Terminal Blocks - Headers, Plugs and Sockets is a comprehensive device used for secure connections of electrical and electronic components. Commonly used on breadboards, printed circuit boards and equipment panels, busbar systems and other industrial electrical connections, these devices are commonly known as ‘header pins’ or ‘plug pins’. The terminal blocks are designed to mechanically secure two or more conductors together and prevent any accidental disconnection or other electrical problems.

The most commonly used terminal blocks are the headers, plugs and sockets. Headers are usually installed near the beginning of an electronic system or directly on the printed circuit board. The header has two parts: a connector and the slot. Headers are used to electrically connect components with lower current requirements, such as LEDs, LCDs, resistors and transistors. They are usually provided in a grid-like configuration so that components can be securely fastened onto them.

Plugs are the second type of terminal blocks, and are the most common in electrical and electronic systems. The plug is inserted into a socket on the board, usually into one of several pre-drilled holes, and is secured with a nut or thumbscrew. Plugs also have two components, a housing and a pin, so that two or more wires can be connected together. Most plugs are provided in a modular configuration that allows multiple plugs to be stacked together with the pins in the same row or column. Plugs are used to connect components that require higher current, such as motors, power supplies and transistors.

The third type of terminal block is the socket, which is used to connect heavier components, such as transformers, power supplies and motors. The socket is a much larger version of the plug, and provides further strength and security to the connection. Sockets are usually provided in a single row or column configuration, and are usually drilled directly into the circuit board. The pins are securely fastened by screws or nuts to the panel, preventing any damage that may occur due to vibrations or accidental disconnection of the cables.

Terminal blocks - headers, plugs and sockets are essential in providing secure, reliable and safe connections for electrical and electronic components. They provide better protection against electrical hazard and reduce the chances of damage or short circuits due to incorrect wiring. The use of these devices is easy and provides a simple, yet effective way to ensure the quality and safety of electrical connections.
