A pin header and socket connector is a commonly used electronic connector designed to connect electronic components and circuit boards. It consists of a row of metal pins (pin header) and a corresponding row of sockets (socket connector).

A pin header is a type of metal pin, usually cylindrical, with one end inserted into a hole on an electronic component or circuit board, and the other end exposed to connect other components or devices. The shape and size of the pin header can be customized according to specific requirements.

A socket connector is a type of metal sleeve with an internal threaded structure that pairs with the pin header. The socket is typically fixed to the circuit board. Once the pin header is inserted into the socket, the threaded structure secures it in place, ensuring a reliable connection.

Pin header and socket connectors offer several advantages, including being pluggable, highly reliable, and easy to install and maintain. They are widely used in electronic devices, communication equipment, computers, and other fields.
