Abstract

A switch cabinet with at least one brush strip for the conductor feed-through, the switch cabinet having a switch cabinet frame with a horizontal or vertical profile frame from which a profile web extends, wherein the brush strip is placed on a free end of the profile web with bristles extending from the profile web over the inner portion of the profile frame.

First claim

The invention claimed is:

1. A switch cabinet comprising:
a plurality of horizontal and vertical profile frames defining an exterior boundary of the switch cabinet, at least one horizontal or vertical frame of the horizontal or vertical profile frames having an exteriorly extending profile web;
a first brush strip for feed-through of conductors;
the first brush strip including an adapter, the adapter having a plug in receptacle, the plug in receptacle being plugged on to a free end of the exteriorly extending profile web;
the adapter holding the first brush strip over an inner portion of the switch cabinet, the adapter presenting a flat sealing surface; and
a flat roof panel secured to the flat sealing surface of the adapter.

2. The switch cabinet according to claim 1 , further comprising a plate mounted on at least another horizontal or vertical frame of the horizontal or vertical profile frames, opposite the first brush strip, which the plate has a second brush strip that partially closes the inner portion of the switch cabinet, the second brush strip having a free edge which extends parallel to the first brush strip and butts against a free bristle butt edge of bristles of the first brush strip.

3. The switch cabinet according to claim 1 wherein bristles of the first brush strip, which extend parallel to one another, are formed integrally with the adapter.

4. The switch cabinet according to claim 3 , in which the adapter is formed at least partially from a sealing material, by which ends of the bristles of the first brush strip are held.

5. The switch cabinet according to claim 3 , in which the exteriorly extending profile web has a first vertical profile side facing an interior of the switch cabinet, and a second vertical profile side facing an exterior of the switch cabinet, the adapter having a stop which bears against the first or second vertical profile side.

6. The switch cabinet according to claim 5 , wherein the adapter further comprises:
a clamping section that is pretensioned against a side of the exteriorly extending profile web opposite the stop.

7. The switch cabinet according to claim 6 , in which the adapter is formed in one piece from an elastomer or a soft plastic, wherein the stop has a material thickness which is at least 30% greater than the clamping section.

8. The switch cabinet according to claim 6 , in which the clamping section has a bend at a free end of the clamping section, and wherein the exteriorly extending profile web has a run off sloping section extending exteriorly of the switch cabinet, and wherein the bend of the clamping section rests against the run off sloping section of the exteriorly extending profile web.

9. The switch cabinet according to claim 1 , in which the at least one horizontal or vertical frame is a roof frame of the switch cabinet, the roof frame having a drainage slope and a horizontal gutter, the drainage slope opening into the horizontal gutter, and wherein on a side of the adapter that faces the horizontal gutter, a deflector of the adapter extends towards the drainage slope.

10. A switch cabinet comprising:
a profile frame defining an upper exterior boundary of the switch cabinet, the profile frame having an upwardly extending web section, a lower part of the upwardly extending web section blending into a downwardly sloping section which terminates in a horizontal gutter;
a horizontally extending brush strip having an adapter and a plurality of horizontally extending bristles connected to an interiorly facing, downwardly extending side of the adapter, the adapter including:
an upper horizontal sealing surface,
an undercut section that mates with the upwardly extending web section of the profile frame to plug onto the adapter the profile frame,
a downwardly extending stop section engaging an interior side of the upwardly extending web section of the profile frame, and
a downwardly extending clamping section pressing against an exteriorly facing side of the upwardly extending web section;
and
a flat roof plate having an end portion secured to the upper horizontal sealing surface of the adapter.
