2-1546965-4 Terminal Blocks - Barrier Blocks Application Field and Working Principle

Terminal Blocks - Barrier Blocks are very common electrical wiring systems used in power and communications systems. They are also referred to as barrier strips and splice blocks. This type of wiring system typically consists of a molded hard plastic case that contains metal or plastic barriers, allowing connections between wires. What makes Terminal Blocks - Barrier Blocks particularly useful is that they provide a secure way of connecting multiple wires quickly and easily.

Application Field

Terminal Blocks - Barrier Blocks is a popular choice for many industries, from the automotive industry to the aerospace and defense sectors. They are also common in communications equipment and in power systems for both commercial and industrial applications. In addition to electrical connections, Terminal Blocks - Barrier Blocks can also be used for data connections, such as Ethernet and other forms of wired connections. In the automotive field, barrier blocks are used to provide power to a variety of systems including navigation, entertainment, and air conditioning. They are also used in communication systems in vehicles and on military aircraft. The aerospace industry specifically utilizes Terminal Blocks - Barrier Blocks to provide connections between wire bundles.

Working Principle

Terminal Blocks - Barrier Blocks are based on electrical principles and have a relatively simple design. The shell is typically made of molded plastic, with multiple pins arranged in a line. Each pin is divided by a barrier, with each section accommodating a different type of wire. For example, one section may accept only 12AWG wire, while the other may accept 14AWG wire. The wires are inserted into the appropriate openings in the block and are secured with a setscrew. The setscrew holds the wires in place, and prevents them from being pulled loose or moved. The barriers in Terminal Blocks - Barrier Blocks prevent any electrical current from crossing over from one wire to another. This prevents electrical shorts, which can cause expensive electrical damage. In addition, most Terminal Blocks - Barrier Blocks are polarized, meaning that the pins inside the block are arranged in a specific way, so that they will only allow one type of wire to be inserted in a certain direction. This ensures that the connections are made in the correct order, avoiding further potential problems.Terminal Blocks - Barrier Blocks contain pins that are typically marked with numbers, so that it is easy to connect wires with the same numbers together. This simplifies the wiring process, and makes it easier to replace or rearrange components in case of an issue.

Conclusion

Terminal Blocks - Barrier Blocks are an excellent choice for many industrial and commercial applications. They provide secure, simple, and reliable electrical connections, and are ideal for both power and data applications. By having a good understanding of the application and working principles of Terminal Blocks - Barrier Blocks, you can be assured that your connections are secure and reliable.
