Backplane Connectors - ARINC 1883927-1 Application Field and Working Principle

ARINC 1883927-1 is a backplane connector specifically designed for use in the aerospace and defense industries. It was developed by the ARINC Research Corporation in 1996 and is a follow-on connector to the popular ARINC 627 and Mil-DTL-38999 backplane connectors. This connector was designed to address performance issues common to aircraft and satellites, such as size, weight, corrosion resistance, and extreme environmental conditions. The design of the connector helps to greatly reduce the chances of accidental disconnection, and its construction helps to ensure that the inserted pins resist mechanical shock and vibration.

The ARINC 1883927-1 backplane connector consists of multiple rows of connectors that connect to a backboard through threaded and/or crimped pins. The contact surfaces are made of corrosion-resistant metals that are molded into the body of the connector, making it resistant to environmental wear and tear. The number of pins per row varies depending on the application, with the most common size containing 50 to 60 pins per row. These pins are typically organized into two or three rows, and each row of pins is arranged into groups of 3 to 6 pins.

The working principle of the ARINC 1883927-1 backplane connector depends on two main components: the contact pins and the mating contact surface. The pins act as an electrical connection between the backboard and the device, conveying the electrical signals between them. The contact surface provides a secure, reliable connection between the devices, ensuring that the signals pass from one device to the other without any loss of signal.

The pins themselves are constructed from a variety of metals and alloys that are selected according to the application. Gold, copper, and nickel are some of the most commonly used materials,though other metals may be employed depending on the specific requirements of the application. For example, stainless steel may be used for applications that require corrosion resistance or large amounts of vibration. The pins also feature a rounded front and a sharp back, which helps to ensure that the pins do not vibrate loose and that the connection remains secure.

In operation, the pins of the ARINC 1883927-1 connector are inserted into the mating contact surface and compressed until a secure connection is made. The contact surfaces of the connector ensures that the pins remain in contact with one another and that electrical signals can flow between the two devices. This configuration also ensures that no connection is lost due to mechanical shock or vibration.

The ARINC 1883927-1 backplane connector is particularly well-suited for applications in aircraft and satellites, as well as other extreme environments. The connector\'s high-tolerance design and superior contact surfaces ensure that connections will remain reliable despite any environmental conditions, enabling the connector to handle higher voltage and power ratings. Further, the connector\'s resistance to corrosion and vibration makes it a suitable option for applications located in areas with extreme weather or harsh environmental conditions.

In summary, the ARINC 1883927-1 is a backplane connector designed for use in the aerospace and defense industries, featuring an array of pins arranged into multiple rows. The pins feature a rounded front and a sharp back, which helps to ensure that they remain securely inserted into the contact surface. The contact surface enables reliable electrical signals to pass between the two devices, and the connector\'s design provides reliable connections despite environmental conditions. This makes the connector well suited for any applications where reliable power or signal transmission is needed.
