The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
Typically, coupling mechanisms for interfacing the electrical and lighting systems of towing vehicles and their respective towed vehicles require electrical power to be carried from the towing vehicle to the towed vehicle through a wire harness/cable. Most trailer lighting systems operate turn and brake signals. Thus, the electrical interface components that minimize wiring between towing mounts are helpful to interface the two electrical systems, which would otherwise be incompatible.
It is known in the art that the interconnections between vehicles often use threaded connectors that require tools to connect and disconnect. This also requires additional wiring. A gladhand type interconnection is often used with an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, or from a locomotive to railway air brakes on railroad cars. Such gladhand connectors resemble a pair of hands shaking when interlocked.
Other proposals have involved interconnecting electrical assemblies for towed vehicles. The problem with these tow connection assemblies is that they require tools and are time consuming to couple and decouple. Also, they require numerous wires. Even though the above cited tow connection assemblies meet some of the needs of the market, a gladhand electrical connectivity towing system that connects the electrical wiring from a towing vehicle to a towed vehicle by detachably coupling a pigtail to a vehicle mount through a tool-free, 20°-25° rotation gladhand connection of male and female gladhand couplers, and further aligning and stabilizing the electrical interfaces through the gladhand couplers, is still desired.
