US Patent 7914307 Socket with movable lids for shielding plug holes

A socket featuring movable lids for shielding plug holes is characterized by accommodating a set of movable lids: a first lid, a second lid and an elastic member in a cavity of its panel, where the first lid and the second lid are used to barricade the first notch and the second notch respectively by the bottoms of their tapered surfaces. A user, on occasion, is inserting a stick-like object into a single plug hole incidentally or intentionally, the first lid and the second lid will hold up each other to barricade the corresponding notch to avoid the stick-like object to touch the specific conducting clip, keeping the user from the hazard of an electrical shock.
