Abstract

This patent pertains to magnetic coupling systems. One implementation includes magnetic jumper cables, which include magnetic couplers and elongate, insulated, electrically-isolated electric conductors.

Claims

1. A set of magnetic jumper cables, comprising:

two lengths of elongate, insulated, electrically-isolated electric conductors; and

magnetic couplers configured in electrical connection with at least one end of each of the two lengths of elongate, insulated, electric conductor, wherein an individual magnetic coupler includes;

an insulative material, and

a magnetic element,

wherein the magnetic element is positioned within the insulative material such that the magnetic element is in electrical connection with the elongate, insulated, electrically-isolated electric conductor,

further wherein north magnetic poles of each of the magnetic elements of the magnetic couplers are exposed at a first surface of the insulative material, and

further wherein south magnetic poles of each of the magnetic elements of the magnetic couplers are not covered by the insulative material but are indented back from an opposing second surface of the insulative material.

2. The set of magnetic jumper cables of claim 1, wherein the magnetic couplers define a hole extending from the first surface through the magnetic elements to the opposing second surface.

3. A set of magnetic jumper cables, comprising:

two lengths of elongate, insulated, electrically-isolated electric conductors; and

magnetic couplers configured in electrical connection with at least one end of each of the two lengths of elongate, insulated, electric conductor, wherein an individual magnetic coupler includes;

an insulative material, and

a magnetic element,

wherein the magnetic element is positioned within the insulative material such that the magnetic element is in electrical connection with the elongate, insulated, electrically-isolated electric conductor,

further wherein south magnetic poles of each of the magnetic elements of the magnetic couplers are exposed at a first surface of the insulative material, and

further wherein north magnetic poles of each of the magnetic elements of the magnetic couplers are not covered by the insulative material but are indented back from an opposing second surface of the insulative material.

4. The set of magnetic jumper cables of claim 3, wherein the magnetic couplers define a hole extending from the first surface through the magnetic elements to the opposing second surface.

5. A set of magnetic jumper cables, comprising:

two lengths of elongate, insulated, electrically-isolated electric conductors extending between a first end and a second end; and

two magnetic couplers configured in electrical connection with the two lengths at the first end, wherein an individual magnetic coupler includes;

an insulative material, and

a magnetic element positioned within the insulative material where;

the magnetic element is in electrical connection with one of the two lengths at the first end,

a north magnetic pole of the magnetic element is exposed at a first surface of the insulative material, and

a south magnetic pole of the magnetic element is not covered by the insulative material and is indented back from an opposing second surface of the insulative material.

6. The set of magnetic jumper cables of claim 5, wherein the individual magnetic coupler defines a hole extending from the first surface through the magnetic element to the opposing second surface.

7. The set of magnetic jumper cables of claim 5, wherein the second end is connected to a battery charger.

8. A set of magnetic jumper cables, comprising:

two lengths of elongate, insulated, electrically-isolated electric conductors extending between a first end and a second end; and

two magnetic couplers configured in electrical connection with the two lengths at the first end, wherein an individual magnetic coupler includes;

an insulative material, and

a magnetic element positioned within the insulative material where;

the magnetic element is in electrical connection with one of the two lengths at the first end,

a south magnetic pole of the magnetic element is exposed at a first surface of the insulative material, and

a north magnetic pole of the magnetic element is not covered by the insulative material and is indented back from an opposing second surface of the insulative material.

9. The set of magnetic jumper cables of claim 8, wherein the individual magnetic coupler defines a hole extending from the first surface through the magnetic element to the opposing second surface.

10. The set of magnetic jumper cables of claim 8, wherein the second end is connected to a battery charger.
