In order to improve the safety of electricity use, and avoid the danger caused by touching the power socket by mistake. The technology of the known safety socket in the prior art mainly lies in using a shell or a movable element to cover the electrodes connected to the power supply. Only when the jack of the power socket is opened correctly can the power plug be inserted into the power socket.

Although the known safety socket can prevent the power plug from being arbitrarily inserted into the power jack, as long as one of the jacks is opened, the other jack can be opened at the same time. This design is still safe for children. Insufficient, because children often poke any jack with a foreign object, if the two jacks of the power socket are turned on at the same time, due to the two electrodes in the power socket of the general family, one of them is connected to the live wire and the other is connected to the ground wire ( or neutral wire), if a foreign object is accidentally inserted into the electrode connected to the live wire, it will be extremely dangerous.

Therefore, it would be an optimal solution if a safe power socket could be designed because only one of the jacks is inserted and cannot be inserted into it to cause conduction.
