Abstract
The utility model relates to a frame leading-in optical cable, which is characterized in that a round frame reinforced core with slots at the periphery is arranged in the cable core, wherein, a tight optical fiber unit comprising an optical fiber and a tight sleeve is inserted in the slot; a wrapping layer and a waterproof layer are arranged between the cable core and the outer protective layer of the cable in order. The utility model has the advantages of light weight, convenient construction, and high anti-lateral pressure intensity.
Description
Affiliated technical field
The utility model relates to a kind of leading in cable of communication network.
Background technology
Existing leading in cable structure is generally layer-twisted type or central beam tube type optical cable, and the external diameter of layer-stranding cable is bigger, Heavy Weight, construction inconvenience; Central beam tube type optical cable lateral pressure resistant intensity is lower, introduces the user because the bending of connecting up in the building is more, and optical cable is fragile.
Summary of the invention
In order to overcome the deficiency of existing leading in cable, the utility model provides a kind of skeleton leading in cable, it have weight light, be convenient to construction, lateral pressure resistant intensity advantage of higher.
Skeleton leading in cable provided by the utility model, comprise cable core (3) and outer jacket (10), cable core (3) contains the tight tube fiber unit of optical fiber (5) and tight sleeve pipe (6) composition thereof, the circular skeleton strengthening core (7) of peripheral groove (1) is set in the cable core (3), in the tight tube fiber unit embedded groove (1), in groove (1), place water-blocking material (4), between cable core (3) and outer jacket (10), coat wrapping layer (8), water barrier (9) successively.
To the utlity model has better lateral pressure resistant intensity in order making, reinforcement (2) can be set in the central authorities of skeleton strengthening core (7).
The beneficial effects of the utility model are to be convenient to construction as leading in cable, and are not fragile.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are the cross sectional representation of three embodiment of the present utility model, are respectively twin-core, four-core, the skeleton leading in cable of 20 four-cores.
Outer jacket in the drawings, 1, the groove on the skeleton strengthening core, 2, central reinforcement, 3, cable core, 4, water-blocking material, 5, optical fiber, 6, tight sleeve pipe, 7, skeleton strengthening core, 8, the wrapping layer, 9, water barrier, 10.
Embodiment
After adopting polythene material to extrude the skeleton strengthening core (7) that coats central reinforcement (2), in tight tube fiber unit embedded groove (1), coat the outer jacket (10) of wrapping up layer (8), water barrier (9) and making raw material with the low smoke and zero halogen material successively.
Claims (2)
1, a kind of skeleton leading in cable, comprise cable core and outer jacket, cable core contains the tight tube fiber unit of optical fiber and tight sleeve pipe composition thereof, it is characterized in that being provided with in the cable core the circular skeleton strengthening core of peripheral groove, in the tight tube fiber unit embedded groove, in groove, place water-blocking material, between cable core and outer jacket, coat wrapping layer, water barrier successively.
2, by the described skeleton leading in cable of claim 1, it is characterized in that reinforcement being set in the central authorities of skeleton strengthening core.
