As reported by Patently Apple, Apple (NASDAQ: AAPL) recently received a Granted Patent covering its MagSafe connector and power adapter. As shown in the patent figures (below), Apple's proposed 60 Watt MagSafe Power Adapter reportedly "features a magnetic DC connector that ensures that the power cable will disconnect if it experiences undue strain, and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection."
According to the report, the patent claim in question specifies: A first connector comprising: a first plurality of electrical contacts, the first plurality of electrical contacts to mate with a second plurality of electrical contacts when the first connector couples to a second connector, wherein the first plurality of electrical contacts consisting of a central contact to convey a signal, two contacts to convey a power supply, one contact on each side of the central contact, and two contacts to provide a return path, one contact on each side of the central contact, wherein when the first connector couples to the second connector, the first and second plurality of electrical contacts define a corresponding plurality of electrical paths; and a magnetic element, the magnetic element to mate with a plurality of magnets in the second connector that are proximally located and arranged in opposing polarities with respect to each other so that when the first connector is brought in close proximity to the second connector, magnetic field lines travel through the magnetic element of the first connector from one of the plurality of magnets in the second connector to another one of the plurality of magnets in the second connector.
