Abstract

A busbar is provided for attaching a conductor to a support structure. The busbar can include a main bonding wall, a first mounting wall extending away from a first end of the main bonding wall, a second mounting wall extending away from a second end of the main bonding wall. A first flap can extend at an angle from the first mounting wall towards the second mounting wall and the main bonding wall, or a second flap can extend at an angle from the second mounting wall towards the first mounting wall and the main bonding wall.

First claim

The invention claimed is:

1. A busbar for use with a first hose clamp of a first size and a second hose clamp of a second, different size, for selectively attaching a conductor to a first round support structure of a first diameter, a second round support structure of a second diameter different from the first diameter, and a flat support structure, the busbar comprising:
a main bonding wall having a first end and a second end;
a first mounting wall extending away from the first end of the main bonding wall;
a second mounting wall extending away from the second end of the main bonding wall;
a first flap extending at an angle from the first mounting wall towards the second mounting wall and the main bonding wall;
a second flap extending at an angle from the second mounting wall towards the first mounting wall and the main bonding wall; and
first and second sets of slots, with a first slot of each of the first and second sets of slots extending through the first flap and a second slot of each of the first and second sets of slots extending through the second flap;
wherein the first and second slots of the first set of slots are disposed between the first and second slots of the second set of slots and are configured to receive the first hose clamp to secure the busbar to the first round support structure; and
wherein the first and second slots of the second set of slots are configured to receive the second hose clamp to secure the busbar to the second round support structure.

2. The busbar of claim 1 , wherein the first flap extends away from the first mounting wall at an angle of between 60° and 90.

3. The busbar of claim 2 , wherein the second flap extends away from the second mounting wall at an angle of between 60° and 90°.

4. The busbar of claim 3 , wherein the first flap extends away from first mounting wall at an angle of 80° and the second flap extends away from the second mounting wall at an angle of 80°.

5. The busbar of Claim 1 , wherein first mounting holes extend through at least one of the first mounting wall or the main bonding wall, the first mounting holes being configured to selectively receive a first double-hole bonding lug with the first double-hole bonding lug in at least two different orientations.

6. The busbar of claim 5 , wherein second mounting holes extend through the second mounting wall, the second mounting holes being configured to selectively receive a second double-hole bonding lug with the second double-hole bonding lug in at least two different orientations.

7. The busbar of claim 5 , wherein one or more second mounting holes extend through the first mounting wall, the one or more second mounting holes being configured to receive a plurality of beam clamp assemblies independently of the first mounting holes.

8. The busbar of claim 5 , wherein the first mounting holes include at least four mounting holes arranged in a diamond pattern.

9. The busbar of claim 1 , wherein the main bonding wall, the first mounting wall, and the second mounting wall collectively at least partly define a recess; and
wherein the first flap and the second flap extend separately across a portion of the recess to define a gap between a distal end of the first flap and a distal end of the second flap.

10. The busbar of claim 1 , wherein the first and second mounting walls extend, respectively, from the first and second ends of the main bonding wall at an angle of 90°.

11. The busbar of claim 1 , wherein the busbar is formed of copper.

12. The busbar of claim 11 , wherein the busbar includes a tin coating.

13. A busbar for selective attachment to a first round support structure of a first diameter, a second round support structure of a second diameter different from the first diameter, and a flat support structure, in order to selectively secure bonding connections relative to the first round support structure, the second round support structure, or the flat support structure, the busbar comprising:
a single-piece body including:
a base wall;
first and second side walls extending from opposite ends of the base wall;
a first flap extending at a first acute angle from the first side wall opposite the base wall; and
a second flap extending at a second acute angle from the second side wall opposite the base wall;

each of the first and second flaps including one or more sets of round-structure mounting openings;
at least one of the base wall, the first side wall, or the second side wall including one or more sets of flat-structure mounting openings; and
at least one of the base wall, the first side wall, or the second side wall including one or more sets of bonding openings configured to secure one or more of the bonding connections to the busbar;
the one or more sets of round-structure mounting openings being configured to receive one or more hose clamps to selectively secure the busbar to the first round support structure and the second round support structure, with the first and second flaps urged into engagement with the first round support structure and the second round support structure, respectively; and
the one or more sets of flat-structure mounting openings being configured to receive one or more clamp assemblies to selectively secure the busbar to the flat support structure.

14. The busbar of claim 13 , for use with a first hose clamp of a first size and a second hose clamp of a second, different size, wherein the one or more sets of round-structure mounting openings include first and second sets of slots, with a first slot of each of the first and second sets of slots extending through the first flap and a second slot of each of the first and second sets of slots extending through the second flap;
wherein the first and second slots of the first set of slots are disposed between the first and second slots of the second set of slots and are configured to receive the first hose clamp to secure the busbar to the first round support structure; and
wherein the first and second slots of the second set of slots are configured to receive the second hose clamp to secure the busbar to the second round support structure.

15. The busbar of claim 13 , wherein the one or more sets of bonding openings include at least four mounting holes configured to selectively receive a first double-hole bonding lug with the first double-hole bonding lug in at least two different orientations.

16. The busbar of claim 13 , wherein the first flap extends away from the first side wall at a first angle of greater than 60°; and
wherein the second flap extends away from the second side wall at a second angle of greater than 60°.

17. The busbar of claim 16 , wherein the first angle is substantially equal to the second angle.

18. The busbar of claim 16 , wherein the first and second flaps extend towards each other to define a gap between distal ends of the first and second flaps.

19. A method of manufacturing a busbar that is configured to be selective attached to a first round support structure of a first diameter, a second round support structure of a second diameter different from the first diameter, and a flat support structure, in order to selectively secure bonding connections relative to the first round support structure, the second round support structure, or the flat support structure, the method comprising:
providing a single-piece copper blank; and
stamping the single-piece copper blank to form:
a plurality of mounting openings and a plurality of bonding openings;
a first wall that includes a first set of the plurality of bondi
