  • Electromagnetic coupler
    Patent number: 10465450
    Abstract: An electromagnetic coupler includes first and second coupling elements for mounting on respective first and second support elements. The first and second coupling elements include respective first and second annular bodies each including a high magnetic permeability material that houses a conductive winding and an open transverse section. The first and second bodies have complementary shapes that when two support elements respectively receiving the first and second coupling elements are coupled, the first and second bodies form a structure enclosing the first and second conductive windings. The first and second conductive windings are respectively positioned in the first and second bodies such that respective surfaces of the first and second conductive windings are substantially parallel when two support elements respectively receiving the first and second coupling elements are coupled.
