Terminal Blocks - Barrier Blocks Terminal blocks are designed to connect individual wires together in a circuit. They are commonly known as “breadboard blocks” because they look similar to the popular children’s toy. The most common type of terminal blocks are Barrier Blocks, which are largely used in electrical and electronics engineering. A20130803 barrier blocks are composed of two metal parts: the terminal block base and the conductive element known as a barrier blade. The base holds the blade in place and is securely mounted on a circuit board. The blade is typically made of copper and is designed to ensure electrical connections between wire terminals. Barrier blocks are commonly used to join electrical wires with high voltage or current ratings, as well as in low voltage and low current wiring applications. When two or more wires are connected with a barrier block, the contact force required to make the two wires touch is increased, improving the electrical connection and helping to reduce the risk of sparks or other forms of electrical arcing. In addition, the use of barrier blocks helps to prevent electrostatic discharge (ESD) and provides a secure electrical connection between components. In terms of function, barrier blocks have two main purposes. Firstly, they are used to bridge the gap between two wires, allowing them to be connected without the need for soldering. Secondly, they act as temporary breakers to disconnect two wires from each other. In many applications, barrier blocks are used in combination with wire terminal lugs, which helps to ensure proper electrical connections and extends the life of the connection. Terminal lugs are available in various sizes and shapes, and are designed to be attached to the terminal block. In terms of the wiring involved with barrier blocks, the wires are typically connected to the rear of the terminal block base. The rear of the terminal block base has specific holes for the wires to be inserted into. Once the wire is in the hole, a screw or nut is used to tighten the connection and ensure an electrical contact is made. In addition to their use in connecting individual wires, barrier blocks are also commonly used for connecting larger cables and bundles of wires together. These larger blocks are usually mounted on a panel or sheet metal wall for easy connection and access. Barrier blocks are designed to be used in a wide variety of applications. They can be used in both low voltage and high voltage applications, such as circuits connected to AC mains power and DC power supplies. They are also commonly used in industrial control systems, home automation systems, telecommunication systems and other applications where a secure connection between two electrical components is desired. In terms of safety, barrier blocks are designed to reduce the risk of electrical shock or electrocution. They are designed to be highly resistant to arcing, which helps to minimize the risks associated with exposure to high voltage. Furthermore, they are designed to be durable and reliable, making them a great choice for long-term installations. In conclusion, barrier blocks are a reliable and versatile electrical solution for many applications. They are designed with safety in mind, and are capable of providing a secure connection between two electrical components. Their use as temporary breakers also allows for quick access to components when needed.
