Optical Fiber Connector Positioning Mold Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber lines frequently fracture during positioning in conventional molds, leading to low yield rates and difficulty in removing fractured fibers, which hampers the productivity of optical fiber connectors.
Innovation Solution
A positioning mold design featuring a lower mold board with positioning pins and through apertures, combined with a thin board having optical fiber positioning apertures and fastening elements, allows for secure engagement and easy removal of optical fiber lines, using materials like plastic, metallic, or celluloid, and formed via methods like laser cutting or etching to facilitate smooth positioning and demolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional positioning molds with embedded positioning blocks are used, then optical fiber connectors can be manufactured, but optical fiber lines fracture easily and cannot be removed easily
Solution Approach 1:
The positioning mold is divided into separable components: a lower mold board and an upper mold board that can be detached from each other. The optical fiber positioning aperture is formed by the cooperative positioning of these two boards, allowing the upper board to be removed after positioning, enabling easy extraction of optical fiber lines while maintaining positioning accuracy during the process
Solution Approach 2:
The optical fiber positioning aperture structure is extracted from the traditional embedded block design. Instead of having permanent embedded positioning blocks, the patent uses a removable upper mold board that creates the positioning aperture only when engaged with the lower mold board, allowing easy removal of positioned optical fiber lines
2Manufacturing precision
If embedded positioning blocks are used in conventional molds, then positioning can be achieved, but productivity decreases due to fractures and difficulty in removal
Solution Approach 1:
By segmenting the mold into separable upper and lower boards, the patent enables quick removal of the upper board after positioning, significantly reducing the time required for optical fiber line extraction and improving overall production efficiency without compromising positioning accuracy
Solution Approach 2:
The mold structure transitions from a static embedded block design to a dynamic separable design, where the upper mold board can be engaged for positioning and then disengaged for easy removal of optical fiber lines, making the positioning process adaptable and efficient

AI summary
A positioning mold of optical fiber connector includes a lower mold board and a thin board. The lower mold board includes two positioning pins and at least one through aperture. The thin board is arranged above the lower mold board, and is provided with two first through holes and with at least one optical fiber positioning aperture. The two first through holes correspond to two positioning pins, and the at least one optical fiber positioning aperture to the at least one through aperture. Given such structure, even if optical fiber lines fracture inside of the optical fiber positioning apertures during the work of positioning, the fractured optical fiber lines can be taken out and replaced easily, so as to improve the productivity in manufacturing optical fiber connectors.
