Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a wear-resistant and bending-resistant optoelectronic composite cable. Background Art

[0002] Optical-electric composite cables are suitable for use as transmission lines in broadband access network systems. They represent a new access method, integrating optical fiber and copper transmission wire to address broadband access, device power consumption, and signal transmission. The diverse functions of optical-electric composite cables necessitate the complexity of their structure. However, a rational structural design can better fulfill and meet the cable's functional requirements, while also meeting manufacturing standards and reducing manufacturing costs, maximizing efficiency.

[0003] Existing optical fiber cables typically consist of a twisted-layer core and a sheath. This single-layer structure provides limited protection for the internal wires and optical fibers. During use, the outer layer is susceptible to wear and bending, which can damage the internal wiring and shorten the cable's service life. Therefore, a new type of optical fiber cable is needed that can effectively resist wear and bending, extending its service life and stability. Utility Model Content

[0007] The inner surface and outer surface of the outer cable sheath are respectively provided with an anti-bending sleeve and a wear-resistant sleeve, and the materials of the anti-bending sleeve and the wear-resistant sleeve are respectively polyethylene and glass fiber;

[0008] The composite assembly includes an optical fiber cable core located at the center of an inner cable sheath. The periphery of the optical fiber cable core is provided with a plurality of central reinforcement members distributed in a circular array, and each central reinforcement member is arranged in a hexagonal prism. Each central reinforcement member is fixedly connected between the optical fiber cable core and the inner cable sheath, and a transmission copper wire is installed between every two adjacent central reinforcement members.

[0009] Preferably, a grid-shaped protective layer is provided between the anti-bending sleeve and the middle cable sleeve, and the material of the grid-shaped protective layer is polyvinyl chloride.

[0010] Preferably, a corrugated protective layer is provided between the middle cable sheath and the inner cable sheath, and the material of the corrugated protective layer is fluororubber.

[0011] Preferably, the grid-like protective layer is composed of a plurality of plate sheets distributed in a circumferential array.

[0012] Preferably, the corrugated protective layer is composed of a plurality of corrugated sheets distributed in a circumferential array.

[0013] Compared with the existing technology, the advantages of the wear-resistant and bend-resistant optoelectronic composite cable provided by the present invention are:

[0014] 1. The anti-bending sleeve and wear-resistant sleeve made of polyethylene and glass fiber respectively can provide dual protection for the inner and outer layers of the outer cable sheath, and to a certain extent improve the wear resistance and anti-bending performance of the outer cable sheath;

[0015] 2. The staggered arrangement of the transmission copper wire, the central reinforcement and the transmission copper wire can effectively improve the connection strength between the inner cable sheath and the optical fiber core and the transmission copper wire, thereby further improving the wear resistance and bending resistance of the optical cable.
