Abstract:
The invention relates to a base plate ( 2 ) in a cable distribution cabinet. The base plate ( 2 ) is divided into two. The rear half ( 2   a ) can be folded down and the other half ( 2   b ) can also be inserted from the direction of the lower base chamber ( 3 ). The base plate ( 2 ) is sealed from the cables ( 15 ) with the help of sealing blocks ( 5 ) of a closed-cell foam and not by means of rubber grommets. The sealing blocks ( 5 ) have a height of several centimeters and, with that, a high sealing length. Any shifting of the sealing blocks ( 5 ) is prevented by threading them on guide rods ( 14 ).

     TECHNICAL FIELD 
     The invention relates to a bottom plate, as is arranged in particular in cable distribution cabinets between the distribution compartment and the pedestal compartment as a partition, but can also be used in other electrical switchgear cabinets. 
     BACKGROUND 
     Cable distribution cabinets are used, for example, in telecommunications technology to connect a large number of domestic service connections to the underground cables. 
     For this purpose, the housing of the switchgear cabinet in which the distribution compartment with the clamping rails or further active electrical components is located, is positioned on a hollow pedestal, which extends at least partially into the ground and through which the underground cables are passed. 
     For reasons of protection against electric shock, the formation of condensation water etc., a bottom plate is arranged as a partition between the distribution compartment and the pedestal compartment, i.e. between the actual cabinet housing and the pedestal, and the underground cables extend upwards into the distribution compartment through said bottom plate. 
     A number of problem cases need to be taken into consideration here. 
     Firstly, when viewed in plan view, a fitting rack is usually fitted in the housing, and this fitting rack ensures the stability of the housing, and the individual components, in particular the blocks with the terminal strips, are screwed on the fitting rack. 
     When viewed in plan view, these blocks with terminal strips are located in the front region, approximately in the front half, of the basic outline of the housing. The underground cables should therefore pass through the bottom plate preferably in the rear region in order to be passed up from there behind the terminal strips to the required height. 
     Theoretically, the underground cables could also pass through the bottom plate in the front region, but in this case they would have to be bent back towards the rear below the lowermost terminal strip. As regards the thickness of the underground cables of usually more than 4 cm and the corresponding rigidity, this is in principle difficult, but is even more difficult, in view of the tight installation conditions, the further towards the bottom on the fitting rack the terminal strips begin because there is less space remaining for a deflection towards the rear between the cable passage in the bottom plate and the lowermost terminal rail. 
     Another problem is the damage to switchgear cabinets owing to motor vehicles being driven into them. 
     In this case, the outer protective paneling of the switchgear cabinet is often damaged, and this can be replaced relatively easily. 
     If, however, the frame and/or the bottom plate is also broken and needs to be replaced, the complexity involved is very great since the individual underground cables pass through this bottom plate through cable passages and therefore all of the underground cables need to be disconnected prior to the replacement and the switchgear cabinet needs to be lifted off from the pedestal before a new bottom plate can be fitted on the pedestal. 
     This also results in a long downtime of all of the domestic service connections suspended on this switchgear cabinet. 
     A further complicating factor is the fact that the housing usually comprises an inner frame, which is composed of profiles along the edges and onto which the outer paneling of the housing is applied, and this inner frame often reaches down beyond the boundary between the distribution compartment and the pedestal region and merely has horizontal transverse struts at the boundary, on which struts the bottom plate can be fastened. 
     SUMMARY 
     The object in accordance with the invention is therefore to provide a bottom plate which, despite simple and inexpensive manufacture with good utilization of the distribution compartment, allows a large number of cables to be passed through and can nevertheless be fitted simply and quickly even in the event of damage and extension. 
     As a result of the fact that the at least one plate part of the bottom plate is fastened on the outer edge of said bottom plate in such a way that it can be folded with respect to the frame, this half does not need to be completely removed, but can be brought out of engagement with the cables being passed upwards by means of being folded away. 
     In addition, this plate part can also be completely removed. For this purpose, either the hinge which enables the folding process is a disconnectable hinge, or the fastening of this plate part to the frame can be released. 
     The other plate part with respect to the foldable plate part is preferably only removed and is not configured so as to be foldable, but can alternatively likewise additionally be foldable. 
     An important factor here is the fact that the folding mechanism is designed in such a way that the foldable plate part can be folded away downwards into the pedestal region. 
     Even in the case of the other plate part which can be dismantled, the fastening together with the dimensioning of the plate part should be selected in such a way that this plate part is only removed downwards, into the pedestal region, during dismantling. 
     During the fitting and dismantling process, these plate parts thus do not need to enter the distribution compartment, i.e. the compartment above the bottom plate, and the internals provided there do not need to be deactivated or disconnected. 
     The fastening of the plate parts on the frame takes place by means of locking elements which are as simple as possible and as quick to operate as possible, in particular quick-release closures, such as quick-release lever-type closures, which only require a quarter rotation for locking. 
     In the central region of the bottom plate, an opening is provided which extends beyond the separating line between the two plate parts, through which the cables run upwards. 
     In this case, the moisture sealing against the ingress of moisture upwards into the distribution cabinet is avoided as a result of the fact that cable bushings made from rubber material in the form of thin flat material with a thickness of from 1 mm to 3 mm are not used, as is conventional, but the opening around the cables is closed with the aid of sealing blocks made from an elastic material, in particular foamed material, which have a sealing length, i.e. measured in the vertical cable running direction at this point, of at least 30 mm, preferably at least 50 mm, preferably at least 70 mm. 
     These sealing blocks preferably comprise a closed-cell foamed material, i.e. a foamed plastic, in order to prevent the ingress of water into the individual pores and the forced advancement on this path. 
     The cable passages are precut into the sealing blocks, but the parts falling out in the process which provide the cable passage are not completely removed, but the necessary ring-shaped cuts still have interruptions as the joints. In this way, primarily a plurality of concentric almost finished ring-shaped cuts for different cable diameters can be produced. During fitting, the required ring-shaped cut is then finished and the corresponding core element removed. 
     In this case, the ring-shaped cuts do not run vertically, i.e. at a right angle with respect to the upper side and lower side of the sealing block, but are slightly inclined with respect thereto and form a truncated cone, which has its smallest diameter at the upper end. 
     Since the material is elastic, even when a neck diameter at the upper end of the truncated cone is selected to be too narrow, the material there is expanded so far outwards by means of compression that it allows the cable to pass through and seals said cable off particularly well as a result of this prestress. 
     The moisture approaching from below will have to overcome an ever greater resistance as it rises further upwards as a result of this increasing prestress and will therefore ultimately not be able to pass into the distribution compartment. The cone angle is in this case between 1° and 10°, preferably between 2° and 7°. 
     The ring-shaped cuts additionally have an access cut, which reaches from the freely accessible edge of the sealing block up to the ring-shaped cut and along which the sealing block can be folded apart in order to be able to push it from the side onto the already fitted cable. 
     In order to further facilitate fitting, the sealing blocks are separated in the longitudinal direction and the cable passages are either accommodated completely in one of the two block parts—with an access cut towards the contact face to the other block part—or they lie centrally on the separating line, with the result that no access cut is required. 
     In each case one of the two associated halves of a sealing block then bears with its rear side facing away from the contact face against a longitudinal edge of the opening in the bottom plate, i.e. against one of the two plate parts. 
     In order to safely press the block parts against one another in the fitted state and also to avoid a lateral displacement, the separating line between the block parts is not a straight separating line, but has protrusions in one and/or another transverse direction, and the other block part has a corresponding cut-out. Preferably, the separating line has a zig-zag configuration when viewed in plan view, and the two block parts are preferably identical in terms of configuration. 
     In order that, in the fitted state, the two sealing blocks remain safely between the two halves of the bottom plate around the cables, they are plugged onto guide bars. 
     These guide bars run from the longitudinal edge of the opening on one plate part, in particular the foldable plate part, in the transverse direction into the opening, to be precise in the plate plane or slightly offset parallel with respect to the plate plane, and beyond the separating line and also beyond the opposite longitudinal edge of the opening, below the other plate part. 
     These guide bars are arranged distributed at regular intervals over the longitudinal extent, and corresponding through-openings running in the transverse direction for plugging-on as guide opening are arranged in the sealing blocks at an identical interval. 
     Preferably, in each case one guide opening is provided in each sealing block laterally close to the end. The length of the opening in the bottom plate is filled precisely by a specific number of sealing blocks, the intention being for the totality of the sealing blocks to have an overdimension in comparison with the opening in the bottom plate both in a longitudinal direction and in a transverse direction in order to achieve the desired prestress in the fitted state. The number of guide bars is therefore preferably double the number of sealing blocks. 
     In order to have secure bearing of the sealing blocks available in the transverse direction, the longitudinal edge of the opening is in each case in the form of a vertically running stop face on the plate parts, the height of said stop face corresponding at least to the height of the sealing blocks and preferably having a bend, which protrudes into the opening, for resting the ends of the sealing blocks at the lower end. 
     The guide bars are fitted at approximately half the height of this stop face. 
     In order to subject the sealing blocks sufficiently to prestress in the transverse direction, this is preferably not brought about by the use of the second plate part alone, but by a press strip, which can be prestressed in the transverse direction, presses against the longitudinal edge of the sealing blocks which faces the second plate part and extends over the entire length of the opening. 
     This press strip is fastened displaceably on the non-foldable plate part, in particular the front plate part, by means of longitudinal slots, and the free ends of the guide bars, on which an external thread is applied, pass though said press strip. 
     As a result, the press strip can be prestressed against the sealing blocks by means of threaded closures fitted on these free ends (behind the press strip). 
     With such a bottom plate, problem cases such as repair work and extensions of cable distribution cabinets can also be realized easily. 
     In the case of repair work, the supporting frame often also needs to be removed in addition to the outer housing, i.e. the cladding, owing to damage. 
     Since an already existing bottom plate, even if it is not itself damaged and does not itself need to be replaced, is fastened on the transverse struts of the frame, first this bottom plate needs to be removed before the frame is replaced. Then, the frame is detached from the pedestal and the internals or the mounting rack supporting said internals and lifted off upwards and a new frame is positioned. 
     Then, the undamaged old or replaced new bottom plate in the two-part foldable physical form according to the invention is fitted relatively easily by the rear, foldable plate part first being fastened on the frame in the as yet unclad pedestal region below the fitting plane of the bottom plate. 
     Then, the first, i.e. the rear row, of block parts is pushed onto the guide bars of the folded-down plate part over the entire length of the opening in this plate part onto the guide bars and, in advance, the corresponding cable passages in these sealing blocks are already opened corresponding to the diameter and the position of the cables extending upwards through the pedestal region. 
     Then, this plate part is folded up into the activated horizontal position and, in the process, the cables are introduced through the access cut into their respective cable passage of the corresponding block part, and the rear plate part is fixed in this folded-up position. 
     Now, the second, front halves of the block parts are pushed onto the guide bars of the rear plate part once, in turn, the cable passages for the cables which are further forward therein have been opened at the corresponding points and with the appropriate diameters, which cables in the process pass through the access cuts into their cable passages. 
     Then, the second plate part is brought from below through the pedestal region from the front against the block parts until it has been raised up as far as the fitting plane of the bottom plate, and is fixed with respect to the frame. 
     In order to press the sealing blocks tightly against the outer circumference of the cables, a press strip, which extends over the entire length of the opening and has a vertical limb which extends downwards from the front plate part, is pressed against the end face of the second row of blocks with the aid of the free end of the guide bars, which is passed through and is equipped with an outer thread, on which guide bars the rotary closures are fitted. 
     Usually even more complex than repair work is the extension of an existing cable distribution cabinet if further internals no longer have room in the previous cabinet. 
     Depending on the age of the cable distribution cabinet, the model in question is one with a frame supporting the housing, or else one without such a frame, in which only a mounting rack for supporting the internals is provided. 
     Likewise, a bottom plate may be provided in the existing cabinet, or not. 
     In any case, as was described above in relation to repair work, first the housing, i.e. the external cladding and possibly the internal frame, needs to be removed. 
     Since a relatively wide pedestal is also required for the extension work, i.e. generally widening work, on the housing, the pedestal also needs to be replaced. 
     In order that it is not necessary for the internals to be removed and disconnected, they need to be suspended on an auxiliary apparatus in order to remove the pedestal. Then, the supporting pedestal is removed and a new, wider pedestal is fitted underneath, on which the mounting rack can now rest. 
     Then, the new, wider frame is slipped over from above and fastened on the pedestal. The rack supporting the internals is then fastened on the new frame. 
     Now, the fitting of the bottom plate can be performed and, if another bottom plate was provided on the old rack which did not need to be removed in order to remove the old housing, the new plate is fitted below the level of the old bottom plate, as a result of which the new bottom plate also only needs to surround the cables running from the bottom upwards and not further vertical struts originating from the old cabinet. 
     Owing to the design and the fitting sequence of the bottom plate, as described above, this is also easily and quickly possible in the case of the widened cabinet as a result of the accessible pedestal region which is free apart from the cables.

     DETAILED DESCRIPTION 
       FIG. 1  shows a switchgear cabinet  1  with a special physical shape of a cable distribution cabinet KVS, as is used in the public sector for accommodating domestic service connections for telecommunication lines and the like in large numbers. 
     In the cable distribution cabinet KVS, the outer protective cladding is removed on one of the end sides and the further cabinet module attached there is removed, while all of the rest is covered and protected in a conventional manner using flat elements made from plastic, i.e. roof elements, doors, pedestal cladding etc., which are fastened on an inner frame  7  comprising profiles along the longitudinal edges. 
     It can be seen on the open end side that this frame  7  has, at the height of the separation between the upper distribution compartment  4  and the lower pedestal region  3  of the interior of the cabinet, a transverse strut  7   a . The frame  7  has such a horizontal strut in the longitudinal direction  10  as well, namely the greater extent of the cable distribution cabinet KVS when viewed in plan view. 
     While the distribution compartment  4  is accessible by opening the doors of the cabinet, the pedestal region  3  is accessible by removing the pedestal cover  22 . 
     On the separating plane between the distribution compartment  4  and the pedestal region  3 , a bottom plate  2  fitted there acts as a separation, which is fastened on the horizontal struts  7   a , fitted at this height, of the frame  7  and is illustrated in  FIGS. 2 and 3 . 
       FIG. 1   b  shows the frame  7  of the cable distribution cabinet KVS at the beginning of the fitting of this bottom plate  2  when viewed in the longitudinal direction  10 . 
     As can be seen, the problem consists in the fact that the in general plurality of cables  15 , which are led up from the ground, pass from below first through the pedestal region  3  and then also through the separating plane to the distribution compartment  4 , along with the bottom plate  2 . This should produce precisely the seal with respect to the ingress of moisture from below between the pedestal region  3  and the distribution compartment  4  and, for this purpose, seal off the whole of the rest of the horizontal free space on this separating plane around the cables up to the outer frame  7 . 
     For this purpose, the cables  15  should not be removed and it is necessary to take into consideration the fact that the cables  15  are relatively stiff but are not entirely fixed in terms of their position, i.e. are still flexible to a limited extent between the point at which they are clamped at their upper free end in the distribution compartment  4  and the point at which they exit the ground at the lower end of the pedestal region, which makes sealing around these cables  15 , particularly over long periods of time, much more difficult since, even merely due to weather-dependent and therefore temperature-dependent material expansions, these cables move their position for example alternately between the summer and winter season or between day and night completely by measurable distances. 
     Such a bottom plate  2  in the ready-fitted state is illustrated in  FIG. 2 , but the design can be explained better with reference to the fitting state in  FIG. 3 . 
     The bottom plate  2  is split approximately in the center in the longitudinal direction  10 , the greater direction of extent in the plan view of the cable distribution cabinet KVS. The rectangular opening  9  in the bottom plate  2 , which opening takes up the entire central region and through which the cables  15  are intended to pass, is surrounded on all sides by the bottom plate  2  if the two plate parts  2   a, b  thereof are positioned opposite one another on the separating line  10 ′, as illustrated in  FIG. 2 . 
     In the fitted state, the opening  9  is completely filled with cable sealing blocks  5 , in which cable passages  12  can be opened through which, if required, in each case one cable  15  is guided, with the result that the inner circumference of the cable passage  12  of a sealing block  5  bears tightly against the outer circumference of the cable  15  (not illustrated). 
     The bottom plate  2  is generally a sheet-metal part. In order that the fitter, who works from the front side, as is shown in  FIG. 1   a , once the doors on the cabinet have been opened, can dismantle and then refit the bottom plate  2 , for example, because the complete housing  6  needs to be replaced owing to damage, for example, primarily only the pedestal region  3  is available for this purpose for said fitter to work with the bottom plate  2 , which pedestal region  3  is substantially empty apart from the cables  15  passed through. 
     The distribution compartment  4  located above this, on the other hand, is in practice partially filled with a fitting rack, in contrast to the illustration in  FIG. 1   b , with a large number of electrical devices being built on said fitting rack, which devices largely fill this space. 
     For this reason, the rear plate part  2   a  of the bottom plate  2 , which rear plate part  2   a  faces away from the fitter, is designed so as to be capable of being folded by means of a hinge  16 , which runs along the rear longitudinal edge, and can be folded downwards into the pedestal region  3  from the horizontal fitting position. In addition, the plate part  2   a  can also be removed entirely from the frame  7 , either by virtue of the hinge  16  being a separable hinge or by virtue of the hinge  16  being located within the plate part  2   a  and the plate part  2   a  being screwed on the frame  7 , in particular that part of the hinge  16  which is associated with the frame  7 . 
     The front plate part  2   b  facing the fitter is preferably not fastened in foldable fashion on the frame  7 , but can instead be raised into the fitting position from below, i.e. from the pedestal region  3 , as illustrated in  FIG. 1   b , and connected there to the horizontal struts  7   a  of the frame  7 . 
     The fixing on the frame  7  takes place in the case of both plate parts  2   a, b  by means of the toggle closures  24  illustrated in  FIGS. 2 and 3 , in the case of which toggle closures a radially protruding tab engages in a corresponding groove in the inside of the profiles, which form the frame  7 , in a form-fitting manner as a result of the rotation of the pin. 
     The plate parts  2   a, b  are sealed off with respect to one another and also with respect to the frame preferably by means of an interposed seal. 
     For fitting purposes, first the rear plate part  2   a  is folded up into its horizontal position and fixed there and then the front plate part  2   b  is raised out of the pedestal region  3  into the fitting position and likewise fixed on the frame  7 , i.e. the horizontal struts  7   a  thereof. However, before this the sealing blocks  5  need to be at least partially fitted. 
     In order that the sealing blocks  5  do not slide along the cable running direction, they are fixed in their position in a form-fitting manner with respect to the plate parts  2   a ,  2   b  by virtue of them being pushed onto guide bars  14 , which protrude forwards from the longitudinal edge  9   a  of the opening  9  in the rear, foldable plate part  2   a  in the plate plane, i.e. running in the transverse direction  11  into the opening  9 , and not only beyond the separating line  10 ′ between the plate parts  2   a ,  2   b , but also beyond the opposite longitudinal edge  9   a  of the front plate part  2   b.    
     In the illustration in  FIG. 3 , the guide bars  14 , which are arranged at uniform intervals along the longitudinal edge  9   a , are always illustrated on the lateral contact line between two sealing blocks  5 , but they will preferably run within the sealing blocks  5 , for example in each case slightly set back from the outer lateral edge of a sealing block into the interior since the guide bars should not cross the cable passages  12 , which are provided in the sealing blocks  5 . 
     The sealing blocks which are made from a foamed plastic, in particular a closed-cell foamed plastic, are furthermore split in the longitudinal direction  10  into in each case two block parts  5   a, b ; otherwise they can have a different configuration in terms of the way in which they are split. 
     First, the separating line  5 ′ between the block parts  5   a, b  can run in linear or nonlinear fashion, but preferably one of the block parts, for example  5   a ′, has projections which engage in corresponding cutouts of the other block part, with the result that these hollows interrupt a straight separating line  5 ′. 
     Preferably, however, a zig-zagged separating line  5 ′, as illustrated on the block parts  5   a, b , is selected which causes mutual centering of the block parts when they are pressed together in the transverse direction  11 . 
     In addition, the cable passages  12  can be arranged directly on the separating line  5 ′, as illustrated in the blocks  5 ′ and  5 ″, or to one side of the separating line in each case wholly in one of the block parts  5   a, b , or both in one sealing block, as illustrated using the block  5 ′″ a, b.    
     At least the block part  5   a ,  5 ′ a ,  5 ″ a  . . . of the split blocks is pushed onto the guide bars  14  before the plate part  2   a  is folded up into the horizontal position. During the folding-up process, the required already open cable passages  12  in the plugged-on block parts  5   a ,  5 ′ a , . . . are then laid around the cable circumferences. 
     Then, the block parts  5   b ,  5 ′ b ,  5 ″ b  which are further removed from the rear foldable plate part  2   a  are plugged onto the guide bars and pushed against the first block parts  5   a ,  5 ′ a ,  5 ″ a  . . . and positioned thereon and in the process likewise laid around the corresponding cables with their required, already open cable passages  12 . 
     Then, the front plate part  2   b  is inserted from the bottom and fixed on the frame  7  at the height of the struts  7   a . In order for this to be possible, in this case the size of the opening  9  in the transverse direction  11  is slightly larger than the width of the sealing blocks  5 . As a result, however, no reliable sealing between the sealing blocks  5  and the bottom plate  2  is as yet provided. 
     In order to achieve this, a press strip  19 , which runs in the longitudinal direction  10  over the entire length of the opening  9  and has an angled shape with a vertical and a horizontal limb in cross section, possibly also has a second horizontal limb, is then pressed against the front edges of the sealing blocks  5 . 
     This is achieved by virtue of the fact that the vertical limb of the sealing strip  19  has through-openings for the free ends of the guide bars  14  and a thread (not illustrated) is provided on these free ends. 
     Once the free ends have been pushed through the press strip  19 , threaded closures  20 , in particular quick-release closures, are screwed onto the thread of the guide bars  14  and, as a result, the press strip  19  is pressed against the sealing blocks  5 . 
     The press strip  19  is fastened displaceably in the transverse direction  11  with respect to the plate part  2   b  by virtue of the fact that pins protruding from the plate plane of the plate part  2   b  engage in longitudinal slots in the press strip  19  running in the transverse direction. 
       FIGS. 4 and 5  shows a sealing block  5  in detail. 
     First,  FIG. 5  shows the fact that the prefabricated cable passages  12  comprise ring-shaped cuts  23   a, b, c , which are not completely closed to form a ring, of different diameters, which ring cuts lie concentrically with respect to one another, with the result that the corresponding core part can be removed, depending on the diameter of the cable to be sealed, once the holding web  25  remaining opposite the sealing block has been severed manually. 
     In order to be able to introduce the cable, an access cut  8  reaches from the outer edge of the sealing block  5  beyond the outer ring-shaped cuts  23   b, c  as far as the innermost ring-shaped cut  23   a.    
     The holding webs  25  in the individual ring-shaped cuts are preferably provided on that side in the ring-shaped cut  23   a, b, c  which is opposite the access cut  8 . 
     The good sealing effect results inter alia from the fact that the sealing blocks  5  have a height of several centimeters and therefore a long sealing length with respect to the cable outer diameter. 
     In order to further improve this, the ring-shaped cuts  23  and the access cut  8  extend not only over the entire height, i.e. the thickness, of the sealing block  5 , as is illustrated primarily in  FIGS. 4   b  and  4   e , but the circular ring-shaped cuts  23  do not form a cylindrical shape, but a conical shape, by virtue of the fact that they are inclined with respect to the vertical mid-axis of the cable passage  12  through a cone angle of a few degrees. 
     In order that the block parts  5   a  and  b  do not slide with respect to one another in the longitudinal direction  10  when they are pressed together, their separating line  5 ′ preferably has a zig-zag configuration, the access cut  8  and also the center of the cable passages  12  preferably being at the height of in each case one tip, in particular the outwardly pointing tip, of a block part  5   a, b.    
     This also makes it possible to achieve a situation in which the two block parts  5   a, b  have an identical configuration, with the result that only one type of block parts needs to be kept in stock.
