Background technique

In order to avoid potential safety hazards, the current sockets are generally equipped with a protective door for covering and blocking the electrodes of the socket. Objects protruding into the socket and contacting the socket electrodes will cause personal injury. When the plug is inserted, the protective door will be pushed open, so that the plug and socket electrodes will contact and get electricity. However, in the current five-hole combined socket, due to the close arrangement of the two-plug and three-plug positions, generally only one protective door is provided, that is to say, a protective door is used to cover the three-plug and two-plug electrodes at the same time. When moving, the three-plug and two-plug electrodes are exposed at the same time. Therefore, with this protection door structure, when only two or three plugs are used in the five-hole combined socket, the electrode of the unused socket is not covered by the protection door and is in an exposed state, which is easy to cause small metal damage due to children playing or careless. There is still a potential safety hazard if the object extends into the socket and touches the socket electrodes to cause personal injury.
