Definitions

  • the structure of conductors is, in addition to its line sections covered by the part spacer, preferably made from a baking batter electrically conductive, high silver content, which is applied to the glass by screen printing. Then a layer of enamel protection is printed in the background like overlap at least on the sections of lines to be covered by the spacer.
  • the protective layer providing electrical insulation after cooking. So, from a apart we must surely reach an electrical insulation of the conductor structure against unexpected contact with the workpiece spacing (metallic) and on the other hand we protect the lines electric against corrosive influences.
  • the electrical resistance must be greater than 10 M ⁇ for the assembly consisting of the aforementioned insulating enamel layer, the glue and possibly a secondary sealant added to the outer perimeter.
  • the quality of the insulation (Quality of insulation) between the alarm loop and the room spacing is in total determined by the materials deposited between them (enamel covering layer or the like, glue lines).
  • the baked layers of enamel covering - the mostly in continuous industrial plants - have small pores, which may contain water.
  • the electrical resistance of the insulation can thus be substantially scaled down.
  • the adhesives used so far in the insulating glazing elements for the frame of spacing namely in general butyl lines colored in black with soot for visual reasons, do not exhibit either sufficiently high insulation levels and contribute too little to the quality of insulation.
  • the glue line is reduced to a thickness a few tenths of a millimeter when pressing the laminate, so you need very high levels of insulation there electric.
  • Document DE-C1-199 60 450 presents an isolation of the sections of lines using an assembled plastic layer mechanically or materially on the surface of the glass after the quenching, which may for example consist of a thin sheet.
  • the thin insulating sheet at the same time time a backing sheet for fittings made from of a flat conductor.
  • the object of the invention is to propose another variant of a glazing element of the type mentioned in the introduction, relatively simple to manufacture, with electrical insulation improved. You must also indicate a manufacturing process such glazing elements.
  • this objective is achieved, as far as concerns the glazing element, because the line of adhesive composes, over a predetermined distance in the area of crossing, of a material with an electrical insulation effect markedly increased compared to the material of the rest of the line glue.
  • this measure can meet the requirements quality of insulation, so that the line of glue highly insulating itself forms the protective layer (single) in the crossing zone with the fittings, even if it is only a few tenths of a millimeter thick. It may however be necessary or worthwhile to plan yet there additional protective layers, depending on the state of the aforementioned technique (therefore intermediate layers of enamel or glass, plastic sheets, etc.). These layers can be applied directly to the fittings. In principle, however, we could also drown them in the line of glue or apply them on the spacer itself, if the gas tightness required for the insulating glazing element remains insured in this area.
  • Said crossing zone is generally arranged in a angle of the glazing element, because this is where you can more easily find room for contacting of the external connections of the conductor structure. If necessary, it can naturally be provided in one place any one, as well as providing more than one of such connection areas in a glazing element, which must then each be electrically isolated in the same way.
  • a structure of conductors (preferably by screen printing), including fittings extend to near the edge of this window, respectively from the surface thereof.
  • connection faces i.e. soldering zones, which lie flat on the surface of the glass, over a certain width, parallel to the workpiece spacing, as shown in document DE-C1-199 60,450 already mentioned.
  • extension lines for connecting the structure of conductors to an external circuit not shown, for example a alarm device or radio installation using or by configuring the antenna conductor structure.
  • the parts of the conductor structure adjacent to the part spacers are oriented parallel to it, at a distance large enough to exclude with certainty a conductive electrical contact with the spacer. Likewise, the connections of different electrical polarity, led to outside parallel to each other, respect a distance a few millimeters apart.
  • the entire conductor structure in addition to the lines of connection and soldering zones, is preferably deposited by serigraphy of a ceramic paste to be cooked in a material of brazing with high silver content, with a thickness of about 0.01 to 0.03 millimeter. This dough is cooked by heating to high temperatures necessary for tempering the glass.
  • the electrical conductivity is quite sufficient for cases of application described, even with such small sections cross.
  • the spacer itself itself usually consists of a hollow profile filled with a drying agent. This one moves consist of metal (e.g. aluminum) or material plastic.
  • layers, respectively lines, of glue of a thickness also uniform as possible can be applied either directly on the faces of the panes along the region of their contact with the spacer is (preferably) on the spacer itself.
  • the lines glue are made of butyl rubber, which adheres remarkable and durable as well to glass surfaces than metal and which can be deposited continuously by extrusion in the form of a bead or line on the face concerned pieces.
  • the material is now removed again, for example by cutting a piece in the continuous line.
  • the interval can also be produced first necessary by locally stopping the deposit operation, respectively of extrusion. We can for example start this last on a first side of the crossing area, one certain distance from the neighboring connection and, after tracing around the perimeter of the frame, finish it on the other side of the area, also at some distance from the next fitting.
  • these zones, of crossing one provide sufficient distance from the spacer and its bonding to the edge of the glass, respectively a protrusion of the face of the glass beyond the face covered by the spacer, in order to have a place sufficient for the electrical contacting of the connections of the structure of conductors led out of space circumscribed by the spacer, in a place visually hidden.
  • This zone as well as the contact zones of the lines of glue with the glass are often still visually hidden at by means of an opaque surface printing, which is directly on the face of the panes, below the fittings. This printing can also be done by screen printing and cooking. It can also be used as a basis for possible adhesion aids ("primer").
  • the glue line When pressing windows in conventional construction, the glue line is strongly compressed. Under these conditions, the material could also flow laterally outwards, below the spacer, and in circumstances even touching said connection lugs and creating a (too) poorly insulating connection between the connection terminal and the spacer.
  • the size of the interval, respectively the area with adhesive highly insulating is, for safety, chosen according to the size of the connection lugs, respectively of the faces of brazing. In an embodiment in which the faces of soldering have a total length of 45 mm, the area to be provided or coating with highly insulating adhesive mass is thus worth approximately 50 mm.
  • the adhesive with high levels electrical insulation used to bridge the gap in the "normal" glue line must be compatible with it. It is precisely in the junctions that the tightness of the line of finished glue must remain insured against gas penetration in laminated insulating glass. We can consider this as creating seamless junctions between most of the of the glue line and the section (s) inserted as needed in the crossing area. Naturally, there remains a heterogeneity in the junctions even after the crushing of the glue line, which can become visible upon inspection more careful even in the case of identical coloring of the two materials; however, this should in no way result in reduced sealing.
  • the piece to be inserted can be extruded in situ or be inserted as a prefabricated intermediate piece. The case where appropriate, the junctions with the rest of the line must then be smoothed.
