Description

Technical Field

[0001] The invention is based on a switch cabinet with at least one brush strip for conductor feedthroughs, wherein the switch cabinet has a switch cabinet frame with a horizontal or vertical profile frame from which profile webs extend. Such a switch cabinet is known from DE 10 2015 121 192 A1. Background Art

[0002] In order to introduce conductors, such as cables or other supply lines, into the interior of a switch cabinet, it is known to use brush strips fixed to the frame frame of the switch cabinet via the frame frame's system perforations by means of cage nuts etc. The assembly of the brush strips is therefore usually tool-constrained and correspondingly time-consuming. Summary of the invention

[0003] It is therefore the object of the present invention to further develop a switch cabinet of the type mentioned above in such a way that a simple and, in particular, tool-free mounting of the brush strip on the frame of the switch cabinet is possible.

[0004] This object is achieved by the switch cabinet according to the invention.

[0005] It is thus provided that a brush strip is placed on the free end of the profile web, the brush strip having bristles extending from the profile web on the inner circumference of the profile frame. The invention thus makes use of the profile web present on the profile frame of the frame, which, for example in the frame known from DE 10 2015 121 192 A1, can be a sealing web, by means of which the flat part fixed to the frame can be sealed relative to the frame, if necessary, by means of an additional sealing element.

[0006] At least one wall or top plate can be mounted on a horizontal or vertical profile frame, which wall or top plate partially encloses the profile frame and has a free edge extending parallel to the brush strip and abutting against the free bristle engagement edge of the brush strip. In this case, the wall or top plate can have a further brush strip complementary to the brush strip, in particular opposite to the brush strip, the free bristle end of which forms the free edge of the wall or top plate.

[0007] The brush strip can have an adapter with a plug-in receptacle, via which the brush strip is plugged onto the profile web, wherein the bristles of the brush strip extending parallel to one another are formed in one piece with the adapter.

[0008] The adapter can have a contact surface for the flat part of the switch cabinet on its outer side facing away from the profile web. The profile web can be a circumferential sealing web of the profile frame and the contact surface of the adapter can be a sealing surface against which the flat part bears with contact pressure. In this case, the adapter can be made at least partially and preferably completely of sealing material, the bristles of the brush strip being held by the adapter via their ends facing away from the free ends of the bristles.

[0009] The profile web can widen towards its free end, via which the brush strip is placed on the profile web via its adapter. In this case, the receptacle can be undercut. The plug-in receptacle can be made of an elastic material, so that the profile web is received in the plug-in receptacle in a substantially form-fitting manner.

[0010] The profile web can have a vertical or horizontal profile side on the inner periphery of the profile frame and another profile side at an acute angle to the outer periphery of the profile frame. The plug-in receptacle can have a stop against the vertical or horizontal profile side.

[0011] The plug-in receptacle can be defined opposite a stop by a clamping section which can be displaced relative to the stop against a mechanical pretension between a release position and a clamping position in which the adapter is released from the profile web and in which the clamping section rests and is pressed against the profile web by the pretension.

[0012] At least the plug-in receptacle of the adapter can be formed as a single piece and completely formed from the same plastic material, for example from an elastomer or a soft plastic. In this case, the stop can have a material thickness that is at least 30% greater than the clamping section. Preferably, the stop has a material thickness that is at least 50% greater than the clamping section.

[0013] The clamping section can have a curved section at its free end, at which it merges into an end section, along which it bears against a drainage chamfer on the outer circumference of the profile frame, into which drainage chamfer the profile web merges.

[0014] The profile frame may be a top frame of the housing, wherein the free ends of the profile webs to which the brush strips are fitted form a horizontal circumferential sealing edge of the top frame. The top frame may have a drainage slope on the periphery of the sealing webs adjacent to the sealing webs, which drainage slope leads to a horizontal rain gutter of the top frame.

[0015] The brush strip, preferably the adapter of the brush strip, may have a deflector on its side facing the rain gutter, extending from the upper end of the brush strip, preferably from the upper end of the adapter toward the drainage slope. The deflector may be formed as a sealing lip, which is fixed at the upper end of the brush strip and preferably fixed at the upper end of the adapter and extends a certain distance from the adapter toward the drainage slope.

[0016] The brush strip may have a sealing edge at its end face, with which a plate edge of a wall or ceiling plate may be brought into sealing contact.

[0017] The switch cabinet can have a wall or a roof with an opening which is aligned with the bristles of the brush strip or the bristles of the brush strip are arranged in the opening, the brush strip being arranged between the wall or the roof and the profile frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Further details of the present invention are explained below with reference to the accompanying drawings. It is shown thereby:

[0019] Figure 1 A perspective view showing a vertical section of a first embodiment of a switch cabinet according to the invention; and

[0020] Figure 2 Show according to Figure 1 An embodiment in which the brush bar is removed and the flat portion is indicated. DETAILED DESCRIPTION

[0021] Figure 1 An exemplary embodiment of a switch cabinet 1 is shown, in which the switch cabinet frame 2 and in particular the cross section of the profile struts of the switch cabinet frame 2 has a geometry known from DE 10 2015 121 192 A1. The switch cabinet frame 2 is characterized in that profile webs 5 extend from horizontal and vertical profile frames 4 of the switch cabinet frame 2 and are undercut, i.e. widen towards their free ends.

[0022] The profile web 5 is a sealing web which extends from the outer side of the corresponding profile frame 4 facing away from the switch cabinet 1 and can, for example, form a circumferentially closed profile web frame. The circumferentially closed profile web frame can be used to seal the flat section relative to the corresponding profile frame 4 (if necessary, by means of a sealing element which is, for example, applied to the inner side of the flat section and into which the profile web 5 is pressed via its free end) in order to seal the switch cabinet frame 2 relative to the flat section.

[0023] According to the invention, the profile web 5 is now assigned a second function, which serves to hold the brush strip 3 attached to the free end of the profile web 5. Bristles 6 extend from the brush strip 3 on the inner periphery of the profile frame 4. In this case, the profile frame 4 is the top frame of the switch cabinet frame 2, which is partially closed by the top plate 7. The complementary brush strip 10 is attached to the free longitudinal edge of the top plate 7, so that the brush strips 3, complementary brush strips 10 abut against each other with the free ends of their bristles and thus provide effective protection against the ingress of dust and other light objects into the interior of the switch cabinet. Although the brush strips 3, complementary brush strips 10 are arranged "butted", as is generally known in the prior art, this may include the bristles of the opposing brush strips 3, complementary brush strips 10 at least partially interlocking or overlapping.

[0024] The brush strip 3 has an adapter 12 with a plug-in receptacle 13, via which the brush strip 3 is plugged onto the profile web 5 designed as an undercut sealing web. The adapter 12 can be made, for example, in one piece from an elastomer or soft plastic with the bristles 6 of the brush strip 3. In particular, the bristles 6 can be molded into the adapter 12. On the upper side, the adapter 12 has a contact surface 14 for the flat section 15 (see Figure 2 ). The contact surface 14 can in particular be a sealing surface, for which purpose the contact surface 14 and preferably the entire adapter 12 are made of a corresponding sealing material, such as an elastomer, so that the flat part 15 effectively seals relative to the profile frame 4 when the flat part rests on the contact surface 14 and a suitable contact pressure of the flat part on the contact surface 14 is provided. The contact pressure can be provided, for example, by means of a common flat part holder for mounting the flat part on the switch cabinet frame rack.

[0025] The adapter 12 has a plug-in receptacle 13, by means of which the adapter 12 is plugged onto the profile web 5. The plug-in receptacle 13 is formed as an undercut extending in the longitudinal direction of the adapter and therefore in the longitudinal direction of the brush strip 3. In order to achieve a defined positioning of the brush strip 3 relative to the profile frame 4 when the brush strip is plugged onto the profile frame 4, in particular onto the profile web 5, it is provided that the plug-in receptacle has a stop 18 that abuts against a vertical profile side 16 facing the inner periphery of the profile frame 4. Opposite the stop 18, the plug-in receptacle 13 has a clamping section 19, which together with the stop 18 defines the plug-in receptacle 13.

[0026] The clamping section 19 can be displaced relative to the stop 18 against a mechanical pretension between a release position, in which the adapter 12 is released from the profile web 5, and a clamping position, in which the clamping section 19 rests against the profile web 5 and is pressed against by the pretension. In this case, the fixation and defined prepositioning of the brush strip 3 relative to the profile web 5 is achieved by the fact that the plug-in receptacle 13 of the adapter 12 is formed in one piece and entirely from the same plastic material, and the stop 18 has a greater material thickness than the clamping section 19. Preferably, the thickness of the stop 18 is at least 30% greater than the thickness of the clamping section 19. This ensures that when the brush strip 3 is pressed onto the profile web 5, the mechanical pretension of the plug-in receptacle 13 is absorbed by the clamping section 19, wherein the clamping section 19 undergoes an elastic deformation, while the stop 18 remains substantially undeformed. The pretensioning force acting perpendicularly to the stop 18 in turn causes the stop 18 to press against the vertical profile side 16 on the inner circumference of the profile frame 4 , whereby the brush strip 3 assumes a defined position relative to the profile frame 4 .

[0027] The adapter 12 has a deflector 24 on its side extending along the periphery of the profile frame 4, which extends from the upper end of the brush strip 3 (in the present case adjacent to the clamping section 19 and formed integrally therewith) towards a drainage bevel 22 of the profile frame 4. The profile frame 4 designed as a horizontal top frame has a drainage bevel 22 on its periphery adjacent to the profile web 5, which drainage bevel 22 opens into a horizontal rainwater gutter 23 of the top frame.

[0028] Figure 1 and Figure 2 The summary shows that the arrangement of the brush strip 3 according to the invention on the profile frame 4 makes it possible to effectively seal the flat part 15, for example the roof of the housing in this case, relative to the switch cabinet frame 2. Figure 1 As described, the brush strip 3 can be made of an elastic sealing material in the region of its adapter 12 , so that sealing of the flat section 15 relative to the profile frame 4 is achieved when the flat section 15 is pressed against the profile frame 4 via the contact surface 14 of the adapter 12 .

[0029] The features of the invention disclosed in the above implementing description, the drawings and the claims may be essential for the realization of the invention both individually and in any combination.
