The technical solution of the utility model: it is box-like that jack housing is the rectangle of an opening, the bottom is provided with the contact electrode, short pairing two madial walls in limit of the opening part length of side are provided with pivot slot and auxiliary fulcrum, there is fixedly edge in two outsides, movable block tongue and fixing block tongue are housed in long limit one sidewall of the opening part length of side, and movable block tongue keeps inside pulling force under the effect of spring.Middle part in the jack shell is provided with resilient contact formula electrode, opening part has protecting cover, the arrangement of resilient contact formula electrode is consistent with socket contact formula electrode, plug master apparent direction is hexagon, side opposite the angle is parallel to each other up and down, front and the back side is provided with fulcrum and auxiliary pivot slot, the face of plug master apparent direction below is provided with location notch and draw-in groove, and the other end of plug is provided with power supply lead wire sheath and power supply lead wire.During plug insertion socket, the location notch of plug needs the movable block tongue of subtend socket and fixing block tongue, the auxiliary fulcrum of socket can be used to regulate the angle that plug inserts in the process of inserting, make it keep horizontal direction to insert, keep the interelectrode distance of plug and socket, when insertion puts in place, the plug fulcrum all enters in the pivot slot of socket, and can to make fulcrum be that small size rotation is done in the axle center with pivot slot bottom, press plug downwards, when finishing half left and right sides of stroke, plug resilient contact formula electrode contacts with socket contact formula electrode, when finishing whole stroke, the reed of plug resilient contact formula electrode occurs crooked, the pressure that is produced makes plug resilient contact formula electrode and socket contact formula electrode keep closely contacting, the both sides of plug draw-in groove are gone in the fixed card tonguing of socket simultaneously, the crooked male member of movable block tongue is stuck in the middle part of plug draw-in groove, the auxiliary fulcrum of socket inserts in the auxiliary pivot slot of plug, because the strength of the movable block tongue spring strength after greater than plug resilient contact formula electrode spring bending tablet, make plugs and sockets remain on contact condition, fixedly block tongue is stuck in the draw-in groove, plug can't horizontal direction be extracted.If pull the plug out of the socket, only need with thumb be placed on the socket top edge, forefinger is placed on plug bottom and upwards removes and can extract.The number of electrodes of the utility model socket plug can be designed to single-phase 2 lines, single-phase 3 lines, three-phase 3 lines, three-phase 4 lines, but contact electrode, resilient contact formula electrode isosceles triangle, single or double arrangement, and socket, plug volume also can design as required.
The convenient socket plug of the utility model contact comprises: socket, plug.Described socket comprises: jack housing, the contact electrode, pivot slot, auxiliary fulcrum, fixing edge, movable block tongue, fixing block tongue, spring, described contact electrode is fixed on the bottom of described jack housing, described pivot slot is located on short corresponding two madial walls in limit of the described jack housing opening part length of side, described auxiliary fulcrum is located near in the described pivot slot of jack housing mural margin, described fixedly edge is located at short corresponding two outsides, limit of the jack housing opening part length of side, described movable block tongue and fixedly block tongue be located at bigger shell wall one side of described jack housing thickness, described movable block tongue and fixedly on the block tongue described spring is housed.
Described plug comprises: resilient contact formula electrode, fulcrum, auxiliary pivot slot, location notch, draw-in groove, protecting cover, power supply lead wire sheath, power supply lead wire, described resilient contact formula electrode is fixed on the middle part in the jack shell, described fulcrum is located at the front and the back side of plug master apparent direction, described auxiliary pivot slot is located at the below of described fulcrum, described location notch and draw-in groove are located on the face of plug master apparent direction below, described protecting cover is installed in the opening part of plug, and described power supply lead wire sheath and power supply lead wire are fixed on the other end of plug.
The angle of described pivot slot bottom interior angle is greater than the angle of the described fulcrum that cooperates with this part, and the height of described pivot slot is greater than described fulcrum, auxiliary fulcrum height sum.
Described movable block tongue exposed portions serve is positioned at the middle part of jack housing wall, fixedly the block tongue exposed portions serve is positioned at the both sides of movable block tongue, movable block tongue, the fixedly block tongue inside bending of part of exposing, and the part of movable block tongue bending also has aduncate convex.
One end of described spring hangs on the fixedly block tongue flanging that is hidden in the shell wall, the spring other end hangs on the movable block tongue flanging that is hidden in the shell wall.
The main apparent direction of described plug is hexagon (not comprising power supply lead wire sheath and power supply lead wire), two groups of side opposite the angles are parallel to each other up and down.
Contact on described contact electrode, the resilient contact formula electrode is an alloy, and the reed of resilient contact formula electrode is the elasticity phosphorus bronze sheet, but contact electrode, resilient contact formula electrode isosceles triangle, single or double arrangement.
Described location notch and movable block tongue exposed portions serve and fixedly the block tongue exposed portions serve cooperate, the two ends of described draw-in groove cooperate with fixing block tongue exposed portions serve, the middle part of draw-in groove cooperates with movable block tongue exposed portions serve.
The beneficial effects of the utility model are, the contact electrode of socket plug adopts alloy with the contact on the resilient contact formula electrode, adds the effect of resilient contact formula electrode reed, can ensure interelectrode good contact of contact electrode and resilient contact formula, is difficult for causing the heating of electrode contact portion or producing arc phenomenon, big, the long service life of live load because of loose contact.During the electrode separation of socket plug, because, when being beneficial to on-load disconnecting extinguish arcs fast by the separated speed in the effect contact of movable block tongue spring.Plug can not have to insert socket under the situation of resistance, press plug downwards and can contact, realize one-handed performance with the socket electrode, to the plug plug frequent, to move the small-sized high-power electrical equipment that uses very convenient.Produce the strength that inside pulling force and strength are produced after greater than the bending of resilient contact formula electrode reed at movable block tongue under the effect of spring, can not cause loosening between socket and plug behind the plug insertion socket, also can be because of not being subjected to the horizontal direction pulling force and downward pulling force separates.
