Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to multi-fiber push-in optical cables. Background Technology

[0002] MPO optical cable, short for Multi-fiber Push-On, is a high-density optical fiber connection solution. Its core lies in the use of MPO connectors, which can integrate multiple optical fibers in a single interface to achieve high-speed, high-capacity data transmission.

[0003] Traditional MPO connectors only use integral bundle crimping or unconstrained storage methods. During manual assembly, multiple optical fibers are easily tangled and misaligned, and the positioning is unstable. This not only increases the difficulty of sorting and reduces the accuracy of fiber threading, but also easily causes damage to the fiber coating and bending of the fiber core. It also increases the assembly error rate and reduces the assembly efficiency.

[0004] Therefore, a solution is needed. Summary of the Invention

The partition plate 13 is arranged inside the main carding port 12. The limiting groove 14 is circular and is arranged through the four corners of the carding block 1 11. The collar 15 is arranged at the rear end of the main carding port 12. The tail sleeve 16 is arranged on the collar 15. The top plate 17 is vertically arranged at the front end of the carding block 1 11 and is located at each upper and lower... Between the two limiting grooves 14, a buffer pad 18 is set at the front end of each top plate 17. Two rows of secondary combing ports 110 are equidistantly arranged inside the combing block 19. An anti-slip sleeve 111 is set inside each combing port 110. A limiting groove 112 is set inside the combing block 19, corresponding to the position of each limiting groove 14. A top plate 113 is set at the front end of the combing block 19, corresponding to the position of each top plate 17. A buffer pad 114 is set at the front end of each top plate 113.

[0045] The glass 35 has a rectangular structure and is made of tempered aluminum silicon material. The perimeter of the glass 35 is the same as the perimeter of the recessed gap of the mounting groove 34.

[0046] Solution Analysis:

[0047] 1. Significantly improved fiber sorting and positioning accuracy

[0048] Three-level progressive combing: Through the three-level structure of combing block 11 (cross-shaped partition 13 partitions), combing block 2 19 (single strand independent fixation), and combing block 3 115 (array hole 117 precise docking), the problem of multi-strand fiber optic twisting and disorder in traditional MPO connectors is completely solved.

[0049] Orderly fiber splitting: The process of optical fiber going from "strands" to "single fibers" is clearly defined, and each optical fiber has a clear installation path, which greatly reduces fiber insertion misalignment and improves assembly accuracy.

[0050] 2. Effectively reduces the risk of fiber optic damage.

[0051] Independent fixing: Anti-slip sleeve 111 and tube sleeve 118 wrap and fix the optical fiber in sections, avoiding mutual friction and pulling of the optical fiber during combing and threading, and protecting the coating layer and fiber core.

[0052] Optimized operating space: The operating space reserved between combing block 2 19 and combing block 3 115 allows for direct manual operation, avoiding indirect damage to the optical fiber due to insufficient operating space.

[0053] 3. Assembly efficiency and product qualification rate have been greatly improved.

[0054] Streamlined operation: The steps of stranding, fixing, locking, threading, and sealing are clear and specific, eliminating the need for workers to spend a lot of time sorting out messy optical fibers and significantly shortening assembly time.

[0055] Visual monitoring: The glass window 35 on the sealing sleeve 31 allows direct observation of the internal fiber status during subsequent maintenance, which facilitates timely detection of problems, reduces rework, and improves the product qualification rate.

[0056] 4. Enhanced connection stability and environmental adaptability

[0057] Reliable locking: The mechanical locking structure between the through rod 21 and the screw sleeve 23 ensures that the three-stage comb block will not shift under vibration, tension and other working conditions, thus guaranteeing the long-term stability of the internal optical fiber position.

[0058] Sealing and protection: The sealing sleeve 31 provides a physical barrier against dust and water, improving the connector's adaptability to harsh environments and extending its service life.

[0059] Working principle:

[0060] During fiber splitting and installation, the optical cable is first stripped open, and then the internal fiber strands (each strand containing several optical fibers) are divided into four equal parts. Each fiber strand passes through the gap separated by the partition 13 until the inner end of the split optical cable is locked against the rear half of the main combing port 12 for fixation. The four stripped fiber strands are then inserted towards the front end and evenly distributed into the interior of each anti-slip sleeve 111, with each anti-slip sleeve 111 receiving and fixing one fiber. After completion, the four through rods 21 are passed from front to back through the combing block 2 19 and the combing block 11 (the through rods 21 and the combing block 3 115 are integrally formed). After each buffer pad abuts against the front combing block, the screw sleeves 23 are tightened at each thread 22 to complete the overall fixation. The separated optical fibers are then evenly divided into individual strands and distributed to each array hole 117 in its corresponding area, according to the position of each fiber. Simultaneously, the inner end of each fiber is wrapped and secured inside each sleeve 118. The fibers are installed systematically from bottom to top (there is enough space between the combing block 3 115 and the combing block 2 19 to accommodate two fingers without affecting installation). After all the fibers are installed, the sealing sleeve 31 is pushed in from front to back to enclose the entire combing mechanism 1 and fixing mechanism 2, preventing dust from entering. The internal fiber condition can be observed through the glass 35, facilitating subsequent maintenance and repair.

[0061] Technical effects of implementing this solution:

[0062] This solution constructs a complete multi-fiber assembly solution through a three-stage progressive combing mechanism, a fixing mechanism with threaded screw sleeves, and a sealing mechanism with visible sealing. It fundamentally solves the core pain points of traditional MPO connectors, such as fiber entanglement, unstable positioning, susceptibility to damage, and low efficiency. While improving assembly accuracy and efficiency, it enhances product stability and durability, providing more reliable and efficient technical support for high-density fiber optic connections.

These components are all general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that traditional MPO connectors only use integral bundle crimping or unconstrained storage methods. During manual assembly, multiple optical fibers are easily tangled and misaligned, resulting in unstable positioning. This increases the difficulty of combing, reduces fiber threading accuracy, and easily causes damage to the fiber coating and fiber core bending. It also increases the assembly error rate and reduces assembly efficiency. This invention constructs a complete multi-fiber assembly solution through a three-stage progressive combing, threading screw locking, and a sealing and visual mechanism. It fundamentally solves the core pain points of traditional MPO connectors, improves assembly accuracy and efficiency, enhances product stability and durability, and provides more reliable and efficient technical support for high-density fiber optic connections.
