Terminal Blocks - Wire to Board

Terminal Blocks are the building blocks of almost any electrical circuit. They are used to house multiple wires within one convenient point so that their connections are secured and their electrical energy is safe from outside interference. Terminal blocks are useful for both low-level circuit applications and high-power, work station-level systems. This article will focus on the terminal blocks that fall into the “wire to board” category and specifically examine the application fields and working principles of the 1990957 series.

Application Fields

The 1990957 series of terminal blocks from Automated Distribution Systems are designed for extreme-use environments. Their patented features make them ideal for connecting heavy equipment, vehicles, and electrical installations where durability, reliability, and longevity count. The terminal blocks have various connection options and are compatible with existing systems and fixtures. Their innovative design allows them to fit into any application, regardless of its size or shape.

Working Principle

Terminal blocks work by creating a secure electrical connection between two wires or components in an electrical circuit. The outer casing of the terminal block houses the various wires, while the two pins inserted on the inside of the block create the electrical connection. The two pins are made from hard chrome-plated steel, providing maximum corrosion resistance. When power is supplied, current flows through the two pins, allowing it to travel between the two connected wires.

Advantages and Disadvantages

The 1990957 series of terminal blocks offers several advantages over traditional wire-to-board connectors. They are extremely durable, making them ideal for extreme-use applications. Additionally, they are designed for maximum performance, ensuring they can handle high current ratings. Finally, their innovative design makes them compatible with existing systems, allowing for easy installation and easy maintenance. One of the disadvantages of terminal blocks is their potential for human error. Incorrectly wiring a terminal block can cause an electrical fault, leading to the shorting or overloading of components in the electrical circuit. Additionally, installing the wrong type of terminal block can lead to overheating or arcing, both of which can be potentially dangerous.

Conclusion

The 1990957 series of terminal blocks are designed for extreme-use applications where durability, reliability, and performance count. Their patented features make them ideal for connecting heavy equipment, vehicles, and electrical installations. The two pins inside the block provide the secure electrical connection that is needed in the circuit, while the outer casing houses the various wires and cables. While terminal blocks may have the potential for human error, they also offer the advantages of easy installation, compatibility with existing systems, and longevity.
