0395232923 Application Field and Working Principle

Terminal blocks, also known as headers, plugs and sockets, are electrical devices used to terminate and electrically connect two wires or a multi-wire cable. Used in residential and commercial buildings, they provide a simple and efficient way to manage large amounts of power within a single system. They are often found in industrial settings, as well.

The type of terminal block typically used depends on the application and desired results, as there are many variations of the device. The most basic of these include the standard terminal block, the multipoint terminal block, the shrouded terminal block, the header terminal block, and the flexible terminal block.

Standard Terminal Blocks

Standard terminal blocks are the most common type of terminal block used today. They provide easy electrical connection between two or more wires or cables, and are usually found in residential and commercial buildings. Standard terminal blocks have two metal pins, each with a hole for the wire to be inserted. The pins are connected by a metal strip, which allows the current to pass from one pin to the other.

Multipoint Terminal Blocks

Multipoint terminal blocks are designed to allow for multiple connections of wires or cables. They are usually used when more than one source of power needs to be connected, such as in a circuit where a number of power sources need to be connected to one central point. Multipoint terminal blocks typically have multiple holes for multiple wire inputs.

Shrouded Terminal Blocks

Shrouded terminal blocks are designed for use in hazardous or wet locations. The metal shroud around the pins prevents the contact between the metals and the insulation, providing increased safety and preventing accidental contact. The shroud also prevents wires or cables from disconnecting from the terminals.

Header Terminal Blocks

Header terminal blocks are designed to provide electrical connection with board-mounted connectors. Header terminal blocks are usually soldered onto a PCB, providing an electrical connection between two or more wires and a board. Header terminal blocks are commonly used in industrial settings, such as in machinery, medical instruments, and electrical equipment.

Flexible Terminal Blocks

Flexible terminal blocks provide a simple and easy way to manage power connections in residential and commercial buildings. These terminal blocks are designed to be flexible, allowing them to be used in tight spaces or unusual configurations. Flexible terminal blocks are usually made of plastic or rubber, allowing them to be bent into various configurations.

Conclusion

Terminal blocks, also known as headers, plugs and sockets, are a versatile device used in a variety of applications. They provide a simple and efficient way to manage large amounts of power within a single system, making them an invaluable tool to anyone who works with electricity. Different types of terminal blocks are available, depending on the application and desired results.
