Keyed/anti-rotation grounding bus bar
First Claim
1. A motor vehicle comprising:
- a body/chassis; and
an electrical system, at least a portion of which is grounded to the body/chassis via a bus bar that comprises an electrically conductive metal plate having one or more threaded studs extending from an outer face of the plate, an electrically conductive spacer on an opposite face of the plate disposed against a surface of an electrically conductive part of the body/chassis to place the plate in electric continuity with the body/chassis part while spacing the plate from the surface of the body/chassis part, one or more fasteners holding the bus bar against the part, an array of through-slots in the plate surrounding each threaded stud, and an electrically conductive wire/cable terminating in an eyelet terminal comprising a generally flat annular contact area having a perimeter edge that includes a bent tab sized to lodge in any of the through-slots of the array surrounding one of the threaded studs, the terminal being in place on the one threaded stud with the tab lodged in a selected one of those through-slots to locate the terminal in a circumferential orientation about the one threaded stud correlated with the selected through-slot, and a nut tightened onto the one stud forcing the contact area of the terminal against an area of the outer face of the plate surrounding the one threaded stud.

Abstract
A bus bar (20) for grounding multiple wires/cables (74) in an engine compartment of a truck. The bus bar has four threaded studs (24, 26, 28, 30) extending from an outer face of a plate (22) and two circular rings (32, 34) on an opposite face spacing the plate from the dash panel (60). An array of multiple through-slots (24A, 26A, 28A, 30A) in the plate surround each threaded stud with the through-slots arranged in unique circumferential locations about the respective stud to provide unique circumferential locators for a tab (78) of an eyelet terminal (76) on a wire/cable (74) to locate the terminal in a correspondingly unique circumferential location about the threaded stud when placed thereon and in contact with the plate preparatory to tightening of a nut (80) that, when tightened, forcefully holds the terminal against the plate.
