Socket and plug

Technical Field

More specifically, the application provides a safety socket and a plug matched with the safety socket, and the safety socket is a socket without a jack and a plug matched with the socket, can greatly reduce the occurrence of safety accidents, and has higher application value.

Background

The connection between the plug and the socket is the most common power supply mode of an electric appliance in daily life, and is widely applied to the daily life of people. The existing connection mode of the plug and the socket is as follows: the inserting pieces on the plug are inserted into the socket through the inserting holes, and the inserting pieces are in clamping contact with the conductive copper sheets in the socket, so that current conduction between the plug and the socket is completed.

Due to the existence of the jacks on the socket, great potential safety hazards are brought. For example, when used in a kitchen, water is likely to enter the jack, which may cause a short circuit and cause a fire or other safety accident. Meanwhile, due to the existence of the jack, when children insert foreign matters into the jack, the possibility of electric shock danger exists. Although the existing socket adopts the design of a safety door to prevent foreign matters from being inserted into the socket. However, the adoption of the safety door on the socket increases the production cost of the socket and is difficult to assemble. In addition, due to the design of the safety door on the socket, the plugging and the pulling are inconvenient, and the service life is greatly reduced.

Further, the production and manufacturing costs are too high due to the presence of the clamping copper in the socket. In addition, because the plug and the socket are in clamping contact, when the socket is used for a period of time, a clamping copper piece in the socket is easy to loosen, poor contact, ignition and other phenomena are caused, and safety accidents are possibly caused.

Therefore, a new socket is urgently needed to solve the above problems.

By adopting the structure, when the permanent magnet is close to or contacts with the conducting strip, the conducting strip can be directly conducted with the metal core of the second lead. When the end of the metal core is parallel to or protrudes out of the exposed end surface of the permanent magnet, the permanent magnet is mainly used for realizing the opening and closing of the magnetizer relative to the conducting strip, and the metal core is used for realizing the current conduction with the conducting strip; when the metal core is connected with the conducting sheet only, the permanent magnet has the function of realizing the opening and closing of the conducting sheet and conducting current.

In summary, when the plug contacts the conducting strip on the socket, due to the attraction effect of the permanent magnet on the magnetic conducting piece, the magnetic conducting piece can overcome the elastic force of the elastic connecting piece and cling to the conducting strip, so as to complete the current conduction between the magnetic conducting piece and the permanent magnet, and thus the current conduction between the socket and the plug is completed. When the plug moves away from the conducting plate, the elastic connecting piece restores to the original state, and the magnetic conducting piece leaves the conducting plate and forms a certain gap with the conducting plate under the driving of the elastic connecting piece; at the moment, the conducting strip is not electrified, and the touch conducting strip can not be shocked by electricity, so that the safety protection effect is achieved. The current conversion device can be widely applied to places needing current conversion, such as socket banks, wall sockets and the like.
