  • an “insulation piercing” electrical connection element is intended to make an electrical connection between an electrical device and an electrical wire comprising a conductive core surrounded by an insulating sheath.
  • the cutting edge of the insertion slot pierces the insulating sheath of the electrical wire and comes into contact with the conductive core of the electrical wire.
  • the slot for introducing the connection element must thus be flexible enough to allow easy insertion of the electric wire while maintaining sufficient pressure on the conductive core of this electric wire to ensure good electrical contact between the stripped core. wire and the cutting edge of the slot for introducing the connection element in order to have the lowest possible contact resistance and to avoid overheating.
  • connection element must ensure good transmission of the electric current from the electric wire thus connected to the electrical operating elements of the equipment provided with this electrical connection element.
  • connection element has a compact shape allowing its use in a small space.
  • connection element which however has the drawback of being made entirely from a material having high electrical conductivity, which makes it expensive to manufacture.
  • the document GB1276449 relates to a clamping member for connecting electrical conductors without stripping them first.
  • the latter member is defined as consisting of three tabs forming two clamping slots arranged side by side, which can be independent of each other both as regards the elastic properties of the material and its thickness.

  • This wall 238 forms a stop for the electric wire and ensures that the latter does not obstruct the receiving cell formed at the level of the window 234.
  • the fourth embodiment it is the rear part 331B of the support branch 331 which extends parallel to the functional branch 332, on the same side of the base 331A as this functional branch 332, and thus forms an obstacle preventing the passage of the electric wire through the connection element when it is inserted into one of the slots of this connection element.
  • the introduction of the second electric wire 2 is done in a similar manner.
  • the central part of the element electrical connection is made of a material having high electrical conductivity, which is economical.
  • the peripheral part of the electrical connection element is made of a material different from that of the central part, it is possible to improve the reliability of the electrical connection element by using, for this peripheral part, a less good conductor material, but having mechanical qualities ensuring effective clamping of the electric wire between the edges of the corresponding slot.
  • the lateral wings of the peripheral part may not be parallel to each other at rest, that is to say in the absence of an electric wire inserted into the connection element.
