Definitions

  • the present invention relates to a busbar arrangement, in particular for low-voltage halogen lighting systems.
  • Busbars have the advantage that the consumers (lamps) can be variably connected to them at practically any point.
  • the busbars In addition to the power supply, the busbars generally also serve to mechanically hold the lamps connected to them.
  • the conductor rails usually consist of dimensionally stable tubes or hollow profiles with longitudinal slots for receiving two or even three mostly bare conductors. The conductors are against each other and also when using a conductive material for the tube or hollow profile enveloping them arranged isolated from this. Specially adapted connection parts are generally provided for feeding the voltage into the busbars, connecting the lamps and connecting several busbars or busbar sections with one another. These must ensure reliable contact and, like the busbars themselves, have sufficiently high mechanical stability and resilience.
  • the busbar arrangement according to the invention shown therein consists of a cable duct 1 with a perforated cable 2 inserted therein.
  • the cable duct 1 has a uniform, essentially U-shaped profile in its longitudinal direction and thus two leg strips 1.1, 1.2 and a base strip 1.3. It is preferably made of a plastic material and in the extrusion process.
  • the perforated cable is a flat, two-core cable. Its two wires 2.1 and 2.2 are enclosed by a rubber-elastic insulation 2.3 and preferably consist of a tinned copper wire with a cross section of 1 mm2. Holes 2.4 are punched into the insulation 2.3 at regular intervals of preferably, for example, 2.5 cm between the two wires. The holes 2.4 are dimensioned longer in the longitudinal direction of the perforated cable 2 than perpendicular to it and thereby roughly oval shaped. You uncover a short piece of both wires. Two such exposed sections are designated 2.5 in FIG. 2.
  • the cable duct 1 is provided with an inner contour on the inside of its two leg strips 1.1 and 1.2.
  • the inner contour is adapted to the outer contour of the perforated cable 2 in order to hold it between the two leg strips 1.1, 1.2, as can be seen in FIG. 1.
  • the perforated cable 2 in the cable duct 1 is aligned with its two flat sides parallel to its base strip 1.3.
  • the inner contour can, as shown, be formed by grooves 1.4 in the leg strips 1, 1, 1.2 and / or by webs thereon.
  • the two leg strips 1.1, 1.2 of the cable duct 1 naturally yield somewhat resiliently.
  • the inner contour of the cable duct and the suspension characteristics of its two leg strips are now designed and matched to one another so that the entire length of the perforated cable 2 can be pressed into the cable duct 1 by hand from the outside, with its leg strips 1, 1, 1.2 apart, and in Cable duct 1 engages under the spring back of the side rails.
  • a cover can also be used for optical reasons be provided for the cable duct. This can of course also be designed and attached to the cable duct so that it additionally secures the perforated cable in the cable duct against slipping out.
  • a connector of the type shown in FIG. 4 is preferably used as the connection element to the busbar arrangement according to the invention, at least insofar as it is to be used in two poles (ie with a voltage between the two wires of the perforated cable 2).
  • the plug 3 shown in FIG. 4 in two views rotated by 90 ° relative to one another has a grip part 3.1 made of an insulating material and a plug-in and contact part 3.2.
  • two contact pins 3.2.1 are insulated from one another with a mutual spacing and arranged parallel to one another. Their length corresponds approximately to the thickness of the perforated cable 2.
  • the plug-in and contact part 3.2 has a thickening made of an insulating material which protrudes beyond the contact pins.
  • the incision and contact part of the plug 3 is approximately oval and largely adapted to the shape of the holes 2.4 in the perforated cable 2.
  • the cross section of the thickening 3.2.2 is dimensioned somewhat larger than the cross section of the holes mentioned.
  • the two contact pins 3.2.1 are finally connected to the wires of a two-wire connection cable 3.3.
  • the plug 3 with its plug and the contact part 3.2, aligned longitudinally, inserted into one of the holes 2.4 of the perforated cable 2 previously inserted into the cable duct 1 and then rotated by 90 ° into the position shown in FIG. 5.
  • the two contact pins 3.2.1 are in contact with the locations 2.5 of both wires 2.1, 2.2 of the perforated cable 2 that are exposed through the holes 2.4.
  • the plug 3 Due to the formation of the thickening 3.2.2 at its tip somewhat larger in cross section than the cross section of the holes 2.4, the plug 3 can only be inserted into the holes 2.4 with a certain elastic deformation of the perforated cable 2, in particular from its insulation 2.3. This results in a small expansion of the perforated cable at the plug-in point when the plug is inserted.
  • the two leg strips 1.1 and 1.2 of the cable duct 1 accordingly spring somewhat outwards. Fully inserted, the connector 3 snaps into the perforated cable 2.
  • the thickened tip of the plug 3 can pierce the perforated cable, it is arranged at a sufficient distance from its base strip 1.3, as is also shown in FIG. 1.
  • the distance mentioned is approximately equal to the thickness of the perforated cable itself, there is basically the possibility of inserting a second, similar perforated cable into the cable duct or, for example, of having the ends of two perforated cables overlap with one another in the cable duct for their contacting.
  • the cable duct profiles can be cut and laid practically in any length. Laying can be done in a variety of ways, adapted to every purpose: by screwing, gluing, hanging, fixing with suction cups and the like.
  • holes 1.4 can be provided in the base strip 1.3 of the cable duct 1, preferably at regular intervals. The aforementioned distance between the perforated cable 2 and the base strip 1.3 of the cable duct is also necessary with regard to the space required by the screw heads in this case.
  • the holes 1.4 in the base strip 1.3 are advantageously arranged at the same distance from one another as the holes in the perforated cable 2.
  • the base strip 1.3 can be glued on of the cable duct 1 are provided on the outside with an adhesive layer, preferably covered by a tear-off protective film (not shown). At least when screwing on, the perforated cable is pressed into the cable duct after laying it.
  • the busbar arrangement according to the invention described above is particularly suitable for the construction of low-voltage halogen lighting systems when used with two poles.
  • lamps can be connected directly to the conductor rail arrangement according to the invention.
  • the plug 3 is already sufficiently mechanically fixed after it is inserted into one of the holes in the perforated cable, even if it has not yet been rotated into its contact position.
  • the conductor rail arrangement according to the invention, together with plugs of the type of plug 3 has the advantage that the consumers (lamps) and lines connected to them can be switched on or off at any time without mechanical disconnection from the conductor rail and without a special switch.
  • Fig. 6 shows an arrangement in which three lamps are suspended from a perforated cable 2 of the type described above, each with a plug 3 of the type also described, the perforated cable itself being held only in two relatively short cable duct sections 1, but is otherwise free-hanging .
  • the connecting piece 5 shown in FIG. 7 consists of two contact pins 5.1 and 5.2 tapering on both sides, which in one part 5.3 are parallel to one another insulating material are embedded.
  • the mutual distance between the two contact pins 5.1 and 5.2 corresponds exactly to the mutual distance between the two wires of the perforated cable.
  • This outer shape of the insulating part 5.3 is roughly adapted to the outer shape of the perforated cable.
  • the tips mentioned are preferably still provided with small ribs in order to secure them against slipping out in the wires of the perforated cable.
  • the two contact pins can also be secured against slipping out of the insulating part 5.3 by means of further ribs 5.4.
  • the entire connector 5 can be manufactured as a plastic injection molded part. Since the described connector corresponds in its outer shape to the shape of the perforated cable, it can be pressed into a cable duct together with the attached perforated cables, so that the entire connection has an excellent stabilization.
  • the connector 5 is therefore primarily used to connect two perforated cables within a cable duct.
  • the perforated cable is preferably routed continuously over the joint of two cable ducts.
  • Fig. 8 shows in section a similar connector 6, but in which the insulating part 6.3 over the pointed protruding ends of the two contact pins 6.1 and 6.2 collar-shaped and is formed there so that it fits tightly around the perforated cable ends plugged onto the contact pins 6..1 and 6.2 as described above with the aid of the connecting piece 5.
  • This connecting piece is particularly suitable for connecting two perforated cable ends outside a cable duct, since the ends of the perforated cable are also held mechanically here.
  • the connector 6 could also be adapted to the shape of the cable duct.
  • Fig. 9 shows purely schematically a right-angled connector 7 of the type of Fig. 7. However, this could just as well be adapted to the connector of Fig. 8 and externally to the shape of the cable duct.
  • FIG. 10 shows a lamp which is suspended from two busbars according to the invention, the two busbars, however, each being used only with one pole. There is therefore no voltage between the respective wires of the two perforated cables, but only between the right and left conductor rail arrangement. The wires of the perforated cable are connected in parallel. In this way, the busbar arrangements can also be used for higher voltages, such as 220V, for example. This also results in a doubled conductor cross-section for the current supply.
  • the connector 3 explained with reference to FIG. 4 can be used again for the connection, provided that its two contact pins are short-circuited to one another.
  • FIG. 11 shows a busbar arrangement specially designed for single-pole use with two mutually parallel cable ducts 1a, 1b, each of which contains a perforated cable 2.
  • the two cable ducts 1a, 1b are formed in a uniform profile part.
  • This busbar arrangement is also suitable for higher voltages of, for example, 220V.
  • the busbar arrangement according to the invention can serve well for further technical applications. This is first explained using the example of a crossbar distributor as shown in FIG. 12.
  • the individual rails of the illustrated crossbar distributor which are arranged horizontally or vertically one above the other in two planes, are formed by conductor rail arrangements according to the invention, in each case used with one pole. Connections between an upper and a lower conductor rail can be made at the intersection points arranged in the form of a matrix by means of continuous single-pole plug pins 4 with a round cross section in the manner shown in FIG. 14. This allows inputs A, B and C to be connected to outputs a to d as required.
  • the cable ducts are preferably arranged with their base strips abutting one another. It is understood that for such an application cable ducts with holes provided in their base strip must be used and that the spacing of the holes in the base strip must correspond to the spacing of the holes in the perforated cables.
  • FIG. 13 shows a busbar selector with five vertical busbar assemblies, which in turn are only used with one pole, and two horizontal busbar assemblies lying above them.
  • the perforated cables are interrupted in the middle in the five lower conductor rail arrangements.
  • the upper halves of the interrupted perforated cable lead to outputs a to e, the lower halves to outputs f to j.
  • input A can be connected to one of outputs a to e and input B can be connected to one of outputs f to j.
  • the connection is established in the manner shown in FIG. 14, as previously explained for the crossbar distributor.
  • the busbar arrangement according to the invention can, as explained, for low voltage of e.g. up to only 42 V but also for higher voltages of e.g. 110 or 220 V can be used. In this respect it can be used in electrical laboratories, test rooms, in solar systems, for lighting systems, for connecting lighting fixtures and in general all electrical devices of the corresponding voltage for which the busbar arrangement is intended.
  • the busbar arrangement according to the invention is suitable for halogen lighting systems of 12 V voltage.
