Definitions

  • the present invention relates to insulation displacement contacts for connection of insulated electrical conductors, without prior stripping of these conductors.
  • Such an insulation displacement contact is described in particular in document FR-A 2457 573. It has a simple or double insulation displacement fork and in the latter case of various possible combinations such as head to tail or side by side.
  • the simple insulation displacement fork contact is formed by a conductive part in which a slot defines the two elastic branches of the fork. It is furthermore with an insulated conductor entry into the slot, coupled to one end of said slot by at least one insulating sectioning stage and possibly open on one of the edges of the part, and with elasticity hole of the two branches located at the other end of said slot, on its bottom.
  • the double fork contact side by side can have one of the branches of its forks which is common to them.
  • the spacing of the two branches of each fork is obtained either by local crushing and the resulting displacement of material on one of the two branches, or by two crushing and the resulting displacements of material on one and the other of the two branches.
  • This crushing or the two crushings are carried out near the or two edges of the slot, between its bottom and the insulating sectioning stage, by a punch of circular section. They give rise to a rounded boss on the edge of the single branch concerned or of the two branches, calibrating the spacing of the two branches, in particular.
  • the spacing of the two branches is not symmetrical with respect to the fork axis. This arrangement is troublesome when the conductive wire to be connected is brought into the axis of the fork by means of positioning and connection, such as a pusher in particular. It leads to an increased integration effort.
  • the spacing of the two branches is theoretically symmetrical. However, it is not perfectly or sufficiently in practice.
  • the object of the present invention is in particular to avoid these drawbacks.
  • the insulation displacement contact constituted by a conductive strip comprising at least one slot, two elastic branches defined on said strip on either side of each slot, and an input of insulated conductor coupled to a first end of said slot by an insulating sectioning stage, characterized in that it further comprises a single punching of material delivery, substantially rectangular, carried out simultaneously on the only parts of said two elastic branches located on either side of substantially said first end of said slot, but not adjacent to said insulated conductor entry.
  • said punching defines two bosses with straight edges facing each other and in pressure contact on the axis of said slot.
  • the insulated conductor input initially produced by a substantially V-shaped cutout, has its bottom open by said punching to form said sectioning stage and define a short axial passage which tapers along said first end of the slot from this sectioning stage to said punching.
  • the insulation displacement contact is produced in a conductive strip 1, having a slot 2.
  • This slot 2 defines on either side of it on the strip the two elastic branches 3 and 4 of the insulation displacement fork. It opens at one of its ends into an inlet 5 of insulated conductor to be connected without prior stripping in the slot, this inlet 5 being in the example illustrated in FIG. 1 open on one of the small edges of the blade. It opens at its other end into a hole 6 of elasticity of the branches 3 and 4, this hole 6 being of oval shape and not open on any of the edges of the blade.
  • the inlet 5 and the elasticity hole 6 have their axis aligned with that of the slot 2.
  • the entry 5 is obtained by making a cut, in the form of a V with a base which can be truncated or not, in the end of the blade, with the opening of this V forming a slight constriction of retention of insulated conductor in this entry.
  • the slot 2 is on the other hand made without removing material, with its edges initially contiguous before its slight opening resulting from the separation of the two branches produced according to the invention.
  • This contact comprises a single punching of material discharge, forming a rectangular imprint 7 extending continuously on its two branches 3 and 4. This punching is carried out simultaneously on the two branches, but only on their parts located at the level of the part slot terminal which is close to the entry 5. This punching 7 is situated substantially at the end of the slot, but is however not entirely adjacent to the truncated base of the V of the entry 5.
  • this single rectangular punching 7 is only carried out on one of the faces of the blade, as shown in FIG. 2. It can of course, although not necessary, be carried out on both sides of the blade.
  • This punching 7 makes it possible to obtain, by crushing and displacement of material, a flattened boss 7A or 7B on each of the two branches, ensuring the spacing of the two branches on either side of the punching and their contacting under pressure over the width of the punching. It also makes it possible to obtain a reduced thickness of the blade at its level and in particular of the edges in contact with pressure of the bosses, which therefore participate in good penetration of the edges of the slot through the total thickness of the insulation of the driver.
  • the punch for carrying out the aforementioned punching 7 is illustrated on a substantially double scale in FIG. 3 and designated under the general reference 10. Its end 11 for mounting in a punch holder is of substantially square section. Its opposite end stamping part is of reduced section by the presence of two end chamfers 12 on two of its opposite side faces. The stamping end 13 is defined at the end of these two chamfers 12 by a terminal edge rounded between them.
