Abstract

The present application proposes a safety socket, comprising a shell and two metal electrodes, an elastic member, a movable member and two elastic conductors arranged in the shell. The shell has two sockets and a through hole located between the two sockets. The two metal electrodes correspond to the two sockets respectively. The elastic member abuts against one end of the movable member so that the other end of the movable member protrudes out of the shell through the through hole. When the plug is inserted into the two sockets, the other end of the movable member will be pushed into the through hole, and the expansion portion located between the two ends of the movable member will push against the two elastic conductors so that the two elastic conductors contact the two metal electrodes respectively. Since the two elastic conductors are electrically connected to the external power supply, the safety socket will be in a power-on state at this time. Once the plug is partially unplugged or completely unplugged, the safety socket will be in a power-off state.

Description

safety socket

technical field

A receptacle, especially a safety receptacle that maintains a disconnected state when the plug is not fully inserted.

Background technique

The traditional power sockets used in most households are often deliberately arranged in less conspicuous places or at lower positions for the sake of visual aesthetics in interior design. For example, the power outlets used in most households are mostly set on the wall several centimeters to 30 centimeters above the ground, so they are located in a position that is easily touched by young members of the family. The most common case is that a young member of the family, driven by curiosity, inserts a foreign object into the socket of the power socket. If the foreign object is made of conductive material, it may cause an electric shock accident to the young member.

A common protective measure is to insert a plastic protective cover with a plug-like structure into the power socket. However, this will cause the user to remove the plastic protective cover every time the power socket is used, and it must be replaced after use. It is inconvenient for the user to re-insert the plastic protective cover. Moreover, the plastic protective cover can be easily removed by hand. Once the plastic protective cover is removed, the socket of the power socket will still be exposed, and young members may still be in danger of electric shock.

Another common protective measure is to seal the entire power socket with a plastic cover. However, this will also cause the user to lift the plastic protective cover every time the power socket is used. After use, it must be reinstalled. The plastic protective cover is closed, which is inconvenient for users. Moreover, the young members may still use the plastic cover by themselves. Once the plastic cover is lifted, the young members may still be in danger of electric shock.

In addition, when the plugs of electrical appliances are not fully inserted into the power sockets, especially high-power electrical appliances, it is easy to cause the plugs to heat up and melt during use, and even cause casualties or heavy property losses.

Or when the plug 21 of the electrical appliance 2 is not fully inserted into the safety socket 1, the same electrical appliance 2 cannot obtain power to operate, and then there is no need to worry that the plug 21 will be overheated and melted to cause a disaster.

Another effect that the safety socket described in the above embodiments can achieve is that since the insulation skin colors of the live wire and the ground wire of the mains power supply are not uniform, it is not 100% sure which is the active wire only from the skin color of the wire. Which is the live wire for power supply, and which is the ground wire for no power supply. That is to say, once the power socket is installed, even the electrician who originally installed it cannot clearly judge with the naked eye which socket is connected to the live wire with power supply and which socket is connected to it without measuring the electric meter. Connected behind the jack is a ground wire without power supply, let alone a general user. In the embodiment of the present application, the two jacks are all in the disconnected state, so no matter how the socket is installed at the beginning, there is no need to worry about electric shock due to the insertion of conductive foreign objects into the jacks.

Although the technical content of the present application is described above with the embodiment having two jacks, for those skilled in the art, it can be easily transferred to the three-hole socket according to the teaching of the above embodiment, Because the third hole of the three-hole socket is only used to guide the leakage current of electrical appliances to the ground wire, not the ground wire and live wire that constitute the entire electrical circuit. In addition, those skilled in the art can easily transfer the teachings of the above embodiments to the socket of the extension cord.

To sum up, the present application has disclosed the above with preferred embodiments, but it is not intended to limit the present application. Anyone who is familiar with the art and makes some changes and modifications without departing from the spirit of the present application should be included in the present application. Within the scope of this application, the scope of protection of this application should be defined by the scope of the appended patent application.
