- the motor is first placed in the housing. Subsequently, a lead is led out from the motor through an opening of the housing and the lead is electrically connected to a terminal unit for the control unit outside the housing, e.g. soldered. The connection unit is then fastened to the outside of the housing.

- the counter unit may comprise a plate-shaped element, which is greater in width and length than other components of the counter unit, if such other components are present.
- the maximum height in this case is defined by a thickness of the plate-shaped member together with an extension of the other components in the direction of expansion of the thickness.
- the plate-shaped element is at least substantially rectangular.
- the preparation of the counter unit is simplified.
- the plate-shaped element may be a carrier plate which carries one or more further components of the counter unit.

- a functional unit 12 and a counter unit 14 are shown, which are connected via three lines 16.
- the functional unit 12 may comprise, for example, a motor of the vacuum pump.
- the counter unit 14 comprises a printed circuit board 22 designed as a printed circuit board, which carries a connection connector 24.
- the terminal connector 24 is designed as a socket for a plug of another 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 connector 24 and, for example, each associated with a phase of an electric drive of the motor.
- the support plate 22 has a rectangular shape, the four corners are rounded for better handling of the counter unit 14. In the vicinity of the corners, the support plate 22 has four through holes 28, through which in each case a screw for fastening the counter unit can be passed.
- Fig. 1 the counter unit 14 is shown with its outer side relative to an operational orientation.
- the term "operational orientation” describes an arrangement of the counterpart unit in a state in which they, as in Fig. 6 shown attached to a housing wall 18 of a housing 10.
- the term “operational orientation” refers to the orientation of the counter unit 14 relative to the housing 10 during operation of the vacuum pump.
- inner side of the support plate 22 is thus in the operating orientation facing the interior of the housing 10, while the illustrated outer side of the support plate 22 facing away from the housing 10, as shown in FIG Fig. 6 is shown.
- Fig. 2 shows the counter unit 14 in a side view.
- the connection connector 24 is mounted on the outer - here upper - side of the support plate 22.
- the terminal connector 24 is electrically connected to the leads 16 through the support plate 22.
- Fig. 3 the inner side of the support plate 22 of the counter unit 14 is shown.
- the leads 16 are each soldered to the support plate 22 and to pins of the socket of the connector 24 concealed here so that the leads 16 and the lead connector 24 are electrically connected together and permanently secured to the support plate 22.
- Fig. 4 shows a portion 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.
- the housing wall 18 has four threaded holes 30 in which screws for fastening the counter unit 14 can be screwed to the housing wall 18.
- Fig. 5 the counter unit 14 is shown as being guided through the opening 20 of the housing wall 18 of the housing 10 in a mounting orientation.
- the counter unit 14 is guided laterally along its longitudinal axis perpendicular to the plane of extension of the opening 22 through the opening 22, in particular pushed through.
- the counter unit 14 After the counter unit 14 has been completely passed through the opening 20, the counter unit 14, as in Fig. 6 shown screwed in their operational orientation with screws 32 to the housing wall. At this time, the inner side of the support plate 22 hides the opening 20, and the seal 26 is engaged with the inner side of the support plate 22, so that the seal 26 effectively seals the interior of the housing 10.
- the counter unit 14 has a length I, which is defined by the distance between the two short sides of the rectangular shape of the support 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 support plate 22.

- a width c of the opening 20 describes a width of the rectangular opening in the horizontal direction, or in other words the distance of 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 20th
- 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 greater than the height d of the opening 20 and Length I of the counter unit 14 is greater than the width c of the opening 20. As in Fig. 6 therefore, the counter unit 14 completely covers the opening 20.
- the counter unit 14 is passed through the opening 20 such that the support plate 22 is aligned with its extension plane substantially parallel to the long sides of the rectangular shape of the opening 20.
- the counter unit 14 and the opening 20 can be passed through the opening 20 in a direction other than the parallel mounting orientation.
- the counter unit 14 can thus be passed, for example, diagonally and / or obliquely through a rectangular shape of the opening 20.

Description
Die vorliegende Erfindung betrifft eine Vakuumpumpe und ein Verfahren zur Herstellung einer Vakuumpumpe.The present invention relates to a vacuum pump and a method of manufacturing a vacuum pump.
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 includes a motor disposed inside a housing of the vacuum pump and a motor control unit disposed outside the housing. In this case, the housing must be sealed to an external area to maintain a vacuum in the housing, while at the same time an electrical connection between the engine 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 of manufacturing such a vacuum pump, the motor is first placed in the housing. Subsequently, a lead is led out from the motor through an opening of the housing and the lead is electrically connected to a terminal unit for the control unit outside the housing, e.g. soldered. The connection unit is then fastened to the outside of the housing.
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 connection to the connection unit. The engine can therefore only be tested after it is 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 having the features of
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 electrically and / or information technology connected before the assembly of the functional unit in the housing of the vacuum pump. The functional unit and the counter unit can thus be first tested independent of the remaining components much earlier in the manufacturing process of the vacuum pump. As a result, possible errors can be eliminated with less effort. Second, the assembly itself is simplified and accelerated because e.g. a thermal joining of the line to the counter unit during the assembly process can be omitted.
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 carried out in a suitably encapsulated or potted manner during the production, since the connection no longer needs to be released later during the assembly of the vacuum pump. This has, inter alia, the advantage that the connection can be safely and reliably protected from external influences and thus 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 therefore be jointly provided as a finished component of the vacuum pump, which opens up the possibility to obtain this component as a whole from a specialized manufacturer who can make a final test of the functional unit itself. In addition, the dismantling and repair of the vacuum pump is simplified by the invention, since an optionally existing seal, for example in the form of a O-ring 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 inventively achieved in particular when the line is not connected to the counter unit via a 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 may comprise a motor for the vacuum pump. Alternatively or additionally, the functional unit may 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 may comprise means for transmitting power and / or information, the means being 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 has at least substantially a rectangular shape. The term shape refers to a basic form which in further embodiments of the invention e.g. may deviate from an ideal shape, such as a rectangular shape, due to curves or bevels or additional recesses.
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 mounting orientation on a maximum width, a maximum height and a perpendicular to the plane of the opening extending length. 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 greater than a height of the opening, and the length of the counter unit is greater 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.Even with this embodiment, which is based on a relatively simple geometry, a complete covering of the opening by the counter unit can be ensured. The terms "height", "width" and "length" refer only to the dimensions of aperture and counter unit in different directions. In particular, the term "height" is not limited to a vertical extension direction but may be e.g. also describe an expansion in the horizontal direction, in which case the term "width" can describe an extension in the vertical direction. However, "height", "width" and "length" may also apply to any other, e.g. oblique, extend 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 mounting 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 may comprise a plate-shaped element, which is greater in width and length than other components of the counter unit, if such other components are present. The maximum height in this case is defined by a thickness of the plate-shaped member together with an extension of the other 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. The preparation of the counter unit is simplified.
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 may be a carrier plate which carries one or more further components of the counter unit. The further components may include, for example, relatively simple components, such as one or more connection elements, or even more complex devices, such as a control unit for the functional unit. The components may be permanently or detachably 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 printed circuit board or circuit board can be designed for further line functions and / or further components, such as e.g. Computing or control units, include 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 made relatively small, because additional necessary components can be "outsourced" to some extent in the further functional unit. Thus, only a small opening in the housing wall is necessary through which only a relatively small counter unit must be passed. The often tight space in a vacuum pump can thus be better utilized. The further functional unit may e.g. a control unit and / or a power supply for the functional unit, e.g. for a motor, in which enclosing 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 terminal connector may be disposed on an outer side of the counter unit in the operational orientation and connected to the lead on the inner side of the counter unit. In particular, a connection connector can be combined with a circuit board of the counter unit, wherein the connection connector can have at least one pin which is passed through the circuit board and soldered to the line on the inner side of the circuit board. Alternatively or additionally, the connection connector may be mounted on the outside surface of the circuit board and connected by printed conductors to the inner side of the circuit board 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. Thus, a simple, releasable connection of the counter unit is ensured with the housing wall.
Zwischen der Gegeneinheit und der Gehäusewand kann eine Dichtung vorgesehen sein.Between the counter unit and the housing wall, a seal may be provided.
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. In this recess, the seal, for example an O-ring, can be securely fixed and e.g. compressed defined by screwing the counter unit to the housing wall 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 line can be flexible. The counter unit can be particularly easy to pass through the opening. In particular, the line comprises one or more cables, each of which may 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 may for example be soldered and / or potted with the counter unit. This improves the stability of the connection and the 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 of manufacturing 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 given in the dependent claims, the description and the figures.
