surfaces of the base unit and the adaptor unit include co-operating external geometries that provide a visual indication whether the charger assembly is disposed in the locked state or the unlocked state.
