Definitions

  • the subject of the present invention is a method of crimping an end of a conductor core into a contact element having a front contact part and a rear crimp part provided with an opening into which the end of the contact is introduced. driver's soul.
  • the subject of the present invention is a method making it possible to largely avoid the aforementioned drawback, a method the basic idea of which is to increase the contact surface by a shrinking operation by spinning allowing the rupture of a layer.
  • insulating oxide possibly present for example in the case of a conductive aluminum core.
  • the opening is advantageously frustoconical.
  • the opening advantageously has at least one projecting region intended to be imprinted in said end of the conductor core, this projecting region preferably being a thread.
  • the opening advantageously has a projecting region which is preferably a thread.
  • a device for implementing the method according to the invention comprises front jaws 10 comprising an upper half-jaw 11 and a lower half-jaw 12.
  • the upper half-jaw 11 has a front part comprising a flat face 13 and a rear part 15 oriented in the general direction perpendicular to the front part 13 and having two lateral wings 18 directed downwards, separated by a lower flat face 50 in which is formed a half-footprint 51.
  • the lower half-jaw 12 has a front planar face 14 oriented in a general direction perpendicular to a front plate 16 which has an upper face 60 in which is formed a footprint 61.
  • the device has a pair of rear jaws 20 comprising an upper half-jaw 21 and a lower half-jaw 22.
  • the half-jaw 21 has a front part 23 comprising a flat front face 25 and which, at its lower part, a flat face 70 in which a half-cavity 71 is formed.
  • the lower half-jaw 22 has a front region 24 bordered by a flat front face 26 and an upper flat face 80 in which is formed an imprint 81. It will also be noted that the spacing of the rear half-jaws 21 and 22 takes place along one or more cylindrical guide elements 29 oriented in a generally vertical direction.
  • the indentations 51 and 61 formed in the front half jaws, respectively 11 and 12, have a front semi-cylindrical region, respectively 52 and 62, whose contour is complementary to the front end 8 and the contact end 1, a flared region 53, 63 which is complementary to a retaining flange 7 of the contact element 1, and a second semi-cylindrical region 54, 64 corresponding to all or part of the neck region 5 of the element contact 1, neck region which connects the collar 7 to the rear frustoconical region 4, which has an opening 9 intended for crimping the core 2, for example an aluminum conductor, of a cable 3.
  • the half-impressions 71, 81 of the rear half jaws, respectively 21 and 22, comprise a frustoconical region, respectively 72, 82, corresponding at least to part of the frustoconical region 4 of the contact element 1.
  • the frustoconical region 72, 82 is extended towards the rear, possibly by a semi-cylindrical region, respectively 73, 83, in which the cable 3 can be housed.
  • the method according to the invention can be implemented in the following manner (see FIGS. 2a to 2d):
  • the contact element 1 is arranged so as to be housed in the half-cavity 61 of the lower half-jaw 12, the flange 7 coming to be housed in the flared region 63 and the contact end 8 coming to be housed in the region 62. It can also be seen in FIG. 2a that the end 2 to be crimped has also been introduced into the opening 9 until the sheath 3 of the cable comes into abutment against the rear face 95 of the contact element 1.
  • the frustoconical region 4 is also housed in the frustoconical half-imprint 82 of the rear jaw 22.
  • the frustoconical part 4 is folded down by spinning, and has an approximately cylindrical external profile.
  • the frusto-conical rear part 4 has an interior contour that is also frusto-conical 91.
  • This interior profile 91 has projecting regions 92 which are here constituted by a thread, the thread 92 being printed in the 'core 2 of the conductor, which further increases the contact surface and allows effective rupture of the insulating oxide layer, in particular in the case of an aluminum core 2.
  • the step of shrinking by spinning can be carried out by displacement of the front half-jaws 11, 12 or alternatively by displacement of both the front half-jaws 11, 12 and rear half-jaws 21, 22.
