Definitions

  • the invention relates to a soldering lug for fastening electrical lead and winding wires, and in particular to a soldering lug which is held in a coil body flange of an electrical coil.
  • solder tags are also known, in which the ends of the winding wires are pinched by mechanical deformation of the solder tag and are thereby fixed. All of these known designs require a considerable amount of time for fixing the winding wire ends, some additional, manually operable aids which are difficult to automate being necessary.
  • the known flake-shaped soldering lug 1 partially broken and shown in plan view in FIG. 1, has a notch-like edge-open recess 2, into which the end of the winding wire can be clamped.
  • the disadvantage of this solder tail is its rigid design, which must be matched to the wire diameter. Different wire sizes therefore require a different solder lug design. In addition, there is always the risk that the wires will be cut through by a sharp-edged notch when fixing.
  • the present invention has for its object to provide a solder tail that offers the possibility in a simple, non-destructive and quick way to fix differently strong electrical lead wires, in particular winding wires, securely in position until the completion of the soldering process; in particular, this soldering tag should be suitable for use in electrical coils, which are wound automatically.
  • the invention provides for a solder tail of the type mentioned, that these free at least in its serving for fixing the electric wires or the winding wire ends end of layered V-shaped spread leaf springs or from a blättchenförmi g s material with resilient Properties is formed.
  • the wire With this soldering lug, the wire can be fixed quickly and securely even with different wire thicknesses. Only by pulling the wire between the spread ends of the leaf springs is it sufficient to hold the wire sufficiently for the subsequent soldering process. An additional wrapping around the Solder tail with the wire, which was previously common and very expensive, can be omitted. By pulling the usually electrically insulated winding wire ends into the solder lug, the lacquer insulation is torn open at the point to be soldered, thereby enabling safe and quick soldering.
  • This type of holder ensures a significantly higher economy compared to the previously used fixing and soldering processes.
  • This soldering lug creates considerable advantages, in particular in the case of automatic winding of coil formers, since the automatic winding machines can pull the winding wire ends directly into the soldering lug and fix them.
  • the solder tail can consist of two layered leaf springs, the mutually adjacent one ends of the leaf springs being spread out in a V-shape. It is conceivable both the mechanical connection of the leaf springs, for example, which is folded about its vertical center axis to the leaf spring 180 to 0 by spot welding at their one ends, as well as a solder tail, which consists of a single leaf spring.
  • soldering lug is fastened in the coil body flange with its end facing away from the V-shaped end, e.g. poured into this or clamped in corresponding slots.
  • solder tab facing away from the V-shaped spread as an electrical connecting pin e.g. designed for printed circuits and the soldering lug with its central part is held securely in a slot-like opening in the coil body flange.
  • the pair of leaf springs can be made in one piece from a T-shaped element made of spring sheet metal folded about its longitudinal central axis by 180 °.
  • a soldering lug is also conceivable which, as already mentioned above, consists of two layered leaf springs which are connected to one another along one leg 8, for example by spot welding, as shown in FIG. 4 shows. The same parts are again provided with the same reference numerals.
  • FIGS. 5 and 6 are particularly suitable for use in coil former flanges, as shown in FIGS. 5 and 6.
  • FIG 5 shows a coil fastened to a printed circuit board 34, wound with a winding 33, with a coil former 31 with coil former flanges 32 with its longitudinal center axis parallel to the printed circuit board.
  • the coil former flanges 32 as can be seen in FIG on, in which the solder tails 6 are inserted.
  • the soldering lugs 6 carry integrally molded parts for their fixation in the rectangular openings 41.
  • Lugs 10 for additional fixation of the solder lugs in the openings, these can be equipped with embossments 13, 15 or 12, 16. With its pin-shaped part 8, the solder tail is guided through an opening in the circuit board and e.g. soldered to a conductor track 35.
  • the leaf spring ends 7, 14 are optionally hook-shaped - as indicated at 9 - and thus allow the possibility of an additional fixation.
  • FIGS. 7, 8 shows a leaf spring folded about its center by 180 °, the legs 51, 52 of which are additionally curved in an L-shape and are provided with hook-shaped recesses 53, 54 for additional fixing of wires.
  • This version is suitable, for example, for use in sack-like recesses in the coil body flange.
