Ring terminals are electrical connectors that feature a circular ring at one end, designed to be attached to a screw or bolt. This design ensures a secure and stable connection, making them ideal for various applications in automotive, industrial, and home wiring. They are typically made from copper or aluminum and are often coated with a layer of insulation to prevent short circuits. These terminals come in various sizes to accommodate different wire gauges and are commonly used in battery connections, grounding systems, and other electrical setups. Proper installation involves crimping the terminal onto the wire, ensuring a reliable electrical connection.
