The connection of row protectiveness and fiber distribution.
Summary of the invention:
The purpose of the utility model is to provide a kind of fiber optic closure, emergence rate is improved, not accidentally farming season.
Above-mentioned purpose is realized by following technical scheme:
A kind of fiber optic closure, composition includes: box body, and the box body is bilateral symmetry, the box body end
Portion has one group of entrance hole, is placed with plug in the entrance hole, the entrance hole is provided with for bondage fiber optic cable
O-ring cable ring, the fixed anchor ear of optical cable is provided at the inlet wire aperture, apart from the fixed anchor ear 30- of the optical cable
The steel core card for fixing fiber optic cable strengthening core, pallet mounting plate and the box body is provided at 60mm to connect by screw
It connects, the pallet mounting plate is connect with welding pallet by slideway, and a surface of the welding pallet has slideway, institute
The contralateral surface for the welding pallet stated has the slideway side matched with slideway, and two welding pallets are connected by slideway, shape
At upper and lower lamination, the welding tray surface has one group of cloth fibre slot, is respectively disposed with one in the welding pallet two sides
A fiber optic protection heat-shrinkable T bush, ground extractor is provided on the pallet mounting plate, and the box body has shell close
Sealing groove, sealing element are placed in the housing seal slot, and the box body and box cover are tightly connected, in the welding pallet
Quadrangle is provided with the band for fixing optical fiber.
The utility model has the beneficial effects that
1. the straight-through and branch that the utility model is suitable for the system of laying such as the aerial of various structure optical cables, pipeline, direct-burried
Connection can endure severe condition such as vibration, shock, optical cable stretching distortion and strong temperature change.
2. the utility model is with good stability to heat, thermal energy radiation, air, ozone etc., diluted acid, salt water, oxidation
Agent, aliphatic hydrocarbon etc. have stronger resistance, using repeatable open-type seal assembly, to guarantee good air-tight water-proof performance.Molten
It connects and slideway and slideway side is set on pallet, realize multiple welding pallets by slideway and slideway side stacked in multi-layers, maximum accommodates 4 layers
Welding pallet increases the ability of splicing cables.
3. the connecting of the installation to micro- cable may be implemented in the utility model.The diameter of micro- cable is thinner, and the line-entering hole of connector box
Larger, if being directly connected to, connector box and micro-pipe are easy to fall off when by biggish pulling force.We are connected using connector box and micro-pipe
It connects, because the outer diameter of micro-pipe is identical as ordinary optical cable, can just make to connect between them using conventional fixing means in this way
Very securely.In addition, the micro-pipe outside connector box is connect using water-blocking joint with the micro-pipe that people's well is drawn, this ensure that even if
It will not be flowed in connector box having water in external micro-pipe, influence connecting quality.Micro- cable enters the fixed form of connector box
It is identical as general cable optical cable fixed form, it is all that strengthening core benefit is screwed in metal frame.Other parts in connector box
Seal means are identical as ordinary optical cable joint sealing mode.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.In figure, 13 be the end A optical cable, and 14 be the end B optical cable.
Specific embodiment:
Embodiment 1:
A kind of fiber optic closure, composition includes: box body, and the box body is bilateral symmetry, the box body end
Portion has one group of entrance hole 1, is placed with plug 2 in the entrance hole, the entrance hole is provided with for bondage optical fiber cable
The O-ring cable ring of cable is provided with the fixed anchor ear 3 of optical cable at the inlet wire aperture, apart from the fixed anchor ear of the optical cable
The steel core card 4 for fixing fiber optic cable strengthening core is provided at 30-60mm, pallet mounting plate 5 and the box body pass through spiral shell
Nail connection, the pallet mounting plate are connect with welding pallet 6 by slideway, and a surface of the welding pallet, which has, to be slided
Road, the contralateral surface of the welding pallet have the slideway side matched with slideway, and two welding pallets are connected by slideway
It connects, forms lamination up and down, the welding tray surface has one group of cloth fibre slot 7, in each cloth in welding pallet two sides
It is equipped with a fiber optic protection heat-shrinkable T bush 8, ground extractor 10, the box body tool are provided on the pallet mounting plate
There is housing seal slot, sealing element 11 is placed in the housing seal slot, and the box body and box cover are tightly connected, described
Welding pallet quadrangle be provided with the band 9 for fixing optical fiber.The box body is connect with hook 12.Described slideway one end
With block, when the slideway side of a welding pallet slides into the slideway of another welding pallet, block is prevented in the end of slideway
On-slip roadside skids off slideway.
Embodiment 2:
According to fiber optic closure described in embodiment 1, this product is suitable for various models, structure within diameter of phi 22mm
What the aerial of optical cable (single fiber), pipeline, direct-burried and people's well lays lead directly to connects with disagreement.
Directly pass through entrance hole if it is general cable and go out cable splice closure into two into two, if it is micro- cable, it should be micro-pipe
Into connector box and fixation, micro- cable enters out of micro-pipe, and fixed strengthening core.
Stripping fiber optic cables, remove oversheath, inner sheath, the loose draw, and cleaning removes petroleum filling paste in cable, stays 1.1--1.6m
Fiber lengths and 30--50mm strengthening core.
