Backplane connectors, referred to as BP or BPCs, are components used to securely mount and connect two or more printed circuit boards (PCBs) together. The 5646764-1 is a type of backplane connector that falls into the category of hard metric, standard connectors. Below, we will explain their application field and working principle.

Application Field

The 5646764-1 is a standard hard metric backplane connector designed for use in a wide range of electronic assembly applications, from industrial to consumer. It is most commonly used as an interposer connector, which serves to connect two PCBs, allowing for data and signal transfer between them. This backplane connector type is also suitable for applications that require a robust and secure connection between two or more layers of circuit boards and is particularly appropriate for applications that feature frequently changing connections. Examples of its applications include computer drives, industrial systems and handheld devices.

Working Principle

The 5646764-1 backplane connector follows the standard hard metric connection concept, with a pin-and-socket connector system. The system utilizes a locking mechanism, typically a sleeve lock, to tightly secure the two mating components together. The pin plugs, or wires, of the connector are held together with a guide concept on the mating faces, that is, two rows, with the inner row slightly shorter. Once the two components are fully engaged, the locking sleeve positioned between the two components is then tightened with a predetermined torque to firmly pull the two components together and secure the connection.

The 5646764-1’s key features making it suitable to be used in interposer configurations include high-current and high-voltage ratings, 6 to 72 contacts configuration, and 1.27mm pitch size, which helps to reduce client assembly costs. This backplane connector also offers design flexibility, with high-density designs and optional mounting surfaces.

Conclusion

The 5646764-1 backplane connector is a standard, hard metric connector designed for use in a wide range of electronic assembly applications. Its key features that make it suitable for interposer configurations include high-current and high-voltage ratings, 6 to 72 contacts configuration, and 1.27mm pitch size. It is easy to install and provides a secure, reliable connection between products that often feature frequent connection changes.
