Terminal blocks are electrical connections that are used to establish connections between wires and other electrical components. They are predominantly used in the electrical industry, but have steadily grown in popularity in other industrial and commercial applications as well. Terminal blocks come in a variety of types and sizes, with each type serving a particular purpose. This article will focus on the 1990889 type and discuss the applications where it can be used, and the principles which it follows to achieve its purpose.

What is 1990889 Terminal Block?

The 1990889 terminal block is a type of connector used to connect two or more wires together. It is similar to other terminal blocks, but distinct in how it accomplishes the connection. The 1990889 terminal block has an insulated base with two plates that can accept a wide range of wire gauges, from AWG 30-14. The connection process involves inserting both ends of the wire into slots located on each plate. A spring-loaded lever is then pressed down and clamps the wire securely into place. The 1990889 terminal block also features a built-in test point that can be used to verify the connection has been made properly.

Applications

1990889 terminal blocks are prevalently used in the electrical industry due to its versatility. It is often used in applications where multiple wires need to be connected, such as in control systems. Furthermore, it is also used in a variety of high reliability applications such as automotive wiring, computer repair, and electrical power distribution.

The 1990889 terminal block also lends itself to other fields. In manufacturing, the terminal block is popularly used to interconnect the individual components of panel-based machines. Furthermore, in economic sectors such as telecommunications, the 1990889 terminal block is often used for installations which require up to 24 individual wires to be connected.

Working Principle

The 1990889 terminal block works on the principle of electrical contact, wherein a metal contact material is used to connect wires together. The metal contact material used in the 1990889 terminal block is a combination of copper and a proprietary nickel-plated alloy. This combination allows electricity to flow through the connection while providing protection from corrosion and other environmental damage.

The 1990889 terminal block also features the aforementioned spring-loaded lever. This lever helps to keep the connection secure by applying extra pressure on the wire when the lever is pressed. This ensures that the connection remains secure even when subjected to external forces. Additionally, the 1990889 terminal block features a test point which can be used to verify that the connection is secure and that power is flowing through the connection.

Conclusion

1990889 terminal blocks are used extensively in a variety of industries due to their versatility. They are often used in applications involving multiple wires, as the 1990889 terminal block can accommodate up to 24 wires. Furthermore, the unique combination of copper and proprietary nickel-plated alloy ensures a secure connection and protection from corrosion. Finally, the spring-loaded lever and test point help ensure the connection is secure and power is flowing through the connection.
