Abstract

A quick disconnect power adapter for maintaining a connection between a plug and a receptacle. In various embodiments, the quick disconnect power adapter maintains a completed circuit for providing power from a power source to an electrical device with a releasable fastener. In particular embodiments, the releasable fastener includes one or more magnets. In various embodiments, the quick disconnect power adapter is configured such that the electrical contact points of the plug and receptacle cannot be touched or otherwise contacted by a user when the plug and receptacle are not engaged.

Claims

1. An adapter for use in maintaining an electrical connection between an electrical device and an electrical outlet, said adapter being adapted to facilitate a safe break in said electrical connection, wherein said adapter comprises:

a first connector that comprises a first set of one or more electrical contacts, said first set of one or more electrical contacts comprising a first live contact, a first neutral contact, and a first ground contact;

a second connector that comprises a second set of one or more electrical contacts, said second set of one or more electrical contacts comprising a second live contact, a second neutral contact, and a second ground contact;

a releasable fastener that is adapted to form a releasable connection between said first connector and said second connector, and

a switch that is adapted to selectively, while said releasable fastener forms a releasable connection between said first connector and said second connector and said first ground contact is in electrical communication with said second ground contact;

(A) move said first live contact into electrical communication with said second live contact and (B) move said first neutral contact into electrical communication with said second neutral contact, wherein;

said releasable fastener is adapted so that an application of a sufficient force pulling said first connector away from said second connector releases said connection between said first and second connectors so that said first set of electrical contacts disengages from said second set of electrical contacts.

2. The adapter of claim 1, wherein said adapter is configured so that a human finger cannot contact at least one of said second set of electrical contacts.

3. The adapter of claim 2, wherein said second set of electrical contacts is recessed into said second connector so that at least a particular one of said second set of electrical contacts is only accessible through a passageway that is sufficiently small to prevent a human finger from extending through said passageway and touching said particular electrical contact.

4. The adapter of claim 1, wherein said first connector is not adapted to form an operative electrical connection with a connector other than said second connector while said releasable fastener forms said releasable connection between said first connector and said second connector.

5. The adapter of claim 1, wherein:

said first connector comprises a lip that extends outwardly around at least a portion of a perimeter of a distal face of said first connector; and

said lip is adapted to overlap at least a portion of a lateral exterior surface of said second connector when said releasable fastener forms said releasable connection between said first connector and said second connector.

6. The adapter of claim 1, wherein said first connector is a plug-side connector that is connected directly to an electronic device.

7. The adapter of claim 1, wherein said first connector is a plug-side connector that is connected to a power cord of an electronic device.

8. An adapter for use in maintaining an electrical connection between an electrical device and an electrical outlet, said adapter being adapted to facilitate a safe break in said electrical connection, wherein said adapter comprises:

a first connector that comprises a first set of one or more electrical contacts, said first set of one or more electrical contacts comprising a first live contact, a first neutral contact, and a first ground contact;

a second connector that comprises a second set of one or more electrical contacts, said second set of one or more electrical contacts comprising a second live contact, a second neutral contact, and a second ground contact; and

a releasable fastener that is adapted to form a releasable connection between said first connector and said second connector, wherein

said first and second sets of electrical contacts are positioned so that, as said first connector and said second connector are moved towards each other so that said releasable fastener forms said releasable connection between said first connector and said second connector;

(A) said first ground contact makes contact with said second ground contact;

and (B) after said first ground contact makes contact with said second ground contact;

(1) said first live contact makes contact with said second live contact, and (2) said first neutral contact makes contact with said second neutral contact, and

said releasable fastener is adapted so that an application of a sufficient force pulling said first connector away from said second connector releases said connection between said first and second connectors so that said first set of electrical contacts disengages from said second set of electrical contacts.

9. The adapter of claim 8, wherein said adapter is configured so that a human finger cannot contact at least one of said second set of electrical contacts.

10. The adapter of claim 9, wherein said second set of electrical contacts is recessed into said second connector so that at least a particular one of said second set of electrical contacts is only accessible through a passageway that is sufficiently small to prevent a human finger from extending through said passageway and touching said particular electrical contact.

11. The adapter of claim 8, wherein said first connector is not adapted to form an operative electrical connection with a connector other than said second connector while said releasable fastener forms said releasable connection between said first connector and said second connector.

12. The adapter of claim 8, wherein:

said first connector comprises a lip that extends outwardly around at least a portion of a perimeter of a distal face of said first connector; and

said lip is adapted to overlap at least a portion of a lateral exterior surface of said second connector when said releasable fastener forms said releasable connection between said first connector and said second connector.

13. The adapter of claim 8, wherein said first connector is a plug-side connector that is connected directly to an electronic device.

14. The adapter of claim 8, wherein said first connector is a plug-side connector that is connected to a power cord of an electronic device.
