Abstract

An electrical connecting apparatus and related systems and methods are provided. The electrical connecting apparatus includes a substantially flat body having a top surface and a bottom surface. At least one electrically conductive tooth is positioned on the body, the at least one tooth having at least one puncture point positioned beyond at least one of the top and bottom surfaces, respectively. A coating is positioned on the at least one tooth. In use, when the electrical connecting apparatus is compressed, the at least one puncture point on the at least one tooth pierces through the coating thereon.

Claims

1. An electrical connecting apparatus comprising:

a substantially flat body having a top surface and a bottom surface;

at least two electrically conductive teeth positioned on and extending radially outwards from an exterior radial edge of the body, the at least two teeth each having at least one puncture point positioned beyond at least one of the top and bottom surfaces, respectively; and

a coating covering the at least two teeth, wherein the coating directly contacts an entirety of an exterior surface of each of the at least two teeth, and wherein the coating forms a webbing between the at least two teeth and directly in contact with the exterior radial edge of the body between the at least two teeth.

2. The electrical connecting apparatus of claim 1, wherein the body further comprises a clearance hole positioned therein, the clearance hole formed between the top and bottom surfaces.

3. The electrical connecting apparatus of claim 1, wherein the coating is positioned over an entirety of surfaces of the body.

4. The electrical connecting apparatus of claim 1, wherein the at least two teeth further comprise a plurality of teeth positioned on the exterior radial edge of the body and spaced around a circumference of the body, wherein the plurality of teeth extend radially outwards from the exterior radial edge.

5. The electrical connecting apparatus of claim 1, wherein the at least two teeth are biasable in a direction substantially perpendicular to a plane of at least one of the top and bottom surface of the body.

6. The electrical connecting apparatus of claim 1, wherein a thickness of the webbing on the exterior radial edge of the body between each of the at least two teeth is greater than a thickness of the coating on each of the at least two teeth.

7. The electrical connecting apparatus of claim 1, wherein each of the at least two teeth has at least two puncture points positioned on opposing sides thereof, wherein one of the at least two puncture points extends beyond a top surface of the body and another of the at least two puncture points extends beyond a bottom surface of the body.

8. The electrical connecting apparatus of claim 1, wherein the coating is positioned in direct contact with an entirety of the exterior radial edge of the body between the at least two teeth.

9. A system for providing an electrical connection comprising:

a first metal structure;

a second metal structure removably connected to the first metal structure with a fastener; and

an electrical connecting apparatus positioned between the first and second metal structures, the electrical connecting apparatus comprising;

a substantially flat body with a top surface and a bottom surface;

at least two electrically conductive teeth positioned on and extending radially outwards from an exterior radial edge of the body, the at least two teeth each having at least two puncture points positioned beyond the top and bottom surfaces, respectively, and in contact with the first and second metal structures, respectively; and

a coating covering an entirety of an exterior surface of each of the at least two teeth except the at least two puncture points, wherein the coating forms a webbing between the at least two teeth and directly in contact with the exterior radial edge of the body between the at least two teeth.

10. The system of claim 9, wherein the at least two teeth further comprises a plurality of teeth positioned on an exterior radial edge of the body and spaced around a circumference of the body, wherein the plurality of teeth extend radially outwards, and wherein the webbing is positioned between all of the plurality of teeth.

11. The system of claim 10, wherein a thickness of the webbing on the exterior radial edge of the body between each of the plurality of teeth is greater than a thickness of the coating on each of the plurality of teeth.

12. The system of claim 9, wherein the at least two puncture points are positioned on opposing sides of each tooth, wherein one of the at least two puncture points pierces the first metal structure and another of the at least two puncture points pierces the second metal structure.

13. The system of claim 12, wherein the coating seals a connection of the at least two puncture points to the first and second metal structures from exposure to an atmosphere.

14. An electrical connecting device comprising:

a serrated tooth star washer having a plurality of teeth positioned radially extending from a washer body; and

a coating positioned over an entirety of each of the plurality of teeth, wherein the coating forms a webbing extending between lateral sides of adjacent teeth of each of the plurality of teeth and directly in contact with an exterior radial edge of the washer body between each of the plurality of teeth, wherein when the serrated tooth star washer is compressed, at least one puncture point on each of the plurality of teeth pierces through the coating thereon.

15. The electrical connecting device of claim 14, wherein when the serrated tooth star washer is compressed, a portion of the webbing is displaced from between each of the plurality of teeth.
