Backplane Connectors - Housings

Backplane connectors are electrical components used to provide a path for signal and power transfer between printed circuit boards (PCBs). They offer efficient interconnect solutions across a variety of board layouts, from standalone boards to board stacks, and are used in a broad range of applications. The 646478-7 is one such backplane connector designed to meet both the performance and reliability requirements of high-speed interconnects.

646478-7 Overview

The 646478-7 is a two-row, 30-signal backplane connector composed of a housing and contact system with two high-density arrays that are compliant to several industry standards. Its housing measures 38.6 millimeters deep and threaded for locking a cable into the backplane, making it ideal for using in systems where the cable needs to remain secure. It accepts 24 AWG to 28 AWG straight type cables, and its contact system is available in either through-hole or surface-mount assemblies.

Application Field and Working Principle

The 646478-7 is suitable for several applications, particularly for high-density applications wanting high-speed data processing, power distribution, and routing of power and ground connections. It also works well for mezzanine applications in which one board is stacked on another, and its compact size allows for up to 30 signal lines to be packed in a small space. Furthermore, the connector\'s housing features an insulated stand-off for additional insulation between boards and integrated locking screws.

The 646478-7\'s two rows are connected in parallel, resulting in improved signal integrity compared to conventional backplane designs. This is because signals have a more uniform trace impedance when laid out in paralleled traces, which helps eliminate potential ground loops, minimize signal reflections, and provide uniform power delivery. Moreover, the 646478-7\'s locking screws allow for cable flexibility and stability, enabling their use in higher power and data rate applications.

The 646478-7 can take on high frequency and data rate applications with its extended contact lifetimes due to its 12-positions and 24-positions contact design. The contact design provides a low resistance path for signals, thereby improving the connector\'s signal integrity and power efficiency.

Summary

The 646478-7 is a two-row, 30-signal backplane connector designed to meet high performance and reliability requirements. The two rows are connected in parallel to improve signal integrity compared to traditional backplane designs, and its contact design provides a low resistance path for signals. Furthermore, the connector\'s housing features an insulated stand-off and integrated locking screws for improved performance and cable flexibility. The 646478-7 is suitable for several applications, including high-density applications wanting high-speed data processing, power distribution, and routing of power and ground connections. It can take on high frequency and data rate applications with its extended contact lifetimes.
