Description
Technical field
The utility model relates to a kind of outdoor fiber active linker.
Background technology
Along with the development of the communication technology, Optical Fiber Transmission is more and more applied in communication system, in fiber-optic communications traffic link, frequent needs are at disparate modules, connect flexibly between equipment and system, but optical signal transmission is different from electric signal transmission, directly the termination of two optical fiber directly can not be connected, in prior art, there is the technology of the termination of two optical fiber being carried out melting connection, but melting connects and needs smelting equipment, greatly reduces work efficiency and dirigibility.
Utility model content
The utility model provides a kind of Fiber connection, transfers flexibly and easily and the good outdoor fiber active linker of water resistance.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of outdoor fiber active linker, it is characterized in that, comprise the optical cable with cable core and oversheath, described cable core is by optical cable body and reinforcement is stranded forms, the end of optical cable body is stretched out oversheath and is provided with fiber connector, is provided with hermetic water-proof structure between the two ends of described oversheath and optical cable body.
Described hermetic water-proof structure is included in the marine glue seal that oversheath end is arranged with the optical cable body place of separation.
Described hermetic water-proof structure also comprises the heat-shrink tube be covered on waterproof sealing colloid.
Described reinforcement is made up of the aramid yarn with sheath.
Described optical cable body comprises inner sheath, and have tightly packaged fiber and aramid yarn packed layer in described inner sheath, described tightly packaged fiber is positioned at the center of polyvinyl chloride inner sheath, and described aramid yarn packed layer is evenly distributed on around tightly packaged fiber.
Described oversheath is low smoke and zero halogen oversheath.
Optical cable body in described oversheath and reinforcement are symmetrical arranged and mutually stranded.
Optical cable body is wrapped up by oversheath by outdoor fiber active linker of the present utility model, the two ends of optical cable body are stretched out the two ends outlet of oversheath and are connected with attachment plug, in use, realize switching by the two ends plug of optical cable body to connect, convenient, flexible, also be provided with the reinforcement for improving overall tensile strength in use in oversheath simultaneously, reinforcement is filled in the rest in oversheath outside removing optical cable body, make close structure in the endoporus of oversheath, prevent optical cable body from rocking back and forth in oversheath, avoid optical cable body wear, the exit, two ends of oversheath is also provided with the hermetic water-proof structure because anti-sealing or other dirts enter, sealing waterproof construction on the one hand anti-sealing to enter in oversheath and reinforcement in oversheath and optical cable body and flow back to the other end access arrangement of connector, prevent the reinforcement in movement or transportation in oversheath from spinning off in oversheath by external force on the other hand, affect result of use and serviceable life.
Further; each optical cable body has pvc sheath; tight-buffered fiber optic cable and aramid yarn packed layer is enclosed with in pvc sheath; tight-buffered fiber optic cable is positioned at the center of pvc sheath; aramid yarn packed layer is evenly distributed on around tight-buffered fiber optic cable; the tight-buffered fiber optic cable at sheath center is protected, further increases tensile strength simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of outdoor fiber active linker embodiment of the present utility model;
Fig. 2 is A-A place cut-open view in Fig. 1.
Embodiment
The embodiment of outdoor fiber active linker of the present utility model: as shown in Figure 1-2, comprise optical cable, optical cable is formed by optical cable body 3 and the mutually stranded and extrusion molding low smoke and zero halogen oversheath 1 of aramid yarn reinforcement 5, optical cable body 3 has pvc sheath, center in pvc sheath is provided with tightly packaged fiber 6, certainly, in other embodiments, the optical fiber in optical cable body 3 can be more than 2 cores or 2 cores.Also be provided with the aramid yarn packed layer 31 be evenly distributed on around tightly packaged fiber 6 in pvc sheath, the simple optical fiber 6 of aramid yarn packed layer 31 pairs of centers plays a protective role, and improves the tensile strength of optical cable body 3 simultaneously.Optical cable body 3 in optical cable body twists together mutually with aramid yarn reinforcement 5, reinforcement 5 is made up of the aramid yarn of band sheath, further increase tension and the bending strength of whole flexible jumper, certainly, in other embodiments, aramid yarn reinforcement also can replace with high-carbon steel wire or gasket for packing.The two ends outlet of oversheath 1 is stretched out at the two ends of optical cable body 3 and its end is connected with attachment plug 4, two ends optical cable body 3 extended position of oversheath 1 is provided with waterproof sealing structure 2, this waterproof sealing structure 2 is made up of marine glue seal and heat-shrink tube, marine glue is smeared shutoff and form marine glue seal at optical cable body 3 with oversheath 1 place of separation, heat-shrink tube is set in marine glue seal and seals further outward, such double seal ensure that water and dust can not enter in oversheath, outdoor any rugged surroundings can be adapted to, it also avoid in mobile transportation, optical cable body and the aramid yarn reinforcement of optical cable body end are worn and affect result of use and serviceable life, in other embodiments, the mode of directly smearing fluid sealant can be adopted to seal.
There is outside outdoor fiber active linker simple optical fiber of the present utility model three layers of sheath and one deck aramid yarn packed layer; more effective to the protection of optical fiber; avoid because causing optical fibre damage by external force; two aramid yarn reinforcements are provided with in oversheath; be not provided with again aramid yarn packed layer with in the sheath of optical cable body simultaneously; two-layer like this aramid yarn substantially increases the bulk strength of connector, ensure that in use survivable, adds serviceable life.
