Multi-port Cable Connector Two-stage Retention Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-port cable connectors require disconnecting the entire gang connector to access and maintain individual cables, disrupting service to all connected cables, as the retention clips are not accessible while connected to a headend.
Innovation Solution
A multi-port cable connector with two-stage retention clips that allow individual cable connectors to be installed and removed without disconnecting the entire unit, featuring clips that can be slid between a first and second stage within the connector housing, enabling access from behind the connector for maintenance without removing it from the headend.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-density multi-port cable connectors are used to connect multiple cables simultaneously, then connection efficiency is improved, but individual cable maintenance requires disconnecting the entire connector
Solution Approach 1:
The retention mechanism is segmented into two independent stages: a first retention clip that secures the gang connector housing to the headend, and second retention clips (one per cable) that secure individual cables to the housing. This segmentation allows the first clip to remain engaged while individual second clips can be independently released for cable maintenance.
Solution Approach 2:
The retention system transitions from a static, all-or-nothing connection to a dynamic, selectively releasable system. The second retention clips are designed to be movable between an engaged position (securing the cable) and a disengaged position (releasing the cable), while the first retention clip maintains the overall connector connection throughout.
2Ease of operation
If retention clips are made accessible for individual cable removal, then cable maintenance becomes easier, but the connector structure becomes more complex
Solution Approach 1:
The retention clips are segmented into two functional groups with distinct accessibility requirements. The first retention clip is positioned for bulk connector attachment/detachment, while the second retention clips are positioned individually for cable-specific maintenance. This segmentation allows each clip type to be optimized for its specific function without compromising the other.
Solution Approach 2:
The second retention clips are positioned in a location that provides access from a direction perpendicular to the main connector interface. This dimensional change in access path allows individual cable maintenance without requiring removal of the entire connector from the headend, effectively adding a new dimension of operational flexibility.
