Abstract

A power cord assembly includes first and second cable units. The first cable unit includes a first cable having first and second ends, a device connector disposed on the first end of the first cable and adapted to be coupled to a power port of an electrical device, and a first connector disposed on the second end of the first cable. The second cable unit includes a second cable having first and second ends, a power plug disposed on the first end of the second cable and adapted to be coupled to a power outlet, and a second connector disposed on the second end of the second cable. The first and second connectors are coupled electrically, magnetically, and releasably to each other.

Claims

1. A power cord assembly comprising:

a first cable unit including a first cable having first and second ends, a device connector disposed on said first end of said first cable and adapted to be coupled to a power port of an electrical device, and a first connector disposed on said second end of said first cable; and

a second cable unit including a second cable having first and second ends, a power plug disposed on said first end of said second cable and adapted to be coupled to a power outlet, and a second connector disposed on said second end of said second cable;

wherein said first and second connectors are coupled electrically, magnetically, and releasably to each other.

2. The power cord assembly as claimed in claim 1, further comprising a power supply unit disposed on one of said first cable and said second cable, said power supply unit being adapted to convert a voltage supplied through said power plug from the power outlet to a different voltage.

3. The power cord assembly as claimed in claim 1, wherein:

said first connector includes a first housing having a first contact surface and which is formed with a cavity extending inwardly from said first contact surface, and a plurality of first contacts disposed in said cavity and electrically coupled to said first cable;

said second connector includes a second housing having a second contact surface, a protrusion extending outwardly from said second contact surface and which is formed with a plurality of holes, and a plurality of second contacts disposed respectively in said holes and electrically coupled to said second cable; and

when said first and second connectors are coupled to each other, said first and second contact surfaces are magnetically attracted to each other, said protrusion is inserted into said cavity, and said first contacts are inserted respectively into said holes to contact said second contacts.

4. The power cord assembly as claimed in claim 3, further comprising a magnet disposed on one of said first contact surface and said second contact surface, and a metal plate disposed on the other of said first contact surface and said second contact surface, said magnet and said metal plate being magnetically attracted to each other when said first and second connectors are coupled to each other.
