Description

Die Erfindung betrifft eine Maulklemme, insbesondere für elektrische Leitungen, bei der zur Sicherung sowohl gegen nachlassenden Klemmdruck infolge Fließens des garngeklemmten Materials als auch gegen Lockerung der Klemmschraube der Klemmdruck möglichst weitgehend federnd ist und bei der die Klemme selbst aus wenigen und einfach herzustellenden Teilen besteht. Bei bekannten derartigen Klemmen ist die Federung infolge des zu kleinen Federweges des zwischen Klemmschraube und anzuklemmendem Draht vorgesehenen U-förmigen Zwischenstückes unzureichend. In der Zeichnung ist die neue Klemme in Fig. i in Seitenansicht und in Fig. 2 in Draufsicht dargestellt.The invention relates to a jaw clamp, in particular for electrical Lines in which to secure both against decreasing clamping pressure as a result of flowing of the yarn-clamped material as well as the clamping pressure against loosening of the clamping screw is as resilient as possible and in which the terminal itself consists of a few and simple parts to be produced. In known such clamps, the suspension as a result of the too small spring deflection of the between the clamping screw and to be clamped Wire provided U-shaped intermediate piece inadequate. In the drawing is the new clamp shown in Fig. i in side view and in Fig. 2 in plan view.

Sie besteht erfindungsgemäß aus dem U-förmigen Zugfederbügel2, dessen oberer Schenkel eine Gewindebohrung zur Aufnahme der Klemmschraube q. besitzt und dessen anderer Schenkel beispielsweise kreisbogenförmig nach innen abgebogen ist, sowie aus dem gleichfalls U-förmigen Druckfederbügel 3, dessen unterer Schenkel beispielsweise kreisbogenförmig nach außen abgebogen ist, während der andere Schenkel mit der Klemmschraube in an sich bekannter Weise gekuppelt ist. Die Länge der Schraube ist derart bemessen, daß sie einen Spalt 6 gegenüber dem kreisbogenförmig abgebogenen Schenkel des Druckfederbügels 3 offen läßt, der der zulässigen Durchbiegung desselben entspricht. Hierdurch ist auch die Schraube selbst nicht nur mit dem Zugfederbügel 2, sondern auch mit dem Druckfederbügel 3 unverlierbar verbunden.It consists according to the invention of the U-shaped tension spring clip2, whose upper leg has a threaded hole for receiving the clamping screw q. owns and the other leg of which is bent inwards in the shape of a circular arc, for example, as well as from the likewise U-shaped compression spring clip 3, its lower leg for example, is bent outwardly in the shape of a circular arc, while the other leg is coupled to the clamping screw in a manner known per se. The length of the screw is dimensioned such that it has a gap 6 opposite the curved arcuate The leg of the compression spring clip 3 leaves open, the permissible deflection of the same is equivalent to. As a result, the screw itself is not only connected to the tension spring clip 2, but also captively connected to the compression spring clip 3.

Die beiden U-förmigen Bügel :2 und 3 werden aus gut federndem Material, zweckmäßig aus Federstahl, und in einfachster Weise durch Stanzen hergestellt. Die Klemme wird auf den eigentlichen Stromleiterbügel i, mit dem der anzuschließende Leitungsdraht 5 elektrisch verbunden werden soll und der aus gut leitendem Material, z. B: aus Kupfer, Aluminium oder Kupalblech, - besteht, aufgesteckt.The two U-shaped brackets: 2 and 3 are made of springy material, expediently made of spring steel, and made in the simplest way by punching. the The terminal is on the actual conductor bracket i, with which the Lead wire 5 is to be electrically connected and made of highly conductive material, z. B: made of copper, aluminum or copper sheet, - consists, attached.

Der Stromleiterbügel r kann nun im Querschnitt so kreisbogenförmig durchgebogen werden, daß er sich entweder an den entsprechenden Schenkel des Zugfederbügels 2 oder des Druckfederbügels 3 anschmiegt, so daß der anzuschließende Draht im-, ersteren Falle zwischen dem Stromleiterbügel i und dem Schenkel des Druckfederbügels 3 und im zweiten, gestrichelt angedeuteten Falle zwischen dem Stromleiterbügel i und dem Schenkel des Zugfederbügels a eingeklemmt wird. Durch diese Durchbiegung des Stromleiterbügels i nach unten oder oben ist es möglich, den Leitungsdraht wahlweise mit der einen oder anderen Seite des Stromleiterbügels i in Kontakt zu bringen, so daß z. B. bei Verwendung eines Kupalbleches für den Stromleiterbügel i an dieselbe Klemme sowohl Kupferals auch Aluminiumleitungen gleich einwandfrei angeschlossen werden können. Der anzuschließende Leitungsdraht 5 kann sowohl von vorn als auch von der Seite eingeführt werden.The current conductor clip r can now have a circular arc shape in cross section be bent so that it is either attached to the corresponding leg of the tension spring clip 2 or the compression spring clip 3 fits snugly so that the wire to be connected is the former case between the current conductor clip i and the leg of the compression spring clip 3 and in the second case, indicated by dashed lines, between the current conductor bracket i and the leg of the tension spring clip a is clamped. Because of this deflection the current conductor bracket i down or up, it is possible to select the conductor wire to bring it into contact with one or the other side of the conductor bracket i, so that z. B. when using a cup for the current conductor bracket i to the same Terminal both copper and aluminum lines connected properly can be. The lead wire 5 to be connected can both from the front and be introduced from the side.

Beim Anziehen der Klemmschraube q. biegt sich zuerst der im Querschnitt etwas schwächere Druckfederbügel3 so weit federnd zusammen, bis das Schraubenende an dem entsprechenden Schenkel zur Anlage kommt. Bis zu diesem Zeitpunkt ist nur ,der Teil der Schraube zwischen der Gewindeeinspannung und dem Schraubenkopf beansprucht, und zwar auf Zug. Bei weiterem Anziehen der Schraube biegt sich der Zugfederbügel2 federnd auseinander, wobei der Teil der Schraube zwischen der Gewindeeinspannung und dem Schraubenende zusätzlich beansprucht wird, und zwar auf Druck, so daß also der Schraubenquerschnitt doppelt ausgenutzt wird und somit trotz kleinster Abmessung sehr hohe Kräfte erzeugen kann. Da der untere Schenkel des Druckfederbügels 3 gleichzeitig als Zwischenlage dient, ist der Draht auch gegen Abscheren durch die Schraube selbst gesichert.When tightening the clamping screw q. the cross section bends first somewhat weaker compression spring clips3 so far resiliently together until the end of the screw comes to rest on the corresponding leg. Until that point is only , the part of the screw between the thread restraint and the screw head stresses, on train. If the screw is tightened further, the tension spring clip2 bends resiliently apart, with the part of the screw between the thread restraint and the end of the screw is additionally subjected to pressure, so that the screw cross-section is used twice and thus despite the smallest dimension can generate very high forces. Since the lower leg of the compression spring clip 3 at the same time serves as an intermediate layer, the wire is also protected against shearing by the screw itself secured.

Der grundsätzliche Gedanke der Federung kann selbstverständlich auch in der Weise ausgenutzt werden, daß der Leitungsdraht nicht, wie in Fig. z gezeichnet, senkrecht zur Zeichenebene, sondern um go° versetzt in der Zeichenebene von der Seite her bei entsprechender Gestaltung der unteren Schenkel der beiden Federbügel :2 und 3 eingeführt wird.The basic idea of the suspension can of course also be used be used in such a way that the lead wire does not, as shown in Fig. z, perpendicular to the plane of the drawing, but offset by go ° in the plane of the drawing Side with a corresponding design of the lower legs of the two spring clips : 2 and 3 is introduced.

Auch kann auf die zusätzliche Federung des Zugfederbügels 2 gegebenenfalls verzichtet werden und statt des letzteren ein an sich bekanntes, starres Gehäuse oder Kontaktstück verwendet werden.The additional suspension of the tension spring clip 2 can also be used if necessary be dispensed with and instead of the latter a known, rigid housing or contact piece can be used.
