Description
Die Erfindung betrifft eine Einrichtung zur Kontaktierung einer Platine einer elektronischen Steuereinrichtung eines Stellgliedes, insbesondere einer Drosselklappe einer Brennkraftmaschine eines Kraftfahrzeuges, wobei die Steuereinrichtung und das Stellglied eine bauliche Einheit bilden, mit auf einem ersten Bauteil angeordneten Kontakten und mit an einem zweiten Bauteil angeschlossenen, mit den Kontakten des ersten Bauteils leitend verbundenen Kontakten.The invention relates to a device for contacting a circuit board electronic control device of an actuator, in particular a throttle valve an internal combustion engine of a motor vehicle, the control device and the actuator form a structural unit, with on a first Components arranged contacts and with connected to a second component, contacts conductively connected to the contacts of the first component.
Bei zur Regelung der Leistung der Brennkraftmaschine von Kraftfahrzeugen eingesetzten Drosselklappen sind meist eine oder mehrere Platinen der elektronischen Steuereinrichtung in einem topfförmigen Gehäuse angeordnet. Das Gehäuse ist einteilig mit einem die Drosselklappe lagernden Drosselklappenstutzen gefertigt und wird von einem Deckel verschlossen. Der Drosselklappenstutzen hat einen Flansch zur unmittelbaren Verschraubung mit der Brennkraftmaschine. In dem Deckel sind Anschlußkontakte für das Bordnetz und für Signalleitungen angeordnet. Hierdurch ist der Drosselklappenstutzen mit allen zur Regelung der Leistung erforderlichen Bauteilen wie den Platinen und dem Deckel mit den Anschlußkontakten sehr kompakt aufgebaut. For regulating the performance of the internal combustion engine of motor vehicles Throttle valves used are usually one or more electronic circuit boards Control device arranged in a pot-shaped housing. The The housing is in one piece with a throttle valve body that supports the throttle valve manufactured and is closed by a lid. The throttle body has a flange for direct screwing to the internal combustion engine. In the cover there are connection contacts for the vehicle electrical system and for Signal lines arranged. This makes the throttle body with all components required to regulate the output, such as the circuit boards and the Lid with the connection contacts very compact.
Die Platinen und die Anschlußkontakte des Deckels werden an ihren Kontakten untereinander und mit einem Stellmotor für die Drosselklappe elektrisch kontaktiert. Da die Kontaktierung insbesondere bei den in dem Drosselklappenstutzen befestigten Platinen hohen Temperaturen und Vibrationen standhalten muß, werden die Kontakte meist durch Laserschweißen miteinander verbunden. Das Laserschweißen ist jedoch sehr aufwendig und führt zu einer sehr kostenintensiven Montage des Drosselklappenstutzens.The circuit boards and the connection contacts of the cover are on their contacts electrically contacted with each other and with a servomotor for the throttle valve. Because the contacting in particular in the throttle body the printed circuit boards withstand high temperatures and vibrations the contacts are usually connected to one another by laser welding. However, laser welding is very complex and leads to a very costly assembly of the throttle body.
Der Erfindung liegt das Problem zugrunde, eine Einrichtung der eingangs genannten Art so zu gestalten, daß sich die elektrische Verbindung der Kontakte möglichst kostengünstig gestaltet und daß anschließend die Verbindung hohen Temperaturen und Vibrationen besonders zuverlässig standhält.The invention is based on the problem of a device of the type mentioned Art to design so that the electrical connection of the contacts designed as inexpensively as possible and that the connection then high Withstands temperatures and vibrations particularly reliably.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die Kontakte des zweiten Bauteils auf einem Halteteil angeordnet sind, daß das Halteteil gegen das erste Bauteil vorgespannt ist und daß das zweite Bauteil über elastische Anschlußleitungen mit dem Halteteil verbunden ist.This problem is solved according to the invention in that the contacts of the second component are arranged on a holding part that the holding part against the first component is prestressed and that the second component is elastic Connection lines is connected to the holding part.
Durch diese Gestaltung erfolgt die Kontaktierung der Platine in einem Bereich, in dem keine mechanischen Belastungen auf die Verbindungsstelle einwirken. Deshalb führen Vibrationen nicht zu einer Reibung der Kontakte aneinander und damit nicht zu deren Zerstörung. Toleranzen zwischen den Bauteilen und Relativbewegungen der Bauteile zueinander werden von den Anschlußleitungen ausgeglichen. Damit weist die erfindungsgemäße Kontakteinrichtung eine besonders hohe Zuverlässigkeit auf. Da für die erfindungsgemäße Kontakteinrichtung keine Lötstellen erforderlich sind, ist diese insbesondere für den Einsatz an Brennkraftmaschinen von Kraftfahrzeugen geeignet.With this design, the circuit board is contacted in one area, in which there are no mechanical loads on the connection point. Therefore, vibrations do not cause the contacts to rub against each other and not to destroy them. Tolerances between the components and Relative movements of the components to each other are from the connecting lines balanced. The contact device according to the invention thus has a particularly high reliability. As for the contact device according to the invention no solder joints are required, this is especially for use suitable for internal combustion engines of motor vehicles.
Die Vorspannung des Halteteils könnte beispielsweise mit einer an dem ersten Bauteil angeordneten Klammer erfolgen. Zur Befestigung der Klammer an dem Halteteil ist jedoch beim Zusammenfügen der Bauteile ein zusätzlicher Arbeitsgang erforderlich. Die Vorspannung des Halteteils erfolgt gemäß einer vorteilhaften Weiterbildung der Erfindung ohne zusätzlichen Montageaufwand beim Zusammenfügen der Bauteile, wenn zwischen dem zweiten Bauteil und dem Halteteil ein Federelement zur Vorspannung des Halteteils gegen das erste Bauteil angeordnet ist.The pretensioning of the holding part could, for example, be one on the first Component arranged bracket take place. To attach the bracket to the However, the holding part is an additional step when assembling the components required. The holding part is preloaded according to an advantageous method Further development of the invention without additional assembly effort when Join the components when between the second component and the Holding part a spring element for biasing the holding part against the first Component is arranged.
Die erfindungsgemäße Einrichtung gestaltet sich besonders kostengünstig, wenn die elastischen Anschlußleitungen von auf einer Folie aufgedruckten Leiterbahnen gebildet sind.The device according to the invention is particularly cost-effective, if the elastic connecting cables are printed on a foil Conductor tracks are formed.
Die Fertigung des Halteteils als separates Bauteil führt nur zu einer unwesentlichen Erhöhung der Fertigungskosten der erfindungsgemäßen Einrichtung, wenn das Halteteil und das zweite Bauteil aus demselben Kunststoff gefertigt und über einen im Verhältnis zu ihren Materialstärken dünnen Steg miteinander verbunden sind. Der Steg kann hierbei wahlweise als Sollbruchstelle zwischen dem zweiten Bauteil und dem Halteteil dienen, oder elastisch, eine Relativbewegung der Bauteile zueinander ermöglichend gestaltet sein.The manufacture of the holding part as a separate component leads to only an insignificant Increase in the manufacturing costs of the device according to the invention, if the holding part and the second component are made of the same plastic and with each other via a thin bridge in relation to their material thickness are connected. The web can optionally be used as a predetermined breaking point between serve the second component and the holding part, or elastically, a relative movement the components are designed to enable each other.
Eine Relativbewegung des Halteteils gegenüber dem ersten Bauteil läßt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn das Halteteil Führungszapfen und das erste Bauteil den Führungszapfen entsprechende Bohrungen aufweist.A relative movement of the holding part with respect to the first component can be according to another advantageous development of the invention, simply avoid if the holding part guide pin and the first component the guide pin has corresponding holes.
Das Halteteil wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zuverlässig gegen das erste Bauteil vorgespannt, wenn das zweite Bauteil ein Führungselement für das Federelement hat. The holding part is according to another advantageous development of the invention reliably preloaded against the first component when the second component has a guide element for the spring element.
Die erfindungsgemäße Einrichtung gestaltet sich konstruktiv besonders einfach, wenn das Federelement eine Wendelfeder und das Führungselement eine Hülse ist.The device according to the invention is structurally particularly simple, if the spring element is a helical spring and the guide element is a sleeve is.
Die Kontakte könnten beispielsweise jeweils als Kontaktplättchen gestaltet sein. Zur Kontaktierung ließen sich einander gegenüberstehende Kontaktplättchen senkrecht gegeneinander vorspannen. Diese Gestaltung erfordert jedoch zur Vermeidung von Reibung zwischen den Kontakten sehr hohe Vorspannkräfte und eine besonders genaue Führung des Halteteils gegenüber dem ersten Bauteil. Eine Reibung zwischen den Kontakten würde zu einer Zerstörung der elektrisch leitenden Verbindung führen. Eine Reibung zwischen den Kontakten läßt sich jedoch gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Kontakte des zweiten Bauteils stiftförmig und die Kontakte des ersten Bauteils seitlich gegen die Kontakte des zweiten Bauteils vorgespannt sind. Die seitliche Vorspannung kann sehr einfach durch eine entsprechende Formgebung der Kontakte des ersten Bauteils erfolgen.For example, the contacts could each be designed as contact plates his. Opposing contact plates could be used for contacting pretension vertically against each other. However, this design requires very high preload forces to avoid friction between the contacts and a particularly precise guidance of the holding part relative to the first Component. Friction between the contacts would result in destruction of the electrically conductive connection. A friction between the contacts However, according to another advantageous development of the Simply avoid the invention if the contacts of the second component are pin-shaped and the contacts of the first component laterally against the contacts of the second component are biased. The side preload can be very simple by appropriate shaping of the contacts of the first component respectively.
