Optical Fiber Fusion Splicer V-Shaped Guiding Groove Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber fusion splicers struggle to securely clamp bare fibers at the distal end portions of optical fibers due to warping, leading to misalignment during fusion splicing.
Innovation Solution
The optical fiber fusion splicer employs a pair of bare fiber holding members with a fiber positioning member and a fiber clamping member, featuring V-shaped and inverted-V-shaped concave guiding portions to guide and press the bare fibers into the groove, ensuring secure reception and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber clamps are used to clamp bare fibers, then the bare fibers can be held in place, but the bare fibers may be disposed obliquely with respect to the V-shaped grooves due to warping and thus cannot be securely received
Solution Approach 1:
The concave guiding portions are provided in advance to guide the bare fiber into the V-shaped groove before clamping occurs. The guiding portions create a preliminary alignment path that ensures the bare fiber is properly positioned in the groove before the fiber clamp applies clamping force, preventing oblique disposal due to warping.
Solution Approach 2:
The concave guiding portions act as an intermediary element between the bare fiber and the V-shaped groove. This intermediary structure facilitates the transition of the bare fiber from an oblique position to a properly aligned position in the groove, making the alignment process easier and more reliable.
2Manufacturing precision
If multiple guiding portions and pressing members are added to improve fiber alignment, then fiber positioning accuracy improves, but the device structure becomes more complex
Solution Approach 1:
The fiber positioning member and fiber clamping member are combined into a single integrated bare fiber holding member. The concave guiding portions are integrated into the positioning member, and the pressing surface is integrated into the clamping member. This merging reduces the number of separate components while achieving precise fiber positioning and clamping.

AI summary
An optical fiber fusion splicer includes positioning members and clamping members. Each clamping member clamps the bare fiber. A first guiding portion protrudes from the top surface of each positioning member and guides a distal end portion of the bare fiber toward the groove. A concave face of the first guiding portion has a V-shaped cross section. Each clamping member includes a second guiding portion, which guides a base portion of the bare fiber toward the groove of the corresponding positioning member, and a pressing member, which presses the bare fiber against the top surface of the fiber positioning member. A concave face of the second guiding portion has an inverted-V-shaped cross section. The fusion splicer can clamp bare fibers while the bare fibers are received by the groove.
