Aus der DE 26 09 291 C2 ist eine Verbindungsklemme mit den Merkmalen "a" bis "c" des Anspruches 1 bekannt.DE 26 09 291 C2 discloses a connecting terminal with the features "a" to "c" of claim 1 known.
Eine gattungsgemäße Verbindungsklemme ist aus der DE 44 44 438 AI bekannt. Die
in dieser Schrift dargestellte schraubenlose Anschlußklemme hat sich zwar an sich
bewährt. Wünschenswert sind eine Verbesserung der Handhabung und des konstruktiven
Aufbaus für den Anschluß von jeweils mehr als einem Leiter an einer oder beiden
Stirnseiten der Klemme.A generic connector is known from
Nach der Aufgabe der Erfindung sollen die Leiter auf engem Raum leicht in die Leuchtenklemme einführbar sein, ohne daß bereits in die Leuchtenklemme eingeführte Leiter das Einführen weiterer Leiter behindern.According to the object of the invention, the ladder should be easy in the tight space Luminaire clamp can be inserted without having already been inserted into the luminaire clamp Impede the introduction of additional conductors.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruches 1.The invention solves this problem by the subject matter of claim 1.
Durch das Schlitzen der Blattklemmfeder ist es vollkommen unproblematisch möglich, zunächst einen ersten Leiter in der Klemme festzulegen und dann den zweiten Leiter einzuschieben, ohne sich beim Einführen des zweiten Leiters der erste Leiter aus der Klemmstelle zwischen der Blattklemmfeder und dem Metallkontaktrahmen lösen könnte. Der Vorsprung am Metallkontaktrahmen führt ferner die beiden von einer ersten Seite her einzuführende Leiter derart parallel zueinander bzw. sogar etwas auseinander, daß von der anderen Seite ein weiterer Leiter problemlos mittig zwischen die beiden von der ersten Seite her eingeführten Leiter geschoben werden kann.By slitting the leaf clamp spring, it is completely unproblematic possible First define a first conductor in the terminal and then the second conductor to insert without the first conductor coming out of the Loosen the clamping point between the leaf clamping spring and the metal contact frame could. The protrusion on the metal contact frame also guides the two of a first Side conductors to be inserted parallel to one another or even slightly apart, that from the other side another conductor easily between the middle two conductors inserted from the first side can be pushed.
Eine Senkung des Herstellaufwandes sowie der Herstellkosten der Klemme ist ferner auf einfache Weise dadurch möglich, daß das Gehäuse als Spritzgußteil aus Kunststoff ausgeführt ist, welches ein Gehäusebasisteil und einen mit dem Gehäusebasisteil über ein Filmscharnier verbundenen, schwenkbaren Deckelteil aufweist, der am Gehäusebasisteil verrastbar ist. Das Filmscharnier sorgt auf eine einfache Weise für eine Unverlierbarkeit des Deckelteils bei kostengünstiger Herstellung.A reduction in the manufacturing effort and the manufacturing costs of the terminal is also possible in a simple manner that the housing as an injection molded part made of plastic is executed, which is a housing base part and with the housing base part has a hinged cover part connected to a film hinge, which can be locked on the housing base part. The film hinge ensures easy Way for captivity of the cover part with inexpensive manufacture.
Eine weitere besonders bevorzugte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß der Metallkontaktrahmen zwei Einführschlitze für an der Innenseite des Deckels ausgebildete Vorsprünge aufweist, welche derart geformt sind, daß sie beim Betätigen des Deckels den Klemmschenkel der Blattklemmfeder synchron niederdrücken und ein Gegenlager für die Klemmschenkel der Blattklemmfeder bilden. Durch diesen einfachen Betätigungsmechanismus kann der beim Stand der Technik erforderliche Kipphebel zur Betätigung der Klemme fortgelassen werden.Another particularly preferred embodiment of the invention is distinguished characterized in that the metal contact frame has two insertion slots for on the inside of the cover has projections which are shaped in such a way that they synchronize the clamping leg of the leaf clamping spring when actuating the lid press down and a counter bearing for the clamping legs of the leaf clamping spring form. With this simple actuation mechanism, the stand the rocker arm required to operate the clamp can be omitted.

Die Verbindungsklemme nach Fig. 1 weist ein im wesentlichen rechteckiges Gehäuse
2 aus Kunststoff auf, welches an einer ersten Stirnseite 4 der beiden einander
gegenüberliegenden Stirnseiten 4, 6 des Gehäuses mit zwei direkt nebeneinander
liegenden Einführöffnungen 8a, 8b für zwei elektrische Leiter sowie an der gegenüberliegenden
Stirnseite 6 mit einer einzigen weiteren Einführöffnung 10 für einen
weiteren elektrischen Leiter versehen ist.1 has a substantially
Unterhalb der Einführöffnungen 8, 10 für die elektrischen Leiter ist an der Stirnseite
6 eine Prüfabgriffsöffnung 12 vorgesehen. Eine weitere Prüfabgriffsöffnung 13 ist
an der anderen Stirnseite 4 ausgebildet (Fig. 2d).Below the
Die Oberseite des Gehäuses 2 ist als Deckelteil 14 ausgebildet, welches über ein
zweiteiliges Filmscharnier 16 mit dem übrigen Gehäuse 2 verbunden ist. Das Dekkelteil
14 gibt im aufgeklappten Zustand der Fig. 2a, 2b einen ebenfalls im wesentlichen
rechtwinkligen Einführraum 18 für die Metallteile der Verbindungsklemme
frei (Fig. 2a).The top of the
Diese Metallteile umfassen eine im wesentlichen in eine U-Form gebogene Blattklemmfeder
20 - deren Klemmschenkel 22, 24 nach innen zueinander hin gebogen
sind - und einen Metallkontaktrahmen 26 zur Aufnahme der Blattklemmfeder 20.
Der Metallkontaktrahmen 26 steht an seinen beiden Stirnseiten und an einer Längsseite
nach außen offen, derart, daß von der Längsseite her die Blattklemmfeder 20
in den Metallkontaktrahmen 26 einsetzbar ist und derart, daß die Leiter von den
Stirnseiten her zwischen die Klemmschenkel 22,24 und die Innenwandung des
Metallkontaktrahmens 26 führbar sind.These metal parts comprise a leaf clamp spring which is essentially bent into a U-shape
20 - the
Der zur Stirnseite 4 mit den zwei Einführöffnungen 8a, 8b hin weisende Klemmschenkel
24 der Blattklemmfeder ist (parallel zur Bildebene der Fig. 1; siehe auch
Fig. 3) geschlitzt ausgebildet, so daß die dabei entstehenden zwei Klemmschenkelabschnitte
24a, 24b unabhängig voneinander bewegbar sind. Der Schlitz 28 liegt
in einer Ebene, die mittig zwischen den beiden Einführöffnungen 8a, 8b verläuft.
Hierdurch können zwei Leiter in vorteilhafter Weise unabhängig voneinander in
den beiden Einführöffnungen 24a, 24b festgeklemmt werden. Auf der gegenüberliegenden
Stirnseite wird dagegen nur ein Leiter festgeklemmt, so daß der zugehörige
Klemmschenkel 22 nicht geschlitzt ausgebildet ist.The clamping leg pointing towards the end face 4 with the two
An der zum Deckelteil 14 weisenden Seite weist der Metallkontaktrahmen 26 zwei
Einführschlitze 30 für zwei an der Innenseite des Deckels 14 ausgebildete Vorsprünge
32a, 32b auf, die jeweils Gegenlager für die zwei Klemmschenkelabschnitte
24a und 24b der Blattklemmfeder 20 bilden und die derart geformt sind,
daß sie beim Niederdrücken des Deckelteils 14 den Klemmschenkel 24 der Blattklemmfeder
20 synchron niederdrücken (Fig. lb), so daß die Leiter 46, 48 leichter
in die Leuchtenklemme eingesteckt und aus dieser herausgezogen werden können.
Hierdurch wird das in der DE 26 09 291 vorgesehene Wippenhebelelement, welches
zudem nur einen Betätigungsvorsprung aufwies und daher relativ leicht zu einer
Seite hin kippte, auf einfache Weise eingespart. Seitenwände 34 mit Hintergriffen
36 verriegeln das Deckelteil 14 an Hinterschnitten 38 des Gehäusebasisteils 40.The

Der Metallkontaktrahmen 26 weist danach an seiner den Klemmschenkelabschnitten
24a und 24b der Blattklemmfeder 20 gegenüberliegenden Seite 42 einen mittigen
Vorsprung 44 auf, welcher die zwischen die Blattklemmfeder 20 und den Metallkontaktrahmen
eingesetzten zwei Leiter 46, 48 der Kabel 46', 48' voneinander
beabstandet, so daß der von der gegenüberliegenden Seite eingesetzte Leiter 50 oder
Stecker mittig zwischen die beiden zueinander parallelen Leiter 46, 48 führbar ist.
Diese Art der Anordnung erleichtert das Einführen der Leiter 46, 48 in die (Leuchten-)Klemme
erheblich. The
Wie ferner zu erkennen, ist der Metallkontaktrahmen 26 mit drei inneren Anschlägen
52a, 52b, 52c für die in die Verbindungsklemme einführbaren Leiter 46 -50
versehen, die hier als drei vom Metallkontaktrahmen 26 nach innen vorgebogene
Lappen ausgebildet sind. Seitlich zu den Einführöffnungen für die Leiter 46 - 50
versetzt sind am Metallkontaktrahmen 26 zudem zur Innenseite hin Vorsprünge
bzw. Sicken 54a, 54b, 54c ausgebildet, welche als Anlage- und Kontaktierungsbereiche
für die zwischen der Blattklemmfeder 20 und dem Metallkontaktrahmen 26
festklemmbaren Leiter 46, 48, 50 dienen.As can also be seen, the
Fig. 3c veranschaulicht ferner, daß die Blattklemmfeder in ihren Anlagebereichen
für die Leiter 46 und 48 eine der Leiterform angepaßte Kontur 56 aufweist, was die
Positionierung dieser Leiter in der Leuchtenklemme vereinfacht. An der Leuchtenseite
ist die Blattklemmfeder 20 im Bereich des Klemmschenkels 22 in den beiden
äußeren Bereichen, abgekröpft ausgebildet. Der eigentlichen Klemmschenkel 22
weist eine Breite auf, welche im wesentlichen dem Durchmesser des festzuklemmenden
Leiters 50 entspricht.Figure 3c further illustrates that the leaf clamp spring is in its abutment areas
for the
Das Ausführungsbeispiel der Fig. 4 ähnelt weitgehend dem der Fig. 3. Zusätzlich ist
aber die Blattklemmfeder 20 an ihrer von den Leiteranlageflächen des Gehäuses 2
abgewandten Außenseite mit einer Ausnehmung 58 versehen, durch welche ein
stiftartiges Anschlagelement 60 in die Blattklemmfeder 20 einschiebbar ist (beim
Zusammenführen des Gehäuses 2), welches die Blattklemmfeder 20 weitestgehend
durchsetzt und sich bis in die unmittelbare Nähe des unteren, mittleren Anschlages
52c erstreckt.The embodiment of FIG. 4 is largely similar to that of FIG. 3
but the
Das Anschlagelement 60 wird vorzugsweise als stiftartiger, einstückiger Ansatz des
Gehäuses 2 ausgebildet und dient insbesondere zur (ergänzenden) Begrenzung der
Bewegung des Leiters 50 (insbesondere einer Litze), vorzugsweise dann, wenn dieser
einen relativ kleinen Durchmesser aufweist. Hierzu ist es an seinem zum Anschlag
52c weisenden Ende - an der zum Leiter 50 weisenden Seite - mit einer Aufnahme
62 für das Ende des Leiters 50 versehen.The
Bei Leitern 50 mit einem größeren Durchmesser wird dagegen nach Fig. 5 und 6 die
Bewegung des Leiters 50 bzw. die Bewegung der den Leiter 50 umgebenden Isolierung
64 durch einen seitlich an das Gehäuse 2 vorzugsweise einstückig angeformten
Fortsatz 66 mit einer trichterförmigen Einführung 68 begrenzt, so daß die Isolierung
des Leiters nur bis zum Ende der Einführung 68 schiebbar ist. Vorzugsweise wird
die trichterförmige Einführung 68 ferner asymmetrisch derart ausgebildet und am
Gehäuse 2 angeordnet, daß der Leiter 50 sicher gegen die Stromschiene (bzw. den
Metallkontaktrahmen 26) gedrückt und gut geführt wird. In the case of
