This socket is always in poor contact. How can I open it?

Generally, the fixing screws can't be seen outside the 1 wall socket. Only when the socket cover is opened can the screws be seen. There are one or two small openings on the side of the cover plate, which need to be pried open slowly with a flat screwdriver.

After opening the lid, you will find that there is a screw on the left and right of the wall switch, which needs to be unscrewed with a screwdriver.

After unscrewing the screw, don't take out the wire with a screwdriver in a hurry. First measure whether the wire is charged with an electric pen, and then unscrew the terminal after confirming that it is not charged.

When replacing a new socket, the normal wiring mode is that the left side is the zero line, the right side is the live line, and the upper side is the ground line, which is often called "left zero and right fire". The zero line is generally blue, the fire line is generally red, and the underground line is generally yellow and green. We just need to connect it according to the wiring method before disassembly.
