    The invention relates to a media box for an arrangement for distributing gaseous and liquid media in a laboratory according to the preamble of claim 1.
    In building technology, ceiling structures are known to be used for the establishment of research laboratories such as chemical or physical research, in which the supply lines for exhaust air, supply air, the technical gases, liquids, power and data lines required in the laboratory, etc. within the ceilings are fastened directly to the corresponding building ceiling with the help of suitable fastening devices using dowels. Since the laying of the lines is usually carried out one after the other by different staff, the difficulty arises that the lines are sometimes not only criss-cross and alternately in several levels, but also afterwards due to the individual assembly of the fastening devices only very complex spatial changes can be made to an existing laboratory arrangement.
    From EP 1 934 414 B1 a ceiling construction for a laboratory room is known in which the gaseous and liquid media as well as electricity are routed in an orderly manner in parallel main supply lines in the area of the laboratory ceiling, which are held on a support frame made of profiled beams are. From the main supply lines, the various media are routed via flexible branch lines that can be connected to the supply lines via quick-release couplings to the respective media, which are accommodated above the laboratory tables at the corresponding workstations on the underside of the support frame.
    Although the ceiling construction described above offers a variety of advantages over conventional laboratory ceilings with a disorderly management of the media lines, this results in the problem that the supply of the respective jobs takes place exclusively via the hanging media columns, and the supply of media to the Fittings on the laboratory tables are not made via the tables themselves, but only via the lines hanging down from the media columns.
    DE 1857988 U1 describes an arrangement for supplying laboratory workstations with different media, which comprises a fixed, narrow wall element which is arranged between vertical profiles. In the wall element, the respective media, which are fed to the wall element within the profiles from the ceiling of the laboratory, are guided in parallel, superposed horizontal lines, from which branch pipes extend to the taps for the media located above the respective laboratory tables respective vertically extending support profiles are arranged in boxes on the back of the wall elements. Due to the construction with vertical standing profiles that extend from the floor of the room to the ceiling of the same, the arrangement described is complex to assemble and has little flexibility with regard to a subsequent positioning of the fittings and taps for outputting the media on the wall element.
    From the unpublished DE 10 2019 119 116 an arrangement for supplying liquid and / or gaseous media to workstations arranged in rows in a laboratory is known, the at least one standing modular wall element, which the media from in the area of the ceiling of the Laboratories running main supply lines are fed from via vertical feed lines. The wall element along which the workplaces are arranged in one row or two rows back to back and which can have a width of e.g. 100 mm or 200 mm and a height of e.g. 90 cm and a length of e.g. 90, 120, 150 and 180 cm, has a back on its upper side, on which one or more media boxes can be arranged, each of which has different removal fittings for the various media, via which they can be dispensed for use in the laboratory.
    The media boxes, the media are fed through horizontally running connecting lines guided within the wall element, for which each of the removal fittings of a media box is connected via a corresponding vertical connecting line to the associated horizontally running connecting line for the respective medium, which is located within the wall element of the respective media box extends in the downward direction. The document gives no indication of a modular structure of the media boxes.
    Accordingly, it is an object of the present invention to provide a media box for an arrangement described above, which allows a highly flexible adaptation to the provision of different media, and which can be in the shortest possible time and with little effort to output can be converted to other media and flexibly mounted in different positions on the back of the wall element.
    According to the invention, this object is achieved by a media box having the features of claim 1.
    Another object of the invention is to provide an arrangement which includes such a media box.
    According to the invention, this object is achieved by an arrangement having the features of claim 10.
    Further features of the invention are described in the subclaims.
    According to the invention, a media box for an arrangement for the supply of liquid and / or gaseous media, such as carbon dioxide, hydrogen or compressed air, to workstations arranged in rows in a laboratory comprises a housing with a base plate and a T-shaped support core, which extends in the vertical direction. The housing of the media box, which is mounted on a modular wall element of the arrangement, furthermore comprises at least two module elements which are detachably attached to the carrier core and which are located one above the other. The module elements, of which 5 are preferably arranged one above the other in the preferred embodiment, each consist of a carrier body with an L-shaped cross section, which can be releasably attached to the carrier core via engagement elements. According to the invention, the extraction fittings for the different media and, if necessary, other operating elements, such as rotary controls and display fields for the fittings that are used to provide the media, are arranged on the carrier bodies of the module elements.
    According to one idea underlying the invention, the engagement elements on the support core are designed as vertical grooves, and the engagement elements on each of the support bodies are designed as projections which engage in the vertical grooves of the support core. In this way, the module elements can be mounted on the T-shaped support core in a simple manner without the use of screws and detached from the latter with the aid of the blade of a simple screwdriver.
    According to a further idea on which the invention is based, the module elements can be clipped into the engagement elements arranged on the carrier core, which, as described above, are preferably designed as grooves. For this purpose, the carrier bodies of the module elements, which in particular consist of aluminum sheet, are slightly deformed and clipped directly into the groove-shaped engagement elements from the side. With this type of assembly, it must be ensured that the carrier bodies are only bent so much that the deformation is reversible and accordingly the module elements can be attached or detached several times. This has the advantage that individual module elements can also be exchanged independently of the other module elements if, for example, a different medium is to be output via a previously used media box after the laboratory workstations have been changed, or if one of the module elements is defective and needs to be replaced.
    Another possibility to assemble or disassemble the module elements is to place them on the carrier core from the side opposite the base plate and to introduce them into the engagement elements on the carrier core in the direction of the base plate.
    Furthermore, it is provided in the preferred embodiment of the invention that a closure plate for closing the top of the media box is arranged on the side opposite the base plate. For this purpose, the closure plate is preferably received with screws in axial threaded bores formed in the carrier core, which are formed in the end face of the carrier core, or else fastened to the carrier core with clip closures.
    For security reasons, it can also be provided that the module elements are arranged separately according to their function on the carrier core. Here, there is preferably a separation, often officially prescribed, spatial separation of electrical components and electrical lines from the fittings and lines carrying liquid and gaseous media by arranging them in different, separate spatial sections of the housing. This arrangement of the electrical components and the liquid-carrying components in spatially separate, hermetically separated spatial areas of the module elements can advantageously prevent the electrical components and lines from coming into contact with the water in the event of a possible leak in a water supply hose.
    Another possible division of the module elements could provide, for example, carbon dioxide, hydrogen, compressed air, vacuum and cooling water on one side of the T-shaped support body and electrical components such as sockets and network connections on the other side of the same.
    In larger laboratories it can also happen that a media box is to be used to supply two rows of workstations arranged head and head. In this case, according to a further idea on which the invention is based, it is possible for the media box to comprise a further T-shaped carrier core extending in the vertical direction. This further carrier core is preferably arranged adjacent to the first carrier core in such a way that the first and the further carrier core, when viewed from above, have a cruciform cross section. The further T-shaped carrier core also comprises at least two detachably fastened further module elements lying one above the other, each of which has a carrier body with an L-shaped cross section, which can be releasably fastened to the further carrier core via engagement elements. It is preferably provided that the first module elements and the further module elements - with the exception of the removal fittings and structural components which are individually fastened to the carrier bodies - are of identical design.
    Finally, according to a further idea underlying the invention comprises an arrangement for supplying liquid and / or gaseous media to workstations arranged in rows in a laboratory, on which the media box according to the invention can be mounted, at least one standing modular wall element, which the Media are supplied from main supply lines running in the area of the ceiling of the laboratory via vertical feed lines. The wall element along which the workplaces are arranged in one row or two rows back to back and which can have a width of e.g. 100 mm or 200 mm and a height of e.g. 90 cm and a length of e.g. 90, 120, 150 and 180 cm, has a back on its upper side on which one or more of the media boxes described above can be arranged and fastened, each of which preferably has different removal fittings for the various media, via which they can be dispensed for use in the laboratory.
    The media boxes are supplied to the media via horizontally running connecting lines guided within the wall element, for which each of the removal fittings of a media box is connected via a corresponding vertical connecting line to the associated horizontally running connecting line for the respective medium, which is located within the wall element extends downward from the respective media box.
    The arrangement according to the invention is characterized in that the media box or media boxes have a modular structure in the manner described above and can be releasably fixed in different positions on the back of the wall element. The vertical supply lines from the main supply lines routed in the area of the ceiling of the laboratory are advantageously routed within a console which extends in the vertical direction from the ceiling of the laboratory down to the back of the wall element. The media boxes are preferably freely displaceable on the back of the wall element (s), which advantageously enables them to be placed on the tables in positions where the removal fittings are freely accessible from the front after further laboratory devices have been set up and are not covered by the newly installed devices.
    Here, the vertically extending lines at the upper end of the console are preferably fixed by so-called bulkhead screw connections on this and protrude at the lower end of the same up to the intended horizontal installation height of each medium out of this. The bracket, which is cuboid in shape, is preferably manufactured as a unit at the factory and is simply placed on the wall element at a desired position during assembly and mechanically connected to it, e.g. by means of screws. Alternatively or at the same time, however, the console can be attached to this wall in the case of single-row workstations in which the modular wall element is set up on a wall of a laboratory room. Alternatively, in the case of two-row workstations that are separated by wall elements set up freely between them, the console can be hung on a support frame or on the ceiling of the laboratory room, which enables particularly time-saving and stable installation.
    The vertical feed lines guided within the console, which extend into the interior of the wall element at the lower end of the console, advantageously have first self-closing T-shaped connection adapters at their lower ends. In a similar way, the free ends of the vertical connection lines, which are led from the media boxes from above into the interior of the wall element, are preferably each provided with a second T-shaped connection. This is preferably designed as a known T-shaped screwed pipe connection, which is connected, for example, via a conical crimped connection to the respective ends of the horizontally running connecting line and to the free ends of the second vertical connection lines, which lead to the respective removal fittings of the media boxes.
    At the T-shaped connections of the media boxes furthest away from the console, the open outlets of the T-shaped connections can be closed in this embodiment by known end caps, which are also placed on the outlets by means of a compression fitting and seal them metallically close. The use of T-shaped pipe screw connections results in the advantage that the modular wall element can be expanded in a simple and inexpensive manner to include additional media boxes, or a number of wall elements can be expanded by a subsequently added additional wall element. To do this, all that needs to be done is to attach the additional wall element to the floor without cables and to equip it with another media box. Subsequently, preferably only the horizontally running connecting lines for the media to be output in the further media box are cut to length, the end caps on the pipe screw connections of the last media box are removed and the free ends of the further horizontal media lines are inserted into the associated free outlets and using the compression fittings connected.
    Alternatively, according to a further, more expensive embodiment of the invention, the second T-shaped connections can also be designed as self-closing T-shaped connection adapters, which in the latter case are preferably identical to the first T-shaped connection adapters and the respective Seal the outlets in a liquid-tight manner if no other complementary adapters are connected.
    In order to obtain a flow line connection between the respective removal fittings of the media boxes and the connecting lines running horizontally inside the wall element, preferably with a double S-stroke, the latter have a complementary connection adapter at one end, which is preferably tool-free can be attached in the manner of a quick-release coupling or, in the case of highly pure gases, can be screwed on to form a metallic seal. The connection of the vertical first supply lines with the media boxes on the right and left side of the console is preferably done by plugging the respective complementary connection adapter of the horizontally running connection lines onto the self-closing outlets on the right and left side of the first self-closing T-shaped connection adapter below the console. The described self-closing T-shaped connection adapters are known from the prior art and are produced, for example, by the applicant.
    Insofar as horizontally running connecting lines are used in the context of the present application, this is used exclusively to distinguish the lines from the lines guided within the console and the vertical connection lines to the media boxes, and also includes lines that are not straight , but eg in a vertically extending plane in an arc, S-shape or double S-shape.
    The arrangement described has the advantage that the space between two rows of head-to-head laboratory workbenches is effective for distributing the liquid and gaseous media and electricity supplied via the main supply lines in the ceiling of the laboratory room can be used without having to provide individually manufactured and therefore expensive laboratory furniture in which the lines are laid individually in order to conduct the respective media to the associated connection fittings in the respective laboratory workbenches.
    The use of self-closing first T-shaped connection adapters at the lower ends of the vertical feed lines guided in the console has the further advantage that the console is positioned at any point on the modular wall element and the media in question are plugged into the complementary connection adapter the horizontally running connection lines can be routed extremely flexibly to media boxes on the right and / or left side of the console. Furthermore, in the event of a leak, the branch in question can be disconnected and shut down in the shortest possible time by pulling off the complementary connection adapter, without the need for expensive shut-off valves in the wall element or console, which take up additional space and cause costs.
    Another advantage of the arrangement is that the media boxes, in which the removal fittings for the respective media are included, can be moved to another position on the back of the wall element within a very short time and with little effort to supply affected workplaces with the desired media after a reconstruction of the laboratory. A particular advantage of the arrangement is that the previously laid, straight or curved, S-shaped or double S-shaped supply lines in the wall element due to the use of self-closing first T-shaped connection adapters at the lower ends of the vertical Supply lines guided within the console can be released without the medium escaping. Due to the preferred routing of the lines with a double S-hinge, the media boxes according to the invention can also be easily shifted by approx. + -50 cm on the horizontal support of the wall module if required. This has the advantage that the media boxes can be positioned at a different location within a very short time, at which they are not covered by other laboratory devices if these are subsequently placed on one of the laboratory tables.
    The modular wall element, which can have a length of 90, 120, 150 or 180cm or a specific length, for example, is preferably made up of known structural profiles with longitudinal grooves arranged therein, for example aluminum extruded profiles, which are connected via fasteners inserted into the grooves are connected to each other in a known manner to a cuboid support structure fetch inside, on the outside of which large-area plate-shaped front and rear panels are preferably detachably fastened without tools via connecting elements engaging in the grooves. The cladding can for example consist of wood or also of sheet metal or plastic and can alternatively be attached to the profiles of the cuboid support structure via hinges or permanent magnets arranged on their inside or in some other known way without tools. This opens up the possibility that the horizontally running connecting lines laid in the interior of the cuboid support structure are freely accessible from the outside in a very short time, for example in order to add further media and their lines.
    In order to close the openings arising on the top on the back of the wall element after relocating the media boxes, or to provide such openings for inserting the media boxes with the vertical connection lines connected to them, it is a further idea underlying the invention provided that plate-shaped cover elements are arranged on the back of the wall element, ie preferably on the upper two longitudinal profiles of the cuboid support structure, which can be releasably attached to the wall element to close the openings in the area of the back of the wall element. The cover elements can be made of plastic, wood or metal, for example, and can also be fixed on the top of the back using permanent magnets, so that they can be removed from the top of the cuboid support structure without the use of a tool, or in a different position on it can be positioned. The covers are preferably designed in lengths of 10, 15 and 30 cm and thus, in a particularly advantageous manner, allow the media boxes to be moved in 5 cm steps without cutting new special covers. The openings created by moving the media boxes in steps of e.g. 5 cm on the top of the back are closed in a particularly sustainable way by moving the adjacent cover elements accordingly, without the cover elements having to be separated for this purpose.
    As an alternative to a magnetic attachment, the cover elements can also have elastically deformable engagement elements, for example two or more laterally protruding arms made of an elastic material, which can engage with their hook-shaped ends in the grooves of the profile strips to fix the cover elements on the profile strips to be brought into engagement with these in the manner of a clip connection.
    Furthermore, it can be provided that the first self-closing connection adapters are arranged offset from one another at the lower ends of the vertically running supply lines, viewed in the vertical direction. The distance between the first self-closing connection adapters arranged at different heights can be, for example, the height of an inserted T-shaped connection adapter for the respective medium, so that sufficient space is created for each of the first self-closing connection adapters at the lower ends of the vertically running supply lines to connect the first self-closing T-shaped connection adapter with the complementary connection adapters and to guide the lines overall without crossing.
    In the same way, in the preferred embodiment of the arrangement, the T-shaped screw connections at the lower ends of the vertical connecting lines, which arise at the removal fittings of the media boxes, viewed in the vertical direction, are each arranged at a distance from one another, in such a way that that the horizontally running connecting lines for the respective liquid and gaseous media can be guided in planes running parallel to one another within the wall element. Through this embodiment, in connection with a straight or curved or S-shaped line routing within the wall element, a particularly structured arrangement of the lines is obtained, which in the case of an exchange or an extension of the wall element by a preferably identical additional one arranged, for example, on the end face of the wall element Wall element enables a particularly simple and quick installation of the same.
    According to a further idea on which the invention is based, it can alternatively be provided, as already stated above, to manufacture one or more of the horizontally extending connecting lines from a flexible material and to double them within the wall element along an arched, S-shaped or double S-shaped line path to lead. This opens up the possibility, starting from an initially central position of a media box, in which the horizontally running connecting lines are laid along a simple S-shaped line path, for example, to put this media box on its back by + -50cm in both directions with very little effort of the wall element can be displaced, which leads to the fact that the curved or simply S-shaped line path is stretched to a straight line path, or is compressed to a double S-shaped line path.
    This further increases the flexibility in setting up the laboratory workstations and advantageously reduces the time required to move the media boxes onto the back of the wall element, since no lines have to be lengthened or shortened. There is also the advantage that the media boxes can also be moved by untrained personnel, since no line connections have to be opened or reconnected.
    In the case of pressure lines, such as those used for the distribution of the gases and liquids used in a laboratory, such as argon, helium, propane or water and compressed air, a previously described arcuate, S-shaped or double-S -shaped line path, these can be designed in particular as soft copper pipes, steel flex lines or plastic hoses. At the same time or alternatively, the vertical connection lines can also be designed as flexible lines with a curved or S-shaped line path in the manner described above in order to enable the media boxes to be shifted along the back by a certain distance of e.g. 20 cm to the right or left, without the horizontally running connecting lines for the respective media within the wall element having to be replaced by shorter or longer lines.
    In the preferred embodiment of the arrangement, in addition to the vertical feed lines and horizontal connecting lines for the liquid and gaseous media in the console, a vertically extending round cable in the wall element can be guided to a flat ribbon cable extending horizontally in the wall element. The electrical connection from the round cable to the ribbon cable takes place in an extremely space-saving manner with an electrical connection element in which pointed screws are screwed into the connection of the conductors through the insulation. In the same, reverse manner, the connection is made from the horizontal ribbon cable to round cables, which are used, for example, to supply electrical components in the module elements of the media boxes, which preferably have one or more power sockets and, if necessary, other electrical components such as FI fuses and transformers Supply of USB ports etc. can contain.
    A particular advantage of the method described above for the flexible connection of electrical components that are included in the module elements of the media boxes is to be seen in the fact that further electrical components, or even complete electrical module elements, which are subsequently can also be referred to as electrical modules, or other electrical under-table installations can be connected.
    In the preferred embodiment of the arrangement, the second multi-core electrical line is designed as a flat ribbon cable, which has a rectangular cross section with electrical wires running parallel to one another, which are surrounded by an elastic insulation material, for example plastic. The parallel electrical wires run along a longitudinal plane, which in turn extends parallel to the flat side of the electrical line. In this embodiment, the electrical connecting element has a number of mandrel-like contact pins that are assigned to the number of electrically conductive cores and are arranged in parallel next to one another, which are used to establish an electrically conductive connection in a direction perpendicular to the longitudinal plane in the direction of the parallel cores guided in the longitudinal plane a sufficiently large force can be applied to pierce the elastic electrical insulation material. This has the advantage that the multi-core electrical line can be installed horizontally within the wall element and / or the console, and a desired electrical connection to the electrical connection lines of the media boxes and / or to another horizontally running, multi-core electrical line configured in the same way can be produced, e.g. B. to expand the row of workstations with another modular wall element.
    According to a particularly advantageous embodiment of this embodiment, the first, in the console from the ceiling of the laboratory downward electrical vertical supply line arranged within the wall element, and extending in the horizontal direction angled portion on which the electrical connecting element is mounted, which carries the spike-like, spike-like contact pins assigned to the respective wires, which penetrate the electrical insulation of the second horizontal electrical line to produce the desired electrical connection between the wires of the first vertical electrical line and the wires of the second horizontally extending electrical line. This flat and angled embodiment of the end of the first vertical electrical supply line has the advantage that it can be transferred very easily in an arc from the vertical to the horizontal without the risk of a cable break.
    In the case of data lines that are used to supply the respective workplaces with network access, it is provided according to a further advantageous embodiment of the invention to install an active microswitch centrally at the lower end of the console, which has four outputs, and at least to provide a further microswitch with four outputs for a module element of each media box, which have a patch cable, for example, 3m long. The patch cables from the media boxes can thus simply be plugged into the central microswitch below the console. This embodiment of the invention has the advantage that all connected media boxes can be provided with several network sockets despite the tight space conditions when using very narrow wall elements with a width of, for example, only 100 mm Media box or the wall element must be connected in a star shape to the central switch via a separate network cable, which is not possible or only possible with great effort for reasons of space with the mentioned depth of the wall element.
    The invention is described below with reference to the drawings using preferred embodiments. The drawings show: FIG. 1 a schematic spatial representation of the arrangement according to the invention with three media boxes, FIG. 2 a schematic, semi-transparent front view of the arrangement according to the invention with three media boxes mounted on the back of the modular wall element (s), FIG. 3 a schematic exploded view of a preferred embodiment of the modular media box according to the invention, FIG. 4 a schematic exploded view of a preferred embodiment of the modular media box according to the invention, which comprises a further carrier core, and FIG are shown.
    Fig. 1 shows an arrangement 1 for supplying liquid and / or gaseous media 2 to workplaces 4 in a laboratory, which are arranged side by side in a known manner in rows. The media 2 are here supplied from main supply lines 6 routed in the area of the ceiling of the laboratory via vertically routed supply lines 8 to at least one standing modular wall element 10, which extends along a row of workstations 4. As shown, the work tables of the workplaces 4 are preferably placed head-to-head with their backs against the front and back of the wall element 10, which has a back 12 on its upper side, on which, as shown, media boxes 100 according to the number of workplaces are arranged in the row. Each of the media boxes 100 has a large number of removal fittings 16, such as self-closing fittings, plug sockets and taps for the respective technical gases, liquids and compressed air that are required at the respective workstations 4. The media boxes 100 can, for example, have a width of 300 mm, a depth of 100 mm and a height of 300 mm and can be individually equipped with the desired removal fittings 16 and prefabricated as independently manageable units.
    As can be seen from the semi-transparent representation of FIG. 2, the respective media 2 are supplied to the extraction fittings 16 via horizontally extending connecting lines 18 which are guided within the wall element 10 and which are guided along an S-shaped path, each Withdrawal fitting 16 of a media box 100 is connected via a vertical connection line 20 to the associated horizontally running connection line 18 for the respective medium 2, which extends downward within the wall element 10 from the media box 100.
    The media boxes 100 can be positioned and fixed on the back 12 of the wall element 10 in different positions, for which each wall element 10 has a support structure with two profile strips 10a, 10b running parallel to one another, which are located between two unspecified, vertically standing posts the front and back of the modular wall element 10 extend. The media boxes 100 have at least one base plate 102 and are fixed on the profile strips 10a, 10b, preferably with the aid of engagement elements received on the base plate 102, preferably snapped on or fastened with the aid of slot nuts and screws.
    In order to close the openings 11 remaining between them in the area of the back 12 after the assembly of the media boxes 100, one opening of which is indicated, for example, in FIG of the wall element 10 are snapped on and are slidably supported on this. For this purpose, the plate-shaped cover elements 32 have engagement elements 32a on their underside, which are designed to be resilient and engage in grooves or depressions, not shown in detail, in the profile strips 10a, 10b, or engage underneath them in a form-fitting manner on their underside.
    As can also be seen from the representations of FIGS. 1 and 2, the vertical supply lines 8 are guided in a bracket 22 which extends from the ceiling of the laboratory down to the back 12 of the wall element 10. The vertical feed lines 8 are led out of the bracket 22 with their lower free ends 8u and extend into the interior of the wall element 10 after the assembly 1 has been installed. The vertical feed lines 8 have at their free lower ends 8u first self-closing T-shaped connection adapters 26, which are arranged on different levels for the respective media 2 as shown in FIG.
    In the same way, the free ends 20u of the vertical connection lines 20, which lead to the media boxes 100, each have a T-shaped connection 28 for each medium 2, these second T-shaped connections 28 at a distance from one another in different planes are arranged, which correspond to the planes in which the first self-closing connection adapters 26 are arranged. The positioning of the first self-closing T-shaped connection adapter 26 as well as the second T-shaped connections, which are designed as compression fittings, is preferably carried out in such a way that the adapters 26 and connections 28 are each arranged in a horizontal plane and in the depth direction of the wall element 10 lie in pairs in spaced-apart vertical planes running parallel to one another, in which the S-shaped line paths of the connecting lines 18 then also run.
    In order to establish a flow connection between the first self-closing T-shaped connection adapters 26 and the second T-shaped connections 28 for each medium 2, the associated horizontally extending connecting lines 18 in the wall element 10 have at their ends below the console 22, respectively a complementary connection adapter 30, which can be inserted into the self-closing outlets of the first T-shaped connection adapter 26 for the respective medium 2 in order to establish a flow connection.
    As can also be seen from Fig. 2, in the preferred embodiment of the invention, in addition to the vertical feed lines 8 and horizontal connecting lines 18 for the liquid and gaseous media in the console 22, a vertically extending first multi-core electrical line 40 and in Wall element 10 is guided by a second horizontally running multi-core line 42, which is electrically conductively connected to this, for supplying electrical current, to which at least one electrical module 44 is connected. This can have at least one, but preferably a large number of power sockets and possibly further electrical components such as transformers and fuses. As can be seen from the media box 100 on the right-hand side of FIG. 2, the electrical module is connected via a multi-core electrical connection line 46 running in the vertical direction within the wall element 10 to the second horizontally running multi-core electrical line 42 via an electrical connection element 48 connected, the spike-like, the respective wires assigned contact pins 50, which penetrate the insulation of the respective wires of the second horizontally extending multi-wire electrical line 42 after placing the electrical connection element 48 and contact the associated, inside guided electrical wire, which with a associated electrical phase, or the neutral conductor and the protective conductor of an electrical power supply network are connected. The contact pins 50 can for this purpose in particular be designed as sharpened screw pins which have an external thread (not shown in more detail) that interacts with an internal thread fixed to the housing in such a way that the contact pins after the electrical connection element 48 has been fitted through the external insulation of the relevant wire of the multi-wire electrical line the live wire can be screwed in.

These can be passed through an associated opening in the closure plate 103 and engage with their thread in an axial threaded bore, not designated in more detail, which is formed in the end face of the carrier core 104.
    The module elements 106 are preferably arranged separately according to their function on the carrier core 104, the electrical components and electrical lines as well as the fittings and lines carrying the liquid and gaseous media taking place in different spatial sections of the housing 101, which are separated by a wall 105 of the carrier core 104 are separated from each other. In the illustration of FIG. 3, media such as carbon dioxide, hydrogen, compressed air, vacuum and cooling water are arranged on the left-hand side of the T-shaped carrier core 104, while sockets and network connections are located on the right-hand side.
    Another embodiment of the media box 100 according to the invention is shown in FIG. This comprises a further T-shaped, vertically extending carrier core 104 ', which is arranged opposite the first carrier core 104 in such a way that the first and further carrier cores 104, 104' have a cruciform cross-section when viewed from above. Furthermore, the further T-shaped carrier core 104 'also comprises a plurality of module elements 106 lying one above the other, each having a carrier body 108 with an L-shaped cross section, which can be releasably attached to the further carrier core 104' via engagement elements 110, 112.
    As can be seen from the illustration in FIG. 5, the media box 100 on the underside of the base plate 102 has further web-shaped engaging elements 114 which, after the media box 100 has been placed, from above into the two parallel profile strips 10a, 10b of the Engage the back 12 of the wall element 10 and thereby fix the media box 100 on the back 12. In order to reliably fix the media box 100 afterwards, it can additionally be provided that the base plate 102 is fixed to the profile strips 10a, 10b via one or more screws, which are passed through associated openings in the base plate 102 and in slot nuts (not shown in detail) in FIG engage the upper longitudinal grooves of the profile strips 10a, 10b. As can also be seen from the illustration in FIG. 5, the vertical connection lines 20 are arranged offset at different distances from the front side of the L-shaped support bodies 108.1 to 108.5. Here, the connection line 20 for supplying the lowest module element 106.1 closest to the base plate 102 has the smallest distance from the front of the L-shaped support body 108.1, whereas the connection line 20 for the uppermost module element 106.5 of the media box 100 has the greatest distance.
