Abstract
The invention discloses a sealing protection structure inside a cable. The sealing protection structure comprises a protection cover which is hollow, a reinforcing rod is arranged in the center of the protection cover, and a plurality of optical fibers are arranged around the reinforcing rod and are arranged inside the protection cover. The sealing protection structure is simple, low in manufacturing cost and good in effect. A plurality of layers of materials are utilized for protecting internal components, the phenomena of fracture and the like are avoided, signals can be transmitted smoothly, the frequency that maintaining persons maintain circuits is reduced, and labor intensity is reduced.
Description
Technical field
The present invention relates to a kind of protection structure, especially relate to the seal protection structure of a kind of optical cable inside.
Background technology
Optical cable (optical fiber cable) is mainly by light transmitting fiber (thin glass fiber as hair) and plastic protective sleeve pipe and plastic peel formation, there is no the metals such as gold, silver, copper aluminium in optical cable, generally without recovery value.Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, and the also coating outer jacket that has, in order to realize a kind of communication line of optical signal transmission.Optical cable is the main delivery means of the various Information Networks of current information society.If " internet " is called " information highway ", so, cable network is exactly the foundation stone of Infobahn---cable network is the physics route of internet.In case certain optical cable wrecks and blocks, " information highway " of this direction namely cracks bad.By the information of optical cable transmission, except common phone, telegram, fax, the TV signal in addition of a large amount of transmission now, the information that can not interrupt a moment such as bank transfer, quotations on the stock market.At present, the transmission mode of toll communication optical cable is developed to SDH by PDH, it is even higher that transfer rate develops into 2.5GB/S, 4 * 2.5GB/S, 16 * 2.5GB/S by originally 140MB/S, that is to say, a pair of fibre core can be opened 30,000,120,000,480,000 even to more multi-path call development.Large transmission capacity like this, optical cable in a single day blocking-up not only brings about great losses to telecommunication department, and because communication is not smooth, can cause inconvenience to broad masses, as the computer user could not get on to the Net, stock market can not be known, bank money can't carry out, long distance deposits and withdrawals comes to naught, various information can't be transmitted., in outlying mountain area,, in case interruption of optical cables will make the whole county even shut off oneself from society in optical cable several counties along the line, become isolated island in communication.The loss of causing for office of Party, government and army and the people can't be estimated.The optical cable of selling on market, because its sealing effectiveness is not satisfactory, causes in use for some time, easily occurs causing the phenomenon that cracking even leaks inner member to be damaged or disturb, and affects the transmission of signal.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art; the seal protection structure of a kind of optical cable inside is provided; the simple structure of sealing protection structure; cheap for manufacturing cost, effective, utilize the multilayer material to protect inner member; the phenomenon such as avoid occurring breaking; the transmission that has guaranteed signal is happy, has reduced the maintenance of maintenance personal to circuit, has reduced labour intensity.
Purpose of the present invention is achieved through the following technical solutions: the seal protection structure of a kind of optical cable inside; the protective sleeve that comprises inner hollow; the center of described protective sleeve is provided with stiffener, is provided with some optical fiber tubes around described stiffener, and described optical fiber tube is arranged on protective sleeve inside.Stiffener, as a kind of support component, guarantees that the whole piece optical cable has certain hardness, phenomenon crooked and that fracture can not occur easily,
Be provided with sheath between described protective sleeve and optical fiber tube.Sheath, for the protection of optical fiber tube, is not subjected to the interference of extraneous weather.
Be provided with organdy between described sheath and protective sleeve.
Be provided with greasy for preventing water between described sheath and optical fiber tube., by greasy for preventing water, can prevent that extraneous water from destroying the optical fiber in optical fiber tube, guarantees the serviceable life of optical fiber.
Described optical fiber tube is evenly distributed on the surrounding of stiffener.
In sum; the invention has the beneficial effects as follows: the simple structure of sealing protection structure; cheap for manufacturing cost; effective; utilize the multilayer material to protect inner member, the phenomenon such as avoid occurring breaking, guaranteed that the transmission of signal is happy; reduce the maintenance of maintenance personal to circuit, reduced labour intensity.
Description of drawings
Fig. 1 is diagrammatic cross-section of the present invention.
Mark and corresponding parts title in accompanying drawing: 1-protective sleeve; 2-organdy; 3-sheath; 4-greasy for preventing water; 5-optical fiber tube; 6-stiffener.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
As shown in Figure 1; the seal protection structure of a kind of optical cable inside, comprise the protective sleeve 1 of inner hollow, and the center of described protective sleeve 1 is provided with stiffener 6; be provided with some optical fiber tubes 5 around described stiffener 6, described optical fiber tube 5 is arranged on protective sleeve 1 inside.Stiffener 6, as a kind of support component, guarantees that the whole piece optical cable has certain hardness, phenomenon crooked and that fracture can not occur easily, and optical fiber tube 5 is evenly distributed on the surrounding of stiffener 6, guarantees the safety of internal optical fiber.
Be provided with sheath 3 between described protective sleeve 1 and optical fiber tube 5.Sheath 3, for the protection of optical fiber tube 5, is not subjected to the interference of extraneous weather.
Be provided with organdy 2 between described sheath 3 and protective sleeve 1.Organdy 2 claims again Bali voile/organdy, and organdy 2 is a kind of thin transparent fabrics of knitting system with plain weave.Longitude and latitude all adopts thin special combing over-twisted yarn, and in fabric, thread count is smaller,, due to " carefully ", " rare ", adds heavy twist, makes fabric thin transparent.The raw material of organdy 2 has cotton textiles, polyester-cotton blend., through weft yarn, or be single thread in fabric, or be strand.Organdy 2 is different by processing, and organdy 2 is divided into stained glass yarn, bleaching organdy, paint glass yarn, yarn-dyed jacquard organdy etc.The quality of organdy fabric is thin, and feel is very refreshing, and the cloth hole is clear, and transparent air-permeable is used for the winding binding to optical fiber tube 5.
Be provided with greasy for preventing water 4 between described sheath 3 and optical fiber tube 5., by greasy for preventing water 4, can prevent that extraneous water from destroying the optical fiber in optical fiber tube 5, guarantees the serviceable life of optical fiber.
Described optical fiber tube 5 is evenly distributed on the surrounding of stiffener 6.Be uniformly distributed and be convenient to the arranging of optical fiber tube 5, visual effect is attractive in appearance, has also guaranteed the security of optical fiber tube 5 simultaneously.
Take aforesaid way, just can realize preferably the present invention.
