ARINC is an international standard that defines the general requirements for use of backplane connectors in aircraft systems. The global standard for backplane connectors, also known as IEC/ISO 1083, has been in use since the early 1980s and is still in use today. The primary purpose of the standard is to ensure interoperability between different types of backplane connectors, as well as facilitate the integration of new or modified systems.

The ARINC specification for the 208598-3 backplane connectors has been adopted by the industry as the main standard for use in aircraft systems. The specification defines the requirements for the design, materials, and performance of the backplane connectors. The design requirements include the physical dimensions of the connector components, as well as the environmental requirements such as temperature range, shock, and vibration. The material requirements include considerations related to electrical conductivity, resistance to corrosion and oxidation, temperature resistance, and other factors. The performance requirements refer to the performance, compatibility, and reliability of the connector, including the insertion and extraction of the contacts. The performance requirements also include the requirements for the mechanical strength of the connector.

The working principle of the ARINC 208598-3 backplane connectors is defined by the specification. The primary function of the connectors is to provide power and data signals between various components in an aircraft system. The power and data signals are transmitted through the contacts of the connected backplane components. The contacts are arranged in a specific configuration and provide a reliable connection between the backplane components. In order to ensure the connection between the backplane components, the contacts of the 208598-3 connector must be properly aligned.

In addition to providing power and data signals, the 208598-3 connector also provides protection against electromagnetic interference (EMI) and high-voltage transients. The EMI protection is provided by the use of a Faraday cage, which is made of two or more metal shields that protect the electrical signals from external interference. The high-voltage transient protection is provided by the use of a shield grounding system. This system consists of a shield, which is connected to ground, and a series of capacitors, which act as a transient suppression network.

The ARINC 208598-3 backplane connector is an important component in the aircraft system. The connector is designed to provide reliable power and data signals between different components in the system. The connector is also designed to provide protection against EMI and high-voltage transients. The connector’s design and working principle meet the requirements of the IEC/ISO 1083 standard, providing a reliable and safe connection between aircraft components.
