Abstract

A strain relief device for at least one supply line. The strain relief device can be or is disposed on a line-guiding apparatus for guiding the at least one supply line and has at least one main body, which comprises at least one coupling means for the fastening of the at least one supply line to said coupling means and thus to the strain relief device in such a way that strain is relieved. At least one preferably flexible coupling element is provided, which can be disposed so as to peripherally surround the coupling means and the line to be fixed on the coupling means and which surrounds the line together with the coupling means in the form of a loop. There are fastening means on the main body for fastening the main body to the strain relief device in such a way that tensile force is absorbed. A guide element having a guide region for the coupling element is provided adjacent to the at least one coupling means. The guide region is designed to guide the coupling element as the coupling element is transferred from a position at a distance from the coupling means to the position of the coupling element in which the coupling element fastens the supply line to the coupling means in such a way that strain is relieved.

First claim

What is claimed is:

1 . A strain relief device for at least one or more supply lines, comprising:
wherein the strain relief device is arrangeable or arranged on a line-guiding apparatus for guiding the at least one supply line, wherein the strain relief device has at least one base body, which comprises at least one coupling means for the strain-relieving fastening of the at least one supply line thereto and thus to the strain relief device, wherein at least one coupling element is provided, which is arrangeable peripherally surrounding the coupling means and the line to be fixed thereto and, in the state of the supply line fixed in a strain-relieving manner, surrounds the line in a loop together with the coupling means, wherein the base body has fastening means for the tensile-force-absorbing fastening thereof to at least one of the strain relief device or an underlying surface or another apparatus, wherein a guide element with a guide region for the coupling element is provided adjacent to the at least one coupling means for the strain-relieving coupling of the supply line, wherein the guide region is formed to guide the coupling element during a transfer of the coupling element from a position of the coupling element spaced apart from the coupling means into its position fastening the supply line to the coupling means in a strain-relieving manner, wherein
(i) the guide region is formed in order, during an infeed of the coupling element laterally to and in the direction of the coupling means, to divert the coupling element, in interaction with the guide region, around the coupling means, with the result that the coupling element emerges from the guide region on this other side of the coupling means; or
ii) the guide region is formed in order to guide the coupling element during an infeed of the coupling element axially in the direction of the coupling means; or
iii) the guide region is formed in order, during an infeed of the coupling element laterally to and in the direction of the coupling means, to divert the coupling element, in interaction with the guide region, around the coupling means, with the result that the coupling element emerges from the guide region on this other side of the coupling means, and the guide region is formed in order to guide the coupling element during an infeed of the coupling element axially in the direction of the coupling means.

2 . The strain relief device according to claim 1 , wherein the guide region is formed in order, during an infeed of the coupling element, to divert the latter around the coupling means, with the result that the coupling element emerges from the guide region on the other side of the coupling means in relation to the infeed with a directional component which is opposed to the infeed direction of the coupling element.

3 . The strain relief device according to claim 1 , wherein the respective coupling means and the guide element with the guide region are arranged extending away from the central region of the base body.
