Cable Holding Member With Insulated Latch Cover for Dielectric Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector devices face dielectric breakdown issues due to the exposure of cable ends, which is exacerbated by stricter dielectric withstanding voltage requirements.
Innovation Solution
A cable holding member with an insulated cover portion that can be bent to cover the cable insertion plane, featuring a cantilever elastic piece for latching, preventing dielectric breakdown and secure attachment to the main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable end is left exposed in the through-hole for easy cable insertion, then the ease of operation is improved, but dielectric breakdown occurs between the cable end and shielding members
Solution Approach 1:
The insulated cover portion is pre-formed as an integral part of the main body and automatically covers the cable insertion plane when the cable is inserted. The cover portion is positioned in advance to prevent dielectric breakdown before it can occur, eliminating the need for separate protective components while ensuring reliable electrical insulation.
2Reliability
If a cover portion is added to prevent dielectric breakdown, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The insulated cover portion is merged with the main body as an integral formed structure, eliminating the need for separate protective components. This integration reduces the total number of parts, simplifies assembly, and lowers manufacturing complexity while effectively preventing dielectric breakdown between the cable end and shielding members.
3Reliability
If a latching mechanism is added to secure the cover portion, then the reliability of attachment is improved, but the ease of operation deteriorates
Solution Approach 1:
The elastic piece automatically latches the cover portion to the main body through its inherent elasticity, without requiring manual intervention or additional fastening operations. The cover portion self-secures upon installation, and can be easily released by applying minimal force to overcome the elastic retention, achieving both secure attachment and ease of operation.
