Abstract
The utility model discloses an optical cable assembly. The end part of a main cable is divided into a plurality of tail fibers through a deconcentrator; optical plugs are arranged at the end parts of the tail fibers; and protective armored pipes with elasticity are arranged on the outer sides of the tail fibers. In the optical cable assembly, the tensile and compression resistance properties of the tail fibers are increased through arranging the protective armored pipes on the outer side of the tail fibers, so as to prevent the tail fibers from being broken due to excessive bend or torsion, thereby achieving the purpose for effectively protecting the tail fibers. In addition, because the armored pipes are not required to be arranged in the main cable, the volume and the weight of the optical cable assembly are greatly reduced, thereby reducing the production cost and facilitating the transportation; a lightning protection measure is not required to be adopted at the section of the main cable when the main cable is laid, and the laying is simple and convenient, thereby reducing the construction cost.
Description
Technical field
The utility model relates to a kind of communication cable assembly, particularly a kind of cable assembly that is suitable for outdoor use.
Background technology
At present, optical cable is widely used in the data transmission system of the communications field.Optical cable needs to be connected with relevant device, in numerous outdoor cable assemblies, generally all adopts Waterproof Pigtail Cable to be connected with equipment appurtenance, perhaps melts fine mode with the armouring optical cable to equipment appurtenance and connects.In the prior art, the structure of Waterproof Pigtail Cable comprises main push-towing rope 1 as shown in Figure 1, and many tail optical fibers 3 are told by deconcentrator 2 in main push-towing rope 1 end, and tail optical fiber 3 ends are provided with optical plug 4.Generally about 2mm, this form of Waterproof Pigtail Cable is at engineering site, owing to lay and the very easy forked section of damaging of poling pulling for the diameter of the tail optical fiber 3 of Waterproof Pigtail Cable.The armouring optical cable improves greatly owing to increased the metal material resistance to tension in cable outer sheath, but cost also improves weight and diameter increase, simultaneously owing to have metal to draw thunder easily in the optical cable, also to carry out on-the-spot lightning protection measures, make transportation and engineering site lay difficulty and increase that cost increases.
Therefore, adopt two kinds of traditional optical cables recited above, all can't finely finish engineering site and can convenient-laying can not gain in weight again and the requirement of cost.
The utility model content
The technical problems to be solved in the utility model provide a kind of in light weight, cost is low, tensile strength greatly, not fragile, and the auxilliary cable assembly simply and easily of establishing.
In order to address the above problem, the utility model provides a kind of cable assembly, and the main push-towing rope end is divided into many tail optical fibers by deconcentrator, and the tail optical fiber end is provided with optical plug, and the described tail optical fiber outside is provided with rubber-like protection armour pipe.
Further, the two ends of described protection armour pipe embed respectively in deconcentrator and the optical plug.
Further, described protection armour pipe is made of spiral bonding jumper.
Further, described protection armour pipe is a corrugated tube.
The utility model is by increasing tension, the compressive property of tail optical fiber at tail optical fiber arranged outside protection armour pipe, prevent that tail optical fiber from because of excessive bending or reverse the fibre that breaks, playing the purpose of effective protection tail optical fiber.And, because the utility model need not be provided with the armour pipe in main push-towing rope, thereby reduced the volume and weight of cable assembly greatly, reduce production cost and be convenient to transportation; Auxilliary need not take lightning protection measures when establishing, auxilliaryly establish simple and conveniently, also reduce construction cost in the main push-towing rope section.
Description of drawings
Fig. 1 is the structural representation of Waterproof Pigtail Cable in the prior art;
Fig. 2 is the structural representation of an embodiment of cable assembly of the present utility model;
Fig. 3 is a local enlarged diagram embodiment illustrated in fig. 2.
Among the figure: 1. main push-towing rope, 2. deconcentrator, 3. tail optical fiber, 4. optical plug, 5. protection armour pipe.
Embodiment
The utility model is to protect tail optical fiber at a protection of the tail optical fiber arranged outside armour pipe of cable assembly, plays the effect that strengthens tail optical fiber tension, resistance to compression, anti-folding and torsional property.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
One embodiment of cable assembly as shown in Figures 2 and 3, in this embodiment, cable assembly comprises main push-towing rope 1, two tail optical fibers 3 are told by deconcentrator 2 in the end of main push-towing rope 1, are provided with optical plug 4 in the end of tail optical fiber 3.In other embodiments, main push-towing rope 1 can be told three or more tail optical fibers 3 by deconcentrator 2.Wherein, be respectively equipped with protection armour pipe 5 in the outside of every tail optical fiber 3, this protection armour pipe 5 should have certain elasticity, so that tail optical fiber 3 can be crooked to a certain extent, and convenient the installation.In order to make protection armour pipe 5 more firm, play the better protection effect, the two ends of protection armour pipe 5 can be embedded into respectively in deconcentrator 2 and the optical plug 4, make deconcentrator 2, protection armour pipe 5 and 4 one-tenth as a whole common protection tail optical fibers of optical plug.
In the above-described embodiments; protection armour pipe 5 is made of spiral bonding jumper, its similar volute spring, and this structure makes that tail optical fiber 3 can be easily crooked but can not curved transitions; also have good tension and compressive property simultaneously, protection tail optical fiber 3 can not damage.
In other embodiments, protection armour pipe 5 can be by intensity and all good material of elasticity, and for example the stainless steel material is made.At this moment, in order to realize easier bending, protection armour pipe 5 can be made into corrugated tube shape.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
