Description

Die Erfindung geht aus von einem modularen Halterahmen für Steckverbinder nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention is based on a modular holding frame for connectors according to the preamble of independent claim 1.

Derartige Steckverbindermodule werden als Bestandteil eines Steckverbindermodularsystems benötigt, um einen Steckverbinder, insbesondere einen schweren Rechtecksteckverbinder, flexibel an bestimmte Anforderungen bezüglich der Signal- und Energieübertragung z.B. zwischen zwei elektrischen Geräten, anpassen zu können. Üblicherweise werden dazu Steckverbindermodule in entsprechende Steckverbindermodularrahmen, die mitunter auch als Halterahmen, Gelenkrahmen, Modulrahmen oder Modularrahmen bezeichnet werden, eingesetzt. Die Steckverbindermodularrahmen dienen somit dazu, mehrere zueinander gleichartige und/oder auch unterschiedliche Steckverbindermodule aufzunehmen und diese sicher an einer Fläche und/oder in einem Steckverbindergehäuse o.ä. zu befestigen.Such connector modules are required as part of a modular connector system in order to be able to flexibly adapt a connector, in particular a heavy rectangular connector, to certain requirements with regard to signal and energy transmission, e.g. between two electrical devices. For this purpose, connector modules are usually used in corresponding modular connector frames, which are sometimes also referred to as holding frames, articulated frames, module frames or modular frames. The connector modular frames are therefore used to accommodate several mutually similar and/or different connector modules and to fasten them securely on a surface and/or in a connector housing or the like.

Die Steckverbindermodule besitzen in der Regel jeweils einen im Wesentlichen quaderförmigen Isolierkörper. Diese Isolierköper können beispielsweise als Kontaktträger dienen und Kontakte verschiedenster Art aufnehmen und fixieren. Die Funktion eines dadurch gebildeten Steckverbinders ist also sehr flexibel. Es können z.B. pneumatische Module, optische Module, Module zur Übertragung elektrischer Energie und/oder elektrischer analoger und/oder digitaler Signale im jeweiligen Isolierkörper aufgenommen sein und so im Steckverbindermodularsystem Verwendung finden. Zunehmend übernehmen Steckverbindermodule auch mess- und datentechnische Aufgaben.As a rule, the connector modules each have an essentially cuboid insulating body. These insulators can be used, for example, as contact carriers and can hold and fix contacts of all kinds. The function of a connector formed thereby is very flexible. For example, pneumatic modules, optical modules, modules for transmitting electrical energy and/or electrical analog and/or digital signals can be accommodated in the respective insulating body and thus used in the modular connector system. Connector modules are also increasingly taking on measurement and data-related tasks.

Joints are arranged in the fastening ends of the connector modular frame in such a way that the side parts can be moved when the Align the modular connector frame on a mounting surface at right angles to the mounting surface, as a result of which the connector modules enter into a form-fitting connection with the modular connector frame via the mounting means. In practice, such connector modular frames are usually manufactured in a die-casting process, in particular in a zinc die-casting process.

Die Druckschrift DE 10 2015 114 703 A1 offenbart eine Weiterentwicklung eines solchen als Gelenkrahmen ausgestalteten Steckverbindermodularrahmen. Der darin offenbarte Steckverbindermodularrahmen weist zumindest ein Fixierungsmittel auf, über welches die Rahmenhälften in zwei Positionen, einer offenen Position und einer geschlossenen Position, zueinander fixierbar sind, was die Handhabung erheblich vereinfacht.The pamphlet DE 10 2015 114 703 A1 discloses a further development of such a connector modular frame designed as an articulated frame. The connector modular frame disclosed therein has at least one fixing means, via which the frame halves can be fixed in relation to one another in two positions, an open position and a closed position, which considerably simplifies handling.

Die Druckschrift DE 20 2013 103 611 U1 zeigt zwei äußerst stabil miteinander verschraubbare, in Stanzbiegetechnik preiswert herstellbare und zusammenschraubbare Rahmenhälften, die zur Aufnahme von u.a. pneumatischen Modulen geeignet sind. Der so montierte Steckverbindermodularrahmen weist auch unter hoher mechanischer Langzeitbelastung nur sehr geringe Kriecheigenschaften auf. Nachteilig ist jedoch, dass der Aufwand zum Hinzufügen oder Auswechseln eines Steckverbindermoduls äußerst hoch ist.The pamphlet DE 20 2013 103 611 U1 shows two frame halves that can be screwed together extremely stably, can be manufactured inexpensively using stamping and bending technology and can be screwed together, which are suitable for accommodating pneumatic modules, among other things. The modular connector frame assembled in this way has only very low creep properties, even under high mechanical long-term stress. The disadvantage, however, is that the effort involved in adding or replacing a connector module is extremely high.

Es hat sich in der Praxis jedoch gezeigt, dass solche Steckverbindermodularrahmen bei der Montage eine aufwändige Bedienung erfordern.However, it has been shown in practice that such modular connector frames require complex operation during assembly.

Die Druckschrift EP 1 801 927 B1 offenbart einen einteiligen Steckverbindermodularrahmen, der aus Kunststoffmaterial besteht. Der Steckverbindermodularrahmen ist als umlaufender Kragen ausgebildet und weist an seiner Steckseite mehrere durch Schlitze getrennte Wandsegmente auf. Jeweils zwei gegenüberliegende Wandsegmente bilden einen Einfügebereich für ein Steckverbindermodul, wobei die Wandsegmente fensterartige Öffnungen aufweisen, die zur Aufnahme von an den Schmalseiten der Module angeformten Vorsprüngen dienen. Weiterhin ist in den Wandsegmenten jeweils eine Führungsnut vorgesehen. Die Führungsnut ist oberhalb der Öffnungen mittels eines nach außen versetzten Fenstersteges gebildet, der auf der Innenseite eine Einführungsschräge aufweist. Zusätzlich weisen die Steckverbindermodule Rastarme auf, die an den Schmalseiten in Richtung der Kabelanschlüsse wirkend, angeformt sind, und unterhalb der seitlichen Kragenwand verrasten, so dass zwei unabhängige Rastmittel die Steckverbindermodule im Steckverbindermodularrahmen fixieren.The pamphlet EP 1 801 927 B1 discloses a one-piece connector modular frame made of plastic material. The connector modular frame is designed as a peripheral collar and has several wall segments separated by slots on its plug-in side. Two opposite wall segments each form an insertion area for a connector module, the wall segments having window-like openings which serve to accommodate projections formed on the narrow sides of the modules. Furthermore, a guide groove is provided in each of the wall segments. The guide groove is formed above the openings by means of a window web which is offset outwards and has an insertion bevel on the inside. In addition, the connector modules have latching arms which are formed on the narrow sides and act in the direction of the cable connections and latch below the lateral collar wall, so that two independent latching means fix the connector modules in the modular connector frame.

Die Druckschrift DE 10 2013 113 976 B4 offenbart einen Steckverbindermodularrahmen für einen schweren Steckverbinder zur Aufnahme gleichartiger und/oder unterschiedlicher Steckverbindermodule. Der Steckverbindermodularrahmen besteht aus einem im Querschnitt rechteckigen Grundrahmen, der zwei sich gegenüberliegenden Seitenteile aufweist. An den Seitenteilen ist jeweils ein Wangenteil, bestehend aus einem flexiblen Material, insbesondere federelastischem Blech, angebracht. Beim Einführen eines Steckverbindermoduls in den Steckverbindermodularrahmen senkrecht zur Rahmenebene werden diese Wangenteile zunächst vom Seitenteil weg nach außen gebogen. Insbesondere können die Wangenteile Laschen mit Rastfenstern, besitzen, welche dazu geeignet sind, die Steckverbindermodule an deren Rastnasen einzeln im Steckverbindermodularrahmen zu verrasten. Die Steckverbindermodule können somit einzeln und mit nur geringem Aufwand aus der Kabelanschlussrichtung und in Steckrichtung in den Steckverbindermodularrahmen eingeschoben und in umgekehrter Richtung wieder entnommen werden. Das eingesteckte Steckverbindermodul ist vom Grundrahmen des Steckverbindermodularrahmen in der Rahmenebene fest und stabil gehalten. In ihrer Einführrichtung, senkrecht zur Rahmenebene, können sie mit ihren Rastnasen jeweils zwischen zwei einander gegenüberliegenden Laschen verrasten. Diese Bauform hat grundsätzlich den Vorteil, dass die Steckverbindermodule einzeln eingesteckt und entnommen werden können, ohne dass die Befestigung der anderen Module davon beeinträchtigt wird. Die Bauform gestattet es weiterhin, dass der Steckverbindermodularrahmen aus Metall besteht und ermöglicht somit die besagte Schutzerdung.The pamphlet DE 10 2013 113 976 B4 discloses a connector modular frame for a heavy connector for accommodating like and/or different connector modules. The connector modular frame consists of a base frame with a rectangular cross section, which has two opposite side parts. A cheek piece consisting of a flexible material, in particular spring-elastic sheet metal, is attached to each of the side pieces. When inserting a connector module into the connector modular frame perpendicular to the plane of the frame, these cheek parts are first bent outward away from the side part. In particular, the cheek parts can have tabs with latching windows, which are suitable for latching the connector modules individually at their latching lugs in the modular connector frame. The connector modules can thus be pushed individually and with little effort from the cable connection direction and in the plugging direction into the connector modular frame and removed again in the opposite direction. The plugged connector module is from the base frame of the Connector modular frame held firmly and stably in the frame plane. In their direction of insertion, perpendicular to the plane of the frame, they can each engage with their latching lugs between two opposite tabs. This design has the fundamental advantage that the connector modules can be plugged in and removed individually without affecting the attachment of the other modules. The design also allows the connector modular frame to be made of metal, thus enabling said protective grounding.

Weiterhin besitzen die Module in solchen bekannten Steckverbindermodularrahmen grundsätzlich ein gewisses "Spiel", d.h. sie sind mit einer bestimmten mechanischen Toleranz im Steckverbindermodularrahmen gehalten. Dies ist in technischer Hinsicht, zumindest in einem bestimmten Maße, für die meisten Anwendungen auch als notwendig anzusehen, da es dazu dient, beim Steckvorgang entsprechende Toleranzen gegenüber dem Gegensteckverbinder auszugleichen. Wird diese Toleranz allerdings zu groß, wie es beim letztgenannten Stand der Technik zuweilen zu beobachten ist, so kann dies dazu führen, dass die Fixierung der Steckverbindermodule über die oben erwähnten Wangenteile den Anforderungen einiger industrieller Bereiche nicht genügt. Aus einem zu großen Spiel innerhalb des Grundkörpers des Steckverbindermodularrahmens können nämlich oft auch zu hohe Steck- und Ziehkräfte beim Zusammenfügen bzw. Trennen von Steckverbinder und Gegensteckverbinder resultieren. Die Kontaktelemente können dadurch weiterhin auch, beispielsweise beim Steckvorgang, verkanten, wodurch zudem auch ein höherer Abrieb entsteht und nach einiger Zeit möglicherweise sogar die Gefahr eines Überspannungsbogens besteht. Auch aus datentechnischer Sicht kann sich das besagte Spiel bei Verwendung bestimmter datentechnischer Steckverbindermodule von Nachteil sein, da diese Toleranz gegebenenfalls eine elektronische Busanbindung erheblich erschwert. Alle oben erwähnten Halterahmen sind dafür ausgelegt mehrfach und zum Teil mit unterschiedlichen Steckverbindermodulen bestückt zu werden. Daher muss der Halterahmen eine gewisse mechanische Stabilität und in seinen Verriegelungsmitteln für die Steckverbindermodule eine gewisse Haltbarkeit aufweisen.Furthermore, the modules in such known connector modular frames basically have a certain "play", ie they are held with a specific mechanical tolerance in the connector modular frame. From a technical point of view, this is also to be considered necessary, at least to a certain extent, for most applications, since it serves to compensate for corresponding tolerances in relation to the mating connector during the plugging process. However, if this tolerance becomes too large, as can sometimes be observed in the last-mentioned prior art, this can result in the fixing of the connector modules via the above-mentioned cheek parts not meeting the requirements of some industrial sectors. Excessive play within the base body of the modular connector frame can often result in excessive insertion and removal forces when the connector and mating connector are joined or separated. As a result, the contact elements can also tilt, for example during the plugging process, which also results in greater abrasion and, after some time, there may even be the risk of an overvoltage arc. From a data technology point of view, said play can also be disadvantageous when using certain data technology connector modules, since this tolerance may make an electronic bus connection considerably more difficult. All of the holding frames mentioned above are designed to be fitted multiple times and in some cases with different connector modules. The holding frame must therefore have a certain mechanical stability and its locking means for the connector modules must have a certain durability.

Soll ein Halterahmen nur selten oder gar nur einmal mit Steckverbindermodulen bestückt werden, sind die Halterahmen aus dem Stand der Technik einerseits zu aufwendig zu bedienen und andererseits technisch überqualifiziert und zu teuer.If a holding frame is to be fitted with connector modules only rarely or only once, the holding frames from the prior art are too complicated to operate on the one hand and technically overqualified and too expensive on the other hand.

Aufgabenstellungtask

Die Aufgabe der Erfindung besteht darin, einen Halterahmen für Steckverbinder, genauer Steckverbindermodule, oder mit anderen Worten einen Steckverbindermodularrahmen, vorzuschlagen, welche flexibel einsetzbar und einfach handhabbar ist. Ferner soll er stabil und kostengünstig herstellbar sein.The object of the invention is to propose a holding frame for connectors, more precisely connector modules, or in other words a connector modular frame, which can be used flexibly and is easy to handle. Furthermore, it should be stable and inexpensive to produce.

Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The object is solved by the characterizing features of independent claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous refinements of the invention are specified in the dependent claims.

Der erfindungsgemäße Halterahmen ist zum Einsatz in schweren Steckverbinder, welche auch unter dem Begriff "Industriesteckverbinder" bekannt sind, vorgesehen. In den Halterahmen können gleichartige und/oder unterschiedliche Steckverbindermodule reversibel eingesetzt werden. Dadurch kann ein Steckverbinder je nach Einsatzgebiet und Kundenwunsch variabel zusammengestellt werden. Erfindungsgemäß besteht der Halterahmen im Wesentlichen aus mindestens einem, insbesondere zwei, bevorzugter Weise vier, Halterahmenmodulen. Dies bedeutet, dass der Halterahmen aus einem oder mehreren Elementen, also Halterahmenmodulen, zusammensetzbar ist.The holding frame according to the invention is intended for use in heavy-duty connectors, which are also known by the term “industrial connectors”. Similar and/or different connector modules can be reversibly inserted into the holding frame. This means that a connector can be put together variably depending on the area of application and customer requirements. According to the invention, the holding frame consists essentially of at least one in particular two, preferably four, holding frame modules. This means that the holding frame can be assembled from one or more elements, ie holding frame modules.

Erfindungsgemäß besteht das Halterahmenmodul aus mindestens zwei gestanzten oder gelaserten, puzzelartigen Wandelementen.According to the invention, the holding frame module consists of at least two punched or lasered, puzzle-like wall elements.

Durch das Stanz- oder Laserverfahren in der Herstellung der Wandelemente ergeben sich präzise Schneidkanten sowie saubere Konturen. Diese bieten den Vorteil, dass sie sich besser miteinander kombinieren und/oder verbinden lassen, da die Toleranzen geringer ausfallen als bei anderen Herstellungsverfahren. Zudem ist der Herstellungsprozess durch die beiden Verfahren optimal automatisierbar und folglich auch schneller, effizienter und ressourcenschonender.The stamping or laser process used to manufacture the wall elements results in precise cutting edges and clean contours. These offer the advantage that they can be better combined and/or connected to one another, since the tolerances are lower than with other manufacturing processes. In addition, the manufacturing process can be optimally automated using the two methods and is therefore also faster, more efficient and more resource-saving.

Erfindungsgemäß ist das Halterahmenmodul aus mindestens zwei puzzleteilartigen Wandelementen gebildet. Durch die Puzzleteilform sind die mindestens zwei Wandelement stabil miteinander verbindbar. Zudem sind sie so beliebig erweiterbar in Abhängigkeit der gewünschten Anzahl an Steckverbindermodulen. Dieses Merkmal bietet den Vorteil, dass nur eine sehr geringe Anzahl an Varianten von Wandelementen auf Lager gehalten werden muss. Dies reduziert Kosten, erhöht die flexible Einsetzbarkeit und schont Ressourcen.According to the invention, the holding frame module is formed from at least two wall elements that resemble puzzle pieces. The at least two wall elements can be connected to one another in a stable manner due to the shape of the puzzle pieces. In addition, they can be expanded as required, depending on the desired number of connector modules. This feature offers the advantage that only a very small number of variants of wall elements have to be kept in stock. This reduces costs, increases flexibility and saves resources.

In einer vorteilhaften Ausgestaltung bestehen die mindestens zwei puzzleteilartigen Wandelemente aus Kunststoff oder Metall. BeideIn an advantageous embodiment, there are at least two Puzzle piece-like wall elements made of plastic or metal. Both

Materialen sind für das Stanz- oder Laserverfahren geeignet und geben dem Halterahmen genügend Stabilität.Materials are suitable for the stamping or laser process and give the holding frame sufficient stability.

Vorteilhafter Weise weisen die mindestens zwei puzzleteilartigen Wandelemente jeweils mindestens eine Anformung und mindestens eine Ausnehmung auf. Idealerweise liegen mindestens eine Ausnehmung und mindestens eine Anformung einander gegenüber wie bei einem Puzzleteil aus einem Kinderpuzzle. Bevorzugter Weise ist die mindestens eine Anformung umbiegbar, sodass sie eine feste Verbindung mit einem rechtwinklig angeordneten Element, beispielsweise einer PE-Wand, verbunden und fixiert werden kann. Durch das Umbiegen wird der Halt gegen die wirkenden Steckkräfte erhöht, da eine feste Verbindung zwischen Wandelement, bzw. Halterahmenmodul, und rechtwinklig angeordnetem Element vorliegt.Advantageously, the at least two puzzle piece-like wall elements each have at least one projection and at least one recess. Ideally, at least one recess and at least one projection are opposite one another, like a puzzle piece from a children's puzzle. Preferably, the at least one projection can be bent, so that it can be connected and fixed with a fixed connection to an element arranged at right angles, for example a PE wall. By bending over, the hold against the acting insertion forces is increased, since there is a firm connection between the wall element or holding frame module and the element arranged at right angles.

In einer vorteilhaften Ausgestaltung weist der Halterahmen ein Fixiermittel auf und ist dadurch stabilisierbar. Das Fixiermittel dient der Sicherung und Stabilisierung der aufgenommenen Steckverbindermodule, sowie der Halterahmenmodule und eventueller Wandelemente.In an advantageous embodiment, the holding frame has a fixing means and can be stabilized as a result. The fixing means is used to secure and stabilize the plug connector modules, as well as the holding frame modules and any wall elements.

Bevorzugter Weise ist das Fixiermittel ein Kabelbinder oder ein Zusatzrahmen oder ein Gurt. Das Fixiermittel ist so ausgestaltet, dass es einen bestückten Halterahmen umfassen kann. Es verläuft dabei entlang der Halterahmenmodule beziehungsweise der Wandelemente, also senkrecht zur Steckrichtung des Halterahmens. Die Verwendung von Kabelbinder oder Gurt hat den Vorteil, dass sie individuell an den Umfang des Halterahmens anpassbar sind, was zu niedrigen Lagerkosten auf Grund der geringen Variantenvielfalt führt.The fixing means is preferably a cable tie or an additional frame or a belt. The fixing means is designed in such a way that it can include an equipped holding frame. It runs along the holding frame modules or the wall elements, ie perpendicular to the direction of insertion of the holding frame. The usage of Cable ties or straps have the advantage that they can be individually adapted to the circumference of the holding frame, which leads to low storage costs due to the small number of variants.

Idealerweise besteht der Zusatzrahmen aus Metall oder Kunststoff.Ideally, the additional frame is made of metal or plastic.

Dadurch ist er kostengünstig herstellbar. Der Zusatzrahmen bietet gegenüber dem Kabelbinder oder dem Gurt den Vorteil, dass er ebenso stabil ist und zusätzlich für einen Anwender einfach zu montieren ist, da er nur über den Halterahmen geschoben werden muss.As a result, it can be produced inexpensively. Compared to the cable tie or the belt, the additional frame offers the advantage that it is just as stable and is also easy for a user to assemble, since it only has to be pushed over the holding frame.

Erfindungsgemäß weist der Halterahmen mindestens eine PE-Wand mit einem Anschluss zur Schutzerdung und mindestens ein Mittel zur Befestigung auf. Die PE-Wand dient dem Anschluss der Schutzerdung und ist erforderlich. Die PE-Wand ist idealerweise rechtwinklig zu dem mindestens einen Halterahmenmodul angeordnet. Von einem viereckigen, bevorzugter Weise rechteckigen oder quadratischen, Halterahmen ausgehend bildet die PE-Wand jeweils zwei gegenüberliegende, parallele Seiten. Die beiden verbleibenden, parallelen Seiten werden jeweils durch mindestens ein Halterahmenmodul gebildet. Zudem weist der Halterahmen noch mindestens ein Mittel zur Befestigung auf, welches zur Montage des Halterahmens in einem Steckverbindergehäuse dient. .According to the invention, the holding frame has at least one PE wall with a connection for protective earthing and at least one attachment means. The PE wall is used to connect the protective earth and is required. The PE wall is ideally arranged at right angles to the at least one holding frame module. Starting from a four-cornered, preferably rectangular or square, holding frame, the PE wall forms two opposite, parallel sides. The two remaining, parallel sides are each formed by at least one holding frame module. In addition, the holding frame also has at least one attachment means, which is used to mount the holding frame in a connector housing. .

In einer bevorzugten Ausgestaltung besteht die PE-Wand aus einem Metall. Dadurch kann beim Anschluss einer Schutzerdung an die PE-Wand eine solche ohne weitere Hilfsmittel erzielt werden. Es ist auch eine Ausgestaltung der PE-Wand aus Kunststoff denkbar, jedoch ist diese nur in Verbindung mit darauf fixierten Metallelementen als Anschluss der Schutzerdung geeignet.In a preferred embodiment, the PE wall consists of a metal. When connecting a protective earth to the PE wall, this can be achieved without any additional tools. A design of the PE wall made of plastic is also conceivable, but this is only suitable as a protective earth connection in conjunction with metal elements fixed thereon.

Vorteilhafter Weise ist die PE-Wand im Stanz-Biegeverfahren oder Gussverfahren herstellbar. Dies vereinfacht den Produktionsprozess, was folglich Kosten spart.Advantageously, the PE wall can be produced using a stamping and bending process or a casting process. This simplifies the production process, which consequently saves costs.

Idealerweise ist der Anschluss zur Schutzerdung ein PE-Kontakt. Dadurch ist ein Schutzleiter für einen Anwender einfach anschließbar und die erforderliche Schutzerdung sicher gewährleistet.Ideally, the connection to protective earth is a PE contact. As a result, a protective conductor can be easily connected by a user and the necessary protective earthing is reliably guaranteed.

Eine vorteilhafte Ausgestaltung sieht vor, dass das Mittel zur Befestigung Schrauben, Nieten, Bolzen, Stifte oder ähnliches sind, wobei das Mittel zur Befestigung zur Montage des Halterahmens in einem Steckverbindergehäuse dient. Unter dem Begriff "ähnlichem" sind alle hier nicht genannten Befestigungsmittel gemeint, welche Funktionen analog der genannten Befestigungsmittel erfüllen und den Halterahmen entsprechend fixieren können.An advantageous embodiment provides that the means for fastening are screws, rivets, bolts, pins or the like, the means for fastening being used for mounting the holding frame in a connector housing. The term "similar" means all fastening means not mentioned here, which fulfill functions analogous to the fastening means mentioned and can fix the holding frame accordingly.

Die Figuren enthalten teilweise vereinfachte, schematische Darstellungen. Zum Teil werden für gleiche, aber gegebenenfalls nicht identische Elemente identische Bezugszeichen verwendet. Verschiedene Ansichten gleicher Elemente könnten unterschiedlich skaliert sein.The figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for the same but possibly not identical elements. Different views of the same elements could be scaled differently.

Die Figuren 1 und 2 zeigen jeweils eine perspektivische Darstellung eines nicht erfindungsgemäßen Halterahmens mit zwei Halterahmenmodulen 2 und drei aufgenommenen Steckverbindermodulen 1.The Figures 1 and 2 each show a perspective view of a holding frame not according to the invention with two holding frame modules 2 and three plug connector modules 1.

Die Anzahl der Steckverbindermodule 1 ist in den fünf Figuren jeweils nur exemplarisch. Der Übersichtlichkeit halber ist jeweils nur ein Bestandteil des Halterahmens mit einem Bezugszeichen versehen auch wenn mehrere Bestandteile gleicher Art verbaut sind.The number of connector modules 1 in each of the five figures is only an example. For the sake of clarity, only one component of the holding frame is provided with a reference number, even if several components of the same type are installed.

Der Unterschied zwischen den beiden Figuren liegt in der PE-Wand 7. Je Halterahmen sind zwei PE-Wände 7 verbaut. In der Figur 1 ist jedoch nur eine PE-Wand 7 fertig montiert, die zweite PE-Wand 7 jedoch noch nicht. Folglich zeigt die Figur 1 einen unfertigen Halterahmen, die Figur 2 einen fertig bestückten.The difference between the two figures lies in the PE wall 7. Two PE walls 7 are installed for each holding frame. In the figure 1 However, only one PE wall 7 is fully assembled, but the second PE wall 7 is not yet. Consequently, the figure 1 an unfinished holding frame, the figure 2 a fully equipped one.

Der Halterahmen besteht in beiden Figuren aus zwei parallelen, einander gegenüberliegenden Halterahmenmodulen 2. Bei den Halterahmenmodulen handelt es sich um gestanzte oder gelaserte Metallelemente, welche jeweils Ausnehmung für Rastnasen von Steckverbindermodulen 1 aufweisen. Die Ausnehmung ist jeweils entsprechend der Kontur der Rastnase des Steckverbindermoduls 1 ausgeformt.In both figures, the holding frame consists of two parallel holding frame modules 2 lying opposite one another. The recess is shaped in accordance with the contour of the latching lug of the connector module 1.

Das Halterahmenmodul 2 weist auf zwei Seiten jeweils mindestens eine Lasche 2.1, hier jeweils zwei Laschen 2.1, auf. Dabei sind die Laschen 2.1 so angeordnet, dass sie mit der jeweiligen PE-Wand 7 zusammenwirken und verrasten können. Für die Verrastung weist die PE-Wand 7 entsprechende Ausnehmungen auf, wie in der Figur 2 zu sehen ist. Während in der Figur 1 nur eine PE-Wand 7 schon mit den zwei Halterahmenmodulen 2 verrastet ist, sind es in der Figur 2 beide PE-Wände 7. Durch diese Verrastung mit den Halterahmenmodulen 2 und den eingesetzten Steckverbindermodulen 1 erhält der Halterahmen seine optimale Stabilität.The holding frame module 2 has on each of two sides at least one tab 2.1, in this case two tabs 2.1. The tabs 2.1 are arranged in such a way that they can interact and latch with the respective PE wall 7. For the latching, the PE wall has 7 corresponding recesses, as in the figure 2 you can see. while in the figure 1 only a PE wall 7 is already locked with the two holding frame modules 2, there are in the figure 2 both PE walls 7. This latching with the holding frame modules 2 and the inserted connector modules 1 gives the holding frame its optimal stability.

Die PE-Wand 7 besteht in allen Figuren, also Figur 1 bis Figur 5, aus einer Wand, welche bevorzugter Weise aus Metall oder aus Kunststoff mit einer metallischen Anformung zur Sicherstellung der Leitfähigkeit gebildet ist. Zudem weist die PE-Wand einen Anschluss zur Schutzerdung 8 auf und mindestens ein, hier zwei, Mittel zur Befestigung 9 auf.The PE wall 7 exists in all figures, ie Figure 1 to Figure 5 , From a wall, which is preferably formed of metal or plastic with a metallic molding to ensure conductivity. In addition, the PE wall has a connection to the protective grounding 8 and at least one, in this case two, attachment means 9 .

Bei dem Anschluss zur Schutzerdung 8 handelt es sich um einen PE-Kontakt, wie er im Stand der Technik hinreichend bekannt und vorgeschrieben ist.The connection to protective grounding 8 is a PE contact, as is well known and prescribed in the prior art.

Bei dem Mittel zur Befestigung 9 handelt es sich in allen Figuren um eine Schraube, genauer je PE-Wand 7 um zwei Schrauben. Mittels der Schrauben ist der Halterahmen in ein Steckverbindergehäuse einmontierbar ohne das spezielles Werkzeug für einen Anwender notwendig ist.The means for fastening 9 is a screw in all figures, more precisely two screws for each PE wall 7 . The holding frame can be installed in a connector housing by means of the screws without the need for a special tool for the user.

Die Figur 3 zeigt eine weitere Ausführungsform eines nicht erfindungsgemäßen Halterahmens. In dieser Figur weist der Halterahmen neben den beiden PE-Wänden 7 und den drei aufgenommen Steckverbindermodulen 1 zwei Schienen 4 auf. In dieser Variante ersetzen die beiden Schienen 4 die beiden Halterahmenmodule 2 aus den Figuren 1 und 2.The figure 3 shows a further embodiment of a holding frame not according to the invention. In this figure, the holding frame has two rails 4 in addition to the two PE walls 7 and the three connector modules 1 accommodated. In this variant, the two rails 4 replace the two holding frame modules 2 from the Figures 1 and 2 .

Bei den Schienen 4 handelt es sich jeweils um eine u-förmige Schiene. Sie weist jeweils zwei parallele, lange Schenkel auf, welche mittels eines im Verhältnis kürzeren Verbindungsstücks verbunden sind. Das Verbindungsstück sorgt für die notwendige Beabstandung der beiden Schenkel. Die Beabstandung ist dabei so ausgestaltet, dass die Rastnasen der Steckverbindermodule 1 zwischen den beiden Schenkeln der Schiene 4 aufgenommen und sicher gehalten werden können. Die Schienen 4 sind ihrer Länge der Schenkel in Überlänge ausgestaltet und können je nach Bedarf, sprich je nach Anzahl der aufgenommen Steckverbindermodule, hier drei, gekürzt werden. Die offenen Enden der beiden Schienen 4 werden in der Figur 3 mittels einer Federspange 5 fixiert und arretiert.The rails 4 are each a U-shaped rail. It has two parallel, long legs, which by means of a connected with a relatively shorter connector. The connecting piece provides the necessary spacing between the two legs. The spacing is designed in such a way that the latching lugs of the connector modules 1 can be accommodated between the two legs of the rail 4 and held securely. The rails 4 are designed to be longer than their legs and can be shortened as required, ie depending on the number of plug-in connector modules, three in this case. The open ends of the two rails 4 are in the figure 3 fixed and locked by means of a spring clip 5.

Bei der Federspange 5 handelt es sich um einen u-förmigen Gegenstand mit elastische Eigenschaften, welcher in seiner Formgebung einer Schiene 4 entspricht, sprich ebenfalls zwei parallele Schenkel und ein dazugehöriges Verbindungstück aufweist. Die Federspange 5 ist auf das offene Ende der jeweiligen Schiene 4 aufgeschoben und sichert so die aufgenommenen Steckverbindermodule 1 gegen Herausfallen. Dabei liegt beim Stecken auf die Schiene 4 das Verbindungsstück der Federspange auf einem der beiden Schenkel der Schiene 4 an und die beiden Schenkel der Federspange 5 sind senkrecht zu den Schenkeln der Schiene angeordnet.The spring clip 5 is a U-shaped object with elastic properties, the shape of which corresponds to a rail 4, i.e. it also has two parallel legs and an associated connecting piece. The spring clip 5 is slid onto the open end of the respective rail 4 and thus secures the plug connector modules 1 that have been accommodated against falling out. When it is plugged onto the rail 4, the connecting piece of the spring clip rests on one of the two legs of the rail 4 and the two legs of the spring clip 5 are arranged perpendicularly to the legs of the rail.

In der Figur 3 handelt es sich um eine besondere Ausgestaltung der Federspange 5, nämlich um eine Erweiterung der beschriebenen Federspange 5. Die Federspange 5 ist hier so ausgestaltet ist, dass sie auf beide verwendete Schienen 4 gleichzeitig einwirken kann. Die Erweiterung ist wie ein U geformt. An den beiden Schenkeln der Erweiterung ist jeweils eine Federspange 5, wie oben beschrieben, angeordnet. Dadurch können beide Schienen 4 zeitgleich fixiert und arretiert werden.In the figure 3 It is a special embodiment of the spring clip 5, namely an extension of the spring clip 5 described. The spring clip 5 is designed here in such a way that it can act on both rails 4 used at the same time. The extension is shaped like a U. A spring clip 5, as described above, is arranged on each of the two legs of the extension. As a result, both rails 4 can be fixed and locked at the same time.

Die Figur 4 zeigt eine Ausführungsform eines erfindungsgemäßen Halterahmens. Hier ist der Unterschied zu den vorherigen Figuren, dass die Halterahmenmodule 2 mehrteilig sind. Jedes Halterahmenmodul 2 besteht aus einzelnen Wandelementen 3. In der Figur 4 sind es jeweils drei Wandelemente 3 je Halterahmenmodul 2. Hier dienen die Wandelemente 3 als Verbindung zwischen den beiden PE-Wänden 7. Jedes Wandelement 3 ist puzzleteilartig ausgestaltet. Das heißt, es weist mindestens eine Anformung 3.1 und mindestens eine Ausnehmung 3.2 auf. Im vorliegenden Ausführungsbeispiel weist jedes Wandelement 3 drei Anformungen 3.1 und drei Ausnehmungen 3.2 auf. Dabei erinnern zwei Anformungen 3.1 bzw. zwei Ausnehmungen 3.2 an die Formen eines Puzzleteils, während eine Anformung 3.1 bzw. eine Ausnehmung 3.2 rechteckig ausgestaltet und zwischen den beiden Anformungen 3.1 bzw. Ausnehmungen 3.2 angeordnet ist. Die Anformungen 3.1 und die Ausnehmungen 3.2 sind so ausgestaltet, dass sie eine einfach erzeugbare Verbindung ohne Hilfsmittel zwischen zwei Wandelementen 3 gewährleisten.The figure 4 shows an embodiment of a holding frame according to the invention. The difference here from the previous figures is that the holding frame modules 2 are in several parts. Each holding frame module 2 consists of individual wall elements 3. In the figure 4 there are three wall elements 3 per holding frame module 2. Here the wall elements 3 serve as a connection between the two PE walls 7. Each wall element 3 is designed like a puzzle piece. That is, it has at least one projection 3.1 and at least one recess 3.2. In the present exemplary embodiment, each wall element 3 has three projections 3.1 and three recesses 3.2. Two projections 3.1 or two recesses 3.2 are reminiscent of the shapes of a puzzle piece, while one projection 3.1 or one recess 3.2 is rectangular and is arranged between the two projections 3.1 or recesses 3.2. The projections 3.1 and the recesses 3.2 are designed in such a way that they ensure a connection between two wall elements 3 that can be produced easily and without tools.

Um die Stabilität des gesamten Halterahmens noch zu erhöhen, weisen die PE-Wände 7 in diesem Ausführungsbeispiel ebenfalls entsprechende Anformungen bzw. Ausnehmungen auf, welche mit den Anformungen 3.1 und den Ausnehmungen 3.2 der Wandelemente 3 verrastet sind. Alternativ könnten die Anformungen 3.1 auch biegsam ausgestaltet sein, analog der Laschen 2.1 aus den Figuren 1 und 2.In order to further increase the stability of the entire holding frame, the PE walls 7 in this exemplary embodiment also have corresponding projections or recesses, which are latched to the projections 3.1 and the recesses 3.2 of the wall elements 3. Alternatively, the projections 3.1 could also be designed to be flexible, analogous to the tabs 2.1 from FIGS Figures 1 and 2 .

Die Figur 5 zeigt eine weitere Ausgestaltung der Figur 4. Auch hier besteht das Halterahmenmodul 2 aus drei Wandelementen 3. Dieses sind ebenfalls mittels Anformungen 3.1 und Ausnehmungen 3.2 miteinander verrastet. Jedoch sind die Anformungen 3.1 und die Ausnehmungen 3.2 als geometrische Figuren ausgestaltet anstatt als Rechteck und als Puzzleteil.The figure 5 shows another embodiment of the figure 4 . Here, too, the holding frame module 2 consists of three wall elements 3. These are also locked together by means of projections 3.1 and recesses 3.2. However, the projections 3.1 and the recesses 3.2 are designed as geometric figures instead of as a rectangle and as a puzzle piece.

Zusätzlich zur Erhöhung der Stabilität weist der Halterahmen ein Fixiermittel 6 auf. Hierbei handelt es sich um einen Kabelbinder, welcher umlaufend um den fertig bestückten Halterahmen gelegt und festgespannt wurde. Durch das Fixiermittel sind die PE-Wände 7, die Wandelemente 3 und die Steckverbindermodule 1 fest und sicher miteinander verbunden.In addition to increasing the stability, the holding frame has a fixing means 6 . This is a cable tie, which is placed and tightened all the way around the fully equipped holding frame. The PE walls 7, the wall elements 3 and the connector modules 1 are firmly and securely connected to one another by the fixing means.

Das Fixiermittel 6 kann nicht nur mit der Halterahmenvariante gemäß Figur 4 verwendet werden, sondern eignet sich auch für den Einsatz in Kombination mit den anderen Halterahmenvarianten gemäß der Figuren 1 bis 3.The fixing means 6 can not only be in accordance with the holding frame variant figure 4 are used, but is also suitable for use in combination with the other holding frame variants according to Figures 1 to 3 .

Auch wenn in den Figuren verschiedene Aspekte oder Merkmale der Erfindung jeweils in Kombination gezeigt sind, ist für den Fachmann - soweit nicht anders angegeben - ersichtlich, dass die dargestellten und diskutierten Kombinationen nicht die einzig möglichen sind. Insbesondere können einander entsprechende Einheiten oder Merkmalskomplexe aus unterschiedlichen Ausführungsbeispielen miteinander ausgetauscht werden.Even if different aspects or features of the invention are shown in combination in the figures, it is obvious to the person skilled in the art--unless stated otherwise--that the combinations shown and discussed are not the only possible ones. In particular, mutually corresponding units or complexes of features from different exemplary embodiments can be exchanged with one another.
