Abstract
A data communications coupler is provided for communicating data related to various operating conditions of a tractor and/or a trailer. The data communications coupler preferably includes a first coupler portion arranged to connect to a tractor. The first coupler portion has a first lens positioned therein for allowing data communications signals to pass therethrough. A second coupler portion is arranged to connect to a trailer and to connect to the first coupler portion. The second coupler portion has a second lens positioned therein for allowing data communication signals to pass therethrough. A data communicator is positioned in the first and second coupler portions for communicating data between the first and second coupler portions through the first and second lenses. Each of the first and second lenses preferably has a body integrally formed of a translucent material for allowing light to pass therethrough. The body includes an enclosed distal end portion for abuttingly contacting and interfacing with a distal opening of a coupler and a base integrally connected to the distal end portion and arranged for positioning means for data communications therein.
