BUSBAR BRIDGE AND ASSEMBLY

1 . A busbar bridge for electrically connecting a busbar to an electrical terminal, comprising:

an electrically conductive plate shaped to form a six-sided cage adapted to receive a nut; and

a nut disposed in the cage and having flat sides corresponding with and located in close proximity to the sides of the cage such that translational and rotational movement of the nut is prevented when torque is applied to a bolt engaging threads of the nut.

2 . The busbar bridge of claim 1 , wherein the nut is a square nut.

3 . The busbar bridge of claim 1 , that is formed of copper.

4 . The busbar bridge of claim 1 , wherein the nut is formed of steel.

5 . The busbar bridge of claim 4 , wherein the nut can withstand a torque of 50 Nm.

6 . The busbar bridge of claim 1 , wherein the cage is sized to allow about 1 mm of movement of the nut with respect to the cage along each of three mutually perpendicular axes.

7 . A busbar bridge and busbar assembly for electrically connecting a first electrical terminal with a second electrical terminal, comprising:

the busbar bridge of claim 1 ;

a busbar having a first bolt aperture at a first end for connecting with the first electrical terminal and a second bolt aperture at a second end; and

a bolt connecting the second end of the busbar with the busbar bridge.

8 . The assembly of claim 7 , wherein the nut is a square nut.

9 . The assembly of claim 7 , that is formed of copper.

10 . The assembly of claim 7 , wherein the nut is formed of steel.

11 . The assembly of claim 7 , wherein the nut can withstand a torque of 50 Nm.

12 . The assembly of claim 7 , wherein the cage is sized to allow about 1 mm of movement of the nut with respect to the cage along each of three mutually perpendicular axes.

13 . The assembly of claim 7 , wherein the bolt has a flanged head.

14 . The assembly of claim 7 , wherein the bolt has self-connecting radiused threads.

15 . The assembly of claim 7 , wherein the busbar has a U-shaped flexing section.
