Benefits of technology

[0006]An advantage of the invention is that it is easier to use than prior art devices and adheres more securely to most types of terminals. The magnets do not stick to brass but adhere very well to steel. Approximately eighty percent of terminals today have steel screws.
[0007]Another advantage of the invention is that it works just as well with recessed terminals as with exposed terminals.

Problems solved by technology

This lead also cannot be used with recessed terminals.
No jumpers having magnets at both ends are known to exist in the prior art, and no prior art jumpers suitable for use with recessed terminals are known to exist.

Embodiment Construction

[0013]The magnetic jumper comprises a wire 4 having a magnet 2 at each end. A neodymium magnet 2 is pressed into a brass barrel 1 that is crimped over a single conductor multi-strand wire 4 that has a copper conductor 5 folded over within the wire 4. A magnet 2 is attached in this manner at each end of the wire 4. A means 3 for non-conduction of electricity is provided at each end of the wire 4. The non-conductive means 3 can be any of several alternatives. The non-conductive means 3 can be a molded end of vinyl, silicon, or other non-conductive material, which can be made by injection molding. Alternatively, the non-conductive means 3 can be a heat-shrink tube fitted over the brass barrel 1 at each end of the wire 4, leaving the magnet 2 exposed. In still another alternative, the non-conductive means 3 can be a dipped vinyl coating or other non-conductive coating at each end of the wire 4, the coating covering the barrel 1 and a part of the wire 4 that extends from the barrel 1 at ...

Abstract

A magnetic jumper for bypassing electrical circuits. The jumper includes a magnet at each end of a wire. Each magnet can be attached to a terminal of a low voltage electrical circuit in order to bypass that circuit for testing and troubleshooting purposes. The magnetic jumper works with almost any terminal that has steel screws.

Description

[0001]This application claims the benefit of Provisional Patent Application No. 61 / 341,339, filed Mar. 30, 2010, which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]Alligator clip jumpers are used today to clip onto terminals in order to bypass electrical circuits for testing and troubleshooting purposes. Alligator clips have several disadvantages. They pop off easily and cannot be clipped onto recessed terminals as are found on thermostat sub-bases, for example.[0003]Also known in the prior art is a test lead for a meter, the test lead having only one magnetic end, in a flush configuration. This lead also cannot be used with recessed terminals.[0004]No jumpers having magnets at both ends are known to exist in the prior art, and no prior art jumpers suitable for use with recessed terminals are known to exist.SUMMARY OF THE INVENTION[0005]The invention is a magnetic jumper for bypassing electrical circuits. The magnetic jumper is used to test electrical circuit...
