Definitions

  • the invention relates to a plastic cup with a ring core choke cast into the plastic cup, the winding ends of which are contacted with the connecting pins cast into the cup wall and with a curved plastic cup base, on the curved outer wall of which standing bodies are formed and whose curvature is at least approximately adapted to the radius of curvature of the ring core choke.
  • the US-A-3 845 435 shows approximately a plastic cup of this type, in which, however, several individual containers, each intended for receiving throttles, are combined and equipped with common stands.
  • the standing bodies do not protrude beyond the outer wall of the cup base; there is also no surface parallel to the stand for stamping.
  • plastic cups are not only characterized by a reduced volume and thus by a reduced absorption capacity for the sealing compound, in addition, the weight of the finished structural units is also considerably reduced.
  • the present invention has for its object to provide a plastic cup of the type mentioned, which is not only characterized by the aforementioned high stability and savings in potting compound, but is also designed so that an indelible and easy lettering or stamping of the cup is possible.
  • the invention proposes, in the case of a plastic cup of the type mentioned, that the standing bodies are designed as parallel ribs with standing surfaces parallel to the free cup front side, that the standing areas protrude beyond the outer wall of the plastic cup bottom and that the outer wall of the plastic cup bottom in the middle of the cup bottom has a surface parallel to the standing surfaces.
  • This area can be used to identify the toroidal choke, the labeling, for. B. type designation, stamped on this surface or molded onto this surface in one step with the production of the plastic cup. Since this area is set back from the stand area, the lettering is secured against dirt or damage to the writing.
  • the plastic cup 1 shown in the figures carries electrical connection pins 2 cast into its wall for contacting the winding ends of an annular core choke, not shown in the drawing.
  • the bottom of the plastic cup 1 is, as indicated at 3, curved, its radius of curvature preferably being adapted to the radius of curvature of the toroidal core choke.
  • the outer wall of the plastic cup base in the center of the cup base is designed as a surface 4 parallel to the standing surfaces.
  • This area is the carrier of a stamped or possibly molded lettering, eg. B. Marking the toroidal choke, suitable.
