The plug corresponding to the desk lamp socket is loose and not burnt out. Please analyze the reasons.

The plug corresponding to the desk lamp socket is loose and not burnt out, which is the aging of the copper sheet of the socket jack. According to relevant information, the quality of the socket itself is problematic. The copper sheet in the socket is relatively thin, aging and deformation will lead to the socket being loose and unstable, and the use process is too violent. Some people like to unplug the wire directly, instead of unplugging it, which will easily lead to loose sockets and damaged wires, which is very dangerous. If the socket is loose, it must be repaired in time to avoid fire.
