摘要： Provided is a combination cable for a vehicle that is capable of reducing noise interference and cross-talk between twisted pair wires. The combination cable for a vehicle includes a wire bundle and a sheath covering the wire bundle. The wire bundle includes a two-core first twisted pair wire, a two-core second twisted pair wire, a one-core first wire, and a one-core second wire. When viewed in cable cross-section, the wire bundle has the first twisted pair wire disposed on one side of a center line that runs from a center of the first wire to a center of the second wire, and has the second twisted pair wire disposed on the other side of the center line, and the first twisted pair wire and the second twisted pair wire are separated from each other.

摘要： 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.
