Definitions

  • the present invention relates generally to the field of electrical terminal blocks and connection bars for these terminal blocks.
  • the invention finds a particularly advantageous application in the production of an electrical terminal block.
  • Such an electrical terminal block comprises a plurality of electrical connection terminals for performing a tap-in for supplying different electrical devices.
  • the tap-in is performed using an electrical wire of conventional cross-section: the electrical terminal block comprises for this purpose a plurality of electrical wire inlets of a size suitable for the passage of these electrical wires, for example with a cross-section approximately equal to 10 square millimeters (mm 2 ).
  • the electrical terminal block further comprises, for its connection to the electrical network, at least one inlet suitable for receiving an electrical supply cable with a cross-section larger than that of the electrical wires, for example with a cross-section greater than or equal to 16 mm 2 .
  • Such an electrical terminal block is known for example from the document EP0814540 It has the disadvantage of having low modularity: the number of electrical cable entries and their positions are predetermined and cannot be modified.
  • This connecting bar comprises a body provided with two longitudinal ribs together forming a slide adapted to receive a stirrup.
  • This stirrup comprises two branches whose ends are provided with open grooves facing each other which allow the stirrup to be slid onto the slide of the connecting bar.
  • the stirrup forms an additional connection terminal adapted to receive a connection cable of larger cross-section.
  • the present invention proposes a new connection bar allowing modularity in the number and location of the terminals accommodating an electric cable of larger section and which can be manufactured by a simplified process with a reduced quantity of material.
  • the invention provides a connecting bar as defined in claim 1.
  • the user can place the connecting cage in place of any location of a connection housing of the body of the connecting bar to connect an electrical cable of larger cross-section.
  • the body of the connecting bar does not require any special arrangement to receive the connecting cage.
  • a standard parallelepiped body not comprising mounting means for the connecting cage can be used.
  • all the connection housings of the connecting bar can be drilled in the same way, with a mouth of the same size, which simplifies the manufacturing process.
  • the quantity of material used to manufacture the connecting bar is also limited.
  • the invention further relates to an electrical terminal block as defined in claim 7.

  • the body 50 of the connecting bar 40 is made for example of brass. It extends along a longitudinal axis X and has a generally parallelepiped shape, with a first and a second longitudinal external face 51, 52 parallel to each other and a third and a fourth longitudinal external face 53, 54 perpendicular to said first and second external faces 51, 52 ( figures 3, 4 , 6 And 8 ).
  • the connecting bar 40 has, in cross section, a square or rectangular outline.

  • the body 50 is pierced with a plurality of orifices 55 ( figures 3, 4 And 7 ) delimiting connection housings which extend along transverse axes Y parallel to each other and perpendicular to the longitudinal axis X. These orifices 55 are through and open onto two openings 55A formed in the first and second external faces 51, 52 of the body 50 ( Figures 3 and 4 ).
  • Each mouthpiece 55A has a circular outline and each orifice 55 is delimited by a cylindrical internal face 55B whose longitudinal axis is the transverse axis Y of the corresponding connection housing ( Figures 3 and 4 ).
  • connection housings are blind. These orifices then only open onto one of the first and second external faces of the body of the connection bar.
  • the orifices and their mouths may also have any other suitable shape.
  • the orifices 55 of the body 50 of the connecting bar 40 are regularly spaced along the longitudinal axis X of the connecting bar.

  • the clamping screw 67 nevertheless conventionally comprises a head 67A and a threaded body 67B ( Figure 4 ).
  • the clamping screw 67 screwed into said tapped holes 62B, 63B and into said tapped conduit 56 ensures the maintenance of the connection cage 60 attached to the body 50.
