Description
Technical field
The utility model is related to a kind of fiber cable joint sealing structures with elastic crush seal function.
Background technology
Cable splice closure is used on fiber optic network connecting and protection between optical cable and optical cable.The prior art is to meet
The straight-through and branch-type of cable splice closure connects the needs of function, and box body upper and lower cover and sealing strip will be designed to beat above and below
Open the simultaneously fixed Hafu type sealing structure of pairing.The optical cable of existing cable splice closure buries that connect hole usually soft by silicon rubber etc.
Elastic material is sealed, to ensure good gas-tight and water resistance, thus from the erosion of moisture, however fiber cable joint
For the environment temperature that box uses in -40 degree to+65 degree, temperature change is larger.However this kind of soft elasto material is in higher temperatures situation
After lower assembly, in the case where entering low temperature environment, soft elasto elastic properties of materials reduced performance, and volume-diminished, to reduce sealing
Performance.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiencies existing in the prior art, and provide a kind of structure design conjunction
The fiber cable joint sealing structure with elastic crush seal function of reason.
The technical scheme in the invention for solving the above technical problem is：
A kind of fiber cable joint sealing structure with elastic crush seal function, box body have for the optical cable across optical cable
It buries and connects hole, it is characterised in that：The optical cable bury connect hole from the inside to the outside successively elastic seal ring, elasticity squeeze module and squeeze spiral shell
Bolt, squeezing bolt has for the perforation across optical cable, and it includes front connector, rear connectors and compression spring that elasticity, which squeezes module,
Front connector, rear connectors are in circular ring shape, the both ends difference front connector of compression spring, on rear connectors, one end of front connector
It is against the one end for squeezing bolt, one end of rear connectors is against one end of elastic seal ring, and the other end of elastic seal ring is against
Optical cable, which buries, to be connect on the one end in hole, and optical cable, which buries, connects hole with for being screwed into the thread-rolling screw for squeezing bolt.
Cable splice closure needs internal qi of chong channel ascending adversely 60MPA, in+65 degree to -40 degree loop tests, and finishes after test under air pressure
Drop is very high to the material and structural requirement of product no more than 5MPA, present design can effectively product sealing problem, product it is former
The requirement of material has at low cost, the good advantage of performance.Product seal member is usually elastic material, this elastic-like material heat
The coefficient of expansion is larger, and at high temperature, volume expansion generates product casing larger pressure, is easy to make deformation of products, while bullet
Property material volume expansion itself when by product casing squeeze and self performance is affected, in low temperature, volume-diminished, be easy
Gas leakage, for this phenomenon, product increases elasticity in design and squeezes module, at high temperature, the expansion of elastic material volume, bullet
Property squeeze module compression, reduce to produce mouth shell influence, in low temperature, elastic material volume reduce, elasticity squeeze module return
Bullet carries out secondary extrusion, it is ensured that air tight to elastic material.
Preferably, several sliding grooves being axially arranged along rear connectors are fixed on rear connectors, in front connector
Several slide posts being axially arranged along front connector are fixed with, slide post is plugged in sliding groove.Using this structure so that
In narrow space, the guiding of front connector and rear connectors is more accurate.
Preferably, the other end of front connector and the other end of rear connectors offer the receiving for accommodating compression spring
Slot, the slot bottom of the holding tank are fixed with the connecting pole for being inserted into compression spring.Using this structure so that structure is compacter.
Preferably, elasticity squeezes tool in module, there are four the compression springs being equally spaced.
Preferably, fixed in rear connecting component, there are four the slide posts of spaced set.
The utility model compared with prior art, has the following advantages and effect：Sealing structure is easy to implement Fast Installation
It is fixed, and at high temperature, elastic material volume expansion, elasticity squeezes module compression, reduces the influence to producing mouth shell, in low temperature
When, elastic material volume reduces, and elasticity squeezes module rebound, and secondary extrusion is carried out to elastic material, it is ensured that and it is air tight, to have
Effect ensure that sealing performance.
