Description

Automatic contraposition plugs and sockets

Technical field

The utility model relates to the combination of a kind of household AC power plug and socket, particularly a kind of combination that has automatically plug and the socket of bit function.

Background technology

Present widely used household AC power plug and socket, the way of contact of its electrode are the side joint touch, bolt-type insert structure commonly, and namely behind the latch socket of the plug the inside, the sheet metal of socket the inside is clamped latch.This type of plug and socket are to make the combination of the two by its interelectrode frictional force, therefore need the active electrode of plug, i.e. the electrode of latch long enough, and socket can tightly be clamped the electrode of plug., when too little or elasticity was too big when the electrode gap of socket, the plug plug was very painstaking, uses inconvenience; Too big or elasticity too hour when the electrode gap of socket, the situation of loose contact can appear in plug and socket, being subjected to less pulling force or vibration makes the time spent plug and easily comes off from socket, particularly service time is than long plug and socket, show particularly evidently, this situation can badly damaged electrical equipment, and the spy is the electric equipment products of inductive load fully, and most of household electrical appliance belong to inductive load, as refrigerator, air-conditioning, washing machine etc.In addition, the contacting and separate all and realize by mechanical force of this plug and socket, owing to be subjected to the influence of metal fatigue degree and plastic deformation, there is mechanical damage in plug when inserting and extracting socket, its useful life is limited, especially is subjected to the influence that the two connects number of times the useful life of socket.Also because the active electrode of this plug is exposed fully, the user has the possibility of electric shock when the plug plug, and fail safe is relatively poor.

Thus, people design a kind of attraction of the magnet of opposed polarity that relies on through improvement and realize being in contact with one another of plug and socket, because magnetic plug is identical with the attraction that magnetic socket contacts each time, do not change with the number of times of connecting, also be difficult for producing mechanical damage and metal fatigue, thereby connect number of times to there not being influence its useful life.But these improve the structure of all not breaking away from traditional plug and socket, remain plug and be provided with latch, socket is provided with corresponding a plurality of jacks, its improved effect only be with plug be combined with socket tightr, do not break away from the constraint more than the little and jack number of spliced eye.This situation is for the not nimble people and eyesight impaired person of the elderly, trick, and it is loaded down with trivial details that patchplug and socket still show slightly, and the length that expends time in uses household electrical appliance very inconvenient.For example application number is the combination that 200420013807.0 Chinese utility model patent discloses a kind of magnetic adsorption type plug and socket, specifically be at plug and socket the corresponding different permanent magnet of polarity to be set, but the contact electrode of latch shape is set still on the plug and socket, the technical problem that solves only is to connect relative tight at plug with socket contact back, difficult drop-off, convenience operation for plug does not have substantial improvement, and consumed time is more or less the same during with traditional plug insertion socket.And, the household AC power socket of countries in the world all is the above loose structures in 2 holes at present, and the maximum direction size in each hole is less than 10mm, need " contraposition-conducting-fixing " when patching, finish this process and for common normal person, also can show slightly inconvenience sometimes, cause the not nimble special populations such as people, eyesight impaired person and blind person of the elderly, trick of above-mentioned action poor accuracy to peg graft difficult especially.

At above-mentioned deficiency, a kind of adhesive contraposition automatically need be provided, be convenient to peg graft, and back contact stabilization, plug safe and convenient to use and the combination of socket of pegging graft.
