Definitions

  • the invention relates to a choke or a transformer, in particular for use in ballasts for gas discharge lamps, as described in the preamble of claim 1 or 9.
  • the insulating molded parts which are pushed onto the winding heads of the winding in the form of an insulated coil are designed as one-piece insulating material housings which bear against the laminated core and which have a lower opening with the respectively adjacent end wall of the laminated core limit that is covered by a mounting rail connected to the laminated core.
  • These insulating material housings result in a significant simplification of the insulation of the winding because, after winding the coil, they are simply plugged onto the coil insulated in the area of their legs by means of a film sheathing, the wire ends of the coil being connected to connection devices provided on the insulating material housings before the whole is placed on the core.
  • the object of the invention is therefore to provide a choke or a transformer of the type mentioned, in which or in the case of a winding consisting of several coils, a perfect insulation of the winding heads of the individual coils from each other is ensured, without this in the context of Mass production would increase the manufacturing time of the choke or the transformer, while at the same time a perfect insulation of the winding overhangs is also guaranteed to the outside.
  • the choke or the transformer is characterized according to the invention by the features of claim 1 or claim 9.
  • the dividing wall of the Isolottottottormmaschine ensures that when the Isolierstoff-molded parts are plugged in a perfect insulation of the winding heads of the individual coils is produced against each other. No separate inserts in the form of press strip or the like need be inserted between the winding overhangs, which would have to take place in the course of additional operations which would increase the production time.
  • the tongue and the outer wall of the molded insulating material parts ensure perfect insulation both against the core of the laminated core and also towards the outside, with gaps remaining between the outer wall and the laminated core through the mounting rail or other parts already connected to the laminated core, for example a sheet metal jacket, can be covered.
  • the partition is arranged in the region between the tongue and the outer wall running approximately parallel to the tongue, the two coils assigned to it being inserted one into the other. This results in a very space-saving arrangement of the coils which is also advantageous in terms of production and insulation technology.
  • the partition may be expedient for the partition to have an approximately U-shaped cross section such that it surrounds the winding head of the internal coil with two laterally attached legs. Otherwise, the side walls of the insulating part can be supported against the adjacent end wall of the laminated core.
  • the insulating molded part is provided with a dividing wall which is profiled in a U-shaped cross section, adjacent openings which may be open at the edge can each be separated by a web formed by one of the laterally attached legs of the associated U-shaped profiled partition.
  • the molded insulating parts described above are generally in one piece. Multi-piece insulation elements can also be used for certain chokes or transformers elements for the winding heads can be used with advantage.
  • a cover cap made of insulating material which surrounds the insulating molded part at the top and laterally, can be pushed onto the molded insulating part described, the side walls of which close the lateral openings delimited by the outer wall and the adjacent end wall of the laminated core instead of the side walls of the insulating part (FIGS. 3, 4). . It is particularly expedient if the cover cap has connection devices for the wire ends of the coils and between the outer wall of the molded insulating part and a facing wall of the cover cap.
  • Insulated channels leading to the connection devices are formed for the individual wire ends of the coils, which are separated from one another by webs formed on the outer wall of the insulating material molded part or on the wall of the covering cap facing this.
  • the wire ends only have to be inserted into the channels, whereupon the cover cap is pushed on, which ensures perfect insulation of the connecting wires without the need for additional insulation measures of this kind.
  • the channels are provided between mutually assigned and adjacent side walls of the molded insulating part and the cover cap.
  • each winding head of each coil has its own insulating molded part plugged in such a way that the upper wall part of the insulating material part placed on the respective lower winding head forms a dividing wall that isolates the winding heads of two superposed coils and that the insulating material molded parts interacting in this way each Side of the laminated core are positively connected.
  • the assembly of the winding head insulation is particularly simple, because only the individual molded insulating parts are successively plugged onto the winding heads of the coils lying one above the other and then inserted into one another.
  • a symmetrical series reactor is shown, the winding of which consists of two separate coils 1, which have a substantially rectangular shape in the manner shown in FIG. 1 and which are arranged one inside the other in the manner shown in the two figures are.

  • the side walls 12 with the strip-like widenings 13 can also be omitted, which also applies to the upper wall 11 except for a web connecting the tongue 9 to the outer wall 10.
  • the tongue 9, the wall thickness of which is generally greater than that of the outer wall 10, as shown, can be of solid construction or divided into individual fingers lying next to one another. It is only essential that the tongue keeps the winding head 2a at a distance from the end wall of the laminated core 5.
  • the winding heads 1a, 2a are covered laterally by the side walls 12 and the upper wall 11.
  • the side walls 12 can be extended in the manner indicated by dashed lines in FIG. 2 down to a mounting rail 14 which closes the lower opening 15 delimited by the outer wall 10, the side walls 12 and the end face of the laminated core 5.
  • this lower opening 15 can remain open or in which the lateral covering - with the omission of the side walls 12 and possibly the upper wall 11, is carried out, for example, by means of an advanced sheet metal jacket connected to the laminated core 5.
