Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are an important part of the electronics industry, used to connect electrical components. They can be classified into types such as headers, receptacles, and female sockets. The 0022173256 application field and working principle are two important aspects to consider when choosing the correct rectangular connector for a particular application.

Header Rectangular Connectors

Header rectangular connectors are commonly used in wire-to-board applications, for connections between coaxial cables and printed circuit boards. They provide a suitable mating interface for external wiring, both to provide power and signal connections. A wide range of designs exist, with backplane and mezzanine connectors for power and any number of parallel contacts for data cables. Headers are typically constructed from an insulating material, which is then wired via a series of pins or sockets. The necessary contact between the pins and the board is provided by a spring mechanism. This means that the header is able to ”flex”, which is essential for the connection to remain secure. The working principle of the header is simple. The pins are connected to the board, and the forces exerted by the spring mechanism ensure the connection remains secure. The pins and sockets are in contact with each other, and this ensures that any data can be passed back and forth.

Receptacle Rectangular Connectors

Receptacle connectors are most often used in industrial and commercial applications where it is necessary to provide a durable connection between boards. The receptacle connector is designed so that it can be used with customized screws, hooks, clips and other fasteners. The working principle of this type of connector is fairly simple. The components and wiring are connected to the receptacle base, and then a dedicated latch is used to secure the connection.Receptacles are also available in a wide range of configurations, including flush and right-angle designs. The flush design is most often used in applications where the overall profile needs to be kept as low as possible, while right-angle designs are ideal for applications where the connections will be exposed to environmental elements.

Female Sockets Rectangular Connectors

Female sockets are commonly used in applications where signal transmission is necessary, but the external conditions may be less than ideal. This type of connector is typically used for automotive, networking and consumer electronics applications, where connection speed and reliability are paramount. Female sockets are designed with a two-piece construction, with the upper piece containing the contact pins and the lower piece having an array of sliding contacts. These contacts ensure that the signal is correctly transferred from the pins to the lower piece, and that no interference is present.The working principle of the female socket is slightly different than that of the other two types. In this case, the socket and lead are connected via a pair of plated contacts. These contacts provide a stable connection, and prevent any interference from the outside environment. The contacts are constructed from an insulating material, and the entire connection is then sealed to prevent dust or moisture from affecting the connection.

Conclusion

Having examined the 0022173256 application field and working principle of rectangular connectors, we can conclude that these versatile connectors are suitable for a wide range of applications. Headers are perfect for wire-to-board connections, while receptacles are best suited for industrial applications. Finally, female sockets are perfect for high-speed signal transmission, where interference must be avoided at all costs. In addition, they are constructed from materials that are able to withstand harsh environmental conditions.
