Description

[0001] The invention relates to a cable feedthrough, a use of a cable feedthrough and a method for equipping a cable feedthrough.

[0002] Cable penetrations for passing cables through a wall, for example, are generally known from the prior art. For instance, DE 10 2020 126 444 A1 discloses a cable penetration with a base frame and a plurality of cable penetration modules. Another cable penetration is known from WO 2018 / 096136 A1.

[0003] A disadvantage of conventional cable glands is that the mounting aids must be inserted individually and removed again after the insert modules have been installed. Once installed, the insert modules are only stabilized by the vertical webs in the frame.

[0004] The object of the present invention is therefore to provide an improved cable routing, an improved application, and an improved method. In particular, it is an object of the invention to provide a cable routing, an application, and a method in which insert modules can be flexibly placed in a frame and, in particular, exhibit improved stability in the assembled frame.The object is achieved according to the invention by means of a cable gland comprising at least one first frame part and at least one second frame part as well as a number of insert modules, wherein the first frame part comprises at least one base web and at least two vertical webs, wherein the second frame part can be arranged on the vertical webs to form at least one circumferential frame, wherein at least one assembly aid is arranged between at least two vertical webs, wherein the at least one assembly aid is materially bonded to the base web and has at least one predetermined breaking point, wherein at the predetermined breaking point the assembly aids can be separated from and removed from the first frame part, so that insert modules of different widths can be inserted into the cable gland.

[0005] Furthermore, the problem is solved according to the invention by using a cable gland described above for passing cables through a wall.

[0006] Furthermore, the problem is solved according to the invention by means of a method for equipping a cable gland described above, comprising the steps Providing a first frame part, a second frame part and a number of insert modules, inserting at least one insert module between two vertical webs of the first frame part or between a vertical web and an assembly aid of the first frame part or between two assembly aids of the first frame part, wherein at least one assembly aid is removed from the first frame part at a predetermined breaking point if a distance between a vertical web and an assembly aid or between two assembly aids is less than a nominal width of an insert module, arranging the second frame part on the vertical webs of the first frame part.

[0007] A cable gland comprising at least one first frame section and at least one second frame section, as well as a number of insert modules, is proposed. The first frame section includes at least one base web and at least two vertical webs, wherein the second frame section can be arranged on the vertical webs to form at least one circumferential frame. At least one mounting aid is arranged between at least two vertical webs, wherein the at least one mounting aid is materially bonded to the base web and has at least one predetermined breaking point, wherein the mounting aids can be separated from and removed from the first frame section at the predetermined breaking point, so that insert modules of different widths can be inserted into the cable gland.

[0008] The proposed cable gland allows for the quick, easy, and, above all, space-saving insertion of long components, such as electrical cables, pneumatic hoses, hydraulic hoses, and / or fiber optic cables, into control cabinets, housings, or machines. A particularly advantageous feature is the use of insert modules adapted to the long components being routed. The pre-scored breaking point allows the respective mounting aid to be removed from the first frame section. At this point, the mounting aids can be separated from the first frame section and removed, enabling the use of insert modules of varying widths within the cable gland. The mounting aids are permanently attached to the base web and are thus captive.Advantageously, the mounting aids can be easily separated from the first frame part, preferably without tools, or broken off at the predetermined breaking point. Furthermore, the mounting aids advantageously improve the stability of the installed cable gland.

Preferably, the fracture surface is essentially flush with a first surface of the first side of the base web. In another embodiment, the predetermined breaking point is located at a position on the assembly aid spaced apart from the base web. For example, at least one predetermined breaking point is located approximately in the center of the assembly aid. In one embodiment, the assembly aid comprises at least two predetermined breaking points. Advantageously, the assembly aid can thus be shortened and / or completely removed as needed, particularly without tools.

[0023] The term "essentially" indicates a tolerance range that is acceptable to a person skilled in the art from an economic and technical point of view, such that the corresponding feature is still recognizable as such or is realized.

[0024] The cable entry system comprises at least one second frame section. Advantageously, the insert(s) in the first frame section can be held by means of the second frame section.

In one embodiment, the second frame section comprises at least one plug-in head receptacle, in particular for receiving at least one plug-in head of at least one assembly aid.

[0025] In one embodiment, the second frame part is provided with positioning elements, preferably corresponding to the receptacles of the vertical webs. Preferably, the positioning elements are assigned to the receptacles for the fasteners. Advantageously, the positioning elements facilitate assembly, as they ensure alignment of the receptacles of the second frame part and the receptacles of the vertical webs.

[0026] According to the invention, the cable gland comprises a number of insert modules. Advantageously, the first frame part can be fitted with, for example, one to about ten insert modules. In one embodiment, the cable gland is designed as a set comprising at least the first and second frame parts and at least one insert module. The set can include a plurality of insert modules, preferably one to about 20. In one embodiment, the set comprises a plurality of insert modules that are particularly suitable for different applications. Preferably, the set comprises a number of insert modules that cannot all be inserted into the first frame part simultaneously. Advantageously, when fitting the first frame part with the insert modules, a selection can be made from a plurality of different insert modules in order to adapt the cable gland to a specific application.The insert module preferably comprises a rubber-elastic material. Advantageously, at least one long component can be guided through the insert module. In one embodiment, the insert modules each have a number of long component receptacles. In another embodiment, at least one insert module does not have a long component receptacle. Advantageously, an insert module without a long component receptacle can be used as a blanking plug.

[0027] Preferably, insert modules of different widths can be inserted into the first frame part. Preferably, insert modules with a first width can be inserted between two assembly aids, an assembly aid and a vertical web, or two vertical webs that have a first distance between them. More preferably, insert modules with a second width can be inserted between two assembly aids, an assembly aid and a vertical web, or two vertical webs that have a second distance between them.

[0028] Preferably, at least one insert module is inserted into the first frame part. More preferably, the first frame part is equipped with a plurality of insert modules. Preferably, the first frame part is equipped, or can be equipped, with insert modules such that these substantially completely fill the space between the base web and the second frame part.

[0029] An exemplary cable gland comprises a first frame section with a base web and three vertical webs arranged on one side of the base web. Two mounting aids are arranged, by way of example, between the first and second vertical webs. A third mounting aid is arranged, by way of example, between the second and third vertical webs. A second frame section, which can be placed onto the vertical webs, includes, by way of example, receptacles for fasteners, which are, for example, designed as screws. Positioning elements are associated with the receptacles, each of which can be inserted into receptacles on the end faces of the vertical webs. The receptacles on the vertical webs each include internal threads into which the fasteners can be screwed.The outer vertical webs, that is, the first vertical web and the third vertical web, include, for example, fastening holes by means of which the first frame part or the cable entry can be attached to a wall, for example of a housing, for example by means of screws or rivets.

[0030] The at least one assembly aid is materially bonded to the base web. The assembly aid includes, for example, a guide section adjacent to the base web. Furthermore, the assembly aid includes, for example, a plug-in head located on the side facing away from the base web. The plug-in heads of the assembly aid engage in plug-in head receptacles of the second frame part. The assembly aid also includes a predetermined breaking point, which, for example, is directly associated with the base web. The predetermined breaking point is, for example, designed as a one-sided notch that weakens the material of the assembly aid in a defined manner, allowing it to be removed from the first frame part without tools.

[0031] Once the second frame part is mounted onto the vertical struts of the first frame part, a surrounding frame is formed.

[0032] The predetermined breaking point, designed as an example of a one-sided notch, is shaped such that it transitions seamlessly into the first side of the base web. The predetermined breaking point extends, for example, approximately half the width of the mounting device, thus allowing for convenient tool-free removal of the mounting device.

[0033] The first frame section can be fitted with insert modules that are placed between the vertical webs or the assembly aids. The insert modules are designed for different long components. For example, some insert modules each include one long component holder. Other long component holders have different diameters. Some insert modules include two long component holders. Furthermore, some insert modules include more than two, for example, three or four long component holders. For example, some insert modules do not include any long component holders or openings and can be used, for instance, as blanking plugs. The assembly aids simplify the precise positioning of the insert modules during assembly and also provide the added benefit of high stability in the assembled state.For example, insert modules with different widths and / or heights can be inserted into the first frame part.

[0034] In another exemplary embodiment of the cable gland, the mounting aids are designed without a plug-in head that engages with the second frame part. The mounting aids extend close to the second frame part but do not touch it, even when the second frame part is mounted on the first. In particular, the mounting aids maintain a distance from the second frame part. This design eliminates the need to thread the mounting aids precisely into plug-in receptacles of the second frame part, thus significantly simplifying assembly.

[0035] Furthermore, the use of the cable gland described above for routing cables through a wall is proposed. In particular, the cable gland is used with a number of different insert modules.

[0036] Furthermore, a procedure for fitting components to a cable gland described above is proposed, comprising the following steps: Providing a first frame part, a second frame part and a number of insert modules, inserting at least one insert module between two vertical webs of the first frame part or between a vertical web and an assembly aid of the first frame part or between two assembly aids of the first frame part, wherein at least one assembly aid is removed from the first frame part at a predetermined breaking point if a distance between a vertical web and an assembly aid or a distance between two assembly aids is less than a nominal width of an insert module, arranging the second frame part on the vertical webs of the first frame part.

[0037] In accordance with the invention, a distance between two assembly aids is smaller than a nominal width of an insert module if the distance is at least about 5%, preferably at least about 10%, more preferably at least about 25%, more preferably at least about 25% to about 90%, more preferably about 25% to about 75% smaller than the nominal width of the insert module.

[0038] In one embodiment, the insert module has a nominal width that is approximately 1% to approximately 5% greater than the distance between a vertical web and an assembly aid or the distance between two assembly aids. Preferably, the insert module is installed under preload between a vertical web and an assembly aid or the distance between two assembly aids.
