Description

Magnetic plug and socket
Technical field
The present invention relates to a kind of magnetic plug and sockets, belong to power supply and connect equipment.
Background technique
Attaching plug and socket are that the common electrical equipment and design of residence of power interface are provided for household electrical appliance It is middle using more electric attachments, it and people's life have very close relationship.Existing socket typically directly with power supply Connection, directly contact or foreign matter, which enter, often causes accident, and especially child's curiosity is strong, is easy to fill in various articles slotting Seat, leads to defective socket, even results in electric shock, causes accident.
There are two types of common safeguard measures: one, being protected, but still deposited using increase outer cover or using the mode of cover board A possibility that external metal device directly contacts power supply, and needs to open repeatedly in use process, closes outer cover or cover board, It is extremely inconvenient for a user;The connection of socket and power supply is disconnected using the form of extra switch, common manual switch is mostly Slider type and microswitch type, although opening ways are more convenient than outer cover and cover board, there is still a need for user's operation bidirectional, automatic switch Due to the electrical equipment particularity of attaching plug and socket, magnetic automatic switch is mostly used in recent years.
Currently, on the market gradually popular at home and abroad using magnetic force as the plug and socket of protective switch, commonly Technological means is as follows:
Chinese Patent Application No.: a kind of 201120568781.6 magnet pin controlling power source sockets, structure have power supply line and insert Bore, its main feature is that the suitable position of panel has a magnet placing area, the suitable position inside socket is fixed a fine motion and is opened It closes, the contact of microswitch burn-ons a piece of iron sheet conducive to induced magnet, and magnet is placed on magnet placing area when use, and magnet is drawn onto micro- The contact of dynamic switch, microswitch reaction power on, and take magnet away, microswitch contact, which bounces, cuts off the power.This is practical new Type controls the power supply line on-off of socket by magnet, and structure is simple and durable, and good reliability maintenance is easy, and is suitble to industrialization, very well Ground solves the problems such as control child sees TV computer.The microswitch of 15A250V, the magnetic used can be selected in the utility model Iron be 3000 Gauss of magnet strength or more than strong magnet, general magnet is not all right.
Above-mentioned patent using magnetic force as the unlocking condition of manual switch, it is possible to prevente effectively from because maloperation or children because It is turned on the switch for curiosity, and then causes accident, then manual switch, and need special unfolding mode, just in case magnet loses, Switch can not just be opened, extremely inconvenient for a user.
Chinese Patent Application No.: a kind of 201110388954.0 safety sockets, the back side of panel set there are two mutually separate The lever arm equipped with iron core, there is binding post in lever arm one end, and the other end has plating corresponding with the phase line jack of socket respectively Silver contact has spring between lever arm and panel.The invention further include with the matching used plug of safety socket, pawl is inserted on plug Root is equipped with magnet corresponding with the iron core on receptacle back lever arm.The present invention is used as household socket or other normal pressures supply Electricity, plug insertion, circuit are connected, and after plug is transferred to, the jack on socket is not charged, even if touching there will not be danger.
Above-mentioned patent is using magnetic force as the unlocking condition of automatic switch, and when use does not need the operation bidirectional of user, only Matched plug need to be inserted into;However, since lever arm is radially movable along plug core, so zero curve and firewire must divide Not She Zhi a lever arm, need bigger activity space, structure is also not compact enough.
A kind of Chinese Patent Application No.: 201410239840.3 magnetic sockets, comprising: jack body, guide rail, bracket, bullet Spring, magnet and electrical contact are provided with guide rail in the jack body, and bracket, cradle back setting are provided on the guide rail There is spring, the spring other end is connected on jack body, and bracket center is provided with magnet, and bracket two sides are provided with electrical contact. By the above-mentioned means, the invention magnetic socket has, unfailing performance is high, easy to use, compact-sized, dustproof electric shock preventive, service life It is long, it is cheap the advantages that, while having extensive market prospects in socket market.
For above-mentioned patent using using magnetic force as the unlocking condition of automatic switch, when use, does not need the operation bidirectional of user, It only need to be inserted into matched plug, while two electrical contacts are each attached on bracket, bracket is in sliding rail along plug core Axial activity, structure are more compact;However, since bracket needs to drive electrical contact activity whole in socket, for magnet Requirement load it is larger, it is necessary to using magnetic strong, big more demanding of suction.
Therefore, shortcoming of the developer according to all kinds of magnetic sockets on the market, especially Chinese application number: Further improvement is made on the basis of 201410239840.3, and a kind of compact-sized, small magnetic plug of magnetic force load is provided And socket, and according to the demand of different clients, further the firmness of significant increase its leakproofness and combination, allows to Still normal use under underwater or severe dust atmosphere.
Summary of the invention
