Spade terminals are electrical connectors that have a flat, fork-like shape, resembling a spade. They are designed to connect wires to a terminal or a screw, allowing for a secure and reliable electrical connection. Spade terminals are commonly used in various applications, including automotive, industrial, and household wiring. These connectors are typically made of metal and are insulated with plastic to prevent accidental short circuits. To use a spade terminal, the wire is stripped of insulation, inserted into the terminal, and crimped to secure it. This makes spade terminals a popular choice for easy installation and maintenance in electrical systems.
