Rectangular connectors, specifically headers, male pins, are a type of electrical connectors that are generally used to join together individual wires or groups of insulation-covered wires. They are inserted into a rectangular housing or retaining block. The connectors provide a mechanical and electrical interface between mating circuits. The headers and male pins are used in a variety of applications, including computer and data processing systems, communication systems, consumer electronics, and industrial automation.

Working Principle

Headers and male pins are typically made of metal or plastic with the plastic version being preferred due to its low conductivity. The contacts are usually arranged in a one-row or two-row configuration. The contacts are usually held in place by a spring-loaded locking clip or a locking piece in the case of metal contacts. In the case of plastic connectors, the contacts are either soldered or molded onto the insulating housing.

The contacts are typically plated with gold or tin to ensure contact reliability. When the two parts of a header or male pin are mated, the connector is closed, creating an electrical connection between the two circuit components. The connectors can be disconnected by pressing down on a release button or by simply pulling the two parts of the connector apart.

Application Fields

The headers and male pins are used in a variety of applications, including computer and data processing systems, communication systems, consumer electronics, and industrial automation. Some of the most common applications are:

• Connecting cables to motherboards
• Connecting cables to circuit boards
• Connecting cables to various electronic components
• Connecting computer peripherals
• Connecting fans, motors, and sensors to control systems
• Connecting printed circuit boards in computers and other electronic equipment

Headers and male pins have become the most commonly used electrical connectors in the electronics industry because of their low cost, ease of installation, and reliable connections.

In addition to their use in computers and electronic equipment, headers and male pins are commonly used in automobiles, aircraft, industrial automation systems, and many other applications due to their low cost and reliable connections.

Headers and male pins are also used in the medical and robotics industries, as well as in the automotive and aerospace industries. They are used to connect sensors, motors, actuators, control systems, and other components in these industries.

Headers and male pins are also used to connect various types of communication systems, including cellular phones, internet routers, and satellite communication systems. They are used to transfer data and power, and they provide reliable connections between different components.

Headers and male pins are versatile and reliable connectors that are used in many different applications. They offer reliable connections, are easy to install, and are relatively low cost.
