Technical Field

[0001] The utility model belongs to the technical field of photoelectric cables, and particularly relates to an anti-interference photoelectric composite cable. Background Art

[0002] The optoelectronic composite cable is mainly composed of optical fiber, transmission copper wire and an external protective cover. The optical fiber realizes the transmission of optical signals, and the transmission copper wire realizes the transmission of electric power. With the mutual cooperation of optical fiber and transmission copper wire, the composite optical fiber can achieve the purpose of electrical and signal transmission.

[0003] At present, a Chinese utility model with publication number: CN219066479U discloses an anti-interference optoelectronic composite cable, including an aluminum foil shielding layer body, optical fiber components are arranged above and below the interior of the aluminum foil shielding layer body, the optical fiber component includes an optical fiber inner sheath, a ribbon optical fiber body is wrapped at the inner center of the optical fiber inner sheath, and non-metallic reinforcements are arranged inside the optical fiber inner sheaths on both sides of the ribbon optical fiber body; the inner core inner sheath can be used as a filling structure to isolate the outer sheath of the optical cable and the polyester tape, so that the internal and external structures of the composite optical cable are clear, the structural rationality is increased, the material cost in the manufacture of the composite optical cable is reduced, resources are protected, and it is beneficial to environmental protection. With the cooperation of various structures, the optical cable itself is non-flammable, combustion does not produce toxic gases, the shielding performance is good, the anti-interference ability is strong, and the signal transmission rate is high.

[0004] Since the existing optoelectronic composite cables are basically cylindrical in structure, the cylindrical structure on the surface is not resistant to extrusion and is easily deformed when a vehicle rolls over it from above. Therefore, a bracket is required to temporarily support the optoelectronic composite cable crossing the road surface, which is inconvenient for laying. At the same time, the surface of the cylindrical optoelectronic composite cable is very smooth, so during the laying process, if a vehicle passes by, the optoelectronic composite cable will move and the optoelectronic composite cable will be displaced, which makes it easy for workers to be disturbed when connecting the connector at the other end of the optoelectronic composite cable. For this reason, we propose an anti-interference optoelectronic composite cable. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-interference optoelectronic composite cable, which has the advantages of improving the ground gripping ability of the optoelectronic composite cable, reducing the interference of displacement on workers during wiring, improving the extrusion resistance of the optoelectronic composite cable, and reducing the risk of deformation.

[0007] By adopting the above technical scheme, the semicircular clamping block is pressed to tilt up to form teeth to grip the ground, thereby reducing the displacement of the optoelectronic composite cable; at the same time, pressing the end of the semicircular clamping block at the same position as the optoelectronic composite cable connector can also prevent the semicircular clamping block from being retracted into the groove due to the displacement thrust, thereby effectively improving the gripping ability of the optoelectronic composite cable and reducing the interference of the optoelectronic composite cable displacement on workers when wiring; when the optoelectronic composite cable is pulled, the semicircular clamping block is laid flat again, and the roller is used to rotate on the surface of the semicircular clamping block, thereby effectively reducing the pulling resistance of the optoelectronic composite cable and facilitating the dragging of the optoelectronic composite cable on the ground; by installing metal grids that are interlaced with each other inside the optoelectronic composite cable to form multiple triangular brackets, the stable, firm and pressure-resistant characteristics of the triangle are used to make the optoelectronic composite cable evenly distribute the pressure to both sides when it is run over by a vehicle, thereby improving the extrusion resistance of the optoelectronic composite cable, and finally, the triangular plastic strip can be used to support and buffer the distributed pressure to reduce the risk of deformation.

[0008] The utility model is further configured as follows: a groove is provided on the surface of the insulating jacket, the bottom of the inner cavity of the groove is a conical groove, a semicircular clamping block is rotatably connected inside the groove, and a roller is rotatably connected to the side of the semicircular clamping block away from the insulating jacket.

[0009] By adopting the above technical solution, the ground gripping ability of the optoelectronic composite cable is improved, and the interference of the displacement of the optoelectronic composite cable on workers during wiring is reduced; at the same time, the pulling resistance of the optoelectronic composite cable is reduced, making it easier to drag the optoelectronic composite cable on the ground.

[0010] The utility model is further configured as follows: the interior of the composite inner sleeve is respectively and entirely penetrated by electrical cables and optical cables which are fixedly connected thereto.

[0011] By adopting the above technical solution, the electrical cables and optical cables are installed in a row inside the composite inner sleeve, so that it is convenient for workers to distinguish and connect them and perform maintenance.

[0012] The utility model is further configured as follows: the interior of the composite inner sleeve is filled with a fireproof filler used in conjunction with electrical cables and optical cables.

[0013] By adopting the above technical solution, the fire resistance of the optoelectronic composite cable is improved and the risk of electrical and optical cables being burned is reduced.

[0014] The utility model is further configured as follows: the surface of the fireproof filler is covered with a shielding sleeve fixedly connected with the composite inner sleeve.

[0015] The above technical solution can effectively shield external signals and prevent electrical cables and optical cables from being interfered with.

[0016] The utility model is further configured as follows: a reinforcing rope used in conjunction with the electric cable and the optical cable is provided through the central part of the inner part of the composite inner sleeve.

[0017] By adopting the above technical solution, the strength of the optoelectronic composite cable is improved, and the installation of the optoelectronic composite cable is facilitated.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. Press the semicircular block to form teeth to grip the ground, thereby reducing the displacement of the optoelectronic composite cable; at the same time, press the end of the semicircular block that is at the same position as the optoelectronic composite cable connector to prevent the semicircular block from being retracted into the groove due to displacement thrust, thereby effectively improving the optoelectronic composite cable's grip on the ground and reducing the interference of the optoelectronic composite cable displacement on workers when wiring.

[0020] 2. When the photoelectric composite cable is pulled, the semicircular block is flattened again, and the roller is used to rotate on the surface of the semicircular block, so as to effectively reduce the pulling resistance of the photoelectric composite cable and facilitate the dragging of the photoelectric composite cable on the ground;

[0021] 3. By installing metal grids that are interlaced inside the optoelectronic composite cable to form multiple triangular brackets, the stable, firm and pressure-resistant characteristics of the triangle are utilized to evenly distribute the pressure to both sides when the optoelectronic composite cable is run over by a vehicle, thereby improving the extrusion resistance of the optoelectronic composite cable. Finally, the triangular plastic strips can be used to support and buffer the distributed pressure to reduce the risk of deformation. BRIEF DESCRIPTION OF THE DRAWINGS
