1932042-1

Backplane connectors provide a way to connect a number of PC boards and other electrical components together, creating a system-level interconnect. The 19320421 is one type of backplane connector, characterized by its specialized design and unique capabilities. Here, we look at the application fields and working principle of the 19320421 backplane connector.

Applications

The 19320421 backplane connector is designed for applications where power, speed and signal integrity are of utmost importance. It is well suited for digital product designs, particularly when interfacing with multiple Short Voltage PCBs (SVT PCBs). The 193204 is capable of very high speed data transmission, up to 5 Gbit/s. As such, it is well suited for a variety of IT and telecoms applications, such as set top boxes, routers, switches and gigabit ethernet hubs.

The 19320421 backplane connector is also well suited for high speed data transmission and networking involving different types of media, such as optical fibre. This is a common requirement in high bandwidth applications, such as cable television and internet TV services.

Working Principle

The 19320421 backplane connector utilizes active contact technology, which eliminates high impedance bounce (HIB) and EMI. It works by providing a 3-phase contact mechanism between the motherboard and the SVP board. Each phase includes an array of pins, made of gold plated over nickel. The pins are surrounded by a plastic spacer. As the board and the connector are brought together, the pins penetrate the spacer to make contact.

The pins are spring loaded, ensuring very tight contact for high reliability and decreased contact resistance. The pin and spacer assemblies are also designed to keep the pins and spacer parallel to each other for maximum contact force and performance. The three-phase system also cancels contact noise to maintain signal integrity.

Conclusion

The 19320421 backplane connector is an ideal solution for high speed data transmission and networking applications. Its specialized design and active contact technology make it an excellent choice for applications where speed, power and reliability are of the utmost importance.
