Shielded Connector Sealing for Watertight Electrical Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors used in high voltage/intensity applications face challenges in maintaining shielding continuity while ensuring watertightness, due to difficulties in manufacturing, mounting, and cost considerations.
Innovation Solution
The proposed electrical connector employs an outer shielding means with applied sealing means to ensure watertightness, while also maintaining shielding continuity between a braid and an inner shielding means, using a deep-drawn metal outer shielding and flexible blades for electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an outer shielding means is used to provide shielding continuity, then electrical continuity is improved, but achieving watertightness becomes more difficult
Solution Approach 1:
The patent combines the shielding function and sealing function into a single integrated component - the outer shielding means serves both as an electrical shield and as a mounting surface for sealing means, eliminating the need for separate shielding and sealing components
Solution Approach 2:
The outer shielding means performs multiple functions simultaneously: it provides electromagnetic shielding, serves as a structural support for the sealing means, and contributes to the overall watertight enclosure of the connector
2Reliability
If sealing means are applied onto the outer shielding means, then watertightness is improved, but manufacturing and mounting complexity increases
Solution Approach 1:
The sealing means is pre-mounted onto the outer shielding means during the shielding component fabrication process, so that when the connector is assembled, the sealing function is already integrated and requires no additional separate mounting operations
Solution Approach 2:
The manufacturing processes for creating the shielding means and attaching the sealing means are combined into a single integrated production step, simplifying the overall manufacturing workflow
