Description
Technical Field
The application relates to the technical field of optical cables, in particular to an easy-to-maintain common optical cable assembly and a use method thereof.
Background
The optical cable consists of a reinforcing core, a cable core, a sheath, an outer protective layer and other parts, and also comprises a waterproof layer, a buffer layer, an insulated metal wire and other components according to requirements. The outer protective layer has two structures, namely a metal armor structure and a non-armor structure according to the requirements.
In the process of laying optical cables, various laying modes such as overhead, direct burial, pipeline, water bottom and the like are commonly adopted. The overhead optical cable can adopt the original overhead open line, has low construction cost and short construction period, is easily threatened by natural disasters such as typhoons, ice, floods and the like, is also easily influenced by external force, weakening of the mechanical strength of the overhead optical cable and the like, and has higher failure rate. Direct-buried optical cables are generally used with cables provided with an armor layer and an anti-corrosion outer jacket, buried directly in the ground, to resist external mechanical damage and to prevent soil corrosion. However, since the cable is buried underground and is not visible and there are few inspection, in recent years, the cable is dug out and broken. The conduit optical cable is usually arranged in urban areas and has conduit protection, so that the conduit optical cable has fewer faults, but has high cost and high requirements on the length of a laying section and the position of a connecting point. The submarine optical cable is arranged at the bottom of the water, and often needs to pass through complex hydrogeologic conditions such as rivers, lakes, beach banks, even oceans, and the like, so that the submarine optical cable has higher requirements on structural performance, and is extremely difficult to lay again and extremely high in cost after being damaged.
Because the optical cable is possibly damaged by environment or people under the conditions of transportation, construction and operation, once the optical cable outer sheath and even the steel-aluminum tape armor layer are damaged, the optical cable on the whole line can only be replaced, so that the waste of resources is caused, and the communication on the line is influenced. Especially for the direct-buried optical cable and the underwater optical cable, the cost of replacing the whole optical cable is even higher than the cost of laying one optical cable because the optical cable cost is high and the laying cost is high.
Disclosure of Invention
One of the purposes of the application is to provide an easy-to-repair common optical cable assembly, so as to overcome the defect of huge economic and manual loss caused by that the whole optical cable can only be replaced when the sheath layer and/or the armor layer on the surface of the optical cable are damaged in the prior art.

Detailed Description
For a better explanation of the present application, the main content of the present application is further elucidated with reference to the embodiments of the present application, and is further elucidated with reference to the specific examples, but the content of the present application is not limited to the following examples.
In the description of the present application, it should be understood that the terms "thickness," "upper," "lower," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, and are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

Thus, features defining "first," "second," etc. may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The following disclosure provides many different embodiments, or examples, for implementing different features of the application. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
In the prior art, once the sheath layer and/or the armor layer on the surface of the optical cable are damaged, the whole optical cable can be replaced, so that not only is the huge optical cable product wasted, but also the labor cost for replacing the optical cable is high, the time consumption is long, and the long-time communication interruption loss exists. Accordingly, in order to solve the technical problem that the sheath layer and/or the armor layer on the surface of the optical cable can only be replaced when the sheath layer and/or the armor layer are damaged in the prior art, the inventor proposes an easy-to-repair common optical cable assembly, as shown in fig. 2, which comprises:
the optical cable comprises a cable core and an outer layer structure which are sequentially arranged from inside to outside, wherein the outer layer structure comprises an armor layer and a sheath layer; the armor layer and/or the sheath layer are spliced by adopting a splicing belt which is detachably connected; and
and the repair piece is consistent with or complementary to the splicing tape structure.
It should be noted that, the optical cable provided in the present application may be a single-core optical cable or a multi-core optical cable, and is preferably a multi-core optical cable. The structure of the multi-core optical cable is a multi-core optical cable which is conventional in the prior art. Illustratively, as shown in fig. 1, the structure of the optical cable used includes, from inside to outside: a central reinforcing core 11, an optical fiber bundle passing through a plurality of optical fibers 12 including a loose tube 13 and disposed within the loose tube 13, an armor layer 15, and a sheath layer 16; a water-resistant layer and/or a heat-resistant layer can be arranged between the armor layer and the loose tube, and cable paste 14 with water resistance or heat resistance can be filled; a water-resistant layer and/or a heat-resistant layer can also be arranged between the sheath layer and the armor layer. The space between the optical fiber and the loose tube is filled with a filler material such as cable paste 14. The plurality of optical fiber bundles are wound on a central reinforcing core, and the central reinforcing core can be made of a high-strength metal material, an alloy material or a high-molecular polymer material and is used for providing support.
It should also be noted that the repair is identical to the structure of the splicing tape, and in the present application it should be understood that: when repairing the splice tape at the damaged position of the repair, the splice tape replaced at the repaired position is identical to the repair not only in geometry but also in distribution of the respective film layers. If the splice tape includes rectangular sheath layers and armor layers with the sheath layers being located outside of the armor layers, then the repair also includes rectangular sheath layers and armor layers with the sheath layers being located outside of the armor layers. While "the repair is complementary to the structure of the splicing tape" is understood in the present application to be: when the repair piece is used for repairing the splicing belt at the damaged position, the repair piece and the splicing belt close to the repaired position can be complementary in structure, if a bulge is arranged on the splicing belt close to the repair piece, a groove matched with the bulge is arranged at the corresponding position on the repair piece and used for being embedded with the bulge; the distribution of each film layer is required to be consistent with that of the adjacent splicing tapes, so that the closer the replaced and repaired optical cable is to the perfect optical cable, the better.
When the repairing piece comprises an armor repairing unit for repairing the armor layer and a sheath repairing unit for repairing the sheath layer, the repairing piece can be prepared by directly extruding and molding the sheath repairing unit on the surface of the armor repairing unit, and can also be obtained by bonding the prefabricated armor repairing unit and the sheath repairing unit. When the repair is obtained by bonding the armor repair unit and the sheath repair unit, the bonding material used is preferably the same bonding material as that of the sheath repair unit. If the sheath repairing unit is a polyethylene sheath splicing layer, the adopted bonding layer is also a polyethylene film. The armor repair unit and the sheath repair unit may be an armor splice tape and a sheath splice tape.
In some embodiments, the repair comprises a repair unit and an adhesive unit located on at least one side of the repair unit for adhering the repair unit and the optical cable, the repair unit being identical or complementary to the splice strap structure.
The bonding unit is used for connecting the repairing unit and the optical cable into a whole, and meanwhile, water vapor, impurities and the like in the environment are prevented from invading the inside of the optical cable from the repaired position. The material of the bonding unit is an organic bonding material which is easy to soften and melt at a lower temperature, such as 60-140 ℃, such as polyacrylic acid, polyethylene and the like; further preferably, the hydrophobic organic adhesive material, such as fluorine-containing polyacrylic acid, fluorine-containing polyethylene, etc., can better avoid intrusion of water vapor and impurities, especially water vapor, from the repaired site into the interior of the optical cable.
In some embodiments, the adhesive unit is disposed only outside of the repair unit. In other embodiments, the bonding units are arranged on the inner side and the outer side of the repairing unit, so that better bonding effect is formed, and meanwhile, stability and sealing performance are better.
In addition, if the material used for the sheath layer is an organic polymer material which is easier to soften and melt at a higher temperature, such as polyethylene or fluorine-containing polyethylene, the repair piece can be provided with no bonding unit, but the thickness of the repair piece is slightly higher than that of the spliced belt to be repaired, for example, the thickness of the repair piece is 0.05-0.08 m thicker than that of the spliced belt to be repaired, so that the repair piece is used for filling pores, and a better sealing effect is achieved. But the thickness difference is not too large to affect the sealing connection life between the repair and the cable due to stresses.
In some embodiments, the splice tape is a jacket layer splice tape; the repair parts comprise sheath layer repair units which are made of the same material as the sheath layer splicing tape, namely the corresponding repair parts comprise sheath layers and repair parts which do not comprise armor layers.
In other embodiments, the splice strap is an armored splice strap, and the repair includes an armored repair unit of the same material as the armored splice strap and a sheathed repair unit of the same material as the sheathed layer. The armor layer of the optical cable is usually formed by winding or braiding high-strength materials such as metal wires, has high strength and is difficult to cut. The sheath layer is often made of organic waterproof and anti-corrosion materials, so that the cutting difficulty is low, and the repair is convenient. Therefore, the armor layer is arranged to be of a splicing structure, the sheath layer is not arranged to be of a splicing structure, the repair of the armor layer is facilitated, and meanwhile, the waterproof and anti-corrosion performances of the optical cable are also facilitated to be maintained.
In other embodiments, the splice tape is a composite splice tape comprising an armor splice unit and a jacket splice unit connected as one; the repair comprises a composite repair unit of the same material as the composite splicing tape.
In some embodiments, the splice strap is a C-splice strap 21; and one C-shaped splicing 21 belt is connected end to form one section of outer layer structure. In this type of splicing tape, each splicing tape can form complete outer layer structure around cable core round by end to end connection, has reduced the quantity of splicing position of splicing tape, and is less to the intensity of optical cable and the effect influence of blocking water. And the adjacent splicing strips can be arranged on a straight line at the end-to-end connection position, and a water blocking film is arranged at the position to cover the splicing lines, so that the sealing effect is further improved.
In other embodiments, as shown in fig. 3 and 4, the splicing tape may be an arcuate splicing tape 22, with at least two arcuate splicing tapes 22 being joined to form a section of the outer layer structure.
In some embodiments, at least two end surfaces of the splicing tape are provided with a plurality of connection protrusions 221, and at least two other end surfaces are provided with a plurality of connection grooves 222 complementary to the connection protrusions 221 for splicing the splicing tape end to end and/or connecting adjacent splicing tapes.
The structure of the connecting protrusion can be various structures, such as various shapes of T-shaped, L-shaped, trapezoid, cone-shaped, spherical and the like. The corresponding structure of the connecting groove can be in various shapes such as a T-shaped groove, an L-shaped groove, a trapezoid groove, a conical groove, a spherical groove and the like correspondingly, so that the two are complementary.
In some embodiments, the connecting protrusion is an elastic connecting protrusion made of elastic materials, the size of the connecting protrusion is slightly larger than that of the connecting groove, interference fit of the connecting protrusion and the connecting groove is achieved, and sealing and stable connection of the connecting protrusion and the connecting groove are achieved through interference fit. In other embodiments, the surface of the connecting protrusion is provided with a connecting layer made of elastic material, the size of the connecting protrusion is slightly larger than that of the connecting groove, interference fit of the connecting protrusion and the connecting groove is achieved, and sealing and stable connection of the connecting protrusion and the connecting groove are achieved through interference fit.
Preferably, the connecting protrusion is a spherical protrusion, and the connecting groove is a spherical groove, so that the connecting grooves are mutually embedded, and meanwhile, the contact area is increased, so that the connecting strength and the sealing performance of the connecting protrusion and the connecting groove are better.
In some embodiments, the end surfaces of the splicing tapes are inclined surfaces so as to increase the contact area between the splicing tapes and the repair piece and improve the strength and sealing performance of the optical cable.
Specifically, in some embodiments, the end faces of the C-shaped splicing tapes are inclined planes inclined to the inner ring direction of the C-shaped splicing tapes, and the C-shaped splicing tapes are connected in parallel with the two side end faces of the adjacent C-shaped splicing tapes.
In other embodiments, the end faces of the arc-shaped splicing tape are inclined planes inclined to the inner ring direction of the arc-shaped splicing tape, and the two side faces of the arc-shaped splicing tape are parallel to each other.
The end faces of the splicing tape at the head and the tail refer to the faces of the end faces which are consistent with the direction of the axis of the optical cable; the side of the splice tape is the face on which the end face is located only perpendicular or nearly perpendicular to the axial direction of the optical cable.
The end faces of the C-shaped splicing belt or the arc-shaped splicing belt are inclined to the inner ring, so that deformation allowance is provided for stress difference of the C-shaped splicing belt or the arc-shaped splicing belt. Meanwhile, the inclination degree of the head end face and the tail end face of the C-shaped splicing belt or the arc-shaped splicing belt is not too large, for example, the included angle between the head end face and the tail end face of the C-shaped splicing belt and the surface of the outer ring is not smaller than 83 degrees, and is not larger than 87 degrees. It can be adjusted in this range depending on the material of the splice tape, the repair, etc. it is used. And the arrangement of the head end face and the tail end face of the repair piece is the same as that of the splicing belt.
The inclination angle of the two side surfaces of the splicing belt is not limited by the range, for example, the inclination angle of the two side surfaces of the splicing belt can be selected to be 30-70 degrees in a larger range.
In some embodiments, the armor is a metal plastic composite; the sheath layer is a polyethylene layer or a fluorinated polyolefin layer, preferably a fluorinated polyolefin layer, which has hydrophobicity and water resistance.
In some embodiments, the thickness of the armor layer is 0.15-0.25 mm; the sum of the thicknesses of the armor layer and the sheath layer is 0.25-0.35 mm; the difference between the thickness of the repair and the thickness of the repaired area is not more than 0.05mm, where the thickness of the repair should be higher than the thickness of the repaired area, but not lower than the thickness of the repaired area, that is to say the difference between the thickness of the repair and the thickness of the repaired area is not more than 0.05mm, it should be understood that the thickness of the repair is higher than the thickness of the repaired area by not more than 0.05mm.
