Backplane connectors are specialized connectors used to interconnect devices that are part of a backplane, such as a mother board or daughter board. The 205156-1 backplane connector is one such specialized connector that can be used for this purpose. This article introduces the application field and working principle of this connector.

Application Field

The 205156-1 backplane connector is a type of rectangular connector designed for printed circuit board assemblies. The two-piece connector consists of two parts, the header and the receptacle. It provides high connection density for high-speed signals, making it perfect for applications requiring a pluggable connection. It can also be used in a variety of markets, from telecommunications to medical equipment. It is also suitable for a range of systems, including those requiring a rugged environment.

The 205156-1 can be used in a variety of applications such as telecomms, datacoms, broadcasting, industrial, medical, aviation, military and consumer electronics to name a few. Its applications can be further divided into applications requiring extra contacts such as USB 2.0/3.0, which require two additional contacts for a high-speed signal, as well as applications requiring more power contacts such as SATA power. It is also designed for use with high-speed differential pairs for 10GBase-T applications, which require four differential pairs for a total of eight signals.

Working Principle

The 205156-1 backplane connector is designed to have two unpluggable parts— the header and the receptacle. The header has 30 pins and the receptacle has 32 contacts. The pins on the header are designed to fit into the sockets of the receptacle, allowing for a secure connection. The contacts on the receptacle also feature a pressure-fit connection for easy installation. The 205156-1 is designed to make a secure connection between the two parts, providing a reliable link for data transmission.

The 205156-1 connects both parts by soldering the contacts on the receptacle. This solder joint provides a secure connection between the header and the receptacle. It is important to ensure that the solder joint is made with high quality, to promote a reliable connection. The contacts on the receptacle are designed to be spring-loaded, meaning that they will hold the header tightly in place, which helps reduce the chance of signal loss.

The 205156-1 is also designed to be resistant to shock and vibration. Its strong construction ensures that it can stand up to frequent use in various environments. It also features a low profile design, which is ideal for applications requiring a smaller form factor. Furthermore, the connector has a high temperature rating, which makes it suitable for use in extreme conditions.

Conclusion

The 205156-1 backplane connector is a specialized connector designed for connecting devices such as a mother board or daughter board. It provides high connection density for high-speed signals, making it ideal for applications in a wide variety of markets. Its two-piece design features a header and a receptacle, which are soldered together to make a secure connection. The connector is also designed to be resistant to shock and vibration, making it suitable for use in rugged conditions. All of these features make the 205156-1 an ideal choice for a wide variety of applications.
