Furthermore, directional terms, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., in the present invention are used only with reference to the directions of the attached drawings, and are used for better and more clear description and understanding of the present invention, not to indicate or imply the orientations that the present invention must have, and thus should not be construed as limiting the present invention.
The embodiment of the invention is shown in fig. 1 to 3, and the precise fiber dividing and protecting system for the multi-core optical device comprises a multi-core optical device 1 containing a plurality of tail fibers 10, a plurality of optical fiber connectors 2 connected with the tail fibers 10 of the multi-core optical device 1 and corresponding to the number of the tail fibers 10, and a baffle 3 arranged between the optical fiber connectors 2 and the tail fibers 10 of the multi-core optical device 1, wherein a plurality of through holes 30 which are arranged at intervals and used for the tail fibers 10 of the multi-core optical device 1 to pass through are arranged on the baffle 3, and the diameter of each through hole 30 is smaller than the size of a connecting end of the optical fiber connector 2 connected with the tail fibers 10 of the multi-core optical device 1. During assembly, the tail fibers 10 of the multi-core optical device 1 are uniformly separated, then the tail fibers 10 pass through the through holes 30 on the corresponding baffle plates 1, the optical fiber connector 2 is assembled at the tail ends of the tail fibers 10 after the tail fibers 10 pass through the through holes 30, the multi-core optical device 1 is vertically placed after the optical fiber connector 2 is assembled, the baffle plates 3 slide downwards under the action of self gravity or under the action of downward pressure or tension, the optical fibers of the multi-core optical device 1 are separated, and the optical fibers cannot be intertwined. Therefore, the multi-core optical device is accurately split by the baffle plate 3, the optical fibers are prevented from being wound together, the optical fibers are prevented from being broken, and the optical fibers are effectively protected. In order to make the split fibers more accurate and further prevent the fibers from being broken, the through holes 30 are arranged at equal intervals, the through holes 30 arranged at equal intervals uniformly distribute the pressure applied on each split fiber, the split fibers can be stably positioned, the assembly speed is high, the diameter of the through holes 30 is smaller than the size of the connecting end of the optical fiber connector 2 connected with the tail fiber 10 of the multi-core optical device 1, and the problem that the optical fiber connector 2 is penetrated out of the through holes 30 and falls off from the baffle 3 is avoided. The weight of the baffle 3 can be designed according to the force born by each tail fiber 10 and the number of the tail fibers if the baffle 3 slides downwards by utilizing the self gravity. In order to better protect the optical fibers, the number of the through holes 30 is the same as that of the tail fibers 10 of the multi-core optical device 1, so that the problem that the optical fibers are broken due to insufficient through holes 30 or excessive through holes 30, which are difficult to assemble in equipment, of the baffle 3 is avoided, the weight of the baffle 3 is smaller than the sum of the maximum force born by each tail fiber 10 in the tail fibers 10, and is larger than the sum of the air buoyancy born by the baffle 3 when the baffle 3 falls and the friction force between the baffle 3 and the tail fibers 10, and the situation that the baffle 3 is too light to divide the fibers by using self gravity and the optical fibers are broken due to too heavy weight can be avoided.
As shown in fig. 1 to 3, in order to facilitate the free access of the pigtail 10 of the multi-core optical device 1 to the through hole 30 after assembly, so as to adjust the multi-core optical device 1, the baffle 3 is provided with a plurality of openings 31 which are in the same direction and are communicated with the corresponding through hole 30 along the arrangement direction of the through holes 30, and the pigtail 10 can conveniently access in the through hole 30 through the openings 31. Meanwhile, in order to flexibly and freely coil the pigtail 10 in and out during installation in the device, and not easily deviate from the through hole 30, the opening 31 is a folded line type opening, and in order to avoid the pigtail 10 from being scratched during in and out, a first round corner 310 is poured at the outer end of the opening 31. In order to avoid the difficulty of entering and exiting the pigtail 10 caused by the excessively complex opening, the opening 31 is made to be a right-angle folded line type opening.
Further, as shown in fig. 2, the through hole 30 is a circular through hole with a smooth inner wall, and the second round corner 300 is formed at the connection part of the through hole 30 and the opening 31, so that the fiber is not scratched by the sharp corner when the pigtail 10 is positioned in the through hole 30 and enters and exits the through hole 30, and the fiber is effectively protected.
As shown in fig. 1 to 3, since the conventional multi-core optical device includes a plurality of tail fibers, the tail fibers are also fan-shaped, and in order to adapt to the structure, the baffle 3 is a strip-shaped baffle, the through holes 30 are arranged along the long side direction of the baffle, and the baffle 3 is provided with third round corners 32 on the sides perpendicular to the surface of the long side direction and parallel to the long side direction, and the round corners also effectively prevent the optical fibers from being scratched during assembly.
As shown in fig. 2, the baffle 3 is further provided with a fixing mechanism 33 for fixing the baffle 3 during assembly of the device, if the baffle 3 is not provided with the fixing mechanism 33, the baffle 3 moves correspondingly due to shaking or vibration of the device after the baffle 3 is assembled in the device, and the baffle 3 breaks the optical fiber during the movement, thereby affecting the use. In order to simplify the assembly of the product and not to affect the assembly of the optical fiber, the fixing mechanism 33 is a boss which extends from the surface perpendicular to the arrangement direction of the through holes 30 and can be clamped in the device, the boss is easy to be set into different shapes, the structure of the product is not complicated, the boss is easy to be clamped with the device, the fixing mechanism 33 can be a hole which can be penetrated by a screw is arranged on the baffle 3, the baffle 3 can be fixed by using the screw to penetrate through the hole and be connected with the corresponding structure on the device by screw, or a bayonet is arranged at the edge of the baffle 3, so that the baffle 3 can be fixed by being clamped on the protrusion in the device by the similar fixing structure.
