445717-4 Connectors, Interconnects

ARINC (Aeronautical Radio, Inc.) 445717-4 backplane connectors are high-density, long-life power and signal connectors designed for standardization in wide area networks, telecommunication systems, local area networks, and avionics. With a robust design and excellent thermal performance, these connectors provide a reliable connection solution for harsh environments. The ARINC 445717-4 is a self-mating cable connector system that includes two distinct components. One is a male pin connector, which has a minimum of two rows of standard-sized aligned receptacles. The other is a female terminal plug, which has more than two rows of standard-sized aligned sockets. Utilizing ARINC 445717-4 connectors, backplane systems are able to support data transfer rates up to 10 Gbps depending on the operating environment.

Application Field

ARINC 445717-4 connectors are ideal for applications in military and aerospace, such as missile guidance, missile telemetry, aircraft flap control, weapons tracking, radar guidance, communication radios, transceivers, and antennas. They are also used in commercial applications, such as avionics traffic control, navigation systems, emissions control systems, fuel control systems, and industrial networks.

Working Principle

ARINC 445717-4 connectors are designed to provide a secure, low-resistance signal connection between two components. The contact pins are inserted into the female contact sockets, which are protected by high-impact plastic shells. The contact pins are then locked into place using a locking tab and mating latch. The contact pins are formed to ensure electrical continuity, as well as structural stability. The contact pins are separated by a dielectric spacer, which has a low dielectric constant that allows for reliable signal transmission.

The ARINC 445717-4 also has a current-carrying conductor that is isolated from the signal path. This ensures that power is dispersed evenly and reduces the possibility of malfunctions caused by high voltage surges. The contact pins are enclosed in a dielectric isolator, which ensures that no electromagnetic interference or noise can interfere with signal transmission. In addition, the cable connectors are sealed to ensure the utmost in environmental protection.

Conclusion

The ARINC 445717-4 backplane connectors are a safe and reliable way to transfer high-speed digital signals with low electrical resistance. Their robust construction and excellent thermal performance makes them an ideal choice for applications in extreme environments. These connectors offer a secure connection that is designed to ensure signal integrity and reduce the possibility of malfunctions. Additionally, the low dielectric constant of the contact pins and the high-impact plastic casing provide additional protection against environmental stressors. The ARINC 445717-4 backplane connectors are a cost-effective way to connect in harsh conditions.
