The invention discloses an electric-shock-resistant socket, a matched plug and an electric-shock-resistant device comprising the two. The electric-shock-resistant socket comprises more than two inserting holes, a first electroconductive piece, a second electroconductive piece, a contactor and a normally-open reed pipe, the first electroconductive piece and the second electroconductive piece are embedded in the two inserting holes respectively, a normally-open contact of the contactor comprises a first synchronous switch and a second synchronous switch, a first end of the first synchronous switch is connected to the first electroconductive piece while a second end of the first synchronous switch is connected to a live line end of an external power source, a first end of the second synchronous switch is connected to the second electroconductive switch while a second end of the same is connected to a null line end of the external power source, and a coil of the contactor and the normally-open reed pipe are serially connected between the second end of the first synchronous switch and the second end of the second synchronous switch. Both the normally-open reed pipe and the contactor are utilized in the electric-shock-resistant socket, so that a user can be isolated from an electric-shock danger source of the socket, and safety in use of the socket is improved.
