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:

a first pair of positive magnetic couplers connected by a first insulated elongate electrical conductor; and

a second pair of negative magnetic couplers connected by a second insulated elongate electrical conductor, the first and second insulated elongate electrical conductors being at least partially co-extensive,

wherein each of the magnetic couplers includes a magnetic element partially surrounded by insulative material, and wherein each of the magnetic elements is oriented in a same magnetic orientation in the insulative material, and

wherein a single surface of each of the magnetic elements is flush with a first side of the insulative material, and wherein a second surface of each of the magnetic elements is recessed from but open to a second opposite side of the insulative material.

2. 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 conductors, 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 a corresponding elongate, insulated, electrically-isolated electric conductor,

a north magnetic pole and a south magnetic pole of the magnetic element are each oriented toward opposing sides of the individual magnetic coupler, and

one of the opposing sides of the individual magnetic coupler defines an indentation in the insulative material, the indentation extending to the magnetic element.
