Introduction

The 85674-1138LF Backplane Connector, also known as a board-to-board connector, is designed for deployments where electrical and mechanical performance requirements must meet high industry standards. This connector is part of the larger 85674 series of high performance backplane connectors from Hewlett Packard which is used in many industries across the globe.

Design and Applications

The 85674-1138LF backplane connector is designed for use in applications that require a high level of electrical performance and mechanical reliability. It is designed to meet the rigorous requirements of the telecommunications, industrial, medical, and automotive markets. This connector provides reliable connections in high speed digital equipment. This connector is also compatible with many high speed digital boards, such as low profile VMEs, CompactPCI, PMC, PCI Express, and PCIe.The 85674-1138LF features a true differential mode of operation with contacts that are gold-plated. It has a standard 18 AWG lead wire with an 18-contact pin contact arrangement that ensures low electrical losses. Additionally, the connector has a double insulator construction, making it suitable for maximum thermal performance and robustness in harsh environments.

Working Principles

The 85674-1138LF backplane connector is designed to provide reliable high-speed performance for board-to-board connections. Its reinforcing metal pins and dual insulating construction make it ideal for harsh environment applications.The 85674-1138LF consists of five different contact types including: signal contacts – designed to carry signal and power, compression contacts – designed to carry signal and data return paths, and an integrated keying system which helps correctly align the connector during mating.The connector’s metal pins are designed to provide superior performance as well as reliable, repeatable, and consistent insertion and withdrawal forces. The structure of the pins ensures a reliable, self-cleaning electrical contact. Additionally, the several contact points on each pin help reduce mechanical and electrical contact resistance.The 85674-1138LF also features an integrated strain relief that allows for secure fits and high-durability. This strain relief helps protect the connector from bending and deforming forces which can cause additional wear and tear in addition to electrical malfunctions.

Conclusion

The 85674-1138LF is a reliable high-speed electrical connector from Hewlett Packard taken from the larger 85674 series. It is designed to offer superior performance in high speed applications with features such as gold-plated contacts, dual insulating construction, and an integrated keying system. The metal pins have a self-cleaning design to ensure reliable electrical contact and it also features an integrated strain relief for secure fits and increased durability. The 85674-1138LF is ideal for harsh environment deployments that require frequent high-speed transfers of data between devices.
