Definitions

  • the invention relates to a method for producing a permanent connection between an electrical connector and a multi-wire conductor according to the preamble of claim 1 or 2 and is based on US-A-2 451 800.
  • solder is placed on the superimposed ends of the conductors before crimping an annular or spiral crimp sleeve, either by coating the inside of the sleeve with solder or by introducing the solder together with the conductors, e.g. B. by coating the conductor ends with it.
  • the soldering heat is applied to the contact section by the crimping stamp.
  • the aforementioned type of plug connector is used in the wiring of electrical and electronic devices and systems, in particular also in household appliances and automobiles.
  • the invention has for its object to provide a method for producing a connection between an electrical connector and a multi-wire conductor, in which the advantages of soldering and crimping are advantageously connected.
  • the invention proposes a method according to one of claims 1 or 2.
  • the method according to the invention leads to connections with very low electrical contact resistances and high tensile strength.
  • the risk of corrosion is low.
  • the two process technologies, crimping and soldering can be combined well in terms of the device. In particular, good portioning of the solder mass is possible. This also prevents solder from migrating to the plug section of the connector and impairing the proper plug connection.
  • the connector 1 is stamped and bent in the exemplary embodiment as a socket 2 with a crimp claw 3 from sheet metal.
  • the Krimmp claw 3 is used to connect to a stripped end section 4 of a stranded conductor 6 provided with insulation 5.
  • the crimp claw 3 has two pairs of tabs 7 and 8, between each of which a space 9 and 10 is provided.
  • the longitudinal axis of the crimp claw 3 coincides here with the longitudinal axis of the socket 2, it is denoted by x-x. That this does not always have to be the case is described, for example, in FIGS. 4 to 6.
  • the spaces 9 and 10 extend approximately at right angles to the longitudinal axis x-x; another arrangement, for example at an angle of 45 °, is also possible.
  • a piece of solder wire 11 is clamped into the spaces 9 and 10.
  • the crimp claw 3 is placed between two electrodes 12 and 13.
  • the lower bridge part 3a of the crimping claw 3 lies on the electrode 12, while the electrode 13 presses directly between the flap pairs 7 and 8 in the region of the spaces 9 and 10 onto the section 4 of the stranded conductor 6.
  • the solder wire 4 melts.
  • a kind of capillary effect can be seen: The ends of the piece of solder wire 11 are "sucked" into the strand section 4 and fill the spaces between the strands there 6 out. The result is a homogeneous connection between the strand 6 and the crimp claw 3.
  • FIG 3 the same connector 1 is shown as in Figure 1.
  • the crimping claw 3 was first struck on a strand 6 'without solder wire. From above, an end section of a solder wire 11 'is brought vertically towards section 4' of the strand 6 ', which is exposed in the spaces 9 and 10 between the pairs of flaps 7 and 8 without being insulated.
  • a coil 14 is arranged above the crimping claw 3, which inductively heats the solder wire 11 ', so that the solder drops in the form of drops through the spaces 9 and 10 onto the section 4' of the strand 6 '.
  • the solder penetrates into the strand 6 'and fills in all the spaces in between. The result is a homogeneous connection between the strand 6 'and the crimp claw 3rd
  • FIGS. 4 to 6 show a plug connector 21 with a socket 22, in which the longitudinal axis x'-x 'of the crimping claw 23 extends perpendicular to the axis x "-x" of the socket 22; in another application, it could also run at an angle of, for example, 45 or 60 ° to it.
  • the crimping claw 23 is intended for attachment to an end section 24 of an insulated wire.
  • a pair of lobes 25 is arranged on the crimp claw 23, which extends almost perpendicular to the x-x and x'-x 'axes.
  • the crimping claw 23 is bent slightly at the ends 26 of the pair of tabs 25 in the direction of the socket 22 for better rolling.
  • a piece of solder wire 28 is clamped in the intermediate space 27 between the pair of tabs 25.
  • a stripped end section 24 (or intermediate section) of a stranded conductor is now introduced into the crimping claw 23 and struck on the plug connector 21 together with the piece of soldering wire 28 by rolling in the tabs 25.
  • the result can be seen in FIG. 5.
  • One end of the solder wire 28 protrudes from the space 27 of the crimping claw 23.
  • the solder joint is now heated, and the solder wire 28 pulls into the strand 24.
  • the result is a homogeneous connection between the strand 24 and the crimping claw 23.
  • the opening can not only as an open slot, but z. B. also be designed as an elongated hole, the z. B. is arranged in the bridge part 3a of the crimp claw 3. In this case, the opening has only been moved to the other side of the crimping claw 3.
