Abstract

A connector for clamping one or more electrical conductors has a shackle which cooperates with a screw serving to urge one end portion of a rail toward a bottom wall of the shackle. The bottom wall has a central portion flanked by two convergent lateral portions which guide one or more conductors against the internal surface of the central portion when the screw causes the end portion of the rail to approach the bottom wall. The underside of the end portion of the rail has a centrally located platform whose underside urges the conductor or conductors against the central portion of the bottom wall and which is assisted by two ridges disposed between pairs of recesses in the end portion of the rail. The lateral portions of the bottom wall have notches which receive portions of the platform, and the recesses receive portions of the corresponding lateral wall portions. The undersides of the ridges can constitute concave surfaces to further enhance the gathering, centering and clamping effect of the end portion of the rail when the screw is rotated in a direction to advance the end portion toward the inner side of the bottom wall.

Description

Die Erfindung betrifft eine Verbindungsklemme für elektrische Leiter entsprechend dem Gattungsbegriff des Anspruches 1.The invention relates to a connecting terminal for electrical conductors according to the preamble of claim 1.

Derartige Verbindungsklemmen mit zentrierendem Klemmanschluß, beispielsweise auch in Form von Reihenklemmen, sind in verschiedenen Ausführungsformen bekannt. Zu verweisen ist z. B. auf die DE-PS 923 562. Mit der dort gezeigten Anordnung können zwar unter entsprechender Zentrierung einwandfrei Einzeldrahtleiter unterschiedlichen Querschnitts festgelegt werden, doch ist diese Anordnung zur Klemmung mehrdrähtiger oder feindrähtiger Leiter, womöglich sogar auch noch verschiedener Leiter unterschiedlichen Querschnitts, ungeeignet, weil es hier zu einer undefinierten und unkontrollierten Zerteilung der Leiterdrähte an den Schrägflächen käme, mit dem Ergebnis, daß ein Teil der Drähte dann nur unzureichend geklemmt wird. Vergleichbar liegend die Verhältnisse auch bei dem DE-GM 16 01 608, bei dem darüber hinaus besonders kleine Einzeldrähte nicht mehr zuverlässig geklemmt werden können, weil vor deren Festklemmung das Druckstück auf die Klemmkörperwandung aufsetzen würde.Such connecting terminals with a centering terminal connection, for example also in the form of terminal blocks, are known in various embodiments. To be referred z. B. to DE-PS 923 562. Although the arrangement shown there can be properly set with appropriate centering, single-wire conductors of different cross-sections, but this arrangement is suitable for clamping stranded or fine-stranded conductors, possibly even different conductors of different cross-sections, because there would be an undefined and uncontrolled cutting of the conductor wires on the inclined surfaces, with the result that that part of the wires is then insufficiently clamped. Comparable, the situation is also in DE-GM 16 01 608, in which, in addition, particularly small individual wires can no longer be reliably clamped because the pressure piece would touch the clamping body wall before they were clamped.

Die DE-PS 11 16 294 zeigt eine Verbindungsklemme, mit der sowohl eindrähtige wie mehrdrähtige Leiter geklemmt werden können. Als Zentrierung sind hierbei im mittleren Bereich des Klemmkörpers nach innen vorstehende schräge Sicken eingeformt, für die entsprechende, sie vollständig aufnehmende Einprägungen am Druckstück vorgesehen sind. Eine einwandfreie Klemmung ist hier jedoch nur in einem relativ geringen Nennquerschnittsbereich der Leiter möglich. Bei größeren Einzeldrahtdurchmessern erfolgt nämlich alsbald die Klemmung nur noch auf den oberen Schrägkanten der Sicken, so daß die Klemmfläche gering ist und darüber hinaus der Draht einer erheblichen Knickkraft unterzogen wird. Um dies wenigstens für die Leiter passenden Nennquerschnitts zu vermeiden, müssen die Sicken so angeordnet sein, daß zwischen ihnen ein ebener Bodenabschnittsbereich verbleibt. Werden nun aber kleine Einzeldrähte von dem Druckstück auf diesem ebenen Bodenabschnitt geklemmt, unterliegen sie genau der gleichen Problematik, wie sie bei Anschlußklemmen ohne jedwede Leiterzentrierung auftritt, bei denen ein ebenflächiger Klemmkörperboden mit einem unterseitig ebenflächigen Druckstück zusammenwirkt. Liegt nämlich keine zentrierte Vorzugslage mehr vor und wird, wie häufig üblich, bei Verlegungsarbeiten u.dgl. am angeschlossenen Leiter gezogen und gezerrt, wandert das festgeklemmte Leiterende unter Kupferabrieb in der Klemmzone hin und her und es kommt sehr schnell zu einer Lockerung.DE-PS 11 16 294 shows a connecting terminal with which both solid and stranded conductors can be clamped. In this case, inclined beads protruding inward are formed as a centering in the central region of the clamping body, for which corresponding impressions which completely accommodate them are provided on the pressure piece. Correct clamping is only possible here in a relatively small nominal cross-sectional area of the conductors. In the case of larger individual wire diameters, the clamping is now only carried out on the upper oblique edges of the beads, so that the clamping area is small and the wire is also subjected to a considerable bending force. In order to avoid this, at least for the conductor having a suitable nominal cross section, the beads must be arranged in such a way that a flat area of the bottom section remains between them. However, if small individual wires are clamped by the pressure piece on this flat bottom section, they are subject to exactly the same problem as occurs with connection terminals without any conductor centering, in which a flat clamping body base interacts with a pressure piece that is flat on the underside. Because there is no central preferred location more before and, as is often the case, during laying work and the like. pulled and pulled on the connected conductor, the clamped conductor end moves back and forth under copper abrasion in the clamping zone and loosening occurs very quickly.

Bei der Ausgestaltung nach der DE-PS 11 16 294 ist auch eine Klemmung mehrerer Leiter unterschiedlichen Durchmessers unsicher.In the embodiment according to DE-PS 11 16 294, a clamping of several conductors of different diameters is also unsafe.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Verbindungsklemme der gattungsgemäßen Art zu schaffen, mit der in einem großen Querschnittsbereich eindrähtige, mehrdrähtige und feindrähtige Leiter einwandfrei geklemmt werden können.The present invention is therefore based on the object of providing a connecting clamp of the generic type with which solid, multi-wire and fine-stranded conductors can be clamped properly in a large cross-sectional area.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Anspruches 1.The solution according to the invention results from the characterizing part of claim 1.

Die konkave Verjüngung des Klemmkörperbodens gibt die gewünschte Zentrierungsmöglichkeit vor. Die in der Klemmzone an dem Druckstück vorgesehenen, über dessen Verjüngung vorstehenden Ansätze bewirken nun darüber hinaus mit ihren bodenseitigen Flächen, in Verbindung mit ihrer vollständigen Aufnahme in den Ausnehmungen der Wände des Klemmkörperbodens, daß es auch bei mehr- und feindrähtigen Leitern nicht vorkommen kann, daß diese in undefinierter Zerteilung in weiten Bereichen der schrägen Verjüngungsflächen geklemmt werden. Bewegt sich nämlich das Druckstück zur Klemmung auf den Bodenbereich des Klemmkörpers zu, schieben die bodenseitigen Flächen der seitlichen Ansätze im Rahmen des Möglichen die Leiterdrähte von den schrägen Verjüngungsflächen auf die Mittellängsachse, d.h. die am tiefsten liegende Zone der Zentrierung zu. Dies hat auch zur Folge, daß sogar mehrere Einzeldrahtleiter mit Einzeldrähten unterschiedlichen Querschnitts einwandfrei festgeklemmt werden können, weil es durch diese sammelnde Zuführung der Drähte zum mittleren tiefstliegenden Zentralbereich der Zentrierung hin hier zu einer optimierenden Leiterdrahtsammlung kommt, die eine einwandfreie Festklemmung auch von Drähten unterschiedlicher Durchmesser gewährleistet.The concave taper of the bottom of the sprag provides the desired centering option. The projections provided on the pressure piece in the clamping zone and projecting beyond its tapering now also cause, with their bottom surfaces, in conjunction with their complete reception in the recesses in the walls of the clamping body base, that it cannot occur even with multi-stranded and fine-stranded conductors, that these are clamped in an undefined division in large areas of the oblique tapered surfaces. If the pressure piece for clamping moves towards the bottom area of the clamping body, push the bottom surfaces of the lateral side As far as possible, add the conductor wires from the oblique tapered surfaces to the central longitudinal axis, ie the lowest lying zone of the centering. This also has the consequence that even several individual wire conductors with individual wires of different cross-sections can be clamped properly, because this collecting supply of the wires to the central, deepest central area of the centering leads to an optimizing conductor wire collection, which also ensures perfect clamping of wires of different diameters guaranteed.

Andererseits liegt es auf der Hand, daß Einzeldrähte in einem sehr weiten Nennquerschnittsbereich völlig einwandfrei großflächig und ohne Belastung mit einer Knickkraft geklemmt werden können. Dadurch, daß durch die vollständige Aufnahme der Ansätze am Druckstück in den Ausnehmungen des Klemmkörperbodens das Druckstück bis praktisch vollständig an den Boden heranbewegt werden kann, werden auch sehr kleine Einzeldrähte noch einwandfrei geklemmt, und dies auch in einer bevorzugten Zentrierungslage in der'verjüngungsspitze des Klemmkörperbodens.On the other hand, it is obvious that individual wires in a very wide nominal cross-sectional area can be clamped perfectly and without stress with a kinking force. Due to the fact that through the complete inclusion of the lugs on the pressure piece in the recesses of the clamp body bottom, the pressure piece can be moved almost completely to the bottom, even very small individual wires are still clamped perfectly, and this also in a preferred centering position in the 'tapering tip of the clamp body bottom .

Weitere Ausgestaltungen derartiger Verbindungsklemmen sind in den Unteransprüchen gekennzeichnet.Further configurations of such connecting terminals are characterized in the subclaims.

Speziell für mehr- und feindrähtige Leiter großen Nennquerschnitts ist eine besondere Ausführungsform dergestelt vorgesehen, daß in die mittlere Abflachung der Verjüngungsspitze des Druckstückes eine sich über die ganze Klemmzone erstreckende Hohlkehle eingearbeitet ist. Zusammen mit der entgegengesetzt gekrümmten Verjüngungsspitze des Klemmkörpers bildet diese Hohlkehle einen sammelnden und zentrierenden Aufnahmeraum für die Einzeldrähte, die hier in besonders zuverlässiger Zusammenballung besonders zuverlässig geklemmt werden.Especially for multi-strand and fine-stranded conductors of large nominal cross-section, a special embodiment is provided in such a way that an overlap in the central flattening of the tapering tip of the pressure piece the fillet extending into the entire clamping zone is incorporated. Together with the oppositely curved tapering tip of the clamping body, this fillet forms a collecting and centering receiving space for the individual wires, which are clamped here particularly reliably in a particularly reliable agglomeration.

Ausführungsbeispiele derartiger Verbindungsklemmen werden nachstehend unter Bezugnahme auf die Zeichnung näher beschrieben.Embodiments of such connecting terminals are described below with reference to the drawing.

Die in den Figuren dargestellten Stromschienen und Zugbügel gehören zu einem Verbindungsklemmentyp, bei dem in einem Isolierstoffgehäuse zwei Klemmanschlüsse vorgesehen sind, die jeweils einen hohlen Klemmkörper in Form eines Zugbügels 1 haben, durch den oberseitig eine Klemmschraube 2 geschraubt ist. Die leitende Verbindung zwischen den beiden Zugbügeln 1 der beiden Klemmanschlüsse geschieht durch eine Stromschiene 3, deren beide Enden jeweils in einem der Zugbügel 1 liegen und deren Enden somit die Druckstücke bilden, die mittels der oberseitig auf sie aufsetzenden Klemmschrauben 2 einen eingelegten ein- oder mehrdrähtigen Leiter oder mehrere eingelegte Leiter mit ihren Unterseiten gegen den Bodenbereich des jeweiligen Zugbügels 1 klemmend festlegen.The busbars and drawbars shown in the figures belong to a type of connection clamp in which two clamp connections are provided in an insulating housing, each of which has a hollow clamp body in the form of a drawbar 1, through which a clamping screw 2 is screwed on the upper side. The conductive connection between the two tension clamps 1 of the two clamp connections takes place by means of a busbar 3, the two ends of which each lie in one of the tension clamps 1 and the ends of which thus form the pressure pieces which, by means of the clamping screws 2 placed on top of them, insert an inserted or stranded wire Fix the conductors or several inserted conductors with their undersides by clamping against the bottom area of the respective pull bracket 1.

Der Bodenbereich des Zugbügels 1 weist eine konkave, zur Mittelachse hin konvergierende Verjüngung auf, so daß sich zwei schräg nach unten zur Zugbügelmittellängsachse hin verlaufende Bodenwände 4 ergeben, deren Schnittpunkt die Verjüngungsspitze 5 bildet, die abgerundet ausgebildet ist. Die Bodenwände 4 bilden für die festzuklemmenden Leiter eine Zentrierung.The bottom region of the tension bow 1 has a concave taper converging towards the central axis, so that there are two bottom walls 4 which run obliquely downward towards the tension bow central longitudinal axis, the intersection of which forms the tapering tip 5, which is rounded. The bottom walls 4 form a centering for the conductor to be clamped.

Das zugehörige, im dargestellten Ausführungsbeispiel durch die Stromschiene 3 gebildete Druckstück ist unterseitig beidseitig mit entsprechenden Verjüngungen in Form von eingearbeiteten Schrägflächen 6 versehen, die zur Bodenseite der Stromschiene hin konvergieren, wobei auch hier die Verjüngungsspitze eine Abflachung 7 hat. Die Dimensionierung ist so gewählt, daß von den Verjüngungen und Schrägungen her das entsprechende Stromschienenende vollständig an den zentrierenden Boden des Zugbügels 1 herangedrückt werden kann. Es versteht sich, daß sich die Schrägflächen 6 auf der Unterseite der Stromschiene nur in deren Klemmzone, also dem mit dem Zugbügel 1 zusammenwirkenden Bereich, befinden.The associated pressure piece, formed by the busbar 3 in the exemplary embodiment shown, is provided on the underside on both sides with corresponding tapers in the form of incorporated inclined surfaces 6, which converge towards the bottom side of the busbar, the tapering tip also here Flattening 7 has. The dimensioning is chosen so that the corresponding busbar end can be pressed completely against the centering bottom of the tension bracket 1 from the tapering and sloping. It goes without saying that the inclined surfaces 6 are located on the underside of the busbar only in the clamping zone thereof, that is to say in the region which interacts with the tension bracket 1.

In dieser Klemmzone an den jeweiligen Enden der Stromschiene 3 sind nun, gesehen über die Klemmzonenlänge, jeweils an mindestens einer Stelle, im dargestellten Ausführungsbeispiel in der Mitte der Klemmzone, seitlich über die Schrägflächen 6 vorstehende Ansätze 8 vorgesehen, deren bodenseitige Flächen 9 zumindest annähernd in einer Ebene mit der mittigen Abflachung 7 liegen. Im dargestellten Ausführungsbeispiel sind diese Ansätze 8 in einfacher Weise dadurch gebildet, daß in diesem Bereich der volle Stromschienenquerschnitt stehengeblieben ist und auf beiden Seiten des Ansatzes 8 jeweils die Schrägflächen 6 eingearbeitet sind.In this clamping zone at the respective ends of the busbar 3, as seen over the clamping zone length, in each case at least at one point, in the exemplary embodiment shown in the middle of the clamping zone, projections 8 are provided laterally over the inclined surfaces 6, the bottom surfaces 9 of which at least approximately in lie in a plane with the central flattening 7. In the illustrated embodiment, these approaches 8 are formed in a simple manner in that the full conductor rail cross section has remained in this area and the inclined surfaces 6 are incorporated on both sides of the approach 8.

In dem Zugbügel 1 sind ferner in seinen schrägen Bodenwänden 4 Ausnehmungen 11 vorgesehen, die so groß bemessen sind, daß sie die Ansätze 8 vollständig aufnehmen können, also die Stromschiene trotz der Ansätze 8 weiterhin vollständig gegen den Boden des Zugbügels 1 angedrückt werden kann.In the drawbar 1 4 recesses 11 are also provided in its sloping bottom walls, which are dimensioned so large that they can completely accommodate the lugs 8, that is, the busbar despite the lugs 8 can still be completely pressed against the bottom of the drawbar 1.

Im dargestellten Ausführungsbeispiel sind diese Ausnehmungen durch entsprechende Ausprägesicken 12 gebildet. In Abwandlung hierzu ist es auch möglich, in diesem Bereich die Bodenwände lochförmig auszustanzen.In the exemplary embodiment shown, these recesses are formed by corresponding embossed beads 12. As a variation of this, it is also possible to move into the punch out the bottom walls in this area.

Durch die schrägen Bodenwände 4 des Zugbügels 1 in ihrer Funktion als Zentrierung können im Zusammenwirken mit dem entsprechend abgeschrägten als Druckstück wirkenden Ende der Stromschiene 3 Einzeldrahtleiter in einem außerordentlich großen Nennquerschnittsbereich zuverlässig in einer eindeutig definierten Vorzugslage festgelegt werden, ohne daß die Gefahr besteht, daß ein solcher festgelegter Leiter bei Handhabungen daran unkontrolliert in der Klemmzone hin- und herschwenkt und sich durch Kupferabrieb lockert. Dadurch, daß das Stromschienenende praktisch vollständig an den Boden des Zugbügels herangedrückt werden kann, können auch sehr kleine Einzeldrähte noch zuverlässig geklemmt werden. Die Klemmung ist im Bodenbereich des Zugbügels 1 jeweils großflächig.Due to the sloping bottom walls 4 of the tension bracket 1 in their function as centering, in cooperation with the correspondingly bevelled end of the busbar acting as a pressure piece, 3 single-wire conductors can be reliably fixed in a clearly defined preferred position in an extraordinarily large nominal cross-sectional area, without the risk that a such fixed conductor swings back and forth in the clamping zone in an uncontrolled manner and loosens due to copper abrasion. Due to the fact that the conductor rail end can be pressed almost completely against the bottom of the pull bracket, even very small individual wires can still be reliably clamped. The clamping is large in the bottom area of the tension bracket 1.

Es können aber auch mehrdrähtige und feindrähtige Leiter sowie auch mehrere Leiter mit Einzeldrähten jeweils unterschiedlichen Querschnitts völlig einwandfrei zentriert festgelegt werden. Die Ansätze 8 in den Klemmzonenbereichen der Stromschiene 3 nämlich, die ja in der Klemmphase seitlich auch noch nach außen über die schrägen Bodenwände 4 des Zugbügels 1 hervorstehen, bewirken, daß es bei mehr- und feindrähtigen Leitern nicht etwa zu einer undefinierten Zerteilung der einzelnen Drähte und deren mehr oder weniger zufälliger Festklemmung irgendwo auf den schrägen Bodenwänden 4 kommt, sondern daß diese Drähte praktisch in einer Art Sammelbewegung von den Ansätzen immer bestmöglich in den hohlkehlenförmigen Bodenbereich in der Mittellängsachse zusammengeführt und zusammengedrückt werden und hier in optimaler Form in dieser mittelachsigen Hohlung auch in enger gegenseitiger Anlage aneinander festgelegt werden. Insbesondere können so auch zuverlässig mehrere Leiter mit Einzeldrähten unterschiedlichen Querschnitts einwandfrei festgelegt werden.However, multi-stranded and fine-stranded conductors as well as several conductors with individual wires, each with a different cross-section, can be fixed perfectly centered. The lugs 8 in the clamping zone areas of the busbar 3 namely, which in the clamping phase also protrude laterally outwards beyond the sloping bottom walls 4 of the tension bracket 1, have the effect that there is no undefined division of the individual wires in the case of multi-stranded and fine-stranded conductors and their more or less accidental clamping somewhere on the sloping floor walls 4, but that these wires practically in a kind of collecting movement from the approaches always in the best possible way into the hollow-shaped floor area in the The central longitudinal axis are brought together and pressed together and are optimally fixed in this central-axis cavity, even in close mutual contact. In particular, several conductors with individual wires of different cross sections can also be reliably fixed in this way.

Die Stromschiene 3 weist angrenzend an die Klemmzonen an ihren Enden noch einen Abschnitt 13 auf, der den vollen Stromschienenquerschnitt hat. Die Abschnitte 13 liegen auf der Leitereinsteckseite und können mit ihren Unterseiten die Sammlungs- und Zusammenführungswirkung der Ansätze 8 im mittleren Bereich der Klemmzone unterstützen. Dies gilt auch für die innen an die Klemmzonen angrenzenden Abschnitte 13a.The busbar 3, adjacent to the clamping zones, also has a section 13 at its ends, which has the full busbar cross section. The sections 13 are on the conductor insertion side and can support the collection and merging effect of the lugs 8 in the central region of the clamping zone with their undersides. This also applies to the sections 13a adjacent to the inside of the clamping zones.

Zweckmäßig sind die Zugbügel 1 und die Stromschienen 3 in ihren miteinander zusammenwirkenden, die Leiter beaufschlagenden Flächenzqnen geriffelt ausgebildet. Bei den Zugbügeln 1 erstreckt sich die Riffelung zweckmäßig über die schrägen Bodenwände 4 und die abgerundete Verjüngungsspitze 5. Bei der Stromschiene 3 erstreckt sich die Riffelung über die mittelachsige Abflachung 7, die bodenseitigen Flächen 9 der Ansätze 8 und die Bodenfläche der Abschnitte 13.Appropriately, the tension bracket 1 and the busbars 3 are formed in their interacting surfaces acting on the conductors q nen corrugated. In the case of the tension clamps 1, the corrugation expediently extends over the inclined bottom walls 4 and the rounded taper tip 5. With the busbar 3, the corrugation extends over the central-axis flattening 7, the bottom surfaces 9 of the lugs 8 and the bottom surface of the sections 13.

Bei dem in Fig. 6 dargestellten Ausführungsbeispiel eines Druckstückes in Form einer Stromschiene 3' ist bei im übrigen gleichem Aufbau in der Klemmzone der Bereich der Abflachung an der Verjüngungsspitze am Ende der Schrägflächen 6 als nach innen oben weisende Hohlkehle 7' ausgebildet. Zusammen mit der mittelachsigen Abrundung der Verjüngungsspitze 5 des zugehörigen Zugbügels 1 bildet diese Hohlkehle 7' einen Sammel- und Aufnahmeraum, der in besonderem Maße dazu geeignet ist, bei mehr- und feindrähtigen Leitern großen Nennquerschnitts die Vielzahl der einzelnen Drähte besonders sicher sammelnd und kompaktierend in zentrierter, klar definierter Lage festzuklemmen.In the embodiment of a pressure piece in the form of a busbar 3 'shown in FIG. 6 with otherwise the same structure in the clamping zone, the area of the flattening at the tapering tip at the end of the inclined surfaces 6 is formed as a groove 7 'pointing upwards. Together with the central-axis rounding of the tapering tip 5 of the associated tension bow 1, this fillet 7 'forms a collecting and receiving space which is particularly suitable for collecting the multiplicity of individual wires in a particularly secure manner in the case of multi-stranded and fine-stranded conductors of large nominal cross section centered, clearly defined position.

Abweichend vom dargestellten Ausführungsbeispiel gibt es Verbindungsklemmentypen, bei denen die leitende Verbindung von Klemmanschluß zu Klemmanschluß über die Klemmkörper selbst, die leitend untereinander verbunden sind, geschieht, während unterseitig an den Klemmschrauben gesonderte Formteile als Druckstücke vorgesehen sind. Auch bei diesem Verbindungsklemmentyp läßt sich das vorstehend geschilderte Konstruktionsprinzip verwirklichen.In a departure from the exemplary embodiment shown, there are connection terminal types in which the conductive connection from terminal connection to terminal connection takes place via the clamping bodies themselves, which are conductively connected to one another, while on the underside, separate molded parts are provided as pressure pieces on the clamping screws. The construction principle described above can also be realized with this type of connection terminal.
