Terminal Blocks - SpecializedTerminal blocks are specialized connections and wiring tools used in electric and electronic circuitry. As the name suggests, they are wired to form a block, thus forming a special connection and wiring system for electric and electronic components. The terminal block technology has been integrated in many modern, everyday electronic devices like TVs, PCs, mobile phones and appliances.Utilizing terminal blocks has great potential as they offer various advantages like conduction reliability, durability, easy assembly, and the ability to connect devices with differen wirirng schemes. Terminal blocks also have distinct application fields and working principles.Application of Terminal BlocksTerminal blocks are widely used in electronic circuits for multiple purposes. Being a great way to bundle electrical conductors and/or wires, they are preferred in industrial settings. Industrial control systems require the use of high voltage cable to pass power from the main panels to a number of loads. Specialized terminal blocks are designed to cope with very high voltages.Terminal blocks are also often used in computer and HVAC systems. They are usually used to hold high performance temperature and speed control systems, and in data acquisition systems where data from multiple sources is being collected.Terminal blocks can also have a role in providing electrical connections in an autonomous system. The use of terminal blocks in an autonomous system is essential as it enables using variety of wiring schemes which can be connected to each other. In that way it is possible to build a large control network with various power sources.Finally, switching boards, motors and other electronic components in production and industry are usually wired with terminals blocks. This is very useful, as manual wiring scheme can be implemented using terminals blocks, which is a much simpler and faster process than manual wiring. Working Principle of Terminal BlocksThe main components of a terminal block are block body, terminal pins and a locking screw with a terminal head. The body contains several terminal pin slots, and the locking screw is used to hold the metal pins into the block body. This determines the electrical connection between the pins and block body.The pins can be wired with a wire-ended cell of the proper type, which can be secured by the locking screw. This creates the electrical connection from the pin to the wire-ended cell. The wire-end cell then electrically connects the wire to the terminal pins. The terminal pins can also be used for connecting other types of wiring components used by industrial and other applications. For example, some pins have a connection plate for connecting the wire to other wiring components like sockets, jacks, and switches.ConclusionTerminal blocks are a great way to provide reliable electrical connections and wiring for electric circuits. They offer many advantages and have multiple application fields and working principles, making them very versatile. Terminal blocks can be used in industrial settings, computers and HVAC systems, autonomous systems, switching boards and other electronic components. Their working principle is based on connecting the pins to a wire-ended cell and using the locking screw to hold the pins into the block body, thus creating the electrical connection from the pin to the wire-ended cell. Terminal blocks are great solutions for simplifying and speeding up the wiring process and providing reliable electrical connection.
