QSH-120-01-L-D-A-K Application Field and Working Principle

The QSH series of connectors manufactured by Amphenol Industrial is a versatile, mezzanine-style connector with a broad application field. It is designed for conformal, board-to-board connections, as well as cabinet to module, and cabinet to cabinet applications. This type of connector provides an ideal solution to many industrial interconnect requirements, such as those found in datacom and telecom applications. It has been developed to offer high reliability, flexibility, and a long life span.

Design and Construction

QSH connectors are rectangular, edge type, mezzanine connectors. They feature a 2.550mm pitch and come in several different models. The connector comes in two parts, a male and female contact. It is designed with a shielded, metal body and a metal shell. It also features an 8-pin arrangement, with contact locations in the upper and lower rows of the connector. The contacts are implemented as machined pins that are inserted into insulated female receptacles. The contacts are designed to lower insertion forces and contact losses while providing high reliability, flexibility, and a long life span.

Working Principle

QSH connectors make their connection by inserting the male contact of one connector into the female contact of another. The integral pin contacts are constructed so that when the two connectors are mated, the pins are pulled into the mating contact and form a mechanical and electrical connection. This type of connector provides excellent retention, insulation, and flexibility. There is also a positive mechanical stop which limits the insertion of the contact into the receptacle. This prevents any pins from becoming partially inserted and causing shorts between the contacts. The pins can also be silver plated, so that an electrical connection can be established between the male and female contact.

Applications

QSH connectors are designed for use in various industrial applications, such as in automation and control, robotics, datacom, telecommunication, and industrial networking systems. They can also be used in computer applications, motion controllers, and power supply systems. The use of a QSH connector can help reduce the size and complexity of the connected system.

Benefits

QSH connectors offer many benefits, such as protection from environmental conditions, increased power handling capacity, improved reliability, a wide variety of connection options, and superb mechanical strength. They also have low contact resistance and high signal integrity, which helps to reduce electromagnetic interference and crosstalk. Furthermore, they have good insulation resistance and high insulation capacity. Finally, they are highly resistant to shock, vibration, and extreme temperatures.

Conclusion

QSH connectors provide a reliable, high-performance alternative to many industrial interconnect solutions. With their robust design and superior insulation and power handling capacities, they are ideal for many datacom and telecom applications. These connectors provide excellent retention, insulation, and flexibility, as well as a positive mechanical stop that prevents any pins from becoming partially inserted. They are also highly resistant to shock, vibration, and extreme temperatures, making them desirable in many industrial applications.
