Presented in this description of the technical solution relates to a device for installation of optical fibres or optical cables in communication systems.

The known device for the installation and mounting of optical fibers or optical cables in communication systems, each of which includes a base plate, on the upper side of which is made fixing elements for fixing splices of optical fibers from their movements in vertical and horizontal planes, the locking elements are made straight, are perpendicular to the upper side of the base and form a spaced across the base of the transverse rows of short clamping elements and transverse rows of long locking elements, at the end of each long locking element is made conical tip having outside beveled surface, and the bottom side - shouldered [1-6].

A significant factor in the operation of the device is loading the locking elements against splices of optical fibers during prolonged operation of the device as working under a bending load, the locking elements have time to fatigue stresses, which results in a decrease in retention efforts on splices and reduces reliable is here fixing splices in the device.

The technical result of this technical solution is to increase the reliability of the device and its service life.

For this purpose, the device for removable fastening of the elongated fiber optic elements of the communication lines contains a panel, on the upper side of which there are alternate transverse rows of stationary rigid columns and transverse rows of flexible columns, forming passages for placement of splices optical fiber communication lines, each flexible bar upstairs has a hat and a width less than the width of each of the hard column.

Rigid and flexible columns are arranged in groups, each of which contains at least one row of rigid columns and one row of flexible columns.

On the panel, at least one end side of the aisle made at least one latch of the cluster.

The height of each passage is greater than or equal to at least the height of two clusters, stacked on top of each tier.

Figure 1 presents a perspective view of a device for removable fastening of the elongated fiber optic elements of the communication lines; figure 2 is a fragment of the device; figure 3 - location of splices of optical fibers between the rigid bars of the device; figure 4 is a diagram of the locations of the splices of optical fibers between the flexible columns.

The mouth of austo for removable fastening of the elongated fiber optic elements of the communication lines contains a panel 1 (figure 1), on the upper side 2 of which are alternating transverse rows of 3 stationary rigid columns 4 and transverse rows 5 movable flexible bars 6. These columns 4 and 6 form longitudinal passages 7 for placement of clusters 8 (3, 4) optical fibers 9 lines. Each flexible column 6 above has the hat 10. The width of S (figure 2) of each of the hard column 4 is greater than the width S1 of each of the flexible column 6.

Rigid and flexible columns form a group 11 (figure 1) columns so that each column is in their group. Each group contains at least one row of columns 3 hard 4 and one row of 5 flexible columns 6.

On panel 1, at least one mechanical hand 12 is at least one retainer 13 for fixing the joint 8 in the passage 7 from the longitudinal movements of the joint. Fixing the last retainers 13 is carried out by crushing the joint 8 between adjacent tabs.

The height H of each passage 7 (Fig 3) is greater than or equal to two heights H1 of at least two clusters of 8, stacked on top of each tier.

Between each side surface 14 of the flexible column 6 (figure 4), addressed to the joint 8, and the surface of the joint 8 is formed a gap t. Each hat 10 (4) column 4 has an upper beveled surface 15 and a lower beveled surface 16.

Each flexible column 6 RA is placed between two rigid bars 4 (2) thus, below they made integral with the base 1 (Fig 1) and a side view each group 11 columns (1) to form a W-shaped contour, which is the most optimal from the point of view of the strong link bars with the base of the device. Between each rigid column 4 and related flexible column 6 is the ledge 17 (2), the depth of which is equal to the gap t (figure 4) between each side surface 14 of the flexible column 6 (figure 4), addressed to the joint 8, and the surface of the cluster.

The device operates as follows.

By clicking on a cluster of 8 it is introduced into the passage 7 between the bars (figure 4), while the surface of the cluster of 8 slides over the beveled surfaces 15 of the flexible columns 4, flexible columns bent in opposite directions in the vertical plane of the axis of the passage 7 and a cluster of 8 easily enters into the passage 7. Optionally, the first cluster of 8 establish described above, the second cluster. While the clusters occupy the positions shown in figure 3 and 4.

When the device is rigid bars 4 exclude move each cluster of 8 in a horizontal direction across the device and the flexible columns 6 exclude moving cluster in the vertical direction, and through the gap t is formed between the surface of the cluster and the surface 14 of the flexible columns 6, last unloaded from the schedule is non bending bars 6 effort. Obviously, these posts are only in tension if the splices 8 are formed upward-directed efforts, which are negligible at the device.

The result of this solution can significantly improve the durability of the device and the reliability of its work during the long period of its operation in difficult conditions.
