Shielded Connector Assembly for Crosstalk and Resonance Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector assemblies experience significant crosstalk and resonance issues in signal transmission, particularly in board-to-board connectors, leading to reduced bandwidth.
Innovation Solution
The connector assembly design includes first and second connectors with ground terminals and shielding pieces on substrates, where the ground terminals are electrically connected to each other and to shielding pieces, and signal terminals are directly connected, reducing crosstalk and resonance through enhanced electrical connections and increased impedance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is designed to be fully submersible in fluid environments, then water ingress protection is improved, but manufacturing complexity increases due to requiring a fluid-tight barrier between disconnecting components
Solution Approach 1:
The connector is divided into separate first and second portions that can be disconnected, with each portion having its own sealing structure. The first portion includes a first seal and the second portion includes a second seal, allowing independent sealing of each segment rather than requiring a complex barrier across the entire connector interface.
Solution Approach 2:
A fluid-tight barrier is introduced as an intermediary element between the first and second portions of the connector. This barrier prevents fluid communication between the portions while allowing electrical connections to be maintained or established, solving the problem of preventing water ingress without requiring the connector housing itself to be completely sealed.
2Ease of operation
If a connector allows disconnection between components, then ease of operation is improved, but risk of fluid ingress increases when disconnected
Solution Approach 1:
Sealing structures are pre-configured on both the first and second portions of the connector before disconnection occurs. The seals are positioned to automatically engage and prevent fluid ingress as soon as the connector portions are separated, eliminating the need for additional protective actions during disconnection.
Solution Approach 2:
The fluid-tight barrier acts as an intermediary that maintains fluid separation even when the electrical connections are disconnected. This barrier allows the connector to be disconnected for operation while preventing fluid from entering the connector interior, thus maintaining reliability during disconnection states.
3Adaptability or versatility
If a connector provides both electrical and fluid pathway connections, then functionality is improved, but risk of unintended fluid communication increases
Solution Approach 1:
The electrical and fluid connection pathways are segmented into separate structures within the connector. The electrical contacts are housed in one configuration while the fluid pathway is sealed by a barrier, allowing both functions to coexist without interfering with each other or creating unintended fluid communication channels.
Solution Approach 2:
The fluid-tight barrier serves as an intermediary element that selectively allows electrical connections while blocking fluid pathways. This barrier enables the connector to provide both electrical and potential fluid connections without creating unintended fluid communication, as the barrier can be configured to block fluid while permitting electrical contact engagement.
