Description

A kind of novel adsorption safety waterproof permanent magnetism plug and socket

Affiliated technical field

The utility model relates to a kind of novel adsorption safety waterproof permanent magnetism plug and socket, and especially not water funk spattering is not afraid of touch, is not afraid of dust, the hermetically sealed safety plug and the socket that can clean.

Background technology

At present, known plug is made up of insulation crust, electric wire and metal contact, and socket is made up of the insulation crust that has jack, electric wire and metal spring sheet.When the metal contact of plug is passed through the jack insertion metal spring sheet centre on socket insulation crust surface, can produce electric spark because contact is bad, especially in use have under the situation that water spatters, be easy to cause short circuit phenomenon even initiation fire, more likely initiation fire even blast when meeting fuel gas; Children also stretch into finger on the spring leaf of socket inside by the jack of socket easily, form path by human body and the earth it is caused the accidental shock injury.

Summary of the invention

In order to eliminate the potential safety hazard that existing plug and socket brings, the utility model provides a kind of hermetically sealed permanent magnetism plug and hermetically sealed socket of safe waterproof, and not water funk spattering is not afraid of touch, is not afraid of dust, safety plug that can clean and socket.The technical scheme that its technical problem that solves the utility model adopts is: the permanent magnetism contact is embedded in the insulation crust surface of plug, the surface of one end and insulation crust remains on the same level, the other end links to each other respectively with electric wire in insulation crust inside, electric wire is derived by the wire hole of plug, the shape of permanent magnetism contact can be cylindrical also can be cube.Two sheet metals of adhesion on the insulation crust of socket, the shape of these two sheet metals both can be square also can be circular, the upper surface of its upper surface and insulation crust is fair, lower surface exposes in the insulation crust volume inside.Insulation crust inside has two insulating supports to support two metal contact pad respectively, metal contact pad links to each other with insulating support, hard contact is all arranged at the top of two metal contact pad, two metal contact pad are insulated dividing plate and separate, the end of two metal contact pad connects electric wire respectively, the wire hole of electric wire by socket derived, the following spring that all is fixed with of two metal contact pad, and the hard contact at two metal contact pad tops is corresponding with the position of two sheet metals above the socket insulation crust.The hard contact at metal contact pad top and metal contact pad are one, but hard contact is a slug that raises up, and contact with the lower surface of sheet metal above the insulation crust to make things convenient for it.During use, two permanent magnetism contact correspondences of plug are placed on two sheet metals above the socket insulation crust, and hard contact by inner corresponding two the metal contact pad tops of sheet metal absorption socket, after the hard contact at metal contact pad top is adsorbed link, electric current finally arrives electrical appliance by metal contact pad, hard contact, the sheet metal above the socket insulation crust, the permanent magnetism contact of socket inside.When not using, pull out plug, two permanent magnetism contacts on the plug separate with two sheet metals above the insulation crust, owing to lose the suction-operated of permanent magnetism contact, the hard contact at two metal contact pad tops of sheet metal above the socket insulation crust and socket inside separates, and metal contact pad is fixed on the springs return original position under it.Like this, the sheet metal above the insulation crust has not just had voltage yet, makes the socket outside be in a kind of no-voltage safe condition, even touch, water spatters, and it also all is safe cleaning.

The beneficial effects of the utility model are, in convenient the use, have strengthened fail safe greatly, even touch, water spatters, cleans all is safe, and also simple in structure, with low cost, help promoting the use of.

Among the figure, 1. electric wire, 2. the permanent magnetism contact of plug, the 3. insulation crust of plug, 4. the insulation crust of wire hole 5. sockets of plug, the 6. sheet metal above the socket insulation crust, 7. wire hole 8. insulating barriers of socket, 9. hard contact, 10. insulating support, 11. metal contact pad, 12. springs.

Embodiment

In Fig. 1, electric wire 1 connects two permanent magnetism contacts 2 respectively in the insulation crust 3 of plug, and electric wire is derived by the wire hole of plug.

In Fig. 2, the sheet metal 6 above the insulation crust sticks on the insulation crust 5 of socket, and the wire hole 4 of socket uses for deriving internal wire.

In Fig. 3, insulation crust 5 inside of socket have two insulating supports 10 to support two metal contact pad 11, metal contact pad 11 tops are separated by insulating barrier 8 in the middle of 9, two metal contact pad of hard contact 11 are arranged, and the metal contact pad 11 terminal electric wires 1 that connect are derived by the wire hole 4 of socket.

In the embodiment shown in fig. 4, insulation crust 5 inside at socket, insulating support 10 support metal touch panels 11, the metal contact pad 11 terminal electric wires 1 that connect, be fixed with spring 12 below the metal contact pad 11, the hard contact 9 at metal contact pad 11 tops is corresponding with sheet metal 6 positions above the socket insulation crust 5.During use, two permanent magnetism contact 2 correspondences of plug are placed on two sheet metals 6 on socket insulation crust 5 surfaces, two permanent magnetism contacts 2 adsorb the hard contact 9 at inner corresponding two metal contact pad 11 tops of sockets by the sheet metal 6 on the absorption socket insulation crust 5, after the hard contact 9 at metal contact pad 11 tops is adsorbed link, electric current passes through metal contact pad 11, hard contact 9, sheet metal 6, the permanent magnetism contact 2 above the socket insulation crust 5 of socket inside, finally arrives electrical appliance.When not using, pull out plug, two permanent magnetism contacts 2 on the plug separate with two sheet metals 6 above the socket insulation crust 5, owing to lose the suction-operated of permanent magnetism contact 2, sheet metal 6 above the socket insulation crust 5 separates with the hard contact 9 at two metal contact pad 11 tops of socket inside, the spring 12 that metal contact pad 11 is fixed under it retracts original position, thereby makes socket integral body be in the no-voltage safe condition.
