  • each metal insulation contact member 140 comprises a rectilinear slot whose mouth 143 is flared, the bottom 142 is rounded and the edges 141 are sharp.
  • each insulative metal contact element 140 is held by the insulating envelope constituted by the base 101 so that its slot emerges on the rear face of the base 101 to be accessible to an electrical conductor.
  • the two slots of a pair of insulation displacement metal contact elements 140 are placed opposite each other so that a single electrical conductor 10, 11, 12 through can be forced into said slots simultaneously to make electrical contact with the metal core of said conductor at two different locations along it.
  • each insulation displacement metal contact element 140 of the same electrical connection terminal to connect two different electrical conductors cut at their end, namely, a supply conductor and a transplanting conductor for each of the slots of said insulation displacement metal contact elements.
  • the electrical equipment 1 comprises three connection levers 110, 120, 130 pivotally mounted on the base 101 of the fitting mechanism. 100, between a raised position and a folded position on the base 101.
  • connection levers 110, 120, 130 allow, during a pivoting movement or tilting from their raised position to their folded position, to force insert the electrical conductors 10, 11, 12 in the slots of the metal insulation contact members 140 of the electrical connection terminals.
  • connection levers 110, 120, 130 are arranged relative to each other so as to impose on the installer an order of operation of said levers for making the electrical connections between the electrical conductors and the connection terminals of the electrical equipment 1.
  • one of the three connection levers is placed in a central zone of the rear face of the base 101, close to one of the two other connection levers 110 situated along an edge of the base, so that in the raised position, said keying lever 120 forms an obstacle which prevents this other connecting lever 110 from folding on the base 101.
  • connection lever 110 and said polarizing lever 120 are aligned and said other connection lever 110 has a length l greater than the distance d provided between its pivot axis and the pivot axis of said keying lever 120 so that in the folded position said other lever 110 extends partly above said keying lever 120 in alignment thereof (see figures 1 and 3D ).
  • the second of the two other connection levers 130 is placed along an edge of the base 101 opposite the edge along which is placed the first other connection lever 110.
  • the said keying lever 120 and the second 130 of the two other connecting levers are offset relative to each other while being positioned symmetrically so that in the folded position, the keying lever 120 and this other connecting lever 130 are placed side by side, head- spade (see Figures 3A to 3D ).
  • Said polarizing lever 120 and second second connecting lever 130 have lengths greater than or equal to half the width of the base 101. Thus, in the folded position on the base 101, the free end of the keying lever 120 arrives at edge of the base 101.
  • Each connection lever 110, 120, 130 comprises at least one arm 111, 112, 121, 122, 131, 132 associated with an insulation displacement metal contact element 140, each arm 111, 112, 121, 122, 131, 132 having a width which decreases from a mounting portion 111A, 112A, 121A, 122A, 131A, 132A wide connected to a hinge pin 115, 125, 135 to an operating portion 111B, 112B, 121B, 122B, 131B, 132B narrow.
