Abstract

The invention relates to a plug-in connection between a printed-board connector (3) and a mating connector (13), said printed-board connector (3) being provided with a connector shield (6). Between the printed-board connector and the mating connector an I/O board (1) with an opening (2) is interposed via which the printed-board connector and the mating connector can be contacted and fastened to each other. Since the printed-board connector is not screwed together with the I/O board according to the most recent standard, a support element is provided which forces the I/O board (1) against the connector shield (6) of the printed-board connector (3) when the mating connector (13) is screwed together with the printed-board connector (3).

Description

Beschreibungdescription
Steckverbindungconnector
Die Erfindung betrifft eine Steckverbindung zwischen einem Leiterplattenstecker und einem Gegenstecker, wobei der Leiterplattenstecker eine Steckerschirmung z.B. m Form eines Schirmbleches oder einer Metallisierungsschicht aufweist und zwischen dem Leiterplattenstecker und dem Gegenstecker em I/O-Blech mit einer Öffnung vorgesehen ist, durch welche der Leiterplattenstecker und der Gegenstecker kontaktierbar und über Gewindebolzen und Schrauben aneinander festlegbar sind.The invention relates to a plug connection between a circuit board connector and a mating connector, the circuit board connector having a connector shield, e.g. m in the form of a shield plate or a metallization layer and between the circuit board connector and the mating connector em I / O plate is provided with an opening through which the circuit board connector and the mating connector can be contacted and fixed to one another by means of threaded bolts and screws.
Derartige Steckverbindungen treten m der Regel m PCs auf, wobei der Leiterplattenstecker auf einer Baugruppenkarte oder dem Motherboard angeordnet ist und der Gegenstecker an einem Kabel, welches zum Drucker, zur Maus, zum Bildschirm oder zu einer anderen externen Komponente führt, angeschlossen ist.Such plug connections usually occur in m PCs, the circuit board connector being arranged on a module card or the motherboard and the mating connector being connected to a cable which leads to the printer, mouse, screen or other external component.
Das I/O-Blech stellt m der Regel die Rückseite des PCs dar und dient zum einen als Gehäusewand und zum anderen auch als Steckerschirmung gegen elektromagnetische Einflüsse.The I / O plate usually represents the back of the PC and serves on the one hand as a housing wall and on the other hand as a connector shield against electromagnetic influences.
Um eine möglichst gute elektromagnetische Verträglichkeit (EMV) zu erzielen, ist es wichtig, daß die Steckerschirmung am Leiterplattenstecker mit dem I/O-Blech leitend verbunden und somit eine Massekontakt hergestellt ist.In order to achieve the best possible electromagnetic compatibility (EMC), it is important that the connector shield on the circuit board connector is conductively connected to the I / O plate and that a ground contact is thus established.
Bisher wurde dies dadurch erzielt, daß der Leiterplattenstek- ker mit seiner Steckerschirmung durch eine Öffnung im 1/0- Blech gesteckt und anschließend über Gewindebolzen, welche durch separate, neben der Öffnung ausgebildete Bohrungen von der anderen Seite des I/O-Blechs gesteckt wurden, verschraubt wurde. Durch die separat ausgebildeten Gewindebolzen, welche von der anderen Seite des I/O-Blechs m den Leiterplattenstecker geschraubt wurden, wurde der Leiterplattenstecker mit seiner Steckerschirmung gegen das I/O-Blech gezogen, wodurch eine gute Kontaktierung zwischen der Steckerschirmung des Leiterplattensteckers und dem I/O-Blechs gewährleistet wurde.So far, this has been achieved by inserting the plug connector with its shielding through an opening in the 1/0 plate and then using threaded bolts which have been inserted from the other side of the I / O plate through separate holes formed next to the opening was screwed. Through the separately formed threaded bolts, which were screwed from the other side of the I / O plate m the PCB connector, the PCB connector with its connector shield was pulled against the I / O plate, whereby good contact between the connector shield of the PCB connector and the I / O plate was guaranteed.
Bei der gattungsgemäßen Ausbildung nach dem neuen Standard, sind die Gewindebolzen bereits an dem Leiterplattenstecker befestigt und ist die Öffnung im I/O-Blech so groß ausgebildet, daß die kragenartig nach vorne vorspringende Steckerschirmung des Leiterplattensteckers zusammen mit den daran angeordneten Gewindebolzen durch die Öffnung gesteckt werden kann.In the generic design according to the new standard, the threaded bolts are already attached to the printed circuit board connector and the opening in the I / O plate is so large that the collar-like protruding connector shield of the printed circuit board connector is inserted through the opening together with the threaded bolts arranged thereon can be.
Der neue Standard erleichtert zwar die Montage erheblich, jedoch wird durch die Gewindebolzen keine sichere Kontaktierung zwischen der Steckerschirmung des Leiterplattensteckers und dem I/O-Blech erzielt.Although the new standard considerably simplifies assembly, the threaded bolts do not ensure reliable contact between the connector shield of the PCB connector and the I / O plate.
Je nach den Maßtoleranzen der Leiterplatte und den Platzierungstoleranzen des Leiterplattensteckers auf der Leiterplatte erfolgt nur eine schlechte oder überhaupt keine Kontaktie- rung zwischen Steckerschirmung des Leiterplattensteckers und dem I/O-Blech. Auch durch das Aufstecken eines Gegensteckers wird keine sichere Kontaktierung zwischen der Steckerschirmung des Leiterplattensteckers und dem I/O-Blech gewährleistet, da die Gegenstecker alle genormt sind und lediglich auf dem Leiterplattenstecker aufgesteckt und mit den Gewindebolzen verschraubt werden.Depending on the dimensional tolerances of the circuit board and the placement tolerances of the circuit board connector on the circuit board, there is poor or no contact between the connector shielding of the circuit board connector and the I / O plate. Even by attaching a mating connector, no reliable contact between the connector shield of the PCB connector and the I / O plate is guaranteed, since the mating connectors are all standardized and are only attached to the PCB connector and screwed to the threaded bolts.
Durch das Aufstecken der Gegenstecker besteht vielmehr die Gefahr, daß durch die Steckkraft der Leiterplattenstecker zu- rückgebogen wird und damit die sichere Kontaktierung zwischen der Steckerschirmung des Leiterplattensteckers und dem I/O- Blech verhindert wird. Auch wird durch das Aufstecken des Gegensteckers die Verbindung zwischen Leiterplattenstecker und Leiterplatte stark beansprucht, da die kompletten Steckkräfte auf diese Verbindung übertragen werden. Der neue Standard, gemäß welchem die Leiterplattenstecker mit den Gewindebolzen durch eine einzige Öffnung im I/O-Blech gesteckt werden, bringt zwar den Vorteil mit sich, daß die Gewindebolzen nicht mehr getrennt m den Leiterplattenstecker eingeschraubt werden müssen, jedoch geht die sichere Kontaktierung zwischen der Steckerschirmung des Leiterplattenstek- kers und des I/O-Bleches verloren und auf die Verbindung Leiterplattenstecker - Leiterplatte werden die Steckkrafte übertragen.Rather, by plugging in the mating connector, there is a risk that the plug-in force will bend the circuit board connector back and prevent the reliable contact between the connector shield of the circuit board connector and the I / O plate. The connection between the printed circuit board connector and the printed circuit board is also heavily stressed by the plugging in of the mating connector, since the complete plug-in forces are transmitted to this connection. The new standard, according to which the PCB connectors with the threaded bolts are inserted through a single opening in the I / O plate, has the advantage that the threaded bolts no longer have to be screwed into the PCB connector separately, but there is reliable contact the connector shield of the PCB connector and the I / O plate are lost and the connector forces are transferred to the PCB connector - PCB connection.
Der Erfindung liegt daher die Aufgabe zugrunde, die gattungsgemäße Steckverbindung nach dem neuen Standard derart weiter- zuentwickeln, daß ohne Verletzung des Standards eine sichere Kontaktierung zwischen der Steckerschirmung des Leiterplat- tensteckers und dem I/O-Blech erzielt wird.The invention is therefore based on the object of further developing the generic connector according to the new standard in such a way that a reliable contact between the connector shield of the printed circuit board connector and the I / O plate is achieved without violating the standard.
Diese Aufgabe wird erfmdungsgemaß dadurch gelöst, daß ein Stützmittel vorgesehen ist, das beim Verschrauben des Gegensteckers mit dem Leiterplattenstecker den Gegenstecker am I/O-Blech abstützt, und dadurch die Steckerschirmung am Leiterplattenstecker gegen das I/O-Blech zieht.This object is achieved according to the invention in that a supporting means is provided which supports the mating connector on the I / O plate when the mating connector is screwed to the circuit board connector, and thereby pulls the connector shield on the circuit board connector against the I / O panel.
Vorzugsweise sind wie beim Standard die Gewindebolzen am Leiterplattenstecker und die Schrauben am Gegenstecker angeord- net und die Gewindebolzen des Leiterplattensteckers durch die Öffnung im I/O-Blech gefuhrt. Der Leiterplattenstecker weist vorzugsweise eine sowohl flächige als auch kragenartige Stek- kerschirmung (Sub-D) m Form eines Schirmbleches oder eines metallisierten Kunststoffes auf, welche im m Steckrichtung vorspringenden Teil durch die Öffnung im I/O-Blech geführt ist .As with the standard, the threaded bolts are preferably arranged on the PCB connector and the screws on the mating connector, and the threaded bolts of the PCB connector are guided through the opening in the I / O plate. The circuit board connector preferably has a flat as well as a collar-like connector shield (Sub-D) in the form of a shield plate or a metallized plastic, which is led through the opening in the I / O plate in the part projecting in the plug direction.
Das Stützmittel kann zum Beispiel als Distanzstück ausgebildet sein, welches durch die auf das I/O-Blech durchgeführten Gewindebolzen aufsteckbar ist und sich im verschraubten Zustand auf der einen Seite am I/O-Blech und auf der anderen Seite am Gegenstecker abstützt. Das Distanzstück kann pro Gewindebolzen vorgesehen sein oder auch einteilig für beide Gewindebolzen ausgebildet sein, wobei bei dieser Ausführungsvariante dann eine Durchstecköff- nung für die Kontaktierung des Leiterplattensteckers und des Gegensteckers vorgesehen ist.The support means can be designed, for example, as a spacer, which can be attached by means of the threaded bolts passed through the I / O plate and is supported in the screwed state on the one side on the I / O plate and on the other side on the mating connector. The spacer can be provided per threaded bolt or can also be formed in one piece for both threaded bolts, with a through-opening being provided for the contacting of the circuit board connector and the mating connector in this embodiment variant.
Vorzugsweise ist das oder sind die Distanzstücke so ausgebildet, daß sie nach dem Aufstecken auf den Gewindebolzen selbst klemmend gehalten sind.Preferably, this or the spacers are designed so that they are held by clamping themselves after being attached to the threaded bolt.
Günstigerweise besteht das Distanzstück aus Kunststoff, kann jedoch auch zur zusätzlichen Kontaktierung aus einem leitfähigen Material wie Metall hergestellt sein.The spacer is advantageously made of plastic, but can also be made of a conductive material such as metal for additional contacting.
Gemäß einer alternativen Ausführungsform ist das Stützmittel mit dem I/O-Blech verbunden. Vorzugsweise ist es einstückig mit dem I/O-Blech ausgebildet und wird zum Beispiel durch Laschen, welche seitlich der Öffnung um 90° nach außen abgebo- gen sind, erzeugt.According to an alternative embodiment, the support means is connected to the I / O plate. It is preferably formed in one piece with the I / O plate and is produced, for example, by tabs which are bent outwards by 90 ° to the side of the opening.
Gemäß einer dritten Ausführungsform ist das Stützmittel an dem Gehäuse des Gegensteckers angeformt, so daß dieser stirnseitig nach der Verschraubung auf dem I/O-Blech aufliegt.According to a third embodiment, the support means is formed on the housing of the mating connector, so that it rests on the face of the I / O plate after the screw connection.
Nachfolgend wird die Erfindung anhand m den Zeichnungen dargestellter Ausführungsvarianten näher erläutert.The invention is explained in more detail below with reference to the embodiment variants shown in the drawings.

Figur 1 zeigt in der Schrägansicht ein I/O-Blech 1, welches bereits nach dem neuen Standard ausgebildet ist und durch welches von der Rückseite durch entsprechende Öffnungen 2 im I/O-Blech 1 Leiterplattenstecker 3 gesteckt sind. Die Leiterplattenstecker 3 weisen eine an der Rückseite des I/O Bleches 1 anliegende Frontfläche 4 sowie einen daran angeordneten in Steckrichtung weisenden Vorsprung 5 auf, welcher durch die Öffnung 2 im I/O-Blech 1 ragt.FIG. 1 shows an oblique view of an I / O plate 1, which is already designed according to the new standard and through which circuit board connectors 3 are inserted from the rear through corresponding openings 2 in the I / O plate 1. The circuit board connectors 3 have a front face 4 resting on the back of the I / O plate 1 and a projection 5 arranged thereon and pointing in the plugging direction, which protrudes through the opening 2 in the I / O plate 1.
Sowohl die Frontfläche 4 sowie der Vorsprung 5 der Leiterplattenstecker 3 sind mit einer Steckerschirmung 6 versehen, wobei die Steckerschirmung als Schirmblech oder durch metallisierten Kunststoff ausgebildet sein kann.Both the front surface 4 and the protrusion 5 of the printed circuit board connector 3 are provided with a connector shield 6, the connector shielding being able to be designed as a shield plate or through metallized plastic.
Diese Art von Stecker werden üblicherweise als Sub-D Stecker bezeichnet .This type of connector is commonly referred to as a Sub-D connector.
Auf der Frontfläche 4 des Leiterplattensteckers 3 sind fest mit dem Leiterplattenstecker 3 verbundene Gewindebolzen 7 angeordnet, welche ebenfalls von der Rückseite durch die Öffnung 2 des I/O-Bleches 1 geführt sind.On the front surface 4 of the circuit board connector 3 are firmly connected to the circuit board connector 3 threaded bolts 7, which are also guided from the rear through the opening 2 of the I / O plate 1.
Wird auf den Leiterplattenstecker 3 , wie er m Figur 1 m der unteren Position dargestellt ist, ist ein Gegenstecker aufgesteckt, so besteht die Gefahr, daß dieser nach hinten wegge- drückt wird und somit die Kontaktierung zwischen der Steckerschirmung 6 und dem I/O-Blech 1 unterbrochen wird.If a mating connector is plugged onto the printed circuit board connector 3, as shown in the lower position in FIG. 1, there is a risk that it will be is pressed and thus the contact between the connector shield 6 and the I / O plate 1 is interrupted.
Auch aufgrund von Maßungenauigkeiten der Leiterplatte, auf welchem der Leiterplattenstecker montiert ist, kann bereits von vornherein eine Beabstandung zwischen der Frontfläche 4 und der Rückseite des I/O-Bleches 1 vorliegen.Also due to dimensional inaccuracies of the printed circuit board on which the printed circuit board connector is mounted, there may already be a spacing between the front surface 4 and the rear side of the I / O plate 1 from the outset.
Die standardisierten Gegenstecker werden entweder m den kra- genartigen Vorsprung 5 eingesteckt oder mit ihrem Schirmblech über den Vorsprung 5 gesteckt und lediglich mit den Gewindebolzen 7 verschraubt.The standardized mating plugs are either inserted into the collar-like projection 5 or are plugged with their shielding plate over the projection 5 and only screwed to the threaded bolts 7.
Um bei der Verschraubung des Gegensteckers mit dem Leiter- plattenstecker 3 das I/O-Blech 1 gegen die Frontseite 4 des Leiterplattensteckers 3 zu pressen, ist wie beim oberen Leiterplattenstecker 3 dargestellt, ein Stützmittel m Form eines Distanzstückes 8 vorgesehen, welches auf die durch die Öffnung 2 des I/O-Bleches ragenden Gewindebolzen 7 aufge- steckt ist.In order to press the I / O plate 1 against the front side 4 of the circuit board connector 3 when the mating connector is screwed to the circuit board connector 3, a support means m in the form of a spacer 8 is provided, as shown for the upper circuit board connector 3 the opening 2 of the threaded bolt 7 projecting from the I / O plate is attached.
Gemäß diesem Ausführungsbeispiel ist das Distanzstuck 8 einteilig ausgebildet und weist eine Durchstecköffnung 9 für den kragenartigen Vorsprung 5 des Leiterplattensteckers 3 auf. Die Höhe des Distanzstuckes 8 ist so gewählt, daß bei einer Verschraubung des Gegensteckers mit dem Leiterplattenstecker 3 das I/O-Blech 1 gegen die Frontflache 4 des Leiterplattensteckers gepresst wird.According to this embodiment, the spacer 8 is formed in one piece and has a push-through opening 9 for the collar-like projection 5 of the circuit board connector 3. The height of the spacer 8 is chosen so that when the mating connector is screwed to the circuit board connector 3, the I / O plate 1 is pressed against the front surface 4 of the circuit board connector.
Figur 2 zeigt die Ansicht gemäß Figur 1, wobei als Stützmittel pro Gewindebolzen 7 jeweils ein Distanzstück 10 ausgebildet ist.FIG. 2 shows the view according to FIG. 1, a spacer 10 being formed as a supporting means for each threaded bolt 7.
In der Darstellung gemäß Figur 2 ist nur am oberen Leiter- plattenstecker 3 an einem Gewindebolzen 7 das Distanzstuck 10 aufgesteckt, wobei für die Steckverbindung auf beide Gewindebolzen 7 jeweils ein Distanzstück 10 aufgesteckt wird. Figur 3 zeigt ein I/O-Blech 1 mit drei Öffnungen 2 für Leiterplattenstecker 3 m Sub-D Form.In the illustration according to FIG. 2, the spacer 10 is plugged onto a threaded bolt 7 only on the upper printed circuit board connector 3, a spacer 10 being plugged onto the two threaded bolts 7 in each case. FIG. 3 shows an I / O plate 1 with three openings 2 for 3 m sub-D shape circuit board connectors.
