Abstract
A sliding safety structure for power supply receptacles located on a path of a plug prong inserting to a receptacle electrode includes a control dock which has a directing stem, a safety gate slidably located on the directing stem and an elastic element which has two ends pushing respectively the control dock and the safety gate. The safety gate has two force receiving portions which are pushed by the elastic element in regular conditions to block the path of the plug prong inserting to the receptacle electrode and maintain at a latched position. When the plug prong is inserted into the receptacle, the two force receiving portions are depressed by the plug prong to move the safety gate to slide away from the latched position so that insertion of the plug prong to the electrode of the power supply receptacle is allowed. The safety gate also has a stopper below the sliding path thereof to harness the safety gate at the latched position when the two force receiving portions receive uneven forces. Thus an enhanced safety effect can be accomplished to improve the disadvantage occurred to the conventional safety structure which is openable when subject to a force at one side.
