Abstract: An electrical connector for establishing an electrical connection to an electrical conductor. The connector includes a connector body with a cylindrical hull or recess for receiving the electrical conductor with an insulating layer. A contact screw is positioned in the connector body and the contact screw includes an end portion for displacing or piercing the insulating layer of the insulated conductor.
Abstract: A method for the protection of in particular telecommunication installations against overvoltage and overcurrent by overvoltage arresters, PTC resistors and voltage-limiting components and to a protection circuit for carrying-out the method. The object of the invention, namely to develop a method and a circuit in particular for the protection of telecommunication installations against overvoltage and overcurrent that secures a surge-current resistant and reversible line protection, is achieved by the response voltage of the overvoltage arrester being higher than the peak value of a powersupply voltage, and that the response voltage of the thyristor diodes selected being slightly above the maximum operating voltage values of the line to be protected. The PTC resistors are used as a decoupling member to block the maximum amplitudes of the power supply voltage.
Abstract: A termination device for telecommunication and data transmission applications, comprising a carrier rail, a base element with a receiving opening and functional modules. Various termination tasks can be solved by the base element being latched or onto or held by the carrier rail. Receiving portions for a termination element for incoming cables and for a termination element for outgoing cables are provided in the base element. A functional module is disposed between the two termination elements.
Abstract: A distribution block for telecommunication and data transmission applications, in particular for the main distribution frame of telephone and data lines. The distribution block includes insulation displacement contact elements for the connection of the subscriber cables as well as of the exchange office cables. One-piece contact springs are disposed in the interior of the modular-design distribution block. A mounting bracket, in particular for receiving distribution blocks is provided including a U-shaped tub. A device for guiding cables is rotatably moved in a partial section, and with cable guide portions. A reduction in size, an improvement of connection tasks, the individual protection of double wires, a reliable grounding and a cable guiding which is substantially resistant to buckling and bending are secured, is achieved by that one-piece contact springs disposed in the interior of distribution block.
Abstract: A grounding bracket, in particular for use in a connecting device for telecommunication and data transmission applications, in particular mounted on a hat-type rail as a carrier rail. An easy-to-replace grounding bracket for connecting devices is provided with different grounding tasks being possible in a simple way. Spring elements for resiliently latching in hat-type rail, a contact lug bent out from a bracket bottom and fastening elements for safe attachment at a bottom of a connecting device of telecommunication and data transmission applications are provided.
Abstract: A local ISDN transmission system has a central base station and a number of subscriber radio terminals greater than the number of communication channels. The system is connectable to subscriber ports through an S.sub.0 wireless transmission interface and is responsive to an activation request from a subscriber radio terminal for opening any available and free communication channel for a communication. An intermediate generator in the base station and in each subscriber terminal divides an ISDN two-wire subscriber connection line between a line termination section and a network termination section communicating by radio transmission. The intermediate generator, upon the occurrence of an activation request by a subscriber terminal, allocates a communication channel within waiting and monitoring periods for the activation of the ISDN two-wire subscriber connecting line.

Abstract: A mounting device for communication voice/data RJ connection elements (patch panel). A simple, quick, reliable and flexible placement of RJ connection elements and the wiring thereof is achieved with a mounting panel with receiving portions and with recesses, in which the RJ connection elements are immediately placed. A rear-side cable guiding portion spatially corresponding to the respective receiving portions.The rear-side cable guiding portion rotates between a swung-in and a swung-out position to allow access to the cables. The mounting device also has a cable guiding ring attached to the front side.
Abstract: An automatic rearrangement and distribution device for telecommunication and data lines with connection terminals for exchange office and subscriber lines and a remote controllable connection device having a gripping element. To automate a re-arrangement and distribution device provided with connection blocks, the connection terminals are disposed in connection blocks radially directed relative to a central axis. The connection device is swingable in central axis, and a gripping element is disposed radially displaceably at the connection device. For connecting the rearrangement and distribution device to copper cables as well as to fiber-glass cables, without modifications being required, the control paths at blocks for fiber-glass and for copper cable applications have identical lengths.
Abstract: An electrical connector for use as a network terminating apparatus is provided including a front or cover plate assembly, an intermediate unit which in use is disposed behind the cover assembly and a backing unit. The intermediate unit carries diagnostic circuitry, an assembly of connecting devices, and one or more contact assemblies, and one or more sets of generally identical contact elements, which extend between and interconnect the elements carried by the intermediate unit. The connecting device may comprise a multi-way connector. Each contact may include an elongate strip-like, electrically conductive portion from which project, generally orthogonally, a plurality of contact arms, each the arm being disposed at a predetermined position so that it can make electrical contact with one of the elements carried by the intermediate unit. One of the contact arms may include an insulation displacement type contact.
