  • Patent number: 4100398
    Abstract: A laminated electrically heatable window has a transparent electrically conductive layer embedded in the window to act as a sheet resistor, and conductive bus bars embedded in the window in contact with the resistive layer. A portion of each bus bar extends outside an edge of the window to a terminal connection for making electrical contact with a harness cable leading to an electric current source such as an automobile alternator. Each terminal connection comprises separate electrical contacts on the ends of the bus bar and the cable harness for forming a cooperating pin and socket connection normal to the bus bar. The electrical contacts are pressure fitted together and hermetically sealed from end-to-end in an electrically insulating, protective sleeve.
    Type: Grant
