Knickschutztülle für Leitungen, insbesondere der Fernmeldetechnik Anti-kink sleeve for cables, especially for telecommunications
Die Neuerung betrifft eine Knickschutztülle zum Einführen von Anschlußkabel in Gehäuse von Fernmeldeendgeräten mit einer Nut zur Halterung der Knickschutz He in der Wandung des Gehäuses.The innovation concerns a bend protection sleeve for inserting connecting cables into the housing of telecommunications terminals with a groove for holding the bend protection sleeve in the wall of the housing.
Eine derartige Knickschutztülle ist bereits bekannt. So wird in der DE-OS 29 47 520 eine Knickschutztülle für Leitungen, insbesondere der Fernsprechtechnik beschrieben, welche zur knickfreien Einführung von Anschlußkabel in Gehäuse von Fernsprechgeräten dient. Die bekannte Knickschutztülle weist eine Nut auf, welche an drei Seiten des Körpers der Knickschutztülle angebracht ist. Die Nut verläuft auf dem Umfang des Körpers, und zwar senkrecht zur Symmetrieachse desselben. Die Knickschutztülle wird von. oben in eine entsprechende Öffnung des Gehäuses eingesetzt und durch Stege, die an der Wandung des Gehäuses angebracht sind, gehalten, inOem die Stege in die Nut eingreifen.Such an anti-kink sleeve is already known. For example, DE-OS 29 47 520 describes an anti-kink sleeve for cables, particularly in telephone technology, which is used for the kink-free insertion of connecting cables into the housing of telephone devices. The known anti-kink sleeve has a groove which is attached to three sides of the body of the anti-kink sleeve. The groove runs along the circumference of the body, perpendicular to its axis of symmetry. The anti-kink sleeve is inserted from above into a corresponding opening in the housing and held by webs which are attached to the wall of the housing, whereby the webs engage in the groove.
Nachteilig bei dieser bekannten Knickschutztülle ist, daß diese nur in einer bestimmten Position in das Gehäuse eingesetzt werden kann, nämlich dann, wenn die nicht mit einer Nut versehene Seite nach oben weist.The disadvantage of this known anti-kink sleeve is that it can only be inserted into the housing in a certain position, namely when the side without a groove is facing upwards.
Die Aufgabe der Neuerung besteht nun darin, eine Knickschutztülle der bekannten Art anzugeben, bei welcher beim Einsetzen in das Gehäuse auf die Lage nicht geachtet werden muß.The aim of the innovation is to provide a kink protection sleeve of the known type, where no attention needs to be paid to the position when inserting it into the housing.

Diese Aufgäbe wird dadurch gelöst, daß der Querschnitt der Knickschutztülle im Bereich der Nut quadratisch ausgebildet ist Und die Wandung des Gehäuses entsprechend geformt ist,This task is solved by the cross-section of the anti-kink sleeve being square in the area of the groove and the wall of the housing being shaped accordingly,
Die Neuerung wird anhand eines AusfUhrungsbeispiels näher erläutert, welches in der Zeichnung dargestellt ist. Es zeigt:The innovation is explained in more detail using an example, which is shown in the drawing. It shows:

Die aus Gummi gefertigte Knickschutztülle 1 weist eine axiale öffnung zur Aufnahme des Anschlußkabels auf. Die Knickschutztülle 1 ist mit einer Nut 3 versehen, wobei diese Nut derart susgebildet ist, daß ein quadratischer Querschnitt 6 entsteht.The anti-kink sleeve 1 made of rubber has an axial opening to accommodate the connecting cable. The anti-kink sleeve 1 is provided with a groove 3, whereby this groove is formed in such a way that a square cross-section 6 is created.

Durch die Ausbildung des quadratischen Querschnitts im Bereich der Nut der Knickschutztülle kann diese in vier verschiedenen Positionen in das Gehäuse eingesetzt werden, so daß ein Verdrehen vor dem Einsetzen wie bei der bekannten Knickschutztülle nicht mehr notwendig ist.Due to the design of the square cross-section in the area of the groove of the anti-kink sleeve, it can be inserted into the housing in four different positions, so that twisting before insertion, as with the known anti-kink sleeve, is no longer necessary.
