Definitions

  • the present invention refers to an improved connector device for electrical connection of electrical panel terminals, a method for obtaining such connector device, an electrical connection group provided with such improved connector device and an improved connector group comprising a plurality of improved connector devices.
  • the abovementioned invention regards making removable electrical groups and connections suitable for transverse connections in a terminal board, typically for electrical panels for power distribution.
  • electrical panels for power distribution comprise a plurality of pairs of modular terminals arranged adjacent to each other and provided with connection units for the appliances served by the panel itself.
  • Each respective pair of terminals is generally made up of conductor bodies usually contained in insulating bodies, and narrow inlet and outlet spaces for the electrical connections.
  • each pair of terminals is achieved by connecting two conductor bodies, generally a perforated plate accommodated in a first terminal and a rod element projecting from the second terminal which, during use, is inside the abovementioned hole to attain the passage of current between the related terminals.
  • Such connections must ensure a stable and efficient electrical contact, with shape constraints between holes and the relative rods which, cooperating with each other, must stably maintain a relative contact to ensure both the proper assembling position of the pair of terminals and an efficient electrical conduction.
  • both the perforated plate and the relative rod elements are independent from each other but made in a single piece passing transversely through all the pairs of terminals ending up forming the so-called "parallel bridges".
  • An object of the present invention is that of providing a device capable of overcoming the abovementioned drawbacks of the prior art in an extremely simple, inexpensive and particularly functional manner.
  • Another object is that of obtaining an improved connector device for electrical connection between electrical terminals capable of guaranteeing a firm assembling position for the relative pair of terminals as well as an efficient electrical conduction between the terminals themselves.
  • Another object is that of obtaining an improved connector device for electrical connection between electrical terminals smaller in size and with a structure having a high elasticity.
  • Another object is that of obtaining an improved connector group, or a "parallel bridge", comprising a plurality of improved connector devices subject of the present invention capable of overcoming the drawbacks regarding connections of groups of parallel terminals of the prior art i.e. independent from the number of pitches of the electrical panel to be connected and allowing an easy, stable and efficient installation of the electrical panel itself.
  • Another object is that of providing a quick and efficient method for obtaining the connector device subject of the present invention.
  • Another object is that of obtaining an electrical connection group, or electrical panel, provided with at least one connector device subject of the present invention.
  • reference number 10 indicates an improved connector device for the electrical connection between electrical terminals
  • reference number 100 indicates an electrical connection group provided with such improved connector device 10
  • reference number 102 indicates an electrical panel provided with an improved connector group 101 comprising a plurality of improved connector devices 10 in parallel.
  • the abovementioned improved connector device 10 of the present invention in particular suitable to establish the conduction continuity between two different terminals 11, 11' of an electrical panel, is shown according to a preferred embodiment in figure 1 and it is obtained from a band 20 made of electrically conducting material, generally a high copper content alloy.
  • Such connector device 10 substantially develops in longitudinal direction and comprises a first 12 and a second 13 end which are substantially located at the same level.
  • the connector device 10 comprises a central portion 14 provided with a three dimensional and highly elastic structure.
  • Such high elasticity directly derives from the same geometry of the central portion 14 which is provided according to the invention with at least three thin bars 15, 15', 15" which start from the first end 12 and meet in the second end 13.
  • the geometry of the central portion 14 confers the connector device 10 a high elasticity which, advantageously, allows using highly conductive materials as well as reducing the dimension of the connector device 10 itself without jeopardising the overall elasticity of the object of the present invention.
  • the connector device 10 may be obtained from a high copper content metal section coated with tin on the two opposite faces.
  • the three bars 15, 15', 15" of the connector device 10 may comprise a substantially square-shaped or parallelepiped section in which the external edges 35, as observable in figure 10 and 11 , have a rounded shape and are protected by a tin coating, in such a manner to prevent the oxidation of the contact point and have a greater electrical transmission efficiency.
  • the method according to the present invention for the making of a connector device 10 as described previously solely comprises the steps of cutting and cold deformation of a band 20 of electrically conducting material.
  • the abovementioned knives/punches 60, 60', 62, 62', 61 advantageously perform a plastic dragging of the protective tin layers on the turned in part of the cutting surface, as shown for example in figure 10 .
  • the connector device 10 is particularly advantageous for the electrical connection of said two terminals 11, 11' to obtain an electrical connection group 100 of the type shown in figures 3 and 4 .
  • Such electrical connection group 100 comprises at least one first and one second terminal 11, 11' to be electrically connected and at least one connector device 10, as described previously, which electrically connects the abovementioned two terminals 11, 11'.
  • the first end 12 of the connector device 10 is constrained in a substantially non-accessible manner inside the first terminal 11 while the second end 13 is accessible and extended outwards from the first terminal 11 itself.
  • each bar 15, 15', 15" is in contact with the hole 20.
  • the hole 20 is an end of an element 21 made of electrically conducting material arranged at least partially inside the second terminal 11'.
  • the hole 20 is preferably circular-shaped and the distance - when idle - between the opposite peripheral edges of the three bars 15, 15', 15" exceeds the value of the diameter of the hole 20 in the range of 0.1-1 mm.
  • the abovementioned “interference” range may also vary between 0.2-0.4 mm.
  • the three bars 15, 15', 15" which form the central portion 14 have the external edges 35 lying, when idle, at a mutual distance greater than the diameter of the hole 20 which is to receive the three bars 15, 15', 15" themselves.
  • the bars 15, 15', 15" are thus elastically deformed and exert three reaction forces in direction opposite to the forced approaching of the bars themselves.
  • constriction forces of the bars 15, 15', 15" are directed according to the contact diameter, identical and opposite to the reaction forces of the bars, thus ensuring contact.
  • the circular shape of the hole 20 is preferred since it is capable of ensuring that the insertion of the three bars 15, 15', 15" occurs with a deformation that is constant and independent from the orientation of the three bars 15, 15', 15" themselves with respect to the axis of the hole.
  • an improved connector group 101 or "parallel bridge", comprising a plurality of connector devices 10 parallel to each other.
  • this improved connector group 101 shown in figures 12 and 13 during different steps of use, comprises a common first end 12 from which a plurality of said central portions 14 ending in relative second ends 13 develop parallel to each other.
  • Such improved connector group 101 allows connecting a plurality of electrical connection groups 100 to obtain an electrical panel 102 independently from the number of pitches separating the terminals to be used of the electrical panel 102 itself.
  • the common first end 12 provided for can be weakening grooves which facilitate the separation of some devices 10 to prepare the parallel bridges of the desired pitch as observable in the example of figure 13 .
  • the connector device 10 as described previously comprises a first 12 and a second 13 end substantially arranged at the same level and a central portion 14 between such ends 12, 13 comprising a three dimensional and elastic structure provided with at least three thin bars 15, 15', 15" that start from the first end 12 and meet in the second end 13.
  • the connector device 10 of the present invention allows obtaining an improved connector group, or "parallel bridges", comprising a plurality of devices 10, independently from the number of pitches separating the various terminals in use in an electrical panel.
  • provided for at the common first end 12 can be weakening grooves which facilitate the separation of some devices 10 to prepare parallel bridges of the desired pitch.
  • an improved connector device for electrical connection between electrical terminals a method for obtaining such connector device, an electrical connection group provided with such improved connector device and an improved connector group comprising a plurality of improved connector devices according to the present invention attain the objects outlined previously.
  • the improved connector device for electrical connection between electrical terminals the method for obtaining such connector device, the electrical connection group provided with such improved connector device and the improved connector group comprising a plurality of improved connector devices of the present invention thus conceived are susceptible to numerous modifications and variants, all falling within the same inventive concept; furthermore, all details can be replaced by technically equivalent elements.
  • the materials used, as well as dimensions thereof and the protective coating may vary depending on the technical requirements.
