Definitions

  • the invention relates to an electrical connector with a contact section which is connected to a section of a multi-wire conductor, and to a method for connecting this connector and a device for carrying out the method.
  • Such connectors are 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 connector in which the advantages of soldering and of attachment are connected to each other.
  • the invention proposes that the contact section is divided into at least one pair of tabs that surround the conductor, that at least one opening is arranged between the tabs bent around the conductor as an access to the conductor, and that the tabs are soldered to the conductor.
  • the opening can extend transversely to the longitudinal axis or in the direction of the longitudinal axis of the connector.
  • One method of making an electrical connection with an electrical connector is to clamp a piece of solder wire between the tabs, to bend the pair or tabs around the conductor, and to heat the connector and / or conductor in the space .
  • the heating is carried out by electrodes resting on the contact section and / or the conductor.
  • Another method of making an electrical connection with a connector according to the invention provides that the pair or tabs are bent around the conductor and that liquid solder heated through the space is dripped onto the conductor.
  • a device for performing the aforementioned method provides that an electrical coil is used to receive and heat a solder wire.
  • connections according to the invention show very small electrical contact resistances and are highly resilient under tension.
  • the risk of corrosion is low, and the two process technologies crimping and soldering can be combined well in terms of device. In particular, it is avoided that solder migrates to the socket or the like and impairs the correct 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 crimping claw 3 is used to connect to a stripped end section 4 of a stranded conductor 6 provided with insulation 5.
  • the crimping 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 electrical resistance heating of the area between the electrodes 12 and 13 melts the solder wire 4.
  • 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 6 there. 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 in the direction of the section 4' of the strand 6 ', which is exposed in the spaces 9 and 10 between the pairs of tabs 7 and 8 without insulation.
  • a coil 14 is arranged above the crimping claw 3, which inductively heats the solder wire 11 ', so that the solder falls 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 3.
  • 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 n 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 tabs 25 is arranged on the crimp claw 23, which extends almost perpendicular to the axis xx and the axis x'-x '.
  • the crimping claw 23 is bent slightly at the ends 26 of the pair of flaps 25 in the direction of the socket 22 for better rolling. Between the pair of rags 25, a piece of solder wire 28 is clamped in the intermediate space 27.
  • 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 be an open slot, but e.g. also be designed as an elongated hole, e.g. the crimp claw 3 is arranged in the bridge part 3a. In this case, the space has only been moved to the other side of the crimp claw 3.
