Abstract A star-shaped array of limbs projects radially outwardly from a central circular cylindrical hub in clamping engagement with an electrical plug. With the plug prongs inserted in the respective slots of an electrical wall outlet, the outer extremities of the radial limbs engage the surface of the underlying wall in the vicinity of the cover plate of the electrical outlet. The limbs are of sufficient length so that even though the electrical conductor connected to the plug is pulled laterally, the plug prongs are compelled to withdraw substantially axially from the outlet. The outer extremity of one or more of the limbs serves as a fulcrum about which the outlet guard tilts as plug withdrawal occurs, the radial distance from the plug axis to the fulcrum being such that only a minimal amount of lateral component is exerted on the plug prongs and outlet as the plug is withdrawn. Damage to plug and outlet is thereby eliminated despite misuse and negligent handling of the plug and conductor connected to the plug.
Electrical outlet guard comprising: a. a central hub shaped to receive an electrical plug and orient the prongs of the plug into alignment with the slots of an electrical wall outlet when said guard is located against the wall in register with the outlet, said central hub being of hollow right circular cylindrical configuration, and means on said hub for releasably clamping said guard to the electrical plug; b. at least three circumferentially spaced limbs each mounted at one end on said hub said limbs being arrayed in radial fashion relative to the axis of said hub, at least one of said limbs being provided with a radial slot extending through the adjacent portion of said hub, said clamping means including means for urging the slot walls into closed position with the plug disposed within said hub for clamping engagement thereby as the slot is closed; and, c. a leg mounted on the other end of each of said limbs, the ends of said legs normally contacting the wall surface externally of a cover plate of the wall outlet, said legs being spaced at a distance from said hub such that the prongs of the plug remain substantially in alignment with the wall outlet slots as said guard is tilted away from the wall in any direction with at least one of said legs serving as a fulcrum as the plug is withdrawn and the tips of the prongs are moved from a first engaged position in the outlet to a second position in which the prong tips disengage the outlet.
