Description

Die Erfindung betrifft eine Schraubklemme zum Anschließen elektrischer Leiter, dessen Klemmkörper aus einem U-förmigen Blechteil besteht, zwischen dessen Schenkeln eine quer dazu angeordnete Mutter zur Aufnahme und Führung der Klemmschraube vorgesehen und vorzugsweise mittels seitlich abragender, in Ausnehmungen der Schenkel eingreifender Schultern gehalten ist. Derartige Schraubklemmen sind in vielen Varianten aus Literatur (z.B. DE-AS 19 42 982) und Praxis bekannt. Alle diese Ausführungen sind ausschließlich als Buchsenklemmen verwendet, bei denen die Klemmung eines Leiters zwischen dem Bodenabschnitt des U-förmigen 6lechteils und der Klemmschraube selbst oder einem an dieser angebrachten besonderen Klemmkörper erfolgt. Angesichts dieser beschränkten Verwendungsmöglichkeit ist der Herstellungsaufwand und Platzbedarf solcher Klemmen unangemessen hoch.The invention relates to a screw terminal for connecting electrical conductors, the clamping body of which consists of a U-shaped sheet metal part, between the legs of which a transverse nut is provided for receiving and guiding the clamping screw and is preferably held by means of laterally projecting shoulders which engage in recesses in the legs. Such screw terminals are known in many variants from literature (e.g. DE-AS 19 42 982) and practice. All of these designs are used exclusively as socket clamps, in which a conductor is clamped between the bottom section of the U-shaped 6-piece part and the clamping screw itself or a special clamping body attached to it. In view of this limited use, the manufacturing effort and space requirements of such clamps are inappropriately high.

Aufgabe der Erfindung war es deshalb, ausgehend von dem bestehenden grundsätzlichen Aufbau der Klemme und ihren Abmessungen auf möglichst einfache und kostensparende Weise die Nutzungsmöglichkeiten von Schraubklemmen nach dem Oberbegriff des Anspruches 1 zu vergrößern.It was therefore the object of the invention, based on the existing basic structure of the terminal and its dimensions, to increase the possible uses of screw terminals according to the preamble of claim 1 in a simple and cost-saving manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dan die beiden Schenkel des U-förmigen Blechteils ungleich lang sind und daß das überstehende Endteil des längeren Schenkels eine Bohrung zum Durchführen des Gewindeteils der Klemmschraube aufweist und derart quer zur Achsrichtung der Klemmschraube abgebogen ist, daB es auf der Stirnfläche des kürzeren Schenkels aufliegt.This object is achieved in that the two legs of the U-shaped sheet metal part are of unequal length and that the protruding end part of the longer leg has a bore for passing the threaded part of the clamping screw and is bent transversely to the axial direction of the clamping screw so that it is on the Face of the shorter leg rests.

Dadurch ist mit einfachsten Mitteln ohne Mehraufwand in Herstellung und Montage eine Schraubklemme der eingangs genannten Art geschaffen, die nicht nur als Buchsenklemme einsetzbar ist, sondern durch die stabile Auflagefläche des quer zur Schraubenachse liegenden Schenkelteils auch für Schraubenkopfklemmung von Leitern, insbesondere von Kabelschuhen bzw. - ösen geeignet ist. Dabei sind die Außenabmessungen gegenüber den bekannten Klemmen gleich geblieben, sodaß kein größerer Platzbedarf nötig ist und insbesondere die erfindungsgemäßen Klemmen mit den bekannten Klemmen hinsichtlich des Einsatzes in Kammern bereits vorhandener Isoliergehäuse (z.B. von Steckverbindern) kompatibel sind.As a result, a screw terminal of the type mentioned at the outset is created with the simplest means without additional effort in manufacture and assembly, which can not only be used as a socket terminal, but also for screw head clamping of conductors, in particular cable lugs or - due to the stable contact surface of the leg part lying transversely to the screw axis. is suitable. The external dimensions have remained the same compared to the known terminals, so that no larger space is required and in particular the terminals according to the invention are compatible with the known terminals with regard to use in chambers of already existing insulating housings (e.g. of connectors).

In den Unteransprüchen sind vorteilhafte Ausgestaltungen des Gegenstandes des Patentanspruches 1 beschrieben.Advantageous embodiments of the subject matter of claim 1 are described in the subclaims.

Bei einer Schraubklemme nach Anspruch 2 ist die seitliche Auflage für eine Schraubenkopfklemmung auch dann noch grofß genug, wenn im Hinblick auf eine gute Buchsenklemmung ohne separaten Klemmkörper ein Schraubenschaft mit grobem Durchmesser gewählt ist. Dabei ist ohne Vergrößerung des Platzbedarfs der Klemme eine optimal große Klemmfläche erreicht, wenn gemäß Anspruch 3 die Länge des querliegenden Endteils dem Durchmesser des Schraubenkopfes entspricht.In a screw clamp according to claim 2, the lateral support for a screw head clamping is still large enough if a screw shaft with a large diameter is selected with a view to good socket clamping without a separate clamping body. An optimally large clamping area is achieved without increasing the space requirement of the clamp if, according to claim 3, the length of the transverse end part corresponds to the diameter of the screw head.

Eine Ausgestaltung der erfindungsgemäßen Schraubklemme nach Anspruch 4 gewährleistet eine zuverlässige, von den Ab - messungen des querliegenden Endteils bzw. des Schrauben - kopfes weitgehend unabhängige Klemmung nicht nur für Kabelschuhe und - ösen, sondern auch für Drähte und Litzen. Vor allem aber ist die Gefahr einer Verletzung oder gar eines Abscherens der zu klemmenden Leiter beim Drehen des Schraubenkopfes sicher vermieden.An embodiment of the screw terminal according to the invention ensures reliable clamping, which is largely independent of the dimensions of the transverse end part or the screw head, not only for cable lugs and eyelets, but also for wires and strands. Above all, however, the risk of injury or even shearing off of the conductor to be clamped when the screw head is turned is reliably avoided.

Durch eine Ausbildung der Schraubklemme gemäß Anspruch 5 ist eine ebenso zweckmäßige wie kostengünstige Befestigungsmöglichkeit in Isoliergehäusen gegeben.By designing the screw terminal according to claim 5, there is an expedient as well as inexpensive fastening possibility in insulating housings.

Eine Ausführung nach Anspruch 6 bietet den VortEil einer Einfachen, preisgünstigen und dennoch wirkungsvollen Schraubsicherung, die überdies ohne verlierbare Teile auskommt.An embodiment according to claim 6 offers the advantage of a simple, inexpensive, yet effective screw lock, which moreover does not need any parts that can be lost.

Bei Verwendung der erfindungsgemäßen SchraubklemmE zum Anschluß von Leitungen an Kontaktteile von StEckvErbindern ist eine Ausgestaltung nach Anspruch 7 besonders vorteilhaft, weil dadurch keine besonderen Maßnahmen und Bauteile zur Verbindung von Klemmen und Kontaktteilen nötig sind.When using the screw terminal according to the invention for connecting lines to contact parts of plug connectors, an embodiment according to claim 7 is particularly advantageous because it does not require any special measures and components for connecting terminals and contact parts.

Die Figuren zeigen ein Ausführungsbeispiel der erfindungsgemäßen Schraubklemme, eingesetzt in dem IsoliertEil einer dreipoligen Steckbuchse.The figures show an embodiment of the screw terminal according to the invention, used in the insulated part of a three-pin socket.

Dabei stellt die Fig. 1 eine Ansicht der Kabelanschluhseite des Isolierteils dar und die Fig. 2 bzw. 3 jeweils eine teilweise geschnittene Ansicht des Seitenteils bzw. der Buchsenanschlußseite.1 shows a view of the cable connection side of the insulating part and FIGS. 2 and 3 each show a partially sectioned view of the side part and the socket connection side.

In dem Isolierteil der Steckbuchse, von dem der Übersichtlichkeit halber nur der Anschlußblock 1 dargestellt ist, sind drei Schraubklemmen 2 angeordnet, von denen jede einen in einer zur Steckseite hin offenen Kammer 3 angeordneten Buchsenkontakt 4 trägt. Dieser ist aus zwei Klemmfederschenkeln 5 gebildet, die an einer Stelle unter Druck aneinander liegen und deren Endteile 6 derart nach außen umgebogen sind, daß sich eine V-förmige Buchsenöffnung ergibt, die ein leichtes und sicheres Einführen von Steckerstiften ermöglicht.In the insulating part of the socket, of which only the connection block 1 is shown for the sake of clarity, three screw terminals 2 are arranged, each of which carries a socket contact 4 arranged in a chamber 3 which is open towards the plug side. This is formed from two clamping spring legs 5, which lie against each other at one point under pressure and whose end parts 6 are bent outwards in such a way that a V-shaped socket opening results, which enables easy and safe insertion of plug pins.

Die Schraubklemmen 2 bestehen jeweils aus einem im Stanzverfahren hergestellten U-förmig gebogenen Blechteil 7, dessen einer längerer Schenkel mit seinem Endteil 8 duer zur Richtung der Klemmschraube 9 abgewinkelt ist, auf dem freien Ende des kürzeren Schenkels aufliegt und eine Ausnehmung zum Durchführen des Gewindeteils lo der Klemmschraube 9 aufweist, sowie einer zwischen den Schenkeln angeordneten Mutter 11, in welche die Klemmschraube 9 zum Anklemmen von beispielsweise mit Kabelendhülsen 12 versehenen LeitErn 13 eindrehbar ist und die zur Halterung mit seitlich abragenden Schultern 14 Fenster 15 der Schenkel durchsetzt. Zur Sicherung der Klemmschraube 9 ohne zusätzliche Teile sind jeweils zwei einander gegenüberliegende Randteile 16 der Ausnehmung derart in Schraubrichtung abgebogen, daB sie unter leichtem Druck am Gewindeteil lo der Klemmschraube 9 anliegen.The screw terminals 2 each consist of a U-shaped sheet metal part 7 produced in the stamping process, the longer leg of which is angled with its end part 8 toward the direction of the clamping screw 9, rests on the free end of the shorter leg and has a recess for carrying out the threaded part lo the clamping screw 9, and a nut 11 arranged between the legs, into which the clamping screw 9 for clamping example as provided with cable end sleeves 12 conductors 13 can be screwed in and passes through the window 15 of the legs for mounting purposes with shoulders projecting laterally. To secure the clamping screw 9 without additional parts, two mutually opposite edge parts 16 of the recess are bent in the screwing direction in such a way that they bear against the threaded part 10 of the clamping screw 9 under slight pressure.

Die Schraubklemmen 2 sind in entsprechenden Kammern 17 des AnschluBblocks 1 einfach und zweckmäßig dadurch befestigt, daß an Fortsätzen 16 der Schenkel des U-förmigen Blechteils 7 angebrachte Rastnasen 19 entsprechende Kanten der Kammern 17 hintergreifen.The screw terminals 2 are fastened in corresponding chambers 17 of the connection block 1 simply and expediently in that latching lugs 19 attached to extensions 16 of the legs of the U-shaped sheet metal part 19 engage behind corresponding edges of the chambers 17.

Der bogenförmige Abschnitt des U-förmigen Blechteils 7 bildet zusammen mit der Stirnfläche der Klemmschraube 9 die Buchsenklemme. Darüber hinaus ist jedoch auch eine Leiterklemmung zwischen Schraubenkopf 2o und querliegendem Endteil 8 möglich. Dieses ist derart bemessen und abgebogen, daß es beidseitig über die Schenkel hinausragt und seine Länge dem Durchmesser des Schraubenkopfes 20 entspricht. Damit ist eine Auflagefläche geschaffen, die einerseits stabil und zum anderen großflächig genug ist, um nicht nur das Einklemmen von Kabelschuhen bzw. - ösen 21, sondern auch von Drähten bzw. Litzen 22 sicher zu gewährleisten.The arcuate section of the U-shaped sheet metal part 7 forms, together with the end face of the clamping screw 9, the socket clamp. In addition, however, a conductor clamping between screw head 2o and transverse end part 8 is also possible. This is dimensioned and bent such that it protrudes on both sides over the legs and its length corresponds to the diameter of the screw head 20. This creates a support surface that is stable on the one hand and large enough on the other hand to ensure not only the clamping of cable lugs or eyelets 21, but also of wires or strands 22.

Zur Vermeidung von Verletzungen oder gar eines Abscherens von Drähten bzw. Litzen beim Drehen des Schraubenkopfes 20 und zur sicheren Klemmung dieser Leiter ist zwischen Schraubenkopf 20 und der Auflagefläche eine Klemmplatte 23 vorgesehen.In order to avoid injuries or even shear off of wires or strands when turning the screw head 20 and to securely clamp this conductor, a clamping plate 23 is provided between the screw head 20 and the contact surface.
