Description
Technical Field
The invention relates to an optical cable connecting device, in particular to a field operation optical cable splice closure and a using method thereof.
Background
The military field operation optical cable is a metal-free optical cable which is specially designed for use under the conditions that rapid wiring or repeated winding and unwinding are needed in field operation and complex environment, and has light weight and convenient carrying; tensile strength, compressive strength and high strength-weight ratio; the flexibility is good, and the flexibility is easy; oil resistance, wear resistance and flame retardance; wide applicable temperature range and the like. The system is suitable for rapid wiring or repeated winding and unwinding of military field communication systems; radar, aviation and ship wiring; in oil field, mine, port, television field relay, communication line emergency repair and other places with harsh conditions.
For military use field operations optical cable is generally about 1 kilometer as a roll, and each roll is connected through a special joint, thereby realizing the laying of long-distance military optical cable. If a roll of military optical cable is damaged or broken, the cabling personnel can either replace a new roll of military optical cable or use the existing optical fiber splice closure for splicing during the actual cabling process. If a new reel of military optical cable is replaced, the damaged optical cable needs to be collected, and a new optical cable needs to be laid again, so that a large amount of laying time is wasted, the damaged optical cable needs to be provided with a special joint by a manufacturer, the use cost is greatly improved (one special joint is about 1000 yuan), once the field optical cable is damaged, the field optical cable can be connected by adopting a special field optical cable connector except for an optical cable splice closure at the disconnection position, but the field optical cable connector needs to be processed in a factory when the field optical cable connector is used, cannot be implemented in the field, and is greatly influenced by the environment. Therefore, optical fiber splice closures are generally used for splicing, but since optical fiber closures are designed for civil optical cables, the following disadvantages exist for military optical cables:
1. the volume is great (wide 170mm, long 410mm, thick 75 mm), and weight is heavy (2 kg), and for military use field operations optical cable lays in the field, lays and accomplishes the back, need carry out the rolling again, uses the optic fibre splice closure to continue the back in the department of continuing, because optic fibre splice closure is bulky, the reason that weight is heavy will lead to for military use field operations optical cable to receive and release inconveniently: the field operation optical cable is collected and released by adopting a portable field operation optical cable winding vehicle, and a splice closure with larger volume causes the winding vehicle to be blocked and can not rotate when being collected and released, thus occupying the winding vehicle space and causing great inconvenience;
2. the cable diameter difference is large, resulting in poor sealability: the conventional optical cable is thick, the field operation optical cable is small in diameter and large in diameter difference, and the sealing requirement of the field operation optical cable cannot be met and the field operation optical cable is not easy to connect by using the conventional connection box for connection;
3. the field operation optical cable is frequent in taking-up and paying-off and special in use environment, so that the conventional plastic shell splicing box is difficult to meet the mechanical and tensile properties and is easy to damage;
4. when the conventional optical cable junction box is used for splicing the optical cable with the breakpoint, the optical cable with the length of 50-100 centimeters is usually required to be remained in the junction box, so that the sheath of the optical cable is conveniently stripped for fusion splicing. In practical use, because the field optical cable is laid in a stretching mode, the field optical cable at two ends of the breakpoint is very difficult to pull back 50-100 cm to the breakpoint, a small section of optical cable is often connected to the breakpoint, and 2 splicing boxes are connected to meet the requirement for the optical cable allowance during splicing, and meanwhile, due to the increase of splicing points, the attenuation of the optical cable is increased, and the time for emergency call is increased;
5. when the existing field operation optical cable connecting equipment is used, a special field operation optical cable tail fiber is needed, and the cost is high.
The application numbers are: CN201621395542.4, publication no: the utility model of CN206248898U discloses a protection device for connecting and fixing field optical cables, which comprises two side walls and two box covers; the two side walls are spliced into a hollow cylinder, and splicing screw holes are formed in the splicing positions of the two side walls and longitudinally run through the side walls; the box cover is covered on openings at two ends of the side wall spliced into a cylinder, a sealing cover screw hole which is axially communicated is arranged at the sealing cover connecting part of the box cover and the side wall, and an axial wiring hole is formed at the top end of the box cover; the optical cable is fixedly connected in the side wall; the utility model discloses a only can play the effect that provides the protection to the cable department of continuing, after continuing to the field operations optical cable, stabilize not, when laying the field operations optical cable, be dragged very easily and tear, joint strength is very poor, the leakproofness is also very poor, get into dust easily, lead to signal transmission to receive the influence, and in the installation, need adopt the screw connection between the lateral wall, also use the screw connection between lid and the lateral wall, need use dedicated instrument to tighten the screw, because the screw quantity is more, need repeat the many times to tighten the screw, the operation is inconvenient, and the operating efficiency is low.
