Abstract

The inventive connecting device enables two different, adjacent lying, non-bared conductors (3) to be connected while requiring little bed width. This is achieved by a cutting element (6) comprising several contact blades (7) of different heights interacting with a lever (4), whose thrust member (8) presses upon the inserted conductors (3) until the conductor wires come into contact with the contact blades (7).

Description

Beschreibungdescription
Anschlußvorrichtung für mindestens eine nicht abisolierte LeitungConnection device for at least one non-stripped line
Die Erfindung bezieht sich auf eine Anschlußvorrichtung für mindestens eine nicht abisolierte Leitung mit einem Schneidkörper, der mehrere Kontaktschneiden zum Durchschneiden der Isolierung aufweist.The invention relates to a connection device for at least one non-stripped line with a cutting body having a plurality of contact blades for cutting through the insulation.
Eine gattungsgemäße Anschlußvorrichtung ist aus der Druckschrift EP 0 511 098 Bl bekannt. Diese umfaßt ein metallisches Glied, das in einem Raum eines Gehäuses festgelegt ist und das mindestens eine Anschlußeinheit mit einer konvexen sechseckigen Form und mit einem Schlitz entlang einer seiner diagonalen Ebenen bildet. Der Schlitz dient zum Halten des Drahts und zum Durchschneiden der Isolierung, um die Leitungsader zu kontaktieren. Der Schlitz besitzt eine erweiterte Mündung zum Durchschneiden der Isolierung des Drahts mit Schneidekanten.A generic connection device is known from EP 0 511 098 B1. This comprises a metallic member which is fixed in a space of a housing and which forms at least one connection unit with a convex hexagonal shape and with a slot along one of its diagonal planes. The slot is used to hold the wire and cut through the insulation to contact the wire. The slot has an enlarged mouth for cutting through the insulation of the wire with cutting edges.
Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußvorrichtung der obengenannten Art zu schaffen, die auf einfache Weise eine Kontaktierung von Leitern unterschiedlichen Durch- messers unabhängig vom Isolationsmaterial ermöglicht und dabei für massive, fein- und mehrdrähtige Leitquerschnitte geeignet ist.The invention has for its object to provide a connecting device of the type mentioned above, which allows contacting conductors of different diameters in a simple manner, regardless of the insulation material, and is suitable for solid, fine and multi-wire conductor cross-sections.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Spitzen der Kontaktschneiden von der Leitungsachse der in die Anschlußvorrichtung eingeführten in Kontaktierungsposition befindlichen Leitung unterschiedlich weit beabstandet sind, daß die Anschlußvorrichtung ein Druckstück aufweist, das in einer Montagestellung zu den Kontaktschneiden einen Zwischen- räum mit abgestufter unterschiedlicher Öffnungsweite aufweist, so daß Leitungen mit unterschiedlichem Querschnitt in den Zwischenraum soweit einführbar sind, daß zumindest eine der Kontaktschneiden die Leitung überdeckt und daß durch Krafteinwirkung auf das Druckstück die eingeführte Leitung zumindest in eine der überdeckenden Kontaktschneiden bis zur Kontaktierung ihrer Leitungsader eindrückbar ist .The object is achieved in that the tips of the contact blades are spaced different distances from the line axis of the line inserted into the connecting device in the contacting position, that the connecting device has a pressure piece which, in an assembly position with the contact blades, has an intermediate space with different graded Has opening width so that lines with different cross-section can be inserted into the space so far that at least one the contact cutting covers the line and that the force applied to the pressure piece allows the inserted line to be pressed into at least one of the overlapping contact cutting edges until contact is made with its line core.
Vorteilhafte Weiterbildung der Erfindung sind den Unteransprüchen 2 bis 7 zu entnehmen.Advantageous developments of the invention can be found in subclaims 2 to 7.
Ist z.B. das Druckstück federbelastet, so wird dauerhaft eine gute Kontaktierung beibehalten, da durch die Federwirkung ein Nachgeben der Kontaktierungskräfte ausgeglichen wird.Is e.g. the pressure piece is spring-loaded, good contact is permanently maintained, since the spring action compensates for the yielding of the contacting forces.
Vorteilhafterweise ist das Druckstück Unterteil eines drehbar gelagerten Hebels mit auf das Druckstück wirkenden Federn. Der Hebel ist normalerweise im Gehäuse eines Schaltgeräts gelagert und somit verliersicher untergebracht. Über den Hebel läßt sich mittels eines Schraubendrehers ohne großen Kraftaufwand der zur Kontaktierung mit den Kontaktschneiden erforderliche Druck aufbringen.The pressure piece is advantageously the lower part of a rotatably mounted lever with springs acting on the pressure piece. The lever is normally stored in the housing of a switchgear and is therefore captive. The pressure required to make contact with the contact blades can be applied via the lever by means of a screwdriver without great effort.
Der Anschluß von Leitungen wird bei der vorliegenden Anschlußvorrichtung besonders dadurch erleichtert, daß der Hebel in einer Offenstellung und in einer Kontaktierstellung verrastbar ist. Zugleich ist damit die Kontaktierstellung ge- sichert.The connection of lines is particularly facilitated in the present connection device in that the lever can be locked in an open position and in a contacting position. At the same time, the contact position is secured.
Weist das Druckstück zwei durch einen Schlitz gebildete, unabhängig voneinander federnde Bereiche auf, so können hierdurch zwei nebeneinander liegende kontaktierte Leitungen ebenfalls unabhängig voneinander kontaktieren und der Kontaktzustand kann besser beibehalten werden.If the pressure piece has two areas which are formed by a slot and are resilient independently of one another, two contacted lines lying next to one another can hereby also contact independently of one another and the contact state can be better maintained.
Außerdem ist es vorteilhaft, wenn die Anschlußvorrichtung in einem Schaltgerät vorgesehen ist und der Schneidkörper zu- gleich als Schaltstück des Schaltgeräts dient. Eine besonders einfache Fertigung läßt sich erreichen, wenn der Schneidkörper aus mehreren Schneidblechen mit sägezahn- ähnlichem Profil zusammengesetzt ist.It is also advantageous if the connection device is provided in a switching device and the cutting body simultaneously serves as a switching piece of the switching device. A particularly simple manufacture can be achieved if the cutting body is composed of several cutting plates with a sawtooth-like profile.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG 1 ein Schaltgerät mit erfindungsgemäßen Profilklemmen,1 shows a switching device with profile terminals according to the invention,
FIG 2 eine Schnittansicht einer erfindungsgemäßen Profil- klemme,2 shows a sectional view of a profile clamp according to the invention,
FIG 3 ein Schaltstück der Profilklemme gemäß FIG 2,3 shows a contact piece of the profile terminal according to FIG. 2,
FIG 4 einen Hebel der Profilklemme im montierten Zustand und4 shows a lever of the profile clamp in the assembled state and
FIG 5 eine perspektivische Ansicht des Hebels gemäß FIG 4 im nichtmontierten Zustand.5 shows a perspective view of the lever according to FIG. 4 in the unmounted state.
In FIG 1 ist ein Schaltgerät 1 dargestellt, das mit erfindungsgemäßen Profilklemmen 2 zum Anschluß elektrischer Leitungen 3 ausgestattet ist. Von den Profilklemmen 2 sind hier Hebel 4 sichtbar, die zum Teil in Offenstellung, d.h. bei nichtkontaktierter Leitung 3, und zum Teil in geschlossener Stellung bei kontaktierter Leitung 3 gezeigt sind. Die Hebel 4 sind in Offenstellung und in Kontaktierungsstellung jeweils verrastbar. Mit jeder Profilklemme 2 lassen sich zwei ver- schiedenartige, nebeneinander liegende und nicht abisolierte Leitungen 3 kontaktieren. Es können massive oder feindrähtige Leitungen 3 mit unterschiedlichem Leitungsquerschnitt sein, z.B. im Bereich 0,5 bis 2,5 mm2.1 shows a switching device 1 which is equipped with profile terminals 2 according to the invention for connecting electrical lines 3. Of the profile clamps 2, levers 4 are visible here, some of which are shown in the open position, ie when the line 3 is not contacted, and some are shown in the closed position when the line 3 is contacted. The levers 4 can each be locked in the open position and in the contacting position. Each profile terminal 2 can be used to contact two different, adjacent and not stripped lines 3. Solid or finely stranded lines 3 with different line cross sections can be used, for example in the range 0.5 to 2.5 mm 2 .
FIG 2 zeigt eine Schnittdarstellung einer Profilklemme 2 in einem Gehäuse 5, z.B. eines Schaltgeräts 1. Die Profilklemme 2 besteht im wesentlichen aus einem Schneidkörper 6 mit mehreren unterschiedlich hohen Kontaktschneiden 7, der z.B. durch Schneidbleche mit sägezahnähnlichem Profil erzeugt wird. Dieser Schneidkörper 6 stellt zugleich das Schaltstück des Schaltgeräts 1 dar. Dem Schneidkörper 6 gegenüberliegend ist im Gehäuse 5 der Hebel 4 drehbar gelagert angeordnet . Bei Offenstellung des Hebels 4, wie in Figur 2 dargestellt, ist in den Zwischenraum zwischen dem Hebel 4 und dem Schneidkörper 6 eine elektrische Leitung 3 einführbar. Die Höhe der Kontaktschneiden 7 sind derart abgestuft, daß sich mit zu- nehmender Einführtiefe die Öffnungsweite zur Einführung der elektrischen Leitungen 3 zwischen den Kontaktschneiden 7 und dem Hebel 4 verkleinert. Somit lassen sich elektrische Leitungen 3 mit geringem Durchmesser weiter einführen als solche mit größerem Durchmesser, was in Figur 2 durch die beiden dargestellten Leitungen 3 mit unterschiedlichem Querschnitt angedeutet ist. Der Hebel 4 hat an seiner Unterseite ein federbelastetes Druckstück 8 als Unterteil. Beim Umschwenken des Hebels 4 in die gestrichelt dargestellte Position werden die Leitungen 3 in die Kontaktschneiden 7 gedrückt, wobei ein abgestuftes Einschneiden der Isolierung und das Kontaktieren der Leitungen 3 erfolgt. Durch das Klemmen der Isolierung wird eine sichere Zugentlastung der elektrischen Leitungen 3 erreicht .2 shows a sectional view of a profile clamp 2 in a housing 5, for example a switching device 1. The profile clamp 2 essentially consists of a cutting body 6 with a plurality of contact blades 7 of different heights, which is produced, for example, by cutting plates with a sawtooth-like profile. This cutting body 6 also represents the switching element of the switching device 1. Opposite the cutting body 6, the lever 4 is arranged rotatably in the housing 5. at In the open position of the lever 4, as shown in FIG. 2, an electrical line 3 can be inserted into the space between the lever 4 and the cutting body 6. The height of the contact blades 7 are graduated in such a way that the opening width for the introduction of the electrical lines 3 between the contact blades 7 and the lever 4 decreases with increasing insertion depth. Thus, electrical lines 3 with a small diameter can be inserted further than those with a larger diameter, which is indicated in FIG. 2 by the two lines 3 shown with different cross sections. The lever 4 has on its underside a spring-loaded pressure piece 8 as a lower part. When the lever 4 is pivoted into the position shown in dashed lines, the lines 3 are pressed into the contact blades 7, the insulation being cut in stages and the lines 3 being contacted. By clamping the insulation, a secure strain relief of the electrical lines 3 is achieved.
FIG 3 zeigt den zugleich als Schaltstück verwendeten Schneidkörper 6 mit den Kontaktschneiden 7. Dieser kann durch Schneidbleche mit sägezahnähnlichem Profil erzeugt werden. Die Schneidbleche können mit Sägezahnprofil gestanzt, paketiert und einstückig zu dem Schaltstück verbunden werden. Der Stromfluß erfolgt bei dieser Ausführungsform direkt vom Leiter auf das Schaltstück. Die Höhe der Kontaktschneiden 7 steigt von dem als Einführseite dienenden Ende aus an, um für nicht abisolierte Leitungen 3 unterschiedlichen Durchmessers entsprechend angepaßte Öffnungsweiten zu erreichen.3 shows the cutting body 6, which is also used as a switching piece, with the contact blades 7. This can be produced by cutting plates with a sawtooth-like profile. The cutting plates can be punched with a sawtooth profile, packaged and connected in one piece to the contact piece. In this embodiment, the current flows directly from the conductor to the contact piece. The height of the contact blades 7 increases from the end serving as the insertion side in order to achieve appropriately adapted opening widths for non-stripped lines 3 of different diameters.
FIG 4 und 5 zeigen den Hebel 4 mit dem Druckstück 8. Der Hebel 4 ist über ein Drehlager im Gehäuse 5 eines Schaltgeräts 1 schwenkbar. Er besteht im wesentlichen aus einem Oberteil, in dem zwei Federn 9 gelagert sind, die auf das Druck- stück 8 mit abgerundeter Außenfläche einwirken. Dieses Unterteil ist zwar einstückig aufgebaut, weist aber durch Ausbildung mit einem Schlitz 10 zwei voneinander unabhängig federn- de Bereiche 12 auf, auf die jeweils eine der Federn 9 drückt. Ober diese Bereiche werden die zwei kontaktierten elektrischen Leitungen 3 gemäß FIG 2 federbelastet auf die Kontaktschneiden 7 gedrückt. Ein eventuelles Nachgeben bzw. Nachset- zen der Kontaktierkräfte wird durch die Federwirkung ausgeglichen. Durch diese Ausführung wird erreicht, daß die Kontaktierung für längere Betriebsdauern, wie sie bei Schaltgeräten üblich sind, unverändert erhalten bleibt. Der Hebel 4 ist mit einer Ausnehmung 11 versehen, über die mittels eines Schraubendrehers eine einfache Betätigung möglich ist (siehe FIG 1) . Durch unterschiedliche Farbgebung der Hebel 4 können die Anschlußstellen entsprechend gekennzeichnet werden.4 and 5 show the lever 4 with the pressure piece 8. The lever 4 can be pivoted via a pivot bearing in the housing 5 of a switching device 1. It essentially consists of an upper part in which two springs 9 are mounted, which act on the pressure piece 8 with a rounded outer surface. Although this lower part is constructed in one piece, it has two springs which are independent of one another due to the formation with a slot 10. de areas 12 on which one of the springs 9 presses. The two contacted electrical lines 3 are pressed spring-loaded onto the contact blades 7 over these areas. Any resilience or resetting of the contacting forces is compensated for by the spring action. This design ensures that the contact remains unchanged for longer operating times, as are common in switching devices. The lever 4 is provided with a recess 11, via which simple actuation is possible by means of a screwdriver (see FIG. 1). The connection points can be marked accordingly by different coloring of the lever 4.
Der für den Anschluß eines Leiters erforderliche Platzauf- wand, insbesondere die sogenannte Bettbreite, ist bei der Profilklemme im wesentlichen durch den Leiter selbst bestimmt. Im Vergleich hierzu ist beim Schraubanschluß die Bettbreite wenigstens um den Durchmesser der Anschlußschrauben größer.The space required for the connection of a conductor, in particular the so-called bed width, is essentially determined by the conductor itself in the profile terminal. In comparison, the bed width of the screw connection is at least larger by the diameter of the connection screws.
