Abstract

The utility model relates to a surge current-resistant plug and socket, and pertains to the power supply socket and plug field. The utility model consists of a plug and a socket. The plug substantially consists of plug pieces, a wire entry and a thermal resistor, and the socket substantially consists of jacks that correspond to the plug pieces and a thermal resistor. The utility model has the advantages of the safe use of electricity, convenient use, simplicity and practicality, and tremendous application and market prospects by replacing the fuses of the socket and plug widely used at present with two thermal resistors.

Description

Antisurge current plug and socket

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., 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 solved.

Summary of the invention:

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

The technical scheme that its technical problem that solves the utility model adopts is as follows: fixing inserted sheet in the insulation crust of plug, and thermistor is electrically connected with inserted sheet, fixing inserted sheet in the insulation crust of plug, thermistor is electrically connected with inserted sheet.Design respectively on arbitrary electrode of plug and socket series thermal-sensitive resistance, weaken or eliminate surge current and harm and make fuse and use with thermistor, tool repeatedly automatic safe restore electricity function and do not have the scheme of changing fuse trouble and unsafe factor solve above-mentioned serial problem, to avoid or to alleviate its various harm.

The beneficial effects of the utility model are: design respectively on arbitrary electrode of plug and socket series thermal-sensitive resistance just respectively the anti-overcurrent of two-stage be surge (peak value) electric current 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 the thermistor two-stage bypass of connecting respectively on arbitrary electrode of plug and socket and converts the heat energy of heat energy rising self temperature and resistance to, thereby reduction output current, when being raised to design outage temperature, just stop external power supply voluntarily, the temperature of fixing a breakdown up to cutting off the electricity supply drops to just often automatic recovery of power supply again, can do the very high and fuse use very easily of coefficient of safety, 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.
