Abstract

The utility model relates to a safety socket and a safety plug and belongs to the field of household electrical appliances. The safety socket comprises two contact sheets and two communication contact points which are respectively connected with a power source. The safety socket is characterized in that two limiting contact points are arranged on the two communication contact points; lower parts of the contact sheets are fixed on an insulating supporting plate; one end of each contact sheet is fixed with a spring through an insulator A, and the other end of each contact sheet is arranged between one communication contact point and one limiting contact point; with the insulating supporting plate adopted as a fulcrum, a lower part of the other end of each contact sheet is fixed with a magnet a through an insulator B; and the magnet a is adjacent to the surface of the socket. According to the safety socket and the safety plug of the utility model, a lever principle is utilized; a spring pull force and an electromagnetic attracting force are respectively designed at two ends of a lever; under normal circumstances, the spring pull force makes the socket be in a power-down state, and energization cannot be realized when any other conductive materials are inserted into jacks; when the safety socket is used, because the electromagnetic attracting force conquers the spring pull force, such that energization can be realized; and therefore, the safety socket is very safe and reliable, and is especially suitable for families with young children.

Description

Safety socket and safety plug

Technical field

The utility model relates to a kind of safety socket and safety plug, belongs to the household electrical appliance field of tool.

Background technology

The used socket of family often is fixed on the body of wall, namely pegs graft with plug and just touches and can switch on, and is very easy to use.But this socket secure of namely inserting electricly is troubling.If family has child, his curiosity may cause fatal harm sometimes.If child inserts aperture in the socket to very thin finger because of carelessness, power connection, he is the possibility that electric shock is arranged; Perhaps his iron rod picking up conveniently or nail insert the aperture in the socket, and the consequence of that electric shock has been well imagined.

Chinese patent application number is " 90103197.6 ", denomination of invention discloses a kind of safety socket for " safety socket unit ", it is by installing the magnet of same magnetic in plug and socket, when the plug insertion socket hole, because magnetic is repelled each other, move on the magnet in the plug, drive on the socket contact and move power connection, when plug is extracted socket aperture, because the magnet in the plug is without magnetic fields, because Action of Gravity Field moves down, the band moving contact moves down, disconnect the contact, therefore namely use electric conducting material to insert in the socket aperture power supply and can not connect, so that socket secure is reliable, non-contact electric is dangerous.But magnet is without the fixed position in this invention, and the action that moves on it, moves down may be lost efficacy sometimes, causes safety socket possibility or dangerous.

Summary of the invention

For the deficiency in the above-mentioned field, the utility model provides a kind of safety socket and safety plug, be difficult for producing Problem of Failure, and safe and reliable.

Safety socket, comprise two contacts, two that link to each other with power supply respectively are communicated with the contact, it is characterized in that: two are communicated with the top, contact two spacing contacts are arranged respectively, described contact below is fixed on the insulation support plate, one end of contact is fixed with spring by insulator A, and the described contact other end is being communicated with the contact and is limiting between the contact; Take insulation support plate as fulcrum, the below of the contact other end is fixed with magnet a by insulator B, the contiguous receptacle face of described magnet a.

Described two contacts are parallel, are fixed on same insulation and go up in flakes, and described two connection contacts are contour, and two spacing contacts are contour.

Described insulator B is insulated tension pole, and an end face of described insulated tension pole is fixing in flakes with insulation, is fixed with magnet a on another end face.

Safety plug comprises two slotting pawls, it is characterized in that: be fixed with a magnet b in plug inside, when slotting pawl inserted above-mentioned safety socket, magnet a and magnet b were contiguous.

Described magnet a and magnet b are positioned at the upper-lower overlapping position.

The utility model is namely inserted to such an extent that electric dangerous mode is revised as by the mechanical lever principle and realizes that when not needing to switch on, the contact other end lifts, away from the contact with original; When the needs electricity consumption, the contact other end moves down, and the contact contact gets electric, and the object on lever principle both sides or strength then realize by pulling force and the electromagnetic attraction of spring.With contact as lever, insulation support plate is fulcrum, and the one end is a tensioning spring, and the other end is magnet a, under normal conditions, because the pulling force of tensioning spring, contact one end lifts, and contacts with spacing contact, no power, when having other electric conducting material to insert jack, socket no power, lever keep original position motionless; When safety plug of the present utility model inserts, produce attraction between magnet a and the magnet b, this attraction overcomes the pulling force of spring, and contact is contacted with being communicated with the contact downwards, makes the plug energising, thereby makes the electrical equipment that connects safety plug get electric.

Be to reduce raw material, the utility model is fixed together two contacts, and the action of two contacts is synchronous, flick simultaneously, simultaneously electric.

The material of using of the present utility model, except guaranteeing that connection contact, contact are the electric conducting material, other material is preferably all used the insulation material, advances certain really safety of artificial delivery product.

The utility model utilized lever principle, designed respectively mutually suction of spring tension and electromagnetism at the two ends of lever, and under normal conditions, spring tension makes socket be in off-position, and other any electric conducting material inserts jack and all can't switch on; During use, overcome spring tension by electromagnetic attraction, thus must be electric, very safe and reliable, be specially adapted to child's family.
