Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielded connectors have complex production processes and inadequate high-frequency shielding due to multiple parts and openings that allow interference signals to penetrate or escape.
Innovation Solution
A one-piece shielding housing with a press fit on the cable and a crimp sleeve for improved assembly and high-frequency sealing, eliminating unnecessary openings and using a crimp sleeve to ensure electrical contact and mechanical fixation of the braided shield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a shielding housing is formed from multiple parts with openings for adhesive injection, then assembly flexibility is improved, but high-frequency shielding effectiveness deteriorates due to signal penetration through openings
Solution Approach 1:
The patent merges multiple shielding housing parts into a single integrated one-piece shielding housing structure. This eliminates the need for separate housing halves with adhesive injection openings, thereby maintaining assembly flexibility while achieving continuous high-frequency shielding without gaps or openings that would allow signal penetration.
Solution Approach 2:
The invention extracts and removes the adhesive injection openings from the shielding housing structure. By eliminating these openings entirely, the design achieves complete high-frequency shielding continuity while still providing adequate assembly capabilities through alternative means such as snap-fits or integrated fastening features.
2Ease of manufacture
If a braided shield is left loose without fixation, then cable assembly is simplified, but mechanical stability and electrical contact reliability deteriorate
Solution Approach 1:
The patent incorporates a fixation structure for the braided shield that is pre-integrated into the shielding housing design. This preliminary structural provision allows the braided shield to be easily fixed during assembly without complex additional steps, thereby maintaining assembly simplicity while ensuring reliable mechanical stability and consistent electrical contact.
3Ease of manufacture
If openings are provided in the shielding housing for adhesive injection, then manufacturing processability is improved, but interference signal shielding deteriorates
Solution Approach 1:
The patent combines the functions of shielding and adhesive application into the one-piece housing structure. Adhesive is applied to specific localized areas of the integrated housing rather than through openings, eliminating interference signal penetration paths while maintaining manufacturing processability through precise adhesive placement on the unified structure.
