Rectangular Connectors - Headers, Male Pins

Rectangular connectors are electrical components used for securely joining two or more cables together. They are designed to withstand constant voltage and provide an electrical connection during device activation. Within the rectangular connector systems, headers, male pins, female sockets and boards are the main components for forming the connections. Headers are rectangular connectors, which consist of a cylindrical metal male pin at one end, and a plastic connector housing at the other. They are designed for connecting two different cables. Headers are used in the construction of electronic circuits and signal connections. Male pins are the contact points on header connectors. They are made of metal, usually either stainless steel or copper, and can have various diameters and lengths. Male pins are usually terminated by soldering them to the circuit boards. When they are properly connected, the metal pins make contact with female sockets, creating a circuit. The 4-102978-0-28 rectangular connector is a patented design in this field. It has a pin pitch of 2.54mm, and is designed for connecting two PCBs by wire-to-board applications. The design ensures the stability and reliability of the electrical connection between the parts. The working principle of the 4-102978-0-28 rectangular connector is quite simple. When the two connectors are pressed together, the male pins will penetrate the female sockets and make contact with the conductive element inside. This creates an electrical connection, allowing the connected devices to function as intended. The male pins and female sockets of the 4-102978-0-28 are made from high-quality materials that can withstand continuous voltage. The stability of the connection can be further enhanced by using shields or jumper wires to bridge contacts. The design also features anti-vibration and anti-corrosion features, making it suitable for a wide range of applications and environments. Overall, the 4-102978-0-28 rectangular connector is an efficient and reliable way to form an electrical connection between two parts. It features a simple design and is suitable for a variety of applications. With its solid construction and stable connection, it is perfect for wire-to-board connections in a wide range of applications.
