The utility model has the advantages that the rigidity is strong, the heat transfer coefficient is small, the vapor condensation is not easily caused, and sheet materials have less dosage, the cost is low, the stressing is small, the specific tenacity and the specific stiffness are high, the deflection or the long-term creep is not easily caused, the service life is long, and the protecting effect and the sealing effect of the box body can be effectively guaranteed.
Description
Technical field:
The utility model relates to a kind of optical fiber cable section box board.
Background technology:
Fiber cable cross connection box is a kind of connection device that optical cable Cheng Duan, jumper connection are provided for trunk layer optical cable, wiring layer optical cable, because it generally is to be installed in the open air, therefore can support weather and the bad working environment that is subjected to drastic change exactly to its most basic requirement, in other words, it will have waterproof airsetting knot and the strong characteristics of rigidity (shock resistance damage capability).Want by keeping the stable, reliable of the above-mentioned performance of fiber cable cross connection box, thereby be very very difficult the serviceable life that guarantees fiber cable cross connection box, this has just proposed the very requirement of strictness to the material and the technology of fiber cable cross connection box casing.
At present, the fiber cable cross connection box casing of prior art generally is to be that main metal boxboard is made by irony or stainless steel, though the strong shock resistance of metal boxboard, but, because the heat conductivility of metal boxboard is more intense, therefore the temperature of casing can change rapidly with the variation of outside air temperature, especially when outside air temperature descends, heat in the casing will transmit outside case, thereby causes the box house non-uniform temperature, and then causes gas flow in the case, when the cabinet wall surface temperature is lower than the saturation temperature of water vapor in the case, will cause the inwall condensation vapor, or claim condensation, this is that fiber cable cross connection box least allows to accept.Therefore the poor performance because metal boxboard waterproof vapour condenses causes the metal boxboard to be doomed can not used on the fiber cable cross connection box casing in a large number.
In order to solve the problem that has condensation vapor when the metal boxboard uses, adopted a kind of glass to strengthen unsaturated polyester die plastic (SMC) at present on the industry and claimed sheet molding compound to replace metal again as the material of doing optical fiber cable section box board.Because the heat transfer coefficient of this sheet molding compound only is the ppt of metal, it is slower to conduct heat, therefore the airflow convection time can extend in the casing, temperature in the casing can reduce gradually, the saturation temperature of steam also can decrease, be difficult for causing condensation vapor, this is that the boxboard of current polymer composite compression moulding is applied to the key factor that fiber cable cross connection box is promoted.But, adopt the boxboard of sheet molding compound compression moulding still to have a defective, promptly in order to satisfy the physical strength of fiber cable cross connection box casing, that is to say, in order to guarantee that casing has stronger rigidity, this class sheet molding compound boxboard tend to thick reach ten surplus the millimeter, and the bigger negative role of boxboard thickness is that the sheet material use quantity is big, the cost height, unrelieved stress in the forming process is big, specific strength and specific stiffness are low, easily cause the flexural deformations of chamber door or long-term creep, thereby give the protection (IP66 of casing, IP65) sealing brings adverse effect, shortens the serviceable life of fiber cable cross connection box casing greatly.
The utility model content:
The technical problems to be solved in the utility model is, provide that a kind of not only rigidity is strong, heat transfer coefficient is little, be difficult for causing condensation vapor, and the sheet material use quantity is little, cost is low, stress is little, specific strength and specific stiffness height, be difficult for flexural deformations or long-term creep, long service life, can effectively guarantee the optical fiber cable section box board of casing exclusion seal effect.
Technical solution of the present utility model is that a kind of optical fiber cable section box board with following structure is provided: it comprises a wood-base fibre and particle panel material layer and two sheet molding bed of materials; Described wood-base fibre and particle panel material layer is between two sheet molding bed of materials; Described two sheet molding bed of materials and wood-base fibre and particle panel material layer are as a whole by the moulding of hot-die pressing mode.
After adopting above structure, compared with prior art, the utlity model has following advantage:
1, with to adopt sheet molding compound to make optical fiber cable section box board fully in the prior art different, because the utility model optical fiber cable section box board is by two-layer sheet molding compound and the compression moulding of one deck wood-base fibre and particle panel material hot-die, and the price of wood-base fibre and particle panel material is well below the price of sheet molding compound, therefore, it is the use amount of sheet molding compound that the utility model has not only reduced sheet material, reduced cost, and the heat transfer coefficient of boxboard also becomes smaller, thermal resistance is bigger, because the heat transfer coefficient of boxboard is smaller, so temperature descends when slow in the casing made from the utility model boxboard, the airflow convection time will extend in the casing, temperature in the casing will reduce gradually, and the saturation temperature of steam also can decrease, thereby is difficult for causing condensation vapor;
2, because the sheet molding compound that is adopted in the utility model optical fiber cable section box board and the forming method thereof has high fluidity characteristic preferably, in the hot-die pressing process, it can keep having good embedding and filling up effect with the crack microgroove on wood-base fibre and particle panel material top layer, thereby not only make sandwich construction in conjunction with good, and rigidity strengthens greatly, and can satisfy the requirement of physical strength in the YD/T988-2007 communication cable case industry standard fully.
3, soft relatively soft as the wood-base fibre and particle panel material of laminboard layer, it can absorb the unrelieved stress in the forming process, thereby improve the specific strength and the specific stiffness of boxboard, guarantee to be difficult for disturbing curved change or long-term creep after the demoulding of large tracts of land boxboard, and effectively guarantee the exclusion seal of casing and the serviceable life that has prolonged casing.
As a kind of improvement of the present utility model, described boxboard also can comprise a heat curing powder bed; Described heat curing powder bed is coated in the surface of one of them sheet moulding compound layer.Since the heat curing powder have high rigidity, high scoring resistance, high weather-proof and with the super excellent characteristics of basal body binding force, therefore its coating not only can further strengthen the impact resistance of boxboard, prolong the serviceable life of boxboard, and can also give the boxboard surface distinctive anti-paste, anti-graffiti, the anti-characteristics that stain, easily scrub cleaning, thereby reach anti-aging for a long time, improved the effect of apparent mass.
