The other ends of the contact elements (32) have pairs of insulation displacement contact parts (28). The pairs of contact parts (28) enable two wires to be connected to each contact element (32). The contact elements (32) are formed from blanks (56a, 56b) stamped from a strip as a lead frame 54. Contact portions (38), on which each pair of contact parts (28) are formed, are formed in rows at each edge of the lead frame strip, with the spring contact portions (40) extending inwardly from the strip edges at 45° to the strip edges.

Abstract: A communication cabling system wherein elongate communication distribution assemblies (CDAs) are joined serially together by connector units at opposite ends thereof. The interconnected CDAs include access ports or openings into which a tap unit may be inserted and connected to a circuit which is accessible through the access port. Each CDA can be adapted to carry a selected number of circuits wherein each connector unit at an opposite end of a CDA includes a block-like shielded housing having a predetermined number of mounting sockets on a back end thereof. A plurality of modular cable assemblies are provided which have plugs that plug into a respective one of the mounting sockets of the shielded housing so as to assemble a CDA. This system provides for the ready construction, installation and reconfiguration of the communication cabling system.

Abstract: A terminal, isolating or connecting strip for telecommunications and data technology, having contact elements and having a mounting apparatus.

Abstract: The invention relates to an arrangement of at least two contact pairs (1, 2; 3, 4) for compensation of near-end crosstalk, in which one or both contacts (1, 2 or 3, 4) of a contact pair (1, 2; 3, 4) are designed to be angled away once or more than once from a contact region (5), with the result that the contacts (1, 2 and 3, 4) then run parallel once more and the distance between the contacts (1, 3 and 2, 4) of different contact pairs is designed such that crosstalk which is in antiphase with the contact region (5) is produced.

Abstract: An arrangement of contact pairs of twin conductors and of conductors of a multi-core cable for the purpose of reducing crosstalk, in which the contact pairs of the twin conductors or the conductor pairs define mutually parallel, non-congruent areas F.sub.1,2 ; F.sub.3,4 ; F.sub.5,6 ; F.sub.7,8, and the twin conductors or, conductor pairs are arranged on electric equipotential lines of their neighboring twin conductors.

Abstract: A clamping device, in particular a cable clamping device for telecommunications technology and data systems technology. The clamping device is of a generic type which ensures that objects having different diameters are clamped simply and reliably and without the risk of an impermissibly high degree of pinching of the object to be clamped. The clamping device includes a clamping member, which is formed from a basic body and at least one clamping arm and into which the object to be clamped is inserted. The clamping member is pushed into a sleeve having cutouts in which at least one of the clamping arms of the clamping member engages. By rotating the sleeve with respect to the fixed basic body at least one of the clamping arms reduces the clamping inside diameter of the clamping member.

Abstract: A printed-circuit board and a method for the precise assembly of electronic components on a surface of the printed-circuit board, the electronic components being electrically and conductively attached to printed-circuit board by a reflow soldering technique. For this purpose, a printed-circuit board is used that has sections for receiving electronic components on its surface. The sections being at least partially adapted to the outside contour of respective electronic components. The sections are configured as slotted contours or grooves and shaped to secure that the electronic components mounted after the application of solder paste are held in their desired positions prior to the actual soldering process. In addition, the assembled printed-circuit board can be connected to a housing composed of dome-type extensions of an at least partly deformable material. The extensions engage in cutouts provided in the printed-circuit board and pass through the latter.

Abstract: A connection element having electric insulation-piercing terminal contact elements in a chamber of a receptacle part intended for the connection of electric conductors without stripping them. A sliding part is provided enclosing a part of the insulation-piercing terminal contact elements arranged in the chamber. The connection element permits easy and reliable connection of electrical insulated conductors without a special connecting tool and at the same time ensures as high a current-carrying capacity of the conductor as possible. A locating opening for the conductors is made in a sliding part 1 in an inclined position relative to the longitudinal axis of the sliding part, which longitudinal axis is at the same time the longitudinal axis of the chamber. The conductors are inserted into the insulation-piercing terminal connecting contacts, set at an angle to the wall of the chamber, and make electrical contact with the insulation-piercing terminal connection contacts.

Abstract: An overvoltage protection plug is provided, including at least one voltage-limiting component with an associated fuse element and a fail-safe device (6). The fuse element trips the fail-safe device (6) in the event of thermal overheating. The fail-safe device can optionally be upgraded with visual fail-safe signaling, wherein the voltage-limiting component is arranged with the associated fuse element and the fail-safe device (6) as an enclosed unit on a first printed circuit board (3) to which, optionally, the visual fail-safe signaling, which is arranged on a separate, second printed circuit board (10), can be assigned.

Abstract: An earthing module for the termination of earthing conductors to contact elements and for latching on rails, where quick, convenient and reliable connection and disconnection of one or several earthing lines is possible for a large range of wired diameters. An earthing plate is connected on either side optionally to a known insulation displacement contact with inclined insertion portion via a central tapping portion or to a screw contact terminal or on its one side to an insulation displacement contact with inclined insertion portion via the central tapping portion 15 thereof and on its other side to a screw contact terminal.

Abstract: An overvoltage protective module comprising a base body made of plastic with embedded contact strips, overvoltage suppressers arranged on the top of the base body and provided with fuse elements, and contact springs which hold the overvoltage suppressers and the fuse elements on the base body and are used to make contact with the contact strips when a fuse element softens in response to an overvoltage. In order to simplify the structure of such an overvoltage protective module, the contact springs (5) are formed on a spring comb (7) which can be clamped onto the top (6) of the base body (1) and whose web (8) which holds the contact springs (5) has at least one spring contact (9) for making contact with a ground conductor (10).

Abstract: The invention relates to a management-capable splice cassette for the telecommunication and data technique, for receiving carrier shells for two glass fibers each. A housing is provided with a cable connection device and a carrier is connected to said housing. The carrier shells are connected to the carrier in a rotatable manner. The management-capable splice cassette is exchangeable with other splice cassettes and can in particular be inserted in prior art splice cassette housings instead of the conventional splice cassettes. The invention provides an available reserve length and a small constructional height as well as an economical and simple handling. The carrier shells are disposed in at least two adjacent receiving portions and stacked upon each other, each of carrier shells is rotatably supported into a latch position at one of their sides.

Abstract: A device for the protection of cables laid in switch cabinets, other equipment or the like, in order to prevent bends below a minimum bending radius at the exits of cable ducts or similar equipment and that prevents corresponding damages. At the exit openings of cable ducts guiding devices are provided and configured such that they prevent falling below the critical bending radius and that they widen in the direction of exit and are rounded.
