Abstract

A bonding stud for a data center cabinet comprises a body adapted to geometrically conform to a cage nut hole within the cabinet. The body may comprise opposing threaded studs and an annular shoulder that extends outward from the body to provide contact and bonding with ground strips used in connection with the data center cabinet. Projections formed between the shoulder and the sides of the body may penetrate the surface of the frame rails of the data center cabinet to provide a bond to the base metal of the frame rails.

Claims

1. A bonding stud comprising:

a body having a first threaded stud extending from a first surface of the body and a second threaded stud extending from a second surface of the body, wherein the body has a square-shaped cross-section;

the body further having a stop surface extending outwardly from the body and at least one projection, the at least one projection includes a first surface in contact with the body and a second surface in contact with the stop surface.

2. The bonding stud of claim 1, wherein the body is dimensioned to geometrically conform to a cage nut hole within a data center cabinet.

3. The bonding stud of claim 1, wherein the stop surface is an annular shoulder.

4. The bonding stud of claim 3, wherein the annular shoulder has an annular rib extending from the annular shoulder.

5. The bonding stud of claim 1, wherein the at least one projection is positioned between the first and second threaded studs.

6. The bonding stud of claim 1, wherein the body has four sides and each side includes between one and three projections.

7. The bonding stud of claim 1, wherein the at least one projection comprises between four and twelve projections.

8. The bonding stud of claim 1, wherein the at least one projection comprises a tooth having a cutting surface.

9. The bonding stud of claim 1, wherein the at least one projection has a triangular-shaped cross-section.
