Abstract
The utility model discloses an air-blowing optical cable with no center reinforcement member. The air-blowing optical cable comprises a cable core (1) and a protective sleeve (2) wrapping the cable core (1). The cable core (1) comprises a loose tube (3) and optical fibers (4) wrapped in the loose tube (3), wherein the optical fibers (4) in the loose tube (3) are uniformly distributed; and gaps inside the loose tube (3) are filled with fiber paste (5). At least two reinforcement members (6) are disposed in the protective sleeve (2), wherein the reinforcement members (6) are uniformly distributed along the circumference of the protective sleeve (2), and the periphery of the protective sleeve (2) is provided with convex wrinkles (7). The beneficial effects of the air-blowing optical cable with no center reinforcement member are that the arrangement of convex wrinkles on the surface of the optical cable reduces the friction between the optical cable and an installation pipe, and thus the installation speed is conspicuously improved; the center reinforcement member in a cable core are replaced by reinforcement members disposed in the protective sleeve, so that the radius of the optical cable is substantially reduced, material is saved, and the installation is facilitated.
Description
Technical field
The utility model relates to a kind of air-blowing optical cable without central reinforce member.
Background technology
Optical cable mainly is by light transmitting fiber (thin glass fiber such as hair) and plastic protective sleeve pipe and plastic peel formation.Optical cable is the main delivery means of the various Information Networks of current information society.
The system of laying of optical cable comprises overhead type, direct burial and duct type, duct type generally namely is the air-blowing optical cable mounting means, adopt mode that high pressure draught blows with the optical cable lowering in the silicon core pipe of pre-plugged, blow the cable machine with high pressure, pressurized air at a high speed is blown into silicon core pipe, high pressure draught promotes the sealing gland piston, the sealing gland piston that is connected to like this end of cable forms the uniform pulling force of a setting to optical cable, blowing simultaneously cable machine hydraulic track conveying mechanism clamping optical cable in this is fed forward, erection mode is very simple and practical like this, although but existing optical cable surface all is smooth, but because larger with silicon core pipe surface of contact, it is still very large to rub, and blows to be not easy very much, and speed is very slow, and existing optical cable all is to be provided with a central reinforce member, the diameter of this optical cable is larger, and resistant to bending performance can be used the occasion abominable with environment, but when some environment do not include abominable occasion, cumbersome shortcoming is installed namely reveals.
The utility model content
The purpose of this utility model namely is to overcome the deficiency of present technology, and a kind of air-blowing optical cable without central reinforce member is provided, and solves following problem: (1) existing air-blowing optical cable because and mounting pipe between the friction excessive, cause installation rate very slow; (2) existing optic cable diameter is larger, and is cumbersome during installation.
The utility model is achieved through the following technical solutions: without the air-blowing optical cable of central reinforce member, the sheath that comprises cable core and parcel cable core, described cable core comprises loose sleeve pipe and is wrapped in the interior optical fiber of loose sleeve pipe, optical fiber in the pine sleeve pipe is evenly distributed, the fine cream of gap-fill in the pine sleeve pipe, be provided with at least two reinforcements in the described sheath, reinforcement distributes along the even circumferential of sheath, and the periphery of sheath also is provided with burr.
The xsect of described burr is triangle or rectangle.
Be provided with the plastic-coated steel band between described cable core and the sheath.
Be provided with waterstop between described cable core and the plastic-coated steel band.
The beneficial effects of the utility model are: the surface at optical cable arranges burr, namely reduced and mounting pipe between friction so that installation rate is significantly improved; Central reinforce member in the reinforcement replacement cable core is set in sheath, so that the radius of optical cable reduces greatly, not only saves material, and be beneficial to installation.

Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is two of structural representation of the present utility model;
Among the figure, 1-cable core, 2-sheath, 3-pine sleeve pipe, 4-optical fiber, the fine cream of 5-, 6-reinforcement, 7-burr, 8-plastic-coated steel band, 9-waterstop.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:
[embodiment]
As shown in Figure 1 and Figure 2, air-blowing optical cable without central reinforce member, the sheath 2 that comprises cable core 1 and parcel cable core 1, described cable core 1 comprise loose sleeve pipe 3 and the optical fiber 4 that is wrapped in the loose sleeve pipe 3, and the optical fiber 4 in the loose sleeve pipe 3 are evenly distributed, the fine cream 5 of gap-fill in the pine sleeve pipe 3, be used for blocking water, be provided with two reinforcements 6 in the described sheath 2, reinforcement 6 distributes along the even circumferential of sheath 2, reinforcement 6 is symmetrical at the two ends of cable core 1 in the present embodiment, and the periphery of sheath 2 also is provided with burr 7.
The xsect of described burr 7 is triangle or rectangle, and Fig. 1 is leg-of-mutton burr optical cable, and Fig. 2 is rectangular burr optical cable.
Be provided with plastic-coated steel band 8 between described cable core 1 and the sheath 2.
Be provided with waterstop 9 between described cable core 1 and the plastic-coated steel band 8.
Because the surface of this optical cable is provided with burr 7, when air-blowing is carried, and the friction between the mounting pipe namely reduces, so that transporting velocity is greatly improved.
