Abstract
The utility model relates to a fiber optical cable with a foaming filling element, comprising a foaming layer and a packaging layer coated around the foaming layer. The material of the foaming layer is high density polyethylene (HDPE) with foaming degree of 60-70 percent. The utility mode provides a fiber optical cable with a foaming filling element. Because the structure and the material of the existing filling element are changed, the production cost of the fiber optical cable is reduced and the production efficiency is improved.
Description
Technical field:
The utility model relates to a kind of optical cable, the optical cable of the foam filled element of particularly a kind of tool.
Background technology:
Along with the increase of each big mobile operator for optical fiber cable and cable amount of purchase, the development of line cable industry is more swift and violent.Traditional optical cable is the high density Insulation Material owing to the filling member material, and has following limitation:
1, cost of raw material height, line speed is unhappy, and efficient is not high;
2, the solid packing elements that adopts the high density Insulation Material to extrude is higher relatively owing to hardness, so in the stranded process with other twisting element (or loose sleeve pipe) when twisting altogether, easily with loose sleeve pipe crimp, thereby reduced the useful space of optical fiber, made reduce the useful life of optical fiber at Song Guanzhong.
The utility model content:
The purpose of this utility model is to provide a kind of optical cable that uses foam filled element, reduces the production cost of optical cable, enhances productivity.
The utility model is achieved in that
The optical cable of the foam filled element of a kind of tool is characterized in that: described optical cable comprises by foaming layer and is wrapped in foaming layer integument on every side and forms.
Further scheme is: the material of described foaming layer is the high density polyethylene (HDPE) of foam degrees 60～70%.
Further scheme is: the material of described integument is PBT or PP.
Further scheme is: the thickness of described integument is 0.05mm～0.15mm.
Further scheme is: the thickness of described integument is 0.1mm.
The foaming layer of the utility model optical cable has reduced production cost greatly owing to adopted foaming technique; And foaming layer packing elements softness, rounding, can not push other pine pipes; Outer dystectic PBT or the PP material of adopting, cable core that is twisted into and composite band can not bond, and guarantee can not break gasket for packing when stripping is held in construction, have improved the operating efficiency of construction simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further elaborated.
A kind of optical cable that uses foam filled element is that the physics foaming material of base resin is a base-material with the high density polyethylene (HDPE), and foam degrees is 60～70%, extrudes at a high speed and forms foaming layer 1; Squeeze simultaneously PBT (poly-to stupid dioctyl phthalate butanediol fat) or PP (polypropylene) integument 2 of a layer thickness 0.05mm～0.15mm foam filled element outside, cable core and vertical Baogang aluminium strip after avoiding gasket for packing stranded bond.
