Description

Die Erfindung bezieht sich auf einen Deckel für eine Kammer eines Gehäuses eines Gerätes, mit einem etwa plattenartigen Träger, der ein als Stanzgitter ausgebildetes Leiterbahnmuster trägt, mit einem an dem Leiterbahnmuster angeordneten Sensor und einer an dem Träger ausgebildeten Steckeraufnahme für einen Gerätestecker zur Kontaktierung des Leiterbahnmusters.The invention relates to a cover for a chamber of a housing of a device, comprising an approximately plate-like support carrying a printed circuit pattern designed as a punched grid, arranged on the conductor pattern and a sensor formed on the carrier connector receptacle for a device connector for contacting the conductor pattern ,

Bei einem derartigen Deckel (siehe z.B. US 6 407 543 B1) ist es bekannt das Stanzgitter bei der Herstellung des Trägers im Kunststoff-Spritzgußverfahren mit einzuspritzen und anschließend die nicht zum Leiterbahnmuster gehörenden Verbindungsstellen des Stanzgitters zu trennen.In such a lid (see, for example, US Pat. No. 6,407,543 B1), it is known to inject the stamped grid during the production of the carrier by the plastic injection molding method and then to separate the connecting points of the stamped grid which do not belong to the printed conductor pattern.

Aufgrund der hohen Spritzdrücke, die dabei auf das Stanzgitter einwirken, muß die Konfiguration des Stanzgitters hinsichtlich der Leiterbahnverläufe, der Leiterbahnabstände und der Verbindungsstellen so ausgebildet werden, daß es nicht zu Deformationen der Leiterbahnen und dabei zu Lageverschiebungen der Sensorposition und des Steckerkontakts kommen kann. Diese hohe Anforderungen erfordern einen großen Aufwand und führen zu Einschränkungen der Leiterbahnverläufe.Due to the high injection pressures, which act on the stamped grid, the configuration of the stamped grid must be so formed with respect to the conductor tracks, the conductor track distances and the connection points that it can not lead to deformation of the conductor tracks and thereby position shifts the sensor position and the plug contact. These high demands require a great deal of effort and lead to restrictions on the tracks.

Aufgabe der Erfindung ist es daher einen Deckel der eingangs genannten Art zu schaffen, der aus einfachen Bauteilen besteht, leicht montierbar ist und eine einwandfreie Funktion sicher stellt.The object of the invention is therefore to provide a cover of the type mentioned above, which consists of simple components, is easy to assemble and ensures proper operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Stanzgitter auf dem etwa plattenartigen Träger in Auflage, durch Fixierelemente gehalten und von einer mit dem Träger an ihrem umlaufenden Rand verbundenen Abdeckung überdeckt ist.This object is achieved in that the stamped grid on the approximately plate-like support in support, held by fixing elements and is covered by a connected to the carrier at its peripheral edge cover.

Durch diese Ausbildung wird das separat hergestellte Stanzgitter auf den ebenfalls separat hergestellten Träger aufgebracht und von den Fixierelementen in seiner Einbaulage gehalten. Danach werden die Verbindungsstellen getrennt und die Abdeckung aufgebracht.As a result of this design, the stamped grid produced separately is applied to the likewise separately produced carrier and held by the fixing elements in its installed position. Thereafter, the joints are separated and applied the cover.

Da keine Kraftbeaufschlagungen durch hohe Spritzdrücke vorhanden sind, reichen wenige Verbindungsstellen aus. Die Fixierelemente führen zu einer exakten Positionierung der Leiterbahnen und damit auch des Sensors und der Steckkontakte, so daß auch nur geringe Abstände zwischen den Leiterbahnen des Leiterbahnmusters nötig sind. Damit kann auch die Baugröße des Deckels gering gehalten werden.Since there are no force loads due to high injection pressures, few connection points are sufficient. The fixing elements lead to an exact positioning of the conductor tracks and thus also of the sensor and the plug contacts, so that only small distances between the tracks of the conductor pattern are necessary. Thus, the size of the lid can be kept low.

Der Sensor kann problemlos vor der Montage des Stanzgitters aufgebracht werden. Dies ermöglicht es das Stanzgitter mit dem Sensor an einem anderen Standort zu fertigen als dem Standort der Herstellung von Träger und Abdeckung, so daß rationeller, flexibler und kostengünstiger gefertigt werden kann.The sensor can be easily applied before mounting the stamped grid. This makes it possible to produce the stamped grid with the sensor at a different location than the location of the production of the carrier and cover, so that more rational, flexible and cost-effective can be made.

Varianten der Deckel mit anderen Maßen und anderen Steckern für unterschiedliche Geräte sind leicht möglich, wobei die Grundmaße für den Träger beibehalten werden können.Variants of the lids with other dimensions and other plugs for different devices are easily possible, the basic dimensions for the carrier can be maintained.

Das Stanzgitter kann Kontaktzungen zur Kontaktierung mit dem Gerätestecker aufweisen, die in die Steckeraufnahme hineinragen.The stamped grid may have contact tongues for contacting with the device plug, which protrude into the connector receptacle.

Dabei können bauteilreduzierend die Kontaktzungen insbesondere aus der Ebene des Stanzgitters abgebogene Teile des Stanzgitters sein.In this case, the contact tongues, in particular from the plane of the stamped grid, can be component parts of the stamped grid that are bent away from the component.

Zur richtigen Positionierung des Gerätesteckers zu den Kontaktzungen kann die Steckeraufnahme hülsenartig von dem Träger hervorstehend ausgebildet sein, wobei vorzugsweise die Steckeraufnahme einteilig mit dem Stecker ausgebildet ist.For correct positioning of the appliance plug to the contact tongues, the plug receptacle may be formed like a sleeve protruding from the carrier, wherein preferably the plug receptacle is integrally formed with the plug.

Für weitere Kontaktierungen kann die Trägerplatte eine oder mehrere Durchführungen aufweisen, durch die eine oder mehrere weitere Kontaktzungen auf der dem Stanzgitter abgewandten Seite der Trägerplatte hervorragend hindurchgeführt sind.For further contacting, the carrier plate can have one or more feedthroughs, through which one or more further contact tongues are passed outstandingly on the side of the carrier plate facing away from the stamped grid.

Dabei sind zur Bauteilreduzierung auch die eine oder mehreren weiteren Kontaktzungen insbesondere aus der Ebene des Stanzgitters abgebogene Teile des Stanzgitters.In this case, to reduce the component and the one or more other contact tongues in particular from the plane of the punched grid bent parts of the stamped grid.

Zum Schutz des Sensors gegen Verschmutzung und mechanische Beschädigung kann der Träger auf seiner dem Stanzgitter abgewandeten Seite ein Sensorgehäuse aufweisen, in das der Sensor hineinragt, wobei vorzugsweise Träger und Sensorgehäuse einteilig ausgebildet sind.To protect the sensor against contamination and mechanical damage, the carrier may have on its side facing away from the stamped grid a sensor housing into which the sensor protrudes, preferably carrier and sensor housing are integrally formed.

Die weiteren Kontaktzungen und/oder der Sensor oder das Sensorgehäuse können in die Kammer des Gehäuses ragen.The further contact tongues and / or the sensor or the sensor housing can protrude into the chamber of the housing.

Zum Schutz gegen Umwelteinflüsse ist in bauteilsparender Weise die Abdeckung an ihrem umlaufenden Rand mit dem Träger verschweißt, insbesondere laserverschweißt, oder verklebt.To protect against environmental influences the cover is welded at its peripheral edge to the carrier in a component-saving manner, in particular laser welded, or glued.

Es ist aber auch möglich, daß die Abdeckung mit ihrem umlaufenden Rand über eine umlaufende Dichtung auf dem Träger in Auflage und durch insbesondere eine Schraubverbindung mit dem Träger lösbar verbunden ist.But it is also possible that the cover with its peripheral edge via a peripheral seal on the support in support and in particular a screw connection to the carrier is releasably connected.

Eine einfache, schnelle und positionsgenaue Montage ist dadurch möglich, daß die Fixierelemente Rastelemente oder Klemmelemente sind, in die das Stanzgitter einrastbar oder einklemmbar ist.A simple, fast and accurate position mounting is possible in that the fixing elements are latching elements or clamping elements into which the stamped grid can be latched or clamped.

Sind dabei die Rastelemente oder Klemmelemente einteilig mit dem Träger ausgebildet, führt dies zu einer Reduzierung des Montageaufwandes und zu wenigen erforderlichen Bauteilen.If the latching elements or clamping elements are formed integrally with the carrier, this leads to a reduction of the assembly effort and to a few required components.

Einfach herstellbar und gleichzeitig die Leiterbahnen voneinander isolierend kann der Träger ein Kunststoffteil, insbesondere ein Kunststoff-Spritzgußteil sein.Easy to manufacture and at the same time insulating the interconnects from one another, the carrier can be a plastic part, in particular a plastic injection-molded part.

Diese einfache Herstellbarkeit ist auch gegeben, wenn die Abdeckung ein schalen- oder topfförmiges Kunststoffteil, insbesondere Kunststoff-Spritzgußteil ist.This ease of manufacture is also given if the cover is a cup-shaped or pot-shaped plastic part, in particular plastic injection-molded part.

Das Stanzgitter kann auf unterschiedliche Weise aufgebaut sein. So kann das Stanzgitter aus einem Blech (leat frame) oder aus einer Leiterbahnen tragenden Leiterplatte ausgestanzt sein.The stamped grid can be constructed in different ways. Thus, the stamped grid can be punched out of a sheet (leat frame) or of a printed circuit board carrying printed conductors.

Zur einfachen Montage kann der Träger die Kammer des Gehäuses verschließend mittels Schrauben mit dem Gehäuse verbindbar sein.For ease of installation, the carrier can be the housing of the housing closing by means of screws connected to the housing.

Der Deckel ist für die verschiedensten Geräte verwendbar. So kann er z.B. an Fahrpedalmodulen verwendet werden. Eine vorzugsweise Verwendung besteht darin, daß das Gerät ein Drosselklappenstutzen für einen Verbrennungsmotor insbesondere eines Kraftfahrzeugs ist und in dem Gehäuse eine durchgehende Drosselöffnung ausgebildet ist, die von einer auf einer Drosselklappenwelle angeordneten Drosselklappe absperrbar ist, wobei in dem Gehäuse ein elektromotorischer Antrieb angeordnet ist, durch den insbesondere über ein Getriebe die Drosselklappenwelle schwenkbar antreibbar ist.The lid can be used for a wide variety of devices. So he can e.g. be used on accelerator pedal modules. A preferred use is that the device is a throttle body for an internal combustion engine, in particular of a motor vehicle and in the housing a continuous throttle opening is formed, which is shut off by a arranged on a throttle shaft throttle, wherein in the housing an electric motor drive is arranged through in particular via a gearbox, the throttle shaft is pivotally driven.

Dabei kann der Sensor ein die Stellung der Drosselklappenwelle oder des Getriebes erfassender Stellungssensor sein.In this case, the sensor may be a position sensor detecting the position of the throttle shaft or of the transmission.

Eine kontaktlose Stellungserfassung des Getriebes ist dabei auf einfache Weise möglich, wenn der Sensor ein magnetoresistiver Sensor oder ein Hall-Sensor ist.A contactless position detection of the transmission is possible in a simple manner, if the sensor is a magnetoresistive sensor or a Hall sensor.

Die zumindest eine oder weiteren Kontaktzungen können ein Motorstecker zur Kontaktierung des elektromotorischen Antriebs sein.The at least one or more contact tongues may be a motor plug for contacting the electromotive drive.

Der in den Figuren dargestellte Drosselklappenstutzen besitzt ein Gehäuse 2, in dem eine Drosselöffnung 3 ausgebildet ist. Quer durch die Drosselöffnung 3 ist eine Drosselklappenwelle 4 geführt, die eine Drosselklappe 5 trägt, durch die der Durchtrittsquerschnitt der Drosselöffnung 3 absperrbar ist.The throttle body shown in the figures has a housing 2, in which a throttle opening 3 is formed. Through the throttle opening 3, a throttle valve shaft 4 is guided, which carries a throttle valve 5, through which the passage cross-section of the throttle opening 3 can be shut off.

Die beiden Enden der Drosselklappenwelle 4 sind in Lagerbohrungen des Gehäuses 2 drehbar gelagert. Das eine freie Ende der Drosselklappenwelle 4 ragt durch einen Boden in eine topfartige Gehäusekammer des Gehäuses 2, deren nach außen gerichtete Öffnung durch einen Gehäusedeckel 8 verschließbar ist.The two ends of the throttle shaft 4 are rotatably mounted in bearing bores of the housing 2. The one free end of the throttle shaft 4 protrudes through a bottom into a pot-like housing chamber of the housing 2, whose outwardly directed opening can be closed by a housing cover 8.

In einer Motorkammer, die mit ihrem einen Ende in die Gehäusekammer mündet, ist ein Elektromotor angeordnet, auf dessen Motorwelle ein Antriebsritzel sitzt. Das Antriebsritzel treibt über ein Getriebe die Drosselklappenwelle 4 drehbar an.In an engine chamber, which opens with its one end into the housing chamber, an electric motor is arranged, on the motor shaft, a drive pinion sits. The drive pinion rotatably drives the throttle shaft 4 via a transmission.

Der Gehäusedeckel 8 weist einen plattenartigen Träger 9 auf, der ein isolierendes Kunststoff-Spritzgußteil ist, eine hülsenartige Steckeraufnahme 10 zur Kontaktierung mit einem Gerätestecker, ein topfartiges Sensorgehäuse 11 sowie eine weitere Steckeraufnahme 12 eines Motorsteckers, die alle in die topfartige Gehäusekammer ragen.The housing cover 8 has a plate-like support 9, which is an insulating plastic injection molded part, a sleeve-like connector receptacle 10 for contacting with a device connector, a pot-like sensor housing 11 and a further connector receptacle 12 of a motor connector, all of which protrude into the pot-like housing chamber.

Auf die der Gehäusekammer abgewandte Seite des Trägers 9 ist ein Stanzgitter 6 aufgelegt und die Leiterbahnen 7 des Stanzgitters 6 sind durch nicht dargestellte Rastelemente in ihrer Position gehalten. Nach dieser rastenden Befestigung der Leiterbahnen 7 auf dem Träger 9 werden die Verbindungsstellen 13 der Leiterbahnen 7 des Stanzgitters 6 aufgetrennt.On the side facing away from the housing chamber of the support 9, a stamped grid 6 is placed and the conductor tracks 7 of the stamped grid 6 are held by not shown locking elements in position. After this latching attachment of the conductor tracks 7 on the carrier 9, the connection points 13 of the conductor tracks 7 of the stamped grid 6 are separated.

Endbereiche der Leiterbahnen 7 sind rechtwinklig aus der Ebene des Stanzgitters 6 abgebogen und bilden Kontaktzungen 14, die durch entsprechende Durchführungen im Träger 9 hindurch in die Steckeraufnahme 10 ragen.End regions of the conductor tracks 7 are bent at right angles out of the plane of the stamped grid 6 and form contact tongues 14 which protrude through corresponding passages in the carrier 9 into the plug receptacle 10.

Eine weitere abgebogene Kontaktzunge 15 durchragt ebenfalls den Träger 9 und ragt in die Steckeraufnahme 12 hinein, die einen Motorstecker zur Kontaktierung des Elektromotors bildet.Another bent contact tongue 15 also protrudes through the carrier 9 and protrudes into the plug receptacle 12, which forms a motor plug for contacting the electric motor.

Weitere Leiterbahnen 7 sind abgebogen und tragen einen magneto-resistiven Sensor 16. Dieser Sensor 16 ragt durch eine entsprechende Öffnung in das Sensorgehäuse 11 hinein und dient als Stellungssensor zur Erfassung der Stellung des Getriebes und damit der Drosselklappe 5.Further strip conductors 7 are bent and carry a magneto-resistive sensor 16. This sensor 16 protrudes through a corresponding opening in the sensor housing 11 and serves as a position sensor for detecting the position of the transmission and thus the throttle valve. 5

Die Leiterbahnen 7 des Stanzgitters 6 sind vollständig von einer schalenartigen Abdeckung 17 bedeckt, die an ihrem umlaufenden Rand mit dem Träger 9 laserverschweißt und damit der Raum der Leiterbahnen 7 dicht abgeschlossen ist.The conductor tracks 7 of the stamped grid 6 are completely covered by a shell-like cover 17 which is laser-welded at its peripheral edge to the carrier 9 and thus the space of the conductor tracks 7 is sealed.

Der Träger 9 und damit der gesamte Gehäusedeckel 8 ist mittels Schrauben 18 mit dem Gehäuse 2 verbunden und verschließt dessen Gehäusekammer nach außen.The carrier 9 and thus the entire housing cover 8 is connected by means of screws 18 to the housing 2 and closes the housing chamber to the outside.
