Definitions

  • the present invention relates to a vehicle glazing, and in particular to a laminated vehicle glazing incorporating an electrical device, such as heating means.
  • Vehicle glazings especially windscreens and backlights (rear glazings) are often equipped with one or more electrical devices which require supply of electrical power to perform their function.
  • a common type of electrical device found in many vehicle glazings is a heating means which facilitates de-misting and/or de-icing of the glazings as and when necessary.
  • the heating means is typically in the form of printed conductive lines on a toughened backlight (although laminated backlights having a heatable conductive coating are also known) and in the form of an array of conductive wires or a heatable conductive coating in a laminated windscreen.
  • Heatable sidelights side glazings are also known; these may be provided with an array of wires or a coating.
  • Both an array of conductive wires and a heatable conductive coating each require a supply of electrical energy in order to perform their heating function.
  • Two or more electrically conductive busbars are usually provided as a part of the heating means, along with a suitable electrical connector, to enable connection of the heating means to a suitable power source.
  • each of the wires may be soldered at each end thereof between a pair of busbars which span the extent of the wires.
  • a pair of busbars may be provided such that at least two opposing edges of the coating are in contact with a busbar.
  • the busbars or other electrical devices are normally included within the laminate, i.e. between the panes of glazing material.
  • An electrical connector which electrically connects a busbar or other electrical device to a power source, e.g. the wiring loom of a vehicle, is thus usually partially included within the laminate also. This is where problems with prior art glazings arise.
  • an electrical connector extends from within a laminate (where it is connected to a busbar or other electrical device) to the environment surrounding the laminate, any moisture that may be present in the surrounding environment is liable to be drawn into the laminate via capillary action along the length of the flexible connector that contacts (but is not bonded to) a pane of glazing material within the laminate to the busbar or other electrical device, which may then be corroded and ultimately fail.
  • the strip of adhesive itself may be incorrectly positioned width- wise on the flexible connector such that one or more narrow channels are created which effectively bypass the adhesive strip.
  • the adhesive itself is believed to degrade over time, possibly because of moisture sensitivity.
  • An additional problem with the solution described above arises when a laminate is made using at least one thinner pane of glazing material (i.e. a pane of thickness 1.6 mm or less, which is thinner than the 2.1 mm thick panes usually employed). Inclusion of a strip of adhesive appears to increase the frequency with which at least one of the panes of glazing material fractures when the laminate is de-aired prior to being autoclaved.
  • the present invention provides in a first aspect a laminated glazing, for a vehicle, comprising two panes of glazing material having a single ply of interlayer material therebetween, an electrical device provided on a surface of the glazing, and an electrical connector, having two major faces, each face having a length and a width, in electrical contact with the electrical device, wherein interlayer material is provided across the width of each of the major faces of the connector such that each face of the connector is joined to the correspondingly adjacent pane of glazing material.
  • the electrical device is described as being "provided on a surface of the glazing" - by this is meant that the electrical device may be on a surface of one of the panes of glazing material, or on a surface of the ply of interlayer material.
  • the electrical connector may be a flexible electrical connector, in which case the flexible, plastics portion of the connector is that which has two major faces.
  • the laminated glazing comprises two panes of glazing material having a single ply of interlayer material therebetween, heating means, provided on a surface of the glazing, in electrical contact with two electrically conductive busbars, and an electrical connector, having two major faces, each face having a length and a width, in electrical contact with a busbar, wherein interlayer material is provided across the width of each of the major faces of the connector such that each face of the connector is joined to the correspondingly adjacent pane of glazing material.
  • Busbars are typically made from thin (less than 0.2 mm thick, usually 0.1 mm thick) strips of conductive metal, for example tinned copper, or from printed and fired silver-based conductive inks, or they may be made from a thermoplastic material in which particles of a conductive material are dispersed. Busbars are usually located along the top and bottom edges of the chosen substrate in a glazing as longitudinal strips. For the avoidance of doubt, use of the terms "top”, “bottom” and “side” in relation to a glazing, or its component parts, in this specification is made with reference to the orientation of the glazing when fitted into a vehicle.
  • busbars may extend down one side of the glazing to allow convenient connection of both busbars to a power source, or a closed loop of busbar material may be appended to a busbar, all of which are within the scope of the present invention.
  • the panes of glazing material may be panes of glass, preferably soda-lime-silica glass which may be clear or body-tinted, or they may be panes of a rigid plastics material such as polycarbonate.
  • the two panes may be made of the same material or one may be glass and one may be plastic.
  • the panes of glazing material are used in a thickness between 1 and 10 mm, preferably between 1.5 and 6 mm.
  • the ply of interlayer material may be a flexible plastics material, which may be clear or body-tinted.
  • Suitable interlayer materials include polyvinyl chloride (“PVC”), polyurethane (“PU”), ethyl vinyl acetate (“EVA”), polyethylene terephthalate (“PET”) and polyvinyl butyral (“PVB”), the most common choice for lamination being PVB, typically used in 0.76 mm thickness, although 0.38 mm thickness is also used.
  • One way of enabling provision of interlayer material across the width of each of the major faces of the connector is to provide a first slit in the ply of interlayer material, through which the electrical connector passes from a first side of the ply to a second side, where it is connected to the electrical device (e.g. the busbar of a heating means).
  • a preferred extension of this concept is to provide a second slit in the ply of interlayer material, through which the electrical connector passes from the second side of the ply returning to the first side, where it is connected to the electrical device (e.g. the busbar of a heating means).
  • the connector is weaved through the ply of interlayer material.
  • a yet further extension of the concept may be that the first and second slits, along with a third slit which extends from the first slit to the second slit, form a flap, under which the electrical connector passes from the first side to the second side returning to the first side of the ply of interlayer material.
  • a flap may be advantageous in that it may merely be lifted whilst the electrical connector is positioned beneath it, and then released over the connector, rather than feeding the connector through first and second slits in the interlayer ply.
  • the flap would have to be correctly positioned back over the connector to prevent the occurrence of a capillary channel to the busbar.
  • the first slit in the ply of interlayer material may be located adjacent to an edge of the ply such that the distance from the edge of the ply to the first slit is preferably at least 5 mm, further preferably in the range 7 to 15 mm and most preferably in the range 8 to 12 mm.
  • Such an amount of interlayer material is thought to be sufficient to ensure a moisture-impermeable seal between the electrical device (e.g. the busbar of a heating means), the electrical connector and the environment surrounding the laminate.
  • the second slit in the ply of interlayer material is typically located inboard of, and substantially parallel to, the first slit and the distance between them is preferably at least 2 mm, further preferably in the range 3 to 8 mm and most preferably in the range 4 to 6 mm. Again such an amount of interlayer material is thought to be sufficient to ensure a moisture-impermeable seal to the electrical device (e.g. the busbar of a heating means).
  • An alternative manner of enabling provision of interlayer material across the width of each of the major faces of the connector is to contact one of the faces of the connector with the ply of interlayer material and to provide a separate piece of interlayer material, having first and second elongate edges, across the width of the opposing face.
  • the separate piece of interlayer material is a piece of the ply of interlayer material which has been excised from the ply, leaving an elongate aperture in the ply.
  • the connector may pass over the elongate aperture (which may extend along the width of the connector) and the piece of interlayer material laid over both the connector and the aperture below.
  • the first elongate edge of the separate piece of interlayer material may be located adjacent to an edge of the ply of interlayer material such that the distance from the edge of the ply to the first elongate edge is preferably at least 5 mm, further preferably in the range 7 to 15 mm and most preferably in the range 8 to 12 mm.
  • Such an amount of interlayer material is thought to be sufficient to ensure a moisture-impermeable seal between the electrical device (e.g. the busbar of a heating means), the electrical connector and the environment surrounding the laminate.
  • the distance between the first elongate edge and the second elongate edge of the separate piece of interlayer material is preferably at least 2 mm, further preferably in the range 3 to 8 mm and most preferably in the range 4 to 6 mm. As above, such an amount of interlayer material is thought to be sufficient to ensure a moisture-impermeable seal to the electrical device (e.g. the busbar of a heating means).
  • the electrical device may comprise an array of electrically conductive wires, in which case the wires are preferably embedded into the ply of interlayer material.
  • the heating means may comprise an electrically conductive coating, which may be a layer of any conductive coating known in the art for the purpose of heating a vehicle glazing, and it may be provided by any suitable method known in the art, for example chemical vapour deposition.
  • the layer may be a single layer (many nanometres thick) or it may be a composite stack of two or more layers, which need not be identical.
  • the coating may be provided on a surface of one of the panes of glazing material, or preferably on a surface of the ply of interlayer material, usually a ply of PET which itself may be typically interleaved between two plies of PVB forming a composite interlayer, which is used to laminate the two panes of glazing material together.
  • a laminated glazing according to the present invention may advantageously be used as a vehicle windscreen and/or a backlight and/or a sidelight.
  • a method of manufacturing a laminated glazing as per the first aspect of the invention comprising providing a surface of the glazing with an electrical device, making electrical contact between a) the electrical device, and b) an electrical connector, having two major faces, each face having a length and a width, assembling two panes of glazing material and a single ply of interlayer material such that the electrical device, the electrical connector and the ply of interlayer material are between the panes of glazing material, and subsequently laminating the assembly, wherein, during assembly, interlayer material is provided across the width of each of the major faces of the connector, thereby enabling each face to be joined to the correspondingly adjacent pane of glazing material.
  • the method of manufacture comprises providing a surface of the glazing with heating means, making electrical contact between a) the heating means and two electrically conductive busbars, and b) an electrical connector, having two major faces, each face having a length and a width, and a busbar, assembling two panes of glazing material and a single ply of interlayer material such that the heating means, the busbars, the electrical connector and the ply of interlayer material are between the panes of glazing material, and subsequently laminating the assembly, wherein, during assembly, interlayer material is provided across the width of each of the major faces of the connector, thereby enabling each face to be joined to the correspondingly adjacent pane of glazing material.
  • a first slit in the ply of interlayer material may be provided, through which the electrical connector is passed from a first side of the ply to a second side, where it is connected to the electrical device (e.g. the busbar of a heating means).
  • a second slit may be provided in the ply of interlayer material, through which the electrical connector is passed from the second side of the ply returning to the first side, where it is connected to the electrical device (e.g. the busbar of a heating means).
  • the connector is weaved through the ply of interlayer material.
  • the first and second slits, along with a third slit which extends from the first slit to the second slit, may advantageously form a flap, under which the electrical connector is passed from the first side to the second side returning to the first side of the ply of interlayer material.
  • interlayer material may be made by contacting one of the faces of the connector with the ply of interlayer material and providing a separate piece of interlayer material, having first and second elongate edges, across the width of the opposing face.
  • the separate piece of interlayer material is excised from the ply of interlayer material, leaving an elongate aperture in the ply.
  • the connector may be passed over the elongate aperture (which may extend along the width of the connector) and the piece of interlayer material subsequently laid over both the connector and the aperture below.
  • Figure 1 is a plan view of a laminated glazing
  • Figure 2 is a cross-section along line A-A of Figure 1
  • FIGS 3a, 4a and 5a are detailed views of the glazing of Figure 1 ( Figure 3a representing the prior art), and
  • Figures 3b, 4b and 5b are detailed views taken from Figure 2 ( Figure 3b representing the prior art).
  • Figure 1 illustrates a laminated glazing 10 comprising outer ply of glazing material 11, in the form of a pane of glass, and upper busbar 13 and lower busbar 14, each in the form of tinned copper strips, within the laminate and located adjacent the top and bottom edges respectively thereof.
  • Upper busbar 13 and lower busbar 14 form part of an electrical device 17 (described in more detail in the following paragraph), and each has an electrical connector 15, in the form of a flexible connector, electrically connected to it, typically by soldering.
  • Outer ply of glazing material 11 is laminated to inner ply of glazing material 12, also in the form of a pane of glass, by a single ply of interlayer material 16, in the form of PVB, as shown in Figure 2.
  • plies of interlayer material may be included within the laminate construction, provided interlayer material is present across the width of each of the major faces of electrical connector 15 such that each face of connector 15 is joined to adjacent panes of glazing material 11, 12.
  • outer ply of glazing material is meant the ply that contacts the environment external of a vehicle into which the glazing may be fitted; by “inner ply of glazing material” is meant the ply that contacts the internal environment of said vehicle.
  • heating means 17 is also an electrical device in the form of heating means 17, itself in the form of an array of narrowly spaced, thin (less than 50 ⁇ m in diameter) metallic (e.g. tungsten) wires which span substantially the entire surface area of the glazing.
  • heating means 17 may be in the form of a transparent electrically conductive coating, for example a silver-based coating.
  • Figure 2 shows that heating means 17 is provided adjacent surface 2 of glazing 10, i.e. on the inner surface of outer pane of glazing material 11, usually on ply of interlayer material 16.
  • the surfaces of each of the panes of a glazing are consecutively numbered inwardly from the surface that contacts the environment on the exterior of a vehicle to the surface that contacts the environment inside the vehicle.
  • Heating means 17 extends between upper busbar 13 and lower busbar 14, which are also usually provided ply of interlayer material 16. Upper busbar 13 and lower busbar 14 provide electrical current to heating means 17, via electrical connectors 15, when connected to a power source, thereby enabling heating means 17 to perform its function.
  • FIGS 3 a and 3b depict certain parts of a prior art laminated glazing; they show the way in which electrical connector 15 is connected to lower busbar 14 between panes of glazing material 11,12.
  • Lower busbar 14 (and similarly upper busbar 13 - not shown here) comprises first busbar portion 14a, provided on ply of interlayer material 16, and second busbar portion 14b, which effectively "sandwiches” connector 15 and heating means 17 between itself and first busbar portion 14a (solder, not shown, being used to ensure electrical connectivity).
  • a problem with this configuration arises because there is no seal between connector 15 and outer pane of glazing material 11 post-lamination (whereas connector 15 is adhered to inner pane of glazing material 12 via ply of interlayer material 16). Lack of a moisture-impermeable seal means that moisture can be drawn under capillary action along connector 15 to, and subsequently corrode, lower busbar 14.
  • Figures 4a and 4b, and 5a and 5b depict the same parts of a laminated glazing as shown in Figures 3a and 3b, but now also the invention which solves the problem shown in Figures 3a and 3b.
  • Electrical connector 15 and heating means 17 are again “sandwiched” between first busbar portion 14a and second busbar portion 14b of lower busbar 14, however connector 15 is no longer merely laid onto ply of interlayer material 16.
  • connector 15 is passed from the underside of interlayer ply 16 through a slit 18 therein to the surface on which lower busbar 14 is provided. Connector 15 is then “sandwiched” into position between first and second busbar portions 14a, 14b as already described.
  • Suitable flexible connectors 15 may be obtained from a supplier such as Delphi Corporation, World & North American HQ, 5725 Delphi Drive, Troy, Michigan 48098-2815 US (www.delphi.com) or Labone Precision, Lower Middleton Street, Ilkeston, Derbyshire, DE7 5TN, UK (www.ralabone.co.uk).
  • Each sample glazing was then subjected to a salt-spray test, to check the corrosion resistance of the busbars.
  • the test conforms to the standard DIN 50021.
  • the samples were put into a chamber and electrically connected to a power source via connectors 15.
  • the chamber was sealed, the temperature inside set to a constant 35 0 C and a 5 % salt solution continually sprayed into it.
  • a cyclic supply of a current of 32 amps was supplied to the samples for 30 minutes, followed by 0 amps for 30 minutes, and then 32 amps again for 30 minutes, etc..
  • the samples remained in the chamber under these conditions for 25 days (although periods of between 15 days and 50 days may also typically be used for this test). After 25 days, the samples were removed and underwent a two-stage inspection process.
