Magnetic circuits for communicating data in a tractor and trailer combination. In a preferred embodiment, a connector for interfacing electrical signals between a tractor and trailer which will be connected together such that the tractor pulls the trailer comprises a receptacle interfaced between the tractor/trailer for housing first electrical interface members that carry electrical signals output from the tractor to the trailer and receiving electrical signals output from the trailer to the tractor, a plug connectable to the receptacle for housing second interface members that carry electrical signals output from the trailer to the tractor, and receiving electrical signals output from the tractor to the trailer, a first coil in the receptacle for communicating data from data-producing devices in the tractor to data-receiving devices in the trailer, and for receiving data from the data-producing devices in the trailer, and a second coil in the plug for receiving the data. The magnetic circuits described herein provide efficient and clean electrical signals for digital data communications in a tractor trailer combination. Furthermore, these devices are simple and economical to produce, and are adaptable for the standard J560 connector which already exists in the trucking industry to interface power between the tractor and the trailer.
An electrical connector for transferring multiple electrical signals from one cable on a trailer to another cable on a tractor of a tractor/trailer combination, comprising:
In an electrical system for a tractor/trailer combination, comprising a first and a second multi-conductor cable joined to each other by a connector, said connector having one part which comprises a multi-pin plug containing a plurality of pins and another part which is a multi-receptacle socket containing a plurality of receptacles matable with said pins, said first electrical cable being adapted to supply electrical power to said connector from said tractor and said second electrical cable being adapted to receive said power from said first electrical cable by way of said plug and socket, the improvement wherein:
