Definitions

  • the invention relates to a connecting terminal as defined in claim 1.
  • connection terminals with conductor insertion openings arranged on opposite housing sides which are also referred to as double terminals or double-sided connection terminals, are known, for example, from US Pat DE 10 2013 101 830 A1 known.
  • Another terminal is from the EP 2 605 335 A2 known.
  • the invention has for its object to provide a smaller connecting clamp.
  • connection clamp mentioned at the outset in that an extended end section of the contact leg of the first and the second clamping spring is suspended in one through opening of the busbar.
  • a particularly compact busbar can be used to fasten the first and second clamping springs.
  • forces acting on the insulating housing of the first and second clamping springs can be reduced to an acceptable order of magnitude.
  • first and second clamping springs can be arranged closer to one another and can also touch, which opens up the possibility of making the busbar shorter than known connecting terminals. This can save material on the busbar.
  • the connecting clamp can be made shorter in the longitudinal direction of the conductor rail.
  • connection terminal can be realized in a particularly flat construction in this way.
  • busbar can be implemented as a flat component, which minimizes the material and manufacturing costs of the busbar and also has a favorable effect on an overall flat design of the connecting terminal.
  • the through opening of the busbar can in particular have a non-circular shape in plan view of the busbar, for example rectangular, possibly with rounded corner areas. This improves the attachment of the first and second clamping springs to the busbar.
  • the respective elongated end sections of the contact legs of the first and second clamping springs can thus be suspended in one and the same through opening of the busbar.
  • the busbar does not have to have a multiplicity of openings, so that a mechanical weakening of the busbar and a deterioration in the electrical conductivity can be minimized.
  • connection terminal can be implemented as a single-pole connection terminal, i.e. with only one busbar, or as a multi-pole connection terminal, e.g. in such a way that several individual connection terminals are lined up next to one another, so that their busbars are arranged essentially parallel to one another.
  • the multi-pole connecting terminal can in particular be designed as a separable connecting terminal that can be assembled by the user to the desired number of poles.
  • the connecting clamp has a first actuating lever for opening and closing the first spring-loaded terminal connection by acting on the clamping arm of the first clamping spring when the first actuating lever is actuated and / or a second actuating lever for opening and closing the second spring-loaded terminal connection by acting on the Has clamping leg of the second clamping spring when actuating the second actuating lever.
  • the first and / or the second clamping spring is loop-shaped, the respective contact leg being bent in an extended end section of the respective clamping spring in the direction of the busbar.
  • the first clamping spring touches the second clamping spring in the region of its respective contact leg.
  • the contact leg of the first clamping spring forms a conductor stop when the first conductor is inserted into the insulating material housing and / or the contact leg of the second clamping spring forms a conductor stop of the second conductor when it is inserted into the insulating material housing.
  • This has the advantage that no additional measures are required to implement a conductor stop in the respective conductor insertion area of the connection terminal, such as an insulating wall.
  • This also allows the insulating material housing to be optimized with regard to the necessary material and construction.
  • the conductor stop in particular prevents the conductor from being inserted too far into the connecting terminal. The user can easily detect haptically when a conductor is inserted sufficiently deep into the connecting terminal.
  • a ladder stop e.g. the area of the respective clamping spring which is bent in the direction of the busbar is used.
  • the Through opening in the busbar is designed as a nozzle (material passage).
  • the nozzle can have, for example, a wall made of the material of the busbar, which wall projects from the surface of the busbar surrounding the busbar opening and surrounds the busbar opening.
  • the area of the contact leg of the first clamping spring which is suspended in the through hole engages behind the passage opening of the busbar on the side of the busbar remote from the first clamping point and / or the area of the contact leg of the second clamping spring which is hooked into the through opening engages behind the through opening of the busbar on the side of the busbar facing away from the second clamping point.
  • the first clamp spring and / or the second clamp spring can be located below the busbar, i.e. on the side facing away from the respective clamping point, are hung in and is held securely on the conductor rail without additional mechanical fixing means.
  • the area of the contact leg of the respective clamping spring suspended in the through-opening can e.g. reach behind the aforementioned wall of the nozzle.
  • the contact leg of the first clamping spring is supported on the busbar on its side facing the first clamping point and / or the contact leg of the second clamping spring is supported on the busbar on its side facing the second clamping point.
  • the clamping spring on the other side of the busbar, on which it does not reach behind the through opening can be fixed to the busbar and securely supported there.
  • the contact leg of the respective clamping spring has a greater width in the region in which the support is provided on the busbar than the through opening.
  • the first and / or the second clamping spring can e.g. have a spring arch, via which the contact leg is connected to the clamping leg.
  • the clamping spring can e.g. overall be V-shaped, e.g. in a kind of loop shape.
  • the first clamping spring and / or the second clamping spring is supported on the insulating material housing.
  • the clamping spring can also be fixed in the insulating housing, e.g. in the contact leg region which adjoins a spring arch of the clamping spring, via which the contact leg is connected to the clamping leg.
  • the connecting terminal on a respective housing side of the insulating material housing has a plurality of conductor insertion openings arranged next to one another, each of which has spring-loaded terminal connections, each with a clamping spring assigned to a conductor insertion opening, with extended end sections of clamping springs arranged next to one another being suspended in the same through opening of the busbar.
  • a connection terminal with a plurality of conductor entry openings arranged side by side on a housing side of the insulating material housing is also referred to as a double connection terminal (with two conductor entry openings arranged side by side) or multiple connection terminal (with more than side-by-side conductor entry openings).
  • Connection terminal 9 shown is constructed essentially symmetrically with respect to a vertical axis of symmetry. It has a first spring clamp connection 1 and a second spring clamp connection 2 on the left and right of the vertical axis of symmetry.
  • the first and the second spring terminal connection 1, 2 are arranged in an insulating material housing 4, 5 of the connecting terminal 9.
  • the insulating material housing 4, 5 can be formed, for example, at least in two parts, for example from an upper housing part 4 and one bottom part 5 which can be connected to the upper housing part 4 by latching elements 50.
  • the first spring-loaded terminal connection 1 has a first clamping spring 11, which is angled in multiple loops.
  • the first clamping spring 11 has at one end a clamping leg 12 which is used to clamp an electrical conductor inserted through a first conductor insertion opening 10 against a first clamping point 31 of a busbar 3.
  • a spring arch 14 adjoins the clamping leg 12 of the first clamping spring 11, to which a contact leg 15 of the first clamping spring 11 then connects.
  • the contact leg 15 lies against an inner wall region 41 of the insulating material housing 4, 5 and is supported on it at least in part with respect to the forces absorbed by the clamping leg 12.
  • the first clamping spring 11 extends further in the region of the contact leg 15 into an extended end section 16, in which the material of the first clamping spring 11 is finally bent in a vertical region 17 in the direction of the busbar 3.
  • the end section 16 of the contact leg 15 extends beyond the vertical region 17 further downward through a through opening 30 of the busbar 3 and is finally suspended in the through opening 30 of the busbar 3, e.g. in that an end piece 18 of the end section 16 is further angled and thus engages behind the busbar 3, in particular in a region of the busbar 3 designed as a nozzle 33, which surrounds the through opening 30 in a base shape.
  • the second clamping spring 21 can, for example, be shaped in the same way as the first clamping spring 11.
  • the second spring-force clamping connection 2 has a second clamping spring 21 that is bent several times in a loop.
  • the second clamping spring 21 has a clamping leg 22 at one end, which serves to clamp an electrical conductor inserted through a second conductor insertion opening 20 against a second clamping point 32 of the busbar 3.
  • second clamping spring 21 is present, on which the clamping leg 22 can be actuated via an actuating lever 29 for opening and closing the second spring-loaded clamping connection 2.
  • a spring arch 24 adjoins the clamping leg 22 of the second clamping spring 21, to which a contact leg 25 of the second clamping spring 21 then connects.
  • the contact leg 25 bears against an inner wall area 42 of the insulating material housing 4, 5 and is supported on it at least in part against the forces absorbed by the clamping leg 22.
  • the second clamping spring 21 extends in the region of the contact leg 25 further into an extended end section 26, in which the material of the second clamping spring 21 is finally bent in a vertical region 27 in the direction of the busbar 3.
  • the end section 26 of the contact leg 25 extends beyond the vertical region 27 further down through the through opening 30 of the busbar 3 and is finally suspended in the through opening 30 of the busbar 3, e.g. in that an end piece 28 of the end section 26 is further angled and thus engages behind the busbar 3, in particular in the region of the busbar 3 designed as a nozzle 33.
  • the Figure 1 shows the first spring-loaded terminal connection 1 with the first actuating lever 19 open, such that the first clamping point 31 is not touched by the clamping leg 12 and an electrical conductor which may have been previously clamped there can be removed. It can be seen that the clamping leg 12 of the first clamping spring 11 is then removed from the first clamping point 31.
  • the second spring-loaded terminal connection 2 is shown in the closed state, ie the second actuating lever 29 is in the closed position. In this state, the clamping leg 22 of the second clamping spring 21 touches the end of the second clamping point 32 of the busbar 3.
  • busbar 3 has embossments in the region of its first and second clamping points 31, 32, by means of which the material of the busbar 3 is exposed somewhat upwards, ie in the direction of the respective clamping leg 12, 22. This improves the clamping of a connected electrical conductor.
  • the busbar 3 is formed in one piece as a flat, short busbar piece. By designing the through opening 30 with the nozzle 33, the busbar 3 is mechanically stabilized in this area and also optimized with regard to the electrical line.
  • the clamping springs 11, 21 cannot initially be bent outward in their respective end pieces 18, 28, ie before they are fastened to the busbar 3, as in FIG Figure 1 is recognizable. They can initially run essentially in a straight line. After the clamping springs 11, 21 have been installed in the through opening 30 of the busbar 3, a further production step takes place in that the end pieces 18, 28 are bent outwards, ie in the direction of the respective conductor insertion opening 10, 20, and then engage behind the nozzle 33.
  • the first clamping spring 11 is supported in the vertical region 17 on the vertical region 27 of the second clamping spring 21, ie the clamping springs 11, 21 are mutually supported in the region of their vertical sections 17, 27.
  • the vertical region 17 also forms a conductor stop when the first conductor is inserted into the insulating housing.
  • the vertical region 27 also forms a conductor stop when the second conductor is inserted into the insulating material housing.
  • the connecting clamp 9 can be designed as a simple connecting clamp, in which there is a conductor insertion opening 10, 20 on each side. It can also be designed as a double or multiple terminal. In this case, two or more first conductor insertion openings 10 and two or more second conductor insertion openings 20 are arranged side by side on each side. A different configuration of the respective actuating lever 19, 29 can be advantageous for such embodiments.
  • the Figure 2 shows in the lower area an advantageous embodiment of an actuating lever 6, which can be used as the first or second actuating lever 19, 29, in the event that the connecting terminal has only one conductor insertion opening 10, 20 on each side.
  • the operating lever 6 has a manual operating area 60 (handle area), on which the operating lever 6 can be operated by a user.
  • the actuating lever 6 also has a bearing axis 61, by means of which it can be used to mount insulating material housings 4, 5.
  • the actuating lever 6 is fork-shaped in the region of the bearing axis 61, with a region 65 which is recessed in the middle and by means of which the actuating lever 6 can be placed over the clamping spring lying in between.
  • the clamping spring then has laterally projecting areas 13 and 23, on which the clamping spring can be acted upon by actuating areas 62 of the actuating lever 6.
  • a rear contour of the actuating lever 6 has two bearing regions 63, 64 arranged at an angle to one another, via which the actuating lever is supported in the insulating material housing and / or on the busbar 3. In the closed actuation position, the actuation lever 6 rests with the bearing area 63, in the open position with the bearing area 64.
  • the bearing axis 61 is received in a groove (not shown) arranged in the housing upper part 4 and oriented essentially perpendicular to the busbar 3 through the bearing areas 63, 64 which are on the busbar 3 during the pivoting movement of the actuating lever 19, 29 to be able to accommodate conditional deflection occurring during the pivoting movement of the actuating lever 19, 29.
  • the Figure 2 shows in the upper area an embodiment of an actuating lever 6, which is designed for a connecting terminal, in which there are two spring-loaded terminal connections arranged side by side on each housing side. Accordingly, the entire actuating lever 6 is made wider and has two recessed areas 65 lying next to one another, in which respective clamping springs can be passed. Correspondingly, three areas of application 62 are provided. Here, the middle loading area 62 acts simultaneously on the two adjacent clamping springs on one side of the connecting terminal 9.
  • the Figure 3 shows in an enlarged detail the attachment of the clamping springs on the busbar 3.
  • a double clamping spring which has two juxtaposed contact legs and clamping legs and is thus designed for a connecting clamp, in which there are two spring-cage clamp connections arranged next to each other on the housing side.
  • a partial section of the respective vertical regions 27 of the clamping springs is shown here. These then unite to form a common fastening section 271, which is finally fastened to the nozzle 33 of the busbar 3 via the end pieces 28 which are guided through the through opening 30.
  • the left end piece 28 has already been bent over, as in FIG Figure 1 shown, and the right end piece 28 is not yet bent.
  • the clamping spring rests on the busbar 3 with contact surfaces 270.
  • the Figure 4 shows an enlarged detail view of a possible shape of the busbar 3 in the area of the passage opening 30.
  • the passage opening 30 does not have to be circular, for example, but can, as shown, essentially be rectangular with rounded corners. Accordingly, the wall area of the nozzle 33 surrounds this through opening 30.
  • connection terminal 9 corresponds in its essential structure to that previously based on the Figures 1 to 4 explained connection terminal 9. Therefore, the differences are essentially discussed below.
  • FIG. 5 shows, there are two adjacent conductor insertion openings 10, 20 in each case at the double connection terminal 9 on each conductor insertion side. In the closed position, for example, the clamping legs 22 are visible when looking into the conductor insertion openings 20.
  • the Figure 6 shows a comparable operating lever 6, as in Figure 2 shown in the figure above.
  • the operating lever according to Figure 6 can be used as an operating lever 19 and 29, as in the Figure 7 can be seen.
  • the busbar 3 also has a through opening 30 which, however, is formed here without the nozzle 33.
  • the vertical regions 17, 27 of the end sections 16, 26 of the clamping springs 11, 21 also protrude through the through opening 30 in this embodiment.
  • the vertical regions 17, 27 do not end in further angled end pieces 18, 28 as in the embodiment explained first. Instead, they run in straight end pieces 71, 72 further in the vertical direction.
  • respective material areas 73, 74 which are exposed in the sense of a latch or barb, are provided on the end pieces 71, 72.
  • the material areas 73, 74 can be deflected resiliently, so that the clamping springs 11, 21 in the illustrated back-to-back configuration with the end pieces 71, 72 can be inserted through the openings 30 of the busbar 3.
  • the material areas 73, 74 initially deflect. If this plug-in process is carried out, the material areas 73, 74 spring out again and engage behind the busbar 3 and thus fix the clamping springs 11, 21 on the busbar 3.
  • each clamping spring 11 it is possible for each clamping spring 11 to have its own end piece 71, 72 with an exposed material area 73, 74. This is also necessary for a single connection terminal. With the double connection clamp 9 described here, this can also be implemented in such a way that the clamping springs are formed independently of one another by their own end pieces 71, 72 with projecting material areas 73, 74 arranged thereon.
  • adjacent clamping springs lying next to one another can also be formed via a common end piece 71 or 72, each with a protruding material region 73 or 74.

Description

Die Erfindung betrifft eine Verbindungsklemme wie in Anspruch 1 definiert.The invention relates to a connecting terminal as defined in claim 1.

Solche Verbindungsklemmen mit auf gegenüberliegenden Gehäuseseiten angeordneten Leitereinführöffnungen, die auch als Doppelklemmen oder doppelseitige Anschlussklemmen bezeichnet werden, sind z.B. aus der DE 10 2013 101 830 A1 bekannt. Eine weitere Anschlussklemme ist aus der EP 2 605 335 A2 bekannt.Such connection terminals with conductor insertion openings arranged on opposite housing sides, which are also referred to as double terminals or double-sided connection terminals, are known, for example, from US Pat DE 10 2013 101 830 A1 known. Another terminal is from the EP 2 605 335 A2 known.

Der Erfindung liegt die Aufgabe zugrunde, eine kleinerbauende Verbindungsklemme anzugeben.The invention has for its object to provide a smaller connecting clamp.

Diese Aufgabe wird bei der eingangs genannten Verbindungsklemme dadurch gelöst, dass ein verlängerter Endabschnitt des Anlageschenkels der ersten und der zweiten Klemmfeder in der einen Durchgangsöffnung der Stromschiene eingehängt ist. Auf diese Weise kann eine besonders kompakte Stromschiene zum Befestigen der ersten und der zweiten Klemmfeder genutzt werden. Auf diese Weise können zugleich auf das Isolierstoffgehäuse einwirkende Kräfte der ersten und der zweiten Klemmfeder auf eine akzeptable Größenordnung verringert werden.This object is achieved in the connection clamp mentioned at the outset in that an extended end section of the contact leg of the first and the second clamping spring is suspended in one through opening of the busbar. In this way, a particularly compact busbar can be used to fasten the first and second clamping springs. In this way, forces acting on the insulating housing of the first and second clamping springs can be reduced to an acceptable order of magnitude.

Ein weiterer Vorteil der Erfindung besteht darin, dass die erste und die zweite Klemmfeder näher aneinander angeordnet werden können und sich auch berühren können, was die Möglichkeit eröffnet, die Stromschiene gegenüber bekannten Verbindungsklemmen kürzer zu gestalten. Hierdurch kann eine Materialeinsparung an der Stromschiene erzielt werden. Zudem kann die Verbindungsklemme in Längserstreckungsrichtung der Stromschiene kürzer bauend realisiert werden.Another advantage of the invention is that the first and second clamping springs can be arranged closer to one another and can also touch, which opens up the possibility of making the busbar shorter than known connecting terminals. This can save material on the busbar. In addition, the connecting clamp can be made shorter in the longitudinal direction of the conductor rail.

Insgesamt kann die Verbindungsklemme auf diese Weise besonders flachbauend realisiert werden.Overall, the connection terminal can be realized in a particularly flat construction in this way.

Ein weiterer Vorteil ist, dass die Stromschiene als flachbauendes Bauteil realisiert werden kann, was die Material- und Herstellungskosten der Stromschiene minimiert und sich zudem günstig auf ein insgesamt flachbauendes Design der Verbindungsklemme auswirkt. Die Durchgangsöffnung der Stromschiene kann in Draufsicht auf die Stromschiene insbesondere eine nicht-kreisrunde Form haben, z.B. rechteckig ggf. mit abgerundeten Eckbereichen. Hierdurch wird die Einhänge-Befestigung der ersten und der zweiten Klemmfeder an der Stromschiene verbessert.Another advantage is that the busbar can be implemented as a flat component, which minimizes the material and manufacturing costs of the busbar and also has a favorable effect on an overall flat design of the connecting terminal. The through opening of the busbar can in particular have a non-circular shape in plan view of the busbar, for example rectangular, possibly with rounded corner areas. This improves the attachment of the first and second clamping springs to the busbar.

Vorteilhafterweise können somit die jeweiligen, verlängerten Endabschnitte der Anlageschenkel der ersten und der zweiten Klemmfeder in ein und derselben Durchgangsöffnung der Stromschiene eingehängt sein. Auf diese Weise muss die Stromschiene nicht eine Vielzahl von Öffnungen aufweisen, so dass eine mechanische Schwächung der Stromschiene sowie eine Verschlechterung der elektrischen Leitfähigkeit minimiert werden kann.Advantageously, the respective elongated end sections of the contact legs of the first and second clamping springs can thus be suspended in one and the same through opening of the busbar. In this way, the busbar does not have to have a multiplicity of openings, so that a mechanical weakening of the busbar and a deterioration in the electrical conductivity can be minimized.

Die Verbindungsklemme kann als einpolige Verbindungsklemme realisiert werden, d.h. mit nur einer Stromschiene, oder als mehrpolige Verbindungsklemme, z.B. in der Art, dass mehrere einzelne Verbindungsklemmen nebeneinander gereiht sind, sodass deren Stromschienen im Wesentlichen parallel zueinander angeordnet sind. Die mehrpolige Verbindungsklemme kann insbesondere als teilbare Verbindungsklemme ausgebildet sein, die vom Anwender auf die gewünschte Polzahl konfektionierbar ist.The connection terminal can be implemented as a single-pole connection terminal, i.e. with only one busbar, or as a multi-pole connection terminal, e.g. in such a way that several individual connection terminals are lined up next to one another, so that their busbars are arranged essentially parallel to one another. The multi-pole connecting terminal can in particular be designed as a separable connecting terminal that can be assembled by the user to the desired number of poles.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Verbindungsklemme einen ersten Betätigungshebel zum Öffnen und Schließen des ersten Federkraftklemmanschlusses durch Beaufschlagung des Klemmschenkels der ersten Klemmfeder bei Betätigung des ersten Betätigungshebels und/oder einen zweiten Betätigungshebel zum Öffnen und Schließen des zweiten Federkraftklemmanschlusses durch Beaufschlagung des Klemmschenkels der zweiten Klemmfeder bei Betätigung des zweiten Betätigungshebels aufweist. Dies hat den Vorteil, dass der erste Federkraftklemmanschluss bzw. der zweite Federkraftklemmanschluss ohne zusätzliches Werkzeug betätigt werden kann. Die hiermit vorgeschlagene Hebelbetätigung macht die Verbindungsklemme anwenderfreundlicher und einfacher in der Bedienung.According to an advantageous development of the invention, it is provided that the connecting clamp has a first actuating lever for opening and closing the first spring-loaded terminal connection by acting on the clamping arm of the first clamping spring when the first actuating lever is actuated and / or a second actuating lever for opening and closing the second spring-loaded terminal connection by acting on the Has clamping leg of the second clamping spring when actuating the second actuating lever. This has the advantage that the first spring-loaded terminal connection or the second spring-loaded terminal connection can be actuated without additional tools. The proposed lever actuation makes the connection clamp more user-friendly and easier to use.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die erste und/oder die zweite Klemmfeder schlaufenförmig ausgebildet ist, wobei der jeweilige Anlageschenkel in einem verlängerten Endabschnitt der jeweiligen Klemmfeder in Richtung zur Stromschiene abgebogen ist. Dies hat den Vorteil, dass mit einer einstückig hergestellten Klemmfeder, die z.B. als Stanzbiegeteil hergestellt sein kann, die zuvor beschriebene Funktionalität des Federkraftklemmanschlusses sowie die Befestigung der Klemmfeder innerhalb der Verbindungsklemme realisiert werden kann.According to an advantageous development of the invention, it is provided that the the first and / or the second clamping spring is loop-shaped, the respective contact leg being bent in an extended end section of the respective clamping spring in the direction of the busbar. This has the advantage that the previously described functionality of the spring-loaded terminal connection and the fastening of the clamping spring within the connecting terminal can be realized with a one-piece clamping spring, which can be produced, for example, as a stamped and bent part.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die erste Klemmfeder die zweite Klemmfeder im Bereich ihrer jeweiligen Anlageschenkel berührt. Dies hat den Vorteil, dass sich die erste und die zweite Klemmfeder gegenseitig abstützen können, d.h. die eine Klemmfeder kann Druckkräfte der anderen Klemmfeder absorbieren. Auch hierdurch kann eine Materialeinsparung und ein kompaktes Design der Verbindungsklemme realisiert werden. Zudem wird die Belastung des Isolierstoffgehäuses durch Federkräfte minimiert, sodass das Isolierstoffgehäuse ebenfalls vereinfacht werden kann.According to an advantageous development of the invention, it is provided that the first clamping spring touches the second clamping spring in the region of its respective contact leg. This has the advantage that the first and second clamping springs can support each other, i.e. one clamping spring can absorb compressive forces of the other clamping spring. This also saves material and enables a compact design of the connecting terminal. In addition, the load on the insulating housing by spring forces is minimized, so that the insulating housing can also be simplified.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Anlageschenkel der ersten Klemmfeder einen Leiteranschlag beim Einführen des ersten Leiters in das Isolierstoffgehäuse und/oder der Anlageschenkel der zweiten Klemmfeder einen Leiteranschlag des zweiten Leiters beim Einführen in das Isolierstoffgehäuse bildet. Dies hat den Vorteil, dass keine zusätzlichen Maßnahmen zum Realisieren eines Leiteranschlags im jeweiligen Leitereinführbereich der Verbindungsklemme erforderlich sind, wie z.B. eine Isolierstoffwand. Auch hierdurch kann das Isolierstoffgehäuse hinsichtlich des notwendigen Materials und der Konstruktion optimiert werden. Durch den Leiteranschlag kann insbesondere ein zu weites Einführen des Leiters in die Verbindungsklemme vermieden werden. Für den Benutzer ist auf einfache Weise haptisch erkennbar, wenn ein Leiter ausreichend tief in die Verbindungsklemme eingeführt ist. Als Leiteranschlag kann z.B. der zuvor erwähnte in Richtung zur Stromschiene abgebogen Bereich der jeweiligen Klemmfeder dienen.According to an advantageous development of the invention, it is provided that the contact leg of the first clamping spring forms a conductor stop when the first conductor is inserted into the insulating material housing and / or the contact leg of the second clamping spring forms a conductor stop of the second conductor when it is inserted into the insulating material housing. This has the advantage that no additional measures are required to implement a conductor stop in the respective conductor insertion area of the connection terminal, such as an insulating wall. This also allows the insulating material housing to be optimized with regard to the necessary material and construction. The conductor stop in particular prevents the conductor from being inserted too far into the connecting terminal. The user can easily detect haptically when a conductor is inserted sufficiently deep into the connecting terminal. As a ladder stop, e.g. the area of the respective clamping spring which is bent in the direction of the busbar is used.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Durchgangsöffnung in der Stromschiene als Düsung (Materialdurchzug) ausgebildet ist. Die Düsung kann z.B. eine von der die Durchgangsöffnung umgebenden Oberfläche der Stromschiene abragende, die Durchgangsöffnung umgebende Wand aus dem Material der Stromschiene aufweisen. Dies hat den Vorteil, dass die Durchgangsöffnung auf einfache und bewährte Weise hergestellt werden kann. Zudem wird hierdurch eine mechanische Verstärkung der Stromschiene in dem durch die Durchgangsöffnung an sich geschwächten Bereich geschaffen. Auch die elektrischen Eigenschaften der Stromschiene werden verbessert.According to an advantageous development of the invention, it is provided that the Through opening in the busbar is designed as a nozzle (material passage). The nozzle can have, for example, a wall made of the material of the busbar, which wall projects from the surface of the busbar surrounding the busbar opening and surrounds the busbar opening. This has the advantage that the through opening can be produced in a simple and proven manner. In addition, this creates a mechanical reinforcement of the busbar in the area weakened by the through opening. The electrical properties of the busbar are also improved.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der in die Durchgangsöffnung eingehängte Bereich des Anlageschenkels der ersten Klemmfeder die Durchgangsöffnung der Stromschiene auf der von der ersten Klemmstelle abgewandten Seite der Stromschiene hintergreift und/oder der in die Durchgangsöffnung eingehängte Bereich des Anlageschenkels der zweiten Klemmfeder die Durchgangsöffnung der Stromschiene auf der von der zweiten Klemmstelle abgewandten Seite der Stromschiene hintergreift. Auf diese Weise kann die erste Klemmfeder und/oder die zweite Klemmfeder unterhalb der Stromschiene, d.h. an der von der jeweiligen Klemmstelle abgewandten Seite, darin eingehängt werden und wird ohne zusätzliche mechanische Fixiermittel an der Stromschiene sicher gehalten. Der in die Durchgangsöffnung eingehängte Bereich des Anlageschenkels der jeweiligen Klemmfeder kann z.B. die zuvor erwähnte Wand der Düsung hintergreifen.According to an advantageous development of the invention, it is provided that the area of the contact leg of the first clamping spring which is suspended in the through hole engages behind the passage opening of the busbar on the side of the busbar remote from the first clamping point and / or the area of the contact leg of the second clamping spring which is hooked into the through opening engages behind the through opening of the busbar on the side of the busbar facing away from the second clamping point. In this way, the first clamp spring and / or the second clamp spring can be located below the busbar, i.e. on the side facing away from the respective clamping point, are hung in and is held securely on the conductor rail without additional mechanical fixing means. The area of the contact leg of the respective clamping spring suspended in the through-opening can e.g. reach behind the aforementioned wall of the nozzle.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Anlageschenkel der ersten Klemmfeder an der Stromschiene auf deren der ersten Klemmstelle zugewandten Seite abgestützt ist und/oder der Anlageschenkel der zweiten Klemmfeder an der Stromschiene auf deren der zweiten Klemmstelle zugewandten Seite abgestützt ist. Auf diese Weise kann die Klemmfeder auf der anderen Seite der Stromschiene, auf der sie nicht die Durchgangsöffnung hintergreift, an der Stromschiene fixiert und dort sicher abgestützt werden. Dies kann z.B. dadurch realisiert werden, dass der Anlageschenkel der jeweiligen Klemmfeder in dem Bereich, in dem die Abstützung an der Stromschiene erfolgt, eine größere Breite aufweist als die Durchgangsöffnung.According to an advantageous further development of the invention, it is provided that the contact leg of the first clamping spring is supported on the busbar on its side facing the first clamping point and / or the contact leg of the second clamping spring is supported on the busbar on its side facing the second clamping point. In this way, the clamping spring on the other side of the busbar, on which it does not reach behind the through opening, can be fixed to the busbar and securely supported there. This can be achieved, for example, in that the contact leg of the respective clamping spring has a greater width in the region in which the support is provided on the busbar than the through opening.

Die erste und/oder die zweite Klemmfeder kann z.B. einen Federbogen aufweisen, über den der Anlageschenkel mit dem Klemmschenkel verbunden ist. Die Klemmfeder kann z.B. insgesamt V-förmig ausgebildet sein, z.B. in einer Art Schlaufenform.The first and / or the second clamping spring can e.g. have a spring arch, via which the contact leg is connected to the clamping leg. The clamping spring can e.g. overall be V-shaped, e.g. in a kind of loop shape.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die erste Klemmfeder und/oder die zweite Klemmfeder am Isolierstoffgehäuse abgestützt ist. Auf diese Weise kann die Klemmfeder zusätzlich im Isolierstoffgehäuse fixiert werden, z.B. in demjenigen Anlageschenkel-Bereich, der sich an einen Federbogen der Klemmfeder anschließt, über den der Anlageschenkel mit dem Klemmschenkel verbunden ist.According to an advantageous development of the invention, it is provided that the first clamping spring and / or the second clamping spring is supported on the insulating material housing. In this way, the clamping spring can also be fixed in the insulating housing, e.g. in the contact leg region which adjoins a spring arch of the clamping spring, via which the contact leg is connected to the clamping leg.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Verbindungsklemme an einer jeweiligen Gehäuseseite des Isolierstoffgehäuses mehrere nebeneinander angeordnete Leitereinführungsöffnungen aufweist, denen jeweils Federkraftklemmanschlüsse mit je einer einer Leitereinführungsöffnung zugeordneten Klemmfeder aufweisen, wobei verlängerte Endabschnitte nebeneinander angeordneter Klemmfedern in derselben Durchgangsöffnung der Stromschiene eingehängt sind. Eine solche Verbindungsklemme mit mehreren auf einer Gehäuseseite des Isolierstoffgehäuses nebeneinander angeordneten Leitereinführungsöffnungen wird auch als Doppelverbindungsklemme (bei zwei nebeneinander angeordneten Leitereinführungsöffnungen) oder Mehrfachverbindungsklemme (bei mehr als nebeneinanderliegenden Leitereinführungsöffnungen) bezeichnet. Durch die beschriebene Weiterbildung der Erfindung kann die Anzahl von zur Befestigung der Klemmfedern erforderlichen Durchgangsöffnungen in der Stromschiene minimiert werden, so dass eine Schwächung und Verschlechterung der elektrischen Eigenschaften der Stromschiene ebenfalls minimiert werden kann.According to an advantageous development of the invention, it is provided that the connecting terminal on a respective housing side of the insulating material housing has a plurality of conductor insertion openings arranged next to one another, each of which has spring-loaded terminal connections, each with a clamping spring assigned to a conductor insertion opening, with extended end sections of clamping springs arranged next to one another being suspended in the same through opening of the busbar. Such a connection terminal with a plurality of conductor entry openings arranged side by side on a housing side of the insulating material housing is also referred to as a double connection terminal (with two conductor entry openings arranged side by side) or multiple connection terminal (with more than side-by-side conductor entry openings). The described development of the invention can minimize the number of through openings in the busbar required for fastening the clamping springs, so that weakening and deterioration of the electrical properties of the busbar can also be minimized.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

In den Figuren werden gleiche Bezugszeichen für einander entsprechende Elemente verwendet.In the figures, the same reference numerals are used for corresponding elements.

Die in Figur 1 dargestellte Verbindungsklemme 9 ist bezüglich einer vertikalen Symmetrieachse im Wesentlichen symmetrisch aufgebaut. Sie weist jeweils links und rechts von der vertikalen Symmetrieachse einen ersten Federkraftklemmanschluss 1 und einen zweiten Federkraftklemmanschluss 2 auf. Die erste und der zweite Federkraftklemmanschluss 1, 2 sind in einem Isolierstoffgehäuse 4, 5 der Verbindungsklemme 9 angeordnet. Das Isolierstoffgehäuse 4, 5 kann z.B. wenigstens zweiteilig ausgebildet sein, z.B. aus einem Gehäuseoberteil 4 und einem durch Rastelemente 50 mit dem Gehäuseoberteil 4 verbindbaren Bodenteil 5.In the Figure 1 Connection terminal 9 shown is constructed essentially symmetrically with respect to a vertical axis of symmetry. It has a first spring clamp connection 1 and a second spring clamp connection 2 on the left and right of the vertical axis of symmetry. The first and the second spring terminal connection 1, 2 are arranged in an insulating material housing 4, 5 of the connecting terminal 9. The insulating material housing 4, 5 can be formed, for example, at least in two parts, for example from an upper housing part 4 and one bottom part 5 which can be connected to the upper housing part 4 by latching elements 50.

Der erste Federkraftklemmanschluss 1 weist eine schlaufenförmig mehrfach abgewinkelte erste Klemmfeder 11 auf. Die erste Klemmfeder 11 weist an einem Ende einen Klemmschenkel 12 auf, der zum Klemmen eines durch eine erste Leitereinführungsöffnung 10 eingeführten elektrischen Leiters gegen eine erste Klemmstelle 31 einer Stromschiene 3 dient. Im Bereich des Klemmschenkels 12 ist ein Beaufschlagungsbereich 13 der ersten Klemmfeder 11 vorhanden, an dem der Klemmschenkel 12 zum Öffnen und Schließen des ersten Federkraftklemmanschlusses 1 über einen Betätigungshebel 19 betätigt werden kann.The first spring-loaded terminal connection 1 has a first clamping spring 11, which is angled in multiple loops. The first clamping spring 11 has at one end a clamping leg 12 which is used to clamp an electrical conductor inserted through a first conductor insertion opening 10 against a first clamping point 31 of a busbar 3. In the area of the clamping leg 12 there is an action area 13 of the first clamping spring 11, on which the clamping leg 12 can be actuated via an actuating lever 19 for opening and closing the first spring-loaded terminal connection 1.

An den Klemmschenkel 12 der ersten Klemmfeder 11 schließt sich ein Federbogen 14 an, an den sich dann ein Anlageschenkel 15 der ersten Klemmfeder 11 anschließt. Der Anlageschenkel 15 liegt an einem inneren Wandbereich 41 des Isolierstoffgehäuses 4, 5 an und wird daran zumindest zum Teil gegenüber den vom Klemmschenkel 12 aufgenommenen Kräften abgestützt. Die erste Klemmfeder 11 erstreckt sich im Bereich des Anlageschenkels 15 weiter in einen verlängerten Endabschnitt 16, in dem das Material der ersten Klemmfeder 11 schließlich in einem Vertikalbereich 17 in Richtung zur Stromschiene 3 abgebogen ist. Der Endabschnitt 16 des Anlageschenkels 15 erstreckt sich über den Vertikalbereich 17 hinaus weiter nach unten durch eine Durchgangsöffnung 30 der Stromschiene 3 und ist schließlich in der Durchgangsöffnung 30 der Stromschiene 3 eingehängt, z.B. indem ein Endstück 18 des Endabschnitts 16 weiter abgewinkelt wird und damit die Stromschiene 3 hintergreift, insbesondere in einem als Düsung 33 ausgebildeten Bereich der Stromschiene 3, der die Durchgangsöffnung 30 sockelförmig umgibt.A spring arch 14 adjoins the clamping leg 12 of the first clamping spring 11, to which a contact leg 15 of the first clamping spring 11 then connects. The contact leg 15 lies against an inner wall region 41 of the insulating material housing 4, 5 and is supported on it at least in part with respect to the forces absorbed by the clamping leg 12. The first clamping spring 11 extends further in the region of the contact leg 15 into an extended end section 16, in which the material of the first clamping spring 11 is finally bent in a vertical region 17 in the direction of the busbar 3. The end section 16 of the contact leg 15 extends beyond the vertical region 17 further downward through a through opening 30 of the busbar 3 and is finally suspended in the through opening 30 of the busbar 3, e.g. in that an end piece 18 of the end section 16 is further angled and thus engages behind the busbar 3, in particular in a region of the busbar 3 designed as a nozzle 33, which surrounds the through opening 30 in a base shape.

Die zweite Klemmfeder 21 kann beispielsweise ebenso geformt sein wie die erste Klemmfeder 11. Hierfür ist vorgesehen, dass der zweite Federkraftklemmanschluss 2 eine schlaufenförmig mehrfach abgewinkelte zweite Klemmfeder 21 auf weist. Die zweite Klemmfeder 21 weist an einem Ende einen Klemmschenkel 22 auf, der zum Klemmen eines durch eine zweite Leitereinführungsöffnung 20 eingeführten elektrischen Leiters gegen eine zweite Klemmstelle 32 der Stromschiene 3 dient. Im Bereich des Klemmschenkels 22 ist ein Beaufschlagungsbereich 23 der zweiten Klemmfeder 21 vorhanden, an dem der Klemmschenkel 22 zum Öffnen und Schließen des zweiten Federkraftklemmanschlusses 2 über einen Betätigungshebel 29 betätigt werden kann.The second clamping spring 21 can, for example, be shaped in the same way as the first clamping spring 11. For this purpose, it is provided that the second spring-force clamping connection 2 has a second clamping spring 21 that is bent several times in a loop. The second clamping spring 21 has a clamping leg 22 at one end, which serves to clamp an electrical conductor inserted through a second conductor insertion opening 20 against a second clamping point 32 of the busbar 3. In the area of the clamping leg 22 there is an application area 23 second clamping spring 21 is present, on which the clamping leg 22 can be actuated via an actuating lever 29 for opening and closing the second spring-loaded clamping connection 2.

An den Klemmschenkel 22 der zweiten Klemmfeder 21 schließt sich ein Federbogen 24 an, an den sich dann ein Anlageschenkel 25 der zweiten Klemmfeder 21 anschließt. Der Anlageschenkel 25 liegt an einem inneren Wandbereich 42 des Isolierstoffgehäuses 4, 5 an und wird daran zumindest zum Teil gegenüber den vom Klemmschenkel 22 aufgenommenen Kräften abgestützt. Die zweite Klemmfeder 21 erstreckt sich im Bereich des Anlageschenkels 25 weiter in einen verlängerten Endabschnitt 26, in dem das Material der zweiten Klemmfeder 21 schließlich in einem Vertikalbereich 27 in Richtung zur Stromschiene 3 abgebogen ist. Der Endabschnitt 26 des Anlageschenkels 25 erstreckt sich über den Vertikalbereich 27 hinaus weiter nach unten durch die Durchgangsöffnung 30 der Stromschiene 3 und ist schließlich in der Durchgangsöffnung 30 der Stromschiene 3 eingehängt, z.B. indem ein Endstück 28 des Endabschnitts 26 weiter abgewinkelt wird und damit die Stromschiene 3 hintergreift, insbesondere in dem als Düsung 33 ausgebildeten Bereich der Stromschiene 3.A spring arch 24 adjoins the clamping leg 22 of the second clamping spring 21, to which a contact leg 25 of the second clamping spring 21 then connects. The contact leg 25 bears against an inner wall area 42 of the insulating material housing 4, 5 and is supported on it at least in part against the forces absorbed by the clamping leg 22. The second clamping spring 21 extends in the region of the contact leg 25 further into an extended end section 26, in which the material of the second clamping spring 21 is finally bent in a vertical region 27 in the direction of the busbar 3. The end section 26 of the contact leg 25 extends beyond the vertical region 27 further down through the through opening 30 of the busbar 3 and is finally suspended in the through opening 30 of the busbar 3, e.g. in that an end piece 28 of the end section 26 is further angled and thus engages behind the busbar 3, in particular in the region of the busbar 3 designed as a nozzle 33.

Die Figur 1 zeigt dabei den ersten Federkraftklemmanschluss 1 bei geöffnetem ersten Betätigungshebel 19, derart, dass die erste Klemmstelle 31 nicht vom Klemmschenkel 12 berührt wird und ein ggf. zuvor dort festgeklemmter elektrischer Leiter entnommen werden kann. Erkennbar ist, dass der Klemmschenkel 12 der ersten Klemmfeder 11 dann von der ersten Klemmstelle 31 entfernt ist. Der zweite Federkraftklemmanschluss 2 ist im geschlossenen Zustand dargestellt, d.h. der zweite Betätigungshebel 29 ist in der geschlossenen Stellung. In diesem Zustand berührt der Klemmschenkel 22 der zweiten Klemmfeder 21 endseitig die zweite Klemmstelle 32 der Stromschiene 3.The Figure 1 shows the first spring-loaded terminal connection 1 with the first actuating lever 19 open, such that the first clamping point 31 is not touched by the clamping leg 12 and an electrical conductor which may have been previously clamped there can be removed. It can be seen that the clamping leg 12 of the first clamping spring 11 is then removed from the first clamping point 31. The second spring-loaded terminal connection 2 is shown in the closed state, ie the second actuating lever 29 is in the closed position. In this state, the clamping leg 22 of the second clamping spring 21 touches the end of the second clamping point 32 of the busbar 3.

Erkennbar ist ferner, dass die Stromschiene 3 im Bereich ihrer ersten und zweiten Klemmstellen 31, 32 Einprägungen aufweist, durch die das Material der Stromschiene 3 nach oben hin, d.h. in Richtung zum jeweiligen Klemmschenkel 12, 22, etwas herausgestellt ist. Hierdurch wird die Klemmung eines angeschlossenen elektrischen Leiters verbessert.It can also be seen that the busbar 3 has embossments in the region of its first and second clamping points 31, 32, by means of which the material of the busbar 3 is exposed somewhat upwards, ie in the direction of the respective clamping leg 12, 22. This improves the clamping of a connected electrical conductor.

Die Stromschiene 3 ist einstückig als flachbauendes kurzes Stromschienenstück ausgebildet. Durch die Ausbildung der Durchgangsöffnung 30 mit der Düsung 33 wird die Stromschiene 3 in diesem Bereich mechanisch stabilisiert und zudem hinsichtlich der elektrischen Leitung optimiert.The busbar 3 is formed in one piece as a flat, short busbar piece. By designing the through opening 30 with the nozzle 33, the busbar 3 is mechanically stabilized in this area and also optimized with regard to the electrical line.

Die Montage der Verbindungsklemme 9 kann z.B. wie folgt durchgeführt werden:

  • Die Klemmfedern 11, 21 werden an der Stromschiene 3 montiert, die Klemmfedern 11, 21 können mit Dornen ausgelenkt werden;
  • Die Betätigungshebel 19, 29 können in einer Lage, die der geschlossenen Stellung entspricht, über die Anlageschenkel 15, 25 bis auf die Stromschiene 3 bewegt werden;
  • Die Klemmfedern 11, 21 werden durch Schwenken der Betätigungshebel 19, 29 in (vollständige) Offenstellung bewegt;
  • Ggf. genutzte Dorne werden zurückgezogen;
  • Die nun vormontierte Einheit mit Stromschiene 3, Klemmfedern 11, 21 und Betätigungshebeln 19, 29 (in Offenstellung) wird auf das auf Bodenteil 5 gesetzt;
  • Das Gehäuseoberteil 4 wird übergestülpt;
  • Die Betätigungshebel 19, 29 werden in die geschlossene Stellung geschwenkt.
The connection terminal 9 can be assembled as follows, for example:
  • The clamping springs 11, 21 are mounted on the busbar 3, the clamping springs 11, 21 can be deflected with thorns;
  • The actuating levers 19, 29 can be moved in a position which corresponds to the closed position, via the contact legs 15, 25 up to the busbar 3;
  • The clamping springs 11, 21 are moved by pivoting the actuating levers 19, 29 in the (full) open position;
  • Possibly. used mandrels are withdrawn;
  • The now pre-assembled unit with busbar 3, clamping springs 11, 21 and actuating levers 19, 29 (in the open position) is placed on the bottom part 5;
  • The upper housing part 4 is put over;
  • The actuating levers 19, 29 are pivoted into the closed position.

Die Klemmfedern 11, 21 können zunächst, d.h. bevor sie an der Stromschiene 3 befestigt sind, in ihren jeweiligen Endstücken 18, 28 noch nicht derart nach außen gebogen sein wie in Figur 1 erkennbar ist. Sie können zunächst im Wesentlichen gradlinig verlaufen. Nach Montage der Klemmfedern 11, 21 in der Durchgangsöffnung 30 der Stromschiene 3 erfolgt ein weiterer Fertigungsschritt, indem die Endstücke 18, 28 nach außen hin, d.h. in Richtung der jeweiligen Leitereinführungsöffnung 10, 20, gebogen werden und dann die Düsung 33 hintergreifen.The clamping springs 11, 21 cannot initially be bent outward in their respective end pieces 18, 28, ie before they are fastened to the busbar 3, as in FIG Figure 1 is recognizable. They can initially run essentially in a straight line. After the clamping springs 11, 21 have been installed in the through opening 30 of the busbar 3, a further production step takes place in that the end pieces 18, 28 are bent outwards, ie in the direction of the respective conductor insertion opening 10, 20, and then engage behind the nozzle 33.

Die erste Klemmfeder 11 ist dabei im Vertikalbereich 17 an dem Vertikalbereich 27 der zweiten Klemmfeder 21 abgestützt, d.h., die Klemmfedern 11, 21 stützen sich im Bereich ihrer Vertikalabschnitte 17, 27 gegenseitig ab. Der Vertikalbereich 17 bildet zudem einen Leiteranschlag beim Einführen des ersten Leiters in das Isolierstoffgehäuse. Der Vertikalbereich 27 bildet zudem einen Leiteranschlag beim Einführen des zweiten Leiters in das Isolierstoffgehäuse.The first clamping spring 11 is supported in the vertical region 17 on the vertical region 27 of the second clamping spring 21, ie the clamping springs 11, 21 are mutually supported in the region of their vertical sections 17, 27. The vertical region 17 also forms a conductor stop when the first conductor is inserted into the insulating housing. The vertical region 27 also forms a conductor stop when the second conductor is inserted into the insulating material housing.

Die Verbindungsklemme 9 kann als einfache Verbindungsklemme ausgebildet sein, bei der jeweils eine Leitereinführungsöffnung 10, 20 auf jeder Seite vorhanden ist. Sie kann auch als Zweifach- oder Mehrfachklemme ausgebildet sein. In diesem Fall sind auf jeder Seite zwei oder mehr erste Leitereinführungsöffnungen 10 und zwei oder mehr zweite Leitereinführungsöffnungen 20 jeweils nebeneinander angeordnet vorhanden. Für solche Ausführungsformen kann eine andere Ausgestaltung des jeweiligen Betätigungshebels 19, 29 vorteilhaft sein.The connecting clamp 9 can be designed as a simple connecting clamp, in which there is a conductor insertion opening 10, 20 on each side. It can also be designed as a double or multiple terminal. In this case, two or more first conductor insertion openings 10 and two or more second conductor insertion openings 20 are arranged side by side on each side. A different configuration of the respective actuating lever 19, 29 can be advantageous for such embodiments.

Die Figur 2 zeigt im unteren Bereich zunächst eine vorteilhafte Ausführungsform eines Betätigungshebels 6, der als erster oder zweiter Betätigungshebel 19, 29 eingesetzt werden kann, und zwar für den Fall, dass die Verbindungsklemme nur eine Leitereinführungsöffnung 10, 20 auf jeder Seite aufweist. Der Betätigungshebel 6 weist einen manuellen Betätigungsbereich 60 (Griffbereich) auf, an dem der Betätigungshebel 6 von einem Benutzer betätigt werden kann. Der Betätigungshebel 6 weist ferner eine Lagerungsachse 61 auf, über die er Isolierstoffgehäuse 4, 5 gelagert werden kann. Der Betätigungshebel 6 ist im Bereich der Lagerungsachse 61 gabelförmig ausgebildet, mit einem in der Mitte ausgesparten Bereich 65, mit dem der Betätigungshebel 6 über die dazwischenliegende Klemmfeder gestülpt werden kann. Die Klemmfeder weist dann seitlich hervorstehende Beaufschlagungsbereiche 13 bzw. 23 auf, an denen die Klemmfeder über Betätigungsbereiche 62 des Betätigungshebels 6 beaufschlagt werden kann. Eine rückwärtige Kontur des Betätigungshebels 6 weist zwei im Winkel zueinander angeordnete Lagerbereiche 63, 64 auf, über die der Betätigungshebel in dem Isolierstoffgehäuse und/oder an der Stromschiene 3 aufgelagert ist. In der geschlossenen Betätigungsstellung liegt der Betätigungshebel 6 mit dem Lagerbereich 63 auf, in der geöffneten Stellung mit dem Lagerbereich 64. Die Lagerungsachse 61 ist in einer im Wesentlichen senkrecht zur Stromschiene 3 ausgerichteten, im Gehäuseoberteil 4 angeordneten Nut (nicht dargestellt) aufgenommen, um eine durch die Lagerbereiche 63, 64, welche auf der Stromschiene 3 während der Schwenkbewegung des Betätigungshebels 19, 29 gleiten, bedingte während der Schwenkbewegung des Betätigungshebels19, 29 auftretende Auslenkung aufnehmen zu können.The Figure 2 shows in the lower area an advantageous embodiment of an actuating lever 6, which can be used as the first or second actuating lever 19, 29, in the event that the connecting terminal has only one conductor insertion opening 10, 20 on each side. The operating lever 6 has a manual operating area 60 (handle area), on which the operating lever 6 can be operated by a user. The actuating lever 6 also has a bearing axis 61, by means of which it can be used to mount insulating material housings 4, 5. The actuating lever 6 is fork-shaped in the region of the bearing axis 61, with a region 65 which is recessed in the middle and by means of which the actuating lever 6 can be placed over the clamping spring lying in between. The clamping spring then has laterally projecting areas 13 and 23, on which the clamping spring can be acted upon by actuating areas 62 of the actuating lever 6. A rear contour of the actuating lever 6 has two bearing regions 63, 64 arranged at an angle to one another, via which the actuating lever is supported in the insulating material housing and / or on the busbar 3. In the closed actuation position, the actuation lever 6 rests with the bearing area 63, in the open position with the bearing area 64. The bearing axis 61 is received in a groove (not shown) arranged in the housing upper part 4 and oriented essentially perpendicular to the busbar 3 through the bearing areas 63, 64 which are on the busbar 3 during the pivoting movement of the actuating lever 19, 29 to be able to accommodate conditional deflection occurring during the pivoting movement of the actuating lever 19, 29.

Die Figur 2 zeigt im oberen Bereich eine Ausführung eines Betätigungshebels 6, der für eine Verbindungsklemme ausgebildet ist, bei der zwei nebeneinander angeordnete Federkraftklemmanschlüsse je Gehäuseseite vorhanden sind. Dementsprechend ist der gesamte Betätigungshebel 6 breiter ausgebildet und weist zwei nebeneinanderliegende, ausgesparte Bereiche 65 auf, in denen jeweilige Klemmfedern hindurchgeführt werden können. Entsprechende sind drei Beaufschlagungsbereiche 62 vorgesehen. Hierbei wirkt der mittlere Beaufschlagungsbereich 62 gleichzeitig auf die beiden benachbarten Klemmfedern an einer Seite der Verbindungsklemme 9 ein.The Figure 2 shows in the upper area an embodiment of an actuating lever 6, which is designed for a connecting terminal, in which there are two spring-loaded terminal connections arranged side by side on each housing side. Accordingly, the entire actuating lever 6 is made wider and has two recessed areas 65 lying next to one another, in which respective clamping springs can be passed. Correspondingly, three areas of application 62 are provided. Here, the middle loading area 62 acts simultaneously on the two adjacent clamping springs on one side of the connecting terminal 9.

Die Figur 3 zeigt in vergrößerter Detaildarstellung die Befestigung der Klemmfedern an der Stromschiene 3. Beispielhaft dargestellt ist eine doppelte Klemmfeder, die zwei nebeneinander verlaufende Anlageschenkel und Klemmschenkel aufweist und somit für eine Verbindungsklemme ausgebildet ist, bei der zwei nebeneinander angeordnete Federkraftklemmanschlüsse je Gehäuseseite vorhanden sind. Dargestellt ist hier ein Teilabschnitt der jeweiligen Vertikalbereiche 27 der Klemmfedern. Diese vereinen sich dann zu einem gemeinsamen Befestigungsabschnitt 271, der schließlich über die Endstücke 28, die durch die Durchgangsöffnung 30 geführt sind, an der Düsung 33 der Stromschiene 3 befestigt ist. Beispielhaft ist dargestellt, dass das linke Endstück 28 bereits umgebogen ist, wie in Figur 1 dargestellt, und das rechte Endstück 28 noch nicht umgebogen ist.The Figure 3 shows in an enlarged detail the attachment of the clamping springs on the busbar 3. An example is shown a double clamping spring, which has two juxtaposed contact legs and clamping legs and is thus designed for a connecting clamp, in which there are two spring-cage clamp connections arranged next to each other on the housing side. A partial section of the respective vertical regions 27 of the clamping springs is shown here. These then unite to form a common fastening section 271, which is finally fastened to the nozzle 33 of the busbar 3 via the end pieces 28 which are guided through the through opening 30. It is shown as an example that the left end piece 28 has already been bent over, as in FIG Figure 1 shown, and the right end piece 28 is not yet bent.

An der Oberseite der Stromschiene 3, d.h. der der jeweiligen Klemmstelle 31, 32 zugewandten Seite der Stromschiene 3, liegt die Klemmfeder mit Auflageflächen 270 auf der Stromschiene 3 auf.At the top of the busbar 3, i.e. On the side of the busbar 3 facing the respective clamping point 31, 32, the clamping spring rests on the busbar 3 with contact surfaces 270.

Die Figur 4 zeigt in vergrößerter Detaildarstellung eine mögliche Formgebung der Stromschiene 3 im Bereich der Durchgangsöffnung 30. Die Durchgangsöffnung 30 muss z.B. nicht kreisrund sein, sondern kann, wie dargestellt, im Wesentlichen rechteckförmig mit abgerundeten Ecken ausgebildet sein. Dementsprechend umrandet der Wandbereich der Düsung 33 diese Durchgangsöffnung 30.The Figure 4 shows an enlarged detail view of a possible shape of the busbar 3 in the area of the passage opening 30. The passage opening 30 does not have to be circular, for example, but can, as shown, essentially be rectangular with rounded corners. Accordingly, the wall area of the nozzle 33 surrounds this through opening 30.

Die Doppelverbindungsklemme 9 gemäß den Figuren 5 bis 9 entspricht in ihrem wesentlichen Aufbau der bisher anhand der Figuren 1 bis 4 erläuterten Verbindungsklemme 9. Daher soll nachfolgend im Wesentlichen auf die Unterschiede eingegangen werden.The double connection terminal 9 according to the Figures 5 to 9 corresponds in its essential structure to that previously based on the Figures 1 to 4 explained connection terminal 9. Therefore, the differences are essentially discussed below.

Wie die Figur 5 zeigt, sind bei der Doppelverbindungsklemme 9 an jeder Leitereinführseite jeweils zwei nebeneinander liegende Leitereinführungsöffnungen 10, 20 vorhanden. In der geschlossenen Stellung sind beim Blick in die Leitereinführungsöffnungen 20 beispielsweise die Klemmschenkel 22 sichtbar. Die Figur 6 zeigt einen vergleichbar ausgebildeten Betätigungshebel 6, wie in Figur 2 in der oberen Abbildung dargestellt. Der Betätigungshebel gemäß Figur 6 kann als Betätigungshebel 19 und 29 angesetzt werden, wie in der Figur 7 ersichtlich ist.As the Figure 5 shows, there are two adjacent conductor insertion openings 10, 20 in each case at the double connection terminal 9 on each conductor insertion side. In the closed position, for example, the clamping legs 22 are visible when looking into the conductor insertion openings 20. The Figure 6 shows a comparable operating lever 6, as in Figure 2 shown in the figure above. The operating lever according to Figure 6 can be used as an operating lever 19 and 29, as in the Figure 7 can be seen.

Im Unterschied zu der anhand der Figuren 1 bis 4 erläuterten Ausführungsform weist bei der nun erläuterten Doppelverbindungsklemme 9 die Stromschiene 3 weiterhin eine Durchgangsöffnung 30 auf, die jedoch hier ohne die Düsung 33 ausgebildet ist. Durch die Durchgangsöffnung 30 ragen auch bei dieser Ausführungsform die Vertikalbereiche 17, 27 der Endabschnitte 16, 26 der Klemmfedern 11, 21. Die Vertikalbereiche 17, 27 enden aber nicht wie bei der zuerst erläuterten Ausführungsform in weiter abgewinkelten Endstücken 18, 28. Stattdessen verlaufen sie in geraden Endstücken 71, 72 weiter in vertikaler Richtung. Um die Fixierung der Klemmfedern 11, 21 in der Öffnung 30 der Stromschiene 3 zu realisieren, sind an den Endstücken 71, 72 jeweilige, im Sinne einer Rastnase oder eines Widerhakens herausgestellte Materialbereiche 73, 74 vorhanden. Die Materialbereiche 73, 74 sind federelastisch auslenkbar, so dass die Klemmfedern 11, 21 in der dargestellten Rücken-an-Rücken-Konfiguration mit den Endstücken 71, 72 durch die Öffnungen 30 der Stromschiene 3 gesteckt werden können. Beim Durchstecken federn die Materialbereiche 73, 74 zunächst ein. Ist dieser Steckvorgang durchgeführt, federn die Materialbereiche 73, 74 wieder aus und Hintergreifen die Stromschiene 3 und fixieren damit die Klemmfedern 11, 21 an der Stromschiene 3.In contrast to that based on the Figures 1 to 4 In the illustrated embodiment, in the double connection terminal 9 now explained, the busbar 3 also has a through opening 30 which, however, is formed here without the nozzle 33. The vertical regions 17, 27 of the end sections 16, 26 of the clamping springs 11, 21 also protrude through the through opening 30 in this embodiment. However, the vertical regions 17, 27 do not end in further angled end pieces 18, 28 as in the embodiment explained first. Instead, they run in straight end pieces 71, 72 further in the vertical direction. In order to fix the clamping springs 11, 21 in the opening 30 of the busbar 3, respective material areas 73, 74, which are exposed in the sense of a latch or barb, are provided on the end pieces 71, 72. The material areas 73, 74 can be deflected resiliently, so that the clamping springs 11, 21 in the illustrated back-to-back configuration with the end pieces 71, 72 can be inserted through the openings 30 of the busbar 3. When pushing through, the material areas 73, 74 initially deflect. If this plug-in process is carried out, the material areas 73, 74 spring out again and engage behind the busbar 3 and thus fix the clamping springs 11, 21 on the busbar 3.

Wie in der Figur 7 erkennbar ist, ist es bei dieser Ausführungsform auch nicht erforderlich, dass die Anlageschenkel 15, 25 an Wandbereichen des Isolierstoffgehäuses 4, 5 anliegen oder sich daran abstützen. Stattdessen kann eine freitragende Konstruktion der Klemmfedern 11, 21 realisiert werden.Like in the Figure 7 is recognizable, it is also not necessary in this embodiment that the contact legs 15, 25 rest against or are supported on wall areas of the insulating material housing 4, 5. Instead, a self-supporting construction of the clamping springs 11, 21 can be realized.

Grundsätzlich ist es möglich, dass jede Klemmfeder 11 ein eigenes Endstück 71, 72 mit einem herausgestellten Materialbereich 73, 74 aufweist. Bei einer Einzel-Verbindungsklemme ist dies auch erforderlich. Bei der hier beschriebenen Doppelverbindungsklemme 9 kann dies ebenfalls so realisiert werden, so dass die Klemmfedern unabhängig voneinander durch jeweils eigene Endstücke 71, 72 mit daran angeordneten abragenden Materialbereichen 73, 74 ausgebildet sind.In principle, it is possible for each clamping spring 11 to have its own end piece 71, 72 with an exposed material area 73, 74. This is also necessary for a single connection terminal. With the double connection clamp 9 described here, this can also be implemented in such a way that the clamping springs are formed independently of one another by their own end pieces 71, 72 with projecting material areas 73, 74 arranged thereon.

Alternativ können nebeneinander liegende, benachbarte Klemmfedern auch über ein gemeinsames Endstück 71 bzw. 72 mit jeweils einem hervorstehenden Materialbereich 73 bzw. 74 ausgebildet sein. In diesem Fall können die Vertikalbereiche 17, 27 jeweils breiter ausgebildet sein, so dass sie durchgehend von der einen zur daneben angeordneten anderen Klemmfeder reichen.Alternatively, adjacent clamping springs lying next to one another can also be formed via a common end piece 71 or 72, each with a protruding material region 73 or 74. In this case, the vertical regions 17, 27 can each be made wider, so that they extend continuously from one to the other arranged clamping spring.

Dies ist anhand der Figuren 8 und 9 zusätzlich verdeutlicht, in denen der durch die Stromschiene 3 und die Klemmfedern 11, 21 gebildete Kontakteinsatz separat dargestellt ist. Wie man erkennt, sind jeweils zwei nebeneinander angeordnete Klemmfedern 11 bzw. 21 über einen gemeinsamen, in der Breite durchgehenden Vertikalbereich 17 bzw. 27 miteinander verbunden und darüber an der Stromschiene 3 befestigt. Jeder Vertikalbereich 17, 27 weist, z. B. an zentraler Stelle, das genannte, durch die Durchgangsöffnung 30 der Stromschiene 3 hindurchgesteckte Endstück 71 bzw. 72 mit dem daran angeordneten, zur Fixierung dienenden herausgestellten Materialbereich 73 bzw. 74 auf.This is based on the Figures 8 and 9 additionally clarifies in which the contact insert formed by the busbar 3 and the clamping springs 11, 21 is shown separately. As can be seen, two clamping springs 11 and 21, which are arranged next to one another, are connected to one another via a common vertical region 17 and 27, which is continuous in width, and are fastened to the busbar 3. Each vertical region 17, 27 has, for. B. at a central point, the mentioned, through the through opening 30 of the busbar 3 end piece 71 or 72 with the arranged, serving for fixing exposed material area 73 or 74 on.

Die nebeneinander angeordneten Klemmfedern 11 bzw. 21 sind unabhängig voneinander betätigbar, d. h. sie sind in den übrigen Bereichen, jenseits der gemeinsamen Vertikalbereiche 17 bzw. 27, nicht miteinander verbunden.The side-by-side clamping springs 11 and 21 can be actuated independently of one another, i. H. they are not connected to one another in the other areas, beyond the common vertical areas 17 and 27.

Die erfindungsgemäße Verbindungsklemme oder Doppelverbindungsklemme 9 kann auch als Mehrfachverbindungsklemme ausgebildet sein, bei der mehr als zwei nebeneinander angeordnete Klemmstellen an jeder Leitereinführseite vorhanden sind, z. B. 3, 4, 5 oder mehr. Hierbei kann jeweils für Gruppen von Klemmfedern oder für sämtliche Klemmfedern zu deren Fixierung an der Stromschiene eine gemeinsame Durchgangsöffnung in der Stromschiene vorhanden sein.The connection terminal or double connection terminal 9 according to the invention can also be designed as a multiple connection terminal, in which there are more than two juxtaposed clamping points on each conductor insertion side, z. B. 3, 4, 5 or more. In this case, a common through opening can be present in the conductor rail for groups of clamping springs or for all the clamping springs for fixing them to the conductor rail.

Die Figur 10 zeigt eine Ansicht auf die Unterseite des Gehäuseoberteils 4 der Doppelverbindungsklemme 9, d.h. auf die Seite, an der das Gehäuseunterteil anmontiert wird. Die Figur 11 zeigt das Gehäuseoberteil 4 gemäß der in Figur 10 dargestellten Schnittebene B-B der Doppelverbindungsklemme. Erkennbar sind insbesondere in den Seitenwänden angeordnete Nuten 41, 42 zur Aufnahme und Lagerung der Betätigungshebel 19, 29, welche mit ihren Lagerungsachsen 61 jeweils von unten in die Nuten 41, 42 eingeschoben werden können, um dann am oberen Ende der jeweiligen Nut 41, 42 gelagert und gehalten zu werden. Die jeweiligen Nuten 41, 42 erstrecken sich von der Unterseite des Gehäuseoberteils 4 hin bis zu einer Position oberhalb der jeweiligen Leitereinführungsöffnung 10, 20.The Figure 10 shows a view of the underside of the upper housing part 4 of the double connection terminal 9, ie to the side on which the lower housing part is mounted. The Figure 11 shows the upper housing part 4 according to the in Figure 10 shown section plane BB of the double connection terminal. In particular, grooves 41, 42 can be seen in the side walls for receiving and mounting the actuating levers 19, 29, each of which can be inserted with their bearing axes 61 into the grooves 41, 42 from below, and then at the upper end of the respective groove 41, 42 to be stored and kept. The respective grooves 41, 42 extend from the underside of the upper housing part 4 to a position above the respective conductor insertion opening 10, 20.
