QFS-052-02-H-D-RA-K Application Field and Working Principle

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are high performance electric connectors widely used in electronic equipment, especially in computers and peripherals. The QFS-052-02-H-D-RA-K series is one of the most common types of connectors in this category. This article provides an overview of the application fields and working principles of the QFS-052-02-H-D-RA-K connector.

Applications

The QFS-052-02-H-D-RA-K series\' high-performance connectors are designed for applications that require high data transfer rates and reliability. These include applications in servers, routers, networking equipment, motherboards, DSCs, flash memory, communication and computing systems, and more. The connectors are also used in industrial/automotive applications where performance, heat dissipation, and durability are critical.

Working Principle

The QFS-052-02-H-D-RA-K series\' high performance connectors have a unique working principle that offers superior performance. The connectors are designed to use two rows of contacts with two or four contacts in each row. The contacts are routed through a pair of flexible PCB strips and then pressed into the connector\'s housing. This arrangement ensures that the contacts are held securely in place, eliminating the need for additional locking mechanisms.Additionally, the connectors feature an innovative design that minimizes vibration and improves energy efficiency. The connectors feature a “dual gap” feature which allows for a larger gap between the contact pads and the contact surfaces during connection. This effectively prevents the contacts from vibrating, which can cause electrical shorts. The contacts also have a unique plating system that offers improved contact retention and corrosion resistance.The QFS-052-02-H-D-RA-K series connectors are also designed to be highly electrically reliable. This is achieved by using an innovative design that prevents the contacts from contacting each other when in use, eliminating potential short-circuiting. The contacts feature gold plating to increase their electrical reliability, and the connectors have a unique grounding capability that provides improved noise immunity and signal integrity.

Conclusion

The QFS-052-02-H-D-RA-K series\' high performance connectors are designed specifically for high data transfer rates and reliability in servers, routers, motherboards, DSCs, and other specialty applications. The connectors feature an innovative, dual-gap design, along with gold plating, that reduces vibration and improves electrical reliability and signal integrity. Additionally, the connectors provide improved contact retention and corrosion resistance.
