Description

Die Erfindung betrifft eine Vorrichtung zum elektrisch leitenden Anklemmen einer isolierten Kabelader an ein aufrechtstehendes Kontaktelement, bestehend aus einem in einem Gehäuse längsverschiebbar angeordneten Stößel, der an seinem vorderen freien Ende ein Druckstück aufweist.The invention relates to a device for the electrically conductive connection of an insulated cable core to an upright contact element, consisting of a plunger arranged longitudinally displaceably in a housing and having a pressure piece at its front free end.

Die Erfindung ist insbesondere auf dem Gebiet der Fernmeldetechnik anwendbar, und zwar zum löt-, schraub- und abisolierfreien Beschalten von fernsprechtechnischen Anlagen.The invention is particularly applicable in the field of telecommunications, specifically for the soldering, screwing and stripping-free wiring of telephony systems.

Bei der von der Anmelderin entwickelten LSA-Anschlußtechnik werden mechanisch außerordentlich haltbare und gegen Korrosion dauerhaft geschützte elektrische Verbindungen zwischen einer Kabelader und einem Anschlußelement hergestellt, ohne daß zuvor das Kabel abisoliert werden müßte,oder daß Schraub- bzw. Lötverbindungen notwendig wären.In the LSA connection technology developed by the applicant, mechanically extremely durable and permanently protected against corrosion electrical connections between a cable core and a connecting element are made without first stripping the cable would have to be, or that screw or solder connections would be necessary.

Bei dieser LSA-Anschlußtechnik werden meist aufrecht in einem Träger befestigte Kontaktelemente verwendet, die mindestens einen Längsschlitz von vorgegebener Länge haben, dessen Breite etwas geringer als der Durchmesser des Leiterdrahtes ist. Ein Drahtende wird quer in diesen Schlitz hineingedrückt, wobei die in einem vorgegebenen Maß federnd verformbaren Schlitzbegrenzungen seitlich so verschoben werden, daß ihre scharfen Kanten die Isolierung durchschneiden und in einem vorgegebenen Maß in das Drahtmaterial eindringen.In this LSA connection technology, contact elements fastened upright in a carrier are usually used, which have at least one longitudinal slot of a predetermined length, the width of which is somewhat less than the diameter of the conductor wire. One end of the wire is pressed transversely into this slot, the slot boundaries which are resiliently deformable to a predetermined extent being laterally displaced such that their sharp edges cut through the insulation and penetrate the wire material to a predetermined extent.

Zur Durchführung eines derartigen Klemmvorganges sind Werkzeuge und Vorrichtungen bekannt, die in einem Gehäuse einen gegen Federkraft längsverschiebbar angeordneten Stößel und/oder Schieber aufweisen, welcher mit einem z. B. längsgeschlitzten Klemmkopf an seinem vorderen Endteil fest verbunden ist. Eine isolierte Kabelader wird in ein erweitertes Maul des Schlitzes lose eingelegt und nach Ansetzen des Klemmwerkzeuges durch eine von Hand oder motorisch erzeugte Vorschubbewegung des Stößels vom Schieber in den Schlitz eingedrückt. Durch Rückfedern eines Schnappmechanismus wird die Beendigung des Anschaltvorganges angezeigt.To carry out such a clamping process tools and devices are known which have a plunger and / or slide arranged longitudinally displaceably against spring force in a housing, which with a z. B. slotted clamping head is firmly connected at its front end part. An insulated cable core is loosely inserted into an enlarged mouth of the slot and, after the clamping tool has been attached, is pushed into the slot by the slide by a manual or motor-driven feed movement of the plunger. Springing back of a snap mechanism indicates the end of the connection process.

Bisher war es üblich, die Anschlußelemente zumindest teilweise außen an einem nachgiebigen Kunststoff abzustützen, so daß beim Eindrücken der Kabeladern die seitlich federnden Laschen eine ausreichende Halterung fanden. Diese seitliche Abstützung ist jedoch mit einem gewissen konstruktiven Aufwand verbunden und beansprucht insbesondere einen gewissen Platz, was dem Ziel einer Verkleinerung von Anschlußeinheiten bzw. einer Bestückung standardisierter Anschlußeinheiten mit einer größeren Zahl an Kabeladern Grenzen setzt.Previously, it was common to support the connecting elements at least partially on the outside on a resilient plastic, so that when the cable wires were pressed in, the laterally resilient tabs were adequately supported. However, this lateral support is associated with a certain amount of design and takes up a certain amount of space, which is the goal of a The reduction in the number of connection units or the assembly of standardized connection units with a larger number of cable cores sets limits.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Gattung zu schaffen, mit welcher elektrisch leitende Klemmverbindungen zwischen Kabeladern und aufrechtstehenden, seitlich nicht abgestützten Anschlußelementen sicher und auf einfache Weise hergestellt werden können.The object of the invention is to provide a device of the type mentioned at the beginning with which electrically conductive clamp connections between cable cores and upright, laterally unsupported connecting elements can be produced safely and in a simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Gehäuse eine den Stößel zumindest auf einem Teil seiner Länge umgebende Hülse angeordnet ist, deren freies, längsgeschlitztes Ende über das Druckstück vorsteht und vor sowie während des Klemmvorganges die Zungen des Kontaktelementes seitlich abstützt.This object is achieved in that a sleeve surrounding the plunger at least over part of its length is arranged in the housing, the free, longitudinally slotted end of which protrudes beyond the pressure piece and laterally supports the tongues of the contact element before and during the clamping process.

Zur Erzielung eines sicheren Formschlusses zwischen dem Drahtmaterial des Kabels und den scharfen Kanten des Kontaktelementes ist auch der vordere Endteil des Druckstückes so ausgebildet, daß sich die einen schrägen Mittelschlitz begrenzenden Seitenflächen zweier profilierter Längsstege an die entsprechenden Seitenflächen des Kontaktteiles des Anschlußelementes anlegen.In order to achieve a secure positive connection between the wire material of the cable and the sharp edges of the contact element, the front end part of the pressure piece is also designed such that the side surfaces of two profiled longitudinal webs delimiting an oblique central slot lie against the corresponding side surfaces of the contact part of the connection element.

Zu diesem Zweck weist das in der Hülse verschiebbare Druckstück einen den mittleren, längsgeschlitzten Kontaktteil des Kontaktelementes beidseitig fixierenden Schrägschlitz zwischen zwei Profilstegen auf.For this purpose, the pressure piece displaceable in the sleeve has an oblique slot, which fixes the middle, longitudinally slotted contact part of the contact element on both sides, between two profile webs.

Aufgrund der außerordentlich begrenzten Raumverhältnisse ist es sehr schwierig, die freistehenden Enden der Kabeladern mit gesonderten Werkzeugen, z. B. Scheren, abzutrennen. Daher besteht eine wesentliche Weiterbildung der Erfindung darin, daß ein Teil der Hülsenwand als Schneide ausgebildet ist, die nach erfolgter Klemmung durch eine weitergehende Vorschubbewegung der Vorrichtung zusammen mit einer am Druckstück ausgebildeten Schneidkante das Kabelende abtrennt.Due to the extremely limited space, it is very difficult to separate the free ends of the Ka load with separate tools, e.g. B. scissors to separate. Therefore, an essential development of the invention is that part of the sleeve wall is designed as a cutting edge which, after clamping, separates the cable end by a further advancing movement of the device together with a cutting edge formed on the pressure piece.

Im folgenden wird ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung anhand der Zeichnung im einzelnen beschrieben. Es zeigen:

  • Fig. 1 einen Axialschnitt der Klemmvorrichtung;
  • Fig. 2 einen Schnitt A-A der Hülse und des Druckstückes der Vorrichtung nach Fig. 1;
  • Fig. 3 eine Draufsicht auf ein Anschlußelement mit angeklemmter Kabelader;
  • Fig. 3a, 3b je eine Seitenansicht des Anschlußelementes mit angeklemmter Kabelader.
In the following an embodiment of the device according to the invention is described in detail with reference to the drawing. Show it:
  • 1 shows an axial section of the clamping device;
  • FIG. 2 shows a section AA of the sleeve and the pressure piece of the device according to FIG. 1;
  • 3 shows a plan view of a connecting element with a clamped cable core;
  • 3a, 3b each a side view of the connecting element with a clamped cable core.

Die in den Fig. 1 und 2 dargestellte Vorrichtung besteht aus einem sich stufenweise verjüngenden Stößel 1, der sich mit seinem hinteren verdickten Endteil an einer in einem Hohlraum eines Gehäuses 5 angeordneten Schraubenfeder 4 abstützt. Die vorderen und mittleren Teile des Stößels 1 sind in einer Hülse 2 längsverschiebbar geführt. Am vorderen Endteil des Stößels 1 ist ferner ein Druckstück 1a ausgebildet, das - wie aus Fig. 2 ersichtlich - einen von zwei Profilstegen 1b begrenzten schrägen Längsschlitz 1c aufweist. Das vordere Ende der mit ihrem verbreiterten rückwärtigen Teil 2 im Gehäuse 5 festgelegten Hülse 2 ragt in der in Fig. 1 dargestellten Position über die Stirnkante des Druckstückes 1a hinaus. Ferner ist in diesem vorderen Ende der Hülse eine Schneidkante 3a ausgebildet, der ein Längsschlitz 3b von größerer Länge gegenüberliegt. Diese Schneidkante 3a wirkt mit einer am Druckstück 1a bzw. an seinem Übergang zum Stößel 1 vorgesehenen Schneidkante zusammen.The device shown in FIGS. 1 and 2 consists of a gradually tapering plunger 1, which is supported with its rear thickened end part on a coil spring 4 arranged in a cavity of a housing 5. The front and middle parts of the plunger 1 are guided in a longitudinally displaceable manner in a sleeve 2. At the front end part of the plunger 1, a pressure piece 1 a is also formed which, as can be seen in FIG. 2, delimits one of two profile webs 1 b has oblique longitudinal slot 1c. The front end of the sleeve 2 fixed with its widened rear part 2 in the housing 5 protrudes beyond the end edge of the pressure piece 1 a in the position shown in FIG. 1. Furthermore, a cutting edge 3a is formed in this front end of the sleeve, which is opposite a longitudinal slot 3b of greater length. This cutting edge 3a interacts with a cutting edge provided on the pressure piece 1a or at its transition to the plunger 1.

Wie in Fig. 3 gestrichelt dargestellt, umschließt die Hülse 3 vor und während des eigentlichen Klemmvorganges ein Anschlußelement 11, das einen Z-förmigen Querschnitt aufweist. In jedem Schenkel 13 dieses Anschlußelementes 11 ist ein Längsschlitz 13a von vorbestimmter Länge vorgesehen (vgl. Fig. 3a, 3b), dessen abgerundeter Boden das Widerlager für die Isolierung der Kabelader im voll eingedrückten Zustand bildet. Der Mittelteil des Z-förmigen Anschlußelementes stellt das eigentliche Kontaktelement 12 dar und weist einen Längsschlitz 12a von größerer Länge auf, der in seinem unteren Teil 12b zur Erzielung einer Federwirkung zweier in das Drahtmaterial einschneidender Zungen 12c eine größere Breite besitzt.As shown in dashed lines in Fig. 3, the sleeve 3 encloses a connection element 11 which has a Z-shaped cross section before and during the actual clamping process. In each leg 13 of this connecting element 11 there is a longitudinal slot 13a of a predetermined length (see FIGS. 3a, 3b), the rounded bottom of which forms the abutment for the insulation of the cable core in the fully pressed-in state. The middle part of the Z-shaped connecting element represents the actual contact element 12 and has a longitudinal slot 12a of greater length, which has a greater width in its lower part 12b to achieve a spring action of two tongues 12c cutting into the wire material.

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgende:

  • Es wird eine Kabelader in die verbreiterte Maulöffnung der Schlitze 13a lose eingelegt, wie es in Fig. 3a gestrichelt dargestellt ist. Daraufhin wird die längsgeschlitzte Hülse so auf das Anschlußelement aufgesetzt, daß die beiden vorstehenden Teile der Kabelader in den Längsschlitz der Hülse hineingleiten und die Hülsenwandung bei einem Vorschub der Vorrichtung sich direkt neben die Außenflächen der Schenkel 13 des Anschlußelementes anlegen. Die Längsschlitze in der Hülse sind so gewählt, daß sich durch eine weitere Vorschubbewegung das Druckstück 1a in der in Fig. 3 dargestellten Weise auf die mittleren Teile der Kabelader abstützt und die Kabelader bis zum Boden der Schlitze 13a in das Anschlußelement hineindrückt.
The functioning of the device according to the invention is as follows:
  • A cable wire is loosely inserted into the widened mouth opening of the slots 13a, as shown in broken lines in FIG. 3a. Then the longitudinally slotted sleeve is placed on the connecting element so that the two protruding parts of the cable core in the Slide the longitudinal slot of the sleeve into it and, when the device is advanced, the sleeve wall lies directly next to the outer surfaces of the legs 13 of the connecting element. The longitudinal slots in the sleeve are selected so that the thrust piece 1a is supported by a further feed movement in the manner shown in Fig. 3 on the central parts of the cable core and presses the cable core down to the bottom of the slots 13a in the connecting element.

Eine weitere Vorschubbewegung des Gehäuses 5 bewirkt, daß sich die Hülse gegenüber dem Stößel 1 und dem Druckstück 1a weiter vorschiebt, so daß die Schneiden zur Wirkung gelangen und ein vorstehendes Ende der Kabelader in vorgegebenem Abstand quer abschneiden. Damit ist der Anschaltvorgang abgeschlossen und die Vorrichtung kann abgezogen werden.A further feed movement of the housing 5 causes the sleeve to advance further relative to the plunger 1 and the pressure piece 1a, so that the cutting edges come into effect and cut off a projecting end of the cable core transversely at a predetermined distance. This completes the connection process and the device can be removed.
