202478-2 Connectors, Interconnects

Backplane Connectors - Housings

Backplane connectors are electronic devices used to connect or interconnect circuit boards. They are designed to handle power, data, and commands from one circuit board to another. Housings are components of backplane connectors that provide mechanical protection for the inner components and electrical lines.

The 202478-2 is a housing manufactured by Amphenol Corporation. It is an unshielded backplane connector system used to provide an efficient electrical connection between printed circuit boards (PCBs). The 202478-2 housing features an ultra-high density micro-strip array (MSA) connector with adjustable individual circuit contacts.

202478-2 Application Field and Working Principle

The 202478-2 housing is designed for use in high-speed board-to-board applications. It is suitable for use in high-performance computing and networking, as well as test and measurement applications. This housing system is available in various options including right angle, vertical, horizontal, and Z-axis configurations.

The working principle of the 202478-2 is similar to that of other backplane connector systems. The housing serves as the mechanical enclosure of the system’s components, while the electrical contacts provide the connection between the boards. Each contact is configured with an adjustable individual circuit contact that is able to provide the necessary connection between the boards.

The individual circuit contact is held in place by a spring-loaded socket which allows for precise control of movement. This ensures that a secure connection is established between the boards. Furthermore, the contacts are polarized to prevent incorrect connection of the boards.

The 202478-2 housing also provides improved EMI/RFI protection by using a shielded backplane system. This system provides isolation between the board-to-board connections, thus reducing any interference that may affect the performance of the system.
