Description
Die Erfindung betrifft eine Reihenklemme mit einem Isolierstoffgehäuse und einer Anschlußvorrichtung für einen isolierten Leiter, der ohne Abisolierung zwischen einer Schneide und einer Gegenauflage nachfedernd geklemmt wird. Diese Anschlußtechnik vereinfacht und beschleunigt die Arbeit, was insbesondere bei Schaltanlagen und Maschinen mit hohem Verdrahtungsumfang und meterlangen Anschlußleisten zu Buche schlägt.The invention relates to a terminal block with a Isolierstoffgehäuse and a connection device for one insulated conductor without stripping between one Cutting edge and a counter support is clamped. This connection technology simplifies and speeds up Work what with switchgear and machines in particular high wiring volume and meter-long terminal strips Beech beats.
Bekannt sind abisolierungsfreie Klemmen, beispielsweise nach FR-A-2 503 464, die als wesentliches Anschlußelement eine Schneidbuchse oder dergleichen aufweisen. Typisch sind dabei zwei sich gegenüberstehende Schneiden, die zwischen sich einen Schlitz bilden. In diesen Schlitz, der gegebenenfalls zum Einsteckende hin breiter wird, wird der Leiter in Richtung der Schneiden hineingezwängt. Dabei führt der Leiter eine Bewegung senkrecht zu seiner Längserstreckung aus. Der Isoliermantel wird von den Schneiden in einem ziehenden Schnitt durchdrungen, bis die Kupferseele mit den Schneiden in Berührung kommt. Gegebenenfalls dringen die Schneiden teilweise auch noch in den Kupferwerkstoff ein.Stripping-free terminals are known, for example according to FR-A-2 503 464, which is an essential connecting element Have cutting bushing or the like. Are typical two opposing cutting edges, between themselves form a slit. In this slot, if necessary becomes wider towards the insertion end, the conductor in Squeezed in the direction of the cutting edges. The leader leads a movement perpendicular to its longitudinal extent. The Insulating jacket is pulled from the cutting edges in one Cut penetrated until the copper core with the cutting edges comes into contact. If necessary, the cutting edges penetrate partly also in the copper material.
Bei Reihenklemmen ist die Breite in Anreihrichtung ein wirtschaftlich wichtiges Kriterium. Der untere Grenzwert dieser Breite ist die Summe aus dem Außendurchmesser des isolierten Leiters und der Dicke der Wand des Isolierstoffgehäuses, die zwei Reihenklemmen voneinander trennt. Die Dicke der Schneidbuchse der bekannten abisolierungsfreien Klemme übersteigt notwendigerweise den Durchmesser der isolierten Leiters beträchtlich. Man muß von einer Schlitzbreite ausgehen, die örtlich nahezu gleich dem Leiterdurchmesser ist. Hinzukommt die Breite der beiden Schneiden und eventuell deren abgekantete Partien, so daß sich insgesamt eine relativ breite Reihenklemme ergibt.In the case of terminal blocks, the width is in the baying direction economically important criterion. The lower limit this width is the sum of the outside diameter of the insulated conductor and the thickness of the wall of the Isolierstoffgehäuses, the two terminal blocks from each other separates. The thickness of the cutting sleeve of the known Stripping-free terminal necessarily exceeds that The diameter of the insulated conductor is considerable. You have to go from a slot width that is almost the same locally Conductor diameter is. Then there is the width of the two Cut and possibly their folded parts, so that overall there is a relatively wide terminal block.
In der deutschen Offenlegungsschrift DE 31 22 303 A1 wird eine Federklemme zum Anschluss eines isolierten elektrischen Leiters an einer Klemmleiste offenbart.In the German patent application DE 31 22 303 A1 a spring clip for connecting an insulated electrical Conductor disclosed on a terminal block.
Die Federklemme umfasat einen festgelegten und einen federnd bewegbaren Schenkel in der Klemmeinrichtung mit im Querschnitt keilförmigen und mittig eingekerbten Schneidklemmkanten, wobei die Endabschnitte der Schenkel zueinander mit einem spitzen Winkel kreuzend angeordnet sind. The spring clip includes a fixed and a spring movable leg in the clamping device with in Cross-section wedge-shaped and notched in the center IDC edges, the end portions of the legs are arranged crossing each other at an acute angle.
Die Federklemme weist dabei eine Breite auf, die deutlich größer ist als der Durchmesser des größten dafür vorgesehenen Leiters.The spring clip has a width that is clear is larger than the diameter of the largest intended Conductor.
Der Erfindung liegt die Aufgabe zugrunde, diesen prinzipiellen Nachteil zu vermeiden und eine Reihenklemme der einleitend bezeichneten Art vorzuschlagen, deren Handhabung und konstruktive Gestaltung einfach ist und die gleichzeitig eine geringe Breite in Anreihrichtung hat.The invention is based on the object basic disadvantage to avoid and a terminal block to propose the type described in the introduction, its handling and constructive design is simple and at the same time has a narrow width in the baying direction.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst, wobei der Grundgedanke darin besteht, daß der Leiter wie mit einer Beißzange gefaßt wird. Die Schneiden erstrecken sich in Anreihrichtung und der Leiter wird senkrecht zu den Schneiden zwischen diese eingeführt, wobei er sich in Richtung seiner Längserstreckung bewegt. Die Länge der Schneiden braucht somit grundsätzlich nicht größer als der Durchmesser des Leiters zu sein. Alle anderen konstruktiven Teile können diesem Maß, das gleichzeitig die Tiefe des Isoliergehäuses ist, untergeordnet werden.This object is achieved by the characterizing Features of claim 1 solved, the basic idea therein there is that the head is gripped like a pair of pliers. The cutting edges extend in the row and the The conductor becomes perpendicular to the cutting edge between these introduced, moving in the direction of its longitudinal extent emotional. The length of the cutting edges therefore basically needs not to be larger than the diameter of the conductor. All other structural parts can measure that at the same time the depth of the insulating housing is subordinate become.
Obwohl es funktionell ausreichend sein mag, den Leiter zwischen einer Schneide, welche durch die Isolierung dringt, und einer nicht schneidfähigen Gegenauflage zu fassen, wird eine Gegenauflage bevorzugt, die ebenfalls eine Schneide ist, wobei beide Schneiden beißzangenartig ohne Seitenversatz gegeneinander bewegbar sind. Although it may be functionally sufficient, the leader between a cutting edge that penetrates the insulation, and a non-cuttable counter support preferred a counter support, which is also a cutting edge, where both cutting pliers-like without side offset are movable against each other.
Nach einer weiteren vorteilhaften Ausführungsform umfaßt die Anschlußvorrichtung eine querschnittlich C-förmige einstückige Beißhülse aus einem federnden Werkstoff, deren einander zugewandte Abkantungen als Schneiden ausgebildet sind. Da diese Schneiden normalerweise spiegelsymmetrisch geformt und angeordnet sind und aus demselben Werkstoff bestehen, wird erreicht, daß beide Schneiden in den Isolierstoffmantel des Leiters eindringen und den Kontakt mit der Leiterseele herstellen.According to a further advantageous embodiment, the Connection device a cross-sectionally C-shaped one-piece bite sleeve made of a resilient material, the mutually facing bevels formed as cutting edges are. Because these cutting edges are usually mirror-symmetrical are shaped and arranged and made of the same material exist, it is achieved that both cutting edges in the Insulating jacket of the conductor penetrate and contact with of the leader soul.
Nach einer ersten Alternative dieser Ausführungsform federn die Zangenschenkel der Beißhülse auseinander, d. h. sie bilden im entspannten Zustand einen Schlitz, der so groß ist, daß der isolierte Leiter eingeführt werden kann. Um den Kontakt herzustellen, werden die Zangenschenkel mittels einer Schraube oder eines Exzenters gegeneinander gedrückt, so daß die Zangenschenkel dann auf die Schneiden eine Federkraft in Klemmrichtung ausüben.Spring according to a first alternative of this embodiment the jaws of the bite sleeve apart, d. H. she form a slot in the relaxed state that is so large that the insulated conductor can be inserted. To the To make contact, the pliers legs are made using a Screw or an eccentric pressed against each other, so that the pliers legs then spring into the cutting edges Exercise the clamping direction.
Die andere Alternative besteht darin, daß die Zangenschenkel der Beißhülse zusammenfedern, d. h. von sich aus die Kraft zum Durchtrennen des Isolierstoffmantels aufbringen. In diesem Fall sind Mittel zum Öffnen der Zangenschenkel vorzusehen, um den Leiter einstecken zu können. In Betracht kommt z. B. eine Exzenternuß, die in der Beißhülse angeordnet ist und diese aufweitet. Eine andere Möglichkeit besteht darin, an einem der Zangenschenkel eine taschenartige Anformung vorzusehen, in welche ein Aufbiegewerkzeug eingesteckt werden kann, z. B. ein Schraubendreher, der eine Verlängerung des Zangenschenkels bildet. The other alternative is that the pliers legs spring the bite sleeve together, d. H. inherently the power Apply to cut through the insulation jacket. In In this case, means for opening the pliers legs to be provided in order to be able to insert the conductor. In consideration comes z. B. an eccentric nut, which is arranged in the bite sleeve and expands it. Another option is there inside, a pocket-like on one of the pliers legs Provide formation in which a bending tool can be inserted, e.g. B. a screwdriver, the one Extension of the pliers leg forms.
Eine vorteilhafte Abwandlung der Beißhülse entsteht dadurch, daß die Anschlußvorrichtimg eine querschnittlich im Wesentlichen C-förmige Zangenanordnung aufweist, deren Zangenschenkel beschränkt gelenkig ineinandergefügt sind und einander zugewandte Abkantungen aufweisen, die als Schneiden ausgeführt sind, wobei ein Zangenschenkel Bestandteil einer Stromschiene oder eines Metallgehäuses ist und damit eine Fixierung im Isolierstoffgehäuse erfährt und der andere Zangenschenkel beweglich ist.An advantageous modification of the bite sleeve results from that the connecting device a cross-section in Has essentially C-shaped pliers arrangement, the Pliers legs are limitedly articulated and have mutually facing bends, which are called cutting are executed, a pliers leg part of a Busbar or a metal housing and is therefore a Experienced in the insulating housing and the other Pliers leg is movable.
Zweckmäßigerweise kann aber auch wenigstens einer der beiden Zangenschenkel aus einem Federwerkstoff bestehen. In diesem Fall ist es möglich, die Zangenschenkel mit Hilfe eines Exzenters, einer Schraube oder dergleichen zusammenzudrücken, um so die nötige Schneid- und Klemmkraft zu erzeugen.Expediently, however, at least one of the two can also be used Pliers legs consist of a spring material. In this It is possible to use a pliers leg Eccentric, a screw or the like, to generate the necessary cutting and clamping force.
Als weitere Verbesserung dieser Ausführungsform, insbesondere wenn der Zangenschenkel mittels eines Exzenters oder eines Klemmhebels betätigt wird, wird vorgeschlagen, daß der bewegliche Zangenschenkel seitlich geführt ist und die Führung dem Zangenschenkel zugewandte Rastvorsprünge aufweist, die beim Betätigen des Exzenters oder dergleichen zurückweichen und den Zangenschenkel in der Klemmstellung fixieren. Man braucht also bei einer solchen Anschlußvorrichtung lediglich den nicht abisolierten Leiter einzustecken und den Betätigungshebel umzulegen, der dann in dieser Stellung verbleibt. As a further improvement of this embodiment, in particular if the pliers leg by means of an eccentric or a Clamping lever is operated, it is proposed that the movable pliers legs is guided laterally and the Guide the locking projections facing the pliers leg has when actuating the eccentric or the like back away and the pliers leg in the clamped position fix. So you need one Connection device only the non-stripped conductor to insert and flip the operating lever, which then in this position remains.
Schließlich werden noch besonders vorteilhafte Ausbildungen speziell der Schneiden vorgeschlagen, die bei den beschriebenen Klemmen den Kraftbedarf für einen sicheren Leiteranschluß herabsetzen. Es wurde schon erwähnt, daß die Breite der Schneiden nicht größer als der Außendurchmesser des dicksten vorgesehenen Leiters sein muß. Damit ist ein realisierbarer Maximalwert für die Breite der übrigen konstruktiven Teile der Klemme vorgegeben. Um aber einen guten Kontakt zu schaffen, braucht der Isolierstoffmantel nicht wie mit einem Messer über seinen ganzen Durchmesser aufgeschnitten zu werden, sondern es genügt, wenn die Länge der Schneiden kleiner als der Durchmesser des Isoliermantels des anzuschließenden Leiters ist. Eine solche kurze Schneide findet beim radialen Durchstoßen des Isoliermantels einen geringeren Widerstand. Sie muß nur die Leiterseele auch sicher treffen. Praktisch wird es also genügen, wenn die Länge der Schneide etwa dem Durchmesser der Leiterseele entspricht. Da der Zangenschenkel im übrigen breiter ist, stellt sich die einzelne Schneide als vorstehender Zahn am Zangenschenkel dar, dessen zur Schneide senkrechte Länge wenigstens gleich der radialen Dicke des Isoliermantels sein muß. Der Zahn soll ja unbehindert eindringen könne.Finally, there are particularly advantageous training courses specifically the cutting suggested at the described clamps the power requirement for a safe Lower conductor connection. It has already been mentioned that the The width of the cutting edges is not greater than the outside diameter of the thickest conductor provided. So that's a realizable maximum value for the width of the others constructive parts of the clamp. But one The insulation jacket needs to make good contact not like a knife across its entire diameter to be cut open, but it suffices if the length the cutting is smaller than the diameter of the insulating jacket of the conductor to be connected. Such a short cutting edge finds one when the insulating jacket is pierced radially less resistance. You just need the ladder soul too meet safely. In practice, it will suffice if the Length of the cutting edge approximately the diameter of the conductor core equivalent. Since the pliers leg is wider, the individual cutting edge turns into a protruding tooth Pliers legs, the length of which is perpendicular to the cutting edge be at least equal to the radial thickness of the insulating jacket got to. The tooth should be able to penetrate unhindered.
