Abstract

The utility model relates to a surge voltage proof socket and plug, which belongs to electric plug and socket territory and comprises a sheath, a wire faucet, a socket comprising a voltage dependent resistor as the master structure and a socket comprising a faucet corresponding to the sheath and a voltage dependent resistor as the master structure. The utility model makes the extensively employed socket and plug into two stage voltage dependent resistor peak clipping surge voltage proof, which is safe in electric employment, convenient in use, simple in operation, which is in no need of adding process and of extensive value.

Description

Plug and socket of anti surge voltage

Technical field: the utility model belongs to power supply base 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., these problems all should be paid much attention to and be properly settled.

Summary of the invention:

The purpose of this utility model provides a kind of plug and socket of anti surge voltage, and is above-mentioned because of inevitably switch, plug and receptacle accepts and loose contact and power network fluctuation, thunderbolt frequently produce the uneasy congruent Electrical Safety potential problem of surge voltage electricity consumption repeatedly to solve.

The technical scheme that its technical problem that solves the utility model adopts is: in the insulation crust of plug, an end of piezo-resistance is electrically connected with an electrode of plug, the other end of piezo-resistance is electrically connected with another electrode of plug; In the insulation crust of socket, an end of piezo-resistance is electrically connected with an electrode of socket, the other end of piezo-resistance is electrically connected with another electrode of socket.The utility model design respectively on the electrode of plug and socket the scheme of piezo-resistance in parallel solve above-mentioned serial problem, to avoid or to alleviate its various harm.

The beneficial effects of the utility model are: design respectively on the electrode of plug and socket piezo-resistance in parallel just respectively the two-stage anti overvoltage be surge (peak value) voltage and to the infringement of electrical appliance, air, the instant cut-off of almost present all insurances such as electromagnetic type or switchgear all causes the impact of overvoltage to electrical appliance and electrical network, infringement and damage, 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 to occur in the insurance outage as before the blown fuse, 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 weakens peak energy because of piezo-resistance two-stage bypass in parallel respectively on two electrodes of plug and socket, coefficient of safety is very high, so no matter be that power supply or electrical appliance are logical, disconnected can not produce spark (the contour electric energy of peak value puncture air and produce spark) and fool proof, and product uses not only 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.
