Definitions

  • the invention relates to a magnetic coil and a method for their manufacture.
  • the invention is therefore based on the object, the magnetic coil and the process for their manufacture in To improve in terms of a lower failure rate while simplifying manufacturing.
  • connection between the connecting tongue and the contact pin not just a relative shift in the longitudinal direction of the Contact pin, but also in addition to this Direction. This creates an additional degree of freedom provided an even more flexible connection between the tongue and the contact pin or coil body guaranteed.
  • the coil wire which is usually is covered with an insulating varnish layer Dip soldering contacted with the contact pins.
  • an insulating varnish layer Dip soldering contacted with the contact pins.
  • the insulating varnish dissolves and an electrical connection through the solder between contact pin and coil wire results.
  • the magnetic coil shown in Fig.1 consists essentially from a bobbin 1 with wound Coil wire 2, a magnetic core 3 and an armature 4.
  • contact pins 5, 6 are provided to the one end of the coil wire 2 is wound in each case. These contact pins 5, 6 are at one end in the bobbin 1 and are at their other ends coupled with a tongue 7, 8.
  • the two connecting tongues 7, 8 are on a tongue carrier 9 arranged on a magnetic yoke 10 the solenoid is held.
  • the connecting tongues 7, 8 have for coupling with the Contact pins 5, 6 clamping means on the one hand electrical connection and on the other hand a displaceability the connecting tabs opposite the contact pins ensure in the longitudinal direction.
  • these clamping means also allow additional relative displaceability of the connecting tongues compared to the Contact pins transverse to the longitudinal direction of the contact pins.
  • clamping means are in the illustrated embodiment as slots 11, 12 in the connecting tongues 7, 8 formed, the contact pins 5, 6 between the the flanks 11a, 11b delimiting the slot 11, 12 or 12a, 12b are held.
  • the two flanks 11a, 11b and 12a, 12b are slightly bent, whereby the resulting slot width is slightly less than that Width of the contact pins, preferably square in cross section.
  • connection carrier 9 shown arranged, this connection carrier 9 has two snap hooks 15, 16 which can be coupled to the magnetic yoke 10. Doing so at the same time an electrical contact between one Ground terminal tongue 17 and the magnet yoke 10 are produced. While the individual connection tabs made of electrical conductive material, in particular metal, the connection carrier 9 is made of non-conductive material, preferably made of plastic.
  • connection tongues 7, 8 are not arranged on a connection carrier are.
  • connection tongues 7, 8 plugged onto the contact pins 5, 6.
  • connection tongues are held on the connection carrier, so that the attachment process for both connecting tongues takes place simultaneously.
  • the bracket of the connection carrier is ensured via the snap hooks 15, 16.
  • the solenoid is in a suitable shape encased in plastic.
  • connection of coil wire 2 and contact pins 5, 6 on the one hand and the clamping means of the connecting tongues represent the manufacturing process simplify itself per se. So in particular when contacting the connecting tongues on one Welding process can be dispensed with. So they can be Solenoids according to the invention not only with less Effort but also with a lower reject rate produce.
  • Magnetic coils of this type are used, for example, in connection used with solenoid valve coils with which Valves can be controlled by fluid lines.
