Problems solved by technology

Most of the existing photoelectric composite cables adopt a loose-tube stranded structure. Due to the shackles of the yarn binding outside the cable core, it is very difficult to branch and connect the optical fibers from the cable in actual construction, and the existing loose-tube stranded cables generally It is a grease-filled structure, which brings great inconvenience to the connection, greatly affects the construction efficiency and increases the construction cost

Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] It includes an outer sheath 1, and a composite cable core is covered in the outer sheath. The cable core includes a skeleton 3, the skeleton is extruded from high-density polyethylene, and a central reinforcement 5 is arranged in the center of the skeleton. The central reinforcement mentioned above is a stranded steel wire rope; a skeleton groove with a circular radial cross-section is provided on both sides of the skeleton, the two skeleton grooves are symmetrical, and the circular skeleton groove is tangent (inscribed) to the outer periphery of the skeleton, and A skeleton slot opening is set at the tangent, and the opening width is 0.4-0.8mm larger than the outer diameter of an optical communication unit to prevent the optical communication unit in the slot from leaking out; an optical communication unit 4 is laid in the skeleton slot, and the o...

Abstract

The invention relates to a skeleton type photoelectric composite cable and a manufacturing method thereof. The skeleton type photoelectric composite cable comprises a skeleton and an outer sheath wrapping the skeleton. The skeleton type photoelectric composite cable is characterized in that two sides of the skeleton are respectively provided with a skeleton groove whose radial section is a circle or a large semicircle, optical communication units are arranged in the skeleton grooves in a laying manner, and power supply conducting wires are arranged at the upper side and the lower side of the skeleton. According to the cable, optical units and electric units are integrated so that wiring space resources are greatly saved, the construction cost is reduced, the structural setting is reasonable, the size is small, the optical cable is flexible and light, the optical communication units in the optical cable are easily separated and continued, the mechanical performance, the weather resistance, and the flexibility performance are excellent, and the optical cable can be applied to indoor and outdoor applications. The manufacturing method is simple and reasonable, the quality and the process are easily controlled, the production efficiency is high, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of optical fiber and cable, and in particular relates to a frame-type photoelectric composite cable and a manufacturing method thereof. Background technique [0002] As the construction speed of 4G network and smart grid PFTTH is getting faster and faster, for those places where it is inconvenient to get electricity, the photoelectric composite cable integrates the optical unit and the electrical unit, which solves the problem of power consumption of equipment in network construction, and because The integrated laying takes up little space, reduces the construction cost, and is easy to use. It has been widely used at present. Most of the existing photoelectric composite cables adopt a loose-tube stranded structure. Due to the shackles of the yarn binding outside the cable core, it is very difficult to branch and connect the optical fibers from the cable in actual construction, and the existing loose-tube str...
