Definitions

  • the invention relates to a device for covering fuse holders that can be placed on busbars with threaded sleeves that hold the fuses.
  • a rectangular, box-like cover plate with a number of fuses corresponding to the number of fuses, which are provided on the underside of the cover plate with projecting guide webs for receiving the threaded sleeves, can be plugged onto the fuse holder in that the Narrow sides of the cover plate on the underside are designed as plug-in receptacles for inserting plug-in extensions of side plate plates and that the side plates are provided with break lines for breaking out insertion openings.
  • the cover plate holds itself on the threaded sleeves of the fuse holder via the guide webs, without impairing the screwing in and unscrewing of the fuses held in screw caps.
  • the side plates which are plugged together with the cover plate complete the cover on the narrow sides from the top of the fuse holder to the busbars or the wall carrying the busbars. In the side plates, correspondingly large insertion openings have been broken out for the connecting lines leading to the fuse holder.
  • one embodiment provides that the guide webs are adapted to the outer circumference of the threaded sleeves and are divided over the circumference thereof.
  • a configuration is useful, which is characterized in that the top of the cover plate is provided with recesses for license plates, since the identification is possible with the fuse holder fully covered.
  • the side plates are box-shaped and with their open sides facing each other can be connected to the cover plate, the underside of which faces the fuse holder.
  • a good hold of the plug connections between the side plates and the cover plate is obtained according to a further embodiment in that the plug receptacles of the cover plate for cross-sectionally U-shaped approaches of the side plates are limited and formed by their side wall and by molded-on retaining webs on the underside of the cover plate.
  • the stability of the cover plate can be improved in that the cover plate is stiffened in the region of a narrow side by means of a transverse wall and in that the upper side of the cover plate has a transverse groove above the transverse wall
  • the break lines on one side plate on the side opposite the plug-in attachment specify different-sized portal-like insertion openings, while the break lines on the other side plate on the side facing away from the plug-in attachment divide approximately rectangular, different-sized insertion openings, which almost separate extend to the insertion of this side plate.
  • the break lines are preferably predetermined by areas of the side plates that are reduced in wall thickness.
  • a further embodiment provides that protruding, receptacle-forming pairs of guide tongues are formed on the long sides of the cover plate in the plane of the side wall, into the T-shaped retaining lugs of Rectangular, box-like blind cover plates can be inserted without openings that the retaining lugs on the side wall of the blind cover plate correspond laterally and on the short side are attached staggered and that the narrow sides of the blind cover plate are provided on the underside with the same plug receptacles for ice plugging of side plates as the cover plate.
  • the blind cover plate has the same dimensions as the cover plate and the same side plates in its plug receptacles as the plug receptacles of the cover plate in order to remain in the division of the fuse holder and the cover plate.
  • the insertion of the retaining lugs of the blind cover plate into the receptacles formed on the cover plate by the pairs of guide tongues is facilitated in one embodiment in that the mutually facing free corners of the pairs of guide tongues are chamfered to form an expanding insertion opening for the associated retaining lug and that Distribution of the pairs of guide tongues on the cover plate is matched to the distribution of the retaining lugs on the blind cover plate.
  • the cover plate, the side plates and the blind cover plate are designed as one-piece plastic injection molded parts, with the associated parts and elements being molded in one operation.
  • the cover plate 10 shown in FIGS. 1 and 2 has three openings 11 for fuses.
  • the cover plate 10 is rectangular and box-shaped, as can be seen from the peripheral side wall 14.
  • receptacles 13 for license plates are introduced in order to be able to identify the protected circuits even when the fuse holder is covered.
  • guide webs 12 are formed in the area of the openings 11, which protrude above the underside and, as shown in FIG.
  • the guide webs 12 are therefore divided and adapted to the outer contour of the threaded sleeve 27.
  • the clamping jaws 28 form receptacles 29 for the busbars, so that the fuse holder 26 only has to be hooked onto the busbars and needs to be fixed to it by tightening the clamping jaws 28.
  • the side plates 20 and 23 are attached to the cover plate 10. These side plates 20 and 23 end in plug-in lugs 21 and 24, which, like the side plates, are box-shaped. However, the side walls are missing on the narrow sides, so that the cross section of the plug-in projections 21 and 24 is U-shaped.
  • the circumferential side wall 14 with holding webs 35 to 37 or 38 to 40 formed on the undersides forms a plug-in receptacle 15 or 16, which receives the plug-in extension 21 or 24 of the side plate 20 or 23 in a clamping manner. As shown in FIG.
  • the fuse holder 26 is also covered on both narrow sides by the cover thus assembled, at least up to the area of the busbars or even up to the wall carrying the busbars.
  • the openings 11 of the cover plate 10 still remain free, so that the fuses can be screwed into and out of the threaded sleeves 27 with a screw cap.
  • the side plate 20 has on the side opposite the plug-in extension 21 the portal-like fracture lines 22, which are formed by weakening the wall thickness, in order to be able to break out insertion openings for the connecting cables.
  • the break lines 25 are approximately rectangular and extend almost up to the plug-in projection 24.
  • the break lines 22 and 25 are arranged in such a way that an insertion opening of different sizes can be broken out.
  • the cover plate 10 carries a stiffening transverse wall 41 in the region of the underside of a narrow side and a groove 17 above it in the upper side.
  • the transverse groove 17 lies above the transverse wall 41 formed on the underside and prevents sink marks when the cover plate 10 is produced as a plastic injection-molded part.
  • 10 pairs of guide tongues 18 and 19 are formed along the longitudinal sides of the cover plate, which lie in the plane of the side wall 14, but protrude from it.
  • a pair of these guide tongues 18 and 19 forms a receptacle for a holding projection 31 which is integrally formed on the side wall 35 of the blind cover plate 30 according to FIGS. 6 and 7.
  • This blind cover plate 30 has the same dimensions as the cover plate 10 and is also box-shaped. It carries on the underside of the narrow sides of the same designed receptacles 33 and 34, in which the same side plates 20 and 23 can be inserted. In this way, an intermediate space between two fuse holders 26 can be covered, which, like the fuse holder, occupies a division of the busbars.
  • the retaining lugs 31 of the blind cover plate 30 are inserted into the receptacles formed by the pairs of guide tongues 18 and 19. Since the free corners of the guide tongues 18 and 19 facing each other are chamfered, the insertion of the retaining lugs 31 is facilitated.
  • the retaining lugs 31 on the long sides of the blind cover plate 30 are attached in the same distribution as the pairs of guide tongues 18 and 19 on the long sides of the cover plate 10. However, the holding lugs 31 are offset relative to the side wall 35 of the blind cover plate 30, so that after the Connection the upper sides of the cover plate 10 and the blind cover plate 30 are flush and the side wall 14 of the cover plate 10 bears against the side wall 35 of the blind cover plate 30.
  • cover plates 10 can be lined up without this plug connection, since they are held on the fuse holders 26.
  • the connecting elements on the two long sides of the cover plate 10 and the blind cover plate 30 are each complementary to one another.
  • cover plates 10 can also be connected to one another along their long sides.
  • the blind cover plate 30 can again have a transversely directed groove 32, which performs the same function as the groove 17 on the cover plate 10.
