Rectangular Connectors - Headers, Male Pins

Rectangular connectors are electrical components used to connect two points in an electrical circuit. They are commonly used to bridge two power sources, forming a reliable connection between various electrical components. Rectangular connectors use pins to carry power and signal through a circuit, and these pins are typically arranged in a horizontal, parallel row. Among rectangular connectors, headers, and male pins are two of the most popular types due to their wide variety of applications.

Headers, and male pins are used most prominently in embedded systems since their small size make them ideal for limited space applications. The most common type of header, and male pin-shaped rectangular connector is D-subminiature, which is named after its features which are smaller than those of traditional D-shaped connectors. The basic components of the D-subminiature connector are a fixed female receptacle and a free male plug, which interact in pairs. A variety of sizes are available, ranging from 9 to 156 pins.

The working principles of headers, and male pins are divided into three parts. First, the pins of the headers must be properly aligned in the corresponding cavities of the female receptacle. Then, a plastic rib is inserted with one side latching to the female receptacle while the other side locks the male plug onto the female receptacle. After the male plug has been firmly locked, the power and signal pins are finally connected.

These rectangular connectors are often used in the production of computer printers, computer mice, calculators, photocopiers, and other electrical products. They are used to bridge the power circuit and signal circuit, providing reliable and safe transmission of weak signals that require precision. In addition, they are also widely used in industrial control systems, robotics, communications equipment, automobile industry, and so on.

At present, some modified versions of the D-subminiature rectangular connector have been developed. Such as the High Density D-subminiature (HD D-sub), which can provide up to 428 pins in a single connector. HD D-sub is typically used to transmit high density data flow, providing high performance and reliable transmission.

Headers, and male pins are lightweight and low cost, making them widely available. They are also able to withstand consistent insertion and withdrawal, providing good durability and reliable connection. Thanks to their extensive application fields and easily accessible components, these rectangular connectors have become the go-to choice for numerous industries.
