Description
Die Erfindung betrifft ein Gehäuse mit einem Deckel für eine elektronische Baugruppe, insbesondere eine elektronische Kraftfahrzeug-Baugruppe gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a housing a lid for an electronic assembly, in particular an electronic motor vehicle assembly according to the preamble of claim 1.
Bisher wurden elektronische Kraftfahrzeug-Baugruppen, insbesondere für Anti-Blockier-Systeme, Airbags, Fahrwerksregelungen, in ein Gehäuse eingebaut, die an der Öffnung, welche vom Deckel bedeckt werden soll, eine Nut oder andere Aussparung aufweisen. Die Nut befindet sich im Innern der Gehäusewand zwischen der äußeren und der inneren Gehäusewandfläche. Diese Nut bzw. Aussparung dient hierbei zur Positionierung des Deckels. Der Deckel ist bei diesen Aufbauten sehr flach und weist keine Seitenwände, sondern nur eine federartige Vorrichtung auf, die in die Nut eingelegt werden kann. Zum Verschließen wird die Nut mit Klebstoff aufgefüllt. Die Nut in der Gehäusewand dient somit gleichzeitig als Klebefuge und Kleberdepot. In diese Klebefuge wird der Deckel mit der federartigen Vorrichtung eingeklebt, um die elektronische Baugruppe vor schädlichen Umwelteinflüssen zu schützen. Vor dem Verschließen des Gehäuses mit dem Deckel wird als zusätzlicher Schutz die im Gehäuse montierte elektronische Kraftfahrzeug-Baugruppe mit einer Vergußmasse überzogen, wobei die Vergußmasse die Kraftfahrzeug-Baugruppe aus Kostengründen nur knapp bedeckt. Beim Verschließen des Gehäuses mittels Deckel bildet sich eine Luftschicht zwischen Deckel und Vergußmasse aus.So far, electronic motor vehicle assemblies, especially for Anti-lock braking systems, airbags, chassis controls, built into a housing, the one at the opening, which should be covered by the lid, a groove or other recess exhibit. The groove is located inside the housing wall between the outer and the inner housing wall surface. This Groove or recess serves to position the cover. The lid is very flat in these structures and has no side walls, but only a spring-like device, which are inserted into the groove can. To close the groove is filled with adhesive. The groove in the housing wall serves thus simultaneously as an adhesive joint and adhesive depot. In this glue line the lid with the spring-like device is glued to to protect the electronic assembly from harmful environmental influences. In front closing of the housing with the lid is used as an additional Protect those in the case assembled electronic motor vehicle assembly covered with a potting compound, taking the potting compound the motor vehicle assembly barely covered for cost reasons. At the Closing the housing an air layer is formed between the cover and the cover sealing compound out.
Nachteilig bei einem solchen Aufbau ist jedoch, daß der Deckel nicht fest in der Nut sitzt. Die Aushärtung des Klebers in der Nut wird durch Wärme zufuhr bewirkt. Dadurch dehnt sich auch die Luft im Gehäuseinnern aus und der Deckel wird dabei angehoben. Dadurch kann das Gehäuse undicht werden. Die elektronische Kraftfahrzeug-Baugruppe wird nicht mehr optimal geschützt, dies führt zu Fehlfunktionen oder zum Totalausfall des Gerätes.A disadvantage with such a structure is, however, that the Lid is not firmly seated in the groove. The hardening of the adhesive in the groove is supplied by heat causes. This also expands the air inside the housing and the cover is raised. This can cause the housing to leak. The electronic Motor vehicle assembly is no longer optimally protected, this leads to Malfunction or total failure of the device.
Die Druckschrift
Nachteilig hierbei ist jedoch, daß der Deckel den ersten Innenraum nicht wasser- und luftdicht verschließt und sich im zweiten Innenraum keine Vergußmasse befindet.The disadvantage here, however, is that the lid the first interior does not seal itself watertight and airtight there is no potting compound in the second interior.
Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Gehäuse mit Deckel diese Nachteile zu vermeiden und die Zuverlässigkeit beim Abdichten des Gehäuses zu erhöhen.The invention is therefore the object based on a housing with lid to avoid these disadvantages and reliability when sealing the housing to increase.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichen des Patentanspruchs 1 gelöst. Hierbei wird der Deckel in die Vergußmasse eingetaucht und dann durch einen Formschluß fest mit dem Gehäuse verbunden.This object is achieved by the Features solved in the characterizing part of patent claim 1. in this connection the lid is immersed in the sealing compound and then with a positive fit the housing connected.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß das Gehäuse fest und dicht mit dem Deckel verschlossen wird. Des weiteren können hierbei nicht nur Kunststoff-, sondern auch Metallteile verwendet werden, die die Baugruppe besser vor elektrischer oder elektromagnetischer Strahlung abschirmen.The advantages achieved with the invention consist of that casing tightly and tightly closed with the lid. Furthermore, you can not only plastic, but also metal parts are used, which the assembly better before electrical or electromagnetic Shield radiation.
Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen. Hierbei ist der Formschluß als Rastverschluß aufgebaut, der beim Eindrücken des Deckels in die Vergußmasse den Deckel am Gehäuse fixiert. Auch erweist es sich als vorteilhaft, wenn die Vergußmasse gelartig ist, so daß sie dem Druck beim Einbringen des Deckels standhält und nicht aus dem Gehäuse herausgedrückt werden kann. Für diesen Zweck ist besonders ausgehärtetes Silicon geeignet, welches nach dem Aushärten zwar nicht mehr fließt, aber dennoch seine Elastizität beibehält und sich immer wieder in die ursprüngliche Form zurückzieht.Advantageous further developments result themselves from the dependent Claims. Here is the form fit as Snap lock installed, the one when impressed the lid into the sealing compound the cover on the housing fixed. It also proves to be advantageous if the casting compound is gel-like is so that it withstands the pressure when inserting the cover and cannot be pushed out of the housing can. For this purpose is particularly suitable hardened silicone, which after curing no longer flows, but still its elasticity maintains and always retreats to its original form.
Im folgenden soll die Erfindung anhand von Ausführungsbeispielen im Zusammenhang mit den Figuren dargestellt und erläutert werden:In the following, the invention is to be illustrated using exemplary embodiments in connection with the Figures are shown and explained:
