Background technology:

One of alternating current and galvanic notable feature are the branches that the former does not have positive and negative electrode, the substitute is fire, ground wire, but the two from the high and low of current potential and the opinion then similar, promptly positive pole or live wire are that high potential, negative pole or ground wire are electronegative potentials; Also similar from the loop analysis of forming circuit, promptly positive pole or live wire are that outlet, negative pole or ground wire are inlet wire or loop line for power supply, and be then just the opposite with respect to electrical appliance.Therefore, many general character and extremely important to safety utilization of electric power and operate as normal are arranged also between the two class power supplys,, high and low current potential difference is arranged, otherwise equally easily be damaged though do not have the positive and negative electrode requirement as many capacitors.In actual applications, DC power supply is because of must distinguish and fix the positive and negative electrode wiring of they and electrical appliance in advance, could drive electrical appliance and self normal and trouble free service, so just the positive and negative electrode wiring is fixed during in advance as manufacturing or installation, AC power also has similar safety utilization of electric power requirement and regulation.Yet to using extremely extensively and the AC power of enormous amount and in fact be the socket and plug that the AC and DC power supply all can be general, present product is difficult to all generally ensure that it buries many major hidden dangers with permanent correct the fixedlying connected of the high and low current potential of electrical appliance to safety utilization of electric power.Such lesson is a lot, sometimes or even very serious as fatal, cause great permanent disability etc., as because of plug to the freedom of socket and jack position thereof repeatedly conversion cause shell such as many household electrical appliances such as TV or sole plate metal is charged and use and damage and the electric shock and the injures and deaths of keeping in repair, because of power network fluctuation, thunderbolt, connector and patch loosening, break-make causes surge huge energy impact failure electrical equipment repeatedly repeatedly, and the contaminated environment and disturb other responsive electrical equipment such as computers of generating electromagnetic waves, equipment such as TV and wireless telecommunications, loose contact also can cause contact resistance to heighten and produce high heat and spark causes that serious accidents such as fire and consequence are not rarely seen, excess load or short circuit need artificial replacing or maintenance just can restore electricity after burning fuse, and often, all should be paid much attention to and be properly settled because of not having suitable even not having fuse to use the dangerous and inconvenient problem of electricity consumptions such as wire replacement.

Summary of the invention:

The purpose of this utility model provides the high electronegative potential Antisurge current plug and socket of a kind of differentiation, and above-mentioned fixing and surge current makes Electrical Safety potential problems such as electricity consumption is dangerous because of plug and the high electronegative potential wiring of socket to solve.

The technical scheme that its technical problem that solves the utility model adopts is: in the insulation crust of plug, one of thermistor and wide, narrow inserted sheet or wide, narrow inserting column are electrically connected in series, routinely wide, narrow inserted sheet or wide, narrow inserting column are fixed in the insulation crust of plug different permanent ferromagnetic substance such as the rare earth magnetic steel of fixed magnetic pole on the surface that plug and socket contacts with each other; In the insulation crust of socket, one of thermistor and wide, narrow socket or wide, narrow jack are electrically connected in series, routinely with wide, narrow socket or wide, fix in the insulation crust of socket different permanent ferromagnetic substance such as the rare earth magnetic steel of fixed magnetic pole on the surface that socket and plug contact with each other narrow jack week; Design will not have the inserted sheet of plug of position correspondence or the jack of inserting column and socket all manufactures to correspondence a wide narrow structure respectively, and the high and low equipotential line of power supply fixedly is connected electrically in respectively on the leg of corresponding with it socket or plug; Increase bed knife with opposite pole and mutual adsorption magnetic force thereof and prevent to patch loosening and loose contact; Weaken or eliminate surge current and harm thereof and make fuse and use with thermistor, tool automatic safe repeatedly restores electricity function and does not have trouble and the unsafe factor of changing fuse.

The beneficial effects of the utility model are: design all manufactures to correspondence a wide narrow structure respectively with the inserted sheet of the plug of present widely used no position correspondence or the jack of inserting column and socket, when the jack of the inserted sheet of plug or inserting column and socket by correspondence when manufacturing a wide narrow structure, have only patching of same correspondence may inject, so just only need high and low equipotential line with power supply fixedly be connected electrically in respectively can to finish and ensure correctly on the leg of corresponding with it socket or plug to patch; The different permanent ferromagnetic substance of fixed magnetic pole such as rare earth magnetic steel etc. on the surface that plug and socket contacts with each other, make plug and socket add strong fix and ensure that with fastening ability electrode contacts well by means of the powerful magnetic force of attracting each other, this is than present draw-in groove, nearly all fixing means such as screw socket is more convenient, when especially dismantling, and this is very important, because present a lot of electrical equipment is the household electrical appliances such as the microwave oven of a multitude of names particularly, electric furnace, electric cooker, electric frying pan, TV, sound equipment is power supply inserting at any time all such as computer especially, and it is surge (peak value) electric current and infringement thereof that the loose contact meeting produces overcurrent, or bigger the losing and the destruction of system etc. of the unexpected especially computer loss of shutting down as data and file.This product is fool proof and convenient because of having solved above-mentioned these problems, and because of magnetic pole adopt strong magnetic alloy make thus very thin very light, only need conventional as fixing the adding of integrated encapsulation, splicing, screw thread or combination is installed on plug and the receptacle face; Series thermal-sensitive resistance is surge (peak value) electric current and harm thereof with regard to gradable anti-overcurrent on arbitrary electrode of plug and socket respectively, also can when excess load or short circuit, cut off the power supply automatically, automatic recovery of power supply again after fault is got rid of, and belong to non-moment Fuse Type outage (lowering the power supply energy earlier and gradually), so no fuse, air, the instant cut-off of almost present all insurances such as electromagnetic type or switchgear and the overcurrent that therefore causes are to the impact of electrical appliance and electrical network, infringement and damage, and this is extremely important, because a host of facts prove a lot of electrical equipment and electronic devices and components such as transistor, the damage of chip etc. is not before occurring in the fuse go, but the surge peak energy that promptly produces therefrom in the moment of blown fuse damages, cause insurance " non insurance " even play damage effect on the contrary, this product is because of the absorption peak energy of thermistor and convert heat energy to and improve self temperature and resistance is increased limit characteristic that electric current increases so no matter it leads to, disconnected can not produce that spark (the contour electric energy of peak value puncture air and produce spark) causes fire and fool proof, and product uses not only very convenient, make and also need not to increase any operation substantially with cost and simple, so its application and market prospects are extremely wide, promptly satisfactorily finish above-mentioned utility model purpose.
