Housing sealed against radio interference
Die Anmeldung betrifft ein funkstörstrahlungssieiier abgedichtetes, mindestens zweiteiliges metallenes Gehäuse. Derartige Gehäuse sind erforderlich für elektromagnetische Strahlen aussendende elektrische Bauelemente, die in solcher Nähe von Nachrichten- oder Informationen verarbeitenden elektrischer* Geräten oder Baugruppen angeordnet sind, dass die Funktionsweise derselben beeinträchtigt wird oder werden könnte. Nach den einschlägigen Vorschriften sind die erwähnten elektrischeil Bauelemente daher funkstörstrahlungssicher auszuführen.The application relates to a radio interference radiation sealed, at least two-part metal housing. Such housings are required for electrical electromagnetic radiation emitting Components that are arranged in such close proximity to electrical * devices or assemblies that process messages or information, that the functionality of the same is or could be impaired. According to the relevant regulations, the mentioned electrical parts Components should therefore be designed so that they are safe from radio interference.
Dies ist beispielsweise bei Antriebsmotoren für Pernschreibeinriehtungen der EaIl, die in ein wannenartig ausgebildetes Gehäuseunterteil eingesetzt sind, über welches ein ähnlich wie das Gehäuseunterteil ausgebildetes Gehäuseoberteil gestülpt ist. Beide Gehäuseteile sind dann funkstörstrahlungssicher abgedichtet, welches bei den bekannten Gehäusen in der aus Fig. 1 ersichtlichen Weise bewerkstelligt ist. Tn. Fig. 1 sjnd lediglich die für das Verständnis des Gehäuses unbedingt erforderlichen Teile, nämlich die aufeinanderliegenden Ränder der Gehäuseteile, gezeigt.This is for example with drive motors for Pernschreibeinriehtungen the EaIl, which are inserted into a trough-like housing lower part, over which a similar to the housing lower part trained upper housing part is turned upside down. Both housing parts are then sealed against radio interference, which is the case with the known Housing in the manner shown in Fig. 1 is accomplished. Tn. Fig. 1 are only those for understanding the housing absolutely necessary parts, namely the overlapping edges the housing parts shown.
Wie aus Fig. 1 ersichtlich, ist der Rand des Gehäuseunterteils 1 etwas verbreitert und als glatte Auflageflache ausgebildet. Der Rand des Gehäuseoberteils 2 ist ebenfalls verbreitert und mit einer im verbreiterten Rand eingelassenen Nut versehen. Bei den bekannten Gehäusen ist die funkstörstrahlungssiehere Abdichtung zwischen den Gohäuseteilen 1 und 2 dadurch hergestellt, dass in die Nut ein mit Metallgefleoht umsponnener Schlauch 3 aus Kunststoff oder Gummi eingelegt ist.As can be seen from Fig. 1, the edge of the lower housing part 1 is somewhat widened and designed as a smooth support surface. The edge of the Upper housing part 2 is also widened and provided with a groove embedded in the widened edge. With the known housings is the radio interference radiation-free seal between the Gohäuseteile 1 and 2 produced in that a metal braided into the groove braided hose 3 made of plastic or rubber is inserted.

Die bekannte Lösung hat einmal den Nachteil, dass zur funlsbörstrahlungssioheren Abdichtung des Gehäuses zusätzliche Mittel, nämlich der mit Met&llgefleoht umsponnene Schlauch 3» erforderlich sind und zum anderen, dass die Montage dieser zusätzlichen Mittel in aufwendiger Weise durch Handarbeit vorgenommen werden muss und eine rationelle Fertigung beeinträchtigt.The known solution has the disadvantage that additional means, namely the tube 3 »braided with metal braided are required and on the other hand, that the assembly of these additional means has to be done by hand in a complex manner and affects efficient production.
Bei dem neuen funkstörstrahlungssicher abgedichteten Gehäuse, bei dem neuerungsgemäss ein Gehäuseteil mit einer an dessen gesamtem Rand verlaufenden Nut und das andere Gehäuseteil mit einer an dessen gesamtem Rand verlaufenden. In die Nut passenden Zunge versehen sind, sind die erwähnten Nachteile nicht mehr vorhanden, weil durch die entsprechende Ausgestaltung von Ober- und Unterteil des Gehäuses eine elektrisch gut leitende Verbindung zwischen beiden hergestellt ist.In the case of the new radio interference-proof sealed housing, in which According to the innovation, a housing part with a groove running over its entire edge and the other housing part with one over its entire edge Edge running. Tongues that fit into the groove are provided The disadvantages mentioned no longer exist because the corresponding design of the upper and lower parts of the housing means that they are electrically good A conductive connection is established between the two.
Die neuerungsgemässe Ausgestaltung ist aus Flg. 2 ersichtlich, welche wieder die Ausbildung des Randes des Gehäuseunterteils 1 und des Gehäuseoberteils 2 zeigt. Der Rand des Gehäuseunterteils 1 ist mit der in die Nut 4 passenden Zunge 5 versehen. Die Neuerung erfordert für die funkstörstrahlungssichere Abdichtung des Gehäuses keinerlei zusätzliche Aufwendungen, weil die Zunge 5 bei der Herstellung des Gehäuseunterteils 1, beispielsweise als Leichtmetallspritzgussteil, im gleichen Arbeitsgang mit&eformt ist.The design according to the innovation is from Flg. 2 you can see which again shows the formation of the edge of the lower housing part 1 and the upper housing part 2. The edge of the lower housing part 1 is with the tongue 5 that fits into the groove 4. The innovation requires for the radio interference-proof sealing of the housing no additional expenses, because the tongue 5 in the manufacture of the housing lower part 1, for example as a light metal injection molded part, is formed with & e in the same operation.
