Backplane connectors and contacts form the critical link between processor boards and communications cards mounted in data processing systems. This type of contact enables reliable, consistent transfer of power and data signals through the interconnecting devices. The type of connection used for the connection suitable to each application depends upon the system architecture and the nature of the signal being transferred. This article provides an introduction to the 226782-1 interconnection system used in backplane connectior applications and explains its working principle.

226782-1 is a reliable, low cost, high-speed electrical solution provided by the Molex Company to address the need for rapid data transmission. The contact and connector system can be used in both single ended and differential backplane applications, and is suitable for applications which require data speeds up to 10 Gb/s. It is the first commercially available interconnector to successfully apply board-to-board differential techniques to create an extremely reliable and robust backplane connection.

226782-1 connectors are used primarily in computer systems which require high speed data communication. Common applications include high performance computing, storage array controllers, computer-to-storage systems and communication devices. It provides reliable digital signal transmission with low crosstalk and minimum skew. The connector includes contact elements that are designed to ensure minimal electrical losses and maximized signal integrity. The system features robust grounding protections to ensure interference-free data communication.

The unique feature of the 226782-1 system is its ability to maintain consistent performance over time. It can be used reliably in applications that require frequent and extreme environmental conditions, such as temperature and pressure fluctuations. The system is also designed to maintain a consistent electrical connection, and is therefore ideal for applications that require high speed data transmission.

The working principle of the 226782-1 system lies in its contact elements. The contact elements are placed in a series of slots on the contact structure. These slots create an area for the contact elements to migrate when heated, expanding, and contracting to accommodate thermal expansions or compressions. This arrangement allows for a uniform and constant electrical connection, which ensures that the signal being transferred is accurate and reliable.

In addition, the contact elements are designed to transfer current efficiently. The contact surface is designed to act as an insulator, allowing the current to flow through the contact system without any impedance or resistance. This helps to reduce power losses, maintaining a high signal integrity, and enabling the efficient transfer of data.

The contact elements are further reinforced by a unique mechanism known as J-stacking. This allows the contact elements to be connected together in a single connection at one side of the contact system, creating an interlocking structure which prevents the contact elements from vibrating, ensuring a consistent, reliable connection throughout the life of the system.

The 226782-1 connector system offers a reliable and highly efficient solution for data communication over backplanes. The system is robust, reliable and provides a consistent electrical connection, making it an ideal choice for high speed data communication applications. With its robust contact design and efficient electrical transfer mechanism, the 226782-1 system is sure to provide an exceptional performance for a long time.
