Electrical circuit with passive wiring connector for electrical device mounted on vehicle window
View Patent ↗A vehicle includes a vehicle body that supports an electrical line that is electrically connected to a power source and that terminates at a first terminal. The vehicle also includes a window member with an electrical device supported thereon. A second terminal of the electrical device is supported on the window assembly, and the window member is moveable relative to the vehicle body. The vehicle further includes a passive electrical connector with a plunger that moves between a retracted position and an extended position. The passive electrical connector also includes a biasing member that biases the plunger toward the extended position. The passive electrical connector electrically connects the first and second terminals when the window member is in a first position. The plunger is biased toward the extended position when the window member is in the second position to electrically disconnect the first and second terminals.

9. The vehicle of claim 1 , wherein the vehicle body includes a lower body portion and a cap portion, the cap portion being removably supported on the lower body portion, the window member being rotatably coupled to the cap portion to move between a closed position and an open position relative to the cap portion, the window member being in the first position when the window member is in the closed position and the cap portion is supported on the lower body portion, the window member being in the second position when either the cap portion is removed from the lower body portion or the window member is in the open position.
10. The vehicle of claim 1 , wherein the vehicle body includes a rear wall with a gate that is pivotally coupled to a surrounding portion of the rear wall to move between an open position and a closed position, the window member being in the first position when the gate is in the closed position, the window member being in the second position when the gate is in the open position.
11. The vehicle of claim 1 , wherein the vehicle body defines a side wall of the vehicle and a rear wall of the vehicle, and wherein the window member defines a rear window of the vehicle that is operably supported by the rear wall of the vehicle.
12. The vehicle of claim 1 , wherein the vehicle body includes a rear wall with a gate that is pivotally coupled to a surrounding portion of the rear wall to move between an open position and a closed position, the window member being in the first position when the gate is in the closed position, the window member being in the second position when the gate is in the open position, the mount of the passive electrical connector fixed to the gate.
13. A vehicle comprising:
a vehicle body that at least partially defines an interior area of the vehicle, the vehicle body operably supporting an electrical line that is electrically connected to a power source and that terminates at a first terminal;
a rear window member with a transparent plate and a framing member that frames the transparent plate, the framing member having a lower portion extending blow a bottom edge of the transparent plate, the rear window member being moveable relative to the vehicle body to move between a first position and a second position;
a defogger that is operably mounted to the rear window member, the defogger including an electrical line that extends across the transparent pane and the framing member and that terminates at a second terminal supported on an inner side of the lower portion of the framing member; and
