Backplane Connectors are an important part of any electronic system, providing high-speed and low-latency transmission of data between different subsystems. The 5646857-1 is a type of backplane connector designed to deliver high-performance and reliable connections in harsh automated equipment and intricate electronic subsystems. This article will describe the application field and working principle of the 5646857-1.

Application Field

The 5646857-1 is a high-density 2.54mm pitch backplane connector system designed for automated equipment. This connector is capable of withstanding the vibrational forces encountered in such equipment without degrading its performance. It is suitable for applications in areas such as aerospace, instrumentation, industrial automation, and communication systems. The 5646857-1 is compatible with many types of PCBs and is EMI-resistant, making it ideal for use in environments where electromagnetic interference is a concern.

Due to its high termination densities, the 5646857-1 is commonly used in infrastructure and telecom applications where space is limited. It is also useful in situations where there is a need for multiple power and signal connections in a short amount of time. This makes it an ideal choice for high-density equipment such as servers, switches, and cellular base stations.

Working Principle

The 5646857-1 backplane connector uses a set of gold-plated, non-rotating contacts. These contacts are designed so as to evenly spread the signal over the entire surface area of the connector, reducing electromagnetic interference and cross-talk. The contacts are also designed to provide a low-impedance connection to switch integrity and reduce signal reflections. The contacts are firmly held in place by the connector\'s clip-in housing and are prevented from rotating even under extreme vibrations.

The contact block of the 5646857-1 consists of a black plastic dielectric and a white plastic guide station. This guide station aids in correctly aligning the contact block to the PCB, thus improving the connector\'s signal integrity. The contacts are mounted within this contact block and an insulating washer seals the contacts in place, preventing them from moving. Once the contact block is properly installed on the PCB, the housing is secured to the connector assembly using a locking mechanism.

In addition, the 5646857-1 is designed to provide redundant contacts for power and ground connections as well as screen continuity. This helps to ensure that the signal and power are protected from potential damage due to external influences. This type of connector is also capable of conducting both shielded and unshielded signals, allowing for flexibility in its application.

Conclusion

The 5646857-1 backplane connector is designed to provide reliable and high-performance signal and power transmission in harsh automated equipment and telecom systems. Its gold-plated non-rotating contacts ensure low-impedance connections and provide signal integrity as well as EMI-resistance. The connector also has redundant contacts for power and ground connections and can conduct both shielded and unshielded signals. This makes it an ideal choice for applications in areas such as aerospace, instrumentation, industrial automation, and communication systems.
