Binding posts are electrical connectors used to secure wires and cables in various devices and systems. They typically consist of a metal post with a threaded section and a knob or screw that tightens down on the wire, ensuring a stable connection. Binding posts are commonly found in audio equipment, laboratory instruments, and power supplies. These connectors are designed for easy access and quick connections, making them ideal for temporary setups or testing. They can accommodate different wire sizes and are often color-coded, with red indicating positive and black indicating negative, to help prevent wiring errors.
