Definitions

  • the invention relates to a coil former made of insulating material with openings provided in a flange part for the pluggable fastening of metallic connection elements for winding ends.
  • Coils for relays or other switching devices are usually wound with automatic machines and then inserted as a whole into the corresponding device.
  • connection pins are already fixed in the coil former by injecting or plugging in before winding, the winding ends can be wound directly from the winding machine onto the connection pins and soldered to them in a subsequent operation.
  • the S p u for the mechanized initial winding - in each case an auxiliary base lenenden required, which can be either integrally formed or on the insulating material of the coil body anchored in the form of a wire therein.
  • the object of the invention is to provide a bobbin so that the winding ends me in a simple manner chanized wound on auxiliary bases and can then be connected by simply soldering to subsequently inserted metal connection elements.
  • this object is achieved on a bobbin of the type mentioned at the outset in that retaining pins are formed on at least two opposite edge regions of the openings, which are each at least as wide as the part of a connecting element which can be inserted between them through the opening.
  • two holding pins forming a breakthrough for a connecting element, together forming a winding base, on which one end of the winding can be wound such that a connecting element is added between the holding pins.
  • a connecting element is added between the holding pins.
  • the connecting element is twisted with its free end between the two holding pins. In this case, the width of the retaining pins should correspond to the twisted and thus transverse end of the connecting element.
  • the connecting element can also be fixed to the coil body by a bent tab.
  • the coil body 1 shown in FIGS. 1 and 2 has a coil tube 2 for receiving a winding and two flanges 3 and 4.
  • An extension 5 is formed on the coil flange 4, which has openings 6 for receiving sheet metal connecting elements, not shown here.
  • Holding pins 7 are formed on both sides of each opening 6, each of which is wider than the opening 6, so that a winding end wound over both holding pins 7 does not hinder the insertion of a connecting element.
  • the holding pins each have a shoulder 8, so that the winding end wound on the free end 7a cannot slide down and thus remains easily accessible for soldering.
  • FIGS. 1 and 2 show a perspective view of a detail from the coil former shown in FIGS. 1 and 2.
  • the holding pins 7 arranged on the extension 5 of the coil former already carry a wound winding end 9 which is wound with several turns around the offset ends 7a of the holding pins 7.
  • connection element 10 After winding the coil, a connection element 10 is inserted into the opening 6, so that its free end 10a lies between the holding pins 7. This free end 10a is twisted to fix the connection element. Thereafter, the electrical connection between the winding end 9 and the connecting element 10 can be established in a simple manner by soldering.
  • FIG. 4 A somewhat modified embodiment compared to FIG. 3 is shown in FIG. 4.
  • the connecting element 10 is inserted and twisted in the same way as before.
  • FIG. 5 A further modification is shown in FIG. 5.
  • Two retaining pins 27 are each shaped so that they surround the connecting element 30 inserted between them in a U-shape. This connecting element 30 is then soldered to the winding end 9 in the slot 31 provided on both sides. A shoulder 28 also prevents the winding end from slipping down here.
  • this is provided in this embodiment with a side tab 32 which lies in a side slot 33 of a holding pin 27 and fixes the connecting element 30 on the coil body by lateral bending.
