Phillips Industries has announced all 3-IN-1 and 4-IN-1 electrical and air combination assemblies with a QCP trailer side connection have been redesigned as an added benefit to relieve strain placed on the cable lead and coupled trailer 7-way electrical connection due to pull from the weight of the combination assembly on certain trailer applications.
As a solution to reduce fatigue and strain on the plug and cable, the trailer side lead on the 7-way electrical cable is being extended out an additional 6 in. and the spiral wrap on this same side is being reduced 6 in. By doing so it creates more slack on the 7-way cable, the company says.
The gladhand connections, which are a solid mechanical means, will now better aid in the support of additional assembly pull weight with a metal-to-metal connection (coupling plates). Additionally, the rubber air hoses act as a shock absorber versus the electrical cable that shouldn’t be stretched or stressed. This revision also allows for more rotation in the lines during a severe jack-knife, Phillips says.
