Abstract

The plug is composed of insert pieces, wire orifice, voltage sensitive resistance, thermistor, and adsorption magnetic pole. The socket is composed of jack corresponding to insert pieces, voltage sensitive resistance, thermistor, and fixed magnetic pole. The invention installs heterologous permanent strong magnets to plug and socket common used currently to increase fixing force in order to guarantee correct and stable connection between electrical source and each pole of electrical appliance. Voltage sensitive resistance bypasses surge voltage, and thermistor absorbs, blocks off surge current so as to resist surge electrical energy. Being instead of fuse, the thermistor can automatic recover power supply safely. The invention possesses features of using electricity safely, convenient use, and wide foreground for application and market.

Description

Antisurge, stable and convenient joining plug and socket with own fuse

Technical field:

The invention belongs to confession, electricity consumption socket and plug field.

Background technology:

Because of power network fluctuation, thunderbolt even power electricity are costed power for illumination, and to cause serious accident such as huge electric energy impact failure electrical equipment such as surge voltage and consequence be not rarely seen, surge electric energy that the frequent switch of especially frequent power network fluctuation and various electrical equipment and plug and receptacle accepts produce and electromagnetic destruction are hard to guard against especially with interference, as bulb, fluorescent tube, the life-span that switches such as computer once lose was equivalent to use continuously 2-10 hour even more, a lot of in addition electrical equipment such as refrigerator etc. mainly are the on-off circuits that patches by plug and socket, TV, though air-conditionings etc. have remote controller, but remote controller is fragile, lose also and must control by switch, the more important thing is in fact grown the switching time of many electrical equipment also can damage and by plug and receptacle accepts control also not within minority, and plug and socket and often patch because of former thereby loose contact such as loosening, frequently produce the surge electric energy especially and damage electrical equipment, easily therefore damage compressor and scrap as refrigerator etc., change trouble after the blowout and be prone to replacing fuse lack of standardization and cause the uneasy congruent hidden danger of electricity consumption, these problems all should be paid much attention to and be properly settled.

Goal of the invention:

The object of the invention designs a kind of Antisurge, stable and convenient joining plug and socket with own fuse exactly, with solve above-mentioned because of inevitably repeatedly switch, plug and receptacle accepts and loose contact and power network fluctuation, thunderbolt frequently produce surge voltage and surge current and change fuse cause electricity consumption dangerous with Electrical Safety potential problem such as inconvenience.

Technical scheme:

The present invention design respectively on plug and socket with permanent strong magnetic pole of the opposite sex and absorption or the prompting of repulsion magnetic force and accurately patch and increase bed knife, prevent the incorrect loosening loose contact that reaches that patches or patch mutually thereof; Piezo-resistance in parallel and series thermal-sensitive resistance on the electrode of plug and socket respectively, weaken or eliminate surge voltage and harm, absorb surge current and energy thereof and convert to thermistor and self temperature and resistance are raise and reduce or the heat energy of blocking-up electric current output weakens or eliminates surge current and harm and make fuse and use with the bypass effect of piezo-resistance, tool automatic safe repeatedly restores electricity function and does not have the scheme of changing fuse trouble and unsafe factor and solve above-mentioned serial problem, avoid or alleviate various harm.

Now main scientific and technological principle and the innovation with its foundation is that advantage is described below:

Permanent ferromagnetic substance that the present invention design fixed magnetic pole on the surface that present widely used plug and socket contact with each other is different such as rare earth magnetic steel etc., make plug and socket by means of the powerful magnetic force of attracting each other add strong fix and fastening ability ensure electrode patch correct with contact well, this is than present draw-in groove, nearly all fixing means such as screw socket is more convenient, especially smooth direct dismounting the in laborsaving timesaving than causing the more surge of manying electric energy destruction of damage and loose contact or loosening generation by fixing in the expansion at present because of plugging to require great effort artificially acutely to shake, 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 and hardware 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; Respectively on the electrode of plug and socket piezo-resistance in parallel and series thermal-sensitive resistance just respectively anti overvoltage be that surge (peak value) voltage and overcurrent are surge (peak value) electric current and infringement thereof; 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 over-voltage and over-current 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 the bypass of piezo-resistance and thermistor and convert heat absorption to self temperature and resistance are raise; when being raised to the outage degree, cut off circuit voluntarily; only need this moment of short duration powered-down or electrical appliance switch to wait for that resistance falls in the thermistor auto-radiating; automatic recovery of power supply ability when dropping to normal degree; only need close a switch again and connect circuit with regard to automatic recovery of power supply; power-off protection when overload or short circuit mechanism is identical with principle and need not and change fuse; and fault (overload or short circuit etc.) reason can not restore electricity before not getting rid of; promptly necessary first disconnecting power switch is to cut off electrical appliance; also cutting off simultaneously the thermistor power supply makes it stop heating and lower the temperature just can restoring electricity again; not that moment is disconnected; so power supply is no surge voltage and surge current; these factors have been strengthened confession greatly; the Electrical Safety coefficient; so no matter be that power supply or electrical appliance comprise the logical of loose contact; the disconnected spark (the contour electric energy of peak value puncture air and produce spark) that can not produce; be the inconvenience that power supply or electrical appliance overload can not produce fire and replacing fuse; more can not cost power line etc. because of power supply such as illumination damages electrical appliance (this class situation is report and often endanger wide often; suffer heavy losses) so fool proof; product uses very convenient; make and also need not to increase operation substantially with cost and simple, so its application and market prospects are extremely wide; promptly satisfactorily finish the foregoing invention purpose.
