What is a terminal block?

A terminal block, which is also referred to as a terminal connector or screw terminal, is an electrical gadget used for joining two or more wires securely and conveniently. Normally it has a base made of either plastic or metal and some screws or metallic terminals. The connection between the wire and the terminal is made by removing insulation from the end of the wire, wrapping it around the terminal or inserting it under a screw. These blocks are applied in different electric works ranging from domestic wiring systems to control circuits of industries.

The main benefit achieved while using these blocks is that they enable secure connection points for many wires. Hence this helps in minimizing chances of having loose contacts which might result into short circuiting thus damaging equipments or causing accidents like fires due to electricity leakage. Also ease in maintenance and trouble shooting since individual wire can be disconnected then reconnected without disturbing other parts of a circuit.

There are various kinds of these gadgets created according to their applications as well as sizes suitable for specific wires.Barrier type features divisions between each adjacent terminal hence preventing any accidental contact while feed through enables passage without connecting.PCB refers those mounted on printed circuit boards whereas modular can easily snap together thus creating customized configurations but all serve one purpose.Terminate reliably safe electrical connections under different settings.
