Description

Beschreibungdescription
Deckelcover
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, with an approximately plate-like carrier which carries a printed conductor pattern designed as a lead frame, with a sensor arranged on the printed conductor pattern and a plug receptacle formed on the carrier for a device plug for contacting the printed conductor pattern ,
Bei einem derartigen Deckel 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.With such a cover, it is known to inject the lead frame during the manufacture of the carrier in a plastic injection molding process and then to separate the connection points of the lead frame which do not belong to the 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 spray pressures that act on the lead frame, the configuration of the lead frame with regard to the conductor path, the conductor spacing and the connection points must be designed so that there can be no deformation of the conductor paths and thereby shifting the position of the sensor position and the connector contact. These high requirements require a great deal of effort and lead to restrictions on the conductor path.
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 lid of the type mentioned, which consists of simple components, is easy to assemble and ensures proper functioning.
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. 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 .This object is achieved in that the lead frame is held on the approximately plate-like support, held by fixing elements and covered by a cover connected to the support at its peripheral edge. As a result of this design, the separately produced lead frame is applied to the carrier, which is also produced separately, and is held in its installed position by the fixing elements. The connection points are then separated and the cover is applied.
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 derSince there are no forces exerted by high spray pressures, a few connection points are sufficient. The fixing elements lead to an exact positioning of the conductor tracks and thus also the sensor and the
Steckkontakte, so daß auch nur geringe Abstände zwischen den Leiterbahnen des Leiterbahnmusters nötig sind. Damit kann auch die Baugröße des Deckels gering gehalten werden.Plug contacts, so that only small distances between the conductor tracks of the conductor pattern are necessary. This also allows the size of the cover to be kept small.
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 easily be applied before the lead frame is installed. This makes it possible to manufacture the lead frame with the sensor at a different location than the location where the carrier and cover are produced, so that production can be carried out more efficiently, flexibly and cost-effectively.
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 lid with different dimensions and different plugs for different devices are easily possible, while the basic dimensions for the carrier can be retained.
Das Stanzgitter kann Kontaktzungen zur Kontaktierung mit dem Gerätestecker aufweisen, die in die Steckeraufnahme hineinragen.The lead frame can have contact tongues for contacting the device connector, 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 can be component-reducing, in particular parts of the lead frame bent out of the plane of the lead frame.
Zur richtigen Positionierung des Gerätesteckers zu den Kontaktzungen kann die Steckeraufnahme hülsenartig von demFor correct positioning of the device connector to the contact tongues, the connector receptacle can be sleeve-like
Träger hervorstehend ausgebildet sein, wobei vorzugsweise die Steckeraufnahme einteilig mit dem Stecker ausgebildet ist. 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.Carrier be formed protruding, wherein the connector receptacle is preferably formed in one piece with the connector. For further contacts, the carrier plate can have one or more bushings through which one or more further contact tongues on the side of the carrier plate facing away from the lead frame are excellently guided.
Dabei sind zur Bauteilreduzierung auch die eine oder mehreren weiteren Kontaktzungen insbesondere aus der Ebene des Stanzgitters abgebogene Teile des Stanzgitters.In order to reduce the number of components, the one or more further contact tongues, in particular parts of the leadframe which are bent out of the plane of the leadframe, are also.
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 dirt and mechanical damage, the carrier can have a sensor housing on its side facing away from the lead frame, into which the sensor protrudes, the carrier and sensor housing preferably being formed in one piece.
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 to the carrier at its peripheral edge, in particular laser-welded, or glued in a component-saving manner.
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 .However, it is also possible for the cover to be detachably connected to the support with its peripheral edge by means of a peripheral seal on the support and, in particular, by a screw connection.
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, quick and positionally accurate assembly is possible in that the fixing elements are latching elements or clamping elements into which the lead frame can be snapped 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. Einfach herstellbar und gleichzeitig die Leiterbahnen voneinander isolierend kann der Träger ein Kunststoffteil, insbesondere ein Kunststoff-Spritzgußteil sein.If the latching elements or clamping elements are formed in one piece with the carrier, this leads to a reduction in the assembly effort and to a few required components. The carrier can be a plastic part, in particular a plastic injection-molded part, that is easy to manufacture and at the same time isolates the conductor tracks from one another.
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 shell-shaped or cup-shaped plastic part, in particular a 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 lead frame can be constructed in different ways. Thus, the leadframe can be punched out of a metal sheet (leat frame) or from a printed circuit board carrying conductor tracks.
Zur einfachen Montage kann der Träger die Kammer des Gehäuses verschließend mittels Schrauben mit dem Gehäuse verbindbar sein.For simple assembly, the carrier can be connected to the housing by means of screws, closing the chamber of 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. can be used on accelerator pedal modules. A preferred use is that the device is a throttle valve assembly for an internal combustion engine, in particular of a motor vehicle, and a continuous throttle opening is formed in the housing, which can be shut off by a throttle valve arranged on a throttle valve shaft, an electromotive drive being arranged in the housing which is pivotally drivable, in particular via a gearbox.
Dabei kann der Sensor ein die Stellung der Drosselklappenwelle oder des Getriebes erfassender Stellungssensor sein.The sensor can be a position sensor that detects the position of the throttle valve shaft or the transmission.
Eine kontaktlose Stellungserfassung des Getriebes ist dabei auf einfache Weise möglich, wenn der Sensor ein magneto- resistiver Sensor oder ein Hall-Sensor ist. Die zumindest eine oder weiteren Kontaktzungen können ein Motorstecker zur Kontaktierung des elektromotorischen Antriebs sein.Contactless position detection of the transmission is possible in a simple manner if the sensor is a magnetoresistive sensor or a Hall sensor. The at least one or further contact tongues can be a motor connector for contacting the electromotive drive.

The drive pinion rotatably drives the throttle valve shaft 4 via a gear. The housing cover 8 has a plate-like carrier 9, which is an insulating plastic injection molded part, a sleeve-like connector receptacle 10 for contacting 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.
