Definitions

  • the invention relates to connecting rails made from a profiled semi-finished product for connecting the electrical components of electrical devices and apparatus to an external circuit, the connecting rails extending through window openings in the device or device wall and being fixed in the housing by means of fastening means.
  • a system-side supply rail can be connected to the part of a connecting rail which is led out of the housing.
  • the connecting rail is usually fixed in the insulating wall body of a device or apparatus, which is usually realized with the help of through openings and fasteners.
  • the connecting rails must continue to be designed so that they can be produced efficiently and are suitable to perform certain functions. These functions are: the current carrying capacity, the heat dissipation, an area for connections from
  • connecting rails for different currents in a uniform housing with uniform through openings.
  • screws which extend through openings arranged transversely to the longitudinal axis of the connecting rails and for the reception of which a nut thread is generally provided in the wall of the corresponding housing are used as fastening means for the connecting rail.
  • metallic insert nuts or press-in nuts are used for this in a housing consisting of an insulating material.
  • connecting rails which are sawn from a profile material with one or more projections, such that the connecting rails are inserted through a hole and the projection or projections of the profile material as stops serve the connection rail on the switch housing and thus form the power transmission of the switching forces to the housing.
  • this connecting rail special profiles are used, which have an integrally molded strip. Pieces are then cut from the profiles, which form the connecting rail.
  • connecting rails of different thicknesses within a series of circuit breakers depending on the nominal current.
  • These connecting rails are also made from profiles by sawing.
  • the housing has uniform cutouts for the connection rails, which are each designed for the largest nominal current.
  • Plastic spacers that fill the gaps are used for thinner connecting rails with smaller nominal current strengths.
  • the assembly of the spacers has the disadvantage of additional costs for these parts as well as higher assembly costs and they form a source of error when the current paths are installed by the customer.
  • the connecting rails are made of solid material, regardless of the other manufacturing technology. This means that the rails also have different cross sections for different currents and thus different external dimensions; a disadvantage that has already been dealt with above.
  • Hollow current-carrying conductors are known from high-voltage and high-frequency technology. With these waveguides the hollow training only for the purpose of corona losses
  • Conductor i.e. to reduce the radiation of energy at sharp edges or narrow radii, or to take into account the skin effect, which is based on the fact that at high frequencies, energy is only transmitted in the outer region of a conductor, but not for the purpose of a different current-carrying capacity to ensure a uniform outer cross-section.
  • a current-carrying hollow arrangement is also in the
  • An electronic circuit is installed in the connector of the device. Although a current-carrying hollow part of an electrical switching device has become known, this is only used to accommodate another component of the device, namely the electronic circuit mentioned and not to regulate the current carrying capacity of the component.
  • the object of the present invention is therefore to design connecting rails in such a way that they have the same outer cross section even at different nominal current values and can be used without additional spacers in equipment and apparatus housings with uniform through openings.
  • connecting rails for electrical devices and Apparatus are hollow, where they can have only one, as well as several cavities.
  • the connecting rails have the same outer cross-section for all different current strengths.
  • the current carrying capacity is thus regulated by means of the wall thickness of the hollow rail, which forms the conductive, current carrying cross section. It follows from this that there is a larger internal cavity at lower current strengths due to low wall thicknesses, or a smaller internal cavity at higher current strengths due to thicker wall thicknesses, which can lead to a massive design without a cavity and at the highest rated current strength.
  • the through openings in the respective device and apparatus housings are then designed for the external dimensions required for this highest rated current.
  • holes may be required which can be designed with or without a thread, for example for fastening purposes on the housing or against axial displacement. These holes can be arranged in a common axis or also offset from one another.
  • suitable webs can be provided between the cavities of the connecting rails to increase the strength. This may mean additional work with regard to the production of the profile material, but has no influence on the current carrying capacity.
  • Connection rails running guide grooves can be provided for support webs to be inserted if necessary.
  • the support webs to be inserted into these guide grooves can consist of the same material as the connecting rail, but can also consist of a different material.
  • These inserted support webs serve the same purpose as the molded one, namely the stabilization of the connecting rail against deformation of the hollow connecting rail by the clamping force or loading of screw bolts passed through the holes or screws screwed into the thread of these holes.
  • the aforementioned bores, with or without a thread, can be arranged in the region of cavities, which is particularly expedient if through bolts are passed through, in which case they must have a common axis and do not require a thread.
  • the bores are designed with a thread, it can be advantageous to arrange them so that they are located in a web. This makes longer thread lengths possible, which enables the screw connection to withstand greater loads.
  • the connecting rails can also be provided with stops known per se for axial fixation. You will then be sent through appropriate known fastening elements, for example clamping screws, are fixed in the axial direction. At the same time or in addition, such stops can absorb axial forces and transmit them to the housing.
  • the cavity or the cavities can be arranged transversely to the longitudinal extent of the connecting rail and can be open on both sides.
  • an extruded profile can advantageously be produced as the starting material, from which individual connecting rails of a required width can be separated.
  • Figure 1 shows schematically a first embodiment of a connecting bar, for a low current.
  • Figure 2 shows schematically a second embodiment of a connecting bar, for a higher current.
  • FIG. 3 schematically shows a third embodiment of a connecting bar, with a cavity and fastening bores.
  • FIG. 4 schematically shows a fourth embodiment of a connecting bar with several cavities.
  • FIG. 5 shows schematically a fifth embodiment of a connecting bar with several cavities.
  • FIG. 6 schematically shows a sixth embodiment of a connecting rail, with a cavity and insertable support webs arranged therein.
  • FIG. 7 schematically shows a seventh embodiment of a connecting rail, with stops for axial fixation.
  • FIG. 8 shows a top view of a connecting bar with an indicated apparatus wall.
  • FIG. 1 shows a first embodiment of a connecting bar 1 for electrical devices and apparatus for a low current.
  • this connecting bar 1 has only a single cavity 2, which extends essentially over its entire dimension.
  • This connecting bar 1 has a thinner wall 3 adapted to the low operating current. Since the external dimensions, that is to say the external cross section of the connecting bar 1, should represent a constant size, the cavity 2 is relatively large because of the small wall thickness.
  • FIG. 2 shows a second embodiment of a connecting bar 4 for electrical devices and apparatus for a higher current. In this embodiment, it also has only a single cavity 5, which extends essentially over its entire dimension.
  • This connecting bar 4 has a thicker wall 6 which is adapted to the higher operating current. Since the outer dimensions, that is to say the outer cross section of the connecting bar 4, should also represent a constant size, the cavity 5 is relatively small because of the thicker wall thickness.
  • FIG. 3 shows a third embodiment of a connecting bar 7 for electrical devices and apparatus with a cavity 8 which extends essentially over its entire dimension.
  • This connecting rail 7 has holes 9; 10; 11; 12, which are provided for fastening purposes and optionally have a thread.
  • the bores 9 and 10 are arranged in a common axis, which is necessary when using through bolts, and the bores 11 and 12 are arranged offset, which can be expedient, for example, when using individual screws. Then these holes are threaded.
  • FIG. 4 shows a fourth embodiment of a connecting bar 13 for electrical devices and apparatus with several
  • this connecting rail 13 holes 14; 15; 16; 17 provided in the area of the cavities 18, 19 and 20.
  • the above-mentioned webs 21 and 22 serve to increase the strength and to avoid deformation of the hollow connecting rail 13 by the clamping force or loading of the screw bolts passed through these bores 14 to 17 or screws screwed into the thread of these bores 14 to 17.
  • FIG. 5 shows a fifth embodiment of a connecting bar 23 for electrical devices and apparatus, with a plurality of cavities 24; 25; 26.
  • the bores 27; 28 arranged so that they are in a web 29; 30 are located. This allows longer thread lengths, which enables the screw connections to be more resilient.
  • FIG. 6 shows a sixth embodiment of a
  • Connection rail 31 for electrical devices and apparatus with a substantially the entire extent of the
  • connection rail 31 extending cavity 32.
  • the profiled semifinished product has guide grooves 35; 36; 37; 38, in which support webs 33; 34 can be inserted.
  • the in these guide grooves 35; 36; 37; 38 support webs 33; 34 can consist of the same material as the connecting bar 31, but can also consist of a different material.
  • This inserted support webs 33; 34 serve the same purpose as the molded one, namely the stabilization of the connecting bar 31 against deformation of the hollow connecting bar 31 by the clamping force or loading of the holes 39; 40; 41; 42 threaded bolts or screws screwed into the thread of these holes. However, no holes can be arranged in them.
  • FIG. 7 shows a seventh embodiment of a connecting bar 43 for electrical devices and apparatuses with stops 44; 45 for axially fixing the connecting rail
  • FIG. 8 schematically illustrates one of the connection rails described above, e.g. B. the connecting bar 1 ( Figure 1) in plan view. As can be seen, the cavity 2 extends transversely to the longitudinal direction and is open on both sides. Furthermore, a wall of an apparatus housing 46 is indicated, through which the connecting bar 1 extends.
  • the advantages of the inventive solution are that uniform outer dimensions of the connecting rails are achieved within one size, whereby spacers and the like are eliminated. Uniform insertion openings and thus uniform housing dimensions can be used within one size, which results in a large reduction in the number of variants and a reduction in costs.
  • the holes in the hollow profiles can be punched, which is cheaper and cleaner than drilling.
  • the connection technology is simplified to one variant per size, which simplifies production. Due to the greatly enlarged surface of hollow profiles that are open on the side, there is better heat dissipation.

Abstract

L'invention concerne des profilés de raccordement (1; 4; 7; 13; 31; 43) d'appareils et de dispositifs électriques destinés à différents courants nominaux. Ces profilés sont de conception creuse et peuvent présenter une seule ou plusieurs cavité(s) (2; 5; 8; 18-20; 24-26; 32). Les profilés de raccordement (1; 4; 7; 13; 31; 43) ont la même section externe pour toutes les intensités de courant mais ils ont des parois d'épaisseurs différentes pour les différentes intensités et donc des cavités de différentes tailles (2; 5; 8; 18-20; 24-26; 32). Ainsi, les passages des profilés de raccordement des boîtes de commutation concernées d'une série type peuvent tous être identiques, correspondant aux dimensions des profilés de raccordement de l'intensité maximale.
