Description

Die Erfindung betrifft einen Steckverbinder für Abstandshalter-Hohlprofile von Isolierglasscheiben mit den Merkmalen im Oberbegriff des Hauptanspruches.The invention relates to a connector for spacer hollow profiles of insulating glass panes with the features in the preamble of the main claim.

Ein solcher Steckverbinder ist aus der EP 0 283 689 bekannt. Er ist als Stanz- und Biegeteil aus Stahlblech mit einem im wesentlichen U-förmigen Querschnitt mit einem von Mittelsteg und Seitenstegen umschlossenen Hohlraum ausgebildet und besitzt im Bereich der Verbindungsstelle mehrere federnde Anschläge, die beim Aufstecken der Hohlprofile verschwinden. Die Anschläge können wahlweise am Mittelsteg oder den Seitenstegen angeordnet sein und bestehen aus jeweils zwei unmittelbar benachbarten und gegeneinander gerichteten ausgebogenen federnden Rückhaltenasen. Diese Steckverbinder werden in den Hohlprofilen nur durch Klemmschluß über Rückhaltenasen gehalten. Diese Befestigungsmöglichkeit ist für manche Anwendungsfälle unzureichend.Such a connector is known from EP 0 283 689. It is designed as a stamped and bent part made of sheet steel with an essentially U-shaped cross-section with a cavity enclosed by the central web and side webs and has several resilient stops in the area of the connection point, which disappear when the hollow profiles are attached. The stops can optionally be arranged on the central web or the side webs and each consist of two immediately adjacent and mutually directed, spring-loaded retaining lugs. These connectors are held in the hollow profiles only by a clamping connection via retaining lugs. This fastening option is insufficient for some applications.

Ein anderer Steckverbinder ist aus EP 0 133 655 bekannt. Er ist als Gießteil ausgebildet und besitzt dreieckige Mulden in seinem Mittelsteg. Diese dienen zum formschlüssigem Eingriff mit Wandverformungen im Abstandshalter-Hohlprofil. Ein solcher Steckverbinder ist als Gießteil aus Kunststoff, Zink order dgl. relativ teuer. Ungünstig ist außerdem der gesteigerte Materialaufwand, der durch die hohe Mittelstegdicke bedingt ist, die zur Einformung der Muldenöffnungen erforderlich ist. Ferner sind für die plastische Verformung und Stauchung der Hohlprofilwand sehr hohe Druckkräfte erforderlich. Die Muldenform erlaubt durch ihre beschränkte Tiefe und die schrägen Wände auch keine optimale Wandverformung der Hohlprofile und keinen optimalen Formschluß. Von Nachteil ist ferner, daß der vorbekannte Steckverbinder eine vorstehende Rippe als Anschlag für die aufgesteckten Hohlprofile aufweist, die an der Verbindungsstelle die Hohlprofile in unerwünschter Weise voneinander distanziert.Another connector is known from EP 0 133 655. It is designed as a cast part and has triangular hollows in its central web. These are used for positive engagement with wall deformations in the spacer hollow profile. Such a connector is relatively expensive as a cast part made of plastic, zinc or the like. In addition, the increased cost of materials, which is caused by the high central web thickness, which is necessary for forming the trough openings, is disadvantageous. Furthermore, are very important for the plastic deformation and compression of the hollow profile wall high pressure forces required. Due to its limited depth and the sloping walls, the trough shape also does not allow optimal wall deformation of the hollow profiles and optimal form fit. A further disadvantage is that the known connector has a protruding rib as a stop for the attached hollow profiles, which undesirably distances the hollow profiles from one another at the connection point.

Ein weiterer Steckverbinder in üblicher Bauweise ist beispielsweise auch aus der DE-OS 34 08 600 bekannt.Another connector in a conventional design is also known for example from DE-OS 34 08 600.

Der Erfindung liegt daher die Aufgabe zugrunde, einen wirtschaftlicheren Steckverbinder bzw. eine Steckverbindung aufzuzeigen, die eine bessere Befestigungsmöglichkeit bieten.The invention is therefore based on the object of demonstrating a more economical plug connector or a plug connection which offers a better fastening possibility.

Die Erfindung löst diese Aufgabe mit den Merkmalen im Hauptanspruch.
Der erfindungsgemäße Steckverbinder ist als Stanz- und Biegeteil aus Stahlblech hergestellt und damit kostengünstiger als ein Gußverbinder. Beim erfindungsgemäßen Steckverbinder sind die Öffnungen im Mittelsteg als freigestanzte Wanddurchbrüche ausgebildet. In diese Wanddurchbrüche kann die Deckwand eines aufgesteckten Hohlprofils verformt werden, so daß eine formschlüssige Verbindung mit hoher Rückhaltekraft gegen unerwünschtes Ausziehen des Steckverbinders aus dem Hohlprofil entsteht. In Variation zu einer Wandverformung kann die Steckverbindung auch durch Niete oder dergleichen andere eingesetzte Rückhalteelemente gesichert werden.The invention solves this problem with the features in the main claim.
The connector according to the invention is manufactured as a stamped and bent part from sheet steel and is therefore less expensive than a cast connector. In the connector according to the invention, the openings in the central web are designed as punched-out wall openings. The top wall of a plugged-on hollow profile can be deformed into these wall openings so that a positive connection with high retention force against undesired pulling out of the connector from the hollow profile is produced. In variation to a wall deformation, the plug connection can also be secured by rivets or the like other retention elements used.

Die als Wanddurchbruch gebildete Durchgangsöffnung hat besondere Vorteile hinsichtlich der Befestigungssicherheit. Zum einen läßt sich eine Wandverformung im Hohlprofil beliebig tief ausprägen, da sie durch die Durchgangsöffnung hindurchgreift. Sie ist damit in ihrer Tiefe nicht beschränkt, wie das bei der vorbekannten muldenförmigen Öffnung der Fall ist. Die Wandverformung läßt sich auch auf der vollen Fläche durch die Durchgangsöffnung pressen, so daß eine allseits dichte und feste Anlage erfolgt, die die Verbundsicherheit erhöht. Der dünnwandige Mittelsteg eines als Stanz- und Biegeteil ausgebildeten Steckverbinders hat außerdem den Vorteil, daß er sich gegenüber einer Auszugsbewegung des Steckverbinders besonders gut sperrt und eher in die Wandverformung des Hohlprofils einschneidet. Bei einer muldenförmigen Ausnehmung könnte es wegen der schrägen Muldenwände eventuell zu einem Abgleiten an der ebenfalls schrägen Wandverformung kommen.The through opening formed as a wall opening has particular advantages in terms of security. On the one hand, a wall deformation in the hollow profile can be shaped as deeply as it reaches through the through opening. It is therefore not limited in depth, as is the case with the previously known trough-shaped opening. The wall deformation can also be pressed over the full area through the through-opening, so that a tight and tight system is created which increases the bond security. The thin-walled central web of a connector designed as a stamped and bent part also has the advantage that it is particularly well locked against a pull-out movement of the connector and rather cuts into the wall deformation of the hollow profile. In the case of a trough-shaped recess, the sloping trough walls could possibly cause the sloping wall deformation to slide off.

Der erfindungsgemäße Steckverbinder weist Rückhaltenasen nur an den Seitenstegen auf. Sie dienen zur seitlichen Führung und als zusätzliche Auszugsperre. An der Verbindungsstelle der Hohlprofile, d.h. üblicherweise im Mittelbereich des Steckverbinders fungieren Rückhaltenasenpaare außerdem als Anschlag zur Begrenzung der Eindringtiefe beim Aufstecken der Hohlprofile. Von besonderem Vorteil ist dabei der Umstand, daß der Anschlag nur eine zeitweilige Funktion hat und keine Distanzierung der Hohlprofile bewirkt. Er verschwindet nämlich beim Aufstecken des zweiten Hohlprofils.
Der Mittelsteg ist glattwandig ausgebildet und besitzt vorzugsweise keine Rückhaltenasen.The connector according to the invention has retaining lugs only on the side webs. They serve for lateral guidance and as an additional pull-out lock. At the connection point of the hollow profiles, ie usually in the middle area of the connector, retaining lug pairs also act as a stop to limit the depth of penetration when the hollow profiles are attached. Of particular advantage is the fact that the stop only has a temporary function and does not cause the hollow profiles to be distanced. It disappears when the second hollow profile is attached.
The central web is smooth-walled and preferably has no retaining lugs.

Der erfindungsgemäße Steckverbinder ist in der bevorzugten Ausführungsform als Geradverbinder ausgebildet. In Variation kann er aber auch als Eckwinkel ausgeführt sein. Er eignet sich besonders für Abstandshalterrahmen von Isolierglasscheiben. Diese bestehen vorzugsweise aus Leichtmetall-Hohlprofilen, die üblicherweise durch Strangpressen hergestellt werden. Daneben können aber auch Hohlprofile aus anderen Metallen verwendet werden und solche, die auf andere Weise, beispielsweise durch Rollen, hergestellt sind. Der erfindungsgemäße Steckverbinder bzw. die Steckverbindung ist nicht auf Abstandhalterrahmen beschränkt, sondern kann auch für andere Arten und Anwendungsbereiche von Hohlprofilen erstreckt werden. In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen der Erfindung angegeben. Insbesondere können die Steckverbinder offene oder geschlossene Stirnseiten haben. Im Bereich der mittleren Querachse kann der Steckverbinder, insbesondere in der Ausführung als Geradverbinder auch eine Senkung zur Aufnahme einer Dichtungsmasse, eines Klebers oder dergleichen aufweisen.The connector according to the invention is designed in the preferred embodiment as a straight connector. In a variation, it can also be designed as a corner bracket. It is particularly suitable for spacer frames for insulating glass panes. These preferably consist of light metal hollow profiles, which are usually produced by extrusion. In addition, however, hollow profiles made of other metals can also be used and those made in a different way, for example by rolling. The connector according to the invention or the plug connection is not limited to spacer frames, but can also be extended for other types and areas of application of hollow profiles. Further advantageous refinements of the invention are specified in the subclaims. In particular, the plug connectors can have open or closed end faces. In the area of the central transverse axis, the connector, in particular in the version as a straight connector, can also have a counterbore for receiving a sealing compound, an adhesive or the like.

In Figuren 1 bis 4 ist jeweils ein Steckverbinder 1 in Draufsicht, Seitenansicht und Stirnansicht dargestellt, der als Geradverbinder für aufgesteckte Hohlprofile (5) von Abstandshalterrahmen für Isolierglasscheiben ausgebildet ist. In Variation kann der Steckverbinder (1) auch als Eckwinkel ausgeführt sein.In Figures 1 to 4, a connector 1 is shown in plan view, side view and end view, which is designed as a straight connector for attached hollow profiles (5) of spacer frames for insulating glass panes. In a variation, the connector (1) can also be designed as a corner bracket.

Wie Figur 1 verdeutlicht, besitzt der Steckverbinder (1) einen im wesentlichen U-förmigen Querschnitt mit einem Mittelsteg (2) und beidseitig daran anschließenden abgebogenen Seitenstegen (3). Der Steckverbinder (1) ist als dünnwandiges Stanz- und Biegeteil aus Stahlblech hergestellt und vergütet. Er besitzt eine Wandstärke von vorzugsweise ca. 0,5 mm.As illustrated in FIG. 1, the connector (1) has an essentially U-shaped cross section with a central web (2) and bent side webs (3) adjoining it on both sides. The connector (1) is manufactured and tempered as a thin-walled stamped and bent part made of sheet steel. It has a wall thickness of preferably approximately 0.5 mm.

Er ist mit seinem Querschnitt der Form der Hohlprofile (5) angepaßt und darin geführt. Im gezeigten Ausführungsbeispiel sind die Dachkanten des Hohlprofils (5) als angeschrägte Übergänge ausgebildet, wobei zwischen Mittelsteg (2) und Seitenstegen (3) des Steckverbinders (1) eine ähnliche Anschrägung vorhanden ist. In Abwandlung kann aber auch eine andere Querschnittsform, rechteckig, prismatisch, oval oder dergleichen gewählt werden.It is adapted with its cross section to the shape of the hollow profiles (5) and guided therein. In the exemplary embodiment shown, the roof edges of the hollow profile (5) are designed as beveled transitions, a similar bevel being present between the central web (2) and side webs (3) of the plug connector (1). Alternatively, a different cross-sectional shape, rectangular, prismatic, oval or the like, can be selected.

Der Steckverbinder (1) besitzt an den freiliegenden Rändern beider Seitenstege (3) mehrere seitlich und gegebenenfalls auch nach unten ausgebogene Rückhaltenasen (6). Diese sind durch eine Ausnehmung freigestanzt und weisen jeweils entgegen der Einsteckrichtung (15) des zugehörigen Hohlprofils (5). Alternativ können die Rückhaltenasen auch im mittleren Seitenstegbereich angeordnet sein.The connector (1) has a plurality of retaining lugs (6) that are bent out laterally and possibly also downward on the exposed edges of both side webs (3). These are punched out through a recess and each point against the insertion direction (15) of the associated hollow profile (5). Alternatively, the retaining lugs can also be arranged in the central side web area.

An der Verbindungsstelle (21) der beiden Hohlprofile (5), die vorzugsweise im Bereich der mittleren Querachse oder Mitte (4) des Steckverbinders (1) liegt, sind an beiden Seitenstegen (3) jeweils zwei federnde Rückhaltenasen (6) in unmittelbarer Nachbarschaft zueinander angeordnet und durch einen gemeinsamen T-förmigen Stanzschnitt freigelegt. Sie weisen gegeneinander und bilden dadurch einen Anschlag (7) für die von beiden Seiten aufgesteckten Hohlprofile (5). Der Steckverbinder (1) kann dadurch mit exakter Einstecktiefe in die Hohlprofile (5) eingeführt werden, was für die nachfolgend beschriebene formschlüssige Verbindung von Vorteil ist.At the connection point (21) of the two hollow profiles (5), which is preferably in the area of the central transverse axis or center (4) of the connector (1), there are two resilient retaining lugs (6) on both side webs (3) in the immediate vicinity of one another arranged and exposed by a common T-shaped die cut. They point against each other and thereby form a stop (7) for the hollow profiles (5) attached from both sides. The connector (1) can be inserted into the hollow profiles (5) with an exact insertion depth, which is advantageous for the positive connection described below.

Die als Anschlag (7) fungierenden Rückhaltenasen (6) sind als längliche Zungen ausgebildet und vorzugsweise nur zeitlich ausgebogen. Die anderen acht Rückhaltenasen (6) sind durch einen breiteren Stanzschnitt freigelegt, der eine Ausnehmung schafft. Die Rückhaltenasen (6) haben dadurch die Form von spitzen Ecken und sind schräg ausgebogen.The retaining lugs (6) functioning as stops (7) are designed as elongated tongues and are preferably only bent out over time. The other eight retaining tabs (6) are exposed through a wider punch cut that creates a recess. The retaining lugs (6) have the shape of pointed corners and are bent out obliquely.

Im Mittelsteg (2) des Steckverbinders (1) sind vier Wanddurchbrüche (8) angeordnet, die als im wesentlichen dreieckige Durchbrüche ausgestanzt sind. Sie sind auf der Längsachse (14) angeordnet und dabei paarweise symetrisch gegenüber der mittleren Querachse (4) verteilt. Die dreieckigen Wanddurchbrüche (8) weisen mit ihren Spitzen (9) paarweise zur jeweils nächstgelegenen Stirnseite (12).Four wall openings (8) are arranged in the central web (2) of the connector (1) and are punched out as essentially triangular openings. They are arranged on the longitudinal axis (14) and distributed symmetrically in pairs with respect to the central transverse axis (4). The triangular wall openings (8) point with their tips (9) in pairs to the nearest face (12).

Die Spitzen (9) zeigen damit jeweils auch in Einsteckrichtung (15) der zugehörigen Hohlprofile (5).The tips (9) thus also each point in the direction of insertion (15) of the associated hollow profiles (5).

Die Wanddurchbrüche (8) haben keine exakte Dreiecksform. Die Basis (10) schließt nicht direkt an die Flanken der Spitze (9) an, sondern ist etwas zurückversetzt. In Abweichung von der gezeigten Ausführungsform können die Wanddurchbrüche (8) auch in anderer Zahl und Anordnung vorgesehen sein. Es empfiehlt sich allerdings eine achssymetrische Verteilung bezüglich der Mitte (4). Die Dreiecksform kann ebenfalls abgewandelt werden. Es sollte allerdings die Spitze (9) mit ihrer Ausrichtung beibehalten werden.The wall openings (8) have no exact triangular shape. The base (10) does not connect directly to the flanks of the tip (9), but is set back somewhat. In a departure from the embodiment shown, the wall openings (8) can also be provided in a different number and arrangement. However, an axisymmetric distribution with respect to the center (4) is recommended. The triangular shape can also be modified. However, the tip (9) should be maintained with its orientation.

Die Erfindung betrifft neben der Gestaltung des Steckverbinders (1) auch die Steckverbindung mit den Hohlprofilen (5). Zur Befestigung des Steckverbinders (1) ist außer den Rückhaltenasen (6) auch noch eine formschlüssige Verbindung mit den aufgesteckten Hohlprofilen (5) vorgesehen.In addition to the design of the connector (1), the invention also relates to the connector with the hollow profiles (5). In addition to the retaining lugs (6), a positive connection with the attached hollow profiles (5) is also provided for fastening the connector (1).

Für die formschlüssige Verbindung gibt es mehrere Möglichkeiten.
Fig. 1 zeigt die erste Variante mit einer Nietverbindung. Der Mittelsteg (2) liegt plan und vorzugsweise vollflächig an der Dachwand (17) des Hohlprofils (5) an. Die Dachwand (17) weist vorzugsweise zur Rahmenaußenseite und besitzt mehrere durchgehende Ausnehmungen (20), die entsprechend der Wanddurchbrüche (8) im Steckverbinder (1) verteilt und angeordnet sind. Wenn der Steckverbinder (1) im Hohlprofil (5) steckt und mit dem Anschlag (7) an dessen Stirnwand anliegt, befinden sich die Wanddurchbrüche (8) und die Ausnehmungen (20) in der Dachwand (17) deckungsgleich übereinander.There are several options for the positive connection.
Fig. 1 shows the first variant with a riveted joint. The central web (2) lies flat and preferably over the entire surface of the roof wall (17) of the hollow profile (5). The roof wall (17) preferably faces the outside of the frame and has a plurality of continuous recesses (20) which are distributed and arranged in accordance with the wall openings (8) in the connector (1). If the connector (1) is in the hollow profile (5) and rests with the stop (7) on its end wall, the wall openings (8) and the recesses (20) in the roof wall (17) are congruent one above the other.

Mit dem Aufstecken des zweiten Hohlprofils (5) wird die als Anschlag (7) fungierende, federnde Rückhaltenase (6) zurückgebogen und verschwindet im Hohlprofil (5). Damit stoßen an der Verbindungsstelle (21) beide Hohlprofile (5) dicht und im wesentlichen fugenlos aneinander und sind auch beide mit ihren Ausnehmungen (20) gegenüber den Wanddurchbrüchen (8) im Steckverbinder exakt positioniert. Die Hohlprofile (5) können nacheinander oder gleichzeitig auf den Steckverbinder gesteckt werden.When the second hollow profile (5) is attached, the resilient retaining lug (6) acting as a stop (7) is bent back and disappears in the hollow profile (5). Thus, at the connection point (21), both hollow profiles (5) abut each other in a tight and essentially seamless manner and both are also exactly positioned with their recesses (20) in relation to the wall openings (8) in the connector. The hollow profiles (5) can be inserted one after the other or simultaneously on the connector.

Nach dem Zusammenfügen eines oder beider Hohlprofile (5) mit dem Steckverbinder (1) werden Niete (18) durch die Wandöffnungen (8,20) eingesetzt und angezogen. Die Niete (18) formen sich zumindest teilweise in die Spitzen (9) der Wanddurchbrüche (8). Durch die Spitzen (9) wird auch eine Keilwirkung erzielt, die die Hohlprofile (5) zur Verbindungsstelle (21) drängt und verspannt. Sie wirkt sich auch bei einer Auszugsbelastung des Steckverbinders (1) stabilisierend aus.After joining one or both hollow profiles (5) with the plug connector (1), rivets (18) are inserted and tightened through the wall openings (8, 20). The rivets (18) form at least partially in the tips (9) of the wall openings (8). The tips (9) also achieve a wedge effect, which urges and braces the hollow profiles (5) to the connection point (21). It also has a stabilizing effect when the connector (1) is pulled out.

Fig. 2 zeigt die zweite Variante der formschlüssigen Verbindung. Statt der Niete (18) greift hier eine Wandverformung (19) formschlüssig in und durch die Wanddurchbrüche (8). Sie befindet sich ebenfalls vorzugsweise an der Rahmenaußenseite. Die Wandverformung (19) wird durch Verstemmen mit entsprechenden Stempeln (nicht dargestellt) geschaffen, die die Dachwand (17) nach unten drücken und plastisch verformen. Durch die Anschläge (7) erfolgt in der vorbeschriebenen Weise auch hier eine exakte Positionierung des Steckverbinders (1) in den Hohlprofilen (5) und damit auch eine genaue Zuordnung der Wanddurchbrüche (8) zu den vorerwähnten Stempeln.Fig. 2 shows the second variant of the positive connection. Instead of the rivet (18) here a wall deformation (19) engages in a form-fitting manner in and through the wall openings (8). It is also preferably located on the outside of the frame. The wall deformation (19) is created by caulking with appropriate stamps (not shown) which press the roof wall (17) down and plastically deform it. Through the stops (7) in the manner described above, the connector (1) is precisely positioned in the hollow profiles (5) and thus also an exact assignment of the wall openings (8) to the aforementioned stamps.

Die Wandverformungen (19) werden vorzugsweise auf der vollen Fläche der Wanddurchbrüche (8) durchgepreßt, wobei die Stempel in ihrem Querschnitt vorzugsweise kreisrund gestaltet sind. Die Wandverformung (19) legt sich in vollem Umfang an die Ränder der Wanddurchbrüche (8), was für einen festen Formschluß sorgt. Die Wanddurchbrüche (8) sind durch einen geraden Schnitt freigestanzt und besitzen dünne, vertikale Kanten. Sie werden durch die Wandverformung (19) fest umgriffen.The wall deformations (19) are preferably pressed through on the full surface of the wall openings (8), the cross section of the stamps preferably being circular. The wall deformation (19) settles in full Circumference to the edges of the wall openings (8), which ensures a firm form fit. The wall openings (8) are punched out by a straight cut and have thin, vertical edges. They are firmly gripped by the wall deformation (19).

Fig. 2 zeigt auch eine Abwandlung in der Formgebung des Steckverbinders (1), der ansonsten der Ausführungsform von Figur 1 entspricht. Im Bereich der Mitte (4) ist eine querlaufende Senkung (11) vorgesehen. Diese wird durch eine Prägung und Absenkung des Mittelsteges bei der Herstellung geschaffen. Die Senkung (11) befindet sich an der Verbindungsstelle (21) der aufgesteckten Hohlprofile (5) und nimmt eine Dichtungsmasse, einen Kleber oder dergleichen (nicht dargestellt) auf. Die Wanddurchbrüche (8) schließen beidseits mit etwas Abstand an die Senkung (11) an.Fig. 2 also shows a modification in the shape of the connector (1), which otherwise corresponds to the embodiment of Figure 1. A transverse depression (11) is provided in the area of the center (4). This is created by embossing and lowering the center bar during manufacture. The depression (11) is located at the connection point (21) of the attached hollow profiles (5) and receives a sealing compound, an adhesive or the like (not shown). The wall openings (8) adjoin the countersink (11) on both sides with some clearance.

Im Ausführungsbeispiel der Figuren 1 und 2 ist der Steckverbinder (1) stirnseitig geschlossen. Der Mittelsteg (2) ist hierzu an beiden Enden unter Bildung einer schrägen Stirnabdeckung (13) nach unten abgebogen. Ein gerader Steckverbinder (1) wird in dieser Ausführungsform vorzugsweise so in den Hohlprofilen (5) montiert, daß sein Mittelsteg (2) zur Außenseite des Abstandshalterrahmens weist. Der im U-förmigen Steckverbinder (1) befindliche Hohlraum (16) weist dann zur Rahmeninnenseite und damit zur Innenfläche der Isolierglasscheibe. Der Abstandshalterrahmen und der Steckverbinder (1) sind mit einem Trocknungsmittel, vorzugsweise in Granulatform, gefüllt, das damit auch im Bereich des Steckverbinders (1) über Bohrungen in der Hohlprofilwand mit der Innenseite der Insolierglasscheibe in Verbindung steht.In the embodiment of Figures 1 and 2, the connector (1) is closed on the front. For this purpose, the central web (2) is bent downward at both ends to form an oblique end cover (13). In this embodiment, a straight connector (1) is preferably mounted in the hollow profiles (5) in such a way that its central web (2) faces the outside of the spacer frame. The cavity (16) located in the U-shaped connector (1) then faces the inside of the frame and thus the inner surface of the insulating glass pane. The spacer frame and the plug connector (1) are filled with a drying agent, preferably in granular form, which is thus also connected to the inside of the insulating glass pane in the area of the plug connector (1) via bores in the hollow profile wall.

Figuren 3 und 4 zeigen einen abgewandelten Steckverbinder (1), der stirnseitig offen ist. Ansonsten entsprechen die Steckverbinder (1) den Auführungsformen von Figuren 1 und 2. Der Mittelsteg (2) ist in Figuren 3 und 4 nur geringfügig abgesenkt und schafft dadurch eine stirnseitige Durchgangsöffnung. Der Hohlraum (16) des Steckverbinders (1) ist dadurch axial voll durchgängig. Dies ermöglicht ein Durchfließen des Trockungsmittels und ein Befüllen des Abstandshalterrahmens mit eingesteckten Steckverbindern (1).Figures 3 and 4 show a modified connector (1) which is open at the front. Otherwise, the plug connectors (1) correspond to the embodiments shown in FIGS. 1 and 2. The central web (2) is only slightly lowered in FIGS. 3 and 4 and thereby creates a through opening on the end face. The cavity (16) of the connector (1) is axially completely through. This enables the desiccant to flow through and the spacer frame to be filled with plug-in connectors (1).

Bei dieser Ausführungsform kann der Steckverbinder (1) vorzugsweise so in den Hohlprofilen (5) montiert sein, daß sein Mittelsteg (2) zur Rahmeninnenseite und zum Innenbereich der Isolierglasscheibe weist.In this embodiment, the connector (1) can preferably be mounted in the hollow profiles (5) in such a way that its central web (2) faces the inside of the frame and the inside of the insulating glass pane.
