120524-1 Connectors, Interconnects

Rectangular Connectors, also known as receptacle connectors, are designed to provide interconnection between two PCBs. Commonly used in various industries and applications, rectangular connectors are used to reduce wiring complexity, minimize wiring and maximize assembly. In this article, we will discuss the different types of rectangular connectors, their main applications and working principles.

Arrays, Edge Type Connectors

Arrays, Edge Type Connectors are ideal for applications requiring the highest density connections and small physical size. They feature high level of proven reliability and fast connection points, along with connectors designed for PCB-to-PCB, FPC and Cable-to-Board connections. These connectors are suitable for the most demanding applications, including data/telecommunications applications. These connectors are available in multiple configurations, including through hole, surface mount and mixed technologies.

Mezzanine (Board to Board) Connectors

Mezzanine (Board to Board) Connectors, also known as Wire-to-Board (Mezzanine) Connectors, are designed to provide interconnectivity between two circuit boards. These connectors feature high-performance contacts that allow the circuit boards to connect securely and efficiently. Additionally, they provide robustness, flexibility, and reliability while also offering higher board stackability. These connectors are perfect for applications such as communication systems, industrial Ethernet and military/aerospace.

Working Principle

The working principle of a rectangular connector is based on contact pressure and a sliding motion. When the two parts of the connector are pushed together, the pin and contact points are compressed together, creating an electrical connection. Another type of contact is known as the “floating” contact, where no contact is made until the connector is inserted and comes into contact with the mating connector. This is ideal for applications that require frequent connection and disconnection.

Applications

Common applications of rectangular connectors include data transmission, communication and industrial automation. In addition, they are also used for applications such as medical and consumer devices, servers, appliances, transportation and aerospace. These connectors are also used in sophisticated data networks for reliable data transmission.

Conclusion

As can be seen from the above information, rectangular connectors are widely used in various industries and applications. By understanding the types of connectors, their applications and the working principle, it is possible to make an informed decision when selecting the appropriate connector for a particular application.
