Description

The invention relates to a cable wall feedthrough and an arrangement for passing cables through a wall and to a method for mounting a cable wall feedthrough.BackgroundCable wall feedthroughs, which may also be referred to as cable feedthroughs, serve to guide cables through a wall from one side to the other side. Such wall feedthroughs are used in particular in connection with the feedthrough of cables through a housing wall of a device or cabinet, for example a switch cabinet. Such wall feedthroughs may provide a seal, for example for sealing against the ingress of moisture and dirt.Wall feedthroughs can have a housing made of plastic, which is manufactured as an injection-molded component. In this case, the housing can be a frame or have a frame. In this or other known embodiments, the housing has a housing aperture which is arranged opposite a wall aperture through which the cables are to be guided.The document DE 10 2020 208 235 A1 describes a device for passing cables through a wall aperture surrounded by a wall. The apparatus is formed with a base frame configured to receive a main frame. Chambers are formed in the main frame for inserting grommets for strain relief and / or sealing of inserted strands. The base frame is designed for fastening to the wall surrounding the wall aperture and consists of at least two frame parts divided transversely to the plane of the wall aperture. The frame parts are connected to one another by a movement transversely to the feed-through direction, i.e. the running direction of the strands, to form the base frame. The mounting and sealing of the wall opening by the main and base frames takes place in such a way that the divided base frame is laid around the bundle of strands and closed in itself. It is only then mounted on the wall.Document DE 10 2021 201 300 B3 relates to a device for passing elongate strands through an aperture in a plate having a divided frame, which comprises a frame lower part and a frame cover, which are divided transversely to the running direction of the elongate strands to be inserted, and which has at least one chamber for inserting at least one elastic bushing. The frame includes means for securing the frame to the panel. The devices have hooks for fastening the frame in the aperture of the plate or in fastening bores in the plate, wherein at least two hooks are provided which are designed to be movable relative to one another. At least one of the hooks is designed as part of a link element or indirectly movable by it, which is movable relative to the frame transversely to the running direction of the accommodated elongate strands via a thread-screw combination.The document US 2010 / 0 187 371 A1 discloses a cable feedthrough for a switchgear cabinet, electrical cabinet or the like. In this case, the cable feedthrough is formed from two substantially identical feedthrough halves. The bushing halves are held together by two clamping devices. By inserting the clamping devices into grooves of the bushing halves, the cable bushing is held together.The document U.S. Pat. No. 8,563,877 B2 describes a modular frame for cable introduction, pipe passage or the like. The frame has at least two identical end modules. Depending on the desired dimensioning, one or more intermediate modules are arranged between the end modules. The modules form at least one opening for receiving a cable inlet, pipe passage or the like. The frame may cover the openings of the frame before receiving the cable inlet, pipe passage or the like.Document DE 10 2018 207 019 A relates to a wall feedthrough having a frame which is divided into at least two chambers by at least one intermediate web, wherein at least one bushing made of elastic material is arranged in each of the chambers, and wherein the bushing has at least one passage opening for receiving an elongate object to be guided through the wall. It is provided that in each case two grommets adjacent with an intermediate web therebetween are formed such that they overlap the intermediate web on at least one side of the frame in the longitudinal direction of the elongate articles over the entire height of a side edge of the grommet and sealingly contact one another.Document US 2013 / 0 228 657 A1 discloses a frame for cable feedthrough systems. The frame comprises a first frame part and a second frame part, each frame part comprising a recess and a protrusion. The protrusion of the first frame part is adapted to be inserted into the recess of the second frame part, and the protrusion of the second frame part is adapted to be inserted into the recess of the first frame part. The first frame part further comprises a locking element and the second frame part further comprises a locking element, wherein the locking elements in the assembled state can detachably connect the first frame part to the second frame part, wherein the locking elements comprise snap-in closures or wherein the locking elements comprise slide elements.SummaryIt is an object of the invention to specify an improved cable wall feedthrough for the feedthrough of cables through a wall and a corresponding arrangement and a method for mounting a cable wall feedthrough, in which in particular increased flexibility is provided during mounting.To achieve the object, a cable wall feedthrough for passing cables through a wall is provided according to independent claim 1. Furthermore, an arrangement for passing cables through a wall and a method for mounting a cable wall passage according to claims 10 and 11 are provided. Embodiments are the subject of dependent claims.According to one aspect, a cable wall feedthrough for passing cables through a wall is provided. The cable wall feedthrough has a divisible frame which, in the mounted state, surrounds a receiving space of the cable wall feedthrough which is configured to receive one or more sealing elements of the cable wall feedthrough, with the result that a guidance of cables received in each case in a sealing element through the receiving space in a feedthrough direction is made possible. The divisible frame is configured to be arranged on the wall surrounding a wall aperture of a wall in the assembled state in order to guide cables through the wall aperture in the feedthrough direction. The divisible frame has a first frame component and a second frame component, wherein the second frame component can be connected to the first frame component to form the divisible frame by the second frame component being brought up to the first frame component in the leadthrough direction and being connected to the first frame component by the movement in the leadthrough direction.According to a further aspect, an arrangement is provided for passing cables through a wall. The arrangement has a wall with a wall aperture, a cable wall passage according to the disclosure and at least one cable. The cable wall feedthrough is arranged on the wall in such a way that the divisible frame of the cable wall feedthrough is arranged on the wall surrounding the wall aperture. The at least one cable is arranged in a sealing element of the cable wall feedthrough in such a way that it is guided in the feedthrough direction through the receiving space of the cable wall feedthrough and the wall aperture.Preferably, the lead-through direction extends at an angle of less than 45 degrees to a perpendicular standing on a wall through which cables are to be guided. In particular, the feedthrough direction can run substantially perpendicular to the wall, for example perpendicular to the wall. In any case, the feed-through direction extends differently from a parallel direction to the wall, since in the case of a feed-through direction parallel to the wall, guiding of cables through a wall aperture of the wall would be impossible.The divisible frame can have a shape which is advantageous for a given application of the cable wall feedthrough. Preferably, the divisible frame has a rectangular or square cross section. In alternative embodiments, a circular or oval cross-sectional shape of the divisible frame is provided. Other, for example polygonal, cross-sectional shapes of the divisible frame are also included in the disclosure.For the purposes of the present disclosure, the divisible frame is in an assembled state when the second frame component is connected to the first frame component and the divisible frame is arranged on the wall surrounding a wall aperture of a wall in order to guide cables through the wall aperture in the feedthrough direction.In the sense of the present disclosure, the term cable feedthrough-and consequently also the term cable routed by means of the cable feedthrough-comprises, in addition to electrical cables, also lines, e.g. fluid lines such as hoses, and other strands which are usually routed with feedthroughs of the generic type, to which reference is also made, for example, in the document DE 10 2021 201 300 B3.In the cable wall feedthrough, it can be provided that the first frame component has one or more first connecting elements and that the second frame component has one or more second connecting elements. In this case, the one or more first connecting elements and the one or more second connecting elements are then formed with mutually matching shapes such that in each case a first connecting element and a second connecting element can be connected to one another by a movement in the feedthrough direction, forming a positive fit which restricts or prevents a relative movement of the first frame component and the second frame component with respect to one another in a direction perpendicular to the feedthrough direction. In particular, guide elements can thus be formed with the first connecting elements and the second connecting elements, which guide a movement during the connection of the first frame component and the second frame component. A respective dovetail connection or a similar form-fitting connection can be formed with the one or more first connection elements and the one or more second connection elements. It can be provided that the first or the second connecting element forms a projection, the cross section of which has an undercut, and the corresponding second or first connecting element has a recess corresponding to the projection. In this case, during the movement in the passage direction of the second frame component relative to the first frame component, the respective projection is then pushed into the respective cutout or vice versa, with the result that, when the first and second frame components are joined together, a movement in directions perpendicular to the passage direction is prevented.In general, in the sense of the present disclosure, a movement of the second frame component with respect to the first frame component is understood as a relative movement of the second frame component with respect to the first frame component (in particular in the direction of passage), wherein the second frame component can move relative to the stationary first frame component, the first frame component can move relative to the second frame component or the first and the second frame component can move relative to an outer coordinate system.The one or more first connecting elements and / or the one or more second connecting elements can be formed to taper conically in the feedthrough direction such that, during the movement in the feedthrough direction for connecting the second frame component to the first frame component, a self-centering of the second frame component with respect to the first frame component is provided. The direction of the tapering-i.e. positive or negative direction along the lead-through direction-is selected here to be correspondingly adapted to the arrangement of the relevant connection elements in relation to the intended mounting direction (along the lead-through direction). In such embodiments, the form-fit connection between the respective first connecting element and second connecting element is thus initially loose, i.e. with play, and permits a (restricted) movement perpendicular to the feed-through direction. Upon further movement in the lead-through direction, the play then decreases due to the conical shape of the connecting element / s, and a movement perpendicular to the lead-through direction is finally maximally restricted or prevented. The respective conical taper can extend along the feed-through direction over a section of the respective connecting element or over the entire respective connecting element. It should be noted that a conical tapering is not limited to a shape in the sense of a circular cone (or circular cone or circular truncated cone), but that the base surface of the cone shape can be suitably selected in accordance with the configuration of the respective cross section of the relevant connecting element.In the cable wall feedthrough, it can be provided that the first frame component has one or more first snap elements and that the second frame component has one or more second snap elements, wherein the one or more first snap elements and the one or more second snap elements are configured to form a snap connection. In this case, in order to form the snap connection, a first snap element and a second snap element engage one another in a snap-action manner by a movement in the feedthrough direction, such that the snap connection fixes the second frame component to the first frame component. A securing of the second frame component to the first frame component can thus be provided. This can allow tool-free mounting of the divisible frame. In particular, a connection between the first frame component and the second frame component can be provided by means of the connecting elements, which connection can be released without resistance or with low resistance by a movement opposite to the movement of the lead, wherein the frame components are then fixed or secured to one another by means of the snap elements. In this case, the snap connection can be designed in such a way that the fixing can no longer be released in a non-destructive manner. Alternatively, the snap connection can be designed such that the fixing can be released using a sufficient force and / or using a specific movement sequence. The snap elements may be formed on one or more of the respective connecting elements or separately therefrom.In general, snap connections are formed with snap elements interacting with one another in a snap-action manner. For providing a snap connection, first or second snap elements can be formed, for example, with projections, in particular so-called snap hooks, and corresponding second or first snap elements with counter elements engaging around the projections in a snap-fitting or latching manner. Alternatively, the first and the second snap-in elements can each be formed with projections as well as with counter elements, wherein the projections and counter elements are then arranged correspondingly, when the frame components are connected, in mutually engaging manner on the first frame component and the second frame component. In the respective embodiments, snap projections can be arranged or formed on projecting arms in order to achieve a suitable arrangement with respect to the counter elements. Counter elements can be formed, for example, as recesses in another element, in particular as recesses in the first or second frame component. Alternatively, counter elements may be formed as annular elements, wherein the annular elements may be formed matching the projections with a round or polygonal ring shape. As a further alternative, counter elements can be designed as projecting arms provided with counter projections, which interact with the snap projections in a snap-in or latching manner. In alternative embodiments, a so-called ring snap connection can be provided, in which a circumferential snap bead engages in a circumferential recess in a snap-fitting manner.A sealing device can be arranged on an underside of the divisible frame, wherein the sealing device is configured to seal the cable wall feedthrough with respect to a wall on which the cable wall feedthrough is arranged surrounding a wall aperture of the wall. For example, the sealing device can be formed from a soft material, in particular a soft plastic material, for example TPE. In this case, the sealing device can be provided as a separate component which is arranged on the divisible frame, for example in the form of a sealing ring. Alternatively, the sealing device can be formed integrally with the divisible frame, for example integrally formed thereon, for example in the context of production by means of two-component injection molding. In contrast, the divisible frame is preferably formed from a hard material component, for example from a plastic, for example from polyamide, in particular glass-fibre-reinforced polyamide. Corresponding to the division of the divisible frame into a first frame component and a second frame component, the sealing device can be divided or divisible into a first sealing device component and a second sealing device component. In this case, the first sealing device component can be arranged separately on the first frame component or can be formed integrally on the first frame component. The second sealing device component can be arranged separately on the second frame component or can be formed integrally on the second frame component. In this case, the arrangement of the relevant sealing device component on the first and the second frame component can be provided identically or differently. As an alternative to a first sealing device component and a second sealing device component, an integral sealing device can be provided, which is arranged on the divisible frame.The divisible frame may have at least one fastening hole which is configured to receive a fastening means for fastening the divisible frame to a wall. The fastening means can be, for example, a screw, a nail, a rivet, a bolt and / or a clamping element. In this case, the fastening element is then guided through the fastening means through the fastening hole and connected to the wall, for example by screwing in (into a thread of the wall), driving in, adhering, pressing and / or clamping counter (for example by a screw nut, a rivet counter-element or the like, in particular after passing the fastening means through a corresponding cutout of the wall).Alternatively or in addition to a mounting hole, other means may be provided for mounting the divisible frame to a wall. Such agents are known per se in the art. For example, it can be provided to clamp the divisible frame in the wall aperture, clamp or press it against the wall by means of a counter element which is passed through the wall aperture, and / or to fasten the divisible frame by adhesive bonding, welding or soldering.It can be provided that only the first frame component is fastened to the wall, wherein then preferably the second frame component is fastened to the first frame component, for example by means of a snap connection, as described above.Alternatively, it can be provided that both the first frame component and the second frame component are fastened to the wall, wherein identical or different fastening methods can be provided here for the first frame component and the second frame component.In the cable wall feedthrough, it can be provided that the first frame component has one or more first fastening holes and that the second frame component has one or more second fastening holes. In this case, provision can be made (wherein this need not be the case in alternative configurations) for at least one of the one or more second fastening holes to be arranged congruently with one of the one or more first fastening holes in the assembled state of the divisible frame, in such a way that the at least one of the one or more second fastening holes and the relevant one of the one or more first fastening holes can accommodate the same fastening means for fastening the divisible frame to a wall. In the case of a screw as a fastening means, a screw is thus guided both through a (first) fastening hole of the first frame component and through a (second) fastening hole of the second frame component and connected to the wall (in particular screwed therein or secured by means of a nut), so that then the one screw (the one fastening means) presses both the first frame component and the second frame component against the wall. This may be provided for a plurality of pairs of first mounting holes and second mounting holes. In addition to one or more pairs of first fastening holes and second fastening holes which, in the assembled state, come into alignment with one another, the first frame component and / or the second frame component can have further fastening holes which do not come into alignment with a corresponding fastening hole of the respective other frame component. The fact that a first fastening hole and a second fastening hole are congruent does not assume, in the sense of the present disclosure, that they have the same cross section and / or that the cross sections completely overlap (this may be provided in embodiments). Instead, a congruence in the sense of the disclosure is to be understood as meaning that the relevant fastening holes overlap at least to such an extent that the same fastening means can be accommodated simultaneously in the relevant fastening holes.In connection with the above-explained congruent arrangement of first and second fastening holes in the mounted state, in particular a self-centering via conically tapering connecting elements, as described in detail above, can be provided in order to ensure that the congruentness of the relevant fastening holes results during the movement in the feed-through direction for connecting the second frame component to the first frame component.The cable wall feedthrough can have at least one grid component which is arranged in the divisible frame and is configured to subdivide the receiving space into a plurality of sub-receiving spaces. Each of the sub-receiving spaces can be configured to receive one or more sealing elements of the cable wall feedthrough, such that a guidance of cables received in a sealing element in each case through the receiving space in a feedthrough direction is made possible. The at least one grid component can be connected to the divisible frame in a releasable or non-releasable manner, in particular by insertion, or can be formed integrally with the divisible frame. For example, the grid component can be integrally formed on the first frame component and can be connected to the second frame component (connected in the assembled state) by means of corresponding connecting elements. A plurality of frame components can be provided, wherein each frame component can be connected to the divisible frame in a releasable or non-releasable manner or can be formed integrally with the divisible frame. In particular, embodiments can be provided in which the receiving space is firmly divided into a plurality of sub-receiving spaces by one or more grid components formed integrally with the divisible frame and can furthermore (optionally) be additionally divided into further sub-receiving spaces by one or more grid components which can be connected detachably or non-detachably to the divisible frame.Sealing elements can be arranged in the receiving space or the sub-receiving spaces in a manner known per se, wherein each sealing element is configured for sealingly receiving one or more cables. For example, one or more individual sealing elements can be provided, which is configured for the sealing reception of exactly one cable. For such individual sealing elements, for example from the document DE 10 2021 121 353 B3, designs are known which each have a passage for receiving a cable, wherein the individual sealing elements can be embodied in slotted fashion in order to be able to be laid around a respective cable. The receptacle of one or more individual sealing elements can then be provided for each receptacle space or the sub-receptacle space. Alternatively or additionally, an insertion component can be provided for arrangement in the receiving space or in a sub-receiving space, which is configured to receive one or more cables. An insertion component of this type is known, for example, from the document DE 20 2019 105 325 U1, wherein such a known insertion component has a relevant frame component made of a hard material component, which at least partially surrounds a component opening, as well as a membrane made of a soft material component, which covers the component opening, and a fastening device, which is configured to secure the frame component with the membrane to the cable wall feedthrough when the latter is inserted into a through opening (i.e. in the receiving space or in a sub-receiving space) of the cable wall feedthrough. In this case, the known insertion component forms an arrangement of cable receptacles which have cable receptacles arranged distributed over a surface of the membrane and which, in a cable insertion direction which runs transversely to the surface of the membrane, each have a through-membrane section arranged on the front side and a cable sleeve arranged on the rear side, which is designed to form a strain relief for an inserted cable. Alternatively, other known designs of individual sealing elements and / or plug-in components can be provided for the cable wall feedthrough according to the disclosure.The sealing elements can be inserted in the lead-through direction and / or transversely to the lead-through direction for accommodation in the accommodation space or in the relevant sub-accommodation space. In the case of an insertion transversely to the feed-through direction, it can be provided that the relevant sealing element is inserted before the connection of the second frame component to the first frame component and is secured to the frame by the connection of the second frame component to the first frame component, for example in that sections of the first frame component and / or of the second frame component are arranged relative to the relevant sealing element in such a way that a movement of the sealing element is restricted or prevented by means of form locking. When introduced into or along the feed-through direction, it can be provided that the relevant sealing element is introduced before or after the connection of the second frame component to the first frame component. In this case, it can be provided that the relevant sealing component is secured to the frame by connecting the second frame component to the first frame component, for example in that sections of the first frame component and / or of the second frame component are arranged relative to the relevant sealing element in such a way that a movement of the sealing element is restricted or prevented by means of positive locking.The cable wall feedthrough can have a covering component which is arranged and fixed on the divisible frame so as to at least partially cover the divisible frame. The covering component can thus be viewed as a ceiling or covering hood. The cover component can be formed as a divisible cover component having a first cover component and a second cover component, which can be connected by a movement in the feedthrough direction in order to form the cover component. In this regard, the embodiments explained above in connection with the divisible frame can be provided accordingly for the divisible covering component. Alternatively, for the divisible covering component, a connection of the first covering component and the second covering component by means of a movement transversely to the feedthrough direction can be provided. A corresponding embodiment of a cover component is known, for example, from document DE 10 2021 121 353 B3.The cover component can be arranged (mounted) on the divisible frame in a manner securing one, more or all sealing elements in the receiving space or in the relevant sub-receiving space. In particular, the receiving space or one, a plurality or all of the relevant sub-receiving spaces can be open to at least one side, in particular a side facing the covering component, when the cover element is not mounted, so that arranging in or removing a respective sealing element in the lead-through direction is made possible. In this case, the cover element can then, in the mounted state, at least partially cover the relevant at least one side of the receiving space or of the relevant sub-receiving spaces and thus at least one section of the relevant sealing elements and thus secure the sealing elements. A securing of sealing elements by the cover component can be provided alternatively or additionally to a securing by connecting the second frame component to the first frame component, as described above.For fixing the cover component to the divisible frame, corresponding connecting means can be provided, for example fastening means such as screws or elements of the cover component and of the divisible frame which form one or more relevant snap connections.In addition to the first frame component and the second frame component, the divisible frame can have further frame components which can be connected to the first frame component and / or the second frame component. As a result, a divisible frame can be adaptable (for example, scalable in size) for a given application by appropriate selection and combination of frame components. For further frame components, a connection can be provided in each case in the lead-through direction or transversely to the lead-through direction. One or more further frame members may be arranged between the first frame member and the second frame member. In this case, the second frame component is indirectly connected to the first frame component via the one or more further frame components.The embodiments explained above in connection with the cable wall feedthrough can be provided accordingly for the arrangement according to the disclosure for the feedthrough of cables through a wall.According to another aspect, a method of assembling a cable wall feedthrough for passing cables through a wall is provided. The method comprises providing a first frame component, providing a second frame component, and connecting the second frame component to the first frame component to form a divisible frame of a cable wall feedthrough. During the connection, the second frame component is brought up to the first frame component in a lead-through direction and connected to the first frame component by the movement in the lead-through direction. The method further includes accommodating at least one sealing element in an accommodation space of the cable wall passage surrounded by the divisible frame, arranging the divisible frame on a wall surrounding a wall passage of the wall, and accommodating at least one cable in the at least one sealing element and guiding the at least one cable in the passage direction through the accommodation space and the wall passage. Since an arrangement according to the disclosure can be created with the method for mounting a cable wall feedthrough, the method can also be understood as a method for producing an arrangement for passing cables through a wall. In the method, the steps thereof are not necessarily performed in the order mentioned above. In particular, it is possible to carry out the connection of the second frame component to the first frame component, the accommodation of the at least one sealing element in the accommodation space, the arrangement of the divisible frame on a wall and the accommodation of at least one cable in the at least one sealing element in any order and / or at least partially simultaneously. For example, in accordance with the above explanations with respect to the cable wall feedthrough, the at least one sealing element can be accommodated in an accommodation space surrounded by the divisible frame at least partially before the connection of the frame components, at least partially after the connection of the frame component or at least partially simultaneously with the connection of the frame components.In particular, when connecting the second frame component to the first frame component to form a divisible frame, the divisible frame can be formed so as to surround the at least one cable. Insofar as the arrangement of the at least one cable is understood as a substep of receiving the at least one cable in the at least one sealing element, the connection and the receiving in the at least one sealing element thus take place at least partially simultaneously.First, the first frame component can be arranged on the wall and then the second frame component can be connected to the first frame component by the movement in the lead-through direction to form the divisible frame, wherein the divisible frame is thereby arranged on the wall so as to surround the wall aperture at the same time.In the cable wall feedthrough according to the disclosure, the connection of the frame components in the feedthrough direction creates the possibility of initially fixing the first frame component to the wall and only subsequently completing the divisible frame and in this case enclosing the wall aperture and cables guided through it, wherein the desired position of the first frame component, which thus determines the position, is already secured to the wall. It is likewise possible to connect the frame components first, wherein cables can be passed through the divisible frame simultaneously or subsequently, and to arrange the joined divisible frame subsequently on the wall.Generally, the method may comprise the step of fixing the divisible frame to the wall - with fastening means or in another way, as described above with reference to embodiments of the cable wall feedthrough - wherein the fixing for the first frame component and the second frame component may be carried out separately or at least partially simultaneously. An at least partially simultaneous fixing of the first frame component and the second frame component is provided in particular if at least one second fastening hole of the second frame component is arranged congruently with at least one first fastening hole of the first frame component for receiving the same fastening means, since here both the first frame component and the second frame component are at least partially fixed by arranging the fastening means in the relevant first fastening hole and the relevant second fastening hole.The method may comprise the step of arranging and fixing a cover member to the divisible frame. In this regard, the embodiments described above in connection with the cover component can be provided accordingly. In particular, arranging and fixing a cover component to the divisible frame can comprise, as a substep, connecting a first cover component and a second cover component.In connection with the method for mounting a cable wall feedthrough, the embodiments explained above in connection with the cable wall feedthrough or the arrangement can also be provided accordingly.DESCRIPTION OF EMBODIMENTSFurther exemplary embodiments are explained in more detail below with reference to figures of a drawing. The following are shown here: FIG. 1 shows a schematic illustration of a divisible frame for a cable wall feedthrough; FIG. 2 is a schematic illustration of a divisible frame in the divided state; FIGS. 3A and 3B show schematic detailed representations of the divisible frame from FIG. 1 ; and FIG. 4 shows a schematic illustration of a first frame component of the divisible frame from FIG. 1 ; FIG. 5 shows a schematic illustration of a second frame component of the divisible frame from FIG. 1 ; FIG. 6 shows an arrangement of a cable wall feedthrough on a wall.FIG. 1 shows a divisible frame 1 for a cable wall feedthrough. The divisible frame is formed with a first frame member 2 and a second frame member 3 joined together into the divisible frame 1. The divisible frame surrounds a receiving space 4 for receiving one or more sealing elements which serve for the sealed guidance of cables. The receiving space 4 is divided by a grid component 5 in the embodiment shown into two sub-receiving spaces 6FIG. 2 shows a divisible frame 1 in the divided state. In the embodiment shown, the grid component 5 is formed integrally with the first frame component 2. The first frame component has, on an open side of the first frame component 2, first connecting elements 7, which are formed as dovetail-like projections. The second frame component 3 has second connecting elements 8, which are formed as recesses corresponding to the dovetail-like projections. For joining the frame components 2, 3 to form the divisible frame 1, the second frame component 3 is guided to the first frame component 2 in a lead-through direction 9 defined by the receiving space 4 for cables to be guided through the cable wall lead-through, such that the recesses of the second connecting elements 8 receive the projections of the first connecting elements 7, such that the relative movement between the first and second frame components 2, 3 is guided.The first frame member 2 has first attachment holes 10 and the second frame member 3 has second attachment holes 11. The fastening holes 10, 11 are designed as bores through which fastening elements, in particular screws, can be guided for fastening the divisible frame 1, which fastening elements can then be screwed to a wall in order to fasten the divisible frame 1 to the wall.As can be seen in the illustration of FIG. 1, the second fastening holes 11 of the second frame component 3 in the assembled state of the divisible frame 1 are arranged congruently with a respective first fastening hole 10 of the first frame component 2. Thus, a fastening member passed through a second fastening hole 11 not only fixes the divisible frame 1 to a wall but also fixes the second frame member 3 to the first frame member 2.In the embodiment shown, the first fastening elements 7 are designed to taper upwards. As a result, the projections of the first fastening elements 7 initially have a relatively large play when being introduced into the recesses of the second fastening elements 8, which play is reduced when the frame components 2, 3 are brought together further until the second frame component 3 is finally no longer movable transversely with respect to the lead-through direction 9. This self-centering assists simple assembly, in which it is ensured, among other things, that the second fastening holes 11 are arranged congruently with the corresponding first fastening holes 10.FIG. 3A shows a detailed illustration of the first frame component 2. FIG. 3B shows a detailed illustration of the second frame component 3. Here, the second snap elements 13 are arranged in the region of the second fastening holes 11. The first snap elements 12 are arranged in the region of the corresponding first fastening holes 10. When the frame components 2, 3 are connected, the first snap-in elements 12 snap into the second snap-in elements and thus form a snap-in connection, which secures the second frame component 3 to the first frame component 2. The securing of the second frame component 3 to the first frame component 2 provided with the snap connection is in addition to and independent of the securing means which provides a fastening element which is guided through a first fastening hole 10 and through a second fastening hole 11.FIG. 4 shows the first frame component 2 in an enlarged illustration. FIG. 5 shows the second frame component 3 in an enlarged illustration. It can be seen in FIGS. 4 and 5 that the first frame component 2 and the second frame component 3 have receiving recesses 14 for receiving further (separately formed) grid components 15, with which further sub-receiving spaces 6 can be formed.FIG. 6 shows a cable wall feedthrough arranged on a wall 100 above a wall aperture (not shown). In the cable wall feedthrough, the frame 1 divisible in FIG. 6 is arranged and fixed on the wall 100 surrounding the wall aperture. In this case, the divisible frame 1 cannot be seen in the illustration of FIG. 6, since it is concealed by a covering component 16 which is placed on the divisible frame and is secured thereto by means of screws. The cover component 16 is formed in two parts with two cover components 17 connected to one another in a separable manner. As can be seen in FIG. 6 on the left side of the cover component 16, the cover components 17 are connected by means of a snap connector, which brings about an assembly of the cover components 17 by bringing them together transversely to the lead-through direction 9. In alternative embodiments, it can be provided that the cover component 16 is formed by bringing the cover components 17 together in the feedthrough direction, as in the divisible frame 1.In the embodiment shown, the receiving space 4 is divided into four sub-receiving spaces 6 by means of a plurality of grid components 5. In each of the sub-receiving spaces 6, a sealing element 18 is arranged, which conducts a respective cable 101 (with a corresponding diameter) in a sealing manner. Here, the sealing members are inserted into the sub-accommodation spaces 6 in the lead-through direction 9, and are prevented from moving out of the sub-accommodation spaces 6 in the opposite direction by an inner edge portion of the cover member 16. Whereas in the embodiment shown only individual sealing elements are used which each guide exactly one cable 101 in a sealing manner, one or more of the individual sealing elements can be replaced by differently configured sealing elements, for example by an insert component with a pierceable membrane for guiding a variable number of cables 101. Blind plugs, i.e. sealing elements without a receiving opening for cables 101, can also be used in order to close off (optionally temporarily) sub-receiving spaces 6 not used for the cable feedthrough.On a side of the cable wall feedthrough facing the wall 100, a sealing device is provided. The seal is formed with sealing lips 19 which provide sealing device components and are each formed on the frame components 2, 3 and together form a sealing device which extends around the divisible frame 1 and provides a seal between the wall 100 and the side of the cable wall passage facing the wall 100.The cable wall feedthrough can be mounted as explained below. First, first frame component 2 is screwed onto a wall 100 having a wall opening through which cables 101 to be guided in a sealing manner pass, wherein only those first fastening holes 10 are used for this purpose, which do not coincide with a second fastening hole 11 in the assembled state. In this case, the first frame component 2 which is open on one side is placed around the cables 101 which run through the wall aperture. In the case of a grid component 5 already arranged in the first frame component 2, in particular in one piece, the cables 101 are already divided here into the already defined sub-receiving spaces 6. If additional sub-receiving spaces 6 are to be formed, the corresponding grid components 5 are inserted and the cables 101 are (further) distributed to the sub-receiving spaces 6. The slotted sealing elements 18 are placed around the cables 101 to be guided and subsequently inserted into the respective sub-receiving spaces 6 by sliding on the cables 101. Finally, the cover components 17 are brought together around the cables 101 to be guided and assembled together to form the cover component 16. The covering component 16 is guided along the cables 101 onto the divisible frame 1 and screwed firmly there.Alternatively or additionally, it can also be provided to place one or more sealing elements 18 around the cables 101 and to lead them into the relevant sub-receiving spaces 6 before the second frame component 3 is connected to the first frame component 2. In this case, a given sealing element 18 can also be inserted into the associated sub-receiving space 6 in a direction other than the feed-through direction 9, in particular transversely to the feed-through direction 9.It can likewise be provided in the various embodiments that the frame components 2, 3 of the divisible frame 1 are connected to one another so as to surround the cables 101 before one of the frame components 2, 3 is arranged and fixed to the wall 100.The cable wall feedthrough according to the disclosure thus ensures high flexibility during assembly, which in particular allows the assembly to be adapted to the circumstances of the individual case with respect to the desired cable feedthrough. In addition, it is thereby made possible to replace individual components, in particular of the divisible frame 1, without releasing the already existing connections at the ends of the cables 101 for this purpose. Removal and remounting of the cable wall feedthrough can take place around the cables 101.The features disclosed in the above description, the claims and the drawing can be important for the realization of the various embodiments both individually and in any combination.List of reference characters1 Divisible frame 2 First frame component 3 Second frame component 4 Accommodation space 5 Grid component 6 Sub-accommodation space 7 First connection elements 8 Second connection elements 9 Implementation direction 10 First fastening hole 11 Second fastening hole 12 First snap element 13 Second snap element 14 Accommodation recess 15 Grid component 16 Cover component 17 Cover component 18 Sealing element 19 Sealing lip 100 Wall 101 Cable
