Vorrichtung zur Masseverbindung von Flachbaugruppen an einer Gehäus ewandung
5Device for grounding flat modules on a housing wall
5

Die Erfindung betrifft eine Vorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a device according to the features of the preamble of claim 1.

Flachbaugruppen, beispielsweise sogenannte Systemboards von Personalcomputern, müssen an den Masseanschlüssen aus Gründen der elektromagnetischen Abschirmung gut leitend mit dem auf Massekontakt liegenden Gehäuse verbunden werden. Üblicherweise geschieht dies dadurch, daß die Flachbaugruppe bzw. das Systemboard an mehreren Stellen mit dem Gehäuse verschraubt werden, wobei die Schrauben zusätzlich auch zur mechanischen Befestigung dienen.Flat modules, for example so-called system boards of personal computers, must be connected to the housing, which is connected to the ground, in a well-conductive manner at the ground connections for reasons of electromagnetic shielding. This is usually done by screwing the flat module or system board to the housing at several points, with the screws also serving as mechanical fastening.

Da insbesondere Systemboards von Personalcomputern im zunehmendem Maße mittels Rast- oder Schnapphaken mechanisch befestigt werden, die Schraubverbindung aber wegen des Massekontaktes zum Gehäuse nach wie vor erforderlich ist, bedeutet dies zunächst keinen besonderen Vorteil bei der Montage. Hinzukommt, daß die für die Schraubverbindung jeweils erforderlichen Muttern in einem speziellen Arbeitsgang vorher an der Gehäusewandung befestigt werden müssen.Since system boards of personal computers in particular are increasingly being mechanically attached using locking or snap hooks, but the screw connection is still necessary because of the ground contact to the housing, this initially does not represent any particular advantage during assembly. In addition, the nuts required for the screw connection must first be attached to the housing wall in a special operation.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, für den mittels Schraubverbindung bewerkstelligten Masseanschluß von Flachbaugruppen, insbesondere von Systemboards 0 von Personalcomputern, eine einfache und bezüglich des Montageaufwands möglichst kostengünstige Lösung zu finden.The present invention is therefore based on the object of finding a simple and, in terms of assembly effort, as cost-effective solution as possible for the ground connection of flat modules, in particular of system boards 0 of personal computers, by means of a screw connection.

Erfindungsgemäß wird diese Aufgabe, ausgehend von einer Vorrichtung der eingangs genannten Art, durch die kennzeichnen-According to the invention, this object is achieved, starting from a device of the type mentioned at the outset, by the characteristic

den Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.the features of claim 1. Advantageous developments of the invention are specified in subclaims.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Dabei zeigen:In the following, an embodiment of the invention is explained in more detail with reference to the drawing.

Figur 1 eine perspektivische Explosionsdarstellung für eine erfindungsgemäß ausgebildete Vorrichtung,Figure 1 is a perspective exploded view of a device designed according to the invention,

Figur 2 eine Draufsicht der Gehäusewandung im Bereich der Vorrichtung gemäß Figur 1,Figure 2 is a plan view of the housing wall in the area of the device according to Figure 1,

Figur 3 eine Schnittdarstellung der Vorrichtung längs der Schnittlinie III-III.Figure 3 is a sectional view of the device along the section line III-III.

Die Figur 1 zeigt in einer perspektivischen Explosionsdarstellung einen Ausschnitt aus einer Gehäusewandung 1, einen Ausschnitt einer darüber im Abstand zu befestigenden Flachbaugruppe 2 und ein Befestigungselement 3. Die Flachbaugruppe ist üblicherweise an den Rändern durch Rast- bzw. Schnapphaken (in der Zeichnung nicht dargestellt) lösbar befestigt. Zur Masseverbindung zwischen Flachbaugruppe 2 und Gehäusewandung 1 sind in der Flachbaugruppe 2 außerdem mehrere Befestigungsbohrungen 4 vorgesehen, über die der Kontakt zur Gehäusewandung hergestellt wird. Anstelle der bei Schraubverbindungen üblichen Mutter weist die Gehäusewandung 1 an den jeweils Befestigungsbohrungen 4 aufweisenden Masseanschlüssen der Flachbaugruppe 2 jeweils eine aus der Ebene der Gehäusewandung 1 hervorstehende, nach Art eines Düsenkopfes ausgebildete Ausbuchtung 5 auf, deren zentrale Öffnung 6 als Teil eines Bajonettverschlusses ausgebildet ist. Das entsprechende Befestigungselement 3 als Gegenstück zum Bajonettverschluß ist als Drehknopf-Schnellverschluß mit Schlüsselbart 7 ausgebildet, mit dem Vorteil, daß die Montage bzw. Demontage ohne Werkzeug schnell und einfach durchgeführt werden kann.Figure 1 shows a perspective exploded view of a section of a housing wall 1, a section of a flat module 2 to be fastened above it at a distance, and a fastening element 3. The flat module is usually detachably fastened at the edges by means of locking or snap hooks (not shown in the drawing). For the ground connection between the flat module 2 and the housing wall 1, several fastening holes 4 are also provided in the flat module 2, via which contact is made with the housing wall. Instead of the nut that is usual for screw connections, the housing wall 1 has a bulge 5 protruding from the plane of the housing wall 1 on the ground connections of the flat module 2, each of which has fastening holes 4 and is designed like a nozzle head, the central opening 6 of which is designed as part of a bayonet lock. The corresponding fastening element 3 as a counterpart to the bayonet lock is designed as a rotary knob quick-release lock with a key bit 7, with the advantage that assembly and disassembly can be carried out quickly and easily without tools.

Dieser Drehknopf-Schnellverschluß besteht selbstverständlich aus elektrisch leitendem Material, insbesondere aus elektrisch leitendem Kunststoff, aus Metalldruckguß oder dergleichen. Der Kopf des Drehknopf-Schnellverschlusses ist wahlweise mit einer diametral verlaufenden Quernut 8 als Führungselement für eine Mütze oder mit einem Griffelement versehen. Dieses Griffelement ist vorzugsweise als diametral verlaufender Quersteg 9 ausgebildet.3
This rotary knob quick fastener is of course made of electrically conductive material, in particular of electrically conductive plastic, of die-cast metal or the like. The head of the rotary knob quick fastener is optionally provided with a diametrically running transverse groove 8 as a guide element for a cap or with a handle element. This handle element is preferably designed as a diametrically running transverse web 9.

Die Figur 2 zeigt die Draufsicht auf die Gehäusewandung 1 im Bereich der Ausbuchtung 5, in deren zentraler Öffnung 6 zwei Führungslappen 10, 11 für den Bajonettverschluß vorgesehen sind. Aus der etwas vergrößerten Schnittdarstellung in Figur 3 ist ersichtlich, daß der Lappen 10, ebenso wie der nicht sichtbare Lappen 11, schräg nach unten abfallend geprägt ist. Dadurch wird eine Vorspannung beim Schließen des Schnellverschlusses erreicht. Das nach unten gebogene freie Ende der Lappen 10, 11 dient außerdem als Anschlag für den nach dem Einsetzen des Drehknopf-Schnellverschlusses um 90° gedrehten 0 Schlüsselbart 7,Figure 2 shows the top view of the housing wall 1 in the area of the bulge 5, in whose central opening 6 two guide tabs 10, 11 are provided for the bayonet lock. From the slightly enlarged sectional view in Figure 3 it can be seen that the tab 10, like the invisible tab 11, is embossed to slope downwards. This creates a pre-tension when the quick-release fastener is closed. The free end of the tabs 10, 11, which is bent downwards, also serves as a stop for the key bit 7, which is rotated by 90° after the rotary knob quick-release fastener has been inserted.
