Description
Technical field
The utility model belongs to supply socket field, is specifically related to a kind of multiple spot magnetic control anti-electric shock socket and plug thereof.
Background technology
Current plug and socket is the most common in daily life, prevailing electric accessories, and it is the bridge between electrical equipment and electrical network, and the use of all electrical equipment all can't do without it, and it is most important to household electricity safety.Because the overwhelming majority is all adopt insulator shell to form with the metal contact piece that inside is directly communicated with power supply, interior metal sheet is exposed or do not have groove mechanical door to hide, only have the function connecting electrical network and electric equipment, but not there is inner shutoff device, not there is electroshock-proof function.Once human body by metal object or directly touch, then electric shock accidents can occur, therefore, the report of the electric shock accidents caused by socket particularly children from getting electric shock accident is of common occurrence.Such as conventional jack, does not have electroshock-proof function completely, cannot provide protection.Although occur that electroshock-proof function is limited, mechanical protection door anti-electric shock socket, can provide over cap in receptacle sockets, cannot realize defencive function when sharp-pointed metal object is inserted as machine door protection socket, magnetic control socket etc.Magnetic control machinery or dry-reed tube switch anti-electric shock socket, in most of the cases can both play the effect of isolation receptacle sockets metal contact piece and power supply, but under outside magnetic fields, can produce misoperation, cannot realize defencive function.
Existingly mainly concentrate on the following aspects with anti-electric shock socket Patents and realize: 1, adopt tandem tap device in socket, by the break-make of metal contact piece in switch controlling socket and power supply, by the metal contact piece in receptacle sockets and isolated from power, reach the object of protection against electric shock, but because switch is when forgetting cut out, in receptacle sockets, metal contact piece is charged, easily causes electric shock accidents to occur.2, mechanical protection door anti-electric shock apparatus is adopted; as application number: CN103346424A, a kind of socket protective door of title, describes one and hides receptacle sockets by arranging the door-plate that slidably insulate; prevent metal object from inserting receptacle sockets, reach the object of protection against electric shock.But because metal contact piece in receptacle sockets is failed and isolated from power, mechanical protection door makes it close by means of only spring force, and under external force, the metallic foreign bodies such as pin, key, nail still can insert, and easily cause electric shock accidents to occur.3, magnetic control mechanical switch anti-electric shock apparatus is adopted, as application number: CN20138119Y, a kind of anti-electric shock socket of title and plug, describe a kind of by arranging the magnetic switch device with mechanical linkage, and magnet is embedded in plug, when plug does not insert socket, under the action of the spring, mechanical switch is in off-state, and the metal contact piece in receptacle sockets is not charged; Work as plug insertion socket, the magnetic of magnet makes mechanical switch produce mechanical displacement, and the closing of contact, receptacle sockets is charged, reaches the object of protection against electric shock.But because any carrying magnetic material all will make mechanical device action, as magnetic screwdriver or small magnet etc., easily cause electric shock accidents to occur; In addition, because the factors such as mechanical device is rubbed affect, easily there is poor contact of contacts situation.3, magnetic control dry-reed tube switch anti-electric shock apparatus is adopted, as application number/patent No.: CN201383581Y, a kind of safety socket of title, describe a kind of by two tongue tubes of connecting in socket inlet wire, and magnet is embedded in plug, when plug does not insert socket, tongue tube is in off-state, and the metal contact piece in receptacle sockets is not charged; Work as plug insertion socket, the magnetic of magnet makes tongue tube adhesive, and receptacle sockets is charged, reaches the object of protection against electric shock.But because any carrying magnetic material all will make tongue tube action, as magnetic screwdriver or small magnet etc., easily cause electric shock accidents to occur; In addition, the electric current passed through due to tongue tube is limited, is not suitable for the socket in big current situation.
Utility model content
The utility model is intended to the defect overcoming prior art, a kind of multiple spot magnetic control anti-electric shock socket and electric shock resistant plug thereof are provided, structure is simple, the built-in shutoff device of socket, there is multiple unipolarity Hall switch sensor, under unused state, in receptacle sockets, metal contact piece is not charged, reliably can realize protection against electric shock accident and occur.
The technical solution of the utility model is as follows: a kind of multiple spot magnetic control anti-electric shock socket, comprise jack housing, power line, unipolarity Hall switch sensor, triode, relay, metal contact piece in jack housing jack is connected with zero line with the live wire of power line respectively by relay, multiple unipolarity Hall switch sensor is provided with near each jack of jack housing, by each Hall element sensitive surface induction different magnetic field magnetic pole, produce conducting and cut-off that control signal controls triode, thus drive relay to power to socket.
The cascade of multiple unipolarity Hall switch sensor, the output of previous Hall element is connected with the power cathode of a rear Hall element, the control signal that tail sensor exports controls conducting and the cut-off of triode, thus drives relay, contactor or controllable silicon actuator.
A kind of electric shock resistant plug, comprise with above-mentioned socket with the use of plug, magnetic washer is sleeved on plug, and magnetic washer arranges multiple magnet, and it is corresponding that its magnetic pole and Hall element respond to magnetic pole, a magnet South Pole, a magnet arctic.
When after the plug insertion socket putting magnetic washer, magnet on magnetic washer and Hall element are pressed close to, Hall element senses correct field pole, produce and export, relay closes is driven by triode, the live wire of power supply is communicated with zero line metal contact piece with the corresponding live wire in receptacle sockets with zero line, powers to plug.
Magnetic washer adopts insulating material to make, and magnetic washer size is greater than three and inserts plug size size.
On magnetic washer, the distribution of magnet is corresponding with the position of socket Hall element.
Magnetic washer is that three slotting plugs use or two slotting plugs use.
Magnetic washer is that three slotting plugs and two slotting plugs are used in combination.
Compared with prior art, the utility model has following beneficial effect:
The utility model is simple and reasonable, first be the built-in self closing device of socket, magnetic washer is adopted to be sleeved on plug, highly versatile, cost is low, before the plug being set with magnetic catch does not insert socket, the live wire in receptacle sockets and zero line metal contact piece are all not charged with isolated from power, can effectively take precautions against human body by metal object or directly touch metal contact piece in jack time occur electric shock accidents; Secondly, can, by multiple unipolarity Hall switch sensor identification specific magnetic fields, control reliable, thus the electrocution-proof protection inefficacy preventing from external magnetic field from disturbing causing; 3rd, there is advantage that is stable, reliable and initiatively pre-protection against electric shock.What socket adopted is that plug is first inserted into position, and the mode of just powering after contact is good, effectively prevent spark phenomenon when plugging and unplugging plug.Owing to not adopting mechanical switch, loose contact phenomenon is less likely to occur, socket long service life, performance is good.
