Description

Die vorliegende Erfindung betrifft ein Beschaltungswerkzeug für den Schwachstrom-Anlagebau, insbesondere für die Beschaltung der Anschlussleisten von Verteiler-Anlagen mit Kabeladern und Rangierdrähten, mit einem, in einem Griff über einen Schlagmechanismus relativ zum Griff verschiebbar abgestützten, unter der Wirkung eines gegen Federmittel ausgeübten Druckes betätigbaren, einen Draht in einen Kontaktschlitz eines Anschlusselementes eindrückenden Beschaltungskopf, von welchem innenseitig ein Stössel abragt, dessen inneres Ende mit einem druckfederbelasteten Schlitten des Schlagmechanismus über einen, gegen die Kraft einer Feder seitlich bewegbaren Sperrschieber in lösbarer Wirkungsverbindung steht.
Beschaltungswerkzeuge der vorgenannten Art sind etwa durch die DE-A-2538558 bekannt geworden und dienen der Arbeitserleichterung beim Verdrahten von Verteiler-Anlagen u. dgl. beispielsweise in der Uebertragungstechnik und Telefonie, wo an eine grosse Anzahl Mehrfach-Anschlussleisten Kabeladern und Rangierdrähte anzuschliessen sind. Eine solche Anschlusstechnik zum löt-, schraub- und abisolierfreien Anschliessen von isolierten Leiterdrähten an die Klemmkontakte der Anschlussleisten wurde u.a. von der Anmelderin entwickelt, welche inzwischen unter der Bezeichnung VS 83 weltweite Verbreitung gefunden hat.
The present invention relates to a wiring tool for low-current system construction, in particular for the wiring of the terminal strips of distribution systems with cable cores and jumper wires, with a support that is displaceable in a handle via a striking mechanism relative to the handle, under the action of a pressure exerted against spring means Actuable, a wire into a contact slot of a connection element, the wiring head, from which a plunger protrudes on the inside, the inner end of which with a compression spring-loaded slide of the striking mechanism via a locking slide that can be moved laterally against the force of a spring in a detachable operative connection stands.
Wiring tools of the aforementioned type have become known, for example, from DE-A-2538558 and serve to make work easier when wiring distribution systems and the like. The like, for example, in transmission technology and telephony, where cable cores and jumper wires are to be connected to a large number of multiple connection strips. Such a connection technology for solder-free, screw-free and stripping-free connection of insulated conductor wires to the terminal contacts of the terminal strips was developed by the applicant, which has meanwhile found worldwide use under the name VS 83.

Entsprechend besteht auch ein hoher Bedarf an Beschaltungswerkzeugen der vorgenannten Art.Accordingly, there is also a high demand for wiring tools of the aforementioned type.

Ein grosser Nachteil bei solchen Beschaltungswerkzeugen besteht aber nur in deren kurzer Lebensdauer infolge enormer Verschleisserscheinungen am Schlagmechanismus, indem dort ein Sperrschieber rechtwinklig zur Betätigungsrichtung des Beschaltungswerkzeuges verschoben werden muss, um den gewünschten Schlag am Ende des Beschaltungsvorganges zu bewirken.A major disadvantage of such wiring tools is their short lifespan due to the enormous wear and tear on the striking mechanism, where a locking slide must be moved at right angles to the actuation direction of the wiring tool in order to achieve the desired stroke at the end of the wiring process.

Es ist somit Aufgabe der vorliegenden Erfindung, ein Beschaltungswerkzeug der vorgenannten Art so auszugestalten, dass dessen Lebensdauer entscheidend erhöht werden kann.It is therefore an object of the present invention to design a wiring tool of the aforementioned type in such a way that its service life can be decisively increased.

Dies wird erfindungsgemäss zunächst dadurch erreicht, dass der Sperrschieber mit einer vorzugsweise 45°-Neigung vor der mit gleicher Neigung versehenen freien Stirnseite des Stössels auf einer entsprechenden stirnseitigen Verschiebungsfläche des Schlittens angeordnet ist, wobei der Sperrschieber mit einer Querlasche direkt oder indirekt an einer Anschlag- und Führungsfläche am Handgriff anliegt zur Erzeugung der Querverschiebung des Sperrschiebers bei Axialverschiebung des Stössels bis zur, eine schlagartige Rückstellung bewirkenden Freigabe des Stössels durch Eintritt in eine Durchbrechung im Sperrschieber.According to the invention, this is initially achieved in that the locking slide, preferably with a 45 ° inclination, is arranged in front of the free end face of the plunger provided with the same inclination on a corresponding frontal displacement surface of the slide, the locking slide being directly or indirectly connected to a stop plate with a transverse link. and the guide surface rests on the handle in order to generate the transverse displacement of the locking slide upon axial displacement of the plunger until the plunger is released suddenly by resetting through an opening in the locking slide.

Wie leicht erkennbar, werden durch diese Massnahmen zunächst die wirksamen Normalkräfte erheblich herabgesetzt. Zudem wird durch die Schräganordnung eine Vergrösserung der Kontaktflächen erreicht und somit der Flächendruck pro Flächeneinheit bei gleicher Auslösekraft vermindert, was die Reibung herabsetzt. Damit erfolgt aber auch eine Verminderung der Abnützungen an den beteiligten Elementen.As can easily be seen, these measures initially significantly reduce the effective normal forces. In addition, the inclined arrangement increases the contact areas and thus reduces the surface pressure per unit area with the same triggering force, which reduces the friction. However, this also reduces wear on the elements involved.

Um dabei die schlagartige Rückstellkraft verteilt aufnehmen zu können, besteht eine vorteilhafte Ausgestaltung des erfindungsgemässen Beschaltungswerkzeuges darin, dass stösselseitig am Sperrschieber ein, eine Gegenführungsfläche bildender, über eine Feder innenseitig am Beschaltungskopf axial verschiebbar abgestützter, die schlagartige Rückstellkraft aufnehmender Schlagkopf anliegt.In order to be able to absorb the abrupt restoring force in a distributed manner, an advantageous embodiment of the wiring tool according to the invention resides in that a plunger on the ram on the locking slide forms a counter guide surface that is axially displaceably supported by a spring on the wiring head and absorbs the abrupt resetting force.

Damit ergibt sich eine vorteilhafte Ausgestaltung darin, dass sich der Sperrschieber in seiner Verschiebungsrichtung über eine Rückstellfeder am Schlagkopf abstützt, wobei dann vorteilhaft die Querlasche über ein Gleitstück an einer gegengeneigten Führungsfläche anliegt.This results in an advantageous embodiment in that the locking slide is supported in its direction of displacement via a return spring on the striking head, in which case the transverse link advantageously bears against a counter-inclined guide surface via a slide piece.

Um mit solchen Beschaltungswerkzeugen nun sogenannte Installationsdrähte und Montagedrähte anschliessen zu können, die von unterschiedlicher Dicke sowohl bezüglich Drahtdurchmesser als auch bezüglich Dicke der Isolation sind, ergibt sich die Notwendigkeit, am Beschaltungswerkzeug den Schlagmechanismus regelbar zu machen, um den Beschaltungsvorgang dem betreffenden Draht anzupassen.In order to be able to connect so-called installation wires and assembly wires with such wiring tools, which are of different thickness both with regard to wire diameter and with respect to the thickness of the insulation, there is the need to make the striking mechanism adjustable on the wiring tool in order to adapt the wiring process to the wire in question.

Dies wird nun erfindungsgemäss dadurch erreicht, dass die Anschlag- und Führungsfläche von der Steuerkurve eines am Handgriff abgestützten, in mindestens zwei unterschiedliche, in Verschiebungsrichtung des Sperrschiebers zur früheren oder späteren Freigabe des Stössels wirksame Extremlagen verstellbaren Stellnockens gebildet ist.This is now achieved according to the invention in that the stop and guide surface is formed by the control cam of an adjusting cam supported on the handle and adjustable in at least two different extreme positions effective in the direction of displacement of the locking slide for earlier or later release of the ram.

Durch diese Massnahmen lässt sich bei entsprechender Ausbildung des Nockens entweder eine mehrstufige oder auch eine stufenlose Verstellung des Sperrschiebers in seiner Verschiebungsrichtung erreichen, so dass der Stössel früher oder später in die Durchbrechung des Sperrschiebers eintreten kann, so dass die schlagartige Rückstellung früher mit geringerer bzw. später mit grösserer Rückstellkraft ausgelöst wird.With appropriate training of the cam, these measures can either achieve a multi-stage or also a continuous adjustment of the locking slide in its direction of displacement, so that the plunger can enter the opening of the locking slide sooner or later, so that the sudden resetting earlier is triggered with less or later with greater restoring force.

Das dargestellte Beschaltungswerkzeug umfasst einen aus vorzugsweise zwei Gehäuse-Halbschalen 3' und 3'' gebildeten Griff 3. Am freien Ende dieses Griffes 3 ist ein sogenannter Beschaltungskopf 12 angeordnet, um einen Draht in einen Kontaktschlitz einer nicht näher gezeigten Anschlussleiste eindrücken zu können. Hierfür weist der Beschaltungskopf 12 einen zum Kontaktschlitz der Anschlussleiste achsenparallelen Eindrückstempel 13 auf, der an seinen beiden Enden durch querverlaufende, an der Anschlussleiste ansetzbare, vorzugsweise als Drahtklemmen ausgebildete Anschläge 14 und 15 begrenzt ist. Dies ist ansich bekannt und muss nicht näher erläutert werden.The wiring tool shown comprises a handle 3, which is preferably formed from two housing half-shells 3 'and 3' '. At the free end of this handle 3, a so-called wiring head 12 is arranged in order to be able to press a wire into a contact slot of a terminal block (not shown in more detail). For this purpose, the wiring head 12 has an indentation stamp 13 which is parallel to the contact slot of the terminal block and is delimited at both ends by transverse stops 14 and 15 which can be attached to the terminal block and are preferably designed as wire clamps. This is known per se and need not be explained in more detail.

Weiter ist bekannt, dass der Beschaltungskopf 12 mit einer Klinge 16 in Wirkungsverbindung steht, die gegen eine der hier vom Anschlag 14 gebildeten Drahtführungskanten hin eine den betreffenden Draht trennende Querbewegung um einen Drehzapfen 18 am Beschaltungskopf 12 ausführt. Am inneren Ende der Klinge 16 ist zur Auslösung der Querbewegung eine Kulisse 17 vorgesehen, in die ein gehäusefester Zapfen 5 eingreift. Im Bewegungsablauf des Klemmvorganges wird dann die bewegliche Klinge 16 derart verschwenkt, dass die am vorderen Ende ausgebildete Schneide 16' den Draht in einem vorgegebenen Abstand zur Klemmverbindung trennt.Furthermore, it is known that the wiring head 12 is operatively connected to a blade 16 which points against one of the wire guide edges formed here by the stop 14 executes a transverse movement separating the wire in question about a pivot pin 18 on the wiring head 12. At the inner end of the blade 16, a link 17 is provided to trigger the transverse movement, in which a pin 5 fixed to the housing engages. In the course of the movement of the clamping process, the movable blade 16 is then pivoted in such a way that the cutting edge 16 ′ formed at the front end separates the wire at a predetermined distance from the clamping connection.

Bekannt ist ferner, dass der Beschaltungskopf 12 über einen Schlagmechanismus 20 relativ zum Griff 3 verschiebbar und unter der Wirkung eines gegen Federmittel 4, 10 von Hand ausgeübten Druckes betätigbar im Griff 3 abgestützt ist. Hierfür ragt vom Beschaltungskopf 12 innenseitig ein Stössel 2 ab, dessen inneres Ende mit einem, von einer Druckfeder 4 belasteten Schlitten 8 über einen, gegen die Kraft einer Feder 9 seitlich bewegbaren Sperrschieber 7 in lösbarer Wirkungsverbindung steht.It is also known that the wiring head 12 can be displaced relative to the handle 3 by means of a striking mechanism 20 and can be actuated in the handle 3 under the action of pressure exerted by hand against spring means 4, 10. For this purpose, a plunger 2 protrudes from the inside of the wiring head 12, the inner end of which is in releasable operative connection with a slide 8 loaded by a compression spring 4 via a locking slide 7 which can be moved laterally against the force of a spring 9.

Um nun die bisherigen hohen Abnützungserscheinungen am Schlagmechanismus wirksam zu hindern, ist der Sperrschieber 7 nunmehr mit einer vorzugsweise 45°-Neigung zur Symmetrieebene vor der mit gleicher Neigung versehenen freien Stirnseite 2' des Stössels 2 auf einer entsprechenden stirnseitigen Verschiebungsfläche 8' des Schlittens 8 angeordnet.In order to effectively prevent the previous high signs of wear on the striking mechanism, the locking slide 7 is now arranged with a preferably 45 ° inclination to the plane of symmetry in front of the free end face 2 ′ of the plunger 2 provided with the same inclination on a corresponding frontal displacement surface 8 ′ of the slide 8 .

Weiter liegt der Sperrschieber 7 mit einem Gleitstück 21 an einer gegengeneigten Führungsfläche 22 am Handgriffgehäuse 3 an, um die Querverschiebung des Sperrschiebers 7 bei der Axialverschiebung des Stössels 2 bis zur, eine schlagartige Rückstellung bewirkenden Freigabe des Stössels 2 durch Eintritt in eine Durchbrechung 23 im Sperrschieber 7 zu erzeugen.Furthermore, the locking slide 7 rests with a slider 21 on a counter-inclined guide surface 22 on the handle housing 3 in order to prevent the transverse displacement of the locking slide 7 during the axial displacement of the plunger 2 until the plunger 2 is released suddenly by entering an opening 23 in the locking slide 7 to generate.

Weiter liegt stösselseitig am Sperrschieber 7 ein, eine Gegenführungsfläche 23′ bildender, über eine Feder 10 innenseitig am Beschaltungskopf 12 axial verschiebbar abgestützter Schlagkopf 23'' an, welcher die schlagartige Rückstellkraft aufnimmt. Hierbei stützt sich der Sperrschieber 7 in seiner Verschiebungsrichtung über eine Rückstellfeder 9 am Schlagkopf 23'' ab.Next is on the ram on the locking slide 7, a counter-guide surface 23 'forming, via a spring 10 on the inside of the wiring head 12 axially displaceably supported striking head 23' ', which absorbs the sudden restoring force. Here, the locking slide 7 is supported in its direction of displacement via a return spring 9 on the striking head 23 ″.

Dies ergibt eine verschleissarme, absolut funktionssichere und einfache Konzeption des Beschaltungswerkzeuges.This results in a low-wear, absolutely functionally reliable and simple design of the wiring tool.

Um das vorbeschriebene und selbstverständlich auch ein bereits bestehendes Beschaltungswerkzeug der hier infrage stehenden Art universell für unterschiedliche Anschluss-Systeme, insbesondere mit in der Breite variierenden Anschlussleisten verwenden zu können, ist ferner erfindungsgemäss vorgesehen, den von der Klinge 16 entfernten Anschlag 15 bzw. Drahtklemme als eine, am Beschaltungskopf 12 ortsfest angeordnete Blattfeder auszubilden.In order to be able to use the above-described and, of course, an already existing wiring tool of the type in question here universally for different connection systems, in particular with terminal strips that vary in width, the stop 15 or wire clamp removed from the blade 16 is also provided according to the invention to form a fixed leaf spring on the wiring head 12.

Diese Massnahme gestattet eine selbsttätige Anpassung der lichten Weite zwischen den zentrierenden Anschlägen 14 und 15 an unterschiedliche Breiten von Anschlussleisten unterschiedlicher Systeme. Zudem wird durch das nun nachgiebige Ansetzen des Beschaltungswerkzeuges dessen Handhabung bedienungsfreundlicher.This measure allows the clear width between the centering stops 14 and 15 to be automatically adapted to different widths of connection strips of different systems. In addition, the flexible application of the wiring tool makes it easier to use.

Bei Beschaltungswerkzeugen der vorbeschriebenen Art ist es üblich, dieses an Ort von einem mit wirksamer Draht-Trennfunktion in ein solches ohne Draht-Trennfunktion umzurüsten.In the case of wiring tools of the type described above, it is customary to convert them on-site from one with an effective wire-cutting function into one without a wire-cutting function.

Hierfür ist, wie vorbeschrieben, eine Klinge 16 vorgesehen, die gegen eine Kante am Anschlag 14 bzw. an der Drahtklemme hin eine den betreffenden Draht trennende Querbewegung um einen Drehzapfen 18 am Beschaltungskopf 12 ausführt. Diese Klinge 16 ist an ihrem inneren Ende mit einer Kulisse 17 versehen, in die ein gehäusefester Zapfen 5 eingreift. Im Bewegungsablauf des Klemmvorganges wird dann die bewegliche Klinge 16 derart verschwenkt, dass die am vorderen Ende ausgebildete Schneide den Leiterdraht in einem vorgegebenen Abstand zur Klemmverbindung abtrennt.For this purpose, as described above, a blade 16 is provided which, against an edge on the stop 14 or on the wire clamp, executes a transverse movement separating the wire in question about a pivot pin 18 on the wiring head 12. This blade 16 is provided at its inner end with a link 17 into which a pin 5 fixed to the housing engages. In the course of the movement of the clamping process, the movable blade 16 is then pivoted in such a way that the cutting edge formed at the front end cuts off the conductor wire at a predetermined distance from the clamping connection.

Um nun dieses Beschaltungswerkzeug in ein solches ohne Draht-Trennfunktion umrüsten zu können, ist die Klinge 16 in Längsrichtung des Beschaltungskopfes 12 bezüglich des Drehzapfens 18 zwischen zwei Schwenkstellungen 35, 36 versetzbar, von denen die von der Drahtführungskante 14' der Drahtklemme 14 am Beschaltungskopf 12 entferntere Stellung 35 die unwirksame Lage und die nähere Stellung 36 die wirksame Lage der Klinge 16 bestimmen.In order to be able to convert this wiring tool into one without a wire separation function, the blade 16 can be displaced in the longitudinal direction of the wiring head 12 with respect to the pivot pin 18 between two pivot positions 35, 36, of which the position 35 farther from the wire guide edge 14 'of the wire clamp 14 on the wiring head 12 determines the ineffective position and the closer position 36 determines the effective position of the blade 16.

Um weiter die vorbeschriebene Anordnung noch universeller auszugestalten, ist erfindungsgemäss vorgesehen, die Klinge 16 zwischen der einen Stellung, in welcher deren Funktion durch die Axialverschiebung des Beschaltungskopfes 12 bewirkbar ist, und einer zweiten Stellung versetzbar zu machen, in der deren Funktion durch einen an der Klinge 16 wirksamen, aus dem Gehäuse 3 ausschwenkbaren und gegen die Wirkung einer Feder 31 betätigbaren Hebel 30 bewirkt werden kann.In order to make the above-described arrangement even more universal, it is provided according to the invention to make the blade 16 displaceable between the one position in which its function can be effected by the axial displacement of the wiring head 12 and a second position in which its function can be performed by another Blade 16 effective lever 30 can be pivoted out of the housing 3 and actuated against the action of a spring 31.

In dieser Funktionslage kann das Beschaltungswerkzeug als normale Drahtschere benützt werden.In this functional position, the wiring tool can be used as a normal wire cutter.

Hierbei wird die Kopplung zwischen Klinge 16 und Hebel 30 über eine Kopplungsplatte 32 bewerkstelligt, die sich auswechselbar am Gehäuse 3 abstützt.Here, the coupling between the blade 16 and the lever 30 is accomplished via a coupling plate 32, which is interchangeably supported on the housing 3.

Um dabei in der unwirksamen, in das Gehäuse 3 vollständig eingeschwenkten Lage von Hebel 30 und Kopplungsplatte 31 die vorbeschriebene Versetzung der Klinge 16 in Längsrichtung des Beschaltungskopfes 12 in die unwirksame bzw. wirksame Lage ermöglichen zu können, ist in der Kopplungsplatte 32 eine entsprechende Kulisse 33 für die Relativverschiebung der Kulisse 33 zum gehäusefesten Zapfen 5 vorgesehen.In order to enable the above-described displacement of the blade 16 in the longitudinal direction of the wiring head 12 into the ineffective or effective position in the ineffective position of the lever 30 and the coupling plate 31 which is completely pivoted into the housing 3, is in the coupling plate 32 a corresponding link 33 for the relative displacement of the link 33 to the housing-fixed pin 5 is provided.

Das Anschliessen dickerer Drähte verlangt einen höheren Beschaltungsdruck auf das Werkzeug als dünnere Drähte, womit der Schlagmechanismus bei dickeren Drähten erst nach Ueberwindung einer grösseren Federvorspannung auslösen darf als bei dünneren Drähten. Umgekehrt soll der Schlagmechanismus bei dünneren Drähten nach Ueberwindung einer entsprechend geringeren Federvorspannung auslösen.The connection of thicker wires requires a higher wiring pressure on the tool than thinner wires, so that the striking mechanism with thicker wires can only trigger after a greater spring preload has been overcome than with thinner wires. Conversely, the striking mechanism should trigger on thinner wires after overcoming a correspondingly lower spring preload.

Um dies zu ermöglichen, ist gemäss Fig. 3 die Anschlagund Führungsfläche für die Querlasche 7′ am Sperrschieber 7 von der Steuerbahn 22′ bzw. 22'' eines Stellnockens 41 gebildet.To make this possible, the stop and guide surface for the transverse link 7 'on the locking slide 7 is formed by the control track 22' or 22 '' of an actuating cam 41 according to FIG. 3.

Dieser Stellnocken 41 ist mittels einer Feststellschraube 42 verdrehbar zwischen mindestens zwei unterschiedlichen Extremlagen 22′ bzw. 22'' am Handgriff 3 befestigt.This control cam 41 is rotatably fastened by means of a locking screw 42 between at least two different extreme positions 22 'and 22' 'on the handle 3.

Wie Fig. 3 deutlich zeigt, sind hier zwei Extremlagen 22′ bzw. 22'' vorgesehen, welche den Sperrschieber 7 in seiner Verschiebungsrichtung so verstellen, dass der Stössel 2 später bzw. früher in die Schieberöffnung 23 eintauchen und damit unter der Wirkung der stärker bzw. weniger vorgespannten Schlagfeder 4 den Rückstellschlag auslösen kann.As clearly shown in Fig. 3, here two extreme positions 22 'and 22''are provided which adjust the locking slide 7 in its direction of displacement so that the plunger 2 later or earlier plunge into the slide opening 23 and thus under the effect of the stronger or less biased spring 4 can trigger the return stroke.

Somit ergibt sich aus dem Vorstehenden ein Beschaltungswerkzeug für den Schwachstrom-Anlagebau, insbesondere für die Beschaltung der Anschlussleisten von Verteiler-Anlagen mit Kabeladern und Rangierdrähten, das gemäss den vorstehenden Forderungen universell einsetzbar ist und sich insbesondere durch eine abnützungsarme, hohe Lebensdauer und ermüdungsfreie Bedienbarkeit auszeichnet.The above results in a wiring tool for low-voltage plant construction, in particular for wiring the connection strips of distribution systems with cable wires and jumper wires, which can be used universally in accordance with the above requirements and is characterized in particular by a low-wear, long service life and fatigue-free operability .

Claims (5)
