Definitions

  • the invention relates to an inductive miniature component for SMD assembly with a coil carrier made of plastic or ferrite material, in or on the at least one coil winding is arranged, being on an outside of the Coil carrier and in one piece with this connecting pin projecting outwards are arranged around which one end of the winding wire each Coil winding is wound around in several turns, as well as a method for the production of such a component.
  • Such a miniature inductive component with a ferrite material existing coil former is, for example, in the German utility model No. 298 24 118.8.
  • the invention has for its object an inductive miniature component for SMD assembly with the introduction and in the preamble of claim 1 the specified features so that even when using Winding wires with a very thin diameter risk of tearing the end of the winding wire considerably even when subjected to shock vibration is reduced.
  • the basic idea of the invention is the respective end of the winding wire not to wind up directly on the connecting pin, but the To first connect the connecting pin with a wire in several turns
  • the diameter of the wire of the metallizing wire winding should be so large be that its tensile strength is sufficient, the demands made on the component with regard to impact and shaking loads. It turned out that it is convenient if the wire of the metallizing wire winding has a diameter that is at least twice as large as the diameter of the winding wire.
  • the wire of the metallizing wire winding can be a CuAg wire, it a tinned copper wire can also be used or a wire made of an alloy with higher tensile strength, such as bronze.
  • connection technology according to the invention is both in coil formers Plastic material as well as coil carriers made of ferrite material and ceramic plates applicable.
  • the arrangement of the connecting pins is arbitrary and can can be adapted to the respective needs.
  • a transponder coil is shown with a hood trained coil carrier 1, in which a coil winding 2 is inserted.
  • the Coil carrier 1 has an octagonal layout and is made of plastic material.
  • connection pins on every second side surface of the coil carrier 1 1.1, 1.2, 1.3 and 1.4 arranged, which are integrally connected to the coil carrier are.
  • the connecting pins 1.1 to 1.4 are in the transverse direction to the coil axis arranged.
  • the ends 2.1 to 2.4 of the coil winding 2 are each wrapped around the connecting pins 1.1 to 1.4 in several turns.
  • Fig. 4 shows details of this connection technology using the example of the connecting pin 1.1.
  • a metallizing wire winding 3.1 which consists of a there is electrically conductive wire whose diameter is larger than that Diameter of the winding wire 2.1 and directly in several turns is wound on the connecting pin 1.1.
  • FIGS. 5 to 7. It is here again around a bobbin 4 designed as a hood, which has a rectangular one Has floor plan and the connecting pins 4.1, 4.2, 4.3, 4.4, 4.5, 4.6 are each on two opposite side walls of the coil carrier 4 arranged.
  • FIG. 8 Another example is the coil carrier 5 shown in FIG. 8, which is a ceramic Plate is designed for a double-hole core transformer and to the opposite side surfaces of connecting pins 5.1, 5.2, 5.3 or 5.4 and 5.5.
  • the connection of the ends of the not shown Winding in the same way as described with reference to FIG. 4.
  • Fig. 9 shows another way of forming the coil carrier.
  • the Coil carrier 6 is designed here as a ferrite winding body with two connecting pins 6.1 and 6.2 on the opposite sides of the winding body.
