The technical scheme is as follows: the utility model discloses an isolation power socket, including power supply circuit, insert this power supply circuit's socket and/or USB interface, its characterized in that, socket and/or USB interface and power supply circuit connecting portion still establish ties at least one normally open contact switch, the plug inserts the socket, the electrically conductive part extrusion of plug the normally open contact switch, normally open contact switch closure switches on power supply circuit and socket; and the USB equipment is inserted into the USB interface, the conductive part of the USB equipment extrudes the normally open contact switch, and the normally open contact switch is closed to conduct the power circuit and the USB interface.

The utility model discloses further preferred technical scheme does, the socket is two-hole socket or three-hole socket, all is provided with a normally open contact switch in the first jack of socket and the second jack, and two normally open contact switches are connected with power supply circuit's live wire and zero line respectively, and the plug inserts the socket, the conductive part of plug drive the copper sheet extrusion in the jack normally open contact switch, normally open contact switch closure switch on power supply circuit and socket.

Preferably, the normally open contact switch in the first jack is connected with one end of a first conducting strip, the normally open contact switch in the second jack is connected with one end of a second conducting strip, the first conducting strip and the second conducting strip are arranged in a crossed manner, the other end of the first conducting strip is connected with a copper sheet in the second jack, and the other end of the second conducting strip is connected with the copper sheet in the first jack; the first jack and the second jack are respectively provided with an insulating column, and the insulating columns are movably arranged in the jacks; the plug is inserted into the socket, the conductive part of the plug extrudes the insulating column, the insulating column extrudes the normally open contact switch, the normally open contact switch on one side of the first jack is communicated with the conductive part of the plug inserted into the second jack through the first conductive sheet, and the normally open contact switch on one side of the second jack is communicated with the conductive part of the plug inserted into the first jack through the second conductive sheet.

Has the advantages that: (1) the utility model discloses an isolation power socket sets up normally open contact switch at socket and/or USB interface and power supply circuit junction, when the socket uses, plug or USB equipment extrusion normally open contact switch make normally open contact switch closed, intercommunication socket and power supply circuit, after extracting plug or USB equipment, normally open contact switch disconnection socket and power supply circuit's connecting circuit, the exposed socket copper sheet of this moment and power supply circuit disconnection, the socket is uncharged, reduce the occurence of failure probably, eliminate the potential safety hazard;

(2) the utility model discloses in all be provided with a normally open contact switch in the first jack and the second jack of socket, normally open contact switch passes through the conducting strip and is connected with power supply circuit, and the conducting strip cross arrangement, when pressing down the copper sheet in one of them jack alone, the normally open contact switch of this side communicates power supply circuit and communicates the steel sheet in another jack through the conducting strip, and the copper sheet of this side is isolated with power supply circuit because the setting of insulating post, and is uncharged, can prevent the incident that the user from bumping the jack by mistake and leading to; when the socket is used normally, the normally open contact switches in the two jacks are closed simultaneously, and the normal use of the socket cannot be influenced.
