Laminated electrically heatable window with electrical connectors
First Claim
1. A laminated electrically heatable window comprising:
- a pair of transparent face plies,a transparent laminate between the face plies, the transparent laminate including an electrically resistive heating element,an electrically conductive lead in contact with the resistive element, a portion of the electrically conductive lead extending outside an edge of the face plies,an electrical cable for conducting electric current to the resistive element,first electrical connector means comprising a first electrical contact means on the end of the portion of the electrically conductive lead extending outside said edge of the face plies, and second electrical contact means on the end of the cable,the first and second electrical contact means being engageable as a cooperating electrically conductive pin-and-socket connection for conducting electric current to the resistive element, the electrical contact means including means cooperating to form an electrically insulated exterior surrounding the engaged pin-and-socket connection,means electrically insulating the portion of the electrical lead extending outside said edge of the face plies and at least a portion of the electrically conductive lead embedded between the face plies near said edge of the face plies,means forming a seal around the electrically insulated embedded portion of the electrically conductive lead, andsecond electrical connector means for making electrical contact with said electrically resistive heating element.

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.
