Rectangular board-to-board connectors, including headers, receptacles, and female sockets, are integral components in modern electronic assemblies. These connectors are designed to facilitate reliable and removable connections between different circuit boards within a device. Their primary function is to transmit signals or power from one board to another, enhancing modular design and simplifying assembly and repairs. Typically found in computers, communications equipment, and medical devices, these connectors are valued for their versatility and durability. They come in various configurations and pin counts to suit different applications, ensuring a stable and secure connection while enabling easier upgrades and maintenance of electronic systems.
