Connector Shield Shell Segmentation for Compact Electromagnetic Interference Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in enhancing electromagnetic shielding effects while maintaining a thinner and smaller shape, with issues in connection reliability due to interference from shield shells and difficulty in visual confirmation of fastening positions.
Innovation Solution
The connector design features a cable introduction part inclined away from the fastening direction, allowing the cable shield shell to be thinner and smaller, and embeds cables within the connector main body for improved visibility and easier attachment, ensuring complete insertion and enhanced electromagnetic shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cable shield shell is made thicker and larger to enhance electromagnetic shielding effect, then the electromagnetic shield effect is improved, but the connector size increases and cannot be made thinner and smaller
Solution Approach 1:
The shield shell is divided into two separate components: a cable shield shell that wraps around the cable and a connector shield shell that covers the connector body. This segmentation allows each shield to be optimized independently - the cable shield can be thin since it only needs to shield the cable, while the connector shield provides additional shielding for the connection area without significantly increasing overall size.
Solution Approach 2:
The cable introduction part is designed to extend in a direction different from the fastening direction, creating a multi-dimensional layout. This allows the cable shield shell to be positioned and oriented in a way that maximizes shielding effectiveness without requiring increased thickness or overall connector volume.
2Device complexity
If the cable introduction part extends above the connector main body along the fastening direction, then the structure is simplified, but the shield shell blocks the outer wall section and prevents complete insertion of the connector
Solution Approach 1:
The cable introduction part is designed with an asymmetric orientation, extending in a direction different from the fastening direction. This asymmetric layout prevents the cable shield shell from blocking the outer wall section during insertion, ensuring complete connector insertion while maintaining structural simplicity.
Solution Approach 2:
The cable introduction part extends in a different dimensional direction than the fastening operation. This spatial separation allows the insertion process to proceed without interference from the shield shell, resolving the conflict between structural simplicity and insertion reliability.
3Object-affected harmful factors
If the cable shield shell is made thicker to improve electromagnetic shielding, then the shielding effect is enhanced, but the connection areas become harder to access and visual confirmation of fastening becomes difficult
Solution Approach 1:
By separating the shielding function into two components (cable shield and connector shield), the connector shield can be designed with openings or transparent sections that allow visual confirmation of fastening operations while the cable shield maintains electromagnetic shielding effectiveness.
Solution Approach 2:
The different extension direction of the cable introduction part creates spatial separation between the shielding structures and the connection areas, improving accessibility for fastening operations while maintaining shielding effectiveness through optimized shield positioning.
