Barrier blocks, also known as terminal junctions or junction blocks, are a kind of connective device used in control and automation. They offer protection to control circuits from hazardous voltages, currents, and extreme temperatures. CB20210907 is a type of barrier block which can be used for a variety of applications, including automotive and industrial. In this article, we will explain the application field and working principle of the CB20210907 terminal block.

Application Field

The CB20210907 terminal block is suitable for a wide range of applications, such as automotive, industrial, and residential. In the automotive industry, it is used to connect the engine electronics with the wiring harness. In the industrial sector, it is used to connect motors, relays, and other components. In residential applications, it is used for connecting electrical appliances to power supplies. Regardless of the application, the CB20210907 terminal block provides the necessary current and voltage protection to ensure the safety of the system.

Working Principle

A CB20210907 terminal block is composed of two pieces of brass; one is a copper-plated sleeve and the other is the main body. The sleeve is connected to the main body by inserting two pins into the corresponding holes. Two small spring-loaded screws are used to pressure the pins. This ensures that the pins are firmly locked in place and provide the necessary current and voltage protection.

When the pins are inserted, the sleeve is pushed against the main body, forming an electrical connection between them. The current flows through the sleeve and the main body, providing the necessary protection. The contact between the sleeve and the main body can be maintained even when vibrations occur, ensuring the reliable operation of the circuit.

Conclusion

The CB20210907 terminal block is a versatile connective device suitable for a variety of applications, including automotive, industrial, and residential. Its two-piece design composed of a copper-plated sleeve connected to the main body through two pins provides reliable current and voltage protection. The pins and spring-loaded screws ensure that the pins are firmly locked in place and the contact between the two pieces is maintained even when vibrations occur, making the CB20210907 terminal block a reliable solution for electrical systems.
