Definitions

  • the invention relates to a method for tearing-proof contacting enameled wires on contact elements. More particularly, the invention relates to the application of this method in electronic components such as RF choke with wire-wound ceramic, plastics or ferrite k emen.
  • RF choke with wire-wound ceramic, plastics or ferrite k emen.
  • Such chokes can be provided with connecting wires or can also be designed as so-called choke chips with connecting lugs.
  • the induction coils used are becoming smaller and smaller as part of a progressive miniaturization.
  • the winding wires used have an ever smaller diameter, which makes contacting the coil connections more difficult.
  • the enamel-insulated coil connections can have a diameter in the range from 30 to 100 ⁇ m (0.03-0.1 mm).
  • P 34 33 692.3 such a miniaturized RF choke in chip design is proposed, in which single-layer or multi-layer wound, lacquer-insulated wire must be contacted on plate-shaped contact elements.
  • lacquer-insulated coil connections have been contacted by manual, mechanized or even fully automated soldering. Temperatures of approx. 500 ° C are necessary especially for soldering such high temperature resistant enamelled wires. The heat radiation can damage the materials in the immediate soldering area.
  • Ultrasonic welding can advantageously be used for contacting, the lacquer insulation layer being equally broken up and the welding effect being achieved due to the mechanical effect of the ultrasound.
  • problems arise with diameters of enamel-insulated wires below 0.4 mm, since when welding the wire is weakened by the deformation at the connection point. Since the mechanical requirements can generally not be maintained, an additional cover plate has to be welded on to improve the mechanical strength. The latter is described specifically for laser welding in DE-OS 33 07 773. In the manufacture of HF choke coils, which are either manufactured with connecting wire or more recently with connecting lugs as so-called HF choke chips, this would mean an additional effort, since the cover plates have to be fed in before welding.
  • the object of the invention is therefore to provide an improved method for contacting thin enamel-insulated wires on a metallic base. This method should be applicable in particular for choke coils in chip design.
  • the object is achieved in that the wire is deformed by the action of ultrasound while breaking the insulating layer and welded onto the contact element and that the entire deformation area is then coated with a drop of an organic or inorganic adhesive.
  • the method according to the invention can be easily integrated into a production line, and the welding and subsequent gluing can take place automatically.
  • a thixotropic adhesive substance which can be hardened quickly is preferably used as the adhesive.
  • HF choke coils with wire-wound ceramic, plastic or ferrite cores which are designed as so-called choke chips and have large-area connection lugs as contact elements
  • the insulated winding wire is placed around the terminal lug of the choke chip at each end, the wire end is welded to the terminal lug and the welding point is covered with organic or inorganic adhesive.
  • the insulated coil wire can be wound around the end of the connecting wire, the coil wire being welded to the connecting wire in the immediate vicinity of the core end and the entire stimulating area of the core end running around the wires with an organic or inorganic Adhesive is covered.
  • the advantages of ultrasound welding of enamelled wires such as reliable contacting and the low temperature load, are used and, likewise, the previous disadvantage of low strength is compensated for by the application of the adhesive.
  • Such adhesives are easy to handle and can be applied as drops to the weld. After curing, the adhesive is mechanically strong and in particular also resistant to temperature changes. The volume of the adhesive drop can be chosen so that the entire deformation point is enclosed. The result of this is that the strength of the contact is greater than the wire strength.
  • 1 means a metallic base, for example a contact element, on which a paint-insulated wire 2 is to be contacted.
  • Ultrasound welding can advantageously be used for this purpose, for which an ultrasound sonotrode with 10 and associated ultrasound anvil with 11 are indicated.
  • the insulation layers are broken up by the mechanical effect and the metallic parts are contacted by friction welding with simultaneous deformation.
  • a one-component adhesive is used as the adhesive. It is important for the intended use that the adhesive substance is thixotropic, i.e. dimensionally stable, is and hardens quickly. In automated production, a drop of the adhesive can then be applied to the welding point directly after welding, which hardens after passing through UV light after a few seconds, so that there is a shape 4 which encloses the deformed area of the wire 1.
  • an RF choke is designated 20.
  • Such chokes usually consist of a core 21, which can be made of ceramic, plastic or ferrite, with a single-layer or multi-layer winding 24 made of enamel-insulated round wire.
  • a core 21 which can be made of ceramic, plastic or ferrite, with a single-layer or multi-layer winding 24 made of enamel-insulated round wire.
  • the core 21 has end faces 22 with cutouts 23, into which connection tabs 25 with a platelet surface are introduced on the front and rear sides.
  • the connecting lugs 25 are bent at their free part so that they can be plugged onto printed circuit boards or the like.
  • connection lug 25 must be contacted with the winding wire 24:
  • the winding wire 24 is placed diagonally around the connection lug 25 and the end 26 of the winding wire 24 is welded on using ultrasound in the manner described above.
  • a drop of the specified adhesive is then applied to the surface of the connecting lug 25.
  • An approximately wart-shaped area 27 is formed, which covers the entire deformation area of the ultrasonic welding. After the adhesive has hardened, a mechanically stable connection is achieved.
  • an HF choke 30 has a ceramic, plastic or ferrite core 31, on which a wire winding 34 is located. On the end face 32 of the core end, a connecting wire 35 is led out, which can be anchored in the core 31.
  • the connecting wire 35 is to be contacted with the winding wire 34.
  • the end 36 of the winding wire 34 is wound at the end around the connecting wire 35 and thus welded in the immediate vicinity of the core 31 by ultrasound.
  • the entire area of the end face 37 of the core 31 surrounding the two wires 35 and 36 is covered with an organic or inorganic adhesive.
  • a grommet shape 37 can form during curing.
