Backplane connectors are electrical components used to connect two or more printed circuit boards. ARINC (Aeronautical Radio, Inc.) has been a major manufacturer of backplane connectors for nearly seventy years, and the 1-445666-1 is a type of connector manufactured by ARINC. In this article, we will look at the 1-445666-1 application field and working principle.

Applications

The 1-445666-1 is a high-speed backplane connector ideal for a range of applications. It was designed for applications where high bandwidth is needed, such as in communications, servers, storage systems, industrial automation, instrumentation, and aerospace. The connector is commonly used for backplanes with edge contact requirements where high density and low cost is required, and its robust design allows it to be used for military and avionic applications, demanding high shock and vibration.

Design

The 1-445666-1 is a type of circular signal connector. It has a 45-pin configuration for a backplane size of 128mm square, and includes three separate 48-pin PCB connectors, offset by 7.5mm from the center. It is designed to meet the Telcordia Bellcore and CECC specifications, with a mating fee of ≤ 30N and an electrical current rating of ≤ 10A. AVX Corporation manufactures the connector.

Working Principle

To connect two or more PCB backplanes, the 1-445666-1 utilizes Edge Contact Technology (ECT). ECT uses spring-loaded contacts to make an electrical connection between two evenly spaced surfaces, such as the two sides of a PCB. ECT connectors are advantageous because, unlike conventional connectors, they require fewer connections, reduce signal attenuation, reduce cross-talk interference, and are less susceptible to electrical noise.

Features and Benefits

The 1-445666-1 offers a number of features and benefits. It has a robust design for demanding shock, vibration, and temperature environments. Its 45-pin configuration ensures a high-speed connection, and its edge contact technology ensures a reliable and secure connection. Finally, its spring-loaded contacts provide for a better signal integrity, requiring fewer connections and helping to reduce signal attenuation and cross-talk interference.

Conclusion

The 1-445666-1 is a high-performance and cost-effective backplane connector manufactured by ARINC. It is designed for use in demanding environments, such as military and aviation, and is particularly advantageous for applications where high bandwidth is need. Features such as edge contact technology significantly reduce cross-talk interference and signal attenuation, while allowing for a robust connection. As such, the 1-445666-1 is an ideal choice for many high-speed backplane applications.
