Description

Die vorliegende Erfindung betrifft einen hochfrequenzdichten Deckel eines Gehäuses für Baugruppen der Hochfrequenztechnik, der federnd mit dem Gehäuse über am Deckelrand angeordnete in Verschlußrichtung abgewinkelte, am Gehäuse festrastende Laschen verbindbar ist.The present invention relates to a high-frequency-tight cover of a housing for assemblies the high-frequency technology, the resilient with the housing over arranged on the lid edge in the locking direction angled, latching tabs on the housing can be connected.

Ein derartiger Deckel ist aus dem Gebrauchsmuster DE-GM 69 38 874 bekannt Jener Deckel ist an seinen Rändern mit federnden Zungen versehen, die für einen guten Kontakt mit dem Gehäuse sorgen sollen. Die federnden Zungen sind durch Einschnitte in den Deckelrändern gebildet. Wegen der Einschnitte weist der Deckel aber keine sehr gute Hochfrequenzdichtigkeit auf.Such a cover is known from the utility model DE-GM 69 38 874. That cover is on his The edges are provided with springy tongues, which are intended to ensure good contact with the housing. the resilient tongues are formed by incisions in the lid edges. Because of the incisions but the lid does not have very good high frequency tightness.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Gehäusedeckel der eingangs genannten Art zu schaffen, der einen sicheren festen Sitz und dabei eint optimaleThe invention is now based on the object of creating a housing cover of the type mentioned at the outset, who has a secure, tight fit and at the same time unites optimally

Hochfrequenzdichtigkeit des Gehäuses gewährleistetHigh frequency tightness of the housing guaranteed

Die Aufgabe wird erfindungsgemäß dadurch gelöst daß zwischen Deckel und dem Gehäuse ein Federblech angeordnet ist und daß die Laschen am Ende eine sprungartige Verbreiterung besitzen, womit sie beim Aufsetzen des Deckels hinter am Gehäuse angeordnete, nasenförmig ausgebildete Ansätze greifen.The object is achieved according to the invention in that a spring plate between the cover and the housing is arranged and that the tabs have an abrupt widening at the end, which they when Put the cover on behind the nose-shaped lugs arranged on the housing.

Es ist zweckmäßig, daß das Ende der Verbreiterung an den Laschen nach außen vom Gehäuse weggebogen istIt is useful that the end of the widening at the tabs is bent outwards away from the housing is

Der erfindungsgemäße Decke! zeichnet sich durch eine sehr einfache Montage aus.The ceiling according to the invention! is characterized by a very simple assembly.

Anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, wird die Erfindung im folgenden näher beschrieben.Using an exemplary embodiment which is shown in the drawing, the invention is illustrated in FIG described in more detail below.

In der Figur ist ein Gehäuse 1 mit einem Deckel oben 2' und einem Deckel unten 2" in Seitenansicht dargestellt Die aus elastischem Material hergestellten Deckel ?.' und 2" haben an mindestens zwei Seiten je eine Lasche 3' bzw. 3". Zwischen Deckel 2 und Gehäuse 1 sind Federbleche 4' und 4" zwischengelegt die die Dichtigkeit gegen hochfrequente Signaleinstreuungen bewirken.The figure shows a housing 1 with a cover at the top 2 'and a cover at the bottom 2 "in a side view. The cover made of elastic material ?.' and 2 " each have a tab 3 'or 3" on at least two sides. Spring plates 4' and 4 "are placed between the cover 2 and the housing 1 to provide a seal against high-frequency signal interference.

Die Laschen 3' und 3" sind seitlich ausgespart 5', 5", d.h. sie besitzen an ihren Enden eine sprungartige Verbreiterung 3a', 3a". Beidseitig jeder Lasche befinden sich am Gehäuse nasenförmige Ansätze 6a', 6b'und 6a", 6b". Beim Aufsetzen des Deckels 2' bzw. 2" auf das Gehäuse greifen die Verbreiterungen 3a' 3a" der Laschen 3', 3" hinter diese nasenförmigen Ansätze.The tabs 3 'and 3 "are laterally recessed 5', 5", ie they have a step-like widening 3a ', 3a "at their ends. On both sides of each tab there are nose-shaped attachments 6a', 6b 'and 6a", 6b on the housing " When the cover 2 'or 2" is placed on the housing, the widenings 3a' 3a "of the tabs 3 ', 3" grip behind these nose-shaped extensions.

Das zwischengelegte Federblech 4', 4" drückt denThe intermediate spring plate 4 ', 4 "presses the

Deckel leicht nach oben, so daß die Verbreiterungen an den Laschenenden sich gegen die nasenförmigen Ansätze drücken und dem Deckel einen festen Sitz verleihen.Cover slightly upwards so that the widenings at the ends of the tabs are against the nose-shaped ones Press the approaches and give the lid a tight fit.

Die Enden der Verbreiterungen an den Laschen sind der besseren Handhabung wegen nach außen hin abgebogen T, 7". The ends of the widenings on the tabs are bent outwards T, 7 "for better handling.

In der Figur sind weiterhin am Gehäuse 1 Anschlüsse 8 für Hochfrequenzleitungen eingezeichnet.In the figure, connections 8 for high-frequency lines are also shown on the housing 1.
