Description

Die Erfindung betrifft Vorrichtungen gemäß dem Oberbegriff des Anspruchs 1. Diese Vorrichtungen sind dazu bestimmt, eine oder mehrere Abzweigleitungen an ein Flachkabel anzuschließen.The invention relates to devices according to the preamble of claim 1. These devices are intended one or more branch lines to a flat cable to connect.

Derartige Anschlußvorrichtungen sind bekannt aus der DE-C 22 06 187 oder der DE-A 44 02 837. Diese bekannten Vorrichtungen umfassen ein quaderförmiges Gehäuse aus Isoliermaterial mit einem Basisteil, einem abnehmbaren Boden und einem abnehmbaren Deckel. Zwischen Basisteil und Boden ist ein Aufnahmeraum gebildet, in den das Flachkabel unverwechselbar eingelegt werden kann. Entsprechend der Anzahl der Leiter des Flachkabels sind im Basisteil Kontaktelemente angeordnet. Diese umfassen zunächst eine Kontaktschraube mit Kontaktspitze zum Kontaktieren der Leiter des Flachkabels durch dessen Isolierung hindurch sowie Kontaktklemmen zum Festklemmen der Leiter der Abzweigleitung. Die Kontaktklemmen sind durch entsprechende Öffnungen im Basisteil hindurch zugänglich, wobei sich diese parallel zu den Kontaktschrauben erstrecken.Such connection devices are known from the DE-C 22 06 187 or DE-A 44 02 837. These known Devices comprise a cuboid housing Insulating material with a base part, a removable bottom and a removable lid. Between base part and floor is a recording room in which the flat cable can be inserted unmistakably. According to the Number of conductors of the flat cable are in the base part Contact elements arranged. These initially include one Contact screw with contact tip for contacting the Conductor of the flat cable through its insulation as well as contact clamps for clamping the conductors of the Branch line. The contact terminals are by appropriate Openings in the base part are accessible through them extend parallel to the contact screws.

Die Befestigung der Leiterenden der Abzweigleitung erfolgt mit Hilfe von Klemmschrauben, die von der rechten und linken Längsseitenwand des Basisteils aus zugänglich sind. Dadurch muß der Installateur, nachdem er das Flachkabel eingelegt, den Boden aufgeschoben, das Flachkabel durch Eindrehen der Kontaktschrauben kontaktiert und die abisolierten Drahtenden der Abzweigleitung eingeführt hat, die Anschlußvorrichtung zunächst um 90° auf die eine Seite drehen, um die einen Klemmschrauben anzuziehen, und anschließend um 180° auf die andere Längsseite, um die restlichen Klemmschrauben anzuziehen. Dies ist umständlich und zeitraubend. The conductor ends of the branch line are attached with the help of clamping screws from the right and left Longitudinal side wall of the base part are accessible. Thereby After installing the flat cable, the installer must pushed the floor, the flat cable by screwing the Contact screws contacted and the stripped wire ends the branch line has introduced the connecting device first turn 90 ° on one side, around the one Tighten the clamping screws, and then by 180 ° on the other long side to the remaining clamping screws to attract. This is cumbersome and time consuming.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Anschlußvorrichtung der eingangs genannten Art derart weiterzuentwickeln, daß ihre Montage und Demontage am Flachkabel einerseits und insbesondere die Montage und Demontage der Abzweigleitung andererseits erheblich schneller durchgeführt werden können.The present invention is therefore based on the object a connecting device of the type mentioned above to further develop that their assembly and disassembly on Flat cable on the one hand and in particular the assembly and Dismantling of the branch line on the other hand considerably can be done faster.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1.This object is achieved by a device with the Features of claim 1.

Dank der zum Flachkabel hin offenen Vertiefungen, in denen die Kontaktklemmen formschlüssig sitzen, ist die Montage der Kontaktklemmen sehr erleichtert, da diese in einfachster Weise von unten in das Basisteil eingesteckt werden können. Sobald die Kontaktschrauben eingedreht sind, sitzen die Kontaktklemmen unverlierbar im Oberteil.Thanks to the recesses open towards the flat cable, in which the contact clamps sit positively, is the assembly of the Contact clamps very relieved as they are the simplest Can be inserted into the base part from below. As soon as the contact screws are screwed in, they sit Contact clamps cannot be lost in the upper part.

Dank der offenen Vertiefungen lassen sich die Kontaktklemmen bei Bedarf auch wieder herausnehmen und umstecken. Dies ist insbesondere dann von Vorteil, wenn nur drei der üblicherweise fünf Leiter des Flachkabels zu kontaktieren sind. In einem solchen Fall können zwei der Vertiefungen im Basisteil der Anschlußvorrichtung leer bleiben.Thanks to the open recesses, the contact terminals can be if necessary, take it out and reposition it. This is particularly advantageous if only three of the usually to contact five conductors of the flat cable are. In such a case, two of the depressions in the Base part of the connection device remain empty.

Gemäß einer ersten Weiterbildung der Erfindung sind die Kontaktklemmen schraubenlose Klemmen, nur mittels Werkzeug zu öffnen und aus Blech gebogen. Dadurch lassen sich nicht nur Drähte, sondern auch Litzen sicher und dauerhaft kontaktieren. Dies gilt insbesondere dann, wenn gemäß einer vorteilhaften Ausgestaltung der Erfindung die Kontaktklemmen mit einer Käfigzugfeder ausgerüstet sind.According to a first development of the invention Contact terminals screwless terminals, only with a tool to open and bent from sheet metal. This does not allow only wires, but also stranded wires safely and permanently to contact. This applies in particular if, according to a advantageous embodiment of the invention, the contact terminals are equipped with a cage tension spring.

Gemäß einer Ausgestaltung der Erfindung ist die Kontaktschraube in einer massiven Schraubhalterung geführt, die ihrerseits mit einer Kontaktklemme verbunden, beispielsweise verschweißt ist. Hier findet die Kontaktschraube eine großflächige Führung in der Schraubhalterung mit einem entsprechend geringen Übergangswiderstand.According to one embodiment of the invention Contact screw guided in a solid screw holder, which in turn are connected to a contact terminal, for example is welded. Here you will find the Contact screw a large-area guide in the Screw bracket with a correspondingly low Contact resistance.

Besonders bevorzugt ist jedoch eine Ausführungsform, bei der die Kontaktschraube in einer U-förmigen, aus Blech gebogenen Schraubhalterung geführt ist, wobei diese mit der Kontaktklemme einstückig ist. Dies erleichtert und verbilligt zunächst die Herstellung der Kontaktklemmen. Wie gewünscht sitzt die Kontaktschraube sehr fest in der Schraubhalterung und hat einen geringen Übergangswiderstand. Da auch die Schraubhalterungen formschlüssig in korrespondierenden, zum Flachkabel hin offenen Vertiefungen des Basisteils stecken, können die U-Schenkel seitlich nicht ausweichen.However, an embodiment in which the contact screw in a U-shaped, bent from sheet metal Screw bracket is guided, this with the Contact terminal is in one piece. This facilitates and First of all, the manufacture of the contact terminals is cheaper. How if desired, the contact screw sits very firmly in the Screw bracket and has a low contact resistance. Since the screw brackets also fit in corresponding depressions open towards the flat cable of the base part, the U-legs cannot laterally dodge.

Gemäß einer vorteilhaften Ausgestaltung ist in die beiden U-Schenkel der Schraubhalterung jeweils ein der Kontaktschraube entsprechendes Teilgewinde eingeschnitten. Dadurch wird nicht nur der Halt der Kontaktschraube verbessert, sondern auch eine Druckkraft auf die U-Schenkel und auf das diese umgebende Kunststoffmaterial des Basisteils verhindert, so daß es nicht zu dem gefürchteten Ausweichen des Kunststoffs und damit zur Lockerung der Kontaktschraube kommen kann.According to an advantageous embodiment, the two U-leg of the screw bracket one of each Contact screw cut corresponding part thread. This will not only hold the contact screw improved, but also a compressive force on the U-leg and on the plastic material surrounding it Prevents base part so that it is not the dreaded Dodge the plastic and thus to loosen the Contact screw can come.

Gemäß einer Weiterbildung der Erfindung befindet sich neben der Drahteinführungsöffnung eine Öffnung zum Einführen des Werkzeugs, mit dem die Kontaktklemmen bzw. Käfigzugfedern gelöst werden.According to a development of the invention is located next to the wire insertion opening, an opening for inserting the Tool with which the contact clamps or cage clamp springs be solved.

Vorteilhafterweise sind die Kontaktklemmen in Gruppen zusammengefaßt, entsprechend der Ausführung der Flachkabel.The contact terminals are advantageously in groups summarized, according to the design of the flat cable.

Vorzugsweise erstrecken sich die Kontaktklemmen parallel zum Flachkabel. Dies führt zu einer schmalen, langgestreckten Anschlußvorrichtung.The contact terminals preferably extend parallel to the Flat cable. This leads to a narrow, elongated Connecting device.

Alternativ dazu können zwei der Kontaktklemmen sich quer zum Flachkabel erstrecken. Dadurch wird die Anschlußvorrichtung kürzer. Bei geschickter Anordnung der Klemmen muß die Breite der Vorrichtung nicht vergrößert werden.Alternatively, two of the contact terminals can be perpendicular to the Extend flat cable. This will make the connector shorter. With a clever arrangement of the clamps, the width must be the device can not be enlarged.

Gemäß einer Ausgestaltung der Erfindung ist der Boden mittels Schnapphaken mit dem Basisteil lösbar verrastet. Dadurch entfällt jede Schiebebewegung des Bodens gegenüber dem Flachkabel.According to one embodiment of the invention, the floor releasably locked to the base part by means of snap hooks. This eliminates any sliding movement across the floor the flat cable.

Alternativ dazu kann der Boden auch mittels Bajonett mit dem Basisteil verbunden werden. Es versteht sich, daß dabei ein Bajonettverschluß verwendet wird, der nur einen sehr kurzen Schiebeweg benötigt.Alternatively, the floor can also be attached to the Base part to be connected. It is understood that a Bayonet lock is used, which is only a very short Sliding path needed.

Schließlich besteht auch noch die Möglichkeit, den Boden in Führungsnuten einzuschieben, die in das Basisteil eingeformt sind.Finally, there is also the option of putting the floor in Insert guide grooves that are molded into the base part are.

Vorteilhafterweise ist der Deckel mit dem Basisteil verrastet. Dabei empfiehlt es sich, wenigstens eine der Rasten so auszubilden, daß sie nur mittels Werkzeug geöffnet werden kann. Dadurch ist das Abnehmen des Deckels nicht bzw. nur erschwert möglich, so daß unbefugte Personen die spannungsführenden Metallteile nicht berühren können.The cover with the base part is advantageous locked. It is recommended that at least one of the Design catches so that they can only be opened using a tool can be. This means that the cover cannot be removed or only possible with difficulty, so that unauthorized persons cannot touch live metal parts.

Vorzugsweise ist am Basisteil nur eine Zugentlastungsbrücke und im Deckel nur eine Kabeldurchführung vorgesehen. Dies genügt, da üblicherweise nur ein Abzweigkabel angeschlossen wird. Gleichzeitig führt es zu einer Verkürzung der Anschlußvorrichtung.Preferably there is only one strain relief bridge on the base part and only one cable entry is provided in the cover. This is sufficient, since usually only one branch cable is connected becomes. At the same time it leads to a shortening of the Connecting device.

Soll von dem Drehstrom-führenden Flachkabel nur Ein-Phasen-Wechselstrom abgegriffen werden, so muß nur einer der drei Phasen-Leiter kontaktiert werden. Es genügt daher auch nur eine Kontaktklemme und nur eine Kontaktschraube, die dann zwischen den entsprechenden Vertiefungen im Basisteil umgesteckt wird. Um diesen Vorgang zu vereinfachen und zu beschleunigen, sind die Öffnungen für die Kontaktschraube als Langloch realisiert, in dem die Kontaktschraube in die gewünschte Position geschoben werden kann.Should only of the three-phase lead flat cable Single-phase alternating current can be tapped, so only one has to of the three phase conductors are contacted. It is therefore sufficient also only one contact terminal and only one contact screw, which then between the corresponding wells in the Base part is repositioned. To simplify this process and to speed up are the openings for that Contact screw realized as an elongated hole in which the Contact screw can be pushed into the desired position can.

Die Fig. 1 bis 3 zeigen als Draufsicht, Längsschnitt bzw. Ansicht eine Anschlußvorrichtung 10 zum Anschließen einer elektrischen Abzweigleitung an ein Flachkabel 1. Das Flachkabel 1 besitzt fünf Leiter 2, wie es für ein Drehstromsystem mit drei Phasen-Leitern L1, L2, L3, Null-Leiter N und Schutzleiter (= Erde) erforderlich ist Die Anschlußvorrichtung 10 besteht aus drei Teilen, einem Basisteil 11, einem lösbaren Boden 12 und einem abnehmbaren Deckel 13. Der Boden 12 ist mittels Schnapphaken 19 (Fig. 3) auf das Basisteil 11 aufgerastet. Dadurch entsteht zwischen Basisteil 11 und Boden 12 ein Aufnahmeraum, in den das auf einer Seite abgeschrägte Flachkabel 1 unverwechselbar eingelegt werden kann.1 to 3 show a plan view, longitudinal section or View of a connection device 10 for connecting a electrical branch line to a flat cable 1. Das Flat cable 1 has five conductors 2, as is the case for one Three-phase system with three phase conductors L1, L2, L3, Neutral conductor N and protective conductor (= earth) is required The connecting device 10 consists of three parts, one Base part 11, a removable base 12 and a removable Lid 13. The bottom 12 is by means of snap hooks 19 (Fig. 3) snapped onto the base part 11. This creates between Base part 11 and floor 12 a receiving space in which the one side beveled flat cable 1 distinctive can be inserted.

In der Unterseite des Basisteils 11 sind zum Flachkabel 1 offene Vertiefungen 16 vorgesehen, in die schraubenlose Anschlußklemmen 24 ... 26 formschlüssig eingesteckt sind. Diese Klemmen sollen anhand der Fig. 4 bis 8 noch im einzelnen erläutert werden.In the bottom of the base part 11 are to the flat cable 1 open recesses 16 provided in the screwless Terminals 24 ... 26 are inserted positively. These terminals are to be based on FIGS. 4 to 8 individual are explained.

An jeder schraubenlosen Klemme 24 ... 26 ist eine Schraubhalterung 22 angebracht, in der eine Kontaktschraube 20 mit Kontaktspitze 21 geführt ist. Die Kontaktschraube 20 sichert die schraubenlose Kontaktklemme 24 ... 26 gegen ein Herausfallen aus der Vertiefung 16.There is one on each screwless terminal 24 ... 26 Screw bracket 22 attached in which a contact screw 20 is guided with contact tip 21. The contact screw 20 secures the screwless contact clamp 24 ... 26 against Falling out of the recess 16.

Zum Kontaktieren der Leiter 2 des Flachkabels 1 wird die Kontaktschraube 20 heruntergedreht. Dabei durchstößt die Kontaktspitze 21 die Isolierung des Flachkabels 1 und dringt in den Leiter 2 ein. Auf diese Weise entsteht eine sichere, dauerhafte und widerstandsarme Kontaktstelle.To contact the conductor 2 of the flat cable 1 Contact screw 20 turned down. The pierces Contact tip 21 the insulation of the flat cable 1 and penetrates in the conductor 2. This creates a safe, permanent and low-resistance contact point.

Wie Fig. 1 erkennen läßt, sind die fünf, den fünf Leitern 2 des Flachkabels 1 entsprechenden Kontaktklemmen 24 ... 26 in zwei Gruppen zu zwei bzw. drei Klemmen zusammengefaßt. Dabei erstrecken sie sich parallel zum Flachkabel 1. Auf dem Basisteil 11 ist eine Zugentlastungsbrücke 18 vorgesehen, unter der eine Abzweigleitung (nicht dargestellt) befestigt werden kann. Der Deckel 13 besitzt an dieser Stelle eine Kabeldurchführungsöffnung 17. As can be seen in FIG. 1, the five, the five conductors 2 of the flat cable 1 corresponding contact terminals 24 ... 26 in two groups combined to form two or three terminals. Here they extend parallel to the flat cable 1. On the Base part 11, a strain relief bridge 18 is provided, under which a branch line (not shown) is attached can be. The lid 13 has one at this point Cable entry opening 17.

Im Bereich der schraubenlosen Klemmen 24 ... 26 sind im Basisteil Öffnungen 14 zum Einstecken der Drahtenden 9 der Abzweigleitung 8 vorgesehen. Daneben befinden sich Öffnungen 15, durch die ein Werkzeug 7, z. B. die Klinge eines Schraubendrehers, eingeführt werden kann, um die schraubenlosen Klemmen zu lösen.In the area of screwless terminals 24 ... 26 are in Base part openings 14 for inserting the wire ends 9 of the Branch line 8 is provided. There are openings next to it 15, through which a tool 7, z. B. the blade of a Screwdriver, can be introduced to the loosen screwless clamps.

Die Fig. 4 bis 8 zeigen in vier verschiedenen Ansichten und in einem Schnitt Einzelheiten der Klemmen. Man erkennt die aus Blech U-förmig gebogene Schraubhalterung 22 mit eingeschnittenem Gewinde 23, in dem die Kontaktschraube 20 geführt ist. Da sich das Gewinde 23 über die gesamte Höhe der Schenkel der Schraubhalterung 22 erstreckt, ergibt sich eine gute Führung. Gleichzeitig wird ein Spreizen der Schenkel der Schraubhalterung 22 vermieden, so daß der Kunststoff des Basisteils 11 keinen Druck erhält. Dadurch wird das gefürchtete Fließen des Kunststoffs verhindert und der formschlüssige Sitz bleibt erhalten.4 to 8 show in four different views and in a section details of the terminals. You can see that made of sheet metal U-shaped screw bracket 22 with incised thread 23 in which the contact screw 20 is led. Since the thread 23 extends over the entire height the leg of the screw bracket 22 extends good leadership. At the same time, the Avoid leg of the screw bracket 22 so that the Plastic of the base part 11 receives no pressure. Thereby the dreaded flow of the plastic is prevented and the form-fitting seat is retained.

An der Schraubhalterung 22 ist einstückig die schraubenlose Klemme 24, 25, 26 angeformt. Die Kontaktkraft wird durch eine Käfigzugfeder 30 bewirkt. Um das abisolierte Ende 9 der Abzweigleitung 8 einführen und gegebenenfalls auch wieder herausziehen zu können, muß mit einem Werkzeug 7, beispielsweise einer Schraubendreherklinge, die Käfigzugfeder 30 geöffnet werden. Dank dieser Konstruktion ist es möglich, Abzweigleitungen 8 mit starren Leitern oder auch mit Litzen zu kontaktieren.On the screw bracket 22 is the screwless one piece Terminal 24, 25, 26 formed. The contact force is through a cage tension spring 30 causes. To the stripped end 9 of the Introduce branch line 8 and, if necessary, again to be able to pull out, must be with a tool 7, for example a screwdriver blade that Cage tension spring 30 can be opened. Thanks to this construction it is possible to use branch lines 8 with rigid conductors or also to be contacted with strands.

Wie die Fig. 1 bis 3 erkennen lassen, sind alle Elemente der Anschlußvorrichtung 10, die der Elektroinstallateur betätigen muß, von der Oberseite aus zugänglich. Dies sind die Kontaktschrauben 20, die Käfigzugfedern 30, und die Kontaktklemmen 22 ... 25. Das bedeutet, daß die Anschlußvorrichtung 10 nicht mehr gedreht und gewendet werden muß, sobald der Boden 12 aufgeschnappt und die Vorrichtung 10 am Flachkabel 1 befestigt ist.As can be seen in FIGS. 1 to 3, all elements of the Connection device 10 that the electrician must operate, accessible from the top. these are the contact screws 20, the cage clamp springs 30, and the Contact terminals 22 ... 25. This means that the Connection device 10 no longer rotated and turned must be as soon as the bottom 12 is snapped and the Device 10 is attached to the flat cable 1.

Der Deckel 13 ist mit Hilfe dreier Rasten 13.1, 13.2 am Basisteil 11 lösbar befestigt. Eine der Rasten 13.1 ist so ausgebildet, daß sie nur mittels Werkzeug geöffnet werden kann. Dadurch ist ein unbefugtes Abnehmen des Deckels 13 ausgeschlossen.The lid 13 is with the help of three notches 13.1, 13.2 Base part 11 releasably attached. One of the catches 13.1 is like this trained that they can only be opened by means of tools can. This makes unauthorized removal of the cover 13 locked out.

Fig. 9 zeigt eine alternative Ausführungsform einer Anschlußvorrichtung als Draufsicht. Da nur Ein-Phasen-Wechselstrom abgegriffen werden soll, muß nur einer der drei Phasen-Leiter L1, L2, L3 kontaktiert werden. Aus diesem Grunde ist eine Kontaktklemme vorgesehen, die je nach Bedarf umgesteckt werden kann. Um dies schnell und bequem realisieren zu können, sind die für die Kontaktschraube 20 vorgesehenen Öffnungen als Langloch 29 ausgebildet. Zum Versetzen der Kontaktklemme wird zunächst die Kontaktschraube 20 so weit gelockert, daß die Kontaktklemme aus ihrer unten offenen Vertiefung freikommt. Anschließend werden Kontaktklemme und Kontaktschraube 20 in die gewünschte Position geschoben. Durch Wiederanziehen der Kontaktschraube 20 wird die Kontaktklemme in der Vertiefung fixiert.9 shows an alternative embodiment of a Connection device as a top view. Because only One-phase alternating current must only be tapped one of the three phase conductors L1, L2, L3 can be contacted. For this reason, a contact terminal is provided, each can be repositioned as required. To do this quickly and To be able to realize them comfortably are for Contact screw 20 provided openings as an elongated hole 29th educated. To move the contact terminal first the contact screw 20 loosened so far that the Contact clamp comes free from its depression open at the bottom. Then the contact clamp and contact screw 20 in pushed the desired position. By tightening the Contact screw 20 becomes the contact clamp in the recess fixed.
