Abstract
An outdoor optical cable for communication containing a foaming filling rope comprises a cable core, an aluminum-plastic or steel-plastic composite belt and an outer sheath, wherein the outer sheath is wrapped by the cable core; the packing rope has low material density and light weight, so that the weight of the optical cable is reduced, and the transportation cost can be reduced.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially contains the communication outdoor optical cable of foaming packing gasket.
Background technology
Existing communication generally adopts high density polyethylene to make with the gasket for packing in its cable core of outdoor optical cable, because hardness is higher, the extruding force that is subjected in machine when making cable core with the common strand of other element (as the loose sleeve pipe of optical fiber) is bigger, limited high-speed production, and easily make other deformed element cause the cable core distortion, influence the roundness of optical cable; Because the density of material height of gasket for packing is heavier, the weight of optical cable is increased, transportation cost improves.
Summary of the invention
In order to overcome the deficiency of existing communication with outdoor optical cable, the utility model provides the communication that contains foaming packing gasket outdoor optical cable, the speed of production height, and roundness is good, and weight is lighter, and transportation cost is low.
A kind of communication outdoor optical cable that contains foaming packing gasket that the utility model provides comprises cable core and oversheath thereof, has optical fiber and loose sleeve pipe thereof, central reinforce member, gasket for packing in the cable core, and the rope body of gasket for packing is a foam polyethylene.
The another kind that the utility model provides contains the communication outdoor optical cable of foaming packing gasket, comprises cable core and oversheath thereof, has optical fiber and loose sleeve pipe thereof, central reinforce member, gasket for packing in the cable core, and the rope body of gasket for packing is made of the sheath of foam polyethylene and outsourcing.
For improving intensity of the present utility model, strengthen shielding properties, between the cable core of above-mentioned two kinds of optical cables and oversheath, be equipped with plastic-aluminum or composite steel-plastic belt.
The beneficial effects of the utility model are: because the rope body of the gasket for packing that is provided with in cable core is foam polyethylene or is made of the sheath of foam polyethylene and outsourcing, softer, in that to twist the extruding force that is subjected in machine when making cable core altogether less with other element, can high-speed production, and can not make other deformed element cause the cable core distortion, not influence the roundness of optical cable; Because the density of material of gasket for packing is low, low weight, and the weight of optical cable is reduced, and can reduce transportation cost.
Description of drawings
Fig. 1, Fig. 2 are respectively the cross sectional representation that the utility model contains two kinds of different structure gasket for packings.
In Fig. 1, Fig. 2,1, the foam polyethylene of gasket for packing, 2., optical fiber, 3, fine cream, 4, loose sleeve pipe, 5, plastic-aluminum or composite steel-plastic belt, 6, central reinforce member, 7, the cable cream that blocks water, 8, cable core, 9, oversheath, 10, the sheath of gasket for packing.
Embodiment
With reference to Fig. 1, make gasket for packing (being foam polyethylene 1) earlier: the high density polyethylene base resin with 98～99% is a base-material, and the nucleator that adds 1-2% mixes back fusion refining and is one, extrudes at a high speed under 165-185 ℃ of temperature, form foam polyethylene 1, foam degrees is 10-80%.Then gasket for packing is included loose sleeve pipe 4, the central reinforce member 6 of optical fiber 2 and fine cream 3, the cable cream 7 stranded cable cores 8 of making that block water with several, outside cable core 8, coat plastic-aluminum or composite steel-plastic belt 5 and oversheath 9 more successively, promptly make a kind of the utility model.
With reference to Fig. 2, make gasket for packing (the promptly outer foam polyethylene 1 that is surrounded by sheath 10) earlier: the high density polyethylene base resin with 98～99% is a base-material, the nucleator that adds 1-2% mixes back fusion refining and is one, under 165-185 ℃ of temperature, extrude at a high speed, form foam polyethylene 1, foam degrees is 10-80%, outside foam polyethylene 1, adopt again to gather benzene fourth dioctyl phthalate butanediol ester or tygon coating sheath 10. are included the loose sleeve pipe 4 of optical fiber 2 and fine cream 3 with gasket for packing and several then, central reinforce member 6, the stranded together cable core 8 of making of the cable cream 7 that blocks water, outside cable core 8, coat plastic-aluminum or composite steel-plastic belt 5 and oversheath 9 more successively, promptly make another kind of the utility model.
Claims (4)
1. a communication outdoor optical cable that contains foaming packing gasket comprises cable core and oversheath thereof, has optical fiber and loose sleeve pipe thereof, central reinforce member, gasket for packing in the cable core, and the rope body that it is characterized in that gasket for packing is a foam polyethylene.
2. by the described a kind of communication outdoor optical cable that contains foaming packing gasket of claim 1, it is characterized in that between cable core and oversheath, being provided with plastic-aluminum or composite steel-plastic belt.
3. a communication outdoor optical cable that contains foaming packing gasket comprises cable core and oversheath thereof, has optical fiber and loose sleeve pipe thereof, central reinforce member, gasket for packing in the cable core, and the rope body that it is characterized in that gasket for packing is made of the sheath of foam polyethylene and outsourcing.
4. by the described a kind of communication outdoor optical cable that contains foaming packing gasket of claim 3, it is characterized in that between cable core and oversheath, being provided with plastic-aluminum or composite steel-plastic belt.
