Definitions

  • the invention is based on an operating device according to the preamble of the claim 1. It is in particular an operating device for the operation of Fluorescent lamps, the particularly inexpensive winding goods with small dimensions contains.
  • Inexpensive winding goods contain a core in a simple geometric Shape. If the winding material is to have small dimensions, it is advantageous to when the core largely encloses the winding. This also prevents the Propagation of interference fields. However, such winding goods require expensive Geometric core shapes that can only be produced at great expense can.
  • the object of the present invention is an operating device according to the preamble of claim 1 to provide, the winding goods at the same time small dimensions have and are inexpensive.
  • a winding material is generally made up of several parts. In addition to the winding with their wire ends, there are essentially two types of parts.
  • a kind of of parts is mainly magnetic; d. H. it consists of a ferromagnetic Material and serves to guide the magnetic field.
  • the other Parts are mainly mechanically effective. This type of parts is used e.g. B. for receiving the winding or as a holder for the magnetically active Parts.
  • An important task of mechanically effective parts is the fixation the wire ends of the winding. The electrical contact is made by the fixation of the winding material.
  • a winding material contains parts that both act magnetically as well as mechanically. This will reduce the number of parts and thus reduce costs.
  • the wire ends are fixed by a part that is also magnetically effective.
  • Magnetically effective parts are usually made from a sintered ferrite. Therefore, it is difficult to manufacture such parts in a complex form. Should however, according to the invention, a magnetically effective part also has mechanical tasks complex forms are usually required. To solve this problem solve, parts that are both magnetically and mechanically effective are advantageous made of a composite material containing ferrite and polymers and thereby can be produced in an injection molding process.
  • the magnetically active parts of an inductance usually have one Structure that has an air gap.
  • the value of inductance becomes essential determined by the size of the air gap. Manufacturing tolerances that the air gap concern lead to tolerances in the value of the inductance.
  • the above composite material can be designed in its composition of ferrite and polymer that it acts like an air gap distributed over a whole part. According to the invention the entire air gap of an inductance is advantageously selected by a suitable choice Composition of the composite material formed. This allows smaller tolerances for the value of an inductor.
  • the material to be wound contains parts that are pushed into each other.
  • these are two parts made of said composite material which slide into one another form a cavity that houses the winding.
  • a part forms a pot for easy manufacture.
  • a roll on which the winding is applied.
  • a part can also form a role over which a tubular or pot-shaped Part is pushed. Again, the winding is applied to the roll.
  • a winding material which contains two parts 1 and 2, both are magnetically and mechanically effective. Both parts 1 and 2 are advantageous made of a composite material described above.
  • Part 1 forms one pot-shaped recess into which the part 2 is inserted.
  • Part 2 is essentially a roll of which in plan view only the upper disc-shaped end you can see.
  • An air gap 6 is formed between part 1 and part 2. This can be omitted if the material for parts 1 and 2 is so is chosen that it can take over the task of the air gap 6.
  • part 1 is a part that is made of one material throughout is manufactured and is both magnetically effective and an assembly platform forms.
  • FIG. 2 shows the exemplary embodiment from FIG. 1 in section. Same components are provided with the same numbers. The role of the part is clear 2 can be seen on which the winding 3 is applied. 2 is also clear like the wire ends 7 and 8 in a slot in the wall of the cup-shaped depression from part 1 come to rest.
  • part 1 can also be designed in this way be that a role is formed on an assembly platform on which the Winding is applied. A tubular or pot-shaped part is then over this roll pushed, whereby the winding is enclosed.
