Technical field

[0001] The present invention belongs to the technical field of optical, cable, electric power and communication construction, and particularly relates to a cable or optical cable which is easily identifiable under both bright and dark conditions and a manufacturing method thereof.

Background technique

[0002] With the rapid development of the communication industry, the application of fiber optic cable, wire and cable is increasingly widespread. In the prior art, the application of cables in outdoor applications mainly includes: pipeline, buried, and overhead; Owners, but they may be laid on the same pipe and on the same pole. In this case, it brings great inconvenience to maintenance and maintenance personnel. Because the printing on the surface of the cable will gradually change with the change of the legs, therefore, maintenance It is extremely difficult for maintenance personnel to accurately find the cables to be maintained and repaired in the short time, especially at night or in extremely dark places. To this end, a lot of research has been done in this area in China, and the main documents are as follows.

[0003] CN202615012U discloses an anti-shooting night vision optical cable comprising a cable core 1 and an inner sheath 2 encasing the cable core 1, the cable core 1 comprising a fiber unit 3 and a reinforcing member 4 disposed around the fiber unit 3, The reinforcing member 4 is twisted into a compact circular shape around the optical fiber unit 3, and the optical fiber unit 3 includes an optical fiber 6 and a loose tube 5 encasing the optical fiber 6. The inner wall of the inner sheath 2 is continuously distributed. There is a notch 7 along the direction in which the cable extends, and the outer sheath 2 is also wrapped with an outer sheath 8 on the outer sheath 8, and a night light-emitting strip 9 is also disposed on the outer sheath 8.

[0004] CN105717596A discloses a self-supporting aerial cable which can be recognized by night vision, and is characterized in that it comprises: a cable core, an outer sheath covering the core, and a single steel wire or glass fiber reinforced plastic. a reinforcing element, a suspension sheath covering the reinforcing element, a rib connecting the suspension sheath and the outer sheath; the core is a centrally located central reinforcement, a plurality of loose sleeves outside the central reinforcement, and a package a protective layer covering the plurality of loose tubes; the loose tube has at least one optical fiber; the hanging sheath is symmetrically provided with two marking strips, the hanging material sheath, the outer sheath and the rib of the same material It is integrally formed; the marking strip is composed of the following raw materials by weight: low density polyethylene or medium density polyethylene or high density polyethylene or low smoke zero halogen flame retardant polyethylene 90 parts, polyethylene color masterbatch 2 Parts, 6 parts of titanium dioxide, 0.3 parts of antioxidant, 1.7 parts of natural paraffin. [0005] CN103048758A discloses a night vision cable; it comprises a cable core and a protective layer coated on the cable core

And an outer sheath extruded on the protective layer; the outer sheath is formed with at least one marking strip different in color from the outer sheath, and the marking strip is integrated with the outer sheath, in the optical cable In any cross section, the outer edge of the marking strip is on the same circumference as the outer edge of the outer sheath, the inner edge of the marking strip is an arc and its center is centered on the outer edge of the outer sheath and the inner edge of the outer sheath The center of the circle is coincident; the marking strip can emit light; the marking strip contains the following raw materials: 1 has the same main material as the outer sheath; 2 commercially available polyethylene masterbatch; 3 injection special luminous powder: 4 luminous enhanced addition powder. The invention has the beneficial effects of being easy to identify, convenient for construction, convenient for nighttime repair and maintenance, and can be clearly recognized at night.

[0006] In short, the above solution is to extrude an identification strip on a cable jacket. Of course, the identification strip may have the functions of luminous and bright light recognition. However, this method has the following main defects: (1) Multicolor is required The machine head, or a variety of molds, the same extrusion or injection molding, this method not only increases the investment of machinery and equipment, but also uses more venues, the combination of the marking strip and the sheath layer will also follow the daytime The change is small and the torsion resistance is relatively poor; (2) The management of various color strips and molds is troublesome, and different outer diameters require different color separation molds or jacket extrusion molds, resulting in an increase in cost.

[0007] CN204595274U discloses a communication light-emitting cable, which comprises a cable core, a protective layer covering the cable core, and an inner sheath extruded and coated on the outer layer of the protective layer. a central reinforcing member, which is distributed in a parallel or stranded manner, and is provided with a plurality of loose tube sleeves outside the reinforcing member, and a wrapping layer which is wrapped with a plurality of loose tubes, each of which has at least one optical fiber; The outer edge of the inner sheath has a plurality of grooves recessed toward the inner edge of the inner sheath, the groove has a light-emitting layer, the outer edge of the inner sheath has no groove, and the outer edge of the light-emitting layer is located. On the same cylindrical surface, the inner sheath and the outer layer of the light-emitting layer are extrusion-coated with a protective layer; the light-emitting layer is extruded and embedded in the groove together with the inner sheath; the protective layer is transparent. The luminescent layer is also extruded. The diameter of the cable or cable is different, and the extrusion dies of the inner sheath are different. Thus, the mold and thickness and width of the extruded luminescent layer are different.

[0008] The above methods all bring great trouble to the manufacturer.

[0009] On the other hand, most rare earth materials have the characteristics of light-emitting and light-emitting, and their elements have a special electronic layer structure. After the outer electrons are excited, the transition from the ground state to the excited state and then from the excited state to the ground state The energy is released in the form of light; therefore, most of the rare earth luminescent materials absorb only 5 points of visible light. The clock can continue to shine for more than 10 hours in the dark state, and can be recycled, non-toxic, harmless, non-radioactive, and has a life span of about 200 years.

In this way, the night vision unit can be embedded in the night vision aperture 55 through the slot 56. Not only is the material of the fourth portion 54 of the light-transmissive strip saved, but it is also more convenient to manufacture.

In the present invention, the night vision unit is extremely easy to replace, and the extrusion molding in the prior art cannot be replaced, and the related material can only be stripped and re-extruded. Therefore, the replacement of the invention is more convenient and more flexible.

[0064] In the embodiment and the current embodiment of the present invention, the most preferred manner is that the material of the fourth portion of the light-transmitting strip is dark, such as black, in this case, easier to identify; the preferred embodiment of the present invention The most preferred way is that the material of the sheath layer 3 is dark, such as black, in which case it is easier to identify.
