Rectangular connectors are electrical connectors which are designed to join multiple wires or printed circuit boards together. Arrays, Edge Type, Mezzanine (Board to Board) are the three types of these rectangular connectors, among which QMS-026-05.75-L-D-A-RF1 belongs to the Mezzanine (Board to Board) type. Its application field and working principle are as follows.

Application Field

QMS-026-05.75-L-D-A-RF1 is a mezzanine level interconnect system, which is featured by its high reliability and durability. It is a widely applicable product, mainly used in PCB applications such as consumer electronics, data communication, medical instruments, industrial control equipment, mobile phones, digital products, and automotive components. It is suitable for both through-hole and surface mount devices. Furthermore, this mezzanine system offers excellent performance in high density applications.

Working Principle

QMS-026-05.75-L-D-A-RF1 adopts a stacked structure, which couples two PCBs with a female-male matching connection. It includes a top board, a bottom board, and a male-male connector that serves as the top-to-bottom link. The top board is put on the bottom board and locked by the latches. The contact surfaces of the male-male connector is formed of contacts legs which spring to resistant force against outside force. The internal contact resistance is minimized when connected. In addition, the contacts are gold plated, which ensures proper electrical connection and prevents oxidation.

Conclusion

QMS-026-05.75-L-D-A-RF1 belongs to the Mezzanine (Board to Board) type of the Rectangular Connectors family. It is used in wide variety of applications, such as consumer electronics, medical instruments, and digital products. It adopts a stacked structure and a female-male matching connection. To fight against oxidation, its contacts are gold plated. Therefore, its application field and working principle guarantee its excellent performance in the high density applications.
