Description

Technical Field

[0001] This invention belongs to the technical field of communication optical cables, specifically relating to an easy-to-install, low-resistance miniature optoelectronic hybrid cable. Background Technology

[0002] Communication optical cables consist of a core made up of several optical fibers (generally ranging from a few cores to thousands of cores) and an outer sheath. Existing low-resistance micro-optical hybrid cables include optical fibers and an inner sheath outside the optical fibers. However, the separate laying of optical and electrical cables in existing low-resistance micro-optical hybrid cables is cumbersome and costly. The present invention provides a reinforcing member inside the inner sheath and a non-metallic reinforcing material wrapped around the outer side of the inner sheath. The reinforcing member and the non-metallic reinforcing material themselves have high tensile strength. The micro-optical hybrid cable includes a conductor, multiple optical fibers, multiple reinforcing members, and a sheath material covering the conductor, multiple optical fibers, and reinforcing members. The product has a simple structure and a reasonable distribution of conductors and optical fibers. This micro-optical hybrid cable has the advantages of small outer diameter, light weight, small space occupation, and low construction cost. By using metal reinforcing members and possible non-metallic reinforcing materials, it better meets the tensile strength requirements of the hybrid cable, has excellent bending performance and good lateral pressure resistance, and is easy to construct. By using low-resistance conductors, the improvements of the present invention can effectively solve the technical problems of cumbersome and costly separate laying of optical and electrical cables in the prior art.

[0003] The existing technology has the following problems: the existing low-resistance micro-optical hybrid cable has complicated and costly construction to lay the optical cable and electrical cable separately.

[0004] Content of this invention

[0005] The purpose of this invention is to provide an easy-to-install low-resistance miniature optical-electric hybrid cable to solve the problems mentioned in the background art, such as the cumbersome and costly construction of existing low-resistance miniature optical-electric hybrid cables where the optical cable and electrical cable are laid separately.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-install low-resistance micro-optical hybrid cable, comprising an optical fiber and an inner sheath on the outer side of the optical fiber; a reinforcing member is provided inside the inner sheath, and a non-metallic reinforcing material is wrapped around the outer side of the inner sheath, wherein the reinforcing member and the non-metallic reinforcing material themselves have high tensile strength.

[0007] The inner protective layer has a reinforcing member inside, and the outer side of the inner protective layer is wrapped with a non-metallic reinforcing material. The reinforcing member and the non-metallic reinforcing material themselves have high tensile strength.

[0008] Preferably, the non-metallic reinforcing material is internally encased with a low-resistance copper wire, and the copper wire purity of the low-resistance copper wire is greater than or equal to 99.95%.

[0009] Preferably, a water-blocking strip is provided on the outer side of the non-metallic reinforcing material, and the water-blocking strip is wrapped around the non-metallic reinforcing material to prevent water from entering.

[0010] Preferably, the water-blocking strip is wrapped with a metal composite strip on its outer side, and the metal composite strip itself has high toughness.

[0011] Preferably, the outer side of the metal composite strip is wrapped with a micro-optical hybrid cable outer sheath, which is made of rubber.

[0012] Preferably, the end of the metal composite strip is provided with a snap-fit ​​strip and a snap-fit ​​groove with the same outer diameter.

[0013] Preferably, the outer side of the metal composite strip is provided with a Velcro liner and the bottom surface is covered with a Velcro strip. The metal composite strip is formed by rolling the Velcro liner and the bottom surface covered with a Velcro strip.

[0014] Preferably, a small metal ball is disposed inside the snap-fit ​​strip, and the small metal ball is connected to the snap-fit ​​strip by a connecting spring.

[0015] Preferably, a rubber inner ring is provided on the outer side of the outer sheath of the micro-optical hybrid cable, an outer buckle is provided on the outer side of the rubber inner ring, a rubber embedded extrusion layer is provided at the lower end of the outer buckle, and a insertion cone with a threaded post is provided at the lower end of the rubber embedded extrusion layer. The insertion cone rotates and extrudes the rubber embedded extrusion layer to inflate the rubber inner ring, so that the outer buckle is fastened to the outer side of the outer sheath of the micro-optical hybrid cable.

[0016] Compared with the prior art, the present invention provides an easy-to-install, low-resistance miniature optical-electric hybrid cable, which has the following beneficial effects:

[0017] 1. In the low-resistance miniature optical-electric hybrid cable, the miniature optical-electric hybrid cable includes conductors, multiple optical fibers, and multiple reinforcing members, as well as a sheath material covering the conductors, multiple optical fibers, and reinforcing members. The product has a simple structure and a reasonable distribution of conductors and optical fibers. This miniature optical-electric hybrid cable has the advantages of small outer diameter, light weight, small space occupation, and low construction cost. It uses metal reinforcing members and possible non-metallic reinforcing materials to better meet the tensile performance of the hybrid cable, and has excellent bending performance and good lateral pressure resistance. It is easy to construct and uses low-resistance conductors. Through the improvement of this invention, the technical problem of separate laying of optical cables and electrical cables in the prior art, which is more complicated and costly, can be effectively solved.

[0018] 2. In low-resistance micro-optical hybrid cables, inspection usually requires peeling off the outer sheath. However, existing low-resistance micro-optical hybrid cables are typically one piece, making them difficult to separate. This invention addresses this by having the user insert a snap-fit ​​strip into the groove at the end of the outer sheath when wrapping it. A small metal ball, under the action of a connecting spring, will then press and snap it into a circular groove. The user can then flip the outer sheath to cover the Velcro patch, allowing the Velcro to adhere to the patch. To peel off the outer sheath, simply flip the outer sheath and pull. The addition of the outer sheath, Velcro patch, connecting spring, and small metal ball makes wrapping and peeling the outer sheath of the low-resistance micro-optical hybrid cable more convenient, faster, and with better sealing.

[0019] 3. In low-resistance micro-optical hybrid cables, the cable is prone to displacement and twisting when buried underground, which can easily damage its internal structure. This invention addresses this issue by providing a rubber inner ring on the outer side of the cable's outer sheath. An outer buckle is located on the outer side of this ring, and a rubber embedded compression layer is located at the lower end of the outer buckle. A threaded insertion cone is located at the lower end of this rubber embedded compression layer. The insertion cone rotates and compresses the rubber embedded compression layer, inflating the inner ring and causing the outer buckle to engage with the outer side of the cable's outer sheath. Workers insert the insertion cone, which rotates and connects to the outer buckle, into the ground. Because the inner ring is in contact with the cable, there is significant friction. The insertion cone helps to define the cable's placement, effectively preventing displacement and twisting during burial and thus avoiding internal damage. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides, for example Figure 1-4 As shown, an easy-to-install low-resistance miniature optical-electric hybrid cable includes an optical fiber 10 and an inner sheath 5 on the outside of the optical fiber 10. A reinforcing member 6 is disposed inside the inner sheath 5, and a non-metallic reinforcing material 14 is wrapped around the outside of the inner sheath 5. The reinforcing member 6 and the non-metallic reinforcing material 14 themselves have high tensile strength. The miniature optical-electric hybrid cable includes a conductor, multiple optical fibers 10, multiple reinforcing members, and a sheath material covering the conductor, multiple optical fibers 10, and reinforcing members. The product has a simple structure and a reasonable distribution of conductors and optical fibers 10. This miniature optical-electric hybrid cable has the advantages of small outer diameter, light weight, small space occupation, and low construction cost. The use of a metallic reinforcing member 6 and possibly a non-metallic reinforcing material 14 better meets the tensile strength requirements of the hybrid cable, providing superior bending performance and good lateral pressure resistance. Construction is convenient, and the use of low-resistance conductors effectively solves the technical problem of cumbersome and costly separate installation of optical cables and electrical cables in the prior art.

[0028] The non-metallic reinforcing material 14 is internally wrapped with a low-resistance copper wire 9. The copper wire purity of the low-resistance copper wire 9 is greater than or equal to 99.95%. The non-metallic reinforcing material 14 is externally wrapped with a water-blocking strip 7. The water-blocking strip 7 wraps around the non-metallic reinforcing material 14 to prevent water from entering. The water-blocking strip 7 can effectively prevent water from entering and affecting the internal use of the low-resistance micro-optical hybrid cable.

[0029] The outer side of the metal composite strip 8 is wrapped with a micro-optical hybrid cable outer sheath 1, which is made of rubber. The micro-optical hybrid cable outer sheath 1 can protect the low-resistance micro-optical hybrid cable and effectively prevent external friction and light exposure from reducing the service life of its internal materials.

[0030] The end of the metal composite strip 8 is provided with a snap-fit ​​strip 12 and a snap-fit ​​groove with the same outer diameter. The snap-fit ​​strip 12 is inserted in a simpler, faster and more fitting way.

[0031] The outer side of the metal composite strip 8 is provided with a Velcro 2 and an outer sheath 4 with a Velcro tab 3 on the bottom surface. The metal composite strip 8 is formed by rolling the Velcro 2 and the outer sheath 4 with the Velcro tab 3 on the bottom surface. The snap-fit ​​strip 12 is provided with a metal ball 11 inside, and the metal ball 11 is connected to the snap-fit ​​strip 12 by a connecting spring 13. Because it is usually necessary to peel off the outer sheath 1 of the micro-optical hybrid cable for inspection during normal processing, but the existing low-resistance micro-optical hybrid cables are usually one piece and difficult to separate. In this invention, when the user wraps the outer sheath 1 of the micro-optical hybrid cable, the snap-fit ​​strip 12 is inserted into the micro-optical hybrid cable. In the groove at the end of the outer sheath 1, the metal ball 11 is squeezed and snapped into the circular groove by the connecting spring 13. Then, the user flips the outer sheath 4 to cover the position of the Velcro 2. The Velcro 2 can stick to the Velcro 2. When it is necessary to peel off the outer sheath 1 of the micro-optical hybrid cable, simply flip the outer sheath 4 and pull it. By adding the outer sheath 4, the Velcro 2, the connecting spring 13 and the metal ball 11, the outer sheath 1 of the low-resistance micro-optical hybrid cable can be rolled up and peeled off more conveniently and quickly, and the sealing is relatively good.

[0032] like Figure 1 and Figure 5As shown, low-resistance micro-optical hybrid cables are prone to displacement and twisting when buried underground, easily leading to internal damage. To address this, the outer sheath 1 of the micro-optical hybrid cable of this invention has a rubber inner ring 15 on its outer side, an outer buckle 16 on its outer side, a rubber embedded extrusion layer 18 at the lower end of the outer buckle 16, and a threaded insertion cone 17 at the lower end of the rubber embedded extrusion layer 18. The insertion cone 17 rotates and compresses the rubber embedded extrusion layer 18, thus affecting the rubber... Inflation of the inner ring 15 allows the outer buckle 16 to fasten to the outer side of the outer sheath 1 of the micro-optical hybrid cable. Workers insert the insertion cone 17, which is rotatably connected to the outer buckle 16, into the ground. Because the rubber inner ring 15 is in contact with the low-resistance micro-optical hybrid cable, there is a large friction between them. The insertion cone 17 helps to limit the placement of the low-resistance micro-optical hybrid cable, effectively preventing the low-resistance micro-optical hybrid cable from shifting or twisting when it is buried underground, which would cause damage to the inside of the low-resistance micro-optical hybrid cable.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
