Terminal Blocks - Barrier Blocks

Today, most electronics systems use terminal blocks to interconnect the system’s different printed circuit boards and components. If the system requires large currents or high voltage, there is a need to ensure that the connection is safe and secure. The use of barrier blocks for terminal blocks in this situation provides a secure, reliable and safe interconnection.A barrier block is essentially a combination of a terminal block and a metal barrier that separates each terminal on the block. The barriers provide an extra layer of isolation, so that even if the wires at the terminal block come loose, the overall system remains safe and secure. The most common type of terminal blocks are the dual wire entry barrier blocks. These barrier blocks handle up to two wires per terminal. The two wires enter the barrier block from opposite sides, which increases the safety and security of the connection. They are available in a wide variety of sizes, from the smallest 2-pin blocks to larger units that contain up to 96 pins. Some barrier blocks have a removable jumper that can be used to further enhance the isolation of the connection.The uses of barrier blocks date back to around 2013-3/4, and they have become quite popular in recent years. They are commonly used in commercial, industrial and military applications, and they are used to connect high-power devices, such as motors, lasers, transformers and high-voltage systems.The working principle of barrier blocks is quite simple. The terminals are connected together via silver-plated copper contacts, which provide a good electrical connection. The terminals are held together with screws, nuts or clips, which creates a strong connection and prevents the terminals from coming loose.The barriers are made of a metal that is non-conductive, such as zinc or plastic. The barriers provide an extra layer of safety, which prevents the wires from coming in contact with each other and causing a short. The barriers also protect the terminals from dust and debris, which can cause corrosion and lead to an electrical fault.As mentioned earlier, barrier blocks are available in a range of sizes and configurations. Many barrier blocks have a "tie-point" design, which means the terminals are arranged in rows and have a hole in the center that can be used to secure the wires. This design allows for a secure connection and protects the wires from coming loose.In summary, barrier blocks offer a secure, reliable and safe means of interconnecting printed circuit boards and components. They are available in a wide range of sizes and configurations, and they provide an extra layer of safety and protection for the connections. The use of barrier blocks in high-powered electronic systems has become increasingly popular in recent years.
