[0011] The aim of the invention is to at least reduce the risk of a cable break on a cable path from or to an electrical and / or electronic device.

[0012] This object is achieved by the subject matter of the independent claims. Further embodiments emerge from the dependent claims and the following description.

[0013] One aspect relates to a cable fastening accessory comprising a cylinder segment having a surface with a predetermined radius of curvature. The surface is configured to bend a cable having an electrically conductive core at least partially around the surface of the cylinder segment. The radius of curvature of a portion of the surface configured to make direct contact with the cable is greater than or equal to six times the diameter of the cable core.

[0014] The cylinder segment may be hollow - e.g., in the form of a shell - or solid and / or anything "in between", e.g., it may be partially solid, with stabilizing ribs extending radially and / or axially from a central axis of the cylinder segment to a region below the surface of the cylinder segment. The cylinder segment may not be a "mathematically exact" cylinder segment. Accordingly, the radius of curvature and the predefined angle of the cylinder segment may have deviations from a "mathematically exact" definition of the radius and / or angle of a cylinder segment. The cable fastening accessory is configured to bend the cable at least partially around the surface of the cylinder segment.Therefore, at least areas of the surface of the cylinder segment that are adapted and / or designed for direct contact with the cable have a radius of curvature that is greater than or equal to six times the diameter of the electrically conductive core of the cable.

[0015] The cable may consist of one cable, several cables, a cable bundle (e.g. arranged horizontally), a cable stack or cable bundles and / or other cable arrangements.

[0016] The surface may be partially discontinuous or broken. The width of the surface may vary along the radius of curvature. The cylinder segment may include at least one boundary region near its axial ends, which may be, for example, rounded, flattened, stepped, and / or other shapes or combinations of these shapes. Since neither the discontinuous region(s) nor the edge region(s) are in direct contact with the cable, these regions, particularly at their boundaries, may have a smaller radius of curvature.

[0017] One advantage of the cable fixing accessory is that it ensures a minimal bend radius by simply guiding the cable to be installed over the surface of the cable fixing accessory, thus protecting the cable(s) from breakage, even when bent around an edge, corner, or the like. Furthermore, this can help protect the cable's insulation from damage. The cable fixing accessory can also at least help

[0018] To meet industry standards in a system of electrical and / or electronic components, in particular the standard DIN EN IEC 61010-2-201:2018.

[0019] In at least some embodiments, the cable fastening accessory may carry or otherwise display an instruction not to use it for cables with a conductive core diameter greater than one-sixth of the surface area.

[0020] In at least some embodiments, the angle of the cylinder segment is between 30° and 190°, for example, between 60° and 150°, particularly between 75° and 95°. Cylinder segments with these angles have proven particularly useful for protecting the cable(s) from breakage.

[0021] In at least some embodiments, the cable fastening accessory further comprises an extension element, wherein the extension element extends in a direction substantially tangential to a central axis of the cylinder segment and has a flat and / or convex surface. The surface of the extension element is configured to increase the surface area of ​​the cylinder segment, and the radius of curvature of the surface of the cylinder segment and the extension element is greater than or equal to six times the diameter of the cable.

[0022] The cable fastening accessory—with or without an extension element—can be formed from a single piece or consist of multiple pieces or parts. The extension elements can be flat and / or convex. This shape can advantageously provide the flexibility to route a cable fastening accessory around complicated corners and / or edges. This shape can also allow the flexibility to adapt it to special manufacturing processes, e.g., for special molds.

[0023] In at least some embodiments, the surface is made of a rubber-like material, such as silicone rubber and / or similar materials. This can provide anti-slip protection for the cable(s). Furthermore, this material can have a softer surface that helps protect against harsh movements of the cable(s) caused by vibrations and / or other forces, thus protecting the core of the cable(s) from breakage.

[0024] In at least some embodiments, the cable fastening accessory further comprises at least one edge element, wherein the at least one edge element protrudes radially from the surface of the cylinder segment and / or the extension element.

[0025] The edge elements can have any shape, e.g. cylinder, rectangle, bracket and / or other. The edge elements can have a groove. The height of the edge element can depend on the intended function. Some edge elements can be designed to protect a cable bundle or stack - even with a high number of cables - from shifting to the right and / or left, depending on the position of the edge element(s). Some edge elements can be designed for holding, e.g. a cable tie, which can be designed to be looped around the cables. This can further help to make the cable(s) robust against vibrations and / or manual or other forces and / or against permanent movement caused e.g. by vibrations of the machine in which they are located.Additionally, this can prevent the cables from slipping out of a plug (or other electrical device) or the plug from losing contact with the device to which it is mounted.

[0026] In at least some embodiments, the cable fastening accessory further comprises a fastening element, wherein the fastening element is configured to secure the cable to the cable fastening accessory. The fastening element may, for example, be a clamp, a cable tie, a cable tie, and / or another element configured and / or suitable for securing the cable(s) to the cable fastening accessory.

[0027] In one embodiment, the fastening element is designed to wrap axially around the cylinder segment and / or to be guided around or through at least one of the edge elements. This can be achieved, for example, by a type of groove in the cylinder segment.

[0028] Alternatively or additionally, the cable fastening accessory may comprise a first passage through the cylinder segment and / or a second passage through at least one of the edge elements, wherein the fastening element is configured to pass through the first passage and / or the second passage. This may facilitate the installation of the fastening element and / or contribute to a secure attachment of the cable(s).

[0029] In at least some embodiments, the cable fastening accessory further comprises a retaining element, wherein the retaining element is configured to hold the cable fastening accessory to a housing.

[0030] The term "enclosure" should be interpreted broadly. This may be a housing of an electrical device or system, a part that is attached or somehow connected or connected to an electrical device or system, and / or may be another type of "wall-like element" - possibly with openings - suitable for holding and / or securing the cable fixing accessory thereto. The holding element may, for example, comprise a barb and / or an adjusting hook. The barb may provide a snap-in mechanism for securing the cable fixing accessory to the housing. For example, the holding element may advantageously be attached to a so-called ventilation grille area of ​​an electrical device without covering it and / or disrupting the airflow of the device. The holding element may provide means for integrating the cable fixing accessory into the ventilation grille.

[0031] In at least some embodiments, the cable fastening accessory is part of a housing or housing element. This integration allows the housing and / or housing elements—such as side panels, ventilation grilles, and / or other housing elements—to be designed to protect cables from breakage.

[0032] In one embodiment, the cable fastening accessory comprises two or three edge elements. The edge elements can protrude from the surface on the left, right, and / or center, so that one, two, or even more cable bundles are attached to the cable fastening accessory.

[0033] In at least some embodiments, the cylinder segment is hollow, solid, or partially solid. The cylinder segment may include internal ribs radially and / or axially to a central axis of the cylinder segment. The cylinder segment may be made of plastic. The cable retention accessory may be embodied as an optional plastic part that can be plugged onto the electrical and / or electronic device (e.g., a programmable logic controller, PLC) or its housing by the end user and / or may be an integral part of the housing.

[0034] Another aspect relates to the use of a cable fastening accessory as described above and / or below for bending a cable along a surface of the fastening accessory with a radius of curvature of the surface greater than or equal to six times the diameter of the cable.

[0035] Another aspect relates to an electronic device comprising a housing of a cable fastening accessory as described above and / or below. The electronics may be a programmable logic controller (PLC), or an I / O device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Fig. 1 schematically shows a perspective view of a cable fastening accessory 10 according to one embodiment. The cable fastening accessory 10 comprises a cylinder segment 20 with a surface 22. The surface 22 has a predetermined radius of curvature 24 and a predetermined angle 26. For the sake of better illustration, this embodiment has the shape of a cylinder segment with a predefined angle 26 of 90°. However, this should not be understood as a limiting property of the cable fastening accessory 10. Other embodiments may have angles 26, for example between 30° and 190°, possibly between 60° and 150°, in particular between 75° and 95°. Another embodiment may further comprise extension elements (see e.g. Fig. 4) that may alter the overall shape of the cable fastening accessory 10 away from a "mathematically regular" cylinder segment. Further embodiments may include fractures and / or through-holes in the surface 22 and / or body of the cylinder segment 20 caused by a variety of reasons, including manufacturing limitations, the attachment of other components to the cylinder segment 20, design reasons, and / or other reasons.

[0039] The cable fastening accessory 10 is designed to fasten a cable 30 (not in Fig. 1) having an electrically conductive core 32 to at least partially bend around the surface 22 of the cylinder segment 20. In a region (or in a plurality of regions) of the surface 22 that is / are configured to be in direct contact with the cable 30, the radius of curvature 24 of the surface 22 is greater than or equal to six times the diameter 34 of the cable 30. This condition may not apply to regions of the surface 22 that do not have direct contact with the cable 30. These regions may include breaks, through-passages, and / or edge regions - e.g., the left or right edge - in or of the surface 22.

[0040] Fig. 1 further schematically shows an example of a boundary element 40. The boundary element 40 protrudes radially from the surface 22 of the cylinder segment 20. In further embodiments of the cable fastening accessory 10, which include an extension element 28 (not shown in Fig. 1), the limiting element 40 can protrude radially from the surface 22 of the extension element 28 and / or from the surface 22 of the cylinder segment 20. The edge elements 40 can have any shape, e.g., cylinder, rectangle, and / or other. The number of edge elements 40 can be one (as shown), two, or more. An embodiment with an edge element 40, which can be arranged, for example, near the right edge of the surface 22, can serve to prevent cables from sliding to the right. The edge element 40 can have a groove and / or a passage (not shown in Fig. 1); these elements of the boundary element 40 may be configured for fastening, e.g., a fastening element such as a cable tie and / or other types of fastening elements. The height 42 of the boundary element 40 may depend on the purpose for which the boundary element 40 is to serve. Examples may be a comparatively large height of the boundary element 40, e.g., for "aligning" a stack of cables and / or as a resistance of the cables to movement, or a comparatively low height of the boundary element 40, e.g., for providing a feedthrough for a cable tie.
