Abstract

The electrical equipment casing (1) receives two preformed covers (2), each with a 90 degree projection (3) containing a rectangular slot (5', 5"). The covers locate on the casing through a projection (6', 6") aligning with the slot. Retention of the covers is provided by strip spring elements (4', 4") located between covers and housing. Electrical connectors (8) are coupled to the equipment casing. A small formed projection facilitates removal of the covers. The covers are made of flexible material so that they may distort sufficiently to be snapped into place.

Description

Hochfrequenzdichter Deckel eines Gehäuses für Bau- High-frequency-tight cover of a housing for construction

gruppen der Hochfrequenztechnik Die vorliegende Erfindung befaßt sich mit einem hochfrequenzdichten Deckel eines Gehäuses für Baugruppen der Hochfrequenztechnik. Es ist üblich, derartige Deckel zum Abdichten gegen die Abstrahlung oder auch Aufnahme von außen hochfrequenter Signale fest mit dem Gehäuse zu verschrauben. Vielfach wird zusätzlich noch ein gefiedertes Blech mit Federwirkung zwischen Deckel und Gehäuse gelegt. Groups of Radio Frequency Engineering The present invention is concerned with a high-frequency-tight cover of a housing for assemblies of high-frequency technology. It is customary to have such covers for sealing against radiation or for inclusion from the outside of high-frequency signals to be screwed tightly to the housing. Multiple there is also a feathered sheet metal with spring action between the cover and Housing laid.

Die Verwendung von Schrauben verteuert nicht nur die Fertigung der einzelnen Teile,.sondern vergrößert zusätzlich noch die Nontagezeit solcher Gehäuse.The use of screws not only makes the production of the individual parts, but also increases the assembly time of such housings.

Aufgabe dieser vorliegenden Erfindung ist es, eine Verbilligung und Vereinfachung in Fertigung und Montage solcher Deckel herbeizuführen.The object of this present invention is to reduce the cost and To bring about simplification in the manufacture and assembly of such covers.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der aus einem elastischen Werkstoff bestehende Deckel an mindestens zwei Kanten je eine um mindestens 900 abgewinkelte und mit Aussparungen versehene Lasche hat, die beim Aufsetzen des Deckels hinter mindestens je eine vorstehende keilförmig ausgebildete Nase des Gehäuses rastet.According to the invention this object is achieved in that the one elastic material existing cover on at least two edges each one by at least 900 has angled and recessed flap that opens when the Cover behind at least one protruding wedge-shaped nose of the housing snaps.

Zur Erhöhung der Strahlungsdichtigkeit trägt der Deckel an seiner Innenseite ein gegebenenfalls rundum mit Fiederung versehenes Federblech. Eine zweckmäßige Ausbildung des Erfindungsgedankens besteht darin, daß die Aussparung in der Lasche symmetrisch angeordnet und rechteckig ausgebildet und in einen nasenförmigen Ansatz des Gehäuses eingeklinkt ist, oder auch, daß die beidseitig ausgesparte und geschmälerte Lasche zwischen zwei an dem Gehäuse angeordnete, nasenförmig ausgebildete Ansätze geführt und gerastet ist. Es ist zur besseren Handhabung des Deckels, wenn das Ende der Lasche nach außen abgebogen ist.To increase the radiation tightness, the cover carries on its Inside a spring plate, if necessary provided with feathering all around. A functional one Formation of the inventive concept is that the recess in the tab symmetrically arranged and rectangular and in a nose-shaped approach of the housing is latched, or that the recessed and narrowed on both sides Tab between two nose-shaped lugs arranged on the housing is guided and locked. It's for better handling of the lid when the end the tab is bent outwards.

Diese einfache Ausführungsform und Gestaltung des Deckels stellt eine wesentliche Verbilligung der Fertigung und vereinfachte Montage dar, zumal ein etwa erforderlicher elektrischer Abgleich der Baugruppe wesentlich verkürzt wird.This simple embodiment and design of the lid represents a substantial cheaper production and simplified assembly, especially one about required electrical adjustment of the assembly is significantly shortened.

Anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, wird die Erfindung noch näher beschrieben.Using an exemplary embodiment that is shown in the drawing is, the invention will be described in more detail.

In der Fig. 1 ist die Seitenansicht eines Gehäuses mit je einem Deckel von unten und von oben mit rechteckig ausgesparten Laschen und in der Fig. 2 ein Gehäuse, ebenfalls mit je einem Deckel von unten und von oben mit beidseitig ausgesparter und geschmälerter Lasche dargestellt.In Fig. 1 is the side view of a housing, each with a cover from below and from above with rectangular recessed tabs and in FIG. 2 Housing, also with a cover from below and from above with recesses on both sides and narrowed tab shown.

In der Fig. 1 ist ein Gehäuse 1 mit einem Deckel oben 2' und einem Deckel unten 2" in Seitenansicht dargestellt.In Fig. 1 is a housing 1 with a top cover 2 'and a Lid below 2 "shown in side view.

Die aus elastischem Material hergestellten Deckel 2' und 2" haben an mindestens zwei Seiten je eine Lasche 3' bzw.The lids 2 'and 2 "made of elastic material have on at least two sides a tab 3 'or

311. Zwischen Deckel 2 und Gehäuse 1 sind Federbleche i' und 4§' zwischengelegt, die die Dichtigkeit gegen hochfrequente Signaleinstreuungen bewirken. Die Laschen 31 bzw.311. Spring plates i 'and 4§' are placed between cover 2 and housing 1, which ensure tightness against high-frequency signal interference. The tabs 31 or

311 haben Aussparungen 5' bzw. 5" symmetrisch angeordnet und rechteckig ausgebildet, die in einem nasenförmigen Ansatz 6' bzw. 6", der keilförmig ausgebildet ist, einklinken. Damit wird erreicht, daß der Deckel 2 fest gegen das Federblech 4 gepreßt und zugleich arretiert ist.311 have recesses 5 'and 5 "symmetrically arranged and rectangular formed in a nose-shaped projection 6 'or 6 ", which is wedge-shaped is to latch. This ensures that the cover 2 firmly against the spring plate 4 is pressed and locked at the same time.

Die Laschen 3 sind zur besseren Handhabe nach außen hin abgebogen 7' bzw. 71'.The tabs 3 are bent outwards for better handling 7 'or 71'.

Das Gehäuse, das für Baugruppen für sehr hohe Frequenzen vorgesehen ist, hat an den Seiten Anschlüsse für Kabel 8. Weiter sind in diesem Ausführungsbeispiel Deckel mit an jeder Kante abgewinkelter Lasche darge stellt.The housing intended for assemblies for very high frequencies has connections for cables 8 on the sides. Next are in this exemplary embodiment Lid with angled tab at each edge is Darge.

In der Fig. 2 ist ein weiteres Ausführungsbeispiel des Erfindungsgedankens wiedergegeben. Hier sind jedoch die Laschen 3' und 3" beidseitig ausgespart 6a', 6b' bzw, 6a", 6b" und in der Mitte geschmälert. Sie werden dadurch in zwei mit einem Zwischenraum nebeneinander angeordnete nasenförmige Ansätze 6a', 6b1 bzw. 6a", 6b" geführt - die Aussparungen und die nasenförmigen Ansätze haben die gleichen Positionen, da sie zeichnerisch nicht unterscheidbar sind - durch ihre am Ende befindlichen Verbreiterungen 3a1 bzw. 3a" gerastet.In Fig. 2 is a further embodiment of the inventive concept reproduced. Here, however, the tabs 3 'and 3 "are recessed on both sides 6a', 6b 'or 6a ", 6b" and narrowed in the middle. You will be in two with one Nose-shaped projections 6a ', 6b1 or 6a ", 6b" arranged next to one another in space guided - the recesses and the nose-shaped extensions have the same positions, because they are not distinguishable from the drawing - by the ones at the end Widenings 3a1 or 3a "latched.

Ihre Enden sind ebenfalls der besseren Handhabung wegen nach außen hin abgebogen.Their ends are also on the outside for better handling turned down.
