Abstract

A spooling apparatus includes a spool for holding wire, the spool having a wire-retaining section and end plates, the end plates having one or more apertures. A conductive plate is positioned on an end plate of the spool opposite the wire-retaining section, and at least one conductive extension that extends through a corresponding aperture of the end plate such that the conductive extension is adjacent to the wire retaining section. Wire is spooled onto the wire-retaining section, at least a portion of the wire being uninsulated and in electrical contact with the conductive extensions of the conductive plate.

Claims

1. A spooling apparatus, comprising:

a spool for holding wire, the spool having a wire-retaining section and end plates;

a conductive plate positioned on an end plate of the spool opposite the wire-retaining section, and at least one conductive extension that extends through a corresponding aperture of the end plate such that the conductive extension is adjacent to the wire retaining section;

a wire spooled onto the wire-retaining section, at least a portion of the wire being uninsulated and in electrical contact with the conductive extensions of the conductive plate.

2. The spooling apparatus of claim 1, wherein the uninsulated portion is in electrical contact with the conductive extensions by wrapping the uninsulated portion around the spool.

3. The spooling apparatus of claim 1, wherein a section of the uninsulated portion extends through an aperture of the end plate and is in electrical contact with the conductive plate.

4. The spooling apparatus of claim 3, wherein the section of the uninsulated portion is positioned between the conductive plate and the end plate.

5. The spooling apparatus of claim 1, wherein the conductive plate comprises a connection point for connecting to an external voltmeter.

6. The spooling apparatus of claim 1, wherein the spool defines an axially extending, central aperture, and the conductive plate having an aperture aligned with the central axis of the spool, and further comprising a conductive attachment electrically connected to the conductive plate and extending through the central aperture and the central axis of the spool, the conductive attachment having a connection point for connecting to an external voltmeter.

7. The spooling apparatus of claim 6, further comprising a spool holder, the spool holder comprising a wire controlling portion that is positioned adjacent to at least one end plate of the spool.

8. The spooling apparatus of claim 7, wherein the conductive attachment is used to secure the spool to the spool holder.

9. The spooling apparatus of claim 7, wherein the spool holder comprises a flexible material shaped to have an inner cavity with an inner diameter that is substantially the same size as the diameter of the end plates of the spool.
