Patent ID: 7704104

Claim:
A bus system for connecting a first wire lug to a second wire lug, the first wire lug having a first barrel end and an opposing first tang end defining a first stud hole and the second wire lug having a second barrel end and an opposing second tang end defining a second stud hole, the bus system comprising: an elongated shaft having a cross section and a desired length, wherein the shape and size of the cross section of the shaft are smaller than the shape and size of the first and second stud holes, so that the shaft is capable of passing through the first stud hole and the second stud hole such that the first lug and the second lug may be mounted onto the shaft with the shaft substantially perpendicular to the first and second tang ends; a conductive spacer having a desired thickness and defining a spacer hole, wherein the shape and size of the spacer hole are larger than the shape and size of the cross section of the shaft, so that the shaft is capable of passing through the spacer hole such that the spacer may be mounted onto the shaft with the shaft substantially perpendicular to the spacer and with the desired thickness of the spacer oriented along the length of the shaft; at least one locking mechanism having a locking surface, the locking mechanism adapted to engage the shaft at a desired location and to present the locking surface with an orientation substantially perpendicular to the shaft; and wherein the first wire lug, the second wire lug, and the spacer are capable of being mounted onto the shaft with the spacer interposed between and separating the first and second tang ends of the first and second wire lugs in sandwich fashion, with the shaft substantially perpendicular to the first and second tang ends, and the at least one locking mechanism may be engaged with the shaft such that the locking surface secures the wire lugs and spacer at a desired location and in electrical contact.
