A window pane has a substrate formed from glass and includes an electrical device including an electrical conductor. An electrical connector is operatively connected to and in electrical communication with the conductor for transferring electrical energy to the conductor. An electrical connector is bonded to the electrical conductor and has a first interacting portion. A terminal is disposed adjacent to the electrical connector and has a second interacting portion for interacting with the first interacting portion to mechanically couple the electrical connector and the terminal. The substrate has a first coefficient of thermal expansion and the connector has a second coefficient of thermal expansion. A difference between the first and second coefficients of thermal expansion is equal to or less than 5×10⁻⁶/° C. Due to the mechanical coupling between the connector and the terminal, the terminal and connector are less prone to bending, breakage, or delamination than conventional connector structures.

An antifogging window plate has a transparent film and a base both made of thermoplastic resins. Conductive lines and electrodes are printed using a conductive paste on one side of the film, which is then bonded to the base. One portion of each electrode is exposed as a terminal portion to be connected to an electric contact member. The window plate is made by injection molding with the surface of the film opposite from the printed surface being in contact with the cavity wall of the mold, so that the integration of the film with the base is effected simultaneously with the forming of base. Each contact member is subsequently fitted in an injection-molded void facing the terminal portion, or is secured in place at the same time as the injection molding.

Disclosed is a warm window system that utilizes individual buss bars that are placed within the space between an inside window pane and an outside window pane and creates sufficient physical force to create an electrical contact on the tin oxide layer on the inside surface of the inside pane of glass. An insulating nonconductive layer can also be used in conjunction with the buss bars. That include metal strips, braided wires, spring loaded indentations, etc. The buss bars have a modulus of elasticity to ensure sufficient electrical contact with the tin oxide layer. The buss bars can be used with either hard coat or soft coat tin oxide coatings on tempered glass or annealed glass. Electrical connections and wires are hidden from the viewing area of the warm window system to enhance the aesthetic value of the warm window system. Retrofit systems allow use of the warm window system in conjunction with an existing installed window system.
