Shielded Connector Integral Inner Ring Single Crimp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielded connectors require two crimping steps to secure the shielding member to the shield shell, leading to excess time and labor due to the need to fix the connecting means to the shield shell.
Innovation Solution
A shielded connector design where the inner ring and shield shell are formed integrally via a joint, allowing the shielding member to be secured with a single crimping step by sandwiching it between the inner and outer rings, with a projection and recess configuration to prevent displacement and inclination of the inner ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting means includes separate inner and outer rings that are crimped together, then the shielding member can be securely connected, but two crimping steps are required increasing time and labor
Solution Approach 1:
The inner ring and shield shell are merged into a single integral structure, eliminating the need for separate crimping operations. The inner ring is formed as one piece with the shield shell, so when the outer ring is crimped onto the inner ring, both components are secured simultaneously in a single crimping step.
2Reliability
If the inner ring is separately fixed to the shield shell, then the connecting means can be securely mounted, but the device complexity increases
Solution Approach 1:
The inner ring and shield shell are combined into a single integral component, reducing the number of separate parts. This merging eliminates the need for additional mounting steps and reduces structural complexity while maintaining secure attachment of the shielding member.

AI summary
A shielded connector is provided with a housing (14) for accommodating terminals (13) connected with ends of wires (11), a shield shell (20) for accommodating the housing (14) and connection for connecting an end portion of a shielding member (12) with the shield shell (20). The connection includes a tubular inner ring (25) into which the wires (11) are insertable and around which the end portion of the shielding member (12) is mounted, and an outer ring (29) to be crimped into connection with the outer circumferential surface of the inner ring (25) by sandwiching the end portion of the shielding member (12) between the inner ring (25) and the outer ring (29). The inner ring (25) and the shield shell (20) are integrally formed via a joint (26).
