The invention relates to a protection socket, comprising a socket body, wherein insertion slots are arranged on the socket body, slot bottoms of the insertion slots are provided with jacks matched with plug pins and protection doors adaptive to the jacks, and the protective socket also comprises a panel covering the cross section of the insertion slots, the panel moves up and down along the peripheral wall of the insertion slots; A limiting convex post is arranged at the bottom of the panel, and a stop block is arrange on the protection door. When the protection door covers the jack hole, thebottom end of the limiting convex post abuts on the upper surface of the stop block; When the protective door exposes the jack hole, the stopper avoids the limiting protrusion. Children are preventedfrom stretching a hand into the socket insertion holes to cause danger, and the accumulation of dust, water drops and other materials that can reduce the distance of electrical insulation is prevented, so as to avoid electric shock when touching.
