Holder for the splice connections of fiber optic cables

around the fiber optic cables of two fiber optic cables connect, they have to be led to a splicer for fiber optic cables. There they are in suitably connected to one another, e.g. by fusing, in order to avoid repeating the splicing process to enable a stock length sufficient for 5 re-splicing should be taken into account. The connection point between two optical fibers must be against mechanical loads such as tension, bending, torsion and are protected against environmental influences. After connecting The fiber optic cable must be provided with a suitable splice protector, and the connection point and the ascenders of the optical waveguides are as ordered as possible in the area surrounding the connection point of the cables Housing can be stored. Minimum bending radii are allowed so that there are no impermissible increases in attenuation not be undercut.

For storing individual splice connections, it is known from DE-OS 3 217 320 to have flat shells open on one side to be used that can be pushed into the mounting frame. These pockets are used to store the stock lengths on its top side a rectangular opening through which the loops can be stored in the pocket. This known embodiment has the disadvantage that a Large number of optical fibers also have to be assigned a corresponding number of pockets that the splice point itself can not be stored protected in a separate carrier and that for the use of a 30th

A large number of pockets also have to be used in accordance with the number of frames.

The invention is based on the object of creating a receptacle for splice connections that is simple in construction which is the splicing of a plurality of Lieht waveguides of a cable and the accommodation of the Associated storage lengths in a simple manner and in the ascenders well ordered and safe, i.e. without danger of knee joints and the like, are to be accommodated,

dung according to the stated object is achieved by a box-f-like, open-top flat housing which on an end side close to the side walls with inlets for the cables and at the open top side of the sides walls inwardly protruding laser-like hold-down devices is provided.

The open housing gives a good overview of the inserted guide fibers and the tab-like hold-downs not only provide a secure hold, but also allow easy access to the individual lines.

It is advantageous to shape ribs or wall parts protruding from the bottom into the box-like housing in such a way that they form a natural curved contact surface for the inserted optical waveguides which may cooperate with sheet-shaped hold-down devices that are attached centrally to the floor, either diagonally or lengthways over the flat housing.

Figure 1 shows in plan in a schematic representation a splice holder according to the invention.

FIG. 2 shows the splice receptacle longitudinally in a side elevation the section line Il-tl.

The receptacle consists of a box-like _r shallow open-topped plastic housing with the side walls 1, the base 2 and the end faces 3 and 4. The end wall 4 is provided with through would break 5 can be introduced through the Liehtwellenleiterkabel 6 in the housing. The cables 6 are fixed by means of Blitzbinder 1, which are secured in recesses (not shown) in the housing. Shaped, inwardly protruding tab-like hold-down devices 8 protrude from the side walls 1 and form a cover over the light waveguides shown schematically in dashed lines. Rib-like wall portions 9 are also integrally formed on the housing base 2, the curved contact surfaces for the optical waveguides form * Also these ribs 9 are down device 10 formed * centrally at the bottom 2 11 is arranged a support member which supports a sheet-like forger holder 13 via a screw 12th Furthermore, a splice holder 14 is attached to the floor 2, in which the individual splice points are stored in an orderly, easily accessible and secure manner. The hold-down device 13 is covered in the area of the game holder 14 with a foam cushion 15 which covers the open compartments of the splice holder.

The support part 11 can be provided with a through hole, which allows the connection of a stack of housings enables. For stacking the housing, cams 16 are formed, which engage in corresponding corner parts of the open-topped housing. The support parts 11 can also be used for Can be used to fasten single or multiple housings to a carrier, e.g. using mounting brackets.
