    • H01R25/14—Rails or bus-bars constructed so that the counterparts can be connected thereto at any point along their length

Definitions

  • the present invention relates to a process and means to provide bus bar distributing systems, wherein each bus bar comprises more uniform cross-section components, set to receive, anywhere, therealong, a number of terminals and the like, limited only by the principle of impenetrability of bodies.
  • the bus bars of distributing and/or collecting electrical energy, providing for the connection of terminals and the like are individual and are rectangular in cross-section.
  • the longer side of their rectangular cross-section is from three to six times as longer as the shorter side thereof.
  • Such rectangular cross-section bars are drilled and tapped with mating threads, through their main surfaces, to receive the machine screws for terminal and connection fastening.
  • the tapped holes are provided correctly, in number and position. Instead, when use and density of connections or terminals are unknown, the holes are provided according to an estimated modular rule, and more frequently, in accordance with a statistical probability.
  • the uniform cross-section components substantially comprising each bar unit, are five, three of which are electric conductors and two are non-conductors.
  • Two of the three conductor components, the bus bars, provide the parallel walls which can be engaged by the screws, fastening the terminals and the like; the third conductor component and the non- conductor components, act as encompassing members.
  • the conductor component is in centripetal position, in touch with the single bars or parallel walls, which can be engaged by the screws, fastening the terminals and the like and the non- conductor components, having "L" like cross-section, are in centrifugal position which is complementary to that of the encompassing conductor component;
  • the former component is a channel, which is provided, at the centre of its bottom, with a separating rib, providing, at its sides, a pair grooves, to receive the single conductor bars.
  • the paired parallel single bars set with the longer side in vertical disposition, minimizes the overall dimensions thereof, while their surface area results increased.
  • Insulation is provided by components of higher height, which are arranged in stepped fashion and extend over the single bars. They are placed at least at one side, or on both side in case of adjacent bar units, to provide here too, mainly in vertical direction, the necessary dielectric distance, with a minimum of overall dimensions.
  • cross-section of the conductor encompassing component is additional to the cross-section of the single bars, to provide, coeteris paribus , a compacted ensemble.
  • each bus bar unit of the cross-section between 200 and 800 mm2
  • two single bars of copper between mm 5 x mm 20 and mm 5 x mm 80 contained by an aluminium channel rod length of the dimensions of mm 17,5 x mm 20 x mm 2,5, are provided.
  • the single bars standing with the short side of the rectangular cross-section against the inner bottom of the channel, are fit aside the rib, in order to provide their adjacent main surfaces parallel, at a distance of mm 5.
  • This distance is correct to receive any so said "Parker” screw or equivalent, having an outer diameter of mm 6,3, and a length between 20 mm and 40 mm, i.e. shorter than the corresponding dimension of single bars.
  • Such screws are duly provided with lock washers and applied to terminals and the like, whereby they cut their own thread into the single bars of copper, along an height L concerned between mm 18 and mm 38.
  • the so fastened terminal provides a contact in at least four spots, with a conductivity increase of about 80%.
  • a binding frame is provided substantially comprising two "Y" like uniform cross-sectioned rod components, fit longitudinally, which are a materialization too, of the principle of the present invention, being adapted to receive self-tapping screws in any cross-section thereof.
  • This arrangement is very important also from the electric point of view, since as material, one with a good conductivity, such as aluminium, is chosen, to be adapted to connect, by self-tapping screws, driven into the more grooves, of which they are provided, the grounded terminals.
  • the rods with uniform cross-section providing the binding structure, can be connected, crosswise, at the bottom by screws, i.e., self-tapping screws, engaging the ends of a distancing rod, it too comprised by uniform cross-section rods.
  • screws i.e., self-tapping screws
  • the structural components rods are connected through staples, thickness, self-tapping screws and bridges, all of them, except the screws, comprised by uniform cross-section rods.
  • Each bus bar unit comprises more component rods 1, 1', 2, 3, 3, all of them having uniform cross-section, set to receive, anywhere, therealong, a number of adjacent terminals 9 and the like, limited only by the principle of impenetrability of bodies.
  • the uniform cross-section components are five 1, 1', 2, 3, 3. Three of them: 1, 1', 2, are conductors and two, 3 non conductors.
  • the two conductor components 1, 1' provide the parallel walls 10, 10', which can be engaged by the screws 5, fastening the terminals and the like and the third conductor component 2, and insulator components 3, provide encompassing functions: the conductor member 2 is in centripetal position, in touch, even through the rib 2', with the single bars 1,1' or parallel walls 10, 10' which can be engaged by the screws 5, fastening the terminals 9 and the like; the insulator components 3 are in centrifugal position which is complementary to that of enveloping conductor component 2; the former 2 having "U” or "C” or channel like cross-section, the latter 3 having "L” like cross-section.
  • the insulation space between bar units 01, 02, 03, 04, is provided by components 3 of higher height; they are coupled in stepped conditions and project from the upper side of single bars 1, 1'; they are fit paired to adjacent bar units 01, 02, 03, 04, to provide here too, mainly in vertical direction, the necessary dielectric distance with minimum overall dimensions.
  • the cross-section of the enveloping conductor component 2 is additional to the cross-section of the single bars 1, 1' to provide, coeteris paribus a compacted unit.
  • each bus bar unit 01, 02, 03, 04, of the cross-section of 200 mm2 were used two copper rectangular single bars 1, 1', of mm 5 x mm 20, contained by an aluminium channel rod 2, of the dimensions of mm 17,5 x mm 20 x mm 2,5, whose inner bottom 2'', 2''' is provided with a central rib 2', which is mm 5 width and mm 3 height.
  • the single bars 1, 1' standing with the short side of the rectangular cross-section against the inner bottom of the channel rod 2, are fit, respectively into the grooves 2'', 2''', aside the rib 2', in order to provide their adjacent main surfaces 10, 10', parallel at a distance corresponding to that of rib 2' i.e., of mm 5.
  • This distance is correct to receive any of so said "Parker” screws 5 or equivalent, having an outer diameter of mm 6,3, and a length of 20 mm, i.e. shorter than the corresponding dimension of single bars 1, 1'.
  • Such screws 5, are duly provided with lock washers 6 and applied to terminals 9 and the like, in order that the same screws 5 cut their own thread into the single bars 1,1' of copper, along an height L concerned of mm 18.
  • the so fastened terminal 9, provides a contact in at least four spots 09, with a conductivity increase of about 80%.
  • each bus bar unit 01, 02, 03, 04 having a cross-section of 500 mm2 were used two copper rectangular single bars 1, 1', of mm 5 x 50, contained by an aluminium channel rod 2, of the dimensions of mm 17,5 x mm 20 x mm 2,5,whose inner bottom is provided with a central rib 2', which is mm 5 width and mm 3 height.
  • the single bars 1, 1' standing with the short side of the rectangular cross-section respectively on the bottom 2'', 2''' of the grooves siding the rib 2' of channel rod 2, in order to provide their adjacent main surfaces 10, 10' parallel at a distance corresponding to that of rib 2' i.e., of mm 5.
  • the ensemble 3, 01, 3,3, 02, 3,3, 03, 3,3, 04, 3 is bound with an annular frame 7 comprised by a pair of uniform cross-section rod lengths 70,70', having, in general, a "Y" like cross-section, connected crosswise, at the bottom by screws, i.e., self-tapping screws 71, 71', engaging the ends of a distancing rod 72, it too comprised by uniform cross-section rods.
  • the structural components rod lengths 70, 70' are connected through staples 73, thickness 74, self-tapping screws 75 and bridges 76, all of them, except the screws 75, being comprised by uniform cross-section rods.
  • rod components 70, 70', 72 i.e. for all connections 9, all over the whole system, they may be made anywhere, limited only by the principle of impenetrability of bodies.
  • the fastening screws 5 and the grooves 00 there is the same arrangement than between the fastening screws 5 and channel 101 provided with walls 10, 10' for terminal fastening.
  • grooves 00 are adapted for grounded conductors terminals 9 (figures 4 and 5) which can be fastened with screws 5.
  • the same grooves 00 may be used for structural binding as in the case of screws 71, 71', 75.
