Description
Die Erfindung betrifft eine elektrische Anschlussklemme nach dem Oberbegriff
des Patentanspruches 1.The invention relates to an electrical connection terminal according to the preamble
of
Eine solche Anschlussklemme ist aus der DE 2005923 A bekannt. Diese bekannte Anschlussklemme weist in verschiedenen Ausführungsformen ein Gehäuse mit einer Einführungsbahn einer Stromschiene für das freie Ende eines elektrischen Leiters auf, der durch eine im Gehäuse gehaltene Klemmfeder gegen die Einführungsbahn gedrückt wird. An der Stromschiene ist eine weitere Anschlussstelle für einen weiteren Leiter vorgesehen, wobei das Gehäuse aus elektrisch leitendem Material besteht und die Stromschiene bildet und im Anschluss an die Einführungsbahn mit einer Kontaktfläche für einen weiteren Leiter versehen ist, gegen die ein zweiter Schenkel der Klemmfeder drückt.Such a connection terminal is known from DE 2005923 A. This known terminal has in different embodiments a housing with an insertion track of a busbar for the free End of an electrical conductor on which is held in the housing Clamp spring is pressed against the insertion path. At the Busbar is another connection point for another conductor provided, wherein the housing consists of electrically conductive material and forms the busbar and following the entry track is provided with a contact surface for another conductor, against which presses a second leg of the clamping spring.
Anschlussklemmen dieser Art sind zur Kontaktierung von zwei gleich ausgebildeten elektrischen Leitern geeignet, eignen sich aber nicht zum Anschluss einfacher Bandleiter, wie sie beispielsweise bei Einbaudosen von Elektroinstallationssystemen nach der von der Anmelderin stammenden deutschen Patentanmeldung 19816554.4 zum Einsatz kommen.Terminal blocks of this type are the same for contacting two trained electrical conductors suitable, but are not suitable for Connection of simple strip conductors, such as those used for installation boxes of electrical installation systems according to that of the applicant German patent application 19816554.4 are used.
Andere Bauarten von Anschlussklemmen sind aus der DE 4014048 A1 bekannt, wo man das Gehäuse aus einem isolierenden Werkstoff hergestellt hat und die Klemmfeder mit einer Stromschiene zusammenwirken lässt, die in die Einführungsbahn hereinragt und mit ihrem anderen Ende als Flachsteckhülse oder als Steckerzunge ausgebildet ist. Anschlussklemmen dieser Art weisen auch den Vorteil auf, dass schraublose Klemmstellen gebildet sind, die ohne Hilfsmittel angeschlossen werden können. Nachteilig ist aber, dass die Abmessungen zum Teil sehr groß werden und das gewünschte Spektrum für anzuschließende Kabeldurchmesser nicht abgedeckt wird.Other types of connection terminals are from DE 4014048 A1 known where to make the housing from an insulating material has and the clamping spring interact with a busbar leaves, which protrudes into the introduction path and with their other End is designed as a flat receptacle or as a tongue. terminals This type also has the advantage of being screwless Terminal points are formed, which are connected without tools can. The disadvantage, however, is that the dimensions are sometimes very large become large and the desired spectrum for the cable diameter to be connected is not covered.
Aus der DE 2440825 A1 ist ferner ein Kontaktstück für eine Anschlussklemme bekannt, das zur Aufnahme in einem aus Isoliermaterial hergestellten Gehäuse dient und bei einer Ausführungsform aus einem U-förmig gebogenen Halteteil besteht an dessen Innenschenkel zwei S-förmig gebogene Federn eingefügt sind. Andere Ausführungsformen, die ebenfalls dort gezeigt sind, sehen ein massives Kontaktteil vor, das mit parallel zueinander verlaufenden rinnenförmigen Vertiefungen versehen ist, bei denen die Kontaktgabe jeweils innerhalb der Rinnen erfolgt, so dass kein Teil der Klemmfeder eine Außenseite des Kontaktstückes überragt. Auch solche Bauarten sind nicht zum Anschluss einfacher Bandleiter geeignet und sie sind vor allen Dingen in der Herstellung relativ aufwendig. Solche Kontaktstücke müssen auch stets von Isoliergehäusen ummantelt werden.From DE 2440825 A1 there is also a contact piece for a connecting terminal known to be included in a made of insulating material Serves housing and in one embodiment from a U-shaped curved holding part consists of two S-shaped on the inner leg curved springs are inserted. Other embodiments that are also shown there, provide a solid contact part that with trough-shaped depressions running parallel to each other where contact is made within the channels, so that no part of the clamping spring projects beyond an outside of the contact piece. Such types are also not easier to connect Band conductors are suitable and, above all, they are relative in production consuming. Such contact pieces must always be made of insulating housings to be encased.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde eine Anschlussklemme der eingangs genannten Art so auszubilden, dass ein universeller Einsatz möglich ist und dass auch ein einfacher Anschluss an einen Bandleiter vorgesehen werden kann. The present invention is therefore based on the object of a connecting terminal of the type mentioned in such a way that a universal use is possible and that also a simple connection can be provided on a strip conductor.
Zur Lösung dieser Aufgabe besteht die Erfindung gemäß Anspruch 1, bei einer elektrischen
Anschlussklemme der eingangs genannten Art darin, dass die Kontaktfläche
an der Außenseite einer nach oben ragenden Stirnwand angeordnet
ist und dass der zweite Schenkel der Klemmfeder eine Führungsund
Klemmlasche vor der Kontaktfläche bildet.To achieve this object, the invention according to
Durch diese Ausgestaltung wird zum einen ein besonderes Isoliergehäuse zur Aufnahme der Klemmfeder und einer zusätzlichen Stromschiene überflüssig. Die neue Kontaktklemme kann in entsprechende Ausnehmungen eines in bekannter Weise aus Isoliermaterial bestehenden Gerätebechers eingesetzt werden. Sie lässt sich zum Anschluss von Lampen, Schaltern, Steckdosen mit unterschiedlichen Steckwinkeln und für Anschlüsse nach internationalen Standards sowie für die Telekommunikationstechnik verwenden. Die Anordnung einer Kontaktfläche, die in einfacher Weise nun eine Außenfläche des Gehäuses ist, ermöglicht in einfacher Weise den Kontakt mit einem Bandleiter.This configuration on the one hand becomes a special insulating housing to accommodate the clamping spring and an additional busbar superfluous. The new contact terminal can be used in corresponding Recesses of an existing in a known manner from insulating material Device cup are used. It can be used for connection of lamps, switches, sockets with different plug angles and for connections according to international standards as well as for telecommunications technology use. The arrangement of a contact area, which is now an outer surface of the housing in a simple manner contact with a strip conductor in a simple manner.
In Weiterbildung der Erfindung kann die Kontaktfläche des Gehäuses mit nach außen gedrückten Sicken versehen sein, durch die die Kontaktfläche aufgrund der Bildung von Berührungspunkten verkleinert wird, um vorgeschriebene Kriterien gegen unzulässige Temperaturerhöhung zu erfüllen.In a development of the invention, the contact surface of the housing be provided with beads pressed outwards through which the contact surface is reduced due to the formation of touch points prescribed criteria against inadmissible temperature increase fulfill.
Die Kontaktfläche kann durch zwei nach oben ragende Wandteile gebildet sein, die zwischen sich eine Öffnung zur Durchführung des zweiten Schenkels der Klemmfeder aufweisen, wobei der zweite Schenkel der Klemmfeder auf der von den ersten Federschenkeln abgewandeten Seite zwischen den beiden Wandteilen hindurchgeführt ist. The contact surface can be formed by two upstanding wall parts be between them an opening for carrying out the second Have leg of the clamping spring, the second leg of the Clamp spring on the side facing away from the first spring legs is passed between the two wall parts.
Der zweite Schenkel der Klemmfeder bildet an der von den zwei Federschenkeln abgewandten Seite die Klemmlasche, die aus dem Gehäuse herausragt und vor der Kontaktfläche angeordnet ist.The second leg of the clamping spring forms on that of the two spring legs side facing away from the clamping tab that comes out of the housing protrudes and is arranged in front of the contact surface.
Dabei ist es besonders einfach, wenn das Gehäuse rahmenförmig ausgebildet ist und aus einem überlappend zu einem Rahmen zusammengebogenen gestanzten Blech besteht, das an einer von einem Boden nach oben ragenden Stirnwand mit Öffnungen zum Einführen der Kabelenden und an der gegenüberliegenden Stirnwand mit der Kontaktfläche versehen ist. It is particularly simple if the housing is frame-shaped and is overlapped to form a frame punched sheet metal that is on one of a floor end wall protruding upwards with openings for inserting the cable ends and on the opposite end wall with the contact surface is provided.

In der Fig. 1 ist ein rahmenförmiges Gehäuse 1 aus elektrisch
leitendem Material, beispielsweise aus Messing dargestellt,
das auf einer seiner geschlossenen Seiten 2 mit zwei kreisrunden
Öffnungen 3, 3a versehen ist. Am Boden dieses Gehäuses
1 sind zwei sich in der Richtung der Pfeile IV verengende Einführungsbahnen
5 und 5a vorgesehen, zwischen denen eine Öffnung
4 vorgesehen ist. Die beiden Einführungsbahnen 5 und 5a
enden zur zweiten geschlossenen Seite des rahmenförmigen Gehäuses
1 hin in zwei nach oben ragende bügelförmige Wandteile,
die mit sickenförmigen Ausprägungen 7 versehen sind, die
sich nach außen erstrecken. Beide Wandteile sind zur Oberseite
hin rechtwinklig abgewinkelt und gehen in ein gemeinsames
Wandteil 8 über, das mit einem wiederum um 90° abgewinkelten
Endstück 9 etwas in den freien Raum des rahmenförmigen
Gehäuses 1 hereinragt.1 is a frame-
Der Wandteil 8 überlappt teilweise die Decke 10 des rahmenförmigen
Gehäuses 1 und ist mit dieser über Klemmhaken 11
verbunden, die von dem Deckenbereich 10 aus nach unten abgebogen
sind.The
Zwischen dem Deckenteil 10 und dem Wandteil 8 ist der Mittelteil
einer Klemmfeder 12 eingespannt, die aus zwei nebeneinander
liegenden U-förmigen Federschenkeln 12a besteht, von
denen jeder je einer der Einführungsbahnen 5 bzw. 5a zugeordnet
ist. Im Bereich der Klemmlaschen 11 vereinigen sich die
beiden Federschenkel 12a und gehen in einen zweiten etwa
rechtwinklig nach unten abgebogenen Federschenkel 13 über,
der seinerseits eine U-förmige Lasche bildet und ein um etwa
180° umgebogenes freies Ende 13a aufweist, das - siehe insbesondere
Fig. 2 - durch den zwischen den beiden Wandteilen
des Gehäuses 1 gebildeten Raum nach außen vorragt und mit
diesen Wandteilen eine Einführungstasche für einen aus Fig.
1 ersichtlichen Bandleiter 14 bildet. Dieser Bandleiter 14
wird, wie sich aus den Fig. 2 bis 4 ohne weiteres ergibt,
durch die Klemmwirkung der Lasche 13a gegen die Sicken 7 der
Wandteile gedrückt und kommt auf diese Weise in einen definierten
Kontakt zum Gehäuse 1 der Anschlußklemme. Da die
Wandteile in unmittelbarer elektrischer Verbindung mit den
Einführungsbahnen 5 und 5a stehen, gegen die die abisolierten
Enden 15 der Kabel 16 (Fig. 1) beim Einführen durch die Öffnungen
3, 3a durch die Wirkung des Schenkels 12a der Klemmfeder
12 gedrückt werden, kann eine einwandfreie elektrische
Verbindung zwischen dem Bandleiter 14 und den Kabeln 16 erzielt
werden.The middle part is between the
Erwähnt werden muß noch, daß zwischen den beiden Einführungsbahnen
5 und 5a des Gehäuses 1 ein nach oben ragender Steg 17
vorgesehen ist, der dazu dient ein Überkreuzen der Enden 15
der Anschlußkabel auch dann zu verhindern, wenn auf die Anschlußklemme
äußere Biegebewegungen einwirken.It must also be mentioned that between the two
Der Anschluß der beiden Kabelenden 15 erfolgt, wie aus Fig. 1
ohne weiteres ersichtlich wird, lediglich durch das Einschieben
der Enden 15 durch die Öffnungen 3 und 3a in die Einführungsbahnen
5 und 5a. Der Federschenkel 12a wird dabei in der
Einschieberichtung aufgebogen und sorgt anschließend zum einen
für das Andrücken der Kabelenden an die Einführungsbahnen
5 und 5a, zum anderen aber auch dafür, daß die Kabelenden
nicht wieder aus den Öffnungen 3 und 3a herausgezogen werden
können.The two
Soll dies aber geschehen, so kann durch die Öffnung 4, z.B.
mit einem Schraubendreher, einer der Schenkel 12a hochgebogen
werden, so daß dann ein Anschlußkabel entfernt werden kann,
ohne daß der sichere Halt des zweiten Kabels beeinflußt wird.
Um bei einer solchen Demontagebewegung das Überstrecken eines
der Federschenkel 12a zu vermeiden, ist der Wandteil 9 vorgesehen,
der als Anschlag gegen eine solche Überstreckung
dient.However, if this is to be done, opening 4, e.g.
with a screwdriver, one of the
Aus dem Vorstehenden wird ersichtlich, daß die neue Anschlußklemme
nur aus zwei Teilen zusammengesetzt ist, die sich
durch Stanz- und Biegeverfahren sehr einfach herstellen lassen
und dann in einem Arbeitsgang zusammengesetzt werden. Die
neue Anschlußklemme ist aufgrund ihrer Ausgestaltung dazu geeignet,
nahezu alle gängigen Anschlußkabel, z.B. eindrähtige
oder mehrdrähtige Kupferleiter bis 4mm2 Nennquerschnitt, aber
auch feindrähtige Kupferleiter mit Ultraschallverschweißung,
ebenfalls bis 4mm2 und feindrähtige Kupferleiter bis 2,5mm2
mit Aderendhülse aufzunehmen. Die Einführungsbahnen 5a sind,
wie den Fig. 1 und 4 zu entnehmen ist, mit scharfen Seitenkanten
18 versehen, die bei Andruck durch den Federschenkel
12a für einen guten Kontakt des eingeführten Kabelendes 15
mit dem Gehäuse 1 sorgen. Der Bandleiter 14 kann in einfacher
Weise von oben eingeschoben und in Kontaktklemmung gebracht
werden. Die neue Anschlußklemme eignet sich daher auch zur
Kontaktierung von Bandleitern.From the above it can be seen that the new connection terminal is composed of only two parts which can be produced very simply by punching and bending processes and are then assembled in one operation. Due to its design, the new connection terminal is suitable for accepting almost all common connection cables, e.g. single-wire or multi-wire copper conductors up to 4mm 2 nominal cross-section, but also fine-stranded copper conductors with ultrasonic welding, also up to 4mm 2 and fine-stranded copper conductors up to 2.5mm 2 with wire end ferrules. 1 and 4, the
