Rotating plug of the present invention comprises: socket, three-terminal polarized plus plug.Described socket comprises: fore shell, bonnet, power supply lead wire cover, power supply lead wire, three pole jack slideways, horizontal electrode folder spring, described fore shell is provided with described three pole jack slideways and each jack slideway is made up of one group of jack communicated and the narrow slideway that meets.Crouch in described fore shell and be fixed with described horizontal electrode folder spring, horizontal electrode folder spring is corresponding with three pole jack slideways respectively, and the radian of horizontal electrode folder spring and three pole staged blade contact parts, consistent with three jack slideway place, pole circumference arc, the shape that horizontal electrode presss from both sides spring and three pole staged blade contact parts matches.Be equipped with in the side of described fore shell longitudinal direction described power supply lead wire cover and power supply lead wire, described bonnet be fixed on described fore shell.Have in described three pole jack slideways two jack slideways be distributed in radius identical circumferentially, jack slideway that another one width is less be distributed in radius be greater than the first two circumferentially, its radian is all consistent with the circumference arc at place.
Described three-terminal polarized plus plug comprises: three pole staged inserted sheets, three pole power supply lead wire covers, three pole power supply lead wires, described three pole staged inserted sheets, three pole power supply lead wire covers, three pole power supply lead wires are all fixed on three-terminal polarized plus plug, and three pole power supply lead wire covers, three pole power supply lead wires are horizontal fixing on three-terminal polarized plus plug.Described three pole staged inserted sheets adopt stairsteppings, laterally in certain radian, the radian of radian and three corresponding pole jack slideways and to press from both sides the radian of spring contact portion consistent with horizontal electrode, and the thickness inserting horizontal electrode folder spring side is greater than opposite side, have in three pole staged inserted sheets two be distributed in radius identical circumferentially, the radius that is distributed in that another one width is less is greater than the first two three pole staged inserted sheet circumferentially.
Described three-terminal polarized plus plug inserts socket, three pole staged inserted sheets and horizontal electrode press from both sides after spring contacts, and socket power goes between contrary with the direction of plug three pole power supply lead wire.
Beneficial effect of the present invention is, this plug achieves ultrathin, reduces taking of space.The incompatible other products of plug, only do single cooperation, the contact-making surface between socket electrode folder spring and plug electrode inserted sheet is large, ensure that larger live load.After plug insertion socket, be clamped in the horizontal electrode folder spring of partial insertion socket that plug staged inserted sheet is thick, the part that staged inserted sheet is thin enters in receptacle sockets slideway narrow slit slideway, due between can not rock between minimum, the plug of fit clearance, ensure that the long-term good contact between socket and plug.After plug insertion socket, the thick part of plug staged inserted sheet keep off by jack slideway narrow slit slideway, plug cannot vertically extract, and serves locking action between plug and socket.After plug insertion socket, plug-in power pack goes between and socket power goes between in rightabout, even if pull power supply lead wire to be that clockwise direction firmly pulls plug-in power pack lead-in wire also can not be separated with socket to the power that plug produces.Horizontal electrode folder spring be fixed on jack slideway narrow slit slideway below, only have when plug insertion socket and clockwise direction rotate after, staged inserted sheet could with horizontal electrode press from both sides spring contact, use safer.The thickness that plug staged inserted sheet inserts horizontal electrode folder spring side is greater than opposite side, its cross section like trapezoidal, and horizontal electrode folder spring and staged blade contact partial shape match, increase horizontal electrode presss from both sides effect that spring clamps and the resistance that staged inserted sheet is extracted.
