Coaxial Cable Connector Crimping Force Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial cable connectors face issues with crimping large cables due to dispersed force application, leading to inadequate coverage and potential defective crimping, as the mounting surface and crimping pieces' folds are in the same plane, causing the crimping pieces to be driven apart.
Innovation Solution
The coaxial cable connector design positions the imaginary plane through the crimping pieces' folds closer to the opposed faces than the mounting surface, allowing effective force application in the facing direction, with angled crimping pieces and recessed grooves to ensure proper crimping of larger cables, and includes recessed and convex portions for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mounting surface and folds are positioned in substantially the same plane, then the structure is simplified, but the crimping force is dispersed and inadequate for large coaxial cables
Solution Approach 1:
The patent repositions the imaginary plane through the folds closer to the opposed faces than to the mounting surface, creating a spatial separation in the facing direction. This dimensional adjustment allows the crimping pieces to effectively concentrate force on large coaxial cables while maintaining structural simplicity, resolving the contradiction between structural simplicity and force concentration.
2Reliability
If the crimping pieces are rotated to crimp the core wire, then the connection is secured, but the crimping pieces are driven away from each other for large cables
Solution Approach 1:
The patent introduces an imaginary plane as a reference intermediary that passes through the folds and is positioned closer to the opposed faces. This intermediary plane serves as a geometric constraint that prevents the crimping pieces from being driven apart during rotation, while still allowing reliable crimping of large coaxial cables.
3Force
If the imaginary plane through the folds is positioned closer to the opposed faces, then force application is effective for large cables, but the structural configuration becomes more complex
Solution Approach 1:
The patent changes the positional parameter of the imaginary plane relative to the folds, specifying that it passes through the folds and is closer to the opposed faces than to the mounting surface in the facing direction. This parameter change optimizes force application effectiveness for large coaxial cables while maintaining a clear, definable geometric relationship that limits complexity.

AI summary
The connector involves a terminal, a housing that supports the terminal, and an outer conductor shell covering at least a portion of the exterior of the housing. The terminal involves a mounting surface exposed from the housing. The housing involves paired crimping pieces provided on opposed sides sandwiching the mounting surface to permit rotation toward the mounting surface, centered about folds. The respective paired crimping pieces include opposed faces that are opposed to the mounting surface when the paired crimping pieces are rotated and abutting faces brought into abutment against counterpart crimping pieces when the paired crimping pieces are rotated. An imaginary plane passing through folds provided on opposed sides that sandwich the mounting surface is positioned in closer proximity to the opposed faces than to the mounting surface in the facing direction in which the mounting surface and the opposed faces are opposed when the paired crimping pieces rotate.
