Rectangular connectors are a type of electrical connectors used in a variety of electronics applications. They have a rectangular body, and typically contain integral contacts and mounting holes. Several types of rectangular connectors are available, including headers, specialty pins, and various types of hinged or printed circuit boards. In this article, we’ll explain the application fields and working principles of these connectors.

Headers

Header connectors are the most common type of rectangular connector, and are used for connecting various components within circuits. They consist of metal contacts in a plastic housing, which can be mated with other devices via two wires. The housing area can vary depending on the type of application, and may feature different levels of pins with different numbers of pins for different types of connections. Header connectors also come in different sizes, so that they can fit into different types of systems, such as appliances or electronic equipment.

Headers work by allowing the contacts to connect with the corresponding contacts on the other device. The connection between the header pins and the contacts on the other device provide an electrical connection that passes current from one to the other. The header contact pins are usually made of high-quality materials and electroplated to ensure a more secure connection. The plastic housing helps protect the header pins from dust, debris, and other contaminants.

Specialty Pins

Specialty pins are also a type of rectangular connector, but they are used for connecting specialized electronic components. They come in several sizes and shapes and are often used for connecting specialized components that do not fit on regular headers. Specialty pins can also be used to secure cables, as well as to provide an electrical connection between cables.

Specialty pins work by connecting the corresponding contacts on the other component and allowing a current to flow through. The pins are usually made of high-quality materials such as gold and silver alloys, and have different degrees of insulation for better protection. Specialty pins are designed to withstand the mechanical stresses of the environment they are being used in, as well as to provide a reliable electrical connection.

Hinged and Printed Circuit Boards

Hinged and printed circuit boards, or PCBs, are also a type of rectangular connector and can be used for connecting various components to one another.

Hinged circuit boards consist of printed connections soldered onto a metal board and then joined with hinges. The board is arranged in such a way that components can be attached to different points on the board. The connections on the board can then be used to connect the various components to one another without needing additional wires. This method is used for connecting components that do not fit on regular headers.

Printed circuit boards consist of a pattern of connections that can be printed or etched onto a non-conductive substrate, such as plastic. The patterns are made up of fine lines and dots, which are connected using a conductive material such as copper. The connections on the printed circuit board are then used to create electrical connections between the components.

Both types of rectangular connectors, hinged circuit boards and printed circuit boards, work by allowing current to flow from one component to another. The components are connected via the printed or etched connections, which provide a secure electrical connection between them.

Conclusion

Headers, specialty pins, and hinged and printed circuit boards are all types of rectangular connectors, and each of these types have their own unique application fields and working principles. Header connectors are the most common and are used for general purpose connections, while specialty pins and hinged and printed circuit boards are used for more specialized applications. All of these types of connectors allow for an electrical connection between different components, which is necessary for any electrical system.
