SchneidklemmeinrichtungPiercing means
Die vorliegende Erfindung betrifft eine Schneidklemmeinrichtung mit einem Grundkörper, einer im Grundkörper gehaltenen Schneidklemme und einem vom Grundkörper geführten Schließelement, das zumindest von einer Öffnungs- in eine Schließstellung überführbar ist, wobei in der Öffnungsstellung ein Lei- ter in das Schließelement einführbar ist und ein in das Schließelement eingeführter Leiter durch Überführen des Schließelements in die Schließstellung in die Schneidklemme einführbar und von der Schneidklemme haltbar und klemmbar ist, wobei die Schneidklemme von einer Überfeder umgriffen ist, die die Schneidklemme mit Kontaktstücken kontaktiert und so eine Andruckkraft auf die Schneidklemme ausübt.The present invention relates to an insulation displacement device with a base body, an insulation displacement clamp held in the base body and a closing element guided by the base body, which can be moved at least from an open position into a closed position, a conductor being insertable into the closed element and an in the closing element of the inserted conductor can be inserted into the insulation displacement terminal by moving the locking element into the closed position and can be held and clamped by the insulation displacement terminal, the insulation displacement clamp being encompassed by an over-spring which contacts the insulation displacement terminal with contact pieces and thus exerts a pressing force on the insulation displacement terminal.
Eine derartige Schneidklemmeinrichtung ist beispielsweise aus der DE 197 32 182 Cl bekannt. Bei ihr ist die Überfeder starr mit der Schneidklemme" verbunden.Such an insulation displacement device is known for example from DE 197 32 182 Cl. With her the spring is rigidly connected to the insulation displacement " .
Die Aufgabe der vorliegenden Erfindung besteht darin, eine verbesserte Schneidklemmeinrichtung zu schaffen.The object of the present invention is to provide an improved insulation displacement device.
Die Aufgabe wird dadurch gelöst, dass die Überfeder an dem Schließelement angeordnet ist, so dass die Kontaktstücke die Schneidklemme in der Öffnungsstellung in Öffnungskontaktbereichen und in der Schließstellung in Schließkontaktbereichen kontaktieren.The object is achieved in that the spring is arranged on the closing element, so that the contact pieces contact the insulation displacement contact in the open position in the open contact areas and in the closed position in the closed contact areas.
Denn dadurch ist eine Variation des Einwirkens der Überfeder auf die Schneidklemme möglich.This makes it possible to vary the action of the over-spring on the insulation displacement terminal.
Wenn das Schließelement und die Überfeder einstückig mitein- ander verbunden sind, ist die Schneidklemmeinrichtung besonders einfach aufgebaut. Wenn das Schließelement und die Überfeder als Stanz-Biege- Teil ausgebildet sind, ist die Herstellung von Schließelement und Überfeder besonders einfach.If the closing element and the spring are connected to one another in one piece, the insulation displacement device is of particularly simple construction. If the closing element and the spring are designed as a stamped and bent part, the production of the closing element and spring is particularly simple.
Die Betätigung des Schließelements ist besonders leicht möglich, wenn an das Schließelement ein Lagerelement für ein Betätigungswerkzeug angeformt ist. Vorzugsweise ist dabei auch das Lagerelement Bestandteil des Stanz-Biege-Teils .The actuation of the closing element is particularly easy if a bearing element for an actuating tool is molded onto the closing element. The bearing element is preferably also part of the stamped and bent part.
Wenn die Schneidklemme zwischen den Öffnungskontaktbereichen und den Schließkontaktbereichen derart ausgebildet ist, dass die Andruckkraft beim Überführen des Schließelements von der Offnungs- in die Schließstellung variiert, ist die Kraftausübung auf die Schneidklemme an die jeweilige Position des Schließelements zwischen der Offnungs- und der Schließstellung anpassbar.If the insulation displacement between the opening contact areas and the closing contact areas is designed such that the pressure force when the closing element is transferred from the open to the closed position, the force exerted on the insulation displacement clamp can be adapted to the respective position of the closing element between the open and the closed position.
Wenn die Schneidklemme in den Offnungs- und/oder den Schließkontaktbereichen und die Kontaktstücke derart ausgebildet sind, dass die Andruckkraft in der Offnungs- und/oder der Schließstellung minimal ist, bilden die Offnungs- und/oder die Schließstellung Vorzugsstellungen. Ihr Erreichen ist somit taktil erfassbar. Die Minimierung der Andruckkraft kann beispielsweise dadurch erreicht werden, dass die Schneidklem- me in den Offnungs- und/oder den Schließkontaktbereichen geschwungen verjüngt ist. Vorzugsweise sind die Kontaktstücke hiermit korrespondierend verjüngt.If the insulation displacement device in the opening and / or the closing contact areas and the contact pieces are designed such that the pressing force in the opening and / or the closed position is minimal, the open and / or the closed position form preferred positions. The fact that they have been reached can thus be detected tactilely. The contact pressure can be minimized, for example, by the insulation displacement in the opening and / or the closing contact areas being tapered. The contact pieces are preferably correspondingly tapered.

Dabei zeigen in PrinzipdarstellungFurther advantages and details emerge from the following description of an exemplary embodiment in conjunction with the drawings. Show in principle
FIG 1 eine Schneidklemmeinrichtung mit Schließelement, Leiter und Bedienwerkzeug und FIG 2 eine Schneidklemme mit einem Schließelement. Gemäß FIG 1 weist eine Schneidklemmeinrichtung einen Grundkörper 1 auf. Im Grundkörper 1 ist eine Schneidklemme 2 gehalten. Die Schneidklemmeinrichtung weist ferner ein Schließelement 3 auf. Das Schließelement 3 ist dabei in FIG 1 und 2 in einer Öffnungsstellung dargestellt. In der Öffnungsstellung ist in das Schließelement 3 ein einadriger Leiter 4 einführbar, der nicht abisoliert sein uss .1 shows an insulation displacement device with a closing element, conductor and operating tool and FIG. 2 shows an insulation displacement device with a closing element. According to FIG. 1, an insulation displacement device has a base body 1. An insulation displacement clamp 2 is held in the base body 1. The insulation displacement device also has a closing element 3. The closing element 3 is shown in FIGS. 1 and 2 in an open position. In the open position, a single-core conductor 4 can be inserted into the closing element 3 and must not be stripped.
Das Schließelement 3 ist von der Offnungs- in eine Schließ- Stellung überführbar. Hierzu wird ein Betätigungswerkzeug 5, in der Regel ein üblicher Schraubendreher, in ein Lagerelement 6 eingeführt, das an das Schließelement 3 angeformt ist. Durch Verschwenken des Betätigungswerkzeugs 5 in einer Betätigungsrichtung A wird dann das Schließelement 3 in die Schließstellung überführt. Der Leiter 4 wird hierdurch in die Schneidklemme 2 eingeführt und in der Schließstellung von dieser gehalten und geklemmt. Die Position des Leiters 4 in der Schließstellung ist in FIG 2 dabei durch einen gestrichelt angedeuteten Kreis symbolisiert.The closing element 3 can be moved from the open position into a closed position. For this purpose, an actuating tool 5, usually a conventional screwdriver, is inserted into a bearing element 6, which is molded onto the closing element 3. By pivoting the actuating tool 5 in an actuating direction A, the closing element 3 is then moved into the closed position. The conductor 4 is hereby inserted into the insulation displacement clamp 2 and held and clamped by the latter in the closed position. The position of the conductor 4 in the closed position is symbolized in FIG. 2 by a dashed circle.
An dem Schließelement 3 ist eine Überfeder 7 angeordnet, welche die Schneidklemme 2 umgreift. Die Überfeder 7 kontaktiert dabei die Schneidklemme 2 mit Kontaktstücken 8 und übt daher eine Andruckkraft F auf die Schneidklemme 2 aus. Aufgrund der Ausbildung der Überfeder 7, insbesondere aufgrund des Vorhandenseins von vorderen Umgriffslappen 9 und hinteren Umgriffs- lappen 10, bildet die Überfeder 7 dabei gleichzeitig ein Führungselement, aufgrund dessen das Schließelement 3 bezüglich der Schneidklemme 2 und damit im Ergebnis auch im Grundkörper 1 geführt wird.An over-spring 7 is arranged on the closing element 3, which engages around the insulation displacement clamp 2. The spring 7 contacts the insulation displacement clamp 2 with contact pieces 8 and therefore exerts a pressing force F on the insulation displacement clamp 2. Due to the design of the over-spring 7, in particular due to the presence of front wrap-around flaps 9 and rear wrap-around flaps 10, the over-spring 7 simultaneously forms a guide element, on the basis of which the closing element 3 is guided in the base body 1 with respect to the insulation displacement clamp 2 and thus as a result ,
Aufgrund der Anordnung der Über eder 7 am Schließelement 3 wird die Überfeder 7 zusammen mit dem Schließelement 3 bewegt. In der Öffnungsstellung des Schließelements 3 kontak- tieren die Kontaktstücke 8 daher die Schneidklemme in Öffnungskontaktbereichen 11, in der Schließstellung in Schließkontaktbereichen 12. Ersichtlich sind dabei das Schließele- ment 3 und die Überfeder 7 einstückig miteinander verbunden. Insbesondere sind das Schließelement 3 , das Lagerelement 6 und die Überfeder 7 als (einheitliches) Stanz-Biege-Teil ausgebildet .Due to the arrangement of the spring 7 on the closing element 3, the spring 7 is moved together with the closing element 3. In the open position of the closing element 3, the contact pieces 8 therefore contact the insulation displacement contact in the open contact areas 11, in the closed position in the closed contact areas 12. The closing element can be seen here. ment 3 and the spring 7 connected in one piece. In particular, the closing element 3, the bearing element 6 and the spring 7 are designed as a (uniform) stamped and bent part.
Gemäß FIG 2 ist die Schneidklemme 2 in den Offnungs- und den Schließkontaktbereichen 11, 12 geschwungen verjüngt. Hiermit korrespondierend sind auch die Kontaktstücke 8 geschwungen verjüngt. Durch diese Ausbildung der Schneidklemme 2 und der Überfeder 7 wird erreicht, dass die Andruckkraft F in diesen beiden Stellungen minimal ist. Es werden also Vorzugsstellungen erzeugt, deren Erreichen taktil erfassbar ist.According to FIG. 2, the insulation displacement connection 2 is tapered in a curved manner in the opening and the closing contact regions 11, 12. Correspondingly, the contact pieces 8 are also tapered in a curved manner. This configuration of the insulation displacement clamp 2 and the spring 7 ensures that the pressure force F is minimal in these two positions. Preferential positions are thus generated, the attainment of which can be tactile detected.
Zwischen der Offnungs- und der Schließstellung ist die Schneidklemme 2 hingegen bauchig verbreitert . Dadurch wird die Andruckkraft F beim Überführen des Schließelements 3 von der Offnungs- in die Schließstellung gemäß dem bauchigen Verlauf der Schneidklemme 2 variiert.On the other hand, the insulation displacement clamp 2 is widened with a bulge between the open and the closed position. As a result, the pressing force F is varied when the closing element 3 is transferred from the open position into the closed position in accordance with the bulbous profile of the insulation displacement clamp 2.
Mit der erfindungsgemäßen Schneidklemmeinrichtung ist eineWith the insulation displacement device according to the invention
Reihe von Vorteilen erzielbar. Insbesondere ist die Andruckkraft F an die einzelnen Prozessschritte beim Überführen von der Offnungs- in die Schließstellung (zuerst Einführen und Isolationsdurchtrennung, dann Kontaktierung des Leiters 4) anpassbar und veränderbar. Es ist also eine an die einzelnen Prozessschritte optimierte Kraftkennlinie realisierbar, welche eine ergonomisch günstige Betätigung ermöglicht. Das Erreichen der beiden Endstellungen des Schließelements 3 ist dabei durch die Minimierung der Andruckkraft F in diesen bei- den Stellungen zum einen sicher zu bewirken und zum anderen taktil erfassbar. Im Ergebnis können sowohl die Betätigungskräfte als auch die Verfahrwege verringert werden. Es ergibt sich also ein relativ kleines Bauvolumen der Schneidklemmeinrichtung. Schließlich ist die erfindungsgemäße Schneidklemm- einrichtung auch in einem größeren Querschnittsbereich als vergleichbare Schneidklemmeinrichtung des Standes der Technik einsetzbar. A number of advantages can be achieved. In particular, the contact pressure F can be adapted and changed to the individual process steps during the transfer from the open to the closed position (first insertion and insulation separation, then contacting the conductor 4). It is therefore possible to implement a force characteristic curve optimized for the individual process steps, which enables ergonomically favorable actuation. Reaching the two end positions of the closing element 3 can be reliably effected on the one hand by minimizing the pressing force F in these two positions and, on the other hand, can be detected tactilely. As a result, both the operating forces and the travel distances can be reduced. This results in a relatively small overall volume of the insulation displacement device. Finally, the insulation displacement device according to the invention can also be used in a larger cross-sectional area than comparable insulation displacement device of the prior art.
