A clamp is conductively coupled to the plug connector, is spring actuated and secures the screened cable (6) to the connecting element. The plug connector is in the form of multi-plug connector (12a,b), plug-cable in two or more, adjacent or spaced conductor terminals of the module(s). The clamp is designed to secure several screened cables to the connecting element.

Description

Die Erfindung betrifft ein Anschlußelement zum Anschließen von Kabelschirmen von Schirmkabeln an Leiteranschlüsse wenigstens eines Moduls nach dem Oberbegriff des Anspruchs 1.The invention relates to a connection element for connecting cable shields of shield cables to conductor terminals of at least one module according to the preamble of claim 1.

Ein gattungsgemäßes Anschlusselement ist aus der EP-A-0 871 243 bekannt.A generic connection element is from the EP-A-0 871 243 known.

Ein weiteres Kabelschirm-Anschlußelement ist aus der DE 195 37 585 C1 bekannt. Das in dieser Schrift gezeigte Anschlußelement weist einen Stecker auf, welcher zum Einstecken in den Leiteranschluß einer PE-Klemme ausgelegt ist. An dem Stromleitstück ist ferner ein Klemmbügel gehalten und geführt und gegenüber einem abgewinkelten Steg des Stromleitstücks mittels einer Feder abgefedert. Der Klemmbügel hat eine unterhalb des abgewinkelten Stegs liegende Aufnahme für das Schirmkabel, das in der Aufnahme und unter dem Steg von der Feder festgeklemmt wird. Das Potential des angeschlossenen Kabelschirmes kann damit unmittelbar an den PE-Anschluß eines Reihenklemmenmoduls geführt werden.Another cable shield connection element is from the DE 195 37 585 C1 known. The connecting element shown in this document has a plug which is designed for insertion into the conductor terminal of a PE terminal. At the Stromleitstück a clamping bracket is also held and guided and cushioned against an angled web of Stromleitstücks by means of a spring. The clamp has a below the angled web lying receptacle for the shield cable, which is clamped in the receptacle and under the bridge of the spring. The potential of the connected cable shield can thus be performed directly to the PE terminal of a terminal module.

Das gattungsgemäße Kabelschirm-Anschlußelement hat sich zwar an sich bewährt. Beispielsweise für Module oder Reihenklemmen mit eng direkt nebeneinander liegenden Anschlüssen ist es jedoch wünschenswert, das gattungsgemäße Anschlußelement derart weiterzuentwickeln, daß ein unkomplizierteres Anschließen und Lösen von zwei oder mehr Schirmkabeln auf engem Raum möglich ist. Der Lösung dieser Aufgabe widmet sich die Erfindung.The generic cable shield connection element has proven itself in itself. For example, for modules or terminal blocks with closely juxtaposed terminals, it is desirable to further develop the generic connection element such that a more uncomplicated connection and disconnection of two or more shield cables in a small space is possible. The solution to this problem is devoted to the invention.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruches 1.The invention solves this problem by the subject matter of claim 1.

Da nicht für jedes Schirmkabel ein separates Anschlußelement notwendig ist, können mehrere Schirmkabel auf engem Raum an das Anschlußelement angeschlossen werden, ohne daß dabei die Nachteile einer relativ viel Raum benötigenden, separaten Sammelschiene in Kauf genommen werden müßten. Es können vielmehr direkt mit einem vorzugsweise steckerartigen Anschlußelement mehrere Anschlüsse kontaktiert werden. Die Erfindung eignet sich damit insbesondere für Module, die als reihenklemmenartige, scheibenförmige Elemente zum Aufrasten auf eine Tragschiene ausgebildet sind und für sich oder in Aneinanderreihung wenigstens zwei direkt nebeneinander liegende Leiteranschlüsse aufweisen. Darüber hinaus eignet sich die Erfindung aber auch für Modulblöcke oder Aneinanderreihungen von modulartigen Elementen wie Modulscheiben oder Reihenklemmen.Since a separate connection element is not necessary for each screen cable, a plurality of shielding cables can be connected in a tight space to the connection element, without the disadvantages of a relatively much space-requiring, separate busbar would have to be taken into account. Rather, several terminals can be contacted directly with a preferably plug-type connection element. The invention is thus particularly suitable for modules which are designed as a row clamp-like disk-shaped elements for latching onto a mounting rail and have at least two directly adjacent conductor terminals for themselves or in juxtaposition. In addition, the invention is also suitable for module blocks or juxtapositions of modular elements such as module disks or terminal blocks.

Der Rahmen mit den verschieblichen Klemmbügeln ermöglicht auf konstruktiv einfache Weise ein stabile Ausführung der Klemmeinrichtung auf engem Raum, insbesondere, da der Rahmen einen U-förmigen Querschnitt aufweist und die Klemmbügel in Schlitzen in den beiden zueinander parallelen Längsseiten des U-förmigen Rahmens geführt sind. Bei mehr als zwei Leitern ist es auch denkbar, die Klemmbügel in der Grundseite einer rahmenartigen Platte anzuordnen.The frame with the sliding clamps allows a structurally simple way a stable execution of the clamping device in a small space, in particular, since the frame has a U-shaped cross-section and the clamps are guided in slots in the two mutually parallel longitudinal sides of the U-shaped frame. With more than two conductors, it is also conceivable to arrange the clamp in the base of a frame-like plate.

Nach einer weiteren Variante der Erfindung sind die Rahmen im Bereich der Schlitze mit Abprägungen oder Einformungen versehen, welche Vorsprünge an den Klemmbügeln aufnehmen und führen. Die Vorsprünge und die sie berührenden Längsseiten der Rahmen als auch der Schlitze weisen vorzugsweise entsprechende Führungsgleitflächen auf. Die Klemmbügel stehen hiermit gar nicht oder aber nur besonders gering über die Außenkanten des Rahmens vor, was die Breite und damit den Raumbedarf der Anordnung verringert.According to a further variant of the invention, the frames are provided in the region of the slots with embossments or indentations, which receive and guide projections on the clamping brackets. The projections and the contacting longitudinal sides of the frame and the slots preferably have corresponding guide sliding surfaces. The clamps are hereby not or only very low on the outer edges of the frame, which reduces the width and thus the space requirements of the arrangement.

Nach einer Variante der Erfindung wird das Einführen der Leiter dadurch erleichtert, daß die Klemmbügel in einer geöffneten Stellung zum Einführen des Schirmkabels am Rahmen verrastbar sind. Hierzu eignet sich z.B. ein Vorsprung hinter Schlitzverbreiterungen zum Einsetzen der Klemmbügel.According to a variant of the invention, the introduction of the conductor is facilitated by the fact that the clamps can be latched in an open position for insertion of the shielding cable to the frame. For this purpose, for example, a projection behind Schlitzverbreiterungen for inserting the clamp is suitable.

Die Erfindung eignet sich neben den scheibenartigen Modulen auch für andere Arten von Modulen wie Modulblöcke oder für aneinandergereihte Module oder reihenklemmenartige Module (bzw. Reihenklemmen) und kann auch für mehr als zwei direkt nebeneinander liegende Leiteranschlüsse ausgelegt sein. Denkbar ist z.B. eine Art kammartige Ausbildung, z.B. um an ganz bestimmte, vorgegebene (z.B. den ersten, den dritten usw.) Leiteranschlüsse eines Modulblockes sammelschienenfunktionsähnlich einen Kabelschirm anzuschließen. Auch für die Modulblöcke mit vielen nebeneinander liegenden Leiteranschlüssen eignen sich aber die im Rahmen der Figurenbeschreibung erläuterten, ganz besonders vorteilhaften Anschlußelemente mit einem Doppelsteckeranschluß und zwei Klemmbügeln.The invention is in addition to the disc-like modules for other types of modules such as module blocks or for juxtaposed modules or series terminal-like modules (or terminal blocks) and can also be designed for more than two directly adjacent conductor connections. It is conceivable, e.g. a kind of comb-like formation, e.g. to connect a cable shield to a specific, predetermined (e.g., first, third, etc.) conductor terminals of a module block similar to a busbar function. Also for the module blocks with many juxtaposed wire connections but are explained in the context of the figure description, very particularly advantageous connection elements with a double connector and two clamps.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung unter Bezug auf die Zeichnung näher beschrieben. Es zeigt:

Hereinafter, an embodiment of the invention will be described with reference to the drawings. It shows:
Fig. 1
a first embodiment of a connecting element according to the invention;
Fig. 2
one for the connection element Fig. 1 suitable electrical module,

A second embodiment of a connecting element according to the invention.

Fig. 1 zeigt ein Anschlußelement 2 zum Anschließen von Kabelschirmen 4 von Schirmkabeln 6 an Leiteranschlüsse 8a, b (siehe Fig. 2) eines scheibenartigen elektrischen Moduls 10 zum Aufrasten auf eine (hier nicht dargestellte) Tragschiene.
Von diesen Leiteranschlüssen 8 erfolgt z. B. die Erdung der Kabelschirme 4 über Stromschienen und ggf. weitere (hier ebenfalls nicht abgebildete) Komponenten des Moduls 10. Fig. 1 shows a connecting element 2 for connecting cable shields 4 of shielding cables 6 to conductor terminals 8a, b (see Fig. 2 ) of a disc-like electrical module 10 for latching on a (not shown here) mounting rail.
From these conductor terminals 8 z. B. the grounding of the cable shields 4 via busbars and possibly other (also not shown here) components of the module 10th

Das Anschlußelement 2 weist zwei direkt nebeneinander liegende, abgeflachte und stiftartige - vorzugsweise mit Sollabknickstellen 13 versehene - Steckeranschlüsse 12a, b auf, welche an die Grundseite 14c eines in der Draufsicht U-förmigen Rahmens 14 angeformt und dazu ausgelegt sind, direkt in die Leiteranschlüsse 8a, b des Moduls 10 eingeführt zu werden. Die Sollabknickstellen 13 sind insbesondere für "kammartige" (hier nicht abgebildete) Ausführungen mit einer Vielzahl von Steckeranschlüssen 12 sinnvoll, da hierdurch nicht benötigte Steckeranschlüsse 12 einfach durch Abknikken entfernbar sind.The connecting element 2 has two directly adjacent, flattened and pin-like - preferably provided with Sollabknickstellen 13 - plug connections 12a, b, which are integrally formed on the base side 14c of a U-shaped frame 14 and designed to directly into the conductor terminals 8a , b of the module 10 to be introduced. The Sollabknickstellen 13 are particularly useful for "comb-like" (not shown here) versions with a variety of connector terminals 12, as this unneeded connector terminals 12 are simply removed by Abknikken.

Die Steckeranschlüsse bzw. -stifte 12 sind direkt an die Grundseite 14c des U-förmigen Rahmens 14 über eine stufenartige Biegung 15 angeformt. Die Steckerstifte 12 liegen damit leicht versetzt zur Grundseite 14c zu dieser parallel, so daß die Schraubendreheröffnungen aller Leiteranschlüsse 8 des Moduls 10 trotz aufgesetzter Anschlußvorrichtung 2 frei zugänglich bleiben.The plug terminals or pins 12 are formed directly on the base side 14 c of the U-shaped frame 14 via a step-like bend 15. The plug pins 12 are thus slightly offset from the base side 14c to this parallel, so that the screwdriver openings of all conductor terminals 8 of the module 10 remain freely accessible despite attached terminal device 2.

Der Rahmen 14 ist an den beiden Längsseiten 14b, 14c mit Schlitzen 16a, b versehen, in welchen Klemmbügel 18a, 18b verschieblich geführt sind, welche hier beispielhaft mit Schraubenfedern 20a, 20b an einem senkrecht zu den Wandungen des u-förmigen Rahmens 14 an diesen innen angeformten Steg 22 abgestützt sind. Alternativ sind auch Blattfedern denkbar. Die Federn 20 liegen an der von den Steckeranschlüssen 12 abgewandten Seite des Steges 22 zwischen dem Steg 22 und einem oberen Schenkel 24 der Klemmbügel 18 derart, daß sie beim Herunterdrücken der Klemmbügel 18 zusammengedrückt und damit gespannt werden. Von den oberen Schenkeln 24 aus durchsetzt ein Steg 26 der Klemmbügel die Schlitze 16, welcher außerhalb der Schlitze 16 parallel zu den Längsseiten 14a, b des Rahmens 14 nach unten gebogen ist. Seitliche Vorsprünge 28 des Stegs 26 sichern die Klemmbügel 18 in den Schlitzen 16 und führen diese an den Außenwandungen der Längsseiten 14a, b des Rahmens 14. Schlitzverbreiterungen 29 mit einer Formgebung entsprechend zu den Vorsprüngen 28 ermöglichen die einfache Montage der Klemmbügel 18 durch seitliches Einsetzen der Klemmbügel 18 in der unteren Position, durch ein sich daran anschließendes Hochschieben der Klemmbügel 18 in den Schlitzen 16 und ein sich daran anschließendes Einlegen der Federn 20.The frame 14 is provided on both longitudinal sides 14b, 14c with slots 16a, b, in which clamping brackets 18a, 18b are displaceably guided, which here by way of example with coil springs 20a, 20b on a perpendicular to the walls of the U-shaped frame 14 to this internally molded web 22 are supported. Alternatively, leaf springs are conceivable. The springs 20 are located on the side facing away from the plug terminals 12 side of the web 22 between the web 22 and an upper leg 24 of the clamping bracket 18 such that they are compressed upon depression of the clamping bracket 18 and thus clamped. From the upper legs 24 of a web 26 of the clamp passes through the slots 16 which is bent outside of the slots 16 parallel to the longitudinal sides 14a, b of the frame 14 downwards. Lateral projections 28 of the web 26 secure the clamping brackets 18 in the slots 16 and guide them on the outer walls of the longitudinal sides 14a, b of the frame 14. Slot widenings 29 with a shape corresponding to the projections 28th allow easy mounting of the clamp 18 by laterally inserting the clamp 18 in the lower position, by a subsequent pushing up of the clamp 18 in the slots 16 and then inserting the springs 20th

Unterhalb des Rahmensteges 22 sind die Stege 26 der Klemmbügel nach innen abgebogen und durchsetzen erneut die Schlitze 16 des Rahmens 14 nach innen. Die Stege 26 münden hier in Aufnahmen 30 für die Schirmkabel 6 bzw. deren Kabelschirme 4.Below the frame web 22, the webs 26 of the clamp are bent inwards and again enforce the slots 16 of the frame 14 inwards. The webs 26 open here in receptacles 30 for the shielding cable 6 and their cable screens 4th

Unterhalb des Steges 22 befinden sich die zueinander hin offenen Aufnahmen 30 und eine Aussparung 32 in der Rück- bzw. Grundseite 14c des Rahmens, welche derart bemessen ist, daß es problemlos möglich ist, die Schirmkabel 6 in der Aussparung 32 zu bewegen und seitlich sowie in der Höhe zu verschieben. Dies erleichtert das Einführen der Schirmkabel und der Kabelschirm(geflechte) 4 in die Aufnahmen 30.Below the web 22 are the mutually open receptacles 30 and a recess 32 in the rear or base side 14c of the frame, which is dimensioned such that it is easily possible to move the shielding cable 6 in the recess 32 and laterally to move in height. This facilitates the insertion of the shield cables and the cable shield (braid) 4 in the receptacles 30th

Der Rahmen 14 ist ferner platzsparend vorteilhaft derart ausgebildet, daß die Mittellachsen der Schirmkabel 6 jeweils direkt über den zugehörigen Leiteranschlüssen 12 liegen.The frame 14 is also advantageously designed to save space so that the central axes of the shielding cable 6 are each directly over the associated conductor terminals 12.

Ein an die Unterseite des Rahmens 14 nach vorn oder hinten angeformter Stützlappen 36 und ein vorderer Stützsteg 38 stabilisieren das Anschlußelement 2auf dem Modul 10.A support tab 36 integrally formed on the underside of the frame 14 forwardly or rearwardly and a front support bar 38 stabilize the connector 2 on the module 10.

Eine Einkerbung 40 (beispielhaft am rechten Klemmbügel 18a) erleichtert das Ansetzen des Schraubendrehers zur Krafteinleitung in die Schraubenfeder 20.A notch 40 (for example on the right clamping bracket 18a) facilitates the attachment of the screwdriver for introducing force into the coil spring 20.

Eine Aussparung 42 (beispielhaft am linken Klemmbügel 18b) ermöglicht das Anbringen einer (nicht dargestellten) Kennzeichnung und/oder Beschriftung. Die Kennzeichnung könnte auch an jeder beliebigen sonstigen Stelle des Anschlußelementes ausgebildet werden, welche gut einsehbar ist (so z.B. an der Rückseite des Rahmens 14).A recess 42 (for example, on the left clamping bracket 18b) allows the attachment of a (not shown) marking and / or label. The marking could also be formed at any other point of the connection element, which is easy to see (such as on the back of the frame 14).

Nach Art der Fig. 1 ist der Rahmen 14 im wesentlich senkrecht zur Moduloberseite im Bereich der Leiteranschlüsse 12 des Moduls 10 ausgerichtet. Diese Anordnung ist besonders übersichtlich, platzsparend und stabil. Alternativ ist es aber auch denkbar, den Rahmen 14 im wesentlichen parallel zur Moduloberseite auszurichten. In diesem Fall sind die Steckeranschlüsse 12 senkrecht zu den Wandungen 14 des Rahmens 14 angeformt, also parallel zum Steg 22, wobei das Schirmkabel nicht von vorn sondern von unten zugeführt wird.By type Fig. 1 the frame 14 is aligned substantially perpendicular to the module top in the region of the conductor terminals 12 of the module 10. This arrangement is very clear, space-saving and stable. Alternatively, it is also conceivable to align the frame 14 substantially parallel to the module top. In this case, the connector terminals 12 are formed perpendicular to the walls 14 of the frame 14, ie parallel to the web 22, wherein the shield cable is not supplied from the front but from below.

Die Funktion dieses Anschlußelementes 2 ist wie folgt:The function of this connection element 2 is as follows:

Zum Anschließen der Schirmkabel 6 wird das Anschlußelement 2 mit seinen Stekkeranschlüssen 12 direkt in die Leiteranschlüsse 8a, b des elektrischen Moduls 10 gesteckt. Die Stiftebenen liegen dabei beispielsweise parallel zu den sie kontaktierenden Stromschienen und Angriffsflächen der Anschlußelemente (hier nicht erkennbar). Der Stützlappen 36 und der Stützsteg 38 stabilisieren das Anschlußelement auf der Moduloberseite.To connect the shielding cable 6, the connecting element 2 is plugged with its Stekkeranschlüssen 12 directly into the conductor terminals 8a, b of the electrical module 10. The pen levels are, for example, parallel to the them contacting busbars and attack surfaces of the connecting elements (not visible here). The support tabs 36 and the support bar 38 stabilize the connection element on the module top.

Durch Herunterdrücken der Klemmbügel 18 mit einem Schraubendreher entsteht ein Aussparung zwischen der Unterseite des Steges 22 und einer der Aufnahmen 30 a,b, in welche nunmehr das erste Schirmkabel 6 einsetzbar ist, welches nach dem Lösen des Schraubendrehers zwischen der jeweiligen Aufnahme 30 und dem Steg 22 festgeklemmt wird. Der Anschluß des zweiten Schirmkabels 6 erfolgt problemlos in analoger Weise, wobei es das Einführen des Schirmkabels 6 nochmals entscheidend erleichtert, daß die Aufnahmen 30 zueinander hin offen ausgebildet sind und die Aussparung 32 genügend Platz zum Bewegen der i.allg. mit einem sperrigen Schinngeflecht versehenen Schirmkabel 6 bietet.By pressing down the clamp 18 with a screwdriver creates a recess between the bottom of the web 22 and one of the receptacles 30 a, b, in which now the first shielding cable 6 is inserted, which after loosening the screwdriver between the respective receptacle 30 and the web 22 is clamped. The connection of the second shielding cable 6 takes place without any problems in an analogous manner, whereby the insertion of the shielding cable 6 again makes it considerably easier for the receptacles 30 to be open towards each other and for the recess 32 enough space to move the i.allg. provides with a bulky Schinngeflecht provided shielding cable 6.

Zusammengefaßt bietet die Ausführung nach Fig. 1 ein konstruktiv einfaches, kostengünstiges Anschlußelement 2, welches auf engem Raum das Anschließen mehrerer Schirmkabel 6 bei einfachster Handhabung erlaubt.In summary, the execution offers Fig. 1 a structurally simple, inexpensive connection element 2, which allows a small space connecting several shielding cable 6 with ease of use.

Das Ausführungsbeispiel der Fig. 3 unterscheidet sich von dem Ausführungsbeispiel der Figur 1 im wesentlichen dadurch, daß die Steckeranschlüsse/-Stifte 12a, 12b um 90° umgebogen wurden, so daß es möglich ist, das Schirmkabel 6 mit dem Kabelschirm 4 senkrecht von unten an das Anschlußelement 2 heranzuführen. Die eigentliche Mechanik des Anschlußelementes 2 kann im wesentlichen analog zur Mechanik des Anschlußelementes der Fig. 1 ausgeführt werden. Der Rahmen 14 ist somit im wesentlichen parallel zur Moduloberseite im Bereich der Leiteranschlüsse 8 des Moduls 10 ausgerichtet.The embodiment of Fig. 3 differs from the embodiment of FIG. 1 essentially in that the plug connections / pins 12a, 12b have been bent by 90 °, so that it is possible to bring the shielding cable 6 with the cable shield 4 vertically from below to the connection element 2. The actual mechanics of the connecting element 2 can essentially analogous to the mechanics of the connecting element of Fig. 1 be executed. The frame 14 is thus aligned substantially parallel to the module top in the region of the conductor terminals 8 of the module 10.
