C-S Cable Connector Jaw Segments Core Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for core and stranded (C-S) cables, such as those with screw-on inner sleeves, can be labor-intensive to install and may cause excessive compression on the composite or steel core, potentially damaging it.
Innovation Solution
An electrical connector design featuring jaw segments that directly contact the core and are mounted to an end member with an interlocking connection, where a first sleeve surrounds the jaw segments to retain them together without being directly attached to the end member, preventing excessive compression and facilitating easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-on inner sleeve type connectors are used to prevent excessive compression on composite core, then core protection is improved, but installation becomes labor intensive
Solution Approach 1:
The patent removes the screw-on inner sleeve component from the connector design. Instead, it uses jaw segments with compression elements that directly contact and protect the composite core without requiring a separate inner sleeve that needs to be screwed on, thereby eliminating the labor-intensive installation step while maintaining core protection
Solution Approach 2:
The patent introduces jaw segments as an intermediary component between the end member and the composite core. These jaw segments include compression elements that distribute the compressive force evenly across the core surface, preventing excessive localized compression while eliminating the need for screw-on inner sleeves
2Productivity
If jaw segments directly contact the core, then installation efficiency is improved, but risk of excessive compression increases
Solution Approach 1:
The jaw segments incorporate compression elements with specific geometric features (such as rounded surfaces or distributed contact points) that locally adapt to the core geometry. This ensures uniform pressure distribution across the core surface, preventing excessive localized compression while maintaining direct contact for installation efficiency
Solution Approach 2:
The compression elements are designed with adjustable or compliant properties that allow them to adapt their contact pressure parameters. This enables the jaw segments to apply sufficient holding force for secure installation while automatically limiting the pressure to prevent excessive compression damage to the core

AI summary
An electrical connector including an end member configured to connect the electrical connector to another member; and jaw segments. The jaw segments are configured to be arranged relative to one another to directly contact a core of a core and stranded (C-S) cable. Each of the jaw segments are configured to contact a different outer perimeter segment around the core to combine to substantially surround a portion of the core. The jaw segments are mounted directly with the end member at an interlocking connection of the jaw segments directly with the end member.
