Backplane connectors are a common form of interconnect technology used to provide power and communication signals between major components in a printed circuit board (PCB) system. The 2057443-2 is a specialized type of backplane connector designed to meet the needs of high-speed data communication systems. This article addresses the application field and working principle of the 2057443-2 backplane connector.

Applications

The 2057443-2 backplane connector is a compact, low profile, high-speed data communication connector designed for high density, space-constrained applications. Its vertically aligned contact design allows for increased data rates in comparison to other connector standards. It is widely used for high speed and/or high density applications such as telecommunications, data communications, networking, storage, and computing. This connector type also has high reliability requirements and is routinely used in rugged, long-life applications. It is also used for medical, aerospace, and military-level systems in order to comply with the most stringent environmental standards.

Working Principle

The 2057443-2 backplane connector consists of two parts, an upper portion and a lower portion, and requires several accessories to function. On the upper part, two rows of solder cups surrounded by a plastic housing provide electrical connections between the mating pairs. The copper cups on the lower part provide mechanical connections to the mating board. It also contains two long pins to ensure proper electrical engagement when the upper parts are mated. The upper and lower portions of the connector are placed over each other and joined together by a retaining clip, providing a secure mechanical connection.

Once joined, the electrical connection is accomplished through the contact of metal surfaces against each pin. This contact is governed by a combination of insertion force, contact pressure, temperature, and relative motion between the male and female connectors. The electrical connection is also maintained by a spring present in the contact pins. The combination of these forces ensures that the connection is stable even under high vibration and dust/debris environments, making it suitable for long-term robust applications.

Conclusion

The 2057443-2 backplane connector is a specialized type of backplane connector designed to meet the needs of high-speed data communication systems. It is widely used for high speed and/or high density applications like telecommunications, networking, storage, and computing. It has high reliability requirements with excellent electrical and mechanical specifications. Its combination of insertion force, contact pressure, temperature, and relative motion between mate pins allows for robust, long-term connections even with high vibration or dust/debris environment applications.
