Abstract: In order to advantageously weld a pre-mounted connector-plug part (1) to an optical waveguide cable, the connector-plug part is provided with a pin holder (4) receiving a connector-plug pin (2) on a pin receiving section (5). Preferably, two cladding parts (8, 8?) form a cable receiving section (6) in said pin holder. In order to carry out welding in a simple manner on the bare end (22) of the end of a fiber, the cladding parts (8, 8?) can be pivoted around a hinge (9, 9?) between an open position and a closed position.

Abstract: The invention relates to a plug-in element (1) for an optical plug-in connection. Said element comprises a connector pin (2), which is held in a guide sleeve (4) by axial spring-loaded prestress, in such a way that it can be displaced in a limited manner along its longitudinal axis (3). The guide sleeve consists of at least two casing elements (5, 5?) that can be assembled along their longitudinal axes. Said casing elements significantly simplify the production and assembly, as no screw or adhesive connections are required.

Abstract: An optical plug connection (1) consists of a sleeve portion (2) and a plug portion (3). The sleeve portion (2) comprises a sleeve housing (4), the insert openings (5) of which are closed by protecting flaps (6) with spring action. These are formed as a bent component made of metal and are flexibly latched at the sleeve housing. For a better handling of the locking element (21) a separate gripper part (22) can be snapped onto the plug portion (3).

Abstract: A plug-and-socket connection includes a socket part on a mother board and a plug part on a daughter board. The plug part comprises a plug housing axially displaceably mounted on a daughter board. A securing mechanism latches the socket part in a latched position. The plug housing, in the insertion direction, is directly or indirectly supported on a push element in the form of a leaf spring with an angled part. The spring force of this leaf spring maintains the support until reaching the latching position. With a continued pushing movement, the support is automatically released by yielding of the leaf spring. In this manner the daughter board, after reaching the latching position, may be decoupled from the mother board.

Abstract: For the pull-proof locking of a plug part (1) into a socket part there is provided a locking element (27) which on a rotational link (39) is pivotably fastened on a plug part and which is resiliently supported on the plug housing. The locking element is advantageously snapped onto the plug housing and is formed of a bending part of metal.

Abstract: A plug part (1) for an optical plug-and-socket connection includes a plug housing (2) and at least one plug pin (3) which is held rotationally fixed in the plug housing on a pin mounting (4). The pin mounting at the same time is under axial spring bias. It is held rotationally fixed in a sleeve (6) which is fastened on a cable-side housing terminal part (7). A positioning section (8) permits the fixing of the radial relative position on a complementary positioning section on the plug housing (2). The optimal relative position is with this previously evaluated with a measuring adapter. The thus formed cable terminal unit (26) may thus be easily assembled and handled and manufactured with a fiber optic cable.

Abstract: A plug part (1) for a combined optical and electrical plug-and socket connection has a plug housing (3) in which at least one plug pin with a light-wave guide is held. The cable (30) contains apart from a light-wave guide also yet at least one electrical lead, wherein the electrical contact is created via a contact element (13) which is held on the outside on the plug housing (3) and which extends in the plug longitudinal direction roughly parallel to the middle axis (29) of the plug pin. The contact element (4) is protected from external influences by a protective element (6) which may be snapped onto the plug housing (3).

Abstract: An insert-rack plug connection can be created between at least one sleeve portion (2) on a relatively fixed-position mother board (3) and at least one plug portion (4) on a relatively mobile daughter board (5). With that, the plug arrangement comprises a plug housing (6) mounted to displace axially on the daughter board and possessing a plug ferrule (7) mounted under preloaded axial spring tension. In addition, engagement means (8) for engagement of the plug housing into an engagement position in the sleeve portion are provided on the plug housing. In the insertion direction (x), the plug housing (6) is supported either directly of indirectly on a spring-action thrust element (9), the spring force of said thrust element maintaining the support until the engagement position has been reached, and subsequently automatically releasing said support on continued thrust movement.

Abstract: A sleeve part (1) for a plug connection for fiber optics is provided with an opening (2) for accommodating a plug part (21). The plug part (21) is insertable in the direction of an insertion axis (A) into the sleeve part (1). The sleeve part comprises a sleeve (3) for receiving a plug pin of the plug part (21). The sleeve part (1) is furthermore provided with a securing element (4) with a coding consisting of projections (5) and/or reliefs (6). The securement section (4) is arranged on at least one separately formed coding element (7, 7′). The coding element (7, 7′) in a snap-on direction (R) roughly perpendicular to the insertion axis (A) can be snapped on the sleeve part (3).

Abstract: A protective flap (5) is arranged on the end of a lever arm formed as a flexible spring on the plug casing (2) of a plug (1, 1'), said protective flap covering the face and the end surfaces of an optical fiber. The lever arm is connected to the plug casing so as to be removable, and is shaped and arranged in such a way that the protective flap is pressed against the face under spring tension when in the closed position. With that, the protective flap assumes not only a screening function to guard against the escape of light, but also practically hermetically closes off the face and thus prevents dirt entering between the protective flap and the face.

Abstract: A plug portion (1) for an optical plug connector has a plug casing (2) in which at least one connector pin (3) is held. A protective flap (4) for protection of the connector pin is pressed under spring tension against the face (7) of the plug casing. The protective flap is mounted to pivot and slide on an approximately linear guide path (5) in such a way that, on insertion of the plug portion into a sleeve portion, it is able to move from a closed position on the face of the plug casing into an opened position that is set back in relation to the face (7). In order to pre-load the protective flap under spring tension throughout its entire slide- and pivoting-travel, a compression spring is arranged on the plug casing (2) approximately parallel to the guide path (5), said compression spring impinging either directly or indirectly upon the protective flap (4) above the plane of the guide path (5) between the closed position and the opened position.

Abstract: The plug arrangement (1) has two individual plugs (2, 2') that can be extracted solely by actuating a single release lever (3). At the same time, this release lever connects combines the plugs to a duplex plug unit. To improve axis parallelity. a connecting element (6) is additionally snapped onto both the plugs.

Abstract: An adaptor (1) can be releasably connected to a fixed plug portion (13 or 21). The fixed plug portion is, with that, for example a component in a measuring device for taking measurements on differing optical fibers. The adaptor is provided with a sleeve (3) in which various transferable plug portions can be temporarily inserted. The sleeve has an axially parallel slot (6) for accommodating a rotational security device on an initial category of fixed plug portions (21). Additionally, the sleeve also has at least one further recess (4, 4, 5) on its outer casing for accommodation of the rotational security device (19, 19', 20) of a second category of fixed plug portions (13). In this way, an interface between adaptor (1) and fixed plug portion (13, 21) is created, which indeed enables combination with an adaptor equipped in the same way, although an adaptor without an additional recess is only able to be placed on one of the two categories.
