Description

Die Erfindung betrifft eine Stromschiene mit Buchsen-Steckverbinder, insbesondere für Reihenklemmen, Klemmverbinder und dergleichen. In der modernen Verbindungstechnik werden zunehmend Reihenklemmen, Klemmverbinder und dergleichen eingesetzt, bei denen die Stromschienen neben einem Anschluß für einen ankommenden Leiter für den abgehenden Leiter einen Buchsen-Steckverbinder aufweisen, oder aber die Stromschienen zwischen einem Anschluß für einen ankommenden Leiter und einem Anschluß für einen abgehenden Leiter zwecks weiterer Potentialverteilung noch einen Buchsen-Steckverbinder aufweisen (DE 295 14 711 U1).The invention relates to a busbar with socket connector, in particular for terminal blocks, clamp connectors and the like. In modern connection technology Terminal blocks, clamp connectors and the like are increasingly used used where the busbars next to a connection for an incoming Conductors for the outgoing conductor have a socket connector, or the busbars between a connection for an incoming Conductor and a connection for an outgoing conductor for the purpose of further potential distribution still have a socket connector (DE 295 14 711 U1).

Da aus zwingenden elektrotechnischen Gründen die Dicke der Stromschiene nicht zu klein werden darf und beispielsweise in zahlreichen Anwendungsfällen 0,6 mm beträgt, andererseits aber bislang sowohl aus elektrischen wie aus federungstechnischen Gründen die tulpenförmigen Buchsen-Steckverbinder Materialstärken in der Größenordnung von nur 0,3 mm haben, hat man bislang derartige Buchsen-Steckverbinder an die Stromschienen angeschweißt. Eine solche Herstellungsweise ist teuer und darüberhinaus bezüglich der galvanischen Oberflächenbehandlung derartiger Bauteile problematisch. As the thickness of the busbar does not increase due to compelling electrical engineering reasons may become small and, for example, 0.6 mm in numerous applications on the other hand, but so far from both electrical and suspension technology Establish the tulip-shaped female connector material thicknesses in the Sizing connectors of the order of magnitude of only 0.3 mm welded to the conductor rails. Such a method of manufacture is expensive and moreover with regard to the galvanic surface treatment of such Components problematic.

Es ist andererseits grundsätzlich bei der Herstellung derartiger Buchsen-Steckverbinder als solcher bekannt (DE 32 24 933 C2), diese aus einem Bandmaterialzuschnitt in der passenden gewünschten Stärke dadurch herzustellen, daß der Bandmaterialzuschnitt mittig geschlitzt wird und durch einen weiteren seitlichen Schlitz in dem Zuschnitt zwei nebeneinanderliegenden Kontaktfedern unterschiedlicher Länge gebildet werden, wobei die längere Kontaktfeder die kürzere mit einer ihre spätere Kontaktzone bildenden Abwinkelung übergreift. Während dann bei der Bildung des Buchsen-Steckverbinders die kürzere Kontaktfeder im wesentlichen in der Zuschnittebene verbleibt, wird die längere Kontaktfeder aus der Zuschnittebene abgewinkelt und dann vor die kürzere Kontaktfeder gebogen. Als sehr problematisch für die Steckverbindung hat sich dabei allerdings erwiesen, daß die beiden zusammenwirkenden Kontaktfedern in ihrer Kontaktzone unterschiedliche Federcharakteristiken haben, da die längere Kontaktfeder weicher ist als die kürzere. Problematisch ist bei der dortigen Ausgestaltung auch, daß der eingesteckte Kontaktstitt die kürzere Kontaktfeder nur mit halber Breite kontaktieren kann.On the other hand, it is fundamentally involved in the manufacture of such socket connectors known as such (DE 32 24 933 C2), this from a band material blank to produce in the appropriate desired thickness by cutting the strip material is slit in the middle and through another side slit in the cut two adjacent contact springs of different lengths are formed, the longer contact spring the shorter with one of their later Angle forming contact zone overlaps. Then during the formation of the Socket connector the shorter contact spring essentially in the cutting plane remains, the longer contact spring is angled out of the cutting plane and then bent in front of the shorter contact spring. Being very problematic for however, the connector has proven that the two interact Contact springs in their contact zone have different spring characteristics because the longer contact spring is softer than the shorter one. Is problematic with the design there also that the inserted contact step the shorter contact spring can only contact half width.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Stromschiene mit Buchsen-Steckverbinder zu schaffen, die einfach und preisgünstig unter Gewährleistung einer einwandfreien Kontaktkraft herzustellen ist.The present invention has for its object a busbar with socket connector to create the simple and inexpensive guarantee a perfect contact force is to be established.

Die erfindungsgemäße Lösung ergibt sich im wesentlichen aus dem Patentanspruch 1. Dadurch, daß die Stromschiene und der Buchsen-Steckverbinder einstückig aus einem Bandmaterialzuschnitt gebildet sind, ist die Herstellung im Verhältnis zu dem Erfordernis des Anschweißens eines tulpenförmigen Buchsen-Steckverbinders an die Stromschiene erheblich vereinfacht. Da Ausgangsmaterial naturgemäß das Bandmaterial für die Stromschiene zu sein hat, wären normalerweise aufgrund der damit verbundenen Materialstärke die Kontaktfedern des Buchsen-Steckverbinders zu steif. Das wird erfindungsgemäß dadurch ausgeglichen, daß man Kontaktfedern relativ lang macht und sie dadurch wieder weicher macht. Da normalerweise in den meisten Anwendungsfällen allerdings die ansich dafür erforderliche Baulänge oberhalb der Stromschiene gar nicht zur Verfügung steht, ist durch die erfindungsgemäße Ausgestaltung dafür Sorge getragen, daß ein Teil der gewünschten Federlänge in der Ebene der Stromschiene verbleibt, hier hat man im Normalfall Platz genug, den trennenden Schlitz im Bandmaterialzuschnitt und damit die Länge der Kontaktfedern insgesamt zweckentsprechend wählen zu können.The solution according to the invention results essentially from the patent claim 1. In that the busbar and the socket connector from one piece a band material blank is formed, the production is in relation to that Requirement of welding a tulip-shaped socket connector to the Track greatly simplified. Since the raw material is naturally the strip material would have to be for the power rail, would normally be because of that connected material thickness, the contact springs of the socket connector are too stiff. This is compensated according to the invention in that contact springs are relatively long and thereby softening them again. Because usually in most Use cases, however, the overall length required for this above the Busbar is not available at all, is due to the configuration according to the invention made sure that part of the desired spring length in the The level of the conductor rail remains, here you normally have enough space to separate the one Slit in the strip material cut and thus the total length of the contact springs to be able to choose appropriately.

Da die längere der beiden Kontaktfedern weicher ist als die kürzere, wird zur Vermeidung unterschiedlicher Kontaktkräfte der beiden zusammenwirkenden Kontaktfeder in ihrer Kontaktzone das wiederum dadurch ausgeglichen, daß man die längere Kontaktfeder breiter als die kürzere ausbildet. Obwohl somit die beiden Kontaktfedern des Buchsen-Steckverbinders aus dem relativ dicken Stromschienenmaterial bestehen, haben sie in ihrer Kontaktzone die gewünschten Kontaktkräfte sowohl der Größe nach wie auch der Gleichmäßigkeit nach von Kontaktfeder zu Kontaktfeder.Since the longer of the two contact springs is softer than the shorter one, this is avoided different contact forces of the two interacting contact spring in their contact zone this in turn compensated for by the fact that the longer Contact spring is wider than the shorter one. Although the two contact springs the socket connector consist of the relatively thick conductor rail material, Do you have the desired contact forces in your contact zone? Size as well as uniformity from contact spring to contact spring.

Weitere bevorzugte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet. Hervorzuheben ist in dem Zusammenhang eine weitere zusätzliche Ausgleichsmaßnahme für die weichere Kontaktfeder im Bereich ihrer Anlenkung an die Stromschiene im übrigen, beispielsweise in Form einer Versteifungssicke.Further preferred configurations are characterized in the subclaims. In this context, another additional compensatory measure should be emphasized for the softer contact spring in the area of its linkage to the conductor rail otherwise, for example in the form of a stiffening bead.

Hervorzuheben ist ferner eine besondere Schnittführung im Zuschnitt derart, daß sich in ihrer Kontaktzone eine Verbreiterung für die kürzere Kontaktfeder ergibt, damit der Kontaktstift nach Einsteckung auch an ihr in voller Breite anlegen kann.Also to be emphasized is a special cut in the cut such that results in a widening for the shorter contact spring in their contact zone, so that the After insertion, the contact pin can also be applied to it in its full width.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel ist eine Stromschiene 1 vorgesehen, die an ihrem einen Ende ein abgewinkeltes Anschlußstück 2 aufweist, auf das beispielsweise zwecks Anschließen eines ankommenden Leiters eine Zugfeder 3 aufgesetzt sein kann. In the exemplary embodiment shown in FIG. 1, a busbar 1 is provided, which has an angled connector 2 at one end to which a tension spring 3, for example, for connecting an incoming conductor can be put on.

Die Stromschiene 1 ist einstückig mit einem Buchsen-Steckverbinder 4 ausgebildet, der der Potentialweiterleitung mittels eines einzusteckenden Kontaktstiftes dient. Eine derartige Stromschiene mit Buchsen-Steckverbinder kann beispielsweise in dem Isolierstoffgehäuse einer Reihenklemme angeordnet werden.The busbar 1 is formed in one piece with a socket connector 4, which is used to transmit the potential by means of a contact pin to be inserted. A Such busbar with socket connector can, for example, in the insulating housing a terminal block can be arranged.

Derartige Stromschienen haben aus elektrotechnischen Gründen normalerweise Dicken in der Größenordnung von etwa 0,6 mm. Diese Materialstärke wäre grundsätzlich für die Ausbildung des Buchsen-Steckverbinders zu groß, da die dann daraus gebildeten Kontaktfedern zu steif wären. Um trotzdem derartige Kontaktfedern 5, 6 für den Buchsen-Steckverbinder 4 einstückig am Bandmaterialzuschnitt 1a der Stromschiene 1 ausbilden zu können, wird der Bandmaterialzuschnitt 1a (s. Figur 2) mit einem relativ langen Längsschlitz 7 und einem davon abgehenden an der Seite mündenden Querschlitz 8 derart versehen, daß zunächst in diesem Bandmaterialzuschnitt 1a eine längere Kontaktfeder 5 sowie eine kürzere Kontaktfeder 6 gebildet werden, dergestalt, daß die längere Kontaktfeder 5 mit einer Abwinkelung 5', die später ihre Kontaktzone bildet, das Stirnende der kürzeren Kontaktfeder 6 übergreift. Die beiden Kontaktfedern 5, 6 werden dann so aus der Stromschienenebene zueinander hochgebogen, daß, wie insbesondere der Vergleich der Figuren 1 und 2 zeigt, ein Teil der Federlängen der Kontaktfedern 5, 6 in der Ebene der Stromschiene 1 verbleibt, die gesamte wirksame Federlänge der Kontaktfedern sich also aus einem kleinen, noch geschlitzten Bereich in der Ebene der Stromschiene 1, den sich daran anschließenden Krümmungsradien sowie der sich dann ergebenden Restlänge der Kontaktfedern 5, 6 ergibt. Dank dieser Ausgestaltung kann man bei entsprechender Wahl der Länge des Längsschlitzes 7 die Kontaktfedern 5, 6 trotz der relativ großen Materialdicke infolge einer erheblichen Federlänge so weich gestalten, daß sich die gewünschte Kontaktkraft für den Buchsen-Steckverbinder 4 ergibt, ohne daß dadurch die Bauhöhe des Buchsen-Steckverbinders 4, also dasjenige Maß, um das er sich über die Ebene der Stromschiene 1 erstreckt, zu groß wird.Such busbars usually have electrical engineering reasons Thicknesses on the order of about 0.6 mm. This material thickness would be basic Too big for the formation of the socket connector, because then contact springs formed from it would be too stiff. To contact springs of this kind 5, 6 for the socket connector 4 in one piece on the strip material blank 1a To be able to form the busbar 1, the strip material blank 1a (see FIG 2) with a relatively long longitudinal slot 7 and an outgoing thereof on the side opening transverse slot 8 so that initially in this band material blank 1a, a longer contact spring 5 and a shorter contact spring 6 are formed be such that the longer contact spring 5 with a bend 5 ', the later forms their contact zone, overlaps the front end of the shorter contact spring 6. The two contact springs 5, 6 are then mutually from the busbar level bent up, that, as the comparison of FIGS. 1 and 2 in particular shows, a part of the spring lengths of the contact springs 5, 6 in the plane of the busbar 1 remains, the total effective spring length of the contact springs thus from one small, still slotted area in the plane of the busbar 1, which is attached to it subsequent radii of curvature and the resulting remaining length of the Contact springs 5, 6 results. Thanks to this design, you can with appropriate Choice of the length of the longitudinal slot 7, the contact springs 5, 6 despite the relatively large Make the material thickness so soft due to the considerable length of the spring that the Desired contact force for the socket connector 4 results without the height of the socket connector 4, that is the amount by which it is extends over the level of the busbar 1, is too large.

Die längere Kontaktfeder 5 ist aufgrund eben ihrer größeren Länge weicher als die kürzere Kontaktfeder 6. Dies würde zu ungleichmäßigen Federkräften und Federwegen für die Kontaktfedern 5, 6 in ihrer gemeinsamen Kontaktzone führen. Um dies auszugleichen, wird die Anordnung im Bandmaterialzuschnitt 1a so getroffen, daß die längere und damit weichere Kontaktfeder 5 zumindest bei einem nicht unbeträchtlichen Teil ihrer Längserstreckung, ausgehend vom Anlenkpunkt an der Stromschiene 1 im übrigen, breiter und damit von der Federcharakteristik her härter als die kürzere Kontaktfeder 6 ausgebildet wird. The longer contact spring 5 is softer than that because of its greater length shorter contact spring 6. This would lead to uneven spring forces and spring travel lead for the contact springs 5, 6 in their common contact zone. To do this to compensate, the arrangement in the strip material cut 1a is made so that the longer and therefore softer contact spring 5, at least for one insignificant part of their longitudinal extent, starting from the articulation point on the Busbar 1 in the rest, wider and thus harder from the spring characteristic than the shorter contact spring 6 is formed.

Auf diese Weise läßt sich erreichen, daß trotz unterschiedlicher Federlängen die beiden Kontaktfedern 5, 6 in ihrer Kontaktzone gleiche Federkräfte bei gleichem Federweg haben.In this way it can be achieved that despite different spring lengths, the two Contact springs 5, 6 have the same spring forces in their contact zone with the same spring travel to have.

In den Figuren 1 und 2 ist eine weitere zusätzliche Ausgleichsmöglichkeit bezüglich Federkraft und Federweg der beiden unterschiedlich langen Kontaktfedern 5, 6 illustriert. So ist dort die längere und damit weichere Kontaktfeder 5 zusätzlich im Bereich ihrer Anlenkung an die Stromschiene im übrigen und damit in ihrem Anfangsbereich, der in der Ebene der Stromschiene 1 verbleibt, durch eine eingedrückte Sicke 9 zusätzlich versteift.In Figures 1 and 2 there is a further additional compensation option with regard to The spring force and spring travel of the two contact springs 5, 6 of different lengths are illustrated. So there is the longer and therefore softer contact spring 5 in addition Area of your articulation on the busbar in the rest and thus in your Initial area that remains in the plane of the busbar 1 by an indented Bead 9 additionally stiffened.

Wie sich aus Figur 2 ergibt, ist ferner der Längsschlitz 7 derart verschränkt zum Querschlitz 8 geführt, daß sich für das freie Ende der kürzeren Kontaktfeder 6, das deren Kontaktzone bildet, eine Verbreiterung ergibt. Auf diese Weise ist gewährleistet, daß beide Kontaktfeder 5 und 6 in ihrer Kontaktzone einen hier einzusteckenden Kontaktstift in dessen voller Breite kontaktieren können, wie insbesondere die Anschauung der Figur 3 zeigt.As can be seen from FIG. 2, the longitudinal slot 7 is also interlaced with Cross slot 8 out that for the free end of the shorter contact spring 6, the whose contact zone forms a widening. This ensures that both contact springs 5 and 6 in their contact zone one to be inserted here Can contact contact pin in its full width, in particular the View of Figure 3 shows.

Die Figur 3 zeigt im übrigen die Ausführungsform einer Stromschiene 1, bei der in den Anfangsbereich der längeren Kontaktfeder 5a keine Sicke eingeprägt ist. Hier besteht die Ausgleichsmaßnahme somit ausschließlich in der unterschiedlichen Breitengestaltung der Kontaktfedern 5a, 6.3 shows the rest of the embodiment of a busbar 1, in which no bead is impressed in the initial area of the longer contact spring 5a. Here the compensatory measure therefore consists solely in the different Width of the contact springs 5a, 6.

In den Figuren 4 und 5 ist ein weiteres Ausführungsbeispiel einer derartigen Stromschiene mit Buchsen-Steckverbinder illustriert. Hier ist eine Stromschiene 1b vorgesehen, die zwei Anschlußstücke 2 zum Anschließen eines ankommenden und eines abgehenden Leiters aufweist, was beispielsweise wiederum durch Zugfedern geschehen kann. Zur zusätzlichen Potentialverteilung hat diese Stromschiene 1b wiederum einen zusätzlichen Buchsen-Steckverbinder 4. Dieser Buchsen-Steckverbinder 4 ist an einem zunächst in der Ebene des Bandmateriales liegenden, später davon abgewinkelten Stromschienenzuschnittstück 1c genauso ausgebildet, wie vorstehend im Zusammenhang mit den Figuren 1 bis 3 näher beschrieben. Es sind somit auch hier wieder eine längere Kontaktfeder 5 und eine kürzere Kontaktfeder 6 vorgesehen, wobei die längere Kontaktfeder 5 breiter ist als die kürzere Kontaktfeder 6. Ggf. kann auch hier wieder als zusätzliche Versteifungsmaßnahme für die längere Kontaktfeder 5 eine Sicke vorgesehen sein. Auch hier kann durch die entsprechende Führung des Längsschlitzes 7 im Zuschnittabschnitt 1b dafür Sorge getragen werden, daß die Kontaktzone der kürzeren Kontaktfeder 6 verbreitert ist. FIGS. 4 and 5 show a further exemplary embodiment of such a busbar illustrated with female connector. Here a busbar 1b is provided, the two connectors 2 for connecting an incoming and one has outgoing conductor, which in turn by tension springs can happen. This busbar has 1b for additional potential distribution again an additional socket connector 4. This socket connector 4 is on a later lying in the plane of the strip material of which angled busbar blank 1c is formed in the same way as above described in connection with Figures 1 to 3 in more detail. There are thus here again a longer contact spring 5 and a shorter contact spring 6 provided, the longer contact spring 5 is wider than the shorter contact spring 6. If necessary can also be used as an additional stiffening measure for the longer one Contact spring 5 a bead may be provided. Again, through the appropriate Guidance of the longitudinal slot 7 in the cutting section 1b to ensure that the contact zone of the shorter contact spring 6 is widened.

Für alle vorstehend beschriebenen Ausführungsformen gilt, daß die Kontaktflächen in den Kontaktzonen der Kontaktfedern sich aus der Fläche des Bandmaterialzuschnittes ergeben und durch die Stanz- und Biegemaßnahmen nicht beeinflußt werden, so daß in denkbar einfacher Weise das Bandmaterial galvanisch fertig behandelt werden kann und damit insbesondere nicht etwa die insoweit verbiegungsgefährdeten Stanz-Biegeteile galvanisch behandelt bzw. zumindest galvanisch nachbehandelt werden müssen.For all the embodiments described above, the contact surfaces in the contact zones of the contact springs from the surface of the strip material blank result and are not influenced by the punching and bending measures, so that the strip material can be treated galvanically finished in a very simple manner can, and in particular not those who are prone to bending Stamped and bent parts are galvanically treated or at least galvanically aftertreated Need to become.
