Derartige Vorrichtungen werden auch als Klemmringe bezeichnet. Diese Such devices are also referred to as clamping rings. These
Bezeichnung wird im folgenden anstelle des Wortes„Vorrichtung" verwendet. Die Klemmringe dienen insbesondere zur elektrisch leitenden Verbindung der Leiter eines beispielsweise im Bürgersteigbereich verlegten, der Stromversorgung dienenden Starkstromkabels mit Abzweigkabeln, die zu Häusern oder anderen Einheiten geführt werden. Die Klemmringe sollen dabei so ausgeführt sein, daß das Starkstromkabel bzw. dessen Leiter nicht aufgetrennt zu werden brauchen. Designation is used in the following instead of the word "device."

Ein in diesem Sinne geeigneter Klemmring geht aus der eingangs erwähnten EP 1 553 662 Bl hervor. Er besteht aus einem vierteiligen Klemmrahmen, welcher einen Aufnahmeraum für vier isolierte Hauptleiter eines Starkstromkabels umschließt. In jedem Teil des Klemmrahmens sind ein Kontaktelement mit selbstschneidenden Kontakten und ein Freiraum zum Einstecken eines isolierten Abzweigleiters A suitable in this sense clamping ring is apparent from the aforementioned EP 1 553 662 Bl. It consists of a four-part clamping frame, which encloses a receiving space for four insulated main conductors of a power cable. In each part of the clamping frame are a contact element with self-tapping contacts and a space for inserting an insulated branch conductor
angebracht. Je zwei Teile des Klemmrahmens sind über eine Schraubverbindung miteinander verbunden. Bei festgezogener Schraubverbindung dringen die appropriate. Two parts of the clamping frame are connected to each other via a screw connection. When tightened screw penetrate the
Kontaktelemente mit Durchtritt durch deren Isolierungen in jeweils einen Hauptleiter und den zugehörigen Abzweigleiter ein. Dieser Klemmring hat sich in der Praxis bewährt. Er besteht aber aus relativ vielen Einzelteilen, die zusammengefügt und beim Einsatz des Klemmrings gehandhabt werden müssen. Contact elements with passage through their insulation in each case a main conductor and the associated branch conductor. This clamping ring has become in practice proven. But it consists of relatively many items that need to be put together and handled when using the clamping ring.
Der Erfindung liegt die Aufgabe zugrunde, den eingangs geschilderten Klemmring in Aufbau und Handhabung zu vereinfachen. The invention has for its object to simplify the above-described clamping ring in structure and handling.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, This object is achieved according to the invention characterized
- daß der Klemmrahmen aus zwei zusammenfügbaren und in Montageposition aneinander liegenden Halbschalen besteht, in denen als Führungen für die Kontaktelemente nach außen und in Richtung des Aufnahmeraums offene Teilräume angebracht sind, die auch zum Einlegen je eines Abzweigleiters dienen,  - That the clamping frame consists of two joinable and in the assembled position contiguous half-shells in which open as partitions are mounted as guides for the contact elements to the outside and in the direction of the receiving space, which also serve for inserting a branch conductor,
- daß jedem Teilraum ein aus Isoliermaterial bestehendes Druckstück zugeordnet ist, das in mindestens einer radial verlaufenden Führungsrille beweglich an einer der Halbschalen gelagert und in Montageposition außerhalb des jeweiligen Abzweigleiters positioniert ist, und  - That each subspace is assigned a consisting of insulating material pressure piece, which is mounted in at least one radially extending guide groove movable on one of the half shells and positioned in the mounting position outside the respective branch conductor, and

Abzweigleitern und Kontaktelementen derart radial nach innen verschoben sind, daß die Kontaktelemente jeweils elektrisch leitend mit einem Hauptleiter und einem zugeordneten Abzweigleiter verbunden sind.  Branch conductors and contact elements are displaced radially inwardly such that the contact elements are each electrically connected to a main conductor and an associated branch conductor.
Diese Vorrichtung besteht im wesentlichen aus nur drei Teilen, die am Montageort zusammenzufügen sind. Das sind die beiden mit Kontaktelementen und This device consists essentially of only three parts, which are to be joined together at the installation site. These are the two with contact elements and
Druckstücken ausgerüsteten Halbschalen und das Spannelement. Die nach außen offenen Teilräume, in denen die Kontaktelemente verstellbar angebracht sind, gestatten ein einfaches Einlegen der Abzweigleiter von außen. Nach dem Einlegen der Abzweigleiter wird jeweils ein Druckstück über denselben angeordnet. Das ist dann besonders einfach, wenn die Druckstücke mit Vorteil gelenkig an der jeweiligen Halbschale angeordnet sind. Nach Einlegen der Abzweigleiter in die Teilräume und Positionierung der Druckstücke über denselben braucht nur noch das Spannelement um die beiden Halbschalen herumgelegt und festgezogen zu werden. Die in den Halbschalen geführten Druckstücke werden dabei radial so weit nach innen bewegt, bis die Kontaktelemente jeweils elektrisch leitenden Kontakt mit einem Hauptleiter und einem zugeordneten Abzweigleiter haben. Pressure pieces equipped half shells and the clamping element. The outwardly open subspaces, in which the contact elements are adjustably mounted, allow easy insertion of the branch conductors from the outside. After inserting the branch conductor, a pressure piece is arranged in each case via the same. This is particularly easy when the plungers are arranged with advantage hinged to the respective half-shell. After inserting the branch conductor in the subspaces and positioning the plungers on the same need only be placed around the clamping elements to the two shells and tightened.

Im folgenden wird statt des Wortes„Vorrichtung" weiter das Wort„Klemmring" verwendet. Der Klemmring wird für den Einsatz an einem Starkstromkabel mit vier isolierten Hauptleitern sowie vier anzuschließenden isolierten Abzweigleitern beschrieben. Er könnte auch bei einem Starkstromkabel mit nur drei Hauptleitern verwendet werden. Der vierte Platz könnte dann mit einem sogenannten„Dummy" ausgefüllt sein und es könnte auch ein Nulleiter mit geringeren Abmessungen und entsprechende Auffüllung angebracht werden. Grundsätzlich braucht auch nur ein Abzweigleiter mit einem der Hauptleiter verbunden zu werden. In the following, the word "clamp" will be used instead of the word "device". The clamping ring is described for use on a power cable with four insulated main conductors and four insulated branch conductors to be connected. It could also be used on a power cable with only three main conductors. The fourth place could then be filled with a so-called "dummy" and it could also be a neutral conductor with smaller dimensions and appropriate filling be installed. Basically, only one branch conductor needs to be connected to one of the main conductors.
In Fig. 1 sind zwei aneinander liegende Halbschalen 1 und 2 dargestellt, die aus einem mechanisch stabilen Isoliermaterial bestehen. Sie können identisch ausgeführt und in Montageposition durch einrastende Elemente miteinander verbunden sein. Die beiden Halbschalen schließen einen Aufnahmeraum 3 zwischen sich ein, in dem vier isolierte Hauptleiter 4,5,6 und 7 nahezu unverrückbar angeordnet sind. Für diese unverrückbare Positionierung der Hauptleiter 4 bis 7 können aus den Fig. 2 und 3 ersichtliche, an den Halbschalen 1 und 2 angeformte Stifte 8 und 9 einerseits sowie ein zwischen den Halbschalen 1 und 2 festgelegter Keil 10 aus stabilem Kunststoff andererseits verwendet werden. Die Stifte 8 und 9 sowie der Keil 10 fixieren die Positionen der vier Hauptleiter 4 bis 7 im Aufnahmeraum 3. Sie lassen aber beim Kontaktieren der Hauptleiter 4 bis 7, so wie es weiter unten beschrieben wird, eine durch die Isolierung derselben bedingte, relativ geringfügige Bewegung der In Fig. 1, two adjacent half-shells 1 and 2 are shown, which consist of a mechanically stable insulating material. They can be identically designed and connected together in the assembly position by latching elements. The two half-shells include a receiving space 3 between them, in which four insulated main conductors 4,5,6 and 7 are arranged almost immovable. For this immovable positioning of the main conductors 4 to 7 can be seen from Figs. 2 and 3, integrally formed on the half-shells 1 and 2 pins 8 and 9 on the one hand and between the half-shells 1 and 2 fixed wedge 10 made of plastic on the other. The pins 8 and 9 and the wedge 10 fix the Positions of the four main conductors 4 to 7 in the receiving space 3. However, they leave when contacting the main conductors 4 to 7, as will be described below, due to the isolation thereof, relatively slight movement of the
Hauptleiter 4 bis 7 zu. Das ist in Fig. 3 angedeutet. Main conductors 4 to 7 too. This is indicated in Fig. 3.
In jeder der beiden Halbschalen 1 und 2 sind zwei nach innen und außen offene Teilräume 1 1 angeordnet, in denen jeweils ein Kontaktelement 12 und ein isolierter Abzweigleiter 13 in radialer Richtung - bezogen auf den Mittelpunkt des Klemmrings - verschiebbar angebracht sind. Die Kontaktelemente 12 sind in den Halbschalen 1 und 2 geführt und unverlierbar an denselben angebracht. Sie sind mit Vorteil als selbstschneidende Kontakte ausgeführt. Sie haben dazu beispielsweise auf zwei einander gegenüberliegenden Seiten eine Vielzahl von nach außen abstehenden Zähnen. In each of the two half-shells 1 and 2, two inwardly and outwardly open part spaces 1 1 are arranged, in each of which a contact element 12 and an insulated branch conductor 13 in the radial direction - relative to the center of the clamping ring - are slidably mounted. The contact elements 12 are guided in the half-shells 1 and 2 and mounted captive on the same. They are advantageously designed as self-tapping contacts. They have, for example, on two opposite sides of a plurality of outwardly projecting teeth.
Im Bereich der Teilräume 1 1 ist für jeden Teilraum ein aus Isoliermaterial bestehendes Druckstück 14 vorgesehen, das beweglich aber unverlierbar an der jeweiligen Halbschale 1 oder 2 angebracht und mit Vorteil an Drehpunkten gelenkig an derselben gelagert ist. Für jedes Druckstück 14 ist außerdem mindestens eine in radialer Richtung - bezogen auf den Mittelpunkt des Klemmrings - verlaufende Führungsrille 15 in der jeweiligen Halbschale 1 oder 2 angebracht. Um die beiden Halbschalen 1 und 2 ist ein Spannelement 1 6 herumgelegt, bei dem es sich beispielsweise um eine Schlauchschelle handelt. Das Spannelement 16 kann mittels einer Schraube 1 7 gespannt werden, wodurch es seinen Durchmesser verkleinert und sich enger an die Druckstücke 14 anlegt. In the area of the subspaces 11, a pressure piece 14 consisting of insulating material is provided for each subspace, which is movably but captively attached to the respective half shell 1 or 2 and is pivotally mounted on the same with advantage at pivot points. For each pressure piece 14 is also at least one in the radial direction - relative to the center of the clamping ring - extending guide groove 15 in the respective half-shell 1 or 2 attached. To the two half-shells 1 and 2, a clamping element 1 6 is placed around, which is, for example, a hose clamp. The tensioning element 16 can be tensioned by means of a screw 1 7, whereby it reduces its diameter and engages more closely to the pressure pieces 14.
Der Klemmring nach der Erfindung wird beispielsweise wie folgt gehandhabt: The clamping ring according to the invention is handled, for example, as follows:
An einer Stelle im Verlauf eines Starkstromkabels, an der mindestens ein Abzweigleiter 13 angeschlossen werden soll, wird der Mantel des Starkstromkabels zur Freilegung der vier Hauptleiter 4 bis 7 auf einer ausreichend großen Länge entfernt. Danach wird der Keil 10 zwischen die Hauptleiter 4 bis 7 geschoben, auf dessen einer Seite dann die Hauptleiter 4 und 7 liegen, während es auf der anderen Seite die At one point in the course of a power cable to which at least one branch conductor 13 is to be connected, the jacket of the power cable is removed to expose the four main conductors 4 to 7 on a sufficiently large length. Thereafter, the wedge 10 is pushed between the main conductors 4 to 7, on one side then the main conductors 4 and 7 are, while on the other side of the
Hauptleiter 5 und 6 sind. Danach werden die beiden Halbschalen 1 und 2 von zwei einander gegenüber liegenden Seiten auf die vier Hauptleiter 4 bis 7 aufgesetzt. Dabei dringen die Stifte 8 und 9 zwischen die Hauptleiter 4 und 7 einerseits sowie 5 und 6 andererseits. In ihrer aus den Zeichnungen hervorgehenden Endposition sind die beiden Halbschalen 1 und 2 miteinander durch einrastende Elemente verriegelt. Die Hauptleiter 4 bis 7 sind in dem umschlossenen Aufnahmeraum 3 nahezu unverrückbar festgelegt. Die Kontaktelemente 12 sind - wie bereits erwähnt - während der Montage der beiden Halbschalen 1 und 2 bereits in den Führungen 1 1 angebracht. Main conductors 5 and 6 are. Thereafter, the two half shells 1 and 2 of two opposite sides are placed on the four main conductors 4 to 7. In this case, the pins 8 and 9 penetrate between the main conductors 4 and 7 on the one hand and the fifth and 6 on the other hand. In their resulting from the drawings end position, the two half-shells 1 and 2 are locked together by latching elements. The main conductors 4 to 7 are set in the enclosed receiving space 3 almost immovable. The contact elements 12 are - as already mentioned - during assembly of the two half-shells 1 and 2 already mounted in the guides 1 1.
Anschließend werden die Abzweigleiter 13 in die Führungen 1 1 eingelegt und die Druckstücke 14 werden um ihren jeweiligen Drehpunkt geklappt, so daß sie entsprechend der Darstellung in Fig. 2 außen über den Abzweigleitern 13 liegen und die Teilräume 1 1 verschließen. Abschließend wird das Spannelement 16 um die Druckstücke 14 herumgelegt und mittels der Schraube 1 7 gespannt. Es verkleinert dadurch seinen Durchmesser und bewegt die Druckstücke 14 radial nach innen. Die Druckstücke 14 drücken dabei auf die Abzweigleiter 13 und die Kontaktelemente 12, welche in der Endposition bzw. Montageposition unter Durchdringung der jeweiligen Isolierungen einerseits in einen der Hauptleiter 4 bis 7 und andererseits in einen Abzweigleiter 13 eindringen. Dabei werden entsprechend der Darstellung in Fig. 3 die Stifte 8 und 9 sowie der Keil 10 in die Isolierungen der Hauptleiter 4 bis 7 eingedrückt, so daß deren Material keinen Einfluß auf die Kontaktkraft zwischen den Hauptleitern 4 bis 7 und den Kontaktelementen 12 haben. In Montageposition ist je einer der Hauptleiter 4 bis 7 mit einem der Abzweigleiter 13 elektrisch leitend verbunden. Subsequently, the branch conductors 13 are inserted into the guides 1 1 and the plungers 14 are folded about their respective fulcrum, so that they lie outside the branch conductors 13 as shown in FIG. 2 outside and close the subspaces 1 1. Finally, the clamping element 16 is placed around the pressure pieces 14 and tensioned by means of the screw 1 7. It thereby reduces its diameter and moves the plungers 14 radially inwardly. The pressure pieces 14 press on the branch conductor 13 and the contact elements 12, which penetrate in the end position or mounting position by penetrating the respective insulation on the one hand in one of the main conductors 4 to 7 and on the other hand in a branch conductor 13. In this case, as shown in Fig. 3, the pins 8 and 9 and the wedge 10 are pressed into the insulation of the main conductors 4 to 7, so that their material has no influence on the contact force between the main conductors 4 to 7 and the contact elements 12. In the mounting position, one of the main conductors 4 to 7 is electrically conductively connected to one of the branch conductors 13.
