A terminal is any fitting used for making a convenient electrical connection.
A terminal is any fitting or device used to make a convenient, secure electrical connection. It provides the point at which a conductor connects to a piece of equipment, a terminal block, or another conductor, allowing wires to be attached and detached reliably. Terminals come in many forms, including lugs, spade and ring terminals, screw terminals, and blocks, each suited to particular connection needs.
Because a terminal forms the junction between a conductor and the rest of a circuit, the quality of the connection it makes affects reliability. A good terminal maintains low resistance and a secure mechanical grip, and the conductor's finish, such as tinning, can aid the connection.
In commercial and industrial systems, terminals connect the many conductors of power, control, and signal circuits to equipment and to one another. Recognizing the term helps in understanding how cable is connected within a system.
