It looks like the wire was lose during operation and heated up the connector until it started burning. It is not the 120 degrees that cause this but the loose connection. I also see that the connection to relay is badly soldered so you would need to solder that one as well. I am afraid that you have to replace the connector. If you can't find a new connection you could solder the wires directly to the contacts at the bottom.
A lose connection can easily heat up like that. The heated bed does take quite some current and if there is a weak contact it will burn.
