[0004] An object of the invention is to provide an improved cable fastening component.

[0005] The object is achieved according to claim 1 by a cable fastening component, wherein the cable fastening component can be fastened in a groove with an undercut, wherein the cable fastening component has at least one receptacle for a cable and / or a cable tie, wherein the cable fastening component has a fastening adapter for the groove, wherein the fastening adapter has a first section with a first dimension, which allows the fastening adapter to be inserted into the groove perpendicular to the groove, wherein the cable fastening component with the fastening adapter can be rotated by 90° in the groove, so that a second section with a second dimension, which is wider than the opening of the groove, is arranged under the groove shoulder, wherein at least one wedge-shaped section is provided,wherein the wedge-shaped section is moved under the groove shoulder during the rotational movement and the cable fastening component is clamped with the fastening adapter under the groove shoulder.

[0006] The cable fastening component is preferably made of plastic. In particular, the cable fastening component is manufactured using an injection molding process. The cable fastening component is preferably a one-piece component without any moving parts.

[0007] The groove is, for example, part of a profile rail, for example an extruded profile. The profile rail can be part of a mounting structure. The profile rail can also be part of a housing, in particular a sensor housing, for example a light grid housing. The profile rail is preferably made of aluminum. However, the profile rail can also be made of steel or stainless steel, for example. The profile rail has a square or rectangular cross-section and has, for example, a longitudinal groove or slot on each long side. The groove or longitudinal groove has an undercut on both sides which is formed by groove shoulders. T-nuts can be inserted into the groove, for example to attach sensors, for example light grids.

[0008] The groove can have a rectangular cross-section. However, the groove can also have other cross-section shapes. For example, a recess for cable routing can be provided in the groove.

[0009] The undercut is formed by two projections that narrow the groove on the outside of the profile rail on both sides, so that the groove is open to the outside of the profile rail, but the undercuts can serve as fastening surfaces for sliding blocks or the fastening adapter of the cable fastening component.

[0010] The receptacle for a cable can be formed by a channel in the cable fastening component. A cable can be attached to the receptacle. The cable is preferably a connecting cable for a sensor, in particular a light grid.

[0011] The cable is, for example, a multi-core cable. The cable is round, for example, and has a diameter of approximately 2 mm to approximately 10 mm. For example, the cable has a diameter of approximately 3 mm.
