Description

Die Erfindung betrifft einen Stecker zum Anschließen eines elektrofluidischen Wandlers der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a plug for connecting an electrofluid converter of the type specified in the preamble of claim 1.

Elektrofluidische Wandler, wie elektropneumatische und elektrohydraulische Wandler, die eine elektrische Eingangsgröße in eine fluidische, z.B. pneumatische oder hydraulische Ausgangsgröße Umsetzen und hierzu von Elektromagneten oder Piezoventilen betätigte Fluidventile besitzen, finden eine weitverbreitete Anwendung in der industriellen Steuertechnik für Werkzeugmaschinen. Die Zahl der für eine Werkzeugmaschinensteuerung erforderlichen Wandler ist dabei sehr groß und entsprechend steigt der Installationsaufwand, da alle Wandler einzeln angeschlossen und somit alle Wandler manuell kontaktiert werden müssen, um sie über Steuerleitungen mit der zentralen Steuereinrichtrnng zu verbinden.Electrofluidic converters, such as electropneumatic and electrohydraulic converters, which convert an electrical input variable into a fluid, for example pneumatic or hydraulic output variable and have fluid valves actuated by electromagnets or piezo valves for this purpose, are widely used in industrial control technology for machine tools. The number of converters required for machine tool control is very large and the installation effort increases accordingly, since all converters have to be connected individually and therefore all converters have to be contacted manually in order to connect them to the central control device via control lines.

Eine bekannte Wandlervorrichtung mit zwei in einem Wandlergehäuse angeordneten, elektrofluidischen, z.B. elektrohydraulischen oder elektropneumatischen Wandlern (DE 196 32 691 A1) weist eine am Wandlergehäuse ausgebildete Kontaktierungsvorrichtung auf, bei der in einer Gehäuseöffnung ein Leitungsabschnitt eines zweiadrigen Anschlußkabels, das zur Stromversorgung und Übertragung von Steuersignalen dient, eingelegt wird und an einem klappbaren Gehäusedeckel eine Klemmvorrichtung ausgebildet ist. Beim Andrücken des Gehäusedeckels an das Wandlergehäuse durchtrennt eine Trennschneide der Klemmvorrichtung das Anschlußkabel und auf die elektrischen Leiter der beiden getrennten Kabelabschnitte sich aufpressende Andruckflächen stellen eine elektrische Verbindung zwischen den elektrischen Leitern und den Anschlußkontakten einer elektronischen Schaltung her. Mittels dieser Kontaktierungseinheit kann eine Vielzahl von Wandlern in kürzester Zeit an das Anschlußkabel angesetzt und kontaktiert werden.A known transducer device with two electrofluidic, e.g. Electrohydraulic or electropneumatic transducers (DE 196 32 691 A1) has a contacting device formed on the transducer housing, in which a line section of a two-wire connection cable, which serves for the power supply and transmission of control signals, is inserted in a housing opening and a clamping device is formed on a hinged housing cover . When the housing cover is pressed onto the converter housing, a cutting edge of the clamping device cuts through the connecting cable and pressure surfaces which are pressed onto the electrical conductors of the two separate cable sections establish an electrical connection between the electrical conductors and the connecting contacts of an electronic circuit. Using this contacting unit, a large number of transducers can be attached to the connecting cable and contacted in the shortest possible time.

Der Erfindung liegt die Aufgabe zugrunde, einen Stecker der eingangs genannten Art zum Anschluß von einzelnen Wandlern an ein zu einer Steuereinheit führendes Anschlußkabel so zu verbessern, daß sowohl der Installationsaufwand als auch die Installationszeit für die Einrichtung der Maschinensteuerung gesenkt werden kann.The invention has for its object to improve a connector of the type mentioned for connecting individual transducers to a connecting cable leading to a control unit so that both the installation effort and the installation time for setting up the machine control can be reduced.

Die Aufgabe ist bei einem Stecker der im Oberbegriff des Anspruchs 1 definierten Gattung erfindungsgemäß durch die Merkmale im Anspruch 1 gelöst.The object is achieved according to the invention in a plug of the type defined in the preamble of claim 1 by the features in claim 1.

Der erfindungsgemäße Stecker zum Anschließen eines elektrofluidischen Wandlers hat den Vorteil, daß der Stecker innerhalb des Steckergehäuses voll verdrahtet ist und vor oder nach dem Aufstecken auf die Steckkontakte des Wandlers werkzeuglos und schnell die elektrische Verbindung zu dem Anschlußkabel hergestellt werden kann, wozu lediglich das Kabel in das bewegliche Kabelaufnahmeteil eingelegt und der Klemmhebel manuell geschlossen werden muß. Die Beweglichkeit des Aufnahmeteils sorgt dabei für eine exakte Ausrichtung des Kabels ohne Verkantungsgefahr beim Aufpressen des Klemmhebels und gewährleistet in jedem Fall eine zuverlässige Kontaktierung der Verbindungsmittel mit den Kabeladern. Mit Schließen des Klemmhebels ist der Stecker sowohl elektrisch an das Anschlußkabel angeschlossen als auch mechanisch und spritzwassergeschützt an dem Anschlußkabel festgelegt. Eine an dem Wandlergehäuse verschraubbare Befestigungsschraube, die durch eine Bohrung im Steckergehäuse hindurchgeführt ist, dient zur Sicherung und verhindert ein unbeabsichtigtes Abziehen oder Abfallen des Steckers vom Wandlergehäuse bei oder nach der Montage, z.B. bei Zugbelastung am Kabel.The plug according to the invention for connecting an electrofluid converter has the advantage that the plug is fully wired within the connector housing and that the electrical connection to the connecting cable can be made quickly and without tools before or after being plugged onto the plug contacts of the converter, for which purpose only Cable is inserted into the movable cable receptacle and the clamping lever must be closed manually. The mobility of the receiving part ensures an exact alignment of the cable without the risk of canting when the clamping lever is pressed on, and in any case ensures reliable contacting of the connecting means with the cable wires. When the clamping lever is closed, the plug is both electrically connected to the connecting cable and mechanically and splash-proof on the connecting cable. A fastening screw that can be screwed to the converter housing and that is passed through a hole in the connector housing serves for securing purposes and prevents the connector from being unintentionally pulled off or falling off during or after installation, for example in the event of a tensile load on the cable.

Zweckmäßige Ausführungsformen des erfindungsgemäßen Steckers mit vorteilhaften Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen angegeben.Expedient embodiments of the plug according to the invention with advantageous developments and refinements of the invention are specified in the further claims.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist an dem Kabelaufnahmeteil eine mit dem Klemmhebel zusammenwirkende Zentriernase vorgesehen, auf der sich der Klemmhebel beim Aufschwenken auf das Kabelaufnahmeteil aufsetzt, so daß die vom Klemmhebel erzeugte Klemmkraft mittig und zentral auf das Aufnahmeteil übertragen wird.According to a preferred embodiment of the invention, a centering lug cooperating with the clamping lever is provided on the cable receiving part, on which the clamping lever sits when it is pivoted onto the cable receiving part, so that the clamping force generated by the clamping lever is transmitted centrally and centrally to the receiving part.

Dabei ist gemäß einer vorteilhaften Ausführungsform der Erfindung das Kabelaufnahmeteil in einem im Steckergehäuse ausgebildeten Schacht angeordnet, über dessen Schachtgrund die elektrischen Anschlußmittel mit Kontaktspitzen vorstehen, und im Abstand von dem Schachtboden sind in die Schachtwände Rastausnehmungen eingelassen, in die am Kabelaufnahmeteil ausgebildete Rastnasen eingreifen. Die aus Rastausnehmungen und Rastnasen bestehende Rastverbindung ist so ausgelegt, daß durch eine vom Klemmhebel aufgebrachte Druckkraft auf das Kabelaufnahmeteil die Rastnasen aus den Rastausnehmungen austreten und das Kabelführungsteil zum Verschieben zum Schachtboden hin freigeben, wo die Kontaktspitzen durch entsprechende Durchtrittsöffnungen im Boden des Kabelaufnahmeteils hindurchtreten und sich in das Kabel so einbohren, daß die im Kabel verlaufenden elektrischen Leiter kontaktiert werden.According to an advantageous embodiment of the invention, the cable receiving part is arranged in a shaft formed in the plug housing, over the bottom of the shaft the electrical connection means projecting with contact tips, and at a distance from the shaft bottom, recesses are made in the shaft walls, into which locking lugs formed on the cable receiving part engage. The locking connection consisting of locking recesses and locking lugs is designed such that the locking lugs from the locking recesses are exerted on the cable receiving part by a pressure force exerted by the clamping lever emerge and release the cable routing part for sliding towards the shaft floor, where the contact tips pass through corresponding through openings in the bottom of the cable receiving part and drill into the cable in such a way that the electrical conductors running in the cable are contacted.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist die Kontaktierungseinrichtung eine Trennschneide zum Durchtrennen des Kabelabschnitts der zu dessen Erstreckung auf, die bei auf das Kabelaufnahmeteil wirkendem Klemmhebel durch einen im Boden des Kabelaufnahmeteils ausgebildeten Schlitz hindurchtritt. Diese konstruktive Gestaltung macht es möglich, mit einem Stecker zwei in einem Wandlergehäuse integrierte Wandler zu kontaktieren bzw. Dateneingang und Datenausgang zu trennen und den Stecker in einfacher und zeitsparender Weise an das Anschlußkabel anzuschließen. Im Schachtgrund jeweils eine Kontaktspitze umschließende Dichtungskonturen sorgen in Verbindung mit der flexiblen Kabelisolation für eine flüssigkeitsdichte Verbindung zwischen den Kontaktspitzen und der Ummantelung des Kabelabschnitts, so daß keine Feuchtigkeit in die Kontaktstellen eintreten kann.According to an advantageous embodiment of the invention, the contacting device has a cutting edge for severing the cable section to extend it, which, when the clamping lever acts on the cable receiving part, passes through a slot formed in the bottom of the cable receiving part. This structural design makes it possible to use a plug to contact two converters integrated in a converter housing or to separate data input and data output and to connect the plug to the connecting cable in a simple and time-saving manner. Sealing contours enclosing a contact tip in the shaft bottom in conjunction with the flexible cable insulation ensure a liquid-tight connection between the contact tips and the sheathing of the cable section, so that no moisture can enter the contact points.

Auf der Oberseite des Deckels 25 steht eine Zentriernase 26 vor, die mit dem Klemmhebel 22 zusammenwirkt und eine mittels des Klemmhebels 22 erzeugte Druckkraft auf das Kabelaufnahmeteil 21 überträgt. Das Kabelaufnahmeteil 21 ist in einen im Steckergehäuse 16 ausgebildeten Schacht 27 eingesetzt, und zwar - wie Fig. 2 zeigt - mit zwei diametral angeordneten Rastnasen 28, die in der Schachtwand 27 ausgebildeten Rastausnehmungen 29 eingreifen. Dabei ist die aus Rastnasen 28 und Rastausnehmungen 29 gebildete Rastverbindung so ausgelegt, daß durch eine axiale Druckkraft auf die Zentriernase 26 am Kabelaufnahmeteil 21 die Rastnasen 28 nach unten aus den Rastausnehmungen 29 austreten und somit die Verschiebung des Kabelaufnahmeteils 21 im Schacht 27 in Richtung zum Schachtboden 271 ermöglichen. Aus dem Schachtboden 271 ragen die Kontaktspitzen 17 der Anschlußmittel 14 hervor. Fluchtend mit dem Kontaktspitzen 17 sind im Boden der Einlegewanne 24 des Kabelaufnahmeteils 21 Durchtrittsöffnungen 30 angeordnet, deren lichter Durchmesser größer ist als der Außendurchmesser der Kontaktspitzen 17.The contacting device 20, which can be operated without tools, has a movable receiving part 21 for inserting a cable section of the connecting cable 10, and a clamping lever 22 acting on the cable receiving part 21, which is fixed on the plug housing 16 so as to be pivotable about a pivot axis 23. The molded plastic receiving part 21 is made in two parts and has an insert tray 24 for the positive reception of the sheathed connecting cable 10 and a cover 25 pivotally formed on the insert tray 24, which can close the opening of the insert tray 24. On the upper side of the cover 25 there is a centering lug 26 which interacts with the clamping lever 22 and transmits a compressive force generated by the clamping lever 22 to the cable receiving part 21. The cable receiving part 21 is inserted into a shaft 27 formed in the plug housing 16, specifically - as shown in FIG. 2 - with two diametrically arranged locking lugs 28 which engage in the recesses 29 formed in the shaft wall 27. The locking connection formed from locking lugs 28 and locking recesses 29 is designed such that the locking lugs 28 emerge downward from the locking recesses 29 and thus the displacement of the cable receiving part 21 in the shaft 27 in the direction of the shaft bottom by an axial compressive force on the centering lug 26 on the cable receiving part 21 271 enable. The contact tips 17 of the connection means 14 protrude from the shaft floor 271. In alignment with the contact tips 17, through openings 30 are arranged in the bottom of the insertion trough 24 of the cable receiving part 21, the clear diameter of which is larger than the outer diameter of the contact tips 17.

Nach Aufstecken des Steckers mit seinen Gegenkontakten 13 auf die Wandler-Steckkontakte 12 wird das Steckergehäuse 16 mittels einer einzigen Befestigungsschraube 31, die durch eine Bohrung 32 im Steckergehäuse 16 hindurchgesteckt wird, in einem Gewindeloch im Wandlergehäuse 11 verschraubt. Dann wird der Anschluß des Steckers an das Anschlußkabel 10 mittels der Kontaktierungsvorrichtung 20 wie folgt durchgeführt, wobei auf die Darstellungen in Fig. 5 verwiesen wird.After the plug with its mating contacts 13 has been plugged onto the converter plug contacts 12, the plug housing 16 is screwed into a threaded hole in the converter housing 11 by means of a single fastening screw 31 which is inserted through a bore 32 in the plug housing 16. Then the connection of the plug to the connection cable 10 is carried out by means of the contacting device 20 as follows, reference being made to the representations in FIG. 5.

Bei hochgeschwenktem Klemmhebel 22 ist das Kabelaufnahmeteil 21 zugänglich, wobei Deckel 25 und Einlegewanne 24 so miteinander verbunden sind, daß der Deckel 25 mit einer in Öffnungsrichtung wirkenden Rückstellkraft beaufschlagt ist. Bei hochgeklapptem Klemmhebel 22 liegt somit die Einlegewanne 24 frei (Fig. 5a), und das Anschlußkabel 10 kann in die Einlegewanne 24 eingelegt werden (Fig. 5b). Danach wird der Klemmhebel 22 in Richtung auf das Steckergehäuse 16 hin verschwenkt (Fig. 5c), wodurch die Unterseite des Klemmhebels 22 sich auf die Zentriernase 26 aufsetzt und bei weiterem Schwenken des Klemmhebels 22 eine axiale Druckkraft auf das Kabelaufnahmeteil 21 aufgebracht wird. Dadurch wird das Kabelaufnahmeteil 21 aus den Rastausnehmungen 29 im Schacht 27 herausgedrückt und in Richtung zum Schachtboden 271 verschoben. Die Kontaktspitzen 17 treten durch die Durchtrittsöffnungen 30 im Schachtboden 271 hindurch, Durchbohren die Ummantelung 101 des Anschlußkabels 10 und dringen in die Kabeladern 102 und 103 des Anschlußkabels 10 ein, um dort einen elektrischen Kontakt herzustellen. Damit sind die Anschlußmittel 14 elektrisch am Anschlußkabel 10 kontaktiert und über die Verbindungsmittel 15, den Gegenkontakten 13 und den Wandler-Steckkontakten 12 der Wandler an das Anschlußkabel 10 angeschlossen. Der Klemmhebel 22 wird schließlich mittels einer Rastverbindung 33 am Deckelgehäuse 16 verrastet, so daß er über die Zentriernase 26 das Kabelaufnahmeteil 21 am Schachtboden 271 kraftschlüssig festliegt. Das formschlüssig in die Einlegewanne 24 eingelegte Anschlußkabel 10 wird von dem Deckel 25 in der Einlegewanne 24 festgeklemmt, so daß das Anschlußkabel 10 auch mechanisch am Stecker festgelegt ist (Fig. 5d). Das Anschlußkabel 10 führt zu einer zentralen Steuereinheit, von welcher aus der Wandler mittels Steuersignale selektiv angesteuert wird. In dem Steckergehäuse 16 angeordnete Leuchtanzeigen, die z.B. als auf der Leiterkarte 18 angeordnete Dioden ausgebildet sind, signalisieren durch Aufleuchten den Schaltzustand des Wandlers. Die Leuchtanzeigen 34 sind durch ein im Steckergehäuse 16 ausgebildetes Fenster 35 hindurch sichtbar. Weitere Einzelheiten im Steckergehäuse 16, wie Erdungsschraube 36 und Eingangsstecker 37 für Sensoren, seien hier nur am Rande vermerkt.When the clamping lever 22 is pivoted upwards, the cable receiving part 21 is accessible, the cover 25 and the insert trough 24 being connected to one another in such a way that the cover 25 is acted upon by a restoring force acting in the opening direction. When the clamping lever 22 is folded up, the insert tray 24 is thus exposed (FIG. 5a), and the connecting cable 10 can be inserted into the insert tray 24 (FIG. 5b). Thereafter, the clamping lever 22 is pivoted in the direction of the plug housing 16 (FIG. 5c), as a result of which the underside of the clamping lever 22 sits on the centering lug 26 and, upon further pivoting of the clamping lever 22, an axial compressive force is applied to the cable receiving part 21. As a result, the cable receiving part 21 is pressed out of the locking recesses 29 in the shaft 27 and moved in the direction of the shaft bottom 271. The contact tips 17 pass through the through openings 30 in the shaft floor 271, pierce the sheath 101 of the connecting cable 10 and penetrate into the cable cores 102 and 103 of the connecting cable 10 in order to make electrical contact there. Thus, the connection means 14 are electrically contacted on the connection cable 10 and connected to the connection cable 10 via the connection means 15, the mating contacts 13 and the converter plug contacts 12 of the converter. The clamping lever 22 is finally locked by means of a latching connection 33 on the cover housing 16, so that it is non-positively fixed on the shaft base 271 via the centering lug 26. The form-fitting inserted in the insert tray 24 Connection cable 10 is clamped by the cover 25 in the insertion trough 24, so that the connection cable 10 is also mechanically fixed to the plug (FIG. 5d). The connecting cable 10 leads to a central control unit, from which the converter is selectively controlled by means of control signals. Luminous displays arranged in the plug housing 16, which are designed, for example, as diodes arranged on the circuit card 18, signal the switching state of the converter by lighting up. The illuminated displays 34 are visible through a window 35 formed in the plug housing 16. Further details in the connector housing 16, such as grounding screw 36 and input connector 37 for sensors, should only be mentioned here in passing.

Der in Fig. 3 im Längsschnitt dargestellte Stecker unterscheidet sich von dem vorstehend beschriebenen Stecker im wesentlichen durch eine Modifizierung der Kontaktierungsvorrichtung 20. Soweit Bauteile dieses Steckers mit Bauteilen des mit Fig. 1 und 2 beschriebenen Steckers übereinstimmen, sind sie mit gleichen Bezugszeichen versehen. In Fig. 3 ist dabei eine Draufsicht des modifizierten Steckers in Richtung Pfeil IV in Fig. 3 dargestellt, wobei der am Steckergehäuse 16 angelenkte Klemmhebel 22 aufgeklappt und das Kabelaufnahmeteil 21 aus seiner in Fig. 3 dargestellten Rastverbindung im Schacht 27 herausgenommen ist. Die Anschlußmittel 14 weisen insgesamt vier Kontaktspitzen 17 auf, die über die Verbindungsmittel 15 mit Gegenkontakten 13 für insgesamt zwei im Wandlergehäuse 11 angeordnete elektrische Eingangsteile zweier Wandler angeschlossen sind. Die vier Kontaktspitzen 17 ragen in gleicher Weise durch den Schachtboden 271 in den Schacht 27 hinein und stehen mit einem Abstandsmaß über den Schachtboden 271 vor. Im Boden der Einlegewanne 24 des Kabelaufnahmeteils 21 sind insgesamt vier Durchtrittsöffnungen 30 für jeweils eine Kontaktspitze 17, sowie ein Schlitz zum Durchtritt einer Trennschneide 38 vorgesehen, die zwischen zwei Paaren von Kontaktspitzen 17 quer zur Erstreckungsrichtung des Anschlußkabels 10 am Schachtboden 271 vertikal von diesem abstehend angeordnet ist. Die Trennschneide 38 ist so ausgebildet, daß sie bei dem zu Fig. 1 beschriebenen Vorgang des Aufschwenkens des Klemmhebels 22 auf das Steckergehäuse 16 und des dadurch bewirkten Nachuntendrückens des Kabelaufnahmeteils 21 in Richtung zum Schachtboden 271 das Anschlußkabel 10 zu durchtrennen vermag, so daß im Kabelaufnahmeteil 21 zwei voneinander getrennte Kabelabschnitte voneinander isoliert elektrisch kontaktiert und mechanisch festgeklemmt sind.The plug shown in longitudinal section in FIG. 3 differs from the plug described above essentially by a modification of the contacting device 20. As far as components of this plug match components of the plug described with FIGS. 1 and 2, they are provided with the same reference numerals. 3 shows a top view of the modified plug in the direction of arrow IV in FIG. 3, the clamping lever 22 articulated on the plug housing 16 being opened and the cable receiving part 21 being removed from its snap-in connection in the shaft 27 shown in FIG. 3. The connection means 14 have a total of four contact tips 17, which are connected via the connection means 15 with mating contacts 13 for a total of two electrical input parts of two transducers arranged in the converter housing 11. The four contact tips 17 project in the same way through the shaft floor 271 into the shaft 27 and protrude beyond the shaft floor 271 with a spacing. A total of four through openings 30 for one contact tip 17 each, and a slot for the passage of a cutting edge 38 are provided in the bottom of the insert trough 24 of the cable receiving part 21, and between two pairs of contact tips 17 transversely to the direction of extension of the connecting cable 10 on the shaft floor 271 is arranged vertically projecting from the latter. The cutting edge 38 is designed such that it can cut through the connecting cable 10 in the process of pivoting the clamping lever 22 onto the plug housing 16 and thus causing the cable receiving part 21 in the direction of the shaft bottom 271 to be severed, so that in the cable receiving part 21 two separate cable sections are electrically insulated from each other and mechanically clamped.

Wie in Fig. 4 dargestellt ist, ist an jeder aus dem Schachtboden 271 hervorstehende Kontaktspitze 17 ein Dichtungskontur 39 angeordnet, der die zugeordnete Kontaktspitze 17 umschließt und zusammen mit der flexiblen Kabelisolation für eine Abdichtung sorgt. Durch diese Dichtungsringe 39 wird beim Einpressen des Anschlußkabels 10 in die Kontaktierungsvorrichtung 20 mit Durchtrennen des Anschlußkabels 10 durch die Trennschneide 38 eine flüssigkeitsdichte Verbindung zwischen dem Steckergehäuse 16 und der Ummantelung der voneinander getrennten Kabelabschnitte hergestellt, so daß keine Feuchtigkeit oder kein Wasser an die Kontaktierungsstellen von Kontaktspitzen 17 und Kabeladern 102,103 gelangen kann.As shown in FIG. 4, a sealing contour 39 is arranged on each contact tip 17 protruding from the shaft bottom 271, which surrounds the associated contact tip 17 and provides a seal together with the flexible cable insulation. Through these sealing rings 39 is a liquid-tight connection between the connector housing 16 and the sheathing of the separated cable sections is made when pressing the connecting cable 10 into the contacting device 20 by cutting the connecting cable 10 by the cutting edge 38, so that no moisture or no water to the contact points of Contact tips 17 and cable wires 102, 103 can reach.

In einer Modifizierung der Kontaktierungsvorrichtung 20 ist das Kabelaufnahmeteil 21 parallel zur Trennschneide 28 zweigeteilt ausgeführt, so daß im Schacht 27 zwei gleich ausgebildete Kabelführungsteilabschnitte rechts und links der Trennschneide 38 vorhanden sind. Jeder Teilabschnitt weist eine separate Einlegewanne 24 und einen separaten Deckel 25 mit aufgesetzter Zentriernase 26 auf. Diese Zweiteilung des Kabelaufnahmeteils 21 hat den Vorteil, daß sich die beiden durch die Trennschneide 38 beim Aufklemmvorgang getrennten Kabelabschnitte des Anschlußkabels 10 unabhängig voneinander aus der Kontaktierungsvorrichtung 20 lösen lassen.In a modification of the contacting device 20, the cable receiving part 21 is made in two parts parallel to the cutting edge 28, so that in the shaft 27 there are two identically designed cable guide sections on the right and left of the cutting edge 38. Each section has a separate insert trough 24 and a separate cover 25 with a centering lug 26 attached. This division of the cable receiving part 21 into two parts has the advantage that the two cable sections of the connecting cable 10 separated by the cutting edge 38 during the clamping process can be detached from the contacting device 20 independently of one another.
