Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are an essential component for the organization and connection of wires in electrical and electronic circuits. The terminal blocks, also known as headers, plugs, and sockets, are designed to allow efficient, organized connections from multiple wires to one another. The terminal blocks provide both safety and convenience in the process of connecting the wires. This article takes a closer look at the application field and working principle of the 1986720-4 type of terminal blocks.

Application Field

The 1986720-4 type of terminal block, which is a Delphi Metri-Pack 150 series inline connector, is primarily employed in the automotive industry for making wire connections. The Metri-Pack 150 connectors generally come in two sizes, Metri-Pack 150.2 and Metri-Pack 150.4. The 1986720-4 connector is part of the Metri-Pack 150.4 category and is designed to accommodate up to 9 total contacts with a 12 AWG wire size.The Metri-Pack 150.2 and Metri-Pack 150.4 terminal blocks are used in a variety of applications in the automotive industry, including radiator fan connection, fuel pumps, climate control, and interior lighting applications. In some cases, the terminal blocks are used in other industries that require wire connections, such as agricultural equipment, industrial machinery, and instrument panel connections. The terminal blocks are also used in robotics, medical, and telecommunications applications.

Working Principle

The basic working principle of the 1986720-4 terminal block is a simple yet effective process. The wires are connected to the terminal block by inserting the female end of the wire into the terminal’s female connection and subsequently soldering the connections. The wires are then secured in place by tightening the terminal’s screw. If the screws aren’t tightened securely, it may resulting in an improper connection and/or a short circuit.The 1986720-4 terminal block is designed for ease of maintenance and also features snap-in mounting posts that allow for quick replacement of the blocks. The robust steel construction also contributes to its lasting durability. The blocks are also designed to prevent vibrations and environmental factors from damaging the connection. The terminal blocks are temperature rated for -40°C to 125°C in some configurations.

Conclusion

The 1986720-4 terminal block is used in a variety of automotive and other industrial applications where secure wire connections are required. The terminal block is easy to install, and features snap-in mounting posts and a robust steel construction for protection from vibration, moisture, and repelling dust. The terminal block has a temperature rating of -40°C to 125°C and provides a reliable connection for the electrical circuits.
