Multi-Cable Connector Fixing Unit Prevents Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-coaxial cable connectors often experience loosening or detachment due to insufficient interference force between coaxial cables and their channels, leading to malfunction in electronic products.
Innovation Solution
A multi-cable connector design featuring a fixing unit with notches that abut against the connecting heads of cable assemblies, providing a secure hold between the main body and the circuit board, using a comb plate with teeth and notches to retain cables and prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If channels are formed in the connector body to receive coaxial cables, then the cable arrangement is simplified, but the interference force between cables and channels is insufficient causing loosening or detachment
Solution Approach 1:
The fixing unit is divided into multiple notches corresponding to each cable position, with each notch providing independent retention. This segmentation allows each cable to be individually secured while maintaining overall structural simplicity and ease of manufacture.
Solution Approach 2:
The fixing unit acts as an intermediary component between the connector body and the cable assemblies. It provides the necessary interference force and mechanical retention that the simple channels cannot achieve, while still maintaining the simplified cable arrangement structure.
2Reliability
If a fixing unit with notches is introduced to improve cable retention, then connection stability is enhanced, but device complexity increases
Solution Approach 1:
The fixing unit combines multiple functions into a single component: it provides cable retention through notches, structural support through the plate body, and positioning through the integrated design. This merging reduces the need for separate retention mechanisms and simplifies the overall assembly process.
Solution Approach 2:
The fixing unit serves multiple purposes simultaneously: it retains multiple cable assemblies, provides structural support, ensures proper positioning, and maintains connection stability. This multi-functionality reduces the need for additional components and simplifies the overall connector design.
