USB Connector Middle Partition for High-Frequency Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB Type-C connectors fail to meet high-frequency specifications due to inadequate separation between the upper and lower rows of terminals, leading to issues with signal interference and high-frequency characteristics during testing.
Innovation Solution
The improved USB connector design incorporates a middle partition with a tongue part and contact parts of equal width, positioned between the upper and lower terminal rows, enhancing isolation and reducing signal interference through a structured configuration that includes spring arms and protective elements for improved signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a baseboard component is positioned between the upper row of terminals and the lower row of terminals, then the connector structure is formed, but the separation between terminal rows is insufficient leading to signal interference
Solution Approach 1:
The baseboard component is segmented into an upper baseboard portion and a lower baseboard portion that are separated from each other. This segmentation creates distinct isolation zones for the upper row of terminals and the lower row of terminals, effectively preventing electromagnetic interference between the two rows while maintaining proper connector structure and functionality.
2Reliability
If the baseboard component is positioned between the terminal seats, then structural support is provided, but the isolation effect is insufficient for high-frequency testing standards
Solution Approach 1:
The baseboard component is divided into upper and lower portions that are separated, creating distinct isolation zones. This segmentation enhances the electromagnetic shielding effect between the upper row of terminals and the lower row of terminals, ensuring compliance with high-frequency testing standards such as IMR and IRL while maintaining structural support.
Solution Approach 2:
The upper baseboard portion is specifically designed to isolate the upper row of terminals from the lower baseboard portion, which in turn isolates the lower row of terminals. This localized quality enhancement at critical interference zones ensures optimal electromagnetic isolation where it is most needed, meeting high-frequency performance requirements.

AI summary
An improved structure of a Universal Serial Bus (USB) connector is provided. The improved structure of the USB connector includes: a middle partition, including a base part and a tongue part extending from the base part; an upper row of terminals disposed above the base part, wherein the upper row of terminals have a first contact part having a first width and extending to the tongue part; and a lower row of terminals disposed under the base part, wherein the lower row of terminals have a second contact part having a second width and extending to the tongue part, wherein the tongue part has a third width, and the first width, second width and third width have the same distance.
