Terminal blocks, commonly called as “headers”, “plugs” and “sockets” are products that enable the connection between two wires or other two conductors of a connection. These products are used to link electrical circuits, especially used when a component is continuously producing and consuming electrical energy.

1982690000 Application Field

Terminal Blocks, headers, plugs and sockets are extensively used from small scale home appliances and computer motherboards to huge industrial uses. In a limit switch, a terminal block is used to connect the appropriate limit switch contacts. They are also used in other electronic items such as DVD players, alarm systems, cameras, and so on. These products are also necessary for the installation of lightning systems in churches, large offices, and other places.

Working Principle

The working principle of terminal block, headers, plugs and sockets revolves around the ways a wire conductor interacts with the product. A wire conductor is usually connected with clamps or screws. The wire in the terminal block passes through the wire thus connecting one conductor to another.

The clamp arrangement of screws or clamps holds the wire in place and thus the installation is complete. Once the power is switched on, the electricity flows from the source through the wires and reaches the targeted device accordingly.

Product Variation

Terminal blocks range from miniature products to huge blocks that handle thousands of volts of electricity. The size of these products can vary in length or thickness, and the size determines how powerful the electrical current it can transfer.

In industrial uses, block terminals are used to secure a conductor to a device. The conductor moves between two contacts, one called the ‘live’ and the other called the ‘neutral’. This type of terminal block contains an insulator, screws or clamps within, which can be tightened using a screwdriver or a spacer, depending on the model.

Terminal blocks, headers, plugs and sockets are available in various sizes, shapes and materials to suit the needs of different application fields. Some products are exclusively designed with a few meters wire while some others can handle several hundred meters of wire.
