Backplane Connectors - ARINC

213434-3 Application Field and Working Principle

ARINC (Aeronautical Radio, Inc.) is the leading supplier of connectors, backplane connectors, and backplanes for the commercial aircraft industry. The 213434-3 backplane connectors are designed to meet the rigorous demands of aircraft reliability, strength, and performance.

The 213434-3 application fields include aircraft interiors, avionics systems, and other aerospace applications. It is ideal for applications requiring robust connections, superior thermal cycling, and shock and vibration resistance.

ARINC 213434-3 backplane connectors are composed of two parts: the receptacle connector and the plug connector. The receptacle connector is installed into the mating face of the aircraft backplane and consists of an outer insulator sleeve, an inner contact assembly, and contact pad. The plug connector is designed to mate with the receptacle and consists of an outer insulator sleeve, a contact assembly, and wire leads.

The 213434-3 backplane connectors feature a dual-key system, which ensures a secure connection for optimal safety and reliability. The two keys on the plug connector engage two slots on the receptacle connector when the plug connector is inserted. This dual-key system prevents accidental mismating and ensures that the connection is secure. The contact pads on the receptacle connector and the contacts on the plug connector are designed to create a high-level connection.

The 213434-3 application also features a unique crimp-and-clamp retainer system, which guarantees a strong electrical connection and reliable performance. This retainer system creates a secure connection between the contact pad and the end of the wire lead, preventing the wire from becoming loose due to vibration and shock. The wire lead is then clamped onto the contact pad, creating a secure connection with the contact pad and ensuring a consistent electrical connection.

The 213434-3 application also features a superior electroplated finish, which provides an extra layer of protection against oxidation and corrosion. This electroplated finish prevents electrical signals from travelling between contacts, prevents flashover, and ensures reliable electrical performance. This superior electroplated finish also ensures that the contact is not subject to fretting corrosion and maintains a good-looking appearance.

ARINC 213434-3 backplane connectors provide superior reliability and performance for aircraft interiors, avionics systems, and other aerospace applications. With its unique dual-key system and superior electroplated finish, this application provides a strong electrical connection, reliable performance, and a long-lasting finish. These features ensure that the backplane connectors will provide long-term service and satisfaction.
