Terminal Blocks - Barrier BlocksTerminal blocks are a type of electrical device used to connect electrical wires or components together. Also known as barrier blocks, they are mainly used to secure wires in place, protect wires from damage and reduce the risk of electric shock and short circuits.Terminal blocks are available in different models and sizes, the most common being a dual row pin type. Other types include drum, skateboard, fuse, ISO and IDC, and square post. Barrier blocks are usually available in plastic or metal housings.0387291357 application field and working principleBarrier blocks are a type of electrical terminal blocks which can be used in a wide variety of applications, such as machine control systems, audio-video, motor control, process control and telecommunications.The working principle of barrier blocks is based on electrical contact pressure, which is applied to the contact surfaces of the wires or components to be connected. This contact pressure ensures the electrical connection between the wire or component and the barrier block. The pressure results from the tightening of the screws which hold the wires or components in place. The screws must be tightened to the correct torque, in order to ensure good contact between the wire or component and the barrier block.The contacts of barrier blocks are devised in such a way that they can be used for different types of wires or components. For example, the contact system of the pins can accept stranded wire of different sizes. The contact system can also be adjusted depending on the components being used. The contacts can also feature different colors to easily identify the different circuits.In addition to providing an electrical connection, barrier blocks are also designed to protect the wires or components from corrosion or over-voltage. The contact pressure, as well as the mechanical tension of the screws, create an insulation which prevents corrosion. Some models include surge limiters for over-voltage protection.In conclusion, barrier blocks are a type of electrical terminal blocks which can be used for a variety of applications. They use electrical contact pressure to ensure a secure connection to wires or components, and are also designed to protect them from corrosion and over-voltage.
