Abstract
The present case is an optical cable from band stop water function, includes: the oversheath, it is outermost water blocking layer, the nonmetal strengthening band that blocks water, it is located the oversheath inner circle, fiber core, it comprises the multifiber, PBT loose tube will the mode of fiber core parcel is located its skin, the fine cream that blocks water, it is filled and is in in the PBT loose tube. The harm that various factorss such as sewage led to the fact the optical cable can drawn and prevent to the optical cable of present case effectively, has guaranteed the life of optical cable, can absorb with the influence that stops most external mechanical forces and environmental factor optic fibre in to the optical cable, therefore have outdoor optical cable advantage.
Description
Technical field
The utility model relates to optical cable, particularly relates to a kind of optical cable carrying water stop function.
Background technology
The technology that usual outdoor filled type communications optical cable is identical, only in the difference of filling cable cream part, ointment pump or other factice for filling parts can not be used, spraying cable cream device is installed, be sprayed on steel, aluminium strip by special for spraying cable cream before steel, aluminium strip enter preforming tool, each rice sprays half meter of cable cream; If alone spraying can not play block-water effect, can use before spraying and fill cable cream, and use vulcanite scraper cream mould all to be struck off by cable cream all around cable core, only stay the cable cream at the stranded place of cable core, re-use spraying afterwards.Purposes due to inside cable determine the resistance to tension of optical cable poor, there is no stop water yet, be not suitable for laying use in pipeline, may there is sewage and mouse etc. in pipeline, cable lifetime is in the presence of a harsh environment seriously affected by environment simultaneously.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure simply to carry the optical cable of water stop function.
For achieving the above object, the utility model is achieved through the following technical solutions:
Carry an optical cable for water stop function, comprising:
Oversheath 1, it is outermost water blocking layer;
The nonmetal reinforcing band 2 that blocks water, it is positioned at described oversheath inner ring;
Fiber cores 5, it is made up of multifiber;
PBT pine pipe box 3, is positioned at by the mode that described fiber cores is wrapped up in its skin;
Block water fine cream 4, and it is filled in described PBT pine pipe box.
Preferably, the described optical cable carrying water stop function, wherein, described oversheath is medium density polyethylene, i.e. MDPE water blocking layer.
Preferably, the described optical cable carrying water stop function, wherein, described fiber cores is made up of 12 to 144 optical fiber.
Preferably, the described optical cable carrying water stop function, wherein, described PBT pine pipe box material is polybutylene terephthalate.
Preferably, the described optical cable carrying water stop function, wherein, the described nonmetal reinforcing band component that blocks water is some nonmetal wire rods, for the Hot melt adhesive tape of coated described nonmetal wire rod, heat curing for bonding the adhesive of nonmetal wire rod and described Hot melt adhesive tape between described nonmetal wire rod and Hot melt adhesive tape, the outside surface of described Hot melt adhesive tape is also coated with the expanding powder of one deck for the waterproof that absorbs water.
The beneficial effects of the utility model: the utility model structure is simple, adopt the nonmetal reinforcing band that blocks water, its component is some nonmetal wire rods, for the Hot melt adhesive tape of coated nonmetal wire rod, heat curing between nonmetal wire rod and Hot melt adhesive tape for bonding the adhesive of nonmetal wire rod and Hot melt adhesive tape, the outside surface of Hot melt adhesive tape is also coated with the expanding powder of one deck for the waterproof that absorbs water, effectively draw and prevent the infringement that the various factors such as sewage cause optical cable, ensure that the serviceable life of optical cable, the structure Absorbable rod of this case and stop most of external mechanical power and environmental factor on the impact of optical cable inner fiber, thus there is outdoor optical cable advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation carrying the optical cable of water stop function described in the utility model one embodiment.
Wherein, 1-oversheath, the nonmetal reinforcing band that blocks water of 2-, 3-PBT pine pipe box, 4-blocks water fine cream, 5-fiber cores.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
Carry an optical cable for water stop function, refer to accompanying drawing 1, comprising:
Oversheath 1, it is outermost water blocking layer;
The nonmetal reinforcing band 2 that blocks water, it is positioned at described oversheath inner ring;
Fiber cores 5, it is made up of multifiber;
PBT pine pipe box 3, is positioned at by the mode that described fiber cores is wrapped up in its skin;
Block water fine cream 4, and it is filled in described PBT pine pipe box.
Further, described oversheath is medium density polyethylene, i.e. MDPE water blocking layer.
Further, described fiber cores is made up of 12 to 144 optical fiber.
Further, described PBT pine pipe box material is polybutylene terephthalate.
Further, the described nonmetal reinforcing band component that blocks water is some nonmetal wire rods, for the Hot melt adhesive tape of coated described nonmetal wire rod, heat curing for bonding the adhesive of nonmetal wire rod and described Hot melt adhesive tape between described nonmetal wire rod and Hot melt adhesive tape, the outside surface of described Hot melt adhesive tape is also coated with the expanding powder of one deck for the waterproof that absorbs water.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
