Backplane connectors are components used in computers and other electronics equipment to connect circuit boards to each other or to a power or signal source. ARINC-type backplane connectors are used in applications requiring a high level of power or data transfer, as well as for automatic testing and rework. The first ARINC connectors were introduced in the late 1970s, and since then, they have become the industry standard. ARINC connectors provide a secure connection that is capable of withstanding high temperatures, high speed data transmission, and heavy electrical loads.

The 449838-1 backplane connector is one type of ARINC connector. It is designed for use in military avionics computers and other related applications. The connector has a military specification of AS5467 and is available in three versions. The 449838-1A is a straight-bodied connector, the 449838-1B is a right-angled connector, and the 449838-1C is a molex-type connector. It has contact pins of 0.038” created from gold plated copper, and contact pressure is 160#/sq. in. Its operating temperature range is from -55°C to +125°C.

The 449838-1 backplane connector consists of several main parts. The first is the insulation block which is made from a polymide material. It provides insulation from high voltage and other hazardous environmental conditions. The contact pins are made from gold plated copper, and provide superior electrical contact. The retaining clips, made from PTFE, provide a secure connection between the connection blocks and the circuit boards. The socket block, also made from PTFE, provides a reliable connection between the connection blocks and the circuit board.

The 449838-1 backplane connector works by providing a secure connection between the two circuit boards. The insulation block provides the necessary insulation against hazardous environmental conditions, while the contact pins provide a secure electrical connection. The retaining clips provide a reliable connection between the connection blocks and the circuit boards, while the socket block provides a secure connection between the connection blocks and the circuit boards. The 449838-1 backplane connector can be used for connecting circuit boards in computers, military avionics systems, communication systems, and industrial automation equipment.

There are two main advantages to using the 449838-1 backplane connector. Firstly, the connector has superior electrical and mechanical properties due to its gold plated copper contacts, PTFE insulators, and its high temperature rating. Secondly, the connector is designed to provide a secure and reliable connection between circuit boards while withstanding heavy loads and high speed data transmission. This makes the 449838-1 backplane connector the perfect choice for use in demanding applications.

In conclusion, the 449838-1 backplane connector is an ideal choice for applications requiring a reliable and secure connection between circuit boards. The connector is designed to provide superior electrical and mechanical properties due to its gold plated contacts, PTFE insulators, and high temperature rating. Additionally, the connector is designed to withstand high speed data transmission and heavy electrical loads, making it perfect for use in demanding applications.
