Description

Die vorliegende Erfindung betrifft eine Kabelabzweigklemme zum elektrischen Verbinden eines insbesondere isolierten Hauptleiters mit einem Abzweigleiter.The present invention relates to a cable branch terminal for electrically connecting a main conductor, in particular an insulated one, to a branch conductor.

Um beispielsweise Elektroanlagen einzelner Verbraucher an ein Haupt- oder Stammkabel anzuschließen, welches in der Nähe des Verbrauchers verlegt wird oder bereits verlegt wurde, ist es allgemein bekannt, sogenannte Abzweigmuffen einzubauen. In den Abzweigmuffen wird mindestens ein Leiter des Abzweigkabels über eine Kabelabzweigklemme mit dem entsprechenden Leiter des Stammkabels bzw. des Hauptleiters verbunden. Dazu sind die Isolier- und Schutzschichten der Kabel (Leiterisolierung, Zwickelfüllung und Kabelmantel) teilweise zu entfernen und nach dem Klemmen durch die Isolierung der Muffe wiederherzustellen. Als Klemmen werden dafür Einzelklemmen und so genannte Kompaktabzweigklammen eingesetzt.For example, to connect electrical systems of individual consumers to a main or trunk cable that is being laid near the consumer or has already been laid, it is generally known to install so-called branch sleeves. In the branch joints, at least one conductor of the branch cable is connected to the corresponding conductor of the trunk cable or the main conductor via a cable branch terminal. To do this, the insulating and protective layers of the cable (conductor insulation, gusset filling and cable sheath) must be partially removed and restored after clamping with the insulation of the sleeve. Single terminals and so-called compact branch terminals are used as terminals.

Kabelabzweigklemmen der hier berücksichtigten Art weisen in der Regel eine primärisolationsdurchdringende Kontaktklemme mit mindestens einer in einem Klemmkörper geführten Kontaktschraube und einer zumindest bereichsweise der Stirnseite der Kontaktschraube gegenüberliegenden Vorrichtung zum Schneiden der Primärisolation einer Ader des Hauptleiters auf. Die Vorrichtung zum Schneiden der Primärisolation einer Ader des Hauptleiters weist in der Regel entsprechende Schneidkanten auf, die dazu bestimmt sind, die Isolierung des Hauptleiters zu durchdringen, um eine elektrische Verbindung mit dem elektrischen Leiter des Hauptleiters herzustellen.Cable branch terminals of the type considered here usually have a primary insulation-penetrating contact terminal with at least one contact screw guided in a terminal body and a device for cutting the primary insulation of a core of the main conductor, located at least in regions opposite the end face of the contact screw. The device for cutting the primary insulation of a core of the main conductor usually has corresponding cutting edges intended to pierce the insulation of the main conductor in order to establish an electrical connection with the electrical conductor of the main conductor.

Unter dem hier verwendeten Begriff "Primärisolation" ist die Isolation der einzelnen Adern, insbesondere eines mehradrigen Kabels zu verstehen. Die Primärisolation besteht aus einem elektrisch isolierenden Material, insbesondere Kunststoff und/oder Papier, wobei es jedoch häufig vorkommt, dass sich die für die Primärisolation eingesetzten Kunststoffmaterialien von Kabel zu Kabel im Hinblick auf das Kunststoffmaterial und/oder im Hinblick auf die Stärke (Dicke) der Kunststoffisolation unterscheiden. Gerade in jüngerer Zeit werden zunehmend Kabel eingesetzt, dessen Adern mit nur einer relativ dünnen Primärisolation versehen sind, um so Material einsparen zu können.The term "primary insulation" used here means the insulation of the individual wires, in particular of a multi-wire cable. The primary insulation consists of an electrically insulating material, in particular plastic and/or paper, although it often happens that the plastic materials used for the primary insulation differ from cable to cable with regard to the plastic material and/or with regard to the strength (thickness) of the plastic insulation. Recently, more and more cables have been used whose cores are only provided with a relatively thin primary insulation in order to be able to save material.

Abgesehen von den unterschiedlichen Stärken (Dicken) der als Primärisolation verwendeten Kunststoffisolation weisen die üblicherweise als Primärisolation eingesetzten Kunststoff- und/oder Papiermaterialien unterschiedliche mechanische und thermische Eigenschaften auf, die einen Einfluss auf die für ein Eindringen und Durchdringen der Schneidkanten einer Kabelabzweigklemme notwendige Kraft haben.Apart from the different strengths (thicknesses) of the plastic insulation used as primary insulation, the plastic and/or paper materials commonly used as primary insulation have different mechanical and thermal properties which have an influence on the force necessary to penetrate and pierce the cutting edges of a cable branch terminal.

Die üblicherweise bei Kabelabzweigklemmen zum Einsatz kommenden Schneidkanten zum Schneiden der Primärisolation einer Ader eines Hauptleiters sind in der Regel im Hinblick auf den elektrischen Leiter des Hauptleiters zu "aggressiv" ausgeführt, da die Schneiden beim Kontaktieren des Hauptleiters nicht nur die Primärisolation durchdringen, sondern auch die Gefahr besteht, dass der Innenleiter des Hauptleiters beschädigt bzw. durchdringt wird.The cutting edges that are usually used with cable junction terminals to cut the primary insulation of a core of a main conductor are usually designed too "aggressively" with regard to the electrical conductor of the main conductor, since the cutting edges not only penetrate the primary insulation when contacting the main conductor, but also the There is a risk that the inner conductor of the main conductor will be damaged or penetrated.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, eine Kabelabzweigklemme zum elektrischen Verbinden eines insbesondere isolierten Hauptleiters mit einem Abzweigleiter anzugeben, wobei das Risiko minimiert ist, dass beim galvanischen Kontaktieren des Innenleiters des Hauptleiters dieser geschwächt oder in unangemessener Weise beschädigt wird.The present invention is therefore based on the object of specifying a cable branch terminal for electrically connecting a main conductor, in particular an insulated one, to a branch conductor, with the risk that the inner conductor of the main conductor being galvanically contacted being weakened or damaged in an unreasonable manner is minimized.

Diese Aufgabe wird durch den Gegenstand des unabhängigen Patentanspruchs 1 gelöst, der eine Kabelabzweigklemme betrifft, die ein eine Druckschraube für den Hauptleiter führendes Kopfstück und ein mit dem Kopfstück insbesondere lösbar befestigtes, insbesondere bügelförmiges Widerlager aufweist, gegen welches sich der Hauptleiter abstützt. In dem Kopfstück ist eine insbesondere als Bohrung ausgeführte Aufnahme für den Abzweigleiter ausgeführt.This object is achieved by the subject matter of independent patent claim 1, which relates to a cable branch terminal which has a head piece guiding a pressure screw for the main conductor and a particularly bow-shaped abutment which is particularly releasably fastened to the head piece and against which the main conductor is supported. A receptacle for the branch conductor, which is designed in particular as a bore, is designed in the headpiece.

Die erfindungsgemäße Kabelabzweigklemme zeichnet sich insbesondere dadurch aus, dass das insbesondere bügelförmige Widerlager zumindest in einem dem Kopfstück gegenüberliegenden Bereich mindestens eine und vorzugsweise eine Vielzahl von insbesondere pyramidenförmigen Schneidzähne aufweist.The cable branch terminal according to the invention is characterized in particular by the fact that the abutment, which is in particular bow-shaped, has at least one and preferably a large number of, in particular, pyramid-shaped cutting teeth, at least in a region opposite the head piece.

Durch die Verwendung von einzelnen Schneidzähnen, die insbesondere zumindest im Wesentlichen pyramidenförmig ausgeführt sind, ist einerseits eine zuverlässige galvanische Kontaktierung des Innenleiters des Hauptleiters möglich, und zwar selbst bei unterschiedlichen Ausgestaltungen der Primärisolation des Hauptleiters, ohne dass jedoch die Gefahr besteht, dass beim galvanischen Kontaktieren des Innenleiters des Hauptleiters dieser geschwächt oder gar selbst durchdrungen wird.The use of individual cutting teeth, which are in particular at least essentially pyramid-shaped, enables reliable galvanic contacting of the inner conductor of the main conductor, even with different configurations of the primary insulation of the main conductor, but without the risk of galvanic contacting of the inner conductor of the main conductor this is weakened or even penetrated.

Gemäß einem weiteren Aspekt betrifft die Erfindung eine Kabelabzweigklemme zum elektrischen Verbinden eines insbesondere isolierten Hauptleiters mit einem Abzweigleiter, wobei die Kabelabzweigklemme ein eine Druckschraube für den Hauptleiter führendes Kopfstück und ein mit dem Kopfstück insbesondere lösbar befestigtes, insbesondere bügelförmiges Widerlager aufweist, gegen welches sich der Hauptleiter abstützt, wobei in dem Kopfstück eine insbesondere als Bohrung ausgeführte Aufnahme für den Abzweigleiter ausgeführt ist.According to a further aspect, the invention relates to a cable branch terminal for electrically connecting a main conductor, in particular an insulated one, to a branch conductor, the cable branch terminal having a head piece that guides a pressure screw for the main conductor and a particularly bow-shaped abutment which is particularly releasably fastened to the head piece and against which the main conductor rests is supported, wherein in the head piece is designed in particular as a bore receptacle for the branch conductor.

Die Kabelabzweigklemme gemäß dem zweiten Aspekt der Erfindung zeichnet sich insbesondere dadurch aus, dass die Druckschraube als Frässchraube ausgebildet ist und einen dem Hauptleiter zugewandten kugelkalottenförmigen Endbereich aufweist, wobei in dem kugelkalottenförmigen Endbereich der Druckschraube eine insbesondere kreisförmige Ausnehmung ausgebildet ist.The cable junction terminal according to the second aspect of the invention is characterized in particular by the fact that the pressure screw is designed as a milled screw and has a spherical segment-shaped end area facing the main conductor, with a particularly circular recess being formed in the spherical segment-shaped end area of the pressure screw.

Vorzugsweise ist die insbesondere kreisförmige Ausnehmung mit Bezug zur Längsachse der Druckschraube konzentrisch ausgeführt.Preferably, the in particular circular recess is concentric with respect to the longitudinal axis of the pressure screw.

Die insbesondere kreisförmige Ausnehmung ist vorzugsweise als ein in dem kugelkalottenförmigen Endbereich der Druckschraube ausgeführtes Sackloch ausgebildet und definiert umfangsmäßig zumindest bereichsweise eine Schneidkante zum Durchdringen einer Isolation des Hauptleiters. Dabei bildet das Sackloch ein Reservoir zur Aufnahme der mit der Schneidkante separierten Isolation des Hauptleiters aus.The in particular circular recess is preferably designed as a blind hole in the spherical segment-shaped end area of the pressure screw and circumferentially defines, at least in certain areas, a cutting edge for penetrating an insulation of the main conductor. The blind hole forms a reservoir for receiving the insulation of the main conductor separated by the cutting edge.

Mit anderen Worten, das in dem kugelkalottenförmigen Endbereich der Druckschraube ausgeführte Sackloch nimmt beim Kontaktieren des Innenleiters des Hauptleiters zumindest einen Teil der mit Hilfe der als Frässchraube ausgeführten Druckschraube ausgestanzten Primärisolation des Hauptleiters auf. Der kugelkalottenförmige Endbereich der Druckschraube dient insbesondere dazu, das Isolationsmaterial des Hauptleiters, welches nicht von dem als Reservoir dienenden Sackloch aufgenommen ist, radial nach außen zu verdrängen.In other words, when contacting the inner conductor of the main conductor, the blind hole in the spherical cap-shaped end area of the pressure screw accommodates at least part of the primary insulation of the main conductor that was punched out with the aid of the pressure screw designed as a milling screw. The spherical segment-shaped end area of the pressure screw serves in particular to displace the insulation material of the main conductor, which is not accommodated by the blind hole serving as a reservoir, radially outwards.

Daher bietet die Kabelabzweigklemme gemäß dem zweiten Aspekt der Erfindung eine leicht zu realisierende aber dennoch effektive Weise, reproduzierbar einen Hauptleiter galvanisch an der Kabelabzweigklemme anzuschließen.Therefore, according to the second aspect of the invention, the cable branch terminal offers an easy-to-implement but nevertheless effective way of galvanically connecting a main conductor to the cable branch terminal in a reproducible manner.

Wie bereits ausgeführt, weist das insbesondere bügelförmige Widerlager der Kabelabzweigklemme in einem dem Kopfstück gegenüberliegenden Bereich mindestens eine und vorzugsweise eine Vielzahl von insbesondere pyramidenförmigen Schneidzähne auf. Diese Schneidzähne sind insbesondere auf einem Metallband angeordnet, welches in einen von dem insbesondere bügelförmigen Widerlager ausgebildeten Bügelbereich insbesondere austauschbar eingelegt ist.As already stated, the abutment of the cable branch terminal, which is in particular in the form of a bow, has at least one and preferably a large number of, in particular, pyramid-shaped cutting teeth in a region opposite the head piece. These cutting teeth are in particular arranged on a metal band which is inserted in particular interchangeably into a bracket area formed by the bracket-shaped abutment in particular.

Diese Ausgestaltung ermöglicht es, die Schneidzähne des insbesondere bügelförmigen Widerlagers in einer möglichst effizienten Weise an unterschiedlich ausgeführte Primärisolationen des Hauptleiters anzupassen, um die Primärisolation wirksam durchdringen und die Ader bzw. den Innenleiter des Hauptleiters galvanisch kontaktieren zu können.This configuration enables the cutting teeth of the particularly bow-shaped abutment to be adapted as efficiently as possible to differently designed primary insulation of the main conductor in order to be able to effectively penetrate the primary insulation and galvanically contact the wire or the inner conductor of the main conductor.

Gemäß Ausführungsformen der erfindungsgemäßen Kabelabzweigklemme weist das insbesondere bügelförmige Widerlager einen im Querschnitt zumindest im Wesentlichen U-förmigen Bügel auf, zwischen dessen Schenkeln der Hauptleiter eingelegt oder einlegbar ist, wobei das Kopfstück der Kabelabzweigklemme mindestens eine Nut aufweist, in welche eine hakenförmige Gratleiste des Widerlagers eingreift.According to embodiments of the cable branch terminal according to the invention, the in particular bracket-shaped abutment has a bracket that is at least essentially U-shaped in cross section, between the legs of which the main conductor is or can be inserted, the head piece of the cable branch terminal having at least one groove into which a hook-shaped ridge strip of the abutment engages .

Mit anderen Worten, bevorzugt ist die Kabelabzweigklemme zweiteilig ausgeführt, wobei der Hauptleiter zwischen den Schenkeln des U-förmigen Bügels eingelegt werden kann, und wobei anschließend das Kopfstück der Kabelabzweigklemme lösbar mit dem U-förmigen Bügel des bügelförmigen Widerlagers verbunden wird.In other words, the branching cable clamp is preferably made in two parts, with the main conductor being able to be inserted between the legs of the U-shaped bracket, and the head piece of the branching cable clamp then being detachably connected to the U-shaped bracket of the bracket-shaped abutment.

Gemäß einem weiteren (dritten) Aspekt betrifft die Erfindung eine Kabelabzweigklemme, welche ein eine Druckschraube für einen Hauptleiter führendes Kopfstück und ein mit dem Kopfstück insbesondere lösbar befestigtes, insbesondere bügelförmiges Widerlager aufweist, gegen welches sich der Hauptleiter abstützt.According to a further (third) aspect, the invention relates to a cable junction terminal which has a head piece guiding a pressure screw for a main conductor and a particularly bow-shaped abutment which is particularly releasably fastened to the head piece and against which the main conductor is supported.

Die Kabelabzweigklemme gemäß dem dritten Aspekt der vorliegenden Erfindung zeichnet sich insbesondere dadurch aus, dass zum Ansatz eines Werkzeugs, insbesondere eines Schraubendrehers oder eines Schraubenschlüssels, der Druckschraube ein Druckschraubenantrieb zugeordnet ist, welcher mit einem Schaftbereich der Druckschraube an einem dem Hauptleiter abgewandten Endbereich der Druckschraube verbunden ist.The cable junction terminal according to the third aspect of the present invention is characterized in particular by the fact that a pressure screw drive is assigned to the pressure screw for the application of a tool, in particular a screwdriver or a wrench, which is connected to a shank area of the pressure screw at an end area of the pressure screw facing away from the main conductor is.

Der Druckschraubenantrieb ist insbesondere als ein vorzugsweise aus einem Kunststoffmaterial gebildetes und mit dem Schaftbereich der Druckschraube vorzugsweise über eine kraft- und/oder formschlüssige Verbindung, insbesondere über eine Steckverbindung, verbindbares Bauteil ausgeführt.The pressure screw drive is designed in particular as a component which is preferably formed from a plastic material and can be connected to the shank region of the pressure screw preferably via a non-positive and/or positive connection, in particular via a plug-in connection.

Indem der Druckschraubenantrieb der Kabelabzweigklemme vorzugsweise aus einem Kunststoffmaterial gebildet ist, ist die Kabelabzweigklemme insbesondere leichter ausgestaltbar im Vergleich zu herkömmlichen Kabelabzweigklemmen, bei denen der Druckschraubenantrieb selber aus dem gleichen Material gebildet ist, wie dem Material der Druckschraube.Because the pressure screw drive of the branch cable clamp is preferably made of a plastic material, the branch cable clamp can be made lighter in comparison to conventional branch cable clamps in which the pressure screw drive itself is made of the same material as the material of the pressure screw.

Gemäß Ausgestaltungen insbesondere der zuletzt genannten Ausführungsvariante der erfindungsgemäßen Kabelabzweigklemme ist vorgesehen, dass in einem Körper des Druckschraubenantriebs eine Sollbruchstelle, insbesondere in Gestalt einer Materialverjüngung beispielsweise in Form einer Kerbe, Perforation oder Ritzspur, ausgebildet ist, welche ausgeführt ist, bei einem vorab festgelegten oder festlegbaren und von dem Druckschraubenantrieb auf den Schaftbereich der Druckschraube ausgeübten Drehmoment derart anzusprechen, dass eine Wirkverbindung zwischen dem Druckschraubenantrieb und der Druckschraube getrennt wird.According to configurations, in particular of the last-mentioned embodiment variant of the cable branch clamp according to the invention, it is provided that a predetermined breaking point, in particular in the form of a material reduction, for example in the form of a notch, perforation or scratch, is formed in a body of the pressure screw drive, which is carried out at a predetermined or determinable point and responsive to torque exerted by the jackscrew driver on the shank portion of the jackscrew such that an operative connection between the jackscrew driver and the jackscrew is broken.

Diese Ausgestaltung liefert den entscheidenden Vorteil, dass beim Ansprechen der Sollbruchstelle des Druckschraubenantriebs eine saubere Bruchstelle erzielbar ist, was Vorteile mit sich bringt, wenn anschließend die Kabelabzweigklemme in einer entsprechenden Kabelabzweigmuffe einzubauen ist.This configuration provides the decisive advantage that when the predetermined breaking point of the pressure screw drive responds, a clean breaking point can be achieved, which has advantages if the cable branch clamp is then to be installed in a corresponding cable branch sleeve.

Nachfolgend wird unter Bezugnahme auf die beiliegenden Zeichnungen eine bevorzugte Ausführungsform der Erfindung näher beschrieben.A preferred embodiment of the invention is described in more detail below with reference to the accompanying drawings.

Die in FIG. 1 und FIG. 2 dargestellte Kabelabzweigklemme 1 besteht aus einem aus beispielsweise Messing hergestellten Kopfstück 6, welches eine Druckschraube 2 für den galvanisch zu kontaktierenden Hauptleiter 100 führt. Darüber hinaus weist die Kabelabzweigklemme 1 ein mit dem Kopfstück 6 insbesondere lösbar befestigtes, insbesondere bügelförmiges Widerlager 7 auf, gegen welches sich der Hauptleiter 100 abstützt.In the FIG. 1 and FIG. 2 The cable branch terminal 1 shown consists of a head piece 6 made of brass, for example, which carries a pressure screw 2 for the main conductor 100 to be electrically contacted. In addition, the cable branch terminal 1 has an abutment 7, which is in particular detachably fastened to the head piece 6 and is in particular bow-shaped, against which the main conductor 100 is supported.

Das insbesondere bügelförmige Widerlager 7 weist einen im Querschnitt zumindest im Wesentlichen U-förmigen Bügel auf, zwischen dessen Schenkeln der Hauptleiter 100 eingelegt oder einlegbar ist.The in particular bracket-shaped abutment 7 has a bracket that is at least essentially U-shaped in cross section, between the legs of which the main conductor 100 is or can be inserted.

Insbesondere ist das Kopfstück 6 mit dem bügelförmigen Widerlager 7 lösbar verbunden. Hierzu weist bei der in den Zeichnungen dargestellten Ausführungsform das Kopfstück 6 entsprechende Nuten 9 auf, in welche jeweils eine hakenförmige Gratleiste 10 des Widerlagers 7 eingreift.In particular, the head piece 6 is detachably connected to the bow-shaped abutment 7 . For this purpose, in the embodiment shown in the drawings, the head piece 6 has corresponding grooves 9, in each of which a hook-shaped ridge strip 10 of the abutment 7 engages.

In dem Kopfstück 6 der Kabelabzweigklemme 1 ist ferner eine insbesondere als Bohrung ausgeführte Aufnahme 14 für einen Abzweigleiter ausgeführt.In the head piece 6 of the cable branch terminal 1 there is also a receptacle 14, designed in particular as a bore, for a branch conductor.

Die erfindungsgemäße Kabelabzweigklemme 1, wie sie anhand einer exemplarischen Ausführungsform in den beiliegenden Zeichnungen gezeigt ist, zeichnet sich insbesondere dadurch aus, dass das insbesondere bügelförmige Widerlager 7 zumindest in einem dem Kopfstück 6 gegenüberliegenden Bereich insbesondere pyramidenförmige Schneidzähne 8 aufweist, mit Hilfe welcher wirkungsvoll die Primärisolation des Hauptleiters 100 durchdrungen werden kann.The cable branch terminal 1 according to the invention, as shown in an exemplary embodiment in the accompanying drawings, is characterized in particular by the fact that the particular bracket-shaped abutment 7 at least in a headpiece 6 opposite area in particular has pyramid-shaped cutting teeth 8, with the aid of which the primary insulation of the main conductor 100 can be effectively penetrated.

In diesem Zusammenhang bietet es sich an, dass die pyramidenförmigen Schneidzähne 8 auf einem Metallband angeordnet sind, welches in einen von dem insbesondere bügelförmigen Widerlager 7 ausgebildeten Bügelbereich vorzugsweise austauschbar eingelegt ist.In this context, it makes sense for the pyramid-shaped cutting teeth 8 to be arranged on a metal band, which is preferably interchangeably inserted into a bracket area formed by the bracket-shaped abutment 7 in particular.

Die in den Zeichnungen gezeigte exemplarische Ausführungsform der erfindungsgemäßen Kabelabzweigklemme 1 zeichnet sich insbesondere ferner dadurch aus, dass die von dem Kopfstück 6 der Kabelabzweigklemme 1 geführte Druckschraube 2 als Frässchraube ausgebildet ist und einen dem Hauptleiter 100 zugewandten kugelkalottenförmigen Endbereich 3 aufweist, wobei in dem kugelkalottenförmigen Endbereich 3 der Druckschraube 2 eine insbesondere kreisförmige Ausnehmung 4 ausgebildet ist.The exemplary embodiment of the cable branch terminal 1 according to the invention shown in the drawings is also characterized in particular by the fact that the pressure screw 2 guided by the head piece 6 of the cable branch terminal 1 is designed as a milled screw and has a spherical segment-shaped end area 3 facing the main conductor 100, wherein in the spherical segment-shaped end area 3 of the pressure screw 2, in particular a circular recess 4 is formed.

Die insbesondere kreisförmige Ausnehmung 4 in dem kugelkalottenförmigen Endbereich 3 der Druckschraube 2 ist vorzugsweise mit Bezug zur Längsachse der Druckschraube 2 konzentrisch ausgebildet.The in particular circular recess 4 in the spherical segment-shaped end region 3 of the pressure screw 2 is preferably formed concentrically with respect to the longitudinal axis of the pressure screw 2 .

Die insbesondere kreisförmige Ausnehmung 4 in dem kugelkalottenförmigen Endbereich 3 der Druckschraube 2 ist bei der in den Zeichnungen gezeigten Ausführungsform als ein in dem kugelkalottenförmigen Endbereich 3 der Druckschraube 2 ausgeführtes Sackloch 5 ausgebildet und definiert umfangsmäßig zumindest bereichsweise eine Schneidkante zum Durchdringen einer Isolation des Hauptleiters 100. Das Sackloch 5 selber bildet dabei ein Reservoir zur Aufnahme der mit der Schneidkante separierten Isolation des Hauptleiters 100 aus.In the embodiment shown in the drawings, the in particular circular recess 4 in the spherical cap-shaped end region 3 of the pressure screw 2 is designed as a blind hole 5 in the spherical cap-shaped end region 3 of the pressure screw 2 and circumferentially defines at least regions of a cutting edge for penetrating an insulation of the main conductor 100. The blind hole 5 itself forms a reservoir for receiving the insulation of the main conductor 100 separated by the cutting edge.

Zum Ansatz eines Werkzeugs, insbesondere eines Schraubendrehers oder eines Schraubenschlüssels, ist der Druckschraube 2 ein Druckschraubenantrieb 11 zugeordnet, welcher mit einem Schaftbereich 13 der Druckschraube 2 an einem dem Hauptleiter 100 abgewandten Endbereich 3 der Druckschraube 2 verbunden ist.A pressure screw drive 11 is assigned to the pressure screw 2 for the application of a tool, in particular a screwdriver or a spanner.

Der Druckschraubenantrieb 11 ist dabei als ein insbesondere aus einem Kunststoffmaterial gebildetes und mit dem Schaftbereich 13 der Druckschraube 2 vorzugsweise über eine kraft- und/oder formschlüssige Verbindung, insbesondere über eine Steckverbindung, verbindbares Bauteil ausgeführt.The pressure screw drive 11 is designed as a component made in particular from a plastic material and connectable to the shank region 13 of the pressure screw 2 preferably via a non-positive and/or positive connection, in particular via a plug-in connection.

In einem Körper des Druckschraubenantriebs 11 ist eine Sollbruchstelle 12, insbesondere in Gestalt einer Materialverjüngung beispielsweise in Form einer Kerbe, Perforation oder Ritzspur, ausgebildet, welche ausgeführt ist, bei einem vorab festgelegten oder festlegbaren und von dem Druckschraubenantrieb 11 auf den Schaftbereich 13 der Druckschraube 2 ausgeübten Drehmoment derart anzusprechen, dass eine Wirkverbindung zwischen dem Druckschraubenantrieb 11 und der Druckschraube 2 getrennt wird.In a body of the pressure screw drive 11, there is a predetermined breaking point 12, in particular in the form of a tapered material, for example in the form of a notch, perforation or scratch mark, which is implemented at a predetermined or fixable point and of the pressure screw drive 11 on the shank region 13 of the pressure screw 2 to address the torque exerted in such a way that an operative connection between the pressure screw drive 11 and the pressure screw 2 is separated.
