Abstract

The utility model discloses an electric socket and a plug used for communicating an electric appliance and a power. The magnetometric safety electric socket and the plug whose jack is closed conduct the electrical current through the mutual attraction of a magnetic pin and an elastic conduction board in the socket. The hole of the socket is closed by a closing board. When the pin of the plug is not inserted in the jack, the closing board is not provided with electricity and is very safe. Compared with an ordinary electric socket and a plug, the utility model has the advantages of convenient operation and low cost. The electrical contact is reliable. Because of the change of structure, the electric socket and the plug of the utility model is thinner and smaller.

Description

Electric socket and plug

The utility model proposes a kind of electrical socket and plug that is used for connecting electrical equipment and power supply.Especially a kind of electrical safety socket and magnetic force plug that seals jack.

Present normally used electrical socket all is an open type.The pin of plug is column or patch conductor, and the copper card in pin and the socket is pressed by elastic force machinery and touched the conducting electric current.The mode of this conducting electric current is very unreliable, tends to cause loose contact because of contacting to become flexible, even can make the plugs and sockets heating, and sparking is so that cause fire.Also usually take place because of socket copper card tension, and plug is extremely required great effort when inserting socket aperture or transfering to, make troubles to the user.And exposed very dangerous because of the charged copper card in the socket aperture.

The utility model proposes a kind of improved electrical socket and plug.It is more reliable that it utilizes magnetic force that plug is contacted with the electric contact of socket, and make the insertion of plug and transfer to very convenient.And the jack of this electrical socket is in a kind of safe nothing electricity closed state when not inserting plug.

For achieving the above object, the scheme that the utility model is taked is: two pins of plug are conductive hollow cylinder, and cylinder is built-in with magnet.Two jacks of electrical socket are sealed by shrouding fully.Have the iron made from mild steel and inhale the elastic conduction plate and the shrouding maintenance certain interval of piece.When plug base pin contacted with shrouding, the magnetic adhesion by between magnet in the pin and the iron suction piece was pull-in on the shrouding elastic conduction plate and pin in the socket tightly, and by shrouding conducting electric current.When pin left the jack shrouding, magnetic force disappeared, and by self elastic force, the elastic conduction plate is got back to the position that keeps certain interval with shrouding, and this moment, shrouding was not charged, as safe as a house.

The utility model, reliable except conducting electricity, outside the advantages such as safety easy to use, because the improvement of its internal structure makes it just can be to slimming, miniaturization develops, thereby has reduced cost.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

(A) is plug in the accompanying drawing, (B) is electrical socket.In plug (A), constitute shell by (c) with (d), two identical pins (10) are housed on shell (d).The hollow cylinder that this pin is made by sheet copper (4) and its inner magnet (3) are formed.In the pin upper end, be connected with lead (1) with screw (2).

Electrical socket (B) is to constitute shell by panel (e) and base plate (f), has on panel (e) and corresponding two jacks of plug base pin (5), and this aperture, hole is slightly larger than the pin external diameter.In socket, seal jack by copper shrouding (9).Elastic conduction plate (7) is housed below shrouding (9).Elastic conduction plate right-hand member is equipped with iron and inhales piece (8), and conductive plate faces the facet that face has a projection mutually with shrouding.This plane slight inclination, with the shrouding spacing be 1 to 3 millimeter.The conductive plate left end is fastened on the panel (e) by screw (6), and can be by this screw and power line mutually in succession.

When pin insertion jack contacted with shrouding, the magnet in the pin (3) can attract iron to inhale piece (8), forces the elastic conduction plate to lift, and by shrouding (9) and pin adhesive, makes current lead-through.When transfering to plug, pin leaves shrouding, and magnetic force disappears.By elastic conduction plate self elastic force, make it get back to the home position that keeps certain interval with shrouding.This moment, shrouding was not charged.

Claims

1, a kind of electrical socket and plug is characterized in that, the pin on its plug (10) is hollow cylinder (4), and cylinder is built-in with magnet (3).Receptacle sockets is by shrouding (9) sealing, at the flexible conductive plate of shrouding underlying (7).

According to claim 1 described electrical socket and plug, it is characterized in that 2, the end of conductive plate (7) is equipped with iron and inhales piece (8); It faces face mutually with shrouding a protruding inclined plane.This inclined plane and shrouding keep certain interval.
