ARINC Inserts, particularly the 143-2086-001 product model, provide a solution to the issue of backplane connectors. These particular inserts are inserted into a plated through hole from the bottom surface of the board requiring a backplane connection, whereupon they provide a reliable terminated connection for signal transfer. As with other ARINC connector types, these particular inserts serve to bridge multiple layers of a Printed Circuit Board (PCB) while maintaining signal integrity where traditional through hole connections might be susceptible to crosstalk and other noise.

ARINC 143-2086-001 inserts feature a conductive shell construction with a small metal-plated bridge across the lower portion. This type of construction is required for providing electronic continuity as the electrical power and signal are transferred through the connector. Furthermore, the bridge minimizes the possibility of crosstalk between the different levels of the board as the adjacent signals travel through it. The other two components of the connector include a rubber gasket that seals the backplane connection and a tension spring that ensures a solid and reliable contact between the board and the connector.

The working principle of the ARINC 143-2086-001 backplane connector is quite simple, yet highly effective. The conductive shell acts as a waveguide for electric fields, thereby limiting the amount of noise generated by the connector. As the electrical power and signal travels through the connector, it is naturally affecting the environment around it. This causes a chain reaction where noise is created in response to the flow of power and signal to and from the board. The conductive shell acts as a shield, preventing this noise from entering the board and disrupting the signal.

Furthermore, when inserted, the tension spring applies pressure to the board. This serves to improve the connection, as it increases the contact between the PCB and the connector, and helps to dissipate heat generated by the connector. The rubber gasket also helps to ensure a secure connection when the connector is inserted, and provides an additional barrier between the backplane connector and the board.

The 143-2086-001 model of ARINC Inserts is also notable for its reliability, being designed and tested for long-term use. This is especially important for applications that require a robust backplane connection, such as those found in an aerospace environment. As such, these backplane connectors are widely used in applications that require a reliable, long-term connection.

In conclusion, the ARINC 143-2086-001 backplane connectors provide a reliable terminated connection for signal transfer. Furthermore, the construction of the connector, along with the rubber gasket and tension spring, help to ensure a secure connection between the connector and the board, as well as helping to reduce crosstalk and other noise from interfering with the signal. As such, they are perfect for applications that require a reliable, long-term connection, such as those found in the aerospace industry.
