Abstract

An anti-kink device for a cable is provided. The anti-kink device for a cable comprises:
an anti-kink bush which can be secured on a cable, wherein the anti-kink bush has at least one first snap-in element, a first connecting element which has an opening for the passage of the anti-kink bush, wherein the first connecting element has at least one second snap-in element, a second connecting element which can be connected to the first connecting element, wherein the at least one first snap-in element and the at least one second snap-in element are in such a form that, in a first position of the anti-kink bush relative to the first connecting element, they allow the anti-kink bush to be guided through the opening of the first connecting element and, in a second position of the anti-kink bush relative to the first connecting element, they can be locked together.

First claim

The invention claimed is:

1. An anti-kink device for a cable, having: an anti-kink bush which can be secured on a cable, wherein the anti-kink bush has at least one first snap-in element, wherein the anti-kink bush has guide projections which are offset relative to one another and form between them at least one guideway for the at least one second snap-in element of the first connecting element,
a first connecting element which has an opening for the passage of the anti-kink bush, wherein the first connecting element has at least one second snap-in element,
a second connecting element which can be connected to the first connecting element,
said anti-kink bush and said first connecting element being relatively rotatable between at least a first predetermined position and a second predetermined position, wherein the first predetermined position and the second predetermined position differ from each other,
wherein the at least one first snap-in element and the at least one second snap-in element are configured such that, in the first position of the anti-kink bush relative to the first connecting element, they allow the anti-kink bush to be guided through the opening of the first connecting element, wherein, in the first position, the at least one guideway is configured to cooperate with the at least one second snap-in element in order to guide the movement of the anti-kink bush through the opening in the first connecting element and, in the second position of the anti-kink bush relative to the first connecting element, they can be locked together, wherein in the second position, the at least one first snap-in element and the at least one second snap-in element are configured to block a movement of the anti-kink bush through the opening of the first connecting element, and wherein the at least one first snap-in element and the at least one second snap-in element are configured such that, in the second position, they establish an interlocking connection acting in the peripheral direction of the anti-kink bush and/or of the first connecting element, wherein the second connecting element is configured to fix the anti-kink bush and the first connecting element to one another in the second position.

2. The anti-kink device as claimed in claim 1 , wherein the at least one first snap-in element and the at least one second snap-in element can be transferred out of the first position into the second position and back by a relative movement between the anti-kink bush and the first connecting element.

3. The anti-kink device according to claim 1 , wherein at least one of the guide projections of the anti-kink bush has at least one first snap-in element.

4. The anti-kink device as claimed in claim 1 , wherein the guide projections are formed integrally with the anti-kink bush.

5. The anti-kink device as claimed in claim 1 , wherein the at least one second snap-in element is a snap-in projection which protrudes radially inwards.

6. The anti-kink device as claimed in claim 1 , wherein the at least one first snap-in element is a snap-in recess.

7. A method of fitting an anti-kink device for a cable as claimed in claim 1 , comprising the steps of:
rotating the anti-kink bush and/or the first connecting element into the first position, in which the at least one first snap-in element and the at least one second snap-in element allow the anti-kink bush to move through the opening of the first connecting element;
moving the anti-kink bush and the cable connected thereto through the first connecting element, wherein the anti-kink bush and the first connecting element are in the first position, wherein, in the first position, the at least one guideway cooperates with the at least one second snap-in element in order to guide the movement of the anti-kink bush through the opening in the first connecting element;
withdrawing the anti-kink bush and the cable in the first position through the opening in the first connecting element, wherein the anti-kink bush and the first connecting element are in the first position;
rotating the anti-kink bush and/or the first connecting element into the second position, in which the at least one first snap-in element and the at least one second snap-in element can be locked together, wherein in the second position, the at least one first snap-in element and the at least one second snap-in element are configured to block a movement of the anti-kink bush through the opening of the first connecting element;
locking the at least one first snap-in element and the at least one second snap-in element together, wherein the at least one first snap-in element and the at least one second snap-in element, in the second position, establish an interlocking connection acting in the peripheral direction of the anti-kink bush and/or of the first connecting element; and
connecting the first connecting element and the second connecting element, wherein the second connecting element fixes the anti-kink bush and the first connecting element to one another in the second position.
