  • Patent number: 10377198
    Abstract: A gladhand electrical connectivity towing system couples electrical wiring from a towing vehicle to a towed vehicle through a quick and easy gladhand coupling operation between a pigtail and a vehicle mount. The system provides a pigtail that detachably couples to a vehicle mount through a tool-free, 20°-25° rotation, gladhand-type connection between male and female gladhand couplers. Two aligning gladhand couplers and one stabilizing gladhand coupler mate. The pigtail and vehicle mount include electrical interfaces that align and engage to conduct electricity from the towing vehicle to the towed vehicle. The electrical interfaces have lips and multiple apertures, with the lips forming a sealed interface to protect against moisture and debris. Multiple first conduction members are fitted into apertures in the electrical interfaces to conduct electricity from the power source of the towing vehicle to the towed vehicle.
