1. A vehicular window assembly, the vehicular window assembly comprising:
a window panel having an inner surface and an outer surface;
electrically conductive traces established at the inner surface of the window panel;
a pair of busbars established at the inner surface and in electrical connection with respective portions of the electrically conductive traces;
an electrical connector affixed at each busbar and configured to electrically connect to a wire harness of a vehicle when the vehicular window assembly is installed at the vehicle;
wherein each electrical connector comprises a bonding portion, a connecting terminal and a busbar-connecting portion;
wherein the connecting terminal of each electrical connector is configured to electrically connect to a respective connector of the wire harness of the vehicle;
wherein the bonding portion of each electrical connector is adhesively bonded at the window panel to affix the electrical connector at a respective busbar;
wherein, as the bonding portion of each electrical connector is adhesively bonded at the window panel, the busbar-connecting portion of the electrical connector flexes relative to the bonding portion of the electrical connector and is biased toward engagement with the respective busbar;
wherein, with the bonding portion of each electrical connector adhesively bonded at the window panel, the busbar-connecting portion of the electrical connector is pressed into engagement with the respective busbar and makes direct contact with the respective busbar to maintain electrical connection to the respective busbar; and
wherein the electrical connectors are bonded at the window panel with the busbar-connecting portions electrically connected to the respective busbars without use of solder.
