Backplane Connectors - Housings

Backplane connectors are a type of electrical connector that helps to define the physical characteristics of a backplane connection. Such connectors come in a range of configurations, and the 516-090-000-411 is a type of housing that are designed for use on printed circuit boards.

Design and Layout

The 516-090-000-411 is a stamped and formed component that is designed to fit securely and accurately on the top side of a PCB. The housing design includes four corner posts and two side posts that are spaced to accept dual row straight pc board contacts. The housing provides four mounting holes in the corner posts that permit secure mounting of the connector to the board. The housing also includes channels located on the inner sides that permit the insertion of contacts with up to a .047" box crimp termination. The height of the housing, when fitted onto the board, is approximately 0.755”.

Materials and Finish

The housing is manufactured from high-grade steel, which is then plated with a tin finish. The combination of steel construction and tin plating provides excellent corrosion protection and ensures that the mating surface remains clear and free of tarnishing. The housing also has a black oxide finish on the housing contact surface and a matt black passivation finish on the exterior of the housing. This multi-layer finish ensures that any contact damage is minimized, while protecting against corrosion.

Application Field and Working Principle

The 516-090-000-411 is suitable for use on a variety of circuit board designs, including those with rigid and flexible boards, all forms of microprocessor and analog/digital printed circuit boards, satellite and other space applications and performance boards. It is ideal for applications where high-speed and data transmission reliability is required.The working principle of the 516-090-000-411 is simple. When connected to a suitable pc board, the four corner posts of the housing provide secure and accurate mounting of the connector to the board. The two side posts provide guidance for the contact insertion during the assembly process, ensuring consistent contact placement. The interior channels provide secure contact retention by supporting the crimp terminal after crimping has taken place. The matt black passivation finish and oxide contact surface ensure minimal contact damage during the assembly process. This allows for secure and reliable connections that remain stable over time.

Conclusion

The 516-090-000-411 housing is a robust and reliable backplane connector. Its design features ensure that it provides secure and accurate mounting onto printed circuit boards, while its finish provides excellent corrosion protection. As such, it is suitable for a range of applications where speed and data transmission reliability is required.
