Optical Fiber Assembly Tool for Remote Grip Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for installing remote grip optical fiber connectors are complex and prone to errors, leading to potential fiber breakage and reduced signal performance, with a need for simplified tools that can handle various connector types and cables.
Innovation Solution
An assembly tool with a base, connector cradle, buffer clamp activation shuttle, and activation mechanism that simplifies the process by setting the fiber protrusion length and securing the fiber within the connector, allowing for a single continuous movement to activate the buffer clamp and securing cap, thereby reducing the complexity of the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-step installation methods are used for remote grip connectors, then fiber termination can be achieved, but installation complexity increases and error rates rise
Solution Approach 1:
The patent combines multiple installation functions (fiber stripping, cleaving, connector assembly, and termination) into a single integrated assembly tool. The tool integrates a buffer clamp activation shuttle that automatically clamps the buffer, a protrusion setting mechanism that precisely positions the fiber, and a securing cap mechanism that seals the connector, eliminating the need for multiple separate tools and steps.
Solution Approach 2:
The assembly tool incorporates automatic self-alignment and self-setting features. The protrusion setting mechanism automatically positions the fiber at the correct distance from the ferrule end face, and the buffer clamp activation shuttle automatically clamps the buffer when the fiber is inserted, reducing manual intervention and potential errors.
2Manufacturing precision
If manual fiber protrusion setting is performed, then fiber positioning can be achieved, but installation time increases and consistency decreases
Solution Approach 1:
The assembly tool pre-configures the protrusion setting mechanism with predetermined spacing between the ferrule end face and the protrusion stop. This allows the fiber protrusion distance to be automatically set to precise values (e.g., 0.5mm, 1.0mm, 1.5mm) without manual measurement or adjustment during installation, ensuring consistency and speed.
3Adaptability or versatility
If multiple separate tools are used for different connector types, then specialized functionality is achieved, but technician training time increases and efficiency decreases
Solution Approach 1:
The assembly tool is designed with universal adaptability to accommodate multiple connector types (SC, LC, FC, ST) and various fiber cable types (single-mode, multi-mode, different buffer diameters). The tool includes adjustable components and interchangeable fixtures that allow a single tool to perform functions previously requiring multiple specialized tools, reducing training time and improving technician efficiency.

AI summary
An assembly tool for terminating an optical fiber with an optical fiber connector comprises a base having a connector cradle to hold said connector, a buffer clamp activation shuttle slideably disposed on the base to push a sleeve over a buffer clamp of the connector, and an activation mechanism pivotally mounted to the base. The activation mechanism includes an actuation lever to press a securing cap over a mechanical element in the connector, and a drive shaft coupled to the actuation lever. Moving the actuation lever from a first position to a second position activates the buffer clamp activation shuttle and presses the securing cap over the mechanical element.
