Abstract
Disclosed in the utility model is a tightly sleeved type internal elliptical shaped branched optical cable that comprises a casing tube. A plurality of tightly sleeved optical fibers are arranged inside the casing tube; and the casing tube is arranged in a sheath. Fiber-reinforced composite plastic tubes are also arranged in the sheath and are arranged at the two sides of the casing tube. Protrusion marks that are stripping opening marks are arranged at the sheath. According to the utility model, the provided cable with the simple structure can be used conveniently. With utilization of the fiber-reinforced composite plastics, the strength of the optical cable is ensured and the optical cable cost is lowered.
Description
Technical field
The utility model relates to a kind of optical cable, particularly oval easily branched optical cable in a kind of tight cover type.
Background technology
Along with the development of technology development, communication has been not limited only to traditional narrowband telephone communication, broadband access network, broadband business such as IPTV, and comprehensive wiring system is as one of subsystem of building intelligent system, it is integrated telecommunication transmission system, by adopting single mode fiber cable, comprehensive wiring modes such as multimode optical cable and 6 class unshielded twisted pairs connect the speech ciphering equipment of each office building, data equipment, electronic communication equipment etc., and these equipment can be connected with outside related system, be the data image between building in the office building, it is practical that multimedia services etc. provide, reliably, flexibly, extendible medium channel is the basis of each light current and infosystem.The optical distribution cable that the comprehensive wiring scheme adopts at present traditional building generally adopts some tight tube fibers of bale breaking in the sheath, and the effect that suitable aramid fiber is strengthened is filled in the centre.In building, in the vertical wirings, be fit to tight tube fiber is successively branched to each dividing box.Traditional indoor comprehensive wiring optical cable major defect is: protect in the cable configuration and adopt the material of aramid fiber to strengthen pulling force, and the starting material domestic manufacturer of aramid fiber also is in the state that can't supply at present, cost is higher relatively, and large-scale the utilization is difficult to promote; Whole optical cable does not have fixing central reinforce member in optical cable, thereby is difficult to fix when having caused in building vertical wirings; This type of optical cable mainly is vertical wirings in building, in a certain certain floor if the operation that puts in a skylight that is difficult to that need isolate certain one or a few tight tube fiber.
The utility model content
At the deficiency that exists on the prior art, it is a kind of simple in structure, easy to use that the utility model provides, and adopted fibre-reinforced plastics to guarantee optical cable intensity and reduced oval easily branched optical cable in the tight cover type of optical cable cost.
To achieve these goals, the utility model is to realize by the following technical solutions:
Oval easily branched optical cable in a kind of tight cover type, comprise sleeve pipe, be provided with some tight tube fibers in the described sleeve pipe, sleeve pipe is arranged in the sheath, also be provided with the fibre-reinforced plastics pipe in the sheath, the fibre-reinforced plastics pipe is arranged in the both sides of sleeve pipe, and sheath is provided with the projection sign, and projection is masked as out the stripping mark.
Further, the xsect of described sleeve pipe is elliptical shape.
Further, described projection sign is structure as a whole with sheath.
Further, described tight tube fiber is arranged in the centre position of sleeve pipe.
Further, the xsect of described sheath is round-shaped.
Adopt the interior oval easily branched optical cable of tight cover type of technique scheme, owing to be provided with some tight tube fibers in the described sleeve pipe, sleeve pipe is arranged in the sheath, also be provided with the fibre-reinforced plastics pipe in the sheath, the fibre-reinforced plastics pipe is arranged in the both sides of sleeve pipe, and sheath is provided with the projection sign, and projection is masked as out the stripping mark, so avoided the utilization of aramid fiber, adopted fibre-reinforced plastics to guarantee optical cable intensity and reduced the optical cable cost; Two fibre-reinforced plastics pipes of embedding in sheath have guaranteed the hardness of sheath and whole optical cable, make in the work progress easier to be fixing.Because the xsect of described sleeve pipe is elliptical shape, so adopt oval-shaped thinnest part to open the mode of stripping note, the construction that is easier to put in a skylight.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the tightly structural representation of the interior oval easily branched optical cable of cover type of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, oval easily branched optical cable in a kind of tight cover type, comprise sleeve pipe 1, be provided with some tight tube fibers 3 in the sleeve pipe 1, sleeve pipe 1 is arranged in the sheath 4, also be provided with fibre-reinforced plastics pipe 2 in the sheath 4, fibre-reinforced plastics pipe 2 is arranged in the both sides of sleeve pipe 1, sheath 4 is provided with projection sign 5, projection sign 5 is for opening the stripping mark, and the xsect of sleeve pipe 1 is elliptical shape, and projection sign 5 is structure as a whole with sheath 4, tight tube fiber 3 is arranged in the centre position of sleeve pipe 1, and the xsect of sheath 4 is round-shaped.
The utility model is the interior oval easily branched optical cable of cover type tightly, be to adopt at sheath to embed two fibre-reinforced plastics pipes, the characteristics of the full medium of optical cable have been kept, thereby replace aramid fiber to strengthen having reduced cost, with respect to traditional cable configuration, the optical cable of sheath can improve the contraction of sheath effectively in addition.Because the fixedly existence of reinforcement is arranged, make optical cable in vertical wirings, be fixed in cross-connecting box and the dividing box better in the whole optical cable of while; Simultaneously with the bore design ovalization, be when reducing the protective cover material use on the one hand, simultaneously do the protrusion strip at oval-shaped thinnest part, reach out the effect of stripping note, like this at thinnest part, need not to isolate tight tube fiber by other instruments, finish whole optical-fiber network with indoor butterfly optical cable, wire jumper or shunt and lay.Be used for high-rise building vertical wirings in the world, optical cable needs branch out one or some optical fiber according to the every interlayer of the needs of actual conditions, makes that whole optical cable soft relatively aramid fiber knot in the dividing box of vertical shaft or cross-connecting box is easier to be fixing.In the branching process of floor gap, need not to isolate tight tube fiber by any instrument.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
