  • Patent number: 11220188
    Abstract: A motor vehicle charging cable for DC voltage charging of an electrical energy store of a motor vehicle has a cable sheath that encloses conductors, such as first and second cooling-fluid-cooled electrical conductor for first and second DC voltage phases, a ground conductor or equipotential bonding conductor and/or at least one control conductor. Shaped elements are arranged between the cable sheath and the conductors at positions of the motor vehicle charging cable that are fixed in mounts. The shaped elements guide, clamp and restrict a relative movement between the conductors. The cable sheath restricts a relative movement between the conductors between those positions at which the motor vehicle charging cable is fixed in mounts.
