Der Erfindung liegt die Aufgabe zugrunde eine Anordnung der gattungsgemäßen Art so auszubilden, dass sie eine elektromagnetische Abschirmung im Gehäuse bewirkt und einfache Herstellung der Teile und eine einfache und preiswerte Montage ermöglicht werden, wobei keine gesonderten Mittel zur Fixierung der Leiterplatte zu verwenden sind, so dass allein durch das Abnehmen des Deckels die Leiterplatte als solche zugänglich ist und z. B. ausgetauscht werden kann.Of the Invention is the object of an arrangement of the generic type form so that they have an electromagnetic shield in the casing causes and easy manufacture of the parts and a simple and easy inexpensive installation allows be, with no separate means for fixing the circuit board are to be used, leaving alone by removing the lid the circuit board as such accessible is and z. B. can be replaced.
Gelöst wird die Aufgabe durch Ausbildung der Anordnung nach der Erfindung gemäß der im Anspruch 1 angegebenen technischen Lehre.Is solved the task by forming the arrangement according to the invention according to the im Claim 1 specified technical teaching.
Die Verwendung eines Deckels in Form eines abgewinkelten Bleches, z. B. eines L-förmig abgewinkelten Bleches, ermöglicht bei gleichzeitigem Verschließen des Gehäuses, dass die elektronischen Bauelemente, die hohe Verlustleistung haben können, an die Kühlkörper durch den Deckel selbst angepresst werden, wobei diese Bauelemente entweder auf der Bestückungs- oder Lötseite der Leiterplatte als SMD-Bauteile angelötet oder angeschweißt sind. Es können auch Bauelemente, wie Transistoren, Thyristoren oder Leistungshalbleiter mit radialen Anschlussdrähten zugleich eingesetzt werden, die senkrecht zur Leiterplatte verlaufend in einem Abstand zu den anderen zu kühlenden Bauelementen stehen und im Randbereich des Abwinklungsteils angeordnet sind. Die senkrechten Bauteile müssen im Randbereich angeordnet sein. Dies ist erforderlich, da nur von der Außenseite her auf die Bauelemente gedrückt werden kann. Die waagerechten bzw. die an der Leiterplatte aufliegenden Bauelemente hingegen können verteilt platziert sein, müssen jedoch auch an Wärmeableitflächen des Gehäuses anliegen. Die Stützwände für diese Bauteile müssen also parallel zur Leiterplatte verlaufen.The Using a lid in the form of an angled sheet, z. B. an L-shaped Angled sheet, allows with simultaneous closure of the housing, that the electronic components that have high power dissipation can, to the heat sink through the lid itself be pressed, these components either on the assembly or solder side the PCB are soldered or welded as SMD components. It can also components, such as transistors, thyristors or power semiconductors with radial connecting wires be used at the same time, running perpendicular to the circuit board stand at a distance to the other components to be cooled and are arranged in the edge region of the Abwinklungsteils. The vertical Components must be arranged in the edge region. This is required as only from the outside pressed down on the components can be. The horizontal or resting on the circuit board By contrast, components can must be placed distributed but also on heat sinks of housing issue. The supporting walls for this Components must So run parallel to the PCB.
Vorteilhafte Weiterbildungen der Anordnung nach der Erfindung sind in den Unteransprüchen detailliert angegeben.advantageous Further developments of the arrangement according to the invention are detailed in the subclaims specified.
Durch die erfinderische Lehre ist der Vorteil gegeben, dass mit dem Verschließen des Gehäuse zugleich auch die Leistungsbauelemente in gewünschter Weise gegen die Kühlflächen des Kühlkörpers bzw. des Gehäuses gedrückt werden, über die die Verlustwärme abgeführt werden soll. Üblicherweise werden zu diesem Zweck die elektronischen Leistungsbauelemente in Reihe angeordnet, so dass ein Niederdrücken über eine kanalförmige Sicke erfolgen kann. Diese kann sowohl in den kurzen Seitenschenkeln als auch in den langen Seitenschenkel vorgesehen sein.Due to the inventive teaching has the advantage that with the closing of the housing at the same time the power components are pressed in a desired manner against the cooling surfaces of the heat sink and the housing, via which the heat loss is to be dissipated. Usually, for this purpose, the electronic power devices are arranged in series, so that a depression can be done via a channel-shaped bead. This can be both in the short side be provided as well as in the long side legs.
Bei der Montage wird wie folgt vorgegangen: Das Gehäuse, das in der Regel aus einem vorgefertigten Kühlkörper mit Aufnahmen für die Leiterplatte besteht, wird mit der Öffnungsseite nach oben auf einen Montageuntergrund gelegt. Dabei kommen die flachen Bauelemente, die an der Leiterplatte befestigt sind, entweder mit ihrer Unterseite in Eingriff mit einer Stützwand des Gehäuses oder liegen obenseitig auf der Leiterplatte. Das senkrecht zur Leiterplatte stehende Bauteil hingegen wird an eine Außenwand von außen angelegt und mittels des senkrechten Deckenschenkels gegen den Kühlkörper gedrückt, so dass auch hierüber eine optimale Wärmeableitung gegeben ist.at The assembly is proceeded as follows: The housing, which usually consists of a prefabricated heat sink with Recordings for the printed circuit board is made, opens with the opening side up placed a mounting surface. Here are the flat components, which are attached to the circuit board, either with its bottom in engagement with a supporting wall of the housing or lie on the top of the circuit board. The perpendicular to the circuit board In contrast, the component is applied to an outer wall from the outside and pressed by means of the vertical ceiling leg against the heat sink, so that also about this given an optimal heat dissipation is.
Die Erfindung wird nachfolgend anhand des in der Zeichnung dargestellten Ausführungsbeispiels ergänzend erläutert.The Invention will be described below with reference to the drawing Embodiment explained in addition.
