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. These springs are formed by insulation displacement connection contacts at the front and rear sides of the block by a telephone contact in a central section, the phone contact being composed of at least two contact surfaces which may be double contacts, and by a support surface. A tongue acts on the support surface with a cam. A tapping contact is provided in the front section of contact spring. A mounting bracket is provided with a tub bottom and contact lugs for the establishment of an electrically conducting and of a mechanical connection and openings for the insertion of protection plugs or the like. A device for guiding cables is provided including a rack frame or the like rigidly disposed cable guide portions that are positioned upwardly and downwardly offset to cable guide portions.

Distribution device for the telecommunication and data technique

An over-voltage protection plug for telecommunication installations, including a housing with a printed-circuit board, a voltagesurge suppressor, a slider, a spring, an earth plate, a signalling element. Reliable protection against voltage surges is provided, wherein the solder position is loaded to a minimum extent only. The plug is composed of few parts only and further permits automated manufacture at low cost, and which clearly shows the tripped condition at the outside. The slider is pre-loaded over a support face and over an edge at the inner housing wall in the housing by the spring. A shaped part of solder material is loaded to a minimum extent only by the spring force (pressure force) of the slider.

Protection plug

A device for storing the single and bundle wires (16 or 5, respectively) of glass-fiber cables in distributor devices of telecommunication and data systems, comprising a casing (24), at least one cassette box pivotably mounted in the casing, and a splice cassette (10) mounted therein, is intended to be improved such that with a simplified construction of the cassette box and of the splice cassette (10), a break-proof support of the single and bundle wires (16 or 5, respectively) is permitted. For this purpose the cassette box is formed of a support plate cassette (10) and provided with a slot (12) for passing the single and/or bundle wires (16,5) through and with members located on both side faces for supporting the single or bundle wires (16, 5) respectively.

Device for storing the single and bundle wires of glass-fiber cables in

The invention relates to a switching assembly for glass fiber cables of the telecommunication and data technology field, and in particular to a glass fiber cable partitioning and terminal rack. The rack 1 includes a frame 3 supported by the rack 1. The frame 3 includes a jumper field 29 for glass fiber cable cores 8, 9 and at least one magazine 16 or 17 provided with slide-in openings 18 for splice cassettes 19. In similar prior art switching assemblies of this type, there is poor accessibility to the incoming and outgoing glass fiber cable cores 8, 9, thereby a high risk of breakage occurs during assembly, in particular when splicing. For avoiding these disadvantages, the invention provides that the frame 3 is supported at the rack 1 pivotally about a vertical axis 26, and that at the frame 3, a jumper field 29 with a patch field 6, 7 for the incoming and outgoing glass fiber cable cores 8,9 is accessible from the front 4 and from the back 5 of the frame 3. At least one magazine 16, 17 is provided, and the splice cassette slide-in openings 18 extend substantially parallel to the back 5 of the frame 3 and substantially vertically to the vertical axis 26 thereof on the opposed side of the frame 3.
