Description

The technical solution presented in this description relates to devices for installing and mounting optical fibers or optical cables in communication systems.

Known devices for installing and mounting optical fibers or optical cables in communication systems, each of which includes a base in the form of a plate, on the upper side of which are made fixing elements for fixing the splices of optical fibers from their movements in the vertical and horizontal planes, the fixing elements are made rectilinear, are perpendicular to the upper side of the base and form transverse rows of short locking elements located across the base and pepper rows of long locking elements; at the end of each long locking element, a conical head is made having beveled surfaces from the outside and shoulders from the lower side [1-6].

A significant factor in the operation of the device is the loading of the fixing elements from the action of the splice of optical fibers on them during the long-term operation of the device, since the fixing elements working under a bending load experience fatigue stress over time, which leads to a decrease in the fixing forces on the joints and reduces the reliability of fixing the joints in the device.

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

To this end, a device for removably securing elongated fiber-optic elements of communication lines comprises a panel, on the upper side of which there are alternating transverse rows of fixed rigid columns and transverse rows of flexible columns forming passages for accommodating interconnections of optical fibers of communication lines, each flexible column at the top has a hat and its width is less than the width of each rigid 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 on one end side of the aisle, at least one splice lock is made.

The height of each passage is greater than or equal to at least the heights of two splices stacked on top of each other in a tier.

Figure 1 shows a perspective view of a device for removable fastening of elongated fiber optic elements of communication lines; figure 2 is a fragment of the device; figure 3 - arrangement of splices of optical fibers between the hard columns of the device; figure 4 - arrangement of splices of optical fibers between the flexible columns of the device.

A device for removably securing elongated fiber-optic elements of communication lines contains a panel 1 (Fig. 1), on the upper side 2 of which there are alternating transverse rows 3 of fixed rigid columns 4 and transverse rows 5 of flexible flexible columns 6. These columns 4 and 6 form longitudinal passages 7 for placement of splices 8 (Figs. 3, 4) of optical fibers 9 of the communication lines in them. Each flexible column 6 at the top has a cap 10. The width S (FIG. 2) of each rigid column 4 is greater than the width S1 of each flexible column 6.

Rigid and flexible columns form a group of 11 (figure 1) columns in such a way that each column is located in its own group. Each group contains at least one row of 3 rigid columns 4 and one row 5 of flexible columns 6.

On the panel 1, at least on one end side 12, at least one latch 13 is made for fixing the splice 8 in the passage 7 from the longitudinal movements of the splice. The fixation of the latter by the latches 13 is carried out by pinching the splice 8 between adjacent latches.

The height H of each passage 7 (FIG. 3) is greater than or equal to the two heights H1 of at least two splices 8 stacked on top of each other in a tier.

Between each side surface 14 of the flexible column 6 (Fig. 4) facing the joint 8, and the surface of the joint 8, a gap t is formed. Each cap 10 (Fig. 4) of column 4 has upper beveled surfaces 15 and lower beveled surfaces 16.

Each flexible column 6 is located between two rigid columns 4 (figure 2) so that below they are made integral with the base 1 (figure 1) and on the side view, each group of 11 columns (figure 1) forms a W-shaped contour , which is the most optimal from the point of view of a strong connection of the columns with the base of the device. Between each rigid column 4 and adjacent flexible column 6 is a ledge 17 (figure 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), facing the splice 8, and the surface of the splice.

The device operates as follows.

By clicking on the splice 8 it is introduced into the passage 7 between the columns (Fig. 4), while the surface of the splice 8 slides along the beveled surfaces 15 of the flexible columns 4, the flexible columns bend in opposite directions in a vertical plane from the axis of the passage 7 and the splice 8 easily enters passage 7. If necessary, the second splice is installed on the first splice 8 as described above. When this splices occupy the position shown in figure 3 and 4.

When the device is operating, rigid columns 4 exclude the movement of each splice 8 in horizontal directions across the device, and flexible columns 6 exclude the movement of the splice in the vertical direction, and thanks to the gaps t formed between the surface of the splice and the surfaces 14 of the flexible columns 6, the latter are unloaded from the bursting bending columns 6 efforts. Obviously, these columns work only in tension in cases where upward forces are formed on the splice 8, which are insignificant during operation of the device.

As a result, this technical solution allows to significantly increase the strength of the device and the reliability of its operation during the long term of its operation in difficult conditions.
