Description

Optical fiber ribbon cable with foldable components Technical Field

[0001] The invention belongs to the field of optical cables, and in particular discloses an optical fiber ribbon cable with a foldable component. Background Art

[0002] CN210166542U discloses a zoned flat optical cable comprising a flame-retardant outer sheath, a non-metallic aramid reinforcement, a glass fiber reinforced core, and several optical fiber units. The optical fiber unit comprises a multi-core optical fiber ribbon. The non-metallic aramid reinforcement is filled between the optical fiber unit and the flame-retardant outer sheath. The optical fiber units are arranged side by side within the flame-retardant outer sheath, with an optical fiber unit spacer provided between each two optical fiber units. A pair of reinforcing ribs are provided on the inner wall of the outer sheath at the spacer, each of which contains a glass fiber reinforced core. This optical cable has a more ingenious and rational structure, making it less likely for the optical fiber ribbon to cross or become entangled when the cable is moved or bent, and also providing enhanced compression resistance. Technical issues

[0003] In the existing technology, outdoor optical cables are generally divided into layer-stranded type, central bundle tube type, and skeleton type. The layer-stranded optical cable is composed of multiple loose tubes containing optical fibers or optical fiber ribbons twisted around a central reinforcement to form a cable core, which is then covered with one or more protective layers. The loose tube needs to be wrapped with yarn to ensure the stability of the loose tube structure; the central bundle tube optical cable is formed by placing optical fibers or optical fiber ribbons in a loose tube, which is then covered with at least one protective layer; the skeleton optical cable is formed by placing optical fibers or optical fiber ribbons in a skeleton groove of a skeleton, and then covering the skeleton with at least one protective layer. In the prior art, layer-stranded optical cables require complex twisting equipment, which can damage the loose tube and the optical fibers or optical fiber ribbons inside during the twisting process. The binding yarn can also damage the loose tube. Due to the different expansion coefficients of the loose tube material and the binding yarn during temperature fluctuations, the loose tube can also be cracked or damaged. Center-tube optical cables require the entire loose tube to be stripped, but only a portion is actually needed for use, which can affect the unused portion. Skeleton-type optical cables have relatively large skeletons, so the fiber core density still needs to be improved. Furthermore, the production of the skeleton requires specialized skeleton manufacturing equipment, and the qualified rate of the rotating skeleton slots has always been relatively low.

Best Mode for Carrying Out the Invention

[0025] Implementation Example 1: See Figures 1 to 6, and refer to Figures 11 to 14. A fiber optic ribbon cable with a foldable component comprises a plurality of fiber optic ribbons 2 and an outer sheath 5. The fiber optic ribbon 2 is composed of a plurality of optical fibers 21 and an adhesive layer 22 covering the plurality of optical fibers 21. The invention is characterized in that: the optical fiber ribbon cable further comprises two identical foldable components 1, the foldable components 1 being composed of a first foldable segment 11, a second foldable segment 12, a third foldable segment 13, a fourth foldable segment 14, a fifth foldable segment 15, a sixth foldable segment 16, and a seventh foldable segment 17 connected in sequence. Folding grooves 10 are provided between adjacent foldable segments. When not bent, the lower surfaces of all the foldable segments are in the same plane, and the adjacent foldable segments can be bent. The folding grooves 10 between adjacent folding sections are bent relative to each other. The first folding section 11 has a first receiving hole 111, the second folding section 12 has a second receiving hole 112, the third folding section 13 has a third receiving hole 113, the fourth folding section 14 has a fourth receiving hole 114, the fifth folding section 15 has a fifth receiving hole 115, the sixth folding section 16 has a sixth receiving hole 116, and the seventh folding section 17 has a seventh receiving hole 117. Optical fiber ribbons 2 are contained in the first to seventh receiving holes. The lower surfaces of the fourth folding sections 14 of the two folding components 1 are tightly adhered to each other by adhesive, and the lower surfaces of the fifth folding sections 15 of the two folding components 1 are tightly adhered to each other by adhesive. In the first folding component 1 , the third folding segment 13 and the fourth folding segment 14 are bent at a right angle relative to each other, the second folding segment 12 and the third folding segment 13 are bent at a right angle relative to each other, the first folding segment 11 and the second folding segment 12 are bent at a right angle relative to each other, the sixth folding segment 16 and the fifth folding segment 15 are bent at a right angle relative to each other, and the seventh folding segment 17 and the sixth folding segment 16 are bent at a right angle relative to each other. After bending, the left end of the first folding segment 11 is located directly above the folding groove 10 between the fourth folding segment 14 and the fifth folding segment 15, and the right end of the seventh folding segment 17 is located to the right of the folding groove 10 between the first folding segment 11 and the second folding segment 12. The first folding segment 11, the second folding segment 12, the third folding segment 13, and the fourth folding segment 14 form a hollow first inner cavity 100, and the first folding segment 11, the fifth folding segment 15, the sixth folding segment 16, and the seventh folding segment 17 form a hollow second inner cavity 101.In the second folding component 1 , the third folding segment 13 and the fourth folding segment 14 are bent at a right angle relative to each other, the second folding segment 12 and the third folding segment 13 are bent at a right angle relative to each other, the first folding segment 11 and the second folding segment 12 are bent at a right angle relative to each other, the sixth folding segment 16 and the fifth folding segment 15 are bent at a right angle relative to each other, and the seventh folding segment 17 and the sixth folding segment 16 are bent at a right angle relative to each other.

The first folding segment 11, the second folding segment 12, the third folding segment 13, and the fourth folding segment 14 form a hollow third inner cavity 102, and the first folding segment 11, the fifth folding segment 15, the sixth folding segment 16, and the seventh folding segment 17 form a hollow fourth inner cavity 103. The two folded parts 1 form a cable core with a square cross section, and the outer sheath 5 covers the cable core.

[0026] The optical fiber ribbon cable with a foldable component described above is characterized by further comprising a plurality of optical fiber ribbons 4, each of which is composed of a plurality of optical fibers 41 and an adhesive sheath 42 covering the plurality of optical fibers 41. The plurality of optical fiber ribbons 4 are distributed in a stacked manner within the first inner cavity 100, the second inner cavity 101, the third inner cavity 102, and the fourth inner cavity 103.

[0027] The optical fiber ribbon cable with foldable components described above is characterized by having four power transmission components 3, each of which is composed of a conductor 31 and an insulating layer 32 covering the conductor. The four power transmission components 3 are respectively located in the first inner cavity 100, the second inner cavity 101, the third inner cavity 102, and the fourth inner cavity 103.

[0028] Furthermore, the optical fiber ribbon cable with foldable components described above is characterized in that at least one of the first inner cavity 100, the second inner cavity 101, the third inner cavity 102, and the fourth inner cavity 103 contains an optical fiber ribbon 4, and at least two of them contain a power transmission component 3. Modes for Carrying Out the Invention

[0029] Implementation Example 2: See Figures 7 to 10, and refer to Figures 1 to 6 and Figures 11 to 14. A fiber optic ribbon cable with a foldable component is basically the same as Implementation Example 1, except that: First, a protruding rib 18 is provided on the lower surface of the junction between the fourth folding segment 14 and the fifth folding segment 15. The rib 18 extends along the length direction of the folding component 1. The ribs 18 are intermittently distributed, with gaps 19 between adjacent ribs 18. The ribs 18 have rib holes 180 extending along the length direction of the folding component 1 and passing through the ribs 18. The length of the rib is L, the length of the gap is D, and the length of the rib is no greater than the length of the gap. Second, the lower surfaces of the fourth folding segments 14 of the two folding components 1 are not tightly attached to each other by adhesive, and the lower surfaces of the fifth folding segments 15 of the two folding components 1 are not tightly attached to each other by adhesive. The lower surfaces of the two folding components 1 are opposite, and the rib 18 of one folding component 1 is embedded in the gap 19 of the other folding component 1. The connecting component 6 passes through all the ridge holes 180 to fix the ridges 18 of the two folding components 1 .

[0030] Of course, this is not limited to the above situation. The lower surface of the left side of the fourth folding segment 14 may also have a ridge 18, a gap 19, and a ridge hole 180, and even the lower surface of the right side of the fifth folding segment 15 may also have a ridge 18, a gap 19, and a ridge hole 180, so that the two relatively buckled folding components 1 can be fixed more reliably and stably. It can also be that: the lower surface of the left side of the fourth folding segment 14 also has a ridge 18, a gap 19, and a ridge hole 180, and the lower surface of the right side of the fifth folding segment 15 also has a ridge 18, a gap 19, and a ridge hole 180, while the lower surface of the connection between the fourth folding segment 14 and the fifth folding segment 15 does not have a ridge 18, a gap 19, and a ridge hole 180.

[0031] Of course, the present application is not limited to the above-mentioned embodiments. In fact, in Implementation Example 1, there can also be only one folding component 1, but what is formed in this way is an optical fiber ribbon cable with a rectangular cross-section, and the fiber core density is slightly lower; while the cable core body in Implementation Examples 1 and 2 has a square cross-section, and the outer sheath also has a square cross-section, and the fiber core density is higher.

[0032] Of course, in the present application, in embodiment 1, the two folding parts 1 that are relatively buckled do not need to be glued together, because the outer sheath limits the position, and through bonding, a whole with more cavities is formed; of course, it is not limited to glue. In fact, other methods such as mutual locking, bonding coatings, etc. can be used, as long as the two are combined into one.

[0033] In the present application, the folding component 1 has an optical fiber ribbon inside, which further increases the fiber core density of the optical cable, and because it is located outside, it is more convenient and faster to remove.

[0034] In the present application, the cross-sections of the first inner cavity 100 , the second inner cavity 101 , the third inner cavity 102 , and the fourth inner cavity 103 are preferably square.

[0035] In the present application, when there is a transmission component, simultaneous optical and electrical transmission can be achieved in the same cable, saving costs such as procurement, maintenance, and laying. When there are two transmission components 3, single-phase power can be transmitted. When there are four transmission components 3, three-phase power can be transmitted, or used as a three-phase four-wire system. It can also be used as two-way single-phase power transmission, solving the problem of control cabinets and switches being located in outdoor houses, which requires additional power users to add trouble and expenses.

[0036] In the present application, the optical fiber ribbon in the inner cavity can be taken out or put in simply by peeling off the outer sheath and unbending the folded parts, so production, maintenance, and inspection are very convenient; at the same time, since the folded parts can be made of materials with higher strength and thinner thickness, the space occupancy rate of the optical fiber and the optical fiber in the entire optical cable is very high, that is, the fiber core density is high.

[0037] The optical fiber ribbon cable with a foldable component described above is characterized in that the foldable component 1 is an integrated structure.

[0038] The optical fiber ribbon cable with foldable components described above is characterized in that the material of the foldable component 1 is plastic, aluminum, copper, iron, steel or alloy.

[0039] The optical fiber ribbon cable with foldable components described above is characterized in that the type of the optical fiber 21 is G.652, G.653, G.654, G.655, G.656, G.657, A1a, A1b, A1c, or A1d.

[0040] The optical fiber ribbon cable with foldable components described above is characterized in that the material of the adhesive layer 22 is plastic, preferably polyacrylic resin.

[0041] The optical fiber ribbon cable with foldable components described above is characterized in that the conductor 31 is made of copper, aluminum or an alloy.

[0042] The optical fiber ribbon cable with foldable components described above is characterized in that the material of the insulating layer 32 is plastic.

[0043] The optical fiber ribbon cable with foldable components described above is characterized in that the type of the optical fiber 41 is G.652, G.653, G.654, G.655, G.656, G.657, A1a, A1b, A1c, or A1d.

[0044] The optical fiber ribbon cable with foldable components described above is characterized in that the material of the bonding sheath 42 is plastic, preferably polyacrylic resin.

[0045] The optical fiber ribbon cable with foldable components described above is characterized in that the outer sheath 5 is made of plastic.

[0046] In the present application, the outer sheath 5 can be extruded and coated on the cable core, or can be a soft plastic tube sheathed on the cable core.

[0047] The optical fiber ribbon cable with a foldable component is characterized in that the optical fiber ribbon in the receiving hole can be one layer or multiple layers, and when there are multiple layers, the optical fiber ribbon is distributed in a stacked manner.

[0048] The optical fiber ribbon cable with foldable components described above is characterized in that the optical fiber ribbon in the inner cavity can be one layer or multiple layers, and when there are multiple layers, they are distributed in a stacked manner.

[0049] The optical fiber ribbon cable in the present application is different from the layer-stranded optical cable in the prior art. It does not require expensive twisting equipment and yarn wrapping, thus overcoming the defects of the layer-stranded optical cable. At the same time, the optical fiber ribbons and optical fiber ribbons are dispersed and can be taken as needed, thus overcoming the defects of the central bundle tube optical cable. At the same time, since the size of the folding component is smaller than that of the skeleton optical cable, and the optical fiber ribbon can be easily taken out and placed by bending the folding component and the folding section, thus overcoming the defects of the skeleton optical cable.

[0050] Therefore, the present invention has the following major beneficial technical effects: simpler structure, more convenient manufacturing, fewer manufacturing equipment requirements, smaller site, higher fiber core density, and easier access to the optical fiber ribbon.

[0051] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions described in the claims, including equivalent alternatives to the technical features of the technical solutions described in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention. Industrial Applicability

[0052] The present invention has been implemented and has industrial applicability.
