Abstract

When compressed air is transmitted, and in particular owing to the high contact pressure against a corresponding mating plug required for this purpose, plug connector retaining frames which are fitted with pneumatic modules (2, 3) are often also exposed to high forces over a long period of time. Owing to their associated slowly progressing deformation ("creepage"), air can escape from between the modules (2, 3), as a result of which the quality of the pneumatic signal transmission is considerably impaired. In order to improve this quality, the holding frame according to the invention comprises two holding frame parts which are produced from sheet metal. Each of these two sheet metal parts (1, 1') can have at least two contact regions (14, 14') with associated contact areas at which the sheet metal parts (1, 1') are screwed to one another by screws (142). A holding frame according to the invention, which is intended to receive six modules (2, 3), can therefore be fully fitted with pneumatic modules (2, 3) and despite this ensure high-quality pneumatic signal transmission.

Description

Halterahmen für Steckverbinder  Holding frame for connectors
Beschreibung description
Die Erfindung betrifft einen Halterahmen nach dem Oberbegriff des unabhängigen Hauptanspruchs 1 . The invention relates to a holding frame according to the preamble of independent main claim 1.
Derartige Halterahmen werden benötigt, um mehrere zueinander gleichartige und/oder auch unterschiedliche Module aufzunehmen. Bei diesen Modulen kann es sich beispielsweise um Isolierkörper handeln, die als Kontaktträger für elektronische und elektrische oder auch optische Kontakte vorgesehen sind. Es kann sich aber insbesondere auch um pneumatische Module zur Aufnahme von pneumatischen Stift- oder Buchsenkontakten zur Übertragung pneumatischer Signale handeln. Such support frames are required to accommodate a plurality of similar and / or different modules. These modules may be, for example, insulating body, which are provided as a contact carrier for electronic and electrical or optical contacts. But it can also be in particular pneumatic modules for receiving pneumatic pin or socket contacts for the transmission of pneumatic signals.
Stand der Technik State of the art
Aus der Druckschrift EP0860906B1 ist ein Halterahmen zur Halterung von Steckverbindermodulen und zum Einbau in Steckverbindergehäuse bzw. zum Anschrauben an Wandflächen bekannt, wobei die Steckverbindermodule in den Halterahmen eingesetzt sind und Halterungsmittel an den Steckverbindermodulen mit an gegenüberliegenden Wandteilen (Seitenteilen) des Halterahmens vorgesehenen Ausnehmungen zusammenwirken, wobei die Ausnehmungen als allseitig geschlossene Öffnungen in den Seitenteilen des Halterahmens ausgebildet sind, wobei der Halterahmen aus zwei gelenkig miteinander verbundenen Hälften besteht, wobei die Trennung des Halterahmens quer zu den Seitenteilen des Rahmens vorgesehen ist, und wobei Gelenke in den Befestigungsenden des Halterahmens derart angeordnet sind, dass beim Aufschrauben des Halterahmens auf eine Befestigungsfläche sich die Rahmenteile derart ausrichten, dass die Seitenteile des Halterahmens rechtwinklig zur Befestigungsfläche ausgerichtet sind und die Steckverbindermodule über die Halterungsmittel eine formschlüssige Verbindung mit dem Halterahmen aufweisen. From EP0860906B1 a holding frame for mounting connector modules and for installation in connector housing or for screwing to wall surfaces is known, wherein the connector modules are inserted into the support frame and support means cooperate with the connector modules with provided on opposite wall parts (side parts) of the support frame recesses, wherein the recesses are formed as all-round closed openings in the side parts of the holding frame, wherein the holding frame consists of two hinged halves, wherein the separation of the holding frame is provided transversely to the side parts of the frame, and wherein joints arranged in the attachment ends of the holding frame such are that when screwing the support frame to a mounting surface, the Align frame parts such that the side parts of the support frame are aligned at right angles to the mounting surface and the connector modules have a positive connection with the support frame via the support means.
Die Druckschrift EP1353412B1 offenbart einen modularen Steckverbinder, der aneinanderreihbare und auswechselbare Module aufweist, die in einem aus zwei Hälften bestehenden Halterahmen gehalten sind, wobei die Module zum Anschluss und der Weiterleitung elektrischer, optischer und/oder pneumatischer Signale ausgebildet sind, wobei mindestens ein Modul als Gehäuse ausgebildet ist, das eine Steck- und eine Anschlussseite für elektrische, optische und/oder pneumatische Anschlüsse aufweist, und wobei in dem Gehäuse elektronische, elektrische, optische und/oder pneumatische Schaltmittel vorgesehen sind, mittels derer eingehende Signale veränderbar sind. The document EP1353412B1 discloses a modular connector which has stackable and interchangeable modules which are held in a holding frame consisting of two halves, wherein the modules are designed for connection and forwarding electrical, optical and / or pneumatic signals, wherein at least one module as Housing is formed, which has a plug and a connection side for electrical, optical and / or pneumatic connections, and wherein in the housing electronic, electrical, optical and / or pneumatic switching means are provided by means of which incoming signals are variable.
Nachteilig bei diesem Stand der Technik ist, dass ein solcher Halterahmen, wenn er gleichzeitig mit mehreren pneumatischen Modulen bestückt ist und im Betrieb in dementsprechend hohem Maße zur Luftdruckübertragung genutzt wird, entsprechend hohen Kräften ausgesetzt ist. Dabei sind die pneumatischen Module mit pneumatischen Kontakten, z.B. Stift- und/oder Buchsenkontakten, bestückt. Auf diese Weise können zwei solche Steckverbinder als Stecker und Gegenstecker ausgebildet sein und zur Übertragung pneumatischer Signale zusammengefügt werden. Dann wirkt zum einen auf jeden der beiden dazugehörigen Halterahmen, nämlich den Halterahmen des Steckers und den Halterahmen des Gegensteckers, bereits durch den Luftdruck eine entsprechende Kraft. Weiterhin wird auch durch die pneumatischen Module ein ständiger Druck auf die beiden Halterahmen erzeugt, da deren pneumatische Kontakte unter einem ständigen mechanischen Anpressdruck stehen. Auch diesen Anpressdruck müssen schließlich die beiden Halterahmen aufbringen, wodurch zusätzlich ständige Kräfte auf sie wirken. A disadvantage of this prior art is that such a support frame, if it is simultaneously equipped with a plurality of pneumatic modules and is used in operation in a correspondingly high degree for air pressure transmission, is exposed to correspondingly high forces. The pneumatic modules are equipped with pneumatic contacts, eg pin and / or socket contacts. In this way, two such connectors may be formed as a plug and mating connector and assembled to transmit pneumatic signals. Then acts on the one on each of the two associated holding frame, namely the holding frame of the plug and the holding frame of the mating connector, already by the air pressure a corresponding force. Furthermore, a constant pressure on the two support frame is produced by the pneumatic modules, since the pneumatic contacts are under a constant mechanical contact pressure. Also, this contact pressure must finally muster the two holding frame, as a result of which additional permanent forces act on them.
Durch eine damit verbundene, unter dieser Last langsam fortschreitende Deformation („Kriechen") der Halterahmen werden die Module nach einem bestimmten Zeitraum unter ständiger Belastung zumindest nicht mehr an allen erforderlichen Stellen mit dem notwendigen Druck gegeneinander gepresst, was dazu führt, dass zwischen den Modulen zumindest an einigen Stellen Luft entweicht. Dadurch sinkt der übertragene Luftdruck in den entsprechenden Kanälen und die Qualität der pneumatischen Signalübertragung verschlechtert sich erheblich. By an associated, under this load slowly progressive deformation ("creeping") of the support frame, the modules are pressed after a certain period of time under constant load at least not at all required locations with the necessary pressure against each other, resulting in that between the modules As a result, the air pressure transmitted in the corresponding channels drops and the quality of the pneumatic signal transmission deteriorates considerably.
Aufgabenstellung task
Die Aufgabe der Erfindung besteht somit darin, diesen Nachteil zu überwinden und einen Halterahmen anzugeben, der eine ausreichende Stabilität gegen eine solche Verformung besitzt. The object of the invention is thus to overcome this disadvantage and to provide a holding frame which has sufficient stability against such deformation.
Diese Aufgabe wird mit einem Halterahmen der eingangs erwähnten Art durch die Merkmale des kennzeichnenden Teils des unabhängigen Hauptanspruchs 1 gelöst. This object is achieved with a support frame of the type mentioned by the features of the characterizing part of the independent main claim 1.
Bei einem solchen Halterahmen handelt es sich um einen Bestandteil eines Steckverbinders, wobei der Halterahmen besonders gut dazu geeignet ist, Module, insbesondere pneumatische Module, aufzunehmen und in dem Steckverbinder zu fixieren. Der Steckverbinder ist dafür vorgesehen, beispielsweise mit einem weiteren derartigen Steckverbinder zusammengesteckt zu werden, um durch die pneumatischen Module pneumatische Signale möglichst verlustfrei zu übertragen. Unter dem Begriff„pneumatische Module" sind dabei Module zu verstehen, die von dem Halterahmen gehalten werden können und die jeweils mindestens einen pneumatischen Kanal, bevorzugt zwei oder drei pneumatische Kanäle, beispielsweise in Form von Durchgangsöffnungen, aufweisen, wodurch sie dazu geeignet sind, den Druck eines Gases oder Gasgemisches, insbesondere eines Luftstroms, zu übertragen. Dazu ist es vorgesehen, pneumatische Stift- und/oder Buchsenkontakte in den pneumatischen Kanälen anzuordnen. In such a support frame is a part of a connector, wherein the support frame is particularly well suited to receive modules, in particular pneumatic modules, and to fix in the connector. The connector is intended to be mated with another such connector, for example, to transmit as little loss through the pneumatic modules pneumatic signals. The term "pneumatic modules" are understood to mean modules that can be held by the holding frame and at least each a pneumatic channel, preferably two or three pneumatic channels, for example in the form of passage openings, whereby they are suitable for transmitting the pressure of a gas or gas mixture, in particular an air stream. For this purpose it is provided to arrange pneumatic pin and / or socket contacts in the pneumatic channels.
Durch die Verwendung eines erfindungsgemäßen Halterahmens kann die Zahl der pneumatischen Module, mit denen er bestückt ist, größer sein, als dies im Stand der Technik üblich ist, weil ein solcher Halterahmen der deformierenden Kraft, die durch den übertragenen Luftdruck entsteht, eine gegenüber dem Stand der Technik erhöhte Stabilität entgegensetzt. Somit kann der Halterahmen nicht nur mit einem oder zwei sondern sogar mit drei, vier oder fünf oder mehr pneumatischen Modulen bestückt sein. Beispielsweise kann ein Halterahmen, der beispielsweise zur Aufnahme von sechs Modulen vorgesehen ist, vollständig mit pneumatischen Modulen bestückt sein. By using a holding frame according to the invention, the number of pneumatic modules with which it is equipped, be greater than is usual in the prior art, because such a holding frame of the deforming force, which is caused by the transmitted air pressure, one with respect to the state the technique provides increased stability. Thus, the support frame can be equipped not only with one or two but even with three, four or five or more pneumatic modules. For example, a holding frame, which is provided for example for receiving six modules, be fully equipped with pneumatic modules.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments of the invention are specified in the subclaims.
Ein wesentlicher Vorteil der Erfindung besteht darin, dass der Halterahmen wesentlich bessere Kriecheigenschaften aufweist, als ein vergleichbarer Halterahmen, der beispielsweise aus Zink gefertigt ist. Mit anderen Worten ist seine Deformation unter einer ständigen Belastung mit dem üblicherweise zu übertragenden Luftdruck bei einer vorgegebenen Betriebstemperatur deutlich geringer, wie sowohl in entsprechenden Simulationen als auch in einigen aufwändigen Messungen herausgefunden und bestätigt werden konnte. Jedes dieser Halterahmenteile besteht somit aus Blech und insbesondere, um einen guten Korrosionsschutz zu gewährleisten, aus einem Edelstahlblech, so dass es sich bei den beiden Halterahmenteilen um zwei Blechteile handelt. Besonders bevorzugt kann dafür Edelstahl der Kennziffer 1 .4301 (X5CrNi18-10) verwendet werden, früher auch bekannt unter dem Namen V2A. A significant advantage of the invention is that the support frame has significantly better creep properties than a comparable support frame, which is made of zinc, for example. In other words, its deformation under a constant load with the usually to be transmitted air pressure at a given operating temperature is significantly lower, as could be found and confirmed both in corresponding simulations and in some expensive measurements. Each of these holder frame parts thus consists of sheet metal and, in particular, in order to ensure good corrosion protection, of a stainless steel sheet, so that the two holder frame parts are two sheet metal parts. Particularly preferably, stainless steel number 1 .4301 (X5CrNi18-10) can be used, formerly also known under the name V2A.
Die Verwendung von Blech hat darüber hinaus den Vorteil, dass zur Herstellung solcher Blechteile in der sogenannten„Stanzbiegetechnik" gegenüber beispielswiese einem Druckgussverfahren, z.B. dem Zinkdruckgussverfahren, keine speziellen, entsprechend teuren Werkzeuge notwendig sind. Beispielsweise gewährleistet die Verwendung von hochwertigem Edelstahl weiterhin einen guten Korrosionsschutz, ohne dass dabei eine zusätzliche Oberflächenbeschichtung notwendig ist. The use of sheet metal also has the advantage that no special, correspondingly expensive tools are necessary for the production of such sheet metal parts in the so-called "stamping and bending technique" compared to, for example, a die casting process without requiring an additional surface coating.
Das Blech, aus dem die Blechteile bestehen, kann eine Stärke von mindestens 0,5 mm, bevorzugt mindestens 1 mm, insbesondere mindestens 1 ,5 mm, beispielsweise 2 mm aufweisen. The sheet metal from which the sheet metal parts are made may have a thickness of at least 0.5 mm, preferably at least 1 mm, in particular at least 1.5 mm, for example 2 mm.
Jedes der Blechteile kann jeweils ein Seitenteil aufweisen, in dem mehrere insbesondere zueinander gleichartige Fenster angeordnet sind. Die Fenster dienen dazu, dafür vorgesehene Haltenasen der Module aufzunehmen, um die Module dadurch im Halterahmen zu fixieren. Each of the sheet metal parts may each have a side part in which a plurality of windows, in particular similar to each other, are arranged. The windows are used to receive designated retaining lugs of the modules in order to fix the modules in the support frame.
In einer bevorzugten Ausgestaltung unterscheiden sich die beiden Blechteile voneinander zumindest durch die Größe und/oder die Form ihrer Fenster. Dies hat den Vorteil, dass dadurch die Orientierung jedes pneumatischen Moduls, das dementsprechend auch zwei verschiedene, den jeweiligen Fenstern entsprechende Haltenasen aufweist, festgelegt ist. Mit anderen Worten können die Fenster der Blechteile und die Haltenasen der Module durch ihre Form und / oder Größe als Kodiermittel zur Orientierung der Module verwendet werden. In a preferred embodiment, the two sheet metal parts differ from each other at least by the size and / or the shape of their windows. This has the advantage that thereby the orientation of each pneumatic module, which accordingly also has two different retaining lugs corresponding to the respective windows, is defined. In other words, the windows of the sheet metal parts and the retaining lugs of the Modules are used by their shape and / or size as coding for orientation of the modules.
In einer alternativen vorteilhaften Ausgestaltung kann der Halterahmen aus zwei zueinander gleichartigen Blechteilen gebildet sein. Diese Ausgestaltung besitzt den Vorteil, dass sich der Herstellungsprozess vereinfacht und die Herstellungskosten dadurch gesenkt werden können. In an alternative advantageous embodiment, the holding frame may be formed from two similar sheet metal parts. This embodiment has the advantage that the manufacturing process can be simplified and the manufacturing costs can be reduced thereby.
In einer bevorzugten Ausgestaltung weist jedes Blechteil an zwei einander gegenüberliegenden Enden seines Seitenteils jeweils einen rechtwinklig abgewinkelten, insbesondere abgebogenen, Endbereich auf. Jeder dieser abgewinkelten Endbereiche kann an seinem Ende einen Kontaktbereich mit einer dazugehörigen Kontaktfläche zum Anfügen und zur mechanischen Befestigung an dem Kontaktbereich des jeweils anderen Blechteils besitzen. Insbesondere kann dieser Kontaktbereich mit seiner Kontaktfläche zu seinem jeweiligen Endbereich rechtwinklig abgewinkelt, insbesondere abgebogen, und somit wieder parallel zu der Seitenfläche des jeweiligen Blechteils ausgerichtet sein. Jeder Kontaktbereich kann eine Schraubbohrung oder eine Schrauböse aufweisen. Die Schraubbohrung zeichnet sich dadurch aus, dass sie ein Innengewinde besitzt. Die Schrauböse zeichnet sich dadurch aus, dass sie einen größeren Durchmesser als die Schraubbohrung besitzt. Die Kontaktflächen der Kontaktbereiche können bevorzugt eine Größe von beispielsweise mindestens 25 mm2 , bevorzugt mindestens 30 mm2, besonders bevorzugt mindestens 35 mm2 und insbesondere mindestens 40 mm2 besitzen. Weiterhin kann die Kontaktfläche im Wesentlichen rechteckig oder quadratisch sein, wobei jede Kante vorteilhafterweise länger ist als 4 mm, bevorzugt 5 mm. Dabei beinhaltet der Begriff„im Wesentlichen rechteckig oder quadratisch", dass ihre Ecken abgerundet sein können. Durch ein Gegeneinanderpressen ihrer jeweiligen Kontaktbereiche an ihren Kontaktflächen, z.B. durch eine Ver- schraubung, können die beiden Blechteile mit einer besonders großen Stabilität aneinander gehalten sein. Zur Verschraubung kann eine Schraube durch die Schrauböse eines Kontaktbereichs des einen Blechteils geführt und in die Schraubbohrung eines Kontaktbereichs des jeweils anderen Blechteils geschraubt sein. In a preferred embodiment, each sheet metal part at two opposite ends of its side part in each case a right angle angled, in particular bent, end region. Each of these angled end regions may have at its end a contact region with an associated contact surface for attachment and for mechanical attachment to the contact region of the respective other sheet metal part. In particular, this contact region can be bent at right angles with its contact surface to its respective end region, in particular bent, and thus aligned again parallel to the side surface of the respective sheet metal part. Each contact area can have a screw hole or a screw eye. The screw hole is characterized in that it has an internal thread. The screw eye is characterized in that it has a larger diameter than the screw hole. The contact surfaces of the contact regions may preferably have a size of, for example, at least 25 mm 2 , preferably at least 30 mm 2 , particularly preferably at least 35 mm 2 and in particular at least 40 mm 2 . Furthermore, the contact surface can be substantially rectangular or square, wherein each edge is advantageously longer than 4 mm, preferably 5 mm. The term "essentially rectangular or square" implies that their corners may be rounded off by pressing their respective contact areas against one another at their contact surfaces, for example by means of a connection. gland, the two sheet metal parts can be held together with a particularly high stability. For screwing a screw can be passed through the eyelet of a contact portion of a sheet metal part and screwed into the screw hole of a contact region of the other sheet metal part.
Die Verwendung von Blech als Werkstoff und die gleichzeitige Ausführung der Blechteile mit einem solchen Kontaktbereich besitzt dabei einen besonders großen Synergieeffekt. Besonders vorteilhaft ist dabei nämlich, dass der Halterahmen durch die gegenseitige Verschraubung seiner Blechteile an ihren Haltebereichen eine besonders große Stabilität gegen ein Verschwenken der Blechteile gegeneinander um seine Mittelachse, die parallel zum Seitenteil und durch die Halteflächen verläuft, aufweist. Ein Grund dafür liegt darin, dass die Haltebereiche sowie deren Schraubbohrungen auch langfristig unter mechanischer Spannung und Druck wesentlich geringere„Kriecheigenschaften" aufweisen, als dies vergleichsweise bei einem Aluminiumdruckgussgehäuse der Fall ist. The use of sheet metal as a material and the simultaneous execution of the sheet metal parts with such a contact area thereby has a particularly large synergy effect. Namely, it is particularly advantageous that the holding frame by the mutual screwing of its sheet metal parts at their holding areas a particularly great stability against pivoting of the sheet metal parts against each other about its central axis, which is parallel to the side part and through the support surfaces has. One reason for this is that the holding areas and their screw holes have much lower "creep properties" even under long-term mechanical stress and pressure than is the case comparatively with an aluminum die-cast housing.
Weiterhin kann an jedem Endbereich jedes Bleichteils eine Fußfläche mit einer weiteren Schraubbohrung zur Verschraubung mit einem Steckverbindergehäuse vorgesehen sein. Die Fußfläche kann rechtwinklig zu dem jeweiligen Endbereich und rechtwinklig zu dem Seitenteil ausgerichtet sein. Furthermore, at each end region of each bleaching part a foot surface can be provided with a further screw hole for screwing to a connector housing. The foot surface may be oriented at right angles to the respective end region and at right angles to the side part.

Die Fig. 1 zeigt ein erstes Blechteil 1 in einer Seitenansicht. Das Blechteil 1 besitzt ein Seitenteil 1 1 mit sechs Fenstern 12, die auf dem Seitenteil 1 1 mit den Buchstaben A, B, C, D, E, und F bezeichnet sind. Die Fenster 12 sind dazu vorgesehen, erste Haltenasen 21 , 31 von Modulen, insbesondere von pneumatischen Modulen 2, 3, wie sie beispielsweise in Fig. 4 dargestellt werden, aufzunehmen und diese Module 2, 3 dadurch zu fixieren. Die Endbereiche 13 des Blechteils 1 sind aus dieser Perspektive nicht zu sehen. Dagegen sind zwei Kontaktbereiche 14 zu erkennen. Die Kontaktbereiche 14 besitzen eine Schrauböse 143, die in dieser Darstellung von der hindurchgesteckten Schraube 142 verdeckt ist. Die Schrauböse 143 ist jedoch in Fig. 5 b besonders gut zu sehen. Weiterhin sind zwei Fußflächen 15 zur Befestigung in oder an einem nicht in der Zeichnung dargestellten Steckverbindergehäuse zu sehen. Jede Fußfläche 15 besitzt dazu eine weitere Schraubbohrung, durch die es mit einer Schraube an dem Steckverbindergehäuse verschraubt werden kann, wobei diese weiteren Schraubbohrungen aus dieser Ansicht nicht zu sehen sind und wobei die dazugehörigen weiteren Schrauben nicht mit Bezugszeichen versehen sind. Fig. 1 shows a first sheet metal part 1 in a side view. The sheet metal part 1 has a side part 1 1 with six windows 12, which are designated on the side part 1 1 with the letters A, B, C, D, E, and F. The windows 12 are intended to receive first retaining lugs 21, 31 of modules, in particular of pneumatic modules 2, 3, as shown for example in FIG. 4, and thereby to fix these modules 2, 3. The end portions 13 of the sheet metal part 1 are not visible from this perspective. In contrast, two contact areas 14 can be seen. The contact areas 14 have a screw eye 143, which is covered in this illustration by the inserted screw 142. However, the screw eye 143 is shown particularly clearly in FIG. 5 b. Furthermore, two feet 15 can be seen for attachment in or on a connector housing not shown in the drawing. Each foot surface 15 has for this purpose a further screw hole through which it can be screwed to the connector housing with a screw, said further screw holes are not visible from this view and wherein the associated further screws are not provided with reference numerals.
Die Fig. 2 zeigt das erste Blechteil 1 zusammen mit einem zweiten Blech- teil 1 ', wobei die beiden Blechteile 1 , 1 ' zu einem Halterahmen zusammengeschraubt sind. Dabei sind deren jeweiligen Seitenteile 1 1 , 1 1 ' mit ihren beiden jeweils daran anschließenden rechtwinklig abgewinkelten Endbereichen 13, 13' dargestellt. Jeder dieser abgewinkelten Endbereiche 13, 13' besitzt an seinem freien Ende eine Kontaktbereich 14, 14'. Diese Kontaktbereiche 14, 14' sind zu ihrem jeweiligen Endbereich 13, 13' rechtwinklig abgewinkelt, insbesondere abgebogen, und somit wieder parallel zu der Seitenfläche 1 1 , 1 1 ' ausgerichtet. Mittels einer Schraube 142 werden die Kontaktbereiche 14, 14' der beiden Blechteile 1 , 1 ' gegeneinander gepresst und die Blechteile 1 , 1 ' werden somit besonders stabil aneinander gehalten. Weiterhin besitzt jedes Blechteil 1 , 1 ' zwei Fußflächen 15, 15'. Durch die nicht sichtbaren weiteren Schraubbohrungen, die sich in diesen Fußflächen 15, 15' befinden, verlaufen weitere Schrauben. Diese nicht mit Bezugszeichen versehenen, weiteren Schrauben dienen dazu, den gesamten Halterahmen seinerseits in einem nicht in der Zeichnung dargestellten Steckverbindergehäuse zu fixieren. 2 shows the first sheet metal part 1 together with a second sheet metal part. part 1 ' , wherein the two sheet metal parts 1, 1 ' are screwed together to form a holding frame. In this case, their respective side parts 1 1, 1 1 ' with their two adjoining thereto right angled end portions 13, 13 ' are shown. Each of these angled end portions 13, 13 ' has at its free end a contact region 14, 14 ' . These contact areas 14, 14 'are at their respective end portion 13, 13' perpendicularly angled, in particular bent, and thus again parallel to the side surface 1 1, aligned 1 1 '. By means of a screw 142, the contact areas 14, 14 'of the two sheet metal parts 1, 1 ' pressed against each other and the sheet metal parts 1, 1 ' are thus held particularly stable together. Furthermore, each sheet metal part 1, 1 'has two foot surfaces 15, 15 ' . Due to the non-visible further screw holes, which are located in these foot surfaces 15, 15 ' , run further screws. These not provided with reference numerals, other screws serve to fix the entire support frame in turn in a connector housing not shown in the drawing.
Die Fig. 3 zeigt den Halterahmen in einem unverschraubten Zustand in einer 3D-Ansicht. Dadurch sind in dieser Darstellung die Schraubbohrung 141 sowie beide Seitenflächen 1 1 , 1 1 ' mit jeweils mehreren Fenstern 12, 12' sehr gut zu sehen. Die beiden Blechteile 1 , 1 ' unterscheiden sich im Wesentlichen durch die Form und Größe ihrer Fenster 12, 12'. Insbesondere können die beiden Blechteile 1 , 1 ' zur Verbesserung der Korrosionsbeständigkeit aus Edelstahl gefertigt sein und weisen beispielsweise eine Wandstärke von mindestens 0,5 mm, bevorzugt mindestens 1 mm, insbesondere mindestens 1 ,5 mm, also beispielsweise 2 mm auf, wodurch ein hohes Maß an Stabilität gegen eine Verformung bei Einwirkung ständiger äußerer Kräfte gewährleistet ist. An zwei Enden seiner Seitenfläche 1 1 , 1 1 ' ist das jeweilige Blechteil 1 , 1 ' rechtwinklig abgewinkelt, insbesondere abgebogen, wobei die äußeren Kanten vorteilhafterweise abgerundet sind. Die dadurch abgewinkelten Endbereiche 13, 13' können an ihren oben beschriebenen Kontaktbereichen 14, 14' in der bereits erwähnten Weise aneinander verschraubt werden. Dabei ist in dieser Darstellung insbesondere der Kontaktbereich 14' des ersten Blechteils 1 ' mit seiner Schraubbohrung 141 besonders gut zu sehen. 3 shows the holding frame in an unscrewed state in a 3D view. Thus, in this illustration, the screw hole 141 and both side surfaces 1 1, 1 1 ' , each with a plurality of windows 12, 12 ' to see very well. The two sheet metal parts 1, 1 ' differ essentially by the shape and size of their windows 12, 12 ' . In particular, the two sheet metal parts 1, 1 ' can be made of stainless steel to improve the corrosion resistance and have for example a wall thickness of at least 0.5 mm, preferably at least 1 mm, in particular at least 1, 5 mm, for example 2 mm, whereby a high Level of stability against deformation under the influence of constant external forces is guaranteed. At two ends of its side surface 1 1, 1 1 ' is the respective sheet metal part 1, 1 ' angled at right angles, in particular bent, the outer edges are advantageously rounded. The thereby angled end portions 13, 13 ' can be screwed together at their above-described contact areas 14, 14 ' in the manner already mentioned. In this case, in particular the contact region 14 'of the first sheet-metal part 1 ' with its screw hole 141 can be seen particularly well in this illustration.
Die Fig. 4 zeigt in zwei Ansichten ein erstes pneumatisches Modul 2, das zwei Kanäle 23 aufweist sowie in weiteren zwei Ansichten ein zweites pneumatisches Modul 3, das drei Kanäle 33 aufweist. Bei den Kanälen 23, 33 handelt es sich um im Wesentlichen zylindrische Durchgangsöffnungen der pneumatischen Module 2, 3. Die Kanäle 23, 33 dienen der Aufnahme nicht in der Zeichnung dargestellter männlicher und/oder weiblicher pneumatischer Kontakte. Jedes der beiden pneumatischen Module 2, 3 ist im Wesentlichen Quaderförmig ausgebildet und besitzt an einander gegenüberliegenden Seiten jeweils eine Haltenase 21 , 21 ' 31 , 31 ', nämlich jeweils eine erste Haltenase 21 , 31 an der einen Seite sowie jeweils eine zweite Haltenase 21 ', 31 ' an der jeweils gegenüber liegenden Seite, wobei sich die ersten Haltenasen 21 , 31 und die zweiten Haltenasen 21 ', 31 ' von einander in ihrer Form und Länge unterscheiden. Diese Haltenasen sind jeweils in eines der Fenster 12, 12' eines der Blechteile 1 , 1 ' einfügbar, wobei sich auch diese Fenster 12, 12' voneinander in Form und Länge unterscheiden. Die ersten Haltenasen 21 , 31 sind entweder formschlüssig in die Fenster 12 des ersten Blechteils 1 einfügbar oder zumindest derart in die Fenster 12 des ersten Blechteils 1 einfügbar, dass sie bezüglich der Ebene des dazugehörigen Seitenteils 1 1 in dessen Fenstern 12 fixiert sind. Die zweiten Haltenasen 21 ', 31 ' sind entweder formschlüssig in die Fenster 12' des zweiten Blechteils 1 ' einfügbar oder zumindest derart in die Fenster 12' des zweiten Blechteils 1 ' einfügbar, dass sie bezüglich der Ebene seines Seitenteils 1 1 ' in dessen Fenstern 12' fixiert sind. FIG. 4 shows in two views a first pneumatic module 2, which has two channels 23, and in a further two views, a second pneumatic module 3, which has three channels 33. The channels 23, 33 are substantially cylindrical passage openings of the pneumatic modules 2, 3. The channels 23, 33 serve to accommodate not shown in the drawing male and / or female pneumatic contacts. Each of the two pneumatic modules 2, 3 is formed substantially cuboid-shaped and has on opposite sides in each case one retaining lug 21, 21 '31, 31', namely, respectively, a first retaining tab 21, 31 on one side and in each case a second retaining tab 21 ' , 31 ' on the respective opposite side, wherein the first retaining lugs 21, 31 and the second retaining lugs 21 ' , 31 ' differ from each other in their shape and length. These retaining lugs can each be inserted into one of the windows 12, 12 'of one of the sheet-metal parts 1, 1 ' , whereby these windows 12, 12 'also differ from each other in shape and length. The first retaining lugs 21, 31 are either form-fitting inserted into the window 12 of the first sheet metal part 1 or at least so inserted into the window 12 of the first sheet metal part 1, that they are fixed relative to the plane of the associated side part 1 1 in its windows 12. The second retaining lugs 21 ' , 31 ' are either form-fitting inserted into the window 12 'of the second sheet metal part 1 ' or at least so inserted into the window 12 'of the second sheet metal part 1 ' , that they with respect to the plane of its side part 1 1 ' in its windows 12 'are fixed.
Weiterhin besitzt jedes pneumatische Modul 2, 3 vier federelastische Rastarme 22, 32, an deren freistehenden Enden Haken 221 , 321 angeformt sind. Die Rastarme 22, 32 sind dazu geeignet, eine zusätzliche Stabilität zu erzeugen, wenn die Module 2, 3 in den Halterahmen eingebaut sind und gleichzeitig eine geometrische Toleranz der Abmessungen der Module 2, 3 zu gewährleisten. Im Wesentlichen sind die Rastarmen 22, 32 aber zur Kompatibilität der pneumatischen Module 2, 3 mit anderen Halterahmen vorgesehen, so dass vorteilhafterweise dieselben pneumatischen Module 2, 3 verwendet werden können, die bereits in anderen Halterahmen-Systemen Anwendung finden. Diese Rastarme 22, 32 sind schließlich zum Fixieren der pneumatischen Module 2, 3 in dem Halterahmen nicht zwingend erforderlich, insbesondere, wenn die Blechteile 1 , 1 ' entsprechende federelastische Eigenschaften aufweisen und sich somit der Form der pneumatischen Module 2, 3 zumindest geringfügig anpassen können und diese dadurch auch über einen längeren Zeitraum unter einer federelastischen Spannung zu halten in der Lage sind, ohne sich dabei selbst irreversibel zu verformen, zu kriechen, oder ähnlich zu verändern. Furthermore, each pneumatic module 2, 3 has four spring-elastic Locking arms 22, 32, at the free-standing ends hooks 221, 321 are formed. The latching arms 22, 32 are adapted to produce additional stability when the modules 2, 3 are installed in the support frame and at the same time to ensure a geometric tolerance of the dimensions of the modules 2, 3. In essence, however, the locking arms 22, 32 are provided for compatibility of the pneumatic modules 2, 3 with other support frames, so that advantageously the same pneumatic modules 2, 3 can be used, which are already used in other support frame systems. Finally, these latching arms 22, 32 are not absolutely necessary for fixing the pneumatic modules 2, 3 in the holding frame, in particular if the sheet metal parts 1, 1 'have corresponding elastic properties and can thus at least slightly adapt to the shape of the pneumatic modules 2, 3 and thereby be able to hold them under a resilient tension for a long period of time without irreversibly deforming, crawling, or otherwise changing themselves.
Die Fig.5 a zeigt die beiden einzelnen Blechteile 1 , 1 ' und die dazwischen angeordneten ersten und zweiten pneumatischen Module 2, 3 in einer Explosionsdarstellung. Die Fig. 5 b zeigt daraus eine Vergrößerung zweier Kontaktbereiche 14, 14' der beiden Blechteile. Darin sind die Kontaktbereiche 14, 14' mit ihrer Schraubbohrung 141 bzw. ihrer Schrauböse 143 besonders gut zu erkennen. FIG. 5a shows the two individual sheet-metal parts 1, 1 ' and the first and second pneumatic modules 2, 3 arranged therebetween in an exploded view. FIG. 5 b shows an enlargement of two contact regions 14, 14 'of the two sheet-metal parts. Therein, the contact areas 14, 14 ' with their screw hole 141 or their screw eye 143 can be seen particularly well.
Jeder Kontaktbereich 14, 14' weist entweder eine Schraubbohrung 141 , oder eine Schrauböse 143 auf. Insbesondere weisen die Kontaktbereiche 14 des ersten Steckverbinderteils 1 eine Schrauböse 143 auf und die Kontaktbereiche 14' des zweiten Steckverbinderteils 1 ' weisen eine Schraubbohrung 141 auf, wobei sich die Schraubbohrung 141 durch einen kreisrunden Querschnitt sowie durch ein Innengewinde auszeichnet. Each contact region 14, 14 ' has either a screw hole 141, or a screw eye 143. In particular, the contact regions 14 of the first connector part 1 have a screw eye 143 and the contact regions 14 'of the second connector part 1 ' have a screw hole 141, wherein the screw hole 141 through a circular cross section and characterized by an internal thread.
Aneinander befestigt werden die beiden Blechteile 1 , 1 ' durch eine Schraube 142, welche zunächst durch die jeweilige Schrauböse 143 eines der Blechteile 1 geführt und dann in die Schraubbohrung 141 des jeweils anderen Blechteils 1 geschraubt ist und die somit die beiden Blechteile 1 , 1 ' an ihren Kontaktbereichen 14, 14' aneinander fixiert. Dazu ist besitzt die Schraubbohrung 141 ein Innengewinde. Die The two sheet-metal parts 1, 1 ' are fastened together by a screw 142, which is first guided through the respective screw eye 143 of one of the sheet metal parts 1 and then screwed into the screw hole 141 of the respective other sheet metal part 1 and thus the two sheet metal parts 1, 1 '. fixed to one another at their contact areas 14, 14 ' . For this purpose, the screw hole 141 has an internal thread. The
Schrauböse 143 kann zum Toleranzausgleich als Langloch ausgebildet sein. Screw eye 143 may be formed to compensate for tolerances as a slot.
Der Synergieeffekt der Verwendung von Blech als Werkstoff und die gleichzeitige Ausführung der Blechteile 1 , 1 ' mit einem solchen Kontaktbereich 14, 14' ist dabei besonders gut erkennbar, da der Halterahmen durch die gegenseitige Verschraubung der Blechteile 1 , 1 ' an diesen Haltebereichen 14, 14' eine besonders große Stabilität gegen ein Verschwenken der Blechteile 1 , 1 ' gegeneinander aufweist. Dabei ist zu beachten, dass die Blechteile 1 , 1 ' bevorzugt eine Stärke von mindestens 0,5 mm, besonders bevorzugt mindestens 1 mm, insbesondere mindestens 1 ,5 mm, also beispielsweise 2 mm aufweisen. The synergy effect of the use of sheet metal as a material and the simultaneous execution of the sheet metal parts 1, 1 ' with such a contact region 14, 14 ' is particularly well recognizable because the support frame by the mutual screwing the sheet metal parts 1, 1 ' at these holding areas 14, 14 'has a particularly high stability against pivoting of the sheet metal parts 1, 1 ' against each other. It should be noted that the sheet metal parts 1, 1 ' preferably have a thickness of at least 0.5 mm, more preferably at least 1 mm, in particular at least 1, 5 mm, so for example 2 mm.
Die Fig. 6 zeigt einen Halterahmen, umfassend zwei zusammengeschraubte Blechteile 1 , der vollständig mit den ersten und zweiten pneumatischen Modulen 2, 3 bestückt ist. Die Haltenasen 21 , 21 ', 31 , 31 ' der pneumatischen Module 2, 3 sind in die jeweiligen Fenster 12, 12' eingefügt, so dass sie im Halterahmen fixiert sind. Aus dieser Ansicht sind allerdings nur die zweiten Haltenasen 21 ', 31 ' und die Fenster 12' des zweiten Blechteils 1 ' zu sehen. Die beiden Blechteile 1 , 1 ' sind an ihren Kontaktbereichen 14 mit jeweils einer Schraube 142 in der oben beschriebenen Weise zusammengeschraubt. Dadurch werden die Kontaktbereiche 14, 14' gegeneinander gepresst und sorgen für eine stabile mechanische Verbindung der beiden Blechteile 1, 1'. Weiterhin stehen die Rastarme 22, 22', 32, 32' der pneumatischen Module durch die zusammengeschraubten Blechteile 1, 1' unter mechanischer Spannung und drücken gleichzei- tig gegen beide Blechteile 1, 1', wodurch die Module 2, 3 zusätzlich im Halterahmen zwischen den beiden Blechteilen 1 fixiert sind. FIG. 6 shows a holding frame comprising two sheet metal parts 1 bolted together, which is completely equipped with the first and second pneumatic modules 2, 3. The retaining lugs 21, 21 ' , 31, 31 ' of the pneumatic modules 2, 3 are inserted into the respective windows 12, 12 ' , so that they are fixed in the holding frame. From this view, however, only the second retaining lugs 21 ' , 31 ' and the window 12 'of the second sheet metal part 1 ' can be seen. The two sheet metal parts 1, 1 ' are screwed together at their contact areas 14, each with a screw 142 in the manner described above. As a result, the contact areas 14, 14 ' pressed against each other and ensure a stable mechanical connection of the two sheet metal parts 1, 1 ' . Furthermore, the latching arms 22, 22 ' , 32, 32 ' of the pneumatic modules by the bolted sheet metal parts 1, 1 ' under mechanical tension and press simultane- ously against both sheet metal parts 1, 1 ' , whereby the modules 2, 3 additionally in the holding frame between the two sheet metal parts 1 are fixed.
