Female connectors, also known as Machined Pin Headers, Printed Circuit Board (PCB) Connectors, socket connectors, or female connectors, are a type of electronic component connector. They come in two varieties: SMD & Dip Contact Pad (Single Pin) and Multi-Contact Female Connector. These are used in conjunction with corresponding male connectors or pin headers to facilitate connections between circuits. Female connectors feature grooves or holes to accept the protruding pins of male connectors.

Female connectors are widely used in various electronic devices and circuit boards, such as computer motherboards, mobile devices, home appliances, and industrial control systems. They can be used for power or signal transmission and are designed in multiple shapes, sizes, and pin configurations to meet different technical requirements and application scenarios.

Female connectors can be attached to circuit boards through soldering or crimping and can be designed to support hot-swapping, meaning they can be plugged and unplugged while the power is on without damaging the circuits or components.
