Description

Die Erfindung richtet sich auf eine Anschlussklemme mit einem Gehäuse, einer in dem Gehäuse angeordneten Stromschiene und einer in dem Gehäuse angeordneten Federklemme, wobei in dem Gehäuse eine Leitereinführöffnung ausgebildet ist, über welche ein zu klemmender Leiter einführbar ist. Ferner richtet sich die Erfindung auf ein Verfahren zur Herstellung einer Anschlussklemme.The invention is directed to a connection terminal having a housing, a busbar arranged in the housing and a spring terminal arranged in the housing, wherein in the housing a conductor insertion opening is formed, via which a conductor to be clamped can be inserted. Furthermore, the invention is directed to a method for producing a connection terminal.

Eine derartig ausgebildete Anschlussklemme dient dazu, einen Leiter mittels einer Federklemme an einer Stromschiene zu klemmen, um eine elektrische Verbindung herzustellen. Beim Einführen des zu klemmenden Leiters in das Gehäuse der Anschlussklemme kann es passieren, dass der Leiter verkippt und dabei neben die Klemmfeder oder die Stromschiene rutscht, und dadurch die elektrische Verbindung zwischen dem Leiter und der Stromschiene verhindert wird. Um dies zu vermeiden, ist es bekannt, an der Stromschiene oder der Federklemme ein Fenster auszubilden, durch welches der zu klemmende Leiter sicher geführt werden soll, und zusätzlich im Bereich des Fensters eine Ausbiegung an der Stromschiene bzw. der Klemmfeder vorzusehen, welche als Führung für den Leiter dient. Eine derartig ausgebildete Anschlussklemme ist beispielsweise aus der DE 10 2005 045 596 B3 bekannt. Nachteilig hierbei ist, dass aufgrund der speziellen Ausgestaltung der Stromschiene bzw. der Federklemme der Herstellungsaufwand für die Stromschiene bzw. der Federklemme und damit der gesamten Anschlussklemme sehr hoch ist, wodurch sich auch die Kosten für die Herstellung der Anschlussklemme erhöhen. Zudem benötigt eine derart ausgebildete Stromschiene bzw. Federklemme einen erhöhten Platzbedarf, wodurch die Abmessungen der Anschlussklemme ebenfalls erhöht sind.Such a trained terminal serves to clamp a conductor by means of a spring clip to a power rail to make an electrical connection. When inserting the conductor to be clamped in the housing of the terminal, it may happen that the conductor tilts while slipping next to the clamping spring or the bus bar, and thereby the electrical connection between the conductor and the bus bar is prevented. To avoid this, it is known to form a window on the busbar or the spring terminal, through which the conductor to be clamped is to be securely guided, and additionally provide in the region of the window a deflection on the busbar or the clamping spring, which serves as a guide for the leader. Such a trained terminal is for example from the DE 10 2005 045 596 B3 known. The disadvantage here is that due to the special design of the busbar or the spring terminal of the production cost of the busbar or spring clip and thus the entire terminal is very high, which also increase the cost of manufacturing the terminal. In addition, such a trained busbar or spring clamp requires an increased space requirement, whereby the dimensions of the terminal are also increased.

Aus der EP1575130A1 , der DE202006009460U1 und der DE202009002324U1 sind Anschlussklemmen bekannt. Der Erfindung liegt daher die Aufgabe zu Grunde, eine Lösung zu schaffen, mittels welcher eine sichere Klemmung eines Leiters in einer Anschlussklemme gewährleistet werden kann, ohne den Herstellungsaufwand und damit die Herstellungskosten der Anschlussklemme zu erhöhen.From the EP1575130A1 , the DE202006009460U1 and the DE202009002324U1 terminals are known. The invention is therefore based on the object to provide a solution by means of which a secure clamping of a conductor in a terminal can be ensured without increasing the manufacturing cost and thus the manufacturing cost of the terminal.

Bei einer Anschlussklemme der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß durch eine Anschlussklemme mit den Merkmalen des Anspruchs 1 gelöst.In a terminal of the type described in more detail, this object is achieved by a terminal with the features of claim 1.

Bei einem Verfahren zur Herstellung einer erfindungsgemäßen Anschlussklemme der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß durch das Verfahren mit den Merkmalen des Anspruchs 7 gelöst.In a method for producing a terminal according to the invention of the type described in more detail, this object is achieved by the method with the features of claim 7.

Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and advantageous developments of the invention are in the dependent claims specified.

Die Anschlussklemme gemäß der Erfindung zeichnet sich dadurch aus, dass diese eine Leiterführung aufweist, die eine sichere Führung eines zu klemmenden Leiters in einem vorzugsweise zu einer Seite geöffneten Gehäuse sicherstellt, wobei die Leiterführung nicht an der Stromschiene oder der Federklemme ausgebildet ist, sondern unmittelbar an dem Gehäuse angeformt ist. Die sich in Leitereinführrichtung erstreckende Leiterführung ist stegförmig ausgebildet und stellt eine einseitige Verlängerung der Leitereinführöffnung dar, indem sich die Leiterführung unmittelbar an die Leitereinführöffnung anschließt und einen Teil bzw. einen Bereich der seitlichen Öffnung des Gehäuses abdeckt bzw. verschließt. Beim Einführen eines zu klemmenden Leiters kann dadurch der Leiter unmittelbar nach dem Passieren der Leitereinführöffnung von der Leiterführung in den durch die Federklemme und die Stromschiene ausgebildeten Klemmbereich trotz des seitlich geöffneten Gehäuses sicher geführt werden, so dass eine Fehlmontage des Leiters in der Anschlussklemme verhindert werden kann. Bei der Herstellung einer derartigen Anschlussklemme kann die Fertigung der Leiterführung gleichzeitig mit der Ausbildung des gesamten Gehäuses während eines Spritzgießprozesses stattfinden, wodurch die Herstellung der Anschlussklemme schnell und einfach erfolgen kann, wobei nach dem Spritzgießen des Gehäuses mit der Leiterführung zur Ausbildung der Anschlussklemme nur noch die Stromschiene und die Federklemme in das Gehäuse eingesetzt werden müssen, wobei hierbei die Stromschiene und die Federklemme vorzugsweise über die seitliche Öffnung des Gehäuses seitlich in das Gehäuse eingeschoben werden können. Gegenüber einer Ausbildung einer Leiterführung an der Stromschiene oder einer Federklemme, wie dies aus dem Stand der Technik bekannt ist, können durch die erfindungsgemäße Lösung sowohl der Herstellungsaufwand als auch die Herstellungskosten reduziert werden. Als Stromschiene kann zudem vorzugsweise bei einer Anschlussklemme gemäß der Erfindung dadurch ein Schmalband verwendet werden und zudem kann der Transport der Stromschiene in einem Stanzwerkzeug bei der Herstellung der zu verwendenden Stromschiene reduziert werden. Durch die einstückige Ausbildung der Leiterführung mit dem Gehäuse ist die Leiterführung vorzugweise aus dem gleichen Material wie das Gehäuse ausgebildet.The terminal according to the invention is characterized in that it has a conductor guide, which ensures a secure guidance of a conductor to be clamped in a preferably open to one side housing, wherein the conductor guide is not formed on the busbar or the spring clip, but directly to molded to the housing. The conductor guide extending in the conductor insertion direction is bar-shaped and represents a one-sided extension of the conductor insertion opening, in that the conductor guide directly adjoins the conductor insertion opening and covers or closes a part or a region of the lateral opening of the housing. When inserting a conductor to be clamped, the conductor can thereby be guided safely after passing the Leitereinführöffnung of the conductor guide in the formed by the spring clip and the busbar clamping area despite the laterally open housing, so that incorrect assembly of the conductor can be prevented in the terminal , In the production of such a terminal, the production of the conductor can take place simultaneously with the formation of the entire housing during an injection molding process, whereby the production of the terminal can be done quickly and easily, after injection molding of the housing with the conductor guide to form the terminal only the Busbar and the spring clip must be inserted into the housing, in which case the busbar and the spring clip can be preferably inserted laterally into the housing via the lateral opening of the housing. Compared to a training of a conductor guide on the busbar or a spring clip, as is the case from the prior art is known, can be reduced by the inventive solution, both the manufacturing cost and the production cost. In addition, as a busbar preferably a narrow band can be used in a terminal according to the invention and also the transport of the busbar can be reduced in a punching tool in the production of the busbar to be used. Due to the one-piece design of the conductor guide with the housing, the conductor guide is preferably formed of the same material as the housing.

Nach einer bevorzugten Ausgestaltung der Anschlussklemme ist die Leiterführung derart ausgebildet, dass sie einen zwischen einem Klemmschenkel der Federklemme und der Stromschiene ausgebildeten Klemmbereich seitlich begrenzt und der Klemmschenkel der Federklemme mittels der Leiterführung verliersicher in dem Gehäuse gehalten ist. Vorzugsweise ist es vorgesehen, dass die Leiterführung eine Begrenzung des durch die Federklemme und die Stromschiene ausgebildeten Klemmbereiches, in welchem der Leiter mittels des Klemmschenkels der Federklemme an der Stromschiene geklemmt wird, ausbildet. Der Klemmeschenkel der Federklemme und die Seitenfläche der Stromschiene, an welcher der Leiter geklemmt wird, liegen sich vorzugsweise gegenüber, so dass die Leiterführung in Form des Steges seitlich versetzt zwischen dem Klemmschenkel der Federklemme und der Stromschiene angeordnet ist. Der zu klemmende Leiter wird von oben in den Klemmbereich zwischen dem Klemmschenkel und der Stromschiene eingeführt, wobei der Leiter entlang der Längserstreckung der Leiterführung geführt wird. Ein seitliches Verkippen oder Rutschen des zu klemmenden Leiters aus dem Klemmbereich kann somit durch die Leiterführung verhindert werden. Um eine besonders sichere Führung des Leiters gewährleisten zu können, ist es bevorzugt vorgesehen, dass die Leiterführung über den Klemmbereich hinausragt und nicht im Bereich des Klemmbereiches endet. Die Leiterführung ist ferner bevorzugt derart ausgebildet, dass die Leiterführung auch als Verliersicherung für die Federklemme in dem Gehäuse dient. Dies wird dadurch erreicht, dass die Federklemme mit ihrem Klemmschenkel hinter der Leiterführung bewegt wird und dadurch ein nach vorne Rutschen der Federklemme aus dem Gehäuse heraus verhindert werden kann. Beim Einsetzen der Federklemme in das Gehäuse wird dazu die Federklemme, welche vorzugsweise in Form einer Schenkelfeder ausgebildet ist, zusammengedrückt und anschließend zusammengedrückt in das Gehäuse seitlich eingeschoben. Durch das Zusammendrücken kann die Federklemme über die seitliche Öffnung des Gehäuses an der Leiterführung vorbei geführt werden. Sobald die Federklemme in dem Gehäuse an der gewünschten Stelle positioniert ist, wird die Federklemme entspannt, so dass der Klemmschenkel sich hinter der Leiterführung positionieren kann, so dass die Federklemme mittels der Leiterführung in dem Gehäuse gehalten wird und ein Verrutschen der Federklemme innerhalb des Gehäuses mittels der Leiterführung verhindert werden kann.According to a preferred embodiment of the terminal, the conductor guide is designed such that it laterally delimits a clamping region formed between a clamping leg of the spring terminal and the busbar and the clamping leg of the spring terminal is held captive in the housing by means of the conductor guide. Preferably, it is provided that the conductor guide forms a boundary of the clamping region formed by the spring clip and the busbar in which the conductor is clamped to the busbar by means of the clamping leg of the spring clip. The clamping leg of the spring clamp and the side surface of the busbar, on which the conductor is clamped, are preferably opposite, so that the conductor guide is arranged laterally offset in the form of the web between the clamping leg of the spring clip and the busbar. The conductor to be clamped is inserted from above into the clamping area between the clamping leg and the busbar, wherein the conductor is guided along the longitudinal extension of the conductor guide. A lateral tilting or slipping of the conductor to be clamped from the clamping area can thus be prevented by the conductor guide. To be a special To ensure safe guidance of the conductor, it is preferably provided that the conductor guide protrudes beyond the clamping area and does not end in the region of the clamping area. The conductor guide is further preferably designed such that the conductor guide also serves as a captive for the spring clip in the housing. This is achieved by moving the spring clip with its clamping leg behind the ladder guide and thereby preventing forward slipping of the spring clip out of the housing. When inserting the spring clip into the housing to the spring clip, which is preferably designed in the form of a leg spring, compressed and then pressed together pushed laterally into the housing. By compressing the spring clip can be passed over the side opening of the housing on the conductor guide over. Once the spring clip is positioned in the housing at the desired location, the spring clip is relaxed so that the clip leg can locate behind the wire guide so that the spring clip is held within the housing by the wire guide and the spring clip will slip within the housing the conductor guide can be prevented.

Um auch eine sichere Positionierung der Stromschiene in dem Gehäuse gewährleisten zu können, ist es bevorzugt vorgesehen, dass die Stromschiene über einen Verrastungsmechanismus an der Leiterführung befestigt ist. Über den Verrastungsmechanismus kann die Stromschiene beispielsweise an der Leiterführung eingehakt bzw. eingerastet werden. Die Stromschiene kann dadurch in einer festen Position zu der Leiterführung gehalten werden.In order to ensure a secure positioning of the busbar in the housing, it is preferably provided that the busbar is fastened via a latching mechanism on the conductor guide. About the Verrastungsmechanismus the busbar can be hooked or engaged, for example, on the conductor guide. The busbar can thereby be held in a fixed position to the conductor guide.

Weiter ist es vorzugsweise vorgesehen, dass die Stromschiene im Wesentlichen L-förmig ausgebildet ist. Durch die L-förmige Ausbildung der Stromschiene kann die Stromschiene besonders Platz sparend in dem Gehäuse angeordnet werden, wobei die Stromschiene vorzugsweise entlang einer Innenwand des Gehäuses angeordnet ist. Aufgrund der Platz sparenden Anordnung der Stromschiene kann die gesamte Anschlussklemme kompakter, mit geringeren Abmessungen ausgebildet werden, wodurch der notwendige Bauraum für eine Anschlussklemme reduziert werden kann.Further, it is preferably provided that the busbar is formed substantially L-shaped. Due to the L-shaped design of the busbar, the busbar can be arranged in a particularly space-saving manner in the housing, wherein the busbar is preferably arranged along an inner wall of the housing. Due to the space-saving arrangement of the busbar, the entire terminal can be made more compact, with smaller dimensions, whereby the necessary space for a terminal can be reduced.

Eine weiter bevorzugte Ausgestaltung der Anschlussklemme gemäß der Erfindung sieht vor, dass an der Leiterführung ein Federwegbegrenzungselement angeformt ist. Das Federwegbegrenzungselement dient als Anschlag für den Klemmschenkel der Federklemme bei einem Ausbiegen des Klemmschenkels während des Einführens des Leiters in den Klemmbereich und/oder dem Lösen des Leiters aus dem Klemmbereich. Hierdurch kann die maximale Auslenkung des Klemmschenkels der Federklemme durch Betätigen mit einem Leiter oder einem Lösewerkzeug reduziert werden, wodurch verhindert wird, dass der Klemmschenkel bis zur Montageöffnung gedrückt werden kann. Aufgrund der reduzierten, möglichen Auslenkung des Klemmschenkels kann das Einführen und Lösen eines Leiters schneller erfolgen, so dass die benötigte Zeit für eine Klemmung eines Leiters und/oder einem Lösen des Leiters reduziert werden kann. Das Federwegbegrenzungselement steht vorzugsweise mit seiner Längsachse winklig, bevorzugt mit einem Winkel zwischen 20° und 60°, von der Längsachse der stegförmigen Leiterführung ab. Vorzugsweise ist das Federwegbegrenzungselement in Form eines Fingers ausgebildet und an einem freien Ende der stegförmigen Leiterführung, welches der Leitereinführöffnung gegenüberliegt, angeformt.A further preferred embodiment of the terminal according to the invention provides that on the conductor guide a Federwegbegrenzungselement is formed. The Federwegbegrenzungselement serves as a stop for the clamping leg of the spring clip in a deflection of the clamping leg during the insertion of the conductor in the clamping area and / or the release of the conductor from the clamping area. In this way, the maximum deflection of the clamping leg of the spring clip can be reduced by pressing with a conductor or a release tool, thereby preventing the clamping leg can be pressed to the mounting hole. Due to the reduced, possible deflection of the clamping leg, the insertion and removal of a conductor can be done faster, so that the time required for a clamping of a conductor and / or a release of the conductor can be reduced. The spring travel limiting element is preferably angled with its longitudinal axis, preferably at an angle between 20 ° and 60 °, from the longitudinal axis of the web-shaped conductor guide. Preferably, the Federwegbegrenzungselement is formed in the shape of a finger and at a free end of the web-shaped conductor guide, which is opposite to the Leitereinführöffnung formed.

Um die Stabilität der stegförmig ausgebildeten Leiterführung zu erhöhen, ist es ferner vorzugsweise vorgesehen, dass die Leiterführung mindestens zwei Verbindungsstellen mit dem Gehäuse aufweist. Eine erste Verbindungsstelle ist vorzugsweise an der Anformung der stegförmigen Leiterführung an dem Gehäuse angrenzend zu der Leitereinführöffnung vorgesehen. Eine zweite Verbindungsstelle kann beispielsweise an dem freien Ende der stegförmigen Leiterführung gegenüberliegend zu der Leitereinführöffnung vorgesehen sein. Es ist aber auch beispielsweise möglich, die zweite oder eine weitere Verbindungsstelle der Leiterführung mit dem Gehäuse über das Federwegbegrenzungselement vorzusehen, indem das Federwegbegrenzungselement mit dem Gehäuse verbunden ist und somit vorzugsweise einstückig mit dem Gehäuse ausgebildet ist. Durch die zwei oder mehr Verbindungsstellen kann auch die Herstellung der Leiterführung und damit die Herstellung der Anschlussklemme verbessert werden, da durch die mehreren Verbindungsstellen ein Einfallen des Spritzgussmaterials im Bereich der Leiterführung verhindert werden kann. Vorzugsweise ist die Leiterführung an jeder vorgesehenen Verbindungsstelle unmittelbar oder über ein weiteres Element einstückig mit dem Gehäuse verbunden.In order to increase the stability of the web-shaped conductor guide, it is further preferably provided that the conductor guide has at least two connection points with the housing. A first connection point is preferably provided on the molding of the web-shaped conductor guide on the housing adjacent to the conductor insertion opening. A second connection point may be provided, for example, at the free end of the web-shaped conductor guide opposite to the conductor insertion opening. But it is also possible, for example, to provide the second or a further connection point of the conductor guide with the housing via the spring travel limiting element by the spring travel limiting element is connected to the housing and thus preferably formed integrally with the housing. The two or more connection points can also be used to improve the production of the conductor guide and thus the production of the terminal, since the plurality of connection points can prevent the injection molding material from collapsing in the region of the conductor guide. Preferably, the conductor guide is connected at each intended connection point directly or via a further element integrally with the housing.

Erfindungsgemäß ist die Stromschiene in einem zwischen der Leiterführung und einer Innenwand des Gehäuses ausgebildeten Freiraum bzw. Spalt eingeschoben. Hierdurch kann eine einfache Montage der Stromschiene in dem Gehäuse gewährleistet werden, indem die Stromschiene leicht über die seitliche Öffnung des Gehäuses in einen Bereich zwischen der Innenwand des Gehäuses und der Leiterführung eingeführt werden kann. Die Montage der Stromschiene in dem Gehäuse wird somit nicht durch die einstückig mit dem Gehäuse ausgebildete Leiterführung behindert.According to the invention, the bus bar is inserted in a free space or gap formed between the conductor guide and an inner wall of the housing. As a result, a simple mounting of the busbar can be ensured in the housing by the busbar can be easily inserted through the side opening of the housing in a region between the inner wall of the housing and the conductor guide. The assembly of Busbar in the housing is thus not hindered by the integrally formed with the housing conductor.

Nachfolgend wird die Erfindung unter Bezugnahme auf die anliegenden Zeichnungen anhand einer bevorzugten Ausführungsform näher erläutert.The invention will be explained in more detail below with reference to the accompanying drawings with reference to a preferred embodiment.

Fig. 1, 2 und 4 zeigen eine schematische Darstellung einer Anschlussklemme gemäß der Erfindung. Die Anschlussklemme weist ein Gehäuse 1 mit einem Innenraum 2 auf, wobei in dem Innenraum 2 des Gehäuses 1 eine Stromschiene 3 und eine Federklemme 4 angeordnet sind. Fig. 1 . 2 and 4 show a schematic representation of a terminal according to the invention. The terminal has a housing 1 with an inner space 2, wherein in the interior 2 of the housing 1, a busbar 3 and a spring terminal 4 are arranged.

Die Stromschiene 3 ist aus einem schmalen Metallband ausgebildet und in Form eines L's gebogen. In dem in das Gehäuse 1 eingesetzten Zustand, wie in Fig. 1 gezeigt, liegt die Stromschiene 3 an einer Innenwand 5 des Gehäuses 1 an. Das Gehäuse 1 weist, wie in Fig. 1 zu erkennen ist, an einer Längsseitenfläche eine Öffnung 21 auf, so dass das Gehäuse 1 seitlich geöffnet ausgebildet ist. Das Gehäuse 1 ist somit ein auf einer Seite offenes Gehäuse 1. Über diese seitliche Öffnung 21 wird die Stromschiene 3 in das Gehäuse 1 eingesetzt.The busbar 3 is formed from a narrow metal band and bent in the form of an L's. In that in the Housing 1 inserted state, as in Fig. 1 shown, the busbar 3 is located on an inner wall 5 of the housing 1 at. The housing 1 has, as in Fig. 1 can be seen on an elongated side surface, an opening 21, so that the housing 1 is formed laterally open. The housing 1 is thus a housing 1 which is open on one side. Via this lateral opening 21, the busbar 3 is inserted into the housing 1.

Die Federklemme 4 ist in Form einer Schenkelfeder mit einem Halteschenkel 20 und einem Klemmschenkel 6 ausgebildet. Die Federklemme 4 ist auf einem in dem Gehäuse 1 ausgebildeten Halteelement 7 aufgeschoben, welches vorzugsweise einstückig mit dem Gehäuse 1 ausgebildet ist. Für das Aufschieben der Federklemme 4 auf das Halteelement 7 wird auch die Federklemme 4 über die seitliche Öffnung 21 in das Gehäuse 1 eingebracht.The spring clip 4 is formed in the form of a leg spring with a holding leg 20 and a clamping leg 6. The spring clip 4 is pushed onto a holding element 7 formed in the housing 1, which is preferably formed integrally with the housing 1. For pushing on the spring clip 4 on the retaining element 7 and the spring clip 4 is introduced via the lateral opening 21 in the housing 1.

In dem Gehäuse 1 selber ist eine Leitereinführöffnung 8 ausgebildet, über welche ein zu klemmender Leiter 9, wie er in Fig. 4 gezeigt ist, eingeführt werden kann, um mittels des Klemmschenkels 6 der Federklemme 4 gegen die Stromschiene 3 geklemmt zu werden.In the housing 1 itself a Leitereinführöffnung 8 is formed, via which a conductor to be clamped 9, as in Fig. 4 is shown, can be introduced to be clamped by means of the clamping leg 6 of the spring clip 4 against the busbar 3.

Die Anschlussklemme weist ferner eine Leiterführung 10 für den zu klemmenden Leiter 9 auf, welche stegförmig ausgebildet ist und unterhalb der Leitereinführöffnung 8 ausgebildet ist, so dass die Leiterführung 10 in Form einer stegförmigen Verlängerung der Leitereinführöffnung 8 ausgebildet ist. Die Leiterführung 10 erstreckt sich ausgehend von der Leitereinführöffnung 8 in Einführrichtung 11 des zu klemmenden Leiters 9 in den Innenraum 2 des Gehäuses 1 hinein. Die Leiterführung 10 ist einseitig, in Form eines von der Leitereinführöffnung 8 abstehenden, dünnen Steges ausgebildet, wobei die Leiterführung 10 einstückig mit dem Gehäuse 1 ausgebildet ist, so dass die Leiterführung 10 während eines Spritzgießprozesses zusammen mit dem Gehäuse 1 ausgeformt werden kann. Die Leiterführung 10 ist im Bereich der seitlichen Öffnung 21 des Gehäuses 1 ausgebildet, so dass die Leiterführung 10 die seitliche Öffnung 21 des Gehäuses 1 teilweise bzw. bereichsweise abdeckt bzw. verschließt.The terminal further comprises a conductor guide 10 for the conductor to be clamped 9, which is web-shaped and is formed below the conductor insertion 8, so that the conductor guide 10 is formed in the form of a web-shaped extension of the conductor insertion 8. The conductor guide 10 extends from the conductor insertion opening 8 in the insertion direction 11 of the conductor 9 to be clamped into the interior 2 of the housing 1. The conductor guide 10 is one-sided, in the form of a protruding from the conductor insertion 8, formed thin web, wherein the conductor guide 10 is integrally formed with the housing 1, so that the conductor guide 10 can be formed during an injection molding together with the housing 1. The conductor guide 10 is formed in the region of the lateral opening 21 of the housing 1, so that the conductor guide 10 covers or closes the lateral opening 21 of the housing 1 partially or in regions.

Die Leiterführung 10 ist derart ausgebildet, dass sie einen zwischen dem Klemmschenkel 6 und der Stromschiene 3 ausgebildeten Klemmbereich seitlich in Richtung der seitlichen Öffnung 21 des Gehäuses 1 begrenzt. Der Klemmschenkel 6 der Federklemme 4 und die Seitenfläche 13 der Stromschiene 3, an welcher der Leiter 9 geklemmt wird, liegen sich gegenüber, so dass die Leiterführung 10 in Form des Steges seitlich versetzt zwischen dem Klemmschenkel 6 der Federklemme 4 und der Stromschiene 3 angeordnet ist. Der zu klemmende Leiter 9 wird von oben in den Klemmbereich zwischen dem Klemmschenkel 6 und der Stromschiene 3 eingeführt, wobei der Leiter 9 entlang der Längserstreckung der Leiterführung 10 geführt wird. Ein seitliches Verkippen oder Rutschen des zu klemmenden Leiters 9 aus dem Klemmbereich kann somit durch die Leiterführung 10 verhindert werden. Die Leiterführung 10 ist in ihrer Längserstreckung derart lang ausgebildet, dass sie über den Klemmbereich hinausragt und nicht im Bereich des Klemmbereiches endet.The conductor guide 10 is designed such that it limits a clamping region formed between the clamping leg 6 and the busbar 3 laterally in the direction of the lateral opening 21 of the housing 1. The clamping leg 6 of the spring terminal 4 and the side surface 13 of the busbar 3, to which the conductor 9 is clamped, are opposite, so that the conductor guide 10 is laterally offset in the form of the web between the clamping leg 6 of the spring terminal 4 and the busbar 3 , The conductor to be clamped 9 is inserted from above into the clamping area between the clamping leg 6 and the busbar 3, wherein the conductor 9 is guided along the longitudinal extent of the conductor guide 10. A lateral tilting or slipping of the clamped conductor 9 from the clamping area can thus be prevented by the conductor guide 10. The conductor guide 10 is formed in its longitudinal extent so long that it projects beyond the clamping area and does not end in the region of the clamping area.

Die Leiterführung 10 dient auch als Verliersicherung der Federklemme 5, da ein nach vorne Rutschen der Federklemme 4 von dem Halteelement 3 durch die Leiterführung 10 verhindert wird, da der Klemmschenkel 6 der Federklemme 4 hinter der Leiterführung 10 angeordnet und dort mittels des Leiters 9 bzw. einem Lösewerkzeug, beispielsweise einem Drücker 12, wie er in Fig. 4 gezeigt ist, betätigt werden kann.The conductor guide 10 also serves as a captive securing the spring clip 5, since a forward sliding of the spring clip 4 is prevented by the support member 3 through the conductor guide 10, since the clamping leg 6 of the spring terminal 4 is arranged behind the conductor guide 10 and there by means of Conductor 9 and a release tool, such as a pusher 12, as in Fig. 4 is shown, can be operated.

Die Leiterführung 10 ist beabstandet zu der Innenwand 5 des Gehäuses 1 ausgebildet, so dass ein Freiraum bzw. Spalt 22 in Klemmrichtung des Klemmschenkels 6 der Federklemme 4 zwischen der in Richtung Innenwand 5 des Gehäuses 1 zeigenden Längsseite 14 der Leiterführung 10 und der Innenwand 5 des Gehäuses 1 sowie ein Freiraum bzw. Spalt 23 in Leitereinführrichtung 11 zwischen der Querseite 15 des freien Endes 16 der Leiterführung 10 und der als Bodenfläche ausgebildeten Innenwand 5 des Gehäuses 1 ausgebildet ist. Über den Spalt 22 und den Spalt 23 zwischen der Leiterführung 10 und der Innenwand 5 des Gehäuses 1 kann die Stromschiene 3 in das Gehäuse 1 eingesetzt werden.The conductor guide 10 is spaced from the inner wall 5 of the housing 1, so that a clearance or gap 22 in the clamping direction of the clamping leg 6 of the spring clip 4 between pointing in the direction of the inner wall 5 of the housing 1 longitudinal side 14 of the conductor guide 10 and the inner wall 5 of Housing 1 and a clearance or gap 23 in the conductor insertion direction 11 between the transverse side 15 of the free end 16 of the conductor guide 10 and formed as a bottom surface inner wall 5 of the housing 1 is formed. Via the gap 22 and the gap 23 between the conductor guide 10 and the inner wall 5 of the housing 1, the busbar 3 can be inserted into the housing 1.

Um das Einschieben der Stromschiene 3 in den Spalt 22 und den Spalt 23 zu erleichtern, weist die Innenwand 5 des Gehäuses 1 an ihren zu der seitlichen Öffnung 21 angrenzenden Kanten 24, 25 jeweils eine Einführfase auf.In order to facilitate the insertion of the busbar 3 in the gap 22 and the gap 23, the inner wall 5 of the housing 1 at their adjacent to the lateral opening 21 edges 24, 25 each have a Einführfase.

Im eingesetzten Zustand ist die Stromschiene 3 über einen Verrastungsmechanismus 17, wie er in Fig. 2 gezeigt ist, an der Längsseite 14 der Leiterführung 10 befestigt, so dass die Leiterführung 10 auch zum sicheren Fixieren der Stromschiene 3 in dem Gehäuse 1 dienen kann.In the inserted state, the busbar 3 via a Verrastungsmechanismus 17, as in Fig. 2 is shown attached to the longitudinal side 14 of the conductor guide 10, so that the conductor guide 10 can also serve for secure fixing of the busbar 3 in the housing 1.

An dem freien Ende 16 der Leiterführung 10 ist ein Federwegbegrenzungselement 18 ausgebildet, welches vorzugsweise einstückig an der Leiterführung 10 angeformt ist, so dass auch das Federwegbegrenzungselement 18 beim Spritzgießen des Gehäuses 1 unmittelbar mit ausgeformt werden kann. Das Federwegbegrenzungselement 18, welches die maximale Auslenkung des Klemmschenkels 6 der Federklemme 4 begrenzt, ist in Form eines Fingers ausgebildet, welcher in einem Winkel von im Wesentlichen 90° verdreht zu der stegförmigen Leiterführung 10 in den Innenraum 2 des Gehäuses 1 ragt. Das Federwegbegrenzungselement 18 steht zudem winklig, bevorzugt mit einem Winkel zwischen 20° und 60°, von der Längsachse der stegförmigen Leiterführung 10 ab.At the free end 16 of the conductor guide 10 is a Federwegbegrenzungselement 18 is formed, which is preferably integrally formed on the conductor guide 10, so that the Federwegbegrenzungselement 18 during injection molding of the housing 1 formed directly with can be. The Federwegbegrenzungselement 18, which limits the maximum deflection of the clamping leg 6 of the spring clip 4 is formed in the shape of a finger, which is rotated at an angle of substantially 90 ° to the web-shaped conductor guide 10 into the interior 2 of the housing 1. The spring travel limiting element 18 also protrudes at an angle, preferably at an angle between 20 ° and 60 °, from the longitudinal axis of the web-shaped conductor guide 10.

Wie in Fig. 2 zu erkennen ist, ist das Federwegbegrenzungselement 18 über einen Steg 19 mit dem Halteelement 7 verbunden, so dass zusätzlich zu der Verbindungsstelle der Leiterführung 10 mit dem Gehäuse 1 im Bereich der Leitereinführöffnung 8 die Leiterführung 10 über das Federwegbegrenzungselement 18, den Steg 19 und das Halteelement 7 mit dem Gehäuse 1 verbunden ist, und hierdurch eine zweite Verbindungsstelle der Leiterführung 10 mit dem Gehäuse 1 ausgebildet wird. An den beiden Verbindungsstellen ist vorzugsweise eine einstückige Ausbildung mit dem Gehäuse 1 vorgesehen.As in Fig. 2 can be seen, the Federwegbegrenzungselement 18 is connected via a web 19 with the holding element 7, so that in addition to the junction of the conductor guide 10 with the housing 1 in the region of the conductor insertion opening 8, the conductor guide 10 via the Federwegbegrenzungselement 18, the web 19 and the support member 7 is connected to the housing 1, and thereby a second connection point of the conductor guide 10 is formed with the housing 1. At the two connection points, a one-piece design with the housing 1 is preferably provided.

In Fig. 3 ist ferner ein Schritt zum Herstellen einer Anschlussklemme gezeigt, bei dem die Federklemme 4 in das Gehäuse 1 über die Öffnung 21 seitlich eingeführt wird. Beim Einsetzen der Federklemme 4 in das Gehäuse 1 wird die Federklemme 4 zusammengedrückt und zusammengedrückt über die seitliche Öffnung 21 in das Gehäuse 1 eingeschoben. Durch das Zusammendrücken kann die Federklemme 4 an der Leiterführung 10 vorbei durch einen zwischen der Leiterführung 10 und dem Federwegbegrenzungselement ausgebildeten Freiraum 26, welcher Teil der seitlichen Öffnung 21 ist, geführt werden, wie dies in Fig. 3 gezeigt ist. Sobald die Federklemme 4 in dem Gehäuse 1 an der gewünschten Stelle positioniert ist, wird die Federklemme 4 wieder entspannt, so dass der Klemmschenkel 6 der Federklemme 4 sich hinter der Leiterführung 10 positionieren kann, wie dies insbesondere in Fig. 1 zu erkennen ist, so dass die Federklemme 4 mittels der Leiterführung 10 in dem Gehäuse 1 gehalten wird und ein Verrutschen der Federklemme 4 innerhalb des Gehäuses 1 mittels der Leiterführung 10 verhindert werden kann.

When inserting the spring clip 4 in the housing 1, the spring clip 4 is compressed and pushed together via the lateral opening 21 into the housing 1. By compressing, the spring clip 4 can be guided past the conductor guide 10 by a free space 26 formed between the conductor guide 10 and the spring travel limiting element, which is part of the lateral opening 21, as shown in FIG Fig. 3 is shown. Once the spring clip 4 in the housing 1 at the is positioned desired location, the spring clip 4 is relaxed again, so that the clamping leg 6 of the spring clip 4 can position itself behind the conductor guide 10, as in particular Fig. 1 can be seen, so that the spring clip 4 is held by means of the conductor guide 10 in the housing 1 and slipping of the spring clip 4 can be prevented within the housing 1 by means of the conductor guide 10.
