Definitions

  • the present invention relates to the technical field of crimping tools for crimping electrical contacts.

  • It aims in particular a positioning device for accurately positioning an electric crimp contact on a crimping tool.
  • Crimping tools for crimping electrical contacts are already known.
  • the crimping tools are equipped with positioners, which receive the active parts of the electrical contacts, in order to position these electrical contacts.
  • the crimp electrical contacts may be male contacts or female contacts, the female contacts having an active portion diameter substantially greater than the active portion diameter of the male contacts.
  • the male contacts and the female contacts all have collars of the same dimensions. It is therefore necessary to have, for each series of contacts, two separate positioners, one adapted to the active parts of the male contacts and the other adapted to the active parts of the female contacts.
  • crimping tools equipped with turrets on which are positioned positioners of different sizes, generally three positioners.
  • the presence of these turrets makes it possible to move more quickly from one to the other of the positioners they comprise, rather than to manipulate different individual positioners. But it has emerged that such turrets are bulky, they weigh down the crimping tool on which they are installed, and the number of positions of positioners on these turrets is limited.
  • An example of crimping tool equipped with turrets is described in the document DE 42 09 529 .
  • the present invention aims to overcome the disadvantages mentioned above.

  • said support is in the form of a disc having an axis.
  • said support elements are distributed on a circular line centered on said axis.
  • the positioning device comprises locking means for locking said support relative to the crimping tool.
  • the means for locking the support relative to the crimping tool comprise notches provided on said support. In particular, said notches are distributed over the periphery of said support.
  • said support generally has a plate shape, and each support element comprises a cylindrical hole through said support, said hole having a transverse shoulder.
  • said hole has a first hole portion and a second hole portion extending on each side of said transverse shoulder, the first hole portion having a first diameter and a height and the second hole portion having a second lower diameter. at the first diameter, and said first diameter and said height are substantially equal, respectively, to a given diameter and to a given collar height.
