Abstract

An assembly can include a housing that includes opposing ends, a longitudinal axis, an axial length defined between the opposing ends, a maximum transverse dimension that is less than the length and an interior space; circuitry disposed at least in part in the interior space; and a coated electrical conductor electrically coupled to the circuitry where the coated electrical conductor includes an electrical conductor that includes copper and a length defined by opposing ends, a polymeric electrical insulation layer disposed about at least a portion of the length of the electrical conductor, and a barrier layer disposed about at least a portion of the polymeric electrical insulation layer.

First claim

What is claimed is:

1. An assembly comprising:
a housing that comprises opposing ends, a longitudinal axis, an axial length defined between the opposing ends, a maximum transverse dimension that is less than the length and an interior space;
circuitry disposed at least in part in the interior space; and
a coated electrical conductor electrically coupled to the circuitry wherein the coated electrical conductor comprises an electrical conductor that comprises copper and a length defined by opposing ends, a polymeric electrical insulation layer disposed about at least a portion of the length of the electrical conductor, and a barrier layer disposed about at least a portion of the polymeric electrical insulation layer,
wherein the barrier layer comprises a sol-gel layer.

2. The assembly of claim 1 wherein the circuitry comprises sensor circuitry of a sensor operatively coupled to the housing.

3. The assembly of claim 1 wherein the circuitry comprises electric motor circuitry of an electric motor operatively coupled to the housing.

4. The assembly of claim 1 wherein the coated electrical conductor is a magnet wire that forms part of an electrical-mechanical component.

5. The assembly of claim 1 wherein the barrier layer comprises a metallic barrier layer.

6. The assembly of claim 5 wherein the metallic barrier layer comprises nickel.

7. The assembly of claim 1 wherein the barrier layer comprises poly(p-xylylene).

8. The assembly of claim 1 wherein the polymeric electrical insulation layer comprises polyimide.

9. The assembly of claim 1 wherein the barrier layer comprises a thickness greater than approximately 10 microns and less than approximately 50 microns.

10. The assembly of claim 1 wherein the electrical conductor comprises a diameter greater than 28 AWG and less than 1 AWG.

11. The assembly of claim 1 wherein the barrier layer comprises tape.

12. The assembly of claim 1 wherein the barrier layer comprises vapor deposited barrier layer.

13. An assembly comprising:
a housing that comprises opposing ends, a longitudinal axis, an axial length defined between the opposing ends, a maximum transverse dimension that is less than the length and an interior space;
circuitry disposed at least in part in the interior space;
a coated electrical conductor electrically coupled to the circuitry wherein the coated electrical conductor comprises an electrical conductor that comprises copper and a length defined by opposing ends, a polymeric electrical insulation layer disposed about at least a portion of the length of the electrical conductor, and a barrier layer disposed about at least a portion of the polymeric electrical insulation layer; and
a scavenger material disposed in at least one layer of the coated electrical conductor wherein the scavenger material comprises a water scavenger material, a H 2 S scavenger material or a water scavenger material and a H 2 S scavenger material.

14. The assembly of claim 13 wherein the scavenger material comprises aluminum, lead (Pb), molybdenum or a combination of two or more of aluminum, lead (Pb) and molybdenum.
