Magnetically connected universal computer power adapter
A magnetically connected universal computer power adapter is presented. The computer power adapter provides a power supply, a power cord, a cord connector, and a charging plug. The cord connector and charging plug each contain a magnet that magnetically couple the cord connector to the charging plug. The cord connector may couple with more than one type of charging plug, allowing the universal computer power adapter to be used with many different computer models.
1. A power adapter, comprising:
a) a power supply that supplies power over a power cord, the power cord including an integrated cord connector having
i) a cord connector face that presents at least two cord connection points that carry the DC power; and
ii) a cord connector magnet; and
b) a connection plug having:
i) a plug connection face having at least two plug connection points, the plug connection points positioned on the plug connection face so at to contact the at least two cord connection points when the plug connection face is in contact with the cord connector face,
ii) a tip electrically connected to the plug connection points and configured to interface with a power socket of a computer, and
iii) a connection plug magnet positioned to attract the cord connector magnet when the plug connection face is in contact with the cord connector face.
2. The power adapter of claim 1 , wherein the cord connector magnet and the connection plug magnet are rare earth magnets.
3. The power adapter of claim 1 , wherein the cord connection points and the plug connection points are non-magnetic electrical conductors.
4. The power adapter of claim 1 , wherein the cord connector face is a surface of a cord connector body, further wherein the cord connector body contains at least one spring attached to at least one of the cord connection points to allow movement of the connected cord connection point relative to the cord connector body.
5. The power adapter of claim 4 , wherein the spring is secured to a base plate running behind the cord connection points.
6. The power adapter of claim 5 , wherein the cord connector magnet comprises the base plate.
7. The power adapter of claim 1 , wherein the plug connection face is a surface of a connection plug body, further wherein the connection plug body contains at least one spring attached to at least one of the plug connection points to allow movement of the connected plug connection point relative to the connection plug body.
8. A method of charging an electrical device, comprising:
a) inserting a tip of a connection plug, which includes a plug connection face, into a power socket of the electrical device;
b) positioning the plug connection face proximate to a cord connection face that is one piece with a power cord;
c) aligning plug connection points in the plug connection face, which are electrically connected to the tip, with cord connection points in the cord connection face, wherein the plug connection face and the cord connection face each contain a magnet, the two magnets being of opposite polarity;
d) holding the plug connection points in contact with corresponding cord connection points by magnetic attraction between the magnets; and
e) supplying power to the power socket of the electrical device through the power cord, the cord connection points, the plug connection points, and the tip.
