US Patent 9705243 Electronic connector with C-shaped tapered extension

An electronic connector comprises a base, a tapered extension protruding from the base, and one or more magnets. The tapered extension includes a first connection face parallel with a first symmetry plane of the tapered extension, a first set of electrical contacts on the first connection face arranged symmetrically about a second, orthogonal symmetry plane of the tapered extension, a second connection face parallel with the first symmetry plane and facing the first connection face, and a second set of electrical contacts on the second connection face arranged symmetrically about the second symmetry plane. The tapered extension further includes first and second outer surfaces, first and second noses, and set of flank surfaces defining first and second sides of the tapered extension, where the first and second outer surfaces taper away from one another and the first and second sides taper away from one another toward the base.
