  • connection accessory facilitates the connection of modular row-to-row electrical equipment, particularly in recessed enclosures in which the space available at the rear of the corresponding support rails is relatively limited, as may be for example the case in some distribution and protection boxes, and it can be satisfied congestion constraints that are inevitably overcome in such envelopes.
  • connection accessory according to the invention is advantageously compatible with the various existing combs, whether unipolar combs or whether it is multipole combs.
  • the plane of at least one of the pins that comprises the connection accessory according to the invention is oblique with respect to the electric cable, and, for example, it is so for the one and the other of its two pins.
  • this electric cable is advantageously inclined relative to the rear face of these electrical devices, and therefore, with respect to the bottom of the envelope in which they are disposed and / or the wall on which this envelope is optionally reported.
  • connection accessory is thus still advantageously facilitated, especially when the space available between the support crosspieces and the bottom of the envelope and / or the wall concerned is measured.
  • the electrical cable advantageously knows, from one to the other of these electrical equipment, a more natural and shorter course.
  • these electrical devices 10 are modular electrical devices, such as, for example, circuit breakers.
  • They therefore comprise, one and the other, in a similar configuration, on the one hand, two main faces 11, which are parallel to each other, and by which, as shown schematically in phantom in Figure 6, they can be arranged side by side with other electrical devices 10 of the same type, being in practice reported on the same support beam, not shown, and, secondly, according to their edge, a rear face 12, by which they are adapted to be reported on such a support beam, a front face 13, on the middle part of which protrudes a nose 14, but which, apart from this nose 14, is substantially parallel to the rear face 12, and two lateral faces 15, which are parallel to each other, being substantially perpendicular to the rear face 12, and on at least one of which opens at least one connection terminal 16.
  • connection terminal 16 in this case their face. the upper side, and, on the other hand, that on it, at a distance from one another, two connection terminals 16, namely one of phase and one of neutral, shifted out of alignment. one with respect to the other both perpendicular to the main faces 11 and perpendicular to the rear face 12.
  • busbars 18 are also well known per se, and therefore will not be described in detail here.
  • bus bars 18 are unipolar.
  • At least one connecting accessory 23 is used, from one to the other of the two electrical devices 10 concerned.
  • connection accessories 23 are provided, one for connecting one of the connection terminals 16 of one of the electrical equipment 10 to the terminal of corresponding connection 16 of the other of these, and the other to connect to one another to the other connection terminals 16 of these electrical equipment 10.
  • connection accessories 23 are identical to each other.
  • connection accessory 23 uses an electric cable 24.
  • this electric cable 24 is an insulated cable.
  • the electric cable 24 is a flexible electrical cable, and, together, the connection accessory 23 has, permanently, at each end of this electric cable 24, a flat pin 27, which extends substantially perpendicularly to this electrical cable 24, and which is electrically connected to the conductive core 25 thereof.
  • flat pin 27 is meant, here, in the usual manner, a pin 27 generally having the form of a two-dimensional tab, disregarding any offset from which it may possibly be transversely over a part of its length, as will be described below.

  • this plane P has been shown schematically, in broken lines, by its trace, in Figures 3 and 4.
  • the plane P of at least one of the pins 27 that comprises the connecting accessory 23 according to the invention is oblique with respect to the electric cable 24, and more precisely, with respect to the elongation direction D of this electrical cord 24, this elongation direction D being appreciated in the immediate vicinity of the pin 27, at the connection of the electric cable 24 to this pin 27.
  • the angle A that the plane P of such a pin 27 made with the electric cable 24 under the conditions specified above is between 25 ° and 35 °, being for example of the order of 30 ° .
  • At least one of the pins 27 that comprises the connection accessory 23 according to the invention is in one piece with a lug 31 crimped on the conductive core 25 of the electrical cable 24, forming one and the same piece with this lug 31.
  • this pin 27 and the lug 31 come together from one and the same metal blank 32 suitably cut and folded.
  • At least one of the pins 27 that comprises the connecting accessory 23 according to the invention is folded U-shaped on itself according to its height, on at least part of it, at benefit of its rigidity.
  • the lug 31 is itself formed by two tabs 33 which, coming from a sole 34 belonging to the metal blank 32, are both shaped as a stick, towards this sole 34 and in the direction of one another.
  • the sole 34 of the metal blank 32 is, in practice, with the root 29 of the spindle 27, a dihedral whose angle B is the complement of the angle A that the plane P of this pin 27 with the electric cable 24.
  • At least one of the pins 27 that comprises the connecting accessory 23 according to the invention has its free end 30 which is shifted transversely with respect to its root 29.
