Electrical connectors are used to make current between two devices to facilitate power supply and distribution, such as connections between electrical power cables. These terminals are insulated with rubber or plastic as a safety precaution due to high voltage. Clamping terminals are used if the connected device will use high voltages that need a safe electrical connection. Other uses include connecting one wire to another or several wires, connecting electrical appliances, electrical outlets, fuses or load switches, and connecting cables or overhead power lines.


Steel or iron cable terminals are high strength and used for stabilization of architecture, security cables and rigging. These terminals are built to withstand strong vibrations and achieve maximum support. Aluminum, metal, copper or lead cable terminals offer less resistance. These are usually made for electrical use or for non-stressed connections. Terminals with holes are used for the most resistive connections, as they allow a greater support of terminals without holes.


Cable terminations require a terminal with a side palm and are often used in external terminations. Connection of fuse sockets or disconnect switch requires a direct cable terminal with a flat or V-shaped terminal. Their forms also include long barrel terminals, tubular cable terminals, and annular terminals. . The variations in the shapes depend on the size of the connection being made. The terminal opening must be large enough to fit the connector or the connection will not form.
