Abstract
The utility model discloses a novel road trough optical cable. The novel road trough optical cable comprises an optical fiber unit, an outer sheath (6) and a plurality of metal reinforcing pieces A (8), wherein the optical fiber unit is arranged at the center of the optical cable, the outer sheath (6) is coated on the outer side of the optical fiber unit, and the plurality of metal reinforcing pieces A (8) are respectively arranged at symmetrical positions at two sides inside the outer sheath; the optical fiber unit comprises water resisting rings (2), a loose tube (3), a waterproof filling material (4), optical fibers (5), the outer sheath (6) and a metal band (7), wherein the waterproof filling material (4) is arranged between the optical fibers (5) and the loose tube (3), a plurality of water resisting rings are arranged between the loose tube (3) and the metal band (7), and the outer sheath (6) is coated on the periphery of the metal band (7). The novel road trough optical cable of the utility model is advantageous in enhanced pressure resistance and prolonged service life; and with the water resisting rings (2) adopted, the novel road trough optical cable is further advantageous in favorable water resisting property, reduced weight and decreased optical cable production cost.
Description
Technical field
The utility model relates to a kind of Novel road groove optical cable.
Background technology
Being laid at present road Cao Nei road groove optical cable under road surface is circular configuration, and this structure makes road groove optical cable stressed concentrated, easily by broken, is changed, and has a strong impact on serviceable life.Existing road groove optical cable generally plays by the mode of waterstop the effect blocked water in the periphery of loose sleeve pipe, adopts the form of waterstop to waste material, makes the production cost of producer higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Novel road groove optical cable is provided, optical cable in the groove of road stressed evenly, strengthen the optical cable resistance to pressure; Improve the optical cable water-blocking performance, and alleviate the weight of optical cable, reduce the optical cable production cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel road groove optical cable, it comprises fiber unit, oversheath and a plurality of metal reinforcement A, fiber unit is arranged at the center of optical cable, oversheath is coated on the fiber unit outside, and a plurality of metal reinforcement A are arranged at respectively symmetria bilateralis position in oversheath; Described fiber unit comprises water-ring, loose sleeve pipe, waterproof filling material, optical fiber, oversheath and metal tape, be provided with the waterproof filling material between optical fiber and loose sleeve pipe, be provided with a plurality of water-rings between pine sleeve pipe and metal tape, oversheath is coated on the periphery of metal tape.
Fiber unit described in the utility model also comprises a metal reinforcement B, and metal reinforcement B is arranged at the center of fiber unit.
Oversheath described in the utility model is pancake.
The beneficial effects of the utility model are:
1) oversheath of optical cable is designed to platypelloid type, and is equipped with metal reinforcement in optical cable center and oversheath, has strengthened the withstand voltage properties of optical cable, and stressed in the groove of road of optical cable evenly is not easy to suffer damage, and has extended optical cable serviceable life;
2) use water-ring to replace traditional waterstop, make optical cable there is good block-water performance, simultaneously because water-ring is spaced, alleviated the weight of optical cable, reduced the optical cable production cost.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure, 1-metal reinforcement B, 2-water-ring, 3-pine sleeve pipe, 4-waterproof filling material, 5-optical fiber, 6-oversheath, 7-metal tape, 8-metal reinforcement A.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of Novel road groove optical cable, it comprises fiber unit, oversheath 6 and two metal reinforcement A8, oversheath 6 is pancake, fiber unit is arranged at the center of optical cable, oversheath 6 is coated on the fiber unit outside, and two metal reinforcement A8 are arranged at respectively symmetria bilateralis position in oversheath; Described fiber unit comprises water-ring 2, loose sleeve pipe 3, waterproof filling material 4, optical fiber 5, oversheath 6 and metal tape 7, be provided with waterproof filling material 4 between optical fiber 5 and loose sleeve pipe 3, be provided with a plurality of water-rings 2 between pine sleeve pipe 3 and metal tape 7, oversheath 6 is coated on the periphery of metal tape 7.Described fiber unit also comprises a metal reinforcement B1, and metal reinforcement B1 is arranged at the center of fiber unit.
