Abstract

The wall of a casing and partic. one of a box to hold electrical or electronic components, is produced with a hole and an injection moulded inspection window over that hole. The rim of the hole has a circumferential groove or shoulder, in or on which it holds an elastic sealing ring; the window is then injected so that it lies against the ring and compresses it in doing so. Pref. the box has a cover (2) held on by four corner screws (3). At its centre the cover (2) has a circular hole (2c) with a circumferential groove (2a) running all round. This groove (2a) holds an O-ring (5). The inspection window (4) is injection moulded in position so that its faces are flush with those of the cover (2). The window (4) has a circumferential rib which fits against the O-ring (5) and thus fills the rest of the groove (2a). This window (4) is injection moulded in position; when it subsequently shrinks it is still sealed by the ring (5). ADVANTAGE - The method makes a tight joint between the seal and window, even if the window is made of a different material from that of the casing itself.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Wandung, insbesondere der Wandung eines Gehäuses, für den Einbau von elektrischen oder elektronischen Bauelementen, die einen Durchbruch und einen den Durchbruch ver­ schließenden, als gespritztes Kunststoffteil ausgebildetes Sichtfenster aufweist sowie ein nach diesem Verfahren hergestelltes Gehäuse.The invention relates to a method for producing a Wall, especially the wall of a housing for Installation of electrical or electronic components, a breakthrough and a breakthrough closing, designed as an injection molded plastic part Has viewing window and one using this method manufactured housing.

Bei Gehäusen mit Sichtfenstern werden üblicherweise die Gehäuse mit den Aussparungen für die Sichtfenster zunächst hergestellt. Anschließend werden die als Kunststoffspritz­ gußteile ausgebildeten Sichtfenster in die vorgesehene Öffnung eingesteckt oder eingerastet. Eine solche Her­ stellung erfolgt sowohl bei Gehäusen aus Metall, wie bei­ spielsweise Blechgehäusen, als auch bei Gehäusen, die als Kunststoffspritzgußteile ausgebildet sind. Ein wesentli­ cher Nachteil dieser bekannten Gehäuse besteht darin, daß sie am Übergang zwischen den Sichtfenstern und der Ge­ häuseaussparung nicht eine für alle Fälle ausreichende Dichtigkeit aufweisen.For housings with viewing windows, the Housing with the cutouts for the viewing window first produced. Then the plastic injection Cast parts trained viewing window in the intended Opening inserted or snapped into place. Such a fro position takes place both with metal housings, as with for example sheet metal housings, as well as housings that as  Plastic injection molded parts are formed. An essential The disadvantage of this known housing is that they at the transition between the viewing windows and the Ge recesses in the house are not sufficient for all cases Have tightness.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der als bekannt vor­ ausgesetzten Art so auszubilden, daß das Sichtfenster dicht in die Einsparung eingepaßt ist. Die geforderte Dichtigkeit soll auch dann gewährleistet sein, wenn die Materialien des Sichtfensters und der Wandung unter­ schiedlich sind.The invention is based on this prior art based on the task of a process known as prior exposed type so that the viewing window is tightly fitted into the savings. The required Tightness should also be guaranteed if the Materials of the viewing window and the wall below are different.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß in eine im oder am Rand des Durchbruchs vorgesehen um­ laufende Nut oder in einen umlaufenden Absatz ein elasti­ scher Dichtring eingelegt und anschließend das Sicht­ fenster derart in den Durchbruch eingespritzt wird, daß sich das Sichtfenster rings umlaufend gegen den elasti­ schen Dichtring anlegt und diesen beim Spritzvorgang zusammendrückt.According to the invention, this object is achieved by that provided around in or at the edge of the opening running groove or in a circumferential paragraph an elastic sheared sealing ring and then the view window is injected into the opening such that the viewing window runs all around against the elastic put on the sealing ring and this during the spraying process squeezing.

Mit einem derartigen Verfahren läßt sich eine zuverlässige und dichte Verbindung zwischen Sichtfenster und Wandung erzeugen. Der beim Spritzvorgang zusammengedrückte Dicht­ ring kann einen Schwund des Kunststoffs zuverlässig aus­ gleichen.A reliable method can be achieved with such a method and tight connection between the viewing window and the wall produce. The seal compressed during the spraying process ring can reliably shrink the plastic same.

Zunächst zu Fig. 1 und 2First to Figs. 1 and 2

Das dargestellte Gehäuse besitzt ein Gehäuseunterteil 1, das mittels des Deckels 2 und der Verbindungsschrauben 3 verschließbar ist. Der Deckel 2 besitzt in seinem Zentrum einen Durchbruch 2c, der über das Sichtfenster 4 ver­ schlossen ist. Der Durchbruch 2c besitzt einen kreisrunden Randbereich in dem eine umlaufende Nut 2a vorgesehen ist. The housing shown has a lower housing part 1 , which can be closed by means of the cover 2 and the connecting screws 3 . The lid 2 has an opening 2 c in its center, which is closed via the viewing window 4 ver. The opening 2 c has a circular edge area in which a circumferential groove 2 a is provided.

In die Nut 2a ist ein Dichtring 5 eingelegt. Das Sicht­ fenster 4 ist bündig sowohl mit der Frontseite des Deckels 2 als auch mit deren Rückseite gespritzt. Eine umlaufende Rippe 4a schließt sich dicht an den Dichtring 5 an und füllt den durch den Dichtring 5 nicht belegten Bereich der Nut 2a aus. Beim Spritzgußvorgang drückt die sich bildende Rippe 4a den Dichtring 5 in radialer Richtung fest gegen den Nutgrund. Bei einem anschließenden Schwinden kann der elastische Dichtring 5 die Schwindungsmaße ausgleichen.In the groove 2 a, a sealing ring 5 is inserted. The view window 4 is injected flush with both the front of the cover 2 and with the back. A circumferential rib 4 a closely adjoins the sealing ring 5 and fills the area of the groove 2 a not occupied by the sealing ring 5 . During the injection molding process, the rib 4 a that forms presses the sealing ring 5 firmly against the groove base in the radial direction. In the event of a subsequent shrinkage, the elastic sealing ring 5 can compensate for the shrinkage dimensions.

The viewing window 4 'be a flange area 2 d provided on the rear side and a flange area 2 e provided on the front side. The flange area 2 d overlaps the edge 2 b 'on the back. The flange area 2 e overlaps not only the edge area 2 b ', but also the groove 2 a' on the front side. A rib 4 a ', which is ent during the injection molding process, presses the sealing ring 5 firmly into the circumferential groove 2 a'.

Bei der Ausführungsform gemäß Fig. 5 und 6 ist im Rand 2b′′ des Durchbruchs 2c′′ ein zur Frontseite gerichteter umlaufender Absatz 2f vorgesehen. In den Absatz 2f ist ein Dichtring 5 eingelegt. Auf der Innenseite des Deckels 2′′ übergreift ein Flanschbereich 2d′ den Rand 2b′′. Bei dieser Ausführungsform liegt die Frontseite des Sicht­ fensters 4′′ bündig mit der Frontseite des Deckels 2′′. Der dem Absatz benachbarte Bereich 4a′′ drückt beim Spritzgußvorgang den Dichtring 5 zusammen und füllt den nicht durch den Dichtring 5 belegten Freiraum des Absatzes 2f.In the embodiment of FIGS. 5 and 6 is provided in the edge 2 b '' of the opening 2 c '' is directed to the front side circumferential shoulder 2 f. In the paragraph 2 f, a sealing ring 5 is inserted. On the inside of the lid 2 '' overlaps a flange area 2 d 'the edge 2 b''. In this embodiment, the front of the viewing window 4 '' is flush with the front of the lid 2 ''. The area adjacent to the paragraph 4 a '' compresses the sealing ring 5 during the injection molding process and fills the space of the paragraph 2 f not occupied by the sealing ring 5 .

Die Erfindung wurde vorstehend anhand der Zeichnung am Beispiel eines Gehäuses erläutert. Statt bei einer Gehäu­ sewandung kann die Ausbildung auch bei anderen Wandungen in gleicher Weise verwendet werden, beispielsweise bei Schalttafeln, Schaltschränken oder dergleichen, welche dicht eingepaßte Sichtfenster benötigen.The invention was described above with reference to the drawing Example of a housing explained.
