Common connector types include plug and socket connectors, threaded connectors, and quick-connect connectors. Plug and socket connectors are the most common type, featuring matching plugs and sockets for easy and quick connection and disconnection. Threaded connectors provide stable current transmission and connection through threaded connections, while quick-connect connectors use a quick-plug design for easy and rapid tool changes.
