Patent ID: 7527508

Claim:
A sliding safety structure for power supply receptacles located on a path of a plug prong inserting to a receptacle electrode, comprising: a control dock which is located on a loading surface formed in a power supply receptacle and has a directing stem; and a safety gate which is slidably located on the directing stem and has a sliding path and is pushed by one end of at least one elastic element interposed between thereof and the control dock so that the control dock is pushed by another end of the elastic element such that the safety gate is moved to a latched position in regular conditions; the safety gate also has two force receiving portions blocking the path of the plug prong at the latched position and inserted and propped up by the plug prong to force the safety gate to escape from the latched position when the plug prong is inserted into the power supply receptacle to connect the receptacle electrode; the safety gate further has a stopper below the sliding path to harness the safety gate to remain at the latched position when the two force receiving portions receive uneven forces.
