Backplane Connectors - ARINC 1-208972-3 Application Field and Working Principle

ARINC 1-208972-3 connectors are a type of backplane connector used in aircraft applications, mainly for avionics and aircraft cabin systems. A backplane connector is a device that joins two assemblies together on a backplane, as the name suggests. Backplane connectors are used to transfer signals or power, but they also provide mechanical support and stability. ARINC 1-208972-3 connectors differ from other backplane connector types in that they are designed for use in cramped spaces due to their smaller size. They are also specifically designed to reduce weight while providing both high electrical performance and reliable contact reliability.

ARINC 1-208972-3 backplane connectors are mainly used in aircraft applications. The applications for these connectors include power systems, data bus systems, and instrumentation panels. These connectors are designed to handle a wide variety of applications, from low-power, short-distance connections, to high-power, long-distance connections. ARINC 1-208972-3 connectors are also commonly used in aerospace applications, due to their ease of installation and their high reliability.

The working principle of ARINC 1-208972-3 aircraft connectors is relatively simple. The connectors use a standard plug and socket configuration to provide the physical connection between the two assemblies. A plug on one assembly is inserted into the socket on the other assembly and locked into place using a locking mechanism. The connection is then made by a pair of contacts within the plug and socket as the plug is pushed in.

The ARINC 1-208972-3 connector utilizes three contact elements, including an insulated sleeve and two contact pins. The two contact pins have a number of unique features, including low contact resistance, high current carrying capacity, and low radiation emissions. The insulated sleeve provides a low impedance path for current flow, and helps to protect the contacts from vibration and other mechanical stress. The contact elements are also highly resistant to ceramic and airborne particles, making them resistant to corrosion.

The ARINC 1-208972-3 backplane connectors are designed to provide a reliable connection and performance in a small package. The size and weight of the connectors makes them an ideal choice for use in aircraft applications. The connectors are also designed to provide high electrical performance and reliable contact reliability. Additionally, they are designed to reduce weight while improving electrical performance.

Overall, ARINC 1-208972-3 connectors are an effective and reliable solution for power systems, data bus systems, and instrumentation panels used in aircraft applications. By optimizing the size and providing a high level of performance in a small package, these connectors can provide a reliable connection and performance in tight spaces. They are also designed to reduce weight while providing both high electrical performance and reliable contact reliability.
