Description

Die Erfindung betrifft einen Steckverbinder mit den Merkmalen im Oberbegriff des Hauptanspruchs.The invention relates to a connector having the features in the preamble of the main claim.

Ein solcher Steckverbinder ist aus der DE 20 2006 006 087 U1 bekannt. Er dient zur Verbindung von Hohlprofilen von Abstandshaltern oder Sprossen für Isolierglasscheiben und kann als Eckwinkel oder als Geradverbinder ausgebildet sein. Der Steckverbinder weist mindestens eine Mittelwand mit zentralen Durchgangsöffnungen und Seitenwände sowie ein oder mehrere Rückhalteelemente auf, die an den freien Rändern der Seitenwände angeordnet sind. Durch die zentralen Durchgangsöffnungen der Mittelwand können Klammern von außen durch die Hohlprofile und den Steckverbinder in gegenüber liegend angeordnete Endstopfen von Sprossen eingeschossen werden.Such a connector is from the DE 20 2006 006 087 U1 known. It is used to connect hollow profiles of spacers or rungs for insulating glass panes and can be designed as a corner or as a straight connector. The connector has at least one center wall with central through openings and side walls and one or more retaining elements which are arranged on the free edges of the side walls. By the central through holes of the middle wall brackets can be injected from the outside through the hollow sections and the connector in oppositely disposed end plugs of rungs.

Außerdem ist es aus der DE 297 22 771 U1 bekannt, massive Bodenteile oder Mittelwände mit Lamellen oder Federnasen als Rückhalteelemente auszurüsten, die in Rippen, Perforationsreihen oder dergleichen Erhebungen an der benachbarten Innenwand des Hohlprofils eingreifen. Die Böden oder Mittelwände des Steckverbinders sind für die Federaufnahme konkav gewölbt oder weisen vertiefte Kanäle auf.Besides, it is from the DE 297 22 771 U1 known to equip massive floor parts or middle walls with slats or spring lugs as retaining elements which engage in ribs, rows of perforations or the like elevations on the adjacent inner wall of the hollow profile. The bottoms or middle walls of the connector are concavely arched for the spring retainer or have recessed channels.

Es ist Aufgabe der vorliegenden Erfindung, einen verbesserten Steckverbinder aufzuzeigen, der universal verwendbar ist und der sich auch für den Einsatz von Klammern oder anderen Befestigungselementen für externe Anbauteile eignet.It is an object of the present invention to provide an improved connector that is universally applicable and also for the use of brackets or other fasteners for external attachments is suitable.

Die Erfindung löst diese Aufgabe mit den Merkmalen im Hauptanspruch.The invention solves this problem with the features in the main claim.

Der beanspruchte Steckverbinder hat eine oder mehrere Durchgangsöffnungen an mindestens einer Mittelwand, die einen Durchtritt von Klammern oder anderen Befestigungselementen erlauben. Die Durchtrittsöffnungen sind schmal ausgebildet und haben eine begrenzte Länge. Sie haben eine längliche Form und erstrecken sich mittig sowie in Längsrichtung des Verbinder. Dies ist für den Durchtritt und die Positionierung von Klammern oder dgl. von Vorteil. Ferner kann hierdurch die Mittelwand weitgehend massiv ausgebildet sein und dem Verbinder eine hohe Steifigkeit verleihen. Der beanspruchte Steckverbinder, insbesondere in Form eines Geradverbinders, verbindet durch diese Gestaltung eine hohe mechanische Stabilität mit einer Eignung für den zumindest weitgehend behinderungsfreien Durchlass von Klammern oder anderen Befestigungselementen.The claimed connector has one or more through openings on at least one center wall allowing passage of clips or other fasteners. The passages are narrow and have a limited length. They have an elongated shape and extend in the center and in the longitudinal direction of the connector. This is for the passage and the positioning of brackets or the like. Of advantage. Furthermore, this can make the middle wall largely solid and give the connector a high rigidity. The claimed connector, in particular in the form of a straight connector, connects by this design a high mechanical stability with a suitability for the at least largely disability-free passage of brackets or other fasteners.

Durch den kleinen Flächenbedarf der Durchgangsöffnung ist es möglich, an der Mittelwand zusätzlich Rückhalteelemente, beispielsweise ausgestellte Federnasen, anzubringen. Diese können auf eventuelle Perforationsreihen abgestimmt und entsprechend positioniert werden. Hierdurch lässt sich eine optimierte Rückhaltewirkung erreichen.Due to the small area requirement of the passage opening, it is possible to additionally attach retaining elements, for example flared spring lugs, to the middle wall. These can be matched to any perforation rows and positioned accordingly. As a result, an optimized retention effect can be achieved.

Der beanspruchte Steckverbinder ist besonders geeignet für sog. Warm-Edge-Profile von Abstandshaltern, die zum Teil aus Kunststoff bestehen können oder z.B. bei Edelstahlprofilen eine sehr geringe Wandstärke haben. Für derartige Verbindungen ist es günstig, wenn der Steckverbinder eine im wesentlichen Ω-förmigen Querschnitt aufweist. Über seitliche Ausbauchungen der abgewinkelten Seitenwände und die Ausbildung von Federbrücken ist eine optimierte Anpassung an die Hohlprofilform unter Aufnahme von deren Toleranzen sowie eine besonders gute Rückhaltewirkung erzielbar.The claimed connector is particularly suitable for so-called. Warm-edge profiles of spacers, which may be made partly of plastic or eg have a very small wall thickness in stainless steel profiles. For such compounds, it is advantageous if the connector has a substantially Ω-shaped Cross section has. About lateral bulges of the angled side walls and the formation of spring bridges is an optimized adaptation to the hollow profile shape receiving their tolerances and a particularly good retention effect achieved.

Eine eng benachbarte und angrenzende Anordnung der ein oder mehreren Rückhalteelemente an der Durchtrittsöffnung bietet fertigungstechnische Vorteile, insbesondere für Steckverbinder, die als Stanz- und Biegeteil aus Metall ausgebildet sind. Hierbei kann mit einem Stanzschnitt ein Freilegen der Durchtrittsöffnung und der bevorzugt mehreren paarweisen und beidseits der Durchtrittsöffnung angeordneten Rückhalteelemente nebst einem Ausbiegen dieser Rückhalteelemente erfolgen.A closely adjacent and adjacent arrangement of the one or more retaining elements at the passage opening offers manufacturing advantages, in particular for connectors which are formed as stamped and bent part made of metal. This can be done with a punched cut exposing the passage opening and preferably a plurality of pairs and on both sides of the passage opening arranged retaining elements together with a bending out of these retaining elements.

Die Erfindung betrifft einen Steckverbinder (1) für Hohlprofile (17,18) von Abstandshaltern oder Sprossen für Isolierglasscheiben. Die Erfindung betrifft ferner eine Anordnung von Hohlprofilen (17,18) mit einem eingesteckten Verbinder (1) und einem weiteren Anbauteil, welches mittels einer durch den Steckverbinder (1) hindurch geführten Klammer (19) oder eines anderen Befestigungselements fixiert ist.The invention relates to a connector (1) for hollow sections (17,18) of spacers or rungs for insulating glass panes. The invention further relates to an arrangement of hollow profiles (17,18) with an inserted connector (1) and a further attachment, which is fixed by means of a through the connector (1) guided through bracket (19) or other fastener.

Der Steckverbinder (1) kann wahlweise als Eckwinkel oder als Geradverbinder ausgebildet sein. In den gezeigten Ausführungsbeispielen ist ein Geradverbinder dargestellt. Dessen Merkmale lassen sich mit entsprechender Anpassung auch auf einen Eckwinkel übertragen.The connector (1) can optionally be designed as a corner or as a straight connector. In the embodiments shown, a straight connector is shown. Its features can also be transferred to a corner bracket with appropriate adaptation.

Wie Figur 7 verdeutlicht, dient der Steckverbinder (1) z.B. der Verbindung von zwei Hohlprofilen (17) eines Abstandshalterrahmens für eine Isolierglasscheibe. Die anderen Teile der Isolierglasscheibe sind der Übersicht halber nicht darstellt. Der Abstandshalterrahmen mit den Profilen (17) umgibt außenseitig im Ring einen innen liegenden hohlen Scheibeninnenraum (22). In diesem Scheibeninnenraum (22) können sich die vorerwähnten Anbauteile befinden, die z.B. als Hohlprofile (18), z.B. Sprossenprofile, als Endstopfen (20) oder dgl. ausgebildet sind und die am Abstandshalterrahmen und dessen Hohlprofilen (17) in geeigneter Weise durch ein oder mehrere Befestigungselemente (19) fixiert werden. Dies können z.B. im wesentlichen U-förmige Klammern sein, die von außen durch das Hohlprofil (17) und den Steckverbinder (1) in den Scheibeninnenraum (22) geführt werden und dort z.B. an einem aus Kunststoff bestehenden Endstück (20) eines Sprossenprofils (18) angreifen und dieses fixieren. Die Klammern oder Befestigungselemente (19) werden z.B. durch das Hohlprofil (17) und den Steckverbinder (1) mit Presslüft geschossen. Das Sprossenprofil (18) ist auf das Endstück (20) formschlüssig und außenseitig aufgesetzt und wird hierdurch im Scheibeninnenraum (22) geführt und mittels planer Anlage des an der Innenseite des Hohlprofils (17) fixierten Endstücks (20) gehalten.As FIG. 7 illustrates the connector (1), for example, the connection of two hollow sections (17) of a spacer frame for an insulating glass pane. The other parts of the insulating glass are not shown for clarity. The spacer frame with the profiles (17) surrounds the outside in the ring an inner hollow disc interior (22). In this disc interior (22), the above-mentioned attachments can be located, for example, as hollow sections (18), eg rung profiles, as end plugs (20) or the like. Formed and the spacer frame and its hollow sections (17) in a suitable manner by or a plurality of fastening elements (19) are fixed. This may be, for example, substantially U-shaped brackets which are guided from the outside through the hollow profile (17) and the connector (1) in the disc interior (22) and there eg on an existing plastic end piece (20) of a transom profile (18 ) attack and fix this. The clamps or fastening elements (19) are shot through the hollow profile (17) and the connector (1) with a press-release, for example. The rungs profile (18) is on the end piece (20) form-fitting and externally mounted and is thereby guided in the disk interior (22) and held by means of flat contact of the on the inside of the hollow profile (17) fixed end piece (20).

Der Steckverbinder (1) ist für den Durchlass von einem oder mehreren Befestigungselementen (19) in geeigneter Weise ausgebildet. Er weist in der gezeigten und bevorzugten Ausführungsform einen Ω-förmigen Querschnitt auf und hat seitliche Ausbauchungen (11). Figur 3 und 8 verdeutlichen diese Gestaltung. Aus Figur 8 ist außerdem ersichtlich, dass das Hohlprofil (17) eine entsprechende Hammerkopfform mit zwei seitlichen Ausbauchungen (11) am unteren und zum Scheibeninnenraum (22) weisenden Rand- oder Bodenbereich hat. Der Steckverbinder (1) ist an die Innenform des Hohlprofils (17) angepasst. Wenn das Hohlprofil (17) seinerseits ein Sprossenprofil ist, sieht die Querschnittsform des Steckverbinders (1) entsprechend anders aus. In weiterer Abwandlung der gezeigten und beschriebenen Ausführungsformen kann der Querschnitt des Steckverbinders (1) im wesentlichen U-förmig sein. Er kann auch eine geschlossene Kastenform haben.The connector (1) is designed for the passage of one or more fasteners (19) in a suitable manner. It has in the shown and preferred embodiment of an Ω-shaped cross-section and has lateral bulges (11). FIG. 3 and 8th illustrate this design. Out FIG. 8 is also apparent that the hollow profile (17) has a corresponding hammerhead shape with two lateral bulges (11) at the bottom and the disk interior (22) facing the edge or bottom area. The connector (1) is adapted to the inner shape of the hollow profile (17). If the hollow profile (17) in turn is a transom profile, the cross-sectional shape of the connector (1) looks accordingly different. In a further modification of the illustrated and described embodiments, the cross-section of the connector (1) may be substantially U-shaped. He can also have a closed box shape.

Der Steckverbinder (1) weist mindestens eine Mittelwand (2) und zwei beidseitig angrenzende Seitenwände (3) auf. Er hat außerdem mindestens ein Rückhalteelement (6,7,8), welches für einen mechanischen Rückhalt, z.B. durch eine gegen Auszug sperrende Verkrallung, im Hohlprofil (17) sorgt. In der gezeigten Ausführungsform besitzt der Steckverbinder (1) einen hohlen und axial durchgängig offenen Innenraum (14), durch den ein im Hohlprofil (17) befindliches Trocknungsmittel (nicht dargestellt) fließen kann. An den offenen Stirnseiten (15) können sich schräg aufgestellte Zungen (16) befinden, die von der Mittelwand (2) ausgehen.The connector (1) has at least one middle wall (2) and two side walls (3) adjoining on both sides. He also has at least one retaining element (6,7,8), which provides for a mechanical support, for example by an anti-extract locking claw in the hollow profile (17). In the embodiment shown, the connector (1) has a hollow and axially continuously open interior (14), through which a drying agent (not shown) located in the hollow profile (17) can flow. At the open end faces (15) can be located obliquely positioned tongues (16), which emanate from the middle wall (2).

In der gezeigten Ausführungsform wird der Steckverbinder (1) in das Hohlprofil (17) z.B. gemäß Figur 7 und 8 derart eingebaut, dass seine Mittelwand (2) ein Bodenteil bildet und zum Scheibeninnenraum (22) weist. Die Mittelwand (2) besitzt mindestens eine längliche und schmale Durchgangsöffnung (9) und mindestens ein abstehendes Rückhalteelement (7).In the embodiment shown, the connector (1) in the hollow profile (17), for example according to FIGS. 7 and 8 installed so that its center wall (2) forms a bottom part and facing the disc interior (22). The middle wall (2) has at least one elongate and narrow passage opening (9) and at least one protruding retaining element (7).

Die Durchgangsöffnung (9) erstreckt sich entlang der Längsachse (23) des Steckverbinders (1) und ist im Innenbereich der Mittelwand (2), vorzugsweise mittig, angeordnet. Die Ausrichtung der Durchgangsöffnung (9) kann exakt axial oder schräg mit einer überwiegenden axialen Richtungskomponente sein. Die Durchgangsöffnung (9) hat keine Abdeckung und erlaubt einen freien Durchtritt eines Befestigungselements (19).The passage opening (9) extends along the longitudinal axis (23) of the connector (1) and is in the interior of the central wall (2), preferably centrally located. The orientation of the passage opening (9) can be exactly axial or oblique with a predominant axial direction component. The passage opening (9) has no cover and allows a free passage of a fastener (19).

Das Rückhalteelement (7) ist neben der Durchgangsöffnung (9) und dabei vorzugsweise angrenzend angeordnet. Der innere Rand des Rückhalteelements (7) bildet einen Teil des Randes der Durchgangsöffnung (9). Vorzugsweise sind beidseits der Durchgangsöffnung (9) je zwei Rückhalteelemente (7) paarweise gegenüberliegend angeordnet. Im gezeigten Ausführungsbeispiel weist der Steckverbinder (1) beidseits einer quer liegenden Mittellinie (5) jeweils eine in Verbinderlängsrichtung (23) sich erstreckende Durchgangsöffnung mit zwei Paaren von Rückhalteelementen (7) auf.The retaining element (7) is arranged next to the passage opening (9) and preferably adjacent thereto. The inner edge of the retaining element (7) forms part of the edge of the passage opening (9). Preferably, two retaining elements (7) are arranged opposite one another in pairs on both sides of the passage opening (9). In the illustrated embodiment, the connector (1) on both sides of a transverse center line (5) in each case in a connector longitudinal direction (23) extending through opening with two pairs of retaining elements (7).

Die Rückhalteelemente (7) sind als ausgestellte Federnasen ausgebildet, die von der vorzugsweise ebenen Mittelwand (2) nach außen abgebogen sind und vom Verbinderboden in der Einbaustellung nach unten wegragen. Die Mittelwand (2) kann alternativ eine zum Innenraum (14) gerichtete und über ihre Breite sich erstreckende Wölbung aufweisen.The retaining elements (7) are designed as flared spring lugs, which are bent from the preferably flat central wall (2) to the outside and project away from the connector base in the installed position down. The middle wall (2) may alternatively have a curvature directed towards the interior space (14) and extending over its width.

Die Rückhalteelemente (7) sind im Bereich einer längslaufenden Perforation (21) des Hohlprofils (17) angeordnet. Figur 8 verdeutlicht diese Lage. Die schräg ausgestellten Federnasen (7) können am freien Ende einen schrägen Rand aufweisen. Sie können formschlüssig an den nach innen ragenden Perforationen (21) angreifen. Der gegenseitige Abstand der Rückhalteelemente (7) kann vom Teilungsmaß der Perforationen (21) abweichen, so dass mit Sicherheit eine Rückhaltenase (7) in formschlüssigen und klemmenden Eingriff mit einem Perforationsvorsprung kommt.The retaining elements (7) are arranged in the region of a longitudinal perforation (21) of the hollow profile (17). FIG. 8 clarifies this situation. The obliquely exposed spring lugs (7) may have an oblique edge at the free end. You can form-fitting attack on the inwardly projecting perforations (21). The mutual distance of the retaining elements (7) may differ from the pitch of the perforations (21), so that with certainty a retaining lug (7) comes in positive and clamping engagement with a Perforationsvorprung.

Die Durchgangsöffnung (9) weist eine Länge auf, die deutlich kleiner als die Schenkellänge des abgewinkelten oder geraden Steckverbinders (1) von der Mittellinie (5) bis zur benachbarten Stirnseite (15) ist. Die Öffnungslänge kann z.B. ca. zwei Drittel dieser Schenkellänge betragen. Die Breite der Durchgangsöffnung (9) ist wesentlich kleiner als die Breite der Mittelwand (2). Die Breite der bevorzugt in Querrichtung mittig angeordneten Durchgangsöffnungen (9) kann außerdem auf die den seitlichen Abstand von zwei Perforationsreihen (21) abgestimmt sein, an denen die Rückhalteelemente (7) angreifen. Die Öffnungsweite kann gleich oder kleiner als dieser Perforationsabstand sein.The passage opening (9) has a length which is significantly smaller than the leg length of the angled or straight connector (1) from the center line (5) to the adjacent end face (15). The opening length may e.g. about two-thirds of this leg length amount. The width of the passage opening (9) is substantially smaller than the width of the middle wall (2). The width of the through openings (9), which are preferably arranged centrally in the transverse direction, can also be matched to the lateral spacing of two rows of perforations (21) against which the retaining elements (7) engage. The opening width may be equal to or smaller than this perforation distance.

Die Rückhalteelemente (7) weisen eine Freimachung (10) in der Mittelwand(2) auf, die z.B. L-förmig ausgebildet ist und die sich zur Durchgangsöffnung (9) hin öffnet. Die Freimachung (10) wird von dem ausgestellten Rückhalteelement (7) zumindest teilweise abgedeckt. Die Durchgangsöffnung (9) und die beidseits angrenzenden Freimachungen (10) können ineinander übergehen. Die Breite der beidseits an die Öffnungsränder angrenzenden Rückhalteelemente (7) kann so gewählt sein, dass die Rückhalteelemente (10) in der Projektion innerhalb des Bereichs zwischen den freien Rändern der abgewinkelten Seitenwände (3) liegen. Figur 4 verdeutlicht diese Anordnung. Die schräg nach unten oder außen ausgestellten Federnasen weisen zu Rückhaltezwecken jeweils zur Mittellinie (5).The retaining elements (7) have a franking (10) in the middle wall (2), which is, for example, L-shaped and which opens towards the passage opening (9). The franking (10) is at least partially covered by the exhibited retaining element (7). The passage opening (9) and the two adjacent free spaces (10) can merge into each other. The width of the retaining elements (7) adjoining the opening edges on both sides may be selected so that the retaining elements (10) in the projection lie within the area between the free edges of the angled side walls (3). FIG. 4 clarifies this Arrangement. The obliquely downward or outward issued spring lugs have for retention purposes respectively to the center line (5).

Der Steckverbinder (1) kann aus einem beliebig geeigneten Material bestehen. In der gezeigten Ausführungsform besteht er aus Metall, insbesondere aus kalt gewalztem Stahl. Er kann alternativ aus einem anderen Material bestehen. Ferner sind Ausführungen aus Kunststoff oder aus einem anderen Werkstoff oder auch aus Verbundwerkstoffen möglich.The connector (1) may consist of any suitable material. In the embodiment shown it consists of metal, in particular of cold rolled steel. It can alternatively consist of a different material. Furthermore, versions made of plastic or of another material or of composite materials are possible.

In der gezeigten Ausführungsform ist der Steckverbinder (1) als Stanz- und Biegeteil ausgebildet. Die Durchgangsöffnungen (9) und die Freimachungen (10) werden aus der Platine in einem Stanzschnitt ausgeschnitten, wobei anschließend die Federnasen (7) abgebogen werden.In the illustrated embodiment, the connector (1) is formed as a punched and bent part. The passage openings (9) and the clearances (10) are cut out of the board in a punched cut, wherein subsequently the spring lugs (7) are bent.

Die ein oder zwei Durchgangsöffnungen (9) können auf die üblichen Maße der Klammern oder andern Befestigungselemente (19) abgestimmt sein. Die Klammern (19) können mit axialer Ausrichtung längs der Verbinderlängsachse gesetzt werden. Sie können auch schräg gesetzt werden. Außerdem können die Freimachungen (10) für den Durchtritt der Klammern (19) oder Befestigungselemente genutzt werden. Es kann außerdem genügen, wenn bei zweiarmigen Klammern (19) der dargestellten Ausführungsvariante nur ein Schenkel durch die Durchtrittsöffnung (9) und/oder eine Freimachung (10) verläuft und der andere Schenkel die Mittelwand (2) den massiven Bereich durchdringt.The one or two passage openings (9) can be matched to the usual dimensions of the clips or other fastening elements (19). The brackets (19) can be placed in axial alignment along the connector longitudinal axis. They can also be set at an angle. In addition, the clearances (10) for the passage of the brackets (19) or fasteners can be used. It may also be sufficient if, in the case of two-armed clamps (19) of the embodiment shown, only one limb extends through the passage opening (9) and / or one clearing (10) and the other limb penetrates the middle wall (2) through the solid region.

Bei der gezeigten Ω-Querschnittsform des Steckverbinders (1) sind die Seitenwände (3) mehrstufig abgewinkelt und bilden oberhalb der Ausbauchungen (11) einen hochstehenden Stegbereich mit einem freien Rand, der am Dach des Hohlprofils (17) angreift und als Rückhalteelement (8) einen oder mehrere in Wandverlängerung hochstehende Zähne aufweisen kann. Diese können untereinander in ihrer Höhe variieren. Sie können außerdem nach links und/oder rechts schräg ausgestellt bzw. gegenseitig verschränkt sein.In the shown Ω-cross-sectional shape of the connector (1), the side walls (3) are bent multi-level and form above the bulges (11) an upstanding web area with a free edge which engages the roof of the hollow profile (17) and as a retaining element (8) may have one or more upstanding in wall extension teeth. These can vary in height with each other. They can also be left-angled and / or right-angled or mutually interlaced.

Die Seitenwände (3) können im Bereich der Mittellinie (5) und der dort verlaufenden Verbindungsstelle der Hohlprofile (17) eine quer verlaufende Trennung (13) aufweisen, welche den besagten hochstehenden Steg mit dem freien Seitenwandrand durchtrennt und am unteren Stegende auch ein Stück zur Seite in Richtung der Ausbauchung (11) reicht. Derartige Trennungen (13) können in Abständen entlang der beiden Verbinderschenkel mehrfach vorhanden sein. Hierdurch werden Federbrücken (12) gebildet. Die durch die Trennungen (13) freigeschnittenen Seitenwandbereiche können in der Höhe bzw. vertikal und seitlich federn. Wie Figur 8 verdeutlicht, können außerdem die hochragenden Stege der Seitenwände (3) oberhalb der Ausbauchungen (11) schräg nach außen gestellt sein.The side walls (3) can in the region of the center line (5) and the connecting point of the hollow sections (17) extending there have a transverse separation (13), which cuts through the said upstanding web with the free side wall edge and at the lower end of the web also a piece to Side in the direction of the bulge (11) is enough. Such separations (13) may be multiple at intervals along the two connector legs. As a result, spring bridges (12) are formed. The side wall areas cut free by the separations (13) can spring vertically and laterally. As FIG. 8 clarifies, in addition, the towering webs of the side walls (3) above the bulges (11) can be placed obliquely outwards.

Die Federbrücken (12) können zumindest an einem Randbereich ein seitlich wirkendes Rückhalteelement (6) in Form einer schräg nach außen ausgestellten Federnase haben. Die Federnasen (6,8) drücken gegen die benachbarten Innenwände des Hohlprofils (17) und greifen z.B. am Übergang zwischen Dachbereich und Seitenwand sowie am darunter liegenden Seitenwandbereich des Hohlprofils (17) an. Figur 8 verdeutlicht diese Ausgestaltung. Die Federnasen (6) der Federbrücken (12) können gemäß Figur 2 unterschiedliche Höhenlagen haben und greifen dadurch an verschiedenen Stellen des aufgesteckten Hohlprofils (17) an, was die Rückhaltewirkung erhöht.The spring bridges (12) can have a laterally acting retaining element (6) in the form of an obliquely outwardly projecting spring nose, at least at one edge region. The spring lugs (6, 8) press against the adjacent inner walls of the hollow profile (17) and engage, for example, at the transition between the roof area and the side wall and on the underlying side wall area of the hollow profile (17). FIG. 8 clarifies this configuration. The spring lugs (6) of the spring bridges (12) can according to FIG. 2 have different altitudes and thereby attack at different points of the plugged hollow profile (17), which increases the retention effect.

Der Steckverbinder (1) kann einen Mittenanschlag (4) haben. Dieser wird z.B. von vier beidseits der Mittellinie (5) angeordneten schräg ausgestellten Federnasen (6) gebildet. Er kann alternativ durch Festanschläge, andere Federnasen oder in beliebig anderer geeigneter Weise hergestellt sein.The connector (1) may have a center stop (4). This is formed, for example, by four slanted spring lugs (6) arranged on both sides of the center line (5). He can alternatively by hard stops, others Spring tabs or be prepared in any other suitable manner.

Abwandlungen der gezeigten und beschriebenen Ausführungsformen sind in verschiedener Weise möglich. Dies betrifft zum einen die Querschnittsform des Steckverbinders (1) und die Form und Anordnung seiner Rückhalteelemente an den Seitenwänden (3) oder an anderer Stelle. Ferner kann die Form und Lage der Durchtrittsöffnung(en) (9) variieren. Gleiches gilt für Zahl, Form und Anordnung der Rückhalteelemente (7), die auch in anderer Weise statt als Federnasen ausgebildet sein können. Insbesondere bei einem Steckverbinder aus Kunststoff können Rippen oder andere Rückhalteelemente (7) eingeset werden.Variations of the embodiments shown and described are possible in various ways. This concerns on the one hand the cross-sectional shape of the connector (1) and the shape and arrangement of its retaining elements on the side walls (3) or elsewhere. Furthermore, the shape and position of the passage opening (s) (9) may vary. The same applies to the number, shape and arrangement of the retaining elements (7), which can also be configured in other ways than spring lugs. In particular, in a plastic connector ribs or other retaining elements (7) can be eingeset.
