Definitions

  • the present invention relates to a cartridge receptacle, a lens plug component and a method for producing the cartridge receptacle according to the preambles of the independent claims.
  • WO 2007/119036 describes an optical connector for a fiber optic communication system.
  • a ferrule is glued in a housing. Until the adhesive has cured, the ferrule in the housing is free to move. During this time, the ferrule can be aligned relative to the housing.
  • both parts After gluing the ferrule into the housing, both parts must be fixed to each other until the adhesive has hardened. This production step increases the time required to produce a connector.
  • An object of the present invention is therefore to provide a cartridge receptacle in which the ferrule and housing need not be fixed during a curing process and the orientation of the cartridge is nevertheless determinable at least with regard to a part of the housing.

  • the lens-side end face allows probing, for example, in a CNC machine or a measuring machine, so that the position of the Pat ⁇ ronenfact and thus the position of the cartridge can be determined.
  • the optical axis of the cartridge can be determined in a particularly simple manner, ie with simple calculation steps.

  • the plug is securely received.
  • the lens plug component includes a lens holder against which the lens abuts. As a result, the position of the lens in the lens plug component is specified particularly accurately.
  • the above-mentioned object is also achieved by a Ver ⁇ drive for the production of the cartridge, wherein electromagnetic radiation (light, in particular white light) is injected into the cartridge, the optical axis of the cartridge is determined, and the lateral surface of the cartridge is machined so that its Central axis is parallel to the optical axis of the cartridge or identical to the optical axis of the cartridge.

  • the lateral surface of the cartridge may have a Fehlwinkel or a mispositioning to the optical axis of the cartridge. This would lead to a misalignment of the entire lens connector component after installation of the cartridge in the cartridge holder. Such circumstances would have a negative influence on the transfer result of the overall system.
  • the cartridge is clamped in a suitable device. With the help of this device possibly occurring incorrect positioning can be corrected. In the corrected position, the lateral surface of the cartridge is revised, so that fall after processing, the cylinder axis of the lateral surface of the cartridge and the optical axis together.
