Optical Fiber Connector Assembly Crimping Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber connector assemblies have mechanical strength and tensile strength issues due to intermediate mechanical couplings, which increase complexity and production costs.
Innovation Solution
An optical fiber connector assembly design featuring a sleeve to house the ferrule, a connector body with a distal portion for the sleeve and a proximal portion for direct coupling to the fiber optic cable, using a crimping element at the proximal portion to secure the cable, reducing mechanical couplings and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an intermediate mechanical coupling (spring push and crimp band) is used to connect the connector housing to the fiber optic cable, then the assembly allows modular construction and ease of assembly, but the mechanical strength and tensile strength are reduced, exposing optical fibers to possible ruptures
Solution Approach 1:
The invention merges the connector housing and the fiber optic cable assembly into a single integrated unit by directly coupling the cable to the housing without intermediate mechanical couplings. This eliminates the spring push and crimp band, creating a monolithic structure that maintains full mechanical strength while preserving ease of assembly through direct integration.
2Ease of manufacture
If an intermediate mechanical coupling (spring push and crimp band) is used to connect the connector housing to the fiber optic cable, then the assembly allows modular construction, but the complexity of assembling and production operations increases significantly
Solution Approach 1:
The invention merges multiple separate components (connector housing, spring push, crimp band, and cable assembly) into a single integrated structure. This eliminates the need for complex assembly operations involving multiple parts, reducing production complexity while maintaining modular benefits through direct integration of functional elements.
3Adaptability or versatility
If an intermediate mechanical coupling is used to connect the connector housing to the fiber optic cable, then the assembly allows for separate termination of components, but the mechanical strength is reduced
Solution Approach 1:
The invention combines the termination functions directly into the connector housing structure itself, eliminating the need for intermediate coupling components. This integrated approach maintains adaptability for various cable types while preserving full mechanical strength through direct structural coupling between the housing and cable.
