Description

Die vorliegende Erfindung betrifft einen Halter für Sammelschienen. Derartige Sammelschienen sind beispielsweise bekannt aus der EP-B-0 751 585. Dort ist beschrieben, dass beispielsweise bei Reihenklemmenblöcken noch zusätzliche, dort als Stromschienen bezeichnete Sammelschienen eingesetzt werden können. Derartige Sammelschienen dienen zur Kontaktierung mit mehreren Kontakten. Insbesondere werden hierfür Schraubkontakte verwendet. Ein häufiger Anwendungsfall ist beispielsweise die selektive Brückung ausgewählter Reihenklemmen eines aus einer Vielzahl von Reihenklemmen zusammengesetzten Reihenklemmenblocks. Hierbei ist es unerwünscht, dass die Sammelschiene beispielsweise beim Anschrauben von Schraubkontakten ihre Stellung verändert, also verschoben wird. Der erfindungsmäßige Sammelschienenhalter dient folglich zur mechanischen Halterung bzw. Lagerung der Sammelschiene.The present invention relates to a holder for busbars. such Busbars are known for example from EP-B-0 751 585. There is described that, for example, in the case of terminal block blocks, additional, busbars referred to there as busbars can be used. Such busbars are used to make contact with several contacts. In particular screw contacts are used for this. A common use case is, for example, the selective bridging of selected terminal blocks a terminal block composed of a plurality of terminal blocks. It is undesirable that the busbar, for example when screwing on screw contacts their position changed, i.e. shifted becomes. The busbar holder according to the invention is therefore used for mechanical Bracket or storage of the busbar.

Nach dem Stand der Technik sind die bekannten Lagerungen für Sammelschienen kompliziert aufgebaut. Insbesondere ist es häufig erforderlich, die Sammelschiene mit Hilfe einer Schraubbefestigung oder wie im Falle der EP-B-0 751 585 durch nachträglich aufgebrachte bzw. angebrachte mechanische Haltemittel zu sichern.According to the prior art, the known bearings for busbars complicated structure. In particular, it is often necessary to use the busbar with the help of a screw fastening or as in the case of EP-B-0 751 585 through subsequently attached or attached mechanical holding means to back up.

Eine Sammelschiene, gemäß Oberbegriff des Anspruchs 1 ist auch aus DE-U-9 315 475 bekannt.A busbar, according to the preamble of the Claim 1 is also known from DE-U-9 315 475.

Der vorliegenden Erfindung liegt folglich die Aufgabe zugrunde, einen Halter für eine Sammelschiene möglichst einfach auszugestalten. Diese Aufgabe ist durch die Merkmalskombination des Anspruchs 1 gelöst. Die Unteransprüche enthalten teils zweckmäßige, teils für sich selbst erfinderische Weiterbildungen der Erfindung.The present invention is therefore based on the object of a holder for to make a busbar as simple as possible. This task is through solved the combination of features of claim 1. The sub-claims included partly useful, partly for themselves inventive developments of the invention.

Die Erfindung beruht auf der Überlegung, am Sammelschienenhalter eine zur Geometrie der Sammelschiene komplementär ausgestaltete Aufnahmenut vorzusehen. In den Nutquerschnitt dieser Aufnahmenut steht mindestens eine gegen ein Federelement widergelagerte Federbacke hinein. Dies hat den Vorteil, dass der erfindungsmäßige Sammelschienenhalter seinerseits als randseitiger Sammelschienenhalter verwendet werden kann. Hierbei steht die Federbacke in den Querschnitt der Aufnahmenut hinein und bildet für die Sammelschiene einen Anschlag und hebt somit die axiale Verschieblichkeit der Sammelschiene auf. Zum anderen ist es aber auch möglich, den erfindungsmäßigen Sammelschienenhalter bei längeren Sammelschienen als Zwischenhalter einzusetzen. Hierbei umschließt die Aufnahmenut die Sammelschiene formschlüssig. Allerdings wird bei dieser Verwendung die Federbacke einfach gegen den Federdruck aus dem Querschnitt der Aufnahmenut herausgedrückt, so dass die Federbacke nicht mehr störend in die Aufnahmenut hineinsteht. Die Aufnahmenut ist somit durchgehend zur Durchleitung der Sammelschiene freigelassen.The invention is based on the consideration of one on the busbar holder To provide the geometry of the busbar complementary receiving groove. At least one is in the groove cross section of this receiving groove a spring element placed in a spring jaw. This has the advantage that the busbar holder according to the invention, in turn, as an edge-side busbar holder can be used. Here, the spring jaw is in the Cross section of the receiving groove and forms a stop for the busbar and thus eliminates the axial displaceability of the busbar. To the but it is also possible for others to use the busbar holder according to the invention to be used as an intermediate holder for longer busbars. This encloses the receiving groove has a positive fit on the busbar. However, with this Simply use the spring jaw against the spring pressure from the cross section the receiving groove is pushed out so that the spring jaw is no longer a nuisance the receiving groove is in. The receiving groove is thus continuous Passing the busbar free.

Vorteilhaft ist die Ausgestaltung des Sammelschienenhalters nach Anspruch 2 mit einer Federbacke an jeweils einer der beiden Enden der Aufnahmenut. Hierdurch ist es möglich, ein und denselben Sammelschienenhalter einmal als Randbegrenzungshalter auf der rechten Seite der Sammelschiene und das andere Mal als Randbegrenzungshalter auf der linken Seite der Sammelschiene einzusetzen. Die jeweils nicht benötigte, also störende Federbacke wird hierbei einfach aus der Aufnahmenut herausgedrückt, während die andere, jeweils benötigte Federbacke als rechter bzw. linker Endanschlag für die Sammelschiene wirksam ist. Mit einem einzigen Sammelschienenhaltertyp ist es somit möglich, sowohl einen rechten Randbegrenzungshalter als auch einen linken Randbegrenzungshalter als auch einen zwischen die Randbegrenzungshalter zwischengeschalteten Zwischenhalter zu realisieren. Dies ist fertigungstechnisch einfach und minimiert darüber hinaus die erforderliche Lagerhaltung in vorteilhafter Weise.The configuration of the busbar holder according to claim 2 is advantageous a spring jaw on each of the two ends of the receiving groove. hereby it is possible to use one and the same busbar holder as an edge limitation holder on the right side of the busbar and the other time than Insert edge limitation bracket on the left side of the busbar. The each not needed, so annoying spring jaw is simply from the Pressing the receiving groove out while the other spring jaw is required acts as a right or left end stop for the busbar. With a single busbar type, it is therefore possible to use both a right-hand one Border holder as well as a left border holder as well an intermediate holder interposed between the edge limitation holders to realize. This is simple in terms of production technology and also minimizes the required storage in an advantageous manner.

Besonders vorteilhaft ist die Verwendung der in Anspruch 3 vorgeschlagenen U-Querschnittsform für die Aufnahmenut. Die Aufnahmenut ist dann nach Art eines Aufnahmemauls ausgestaltet, welches die im Querschnitt üblicherweise rechteckförmige Sammelschiene von drei Seiten her umschließt, was die Führungs- und Lagerungseigenschaften des Halters in vorteilhafter Weise begünstigt. Des Weiteren vorteilhaft ist es, die Federbacken im Bereich der vom U-Grund mit jeweils einem der beiden U-Schenkel gebildeten Zwickel anzuordnen. Auf diese Weise ist die Sammelschiene bereits formschlüssig und flächig in der Aufnahme geführt, bevor sie in Eingriff mit den Federbacken gerät. Es ist dann sehr leicht möglich, mit Hilfe der Sammelschiene eine im Wege stehende Federbacke aus dem Querschnitt der Aufnahmeöffnung in ihre Inaktivstellung auszurücken. Außerdem sind die so angeordneten Federbacken am Sammelschienenhalter gut geschützt angeordnet und sind vor Zerstörung gut gesichert.The use of the U cross-sectional shape proposed in claim 3 is particularly advantageous for the receiving groove. The receiving groove is then in the manner of a Designed receiving mouth, which is usually rectangular in cross section Busbar encloses from three sides, which the guide and storage properties of the holder favorably favored. Of It is also advantageous to have the spring jaws in the region of the U base to arrange one of the two U-legs formed gusset. To this The busbar is already form-fitting and flat in the receptacle performed before it comes into engagement with the spring jaws. Then it is very easy possible, with the help of the busbar a standing spring jaw to move the cross-section of the receiving opening into its inactive position. Moreover the spring jaws so arranged on the busbar holder are good arranged protected and are well secured against destruction.

Anspruch 4 lehrt eine in der Praxis häufig benötigte Anordnung der Aufnahmenut, nämlich zur Bestückung des Sammelschienenhalters von der Haltervorderseite her. Diese Anordnung ist durch die Lehre der Ansprüche 5 und 6 derart weitergebildet, dass die Federbacken sowohl von unten her in die Aufnahmenut hineinstehen als auch von oben her in die Aufnahmenut hineinhängen können. Ebenso ist es möglich, an einem Ende eine hängende und am anderen Ende eine stehende Federbacke vorzusehen. In weiterer Ausgestaltung ist es natürlich auch denkbar, jeweils paarweise eine stehende und eine hängende Federbacke an jedem Ende der Aufnahmenut vorzusehen.Claim 4 teaches an arrangement of the receiving groove that is frequently required in practice, namely for loading the busbar holder from the front of the holder forth. This arrangement is further developed by the teaching of claims 5 and 6, that the spring jaws both protrude from below into the receiving groove as well as hanging in the receiving groove from above. Likewise it is possible to have a hanging at one end and a standing at the other Provide spring jaw. In a further embodiment it is of course also conceivable a standing and a hanging spring jaw in pairs at each end to provide the receiving groove.

Um die Federbacken leichter aus ihrer in die Aufnahmenut hineinstehenden Aktivstellung in ihre die Aufnahmenut freigebende Inaktivstellung verfahren zu können, ist nach Anspruch 7 vorgesehen, die Schmalseiten der Federbacken mit Auflaufschrägen zu versehen bzw. sie zur Bildung von Auflaufschrägen einfach abzuschrägen. Auf diese Weise bilden die Flächen der Auflaufschrägen Bahnführungen für die auflaufenden Kanten der Sammelschienen, so dass die Sammelschienenkante einfach durch weiteres Eindrücken der Sammelschiene in die Aufnahmenut die jeweils nicht benötigte Federbacke bzw. Federbacken in ihre Inaktivstellung verfährt.To lighten the spring jaws from their active position in the receiving groove to be able to move into their inactive position which releases the receiving groove, is provided according to claim 7, the narrow sides of the spring jaws with bevels to be provided or simply beveled them to form run-up slopes. In this way, the surfaces of the run-up slopes form web guides for the leading edges of the busbars, so that the busbar edge simply by pushing the busbar further into the slot the spring jaw or spring jaws not required in their inactive position moves.

Besonders vorteilhaft ist es den Sammelschienenhalter aus Kunststoff zu spritzen. Kunststoffspritztechnisch wiederum einfach ist es, die Federbacken einfach an Federarme anzuspritzen, welche wiederum mit dem Gehäuse verbunden sind. It is particularly advantageous to inject the plastic busbar holder. Plastic injection molding, in turn, is easy, the spring jaws simply on Injection molded spring arms, which in turn are connected to the housing.

Zur Sicherung der Sammelschiene in ihrer Montageendstellung im Sammelschienenhalter ist nach den Ansprüchen 9 und 10 vorgeschlagen, einen schwenkbaren Haltevorsprung der Aufnahmenut vorzulagern. In den Haltevorsprung ist vorteilhaft eine Tasche eingeformt zur Aufnahme einer Schrauberklinge. Mit Hilfe der Schrauberklinge ist es einfach möglich, den Haltevorsprung zu manipulieren, insbesondere die Aufnahmenut zum Ein- oder Ausschieben der Sammelschiene zu öffnen.To secure the busbar in its final assembly position in the busbar holder is proposed according to claims 9 and 10, a pivotable To hold the projection of the receiving groove. In the holding projection is advantageous a pocket molded to hold a screwdriver blade. With the help of Screwdriver blade, it is easily possible to manipulate the holding projection, in particular the receiving groove for inserting or removing the busbar to open.

Die U-Schenkel 7,8 sind verbunden durch den die Nutrückseite bildenden U-Grund 9. Dem U-Grund 9 in Einschubrichtung 10 der Sammelschiene 6 gegenüber liegt die Nutöffnung 11. Insbesondere in der Darstellung der Fig. 2 gut erkennbar ist die Tatsache, dass die Aufnahmenut 5 nach Art eines Aufnahmemauls für die Sammelschiene 6 in die Vorderseite 4 des Sammelschienenhalters 1 eingeformt ist.The busbar holder 1 has 2 locking elements 3 on its underside Fixation on a mounting rail, not shown in the drawings. In the Front 4 of the busbar holder 1 is molded into the U-shaped receiving groove 5. In the receiving groove 5 there is a busbar 6. The receiving groove 5 is designed to be U-shaped. The receiving groove 5 is lying in this way arranged that you form a U-leg 7 the bottom of the receiving groove, while the second U-leg 8 forms the top of the groove. The U-legs 7.8 are connected by the U-bottom 9 forming the back of the groove. The U-bottom 9 The slot opening 11 lies opposite in the insertion direction 10 of the busbar 6. The fact that. Can be seen particularly well in the illustration in FIG. 2 the receiving groove 5 in the manner of a receiving mouth for the busbar 6 in the front 4 of the busbar holder 1 is molded.

In Fig. 2 des Weiteren erkennbar ist der der Aufnahmenut 5 in Einschubrichtung 10 der Sammelschiene 6 vorgelagerte Haltevorsprung 12. Der Haltevorsprung 12 ragt in der zur Einschubrichtung 10 senkrecht verlaufenden Sperrrichtung 13 in die Aufnahmenut 5 hinein. Entlang der Sperrrichtung 13 verläuft auch die Vorderseite 4 des Sammelschienenhalters 1 von der Unterseite 2 her zur Oberseite 14.FIG. 2 also shows that the receiving groove 5 in the direction of insertion 10 of the busbar 6 upstream holding projection 12. The holding projection 12 protrudes in the blocking direction 13 running perpendicular to the insertion direction 10 in the receiving groove 5 into it. The front also runs along the blocking direction 13 4 of the busbar holder 1 from the bottom 2 to the top 14.

Zum Einführen der Sammelschiene 6 in die Aufnahmenut 5 wird die in Fig. 2 dargestellte Schraubendreherklinge 15 in die in den Haltevorsprung 12 eingeformte Aufnahmetasche 16 eingeführt. Mit Hilfe der Schrauberklinge 15 wird der Haltevorsprung 12 in Sperrrichtung 13 in Richtung auf die Unterseite 2 des Sammelschienenhalters 1 nach unten gedrückt, bis der Vorsprunglagerarm 17 am Wegbegrenzungsvorsprung 18 anschlägt. So dann wird die Sammelschiene 6 in Einschubrichtung 10 in die dann freigegebene Aufnahmenut 5 eingeschoben. Zur Fixierung der Sammelschiene 6 in der sowohl zur Sperrrichtung 13 als auch zur Einschubrichtung 10 jeweils senkrecht verlaufenden Axialrichtung 19 der Sammelschiene 6 steht in die Aufnahmenut 5 die Federbacke 20 in Sperrrichtung 13 hinein.To insert the busbar 6 into the receiving groove 5, the one shown in FIG. 2 is shown Screwdriver blade 15 molded into the retaining projection 12 Recording pocket 16 introduced. With the help of the screwdriver blade 15 is the holding projection 12 in the blocking direction 13 towards the underside 2 of the busbar holder 1 pressed down until the projection bearing arm 17 on the travel limit projection 18 strikes. So then the busbar 6 in the direction of insertion 10 inserted into the then released receiving groove 5. to Fixing the busbar 6 in both the blocking direction 13 and Insertion direction 10 each perpendicular axial direction 19 of the busbar 6 is in the receiving groove 5, the spring jaw 20 in the blocking direction 13th into it.

An der Federbacke 20 ausgebildet ist die Auflaufschräge 21. Die Auflaufschräge 21 wird dann wirksam, wenn die Sammelschiene 6 die Aufnahmenut 5 in Axialrichtung 19 übergreift, also durch die Aufnahmenut 5 hindurchgeleitet wird. In diesem Fall gleitet die im Montageendzustand hintere untere Kante der Sammelschiene 6 auf der Auflaufschräge 21 hinauf und verfährt die Federbacke 20 in ihre Inaktivstellung. Hierfür ist unterhalb der Federbacke 20 ein Ausweichraum 22 in den Sammelschienenhalter 1 eingeformt.The run-up slope 21 is formed on the spring jaw 20. The run-up slope 21 becomes effective when the busbar 6 the receiving groove 5 in the axial direction 19 overlaps, ie is passed through the receiving groove 5. In this Fall slides the rear lower edge of the busbar in the final assembly state 6 on the ramp 21 and moves the spring jaw 20 in her Inactive. For this purpose there is an escape space 22 in below the spring jaw 20 molded the busbar holder 1.

Aus Fig. 1 ist ersichtlich, dass die Federbacke 20 die Verschieblichkeit der Sammelschiene 6 in Axialrichtung 19 aufhebt. Bezogen auf die Darstellung der Fig. 1 ist die Sammelschiene 6 folglich durch den Sammelschienenhalter 1 an ihrer linken Seite gegen Axialverschiebung gesichert. Fig. 3 zeigt einen analog zum Sammelschienenhalter 1 in Fig. 1 ausgebildeten Sammelschienenhalter 1'. Der Sammelschienenhalter 1' weist wiederum an seiner Unterseite 2 Rastelemente 3 zum Aufrasten auf eine in den Zeichnungen nicht dargestellte Tragschiene auf. Auch die übrigen im Zusammenhang mit Fig. 1 und Fig. 2 beschriebenen Teile sind bei dem in Fig. 3 dargestellten Sammelschienenhalter 1' identisch ausgestaltet, was durch die Vergabe derselben Bezugsziffern zum Ausdruck kommt.From Fig. 1 it can be seen that the spring jaw 20, the displaceability of the busbar 6 in the axial direction 19. Based on the representation of FIG. 1 is the busbar 6 consequently through the busbar holder 1 on its left Side secured against axial displacement. Fig. 3 shows an analog to Busbar holder 1 formed in Fig. 1 busbar holder 1 '. The Busbar holder 1 'in turn has 2 latching elements 3 on its underside for snapping onto a mounting rail, not shown in the drawings. The other parts described in connection with FIGS. 1 and 2 are identical in the busbar holder 1 'shown in FIG. 3, which is expressed by assigning the same reference numbers.

Während beim im Ausführungsbeispiel linken Sammelschienenhalter 1 gemäß Fig. 1 und Fig. 2 die Federbacke 20 in dem vom unteren, der Unterseite 2 des Sammelschienenhalters 1 näheren U-Schenkel 7 und vom U-Grund 9 gebildeten Zwickel angeordnet ist, also die Federbacke 20 dort von unten her in die Aufnahmenut 5 hineinsteht, ist die Federbacke 20' an dem in den Fig. 3 und 4 dargestellten Ausführungsbeispielen in dem vom oberen U-Schenkel 8 und dem U-Grund 9 gebildeten Zwickel angeordnet. In dem in Fig. 3 und Fig. 4 dargestellten Beispiel des rechts angeordneten Sammelschienenhalters 1' hängt die Federbakke 20' folglich von oben her in die Aufnahmenut 5 des Sammelschienenhalters 1' hinein. Es sei nochmals ausdrücklich erwähnt, dass auch an einem Sammelschienenhalter 1, 1' eine Paarung einer auf der einen Seite von der Unterseite her in die Aufnahmenut 5 hineinstehenden Federbacke 20 und auf der anderen Seite von oben her in die Aufnahmenut 5 hineinstehenden Federbacke 20' vorhanden sein kann. Diese Ausführungsform hat den Vorteil, dass die Federarme zur Lagerung der Federbacken 20, 20' besonders lang ausgestaltet sein können, so dass sie eine besonders gute Hebelwirkung haben.While in the case of the left busbar holder 1 in the exemplary embodiment according to Fig. 1 and Fig. 2, the spring jaw 20 in the from the lower, the bottom 2 of the Busbar holder 1 closer U-leg 7 and formed by the U-base 9 Gusset is arranged, that is, the spring jaw 20 there from below into the receiving groove 5 stands in, the spring jaw 20 'on that shown in FIGS. 3 and 4 Embodiments in that of the upper U-leg 8 and the U-bottom 9 formed gusset arranged. In the one shown in FIGS. 3 and 4 Example of the busbar holder 1 'arranged on the right hangs the spring claw 20 'consequently from above into the receiving groove 5 of the busbar holder 1' into it. It should be expressly mentioned again that also on a busbar holder 1, 1 'a pairing on one side from the bottom spring jaw 20 protruding into the receiving groove 5 and on the other side Spring jaw 20 'protruding into the receiving groove 5 from above can be. This embodiment has the advantage that the spring arms for storage of the spring jaws 20, 20 'can be made particularly long, so that they have a particularly good leverage effect.

In der Darstellung der Fig. 4 ist erkennbar, dass die gestrichelt dargestellte Sammelschiene 6 nach dem Herunterdrücken des Haltevorsprungs 12 mittels der Schraubendreherklinge 15 in Einschubrichtung 10 in die Aufnahmenut 5 eingeschoben werden kann. Hierbei wird die von oben, im Montageendzustand also rechts angeordnete Federbacke 20' in Sperrrichtung 13 in die Aufnahmenut 5 hineinstehen, um ihre Sperrwirkung in axialer Richtung 19 ausüben zu können. Mit ihrer hinteren Unterkante hingegen wird die Sammelschiene 6 die Auflaufschräge 21 der Federbacke 20 beaufschlagen und diese nach unten in ihren Ausweichraum 22 in ihre Inaktivstellung hineindrücken, so dass bei dem in Fig. 3 und Fig. 4 dargestellten Sammelschienenhalter 1' im Montageendzustand die rechte von oben her hängende Federbacke 20' in ihrer Aktivstellung die Axialverschieblichkeit der Sammelschiene 6 verhindert, während dies bei dem in Fig. 1 und Fig. 2 dargestellten Ausführungsbeispiel genau umgekehrt ist. Dort befindet sich die von unten her in die Aufnahmenut 5 hineinragende Federbacke 20 in ihrer Aktivstellung, während die von oben her in die Aufnahmenut 5 hineinragende Federbacke 20' in ihre Inaktivstellung verfahren ist.4 that the busbar shown in dashed lines can be seen 6 after pressing down the holding projection 12 by means of the Screwdriver blade 15 inserted into the receiving groove 5 in the insertion direction 10 can be. This is from above, in the final assembly state spring jaw 20 'arranged on the right protrude into the receiving groove 5 in the blocking direction 13, in order to be able to exert their locking action in the axial direction 19. With its rear lower edge, however, the busbar 6 is the ramp Actuate 21 of the spring jaw 20 and this down into its escape space 22 push into its inactive position, so that in the case of FIGS Fig. 4 shown busbar holder 1 'in the final assembly state the right spring jaw 20 'hanging from above in its active position the axial displaceability the busbar 6 prevented, while this in the in Fig. 1 and Fig. 2 shown embodiment is exactly the opposite. There is the spring jaw 20 projecting from below into the receiving groove 5 in its active position, while the spring jaw protruding from above into the receiving groove 5 20 'has moved to its inactive position.
