Automatic alignment plug and socket

Abstract

The invention discloses automatically-registrated plug and socket comprising a plug body and a socket body as well as permanent magnets A matched with the electrodes I, wherein the end part of the plug body is provided with two electrodes I, synonyms electrodes of the permanet magnets A corresponding to the electrodes I are set as synonyms poles, a single round hole is formed on the socket body and is an imbedding hole for the plug body, the bottom of the single round hole is provided with two electrodes II, permanent magnets B matched with the electrodes II, and the synonyms electrodes of the permanet magnets B corresponding to the electrodes II are set synonyms poles. When the plug is close to the single round hole of the socket, the plug and the socket are guided to be in butt joint by virtue of mutual repulsion or attraction of poles so as to complete automatic registration and contact of electrodes. Registration refers to registration of the plug and the socket hole as well as the registration of the electrodes of the plug and the socket. The automatically-registrated plug and socket can be widely applicable to AC power supply coupling of household appliances, thus facilitating use of household appliances for customers and having a good market prospect.

Description

technical field [0001] The invention relates to a combination of a household AC power plug and a socket, in particular to a combination of a plug and a socket with an automatic alignment function. Background technique [0002] Currently widely used household AC power plugs and sockets, the contact mode of the electrodes is side contact, and the common one is the plug-type insertion structure, that is, after the plug of the plug is inserted into the socket, the metal sheet inside the socket clamps the plug. This type of plug and socket is combined by the friction between the electrodes. Therefore, the effective electrode of the plug is required, that is, the plug pin is long enough, and the electrodes of the socket can tightly clamp the electrodes of the plug. However, when the electrode gap of the socket is too small or the elasticity is too large, it is very difficult to insert and pull the plug, and it is inconvenient to use; The plug is easy to fall off from the socket u...

Problems solved by technology

In this situation, for the elderly, people with handicap and people with impaired eyesight, it is still a little complicated to insert plugs and sockets, it takes a long time, and it is very inconvenient to use household appliances.

For example, the Chinese utility model patent whose application number is 200420013807.0 discloses a combination of a magnetically adsorbed plug and a socket. The technical problem to be solved is that the connection between the plug and the socket is relatively tight and it is not easy to fall off. There is no substantial improvement in the convenience of plugging and unplugging, and the time it takes to insert the traditional plug into the socket is not different Big

Moreover, household AC power sockets in all countries in the world are porous structures with more than 2 holes, and the maximum direction size of each hole is less than 10mm. When plugging in, "alignment-conduction-fixing" is required to complete this process. Ordinary people may sometimes be a little inconvenient, and it is even more difficult for special groups such as the elderly with poor movement accuracy, people with handicapped hands and feet, people with impaired vision, and blind people to plug in and connect.
