  • Patent number: 11557847
    Abstract: Embodiments of a securing system for plug connectors may have an adapter and a pair of housing parts, each with at least one plug place with a plug place interface for receiving the adapter whose exterior may have an adapter interface for positioning in the plug space. The adapter may have an interior geometry for receiving a plug connector. The exterior of the adapter and the plug place may form a primary securing means for securing the adapter in the respective plug place when the adapter is inserted into a defined plug position to secure the adapter in the plug place. Embodiments may include a secondary securing means, which can be plugged into the housing part up to a defined end position at which the secondary securing device to secure the plug connector in the adapter.

  • Patent number: 6960027
    Abstract: A ferrule (4) for an optical waveguide (1), according to the invention, is characterised in that the ferrule (4) is made of plastics material, and in that the ferrule (4) is for example more transparent than the casing (2, 3) of the optical waveguide (1). The process according to the invention, for fixing a ferrule (4) to an optical waveguide (1), includes the following steps: stripping certain regions of an outer casing (2) of one end of the optical waveguide (1) and exposing an inner casing (3) of the optical waveguide (1); pushing the ferrule (4) onto the stripped region of the optical waveguide (1); and welding the ferrule (4), at least in certain regions, onto the surface of contact with the inner casing (3) of the optical waveguide (1). Because of the transparency of this ferrule (4), the laser light can almost completely penetrate the ferrule (4) in the so-called transmission technique and take effect in the outermost region of the casing (2, 3) of the optical waveguide (1).

  • Patent number: 6913393
    Abstract: A plug for a connector arrangement consisting of a plug and an associated mating plug, has a housing which has at least one axial receiver for an optical fiber and a protective device movably mounted in the housing for protecting the optical fiber. The protective device according to the invention is designed as a slide which can be moved axially to the receiver and the slide has a aperture for the optical fiber and/or the receiver.

  • Patent number: 6793404
    Abstract: The invention relates to an optical connector housing (100) for connecting an optical fiber to an optical element, such as a diode or a further optical fiber. The housing (100) comprises a substantially tubular receptacle (102) for one or more optical fibers and a retention member (104), which is received with interlocking fit in the housing (100) and is displaceable vertically to the optical fiber. In order to provide a housing (100) which fixes the optical fiber easily and inexpensively, yet securely, according to the invention the retention member (104) is manufactured from the same material and integrally with the housing (100). In the pre-assembly position, the retention member (104) is supported by webs (106) on the housing (100). During assembly, the retention member (104) is displaced in such a way that it engages the optical fiber and secures it against axial displacement.
