Abstract:
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.
Abstract:
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.

Abstract:
An electrical crimp connector has a plurality of two armed connecting elements made of a flat resilient contact material having a central slot. The main part of each slot extends from a widened entry aperture, is bounded by sharp edges and has a width less than the thickness of the metal core of a wire so that when the wire is pushed into the slot the insulation of wire is severed so the wire contacts the connecting element. A clamping element is associated with each connecting element and has a support surface on which the connecting element is fixed. The connecting elements are interconnected in pairs and have a number of interconnected clamping elements extending around them and are combined to form a unit having wire guides. The connecting elements are adapted to be plugged in on the support strip which is releasably connected to the insulating member on both sides of longitudinally extending lines, separate wire guides being provided on the parts which are releasable from one another.
