I am repairing a cordless kettle's base plate whose the power cord was cut. The new wires need to be connected to the contact pins in the base. Originally, quick disconnect terminals were used with two crimped sections, one on the wires and another on the insulation, all covered with heat shrink.
Is there any safety concern with soldering wires directly instead of using crimp terminals?
I don't have the same type of quick disconnect terminals or the required crimp tool. The options I can think of are:
- Buy general purpose quick disconnect terminals which can be crimped with a regular crimp tool. The insulation is probably not rated for 105C like the power cord, though I don't think the base of the kettle should be reaching such temperatures.
Try to reuse the old quick disconnect terminals by uncrimping the wires and then soldering the new wires into the terminals, and using heat shrink over the whole thing to approximate the original assembly.
Solder the new wires directly onto the terminals and cover with heat shrink.
The power cord is 16 AWG and rated for 105C and 300V.
Option 3 would be the easiest for me and require no new purchases. Option 2 would take the most effort and time, but require no shopping trip. Option 1 would look the best, but I don't know if the insulation used is suitable in this case. I would think it should be passable, but... what are your thoughts?
