Description

Beschreibungdescription

Die Erfindung betrifft eine Blockiervorrichtung gegen Fehlsteckungen von Tochterleiterplatten auf einer Mutterleiterplatte, insbesondere, wenn mehrere Tochterleiterplatten zu einer Steckeinheit zusammengefasst sind und auf der Mutterleiterplatte mindestens zwei Leiterplattensteckverbinder kontaktieren.The invention relates to a blocking device against misinsertion of daughter boards on a motherboard, in particular, when a plurality of daughter boards are combined to form a plug-in unit and contact on the motherboard at least two PCB connectors.

Eine derartige Vorrichtung wird benötigt, um zu verhindern, dass auf einer Mutterleiterplatte, die mit einer großen Anzahl von gleichartigen Leiterplattensteckverbindern besetzt ist, eine oder mehrere Tochterleiterplatten die wiederum zu einer Steckeinheit zusammengefasst sind, nicht in Bereiche auf der Mutterleiterplatte gesteckt wird, die für diese Konfiguration nicht vorgesehen sind und dabei eventuell Systemausfälle verursachen.Such a device is needed to prevent one or more daughter boards, which in turn are assembled into a plug-in unit on a mother board occupied by a large number of similar board connectors, from being plugged into areas on the mother board that are for them Configuration are not provided and thereby possibly cause system failure.

Stand der TechnikState of the art

Bei umfangreichen Backplanesystemen - also großen Mutterleiterplatten - mit gleichartigen Leiterplattensteckverbindern, die einem MicroTCA-System zugeordnet sind, können zwei verschiedene Arten von Modulsteckverbindern gesteckt werden. Das eine System ist unter dem Namen "Advanced Mezzanine Card" (AMCs) bekannt, während eine weiteres unter "Mezzanines with Auxiliary Connections" (Multitongue-AMCs) bekannt ist, das auch MicroTCA-Carrier-Hub-Module aufnimmt (MCH).With extensive backplane systems - ie large motherboards - with similar PCB connectors, which are assigned to a MicroTCA system, two different types of module connectors can be plugged. One system is known as the Advanced Mezzanine Card (AMCs), while another is known as Mezzanines with Auxiliary Connections (Multitongue AMCs), which also includes MicroTCA Carrier Hub Modules (MCH).

Die Multitongue-AMC - Module sind Kartenrandsteckverbinder mit angefügten Leiterplatten, bei denen auf der Leiterkarte eine derartig große Anzahl von Signalkontakten vorgesehen ist, so dass zur Weiterleitung der Signale mindestens zwei separate Steckbereiche auf der Mutterleiterplatte notwendig sind.The multitongue AMC modules are card edge connectors with attached printed circuit boards, in which on the circuit board such a large number of signal contacts is provided, so that for forwarding the signals at least two separate plug-in areas on the motherboard are necessary.

Werden darüber hinaus zwei Tochterleiterplatten zusammengefasst, so können drei oder vier Steckbereiche erforderlich sein, die über eine gleiche Anzahl von Leiterplattensteckverbindern ihre Signale auf die Backplane übertragen.In addition, when two daughterboards are combined, three or four mating areas may be required to transmit their signals to the backplane via an equal number of printed circuit board connectors.

Dabei können die zusammengefassten Tochterleiterplatten als Kartenrandstecker über deren Leiterbahnenenden direkt gesteckt werden oder mittels eines so genannten Mehrfach-Leiterplatten-Steckaufsatzes in die Leiterplattensteckverbinder auf der Mutterleiterplatte gesteckt werden.In this case, the combined daughter boards can be plugged as a card edge connector on their conductor ends directly or plugged by means of a so-called multi-board plug-in attachment in the PCB connectors on the motherboard.

Dieser Mehrfach-Leiterplatten-Steckaufsatz wird separat gefertigt, mit den Leiterplatten verbunden und kontaktiert die Leiterplattensteckverbinder auf der Backplane.This multi-board connector is manufactured separately, connected to the circuit boards and contacts the PCB connectors on the backplane.

Da die Leiterplattensteckverbinder auf der Mutterleiterplatte für die AMCs und die Multitongue-AMCs jedoch die gleichen sind, aber eine unterschiedliche Kontaktbelegung aufweisen, muss sichergestellt werden, dass Fehlsteckungen bzw. Steckungen in nicht zulässigen Leiterplattensteckerbereichen vermieden werden.However, because the PCB connectors on the motherboard are the same for the AMCs and the multitongue AMCs, but have different pinouts, it must be ensured that pinouts in non-permissible PCB connector areas are avoided.

US 3,533,045 zeigt eine Blockiervorrichtung gemäß dem Oberbegriff von Anspruch 1. US 3,533,045 shows a blocking device according to the preamble of claim 1.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, dass eine aus mehreren Tochterleiterplatten bestehende Steckeinheit nicht in Bereiche auf der Mutterleiterplatte steckbar sind, die für diese Steckeinheit nicht vorgesehen sind.The invention is therefore based on the object that a plug-in unit consisting of several daughter boards are not pluggable into areas on the motherboard that are not provided for this plug-in unit.

Diese Aufgabe wird dadurch gelöst, dass zwischen zwei in einem regulären Steckabstand angeordneten Leiterplattensteckverbindern ein Blockierblock eingefügt ist, dass an dem Blockierblock Rastlaschen vorgesehen sind, dass die Leiterplattensteckverbinder auf ihren Längsseiten fensterartige Ausnehmungen aufweisen, in denen die Rastlaschen des Blockierblockes einrasten, wobei der Blockierblock eine Steckung der als Steckeinheit zusammengefassten Tochterleiterplatten auf der Mutterleiterplatte verhindert.This object is achieved in that between two arranged in a regular spacing PCB connectors a blocking block is inserted, that locking tabs are provided on the blocking block that the PCB connectors on their longitudinal sides have window-like recesses in which engage the locking tabs of the blocking block, the blocking block a Plugging the summarized as plug-in daughter circuit boards on the mother board prevented.

Eine vorteilhafte Ausgestaltung der Erfindung ist in den Ansprüchen 2-6 angegeben.An advantageous embodiment of the invention is specified in the claims 2-6.

Für die Übertragung einer großen Anzahl von Signalen von einer oder mehrerer Tochterleiterplatten steckbar auf eine Mutterleiterplatte, sind prinzipiell zwei Kontaktierungsmöglichkeiten vorgegeben, einmal eine direkte Steckung der Leiterbahnenden der Tochterleiterplatte in einen Leiterplattensteckverbinder auf der Mutterleiterplatte, und eine Steckung unter Inanspruchnahme eines zusätzlichen Steckverbinders, der mit der Tochterleiterplatte fest verbunden ist und dann in den Leiterplattensteckverbinder gesteckt wird.For the transmission of a large number of signals from one or more daughter boards pluggable on a motherboard, two Kontaktierungsmöglichkeiten are given in principle, once a direct insertion of the conductor ends of the daughterboard into a PCB connector on the motherboard, and a plug using an additional connector that with the daughter board is firmly connected and then plugged into the PCB connector.

Wenn die Anzahl der nebeneinander oder in Sandwichkarten übereinander angeordneten Signalkontakte nicht mehr von einem Steckverbinder übertragen werden kann, wird ein Verbund mehrerer gestaffelter Steckverbinder, hier als Mehrfach-Leiterplatten-Steckaufsatz bezeichnet, genutzt.If the number of side by side or in sandwich cards stacked signal contacts can no longer be transmitted from a connector, a combination of several staggered connector, referred to here as a multi-circuit board connector, used.

Da bei vielen Anwendungsfällen auf größeren Mutterleiterplatten auch gleichartige Leiterplattensteckverbinder eine unterschiedliche Kontaktbelegung aufweisen, besteht die Gefahr, dass Tochterleiterplatten an einem falschen Steckplatz gesteckt, zu kompletten Systemausfällen führen können.Since in many applications on larger motherboards and similar PCB connectors have a different pin assignment, there is a risk that daughter boards plugged into a wrong slot, can lead to complete system failure.

Zu einer Blockierung derartiger Steckbereiche ist vorgesehen, in die Zwischenräume des regulären Steckabstandes der Leiterplattensteckverbinder, ein Blockierelement einzufügen, das eine Fehlsteckung der Tochterleiterplatten-Steckeinheit verhindert.To block such plug-in areas is provided in the interstices of the regular plug-in distance of the PCB connectors to insert a blocking element, which prevents mis-mating of the daughter board plug-in unit.

Dazu sind vorteilhafterweise die Leiterplattensteckverbinder auf der Backplane oder Mutterleiterplatte an ihren Längsseiten mit fensterartigen Ausnehmungen versehen, die durch Längsrippen und diese kreuzende Querrippen gebildet werden.For this purpose, the printed circuit board connectors on the backplane or motherboard plate are advantageously provided on their longitudinal sides with window-like recesses, which are formed by longitudinal ribs and these crossing transverse ribs.

Weiterhin weisen die vorgesehenen Blockierelemente vorteilhafterweise flexible Rastlaschen auf, die beim Einfügen zwischen zwei Leiterplattensteckverbindern an den Längsrippen verrasten und damit ein Stecken der Steckeinheit mit den verhindern.Furthermore, the blocking elements provided advantageously have flexible locking tabs which latch when inserted between two PCB connectors to the longitudinal ribs and thus prevent plugging the plug-in unit with the.

Vorsehbar sind dabei unterschiedliche Größen für die Kodierblöcke, die auch zwischen unterschiedlich voneinander entfernten angeordneten Leiterplattensteckverbinder einfügbar sind.Predictable are different sizes for the coding blocks, which are also inserted between differently spaced apart PCB connectors.

Die Fig. 1. zeigt eine Seitenansicht eines Leiterplattensteckverbinders 3 auf seine Längsseite, wobei hier vier fensterartige Ausnehmungen 4 erkennbar sind.The Fig. 1 , shows a side view of a printed circuit board connector 3 on its longitudinal side, in which case four window-like recesses 4 can be seen.

Die fensterartigen Ausnehmungen 4 sind als Vertiefungen ausgebildet, die durch mehrere senkrechte Querrippen 6 und sie kreuzende waagrechte Längsrippen 5 geformt sind.The window-like recesses 4 are formed as depressions, which are formed by a plurality of vertical transverse ribs 6 and they crossing horizontal longitudinal ribs 5.

In den Fig. 2a, 2b ist ein erfindungsgemäßer Blockierblock dargestellt.In the Fig. 2a, 2b an inventive blocking block is shown.

Dabei zeigt die Fig. 2a eine isometrische Darstellung und die Fig. 2b eine Draufsicht des Blockierblockes.It shows the Fig. 2a an isometric representation and the Fig. 2b a plan view of the blocking block.

Der Blockierblock 10 weist eine quaderförmige Grundform auf und ist als Hohlkörper ausgeführt. Beidseitig seiner Längsseiten 11 sind jeweils zwei nach außen abstehende, dreiseitig freistehende Rastlaschen 15 ausgebildet, die durch eine mittige Strebe 13 getrennt sind.The blocking block 10 has a cuboidal basic shape and is designed as a hollow body. On both sides of its longitudinal sides 11 each two outwardly projecting, three-sided freestanding locking tabs 15 are formed, which are separated by a central strut 13.

Weiterhin ist an jeder der Rastlaschen 15, beidseitig der mittigen Strebe 13, eine teilweise keilförmige Ausnehmung 16 vorgesehen.Furthermore, a partially wedge-shaped recess 16 is provided on each of the locking tabs 15, on both sides of the central strut 13.

In diesem Bereich ist die mittige Strebe 13 um eine Stufe 14 gegenüber dem übrigen Niveau der Längsseite 11 zurückgenommen.In this area, the central strut 13 is withdrawn by a step 14 relative to the remaining level of the longitudinal side 11.

Weiterhin sind an den vier Eckseiten Vorsprünge 17 angeformt, die beim Einfügen eines Blockierblockes zwischen zwei Leiterplattensteckverbinder 3 oberhalb der waagrechten Längsrippen 5 positioniert bleiben, während die Rastlaschen 15 unterhalb der Längsrippen 5 in einer der fensterartigen Ausnehmungen 4 verrasten. (Siehe dazu auch Fig. 3)Furthermore, projections 17 are integrally formed on the four corner sides, which remain positioned when inserting a blocking block between two PCB connectors 3 above the horizontal longitudinal ribs 5, while the locking tabs 15 engage below the longitudinal ribs 5 in one of the window-like recesses 4. (See also Fig. 3 )

Um einen verrasteten Blockierblock wieder entfernen zu können, ist ein Teil der beiden an die mittige Strebe 13 angrenzenden Rastlaschen 15 keilförmig ausgenommen. Da die mittige Strebe 13 hier zurückgenommen ist, entsteht ein Steckschlitz18, in den ein entsprechendes Werkzeug, z. B. die Spitze eines Schraubendrehers, bis zu der Stufe 14 eingesetzt werden kann, so dass jeweils zwei benachbarte Rastlaschen 15 zurückgebogen und der Blockierblock entfernt werden kann.In order to be able to remove a latched blocking block again, part of the two locking lugs 15 adjoining the central strut 13 are wedge-shaped. Since the central strut 13 is withdrawn here, a Steckschlitz18, in which a corresponding tool, for. B. the tip of a screwdriver, can be used up to the level 14, so that each two adjacent locking tabs 15 bent back and the blocking block can be removed.

Die Fig. 3 zeigt eine Draufsicht auf mehrere parallel angeordnete Leiterplattensteckverbinder 3 zwischen denen jeweils ein Blockierblock 10 eingesetzt wurde. Dabei ist es prinzipiell unerheblich, an welcher der vier möglichen fensterartigen Ausnehmungen ein Blockierblock 10 eingesetzt wird, um die Steckung einer bestimmten Steckkartenversion zu unterbinden.The Fig. 3 shows a plan view of a plurality of parallel PCB connectors 3 between each of which a blocking block 10 has been used. It is in principle irrelevant, at which of the four possible window-like recesses, a blocking block 10 is used to prevent the insertion of a particular plug-in card version.

In der Fig. 4 sind in einer Schnittansicht mehrere der aus der Fig. 3 nebeneinander beabstandete und auf einer Mutterleiterplatte 1 angeordnete Leiterplattensteckverbinder 3 dargestellt, wobei zwischen den Steckverbindern Blockierblöcke 10 eingefügt sind.In the Fig. 4 are in a sectional view of several of the Fig. 3 side by side spaced and arranged on a motherboard 1 printed circuit board connector 3 is shown, wherein between the connectors blocking blocks 10 are inserted.

Dabei ist deutlich erkennbar, wie die Enden der Rastlaschen 15 an den waagrechten Längsrippen 5 verrastet sind.It can be clearly seen how the ends of the locking tabs 15 are latched to the horizontal longitudinal ribs 5.

Hieraus wird ersichtlich, wie ein eingefügter Blockierblock 10 die Steckung eine mehrere Tochterleiterplatten umfassende Steckeinheit 20 wirksam verhindert.It can be seen how an inserted blocking block 10, the plug effectively prevents a multiple daughter boards plug-in unit 20.

Wobei die Tochterleiterplatten 2 zur direkten Steckung als Kartenrandstecker ausgeführt sein können oder in einem Mehrfach-Leiterplatten-Steckaufsatz 20 zusammengeführt sind.Wherein the daughter boards 2 can be designed for direct connection as a card edge connector or combined in a multi-board plug-in attachment 20.

Eine einzelne Tochterleiterplatte kann hier natürlich problemlos gesteckt werden.Of course, a single daughter board can be easily plugged here.

Mittels der in den Leiterplattensteckverbindern 3 eingeformten Fenster 4 und mindestens einem Blockierblock 10 ist jedoch auch eine Kodierung einer Steckeinheit 20 möglich, wie dies in der Fig. 5 dargestellt ist.However, by means of the molded-in PCB connectors 3 window 4 and at least one blocking block 10 is also a coding of a plug-in unit 20 is possible, as shown in the Fig. 5 is shown.

Dabei sind bei der hier gezeigten Steckeinheit 20 drei Tochterleiterplatten 2 zusammengefasst, die für eine direkte Steckung in die Leiterplattensteckverbinder 3 vorgesehen sind, wobei die mittlere Tochterleiterplatte eine Ausnehmung 24 aufweist.In this case, in the plug-in unit 20 shown here, three daughter boards 2 are combined, which are provided for direct plugging into the printed circuit board connectors 3, the middle daughter board having a recess 24.

Auf der skizzierten Mutterleiterplatte 1 sind zwei Leiterplattensteckverbinder 3 und ein zwischen diesen verrasteter Blockierblock 10 angeordnet.On the sketched motherboard 1, two printed circuit board connectors 3 and a blocking block 10 latched between them are arranged.

Diese Steckeinheit kann problemlos gesteckt werden, da der Blockierblock 10 exakt in die Ausnehmung 24 der mittleren Tochterleiterplatte hineinpasst. Dabei ist bei dieser Steckeinheit sichergestellt, dass die mittlere Tochterleiterplatte ihre Signale über die beiden begrenzenden Leiterplatten weiterleitet.This plug-in unit can be inserted easily, since the blocking block 10 fits exactly into the recess 24 of the middle daughter board. It is ensured in this plug-in unit that the middle daughter board forwards their signals through the two limiting circuit boards.

Somit kann nur diese eine Steckeinheit gesteckt werden - trotz der eigentlich blockierenden Aufgabe des Blockierblockes, die gegeben wäre, wenn die mittlere Tochterleiterplatte keine Ausnehmung aufweisen würde.Thus, only this one plug-in unit can be plugged - despite the actually blocking task of the blocking block, which would be given if the middle daughter board would have no recess.
