Abstract: A device (1) for cleaning an optical waveguide end (2) comprises a guide portion (3) for receiving the optical waveguide end (2) in a stable position and a rotatably mounted spool (4) onto which a flexible cleaning element (5) is wound. The guide portion (3) and the spool (4) are positioned relative to one another such that an optical waveguide end (2) received by the guide portion (3) is able to be pressed against the wound cleaning element (5). The cleaning element (5) is able to be unwound from the spool (4) such that different portions of the cleaning element (5) are able to be applied to the optical waveguide end (2) during unwinding.

Abstract: A plug part for a plug-in connection, in particular of optical conductors, includes a plug housing, in which a plug insert having at least one plug pin for receiving a conductor is arranged. The plug part can be inserted into a correspondingly designed socket part in an insertion direction (A), and includes a locking means for releasably locking the plug part in the socket part. The plug part further has an unlocking means, by means of which the locking of the locking means to the socket part can be released. The plug part includes a protective apparatus for protecting the end face of the plug pin and for moving from a closed position with a covered end face to an open position with an exposed end face by inserting the plug part into the socket part by interacting with the socket part.

Abstract: A connector part for an optical plug-in connection includes a connector pin, in which an optical waveguide stub extending over a longitudinal center axis is held, and a sleeve-like pin holder. The pin holder includes a pin accommodating section, in which the connector pin is held, and an optical waveguide accommodating section, to which the end of an optical waveguide cable can be fixed in a tension-resistant manner. The optical waveguide accommodating section includes at least two jacket parts that can be connected to each other, wherein at least one jacket part can be fastened to the pin accommodating section using a joint so that the jacket part can be swiveled about a certain swivel angle between an open position and a closed position. The optical waveguide stub can be welded to an optical waveguide end on the cable side.

Abstract: The invention relates to a device for splicing fiber optic lines having a first and second holder for direct or indirect receiving of at least one fiber optic line each, an alignment means for aligning the ends of the fiber optic lines received in the first and in the second holder to one another and electrodes in the region of the ends of the fiber optic lines aligned to one another for creating a slice connection. The two holders on one side and the alignment means and preferably the electrodes on the other side can move relative to one another between a splicing position and a release position such that the splice connection is released in the release position.

Abstract: A plug part (1) for an optical plug connection comprises one pin holder (3) in which a plug pin (2) for retaining an optical waveguide which extends over a longitudinal central axis (L) is held. The pin holder (3) can be pushed into a plug housing (4) via a cable-side opening (30) and locked therein in a mounting position, wherein the plug pin (2) is held axially resiliently in the plug housing (4) with the aid of a separate spring element (5). The spring element (5) can here be inserted in a mount in the plug housing (4) before the pin holder (3) is pushed in. The spring element (5) is secured by way of a clamping sleeve (6) which can be inserted into the mount via the plug-side opening (30) in the push-in direction (e). Arranged in the mount is a circlip (7) and the pin holder (3) has a groove (12) which can be brought into engagement with the circlip (7) in a latching manner in order to fix the mounting position.

Abstract: A connecting part (1) for an optical connection of a first optical fiber (2) to a second optical fiber (3) comprises a sleeve-like cable mount (4) having a first cable receiving section (5), in which the first optical fiber (2) can be housed, and a second cable receiving fiber section (6), in which the second optical fiber (3) can be housed. The optical fiber ends (23, 24) of the two optical fibers (2, 3) can be welded together. Therefore, the second cable receiving section (6) is designed along the median longitudinal axis (L) in such a way, that it can be assembled and comprises a casing part (10, 10?) pivotable about a hinge (1). The weld joint is located within the pivoting range of the casing part. The cable mount comprises a screw-on coupling sleeve (8) for covering and fixation.

Abstract: The invention relates to foldable spectacles comprising two lenses (1a, 1b) which can be adjusted between a support position and a folded position and which are connected to each other by means of a nose piece (10). The nose piece (10) extends on a connecting axis (I) which is arranged on a plane of the spectacle lens and comprises a folding joint (15) which is used to fold the spectacles. The folding joint (15) can be rotated about a rotatable axis (m) which extends at an acute angle (?) to the connecting axis (1), such that the spectacle lenses (1a, 1b) are arranged on the same plane next to each other in a folded position after a 180° rotation.
