Grounding spacer
A grounding spacer is provided. The grounding spacer comprising a circular body having a top surface, a bottom surface, and a central aperture, and a plurality of radially spaced penetration features, wherein at least one of the penetration features has at least a portion thereof extending from the top surface, and wherein at least one of the penetration features has at least a portion thereof extending from the bottom surface.
1. A method of manufacturing a grounding spacer comprising:
first stamping a flat piece of sheet metal to form a flat blank grounding spacer having a circular shape, a central aperture, and a plurality of elliptical apertures including first and second arcs;
second stamping the flat blank grounding spacer to form a plurality of upstanding rims about at least some of the plurality of apertures in a first direction; and
third stamping the blank to form depending rims about at least some of the plurality of apertures in a second direction,
wherein the second and third stampings form an upstanding rim portion and a depending rim portion along each of the plurality of apertures, and wherein the upstanding and depending rim portions are separated.
2. The method of claim 1 , wherein the plurality of apertures of the flat blank grounding spacer are elongate.
3. The method of claim 1 , wherein the second and third stampings form rims alternatingly extending in opposite directions.
4. The method of claim 1 , wherein the upstanding and depending rim portions are side by side around an aperture.
5. The method of claim 1 , wherein the upstanding and depending rim portions are separated by an inner and outer arcs.
6. The method of claim 1 , wherein the plurality of apertures are positioned around the central aperture.
7. The method of claim 1 , wherein the plurality of apertures are peripherally positioned around the central aperture.
8. The method of claim 1 , wherein the plurality of apertures are concentrically positioned about the central aperture.
9. The method of claim 1 , wherein the grounding spacer comprises a grounding washer.
