Rectangular Connectors - Housings

The 172157-2 application field and working principle is an important element of modern consumer and industrial electronics. It is a type of rectangular connector housing, or housing with rectangular screws, found in many common products such as audio/video, automotive, security, computers, communications, power supplies, and control systems. It is designed to provide a secure connection for high power and/or high signal levels.

Design Overview

The 172157-2 rectangular housing is a single, 2-part design with a locking system. It has a top and bottom and is designed for direct-mounting on the PCB board. The housing includes two rectangular screws for secure terminal retention and provide a snug fit. The housing has four internal bosses that provide multiple means of securing the connector by utilizing various screwtypes. The housing is also designed with double contact points for increased reliability.

Benefits

The main benefit of the 172157-2 rectangular housing is its tight fit and secure connection. Due to its construction, it is more suitable for higher power and/or high signal applications. The housing also reduces electromagnetic and radio frequency interference, as well as electrical noise, and has improved environmental performance. It is also advantageous because it can easily be replaced or integrated into existing systems.

Application Fields and Working Principle

The 172157-2 rectangular housing is commonly used in consumer, industrial, and avionic applications. It is typically found in audio/video, automotive, medical, aerospace, and power supply applications. It is ideal for devices such as radio transceivers, air conditioning controls, projection systems, electric meters, and even electric heaters.

The working principle of the 172157-2 rectangular housing is quite simple. Upon connecting the housing to the PCB, the rectangular screws are tightened securely to the PCB. This tightens the connection between the two components and ensures an electrical connection is made. Once the connection is made, the signals are conducted through the PCB. This type of connection is often used for higher power and/or high signal applications, as it creates a stronger connection than other types of connections.

Conclusion

The 172157-2 rectangular housing is an important component in many modern electronics. It creates a strong and secure connection for high power and/or high signal applications. It can easily be integrated into existing systems, and due to its design, it reduces electromagnetic and radio frequency interference, as well as electrical noise. As such, it is ideal for consumer, industrial, and avionic applications such as radio transceivers, air conditioning controls, projection systems, electric meters, and more.
