Definitions

  • the invention relates to insulating glazing that includes an electrically conductive coating and/or an electrically controllable functional element.
  • Insulating glazing is increasingly being installed in glass facades on buildings for aesthetic reasons, especially if the facade is optically designed as an all-glass facade.
  • Such insulating glazing consists of at least two panes which are kept at a distance from one another by a spacer.
  • the panes can have a heat protection and/or sun protection coating.
  • Such coatings can also contain silver and thus enable a low transmission of infrared radiation. This can lower the temperature inside a building.
  • functional as well as optical and aesthetic features are increasingly playing an important role in the field of building glazing.
  • glazings with electrochromic properties or those with electrically controllable liquid crystal layers for controlling the light transmission have found increasing use.
  • Insulating glazing with an electrochromic coating requires an electrical connection and bus bars.
  • busbars present in insulating glazing are generally located within the glazing interior and are visible from both the outside and the inside, which reduces the visible area of the window and is also aesthetically unsightly.
  • a busbar is, for example, in the form of a strip or a wire.
  • the bus bar is made of an electrically conductive material such as silver or copper. It can be produced, for example, by printing a conductive silver paste onto the electrically conductive and/or electrically switchable coating for electrical contacting.
  • the baked conductive silver paste contains silver particles. If the silver paste is burned in, damage such as a short circuit between the surface electrodes of the electrochromic coating should be avoided.
  • WO 2020/173785 A1 discloses a glazing unit which has two glass panes connected to one another at a predetermined distance by a spacer profile.
  • One of the panes of glass has an electrically conductive coating on the inside of the glazing unit and a bus bar for electrically connecting the conductive coating.
  • the bus bar is provided with an opaque cover.
  • US 2014/133005 A1 discloses an electrochromic device having at least one bus bar and a color shading material, wherein the bus bar is coated with a coating material that is substantially non-porous and color-matched to the color shading material, a spacer or a polymeric seal.
  • the invention is therefore based on the object of specifying insulating glazing that is improved from an aesthetic and, in particular, functional point of view, which can be implemented simply and cost-effectively.
  • the object of the present invention is achieved according to the invention by an insulating glazing according to claim 1.
  • Preferred embodiments emerge from the dependent claims.
  • the insulating glazing according to the invention comprises at least two panes and at least one spacer which has two pane contact surfaces which run parallel to one another.
  • a first pane contact surface is connected to a first pane of the two panes via a sealant and a second pane contact surface is connected to the second pane via a sealant, so that a glazing interior and a glazing exterior are formed.
  • One of the two panes is at least partially provided with an electrically conductive coating and/or an electrically controllable functional element on the side facing the glazing interior.
  • At least one bus bar comprises an electrically conductive adhesive tape, the electrically conductive adhesive tape having an electrically conductive adhesive layer, a conductor track and an opaque, electrically insulating cover.
  • the busbars are preferably in the form of strips.
  • Opacity generally denotes the opposite of transparency.
  • the cover of the adhesive tape lacks transparency. It is opaque, cloudy or dark, especially black.
  • the insulating glazing according to the invention can achieve a significant improvement in the aesthetic appearance of the insulating glazing compared to the prior art, since the conductor track of the busbar is covered by the cover and is therefore less visible, particularly when viewed from the inside of a room.
  • the invention brings several advantages. On the one hand, considerable costs can be saved by using an electrically conductive adhesive tape. In addition, sticking the adhesive tape to the electrically conductive coating and/or the electrically controllable functional element can prevent a short circuit occurring between the electrode layers of the functional element as a result of burning busbars on the functional element.
  • the electrically conductive adhesive tape is connected to the electrically conductive coating and/or the electrically controllable functional element via the electrically conductive adhesive layer.
  • the electrically conductive adhesive layer contains at least one electrically conductive material, preferably a metallic material such as silver, gold or aluminum. It is also possible for the electrically conductive adhesive layer to contain a non-metallic, electrically conductive material, for example graphite or carbon.
  • the at least one electrically conductive material can be introduced into an electrically non-conductive adhesive matrix, for example epoxy resin.
  • the at least one electrically conductive material is contained in the adhesive layer in such an amount that a desired current-carrying capacity is achieved.
  • the at least one electrically conductive material is preferably contained in the adhesive layer with a mass fraction of at least 70%.
  • the trace of the adhesive tape is an electrical conductor whose width is significantly greater than its thickness.
  • the conductive trace is preferably made so thin (i.e. the thickness is small enough) that it is flexible and bendable.
  • the conductor track consists of a metal foil in the form of a strip or band.
  • the conductor contains copper, aluminum, tin, gold or silver.
  • the conductor track can also contain or consist of alloys with the metals mentioned.
  • the opaque, electrically insulating covering contains polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • the electrically conductive adhesive tape has a thickness of 50 ⁇ m to 1 mm, preferably 110 ⁇ m.
  • the adhesive tape can be 80 ⁇ m to 120 ⁇ m thick, with the adhesive layer having a thickness of 25 ⁇ m and the conductor track having a thickness of 35 ⁇ m. This results in the advantage that the adhesive tape is bendable.
  • the electrically conductive adhesive tape has a width of 1 mm to 10 mm, preferably 2 mm to 4 mm. Widths of this type are particularly suitable for achieving sufficient current-carrying capacity in conjunction with the above-mentioned thicknesses. It goes without saying that the length, width and thickness of the adhesive tape can be adapted to the requirements of each individual case.
  • the opaque, electrically insulating cover almost completely covers the conductor track of the electrically conductive adhesive tape. This has the advantage that the conductor track is better protected against corrosion and dirt.
  • a first busbar can extend along a first side edge of the electrically conductive coating and/or the electrically controllable functional element and a second busbar can extend along a second side edge of the electrically conductive coating and/or the electrically controllable functional element.
  • the two busbars are arranged on opposite sides of the insulating glazing in the interior of the glazing.
  • the busbars are preferably arranged in such a way that they are arranged horizontally when the insulating glazing is installed. However, it is also possible for them to be arranged vertically when installed.
  • a bus bar can also be routed around the corner, i.e. the bus bar is located on two sides of the insulating glazing which are connected to one another.
  • the busbar can also be designed to be interrupted, particularly in the case of large insulating glazing, and be designed in two parts.
  • the busbar then has two limbs which are angled towards one another and which are arranged at an angle to one another, in particular an angle of less than 180°, preferably approximately 90°.
  • the legs can be connected to one another in an electrically conductive manner, for example via an electrically conductive bridge element.
  • the bridge element has an electrically conductive material, for example copper.
  • a first leg can at least partially overlap a second leg, the first leg and the second leg being arranged at an angle to one another.
  • the second leg has a connection area for making electrical contact between the first leg and the second leg.
  • the opaque, electrically insulating cover of the second leg has a recess in the connection area.
  • the recess forms a material-free Passage to the conductor track of the second leg.
  • the recess is, for example, a rectangular, circular or oval opening in the opaque, electrically insulating cover, it being understood that any shape is possible in principle.
  • the volume of the recess is such that the first leg of the bus bar can be reliably and securely bonded to the conductor track of the second leg by means of the electrically conductive adhesive layer.
  • the connection area is advantageously of flat design and preferably consists of a non-insulated area of the second leg. Such flat connection areas are particularly suitable for making contact with electrically conductive adhesive tapes, since they have a large area that can be brought into contact with the electrically conductive adhesive layer of the adhesive tape and thus form a low-impedance electrical line connection.
  • the second leg has a first section, a second section and a fold, in which the first section and the second section of the second leg are arranged at least partially one above the other.
  • the first section being perpendicular to the second section and the adhesive layer of the second section facing the glazing interior.
  • the second section has an area in which the first busbar and the second busbar overlap, so that an electrically conductive connection is created between the first and the second leg of the busbar.
  • the second section has a contact region which is provided for electrical contacting with the first leg, so that an electrically conductive connection is created between the first leg and the second leg.
  • the insulating glazing comprises at least two panes which are kept at a distance from one another by at least one spacer.
  • Another name for insulating glazing is multi-pane insulating glass.
  • the insulating glazing can be, for example, double-pane insulating glass, which comprises two panes, triple-pane insulating glass, which comprises three panes, or four-pane insulating glass, which comprises four panes.
  • the insulating glazing preferably comprises two or three panes.
  • two panes are outer panes that are in contact with the outside environment.
  • An outer pane has one side, the inner side or inside, facing a glazing interior and the other side, the outer side or outside, the outside environment.
  • an outer pane is a laminated pane of at least two individual panes, in particular the outer pane, which faces outwards when installed. If the insulating glazing comprises more than two panes, one or more panes, the inner panes, are arranged between the two outer panes.

Accordingly, two or three such spacers are required for three-pane insulating glass and four-pane insulating glass, a first spacer for spacing one outer pane from the inner pane and a second spacer for spacing the other outer pane from the inner pane. Spacers are also known which can space three panes apart.
  • the spacer has an interior glazing surface connected to the two panel contact surfaces and an exterior surface connected to the two panel contact surfaces directly or via connection surfaces.

  • the height of the spacer can be, for example, in the range of 5 to 15 mm, preferably 5 to 10 mm.
  • the width of a spacer refers to the direction from one side contact surface to the other side contact surface. Height refers to the direction from the exterior surface to the interior glazing surface.
