Backplane Connectors - Contacts: 448543-2 Application Field and Working Principle

Backplane connectors are essential components in backplane applications due to their capabilities for high-speed data transmission, low-profile and compact layout, reliable connection, and cost-effective solutions. The 448543-2 backplane connector is a widely used product due to its robust design and flexible sizing capability. This article summarizes the application field and working principle of the 448543-2 Backplane connector.

Application Field

The 448543-2 backplane connector is designed to be used in high-speed applications that require reliable and fast data transmission, such as Servers, RAID and SATA HBA, Network switches, Enterprise storage systems, Direct Attached Storage (DAS) systems, etc. Additionally, the connector is a perfect choice for blind-mate applications due to its low-profile and reliable mating force. It can also be used in wide variety of applications due to the flexible pin configuration and insulation displacement contact option.

Working Principle

The 448543-2 backplane connector consists of two parts; a plug and a receptacle. The plug is a connector with a number of pins that are designed to fit into the receptacle which is a plastic housing with a number of cavities to receive the pins. The pins on the plug are held captive by a positive locking mechanism. This ensures that there is minimal disconnection during assembly and operation. When the connector is mated, the contact fingers of the plug are inserted into the mating points of the receptacle and make electrical contact. The 448543-2 backplane connector is designed to provide reliable point-to-point contact. It is a gold-plated, high-speed, low-current wire-to-board connection with the ability to accommodate up to 30A of current per contact. The contact fingers are designed in a round or flat shape which allows a strong and reliable connection. The contact fingers are spring loaded and mated with the corresponding cavities of the receptacle. When the connector is mated, the contact fingers make electrical connection with the mating pin thus providing reliable electrical connection.

Conclusion

The 448543-2 backplane connector is designed to provide high-speed, reliable connection for data systems. It is designed for use in high-speed applications that require reliable and fast data transmission. The connector is a perfect choice for blind-mate applications due to its low-profile and reliable mating force. Additionally, the connector is designed with a positive locking mechanism to ensure minimal disconnection during assembly and operation. Lastly, the contact fingers of the connector are spring loaded and mated with the corresponding cavities of the receptacle to provide a reliable electrical connection.
