Description
Technical field
The invention belongs to optical communication equipment technologies, and in particular to what a kind of cable splice closure screw squeezed, which draw, connects cable mouth
Sealing structure.
Background technique
Cable splice closure shields after mainly connecting to the optical cable on fiber optic network with optical cable, between optical cable
Connecting, which has, leads directly to difference two ways, this needs connector box to be designed to have inside permission straight-through optical cable access optical cable connector box
Structure.In the non-end access connector box of optical cable, need for the access part bending of optical cable to be in U-shape, and U-shaped part is whole
It is inserted into cable splice closure, and is fixed and seals, meanwhile, conventional cable fibre core minimum bend is partly 30 millimeters, optical cable cable mouth
Width need to be greater than 60 millimeters.The sealing structure of the existing U-shaped part to optical cable mostly uses greatly thermal contraction sealing or conventional mechanical to squeeze
Means of press seals applies man-hour requirement and carries heating equipment, give field construction band although thermal contraction sealing sealing performance is relatively stable
It is inconvenient to come, and conventional mechanical squeezes sealing, by the elastic sealing element of a monoblock type to the Liang Ge branch of optical cable U-shaped part
Whole to squeeze sealing simultaneously, crush resistance is big, and sealing performance is poor.
Summary of the invention
It is an object of the invention to overcome the above shortcomings in existing sealing technique, and provide a kind of fiber cable joint
Drawing for box screw extruding connects cable mouth sealing structure.This structure is suitable for the unilateral cable splice closure into straight-through optical cable.
Technical solution used by the present invention solves the above problems is:
What a kind of cable splice closure screw squeezed, which draw, connects cable mouth sealing structure, it is characterised in that: including sealed body, sealing
Part and squeeze fixing piece, the sealed body be equipped with the inner cavity for accommodating sealing element and allow the U-shaped end of optical cable integrally through it is logical
Hole, the sealing element are equipped with several through-holes and spacing block for allowing optical cable to pass through, and spacing block is set between through-hole, if being formed
A dry independent sealing inner cavity, the extruding fixing piece are set on sealed body, to described independent sealed interior intracavitary close
Envelope component carries out extruding sealing, and the sealing element and extruding fixing piece all have the opening for allowing optical cable to be caught in.
Cable splice closure needs internal qi of chong channel ascending adversely 60Kpa, does loop test between -40 degree in+65 degree, and after finishing test
Air pressure cannot be below 40Kpa, very high to the material and structural requirement of product, and it is close that present design can effectively solve cable splice closure
Envelope problem, sealing element are silicon rubber elastomeric material, and the coefficient of expansion is bigger, by setting two independent optical cable sealings
Chamber, sealing ring sidewall thickness is relatively uniform, and sealing element volume is reduced, and individually carries out extruding sealing, optical cable to sealing ring and optical cable
And optical cable seals inner cavity uniform force, the influence because of temperature change to sealing performance is effectively reduced, sealing performance is more stable.
Further, preferably, the sealed body is equipped with tongue or groove, the spacing block is equipped with corresponding recessed
Slot or tongue are fixed along axial splicing.Using this structure, the intensity of sealed body can be enhanced, prevent sealed body from squeezing
Deformation when pressure fixing piece squeezes sealing element guarantees that sealing performance is stablized, and easy to operate, at low cost.
Further, it preferably, the spacing block is single part, is fixed on the sealed body by screw.It adopts
With this structure, the difficulty of processing of sealing element can be reduced and improve sealing structure to the receiving dynamics of air pressure in box body, guaranteed
Sealing performance is stablized, this structure is more appropriate to the cable splice closure for needing qi of chong channel ascending adversely 60KPA to test.
Further, preferably, sealing element front end lining framework can be prevented from squeezing and be fixed using this structure
When part squeezes sealing element, sealing element, which is crossed, to be squeezed into box body, seal failure, guarantees that sealing performance is stablized.
Further, preferably, the sealing element is made of the splicing of multiple seal members.Using this structure, Ke Yigen
Appropriate seal component is selected according to optic cable diameter size, reduces cost, improves the versatility of product.
Further, it preferably, the extruding fixing piece distinguishes formula structure for two, is fixed along axial splicing.Using this knot
Structure facilitates cable outer diameter to be directly caught in and squeezes in fixing piece.
This technology is compared with the prior art, have the following advantages that and effect:
1. components are less, at low cost, operate simpler.
2. sealing inner cavity by two independent optical cables of setting, two relatively independent sealing structures are formed, shell is reduced
The performance indicator of material, operation is simpler, and sealing performance is more stable.
3. when cable splice closure is not necessarily to straight-through cable access and requires, it can be used as two individual cable mouths to use, leakproofness
It can be unaffected.
