Backplane connectors are a type of electronic component which can be used to connect boards and cables in order to transfer power and data signals in a circuit. ARINC 449587-4 connectors are among one of the many varieties of backplane connectors available, and they have specific advantages and features that make them great for some applications over others. This article will go into the field of application and working principle of the ARINC 449587-4 connector.

Overview

ARINC 449587-4 is a type of mini-backplane connector which complies with the technical standards of the Aerospace Industries Association (AIA). It is part of a series of several similar mini-connectors developed for specific applications in the aerospace industry. It is capable of carrying up to 4.3A of current and is designed to be compatible with existing backplane connectors. The connector is used to mechanically couple printed circuit boards to the backplane and carries a signal from one board to the other. It has a 2mm aluminum shroud, a machined steel latch, and an edge mounted pin-in-socket design. It also features 5-row connection with a total of 72 contacts.

Field of Application

ARINC 449587-4 connectors are most commonly used in the aerospace industry, particularly for the connection of Circuit Cards Assemblies (CCAs) on backplanes and within racks. The connectors can also be used in ground military and test equipment. The connector is ideal for use in applications where the size, weight, and frequency of operation are critical factors as it can transfer large amounts of data in the shortest amount of time. Its small size also makes it ideal for applications where space is limited.

Due to its design and size, the ARINC 449587-4 connector is also suited for high density applications, including data as well as power connectors. It is capable of carrying higher currents in a compact form factor. It is also designed with a special latch mechanism that helps to ensure a secure and reliable connection in vibration applications.

Working Principle

The ARINC 449587-4 connector utilizes a pin-in-socket design which is lightning-fast and provides for reliable and dependable connections when compliant with the appropriate specifications. The connector has two types of contact configurations, one on the bottom of the connector and one on the top. The bottom contacts are arranged in a five-row configuration which provide for high-speed transmission. The top contacts are arranged in a seven-row configuration which ensures that the proper signal is sent to the backplane board.

The connector design also features spring loaded pins which help ensure a secure connection even in the presence of vibration, shock or extreme temperatures. The latches used in the connector provide additional strength to ensure vibrations or shocks are not transmitted to the device. The position of the latch also helps to ensure that the connection is in the correct position each time it is connected.

Conclusion

The ARINC 449587-4 connector is a mini-backplane connector that is designed for the aerospace industry. It is capable of carrying up to 4.3A of current, and is designed with a 2mm aluminum shroud, a machined steel latch and an edge mounted pin-in-socket design. It is well suited for applications where size, weight, and frequency of operation are important considerations, and is commonly used in CCAs, ground military, and test equipment. The connector also utilizes a pin-in-socket design which provides for reliable and dependable connections in the presence of vibrations, shock or extreme temperatures.
