Dual-Shield High-Voltage Connector for EMI Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors lack an effective electromagnetic shield to reduce interference between connected components.
Innovation Solution
The electrical connector features a dual-shield design with separable first and second shields, each having tabs that engage on opposite sides, and a connector position assurance mechanism to secure the shields in place, enhancing electromagnetic interference reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single shield is used in the electrical connector, then the structure is simple, but the electromagnetic interference reduction is insufficient
Solution Approach 1:
The shield is divided into a first shield portion and a second shield portion that are separable from each other. Each portion can be independently positioned and secured within the connector housing, providing enhanced electromagnetic shielding coverage while maintaining manageable structural complexity through modular design
Solution Approach 2:
The dual-shield configuration adds a dimensional aspect to the shielding structure by layering multiple shield portions within the connector cavity. This multi-layer approach creates overlapping electromagnetic barriers that more effectively block interference from multiple directions
2Object-affected harmful factors
If shields are added to reduce electromagnetic interference, then shielding effectiveness improves, but the connector structure becomes more complex
Solution Approach 1:
The first and second shield portions are combined within the same connector housing structure, working together as an integrated shielding system. The shield portions engage with common mounting features and work in conjunction with the connector position assurance mechanism, merging multiple shielding functions into a unified structural solution
Solution Approach 2:
The connector position assurance mechanism serves multiple functions: it secures the terminal housing, positions the shield portions correctly, and maintains the separated configuration of the first and second shield portions. This multi-functional component reduces the need for additional separate securing mechanisms

AI summary
An electrical connector includes a connector housing. The connector housing defines a connector cavity. A terminal housing is disposed within the connector cavity. A shield is disposed within the connector cavity and is at least partially between the terminal housing and the connector cavity. The shield extends from a connection end to a contact end. The shield includes a first shield that extends from the connection end to the contact end. The shield also includes a second shield that is separable from the first shield and that extends from the connection end to the contact end. The first shield has a first side and a second side. One or more tabs on the first side engage the second shield. The second shield has a first side and a second side. One or more tabs on the second side of the second shield engage the first shield.
