Distribution device for the telecommunication and data technique

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.

Automatic re-arrangement and distribution device for telecommunication

A distribution device, in particular for the main distribution of telephone and data lines, includes a distribution rack, a distribution frame, and a pivotable frame, for terminating the system side and the subscriber side. Jumper possibilities and the adaptation to the possibilities of computer-controlled exchange systems are improved by disposing the subscriber side and the system side-by-side in a modular manner on a profile frame, and building them up vertically above each other to frame rows disposed side-by-side.

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.

A heat protection device for overvoltage terminal block arrester magazines having with two-way arresters or with button arresters. According to the present invention, an S-shaped clip spring or an L-shaped clip spring is inserted in a button arrester of the 6.times.6-type or the 6.times.8-type. The clip provides one leg of the protection device having a solder preform and a switch contact to complete the circuit. In case of an overvoltage, the arc developed in the arrester causes the solder preform to melt off during an extended application of heat arising from the arrester, activating the switch contact and short-circuiting the leg of the arrester.
