Backplane connectors are used to make electrical connections between two points, such as between circuit boards, within a single or multi-board assembly. Such connections can be made through a variety of methods, including traditional wire-soldered solutions, high-speed transmission line systems, and pin or socket based connectors. ARINC?(Airbus Reconnaissance International Connectors) type of backplane connectors are widely used in avionics and aerospace applications. BKAE1-125-30010 is a type of backplane connector manufactured by Airbus. This article looks at its application field and working principle.

Application Field

As one of the most recognized backplane connectors, BKAE1-125-30010 is designed for use in avionics and aerospace applications where reliable, high-performance and long term electrical connections are required between internal circuits. Since it is rated for an operating temperature range up to 125°C,this connector is suitable for corrosion-resistant aerospace applications.

This connector also features an operating voltage rating up to 500V, allowing it to be used in many avionics and aerospace applications. Examples include high-speed data communications, aircraft control systems, power distribution panels, power control systems, etc. As an ARINC compliant connector, BKAE1-125-30010 can be used in many Airbus aircraft.

Working Principle

The BKAE1-125-30010 backplane connector is constructed with two pieces, a female and a male part. Each part comprises of two or more terminals which are used for electrical connection. In the case of the BKAE1 connector, each terminal contains three terminal pins plus an additional two power terminals or two grounding terminals.

To use the connector, the two pieces are plugged together, engaging all their respective terminal pins into the mating part. The outside shell of the connector is designed to provide a secure locking mechanism, ensuring the two pieces stay connected. Additionally, the connector features metal-to-metal contact for each terminal pin, providing maximum electrical continuity.

The BKAE1 backplane connector is also equipped with optional loop-through contacts, which provide an additional connection point between the two pieces. This allows for greater electrical safety and more reliable data transmission. Additionally, the connector can be used with a variety of insulation systems, from thermoplastic to silicone rubber.

Conclusion

The BKAE1-125-30010 is a reliable and high-performance backplane connector designed to provide a long-term electrical connection between circuits, making it an ideal choice for use in avionics and aerospace applications. This connector is constructed with two pieces, and features metal-to-metal contact for each terminal pin, as well as optional loop-through contacts for added electrical safety. This ARINC compliant connector can operate efficiently within an operating temperature range of up to 125°C, and an operating voltage rating of 500V.
