Description:
How do we connect two wires? By stripping the insulation at the ends and twisting them together? Yes, it works. But, is it safe? We can apply insulation tape over the joint or use a wire connector. But what if there are a number wires that need to be joint/connected near each other? Or, what if multiple outgoing wires are to be connected to a single incoming wire? Then this method will neither be safe nor be convenient anymore. Here we use terminal blocks.
Screw type terminal block can be welded directly on the PCB.
Why you need a terminal block?
• Screw terminals are low in cost when compared to other types of connectors
• It can be readily designed into products for circuits carrying currents of from a fraction of an ampere up to several hundred amperes at low to moderate frequencies.
• The terminals easily can be re-used in the field, allowing for the replacement of wires or equipment, generally with standard hand tools.
• Screw terminals usually avoid the requirement for a specialized mating connector to be applied to the ends of wires.
Applications:
terminal block combination commonly used for microphone- and line level-audio signals, and for control signals.

If you think that the terminal block is causing any problem in your appliance, you can follow the steps below to test:
1. Take precaution: Turn off the power source by putting the control panel switch at OFF position. Unplug the power cord of your appliance from the wall outlet (if there is any).
2. Find terminal block: Remove the cover of the appliance where the power cord enters the appliance. Follow the power cord, you will find the terminal box at the end.
3. Test terminal block visually: Check carefully if there are any cracks or corroded wires. Also check for burned or loose wires. If you see any of these problems, replace the terminal block.
4. Disconnect terminal block: With the power source turned off, remove the mounting screws for the terminal block. Label the wires with masking tapes indicating the terminals they connect to. Pull off the wire connectors after unscrewing them. Disconnect the ground wire from the block. Disconnect the terminal block by pulling.
