Description

Die vorliegende Erfindung betrifft eine Vakuumpumpe nach dem Oberbegriff des Anspruchs 1, wie sie zum Beispiel durch die US 2002/0094277 A1 offenbart ist, und ein Verfahren zur Herstellung einer Vakuumpumpe nach dem Oberbegriff des Anspruchs 15, wie es z.B. in der EP 1 843 043 A2 offenbart ist.The present invention relates to a vacuum pump according to the preamble of claim 1, as for example by the US 2002/0094277 A1 is disclosed, and a method for producing a vacuum pump according to the preamble of claim 15, as it is for example in the EP 1 843 043 A2 is disclosed.

Eine beispielhafte Vakuumpumpe umfasst einen Motor, der innen in einem Gehäuse der Vakuumpumpe angeordnet ist, und eine Steuereinheit für den Motor, die außen an dem Gehäuse angeordnet ist. Dabei muss das Gehäuse zur Bewahrung eines Vakuums in dem Gehäuse gegenüber einem äußeren Bereich abgedichtet werden, während gleichzeitig eine elektrische Verbindung zwischen dem Motor und der Steuereinheit notwendig ist.An exemplary vacuum pump comprises a motor, which is arranged inside in a housing of the vacuum pump, and a control unit for the motor, which is arranged on the outside of the housing. In order to maintain a vacuum in the housing, the housing must be sealed off from an outer region, while at the same time an electrical connection between the motor and the control unit is necessary.

Im Stand der Technik wird bei einem beispielhaften Verfahren zur Herstellung einer solchen Vakuumpumpe der Motor zunächst im Gehäuse angeordnet. Anschließend wird eine Leitung von dem Motor durch eine Öffnung des Gehäuses herausgeführt und die Leitung wird mit einer Anschlusseinheit für die Steuereinheit außerhalb des Gehäuses elektrisch verbunden, z.B. verlötet. Die Anschlusseinheit wird dann von außen an dem Gehäuse befestigt.In the prior art, in an exemplary method for producing such a vacuum pump, the motor is first arranged in the housing. Then a line is led out of the motor through an opening in the housing and the line is electrically connected to a connection unit for the control unit outside the housing, e.g. soldered. The connection unit is then attached to the housing from the outside.

Ein Nachteil an diesem Verfahren besteht darin, dass der Motor erst nach der Verbindung mit der Anschlusseinheit abschließend getestet werden kann. Der Motor kann also erst getestet werden, nachdem er in dem Gehäuse der Vakuumpumpe verbaut ist.A disadvantage of this method is that the motor can only be finally tested after it has been connected to the connection unit. The motor can therefore only be tested after it has been installed in the housing of the vacuum pump.

Es ist eine Aufgabe der Erfindung, die Montage einer Vakuumpumpe zu vereinfachen.It is an object of the invention to simplify the assembly of a vacuum pump.

Die Aufgabe wird durch eine Vakuumpumpe mit den Merkmalen des Anspruchs 1 gelöst, und insbesondere dadurch, dass die Öffnung und die Gegeneinheit hinsichtlich ihrer Abmessungen derart aufeinander abgestimmt sind, dass die Gegeneinheit in einer von der Betriebsorientierung verschiedenen Montageorientierung durch die Öffnung hindurchführbar ist.The object is achieved by a vacuum pump with the features of claim 1, and in particular in that the opening and the counter unit are matched to one another in terms of their dimensions such that the counter unit can be passed through the opening in a different mounting orientation from the operational orientation.

Ein Vorteil der Erfindung besteht darin, dass die Funktionseinheit und die Gegeneinheit bereits vor der Montage der Funktionseinheit in dem Gehäuse der Vakuumpumpe elektrisch und/oder informationstechnisch verbunden werden können. Die Funktionseinheit und die Gegeneinheit können somit erstens unabhängig von den restlichen Komponenten viel früher im Herstellungsprozess der Vakuumpumpe getestet werden. Dadurch lassen sich mögliche Fehler unter geringerem Aufwand beheben. Zweitens wird die Montage selbst vereinfacht und beschleunigt, weil z.B. ein thermisches Fügen von der Leitung an die Gegeneinheit während des Montagevorgangs entfallen kann.An advantage of the invention is that the functional unit and the counter unit can be connected electrically and / or in terms of information technology before the functional unit is installed in the housing of the vacuum pump. Firstly, the functional unit and the counter unit can be tested much earlier in the vacuum pump manufacturing process, regardless of the other components. This means that possible errors can be remedied with less effort. Second, the assembly itself is simplified and accelerated because e.g. thermal joining from the line to the counter unit can be omitted during the assembly process.

Insbesondere kann die Verbindung der Leitung an die Gegeneinheit bereits bei der Herstellung in geeigneter Weise gekapselt oder vergossen ausgeführt werden, da die Verbindung später bei der Montage der Vakuumpumpe nicht mehr gelöst zu werden braucht. Dies hat unter anderem den Vorteil, dass die Verbindung sicher und zuverlässig vor äußeren Einflüssen geschützt werden kann und somit dauerhaft geschützt ist.In particular, the connection of the line to the counter-unit can already be encapsulated or cast in a suitable manner during manufacture, since the connection no longer needs to be released later when the vacuum pump is installed. This has the advantage, among other things, that the connection can be safely and reliably protected against external influences and is therefore permanently protected.

Die Funktionseinheit und die Gegeneinheit können also als fertige Komponente der Vakuumpumpe gemeinsam bereitgestellt werden, was die Möglichkeit eröffnet, diese Komponente als Ganzes von einem spezialisierten Hersteller zu beziehen, der selbst einen abschließenden Test der Funktionseinheit vornehmen kann. Außerdem wird durch die Erfindung die Demontage und Reparatur der Vakuumpumpe vereinfacht, da eine gegebenenfalls vorhandene Dichtung z.B. in Form eines O-Rings oder einer Flächendichtung einfach ausgetaucht werden kann, ohne die Gegeneinheit von der Leitung zu trennen.The functional unit and the counter unit can thus be provided together as a finished component of the vacuum pump, which opens up the possibility of purchasing this component as a whole from a specialized manufacturer who can carry out a final test of the functional unit. In addition, the disassembly and repair of the vacuum pump is simplified by the invention, since an existing seal, for example in the form of a O-rings or a surface seal can be easily replaced without disconnecting the counter unit from the line.

Diese Vorteile werden erfindungsgemäß insbesondere auch dann erreicht, wenn die Leitung mit der Gegeneinheit nicht über einen Steckverbinder verbunden ist. In diesem Fall können entsprechende Bauteile eingespart werden, während die Montage noch weiter vereinfacht wird.These advantages are achieved according to the invention in particular when the line is not connected to the counter unit via a plug connector. In this case, corresponding components can be saved, while the assembly is further simplified.

Die Funktionseinheit kann einen Motor für die Vakuumpumpe umfassen. Alternativ oder zusätzlich kann die Funktionseinheit weitere Einrichtungen einer Vakuumpumpe umfassen, wie z.B. Mess- und Überwachungseinrichtungen, Ventile oder andere Aktoren zur Steuerung eines Volumenstromes in der Vakuumpumpe.The functional unit can comprise a motor for the vacuum pump. As an alternative or in addition, the functional unit can comprise further devices of a vacuum pump, such as e.g. Measuring and monitoring devices, valves or other actuators for controlling a volume flow in the vacuum pump.

Eine elektrische und/oder informationstechnische Verbindung kann Mittel zur Übertragung von Leistung und/oder Informationen umfassen, wobei die Mittel z.B. elektrische Leiter und/oder Lichtwellenleiter umfassen können.An electrical and / or information technology connection can comprise means for transmitting power and / or information, the means e.g. may include electrical conductors and / or optical fibers.

Die Öffnung muss von einer Kreisform abweichen. Bei einer Ausführungsform weist die Öffnung zumindest im Wesentlichen eine Rechteckform auf. Der Begriff Form bezieht sich auf eine Grundform, die bei weiteren Ausführungsbeispielen der Erfindung z.B. durch Rundungen oder Fasen oder zusätzliche Ausnehmungen von einer idealen Form, wie einer Rechteckform, abweichen kann.The opening must deviate from a circular shape. In one embodiment, the opening is at least essentially rectangular in shape. The term shape refers to a basic shape, which in further embodiments of the invention e.g. due to curves or chamfers or additional recesses from an ideal shape, such as a rectangular shape.

Bei einer weiteren Ausführungsform der Erfindung weist die Gegeneinheit in der Montageorientierung eine Maximalbreite, eine Maximalhöhe und eine senkrecht zur Ebene der Öffnung verlaufende Länge auf. Dabei ist die Maximalbreite der Gegeneinheit kleiner als eine Breite der Öffnung und die Maximalhöhe der Gegeneinheit ist kleiner als eine Höhe der Öffnung. Die Maximalbreite der Gegeneinheit ist hierbei größer als eine Höhe der Öffnung, und die Länge der Gegeneinheit ist größer als eine Breite der Öffnung.In a further embodiment of the invention, the counter unit in the assembly orientation has a maximum width, a maximum height and a length running perpendicular to the plane of the opening. The maximum width of the counter unit is smaller than a width of the opening and the maximum height of the counter unit is smaller than a height of the opening. The maximum width of the counter unit is larger than a height of the opening, and the length of the counter unit is larger than a width of the opening.

Auch bei dieser auf einer relativ einfachen Geometrie basierenden Ausführungsform kann eine vollständige Abdeckung der Öffnung durch die Gegeneinheit gewährleistet werden. Die Begriffe "Höhe", "Breite" und "Länge" beziehen sich lediglich auf die Ausdehnungen von Öffnung und Gegeneinheit in unterschiedlichen Richtungen. Insbesondere ist der Begriff "Höhe" dabei nicht auf eine vertikale Ausdehnungsrichtung beschränkt, sondern kann z.B. auch eine Ausdehnung in horizontaler Richtung beschreiben, wobei in einem solchen Fall der Begriff "Breite" eine Ausdehnung in vertikaler Richtung beschreiben kann. "Höhe", "Breite" und "Länge" können sich aber auch auf beliebige andere, z.B. schräge, Ausdehnungsrichtungen beziehen.In this embodiment, which is based on a relatively simple geometry, complete coverage of the opening by the counter unit can also be ensured. The terms "height", "width" and "length" only refer to the dimensions of the opening and counter unit in different directions. In particular, the term "height" is not limited to a vertical direction of expansion, but can e.g. also describe an extent in the horizontal direction, in which case the term "width" can describe an extent in the vertical direction. "Height", "Width" and "Length" can also refer to any other, e.g. refer to oblique, expansion directions.

In der Montageorientierung können die Maximalbreite und die Länge der Gegeneinheit von einem plattenförmigen Element definiert sein. Mit anderen Worten kann die Gegeneinheit ein plattenförmiges Element umfassen, welches in Breite und Länge größer ist als weitere Komponenten der Gegeneinheit, sofern derartige weitere Komponenten vorhanden sind. Die Maximalhöhe wird in diesem Fall von einer Dicke des plattenförmigen Elements zusammen mit einer Ausdehnung der weiteren Komponenten in der Ausdehnungsrichtung der Dicke definiert.In the assembly orientation, the maximum width and the length of the counter unit can be defined by a plate-shaped element. In other words, the counter unit can comprise a plate-shaped element, which is larger in width and length than other components of the counter unit, if such additional components are present. In this case, the maximum height is defined by a thickness of the plate-shaped element together with an expansion of the further components in the direction of expansion of the thickness.

Bei einer Ausführungsform ist das plattenförmige Element zumindest im Wesentlichen rechteckig. Die Herstellung der Gegeneinheit wird dadurch vereinfacht.In one embodiment, the plate-shaped element is at least substantially rectangular. This simplifies the manufacture of the counter unit.

Das plattenförmige Element kann eine Trägerplatte sein, die eine oder mehrere weitere Komponenten der Gegeneinheit trägt. Die weiteren Komponenten können z.B. relativ einfache Bauteile, wie beispielsweise ein oder mehrere Anschlusselemente, oder auch komplexere Einrichtungen, wie z.B. eine Steuereinheit für die Funktionseinheit, umfassen. Die Komponenten können an der Trägerplatte jeweils dauerhaft oder lösbar befestigt sein.The plate-shaped element can be a carrier plate which carries one or more further components of the counter unit. The further components can include, for example, relatively simple components, such as one or more connection elements, or also more complex devices, such as a control unit for the functional unit. The components can each be permanently or releasably attached to the carrier plate.

Bei einer weiteren Ausführungsform ist die Trägerplatte als Leiterplatte oder Platine ausgebildet ist, die mit der Leitung verbunden ist. Die Leiterplatte oder Platine kann dabei für weitere Leitungsfunktionen ausgebildet sein und/oder weitere Komponenten, wie z.B. Rechen- oder Steuereinheiten, umfassen und/oder elektrisch verbinden.In a further embodiment, the carrier plate is designed as a printed circuit board or circuit board which is connected to the line. The circuit board or board can be designed for further line functions and / or further components, such as Computing or control units, and / or electrically connect.

Die Gegeneinheit kann zumindest einen mit der Leitung verbundenen Anschlussverbinder umfassen, an den eine mit der Funktionseinheit zu verbindende weitere Funktionseinheit anschließbar ist. Dadurch lässt sich die Gegeneinheit relativ klein ausführen, weil zusätzlich notwendige Komponenten gewissermaßen in die weitere Funktionseinheit "ausgelagert" werden können. Somit ist nur eine kleine Öffnung in der Gehäusewand nötig, durch welche nur eine relativ kleine Gegeneinheit hindurchgeführt werden muss. Der häufig knappe Bauraum in einer Vakuumpumpe kann somit besser ausgenutzt werden. Die weitere Funktionseinheit kann z.B. eine Steuereinheit und/oder ein Netzteil für die Funktionseinheit, z.B. für einen Motor, in dem Gehäuse umfassen.The counter unit can comprise at least one connection connector connected to the line, to which a further functional unit to be connected to the functional unit can be connected. As a result, the counter unit can be designed to be relatively small because the necessary components can be "outsourced" to the other functional unit. Thus, only a small opening in the housing wall is necessary, through which only a relatively small counter unit has to be passed. The often scarce installation space in a vacuum pump can thus be better utilized. The further functional unit can e.g. a control unit and / or a power supply unit for the functional unit, e.g. for an engine in the housing.

Der Anschlussverbinder kann z.B. als Stecker oder als Buchse für eine Buchse bzw. einen Stecker der weiteren Funktionseinheit ausgebildet sein. Der Anschlussverbinder kann an einer in der Betriebsorientierung äußeren Seite der Gegeneinheit angeordnet und mit der Leitung auf der inneren Seite der Gegeneinheit verbunden sein. Ein Anschlussverbinder lässt sich insbesondere mit einer Leiterplatte der Gegeneinheit kombinieren, wobei der Anschlussverbinder zumindest einen Pin aufweisen kann, der durch die Leiterplatte hindurchgeführt wird und auf der inneren Seite der Leiterplatte mit der Leitung verlötet wird. Alternativ oder zusätzlich kann der Anschlussverbinder auf der außen befindlichen Oberfläche der Leiterplatte angebracht sein und durch Leiterbahnen mit der inneren Seite der Leiterplatte verbunden und dort mit der Leitung verbunden sein.The connection connector can be designed, for example, as a plug or as a socket for a socket or a plug of the further functional unit. The connection connector can be arranged on an outer side of the counter unit in the operational orientation and can be connected to the line on the inner side of the counter unit. A connection connector can in particular be combined with a printed circuit board of the counter unit, wherein the connection connector can have at least one pin which is passed through the printed circuit board and is soldered to the line on the inner side of the printed circuit board. Alternatively or additionally, the connection connector can be attached to the outer surface of the printed circuit board and connected to the inner side of the printed circuit board by conductor tracks and connected there to the line.

Bei einer anderen Ausführungsform ist die Gegeneinheit an die Gehäusewand geschraubt. Somit wird eine einfache, lösbare Verbindung der Gegeneinheit mit der Gehäusewand gewährleistet.In another embodiment, the counter unit is screwed to the housing wall. This guarantees a simple, detachable connection of the counter unit to the housing wall.

Zwischen der Gegeneinheit und der Gehäusewand kann eine Dichtung vorgesehen sein.A seal can be provided between the counter unit and the housing wall.

Bei einer Ausführungsform weist die Gehäusewand und/oder die Gegeneinheit eine Vertiefung zur Aufnahme der Dichtung auf. In dieser Vertiefung lässt sich die Dichtung, beispielsweise ein O-Ring, sicher festlegen und z.B. durch Anschrauben der Gegeneinheit an die Gehäusewand definiert komprimieren, um die erforderliche Dichtwirkung zu erzielen.In one embodiment, the housing wall and / or the counter unit has a recess for receiving the seal. The seal, for example an O-ring, can be securely fixed in this recess and e.g. compress by screwing the counter unit onto the housing wall in order to achieve the required sealing effect.

Die Leitung kann flexibel sein. Die Gegeneinheit lässt sich dadurch besonders einfach durch die Öffnung hindurchführen. Insbesondere umfasst die Leitung ein oder mehrere Kabel, die jeweils eine oder mehrere Adern aufweisen können.The management can be flexible. The counter-unit can thus be guided through the opening particularly easily. In particular, the line comprises one or more cables, each of which can have one or more wires.

In einer Weiterbildung ist die Leitung mit der Gegeneinheit unlösbar verbunden. Die Leitung kann mit der Gegeneinheit beispielsweise verlötet und/oder vergossen sein. Dadurch werden die Stabilität der Verbindung und der Schutz vor äußeren Einflüssen verbessert.In a further development, the line is permanently connected to the counter unit. The line can, for example, be soldered and / or potted to the counter unit. This improves the stability of the connection and protection against external influences.

Die Aufgabe wird ferner durch ein Verfahren zur Herstellung einer Vakuumpumpe nach Anspruch 15 gelöst, welches z.B. entsprechend den vorstehend genannten Ausführungsformen der Vorrichtung weiter verbessert werden kann.The object is further achieved by a method for producing a vacuum pump according to claim 15, which e.g. can be further improved according to the above-mentioned embodiments of the device.

Weitere Ausführungsformen sind in den abhängigen Ansprüchen, der Beschreibung und den Figuren angegeben.Further embodiments are specified in the dependent claims, the description and the figures.

In Fig. 1 sind eine Funktionseinheit 12 und eine Gegeneinheit 14 dargestellt, die über drei Leitungen 16 verbunden sind. Die Funktionseinheit 12 kann zum Beispiel einen Motor der Vakuumpumpe umfassen. Die Gegeneinheit 14 umfasst eine als Leiterplatte ausgeführte Trägerplatte 22, die einen Anschlussverbinder 24 trägt. Der Anschlussverbinder 24 ist als Buchse für einen Stecker einer weiteren Funktionseinheit, wie zum Beispiel einem Steuergerät für den Motor der Vakuumpumpe, ausgeführt. Die drei Leitungen 16 sind jeweils mit einem Kontaktpunkt der Buchse des Anschlussverbinders 24 verbunden und z.B. je einer Phase eines elektrischen Antriebs des Motors zugeordnet.In Fig. 1 A functional unit 12 and a counter unit 14 are shown, which are connected via three lines 16. The functional unit 12 can comprise a motor of the vacuum pump, for example. The counter unit 14 comprises a carrier plate 22 designed as a printed circuit board, which carries a connection connector 24. The connector 24 is designed as a socket for a plug of a further functional unit, such as a control unit for the motor of the vacuum pump. The three lines 16 are each connected to a contact point of the socket of the connection connector 24 and, for example, each assigned to a phase of an electric drive of the motor.

Die Trägerplatte 22 weist eine Rechteckform auf, deren vier Ecken zur besseren Handhabung der Gegeneinheit 14 abgerundet sind. In der Nähe der Ecken weist die Trägerplatte 22 vier Durchgangsbohrungen 28 auf, durch welche jeweils eine Schraube zur Befestigung der Gegeneinheit hindurchgeführt werden kann.The carrier plate 22 has a rectangular shape, the four corners of which are rounded for better handling of the counter unit 14. In the vicinity of the corners, the carrier plate 22 has four through bores 28, through which a screw for fastening the counter-unit can be passed.

In Fig. 1 ist die Gegeneinheit 14 mit ihrer bezogen auf eine Betriebsorientierung äußeren Seite gezeigt. Der Begriff "Betriebsorientierung" beschreibt eine Anordnung der Gegeneinheit in einem Zustand, in dem sie, wie in Fig. 6 gezeigt, an einer Gehäusewand 18 eines Gehäuses 10 befestigt ist. Mit anderen Worten bezieht sich der Begriff "Betriebsorientierung" auf die Orientierung der Gegeneinheit 14 relativ zu dem Gehäuse 10 während des Betriebs der Vakuumpumpe. Die in Fig. 1 nicht gezeigte innere Seite der Trägerplatte 22 ist somit in der Betriebsorientierung dem Inneren des Gehäuses 10 zugewandt, während die dargestellte äußere Seite der Trägerplatte 22 von dem Gehäuse 10 abgewandt ist, wie es in Fig. 6 gezeigt ist.In Fig. 1 the counter unit 14 is shown with its outer side in relation to an operational orientation. The term "operational orientation" describes an arrangement of the counter unit in a state in which, as in Fig. 6 shown, is attached to a housing wall 18 of a housing 10. In other words, the term “operating orientation” refers to the orientation of the counter unit 14 relative to the housing 10 during the operation of the vacuum pump. In the Fig. 1 In the operational orientation, the inner side of the carrier plate 22, not shown, thus faces the interior of the housing 10, while the illustrated outer side of the carrier plate 22 faces away from the housing 10, as shown in FIG Fig. 6 is shown.

Fig. 2 zeigt die Gegeneinheit 14 in einer Seitenansicht. Der Anschlussverbinder 24 ist auf der äußeren - hier oberen - Seite der Trägerplatte 22 befestigt. An der inneren - hier unteren - Seite der Trägerplatte 22 entspringen die Leitungen 16, die zu der hier nicht dargestellten Funktionseinheit 12 führen. Der Anschlussverbinder 24 ist durch die Trägerplatte 22 hindurch mit den Leitungen 16 elektrisch verbunden. Fig. 2 shows the counter unit 14 in a side view. The connection connector 24 is fastened on the outer — here upper — side of the carrier plate 22. The lines 16, which lead to the functional unit 12, not shown here, arise on the inner — in this case lower — side of the carrier plate 22. The connection connector 24 is electrically connected to the lines 16 through the carrier plate 22.

In Fig. 3 ist die innere Seite der Trägerplatte 22 der Gegeneinheit 14 dargestellt. Die Leitungen 16 sind jeweils mit der Trägerplatte 22 und mit Pins der Buchse des hier verdeckten Anschlussverbinders 24 verlötet, so dass die Leitungen 16 und der Anschlussverbinder 24 elektrisch miteinander verbunden sind und an der Trägerplatte 22 dauerhaft befestigt sind.In Fig. 3 the inner side of the carrier plate 22 of the counter unit 14 is shown. The lines 16 are each soldered to the carrier plate 22 and to the pins of the socket of the connector 24 hidden here, so that the lines 16 and the connector 24 are electrically connected to one another and are permanently attached to the carrier plate 22.

Fig. 4 zeigt einen Abschnitt eines Gehäuses 10 einer Vakuumpumpe. Das Gehäuse 10 umfasst eine Gehäusewand 18, in welcher eine rechteckige Öffnung 20 ausgebildet ist. Die Öffnung wird von einer Dichtung 26 umrahmt. Passend zu den Durchgangsbohrungen 28 der Trägerplatte 22 weist die Gehäusewand 18 vier Gewindebohrungen 30 auf, in denen Schrauben zur Befestigung der Gegeneinheit 14 an der Gehäusewand 18 eingeschraubt werden können. Fig. 4 shows a section of a housing 10 of a vacuum pump. The housing 10 comprises a housing wall 18 in which a rectangular opening 20 is formed. The opening is framed by a seal 26. Matching the through bores 28 of the carrier plate 22, the housing wall 18 has four threaded bores 30, into which screws for fastening the counter unit 14 to the housing wall 18 can be screwed.

In Fig. 5 ist die Gegeneinheit 14 gezeigt, wie sie in einer Montageorientierung durch die Öffnung 20 der Gehäusewand 18 des Gehäuses 10 hindurchgeführt wird. Die Gegeneinheit 14 wird dabei seitlich entlang ihrer Längsachse senkrecht zur Erstreckungsebene der Öffnung 22 durch die Öffnung 22 hindurchgeführt, insbesondere hindurchgeschoben.In Fig. 5 the counter unit 14 is shown as it is guided through the opening 20 of the housing wall 18 of the housing 10 in an assembly orientation. The counter unit 14 is guided laterally along its longitudinal axis perpendicular to the plane of extent of the opening 22 through the opening 22, in particular pushed through.

Nachdem die Gegeneinheit 14 vollständig durch die Öffnung 20 hindurchgeführt wurde, wird die Gegeneinheit 14, wie in Fig. 6 dargestellt, in ihrer Betriebsorientierung mit Schrauben 32 an die Gehäusewand geschraubt. Dabei verdeckt die innere Seite der Trägerplatte 22 die Öffnung 20 und die Dichtung 26 wird mit der inneren Seite der Trägerplatte 22 in Eingriff gebracht, so dass die Dichtung 26 das Innere des Gehäuses 10 wirksam abdichtet.After the counter-unit 14 has been completely passed through the opening 20, the counter-unit 14, as in FIG Fig. 6 shown, screwed in their operational orientation with screws 32 to the housing wall. The inner side of the carrier plate 22 covers the opening 20 and the seal 26 is brought into engagement with the inner side of the carrier plate 22, so that the seal 26 effectively seals the interior of the housing 10.

In den Fig. 6 und 7 sind Größenverhältnisse von Gegeneinheit 14 und Öffnung 20 dargestellt, die es ermöglichen, dass die Gegeneinheit 14 in der Montageorientierung durch die Öffnung 20 hindurchführbar ist, die Öffnung 20 aber in der Betriebsorientierung abdeckt. Dazu ist in Fig. 7 die Öffnung 20 der Fig. 5 vergrößert dargestellt.In the Fig. 6 and 7 The proportions of the counter unit 14 and the opening 20 are shown, which make it possible for the counter unit 14 to be passed through the opening 20 in the assembly orientation, but to cover the opening 20 in the operating orientation. This is in Fig. 7 the opening 20 of the Fig. 5 shown enlarged.

Die Gegeneinheit 14 weist eine Länge l auf, die durch den Abstand der zwei kurzen Seiten der Rechteckform der Trägerplatte 22 definiert ist. Wie aus Fig. 7 ersichtlich, weist die Gegeneinheit 14 eine Maximalbreite a auf, die durch den Abstand der beiden langen Seiten der Rechteckform der Trägerplatte 22 definiert ist. Eine Maximalhöhe b der Gegeneinheit 14 ist durch die gesamte Ausdehnung der Gegeneinheit 14 in vertikaler Richtung, das heißt einschließlich des Anschlussverbinders 24, der Trägerplatte 22 und der Leitung 16, definiert. Eine Breite c der Öffnung 20 beschreibt eine Breite der rechteckigen Öffnung in horizontaler Richtung oder mit anderen Worten den Abstand der kurzen Seiten der Rechteckform der Öffnung 20. Der Abstand der langen Seiten der Rechteckform der Öffnung 20 definiert eine Höhe d der Öffnung 20.The counter unit 14 has a length l, which is defined by the distance between the two short sides of the rectangular shape of the carrier plate 22. How out Fig. 7 can be seen, the counter unit 14 has a maximum width a, which is defined by the distance between the two long sides of the rectangular shape of the carrier plate 22. A maximum height b of the counter unit 14 is defined by the entire extent of the counter unit 14 in the vertical direction, that is to say including the connection connector 24, the carrier plate 22 and the line 16. A width c of the opening 20 describes a width of the rectangular opening in the horizontal direction or in other words the distance between the short sides of the rectangular shape of the opening 20. The distance of the long sides of the rectangular shape of the opening 20 defines a height d of the opening 20.

Die Maximalbreite a der Gegeneinheit 14 ist kleiner als die Breite c der Öffnung 20 und die Maximalhöhe b der Gegeneinheit 14 ist kleiner als die Höhe d der Öffnung 20. Die Maximalbreite a der Gegeneinheit 14 ist aber größer als die Höhe d der Öffnung 20 und die Länge l der Gegeneinheit 14 ist größer als die Breite c der Öffnung 20. Wie in Fig. 6 dargestellt deckt daher die Gegeneinheit 14 die Öffnung 20 vollständig ab.The maximum width a of the counter unit 14 is smaller than the width c of the opening 20 and the maximum height b of the counter unit 14 is smaller than the height d of the opening 20. However, the maximum width a of the counter unit 14 is larger than the height d of the opening 20 and Length l of counter unit 14 is greater than width c of opening 20. As in Fig. 6 shown, the counter unit 14 therefore completely covers the opening 20.

In der gezeigten Ausführungsform wird die Gegeneinheit 14 derart durch die Öffnung 20 hindurchgeführt, dass die Trägerplatte 22 mit ihrer Erstreckungsebene im Wesentlichen parallel zu den langen Seiten der Rechteckform der Öffnung 20 ausgerichtet ist. Es sind nicht nur andere Formen für die Gegeneinheit 14 und die Öffnung 20, wie zum Beispiel elliptische, parallelogrammartige oder unregelmäßige Formen, denkbar. Auch kann die Gegeneinheit 14 in einer anderen als der parallelen Montageorientierung durch die Öffnung 20 hindurchgeführt werden. Die Gegeneinheit 14 kann also zum Beispiel diagonal und/oder schräg durch eine Rechteckform der Öffnung 20 hindurchgeführt werden.In the embodiment shown, the counter unit 14 is guided through the opening 20 such that the support plate 22 is oriented with its plane of extension essentially parallel to the long sides of the rectangular shape of the opening 20. Not only other shapes for the counter unit 14 and the opening 20 are conceivable, such as elliptical, parallelogram-like or irregular shapes. The counter unit 14 can also be guided through the opening 20 in a different orientation than the parallel assembly. The counter unit 14 can thus be passed diagonally and / or obliquely through a rectangular shape of the opening 20, for example.
