Rectangular Connectors - Headers, Male Pins 

Application Field and Working Principle

Rectangular connectors, also known as headers and pins, are an important form of electrical interconnection. They are used for a variety of applications, including power and signal transmission, as well as for connecting wires and components. Headers and male pins can also be used for ground planes and as common point power connections on printed circuit boards.

Headers and male pins are typically made from materials such as copper-clad steel or tinned brass, although other materials may be used as well. As the names suggest, these connectors consist of a header that connects to female sockets or pins, while the male pins fit into female sockets.

There are many different types of rectangular connectors. Some of the most common are:

• Pin headers – These connectors have two or more rows of pins that fit into female sockets or plugs, usually used for power or signal connections.
• Socket headers – These connectors have two or more rows of female sockets that accept male pins, usually used for power or signal connections.
• Pogo pins – These connectors have a single row of male pins that fit into female sockets, and can be used for high-frequency signals and quick connectors.
• Header plugs – These connectors have a single row of female sockets that accept male pins, and can be used for quick connections.

The working principle of these connectors is fairly straightforward. When the male pin is inserted into the female socket, it makes contact with the connector\'s inner surfaces, which then create an electrical connection. The connection is maintained by the friction between the male pin and the female socket, which is held in place by the connector\'s material.

Rectangular connectors are used in a variety of applications that require power and signal transmission, as well as quick-connect and disconnections. In addition, they are often used in harsh environments where other types of connectors may fail due to corrosion, vibration, etc.

Overall, rectangular connectors are an invaluable interconnection component for a variety of electrical devices and applications. They are extensively used in industries such as manufacturing, transportation, medical, aerospace, and automotive, among others. They are reliable and easy to install, and are available in a wide range of sizes and styles to meet different requirements.
