Definitions

  • the invention relates to a multi-pole interference suppression choke according to the introductory part of patent claim 1.
  • interference suppression of multiple lines has so far been achieved by means of lead-in capacitors which are easier to manufacture but much less effective in terms of inductances, and which also have an inductive component by coating the inner conductor with magnetically conductive material , accomplished, whereby such an element was required for each of the often very many lines of data lines.
  • the assembly of the many individual interference suppression elements was again complex and therefore expensive.
  • the frame core or multi-hole core can be snapped into it in a particularly simple manner by machine using the snap connection provided on the holder.
  • Its special shape allows the use of automatic machines for winding the core snapped into the holder with the large number of windings, fixing the winding ends to the connecting pins carried by the holder and the subsequent connection Solder the winding ends to the connector pins.
  • subclaims relate to preferred embodiments of the interference suppressor according to claim 1.
  • Subclaims 2 and 3 relate to preferred designs of the core with regard to the fully automatic winding, and claims 4 and 5 relate to preferred measures in connection with the possibility of using placement machines in the Manufacture of the components to be equipped with a suppression choke according to the invention.
  • a frame core 1 and below it a multi-hole core 2 is shown, both of which have a substantially rectangular, elongated outer contour.
  • the frame core 1 has a substantially constant thickness around the single hole 1a, so that the single hole 1a has a cross section similar to the outer contour of the frame core 1.
  • the plurality of holes 2a have a substantially rectangular cross section and they lie in a row parallel to each other.
  • the elongated core which is a frame core 1 here, but could also be a multi-hole core 2 is received by a holder 3, into which it can be snapped onto the holder 3 by means of resilient snap hooks 3a.
  • the holder carries in a row parallel connection pins 4, which are angled at right angles to form fastening ends 4a for the winding ends and perpendicularly projecting from the bottom surface of the holder 3 contact pins 4b.
  • a plurality of windings 5 are wound side by side, the ends of which are fixed to the fastening ends 4a of the connecting pins 4.
  • the flat shape of the core part, on which the windings 5 are located, and the substantially rectangular shape of the individual opening 1a, through which they extend, enable the use of automatic winding machines to apply the windings without further ado.
  • the winding ends of the unit consisting of the holder 3 and the frame core 1 can also be fixed fully automatically to the connecting pins 4 and then soldered fully automatically.
  • the winding of the frame core 1 takes place in the assembled state with the holder 3.
  • the above also applies in connection with the use of the multi-hole core 2 shown in Fig.1.
  • the core, which also extends on the upper, longitudinally extending flat section on wound individual turns is separated from one another by magnetic inferences, ie are completely decoupled from each other.
  • the multi-pole interference suppression choke according to Fig. 2 has a configuration according to the DIL standard, so that with its contact pins 4b lying in a row with automatic assembly machines can be handled during assembly on the components to be equipped with it. For this purpose, it is preferably introduced into a housing (not shown in the drawing).
