Description

Rare earth permanent magnet attaching plug and socket

Technical field

The utility model relates to a kind of attaching plug and socket, the attaching plug of the rare-earth magnet that especially a kind of inside is arranged and socket.

Background technology

At present, the connected mode of known plug and socket is all insert in socket by the sheet metal on plug, by contacting with the sheet metal in socket the object reaching and switch on power, mainly can two problems be there is in this plug and socket in the process used, one be the number of times of plug or unplugg too much time socket inside sheet metal can fluff, will loose contact when after fluffing, plug and socket connects, impact uses, and two is that plug easily comes off inside socket when there being people to move plug cord.

Summary of the invention

In order to overcome the problem that existing socket and plug easily fluff and come off in the process used, the utility model provides a kind of rare earth permanent magnet attaching plug and socket, the connecting portion of this socket and plug is circular, position corresponding on socket and plug is all provided with rare-earth magnet, make the connection between socket and plug more stable by this design, difficult drop-off, also can not cause the situation of socket and plug loose contact because of often using socket.

The utility model solves the technical scheme that its technical problem adopts: the position that socket and plug connects is designed to circular projection and sunk structure, the circular bulge-structure of socket is made up of plastic material, the bottom of two circular depressed area of socket is separately installed with two metallic conduction joints, the bottom surface of conductive contact eminence seating depression structure, one end of conductive contact is bolted on the back side of socket, there is a protruding plastic cylinder body structure in the centre of socket, cylindrical center has one to lead to receptacle back for connecting the metal joint of ground wire, cylindrical top is fixed with the rare-earth magnet of 4 pieces of toroidals, and four blocks of magnet are mutually 90 degree of arrangements, and S pole, N pole is arrangement alternately, after plug insertion socket, synonyms pole is attracting, the additional force that magnet applies can be there is between contact point, make to combine between contact point more fastening.

One end of plug is the circular ring be made of plastics, the inside of plug has two to have metal circular bulge-structure, the middle part of plug core depressed area has one for inserting the metal shaft of earth connection point in receptacle center hole, the outside of metal shaft is provided with 4 block system magnet, the arrangement position of rare-earth magnet with S pole, N pole towards identical with the magnet on socket, socket and plug can be enable so to be better fixed together by the suction of magnet, and one end of plug is provided with one for rotating the knob of plug inside magnet.During use, the circular boss of plug is inserted inside the circular depressed area of socket, at this moment two circular metal structures on plug will two metallic conduction junction contacts conveniently with socket bottom circular depressed area, the metal shaft of plug core is inserted the aperture inside of receptacle center and is connected with underground metalliferous joint, when plug insertion socket inside, four blocks of magnet on plug can contact with four blocks of magnet corresponding on socket, now plug and socket will by magnet adsorption together, need the knob rotated during unplugg on plug, the magnet of plug inside can be rotated during turning knob, the magnet of plug inside can be relative with the magnet homopolarity of socket inside in the process of rotating, thus the thrust that generation one is outside, so just can easily plug be pulled out.

The beneficial effects of the utility model are, can be linked together closely by plug and socket by the rare-earth magnet of socket and plug inside, use more convenient, useful life is longer.
