Definitions

  • the present invention relates generally to comb-shaped supply bars of the type used for example for the joint service of a plurality of modular electrical devices aligned side by side on the same support.
  • these supply bars comprise, transversely, from place to place, in a regular pitch, a plurality of teeth, by which they are adapted to engage with the relevant connection terminal of these modular electrical appliances or, at least, that of some of them.
  • the present invention relates more particularly to the arrival terminal which it is usual to associate with such a power bar to ensure its own connection to an electrical conductor capable of connecting it to any power source.
  • This arrival terminal includes, in particular, a conductive active part and this itself comprises, on the one hand, a connection pad, which, to allow the engagement of an electrical conductor to be connected, has at least a conductor input, and, on the other hand, a conduction tab, which, in particular when the sill of the power bar is protected by an insulating sheath, is intended to be superimposed, at least locally, on a tooth of this power bar, for contact with this tooth and joint engagement with it in the corresponding connection terminal of any of the modular electrical devices concerned.
  • Inbound terminals of this type known to date generally have the disadvantage of offering no choice for the possibility of implantation of their conduction tab relative to the tooth of the power bar to which it this must be superimposed, which in practice limits their field of application to this or that type of connection terminal for modular electrical devices concerned.
  • the present invention generally relates to an inlet terminal for a comb-shaped power bar free from this drawback.
  • This arrival terminal which is of the kind set out above, is generally characterized in that, the conduction tab of the active part successively comprising two sections from the connection pad, namely, a section root and an end section, the end section has a thickness greater than that of the root section.
  • the conduction tab of the arrival terminal according to the invention can be superimposed either above or below on a tooth of the supply bar, despite the thicknesses of insulation possibly present on the sill this feed bar, and / or on its own root stretch.
  • the incoming terminal according to the invention is therefore suitable both in the case where the corresponding connection terminal of the modular electrical appliance concerned is a terminal of the so-called plate type, and in the case where it is a terminal of the so-called elevator type, which advantageously increases its field of application accordingly, and which advantageously facilitates its re-use during a possible modification of the installation in which it operates.
  • the arrival terminal 10 is intended to be associated with a power bar 11, which, in the form general comb, comprises, on the one hand, a sill 12, and, on the other hand, coming transversely from place to place of this sill 12, in a regular pitch, teeth 13.
  • a power bar 11 which, in the form general comb, comprises, on the one hand, a sill 12, and, on the other hand, coming transversely from place to place of this sill 12, in a regular pitch, teeth 13.
  • the sill 12 of the supply bar 11 is surrounded by an insulating sheath 14.
  • the arrival terminal 10 comprises an active part 16, which is conductive, and which, in the embodiment shown, is at least partly coated by an insulating envelope 17.
  • This active part 16 itself comprises, on the one hand, a connection pad 18, which, to allow the engagement of an electrical conductor 19 to be connected, is present at the right of an opening 20 of the insulating envelope 17, at least one conductor input 21, and, on the other hand, a conduction tab 22, which, intended to be superimposed, at least locally, according to methods described in more detail later, on a tooth 13 of the bar supply 11, for contact therewith, protrudes from the insulating envelope 17.
  • the active part 16 also includes a clamping screw 23 intended to cooperate in screwing with a threaded bore 24 of the connection pad 18 which transversely intersects the conductor inlet 21 thereof.
  • connection pad 18 of the active part 16 has two conductor inputs 21, and the insulating envelope 17 comprises, jointly, in correspondence, two openings 20.
  • connection pad 18 extends on either side of its threaded bore 24, opening one and the other therein. , and they are therefore aligned back to back in an alignment direction D1 with respect to which the conduction tongue 22 extends transversely.
  • the alignment direction D1 of the two conductor inputs 21 is perpendicular to the plane passing through this axis A and by this direction of elongation D2.
  • the conduction tongue 22 of the active part 16 comprises, successively, from the connection pad 18, two sections, namely, a section of root 28, by which it is connected in one attached to this connection pad 18, and an end section 29, by which it is intended to come into contact with a tooth 13 of the feed bar 11.
  • the root section 28 extends at mid-height of the connection pad 18, perpendicular to the corresponding face thereof, along a width L1, which, in practice, is equal to that of this face.
  • the end section 29 extends along a smaller width L2, while being centered relative to the root section 28.
  • this end section 29 a perpendicular to the following direction which it must be applied to a tooth 13 of the feed bar 11, a thickness E2 greater than that E1 of the root section 28.
  • the end section 29 comprises, with respect to the thickness E1 of the root section 28, an extra thickness E'2, E “2 on either of its two main faces 30, 31, that is to say on one and the other of the two faces which extend perpendicular to the direction in which it is intended to be superimposed on a tooth 13 of the feed bar 11.
  • the extra thickness E'2 on the upper main face 30 of the end section 29 is greater than the extra thickness E "2 on its lower main face 31.
  • the direction in which the end section 29 is intended to be superimposed on a tooth 13 of the feed bar 11 is parallel to the axis A of the threaded bore 24 of the connection pad 18.
  • one and the other of these main faces 30, 31 are each connected respectively by a chamfer 32, 33 to the root section 28.
  • the root section 28 has a rectangular outline elongated in the alignment direction D1 of the conductor inputs 21 of the connection pad 18, while the end section 29 has a substantially square outline.
  • the conduction tongue 22 is generally rectilinear.
  • this conduction tab 22 is in one piece with the connection pad 18.
  • the assembly can for example be very simply constituted by a section of profile duly cut and machined.
  • the insulating envelope 17 does not fall under the present invention, it will not be described in detail here.
  • the conduction tongue 22 does of course project therefrom, that, however, it has two lateral extensions 35, 36, one upper, the other lower, by which it is capable of enclosing the section of root 28 of this conduction tongue 22, that, to give access to the clamping screw 23, it has a well 38, and that, with each of its openings 20, there is associated a closing flap 39.
  • the lower lateral extension 36 of the insulating envelope 17 is articulated to its upper lateral extension 35 by a hinge zone 40 parallel to the conduction tongue 22.
  • these latching means comprise, on the one hand, projecting from the upper lateral extension 35, on the side of the latter opposite the lower lateral extension 36, a rib 41, and, on the other hand, projecting from the lower lateral extension 36, on the side of the latter opposite the upper lateral extension 35, a tab 42, which, perforated in the form of a loop, is capable of being hooked on the rib 41.
  • the conduction tab 22 of the active part 16 of the arrival terminal 10 according to the invention is superimposed, by its end section 29, on a tooth 13 of the supply bar 11.
  • connection terminal 44 in which the assembly is to be engaged is of the elevator type, this superposition takes place from below, that is to say on the side of the underside of the tooth 13 concerned of the feed bar 11.
  • a connection terminal 44 of the elevator type comprises, on the one hand, a fixed contact element 45, on which the corresponding tightening screw 46 is supported, and, on the other hand, a movable contact element 47, which, in the form of a stirrup, surrounds the fixed contact element 45, and with which the clamping screw meshes, and the elements to be tightened must be engaged between the fixed contact element 45 and the strand of the movable contact element 47 opposite to that with which the clamping screw 46 meshes.
  • the extra thickness E'2 which has on its upper main face 30 the end section 29 of the conduction tongue 22 allows this conduction tongue 22 to contact the tooth 13 of the feed bar 11 despite the presence of the thicknesses of insulation due, on the one hand, to the insulating sheath 14 of the supply bar 11, and, on the other hand, to the upper lateral extension 35 of the insulating envelope 17 of the arrival terminal 10.
  • the root section 28 of the conduction tongue 22 of the inlet terminal 10 is advantageously completely insulated, on its upper face, by the supply bar 11 and by the lateral extension 35 upper of the insulating jacket 17, and, on its underside, by the lower lateral extension 36 of this insulating jacket 17, for the benefit of safety.
  • connection terminal 44 is of the plate type, the superposition, on a tooth 13 of the supply bar 11, of the end section 29 of the conduction tongue 22 of the arrival terminal 10 according to the invention, is done from above.
  • a connection terminal 44 to wafer comprises, as previously, a fixed contact element 45, but the associated tightening screw 46 meshes with a fixed part 47, which can for example be constituted by a surrounding stirrup as before, the fixed contact element 45, and it carries with it a plate 48, which has passed under the free end of its barrel, and which it is responsible for bringing closer to the fixed contact element 45, and elements to tighten are to be engaged between this plate 48 and this fixed contact element 45.
  • the lower lateral extension 36 of the insulating envelope 17 is detached from the upper lateral extension 35 and left open.
  • the root section 28 of the conduction tongue 22 is advantageously insulated in its entirety, on its upper face, by the upper lateral extension 35 of the insulating envelope 17, and, on its lower face, by the bar d 11.
