Description
Technical field:
The utility model relates to a kind of seal assembly, particularly relates to a kind of cable splice closure seal assembly that is used for cable splice closure.
Background technology:
Along with the communication technology constantly develops, FTTX (optical fiber access) popularizes, and the safety problem of fiber optic cable communications network operation also more and more is subject to people's attention.That the system of laying of outdoor optical cable connector box has is built on stilts, pipeline (tunnel) and direct-burried etc., and cable splice closure is as the important equipment that guarantees the fiber optic cable communications network, and the reliability of its sealing property is also just particularly important.
At present, what the buckling surface of domestic cable splice closure major part adopted is that traditional autohension silica gel seals, but the existence of this sealing means can not reuse and the problem of installation inconvenience; What fraction adopted in addition is that the patent No. that State Intellectual Property Office of the People's Republic of China announces is the cable splice closure seal assembly of the utility model patent description of ZL 200820132170.5, and this cable splice closure seal assembly adopts the banded sealing strip (or rubber strip) of elastic silica gel, the Width of the banded sealing strip of this elastic silica gel keeps flat, compress by upper and lower covers again and seal, but this sealing means, the sealing property of cable splice closure mainly leans on the wall pressure of banded sealing strip of body seam place elastic silica gel and housing to guarantee, just assembled the cable splice closure of finishing, its wall pressure can be guaranteed, but after after a while, because the ductility of the banded sealing strip of elastic silica gel and long-time stressed after lax, just reduced the wall pressure of seam crossing, water just is easy to be pressed in the cable splice closure go, and the water that enters then can cause optical fiber disconnected fine situation to occur; And sealing strip and sealing block are integral types, are shifted easily during single installation, need that other staff are auxiliary to install, and trouble is installed, moreover when sealing strip or sealing block damage, needs integral replacing, and maintenance cost is higher.
The utility model content:
The utility model provides the cable splice closure that a kind of sealing effectiveness is better, easy for installation and maintenance cost is lower seal assembly at above problem.
The utility model overcomes the above problems used technical scheme: a kind of cable splice closure seal assembly with following structure is provided, it comprises sealing strip and the seal modules that is located between fiber cable joint box base and the loam cake, described sealing strip is a banded structure, described seal modules is provided with optical cable and supports locating sleeve, sealing strip and seal modules are two structures independently, be provided with around the described seal modules be used for the fiber cable joint box base and on the groove that cooperates of the projection that covers, the Width of described sealing strip vertically is provided with, and the inboard at sealing strip two ends is provided with the rectangular recess that is used for the seal modules cooperation.
After adopting above structure, compared with prior art, the utility model is because sealing strip and seal modules are two structures independently, and the Width of sealing strip vertically is provided with, the inboard at sealing strip two ends is provided with the rectangular recess that is used for the seal modules cooperation, then sealing strip on the fiber cable joint box base groove and the cavity that forms of the groove of loam cake in after Width vertically is provided with, compress under the effect of fiber cable joint box base and loam cake at securing member again, guaranteed the wall pressure of sealing strip and fiber cable joint box base and loam cake, played good sealing function, guarantee that very sealing is not intake, so sealing effectiveness is better; Simultaneously sealing strip and seal modules are two structures independently, can put into separately in the groove on the fiber cable joint box base, only need a people to finish, simple installation then, and when sealing strip or sealing block damage, only need to change the sealing strip or the sealing block that damage and get final product, need not integral replacing, then maintenance cost is lower.
As improvement, the interior lateral surface in the centre position of described sealing strip is equipped with a plurality of rectangular protrusions that are used to prevent the sealing strip landing, then rectangular protrusions can prevent the sealing strip landing, can make simultaneously the workmen exactly sealing strip be put in the groove on the fiber cable joint box base again, so accurate positioning of sealing strip, can play the effect of sealing effectively, guarantee the utlity model has the better seal performance, and install also easier.
As further improvement, the medial surface of described seal modules is provided with quantity and the fibre-optical splice box advances the corresponding conical sealing unit in cable hole, the end face self sealss of conical sealing unit miner diameter end, then according to the diameter behind the optical cable baring, the front end of the cone seal unit of correspondence is cut off, the diameter of the diameter that requires clipped position after less than optical cable baring, subsequently optical cable is directly passed conical sealing unit, because the diameter of the clipped position diameter after less than optical cable baring, conical sealing unit envelopes optical cable the effect that just can play sealing according to the shrinkability of himself, need not on optical cable, to coat again one deck sealant tape or fluid sealant, so install more easy; And the end face of conical sealing unit miner diameter end originally was exactly sealing, and then untapped conical sealing unit need not to go sealing with original plug again, and sealing effectiveness will be significantly better than original plug.
As further improving, the male-tapered face of described conical sealing unit is provided with the projection of many annulars, then should being raised with of annular help strengthen the tensile force that conical sealing unit coats optical cable, assurance the utlity model has the better seal effect, and can prevent that conical sealing unit from rolling foremost and cause the into generation of the situation of water, so the stability of the sealing between conical sealing unit and the optical cable is better.
