Abstract

The container 1 for housing the excess length of cables or ribbons 8 of optical fibre type comprises support blocks 7, 13 for the cables, which support blocks are provided with through openings 9, 11 (14, 14A) with slits 10 (15), the thickness of which slits makes it possible for the ribbons (8) to be slid transversely into the openings. The ribbons are retained by the blocks in an ellipsoidal path inside the container. <IMAGE>

Description

"CONTAINER FOR HOUSING THE EXUBERANT PORTIONS (EXCESS LENGTHS) OF CABLES, IN PARTICULAR OF CABLES OF OPTICAL FIBRE TYPE The present finding is concerned with a container for housing the exuberant portions (excess lengths) of cables, in particular of optical fibre cable type.
In the field of the transmission of signals via cable and the field of telephony in general, the use of "ribbons" containing a plurality of optical fibres is known.
Inasmuch as when the cables are laid, each ribbon has to be joined with the successive one, in the juncture region a portion of cable of superabundant length has to be provided in order to make it possible further operations to be carried out besides the joining operation, such as the lapping operation to which the ribbon ends have to be submitted before being joined.
Such ribbon portions of superabundant length, also said "excess length" of the ribbon, have to be arranged in a suitably ordered fashion and housed inside the interior of a container.
For that purpose, the present invention proposes a container for housing the exuberant portions (excess lengths) of cables in ribbon form, in particular of ribbon cables of optical fibre type, comprising a box body bounded by walls, with at least one of said walls being provided with means for supporting in an ordered way the ribbons and with at least one opening through which the ribbons entering into, and exiting from, the box body, run, characterized in that the ribbon support means comprise a plurality of blocks arranged along a substantially ellipsoidal trajectory with through openings with slits, the thickness of which slits equates the thickness of the ribbons.
The instant finding is illustrated for merely exemplifying, non-limitative purposes in the figures of the hereto attached drawing tables, wherein: Figure 1 shows a plan view of the container; Figure 2 shows a partial sectional view according to the path line II-II of Figure 1; Figure 3 shows a partial sectional vier according to the path line III-III of Figure 1; Figure 4 shows a sectional view according to the path line IV-IV of Figure 1; in said figure, the groups of ribbons, of rectangular cross-section, are represented by means of the simple indication of the overall dimensions of the whole group.
Referring to the above figures, the container for housing the exuberant portions (i.e., the excess lengths) of cables of optical fibre type, generally indicated with the reference numeral 1, comprises a box body (e.g., a parallelepipedal shaped body), inside which means for supporting the ribbons are installed.
The box body 2 is provided with a bottom wall or surface 3, an openable wall opposite to the bottom wall 4, a first pair of mutually opposite side walls 5 and a second pair of mutually opposite side walls 6.
The side walls of the second pair of walls 6 have a larger surface-area than the first pair of walls 5.
The ribbon support means comprise a set of first support blocks 7 grouped, in the herein exemplified case, in a first pair of support means, a second pair of support means and a third pair of support means, all fastened onto the bottom wall 3. The first pair and the second pair of first support blocks 7 are identical to each other, and each pair of said first support blocks are respectively close to one of the two side walls of the second pair of side walls 6.
On the contrary, each first block 7 of the third pair of blocks is close to one of the two side walls of the first pair of side walls 5. In the overall, the first support blocks 7 are arranged along a trajectory of substantially ellipsoidal shape, so as to give the same shape to the exuberant portion (i.e., the excess length) of each ribbon 8. The first blocks 7 of the first pair of blocks and of the second pair of blocks are each provided with a plurality of first through openings with circular section 9 provied with first slits 10, the thickness of which equates the thickness of the ribbons 8.
The third pair of first blocks 7 are provided with through openings of rectangular section 11, the shorter sides of which are rounded. Also said rectanguLar openings are provided with first slits 10.
Through at least one of the side walls 6 of the second pair of side walls, a rectangular opening 12 is provided, through which the ribbons 8 entering in, and exiting from, the interior of the box body run.
At the rectangular opening 12 a second support block 13 is provided, which is provided with a second through opening 14 and a third through opening 14A. Both of said through openings are provided with second slits 15.
The openable wall 4 opposite to the bottom wall can be removed from the box body 2 by being slid outwards along sliding guides 16 provided on each one of the side walls of the second pair of side walls 6.
The wall 4 is made from a transparent material, so as to make it possible the ribbons 8 and the relevant junctures to be seen from the outside.
Operatively, the end lengths of the ribbons 8 are introduced through the side rectangular opening(s) 12.
Once that the juncture is accomplished, the ribbons are inserted through the first slits 10 of the openings 9 and 11 of the first support blocks 7, so as to define an ellipsoidal trajectory of the excess length of the ribbons. The ribbons 8 are subsequently slid through the second slits 15 into the interior of the second through opening 14 and of the third through opening 14A.
The ribbons 8, which are of rectangular section, arrange themselves with their larger sides perpendicular to the second slits 10 and to the second slits 15, consequently remaining constrained inside the openings 9 and 12.
The position of the rectangular openings 12 in the central region of the side walls 6 of the second pair of side walls makes it possible the curved portions of the ribbons 8 running in correspondence of the first pair of side surfaces 5 to be completely sheltered. Thanks to the large value of the internal volume of the box body 2, the ribbons 8, as they are joined, can be easily arranged in their correct position, and the same ribbons 8 can be easily identified when subsequent intervention have to be carried out later on.
