Safety socket and plug arrangement

A safety socket and plug arrangement comprising a socket unit for the connection of an electric plug, and a plug unit for connection to an electric socket, said socket unit comprising a plurality of slots in a front side thereof adapted for receiving the metal contact blades of an electric plug, and a plurality of electric terminals disposed in said slots, wherein:

• said socket unit comprises a baffle holder having a horizontal sliding rod and two recessed portions equally spaced from said horizontal sliding rod at two opposite sides, a safety baffle plate turned about and moved along said horizontal sliding rod, and two spring elements bilaterally connected between said baffle holder and said safety baffle plate to impart a forward pressure to said safety baffle plate, said safety baffle plate comprising a center axle hole which receives said horizontal sliding rod, two first top slopes disposed at two opposite sides, two second top slopes disposed at two opposite sides between said center axle hole and said first top slopes at a lower elevation than said first top slopes, each of said first top slopes having a top end terminating in a top flange, said safety baffle plate being forced forwards by said spring elements to block up said electric terminals from the slots of said socket unit, or moved backwards to compress said spring elements upon the insertion of the metal contact blades of an electric plug into the slots of said socket unit, for permitting the metal contact blades of the inserted electric plug to make contact with the electric terminals of said socket unit, said safety baffle plate being tilted to force the top flange of one of said first top slopes into engagement with one recessed portion of said baffle holder and prohibited from backward movement when a rod member is inserted through one slot of said socket unit and pressed on one of said top slopes.
