Definitions

  • the invention relates to a glass element, in particular to an alarm window presenting the Characteristics of the preamble of claim 1.
  • the structure conductive is, in addition to its conductive portions covered by the spacer frame, made to from a baking dough with a high silver content, electrically conductive, which is deposited on the glass by screen printing. Then we print in a second layer an enamel-type protective layer for cover at least the portions of conductors to cover with the spacer frame. The two layers are cooked during the pre-stress heating of the glass, the protective layer being insulated electrically after cooking. We must therefore share obtain with certainty an electrical insulation of the conductive structure against unforeseen contact with the spacer frame (metallic), and on the other hand protect electrical conductors against corrosive influences.
  • the baked enamel protective layers in the crossing devices present however small pores, which may contain water.
  • the insulation resistance and protection against corrosion can be significantly reduced.
  • the underlying layer of baking dough conductive must first be completely dried before the printing of the protective layer. This requires a relatively long storage time for each individual glass, which strongly slows the flow of production and lengthens the overall time production.
  • a layer of plastic at least on the fittings to be insulated from the conductive structure.
  • This layer can for example consist of a sheet slim.
  • the layer or the protective sheet is only attached to the glass, preferably with an adhesive, only after preload / cooking.
  • it can already be provided beforehand with an adhesive layer, which is first covered with a protective sheet removable.
  • the conductors of electrical connection are assembled to the layer of plastic already before laying it on the surface glass, the electrical conductors being made in the form of thin metal lamellae and the layer of plastic serving as a backing sheet for these metal slats.
  • the conductive structure is provided with its two ends, for example of connection faces, brazing points respectively, to which the free and possibly pre-tinned ends of metal slats can be brazed after cooking.
  • connection faces can be arranged on the main face of the glass, the inside of the face circumscribed by the frame spacing so that only the conductors of brazed connection must be led to outside.
  • the layer of plastic and if necessary also the conductors themselves are pre-provided with an adhesive layer on their surface facing the glass, which layer adhesive suitable for hermetically sealing the slot between the glass surface and the plastic layer.
  • the connecting conductors of the structure conductive can also be formed by a cable flat with thin metal strips, which are sheathed by two thin layers or sheets of plastic and which are only stripped and possibly pre-tinned only at the ends to be connected to the structure conductive.
  • the plastic layer surface to be placed on the glass must be provided with a adhesive layer suitable for hermetically sealing the gap between the glass surface and the layer of plastic.
  • the cable flat can be led under the spacer frame, after that the metal strips have been connected, suitably, for example brazed, to the faces of connection of the conductive structure.
  • the material preferred polyimide for the layer or sheet of plastic is heat resistant enough to also withstand soldering at the soldering points covered by the plastic layer.
  • the invention also relates to methods for manufacture such glass elements. These processes are distinguish in particular by the procedures, modified from the state of the art, when cooking the printed conductive structure and the subsequent application of the protective layer, possibly also of the subsequent connection of connection conductors to lead to the outside.
  • the alarm glazing 1 is constructed in a known manner in the form of glazing two-pane insulation and includes a 2-pane pre-stressed silica glass and a glass pane 3 of normal silica, not prestressed (Floatglas). Both windows 2 and 3 are assembled to each other with interposition of a spacer frame 4, which consists of a hollow profile filled with a dehydrating agent 5.
  • the hollow profile can be made of metal (for example aluminum) or plastic.
  • the frame spacing may also differ from the representation and be an extruded plastic bead with an agent desiccant incorporated.
  • the waterproof bonded assembly of windows and the spacer frame 4 is provided by the bonding layers 6 butyl rubber and ground seal 7, the latter being introduced after assembling windows 2 and 3 with the frame spacer coated with bonding layers 6, in the hollow groove formed by the latter and the edges protruding windows.
  • it can be consist of thiocol, polysulfide, silicone or polyurethane.
  • a conductive structure 10 is formed inside the surface circumscribed by the spacer frame 4.
  • the connecting conductors 11 of the conductive structure 10 terminate at the edge of the glass by brazing points 12, to which the free ends 13 of insulated wires 14 are electrically connected. These connect the conductive structure to an external circuit not represented.
  • the entire conductive structure is preferably deposited by serigraphy of a paste of ceramic firing in high brazing material silver content with a thickness of about 0.01 mm. This dough is cooked by the heating necessary to the pretensioning of the window 2.
  • the parts of the conductive structure 10 adjacent to the spacer frame 4 are parallel to it at a distance large enough to completely exclude safety an electrically conductive contact with the spacer frame.
  • zone 11 'of the conductors connection to be covered by the spacer frame which is indicated by two parallel lines mixed, a thin layer of plastic 15 using a bonding layer (Fig. 2) so as to obtain a durable and superficial assembly between the plastic and the face of the glass.
  • a bonding layer Unlike of representation it is not absolutely necessary to extend the plastic layer until outer edge of the glass, but just insulate with this the parts of the conductors of connection 11 actually covered by the frame spacing 4.
  • the sectional representation of Figure 2 explains the bonding of the plastic layer in zone 11 '.
  • the layer of collage 16 intimately covering these under the plastic layer 15, the butyl bonding layer 6 as well as the profile of the spacer frame 4.
  • the bonding layer 16 must be sufficiently thick and flowing, to coat with certainty also transitions from the smooth glass face to the lamellae printed conductors of the connections as well as for protect these against corrosion.
  • the material for the bonding layer 16 preferably a butyl adhesive, for example the same material only for bonding layers 6, or a modified acrylate adhesive, while the layer of plastic preferably consists of polyimide or polyethylene.
  • the 11 printed and baked connections of the structure conductive 10 are not extended over zone 11 ' covered by the spacer frame 4, for a configuration for the rest unchanged from that of Figure 1, but they already end before, that is to say inside the intermediate space of the glazing, or even just in this zone 11 ', by soldering points 12 '.
  • this modified connection point can be optimized so that only a portion is visible very short end of the ribbon cable inside the intermediate space of the glazing; if applicable, the flat cable can also end flush with the edge inside the butyl glue layer 6 and stay thus practically invisible in space glazing. It just depends on the makes the connections completely covered by the sheet (upper) 19 of the flat cable to inside zone 11 '. For this purpose, it is wise to make this sheet out of a material heat resistant plastic, which supports without damage the brief heat input required for the soldering of the ends of the conductors with the points brazing 12 '. Polyimide or also polyethylene have been found to be suitable materials for these Goals.
  • the section shown in Figure 4 again explains the realization of this electrical connection under the frame spacing 4.
  • a bonding layer 16 ′ which assembles intimately, superficially and hermetically the flat cable 17 with the surface of the glass, the two sheets 18 and 19 as well as the conductors 20 of the flat cable, the layer butyl glue 6 and the spacer frame 4.
  • the flat cable can be at prerequisite with an adhesive layer on its face facing the window 2.
