  • Patent number: 8969742
    Abstract: A cable gland including a screw sleeve which can be inserted into a wall or a pipe coupling is provided. A union nut interacts with the screw sleeve, and a clamping insert is acted on by the union nut and is adapted to be pressed against a cable which is to be retained by tightening the union nut. The cable has a reinforcement and a clamping device for clamping a portion of the reinforcement is provided in the cable gland. The clamping device partially engages in the screw sleeve in an axial direction in a use position and is acted on by the union nut outside the screw sleeve. A portion of the clamping device engages in the screw sleeve and acts in an interlocking manner on an inner face of the screw sleeve in the rotation direction in the use position.

  • Publication number: 20140127933
    Abstract: The invention relates to a plug-in connector (1) having a receiving sleeve (2) which encloses an insulation for the contacts (4), and a plug-in portion (3) which can be assembled with said sleeve and which also encloses an insulation (5) for counter contacts (6), wherein said plug-in connector can be coupled and attached in the inserted position without requiring a threading having a counter threading or having a counter nut. For this purpose, the outer side of the plug-in portion (3) and the inner side of the receiving sleeve (2) each have a non-round cross section in some regions on a rotating sleeve (7) which is rotatable relative to the receiving sleeve (2). Said non-round cross sections of the plug regions that can be inserted into one another fit together in a form-fit manner in the peripheral direction, and thus enable assembly in the position of use thereof.

  • Patent number: 8690599
    Abstract: A cable gland (1) for a shielded cable (2), including a threaded sleeve (9), a clamping insert (4) that engages therein, and a union nut (7) or pressure screw in the usual manner. The union nut or pressure screw act axially and radially upon an area of the clamping insert (4) protruding beyond the threaded sleeve (9) and radially deforms the clamping area or the clamping finger (6) of the clamping insert. The threaded sleeve (9) contains a contact device (10) having one or more contact fingers (11), which lie against the shielding of the cable (2) in a contacting manner in the working position.

  • Publication number: 20130020124
    Abstract: A cable gland (1) has a screw sleeve (2) which can be inserted into a wall or a pipe coupling and has an external thread, and has a union nut (3) which interacts with the external thread of the screw sleeve (2). The union nut (3) can be used, by virtue of being tightened, to press a clamping insert (5) against a cable (4) which is to be retained, wherein the cable (4) has a reinforcement means (7) which is exposed at least at points or is free within the cable gland (1). A clamping device (8) for clamping a portion of this reinforcement means (7) is provided in the cable gland (1), the clamping device (8) partially engaging in the inner opening in the screw sleeve (2) in the axial direction in the use position and being directly or indirectly acted on by the union nut (3) outside the screw sleeve (2).

  • Patent number: 8172595
    Abstract: A connector (1) impermeable to liquids, having two matching connector parts (3) and (5), which is sealed in a connected position by at least one peripherally extending circumferential sealing ring (6) provided between the connector pats (3) and (5). The plug-in position is secured by a rotatable, axially fixed threaded bushing (8), which is fixed in the axial direction, but rotatably supported on one of the connector parts, and the internal thread (9) of which is mated to the holding thread (10) on the other connector part. A further thread or projection or threaded part (12) mating with the interior thread (9) is provided in a loosening direction at a distance from the holding thread (10) interacting with the threaded bushing (8), and a distance A from the end of the holding thread (10) to that of the further thread (12) is greater than a plug-in depth of the connecting pins (2) into the bushings (4).

  • Patent number: 7850485
    Abstract: A plug connector having a housing located at a plate opening in an operating position, and the plug connector contains wires and/or braids of a cable and electrical contacts. Assembly on the plate is realized by a flange plate attached to the outside of the housing having an interior recess with an interior dimension for engaging the housing of the plug connector. The flange plate is constructed as a single piece, and one of the interior recesses has a continuous slot extending to the outside, which slot acts as a clamp slot with the interior dimension of the interior recess being made smaller by narrowing the slot, and an arrangement is provided, by which the flange plate can be pressed in and thus clamped onto the outside of the housing. Preferably, the slot is reduced by at least one clamp screw with locking threads, or a lock nut.

  • Publication number: 20100253069
    Abstract: A connection fitting (1) for cables (23), tubes or the like includes a tensioning element (6) which is inserted into the opening (2) in a wall (3) and latches thereto. A screw sleeve (5) which is connected to a lock (13) is screwed onto the tensioning element (6), wherein the lock (13) engages in the tensioning element (6) in the position of use and locks the latching. Fitting onto the screw sleeve (5) is a union nut (4) which is used to actuate clamping lamellae (25) which are formed on the screw sleeve (5) and clamp the cable (23) or the tube or the like. The screw threads are in the same direction, with the result that, when the union nut is screwed against the tensioning element, the screw sleeve is concomitantly moved and the screw sleeve (5) is screwed against the tensioning element.

  • Patent number: 7422492
    Abstract: An angled plug-in connector (1) is provided having an insulating body that is located in a first angled limb (2) and that contains electric contacts. The conductor or conductors that extend from the insulating body extend through a second angled limb (3). The opposing end faces (2a, 3a) of the angled limbs (2,3) that lie in the angled region are oblique, generally forming a mitre and are interconnected by an articulation or in a detachable manner. At least one of the two angled limbs is provided with a recess or annular groove (10), which extends over the greater part of a circumference thereof, is open to an exterior over at least a part of its length, and in which a fitted spring-loaded ring (11) can be placed. The ring (11) is open or includes a gap (12) and has two end sections (13).

  • Patent number: 7338087
    Abstract: A connector fitting for fixing a longitudinal body, for example, a cable, a hose, a pipe, a corrugated hose to a wall opening. The connector fitting includes a chuck, which penetrates the opening and includes slits that extend in an axial direction. The chuck is radially outwardly expandable, in an insertion direction behind the opening into a clamping region containing the slits, and can be tightened on an outer side or in front of the opening of the housing by the thread and a matching tensioning nut, such that the clamping region can be withdrawn into the opening and thus braced against the longitudinal body. The tensioning nut includes an abutment acting in the axial direction and the chuck comprises a counter-abutment adjacent to its thread section, and the counter-abutment exerts pressure on the abutment in a released position of the chuck.
