Description

Die Erfindung betrifft eine Leiteranschlussklemme mit einem Isolierstoffgehäuse, das eine Leitereinführungsöffnung zum Einführen eines elektrischen Leiters und eine Kontaktstift-Einführöffnung zum Einführen eines Kontaktstiftes hat, mit einer Klemmfeder, die einen Klemmschenkel, einen Federbogen und einen Anlageschenkel hat, und mit einem Stromschienenstück, das eine Durchgangsöffnung zur Aufnahme des Kontaktstiftes hat und zum Anklemmen des elektrischen Leiters zwischen den Klemmschenkel und einem Quersteg des Stromschienenstücks ausgebildet ist.The invention relates to a conductor terminal with an insulating material housing, which has a conductor insertion opening for insertion of an electrical conductor and a contact pin insertion opening for inserting a contact pin, with a clamping spring, which has a clamping leg, a spring bow and a plant leg, and with a busbar piece, the one Through opening for receiving the contact pin and is designed to clamp the electrical conductor between the clamping legs and a crosspiece of the busbar piece.

Leiteranschlussklemmen zum Anklemmen elektrischer Leiter mittels Federkraft unter Verwendung einer Klemmfeder sind hinlänglich bekannt. Als Klemmfedern werden insbesondere Käfigzugfedern oder Schenkelfedern eingesetzt. Davon zu unterscheiden sind Federkraftklemmen mit Schraubenfedern, die insbesondere für den Hochstrombereich eingesetzt werden.Conductor terminals for clamping electrical conductors by means of spring force using a clamping spring are well known. Cage tension springs or torsion springs are used in particular as clamping springs. This should be distinguished from spring-loaded terminals with coil springs, which are used in particular for the high current range.

Zusätzlich zu dem Anklemmen eines elektrischen Leiters ist oftmals erforderlich, einen Kontaktstift als Steckkontakt an den Federkraftklemmanschluss mit anzuschließen.In addition to the clamping of an electrical conductor is often necessary to connect a contact pin as a plug contact to the Federkraftklemmanschluss.

DE 10 2008 049 236 B3 und DE 10 2013 101 533 A1 zeigen Federkraftklemmen mit einer Schenkelfeder oder einer Käfigzugfeder, die an einem Stromschienenstück aufgehängt sind und zusammen mit dem Stromschienenstück eine Klemmstelle zum Anklemmen eines elektrischen Leiters bilden. Eine Verlängerung des Stromschienenstücks ist unter Bildung eines Klemmschlitzes zur Steckkontaktierung eines Kontaktstiftes geschlitzt. Das Stromschienenstück stellt somit an seinem Klemmschlitz einen Klemmkontakt für einen Kontaktstift bereit. DE 10 2008 049 236 B3 and DE 10 2013 101 533 A1 show spring terminals with a leg spring or a cage spring, which are suspended on a busbar piece and together with the busbar piece form a terminal point for clamping an electrical conductor. An extension of the busbar piece is slotted to form a clamping slot for plug contacting a contact pin. The busbar piece thus provides a clamping contact for a contact pin at its clamping slot.

DE 10 2010 010 260 A1 zeigt einen Steckverbinder mit einer in ein Stromschienenstück eingehängten Schenkelfeder und einem Isolierstoffgehäuse, das an der Leitereinführungsöffnung an der Oberseite und an dem gegenüberliegenden Boden eine Kontaktstift-Einführöffnung zur Aufnahme eines Kontaktstiftes hat. Der Kontaktstift wird durch einen Durchbruch in dem Stromschienenstück geführt, in den auch der Anlageschenkel der Schenkelfeder eintaucht. Damit wird der Kontaktstift durch die Federkraft des Anlageschenkels der Schenkelfeder an einen den Durchbruch der Stromschienenstücks begrenzenden Quersteg angeklemmt. Der elektrische Leiter wird auf der gegenüberliegenden Seite der Schenkelfeder mit einer Klemmkante am freien Ende des Klemmschenkels an eine Kontaktkante des Stromschienenstücks angeklemmt, die eine Leiterdurchführungsöffnung im Stromschienenstück stirnseitig begrenzt. DE 10 2010 010 260 A1 shows a connector with a leg spring suspended in a bus bar piece and an insulating housing having a contact pin insertion opening for receiving a contact pin at the conductor insertion opening at the top and at the opposite bottom. The contact pin is guided by a breakthrough in the conductor rail piece, in which also the Plant leg of the leg spring dips. Thus, the contact pin is clamped by the spring force of the contact leg of the leg spring to a breakthrough of the busbar piece limiting cross bar. The electrical conductor is clamped on the opposite side of the leg spring with a clamping edge at the free end of the clamping leg to a contact edge of the busbar piece, which limits a conductor lead-through opening in the busbar piece frontally.

Weiterhin ist aus DE 20 2011 102 996 U1 ein Federkraftklemmkontakt mit einem Stromschienenelement und mit einer Klemmfeder bekannt. Der Federbogen der Klemmfeder hat sich in Längserstreckungsrichtung des Federblechs erstreckende Materialvertiefungen oder das Federblech vollständig durchdringende Schlitze. Damit wird die Federwirkung des Biegeradius der Klemmfeder erhöht und die Eigenschaften der Klemmfeder werden verbessert.Furthermore, it is off DE 20 2011 102 996 U1 a spring force clamping contact with a busbar element and with a clamping spring known. The spring bow of the clamping spring has extending in the longitudinal direction of the spring plate material recesses or the spring plate completely penetrating slots. Thus, the spring action of the bending radius of the clamping spring is increased and the properties of the clamping spring are improved.

US 2011/0217882 A1 lehrt eine Leiteranschlussklemme mit einem Stromschienenstück, wobei das Stromschienenstück eine Öffnung zwischen zwei Klemmarmen zum Einstecken und Anklemmen eines Kontaktstiftes hat. US 2011/0217882 A1 teaches a conductor terminal with a bus bar piece, the conductor bar piece having an opening between two clamping arms for inserting and clamping a contact pin.

DE 202 10 105 U1 discloses a spring force clamping connection, wherein the spring force clamping connection has a bus bar, in which a steel spring is suspended.

Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, eine möglichst kompakte Leiteranschlussklemme mit selbsttragendem, aus Klemmfeder und Stromschienenstück gebildeten Federkraftklemmanschluss bereitzustellen, bei dem sowohl ein elektrischer Leiter, als auch ein Kontaktstift zuverlässig an dem Federkraftklemmanschluss unabhängig voneinander angeklemmt werden können. Dabei soll es möglich sein, einen elektrischen Leiter vor Einstecken eines Kontaktstiftes anzuklemmen und umgekehrt.Based on this, it is an object of the present invention to provide a compact conductor terminal as possible with self-supporting, formed of spring clip and busbar piece spring terminal connection, in which both an electrical conductor, and a pin can be reliably clamped to the Federkraftklemmanschluss independently. It should be possible to clamp an electrical conductor before inserting a contact pin and vice versa.

Die Aufgabe wird mit der Leiteranschlussklemme mit dem Merkmal des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen beschrieben.The object is achieved with the conductor terminal with the feature of claim 1. Advantageous embodiments are described in the subclaims.

Für eine gattungsgemäße Leiteranschlussklemme wird vorgeschlagen, dass die Durchgangsöffnung im Stromschienenstück auf der dem Quersteg gegenüberliegender Seite einen Durchbruch am freien Ende des Stromschienenstücks aufweist. Das Stromschienenstück ist mit Hilfe dieses Durchbruchs an seinem freien, dem Querschnitt gegenüberliegendem Ende somit geöffnet bzw. geschlitzt, so dass die hierdurch entstehenden Seitenstege quer zur Längserstreckungsrichtung des Stromschienenstücks aufeinander zu beweglich sind.For a generic conductor connection terminal is proposed that the passage opening in the conductor rail piece on the side opposite the crosspiece has an opening at the free end of the conductor rail piece. The busbar piece is thus opened or slotted with the aid of this opening at its free, opposite cross-section end, so that the resulting side webs are movable toward each other transversely to the longitudinal direction of the busbar piece.

Der Anlageschenkel der Klemmfeder hat zwei voneinander beabstandete Federarme, die das Stromschienenstück im Bereich des Durchbruchs beidseits umgreifen und eine Federkraft-Klemmstelle zum Einklemmen eines in die Durchgangsöffnung im Bereich des Durchbruchs eingesteckten Kontaktstiftes in das Stromschienenstück mit der Federkraft der Federarme des Anlageschenkels bilden. Mit Hilfe des Durchbruchs und der hierdurch bewirkten Relativ-Beweglichkeit der Durchgangsöffnung und den Durchbruch begrenzenden Seitenstege des Stromschienenstücks werden diese Seitenstege mit Hilfe der diese umgreifenden Federarme mit einer Federkraft beaufschlagt, um einen Federkraft-Klemmanschluss für einen in die Durchgangsöffnung oder den Durchbruch eingesteckten Kontaktstift bereitzustellen. Der Kontaktstift kann dabei im Bereich des Durchbruchs, d.h. in dem Durchbruch oder benachbart zum Durchbruch in die Durchgangsöffnung eingesteckt und mittels der Federkraft steckkontaktiert werden.The plant leg of the clamping spring has two spaced apart spring arms which surround the busbar piece in the region of the opening on both sides and form a spring force clamping point for clamping a plugged into the through hole in the region of the opening pin in the busbar piece with the spring force of the spring arms of the plant leg. With the help of the breakthrough and the resulting relative mobility of the through hole and the breakthrough limiting side webs of the busbar piece these side bars are acted upon by the spring arms embracing them with a spring force to provide a spring force terminal connection for a plugged into the through hole or the opening pin , The contact pin can in the area of the breakthrough, i. inserted in the opening or adjacent to the breakthrough in the passage opening and plug-contacted by means of the spring force.

Diese Leiteranschlussklemme kann ein- oder mehrpolig mit einem oder mehreren Federkraftklemmanschlüssen mit zugehörigen Leitereinführungsöffnungen und Kontakt-Einführungsöffnungen im Isolierstoffgehäuse ausgeführt sein. Der Begriff "ein" ist somit nicht als Zahlwort zu verstehen, sondern im Sinne von "mindestens ein".This conductor terminal may be single or multi-pole with one or more Federerkraftklemmanschlüssen with associated conductor insertion openings and contact insertion openings in the insulating material. The term "a" is therefore not to be understood as a number word, but in the sense of "at least one".

Der elektrische Leiter wird dabei mit dem Klemmschenkel der Klemmfeder an dem Quersteg angeklemmt, der dem Durchbruch und dem Federarm am Anlageschenkel der Klemmfeder diametral gegenüberliegt.The electrical conductor is clamped to the clamping leg of the clamping spring on the cross bar, which is diametrically opposite to the opening and the spring arm on the plant leg of the clamping spring.

Mit dieser Lösung gelingt nicht nur eine optimale Ausnutzung einer zusätzlichen Federklemmkraft durch die Ausbildung eines Federklemmelements am Anlageschenkel, das quer zur Erstreckungsrichtung zur Anlageschenkels wirkt. Vielmehr wird auch der verfügbare Bauraum unterhalb des Federbogens optimal zur Aufnahme des Kontaktstiftes genutzt. Damit kann die Bauhöhe der Leiteranschlussklemme gering gehalten werden. Mit Hilfe der quer zur Erstreckungsrichtung der Anlageschenkel wirkenden Federarme am Anlageschenkel hat die Klemmung eines Kontaktstiftes keine oder nur eine vernachlässigbare Rückwirkung auf die Klemmung des elektrischen Leiters mit Hilfe des Klemmschenkels. Die Klemmkräfte oder Kontaktkräfte für den elektrischen Leiter und den Kontaktstift sind somit unabhängig voneinander.With this solution, not only an optimal utilization of an additional spring clamping force by the formation of a spring clamping element on the plant limb, which acts transversely to the extension direction to the plant leg. Rather, the available space below the spring bow is used optimally for receiving the contact pin. Thus, the height of the conductor terminal can be kept low. With the help of acting transversely to the extension direction of the plant leg spring arms on the plant leg, the clamping of a contact pin has no or only a negligible effect on the clamping of the electrical conductor by means of the clamping leg. The clamping forces or contact forces for the electrical conductor and the contact pin are thus independent of each other.

Besonders vorteilhaft ist es, wenn der Anlageschenkel in Erstreckungsrichtung des Anlageschenkels ausgehend von den Federarmen zu dem Federbogen hin geschlitzt ist. Damit ist nicht nur zwischen den Federarmen ein Freiraum im Anlageschenkel vorhanden. Vielmehr geht dieser Freiraum in einen Schlitz über, der die Federkraft des Anlageschenkels quer zur Erstreckungsrichtung des Anlageschenkels vergrößert. Der Schlitz erstreckt sich vorzugsweise in den Federbogen hinein. Damit wird die verfügbare Federarmlänge vergrößert und damit die resultierende Federcharakteristik verbessert. Zudem wird durch den geschlitzten Federbogen auch die Federwirkung des Biegeradius der Klemmfeder und damit die Federcharakteristik des Klemmschenkels verbessert.It is particularly advantageous if the bearing limb is slotted in the extension direction of the bearing limb starting from the spring arms towards the spring bow. This is not only between the spring arms a space in the plant leg available. Rather, this space is in a slot, which increases the spring force of the abutment leg transversely to the direction of extension of the plant leg. The slot preferably extends into the spring bow. This increases the available spring arm length and thus improves the resulting spring characteristic. In addition, the spring action of the bending radius of the clamping spring and thus the spring characteristic of the clamping leg is improved by the slotted spring bow.

In einer vorteilhaften Ausführungsform taucht das freie Ende des Klemmschenkels der Klemmfeder zumindest im Zustand ohne angeklemmten elektrischen Leiter durch die Durchgangsöffnung hindurch. Damit wird erreicht, dass der Klemmschenkel in der Ruheposition ohne eingesteckten elektrischen Leiter am Quersteg des Stromschienenstücks gehalten wird. Zudem kann hierdurch erreicht werden, dass die Klemmkraft der Klemmfeder optimal auf den Quersteg konzentriert wird, um die Flächenpressung zu erhöhen. Durch diese Ausbildung wird zudem sichergestellt, dass die Litzen eines flexiblen elektrischen Leiters in der Durchgangsöffnung sicher gehalten werden können.In an advantageous embodiment, the free end of the clamping leg of the clamping spring immersed at least in the state without clamped electrical conductor through the through hole. This ensures that the clamping leg is held in the rest position without plugged electrical conductors on the crossbar of the busbar piece. In addition, this can be achieved by the fact that the clamping force of the clamping spring is optimally concentrated on the crossbar in order to increase the surface pressure. This design also ensures that the strands of a flexible electrical conductor can be securely held in the passage opening.

Der Kontaktstift ist vorzugsweise in einen Freiraum der Klemmfeder auf der von dem Anlageschenkel aufgespannten Ebene zwischen den Federarmen einführbar. Bei dieser Variante wird somit die von dem Anlageschenkel aufgespannte Ebene genutzt, um den Kontaktstift aufzunehmen. Hierzu dient der die Federarme bildende Freiraum zwischen den Federarmen, der über die erforderliche Stecklänge ausreichend breit sein muss, um den Kontaktstift zwischen den Federarmen aufzunehmen. Eine Alternative ist das Einstecken des Kontaktstiftes zwischen dem Quersteg bzw. der Klemmkante des Klemmschenkels und dem Anlageschenkel benachbart zu dem Anlageschenkel derart, dass der Kontaktstift neben dem Anlageschenkel unterhalb des Federbogens in den dortigen Freiraum eintaucht.The contact pin is preferably inserted into a free space of the clamping spring on the plane defined by the plant leg plane between the spring arms. In this variant, thus, the plane spanned by the plant leg is used, to pick up the contact pin. For this purpose, the spring arms forming free space between the spring arms, which must be sufficiently wide over the required insertion length to accommodate the contact pin between the spring arms. An alternative is the insertion of the contact pin between the transverse web or the clamping edge of the clamping leg and the bearing leg adjacent to the plant leg such that the contact pin immersed next to the plant leg below the spring bow in the local space.

Vorteilhaft ist es, wenn der Quersteg, der die Durchgangsöffnung begrenzt und zum Anklemmen eines elektrischen Leiters mit der Klemmkante des Klemmschenkels vorgesehen ist, quer zu der von der Durchgangsöffnung aufgespannten Ebene abgebogen ist. Damit wird eine Leiterführungswand geschaffen. Zudem kann die Klemmstelle für den elektrischen Leiter an dem Quersteg aus der Ebene der Durchgangsöffnung heraus in Leitereinsteckrichtung nach oben oder unten verlagert werden. Damit kann der Quersteg bzw. dessen Klemmkante optimal an die Klemmfeder und die konstruktiven Steckbedingungen zum Anklemmen eines elektrischen Leiters angepasst werden.It is advantageous if the transverse web, which delimits the passage opening and is provided for clamping an electrical conductor to the clamping edge of the clamping leg, is bent transversely to the plane spanned by the passage opening. For a ladder guide wall is created. In addition, the clamping point for the electrical conductor can be displaced on the transverse web out of the plane of the passage opening in Leitereinsteckrichtung up or down. Thus, the cross bar or its clamping edge can be optimally adapted to the clamping spring and the constructive plug conditions for clamping an electrical conductor.

Der Kontaktstift ist vorteilhafterweise in einem Isolierstoffsockel aufgenommen. Der Isolierstoffsockel hat dabei einen zum Eintauchen in die Durchgangsöffnung des Stromschienenstücks ausgebildeten Finger. Somit wird nicht nur der Kontaktstift selbst, sondern auch zumindest der benachbarte Finger des Isolierstoffsockels in das Isolierstoffgehäuse der Leiteranschlussklemme eingeführt, während die Leiteranschlussklemme auf den Kontaktstift aufgesteckt wird. Mit Hilfe des dabei in die Durchgangsöffnung des Stromschienenstücks eintauchenden Fingers wird im ungesteckten Zustand ein gewisser Berührschutz für den Kontaktstift erreicht. Zudem wird die Führung des Kontaktstiftes zum Anklemmen an die Durchgangsöffnung verbessert und im Steckzustand ein stabiler Verbund von Leiteranschlussklemme und Isolierstoffsockel sichergestellt.The contact pin is advantageously received in a Isolierstoffsockel. The Isolierstoffsockel has a trained for immersion in the passage opening of the busbar piece fingers. Thus, not only the contact pin itself, but also at least the adjacent finger of the insulant base is inserted into the insulator housing of the conductor terminal, while the conductor terminal is plugged onto the contact pin. With the help of the thereby dipping into the through hole of the busbar piece finger a certain Berührschutz for the contact pin is achieved in the unmated condition. In addition, the leadership of the contact pin is improved for clamping to the through hole and secured in the plug state, a stable composite of conductor terminal and Isolierstoffsockel.

Vorteilhaft kann es dabei sein, wenn der Finger eine zur Bildung eines Überlastanschlages für den Klemmschenkel der Klemmfeder angepasste Länge hat, wenn das Isolierstoffgehäuse im Steckzustand auf den Isolierstoffsockel aufgesteckt und der Kontaktstift an das Stromschienenstück angeklemmt ist. Bei der Auslenkung des Klemmschenkels z.B. mit Hilfe eines Betätigungsdrückers, Betätigungshebels oder Betätigungswerkzeuges zum Anklemmen oder Entnehmen eines elektrischen Leiters stößt der Klemmschenkel somit an das freie Ende des Fingers an, um so eine übermäßige Auslenkung des Klemmschenkels und eine damit verbundene Überlastung der Klemmfeder zu verhindern.It may be advantageous in this case if the finger has a length adapted to form an overload stop for the clamping leg of the clamping spring, when the insulating housing is plugged onto the insulating base in the plug state and the Contact pin is clamped to the busbar piece. During the deflection of the clamping leg, for example with the aid of an actuating lever, operating lever or operating tool for clamping or removal of an electrical conductor, the clamping leg thus abuts against the free end of the finger so as to prevent excessive deflection of the clamping leg and an overloading of the clamping spring associated therewith.

Der Isolierstoffsockel hat vorzugsweise Rastelemente zur Verrastung an dem Isolierstoffgehäuse, wenn das Isolierstoffgehäuse im Steckzustand auf den Isolierstoffsockel aufgesteckt und der Kontaktstift an das Stromschienenstück angeklemmt ist, bzw. mit diesem kontaktiert ist. Damit wird im Steckzustand ein stabiler Verbund von Leiteranschlussklemme und Isolierstoffsockel geschaffen. Mit Hilfe der Verrastung wird verhindert, dass sich die Leiteranschlussklemme z.B. bei Zugbelastung auf einen angeklemmten elektrischen Leiter von dem Isolierstoffsockel und dem daran angeordneten Kontaktstiften löst.The Isolierstoffsockel preferably has latching elements for latching to the insulating housing when the insulating material plugged in the plug state on the Isolierstoffsockel and the contact pin is clamped to the busbar piece, or contacted with this. This creates a stable bond between the conductor terminal and insulating base in the plug-in state. By means of the latching it is prevented that the conductor connection terminal, e.g. when subjected to tensile stress on a clamped electrical conductor from the Isolierstoffsockel and arranged thereon contact pins.

Weiterhin ist es vorteilhaft, wenn die Stromschiene im Bereich des Durchbruchs an ihren einander gegenüberliegenden Außenkanten Ausnehmungen hat, in die jeweils ein Federarm des Anlageschenkels eintaucht. Mit Hilfe dieser Ausnehmungen (Buchten) gelingt es, die Federarme an den durch die Ausnehmung festgelegten Stellen an dem Stromschienenstück bzw. den einander gegenüberliegenden Seitenstegen des Stromschienenstücks festzulegen.Furthermore, it is advantageous if the busbar has recesses in the region of the opening at its opposite outer edges, in each of which a spring arm of the contact leg is inserted. With the help of these recesses (bays), it is possible to fix the spring arms at the locations defined by the recess on the conductor rail piece or the opposite side webs of the conductor rail piece.

Figur 1 lässt eine erste Ausführungsform einer Leiteranschlussklemme 1 erkennen. Die Leiteranschlussklemme 1 hat ein Isolierstoffgehäuse 2, das zweiteilig mit einem Oberteil 3 und einem Bodenteil 4 ausgebildet ist. Das Bodenteil 4 ist mit Rastelementen 5 in einer Rastöffnung 6 des Oberteils 3 verrastet. In das Isolierstoffgehäuse 2 ist ein Federkraftklemmanschluss eingebaut, der aus einer Klemmfeder 7 und einem Stromschienenstück 8 gebildet ist. Die Klemmfeder 7 ist als U-förmige Schenkelfeder mit einem Anlageschenkel 9, einem sich daran anschließenden Federbogen 10 und einem Klemmschenkel 11 ausgebildet. Der Klemmschenkel 11 hat an seinem freien Ende eine Klemmkante 12 zum Anklemmen eines elektrischen Leiters 16. FIG. 1 lets recognize a first embodiment of a conductor terminal 1. The conductor terminal 1 has an insulating housing 2, which is formed in two parts with an upper part 3 and a bottom part 4. The bottom part 4 is latched with locking elements 5 in a latching opening 6 of the upper part 3. In the insulating housing 2, a spring terminal connection is installed, which is formed from a clamping spring 7 and a busbar piece 8. The clamping spring 7 is a U-shaped leg spring with a plant leg 9, an adjoining spring bow 10 and a clamping leg 11 is formed. The clamping leg 11 has at its free end a clamping edge 12 for clamping an electrical conductor sixteenth

Das Stromschienenstück hat eine Durchgangsöffnung 13, die auf einer Seite durch einen Quersteg 14 begrenzt ist. Ein in eine Leitereinführungsöffnung 15 an der Oberseite des Isolierstoffgehäuses 2 eingeführter elektrischer Leiter 16 wird durch die Durchgangsöffnung 13 des Stromschienenstücks 8 geführt und mit Hilfe der Klemmkante 12 des Klemmschenkels 11 an eine Vorwölbung des Querstegs 14 angeklemmt. Damit wird der elektrische Leiter 16 mit Hilfe der Federkraft der Klemmfeder 7 elektrisch leitend und mechanisch fest an das Stromschienenstück 8 angeklemmt. Der elektrische Leiter 16 kann dabei ohne vorherige Auslenkung des Klemmschenkels 11 aus dem skizzierten Ruhezustand angeklemmt werden, da der Klemmschenkel 11 durch die Einsteckkraft des elektrischen Leiters 16 nach unten bzw. in Richtung Anlageschenkel 9 verlagert wird. Lediglich bei feindrähtigen elektrischen Leitern würde der elektrische Leiter 16 bei einem solchen Einstecken verbiegen. Dann ist eine Öffnung der durch Klemmkante 12 und Quersteg 14 gebildeten Klemmstelle für den elektrischen Leiter 16 mit Hilfe eines Betätigungselementes 17 erforderlich. Hierzu ist in dem dargestellten Beispiel als Betätigungselement 17 ein verschiebbar im Isolierstoffgehäuse 2 gelagerter Betätigungsdrücker vorgesehen. Dieser wird von außen z.B. mit einem Betätigungswerkzeug oder von Hand in das Isolierstoffgehäuse 2 hinein gedrückt, um hierbei den Klemmschenkel 11 der Klemmfeder in Richtung Anlageschenkel 9 zu verlagern und dabei die Klemmstelle zu öffnen.The busbar piece has a passage opening 13, which is bounded on one side by a transverse web 14. An inserted into a conductor insertion opening 15 at the top of the insulating housing 2 electrical conductor 16 is passed through the through hole 13 of the busbar piece 8 and clamped by means of the clamping edge 12 of the clamping leg 11 to a protrusion of the crosspiece 14. Thus, the electrical conductor 16 by means of the spring force of the clamping spring 7 is electrically conductively and mechanically clamped firmly to the busbar piece 8. The electrical conductor 16 can be clamped without prior deflection of the clamping leg 11 from the outlined idle state, since the clamping leg 11 is displaced by the insertion force of the electrical conductor 16 downwards or in the direction of plant leg 9. Only with finely stranded electrical conductors, the electrical conductor 16 would bend at such a plugging. Then an opening formed by clamping edge 12 and crossbar 14 clamping point for the electrical conductor 16 by means of an actuating element 17 is required. For this purpose, a displaceably mounted in the insulating housing 2 actuating lever is provided in the illustrated example as an actuating element 17. This is externally e.g. pressed with an actuating tool or by hand in the insulating 2, to thereby displace the clamping leg 11 of the clamping spring in the direction of plant leg 9 and thereby open the nip.

Die Durchgangsöffnung 13 erstreckt sich bis zum freien Ende des Stromschienenstücks 8 hin, der dem Quersteg 14 gegenüberliegt. Die Durchgangsöffnung 13 geht dabei in einem Durchbruch im Stromschienenstück über, der sich in Erstreckungsrichtung der Stromschiene erstreckt und an dem freien Ende, das dem Quersteg 14 gegenüberliegt, ausmündet. Damit hat das Stromschienenstück 8 zwei sich an den parallel zueinander in Erstreckungsrichtung des Stromschienenstücks 8 erstrecken und mit der Durchgangsöffnung 13 und dem Durchbruch beabstandete Seitenstege. Diese sind aufgrund des Durchbruchs aufeinander zu beweglich.The passage opening 13 extends to the free end of the busbar piece 8, which is opposite to the transverse web 14. The passage opening 13 passes in an opening in the busbar piece, which extends in the extension direction of the busbar and at the free end, which is opposite to the transverse web 14, opens. Thus, the busbar piece 8 has two extend to the parallel to each other in the extension direction of the busbar piece 8 and with the passage opening 13 and the breakthrough spaced side webs. These are movable towards each other due to the breakthrough.

Erkennbar ist, dass ein Kontaktstift 18 von der Unterseite in eine Kontaktstift-Einführungsöffnung 40 (Aufnahmeöffnung) im Bodenteil 4 in den Innenraum des Isolierstoffgehäuses 2 eingeführt ist. Dieser Kontaktstift 18 ist an einem Isolierstoffsockel 19 angeordnet. Dieser Isolierstoffsockel 19 bildet zusammen mit einem oder mehreren Kontaktstiften 18 eine Stiftleiste, die beispielsweise auf eine Leiterplatte aufgelötet sein kann. Denkbar ist aber auch, dass der Kontaktstift 18 mit dem Isolierstoffsockel 19 ein Teil eines Gegensteckverbinders für die Leiteranschlussklemme ist.It can be seen that a contact pin 18 from the bottom in a contact pin insertion opening 40 (receiving opening) in the bottom part 4 is inserted into the interior of the insulating housing 2. This contact pin 18 is arranged on a Isolierstoffsockel 19. This Isolierstoffsockel 19 together with one or more contact pins 18, a pin header, which may be soldered for example to a circuit board. It is also conceivable that the contact pin 18 with the Isolierstoffsockel 19 is part of a mating connector for the conductor terminal.

Erkennbar ist, dass der Kontaktstift 18 mit seinem freien Ende in die Durchgangsöffnung 13 des Stromschienenstücks 8 im Bereich des Durchbruchs am freien Ende eingesteckt ist. Der Anlageschenkel 9 der Klemmfeder 7 greift dabei mit zwei einander gegenüberliegenden Federarmen 20 an seinem freien Ende an das Stromschienenstück 8 an, um die mit Hilfe der Durchgangsöffnung 13 und des nicht erkennbaren Durchbruchs die relativ zueinander beweglichen Seitenstege des Stromschienenstücks 8 durch die Federkraft des Anlageschenkels 9 aufeinander zu zudrücken. Damit wird durch die Federarme 20 am freien Ende des Anlageschenkels 9 eine Klemmkraft auf das Stromschienenstück 8 aufgebracht, mit der ein eingeführter Kontaktstift 18 an das Stromschienenstück 8 angeklemmt wird.It can be seen that the contact pin 18 is inserted with its free end into the passage opening 13 of the busbar piece 8 in the region of the opening at the free end. The plant leg 9 of the clamping spring 7 engages with two opposing spring arms 20 at its free end to the busbar piece 8 to the with the help of the through hole 13 and the unrecognizable opening the relatively movable side webs of the busbar piece 8 by the spring force of the plant leg. 9 to press each other. This is applied by the spring arms 20 at the free end of the abutment leg 9, a clamping force on the busbar piece 8, with an inserted contact pin 18 is clamped to the busbar piece 8.

Deutlich wird weiterhin, dass von dem Isolierstoffsockel 19 ein Finger 21 abragt, der sich benachbart zum Kontaktstift 18 ebenfalls durch die Durchgangsöffnung 13 im Stromschienenstück 8 hindurch erstreckt. Der Finger 21 hat dabei eine Länge, die das freie Ende des Kontaktstifts 18 überragt. Damit wird ein einfacher Berührschutz erreicht, der eine Berührung des Kontaktstiftes 18 in ungestecktem Zustand verhindert oder zumindest erschwert. Zudem wird die Führung des Kontaktstifts 18 in die Durchgangsöffnung 13 oder den Durchbruch des Stromschienenstücks 8 beim Aufstecken der Leiteranschlussklemme 1 auf den Isolierstoffsockel 19 verbessert.It is also clear that protrudes from the Isolierstoffsockel 19, a finger 21 which extends adjacent to the contact pin 18 also through the passage opening 13 in the busbar piece 8 therethrough. The finger 21 has a length which projects beyond the free end of the contact pin 18. For a simple contact protection is achieved, which prevents contact of the contact pin 18 in the unplugged state or at least difficult. In addition, the leadership of the contact pin 18 is in the through hole 13 or the breakthrough of the conductor rail piece 8 when attaching the conductor terminal 1 on the Isolierstoffsockel 19 improved.

Die freie Stirnseite des Fingers 21 kann geneigt und an die angrenzenden Kontur des Bodenteils 4 angepasst sein. Der Finger 21 kann einen Überlastanschlag für die Klemmschenkel 14 bereitstellen, der eine übermäßige Verlagerung des Klemmschenkels 14 nach unten bzw. in Richtung Anlageschenkel 9 und damit eine Überlastung der Klemmfeder 7 verhindert, wenn das Isolierstoffgehäuse 2 im Steckzustand auf den Isolierstoffsockel 19 aufgesteckt ist..The free end face of the finger 21 may be inclined and adapted to the adjacent contour of the bottom part 4. The finger 21 can provide an overload stop for the clamping legs 14, which prevents excessive displacement of the clamping leg 14 down or in the direction of plant leg 9 and thus overloading of the clamping spring 7 when the insulating material 2 is plugged in the plug state on the insulating base 19 ..

Dies wird aus Figur 2 deutlicher, die eine Seiten-Schnittansicht der Leiteranschlussklemme 1 aus Figur 1 im nunmehr betätigten Zustand zeigt. Erkennbar ist, dass bei der maximalen möglichen Betätigung der Klemmschenkel 14 an dem Bodenteil 4 anliegt und auf der Stirnfläche am freien Ende des Fingers 21 aufliegt.This is going out FIG. 2 more clearly, the one side sectional view of the conductor terminal 1 from FIG. 1 in now actuated state shows. It can be seen that at the maximum possible actuation of the clamping leg 14 rests against the bottom part 4 and rests on the end face at the free end of the finger 21.

Aus Figuren 1 und 2 wird weiterhin deutlich, dass der Isolierstoffsockel 19 ein Rastelement 22 an einem Rastarm 23 hat. Dieses Rastelement 22 (z.B. Rastnase) rastet im endgültigen Steckzustand nach dem Aufstecken der Leiteranschlussklemme 1 auf den Isolierstoffsockel 19 aufgrund der Federelastizität des Rastarmes 23 in eine Rastöffnung 24 an der Außenseite des Isolierstoffgehäuses 2 ein, um einen Anschlag zu bilden. Damit wird ein abziehendes Isolierstoffgehäuse 2 von dem Isolierstoffsockel 19 verhindert.Out FIGS. 1 and 2 Furthermore, it is clear that the insulating material base 19 has a latching element 22 on a latching arm 23. This locking element 22 (eg locking lug) engages in the final plug state after attaching the conductor terminal 1 on the Isolierstoffsockel 19 due to the spring elasticity of the latching arm 23 in a detent opening 24 on the outside of the insulating housing 2, to form a stop. In order for a peeling Isolierstoffgehäuse 2 is prevented by the Isolierstoffsockel 19.

Figur 3 zeigt ein Beispiel für einen Federkraftklemmanschluss für eine solche Leiteranschlussklemme 1 in perspektivischer Rückseitenansicht. Erkennbar ist, dass das Stromschienenstück 8 U-förmig ausgebildet ist und eine sich in Längserstreckungsrichtung des Stromschienenstücks 8 erstreckende Durchgangsöffnung 13 hat. Hierdurch sind zwei voneinander beabstandete, auf einer gleichen Ebene liegende und sich in Längserstreckungsrichtung des Stromschienenstücks 8 erstreckende Seitenstege 25a, 25b gebildet. Die Durchgangsöffnung 13 ist an einem freien Ende des Stromschienenstücks 8 mit dem Querstege 14 begrenzt. Auf der dem Quersteg 14 gegenüberliegenden Seite des Stromschienenstücks 8 ist ein Durchbruch 26 vorhanden, mit dem die Durchgangsöffnung 13 zum freien Ende des Stromschienenstücks 8 hin ausmündet. Hierdurch sind die einander gegenüberliegenden Seitenstege 25a, 25b relativ zueinander beweglich und gerade nicht wie an der dem Durchbruch 26 gegenüberliegenden Seite durch den Quersteg 14 in ihrem Abstand lagefixiert. FIG. 3 shows an example of a spring force terminal connection for such a conductor terminal 1 in a perspective rear view. It can be seen that the busbar piece 8 is U-shaped and has a passage opening 13 extending in the longitudinal extension direction of the busbar piece 8. As a result, two side bars 25a, 25b which are spaced apart from one another and lie on the same plane and extend in the direction of longitudinal extension of the busbar piece 8 are formed. The passage opening 13 is bounded at a free end of the busbar piece 8 with the transverse webs 14. On the transverse web 14 opposite side of the busbar piece 8, an opening 26 is provided, with which the passage opening 13 opens to the free end of the busbar piece 8 out. As a result, the opposing side webs 25a, 25b are movable relative to each other and not fixed in position as at the opposite side of the opening 26 through the transverse web 14 in their distance.

Deutlich wird, dass der Anlageschenkel 9 an der Klemmfeder 7 mit einem sich in den Federbogen 10 hinein erstreckenden Schlitz 30 versehen ist, der den Anlageschenkel 9 in zwei nebeneinanderliegende und auf einer gleichen Ebene angeordnete Schenkelarme aufteilt. Diese Schenkelarme gehen in zwei voneinander beabstandete Federarme 20 über, die das Stromschienenstück 8 beidseits umgreifen. Die Federarme 20 sind mit einem Freiraum 27 oberhalb der Ebene des Stromschienenstücks 8 voneinander beabstandet, in den ein Kontaktstift 18 wie in den Figuren 1 und 2 dargestellt, eintauchen kann.It is clear that the plant leg 9 is provided on the clamping spring 7 with a extending into the spring bow 10 slot 30 which divides the plant leg 9 in two adjacent and arranged on a same level leg arms. These leg arms merge into two spaced-apart spring arms 20, which engage around the busbar piece 8 on both sides. The spring arms 20 are spaced apart with a clearance 27 above the plane of the busbar piece 8, in which a contact pin 18 as in the FIGS. 1 and 2 shown, can dip.

Deutlich wird, dass die Stromschiene 8 im Bereich des Durchbruchs 26 an ihren einander gegenüberliegenden Außenkanten Ausnehmungen 28 hat, in die jeweils ein zugeordneter Federarm 20 des Anlageschenkels 9 der Klemmfeder 7 eintaucht. Damit ist der Anlageschenkel 9 an dem Stromschienenstück 8 in Längserstreckungsrichtung des Stromschienenstücks 8 lagefixiert.It is clear that the busbar 8 in the region of the opening 26 at its opposite outer edges recesses 28, in each of which an associated spring arm 20 of the abutment leg 9 of the clamping spring 7 is immersed. Thus, the plant leg 9 is fixed in position on the busbar piece 8 in the longitudinal extension direction of the busbar piece 8.

Zusätzlich können die Federarme 20, wie in den Figuren 1 und 2 angedeutet, Abwinkelungen haben, die das Eintauchen des Anlageschenkels 9 in die Stromschiene nach unten begrenzen.In addition, the spring arms 20, as in the FIGS. 1 and 2 indicated, have bends that limit the immersion of the abutment leg 9 in the busbar down.

Mit Hilfe der voneinander beabstandeten Federarme 20, die das Stromschienenstück 8 umgreifen, wird eine Federkraft zumindest beim Aufspreitzen der Seitenstege 25a, 25b auf diese im Bereich des Durchbruchs 26 und des daran anschließenden Abschnitts der Durchgangsöffnung 13 ausgeübt, mit der ein eingesteckter Kontaktstift 18 unter Federkraft steckkontaktiert wird.With the help of the spaced spring arms 20 which surround the busbar piece 8, a spring force is at least when spreading the side bars 25a, 25b applied to this in the region of the opening 26 and the adjoining portion of the through hole 13, with an inserted contact pin 18 under spring force plug-contacted.

Deutlich wird, dass die Federkraft von der Klemmfeder 7 auf den Klemmschenkel 11 in Längserstreckungsrichtung der Klemmfeder 7 durch den Federbogen 10 aufgebracht wird. Die Klemmkraft auf das Stromschienenstück 8 im Bereich des Durchbruchs 26 wird hingegen durch die in Breitenrichtung der Klemmfeder 7 voneinander beabstandeten Federarme 20 und den optionalen Schlitz 30, welcher einen genügend großen Federweg der Federarme 20 ermöglicht, aufgebracht.It is clear that the spring force of the clamping spring 7 is applied to the clamping leg 11 in the longitudinal extension direction of the clamping spring 7 by the spring bow 10. The clamping force on the conductor rail piece 8 in the region of the opening 26, however, is applied by the spring arms 20, which are spaced apart in the width direction of the clamping spring 7, and the optional slot 30, which enables a sufficiently long spring travel of the spring arms 20.

Figur 4 lässt eine Schnittansicht in der Draufsicht auf das Stromschienenstück 8 aus Figur 3 mit eingestecktem Kontaktstift 18 und in die Durchgangsöffnung 13 eintauchenden Finger 21 des Isolierstoffsockels 19 erkennen. Deutlich wird, dass bei dem dargestellten Ausführungsbeispiel der Kontaktstift 18 im Bereich der durch die Federarme 20 aufgespannten Ebene in den Durchbruch 26 eingesteckt ist. Dabei werden die Seitenstege 25a, 25b durch den eingesteckten Kontaktstift 18 auseinandergespreitzt und es wird durch die Federarme 20 eine Gegenkraft auf den Kontaktstift 18 ausgeübt. Dadurch wird der Kontaktstift 18 an das Stromschienenstück 8 angeklemmt. FIG. 4 leaves a sectional view in the plan view of the busbar piece 8 from FIG. 3 detect with inserted contact pin 18 and in the passage opening 13 dipping fingers 21 of the insulating material 19. It is clear that in the illustrated embodiment, the contact pin 18 is inserted into the opening 26 in the plane defined by the spring arms 20 level. The side bars 25a, 25b are spread apart by the inserted contact pin 18 and it is exerted by the spring arms 20, a counter force on the contact pin 18. As a result, the contact pin 18 is clamped to the busbar piece 8.

Der Finger 21 hat eine an den Durchbruch 26 angepasste Kontur und ist mit einem teilkreisförmigen Zwischenraum von dem Kontaktstift 18 beabstandet.The finger 21 has a contour adapted to the aperture 26 and is spaced from the contact pin 18 with a part-circular gap.

Erkennbar ist auch, dass die Seitenstege 25a, 25b an den Außenkanten Ausnehmungen 28 z.B. in Form von rechteckförmigen Buchten haben, in die die Federarme 20 eintauchen.It can also be seen that the side webs 25a, 25b at the outer edges recesses 28, e.g. in the form of rectangular bays, in which the spring arms dip 20.

Figur 5 lässt eine Seiten-Schnittansicht einer zweiten Ausführungsform einer Leiteranschlussklemme 1 erkennen. Wiederum ist das Isolierstoffgehäuse 2 zweiteilig mit einem Oberteil 3 und einem Bodenteil 4 ausgeführt. Es ist auch eine U-förmig gebogene Schenkelfeder 7 vorgesehen, die zum Anklemmen eines elektrischen Leiters 16 an das Stromschienenstück 8 vorgesehen ist. Der elektrische Leiter 16 kann wiederum in eine Leitereinführungsöffnung 15 des Isolierstoffgehäuses 2 eingeführt und durch eine Durchgangsöffnung 13 im Stromschienenstück 8 hindurchgeführt werden. Im Hinblick auf die Klemmung des elektrischen Leiters 31 an die Klemmstelle 12 und dem Quersteg 14 wird auf die vorher beschriebene Ausführungsform verwiesen. In dem dargestellten Ausführungsbeispiel ist der Quersteg 14 nur nach oben entgegengesetzt zur Leitereinsteckrichtung L abgebogen, so dass die Klemmstelle 12 in einen Bereich oberhalb der Ebene der Durchgangsöffnung 13 verlagert wird. Deutlich wird, dass in dem dargestellten Zuführzustand der Klemmschenkel 11 nicht in den Durchbruch 26 eintaucht. FIG. 5 shows a side sectional view of a second embodiment of a conductor terminal 1 recognize. Again, the insulating housing 2 is made in two parts with an upper part 3 and a bottom part 4. It is also a U-shaped bent leg spring 7 is provided, which is provided for clamping an electrical conductor 16 to the busbar piece 8. The electrical conductor 16 can in turn be inserted into a conductor insertion opening 15 of the insulating housing 2 and passed through a passage opening 13 in the conductor rail piece 8. With regard to the clamping of the electrical conductor 31 to the nip 12 and the cross bar 14, reference is made to the previously described embodiment. In the illustrated embodiment, the cross bar 14 is bent only upwards opposite to the conductor insertion direction L, so that the clamping point 12 is displaced in an area above the plane of the through hole 13. It is clear that in the illustrated supply state of the clamping leg 11 is not immersed in the opening 26.

Anders als in dem vorher beschriebenen Ausführungsbeispiel wird der Kontaktstift 18 im Bereich des Durchbruchs 26 an der Durchgangsöffnung 13, d.h. benachbart zu den Federarmen 20 und ggf. dem Durchbruch 26 angeklemmt. Damit wird der etwas breitere Bereich der Durchgangsöffnung 13 für das Anklemmen des Kontaktstiftes 18 genutzt und nicht der sich hieran anschließende vorzugsweise schmalere Durchbruch 26. Der Kontaktstift 18 nutzt dabei den Bereich unterhalb des Federbogens 10 aus, um raumsparend in der Leiteranschlussklemme 1 platziert zu werden.Unlike in the previously described embodiment, the contact pin 18 in the region of the opening 26 at the through hole 13, ie adjacent to the spring arms 20 and possibly the opening 26 is clamped. Thus, the slightly wider area of the through hole 13 is used for the clamping of the contact pin 18 and not the adjoining preferably narrower opening 26. The contact pin 18 makes use of the area below the spring bow 10 in order to save space in the conductor terminal 1 to be placed.

Deutlich wird weiterhin, dass in diesem dargestellten Ausführungsbeispiel kein Isolierstoffsockel vorhanden ist, der in das Isolierstoffgehäuse 2 eintaucht. Der Kontaktstift 18 ist vielmehr ein einzelner Kontaktstift 18 oder als Kontaktleiste mit nicht dargestellten sehr niedrigen Isolierstoffsockel auf einer Leiterplatte 32 aufgelötet.It is also clear that in this illustrated embodiment, no Isolierstoffsockel is present, which dips into the insulating 2. The contact pin 18 is rather a single pin 18 or soldered as a contact strip with not shown very low insulating base on a circuit board 32.

Auch bei diesem Ausführungsbeispiel der Leiteranschlussklemme 1 umgreifen die voneinander beabstandeten Federarme 20 des Anlageschenkels 9 das Stromschienenstück 8 beidseits von der Außenseite, um die mit Hilfe des Durchbruchs 26 relativ zueinander beweglichen Seitenstege 25a, 25b mittels der Federkraft der Klemmfeder 7 mit dem Kontaktstift 18 zu kontaktieren.Also in this embodiment, the conductor terminal 1, the spaced spring arms 20 of the abutment leg 9 engage around the busbar piece 8 on both sides of the outside to contact the side bars 25a, 25b relative to each other with the help of the aperture 26 by means of the spring force of the clamping spring 7 with the contact pin 18 ,

Figur 6 lässt die Leiteranschlussklemme 1 aus Figur 5 in der Offenposition mit geöffneter Klemmstelle erkennen. Deutlich wird, dass auch hier durch Herunterdrücken des Betätigungselements 17 der Klemmschenkel 11 in Richtung Anlageschenkel 9 ausgelenkt wird. Damit wird die durch die Klemmkante am freien Ende des Klemmschenkels 11 und dem Quersteg 14 gebildete Klemmstelle zum Anklemmen eines elektrischen Leiters 31 geöffnet. FIG. 6 Leaves the wire connection terminal 1 off FIG. 5 Detect in open position with open nip. It is clear that also here by pressing down the actuating element 17 of the clamping leg 11 is deflected in the direction of plant leg 9. Thus, the clamping point formed by the clamping edge at the free end of the clamping leg 11 and the transverse web 14 for clamping an electrical conductor 31 is opened.

Figur 7 zeigt eine Draufsicht auf den Federkraftklemmanschluss der Leiteranschlussklemme 1 aus den Figuren 5 und 6 mit eingestecktem Kontaktstift 18. Deutlich wird, dass die Durchgangsöffnung 13 im Bereich des zur Aufnahme des elektrischen Leiters 16 vorgesehenen Raums angrenzend an den Quersteg 14 relativ breit ist und sich dann zunächst einmal in einen Schlitz übergehend verjüngt. Die Durchgangsöffnung 13 verbreitet sich dann durch zwei einander gegenüberliegende Buchten im Bereich des zum Anklemmen des Kontaktstifts 18 vorgesehenen Abschnitts, um sich dann wieder in dem zum freien Ende des Stromschienenstücks 8 auslaufenden Durchbruch 26 zu verjüngen. FIG. 7 shows a plan view of the Federkraftklemmanschluss the conductor terminal 1 of the Figures 5 and 6 with inserted contact pin 18. It is clear that the passage opening 13 in the region of the space provided for receiving the electrical conductor 16 adjacent to the transverse web 14 is relatively wide and then initially tapering into a slot. The passage opening 13 then spreads through two opposing bays in the region of the intended for clamping the contact pin 18 portion to then rejuvenate in the expiring to the free end of the busbar piece 8 opening 26.

Deutlich wird, dass auch hier mit Hilfe der Durchgangsöffnung 13 mit dem Durchbruch 26 am freien Ende zwei relativ zueinander bewegliche und durch diesen Freiraum/Schlitz voneinander getrennte Seitenstege 25a, 25b geschaffen werden.It is clear that with the help of the passage opening 13 with the opening 26 at the free end, two side bars 25a, 25b, which are movable relative to one another and are separated by this clearance / slot, are also created here.

Wiederum umgreifen die Federarme 20 des Anlageschenkels 9 der Klemmfeder 7 das Stromschienenstück 8 bzw. deren Seitenstege 25a, 25b von der Außenseite, um eine den Kontaktstift 18 festklemmende Federkraft auszuüben. Hierzu tauchen die Federarme 20 wieder in entsprechende Ausnehmungen 28 an der Außenkante der Seitenstege 25a, 25b im Bereich des freien Ende des Stromschienenstücks 8 gegenüberliegend zum Quersteg 14 ein.Again, the spring arms 20 of the support leg 9 of the clamping spring 7 engage around the busbar piece 8 or its side webs 25a, 25b from the outside in order to exert a spring force clamping the contact pin 18. For this purpose, the spring arms 20 dive again into corresponding recesses 28 on the outer edge of the side webs 25a, 25b in the region of the free end of the busbar piece 8 opposite to the transverse web 14.
