Definitions

  • the invention relates to strip ends for electrical conductors, the method for manufacturing these ends and their application to the mass production of conductive wires fitted with ends or terminals produced according to the method.
  • Patent FR 2 468 224 discloses a method of manufacturing band end caps, but this process seems difficult to automate, because it is necessary to introduce the tubes of the end sleeves on cores in order to be able to overmold the insulating sheath and the strip portions connecting several end caps.
  • the object of the invention is to avoid these drawbacks and to allow automated manufacture of strip end caps, and its application to the mass production of conductive wires fitted with end caps or terminals.
  • Another object of the invention is to allow the manufacture of end pieces from a metal strip, which reduces the manufacturing cost, while providing end pieces which can be supplied in strip form.
  • a final object of the invention is to obtain band ends using the least number of parts possible and to provide a manufacturing process using the lowest possible number of steps and rework of parts.
  • a ferrule for multi-stranded conductor cable intended for crimping multi-stranded conductors, is characterized in that it comprises a shape cut from a metal strip having a rectangular body shaped as a trough, a head overmolded in plastic material and shaped at least in a chute, and a collar connecting the body to the head.
  • FIG. 1 represents a first embodiment of the end piece and the different stages of the manufacturing process.
  • the end piece is obtained from an electrically conductive metal strip cut according to the shape shown in step A of the process.
  • This form 1 comprises a main body 10 of rectangular shape, a head 11 comprising dovetail cutouts 12; this head is connected to the body 10 by a neck 13.
  • the entire cutout constituting the end piece is connected to the edge of the metal strip 14 by an appendage 15.
  • the strip driven by the holes 19 will pass through stations successive work where she will undergo operations B, C, D, E, F, G.
  • the head 11 and the body 10 are given a form of trough by stamping. This constitutes the second phase B of the process.
  • the head 11 is given the shape of a split crown or ring shown in step C.
  • step D the strip end pieces are introduced into a plastic molding machine which overmoulds the head 11 with an insulating plastic material 16. Continuous strip end pieces are thus obtained, the appendages 15 of which can be possibly cut if you want to deliver the tips in bulk.
  • a final step E is added when it is desired to obtain multi-strand conductive cables 2 coated with an insulating sheath 20, these cables being fitted with end caps at their ends, as shown in FIG. 2.
  • This last phase includes step E shown in Figure 3, on which we can see a strip of tips overmolded at the insertion station for multi-strand conductor cables 2.
  • the conductive cables 2 previously cut to standardized lengths and stripped at their ends, are introduced axially into the overmolded cylindrical head, until the sheath 20 abuts against the bosses 161 shown in FIG. 4.
  • the multi-strand conductors 21 are then facing the conductive portion of the body 10, then are crimped in the end piece in step F.
  • step G which is optional, the conductors fitted with end caps are separated from the strip by cutting off appendix 15.
  • the dovetail teeth 12 are slightly flared at an angle of the order of 30 °, as shown in FIG. 4.
  • the conicity given to the teeth 12 makes it possible to obtain a good anchoring of the metal part of the nozzle in the overmolded plastic.
  • the overmolded part 16 comprises a conical portion 163 for guiding the multi-strands, as well as a cylindrical portion 164 provided with internal bosses 161 for immobilizing the insulating sheath of the conductive cable.
  • a tongue forming a hook 162 intended to receive index markers.
  • Such a tongue is well known to those skilled in the art and already described in Patent FR 1,468,859.
  • FIG. 5 represents a second embodiment of the end pieces and the different stages of the method.
  • the strip is brought to a station where the piece 1 undergoes a stamping operation, so as to give said piece the shape of a chute, as shown in step B.
  • each part or set of parts is subjected to an overmolding operation C, with plastic material, of all or part of the head 11.
  • a conductive cable 2, stripped on a portion 21, falls vertically into the trough of each piece 1, so that the insulating part 20 of the cable coincides with the overmolded portion 16 and that the stripped portion 18 is opposite the conductive portion 10 of the nozzle.
  • This operation is followed by the crimping operation of one or more end caps, shown in step E.
  • the metal part 10 is crimped onto the multi-strand conductor 21, while the overmolded part tightens the sheath insulating 20.
  • This operation G can be followed by an operation G, not shown, of cutting the appendix 15.
  • FIG. 6 a distinction is made between the axial offset between the portion 11 and the portion 10, which is necessary so that the axis of the conductive strands merges with that of the insulating sheath 20.
  • This offset is obtained during the stamping operation B, by deformation of the neck 13 connecting the body 10 to the head 11.
  • the overmolded plastic material 16 is anchored on the head by the holes 12.
  • a tab 162 serving as an index holder.
  • FIG. 7a represents a variant of a nozzle obtained according to the first embodiment with, in place of the tongue 162, a rectangular opening 165 allowing the fixing of a label-carrying tongue not shown and of the type mentioned above .
  • Figures 8, 9, 10, 11 show different applications of the ends obtained according to the second embodiment for obtaining end caps.
  • the tips in which there are the various constituent parts; 16 the overmolded part; 10 the crimpable part and 13 the junction neck (not shown) between the two parts 16 and 10, are extended by a second junction neck 30 of the crimpable part to a portion 31, 32, 33 or 34 constituting a connection terminal .
  • This portion of junction terminal can have, as shown in Figures 8, 9, 10, 11, any shape allowing to achieve all types of fixing and connection that is desired.
  • the lugs 31 and 32 allow a connection by screws, while the lugs 33 and 34 of the type known in the Anglo-Saxon literature under the name of "fast-on” allow a connection by tightening.
  • the shapes of the lugs 31, 32, 33, 34 are obtained, during the manufacturing process, by cutting and bending the metal strip and are connected to the strip by the tongues 15.
  • the same process for manufacturing the ends assembled in series on conductor cables of standard length applies to terminal lugs. It is therefore sufficient to provide, in the manufacturing operations, for the cutting operations of the second neck 30 and of the second body 31, 32, 33, 34 as well as the lug-shaped forming operations.
  • the overmolded parts can also be provided with label holder means.
  • the overmolded part instead of obtaining an overmolded element in the form of a chute, the overmolded part will be cylindrical as in step D of FIG. 1.
  • the other parts 31 to 34 will be identical and connected by a neck 30 to the part crimpable.
