Abstract

1. Coding device for component boards insertable into a component rack and provided with a multipoint connector (5), connecting elements (4, 7, 8) being located both on the horizontal subracks (1) and also on the individual components, characterized in that there are provided on the front upper and lower horizontal subracks (1) of the component rack between the guide rails (2) coding elements (3) for the components which have one or more slots (4) extending parallel to the guide rails (2), and in that webs (7, 8) corresponding to the slots (4) are attached as counter-coding elements to the upper and lower end faces of the multipoint connector (5).

Description

Die Erfindung betrifft eine Codiervorrichtung für in einen Baugruppenrahmen einschiebbare und mit einer Steckverbinderleiste versehene Baugruppen, wobei sich Codierelemente sowohl auf dem waagerechten Baugruppenträger als auch auf den einzelnen Baugruppen befinden.The invention relates to a coding device for modules which can be inserted into a module frame and which are provided with a connector strip, coding elements being located both on the horizontal module rack and on the individual modules.

Es ist bekannt, an die Steckverbinderleisten von einschiebbaren Baugruppen Codiedeisten anzubringen die mit in die Steckrichtung weisenden Vorsprüngen versehen sind. An die zugehörige Gegensteckeinrichtung wird eine Gegencodiedeiste angebracht, die mit zu den Vorsprüngen passenden Vertiefungen versehen ist Die Form der Anordnung der Vorsprünge bzw. Vertiefungen ist für verschiedene Baugruppen unterschiedlich. Auf diese Weise wird sichergestellt, daß die Baugruppen an der richtigen Stelle in den Baugruppenrahmen eingesetzt werden.It is known to attach code strips to the connector strips of insertable assemblies which are provided with projections pointing in the direction of insertion. A counter-code bar is attached to the associated mating connector, which is provided with depressions matching the projections. The shape of the arrangement of the projections or depressions is different for different assemblies. This ensures that the modules are inserted in the correct place in the module frame.

Nachteilig bei dieser Art der Codierung ist es, daß die einzelnen Codierungen erst wirksam werden, wenn die Baugruppe fast ganz eingeschoben ist, und so keine Sichtkontrolle mehr möglich ist ob die richtige Baugruppe gewählt worden ist.The disadvantage of this type of coding is that the individual codes only take effect when the module is almost completely inserted, and so it is no longer possible to visually check whether the correct module has been selected.

Hinzu kommt, daß die Baugruppen mit einer erheblichen Kraft in den Baugruppenrahmen eingeschoben werden, so daß die Codierung bei Zusammentreffen der Steckverbindung stark belastet werden und beschädigt werden können.In addition, the assemblies are pushed into the assembly frame with considerable force, so that the coding can be heavily loaded and damaged when the connector meets.

Aus der DE-A 2 362 060 ist eine Vorrichtung zum mechanischen Codieren eines Einschubplatzes für eine steckbare Flachbaugruppe in einem Baugruppenrahmen mit Hilfe einer Anordnung von zusammenwirkenden Codierstiften und Codierkammern, die an der dem Steckverbinder der Flachbaugruppe gegenüberliegenden Frontseite der Rachbaugruppe an einer Frontplatte und an einer vorderen Rahmenleiste des Baugruppenträgers angeordnet sind, bekannt. Durch die Anordnung der Codierelemente auf der dem Steckverbinder gegenüberliegenden Frontseite der Flachbaugruppen ist zwar bis kurz vor dem Ineinandergreifen der Codierelemente eine minimale Sichtkontrolle möglich, jedoch ist diese bekannte Vorrichtung für Steckverbindedeisten mit voreilenden Kontaktstiften nachteilig, da die voreilenden Kontaktstifte der Steckverbinderleiste bereits vor dem Zusammentreffen der Codierelemente auf die Messerleiste des Baugruppenrahmens treffen und beschädigt werden können.DE-A 2 362 060 describes a device for mechanically coding a slot for a plug-in flat module in a module frame with the aid of an arrangement of interacting coding pins and coding chambers, which are attached to a front plate and to one on the front side of the ratchet module opposite the plug connector of the flat module front frame of the subrack are arranged, known. Due to the arrangement of the coding elements on the front side of the printed circuit boards opposite the connector, a minimal visual inspection is possible until shortly before the interlocking of the coding elements, but this known device for connector strips with leading contact pins is disadvantageous, since the leading contact pins of the connector strip already before the meeting of the Encoding elements can hit the male connector of the module frame and can be damaged.

Aufgabe der vorliegenden Erfindung ist es, eine Codiervorrichtung der eingangs genannten Art anzugeben, bei der schon vor dem Einschieben der Baugruppe eine gute Sichtkontrolle möglich ist, ob die entsprechenden Codierelemente zusammenpassen, und die den problemlosen Einsatz von voreilenden Kontaktstiften ermöglicht.The object of the present invention is to provide a coding device of the type mentioned at the outset, in which a good visual check is possible even before the module is inserted, as to whether the corresponding coding elements fit together and which enables the problem-free use of leading contact pins.

Diese Aufgabe wird für eine Codiereinrichtung der obengenannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved for a coding device of the type mentioned above by the characterizing features of claim 1.

Die erfindungsgemäße Codiereinrichtung hat den Vorteil, daß die Codierung auf ihre Richtigkeit vom Benutzer sofort beim Einsetzen der Baugruppe erkennbar ist. Auf diese Weise wird eine mögliche Betätigung der Codierung vermieden. Nach dem Einschieben der Baugruppe wird die Codiervorrichtung mechanisch nicht mehr belastet.The coding device according to the invention has the advantage that the correctness of the coding can be recognized by the user immediately when the module is inserted. In this way, possible actuation of the coding is avoided. After the module has been inserted, the coding device is no longer mechanically loaded.

Eine andere Lösung der der Erfindung zugrundeliegenden Aufgabe ist durch die kennzeichnenden Merkmale des Anspruchs 2 gekennzeichnet.Another solution to the problem on which the invention is based is characterized by the characterizing features of claim 2.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Lösungen ergeben sich aus den Unteransprüchen wie aus der anschließenden Beschreibung zweier Ausführungsbeispiele.Advantageous refinements of the solutions according to the invention result from the subclaims and from the subsequent description of two exemplary embodiments.

Im folgenden wird die Erfindung anhand zweier in der Zeichnung dargestellte Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to two exemplary embodiments shown in the drawing.

Es zeigen

  • Fig. 1 verschiedene Ansichten einer Codiervorrichtung, bei der die Steckverbindedeiste mit Stegen versehen ist, und
  • Fig. 2 verschiedene Ansichten einer Codiervorrichtung, bei der die Steckverbinderleiste mit Schlitzen versehen ist.
Show it
  • Fig. 1 shows various views of a coding device in which the connector strip is provided with webs, and
  • Fig. 2 different views of a coding device, in which the connector strip is provided with slots.

Der obere Teil der Fig. 1 zeigt eine teilweise Vorderansicht zwei Baugruppen von der Steckseite her, der mittlere Teil eine Vorderansicht des Baugruppenträgers mit Führungsschienen und der untere Teil eine Draufsicht auf den Baugruppenträger mit den Führungsschienen. Der Baugruppenträger 1 ist Teil eines Baugruppenrahmens der in diesem Zusammenhang nicht näher dargestellt ist. An diesen Baugruppenträger 1 sind Führungsschienen 2 angebracht, in denen die Leiterplatten 6 der einschiebbaren Baugruppen geführt sind. Der Abstand der Führungsschienen 2 richtet sich nach der Art der Bestückung der einschiebbaren Baugruppen. Zwischen den Führungsschienen 2 sind beim dargestellten Ausführungsbeispiel Codierelemente 3 angebracht die im dargestellten Ausführungsbeispiel jeweils zwei Schlitze 4 aufweisen. Um eine Codierung zu ermöglichen sind an den Steckverbinderleisten 5 der Baugruppen Stege 7 und 8 angebracht, die den Schlitzen 4 entsprechen.The upper part of FIG. 1 shows a partial front view of two modules from the plug-in side, the middle part a front view of the module carrier with guide rails and the lower part a top view of the module carrier with the guide rails. The rack 1 is part of a module frame which is not shown in this context. On this rack 1 guide rails 2 are attached, in which the circuit boards 6 of the insertable modules are guided. The distance between the guide rails 2 depends on the type of assembly of the insertable modules. In the illustrated embodiment, coding elements 3 are attached between the guide rails 2, each of which has two slots 4 in the illustrated embodiment. In order to enable coding, webs 7 and 8, which correspond to the slots 4, are attached to the connector strips 5 of the assemblies.

Die Codierung erfolgt nun prinzipiell dadurch, daß entweder, wie dargestellt, an der Steckverbinderleiste 2 Stege, ein Steg an unterschiedlicher Stelle, oder kein Steg vorhanden ist. Entsprechend müssen die Schlitze des Codierelementes 3 durchgängig oder gesperrt sein. Ein Sperren der Schlitze 4 geschieht durch Riegel 9 und 10. Dabei können die Riegel für die Codierelemente 3 unterschiedlich ausgeführt sein. Es kann sich einmal um nachträglich herausbrechbare Kunststoffriegel 9 handeln oder aber um nachträglich einsetzbare Kunststoffriegel 10. Ebenso können zwei Ausführungsformen für die an den Steckverbinderleisten angebrachten Stege vorgesehen sein. Einmal kann es sich dabei um nachträglich einschiebbare Stege 7 oder um nachträglich abbrech- oder abschneidbare Stege 8 handeln.The coding now takes place in principle in that either 2 webs, a web at different locations, or no web is present on the connector strip, as shown. Accordingly, the slots of the coding element 3 must be continuous or blocked. The slots 4 are blocked by bolts 9 and 10. The bolts for the coding elements 3 can be designed differently. It can be a plastic bar 9 that can be subsequently broken out, or a plastic bar 10 that can be used later. Likewise, two embodiments can be provided for the webs attached to the connector strips. On the one hand, these can be webs 7 that can be subsequently inserted or webs 8 that can be subsequently broken off or cut off.

Die Umkehrung des in Fig. 1 dargestellten Codierungsprinzip ist in der Fig. 2 dargestellt. Bei dieser Ausführungsform besitzt das Codierelement 12 zwischen den Führungsschienen 2 Stege, während die Steckverbinderleiste 11 der Baugruppe mit Schlitzen 14 versehen ist. Auch bei dieser Lösungsmöglichkeit kann einer oder beide der Stege 13 entfernt werden bzw. können in die Schlitze 14 der Steckverbindedeiste 11 Riegel eingeschoben werden.The reversal of the coding principle shown in FIG. 1 is shown in FIG. 2. In this embodiment, the coding element 12 has 2 webs between the guide rails, while the connector strip 11 of the assembly is provided with slots 14. With this possible solution, one or both of the webs 13 can be removed be or can be inserted into the slots 14 of the connector strip 11 latch.

Aus den Figuren ist zu entnehmen, daß die Codierung der vorliegenden Erfindung sofort bei Einschieben der Baugruppe wirksam wird. Auf diese Weise ist eine falsche Codierung für den Benutzer sofort erkennbar. Dadurch wird eine mechanische Beschädigung der Codierung vermieden, da beim Einführen einer Baugruppe noch keine großen Kräfte aufgewendet werden, wie dies zum Schluß kurz vor Stecken der Baugruppe normaler Weise geschieht. Die erfindungsgemäße Codiervorrichtung besteht nur aus wenigen Teilen - nur einsetzbare, bzw. abbrechbare Stege und einsetzbare bzw. abbrechbare Riegel als Codiermittel - , und sie ist ohne große Vodeistung einfach nachrüstbar.It can be seen from the figures that the coding of the present invention takes effect immediately when the assembly is inserted. In this way, incorrect coding is immediately recognizable to the user. This avoids mechanical damage to the coding, since large forces are not yet expended when a module is inserted, as is normally the case shortly before the module is inserted. The coding device according to the invention consists of only a few parts - only insertable or breakable webs and insertable or breakable bars as coding means - and it can be easily retrofitted without a great deal of effort.
