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 (2a) can be folded down and the other half (2b) 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).
Claims42
A cable distribution cabinet comprising:
- a housing including a frame, the housing including a pedestal region arranged beneath a distribution compartment,
- a bottom plate separating the pedestal region from the distribution compartment, the bottom plate including at least one plate part and the bottom plate defining a central opening through which cables pass to enter the distribution compartment,
- wherein the at least one plate part of the bottom plate is configured to be folded about a longitudinal axis of the plate part relative to the frame.
A cable distribution cabinet with a housing, in which a pedestal region is arranged beneath a distribution compartment, the cable distribution cabinet comprising:
- a bottom plate that separates the pedestal region from the distribution compartment, the bottom plate defining an opening configured to enable a plurality of cables to pass through in a vertical cable running direction,
- a plurality of sealing elements located in the housing, the sealing elements including sealing blocks made from elastic, foamed material in which cable passages are formed, the sealing elements having a sealing length in the vertical cable running direction of more than 30 mm.
A bottom plate for a switchgear cabinet, the bottom plate being located between a pedestal region and a distribution compartment of the switchgear cabinet, the bottom plate comprising:
- a plurality of cable sealing elements in a central region of the bottom plate, and
- a plurality of plate parts with a separating line therebetween, which runs parallel to a longitudinal direction of the switchgear cabinet,
- wherein the cable sealing elements are sealing blocks made from elastic, foamed material, with a sealing length in a vertical cable running direction of more than 30 mm, wherein cable passages are formed in the cable sealing elements.
The bottom plate as claimed in claim 29, wherein the sealing blocks, which are dimensioned to have the same length in the longitudinal direction and to have an identical design, are arranged in the central region of the bottom plate in the longitudinal direction.
A method for fitting a two-part bottom plate in an opening of a cable distribution cabinet, the opening having a length and being located between a pedestal region and a distribution compartment of the distribution cabinet, at least the distribution compartment including a frame, the method comprising:
- fastening a first, foldable plate part on a horizontal transverse strut of the frame,
- folding down the first plate part, the first plate part including guide bars;
- pushing first sealing block parts onto the guide bars of the folded-down plate part over the entire length of the opening,
- folding up the first plate part and, in the process, inserting cables into corresponding cable passages in the first sealing block parts which have already been pushed onto the guide bars,
- fixing the folded-up plate part in a horizontal position in comparison with the frame,
- pushing, in a transverse direction, second sealing block parts onto the guide bars over the entire length of the opening and, in the process, inserting additional cables into cable passages of the second sealing block parts,
- feeding a second plate part through the distribution compartment from below into a plate plane and fixing the second plate part there in relation to the frame,
- pushing a press strip with through-openings onto the guide bars, and
- applying a threaded closure to a thread at a free end of each guide bar and prestressing the sealing blocks in the transverse direction with the aid of the threaded closures and the press strip.
