Description
Technical field
What the utility model Road cable splice case related to is a kind of road, the assembling of the fiber cable joint on the road surface, pavement box that is embedded in the small towns, city that be applicable to.
Background technology
At present, the communication pipeline is more crowded, and Virtual network operator adopts underground piping to bury underground, and optical cable burial and construction engineering is bigger, the expense height.Development along with telecommunications, communication available space in city reduces greatly, in order to solve above-mentioned contradiction, the nearest road surface optical cable that occurs in the city, directly be embedded under the road surface, but the ordinary couplings box can not substitute use, cable splice closure structure more complicated Jia Ge Ang is expensive on the road surface, installs and uses inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of Road cable splice case at above-mentioned weak point, have sealed base, road cable clip tool sealing pedestal, coil fine plate, seal cover, its volume is little, good seal performance, road cable attended operation is convenient, the fixing seal of road cable (little cable) and sewer cable can be guaranteed simultaneously, and the pressure of road traveling vehicle can be born.
Road cable splice case takes following scheme to realize: the Road cable splice case structure comprises sealing pedestal, seal cover, optical cable clamping fixture seat, coils fine plate, the external side device of seal receptacle has several to enter the cable hole, advance the optical cable clamping fixture seat is housed on the cable hole, device has the fine plate of dish in the sealing pedestal, on the sealing pedestal seal cover is housed.The optical cable clamping fixture seat adopts screw thread and enters the cable hole and be connected, and device has intermediate plate in the optical cable clamping fixture seat, and intermediate plate constitutes by upper and lower two, is provided with anti-slip tank in the intermediate plate, and the employing screw is clamped in optical cable in the optical cable clamping fixture seat.The optical cable clamping fixture seat with advance cable hole link compress gasket be housed, seal cones is used for clamping sealing optical cable, and water is not leaked in the sealing pedestal.Coil that fine plate is provided with the optical fiber protective tube fixing hole, installs and fixes the hole, the heat-shrink tube protected location.Coil the fine plate cover plate of dish is housed on the fine plate.The fiber bundle splitter is sleeved on the interior optical cable metal coating of sealing pedestal and puts, and the fiber bundle splitter is assembled by splitter sleeve pipe and fiber bundle protection tube.
Operation principle:
When Road cable splice case uses; road cable (little cable) or sewer optical cable respectively by optical cable clamping fixture seat, the black box of sealing on the pedestal, enter the cable hole and enter the sealing pedestal; an end of road cable (little cable) or sewer optical cable is set with the fiber bundle splitter in the sealing pedestal; intermediate plate in the optical cable clamping fixture seat is fixed on optical cable in the clamping fixture seat endoporus by screw; sealing awl is fixed on optical cable in the cable hole simultaneously; fiber bundle in the optical cable is divided into some bundles through the fiber bundle splitter and enters by protection tube on the fine plate of dish, and optical fiber is embedded in after continuing in the heat-shrink tube protected location.Covering the fine plate cover plate of dish then gets final product.
The characteristics of Road cable splice case:
1, is applicable to the road surface joint of road cable system.
2, housing adopts the stainless steel material of high-quality, and volume is little, and the disk half slide structure advances between cable hole and the base and is connected with argon arc welding, coils between fine plate cover plate and the sealing pedestal to enclose with " zero " shape to seal, and can bear the pressure of road traveling vehicle.
3, can guarantee fixing, the sealing of road cable (little cable) and sewer cable simultaneously.Optical cable adopts semicircular intermediate plate to fix, and fiber cable jacket or stainless steel tube adopt cone seal.
4, adopt the fiber bundle splitter, the optical fiber in the central tube is divided into several groups 12 core units, and protect the into fine plate of dish with protection tube.
5, wouldn't with the cable hole of advancing seal with plug.
6, the fine plate of dish adopts circular configuration, guarantees the radius of curvature 〉=37.5mm of optical fiber, and the length of heat-shrink tube is 40mm only, has dwindled the overall dimension of connector box.
