  • the object of the invention is to fix a structural unit self-centering in a receiving opening, with comparatively large tolerances with regard to the dimensions of the structural unit and the receiving opening being permissible.
  • a major advantage of The invention consists in that the preferably axially extending crush ribs exert radial forces on the structural unit due to their at least partially elastic deformation, which fix them centrally. This allows relatively large tolerances to be compensated for between the joining partners (unit and opening). Due to the relatively easy deformability of the ribs, in spite of large tolerances, only comparatively small differences in the press-in forces can be expected during the insertion of the assembly.
  • the interstices remaining between adjacent ribs are filled with a hardenable or hardening compound.
  • a tight connection between the joining partners is ensured with simple means, so that overall a tight seal of the interior of the housing from the external environment can be achieved.
  • the ribs consist of an electrically conductive material or are metalized.
  • a method for fixing an electrical assembly, in particular an electro-optical coupling unit, in a receiving opening, in particular in a housing wall provides according to the invention that ribs projecting radially into the receiving opening are formed and that the ribs are deformed elastically or elastoplastic when the assembly is inserted into the receiving opening, whereby the assembly is fixed.
  • This method allows comparatively large tolerances between the dimensions of the joining partners.
  • the axial insertion of the structural unit is ensured by the elastic or elastoplastic deformation of the ribs with an approximately constant press-in force.
  • the ribs automatically center the structural unit with respect to the receiving opening and hold it sufficiently in this.
  • a production-technically preferred embodiment of the method according to the invention provides that in the transition area between a housing wall having the receiving opening and an adjacent housing wall or the housing base. a receiving space is formed on the inside of the housing, that a potting compound is first introduced into the receiving space and that the housing is then pivoted such that the potting compound runs from the receiving space to the receiving opening.
  • a comparatively large application space is available for the casting compound, so that the casting compound can be applied by inexperienced personnel or with a simple, relatively imprecise device.
  • the potting compound then runs to the receiving opening and, when the assembly is inserted, fills in the remaining spaces between adjacent ribs. This is particularly advantageous in the case of an arrangement of the receiving opening that is difficult to access from the interior of the housing.

  • FIG. 2 shows a section of an end view of the assembly according to FIG. 1 with the pressed-in structural unit 20.
  • the ribs 10 When the structural unit 20 is pressed in, the ribs 10 are deformed elastically and / or elastoplastically, their rib peaks 10a increasing the clear width of the opening receiving opening are deformed by the sleeve 14.
  • the rib peaks 10a are thereby pushed back to a common circumferential circle which corresponds to the circumferential circle of the sleeve, while the rib peaks 10a lay before the insertion of the assembly on a circumferential circle with a smaller diameter than the diameter of the sleeve 14.

  • FIG. 4 omits the housing cover 1b (FIG. 1) and a circuit board arranged in the interior 44 of the housing 1 with control circuits which are connected to the connections 25, 26 of the structural units 20, 22.

  • the potting compound 32 runs from the receiving space 50 into the spaces formed between the structural units 20, 22 and the receiving openings 6, 8.
  • the potting compound can harden there by itself or initiated.
  • the manufacturing costs can be considerably reduced because the deformability of the crimp ribs has relatively large tolerances between the geometries of the joining partners involved (structural units 20, 22 and receiving openings) 6, 8) compensated. Despite the large tolerances, the press-in forces for inserting the structural units 20, 22 are approximately constant. As a result, housings produced in particular by injection molding can be used, so that there are considerable cost advantages compared to machined housings with machined receiving openings.
