Abstract

The screening device has an outer screening frame (2) and a tear-off cover (5,6,7) attached to the outer screening frame via defined rupture points. The interior of the screening device is divided via at least one partition strut (3) into at least 2 screening chambers, with sheet metal strips soldered to the free edges of the partition struts used for fixing the tear-off cover, the partition struts connected to a screening potential via the circuit board of the screened electronic device.

Description

Die vorliegende Erfindung betrifft eine Schirmanordnung für elektronische Geräte, insbesondere Kommunikationsendgeräte, bestehend aus einem äußeren Schirmrahmen und einem Abreißdeckel, welcher über Sollbruchstellen mit dem Schirmrahmen verbunden ist.The present invention relates to a screen arrangement for electronic equipment, in particular communication terminals, consisting of an outer screen frame and a tear-off cover, which over predetermined breaking points is connected to the umbrella frame.

Eine derartige Schirmanordnung ist z.B. aus der US 6 384 324 B2 bekannt.Such a screen arrangement is for example from the US 6,384,324 B2 known.

Komponenten auf Leiterplatten von elektronischen Geräten werden auf Grund von EMV-Anforderungen (Anforderung an die elektromagnetische Verträglichkeit) mit Schirmanordnungen versehen, welche auf die Leiterplatte aufgelötet werden. Für den Fall, dass elektronische Komponenten ersetzt werden müssen, wird der Abreißdeckel, das heißt die obere Blechfläche, der Schirmanordnung abgerissen, da zwischen dem eigentlichen Abreißdeckel und dem Schirmrahmen Sollbruchstellen vorgesehen sind.Components on printed circuit boards from electronic devices are based on EMC requirements (requirement for electromagnetic compatibility) provided with screen arrangements which are soldered onto the circuit board. For the Case that electronic components will need to be replaced the tear-off cover, this means the upper sheet surface, the shield arrangement torn off, because between the actual tear-off cover and the screen frame predetermined breaking points are provided.

Werden bei einem elektronischen Gerät mehrere geschirmte Bereiche, das heisst, mehrere Schirmkammern, auf der Leiterplatte benötigt, so ist es bekannt, mehrere Schirmanordnungen auf die Leiterplatte zu löten.If there are several in one electronic device shielded areas, that is, several shielding chambers on which PCB needed it is known to have several shield arrangements on the circuit board to solder.

Bei der Verwendung von Einzelschirmkammern beziehungsweise einzelnen Schirmanordnungen, entsteht ein großer Abstand zwischen den Komponenten benachbarter Schirmanordnungen, da sich zwei Blechwandungen, eine je Schirmanordnung, zwischen den Komponenten befinden. Die Folge davon ist dann auch ein erhöhter Flächen- und Volumenbedarf im Gerät.When using single screen chambers or individual screen arrangements, there is a large distance between the components of adjacent shield arrangements, since there are two Sheet metal walls, one for each screen arrangement, between the components are located. The consequence of this is an increased space and volume requirement in the Device.

Aufgabe der vorliegenden Erfindung ist es, eine Schirmanordnung der eingangs genannten Art anzugeben, die bei einer Notwendigkeit von mehreren Einzelschirmkammern eine möglichst geringe Fläche auf der Leiterplatte beansprucht.Object of the present invention is to specify a screen arrangement of the type mentioned at the beginning, the one in the case of the need of several single shield chambers preferably small area stressed on the circuit board.

Diese Aufgabe wird für die eingangs genannte Schirmanordnung erfindungsgemäß dadurch gelöst, dass das Innere der Schirmanordnung mittels mindestens eines Trennsteges in mindestens zwei Kammern unterteilt ist, dass auf den freien Kanten der Trennstege Blechstreifen aufgelötet sind, mit denen über Sollbruchstellen den einzelnen Kammern zugeordnete Schirmdeckelteile befestigt sind, wobei die einzelnen Trennstege auf der Leiterplatte mit einem Schirmpotential verbunden sind.This task is for the beginning mentioned screen arrangement solved according to the invention in that the inside of the screen arrangement by means of at least one separating web is divided into at least two chambers that on the free edges of the Separators soldered to metal strips are with those over Screen break parts assigned to the individual chambers are attached, the individual dividers on the circuit board are connected to a shield potential.

Durch die Verwendung der erfindungsgemäßen Schirmanordnung mit mehreren Kammern aufgrund der Verwendung von integrierten Trennstegen kann der Flächen- und Volumenbedarf für eine Schirmanordnung, welche aus mehreren Einzelschirmkammern besteht, erheblich verringert werden.By using the screen arrangement according to the invention with multiple chambers due to the use of integrated dividers the area and volume requirements for a screen arrangement which consists of several single screen chambers, be significantly reduced.

Nachstehend wird eine Schirmanordnung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben.A screen arrangement is shown below of an embodiment shown in the drawing.

3, eine teilweise Schnittdarstellung der in den 1 und 2 dargestellten Schirmanordnung. 3 , a partial sectional view of the in the 1 and 2 screen arrangement shown.

In den Figuren ist der Aufbau einer erfindungsgemäßen Schirmanordnung, welche auf einer Leiterplatte 1 aufgebracht ist, dargestellt. Die Schirmanordnung besteht aus einem umlaufenden äusseren Schirmrahmen 2, welcher im Wesentlichen S-förmig ausgebildet ist und dessen unterer Schenkel auf der Leiterplatte aufgelötet und mit einem Schirmpotential verbunden ist.In the figures, the structure of a screen arrangement according to the invention, which is on a circuit board 1 is shown. The screen arrangement consists of an all-round outer screen frame 2 , which is essentially S-shaped and whose lower leg is soldered to the circuit board and connected to a shield potential.

Zwischen dem äußeren Schirmrahmen 2 sind Trennstege 3 vorgesehen, welche je nach bestehender Anforderung angeordnet sind. Diese Trennstege können zum Beispiel zwischen Teilen des Schirmrahmens 2 angeordnet sein oder aber zwischen einem Teil des Schirmrahmens 2 und einem Teil eines weiteren Trennstegs 3. Diese Trennstege können ebenfalls im Wesentlichen S-förmige Querschnitte aufweisen. Dabei sind die unteren Schenkel der Trennstege 3 ebenfalls auf der Leiterplatte 1 aufgelötet und mit dem Schirmpotential verbunden. Auf den oberen Schenkeln der Trennstege sind Blechstreifen 4 aufgelötet.Between the outer umbrella frame 2 are dividers 3 provided, which are arranged according to the existing requirement. These dividers can, for example, between parts of the screen frame 2 be arranged or between a part of the screen frame 2 and part of another divider 3 , These dividers can also have essentially S-shaped cross sections. The lower legs of the dividers 3 also on the circuit board 1 soldered and connected to the shield potential. There are metal strips on the upper legs of the dividers 4 soldered.

Zwischen dem äusseren Schirmrahmen 2 und den Blechstreifen 4 der Trennstege 3 sind jeweils Abreißdeckelteile 5, 6, 7 vorgesehen, welche die einzelnen Einzelschirmkammern abdecken.Between the outer umbrella frame 2 and the metal strip 4 the dividers 3 are each tear-off cover parts 5 . 6 . 7 provided, which cover the individual single screen chambers.

Zwischen den eigentlichen Abreißdeckelteilen 6, 7, 8 und dem äußeren Schirmrahmen 2, sowie den Blechstreifen 4 der Trennstege 3 sind Sollbruchstellen vorgesehen, so dass die Möglichkeit besteht, in einem Reparaturfalle die entsprechenden Abreißdeckelteile auszureißen.Between the actual tear-off cover parts 6 . 7 . 8th and the outer umbrella frame 2 , as well as the metal strip 4 the dividers 3 predetermined breaking points are provided, so that it is possible to tear out the corresponding tear-off cover parts in the event of a repair.

Bei dem dargestellten Ausführungsbeispiel sind statt dreier Einzelschirmkammern eine Kammer mit integrierten Trennstegen 3 vorgesehen, wodurch der Flächen- und Volumenbedarf auf der Leiterplatte 1 erheblich reduziert wird.In the illustrated embodiment, instead of three single-screen chambers, there is a chamber with integrated dividers 3 provided, whereby the area and volume requirements on the circuit board 1 is significantly reduced.
