Definitions

  • the invention relates to a magnetic coil and a method for its production.
  • the electrical connection between the contact pins and the coil wire which is usually insulated with lacquer, is produced by suitable mechanical or electrical energy application.
  • the contact pin and the coil wire are excited by coupling vibrations in the ultrasound range, contacting being produced by the friction between the coil wire held under pretension and individual regions of the contact pins that come into contact with the wound coil wire.
  • the connecting tongues are usually welded to the contact pins.
  • the resulting relatively rigid connection leads to a relatively high failure rate in the mass production of such magnetic coils by tearing off the usually very thin coil wire, which may be only 0.04 mm thick. This demolition is caused by the inevitable Relative movements of the connecting tongues to the coil body when inserting and processing in the plastic coating form.
  • the invention is therefore based on the object of improving the magnet coil and the method for its production with a view to a lower failure rate and thereby simplifying the production.
  • connection between the connecting tongue and the contact pin not only permits a relative displacement in the longitudinal direction of the contact pin, but also additionally transversely to this direction. This provides an additional degree of freedom, which ensures an even more flexible connection between the connecting tongue and the contact pin or coil body.
  • the coil wire which is usually coated with an insulating lacquer layer, is contacted with the contact pins by dip soldering.
  • the area of the contact pins, which is wrapped with the coil wire is immersed in a solder bath, the temperature of which is so high that the insulating lacquer dissolves and an electrical connection between the contact pin and the coil wire results from the solder.
  • the magnetic coil shown in FIG. 1 essentially consists of a coil body 1 with a wound coil wire 2, a magnetic core 3 and an armature 4.
  • two contact pins 5, 6 are provided, around each of which one end of the coil wire 2 is wound. These contact pins 5, 6 are inserted at one end into the coil body 1 and are each coupled at their other end to a connecting tongue 7, 8.
  • the two connecting tongues 7, 8 are arranged on a tongue carrier 9 which is held on a magnet yoke 10 of the magnet coil.
  • the connecting tongues 7, 8 have clamping means for coupling to the contact pins 5, 6, which on the one hand ensure an electrical connection and on the other hand a displaceability of the connecting tongues relative to the contact pins in the longitudinal direction thereof.
  • these clamping means also allow the connecting tongues to be displaced relative to the contact pins transversely to the longitudinal direction of the contact pins.
  • these clamping means are designed as slots 11, 12 in the connecting tongues 7, 8, the contact pins 5, 6 being held between the flanks 11a, 11b and 12a, 12b delimiting the slot 11, 12.
  • the two flanks 11a, 11b and 12a, 12b are slightly bent, the resulting slot width being slightly smaller than the width of the contact pins, which are preferably square in cross section.
  • the two flanks of a slot have a resilient effect, so that a secure electrical connection is ensured when plugged onto a contact pin. Even after plugging in, the connecting tongues can be moved in the longitudinal direction of the contact pins (double arrow 13).
  • this type of coupling also enables a relative mobility transversely to the longitudinal direction of the contact pins, as is indicated by the double arrow 14.
  • the contact pins are displaced in the direction of the slots 11, 12.
  • connection carrier 9 shown in FIG. 5, this connection carrier 9 having two snap hooks 15, 16 which can be coupled to the magnetic yoke 10. At the same time, an electrical contact is made between a grounding tongue 17 and the magnetic yoke 10. While the individual connecting tongues consist of electrically conductive material, in particular metal, the connection carrier 9 is made of non-conductive material, preferably plastic.
  • FIG. 6 shows a second exemplary embodiment according to the invention, which differs from the previously described variant only in that the connecting tongues 7, 8 are not arranged on a connecting carrier.
  • the two ends of the coil wire 2 are automatically wound onto one of the two contact pins 5, 6.
  • the contact pins are then pressed deeper into the coil body 1 in order to relieve the wound coil wire.
  • the connecting tongues 7, 8 are plugged onto the contact pins 5, 6.
  • the connecting tongues are held on the connecting carrier, so that the push-on operation for both connecting tongues takes place simultaneously.
  • the holder of the connection carrier is ensured via the snap hooks 15, 16.
  • the magnetic coil is encased in a suitable form with plastic.
  • the type of connection of coil wire 2 and contact pins 5, 6, on the one hand, and the clamping means of the connecting tongues represent means which considerably simplify the manufacturing process itself. A welding process can thus be dispensed with, in particular when contacting the connecting tongues.
  • the magnetic coils according to the invention can be produced not only with less effort but also with a lower reject rate.
  • Solenoid coils of this type are used, for example, in connection with solenoid valve coils with which valves of fluid lines can be controlled.
