Description

Die Erfindung betrifft eine Anschlussklemme mit einem Gehäuse, insbesondere zum Aufrasten auf ein Trägerelement, wobei in das Gehäuse wenigstens eine oder mehrere Anschlusseinrichtungen zum Anschluss jeweils wenigstens eines Leiters eingesetzt ist bzw. sind.The invention relates to a terminal with a housing, in particular for latching onto a carrier element, wherein in the housing at least one or more connection means for connecting in each case at least one conductor is or are used.

Aus der DE 102 16 913 A1 ist eine Anschlußleiste mit mehreren Anschlüssen bekannt, die als Schraubanschlüsse ausgebildet sind.From DE 102 16 913 A1 a terminal block with a plurality of terminals is known, which are designed as screw connections.

Die GB 2 212 008 A zeigt ferner einen Stecker, bei dem Anschlußleitungen durch Durchgangslöcher von Steckkontakten gesteckt und umbiegend festgeklemmt werden.GB 2 212 008 A further shows a plug in which leads are inserted through through holes of plug contacts and clamped clamped.

Es besteht der Bedarf nach einer konstruktiv einfachen sowie leicht insbesondere auf einem Trägerelement zu montierenden Anschlussklemme, welche auf einfache Weise den Anschluss eines ersten dünneren Leiters und eines weiteren Leiters mit einem relativ zum ersten Leiter deutlich größeren Durchmesser, insbesondere eines Leiters mit einem mehrfachen Durchmesser ermöglichen soll. Es soll insbesondere möglich sein, auf einfache Weise eine Datenleitung mit einem Durchmesser von weniger als 1 mm, insbesondere weniger als 0,5 mm, mit einem Leiter mit einem mehrfachen Durchmesser von beispielsweise mehr als 1 oder 2 mm auf einfache Weise zu verbinden.There is a need for a structurally simple and easy to be mounted especially on a support member terminal, which easily allow the connection of a first thinner conductor and another conductor with a relative to the first conductor significantly larger diameter, in particular a conductor with a multiple diameter should. It should in particular be possible to easily connect a data line with a diameter of less than 1 mm, in particular less than 0.5 mm, with a conductor with a multiple diameter of, for example, more than 1 or 2 mm in a simple manner.

Die Lösung dieses Problems ist die Aufgabe der Erfindung.The solution to this problem is the object of the invention.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruch 1. Danach umfasst wenigstens eine der Anschlusseinrichtungen eine Stromschiene auf, die mit einem Durchgangsloch zum Durchstecken des einen Leiters versehen ist, wobei eine Klemmfeder derart auf die Stromschiene aufschiebbar ist, dass sie den durch das Durchgangsloch gesteckten Leiter an der Stromschiene umbiegend festklemmt.The invention solves this problem by the subject matter of claim 1. Thereafter, at least one of the connection means comprises a bus bar, which is provided with a through hole for the passage of a conductor, wherein a clamping spring is pushed onto the busbar such that it passes through the through hole clamped inserted conductor to the busbar bending over.

Damit ist es auf einfache Weise möglich, an die Stromschiene einen sehr dünnen Leiter anzuschließen, wobei die Stromschiene dann an ihrem vom Durchgangsloch abgewandten Bereich in an sich bekannter Weise mit einem beliebigen sonstigen Anschluss zum Anschluss eines weiteren Leiters mit einem größeren Durchmesser versehen sein kann. So bietet es sich insbesondere an, die Anschlussklemme als Durchgangsklemme auszubilden und die Stromschiene ferner noch mit einem oder mehreren Zugbügelanschlüssen, Zugfederanschlüssen, IDC-Anschlüssen und/oder Direktsteckanschlüssen zu versehen.This makes it possible in a simple manner to connect to the busbar a very thin conductor, the busbar can then be provided at its remote from the through hole area in a conventional manner with any other connection for connecting a further conductor with a larger diameter. So it is particularly appropriate to form the terminal as a feed-through terminal and also to provide the busbar with one or more Zugbügelanschlüssen, Zugfederanschlüssen, IDC connections and / or direct plug connections.

Wird als weitere Anschlusseinrichtung ein Zugbügelanschluss gewählt, weist dieser zweckmäßig den Zugbügel mit der Stromschiene und der Klemmschraube zum Anschluss des ersten Leiters größeren Durchmessers auf, wobei sich an die Stromschiene des Zugbügels ein freier Stromschienenschenkel anschließt, der mit dem Durchgangsloch zum Durchstecken des zweiten, vormontierbaren Leiters geringeren Durchmessers versehen ist.If a drawbar connection is selected as a further connection device, this expediently has the drawbar with the busbar and the clamping screw for connecting the first conductor of larger diameter, wherein the busbar of the drawbar is followed by a free busbar leg, which connects with the through-hole for inserting the second, premountable Ladder is provided with a smaller diameter.

Nach einer vorteilhaften Variante ist die Klemmfeder tulpenartig ausgebildet und mittels Stegen des Trägerelements, welche bei der Montage in Schlitze des Gehäuses eingreifen, auf die Stromschiene bei der Montage auf dem Trägerelement aufschiebbar. Bei dem weiteren Leiter kann es sich beispielsweise um eine sehr dünne Datenleitung am Trägerelement handeln, die erst bei der Montage in das Durchgangsloch eingesteckt wird. Sodann wird das Gehäuse auf das Trägerelement aufgesetzt und dort verrastet, wobei die Klemmfeder die dünne Datenleitung am Trägerelement festklemmet. In die weitere Anschlusseinrichtung kann dann ein Leiter mit einem wesentlich größeren Durchmesser - z.B. aus einer Hausinstallation - eingeführt werden. Es ist somit nicht nur auf einfache Weise möglich, den sehr dünnen Leiter problemlos an sich zu kontaktieren sondern es wird auch auf einfachste Weise möglich, den sehr dünnen Leiter mit einem deutlich dickeren Leiter zu verbinden.According to an advantageous variant, the clamping spring is tulip-like and by means of webs of the support element, which engage in the assembly in slots of the housing, pushed onto the busbar during assembly on the support member. The further conductor can be, for example, a very thin data line on the carrier element, which is inserted into the through hole only during assembly. Then, the housing is placed on the support member and locked there, wherein the clamping spring clamps the thin data line to the support member. In the further connection device can then be a conductor with a much larger diameter - for example, from a domestic installation - introduced. It is thus not only possible in a simple manner to easily contact the very thin conductor but it is also possible in the simplest way to connect the very thin conductor with a much thicker conductor.

Der Aufbau der Anschlussklemme ist konstruktiv einfach und die Montage ohne Spezialwerkzeug nach Art einer setzenden Bestückung des Trägerelementes auf einfache Weise auch automatisiert möglich.The structure of the terminal is structurally simple and the assembly without special tool in the manner of a placing placement of the support element in a simple way and automatically possible.

Besonders bevorzugt weist das Gehäuse kostengünstig einen zweiteiligen Aufbau mit einem Gehäuseoberteil und einem Gehäuseunterteil auf, die miteinander verrastbar sind.Particularly preferably, the housing has a cost-effective two-part construction with an upper housing part and a lower housing part, which can be locked together.

Zweckmäßig ist das Gehäuseoberteil an seiner zum Gehäuseunterteil gewandten Seite offen ausgelegt und weist wenigstens eine oder mehrere Zwischenwände auf, welche den Raum im Gehäuseunterteil je nach Anzahl der Anschlusseinrichtungen - z.B. je nach Auslegung 2, 3 oder mehr - in eine entsprechende Zahl von Kammern unterteilen. Dabei ist in jede der Kammern eine der Anschlusseinrichtungen als Durchgangsanschluss eingesetzt. Sowohl die Zahl der Kammern als auch die der Anschlussrichtungen kann damit zur Realisierung verschieden vieler Anschlüsse auf einfache Weise variiert werden.Suitably, the upper housing part is designed to be open on its side facing the lower housing part and has at least one or more partitions which, depending on the number of connecting devices - e.g. depending on the design 2, 3 or more - subdivide into a corresponding number of chambers. In this case, one of the connection devices is inserted as a passage connection in each of the chambers. Both the number of chambers and the connection directions can thus be varied in a simple manner to realize different numbers of connections.

Vorteilhaft ist die Stromschiene in ihrem oberen Bereich u-förmig gebogen, wobei der eine der beiden Längsschenkel des U in den Zugbügel eingreift und wobei sich an den an den anderen der beiden Längsschenkel der Schenkel mit dem Durchgangsloch des U um 90° nach außen abgebogen anschließt.Advantageously, the busbar is bent in a U-shaped manner in its upper region, wherein one of the two longitudinal limbs of the U engages in the clamping yoke and is connected to the other of the two longitudinal limbs of the legs with the through hole of the U bent by 90 ° outwards ,

Es ist auch denkbar, in kostengünstiger Weise mit dem Grundschenkel der u-förmigen Stromschiene einstückig - insbesondere in Stanz-/Biegetechnik - jeweils einen weiteren Kontakt, insbesondere einen Tulpenkontakt, zu verbinden.It is also conceivable, in a cost-effective manner in one piece with the base leg of the U-shaped busbar - in particular in stamping / bending technology - each to connect another contact, in particular a tulip contact.

Vorzugsweise ist an einer der Seitenwände des Gehäuseoberteils ferner je Zugbügel in kompakter Bauart je eine Einführöffnung zum Einführen eines Leiters in den Zugbügel und eine weitere Einführöffnung zum Einführen eines Leiters in das Durchgangsloch ausgebildet.Preferably, one insertion opening for inserting a conductor into the clamping yoke and a further insertion opening for inserting a conductor into the through-hole are each formed on each of the side walls of the housing upper part, depending on the drawbar in a compact design.

Zur Festlegung und Fixierung des Gehäuses an dem Trägerelement sind weiter in einfacher Weise vorkragende Nasen vorgesehen, welche zum Hintergriff eines entsprechenden Hinterschnittes in einem Aufnahmeschacht des Trägerelementes dienen, wobei ein Hintergriff an der gegenüberliegenden Seite des Gehäuses mittels eines Rasthakens am Trägerelement erfolgt, der am Gehäuse verrastet ist, wenn das Gehäuse nach dem Einschieben der Nase in die Hinterschnitte auf das Trägerelement aufschwenkt.For fixing and fixing of the housing to the support member projecting lugs are further provided in a simple manner, which serve to engage behind a corresponding undercut in a receiving shaft of the support element, wherein a rear grip on the opposite side of the housing by means of a latching hook on the support element takes place on the housing is latched when the housing swings after the insertion of the nose in the undercuts on the support member.

Weitere vorteilhafte Ausgestaltungen sind den übrigen Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in the remaining subclaims.

In die Zugbügel 7 greift jeweils eine Stromschiene 10 ein, welche in ihrem oberen Bereich u-förmig gebogen ist, wobei der eine der beiden Längsschenkel 11 des U in den Zugbügel 6 eingreift und wobei an den an den anderen der beiden Längsschenkel 12 des U ein weiterer um 90° nach außen abgebogener Schenkel 13 angeformt ist, welcher im Gehäuseoberteil nach unten zur offenen Seite (bzw. zum Gehäuseunterteil 3 hin) hin ausgerichtet ist.In the yoke 7 engages in each case a busbar 10, which is bent in its upper region u-shaped, wherein one of the two longitudinal legs 11 of the U engages in the yoke 6 and wherein at the other of the two longitudinal legs 12 of the U a further bent by 90 ° outwards leg 13 is formed, which is aligned in the upper housing part down to the open side (or to the lower housing part 3) out.

Dieser Schenkel 13 weist als weiteren Anschlusskontakt der Anschlusseinrichtung 34 ein Durchgangsloch 14 zum Durchstecken eines sehr dünnen Leiters 20 (Fig. 2) auf, wobei der Schenkel 13 in seiner Montagestellung in eine tulpenartige Klemmfeder 15 eingreift (Schnitt der Fig. 3b).This leg 13 has, as a further connection contact of the connection device 34, a through hole 14 for the passage of a very thin conductor 20 (FIG. 2), wherein the leg 13 engages in its mounting position in a tulip-like clamping spring 15 (section of Fig. 3b).

An den Grundschenkel 26 des U schließt sich ferner einstückig (z.B. in Stanz-/Biegetechnik) hier beispielhaft jeweils ein Tulpenkontakt 16 an, dessen Einführöffnung 17 neben dem Zugbügel im Gehäuse liegt, wobei jeweils neben der Öffnung 9 für die Klemmschrauben 8 der Zugbügel 7 eine weitere Öffnung 30 (Fig. 1a) vorgesehen ist, welche zum Einstecken eines weiteren Leiters in den Tulpenkontakt 16 dient.To the base leg 26 of the U further integrally (eg in stamping / bending) here is a tulip contact 16, whose insertion 17 is adjacent to the drawbar in the housing, in each case adjacent to the opening 9 for the clamping screws 8 of the yoke 7 a further opening 30 (FIG. 1 a) is provided, which serves for inserting a further conductor into the tulip contact 16.

An einer der Seitenwände des Gehäuseoberteils 2 ist ferner je Zugbügel 7 eine Einführöffnung 18 zum Einführen eines Leiters mit größeren Durchmesser in den Zugbügel 7 ausgebildet.On one of the side walls of the housing upper part 2, an insertion opening 18 for inserting a conductor with a larger diameter into the clamping yoke 7 is furthermore formed per clamping yoke 7.

Unterhalb der Einführöffnung 18 liegt eine weitere Einführöffnung 19 zum Einführen des sehr dünnen Leiters 20 in das Durchgangsloch 14.Below the insertion opening 18 is another insertion opening 19 for insertion of the very thin conductor 20 in the through hole 14th

Jede Anschlusseinrichtung 34 weist damit nach dem Ausführungsbeispiel der Fig. 1 bis 3 drei Anschlusskontakte für Leiter (und/oder Stecker) auf, welche leitend miteinander verbunden werden: einen der Zugbügel 7 , einen der Tulpenkontakte 16 (Einführrichtung senkrecht zu_der des Zugbügels) und das Durchgangsloch 14 mit der Klemmfeder 15.Thus, according to the exemplary embodiment of FIGS. 1 to 3, each connection device 34 has three connection contacts for conductors (and / or plugs) which are conductively connected to one another: one of the tension yokes 7, one of the tulip contacts 16 (insertion direction perpendicular to the tension yoke) and Through hole 14 with the clamping spring 15th

In das Durchgangsloch 14 wird bei der Montage das eine Ende des dünnen Leiters 20 eingesteckt, der mit der u-förmigen Klemmfeder 15 an dem Schenkel 14 in diesem Bereich beim Einstecken ebenfalls in eine U-Form innerhalb der Klemmfeder 15 umgebogen und damit fixiert wird (Fig. 2a, Fig. 3). Der Leiter 20 steht dabei aus der Einführöffnung 19 mit einem freien Ende vor, das mit einer Elektronik am Trägerelement verbunden sein kann.In the through hole 14, the one end of the thin conductor 20 is inserted during assembly, which is also bent with the U-shaped clamping spring 15 on the leg 14 in this area during insertion into a U-shape within the clamping spring 15 and thus fixed ( Fig. 2a, Fig. 3). The conductor 20 protrudes from the insertion opening 19 with a free end, which may be connected to an electronics on the support element.

Zur Fixierung des Gehäuses 1 an einem Trägerelement 24 (wie ein Gerätegehäuse oder ein Leiterplatten-Aufnahmegehäuse) dienen auf der einen Seite des Gehäuses 1 zwei seitlich vorkragende Nasen 21, welche zum Hintergriff eines entsprechenden Hinterschnittes 22 in einem Aufnahmeschacht 23 des Trägerelementes 24 dienen.For fixing the housing 1 to a carrier element 24 (such as a device housing or a circuit board receiving housing) serve on one side of the housing 1 two laterally projecting lugs 21, which serve to engage behind a corresponding undercut 22 in a receiving shaft 23 of the support member 24.

Ein Hintergriff an der gegenüberliegenden Seite wird an einem Absatz 35 am Gehäuse neben zwei vorkragenden Einführtrichter 25 an der Einführöffnung 19 zum Durchgangsloch 14 realisiert, welche einen Rasthaken 31 am Trägerelement 24 hintergreifen, wenn das Gehäuse 1 nach dem Einschieben der Nase 21 in die Hinterschnitte 23 auf das Trägerelement 24 aufgeschwenkt wird (Fig. 2b).A rear grip on the opposite side is realized on a shoulder 35 on the housing next to two projecting insertion funnel 25 at the insertion opening 19 to the through hole 14, which engage behind a latching hook 31 on the support member 24, when the housing 1 after insertion of the nose 21 in the undercuts 23rd is pivoted on the carrier element 24 (Fig. 2b).

Hierbei greifen Stege 32 am Trägerelement 24 in Schlitze 33 des Gehäuseunterteiles 3 ein, welche derart ausgelegt und angeordnet sind, dass sie die Klemmfedern 15 aus einer Vormontagestellung auf die Schenkel 13 der Stromschiene 10 aufschieben, wobei sie den sehr dünnen Leiter 20 - z.B. 0,3mm - in einfacher Weise entsprechend umbiegen und klemmend gesichert vormontieren (Fig. 2c, Fig. 3 a - c).In this case, webs 32 on the carrier element 24 engage in slots 33 of the housing lower part 3, which are designed and arranged such that they push the clamping springs 15 from a pre-assembly position on the legs 13 of the busbar 10, wherein the very thin conductor 20 -. 0.3 mm - bend in a simple manner accordingly and preassembled secured in a clamping manner (FIGS. 2 c, 3 a - c).

Die Ausführungsbeispiele der Fig. 4 bis 6 unterscheiden sich von denen der Fig. 1 bis 3 dadurch, dass keine Tulpenkontakte an die Grundschenkel 26 der U-förmigen Stromschienen angeformt sind. Damit verringert sich die Anzahl der Anschlußkontakte je Kammer um eins, was aber in vielen Anwendungsfällen den Erfordernissen genügt.The embodiments of FIGS. 4 to 6 differ from those of FIGS. 1 to 3 in that no tulip contacts are formed on the base legs 26 of the U-shaped busbars. This reduces the number of connection contacts per chamber by one, but this satisfies the requirements in many applications.

Zur einfachen Realisierung eines Prüfabgriffs ist das Gehäuseoberteil 2 dafür nach Fig. 4 - 6 im Bereich jeder Kammer mit einem Durchbruch 36 versehen, an dem die hier in der Durchbruch ragenden Stromschienen 10 mit einer Prüfspitze oder dgl. kontaktierbar sind.For simple realization of a Prüfabgriffs the upper housing part 2 is provided for this according to Fig. 4-6 in the region of each chamber with an opening 36 at which the projecting here in the breakthrough conductor rails 10 with a probe or the like.
