The fiber is sleeved with a spring, a joint, a lower metal sleeve, a soft sleeve and a fixed sleeve in sequence. The joint is composed of an upper joint and a lower joint. The bottom of the lower joint is fixed with the lower metal sleeve. The soft sleeve is sleeved at one end of the lower metal sleeve. The joint is installed in a through hole in the lower joint. The top of the fiber is fixed with a ceramic plug core through an upper metal sleeve. The ceramic plug core is provided with a fiber protective sleeve. The low-attenuation fiber connecting device is simple in structure, skillful in design, low in production cost, long in service life, fast in transmission speed, good in communication signal, large in capacity and high in stability.
Description
Technical field
The utility model relates to a kind of optical fiber, relates in particular to a kind of indoor low attenuation optical fiber coupling arrangement.
Background technology
Traditional optical fiber mostly adopts cold joint or hot melt to connect, and the advantage of cold joint is: it does not need fused fiber splice equipment, by simple crimping tool, utilizes MACHINERY JOINT to realize the permanent connection of single core or multi-core fiber, requires loose to construction environment yet.Shortcoming is: responsive to temperature humidity, temperature more the high life more short, later maintenance cost is higher, construction process requirement is meticulous, rate of signal attenuation is high, transmission speed waits many shortcomings slowly.And hot melt connect to need supporting heat sealing machine, not only the use cost height, move inconvenience, and because want the welding optic fibre two ends, difficulty of construction is big, loss is high.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, design is ingenious, production cost is low, long service life, communication signal is good, capacity rate is big, stability is high low attenuation optical fiber coupling arrangement.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of low attenuation optical fiber coupling arrangement; comprise optical fiber; be socketed with spring, joint, following metal sleeve, soft sleeve pipe and fixed sleeving on the described optical fiber successively; described joint is made of top connection and lower sub; the bottom of lower sub is connected and fixed with following metal sleeve, and soft casing pipe sleeve is connected on down an end of metal sleeve, and joint is installed in the through hole of lower sub; fixedly there is ceramic insertion core at the top of described optical fiber by last metal sleeve, and fiber boot is installed on the ceramic insertion core.
Described optical fiber is made by glass fiber material, and the periphery of described optical fiber is provided with polymethyl methacrylate materials layer, low smoke and zero halogen environment-friendly materials layer and modified PVC layer successively.
The beneficial effects of the utility model are: the utility model design is ingenious rationally, efficiently solves the shortcoming that traditional cold joint formula optical fiber exists.This product has low decay, transmission speed is fast, communication signal good, capacity rate is big, stable high characteristics.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is decomposition texture synoptic diagram of the present utility model.
Fig. 2 is the structural representation of optical fiber.
Embodiment
With reference to Fig. 1, Fig. 2; a kind of low attenuation optical fiber coupling arrangement; comprise optical fiber 1; be socketed with spring 2, joint 3, following metal sleeve 4, soft sleeve pipe 5 and fixed sleeving 6 on the described optical fiber 1 successively; described joint 3 is made of top connection 31 and lower sub 32; the bottom of lower sub 32 is connected and fixed with following metal sleeve 4; soft sleeve pipe 5 is socketed in down an end of metal sleeve 4; joint 3 is installed in the through hole of lower sub 32; fixedly there is ceramic insertion core 8 at the top of described optical fiber 1 by last metal sleeve 7, and fiber boot 9 is installed on the ceramic insertion core 8.
Described optical fiber 1 is made by glass fiber material, and the periphery of described optical fiber 1 is provided with polymethyl methacrylate materials layer 11, low smoke and zero halogen environment-friendly materials layer 12 and modified PVC layer 13 successively.
Polymethylmethacrylate also is called the PMMA plastics, and its proportion is less than half of simple glass, and the shatter-resistant ability but exceeds several times; It has good insulation performance and physical strength; Acid, alkali, salt there is stronger decay resistance; And easily processing again.
The low smoke and zero halogen environment-friendly materials have: (1) tensile strength is bigger than general PVC electric wire: general PVC material tensile strength is greater than 1.05Kgf/mm2, and the low smoke and zero halogen material tensile strength is greater than 1.2Kgf/mm2.(2) has good weatherability (30 ℃～105 ℃); (3) possesses good pliability (hardness is 80-90); (4) has non-moving property; Can not produce poisonous black smoke when (5) burning; (6) have higher specific insulation: the PVC material is generally 1012～1015 Ω/cm3, and the low smoke and zero halogen material is greater than 1016 Ω/cm3; (7) have good high pressure resistant property: more than the general anti-10KV of PVC material, and the low smoke and zero halogen material is up to more than the 15KV; (8) has better elastic and viscosity.
The utility model design is ingenious rationally, efficiently solves the shortcoming that traditional cold joint formula optical fiber exists.This product has low decay, transmission speed is fast, communication signal good, capacity rate is big, stable high characteristics.The coherent detection data symbols of this product merges and is higher than national requirements, and concrete data are:
ILA：0.14dB；RLA：51.5dB
ILB：0.21dB；RLB：51.7dB
In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
