Abstract
The invention discloses a windmill-shaped lead-in optical cable. The windmill-shaped lead-in optical cable comprises a center reinforcement, fibers, micro cluster pipes, a reinforcement sheath and subunit sheaths, wherein the center reinforcement penetrates the reinforcement sheath along the axial direction of the reinforcement sheath, the plurality of subunit sheaths are uniformly distributed on the reinforcement sheath along the circumferential direction of the reinforcement sheath, the micro cluster pipes penetrate the subunit sheaths along axial directions, and the fibers penetrate the micro cluster pipes. Accessed subunits are easily separated, only needed subunits are separated during branching, other structures not accessing the subunits are not damaged, the windmill-shaped lead-in optical cable is particularly applied to branching during vertical wiring, the branching and introduction are realized through one optical cable, and compared to a conventional method, enormous installation time and installation cost are reduced.
Description
Technical field:
The present invention relates to a kind of windmill-shape leading in cable.
Background technology:
Existing butterfly leading in cable, the leading in cable family many for many floors such as circular cable must be introduced into many optical cables when introducing, and the conduit resource taken is many, is difficult to construction, and be only applicable to same floor and introduce.Although the leading in cables such as pencil cable, branch's cable are introduced into unit and concentrate in same optical cable, but expose internal introducing unit for there being different floor user must shift to an earlier date strip off oversheath when introducing, be not easy to the introducing of next floor user.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
The present invention is in order to solve the problem of above-mentioned prior art existence and to provide a kind of windmill-shape leading in cable.
The technical solution adopted in the present invention has: a kind of windmill-shape leading in cable, including center reinforcement, optical fiber, micro-bunch of pipe, reinforcement sheath and subunit jacket, described center reinforcement is arranged in reinforcement sheath along the axial direction of reinforcement sheath, some subunit jacket are distributed on reinforcement sheath along the circumferencial direction of reinforcement sheath, micro-bunch of pipe is arranged in subunit jacket along described axial direction, and optical fiber is arranged in micro-bunch of pipe.
Further, it is equipped with auxiliary reinforcement in described subunit jacket.
Further, described auxiliary reinforcement is paralleled with center reinforcement.
Further, the cross section of described subunit jacket is rectangular-shaped or toroidal.
Further, described subunit jacket is provided with dowel, and subunit jacket is connected on reinforcement sheath by this dowel.
Further, described subunit jacket is provided with tearing port.
Further, this tearing port described is cone-shaped, and along the length direction setting of subunit jacket.
There is advantages that
1) access subunit in the present invention is easily separated, only the subelement of needs is separated during branch, do not destroy the structure of other non-access subunits, being particularly easy to the vertical wirings time-division draws, make branch and be introduced through an optical cable and can realize, being compared to traditional method and save substantial amounts of set-up time and installation cost；
2) pulling force when center reinforcement in the present invention is mainly carried on cable wiring manufacture in building pipeline, auxiliary reinforcement auxiliary carrying construction pulling force, combining closely between both and sheath is possible to prevent using and the retraction of the protective cover material that extraneous factor causes in work progress, and then affects the biography light function of optical fiber；
3) the micro-bunch of available fingernail of pipe is peeled off, it is simple to fusing operation when multicore accesses, the most micro-bunch of pipe in use has certain protective effect, in turn ensure that optical fiber has certain remaining length simultaneously, can improve the tensile property of optical cable to a certain extent optical fiber；
4) when multi-user being introduced, under identical core number, the size of cable is better than the butterfly leading in cable under identical core number, can save conduit resource limited in building, allowing some leeway for fiber reforming in the future and upgrading, butterfly leading in cable accesses and is only limitted to same floor.
Accompanying drawing illustrates:
Fig. 1 is the cross sectional shape figure that present invention introduces optical cable.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, one windmill-shape leading in cable of the present invention, including center reinforcement 1, optical fiber 2, micro-bunch of pipe 3, subunit jacket 6 and reinforcement sheath 5, center reinforcement 1 is arranged in reinforcement sheath 5 along the axial direction of reinforcement sheath 5, some subunit jacket 6 are distributed on reinforcement sheath 5 along the circumferencial direction of reinforcement sheath 5, such as four shown in Fig. 1 unit sheath 6 is distributed on the circumferential direction of reinforcement sheath 5, center reinforcement 1 is made to be in the center of leading in cable, to bear main pulling force during construction.Being provided with micro-bunch of pipe 3 of an at least optical fiber 2 in inner chamber on each unit sheath 6, micro-bunch of pipe 3 is located in subunit jacket 6 along the axial direction of reinforcement sheath 5.
For increasing the carrying construction pulling force of optical cable, laying auxiliary reinforcement 4 in each subunit jacket 6, this auxiliary reinforcement 4 is positioned at the outside of micro-bunch of pipe 3.
Center reinforcement 1 in the present invention uses cross section to be circular steel wire or FRP, and therefore reinforcement sheath 5 is circular round tube for cross section.Certainly may be used without center reinforcement and the reinforcement sheath of corresponding cross sectional shape of other cross sectional shapes.The cross section of subunit jacket 6 is that rectangle is alternatively other geometries, such as circular.
Stripping for ease of micro-bunch of pipe, subunit jacket 6 is provided with at least one tearing port 7, this tearing port 7 can have various ways, it can be such as a 1 font mouth cut, one preferably tearing port 7 is the V-shaped tearing port arranged along its length, and the tear direction of this tearing port 7 is by along the center with center reinforcement 1 in the radial direction.
The present invention is for ease of peeling off subunit jacket 6 from reinforcement sheath 5, subunit jacket 6 is provided with dowel 8, subunit jacket 6 is connected on reinforcement sheath 5 by this dowel 8, the size of dowel 8 is much smaller than reinforcement sheath 5 and the size of subunit jacket 6, is therefore easy to the unit sheath 6 stripping from reinforcement sheath 5.
This product can be according to fiber count in the concrete number of floor levels of user and every floor number of users design subunit jacket 6 number and micro-bunch of pipe.During Specific construction, can required subunit jacket be torn when a floor, in order to the access of this layer of user, remainder can penetrate next floor by pipeline, reaches branch in this approach and introduces the purpose simultaneously completed.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
