Terminal Blocks - Barrier Blocks

Barrier terminal blocks provide a convenient and easy way to permanently connect electrical components in circuits. They make potential high-impedance and low-frequency connections which allow components to be added, re-arranged, or replaced without needing to disconnect the wire that\'s connected to it. Barrier terminal blocks, also known as 0391001012, are also available in a variety of designs, ranging from miniature blocks to blocks designed for high-current and heavy-duty applications.

Barrier terminal blocks can be used to easily make transverse connections—connections that cross over one another without the need of making individual wires. This makes the installation process simpler and helps to create organized block designs in circuits. They provide a reliable and robust connection solution which is safe to touch and easy to install.

Components & Design

A 0391001012 barrier block consists of a main pinned block and one or more auxiliary blocks. It comes with two screws and two nuts. The screws act as retention screws for the auxiliary blocks which hold them into place. The connection can then be made by attaching the wires or components to the pins which pass through both of the blocks. The nuts then provide an additional securing measure for the screws and the blocks.

These pins have stamped-wire ends which enable them to securely clamp the wire in place. This ensures a good electrical contact between the two components, and they come in different material types such as brass and stainless steel. The outer part of the block is made up of a robust plastic material which provides insulation between the contacts and helps to protect them against oxidation and environmental influences.

Applications & Working Principle

The 0391001012 blocks are mainly used for high-impedance and low-frequency connections but they can also be used for medium-impedance applications. They are mostly used in industrial and commercial applications in which long-term reliability and robustness are essential. They are ideal for any application requiring connections with a lot of wires or components in a convenient and space-saving manner. These applications include control systems, electronics, telecommunications, power supplies, medical equipment, etc.

The working principle of this type of terminal block is fairly simple. It consists of two pins that are run through two blocks. The wire or component is then attached to the pin and the nut is tightened to secure the connection. The connection is further secured by the use of the retention screws that exert force on the blocks. This ensures a reliable and robust connection between the component and the terminal block.

Advantages of Using Barrier Blocks

There are numerous benefits associated with using barrier terminal blocks and these include:

• High-impedance connections that are reliable and robust.
• Simple and easy to install and use.
• Compact size that saves space.
• High degree of insulation ensures that the connected components remain safe.
• Easy to add, re-arrange, or replace connections without disrupting other connected components.

Barrier terminal blocks are a popular and reliable choice for large and complex applications where organized, multi-point connections are needed without having to use multiple individual wires. They are also suitable for many other types of projects and applications where a high-impedance and low-frequency connection is required.

Conclusion

The 0391001012 barrier terminal blocks provide a reliable and robust solution for making transverse connections in circuits. They are made up of a two-pin system that is secured by two screws and two nuts and their high degree of insulation ensures that the connected components are kept safe. These blocks are used extensively in industrial and commercial applications and provide an easy way to add, re-arrange, or replace connections without needing to disconnect the wire that is already connected to it.
