Abstract

A matched electric-shock prevention power socket mainly comprises an ordinary power socket, a matched board, an electromagnetic relay, a tongue tube with normally-open contacts and a permanent magnet, and the like. When the matched board with the permanent magnet is not close to the tongue tube in the power socket, the contact of the tongue tube is not closed, a coil of the relay can not electrically work, moving contacts and fixed contacts of the relay are also not closed, a live wire and a zero wire of the commercial power is mutually connected with two moving contact of the relay, therefore, the left fixed contact and the right fixed contact of the relay can not be charged; and two fixed contacts of the relay is mutually connected with a left inserting sleeve and a right inserting sleeve of the power socket, therefore, the left inserting sleeve and the right inserting sleeve of the power socket are not charged, and the power socket is safe and has low probability of electric shock, when the matched board with the permanent magnet is only close to the tongue tube in the power socket, the spring leaf in the tongue tube is magnetized, the contacts are pulled in, the coil of the relay can electrically work, the moving contacts of the relay and the fixed contacts thereof are closed, the fixed contacts, the left inserting sleeve and the right inserting sleeve of the power socket obtain electricity, and the power plugs of the used electric apparatus also can ensure electricity extraction.

Description

The supply socket of supporting formula protection against electric shock

Affiliated technical field

The utility model relates to a kind of supply socket, a kind of supporting formula protection against electric shock supply socket of saying so more specifically.

Background technology

Along with improving constantly of people's living standard; electrical appliance is more and more; the demand of supply socket is also followed more and more; safety problem also seems and more and more payes attention to; and common its disadvantage of supply socket does not have reliable shock preventing protector of electric at present, as improper use or the careless slightly electric shock accidents that very easily takes place.

Summary of the invention

In order to overcome the deficiency of common power socket, the purpose of the utility model design is exactly effectively to avoid a kind of supporting formula protection against electric shock supply socket of getting an electric shock.

The technical scheme that its technical problem that solves the utility model adopts is: it mainly is made up of common power socket, relay, tongue tube and mating plane.Wherein tongue tube is a two-man act sheet normal opened contact formula tongue tube, near the position of electric socket panel below, and the center between the sleeve hole, two left and right sides on the electric socket panel; Relay is two groups of moving fixed contact electromagnetic type relays, is fixed in the supply socket, and the left moving contact of its repeat circuit and the zero line of civil power join; The live wire of right moving contact and civil power joins; The left fixed contact of relay and the left sleeve of supply socket link to each other, and the right fixed contact of relay and the right sleeve of supply socket link to each other, and the two ends of relay coil link to each other with the zero line of civil power and the upper reed plate of tongue tube respectively; The following reed of tongue tube links to each other with the live wire of civil power; Centre bit on the mating plane be equipped with a permanent magnet and about the latch film perforation of two symmetries, attaching plug for electrical appliance inserts, wherein permanent magnet is encapsulated in the plastics the inside of mating plane or otherwise is fixed under the face of mating plane, and about on the mating plane center between two latch film perforations; The size of two left-right symmetric latch film perforations is identical with two sleeve holes on the electric socket panel with position distribution on the mating plane, thereby can make electrical appliance attaching plug about two plug blades insert smoothly in two latch film perforations on the mating plane, earlier the attaching plug of electrical appliance is inserted in two latch film perforations of mating plane during use, and then in the sleeve of two plug blades insertion supply sockets of electrical appliance attaching plug, mating plane just can be near the panel of supply socket like this, because permanent magnet is the center between two latch film perforations about on the mating plane; Tongue tube is the center between the sleeve hole, two left and right sides of electric socket panel; Permanent magnet in the mating plane is just just in time aimed at and near the tongue tube of electric socket panel below like this, reed in the tongue tube is magnetized, the contact of tongue tube reed induces opposite polarity magnetic pole, opposite pole attracts each other, when the magnetic force that attracts surpasses the elastic force of reed, contact will adhesive, when the contact adhesive of tongue tube, the live wire of civil power will be delivered to an end of relay coil by the contact in the tongue tube, and the other end of relay coil be directly and the zero line of civil power join, so the coil of relay gets electric work, thereby make the left and right moving on relay both sides, the fixed contact closure, because of the left and right moving contact of relay is respectively zero line and the live wire that connects civil power, so two fixed contacts of relay also will be connected the zero line and the live wire of civil power, again relay about two fixed contacts join with two left and right sides sleeves of supply socket respectively, so two sleeves of supply socket this moment will get, thereby the attaching plug of having realized electrical appliance can make electrical appliance get electric work to the process of supply socket power taking.Otherwise when the attaching plug of electrical appliance is pulled out, this moment, mating plane left the panel of supply socket together with the attaching plug of electrical appliance, make the tongue tube of electric socket panel below lose magnetic field, and two spring contacts that make tongue tube reset and separate, the coil losing electricity of relay and quitting work, about two moving fixed contacts and reset and be in normally open, about two fixed contact dead electricity, two left and right sides sleeves of supply socket are dead electricity also, so this moment, the left and right sides sleeve with the conductor insertion supply socket of what specification all was very safe, that is to say not charged, thereby reached the order ground of protection against electric shock.The utility model is simple in structure, utility model, and steady quality, safe and reliable.
