  • Patent number: 10978223
    Abstract: A ground termination system may include a backshell for an electrical connector, a grounding insert and a ferrule. The grounding insert includes an outer peripheral edge and a centrally disposed aperture. The outer peripheral edge may be sized to fixedly engage a surrounding portion of the backshell and the centrally disposed aperture may be defined by a plurality of lobes. A first group of the lobes may be sized to receive power conductors of a variable frequency drive power cable. The ferrule may include a crimp barrel and a sleeve. The crimp barrel may receive a ground conductor and be rigidly clamped thereto. The sleeve of the ferrule may fixedly engage one of the lobes in the second group of lobes and anchor the ferrule in the aperture.
