Description

The invention relates to a connection arrangement consisting of a ribbon cable with a protective housing.

Glazing in buildings and vehicles is increasingly being provided with large-area, electrically conductive functional layers that are transparent to visible light. In particular, for reasons of energy saving and comfort, high demands are placed on glazing with regard to its heat-insulating properties. It is therefore desirable to avoid a high level of heat input through solar radiation, which leads to excessive heating of the interior and in turn results in high energy costs for the necessary air conditioning. This can be remedied by layer systems in which the light permeability and thus the heat input due to sunlight can be controlled by applying an electrical voltage. Electrochromic layer systems are made of, for example EP 0867752 A1 , US 2007/0097481 A1 and US 2008/0169185 A1 known. Such layer systems are usually switched by external switches that are located in the vicinity of the glazing. Another function of electrical functional layers is aimed at keeping the field of vision of a vehicle window free from ice and mist. Electrical heating layers are known (see e.g. WO 2010/043598 A1 ), which by applying an electrical voltage cause targeted heating of the pane. The voltage that is applied to the electrical heating layer is usually controlled by external switches that are integrated into a dashboard in vehicles, for example. For example from DE 10106125 A1 , DE 10319606 A1 , EP 0720249 A2 , US 2003/0112190 A1 and DE 19843338 C2 it is known to use an electrical functional layer as a planar antenna. For this purpose, the functional layer is coupled galvanically or capacitively with a coupling electrode and the antenna signal is made available in the edge area of the pane. The antenna signal decoupled from the planar antenna is fed to an antenna amplifier which is connected to the metal body in motor vehicles, whereby a high-frequency reference potential for the antenna signal is specified.

Such composite panes generally consist of at least two rigid individual panes of glass which are bonded to one another in a two-dimensionally adhesive manner by a thermoplastic adhesive layer. The electrical functional layer is located between the individual glass panes and is typically electrically connected to the external environment via a flat conductor. The reason for this is that suitable flat conductors generally have a maximum total thickness of 0.3 mm. Such thin flat conductors can be embedded between the individual glass panes in the thermoplastic adhesive layer without difficulty. Examples of flat conductors for contacting electrical functional layers in composite panes in the vehicle sector can be found in DE 42 35 063 A1 , DE 20 2004 019 286 U1 or DE 93 13 394 U1 .

The use of flat conductors in composite panes with electro-optical components is also known. These are flat structures with electrically controllable optical properties of an active layer. This means that the optical properties of the active layer and in particular its transparency, scattering behavior or luminosity can be controlled by an electrical voltage. Examples of electro-optical components are SPD elements (SPD = Suspended Particle Device) which, for example, consist of EP 0876608 B1 and WO 2011033313 A1 are known, and PDLC elements (PDLC = Polymer Dispersed Liquid Crystal), for example from DE 102008026339 A1 are known.

The electrical contacting of electrical functional layers and electro-optical components is usually carried out on busbars, which are applied in the edge area of the functional layer or the electro-optical component and make electrically conductive contact with them. By connecting the busbars to an external voltage source, typically via flat conductors attached to the busbars, a voltage is applied and the functional layer or electro-optical component is switched.

In practice, flat cables are used for more complex control tasks, which are provided with a plurality of electrical conductor tracks. The electrical conductor tracks are very thin with thicknesses, for example, in the range from 0.03 mm to 0.1 mm and consist, for example, of copper, which has proven itself because it has good electrical conductivity and good processability and the material costs are low at the same time.

Such ribbon cables typically have connectors such as plugs or sockets that are pre-assembled on one side, with which the ribbon cables can be connected to external electrical devices. However, these connecting pieces are sensitive to dust, dirt and moisture and are only partially suitable for surviving a lamination process undamaged.

In contrast, the object of the present invention is to provide an improved To provide connection arrangement in which the connectors are protected.

These and other objects are achieved according to the proposal of the invention by a connection arrangement according to the independent patent claim. Preferred embodiments emerge from the subclaims.

Another aspect of the invention relates to a connection arrangement with a composite pane and a ribbon cable, at least comprising:

• - A composite pane made of a first pane and a second pane, which are connected to one another in terms of their surface area via at least one thermoplastic intermediate layer,
• - an electrical functional element between the two panes,
• - A ribbon cable with electrical conductor tracks, the ribbon cable having a first connection area at a first end and a second connection area at a second end, the first connection area being arranged between the two panes and the second connection area being led out of the composite pane between the two panes, and wherein the electrical conductor tracks in the first connection region make electrical contact with the electrical functional element, and
• - One or more electrical connection pieces, selected from a plug or socket, which are firmly connected in the second connection area to the ribbon cable, the electrical connection pieces being provided for the electrical plug connection with an electrical connection counterpart selected from a plug or socket,

whereby

• - The connecting pieces are each surrounded by a protective housing at least in sections and preferably on one side.

In an advantageous embodiment of the invention, each connection piece has first electrical connection means, which are each electrically connected to an electrical conductor track and are intended to be contacted with second electrical connection means of a respective connection counterpart.

The connection arrangement according to the invention thus comprises a composite pane made of a first pane and a second pane, which are firmly connected to one another in terms of area via a thermoplastic intermediate layer.

The connection arrangement further comprises an electrical functional element, which is arranged between the two panes, and a ribbon cable, which is used to make electrical contact with the electrical functional element, in particular in the connection area of the composite pane for electrically connecting the functional element to an electrical control system. The ribbon cable has a first connection area and a second connection area, the first connection area being located at a first end and the second connection area being located at a second end of the flat cable along a direction of extension of the flat cable. The ribbon cable is partially laminated into the composite pane, the first end with the first connection area being located between the two panes and the second end with the second connection area between the two panes leading out of the composite pane. In this case, the electrical conductor tracks in the first connection area are in electrical contact with the electrical functional element and are preferably galvanically connected to them.

The connection arrangement furthermore comprises one or preferably several electrical connection pieces, each selected from a plug or a socket and firmly connected to the ribbon cable in the second connection area. Each electrical connection piece is provided with a plurality of first electrical connection means, each of which is electrically connected to an electrical conductor track of the ribbon cable. The electrical connector is provided for mechanical plug-in connection with a mating connector, which is either a plug or a socket, the mating connector being a plug if the connector is a socket, and vice versa. The connection counterpart is provided with at least one second electrical connection means, which electrically contact the first electrical connection means of the connection piece when the plug connection is established. If the connecting piece and the connecting counterpart are plugged into one another, a positive and / or non-positive mechanical connection is formed between the connecting piece and the connecting counterpart. For such a plug-in connection, a plug-in opening is provided, for example, in the connection piece, which in this case is a beech tree into which the connection counterpart, designed as a plug, is inserted. Conversely, it is equally possible for the mating connection piece to have a plug-in opening, which in this case is a socket into which the connection piece designed as a plug is inserted. Both the socket and the plug are electrical components that each have a housing.

The ribbon cable according to the invention can have one or more conductor tracks. The plurality of conductor tracks can be arranged next to one another or in several planes one above the other or a combination thereof.

The connection arrangement according to the invention advantageously enables a flexible, inexpensive and simple electrical connection of the ribbon cable to an electrical device outside the composite pane, preferably an electrical control system for controlling the electrical functional element of the composite pane, thanks to the connecting pieces attached to the ribbon cable. The connecting pieces serve, as it were, as adapters for a large number of applications and customer-specific requirements, the electrical connection of the electrical functional element being able to be implemented by simply producing a respective mechanical plug connection between the connecting piece and the counterpart connecting piece. In a particularly advantageous manner, a simple electrical connection of the ribbon cable to a further connection cable, in particular a round cable, is possible in this way. Expensive soldered connections for making electrical contact with the connection cable, which have to be sheathed for electrical insulation, can advantageously be dispensed with.

Conventional, commercially available, electrical housing components can be used for the plug and socket used as the connecting piece and the counterpart connecting piece, the electrical connection means being designed, for example, in the form of pins and sockets. When the plug connection is formed between the plug and socket, the plug pins come into electrical contact with the electrical sockets. For example, the connection piece is the socket and has a plug-in opening for the counterpart connection and is equipped, for example, with plug-in pins which are each in electrical connection with a conductor track of the ribbon cable.

As already stated, the connecting piece and the counterpart connecting piece are each housing components with a housing in which the electrical connection means are located. According to an advantageous embodiment of the connection arrangement according to the invention, the connecting pieces are each surrounded by a further protective housing for their mechanical protection. In this case, it is possible that if there are several connecting pieces, the connecting pieces are each surrounded by an individual protective housing. It is also possible, however, for the connecting pieces to be surrounded by a common protective housing, i.e. the connecting pieces are jointly surrounded by a single protective housing. Several protective housings can have the advantage of better handling during manufacture, whereas the design as a single protective housing can be more cost-effective. The protective housing increases the mechanical stability of the connecting pieces, in particular during the manufacture of the connection arrangement, and thus reduces the number of defective items that are rejected, which in turn corresponds to cost savings. The at least one protective housing is arranged in such a way that it comes to lie over the one or more connecting pieces and is preferably modeled on the outer shape of the connecting pieces. It is thus possible to achieve a form-fitting housing for the one or more connecting pieces.

The at least one protective housing is used to mechanically protect the connecting pieces and is advantageously designed in such a way that it counteracts any deformations of the connecting pieces during the production of the connection arrangement, in particular when laminating the composite panes under vacuum and at high temperatures. The protective housing can contain or consist of a suitably strong plastic, for example polyimide (PI), preferably in connection with glass fibers, or PBTGF10, PA6GF25, PA66GF30, PA, PA6 or PA66. For this purpose, the at least one protective housing is particularly advantageously made of a material that is harder than the material from which the connecting pieces are made. The material hardness is determined according to the known common methods, for example in accordance with ISO 14577, as it was used at the time of registration or at the time of priority.

The protective housing can be produced, for example, by injection molding or 3D printing. For example, the protective housing can be glued to the one or more connecting pieces. However, joint production with the one or more connecting pieces is also possible, for example using the injection molding process.

If the connecting pieces each have a plug-in opening for plugging in the connecting counter-piece, the protective housing saves the plug-in opening, and good mechanical protection of the connecting pieces can nevertheless be achieved.

The protective housing is preferably arranged essentially on one side of the connecting piece, with it extending on the three sides facing away from the opening as far as the flat ribbon cable or at the same height.

The maximum height of the protective housing is preferably less than 30 mm and in particular from 7 mm to 20 mm.

The protective housing advantageously has wedge-shaped rises on the three sides facing away from the opening, so that there are no sharp edges there.

The at least one protective housing can advantageously be used to fasten the one or more connecting pieces to the ribbon cable, for example by gluing.

According to a particularly advantageous embodiment of the connection arrangement according to the invention, a plurality of connection pieces are arranged in a row next to one another on the second connection area of the ribbon cable. On the one hand, this simplifies the production of the ribbon cable with connecting pieces and the formation of the plug connections with the connecting counterparts. On the other hand, the connecting pieces arranged next to one another can be encapsulated in a particularly simple manner by a common (single) protective housing.

According to one embodiment of the connection arrangement according to the invention, the connection piece or pieces are each designed so that a plug-in direction for forming the plug-in connection between the connection piece and the counterpart connection is the same as a direction of extension of the ribbon cable in the second connection area. In relation to the direction of extension of the ribbon cable towards the second end, the plug-in direction is the same or opposite. This configuration therefore corresponds to a “straight” configuration, which can also be referred to as a T configuration, if the connecting pieces lead to a widening of the ribbon cable. For example, a connection cable, in particular a round cable, which is electrically connected to the ribbon cable, runs in the same direction as the ribbon cable, so there is no change in direction in the cable route due to the electrical plug connection. However, it is also possible for the connection cable to run in opposite directions parallel to the ribbon cable. In this case, the course of the connection cable is rotated by 180 ° by the electrical plug connection compared to the course of the ribbon cable, the direction of the cable course is thus inverted. If the connecting pieces are each provided with a plug-in opening for plugging in the counterpart, the plug-in opening has an orientation that is the same as the direction of extension of the ribbon cable in the second connection area (in relation to a direction towards the second end: same or opposite).

According to an alternative embodiment of the connection arrangement according to the invention, it is also possible that a plug-in direction for forming the plug-in connection between the connection piece and the counterpart connection is different from a direction of extension of the ribbon cable in the second connection area. An angle between the plug-in direction to form the plug connection and the extension direction of the ribbon cable (for example, based on a direction towards the second end) is advantageously in the range between greater than 0 ° and less than 180 ° degrees and is in particular 90 °. This refinement can also be referred to as an L configuration if the course of a connection cable connected to the ribbon cable, in particular a round cable, is rotated by 90 ° relative to the course of the ribbon cable. If the connecting pieces are each provided with a plug-in opening for plugging in the counterpart, the plug-in opening has an orientation that is different from the direction of extension of the ribbon cable in the second connection area or one of Has zero different angles in the range between greater than 0 ° and less than 180 ° degrees.

In an advantageous embodiment of the invention, the opening of the electrical connection piece is through an adhesive strip, for example through a polymer film, which has an adhesive surface on one side. Alternatively, the opening of the electrical connector can be closed by a stopper, preferably a stopper made of silicone. Both protect the inside of the connector (i.e. the plug or the socket) from contamination, which would be further process steps, storage or transport.

In general, the ribbon cable is a flat body with two opposite sides, which can optionally be brought into a flat or curved shape. In the flat (i.e. not curved) state, the flat conductor is arranged in one plane. The ribbon cable is generally elongated and has two ends along its direction of extension.

An advantageous embodiment of a ribbon cable according to the invention comprises at least two electrical conductor tracks, the electrical conductor tracks being arranged at least in sections next to one another or one above the other.

In a further advantageous embodiment of the invention, at least two of the electrical conductor tracks within the ribbon cable are arranged one above the other in at least two, preferably in exactly two or exactly three or exactly four planes (with respect to the plane of extension of the ribbon cable).

The ribbon cable according to the invention comprises at least two electrical conductor paths, the at least two of the electrical conductor paths within the ribbon cable being arranged one above the other in at least two, preferably in exactly two or exactly three or exactly four levels. One above the other means here with regard to the plane of extension of the ribbon cable, i.e. with regard to the plane that is spanned by the two larger dimensions of the ribbon cable. Advantageously, in each case at least two conductor tracks are arranged congruently in the projection orthogonally to the plane of extent. Alternatively, the conductor track can also be made larger in one plane and essentially occupy the plane within the ribbon cable, preferably less an insulating edge area, partially or completely. This increases the current-carrying capacity of this conductor track.

In an advantageous embodiment of a ribbon cable according to the invention, at least one electrical conductor track is arranged on a first surface of an electrically insulating carrier film and at least one further conductor track is arranged on the second surface (i.e. the surface opposite the first surface with respect to the carrier film) of the carrier film.

In a further advantageous embodiment of a ribbon cable according to the invention, the electrical conductor tracks are firmly connected to the first or second surface of the carrier film, preferably via an adhesive surface. Alternatively, the carrier film can be coated with the electrical conductor tracks, in particular using a printing process, for example a screen printing process.

In a further advantageous embodiment of a ribbon cable according to the invention, the ribbon cable has insulating areas, preferably consisting of sections of an insulating film, between the conductor tracks of a plane. Sections of an insulating film are also advantageously arranged at the edge of the ribbon conductor.

In a further advantageous embodiment of a ribbon cable according to the invention, the conductor tracks have at least one electrically insulating cover film on their surfaces facing away from the carrier film. The conductor tracks or the sections of an insulation film are preferably firmly connected to the cover film, for example via adhesive surfaces. The carrier film and the cover film together form an insulating sleeve which surrounds the electrical conductor tracks.

The width of the ribbon cable can be constant or vary. In particular, the ribbon cable can be widened in the first connection area and / or the second connection area.

In a further advantageous embodiment of a ribbon cable according to the invention, the maximum width is bF of the ribbon cable, preferably within the composite pane and / or at the exit point from the composite pane, from 6 mm to 40 mm, preferably from 20 mm to 40 mm and in particular from 25 mm to 30 mm. In a further advantageous embodiment of a ribbon cable according to the invention, the maximum thickness is dF of the ribbon cable, preferably within the composite pane and / or at the exit point from the composite pane, from 150 μm to 600 μm, preferably from 300 μm to 400 μm and in particular from 300 μm to 350 μm. Ribbon cables with such maximum dimensions, in particular within the laminated pane and / or at the point of exit from the laminated pane, can be made particularly effective laminating or impairing the stability of the composite pane or disrupting its visual appearance.

In an advantageous embodiment of the ribbon cable, it has a length of 5 cm to 150 cm, preferably 10 cm to 100 cm and in particular 50 cm to 90 cm. It goes without saying that the length, width and thickness of the ribbon cable can be adapted to the requirements of the respective individual case. The direction of the length defines the extension direction of the ribbon cable.

The carrier film, the cover film and / or the insulation film preferably contain polyimide or polyester, particularly preferably polyethylene terephthalate (PET) or polyethylene naphthalate (PEN), or consist thereof. The cover film and / or the insulation film can also consist of an electrically insulating lacquer, preferably a polymer lacquer. The cover film and / or the insulation film can also contain or consist of thermoplastics and elastomers such as polyamide, polyoxymethylene, polybutylene terephthalate or ethylene-propylene-diene rubber. Alternatively, potting materials such as acrylate or epoxy resin systems can be used as the cover film and / or insulation film.

The carrier film, the cover film and / or the insulating film preferably have a thickness of 10 μm to 300 μm, particularly preferably 25 μm to 200 μm and in particular 60 μm to 150 μm. The carrier film, the cover film and / or the insulation film are glued to the conductor tracks, for example via an adhesive layer. The thickness of the adhesive layer is, for example, from 10 μm to 150 μm and particularly preferably from 50 μm to 75 μm. Such carrier films, cover films and / or insulation films are particularly suitable for electrically insulating and mechanically stabilizing the conductor tracks and protecting them from mechanical damage and corrosion.

The electrical conductor tracks of the ribbon cable contain or consist preferably of a metallic material, for example copper, aluminum, stainless steel, tin, gold, silver or alloys thereof. If the electrical conductor tracks are produced as strips from a metal foil, the metal can be tinned in sections or completely. This is particularly advantageous in order to achieve good solderability with simultaneous corrosion protection. In addition, the contact with an electrically conductive adhesive is improved.

According to one embodiment, the electrical conductor tracks have a thickness dL from 10 µm to 300 µm, preferably from 30 µm to 250 µm and in particular from 50 µm to 150 µm. Such thin conductors are particularly flexible and can, for example, be easily laminated into composite panes and guided out of them. According to one embodiment, the electrical conductor tracks have a width bL from 0.05 mm to 40 mm, preferably from 1 mm to 20 mm and in particular from 2 mm to 5 mm. Such widths are particularly suitable in connection with the above-mentioned thicknesses to achieve sufficient current-carrying capacity.

Such ribbon cables are so thin that they can be embedded between the individual panes in the thermoplastic intermediate layer of a composite pane and led out of it without difficulty. The ribbon cable is therefore particularly suitable for contacting electrical functional elements in composite panes.

Each electrical conductor track can be electrically contacted at two contact points spaced apart from one another along the conductor track. The contact points are areas of the conductor tracks where electrical contact is possible. In the simplest embodiment, these are accessible areas of the electrical conductor tracks. The first connection area has a contact point of at least one of the electrical conductor tracks. The second connection area is typically, but not necessarily, on the same side as the first connection area of the ribbon cable. The at least one second connection area has a contact point of at least one of the electrical conductor tracks. The connection areas of the ribbon cable are used to make electrical contact with the conductor tracks, for which purpose any cover film and possibly insulation film or carrier film is not present or removed at least at the contact points, so that the conductor tracks are accessible.

It goes without saying that the connection areas can be protected from corrosion by an electrically conductive coating, such as tin-plating, or an electrically non-conductive layer, such as solder lacquer. This protective layer is usually not removed, burned or otherwise penetrated until the electrical contact is made, in order to enable electrical contact. Isolation-free connection areas can be produced by window techniques during production or by subsequent removal, for example by laser ablation or mechanical ablation. In window technology, the conductor tracks are coated on a carrier film by a cover film with corresponding recesses (windows) in the connection areas, for example glued or laminated. Alternatively, the conductor tracks are laminated on both sides, with a cover film in the corresponding recesses Has connection areas. In the case of subsequent removal, corresponding recesses can be made in the connection areas in the cover film if the conductor tracks have been applied to a carrier film. In the case of laminated ribbon cables, recesses can be made in the connection areas in a cover film and, if necessary, the carrier film. However, it is also possible that the ribbon cable in the first connection area and in the second connection area each have one or more openings in the cover film and possibly the carrier film. Each opening extends completely onto the conductor track, ie it forms a material-free passage on the conductor track.

The connection areas are designed according to their respective use. In an advantageous embodiment, the contact points are designed as solder contact points. The electrical line connection between the connection areas of the ribbon cable and the electrical functional element and the at least one connecting piece is preferably made by soldering, bonding, welding, clamping, squeezing or plugging. When soldering, soft soldering with a low-melting solder is preferred. Alternatively, the electrically conductive connection can be made by gluing with an electrically conductive adhesive or clamps, for example by means of a metallic clamp, sleeve or plug connection. In the interior of the composite pane, the electrical line connection can also be made by direct contact with the electrically conductive areas, this arrangement being firmly laminated into the composite pane and thus secured against slipping.

In the first or second connection area, the ribbon cable is advantageously provided with an electrode field which comprises a multiplicity of individual electrodes which are electrically connected to the conductor tracks. This enables simple electrical contacting of the electrical functional element for its specific control / regulation.

In an advantageous embodiment of a connection arrangement according to the invention, the ribbon cable in the second connection area comprises one or preferably several electrical connection pieces in which the ribbon cable is detachably or permanently connected to a connection cable.

In the counterpart connection, the electrically forwarded conductor tracks of the second connection area are advantageously electrically connected to electrical wires of one or more connection cables, in particular round cables.

The connection cables can in turn have electrical connection means, such as further plugs or sockets, at their end facing away from the connection counterpart, which make the connection arrangement connectable to board electronics or other control and evaluation units.

The connection arrangement according to the invention is preferably suitable for contacting glazing with electrical and / or active, and preferably electrically controllable, functional elements (active glazing for short), such as electrically heatable glazing, electrochromic glazing, glazing with SPD or PDLC films, illuminable glazing, for example with LED elements, solar or photovoltaic glazing, antenna panels or the like. It goes without saying that glazing can also have several of the named active functional elements.

The connection arrangement according to the invention advantageously comprises a composite pane with an electrical functional element which is arranged in the interior of the composite pane. The electrical functional element can be any electrical structure that fulfills an electrical function and requires control / regulation by external control electronics, so that the use of a ribbon cable with a plurality of conductor tracks is technically sensible.

The electrical functional element is preferably an advantageously large-area, electrically conductive layer that is advantageously transparent to visible light (electrical functional layer), as described at the beginning. The electrical functional layer or a carrier film with the electrical functional layer can be arranged on a surface of a single pane. For example, the electrical functional layer is located on an inner surface of the one and / or the other pane. Alternatively, the electrical functional layer can be embedded between two thermoplastic films of the intermediate layer. The electrical functional layer is then preferably applied to a carrier film or carrier disk. The carrier film or carrier disk preferably contains a polymer, in particular polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), polyethylene terephthalate (PET) or combinations thereof.

The electrical functional layer is preferably arranged on a surface of at least one pane and covers or covers the surface of the pane in part, but preferably over a large area. The expression “over a large area” means that at least 50%, at least 60%, at least 70%, at least 75% or preferably at least 90% of the surface of the pane is covered by the functional layer. The functional layer can, however, also extend over smaller portions of the surface of the pane. The functional layer is preferably transparent to visible light. In an advantageous embodiment, the functional layer is an individual layer or a layer structure made up of several individual layers with a total thickness of less than or equal to 2 μm, particularly preferably less than or equal to 1 μm.

In the context of the present invention, “transparent” means that the total transmission of the glazing complies with the statutory provisions for windshields and front side windows and preferably has a permeability of more than 70% and in particular more than 75% for visible light. For rear side windows and rear windows, “transparent” can also mean 10% to 70% light transmission. Correspondingly, “opaque” means a light transmission of less than 15%, preferably less than 5%, in particular 0%.

For example, the electrical functional layer contains at least one metal, preferably silver, nickel, chromium, niobium, tin, titanium, copper, palladium, zinc, gold, cadmium, aluminum, silicon, tungsten or alloys thereof, and / or at least one metal oxide layer, preferably tin -doped indium oxide (ITO), aluminum-doped zinc oxide (AZO), fluorine-doped tin oxide (FTO, SnO2: F) or antimony-doped tin oxide (ATO, SnO2: Sb). Transparent, electrically conductive layers are made, for example DE 20 2008 017 611 U1 and EP 0 847 965 B1 known. They consist, for example, of a metal layer such as a silver layer or a layer of a metal alloy containing silver. Typical silver layers preferably have thicknesses of 5 nm to 15 nm, particularly preferably 8 nm to 12 nm. The metal layer can be embedded between at least two layers of dielectric material of the metal oxide type. The metal oxide preferably contains zinc oxide, tin oxide, indium oxide, titanium oxide, silicon oxide, aluminum oxide or the like and combinations of one or more thereof. The dielectric material can also include silicon nitride, silicon carbide, aluminum nitride, and combinations of one or more thereof. The layer structure is generally obtained through a sequence of deposition processes that are carried out using a vacuum process such as magnetic field-assisted cathode sputtering or chemical vapor deposition (CVD). Very fine metal layers, which in particular contain titanium or niobium, can also be provided on both sides of the silver layer. The lower metal layer serves as an adhesion and crystallization layer. The upper metal layer serves as a protective and getter layer to prevent the silver from changing during the further process steps.

Transparent, electrical functional layers preferably have a sheet resistance of 0.1 ohm / square to 200 ohm / square, particularly preferably from 1 ohm / square to 50 ohm / square and very particularly preferably from 1 ohm / square to 10 ohm / square.

The electrical functional layer is preferably an electrically heatable layer, by means of which the composite pane is provided with a heating function. Such heatable layers are known per se to the person skilled in the art. They typically contain one or more, for example two, three or four, electrically conductive layers. These layers contain or consist preferably of at least one metal, for example silver, gold, copper, nickel and / or chromium, or a metal alloy and preferably contain at least 90% by weight of the metal, in particular at least 99.9% by weight of the metal. Such layers have a particularly advantageous electrical conductivity with a simultaneous high transmission in the visible spectral range. The thickness of an individual layer is preferably from 5 nm to 50 nm, particularly preferably from 8 nm to 25 nm. With such a thickness, advantageously high transmission in the visible spectral range and particularly advantageous electrical conductivity are achieved.

The electrical functional element can equally preferably be an electro-optical component, such as, for example, an EC (electrochromic) element, an SPD element or a PDLC element, as described at the beginning. These are known per se to the person skilled in the art, so that they do not have to be explained in more detail. The electrical functional layer can also be a polymeric, electrically conductive layer, for example containing at least one conjugated polymer or a polymer provided with conductive particles.

Electro-optical components, such as SPD or PDLC elements, are commercially available as multilayer films, the active layer being arranged between two flat electrodes which are used to apply a voltage to control the active layer. As a rule, the two flat electrodes are arranged between two carrier films, typically made of PET. Commercially available multilayer films are also covered on both sides with a protective film made of polypropylene or polyethylene, which serves to protect the carrier films from soiling or scratching. During the manufacture of the composite pane, the electro-optical component is cut out of the multilayer film in the desired size and shape and placed between the films of an intermediate layer, by means of which two glass panes are laminated together to form the composite pane. A typical application is windshields with electrically adjustable sun visors, which for example DE 102013001334 A1 , DE 102005049081 B3 , DE 102005007427 A1 and DE 102007027296 A1 are known.

In the connection arrangement according to the invention, the electrical functional element is advantageously electrically connected to at least two bus bars through which a current can be fed. The bus bars are preferably arranged in the edge region of the electrical functional element. The length of the busbar is typically essentially the same as the length of the respective side edge of the electrical functional element, but it can also be somewhat larger or smaller. Two busbars are preferably arranged, in the edge area along two opposite side edges of the functional element. The width of the busbar is preferably from 2 mm to 30 mm, particularly preferably from 4 mm to 20 mm. The bus bars are typically each designed in the form of a strip, the longer of its dimensions being referred to as length and the shorter of its dimensions being referred to as width. Such bus bars are designed, for example, as a printed and burned-in conductive structure. The printed busbar contains at least one metal, preferably silver. The electrical conductivity is preferably realized via metal particles contained in the bus bar, particularly preferably via silver particles. The metal particles can be in an organic and / or inorganic matrix such as pastes or inks, preferably as a burned screen printing paste with glass frits. The layer thickness of the printed busbar is preferably from 5 μm to 40 μm, particularly preferably from 8 μm to 20 μm and very particularly preferably from 10 μm to 15 μm. Printed busbars with these thicknesses are technically easy to implement and have an advantageous current-carrying capacity. Alternatively, the bus bar can also be designed as a strip of an electrically conductive film. The busbar then contains, for example, at least aluminum, copper, tinned copper, gold, silver, zinc, tungsten and / or tin or alloys thereof. The strip preferably has a thickness of 10 μm to 500 μm, particularly preferably 30 μm to 300 μm. Bus bars made of electrically conductive foils with these thicknesses are technically easy to implement and have an advantageous current-carrying capacity. The strip can be connected in an electrically conductive manner to the electrically conductive structure, for example via a solder mass, via an electrically conductive adhesive or by direct application.

The composite pane of the connection arrangement according to the invention comprises a first pane and a second pane, which are preferably made from glass, particularly preferably from soda-lime glass, as is customary for window panes. The panes can, however, also be made from other types of glass, for example quartz glass, borosilicate glass or aluminosilicate glass, or from rigid, clear plastics, for example polycarbonate or polymethyl methacrylate. The panes can be clear or tinted or colored. If the composite pane is used as a windshield, it should have sufficient light transmission in the central viewing area, preferably at least 70% in the main viewing area A in accordance with ECE-R43. The first disk and the second disk can also be referred to as an outer and an inner disk.

The first pane, the second pane and / or the intermediate layer can have further suitable coatings known per se, for example anti-reflective coatings, non-stick coatings, anti-scratch coatings, photocatalytic coatings or sun protection coatings or low-E coatings.

The thickness of the first disk and the second disk can vary widely and thus be adapted to the requirements in the individual case. The first pane and the second pane advantageously have standard thicknesses of 0.7 mm to 25 mm, preferably from 1.4 mm to 2.5 mm for vehicle glass and preferably from 4 mm to 25 mm for furniture, appliances and buildings, in particular for electrical ones Radiator, on. The size of the disks can vary widely and depends on the size of the use according to the invention. The first and second panes have areas of 200 cm ² to 20 m ^{2, which are} common in vehicle construction and architecture, for example.

An exemplary method for producing a connection arrangement according to the invention comprises the following steps:

1. a) providing a ribbon cable with electrical conductor tracks, the ribbon cable having a first connection area at a first end and a second connection area at a second end,
2. b) Electrically conductive connection of the conductor tracks of the ribbon cable in the first connection area with an electrical functional element,
3. c) Electrically conductive connection of the conductor tracks of the ribbon cable in the second connection area with one or more connecting pieces selected from a plug or socket, the electrical connecting pieces each being intended for a plug connection with an electrical counterpart selected from a plug or socket,
4. d) Arranging the ribbon cable between two panes in such a way that the first connection area is between the two panes and the second connection area is led out between the two panes,
5. e) arranging a protective housing on or around the connecting piece (s),
6. f) Laminating the two panes via a thermoplastic intermediate layer according to steps a), b), c), d) and e).

Steps a), b), c), d) and e) can be carried out in any order.

According to one embodiment of the method according to the invention, after the two panes have been laminated, a plug connection is formed between a respective connection piece and a connection counterpart.

The connection of the two individual panes during lamination is preferably carried out under the action of heat, vacuum and / or pressure. Methods known per se for producing a composite pane can be used. For example, so-called autoclave processes can be carried out at an elevated pressure of about 10 bar to 15 bar and temperatures of 130 ° C. to 145 ° C. for about 2 hours. Vacuum bag or vacuum ring processes known per se work, for example, at around 200 mbar and 80 ° C to 110 ° C. The first disk, the thermoplastic intermediate layer and the second disk can also be pressed into a disk in a calender between at least one pair of rollers. Systems of this type are known for the production of panes and normally have at least one heating tunnel in front of a press shop. The temperature during the pressing process is, for example, from 40 ° C to 150 ° C. Combinations of calender and autoclave processes have proven particularly useful in practice. Alternatively, vacuum laminators can be used. These consist of one or more heatable and evacuable chambers in which the first pane and the second pane are laminated within, for example, about 60 minutes at reduced pressures of 0.01 mbar to 800 mbar and temperatures of 80 ° C to 170 ° C.

The protective housing according to the invention is particularly advantageous in order to protect the connecting pieces, selected from a plug or socket, from mechanical stress and possibly the effects of heat during the lamination process. The protective housing according to the invention is particularly advantageous for plugs or sockets with plastic housings.

The connection arrangement according to the invention can be used, for example, as building glazing or vehicle glazing, preferably as vehicle glazing, in particular as a windshield or roof window of a motor vehicle.

In particular, active glazing such as electrochromic glazing, PDLC, LED, solar or photovoltaic modules, antenna conductors, electrically heatable coatings or the like can be contacted.

The various embodiments of the invention can be implemented individually or in any combination. In particular, the features mentioned above and to be explained below can be used not only in the specified combinations, but also in other combinations or on their own, without departing from the scope of the present invention.

It will first refer to the 1 until 3 taken, wherein an overall with the reference number 1 designated connection arrangement is illustrated in a schematic manner.

1 shows a plan view of an overall with the reference number 2 designated composite pane in a view through the second pane at the top here 4th .

2 shows a section of the composite pane 2 in a plan view of the area in which the whole with the reference number 11 designated ribbon cable according to the invention from the side surface 2.1 the composite pane 2 is led out.

3 FIG. 13 shows a section of the connection arrangement from FIG 1 or. 2 in a detailed view of the side surface 2.1 , at the point (exit point 29 ) to which the ribbon cable 11 from the composite pane 2 is led out.

The connection arrangement 1 includes a composite pane 2 , which is designed here, for example, as a roof window of a motor vehicle. As in 3 shown schematically, comprises the composite pane 2 a first slice 3 , which serves as the outer pane, and a second pane 4th as an inner pane. The inner pane is the pane facing the vehicle interior, while the outer pane faces the vehicle surroundings. The surface of the outer pane facing the vehicle environment (first pane 3 ) is referred to as surface I, as is usual in vehicle glazing technology, and the surface of the inner pane facing the vehicle interior (second pane 4th ) is referred to as surface IV. The two discs 3 , 4th consist, for example, of soda-lime glass. The two discs 3 , 4th are through two thermoplastic intermediate layers 9 for example made of polyvinyl butyral (PVB), ethylene vinyl acetate (EVA) or polyurethane (PU) firmly bonded to one another.

The composite pane 2 is with an electrical functional element, which is likewise only shown schematically 10 provided that is between the two discs 3 , 4th is located. The electrical functional element 10 is here, for example, a PDLC element that is used, for example, as an electrically controllable sun or privacy screen. The PDLC element is formed by a commercially available PDLC multilayer film which is inserted into the intermediate layer 9 is stored. The intermediate layer 9 comprises for this purpose, for example, a total of three thermoplastic films (not shown) with a thickness of, for example, 0.38 mm made of PVB, a first thermoplastic film with the first pane 3 is connected, and a second thermoplastic film to the second pane 4th is connected, and wherein an intermediate thermoplastic frame film has a cutout in which the cut functional element 10 is inserted precisely. The third thermoplastic film thus forms a kind of passe-partout for the functional element 10 , which is encapsulated all around in thermoplastic material and thus protected. This embedding of the PDLC element in a composite pane 2 is well known to the person skilled in the art, so that a precise illustration is not necessary. As is also known to the person skilled in the art, the PDLC element generally comprises an active layer between two flat electrodes and two carrier foils. The active layer contains a polymer matrix with liquid crystals dispersed therein, which align themselves as a function of the electrical voltage S applied to the surface electrodes, whereby the optical properties can be regulated.

The functional element 10 is here, for example, divided into nine segments by isolation lines 10.1 divided. The segments 10.1 are designed in strips. The isolation lines between the segments 10.1 have, for example, a width of 40 µm (micrometers) to 50 µm. They can for example have been introduced into the prefabricated multilayer film by means of a laser.

In particular, the isolation lines separate the surface electrodes of the functional element 10 in strips isolated from one another, each with a separate electrical connection. So are the segments 10.1 switchable independently of each other.

The respective surface electrodes of the segments 10.1 are on one side each individually over sections of bus bars 28 (in 1 shown on the left) and on the opposite side via a common busbar 28 (in 1 shown on the right). To apply a voltage to the respective individual busbar sections of the new segments 10.1 and the one common busbar 28 Thus, for example, ten independent electrical line connections are required here.

The composite pane 1 also has a ribbon cable 11 on. The busbars 28 of the segments 10.1 of the functional element 10 are each for example via electrical conductor wires 27 with the ribbon cable 11 electrically connected. A secure electrically conductive connection is preferably achieved by soldering the connection.

The functional element 2 is a PDLC functional element that acts as an adjustable sun protection. Depending on the position of the sun, the driver or another vehicle occupant can use the PDLC Operate the functional element, for example, via a touch control element.

To control the nine independent segments 10.1 with a common opposite pole has the ribbon cable 11 for example ten electrical conductor tracks that are electrically isolated from one another 12th on.

4th shows the schematic cross section of an exemplary ribbon cable with ten conductor tracks electrically isolated from one another 12th . There are five conductor tracks each 12th , 12 'in two different levels E1 , E2 arranged one above the other. There are also five conductor tracks 12th with a first (upper) surface of a carrier film 24 and five more tracks 12 ' on a second (lower) surface of a carrier film 24 connected and for example via adhesive surfaces not shown here with the carrier film 24 glued.

The electrical conductor tracks 12th , 12 ' for example each have a thickness dL of 75 µm and a width bL of 3 mm and consist, for example, of a copper foil or of tinned copper.

Furthermore, the ribbon cable 11 two electrically insulating cover foils 25.1 on that on the top and on the bottom of the carrier film 24 are arranged and the conductor tracks 12th , 12 ' between carrier film 24 and cover sheet 25.1 lock in. This will create the conductor tracks 12th , 12 ' protected from mechanical damage, short circuits and corrosion.

In the example shown, there are also sections of an electrically insulating insulation film 25.2 between the conductor tracks 12th one level E1 , E2 and arranged at the edge areas to the outside. The insulation film 25.2 is for example by adhesive connections, not shown here, with the carrier film 24 and the cover foils 25.1 firmly connected.

The entire ribbon cable 11 points, for example, at the exit point 29 from the composite pane 2 out a maximum width bF of 26 mm and a maximum thickness dF of 315 µm. Such a ribbon cable 12th can still be easily inserted into the composite pane 2 laminate in.

It goes without saying that the ribbon cable 11 can be adapted to the particular circumstances of the actual use and can, for example, extend over three or four levels. Alternatively or in combination, more or fewer conductor tracks can be arranged next to one another per level.

As in the schematic insertion of 2 Illustrated is the ribbon cable 11 partially in the composite pane 2 laminated and between the two panes 3 , 4th from the composite pane 2 led out. In the 2 is the ribbon cable 11 around the side face 2.1 the second disc 4th passed around and on surface IV of the second disc 4th arranged. The second disc can do this 4th have a recess in the exit area, for example by a ground area (not shown here).

The ribbon cable 11 has a first connection area 6th and a second connection area 8th on, being along a direction of extension of the ribbon cable 11 the first connection area 6th at a first end 5 and the second connection area 8th at a second end 7th of the ribbon cable 11 condition. The ribbon cable 11 points in the first connection area 6th into an electrode field 13 with ten electrodes for electrical (eg galvanic) contacting of the functional element 10 on.

The ribbon cable 11 points at its second end 7th a second connection area 8th on. This is via a connector 14th in the form of a plug and a connection counterpart 15th in the form of a socket with a round cable 26th connected in such a way that, for example, the individual conductor tracks 12th , 12 ' each with individual cores of the round cable 26th are electrically contacted. On the connector 14th remote end of the round cable 26th can for example be a connection element 17th , for example a plug or a socket, can be arranged for further electrical connection, for example with board electronics.

The connector 14th and / or the connection element 17th are for example within a protective housing 19th arranged that the connector 14th and, if applicable, the connection element 17th protect against mechanical damage during the lamination process.

5 shows a schematic cross-sectional representation of an alternative ribbon cable according to the invention 11 . This essentially corresponds to the structure of the ribbon cable 11 after 4th , with the conductor tracks 12th only in one level E1 are arranged side by side.

6A shows a detail view of a ribbon cable according to the invention 11 with connector 14th in the form of a plug and a protective housing 19th .

6B shows a perspective view of the protective housing according to the invention 19th after 6A .

For clarity, shows 6C a perspective view of the ribbon cable according to the invention 11 with connector 14th without protective housing.

As in 6A shown covers the protective housing 19th the connector 14th and extends on three sides down to the ribbon cable 11 . There is the protective housing with the ribbon cable, for example 11 glued. Only the side with the opening 22nd is in the protective housing 19th excepted and enables the respective connection counterpart to be plugged in 15th .

7A shows a perspective view of a ribbon cable according to the invention 11 with connector 14th using the example of a plug and a protective housing according to the invention 19th . The opening 22nd the connector housing is in this example with an adhesive strip 20th sealed so that during production, storage and transportation of the connector assembly 1 no dirt can penetrate the connector housing.

7B shows a perspective view of a ribbon cable according to the invention 11 with connector 14th using the example of a plug and a protective housing according to the invention 19th . In this example the opening is 22nd of the connector housing with a closure element 21 , made of a silicone material, so that no dirt or moisture can penetrate the connector housing during production, storage and transport of the connection arrangement.

Both adhesive strips 20th and closure element 21 can be easily removed at the point of use. An electrical line connection can then be established between the connection piece (here plug) and a suitable connection counterpart (here socket).

It emerges from the above statements that the connection arrangement according to the invention advantageously offers protection for the connecting piece and thus the electrical connection.

Commercial connectors such as sockets or plugs are typically not stable enough to ensure a lamination process with mechanical pressure, high temperature, for example in an autoclave or a vacuum bag. The protective housing can remain on the connector after the lamination process or optionally be removed.

If the protective housing according to the invention remains on the connector, it permanently protects its electrically conductive components, for example against dust-polluted surroundings, moisture, water, etc.
