Definitions

  • the present invention relates to automobile glazing provided with a conductor structure placed on a glass surface, which comprises printed conductors baked in place on this glass surface as well as other conductors, arranged in a second plane and insulated by compared to the previous ones.
  • Automobile glazing fitted with electric conductors baked in place in the glass surface and made of a baking ink containing metallic silver is used mainly as heating glazing (DE-AS 19 11 561) or as antenna glazing (DE 21 45 968 C3).
  • automobile glazings which are provided with a structure of conductors baked in place in which this structure is an alarm loop connected to a signal transmitter (BE 0 418 123 A1).
  • conductive structures baked in place in the surface of the glass can be produced as humidity detectors (DE-PS 22 07 230), and placed directly on the surface of the glass, in the form conductor structures baked in place, inductors, capacitors and shielding cables (DE 20 14 643).
  • the conductor structures on the glass surfaces are usually screen printed and baked in place at a high temperature. With this technique, it is possible to produce, relatively inexpensively, relatively complex conductor structures in a plane.
  • the object of the invention is to provide an automotive glazing provided with conductors which extend partly in at least two planes, glazing with which, on the one hand, the risk of short circuits at the crossings of the conductors is safely excluded , and which, on the other hand, is simple to manufacture under the usual production conditions.
  • the conductors placed in another plane are metallic conductive ribbons which are located inside a prefabricated multilayer element, comprising at least one insulating layer, which is permanently fixed by a layer of adhesive on the surface of the glazing provided with baked conductors in place, and above these.
  • the conductors or the structures of conductors necessary in a second plane and, where appropriate, in other plans of conductors, are therefore prefabricated, according to the invention, on a support made of a monolayer or multilayer insulating film, and the Prefabricated multilayer elements are applied, by rolling, to the desired location on the glass surface, at the end of the glazing manufacturing process.
  • the prefabricated elements are provided with suitable connection surfaces, for example soldering connection surfaces, which allow the conductors of the prefabricated element to be electrically connected to the baked conductor structure and / or to the connection cables.
  • Figs. 1 and 2 show a first embodiment of an automotive glazing according to the invention.
  • the automotive glazing shown in part here is an electrically heated rear window in which horizontal heating conductors (2) are printed and baked in place on the glass (1), and which also has one or more antenna conductors galvanically separated from these heating conductors (2) and which are also printed and baked in place.
  • the antenna conductors themselves are not shown in the figures.
  • the antenna conductor placed above the heating conductor (2) shown is connected to a plug-in element (3) similar to a press button, which is fixed near the lower edge of the glass strip (1), that is to say below the heating conductor (2), and to which the cable leading to the antenna amplifier or receiver is connected.
  • This element (6) has, as an electrically conductive constituent, a thin metallic strip (7) whose thickness is for example from 30 to 80 ⁇ m and the width from 1 to 10 mm.
  • the electrically conductive constituent can also be a copper wire of 0.1 to 1 mm in diameter.
  • the metal strip (7) which is preferably made of copper, is surrounded by a flat insulating sheath (8) made of a suitable plastic material resistant to breakage.
  • the lower end of the element (6) widens into a circular end section (10) which has a central welding eyelet (11).
  • the insulating sheath (8) is removed above and below the metal strip (7), forming a circular open space, and the metal strip (7) has a concentric hole. (12).
  • the element (6) is bonded to the glass plate (1) by a layer of adhesive (13).
  • a sheath which is permanently and permanently fixed to the metal strip (7) a plastic material based on polyimide, for example, has given satisfaction, while, as an adhesive for fixing this element to the surface of the glass, it is in particular adhesives based on isoprene or acrylate which have proved their worth.
  • the circular terminal section (10) of the element (6) rests on a layer (15) of conductive enamel and solderable with tin, which, for example, consists of the same baking ink as the heating conductors ( 2) and the antenna conductor which was applied to the glass surface during the same printing operation as for these.
  • the plug-like element, on the one hand, and the welding eyelet (11) of the element (6), on the other hand, are soldered with tin to this layer d conductive enamel (15).
  • the welding between the welding eyelet (11) and the conductive enamel layer (15) is done, after the element (6) is placed on the glazing (1), by depositing solder on the 'tin (16) at the location of the welding eyelet (11); it flows through the hole (12) of the metallic tape (7) and it is welded to the layer of conductive enamel (15).
  • Figs. 3 and 4 show another embodiment of the invention.
  • it is also an automotive glazing that can be heated electrically, with heating conductors (19) printed and baked in place on the glazing (18).
  • An electronic module must be attached to the glass in the area of the heated surface.
  • This electronic module can be for example a humidity detector or any other electronic assembly.
  • the conductors leading to this module should preferably be brought, in a manner that respects aesthetics, to the upper edge of the glazing (18), where provision is made for connect a compact cable ensuring the rest of the link.
  • the crossing of the heating conductors (19) is done by means of a complex element (20) which is laminated or glued to the glazing (18).
  • This element (20) has, at one of its ends, a surface of mounting (21) intended for the module and, at its other end, a mounting surface (22) intended for a plug-in element with which the connection to the compact cable is established.
  • the electronic module can, at the location of the mounting surface (21), be integrated directly into the element (20) or, as a separate module, be placed on the mounting surface (21) at a later time.
  • the plug-in element can, at the location of the mounting surface (22), be integrated into the element (20) or be placed later on this mounting surface ( 22).
  • the element (20) has three conductors, namely a supply conductor (24), a signal conductor (25) and a control conductor (26), which are connected to the corresponding connection points, on the surfaces of mounting (21 and 22).
  • Fig. 4 shows the multilayer structure of the element (20).
  • the element (20) has, below the plane of the conductors, a metal sheet (29) which preferably extends over the entire width of this same element (20) .
  • This metal sheet (29) is connected to the ground terminal (30) on the mounting surface (21).
  • the metal sheet (29) serves as a ground conductor and, at the same time, as a shield conductor.
  • the upper insulating layer (27) is another layer of adhesive (28) in the middle of which is placed another metal strip (32) which serves as the upper shielding conductor for the signaling conductor (25 ) underlying. All of the layers are surrounded by an insulating sheath (34) made of a plastic material resistant to breakage, for example based on polyimide.
  • This element (20) is permanently bonded securely to the surface of the glazing (18), by means of a layer of adhesive (35).
  • Multilayer structures of this kind are known, in the technique of printed circuit boards, under the name of multilayers (in English: "multi-layer”).
  • the conductors can be produced in the context of printing processes, by printing the insulating sheets (27), by applying thin metallic ribbons, by doubling on the insulating sheets (27), or by doubling an insulating sheet on its entire surface by means of a copper foil and structuring of the copper foil using the etching technique by chemical attack.
  • a flat cable is produced and, by hot stamping or forming, the element (20) is obtained from this flat cable in its desired shape.
  • the element (20) is bonded to the surface of this glazing.
