Abstract
The utility model belongs to the technical field of the optical cable technique and specifically relates to relate to self -supporting inside cable, this inside cable comprises plumb -line, oversheath, reinforcement, the tight jacket layer of optic fibre and optic fibre at least, the tight jacket layer of optic fibre parcel optic fibre, and the reinforcement is then wrapped up to the tight jacketed periphery of optic fibre, and the plumb -line distributes in the reinforcement outside, and fuse by the oversheath package is solid between plumb -line and the reinforcement, the tight jacket layer of oversheath and optic fibre all is fire -retardant sheaths. The utility model discloses not enough to current inside cable has provided a self -supporting inside cable, and the wholeness of product is good, and it has plumb -line and reinforcement to increase optic fibre outside, obtains splendid self -acceptance pull resistance from this, is difficult for receiving the exogenic action and the distortion that takes place to buckle, does benefit to house wiring use, increase of service life, simple structure, easy preparation, fiber cable jacket adopts fire -retardant sheath, increases performance.
Description
Technical field
The utility model relates to optical cable technology field, especially relates to a kind of inside cable.
Background technology
Along with the development of network technology, the demand of inside cable is increasing, its version is also more and more diversified, especially the structural shape of market abroad client to optical cable proposes much new requirement, but existing inside cable structural behaviour still exists and lacks self-supporting pull resistance, flame retardant effect is not good, is difficult to satisfied indoor use.The application proposes a kind of self-bearing type inside cable used for house wiring for this reason.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, has the self-bearing type inside cable of self-supporting pull resistance, be suitable for house wiring and use, and cable jacket adopts fire retardant jacket, increase usability.
For achieving the above object, the utility model adopts following technical scheme:
Self-bearing type inside cable, this inside cable is at least made up of messenger wire, oversheath, reinforcement, optical fiber tight sleeve layer and optical fiber, optical fiber tight sleeve layer parcel optical fiber, reinforcement is then wrapped up in the periphery of optical fiber tight sleeve layer, messenger wire is distributed in outside reinforcement, and consolidated by oversheath bag between messenger wire with reinforcement and be connected, oversheath and optical fiber tight sleeve layer are all fire retardant jackets.
Such scheme is further: described reinforcement is aramid yarn, is provided with one, two or multifiber in reinforcement.
Such scheme is further: described messenger wire adopts galvanized strand wires, phosphating steel wire or zinc-coated wire.
Such scheme is further: described optical fiber and optical fiber tight sleeve layer are arranged one to one.
Such scheme is further: described inside cable section is the figure of eight, and the spacer region of oversheath between messenger wire and reinforcement collects in flat connection.
The utility model is for the deficiency of existing inside cable, propose a kind of self-bearing type inside cable, the good integrity of product, increase outward at optical fiber and have messenger wire and reinforcement, obtain splendid self-supporting pull resistance thus, be not subject to External Force Acting and distortion occurs to bend, being beneficial to house wiring and using, increase the service life.
A utility model again advantage is that structure is simple, and easily make, cable jacket adopts fire retardant jacket, increases usability.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model preferred embodiment structural representation.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1, it is preferred embodiment schematic diagram of the present utility model, the utility model is about a kind of self-bearing type inside cable, this inside cable is by messenger wire 1, oversheath 2, reinforcement 3, optical fiber tight sleeve layer 4 and optical fiber 5 are formed, optical fiber tight sleeve layer 4 wraps up optical fiber 5, reinforcement 3 is then wrapped up in the periphery of optical fiber tight sleeve layer 4, messenger wire 1 is distributed in outside reinforcement 3, and wrap solid by oversheath 2 between messenger wire 1 with reinforcement 3 and be connected, messenger wire 1 and reinforcement 3 play tensile elements effect, realize the self-supporting pull resistance of inside cable thus, be not subject to External Force Acting and distortion occurs to bend, widen design and the use of inside cable, be beneficial to house wiring to use, increase the service life.Oversheath 2 of the present utility model and optical fiber tight sleeve layer 4 are all fire retardant jackets, and the flame-proof materials such as low-smoke halogen-free flame retardant material LSZH, fire retardant polyolefin material ZRPO, polyvinylchloride are made, and increase the usability of inside cable.
Shown in Fig. 1, the reinforcement 3 of the present embodiment preferably adopts aramid yarn, is provided with one, two or multifiber 5 in reinforcement 3, and optical fiber 5 and optical fiber tight sleeve layer 4 are arranged one to one, obtains ideal operation performance, and also convenient construction is implemented.Messenger wire 1 adopts galvanized strand wires, phosphating steel wire or zinc-coated wire, has enough pull resistances.Further, described inside cable section is the figure of eight, the spacer region of oversheath 2 between messenger wire 1 and reinforcement 3 to collect in flat connection 21, and flat connection 21 plays bridge connection function, obtains preferred construction, realize the self-supporting pull resistance of inside cable, be not subject to External Force Acting and distortion occurs to bend, widening design and the use of inside cable, being beneficial to house wiring and using, increase the service life, and also convenient construction is implemented.
Certainly; more than in conjunction with embodiment, the utility model is elaborated; only for technical conceive of the present utility model and feature are described; its object is to allow person skilled in the art understand content of the present utility model and to be implemented; therefore; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
