Abstract
An electrical power coupler is configured to convey electrical power upon detecting that a compatible other coupler is properly aligned and no undesirable operating conditions are detected. The power coupler includes a first ferromagnetic metal adjacent a first magnet, a hall sensor for detecting a magnetic field in the first ferromagnetic metal, and at least two first electrical contacts. A control unit is in electrical communication with the power conductors, and includes an electrical switch operable to selectively allow a flow of electricity from a power source through the associated power conductors when the hall sensor detects the magnetic field, such as when the first electrical contacts are in contact with at least two second electrical contacts of another electrical power coupler. The second electrical contacts make contact with the first electrical contacts upon proper alignment of a correspondingly configured other electrical power coupler.
