Embodiment one：

In Fig. 1, a kind of plugs and sockets of protection against electric shock Anti-extrusion described in the present embodiment, including housing 100, socket core 200, Plug 300, housing 100 are fixed or portable, and fixed sandwich type element 100 includes exposed type, concealed, half concealed, panelling Formula, architrave formula, desk-top, floor be concealed or the mounting means of the subsidiary formula of utensil, i.e. the housing 100 of the socket can be it is any Know the fixed installation mode of type, its profile and installation fixed form are not restricted by.Housing 100 is provided with least one socket Core 200, connected between socket core 200 and housing 100 and/or between socket core 200 by cable, cable can be the gold of multiply winding Belong to wire or the single metallic conductor with forms such as silk, bar, rod, pieces, for the more excellent electric conductivity of acquisition and surely Solid connection, preferably bonding jumper, metal bar connect socket core 200 and housing 100.

Such as Fig. 2, plug 300 supports the use with socket core 200；The socket core 200 includes fixed part 210, rotor portions 220, fixed part 210 is fixed on housing 100, and rotor portions 220 are nested in fixed part 210, and it can turn in fixed part 210 Dynamic, the front end of rotor portions 220 and housing 100 use face flush, and rotor portions 220 are provided with sleeve 221, sleeve 221 for positioning, Connection, locking-type plug；The housing 100, socket core 200 etc. are made by insulation, fire resisting, fire proofing, to ensure socket Security.

Such as Fig. 3,4,5, fixed part 210 is provided with least one pellet 230, pellet 230 include pedestal 231, bullet core 232, Spring 233, the pedestal 231 of pellet 230 are arranged on the inwall of fixed part 210, and the periphery of rotor portions 220 is provided with matches somebody with somebody with pedestal 231 The chute 222 of set, pellet 230 can slide in chute 222, and the corresponding position of sleeve 221 of rotor portions 220 is provided with lockhole, pellet 230 Bullet core 232 spring into lockhole, by the locking of rotor portions 220；

Fixed part 210 is provided with conductor 211, and conductor 211 is led with the live wire and/or zero line and/or ground wire of external power source respectively It is logical；

The plug 300 includes handle 310, latch 320, and latch 320 is fixed on handle 310, latch 320 and socket core Sleeve 221 in 200 rotor portions 220 matches.

In use, plug 300 is inserted to the sleeve 221 of rotor portions 220, while the latch 320 of plug 300 can be by pellet 230 bullet core 232 ejects, so that rotor portions 220 can rotate in fixed part 210；Plug 300 is inserted into the bottom of sleeve 221 Afterwards, the front end of latch 320 is stretched out the bottom of sleeve 221 and exposed, and now, rotor portions 220 is rotated to an angle, latch 320 is gone to It is fixedly clamped at conductor 211 and therewith, circuit is connected.

Further, the latch 320 and sleeve 221 include 2P or 2P+E type so that this socket can adapt to band Ground wire or the plug 300 without ground wire.To make conductor 211 and plug 300（Latch 320）Connect even closer, the conductor 211 are provided with least one tight spring 212, conductor 211 are extruded to the side of latch 320, it is preferable that tight spring 212 can be arranged on latch 320 with the junction of conductor 211, make stress optimal.

Further, return torsion spring is provided between the fixed part 210 and rotor portions 220（Not shown in figure）, and it is turned round Power is less than frictional force when latch 320 is connected with conductor 211, so as to not make latch when latch 320 is connected with conductor 211 320 are separated with conductor 211.In use, first plug 300 is rotated from socket core 200, extracted, now, rotor portions 220 with There is no other stress to support situation between fixed part 210, rotor portions 220 are repositioned to by rotor portions 220 in the presence of return torsion spring Initial position, i.e. pellet 230 will not arbitrarily rotate the position of the locking of rotor portions 220, rotor portions 220.In addition, rotor portions 220 when being in initial position, and because of sleeve, 221 are isolated with conductor 211, even if having foreign matter or metallic object insertion socket, also not It can get an electric shock.

Further, the latch 320 and sleeve 221 are the flat key type for meeting national standard, to improve the general of equipment Property, and latch 320 and sleeve 221, when latch 320 inserts sleeve 221 and is connected with conductor 211, are laterally set in laterally setting The latch 320 put can provide larger side and support force, make the connection of latch 320 and conductor 211 more stable.

Embodiment two：

As shown in Figure 6,7, on the basis of above-described embodiment, latch 320 described in the present embodiment is provided with groove 321, groove 321 match with the size of conductor 211.In above-described embodiment, latch 320 with conductor 211 is tieed up by extruding, frictionally Shield connection, as external force exceeds the frictional force, latch 320（Plug 300）It can deviate from from socket core 200.The present embodiment is in latch 320 are provided with groove 321, and when plug 300 inserts sleeve 221 and rotates and be connected with conductor 211, conductor 211 will be snapped into slotting In groove 321 on pin 320, now, latch 320 is connected with conductor 211 by rigid structure, and its stability is better than above-mentioned Embodiment.Certainly, the connection of above-mentioned rigid structure nor preferred plan, quick separating is unable to as there are both emergencies, therefore Groove 321 can be also designed to the structure with certain slope, make it on the basis of effectively connection is safeguarded, additionally it is possible to be forced Abjection.

Embodiment three：

As shown in Figure 8,9, on the basis of above-described embodiment, latch 320 described in the present embodiment and sleeve 221 are longitudinally disposed. Cotter pilotage on conventional male prongs 300 is longitudinally disposed, and now above-described embodiment can not be then used, it is necessary to be equipped with special plug 300.To improve versatility of the present utility model, the present embodiment is longitudinally disposed by latch 320 and sleeve 221, i.e., sleeve 221 is complete Meet in national standard to the design requirement of latch 320 so that the new connection that can be directly used for conventional male prongs 300 of this implementation, improve Its versatility.

In addition, when sleeve 221 and supporting conductor 211 are required using plug 300 with groove 321, the present embodiment can be Corresponding groove 321 is dug in the front end of latch 320 of conventional male prongs 300, allows it to support the use with socket core 200.

Example IV：

The latch 320 is provided with detent projection, and it matches with the pellet 230 on fixed part 210, and pellet 230 wraps Include at least one bullet core 232, after the detent projection on latch 320 matches with the bullet core 232 of pellet 230, the rotor driven of latch 320 Portion 220 is rotated in fixed part 210, that is to say, that simple Key structure is set on latch 320, makes latch 320 with spy Fixed detent projection, and the bullet core 232 of pellet 230 matches therewith, realizes that the latch 320 for there was only specific thread form could insert simultaneously Rotor portions 220 are rotated, further increase security of the present utility model.

Embodiment five：

The sleeve 221 is flexibly connected with rotor portions 220, i.e., sleeve 221 has cylindrical structural, can be in rotor portions Rotation on 220, sleeve 221 is set to possess a variety of location status such as transverse direction, longitudinal direction, inclination, to adapt to different types of plug 300.

It should be noted last that above embodiment is only illustrating the technical scheme of the invention rather than limit System, although the invention is described in detail with reference to example, it will be understood by those within the art that, can be right The technical scheme of the invention is modified or equivalent substitution, without departing from the spirit and model of the invention technical scheme Enclose, it all should cover among the right of the invention.
