Description

Gegenstand der Neuerung ist eine Vorrichtung, bei welcher elektrische Leitungen mittels hohler Klemmhülse und Überwurfmutter festgeklemmt werden.
Die Zeichnung stellt die Anordnung in Fig. ι im Schnitt, in Fig. 2 in der Ansicht dar; Fig. 3 ist eine Ansicht und Fig. 4 ein Querschnitt durch den Anschlußkörper.
Klemmvorrichtungen, bei welchen die Leitungen durch Klemmhülse und Überwurfmutter festgeklemmt wurden, sind schon bekannt, doch haften diesen bekannten Konstruktionen erhebliche Nachteile an, die durch die Erfindung völlig vermieden werden.The object of the innovation is a device in which electrical lines are clamped by means of a hollow clamping sleeve and union nut.
The drawing shows the arrangement in Fig. Ι in section, in Fig. 2 in the view; Fig. 3 is a view and Fig. 4 is a cross section through the connector body.
Clamping devices in which the lines were clamped by clamping sleeves and union nuts are already known, but these known constructions have considerable disadvantages which are completely avoided by the invention.

Bei den bekannten Vorrichtungen drückt die Überwurfmutter den Klemmkegel zwischen Anschlußkörper und festzuklemmender Leitung ein. Da eine besondere Sicherung der Mutter nicht vorgesehen ist, so kann sich diese sehr leicht lockern, wodurch schwere Störungen infolge mangelnden Kontaktes eintreten. Dieser Fehler tritt besonders dann ein, wenn mittels solcher Vorrichtung Leitungen an Transformatoren oder Maschinen festgeklemmt werden, die im Betriebe stark vibrieren.In the known devices, the union nut presses the clamping cone between Connection body and cable to be clamped. As a special backup of the Nut is not provided, so it can loosen very easily, making it difficult Faults occur as a result of a lack of contact. This error occurs especially then on, if such a device is used to connect cables to transformers or machines that vibrate heavily in operation.

Durch die Erfindung wird nun eine völlige Sicherung der Mutter gegen Lockerung erzielt. The invention now completely secures the nut against loosening.

Die Klemmvorrichtung besteht ebenfalls aus einer geschlitzten Klemmhülse a, die mittels einer Überwurfmutter b in das Anschlußstück c eingedrückt wird. Die Klemmhülse legt sich hierbei fest um die Leitung d und bildet einen sehr innigen Kontakt zwischen dieser Leitung und dem Anschlußstück. Nach der Erfindung erhält nun das entsprechend der Klemmhülse konisch ausgebohrte Anschlußstück c einen oder mehrere Schlitze e, wodurch der außerordentliche Vorteil erreicht wird, daß sich beim Anziehen der Mutter b durch den Druck der Klemmhülse α das Anschlußstück c etwas auseinander spreizt und bei stärkerem Anzug sich außerordentlich fest in die Gewindegänge der Mutter b einlegt, so daß sie gegen unbeabsichtigte Lockerung geschützt ist. Die Reibung zwischen der Mutter b und dem Anschlußstück c ist so groß, daß schon eine erhebliche Rückwärtsdrehung der Mutter notwendig ist, ehe sie lose wird, während bei den früheren Ausführungen schon ein ganz geringes Rückwärtsdrehen zur völligen Lokkerung genügte, da gar keine Reibung zu überwinden war.The clamping device also consists of a slotted clamping sleeve a, which is pressed into the connecting piece c by means of a union nut b. The clamping sleeve is firmly attached to the line d and forms a very intimate contact between this line and the connector. According to the invention, the connector c drilled conically corresponding to the clamping sleeve receives one or more slots e, whereby the extraordinary advantage is achieved that when the nut b is tightened by the pressure of the clamping sleeve α, the connector c spreads apart a little and with stronger tightening extremely tightly inserted into the threads of the nut b , so that it is protected against inadvertent loosening. The friction between the nut b and the connection piece c is so great that a considerable backward rotation of the nut is necessary before it becomes loose, while in the earlier versions a very slight reverse rotation was sufficient for complete loosening, since no friction at all has to be overcome was.

Eine Vergrößerung des Kontaktes und eine weitere Sicherung gegen das Lockern der Überwurfmutter wird dadurch erreicht, daß die konische Klemmhülse in bekannter Weise auch an der Berührungsfläche mit der Überwurfmutter konisch gestaltet ist. An ihrer stärksten Stelle ist sie mit einer umlaufenden Nute versehen, um beim Auseinandernehmen der Verbindung sie zu fassen und aus dem Anschlußstück herauszuziehen.An enlargement of the contact and a further safeguard against loosening of the Union nut is achieved in that the conical clamping sleeve in a known manner is also designed conically at the contact surface with the union nut. On hers at its strongest point, it is provided with a circumferential groove so that it can be taken apart the connection to grasp it and pull it out of the connector.
