US Patent 11791590 Magnetic cable connection device and adapator

A cable connection device includes a cable connector and a magnetic switch. The magnetic switch includes diametrically magnetized first and second annular magnets juxtaposed in a longitudinal direction of the cable connector and extending around a longitudinal axis of the cable connector, and an annular magnetic guide of ferromagnetic material surrounding an outer periphery of the first and second annular magnets. The first annular magnet is fixed relative to the annular magnetic guide, and the second annular magnet is rotatable between ON and OFF positions relative to the annular magnetic guide. In the ON position the first and second annular magnets are magnetically aligned in the longitudinal direction, and in the OFF position the first and second annular magnets are magnetically inverted in the longitudinal direction.
