It is generally understood as the kind of electronic components that can be quickly connected by plugging or twisting the end of the male connector to the end of the female connector without using tools. Terminals are commonly understood as electronic products that require the use of certain tools, such as screwdrivers and cold-pressing pliers, to connect two connection points together. They are generally used for power input and output.
