Cut off the burnt terminal with scissors or diagonal pliers and connect a new terminal. There are two types of electric heating tube links with 0.5mm thickness and 0.8mm thickness, so if you are uncertain, you can buy 0.5 terminals directly. If you can't buy a terminal, mind cutting the terminal, connect the wire directly to the insert, remember, wrap it tightly, and then solder it with an electric soldering iron.
