Abstract

In one embodiment, the present invention is a power adapter for coupling electrical power from a standard North Atlantic Treaty Organization (NATO) power coupling to one or more electronic devices. In one embodiment, the power adapter includes a plug connector adapted for receiving electrical power from the power coupling, a receptacle adapted for providing the electrical power to a slave cable (e.g., an inter-vehicular slave cable), and at least one terminal adapted for providing the electrical power to the electronic devices (e.g., a computer system). The power adapter is thus capable of maximizing the potential of the power coupling to provide electrical power for multiple simultaneous uses.

Claims

1. An apparatus for coupling electrical power from a standard North Atlantic Treaty Organization (NATO) power coupling to one or more electronic devices, the apparatus comprising:

a plug connector adapted for receiving said electrical power from said NATO power coupling;

a receptacle adapted for providing said electrical power to a slave cable;

at least one terminal adapted for providing said electrical power to said one or more electronic devices;

a center pin connecting a positive terminal of said plug connector to a positive terminal of said receptacle;

a negative male; and

a negative female mated with said negative male such that a mated pair comprising said negative female and said negative male connects a negative terminal of said plug connector to a negative terminal of said receptacle.

2. The apparatus of claim 1, wherein said NATO power coupling is of a type used in military vehicles.

3. The apparatus of claim 1, wherein said NATO power coupling is of the type defined by NATO standardization agreement 4074.

4. The apparatus of claim 1, wherein said at least one terminal comprises an electrical connection connected to a binding post.

5. The apparatus of claim 1, wherein said center pin is nested within said mated pair.

6. The apparatus of claim 1, wherein at least one of:

said center pin, said negative male, or said negative female is constructed from one or more materials that comply with NATO standardization agreement 4074 as of Feb. 7, 2006.

7. The apparatus of claim 1, wherein said center pin connects said positive terminal of said plug connector to said positive terminal of said receptacle with assistance from mediating circuitry.

8. The apparatus of claim 7, wherein said mediating circuitry comprises at least one of:

a fuse, a circuit breaker, a surge protector, a switch, a light-emitting diode, or a transformer.

9. The apparatus of claim 7, wherein said mediating circuitry is rated such that connection of said one or more electrical devices to said at least one terminal is protected from connection of said slave cable to said plug connector.

10. The apparatus of claim 7, wherein said at least one terminal comprises at least two pairs of terminals, said mediating circuitry being shared by said at least two pairs of terminals.

11. The apparatus of claim 7, wherein said at least one terminal comprises at least two pairs of terminals, each of said at least two pairs of terminals utilizing different mediating circuitry.

12. The apparatus of claim 1, wherein said mated pair connects said negative terminal of said plug connector to said negative terminal of said receptacle with assistance from mediating circuitry.

13. The apparatus of claim 12, wherein said mediating circuitry comprises at least one of:

a fuse, a circuit breaker, a surge protector, a switch, a light-emitting diode, or a transformer.

14. The apparatus of claim 1, further comprising:

a dielectric male positioned between said center pin and said negative male; and

a dielectric female positioned between said center pin and said negative female.

15. The apparatus of claim 14, wherein said dielectric male and said dielectric female are each formed of an electrically non-conducting material.
