Abstract
Vorrichtung aufweisend – eine elektronische Baugruppe mit einer Leiterplatte (1), die mit wenigstens einem elektronischen Bauelement (14) bestückt ist und eine Thermosicherung (2) aufweist, und – einen Gegenstand (8), der mit der elektronischen Baugruppe zusammenfügbar ist, dadurch gekennzeichnet, dass die Thermosicherung (2) einen Abschnitt (3, 4) umfasst, wobei der Abschnitt (3, 4) mit einer Kontur am Gegenstand (8) derart zusammenwirkt, dass der Abschnitt (4) während der Fügebewegung der Leiterplatte (1) mit dem Gegenstand (8) auf einer Oberfläche der Kontur (9) gleitet und dabei mechanisch vorgespannt wird.Device comprising - an electronic assembly with a printed circuit board (1) which is equipped with at least one electronic component (14) and a thermal fuse (2), and - an object (8) which is joined to the electronic assembly, characterized in that the thermal fuse (2) comprises a section (3, 4), wherein the section (3, 4) interacts with a contour on the object (8) such that the section (4) engages with the circuit board (1) during the joining movement the article (8) slides on a surface of the contour (9) and is thereby mechanically biased.
Description
Die Erfindung betrifft eine Vorrichtung mit einer elektronischen Baugruppe gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device with an electronic assembly according to the preamble of
Elektronische Baugruppen im Bereich der Fahrzeugelektronik enthalten vielfach Leistungsbauelemente, die einen sehr hohen Strom führen können. Bei einem Defekt der Leistungsbauelemente kann es dazu kommen, dass die Baugruppe überhitzt und im schlimmsten Fall zerstört wird. Bekannte elektronische Baugruppen werden daher mit Thermosicherungen ausgestattet, die den Stromkreis bei Überschreiten einer vorgegebenen Grenztemperatur unterbrechen.Electronic assemblies in the field of vehicle electronics often contain power components that can carry a very high current. In case of a defect of the power components, it may happen that the assembly is overheated and destroyed in the worst case. Known electronic assemblies are therefore equipped with thermal fuses that interrupt the circuit when a predetermined limit temperature is exceeded.
Eine solche Thermosicherung ist beispielsweise aus der
Es ist daher die Aufgabe der vorliegenden Erfindung, eine eine Vorrichtung mit einer elektronischen Baugruppe mit einer Thermosicherung zu schaffen, die einfacher aufgebaut ist und insbesondere ohne zusätzliche Bauteile, wie z. B. eine Feder auskommt.It is therefore an object of the present invention to provide a device with an electronic assembly with a thermal fuse, which is simpler in construction and in particular without additional components such. B. manages a spring.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale. Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen. This object is achieved according to the invention by the features specified in
Ein wesentlicher Aspekt der Erfindung besteht in dem Vorschlag eine Leiterplatte mit einer Thermosicherung so auszustatten, dass sie während einer Fügebewegung, bei der die Leiterplatte und das Gehäuse oder ein Gehäusedeckel zusammengefügt werden, mechanisch vorgespannt wird. Die Thermosicherung wird also durch die Fügebewegung vorgespannt. Andere, gesonderte, Mittel oder Prozesse zum Vorspannen, wie z. B. eine Feder, sind nicht mehr erforderlich. Der Fertigungs- und Montageaufwand ist somit erheblich reduziert.An essential aspect of the invention is the proposal to equip a printed circuit board with a thermal fuse so that it is mechanically biased during a joining movement, in which the circuit board and the housing or a housing cover are joined together. The thermal fuse is thus biased by the joining movement. Others, separate, means or processes for tempering, such as. As a spring are no longer required. The production and assembly costs are thus considerably reduced.
Die Thermosicherung umfasst zu diesem Zweck bevorzugt einen Vorspann-Abschnitt.The thermal fuse preferably includes a bias section for this purpose.
Der Vorspann-Abschnitt umfasst vorzugsweise einen Hebelarm, der, beim Zusammenfügen von Leiterplatte und Gehäuse oder Gehäusedeckel, mechanisch ausgelenkt wird.The biasing portion preferably includes a lever arm that is mechanically deflected upon assembly of the circuit board and housing or housing cover.
Darüber hinaus kann die Thermosicherung bei einem Montageprozess vorgespannt werden, wenn die elektronische Baugruppe z. B. auf eine andere Baugruppe aufgesetzt wird.In addition, the thermal fuse can be biased in an assembly process when the electronic assembly z. B. is placed on another assembly.
Gemäß einer speziellen Ausführungsform der Erfindung umfasst die Thermosicherung einen Kippbereich, um den sie kippt, wenn die Grenztemperatur überschritten wird. Der Kippbereich ist vorzugsweise zwischen dem Vorspann-Abschnitt und der Kontaktfläche der Thermosicherung angeordnet. Der Kippbereich stützt sich vorzugsweise auf der Oberfläche der Leiterplatte ab.According to a special embodiment of the invention, the thermal fuse comprises a tilting area, around which it tilts when the limit temperature is exceeded. The tilting region is preferably arranged between the biasing section and the contact surface of the thermal fuse. The tilting area is preferably supported on the surface of the printed circuit board.
Der Vorspann-Abschnitt der Thermosicherung ist vorzugsweise flexibel gebildet. Wahlweise könnte aber auch der korrespondierende Abschnitt des Gegenstands flexibel ausgebildet sein.The biasing portion of the thermal fuse is preferably formed flexible. Alternatively, however, the corresponding section of the article could also be flexible.
Die Thermosicherung hat vorzugsweise einen flächigen Kontaktbereich, der stoffschlüssig unter Verwendung von einem Haftmittel mit der Oberfläche der Leiterplatte verbunden ist. Sobald die Grenztemperatur überschritten wird, löst sich der Kontaktbereich von der Leiterplatte, und unterbricht den Stromkreis.The thermal fuse preferably has a flat contact region, which is materially connected using an adhesive to the surface of the circuit board. As soon as the limit temperature is exceeded, the contact area releases from the circuit board and interrupts the circuit.
Als Haftmittel wird vorzugsweise herkömmliches Lot verwendet. Wenn der Kontaktbereich der Thermosicherung direkt mit der Leiterplatte verbunden ist, muss das Haftmittel elektrisch leitfähig sein.The adhesive used is preferably conventional solder. If the contact area of the thermal fuse is directly connected to the PCB, the adhesive must be electrically conductive.
Die Erfindung wird nachstehend anhand der beigefügten Zeichnungen beispielhaft näher erläutert. Es zeigen:The invention will now be described by way of example with reference to the accompanying drawings. Show it:
