Backplane connectors provide electrical connection between the printed circuit boards (PCBs) of a system. They typically consist of two mating rectangular metal frames that are linked together, each containing a set of contacts that latch into one another when the connectors are mated, ensuring secure electrical connection. Specialized backplane connectors such as 6766440-1 are designed to meet specific application requirements. This article outlines the application fields and working principle of 6766440-1.

Application Fields of 6766440-1

As a specialized backplane connector, 6766440-1 is typically used to provide a secure electrical connection in systems that must operate at higher frequencies, such as next-generation optical compacting systems and base station routers. It is also applicable in rugged system designs, particularly in aerospace, defense, and industrial applications.

Working Principle of 6766440-1

The 6766440-1 backplane connector has two mating frames. One frame consists of a set of 26 contacts arranged in two rows, each with 13 contacts. The other frame contains an array of 256 precision-formed coverage springs. As the mating frames are connected, each contact latches into the corresponding coverage spring, providing secure electrical connection at each contact.

The latching forces of the contacts are perfectly matched to the coverage springs, ensuring reliable operation under harsh vibration, shock, and temperature conditions. The contact force also reduces short circuit current levels in the event of partial contact or high current levels.

In addition, the 6766440-1 uses a patented impulse delay function to minimize signal line reflection. This minimizes bit rate errors and crosstalk between adjacent signal paths, allowing the connector to operate at higher frequencies and providing noise immunity in applications such as the next-generation optical compacting systems.

Conclusion

The 6766440-1 is a specialized backplane connector designed for high-frequency applications. It uses a uniquely structured array of contacts and coverage springs that ensure secure electrical connection under harsh environmental conditions. In addition, its patented impulse delay function allows it to operate reliably at higher frequencies.
