Replacement for terminal block for bed heater

[Perchik 2]

My bed stopped heating recently and I traced the problem to the terminal block on the main board. One side of this block was burned out. If I remove the wire and touch it directly to the contact on the board, the bed heater starts working again.

 

Can I just solder these wires to the bed, or do I need to put in a new terminal block? If so, does anyone have an idea of what part to order?

 

I'm competent at soldering but lack some of the knowledge of *why* things are the way they are. Does the terminal block just provide an easier way to replace the wires, or does it offer some other protection in addition?

 

Also, any idea why the old terminal block burned out? It was yellowed and had a small burn spot on it...

Big bed= high current,   Hence it burning out.  It probably pulls 10 amps when running.  Might not have been tight enough, or worked loose from thermal cycling.   It’s common to periodically shut down and relighten all connectors on industrial machinery plants 

 

you can use any connector that works at the local electrical store, or just solder on directly.   Just make sure you have good contact, a large well soldered joint will be perfect
