Terminal Blocks - Headers, Plugs and Sockets 1756573 Application Field and Working Principle
Terminal blocks are devices that are used to create electrical connections between two or more circuits by allowing physical connection of live and neutral wires in a system. They are found in applications including LED lighting systems, industrial automation systems, and HVAC systems. Terminal blocks come in a wide range of sizes and configurations, with several types of terminal plugs, headers, and sockets available on the market. These can be broken down into different categories depending on the application field and working principle. Types of Terminal Blocks
One of the most common types of terminal blocks are jumper blocks. They are used for linking electrical circuits, making the connection between two wires without a need for soldering or further wiring. Jumper blocks come in a variety of shapes and sizes, featuring mid- and high-voltage ratings with a choice of mounting options and functions.Another type of terminal block is the feed-through terminal blocks. These are typically used in high-power applications, and are designed to combine large wires into a single connection. The device offers better insulation and distortion than other types of terminal blocks. The feed-through terminal blocks are made of insulating plastic and feature multiple screws for connection and wiring, designed to route several large wires through a single terminal block.The last type of terminal block is the terminal strip. These are single-wire devices typically used in low-voltage circuits, and are ideal for applications where only one wire needs to be connected. The terminal strips are made of metal and feature two screws for connection and wiring. Working Principles of Terminal Blocks
When power is supplied to a terminal block, the circuit completes and an electrical connection is established. In jumper blocks and feed-through terminal blocks, the electric current passes from one wire to another through the terminal. The terminal blocks can be disconnected by manually turning the screws clockwise, which will release the respective wires. In the case of the terminal strip, the electric current simply passes through the metal strip and the contact point to complete the circuit.Terminal blocks are designed with safety in mind, and feature protection against overcurrent, overvoltage, and short circuits. This ensures that the system will remain in operation while fulfilling the desired electrical requirements. Conclusion
Terminal blocks are an essential part of any electronic or electrical system. By understanding the different types of terminal blocks, and the principles of their operation, it is possible to choose the right type of device for a given application. In addition to safety and efficiency, terminal blocks offer convenience by reducing the need for wiring and soldering. The application field and working principles discussed above will help to make the selection of the right type of terminal blocks easier.
