ARINC (Aeronautical Radio Incorporated) backplane connectors are an important variety of connectors used in a variety of applications, including aircraft applications. The 1883734-1 model is one of the many connectors in the ARINC range, and is designed for specific applications, chiefly those associated with avionics systems. This article will discuss the characterizing elements of the 1883734-1, its application field and working principle.

Characteristics of the 1883734-1 ARINC Connector

The 1883734-1 ARINC backplane connector was designed by the Binder Group GmbH & Co KG company for use in avionics systems. As a backplane connector, it is designed to connect multiple printed circuit boards (PCBs) in order to achieve increased data speeds, small physical size, and increased overall reliability. The 1883734-1 is characterized by being shock and vibration-resistant, making it suitable for the arduous conditions found in an aircraft. It functions across a temperature range from -55°C to + 125°C and is similarly pressurization-resistant, allowing it to survive a pressure range of 1.10^-7 to 13.7 Pa. With regards to physical measurements, it has a contact separation of 0.7mm and a maximum pin count of 160.

Application Field of the 1883734-1

The 1883734-1 ARINC backplane connector was designed mainly for use in avionics systems, however its shock and vibration-resistance capability has seen its use expand beyond aircraft applications to many other arenas. As an example, it can be found in medical and laboratory applications, where its precision performance is essential due to its incorporation of proven contact technology. It has also been used in military radio systems, where its dimensions are no larger than necessary in order to better fit in tight constricted areas.

Working Principle of the 1883734-1

The 1883734-1 ARINC backplane connector collects signals from other sources in order to produce a summation of input signals that are then sent to the output. This is achieved through the design\'s 9-row matrix layout, which ensures that all contact wires of differing signals are routed to the same target socket.

The 1883734-1 ARINC backplane connector is designed to prevent interference between signals, and also protects against data loss due to contact bouncing. To achieve this, the pins are designed in a configuration where they are offset from each other. This design provides prevention against signal interference via a double-pin layout where the signal wire of one socket will not come into contact with the signal wire of the adjacent socket, thus producing a short circuit. This double-pin layout also ensures anti-bouncing prevention, where the contact materials of each pin are designed at a slight angle so that two contacts can slide underneath to prevent any contact bouncing.

Conclusion

The 1883734-1 ARINC backplane connector is a reliable and precise connector that is used for a variety of applications, especially in avionics systems. It is characterized by its vibration and shock resistance, as well as its ability to function within a wide temperature range and still maintain pressurization. The 1883734-1 also has a double-pin layout that helps to prevent signal interference and contact bouncing, and is able to collect and route signals from a wide range of sources. This makes the 1883734-1 ARINC backplane connector an ideal choice for a variety of applications.
