The company says the upgraded assemblies help reduce the fatigue and strain on the plug and 7-way electrical cable experienced on some trailer applications where the electrical connection is higher than the air connections.
The trailer side lead on the 7-way electrical cable now extends out an additional 6 inches, and the spiral wrap on the same side is reduced by 6 inches, creating more slack on the 7-way cable. This change helps relieves strain placed on the cable lead and coupled 7-way electrical connection due to pull from the weight of the combination assembly experienced on some trailer applications, Phillips said.
With this improvement, the rubber air hoses now act as a shock absorber vs the electrical cable that should not be stretched or stressed, Phillips maintained. Also, the gladhand connections better support additional assembly pull-weight with a metal-to-metal connection. As an additional benefit, the extended length allows for more rotation in the lines during a severe jack-knife.
Phillips’ 3-in-1 and 4-in-1 combination assemblies with QCP or STA-DRY QCMS2/QCP 7-way electrical connectors are designed to provide an all-in-one electrical and air system for cable protection and corrosion prevention.
