Abstract

The utility model discloses a self-bearing type rubber-insulated wire optical cable comprising an optical cable unit at the center, a rectangular jacket and reinforcing pieces, wherein the rectangular jacket wraps the periphery of the optical cable unit, and the section of the jacket is rectangular; the reinforcing pieces are arranged in the rectangular jacket and are symmetrical relative to the optical cable unit; a torn slot is arranged at each of two long edges of the rectangular jacket; the self-bearing type reinforcing pieces and a supporting jacket wrapping the periphery of the self-bearing type reinforcing pieces are arranged on the short edge sides of the rectangular jacket; and the supporting jacket and the rectangular jacket are formed by integral extrusion molding. The self-bearing type rubber-insulated wire optical cable is simple to manufacture, consumes few materials, and is more convenient to lay and install.

Description

The self-bearing type covered wire cable

Technical field

the utility model relates to a kind of self-bearing type covered wire cable.

Background technology

optical cable is combined by multifiber, as the optical fiber of transmission medium of new generation, compares with copper medium, and be all to be greatly improved aspect security, reliability or the network performance.In addition, the broadband of Optical Fiber Transmission is well beyond copper cable, and the ultimate range of its support reaches more than two kilometers, is the inevitable choice of the fairly large network of assembly.Because optical fiber cable has advantages such as anti-electromagnetic interference (EMI) property is good, strong security, speed is fast, transmission capacity is big,, be in and seldom use with occasion so its price is also comparatively expensive.Along with the price reduction of line module and user's connector and popularize, the usable range of optical fiber will obtain unprecedented expansion, and optical cable will enter into a brand-new development and stage of popularization again, and this is the inexorable trend of Communication Development.

optical cable adopts built on stilts method of laying usually when installing and insert, in the prior art, and during built on stilts laying optical cable, the mode that mostly adopts discrete support member to hang optical cable, this has brought great inconvenience to laying installation.

Summary of the invention

In order to overcome existing optical cable inconvenient deficiency when built on stilts the laying, the utility model provides a kind of self-bearing type covered wire cable that lays of being convenient to make somebody a mere figurehead .

The technical scheme of the utility model is: a kind of self-bearing type covered wire cable; Comprise the fiber unit that is positioned at the center, be coated on the rectangular rectangle sheath of fiber unit periphery and xsect, be arranged on the rectangle sheath and with respect to the reinforcement of fiber unit symmetry; Two long limits of rectangle sheath respectively are provided with a tearing groove; The short brink of rectangle sheath is provided with the self-bearing type reinforcement and is coated on self-bearing type reinforcement outer support sheath, said support sheath and rectangle sheath one extrusion moulding.

said self-bearing type reinforcement is a steel wire.

said reinforcement is glass fiber reinforced plastics rod (FRP rod) or steel wire.

The material of said rectangle sheath can be flame-proof polyvinyl chloride (PVC) or low smoke halogen-free flame-retardant polyolefin (LSZH) or the like.

said fiber unit can be made up of one to four painted coated fiber, also can be the four-core fibre ribbon.

The utility model has the advantages that:

1, the utility model are not only made simply, consumptive material is few; And laying installation is comparatively convenient; Be applicable in the Access Network or the local network of users by the optical cable of introducing in the outdoor inlet chamber; And buildings is introduced the wiring when cable, particularly indoor or outdoors are built on stilts to be introduced in the comprehensive wiring.

The setting of tearing groove in , the utility model has improved the stripping performance of optical cable, is convenient to the strip off optical cable and exposes fiber unit.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the synoptic diagram of a kind of embodiment of the utility model;

Fig. 2 is the synoptic diagram of the another kind of embodiment of the utility model.

wherein: 1 fiber unit; 2 rectangle sheaths; 3 reinforcements; 4 tearing grooves; 5 self-bearing type reinforcements; 6 support sheath.

Embodiment

embodiment: as depicted in figs. 1 and 2; A kind of self-bearing type covered wire cable; Comprise the fiber unit 1 that is positioned at the center, be coated on the rectangular rectangle sheath 2 of fiber unit 1 periphery and xsect, be arranged on rectangle sheath 2 and with respect to the reinforcement 3 of fiber unit 1 symmetry; Two long limits of rectangle sheath 2 respectively are provided with a tearing groove 4; The short brink of rectangle sheath 2 is provided with self-bearing type reinforcement 5 and is coated on the support sheath 6 outside the self-bearing type reinforcement 5, said support sheath 6 and rectangle sheath 2 one extrusion moulding.

said self-bearing type reinforcement 5 is a steel wire.

said reinforcement 3 is glass fiber reinforced plastics rod (FRP rod) or steel wire.

The material of said rectangle sheath 2 can be flame-proof polyvinyl chloride (PVC) or low smoke halogen-free flame-retardant polyolefin (LSZH) or the like.

said fiber unit 1 can constitute (see figure 1) by one to four painted coated fiber, also can be four-core fibre ribbon (see figure 2).

the utility model is not only made simply, consumptive material is few; And laying installation is comparatively convenient; Be applicable in the Access Network or the local network of users by the optical cable of introducing in the outdoor inlet chamber; And buildings is introduced the wiring when cable, particularly indoor or outdoors are built on stilts to be introduced in the comprehensive wiring.

The setting of tearing groove 4 in the utility model has improved the stripping performance of optical cable, is convenient to the strip off optical cable and exposes fiber unit 1.

Only be the concrete exemplary applications of the utility model more than , the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
