Description

Combination of a rotary plug and socket

technical field

The utility model belongs to the field of electrical components, in particular relates to a combination of a rotating plug and a socket, and more specifically relates to a combination of a plug and a socket which is connected by screw rotation. the

Background technique

Traditional plugs are generally connected through simple plug-in, but many problems will occur, which will cause inconvenience to people's production and life. For example, if the plug is too tight, it is not easy to pull out the plug. If the plug is too loose, the connection may not be smooth, and the circuit is prone to power failure, which will affect the normal use of electrical appliances. The most dangerous thing is that if the jack on the socket is too large, children are likely to stick their fingers into the jack when they are playing, causing electric shock accidents.

In order to improve safety, some people have improved the socket. For example, Chinese patent application number: 200810116670.4, published on January 20, 2010, disclosed a patent document called a safety socket. The invention relates to a safety socket. It includes: a shell with two jacks; a moving plate with two through holes: the moving plate is located below the shell and can move horizontally between a first position and a second position; when the moving plate moves to the second At the first position, the moving plate will close the two sockets of the shell. When the moving plate moves to the second position, the two through holes of the moving plate will correspond to the two holes of the shell: the moving plate can also be in a third position with a Moving between the fourth positions, when the moving plate moves to the third position, the moving plate is close to the casing, and when the moving plate moves to the fourth position, the moving plate is away from the casing; a driving member is used to move the moving plate from the third position When the fourth position is reached, the movable plate is moved from the first position to the second position; a return member is used to move the movable plate from the second position to the first position when the movable plate is moved from the fourth position to the third position. Location. Though this invention can avoid the electric shock accident that children insert inappropriate item into socket and cause. But this invention still has the problem of difficulty in plugging and unplugging, especially inconvenient for the elderly to use.

For the convenience of plugging and unplugging, some people have improved the plug. For example, Chinese patent application number 201210469334.4, published on February 27, 2013, discloses a patent application document named a plug. The purpose of this invention is to provide a The plug is not only safe and easy to plug and unplug, but also has a reasonable structural design. The following technical solution is adopted: a plug includes a plug body, pins connected to the plug body, and wires connected to the pins, the plug body is provided with a through hole for finger insertion, and the side of the plug body is provided with a depression matching the finger, An alignment block is arranged below the wire, and a guide groove matching with the wire is arranged on the alignment block. Although this plug solves the problem that plugging and unplugging is not easy, it still does not solve the problem that the socket easily causes children to get an electric shock and brings potential safety hazards.

Chinese patent application number 201110393565.7, published on March 21, 2012, discloses a patent application document named as an electric shock-proof plug and socket, which discloses an electric shock-proof plug and socket, including a plug and a socket, and the plug includes a plug The body and the electrodes, the socket includes a socket board, the socket board is provided with a jack connected to the power supply through a wire, and the plug socket is provided with an insertion power supply mechanism. In this invention, an insertion power supply mechanism is provided in the plug socket, and the socket is really charged only after the plug is in place and in good contact. Usually, the reed switch is not under the action of magnetic force, the circuit is disconnected, the socket is not charged, the permanent magnet on the plug is installed in the insulating shell, and only after the plug is inserted in place, the permanent magnet will act on the reed switch on the socket. When the contact of the reed switch is closed under the action of the magnetic force, the socket is charged, which has a very good function of preventing electric shock. This patent improves the plug and the socket at the same time, and solves the problem of electric shock prevention. However, this patent not only has the problem of difficult plugging and unplugging during actual use, but also has the problems of complex structure and high cost in manufacture. the
