Description

The utility model relates to means for arranging cable sleeves for fiber-optic communication lines with a supply of fiber-optic cable (FOC) on pole supports, as well as on walls or other flat supporting surfaces of various structures, in particular on the supports of communication lines, lighting and power lines.

A device for winding a fiber optic cable (FOC) and a method of mounting a dead end coupling with interconnections of segments (ends) of a FOC on a support contact network of railways or a high-voltage power line (transmission line), RU 2189618 C1, 09/20/2002.

The invention relates to means for mounting couplings on supports for air suspension of fiber optic cable (FOC). The device for winding the wok contains a dead end sleeve located in a protective casing, made with the possibility of installation on a support. The reserve technological reserve of the wok is wound on a winding device made with the possibility of rigid fastening on a support or rotation on an axis made with the possibility of installation on a support. A winding device is used, made in the form of a frame supporting element, on the outer cylindrical surface of which U-shaped curved steel rods are placed for winding the reserve technological reserve of woks and to prevent the loss of turns of the reserve technological reserve of woks. The casing with the clutch and the winding device can be mounted on a support in mutually perpendicular planes. When installed on a support of the contact network of railways, a wok winder is installed along the railway track facing the railway track.

A device and method for aerial wiring of a wok on a high-voltage overhead line (US5696864A, December 9, 1997), in which a clutch with wok splices are installed in a protective casing and are mounted directly on the wire of a high-voltage power line.

The disadvantage of this solution is the low reliability due to the presence of windage, vibration and resonance phenomena during the "dance of wires" and the inconvenience of repair work.

A device is known for suspending couplings and cable stock, where the clutch and cable bay are fixed on one device (https://www.ssd.ru/ustroystvo-upmk-dlya-podveski-muft-i-zapasa-kabelya-universalnoe). The device is mounted on a support in three ways: using two clamps for fastening to pole supports; using two fastening tapes to pole supports; with the help of three tape clamps formed from pieces of mounting tape and locks-clamps. On the construction of steel corners (lattice support of power transmission lines, overpass, portal), the device is mounted using fastener sets to anchor supports. To mount the device at four points, two sets of fasteners are required. This device is made of steel, has a fairly large weight (8 kg) and dimensions.

A device for accommodating an optical coupling and a technological reserve of optical cable is intended for placement on the supports of urban electric facilities: street lighting, ground electric vehicles (Electrosetstroyproject product catalog "Linear fittings for optical cable. Protective equipment and standard design solutions", Issue No. 25, 2020 ., https://essp.ru/upload/files/link.pdf). The device can be fixed on any type of support using universal mounts. This device also has a fairly large weight (7.5 kg) and dimensions, which causes a large windage and, in turn, can be dangerous for the stability of the support on which it is installed.

The technical problem is the lack of reliability, as well as the large weight and dimensions of the known devices, as well as the expansion of the arsenal of technical means for installing a cable box and a supply of optical cable.

The technical result of the utility model is the implementation of the purpose of the bracket, as well as reducing the cost of manufacturing, reducing the weight and dimensions of the bracket.

The technical result is achieved by a bracket for installing a cable box and a supply of optical cable consisting of a housing having a flat rear wall and a crossbar mounted on the housing using fastening elements. The housing has L-shaped protrusions. On the rear wall of the housing there are means for attaching the bracket to pillar supports and flat surfaces. The crossbar has means for attaching the coupling to it, and the L-shaped protrusions have means for attaching them to the optical cable bay. The bracket is made of polymeric material.

In some versions of the bracket, the means of attachment to pillar supports and flat surfaces are holes that can be made paired and rectangular.

The fastening elements of the crossbar on the housing can be elongated racks with sockets that interact with locking screws, while elongated racks can be cylindrical.

Means for attaching the coupling to the crossbar can be holes for mounting screws, and means for attaching the bay of the optical cable to the L-shaped protrusions - holes for ties.

At least one cable stop may be arranged on the rear wall of the housing in the form of an arcuate wall.

The bracket for installing the cable box and the optical cable reserve (see Fig. 1) consists of a housing having a rear wall 1 in the form of a flat plate in a shape close to a circle segment and a crossbeam 2 connected to the housing by locking screws 3. The housing of the bracket has -shaped protrusions 4 and an external cable stop 5 located on the arched side of the housing. On the rear wall 1 there are made elongated elements 6 for fastening the crossbar 2 with sockets interacting with the locking screws 3. On the rear wall 1, closer to its center, there is also an internal cable stop 7 (see Fig. 3). The cable stops 5 and 7 are made in the form of walls at the same time with the rear wall 1.

Along the central axis of the plane of the rear wall 1, a pair of round holes 8 are made for fixing the bracket to the pillar supports with screws or anchors. Symmetrically to the central axis of the plane of the rear wall 1, there are two pairs of rectangular holes 9, designed to fix the bracket on the pillar support using steel or polymer tapes. In the peripheral part of the plane of the rear wall 1, several holes 10 are made for attachment to a wall or other flat surfaces using anchors, screws or other known means.

L-shaped protrusions 4 and cable stops 5 and 7 are designed for laying in the space between the optical cable coils (see FIG. 3), which is fixed on the L-shaped protrusions 4 by means of mounting clamps, ties or other known means of fastening (not shown) passing through holes 11 (see Fig. 3).

The crossbar 2 is designed for fastening to it couplings of various types, for which it has many holes 12 (Fig. 4). The crossbar 2 also has elongated grooves 13, which can be used to install additional devices. For installation on the fastening elements 6 at the ends of the crossbar 2, through cylindrical elements 14 are made, the inner diameter of which is mated to the outer diameter of the elements 6.

The operation of the device is illustrated by the example of installing a cable box and a supply of optical cable using two brackets mounted on a pole support one above the other, coaxial to its vertical axis of the support, while the curved sides of the upper and lower brackets face the upper and lower parts of the pole support, respectively.

The crossbars 2 are attached to the clutch housing 15 by means of fixing screws 16 (Fig. 5). From the side of the cable entries into the sleeve on the crossbar 2, a plate 17 can be fixed for fixing the cables. The coupling 15 with the crossbeams 2 attached to it is removably fixed to the fastening elements 6 by means of the locking screws 3 (Fig. 6).

Using steel or polymer tapes 18, which extend through rectangular openings 9, the brackets with a sleeve 15 mounted on them are fixed on the pillar support 19. Each bracket can be fastened with one or two tapes. Additional fixing of the brackets on the pillar support is carried out with screws, anchors or other similar fastening means through holes 8 and / or 10. Brackets can be mounted on supports or walls using other known methods (gluing, soldering, etc.).

For the installation of cables, the coupling 15 together with the crossbars 2 attached to it can be removed from the brackets, and at the end of the installation it is reinstalled on them.

The cable sheath 21 fits into the space bounded by the L-shaped protrusions 4 and the cable stops 5 and 7, and the ends of the cables 22 included in the sleeve can be fixed on the plate 17 with clamps 20, which can be used as worm clamps, ties or other similar means of fastening.

Instead of the sleeve 15, a template 23 may be used to pre-install the brackets on the pillar support or wall, the location of the mounting holes for which is similar to the sleeve (FIG. 15).

On the L-shaped protrusions 4, the cable bay 21 is fixed with ties 24 (Fig. 7). To maintain the coupling 15 during operation, it must be removed from the brackets together with the attached crossbars 2. To release the crossbar 2 from the fastening elements 6, it is necessary to turn the locking screws 3 around their axis and remove the coupling 15 together with the crossbars 2 and screws 3.

The bracket is made of polymeric materials, resulting in a reduction in manufacturing costs, reduction in weight and dimensions of the bracket, simplified transportation to the installation site and the complexity of installation. The brackets provide a compact placement of the cable box and the supply of optical cable and their reliable installation on pole supports, which reduces the windage of the entire structure and in turn has a positive effect on the reliability of the device as a whole.

Fastening of brackets to pillar supports is possible with the help of clamps and fastening tapes to pillar supports. Fastening the bracket to flat surfaces is possible using anchors, dowels, screws, screws or other known means.

The design of the bracket ensures the fastening of the coupling, the placement of stock of optical cable, as well as the installation and fastening of additional devices, such as clamps for fixing cables.
