Abstract
The invention provides an electric shock prevention socket, and the socket comprises a substrate, wherein the front part of the substrate is provided with jacks. The insertion directions of the jacks are orthogonal to a chute in the substrate. The interior of the chute is provided with a sliding block. Two ends of the sliding block are symmetrically provided with metal spring pieces, wherein the sides, facing the jacks, of the metal springs form slops. The sliding block is deflected towards the right side to be inserted in the right jack in a non-use state under the action of a limiting mechanism. At this moment, the slope surface of the right side of the sliding block faces the right jack, and the slope of the left side is located between the two jacks. When a plug is completely inserted, the slope, facing the right jack, at the right side of the sliding block is jacked by a right pin of the plug, thereby driving the sliding block to slide towards the left side to an extreme position. At this moment, the metal spring pieces at two sides of the sliding blocks just support the inner sides of the two pins, and the metal spring piece at the right side of the sliding block is connected with a zero line. The metal spring piece at the left side is connected with a live line. The socket can avoid electric shock caused by the digging contact of the jacks, and is easy for plugging.
